冲压模具空步英文缩写

冲压模具空步英文缩写Idle Stroke in Stamping Dies.Definition:In the context of stamping dies, an idle stroke refers to the portion of the die cycle during which the punch is retracted from the workpiece without performing any forming operation. It is also known as the "up stroke" or "return stroke".Purpose:The idle stroke serves several important functions in the stamping process:Retracting the Punch: The idle stroke allows the punch to be withdrawn from the workpiece, creating clearance for the removal of the finished part.Resetting the Die: During the idle stroke, the die components are returned to their original positions, preparing them for the next stamping cycle.Allowing Material Flow: The idle stroke provides time for the workpiece material to flow back to its original shape after being deformed by the punch. This helps minimize springback and ensure dimensional accuracy.Cooling the Die: The idle stroke allows the die components to cool down, preventing excessive wear and thermal damage.Design Considerations:The design of the idle stroke is crucial for theoverall efficiency and effectiveness of the stamping die. Key factors to consider include:Stroke Length: The idle stroke length is determined by the clearance required for part removal and the time needed for material flow and die cooling.Acceleration and Deceleration: The acceleration and deceleration profiles of the idle stroke should becarefully designed to minimize shock and vibration that can damage the die or workpiece.Dwell Time: A dwell time may be incorporated into the idle stroke to allow sufficient time for material flow and die cooling.Lubrication: Proper lubrication is essential to reduce friction and wear during the idle stroke.Optimization:Optimizing the idle stroke can improve stamping productivity and reduce downtime. Strategies for optimization include:Reducing Stroke Length: Minimizing the idle stroke length can reduce cycle time and increase productivity.Smoothing Acceleration and Deceleration: Gradual acceleration and deceleration profiles can reduce shock and vibration, extending the lifespan of the die.Minimizing Dwell Time: Reducing dwell time can improve productivity, but it is important to ensure sufficient time for material flow and die cooling.Using High-Performance Lubricants: Employing high-quality lubricants can reduce friction and wear, leading to longer die life and improved part quality.Conclusion:The idle stroke plays a vital role in stamping dies, ensuring the efficient and accurate production of stamped parts. Its design and optimization are critical for maximizing productivity, minimizing downtime, and extending the lifespan of the die.。

