LX G858系列LORA 无线远传水表一:概括1、公司介绍人民电器集团仪器仪表有限公司生产的Lora无线远传水表是针对日常用水的实际需要,自行研制的一款便于远程抄表及控制的水表。
实现水表用水量的远程直读,有效的避免了管理部门上门抄表。
方便管理部门对Lora无线远传阀控水表的用水情况进行控制,使得远程抄表及控制变得更快捷、可靠、在节约人力、物力和财力的同时,有效地提高生产力。
2、结构原理(1)Lora无线远传水表是按照国家标准GB/T778.1~3-1996《冷水水表》、CJ/T224-2012标准设计制造的预收费水表,无线远传水表其实就是以湿式水表为计量基表,加装具有远传发讯输出计量数据的模块装置,接收无线抄表主设备的抄表指令发射数据。
(2)LoRa模块,通常实现的就是物理层的通信,目前,LoRa主要在全球免费频段运行,包括433、868、915MHz等,LoRa技术具有远距离、低功耗(电池寿命长)、多节点、低成本的特性,Lora无线远传水表由无线通讯模块和基表组成,具有计量、运算、存储、诊断、无线远传等功能。
3、无线远传LORA水表的计量方式采用双干簧管检测方式,有效避免了电磁干扰和脉冲抖动带来的误差。
水表盘上独特的翻盖设计,避免了灰尘累积看不清楚表盘的问题;它的通讯方式是:通讯模块平时处于休眠状态,每秒钟醒来一次很短的时间,在此时间内侦听是否存在无线指令。
若有,则启动接收功能进行接收数据;若无,则继续进入睡眠状态。
此方法极大的降低了模块的平均功耗,有效的延长了电池的使用寿命。
水司只需像安装普通表一样安装好无线远传智能水表,抄表人员只需在办公室操作后台软件就可以抄取整个城市的水表数据以及远程控阀,且远程抄表系统每天自动抄表一次,实时掌握每户水表的当前数据、历史数据,居民水表集中的小区最适用这种远程抄表方式二、产品介绍1:产品外形图2:产品的口径参数图如下:公称口径DN长度L 高度H螺纹D连接螺纹长度mmmmmm amin bmin 15175100G3/4B 101220195100G18121425205100G1/4B 141632225100G11/2B1618三、产品的技术参数1、产品技术参数介绍(1)工作环境:温度0.1℃至+45℃(冷水)、0.1℃至90℃(热水)湿度:0至95%RH,通讯2400bps(2)表到数据采集器最大距离:≤1000m (3)通讯规约:Lora 扩频无线通讯、自组网(4)采集器正常带载水表为800块水表(5)采集器采用4G移动网络信号传输稳定快速,无需集中器。

When there is water between the two metal probes, LWL02 indicates a water leak event and uplink to IoT server via LoRaWAN network.LWL02 is powered by 2 x AAA batteries and target for long time use, these two batteries can provide about 16,000 ~ 70,000 uplink packets, which result in 2 ~ 10 years battery life. After battery running out, user can easily open the enclosure and replace with 2 common AAA batteries.The LWL02 will send periodically data every day as well as for each water leak event. It also counts the water leak times and calculate last water leak duration. User can also disable the uplink for each water leak event, instead, device can count each event and uplink periodically.Each LWL02 is pre-load with a set of unique keys for LoRaWAN registration, register these keys to LoRaWAN server and it will auto connect after power on.1.2Features✓LoRaWAN Class A v1.0.3✓Frequency Bands: CN470/EU433/KR920/US915/EU868/AS923/AU915/IN865/RU864 ✓SX1262 LoRa Core✓Water Leak detect✓ 2 x AAA LR03 Batteries✓AT Commands to change parameters✓Uplink on periodically and open/close action✓Remote configure parameters via LoRa Downlink✓Firmware upgradable via program port1.3Applications✓Smart Buildings & Home Automation✓Logistics and Supply Chain Management✓Smart Metering✓Smart Agriculture✓Smart Cities✓Smart Factory1.4Dimension1.5Firmware Change logLWL02 use the same firmware as LDS01.LWL02 Image files – Download link2.Power ON LWL02When receive the LWL02, please open the enclosure and add 2 x AAA batteries to power it.