简述数字时间戳及其原理。

数字时间戳( Digital(Time-Stamping,DTS)是一种用于证明数据完整性和来源的技术。

它通过将数据与一个精确到毫秒的时间标记相关联,来确保数据的不可篡改性和真实性。

数字时间戳的原理是将数据和时间信息一起加密,生成一个唯一的、不可更改的数字签名。

数字时间戳的工作原理如下:首先,用户需要向时间戳服务器发送要进行时间戳认证的数据。

然后,时间戳服务器会对该数据进行哈希运算,生成一个唯一的哈希值。

接着,时间戳服务器会用自己的私钥对哈希值进行加密,生成一个数字签名。

最后,时间戳服务器将加密后的数字签名和原始数据一起返回给用户。

当用户需要验证数据的真实性时,只需将数据提交给时间戳服务器。

服务器会对数据进行同样的哈希运算,并使用自己的公钥解密数字签名。

如果解密后的哈希值与用户提交的哈希值相同,那么数据就被认为是真实的。

数字时间戳技术通过将数据与精确的时间标记相结合,为数据提供了一种可靠的完整性和来源证明机制。

它在金融、法律、医疗等领域具有广泛的应用前景。

Pendulum CNT-90XL 脉冲RF计数分析仪数据表说明书

Pendulum CNT-90XL 脉冲RF计数分析仪数据表说明书

Counter/Analyzer is an excellent tool for measurement, analysis and calibration of Microwave Frequency, Power, and Pulsed RF time parameters like pulse width and PRI. Whether in test systems, on the R&D bench, in the calibration lab or out in the field, the high-resolution and ultra-fast CNT-90XL is the state-of-the-art Microwave Counter/Analyzer. The NEW option for pulsed RF makes CNT-90XL ideal for radar test and calibration. The CNT-90XL offers a unique ease-of-use with graphical display and improved control over measurement at an affordable price.The Fastest Microwave CounterThe CNT-90XL Microwave Counter/Analyzer sets a new industry standard for microwave frequency analysis and outperforms any microwave Pulse or CW counter on the market regarding resolution, speed and acquisition time. The CNT-90XL is the worlds fastest Microwave counter and offers a measurement speed up to 250,000 frequency samples/s, for advanced statistical analysis, and for analysis of frequency or power transients.The NEW Pulsed RF option enables measurements of pulses down to 30 ns width, plus PRI/PRF, frequency in burst and power in burst.The multi-functional CNT-90XL also serves as a 400 MHz general purpose timer/counter, with unique ease-of-use with analysis capabilities to view variations in signal parameters both numerically and graphically.Save money in production testThe CNT-90XL is intended for several applications, such as:• Pulsed, Chirped, and Doppler Radar testing and calibration• Microwave link carrier calibration• Satellite communication equipment testing• RF and microwave instrumentation calibration• RF components and modules, including YIG and VCO testing• Medical RF equipment testing Product Features And Benefits• Pulsed RF measurements (optional) includes Pulse Width to 30 ns, PRI/PRF, Frequency in Burst, Power in Burst• Fast high-resolution frequency or power measurements, for modulation, doppler shifts, or transient analysis• Very short acquisition time of 25 ms (Auto) or zero (Manual)• High sensitivity (-33 dBm)• Statistical processing and graphical histogram, trend and modulation display• Affordable microwave frequency countingProduct Features And Benefits• High resolution is vital for R&D and production testing. CNT-90XL meets this requirement with 100 ps single shot (time) or 12 digits/s (frequency). Obtained values are displayed with up to 14 digits.• For calibration purposes, the CNT-90XL offers very high accuracy through stable internal OCXO time base, plus high resolution.• Both USB and GPIB interfaces are standard. With USB you won’t need to invest in a GPIB interface card for your PC. The GPIB operates in either SCPI/GPIB or 53131 emulation mode, for plug-and-play replacement in existing ATE systems.• Menu-oriented settings reduce the risk of mistakes. Valuable signal information, given in multi-parameter displays, removes the need for other instruments like DVM’s and Scopes.Battery OptionThe CNT-90XL has an optional battery pack with 90 Wh capacity, capable of mains-free operation for at least 4.5 hours. In stand-by mode the battery pack can keep an OCXO warm and running for over 24 hours. Battery operation of a frequency counter/analyzer is valuable in three different applications:• Transportation of high-stability OCXO to maintain stability, which gives instant use at destination without any warm-up time• Battery backup acting as a built in UPS (Uninterrupted Power Supply)TimeView®, Modulat ion Domain Analysis SWThe optional Modulation Domain SW TimeView® is the ultimate tool to view and analyze dynamic frequency changes in real-time, utilizing the high-resolution PC screen, marker read-outs and processing, FFT calculation to find modulation frequencies, ADEV calculation of short-term stability and more.Excellent Graphical PresentationOne of the great features of the CNT-90XL is the graphical display and the menu oriented settings. The non-expert can easily make correct settings without risking costly mistakes. The multi-parameter display shows auxiliary measurement values such as Power level in dBm in Frequency measurements.Measurement values are presented both numerically and graphically. The graphical presentation of results (histograms, trends etc.) gives a much better understanding of the nature of signal jitter. It also provides you with a much better view of changes vs time, from long term trends like slow drift, to fast modulation and transients. Three statistical views of the same data set can be viewed: Numerical, Histogram and Modulation/T rend. It is very easy to capture and toggle between views of the same data.When adjusting a frequency source to given limits, the Limit qualifying tool gives fast and accurate visual guidance. T olerance limit markers are visually displayed and the actual frequency is graphically displayed inside or outside the limit markers. Passing the limits will cause an alarm indication.The graphical display examples below show the frequency changes over time directly on-screen, for example Doppler frequency shift in speed radar sensors, fast power switching, FM or AM. Builtin statistical processing presents numerical stability data and also frequency distribution histograms on-screen for analysis of frequency stability or modulation.Figure 2:Pulse modulated frequency or FSKFigure 3:Generator start-up power settlingFigure 4:Very small AM on carrier is visualizedFigure 5:Numeric statistics screen of the previous AM signalFigure 6:Power step from generator (-30 to -5dBm in 5dBm steps) NOTE: output is turned off shortly betw. power stepsFigure 7:Power step (close up)Figure 1:1kHz FM with 12 ppm modulation depthMeasuring FunctionsFrequency A, B, CRange:Input A, B: 0.002 Hz to 400 MHzInput C: 300 MHz to 27, 40, 46 or 60 GHz Resolution: 12 digits in 1s measuring time Acquisition C: Auto or ManualAcquisition time: 25 ms in Auto (typ.)*Note: Some frequencies may not be acquired correctly with Auto Acquisition.

Pendulum CNT-91 零死时计数器产品说明书

Pendulum CNT-91 零死时计数器产品说明书

The Pendulum CNT-91 zero-dead-time counter features continuous data streaming of measurements over GPIB/USB during, not after, measuring; creating a dynamic measurement/analysis system, a fi rst in the counter industry! The CNT-91 is a unique frequency analyzer, outperforming any universal timer/ counter.Highest Performance Ever• High GPIB/USB bus speed reduces test time in ATE test systems. Individual measurements up to 4k meas/sec in talker only mode. Fast Block measurements with continuous data streaming.• Z ero-dead-time counting provides period/frequency back-to-back measurements and the correct calculation of Allan Deviation.• H igh resolution is critical for R&D and production testing. 50 ps single shot (time) or 12 digits/sec. (frequency) resolution allows capturing very small time and frequency changes, displayed to14 digits.• M odulation Domain Analysis (MDA). With TimeViewTM SW, the CNT-91 becomes a high-performance MDA. Thanks to the high measurement speed (250k meas/sec.) and large memory depth (3.75M) of these, very fast frequency changes in real time can be captured.• C NT-91’s integrated programmable pulse output offers 0.5Hz to 50 MHz fast rise time signals as a reference frequency output,external pacing/trigger source, or general purpose pulse source.Outstanding Performance/Price RatioThe CNT-91 timer/counter/analyzer outperforms every counter on the market, independent of measurement task.• The graphic presentation of results, histogram, trend line, numerical statistics, modulation domain – provide a clearer understanding of random signal distribution and measurement changes over time – from slow drift to fast jitter, and modulation.• B oth USB and GPIB interfaces are standard. With USB you won’t need to invest in a GPIB interface card for your PC. The GPIB operates in either SCPI/GPIB or 53131/53132 emulation mode, for plug-and-play replacement in existing ATE systems.• W ide frequency range - to 20 GHz – offers microwave CW frequency measurements and very short burst measurements down to 40 ns.• M enu-oriented settings reduce the risk of mistakes. Valuable signal information, given in multi-parameter displays, removes the need for other instruments like DVM’s and Scopes.The high-performance CNT-91 is the only tool you need for time & frequency measurement, analysis, and calibration.CNT-91R Frequency Calibrator/AnalyzerThe CNT-91R Frequency Calibrator/Analyzer is an all-inclusive high performance calibrator of frequency sources, that combines the high resolution measurements and advanced analysis of CNT-91, with a built-in ultra-stable Rubidium atomic reference clock. Its compact format, and its short warm-up time, makes the CNT-91R an ideal transportable one-box frequency calibrator/ analyzer.Excellent Graphical PresentationOne of the great features of the CNT-91 is the graphical display and the menu oriented settings. The non-expert can easily make correct settings without risking costly mistakes.The multi-parameter display with auxiliary measurement values such as Vmax/Vmin/Vp-p in frequency measurements, and frequency/ attenuation/phase, eliminates the need for extra test instruments and provides direct answers to frequently asked questions, like “What is the attenuation and phase shift of this fi lter?” Measurement values are presented both numerically and graphically. The graphical presentation of results (histograms, trends etc.) gives a much better understanding of the nature of jitter. It also provides you with a much better view of changes vs time, from slow drift to fast modulation (trend plot). Three statistical views of the same data set can be viewed: Numerical, Histogram and T rend. It is very easy to capture and toggle between views of the same data (see fi gure 4, 5 & 6).When adjusting a frequency source to given limits, the graphic display gives fast and accurate visual calibration guidance.CNT-91/91R vs CNT-90 selection chartFeature CNT-91/91R CNT-90 Graphic display of trend, histogram,modulation domain yes yes Frequency resolution12 digits/sec12 digits/sec Time resolution (single shot)50 ps100 ps Voltage resolution1mV 2.5mVMeasurement speed to internal memory250k meas/sec3.75M results 250k meas/sec 750k resultsTalker only output (GPIB/USB)4k meas/sec no Individually triggered measurements650/sec500/sec Block transfer speed15k meas/sec5k meas/sec Freq, period, time, phase, volt, duty c,pulse w, rise time yes yesT otalize, TIE yes no Programmable pulse output yes no Continuous measurements yes no Timebase CNT-91OCXO (opt)OCXO (opt) Timebase CNT-91R OCXO (opt)OCXO (opt)Figure 1:Display showing phase value, frequency, attenuation Va/Vb,and auxiliary parameters.Figure 2:Measure function selection menu, shown with measured results.Figure 3:Input parameter setting menu shown with measured result.Figure 4:Display showing different statistical parameters viewed at thesame time.Figure 5:Display showing the trend (signal over time) of sampled data.Figure 6:The same result as in Figure 5, now displayed as a histogram.Measuring FunctionsAll measurements are displayed with a large main parameter value and smaller auxiliary parameter values (with less resolution).