Introduction1.1 What is LoRaWAN 4-Channels Distance SensorThe Dragino LDDS04 is a LoRaWAN 4-Channels Distance Sensor for Internet of Things solution. It is capable to add up to four Ultrasonic Sensors to measure four distances at the same time.The LDDS04 can be applied to scenarios such as horizontal distance measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewer, etc.It detects the distance between the measured object and the sensor, and uploads the value via wireless to LoRaWAN IoT Server.The LoRa wireless technology used in LDDS04 allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.LDDS04 is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.Each LDDS04 is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.1.2 Features•LoRaWAN 1.0.3 Class A•Ultra-low power consumption•Detect Range: Base on External Probe•Monitor Battery Level•Bands: CN470/EU433/KR920/US915/EU868/AS923/AU915/IN865•AT Commands to change parameters•Uplink on periodically•Downlink to change configure•8500mAh Battery for long term use1.3 Applications•Horizontal distance measurement•Parking management system•Object proximity and presence detection•Intelligent trash can management system•Robot obstacle avoidance•Automatic control•Sewer1.4 Pin mapping and power on1.5 Probe Options1.5.2 P01A-15 probeA01A-15 is mainly used for plane distance measurement; it can carry out targeted measurement on plane objects and can measure long distances and high accuracy.Beam Chart:(1) The tested object is a white cylindrical tube made of PVC, with a height of 100cm and a diameter of7.5cm.(2)The object to be tested is a "corrugated cardboard box" perpendicular to the central axis of 0 °, and the length * width is 60cm * 50cm.Mechanical:Application:1.5.3 A02-15 probeBeam Chart:(1) The tested object is a white cylindrical tube made of PVC, with a height of 100cm and a diameter of 7.5cm.(2)The object to be tested is a "corrugated cardboard box" perpendicular to the central axis of 0 °, and the length * width is 60cm * 50cm.Mechanical:Application:1.5.4 A13-15 probeBeam Chart:(1) The tested object is a white cylindrical tube made of PVC, with a height of 100cm and a diameter of 7.5cm.(2)The object to be tested is a "corrugated cardboard box" perpendicular to the central axis of 0 °, and the length * width is 60cm * 50cm.Mechanical:Installation Requirement:Application:1.5.5 A13-16 probeBeam Chart:(1) The tested object is a white cylindrical tube made of PVC, with a height of 100cm and a diameter of 7.5cm.(2)The object to be tested is a "corrugated cardboard box" perpendicular to the central axis of 0 °, and the length * width is 60cm * 50cm.Mechanical:Application:2. Configure LDDS04 to connect to LoRaWAN network2.1 How it worksThe LDDS04 is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and power on the LDDS04. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.2.2 Connect ProbeLDDS04 has a converter, User need to connect the Ultrasonic Probes to the convert as below. Different probes aresupported, please see this link for the probe options.Probe mapping as below.2.3 Quick guide to connect to LoRaWAN server (OTAA)Following is an example for how to join the TTN v3 LoRaWAN Network. Below is the network structure; we use theLG308 as a LoRaWAN gateway in this example.The LG308 is already set to connected to TTN network , so what we need to now is configure the TTN server.Step 1: Create a device in TTN with the OTAA keys from LDDS04.Each LDDS04 is shipped with a sticker with the default device keys, user can find this sticker in the box. it looks like below:You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:Register the device:Add APP EUI and DEV EUI:Add APP EUI in the application:Add APP KEYPut a Jumper on JP2 to power on the device. ( The Switch must be in FLASH position).Step 3: The LDDS04 will auto join to the TTN network. After join success, it will start to upload messages to TTN and you can see the messages in the panel.2.4 Uplink PayloadLDDS04 will uplink payload via LoRaWAN with below payload format:Uplink payload includes in total 11 bytes.2.4.1 Battery InfoCheck the battery voltage for LDDS45.Ex1: 0x0B45 = 2885mVEx2: 0x0B49 = 2889mV2.4.2 Interrupt PinThis data field shows if this packet is generated by interrupt or not. Click here for the hardware and software set up. Note: The Internet Pin is a separate pin in the screw terminal. See pin mapping.Example:(0x0D4A & 0x8000) >>15 = 0: Normal uplink packet.(0x8D41 & 0x8000) >>15 = 1: Interrupt Uplink Packet.2.4.3 DistanceThe measuring distance of the four distance measuring modules, the default unit is cm.Example:Uplink Payload: 0D 4A 03 16 03 18 03 1A 03 15 01Data analysis:Distance of UT sensor1 : 0316(H) = 790 (D)/10 = 79cm.Distance of UT sensor2 : 0318(H) = 792 (D)/10 = 79.2cm.Distance of UT sensor3 : 031A(H) = 794 (D)/10 = 79.4cm.Distance of UT sensor4 : 0315(H) = 789 (D)/10 = 78.9cm.2.4.4 Message TypeFor a normal uplink payload, the message type is always 0x01.Valid Message Type:2.4.5 Decode payload in The Things NetworkWhile using TTN network, you can add the payload format to decode the payload.The payload decoder function for TTN is here:LDDS04 TTN Payload Decoder: ttps:///dragino/dragino-end-node-decoderfunction Decoder(bytes, port) {var decode = {};var value=(bytes[0]<<8 | bytes[1]) & 0x3FFF;decode.BatV= value/1000;decode.EXTI_Trigger=(bytes[0] & 0x80)?