Further, upgrad-ing to a high-performance oscillator, such asa Rubidium atomic clock, keeps SyncServerS650 accurate for long periods in the eventof a GNSS service disruption.Secure NetworkingSecurity is an inherent part of SyncServerS650. In addition to many security featuresand protocols, services can be selectivelydisabled. The four standard GbE ports, andtwo optional 10 GbE ports, can accommo-date 10,000 NTP requests per second usinghardware time stamping and compensa-tion. NTP monitoring, charting and MRUlogging assist in managing the NTP clientactivity. For more secure NTP operations,enable the optional security-hardened NTPReflector™ with line speed, 100% hardware-based NTP packet processing.Leverage Built-In HardwareSyncServer S650 includes many built-inhardware features enabled throughsoftware license keys, such as the security-hardened NTP Reflector, Galileo/GLONASS/BeiDou/QZSS support, and multi-port/pro-file IEEE 1588 PTP output/input operations.SyncServer S650, the future of time andfrequency, today. Four GbE Ports for Performance, Flexibility and SecurityThe S650 has four dedicated and isolated GbE Ethernet ports, each equipped with NTP hardware time stamping. These are connected to a high-speed microprocessor with microsecond-accurate timestamps to assure high-bandwidth NTP performance. This exceeds the need of servicing 10,000 NTP requests per second with no degrada-tion in time stamp accuracy.Multiple ports provide the flexibility to adapt to different network topologies as networks grow and change. An S650 can be the single time source to synchronize clients on different subnets and physi -cal networks. There is only one time reference, but it can appear as though there are four clocks available because each port is independent.NTP can be served on all four ports (six if 10 GbE ports are added). The highly secure web-based management interface is only available on port 1, so that administrators may choose to keep that IP address private and secure. Unique access control lists per port can govern server response to client requests for time.Intuitive, Secure and Easy-to-Use Web InterfaceThe modern web interface is the primary control interface of the S650. Once the keypad and display bring the unit online, complete status and control functions are easily found on the left navigation menu. A REST API also included.Standard Management Access SecurityAll of the expected network management protocols are standard in the S650. These include mandatory password access, HTTPS/SSL only (using the high-encryption cipher suite), SSH, access control lists, ser-vice termination, SNMPv2/v3, and NTP MD5 authentication. All traffic to the S650 CPU is bandwidth-limited for protection against DoSattacks. The local keypad on the server can be password-protected to prevent tampering.Security-Hardening OptionThe SyncServer S650 can be further hardened from both an NTP perspective and an authentication perspective through the Security Protocol License option that includes the security-hardened NTP Reflector.Operational hardening through the 360,000 NTP packet per second NTP Reflector with 100% hardware-based NTP packet processing also works with a CPU-protecting firewall by bandwidth limiting all non-NTP traffic. The Reflector also monitors packet flow for DoS detection and reporting, yet remains impervious to the level of network traffic as it operates at line speed.Authentication hardening is available for NTP client/server authenti-cation through the NTP Autokey function or user access authentica-tion through TACACS+, RADIUS and LDAP. Third party CA-signed X.509 certificates are installable for further hardening of manage -ment access and secure syslog operations. For more information about the Security Protocol License option, see the SyncServerOptions datasheet.The four GbE ports provide network configura -tion flexibility and enhanced security. Multiple isolated and synchronized time servers can also be configured. Two 10 GbE SFP+ ports can be added for NTP/PTP operations as well.At-a-glance dashboard presentation combined with logical organization andintuitive controls that make configuring the S650 easy.An entire drop-down menu in the S650 dedicated to security-related protocols.Unprecedented NTP AccuracyThe Stratum 1 level S650 derives nanosecond-accurate time directly from the atomic clocks aboard the GPS satellites. By using an integrated, 72-channel GNSS receiver, every visible satellite can be tracked and used to maintain accurate and reliable time. Even in urban canyon environments where direct satellite visibility can be limited, manually inputting the position can be sufficient to acquire accurate time from as few as one intermittent satellite.Ultra-High Performance NTPThe S650 can effortlessly support hundreds of thousands of network clients while maintaining microsecond-caliber NTP time stamp accuracy. NTP request throughput rates can exceed 10,000 requests/ second while maintaining NTP time stamp accuracy. NTP monitoring, charting and MRU logging assist in managing the NTP client activity. If the Security Protocol License option is enabled, the NTP Reflector can process over 360,000 NTP requests per second with 15-nanosecond caliber time stamp accuracy with the added benefit of security-hardening the network port.Superior Low Phase Noise PerformanceThe S650 can be optimized to provide the best possible low phase noise 10 MHz signals. Two LPN modules are available to choose from depending on the phase noise sensitivity of the user application. Each module has eight extremely isolated 10 MHz LPN outputs with each module offering excellent levels of LPN and Ultra LPN perfor-mance from the close in 1 Hz out to 100 kHz.Multi-Port/Profile IEEE 1588 PTP Grandmaster Applications demanding very precise time accuracy can require the IEEE 1588 precise time protocol (PTP). The S650 PTP Output License enables multi-port/profile PTP grandmaster operations leveraging the built-in hardware time stamping on each LAN port of the S650. IEEE 1588 PTP Input LicensePTP input is useful for tunneling time to the S650 over the network. PTP input can be the primary time reference or used as a backup reference in the event of GPS signal loss. With GPS, the S650 can automatically calibrate and store observed network path delay asym-metries for PTP input use if the GPS signal is lost.Multi-GNSS Constellation Support for Enhanced ReliabilityTiming integrity, continuity and reliability can be improved withthe GNSS option that adds support for Galileo, GLONASS, BeiDou, QZSS and SBAS constellations in addition to the standard GPS constellation. With more satellites in view, timing performance can be improved in challenging environments, such as urban canyons. SyncServer S650s ship with GNSS hardware ready to be enabled with a software license. The S650 is also available without GNSS in theS650i model.More Timing I/O StandardThe base S650 can host two modules. The Timing I/O modules are equipped with eight connectors for timing signal input and output. The standard configuration offers a broad yet fixed selection of signal I/Os that include IRIG B, 10 MHz and 1PPS.FlexPort—The Ultimate in Timing FlexibilityOur unique FlexPort technology efficiently and cost-effectively adds innovative “any signal, any connector” capabilities, eliminating the wasted space inherent with legacy style fixed signal modules.The FlexPort option enables the six output connectors (J3-J8) to output many supported signals (time codes, sine waves, program-mable periods) all configurable in real time through the secure web interface. User-entered, nanosecond caliber phase offsets for each connector output accommodates variable cable lengths. The two input connectors (J1-J2) can support a wide variety of input signal types.This level of timing signal flexibility is unprecedented and can even eliminate the need for additional signal distribution chassis as there is no degradation in the precise quality of the coherent signals.Oscillator Upgrades Improve Holdover Accuracy and Save Valuable TimeThe standard S650 is equipped with a crystal oscillator that keeps the S650 accurate to nanoseconds when tracking GPS. However, if GPS connectivity is lost and the server is placed in holdover, the oscillator begins to drift, impacting timing accuracy. Upgrading the oscillator improves the holdover accuracy significantly. For example, consider the following drift rates for the standard oscillator compared to theOCXO and Rubidium upgrades.The value of the upgraded oscillator is that if the GPS signal is lost, the S650 can continue to provide accurate time and frequency. This provides personnel time to correct the problem with only gradualdegradation or disruption in time synchronization accuracy.SpecificationsGNSS Receiver/Antenna• 72 parallel channel GNSS receiver• GPS time traceable to UTC (USNO)• Static and dynamic operational modes• Acquisition time of 30 seconds (cold start)• Cable length up to 900 feet (275 m).• GNSS option adds Galileo/GLONASS/BeiDou/SBAS/QZSS support in addition to GPSTime Accuracy at 1 PPS Output• Standard: <15 ns RMS to UTC (USNO), typical• OCXO: <15 ns RMS to UTC (USNO)• Rubidium: <15 ns RMS to UTC (USNO)After one day locked to GPS; evaluated over normal environment (test range <±5 °F) defined in GR-2830.Oscillator Aging (Monthly)• Standard: ±1×10–7• OCXO: ±5×10–9• Rubidium: ±1×10–10After one month of continuous operation.Holdover Accuracy (One Day)• Standard: 400 µs• OCXO: 25 µs• Rubidium: <1 µsEvaluated over normal environment (test range <±5 °F) defined in GR-2830 after five days locked to GPS.Frequency Output Accuracy and Stability• <1x10–12 at 1 day, after locked to GPS for 1 dayStandard Network Protocols• NTP v3,4 (RFC 1305/5905/8633), SNTP(RFC4330)• NTP v3,4 Symmetric keys: SHA1/256/512 and MD5• SNMP v2c, v3• SNMP MIB II, Custom MIB, system status via SNMP• DHCP/DHCPv6• HTTPS/SSL* (TLS 1.2/1.3)• SMTP forwarding• SSHv2• Telnet• IPv4/IPv6• Syslog: 1 to 8 servers (RFC 3164/5424)• Key management protocols can be individually disabled• Port 1: Management and Time protocols• Port 2, 3 and 4 (optional 5 and 6): Time protocols only Optional Network Protocols NTP Server Performance• 10,000 NTP requests per second while maintaining accuracy associated with reference time source.**• Stratum 1 through GNSS: overall server time stamp accuracy of5 μs to UTC with 1-sigma variation of 20 μs (typical).

Hardware and Software RequirementsThe hardware and software requirements are listed here:•Hardware: Network interface cards (NICs) with IEEE 1588 support (e.g., Intel® I210)•Software: Windows OS kernel with PTP hardware timestamp support (e.g., Windows 10 Pro 20H2 or later); build 19042 or laterTo check the build number, run winver from the Windows start menu. Confirm that the build version is19042 or later.•Other: One Linux device as PTP Grandmaster and one or more Windows devices as PTP Slaves (Clients) Because Windows only supports the PTP slave (client) in OC mode, we will need another device withLinux OS to be the PTP Grandmaster to perform the time synchronization.Setting Up the Windows PTP Slave (Client) The Windows Time Service (w32tm) is a Windows service that keeps your computer clock accurate. We will be using the AutoSetupWindowsPTP.exe file to configure the w32tm service and apply the PTP function.NOTEContact a Moxa representative for the AutoSetupWindowsPTP.exe file to configure and run the PTPfunction on your computer.To set up the Windows PTP Slave (Client), do the following:1.Run cmd from the Windows start menu and then run the AutoSetupWindowsPTP.exe file.2.Enter the IP for the Linux PTP Grandmaster.3.Enter the IP address for the PTP Slave.4.Wait until the program sets up the configuration for the w32tm service for the PTP function.After the setup process is completed, the Windows Time service will start automatically.5.Restart the device to apply the configuration to the OS.Additional Information•If the program shows the error "This Windows version doesn't support HW PTP", the Windows version is too old to support HW PTP. Install a newer supported version on your device.•If the program shows the error "Invalid device!", the program cannot setup Windows PTP on the device.Note that only Moxa devices are supported.•PTP messages may use the User Datagram Protocol over Internet Protocol (UDP/IP) for transport. The AutoSetupWindowsPTP.exe program will automatically create the firewall rules to allow the PTPSlave to communicate with the time server.Configuring the PTP Grandmaster Message SettingsTo configure the PTP message settings for the Grandmaster and generate a PTP message based on thesettings, do the following:e the follow settings to configure a PTP massage on the Linux PTP Grandmaster device.Delay Mechanism E2ENetwork Transport UDP IPV4Time Stamping HardwareMulticast EnableptpTimescale 12.On the Linux PTP Grandmaster device, run the ptp4l command.ptp4l -E -4 -H -m -i enp2s03.After the ptp4l starts, type the following command to show the configuration settings.sudo pmc -u -b 0 'GET GRANDMASTER_SETTINGS_NP'4.To modify the setting when the ptp4l is running, run the following command:sudo pmc -u -b 0 \ "SET GRANDMASTER_SETTINGS_NP clockClass 248 clockAccuracy0xfe offsetScaledLogVariance 0xffff currentUtcOffset 37 leap61 0 leap59 0currentUtcOffsetValid 0 ptpTimescale 1 timeTraceable 0 frequencyTraceable 0timeSource 0xa0"Checking the PTP Time Sync FunctionAfter the PTP Grandmaster settings are completed, the Windows time service will start automatically andcheck for the PTP message from the PTP Grandmaster.•Using WireShark to check the message information from the specific LAN.a.The PRP Master will generate a "Announce Msg + Sync Msg + Follow_Up Msg + Sync Msg +Follow_Up Msg" at each loop.b.The W32Time service will send a Delay_Req Msg to the PTP master and PTP master will respond witha Delay_Resp Msg for the time sync.•In the Windows Start menu, run cmd as an administrator and enter w32time.exe /query /status/verbose.I f the "Last Sync Error" shows "0 (The command completed successfully)", the time sync wassuccessful.3.Linux PTP Settings Prerequisites1.Install Debian 11.2.Install the linuxptp package.apt updateapt upgradeapt install ssh linuxptp ethtool build-essential3.Disable the systemd time sync daemon service to avoid unexpected operations.systemctl stop systemd-timesyncdsystemctl disable systemd-timesyncdA Simple TopologyDebian linuxptp PackageThe linuxptp is an implementation of the Precision Time Protocol (PTP) for Linux according to the IEEEstandard 1588.

Amulti-port ordinary clock will automatically be configured as a boundary clock. The default is "OC".b.boundary_clock_jbodWhen running as a boundary clock (that is, when more than one network interfaces areconfigured), ptp4l performs a sanity check to ensure that all the ports share the same hardwareclock device. This option allows ptp4l to work as a boundary clock using a bunch of devices thatare not synchronized to each other.

For at least some of the packets comprising encoding clock references, the so-called time utilized packets, the time stamps are equal to these clock references. For each of the other packets, the so-called current packet, the time stamp is obtained from the clock reference of the upstream time utilized packet closest to the current packet, and from a time increment given by the stamping clock between receptions of the upstream packet and of thecurrent packet.申请人:MAETZ, Pascal,RAMBAULT, Claude,LEYENDECKER, Philippe 地址:FR,FR,FR,FR国籍:FR,FR,FR,FR代理机构:BROWAEYS, Jean-Philippe,BERTHIER, Karine更多信息请下载全文后查看。

Publickey date-time notary facility

专利名称:Public/key date-time notary facility发明人:Fischer, Addison M.申请号:EP90305778.4申请日:19900529公开号:EP0422757A3公开日:19921021专利内容由知识产权出版社提供专利附图:摘要:A time notarization apparatus and method is disclosed which uses a secure,microprocessor based hardware platform which performs public kay cryptographic operations to obtain trusted time stamping with a minimum of intervention by third parties. The hardware platform is encapsulated in a secure fashion so that the device'stimestamping mechanism may not be readily tampered with or altered. The hardware platform includes at least one digital clock (4) and a stable, secure storage device (8) to record the private half of a public/private key pair. Coupled to both the digital clock (4) and the storage device (8) is a data processing device (6) which performs public key signature operations in a secure and tamper-proof manner. Only the processing device (6) has access to the secure storage device (8) and its associated private key. The hardware platform also includes input/output means which receives a digital message which is to be digitally signed and timestamped and which outputs the resulting timestamped signature generated by the device. The hadware platform also includes a power source (12), (e.g., an on-board battery) to ensure the accuracy of the device's digital clock (4) and the security of storage data prior to installation or in case of a power failure.申请人:Fischer, Addison M.地址:60 14th Avenue South Naples Florida 33942 US国籍:US代理机构:Kensett, John Hinton更多信息请下载全文后查看。