AUR°EL S.p.A. non si assume la responsabilità di danni causati dall’uso improprio del dispositivo.-------------------------------------------------------------------------------------------------------------------------------------------------------------------If "without retry mode" is enabled on the encoder (this mode is always active on XTR-8LR-4ZN and it is active on XTR-8LR-ENC if pin 18 RETRY EN is low), it sends packets until at least one input is active therefore XTR-8LR-DEC sends the ACK packet only when all inputs of the encoder are released.If "with retry mode" is active on the encoder (this mode is not available for the XTR-8LR-4ZN and it is active on XTR-8LR-ENC if pin 18 RETRY EN is high), it sends only one packet (even if inputs remain active) therefore XTR-8LR-DEC sends the ACK packet immediately after the reception of a valid packet from the encoder.Automatic learning procedurePushing and releasing the LEARN button located on the module, it enters into learning procedure.LED blinks quickly for 10 seconds: during this time, every activation of a input on an encoder will be learned from the decoder. The positive learning of the encoder will be indicated from a switching on of the LED for 1 second. If a same encoder will be learned LED will switching on for 0,5 second.With the automatic learning procedure all inputs available on the encoder have been associated to the outputs (monostable) of the decoder.For the learning of a new encoder,repeat this procedure.If no encoders will be recognized in the 10 seconds learning time, the module will leave the learning procedure.Manual learning procedurePushing and releasing the LEARN button located on the module, it enters into learning procedure.LED blinks quickly for 10 seconds. Push again LEARN button in this time: LED will switch on permanently. Push again LEARN button for the selection of OUT1 output ( LED will blink one time for confirmation ), push again the LEARN button for the selection of OUT2 ( LED will blink twice ) and so on,up to the desired output.Once it has been identified the desired output,activate the input of the encoder to match, then LED will blinks a number of time correspondent to the number of the output.The output, after this learning, is monostable.Repeat the same procedure for the learning of a new encoder or a new input of the same encoder.---------------------------------------------------------------------------------------------------------------------------------------------------------------------User manualLe caratteristiche tecniche possono subire variazi oni senza preavviso. AUR°EL S.p.A. non si assume la responsabilità di danni causati dall’uso improprio del dispositivo.-------------------------------------------------------------------------------------------------------------------------------------------------------------------Monostable or bistable settingIn order to select the OUT1-4 outputs modes, set the SET1-2 inputs following the chart below:SET 1SET 2OUT1OUT2OUT3OUT4HIGH HIGH MONO MONO MONO MONO HIGH LOW MONOMONOBI BI LOW HIGH MONO 1/2 sec MONO 1/2 sec BI BI LOWLOWBIBIBIBIMONO = monostable output:output is active until the input on the encoder is active.BI = bistable output:each activation of the input on the encoder changes the output status.MONO 1/ 2 Sec = monostable output:output is active per1/2 second from when input has been released on the encoder side.The output setting is detect only at the power on therefore for any changes of the setting it is necessary to switch off the decoder, modify SET1 and SET2 and power on again the device.NOTES on MONOSTABLE OUTPUT:∙if only one input is active on the encoder, the related output on the decoder is active until the input is active on encoder side;∙if two or more inputs are active on the encoder, it transmits packets with the information of the inputs status but the decoder disables all outputs.NOTES on BISTABLE OUTPUT:∙the output state changes when the decoder receives a packet from the encoder with the information of input active and a counter greater than the last received. Therefore, in case of input active for a long time on the encoder, the output will have only a status change because,as described in encoder user manual,the counter isn't increased. The output changes status if the input on the encoder is disabled and a new activation is done;∙if two or more inputs are active on the encoder, it sends this information and the related output status changes. For example, if IN1 is active then OUT1 will be active on the decoder. If now IN2 is activated,maintaining IN1 active, the encoder sends the information of IN1and IN2 active and it increases the counter value. Therefore the decoder disables OUT1 and enables OUT2.Memory erasing procedurePushing and releasing the LEARN button located on the module, it enters into learning procedure.LED blinks quickly for 10 seconds: during this time push again the button for around 5 seconds, when LED stops to blink, afterwards release the button and check the 5 blinks of LED to show the occurred memory erasing.After device reset no encoder will be recognized and all outputs will be set according to the selected mode with SET1 and SET2 lines.---------------------------------------------------------------------------------------------------------------------------------------------------------------------User manualLe caratteristiche tecniche possono subire variazi oni senza preavviso.

XTR-8LR-DEC must be supplied from very low voltage safety source protected against the short circuits.maximum voltage variations allowed:2.1 ÷3.6 V. However it is preferable to maintain a stable voltage to a predetermined value in the range of voltage as specified above, using a "fast transient response"voltage regulator.2. Decoupling, close to the transceiver, with a ceramic capacitor of minimum 100nF.3. Connect electrolytic capacitor 100uF, low ESR, close to pins 5,14 (VDD).Input pin interface:Put 100pF capacitors close to the corresponding input pins, connected between them and the ground plane.Ground:The ground must surround at the best the welding area of the module and must also be realized in the lower face of the PCB in order to obtain the optimal result, with the through holes connecting the two ground planes.Antenna:Connect pin 1(antenna) to the coaxial connector or antenna, with 50 ohm constant impedance microstrip;width 3.2 mm for PCB with thickness 1.6 mm and width 1.6 mm for PCB with thickness 1mm.The antenna is a typical rigid copper wire (insulated or not) of 8cm length and cross-section at least of 0.5mm²placed vertically to the ground plane.Other placements of antenna (bend, coil) will work but performance are not predictable.As an alternative to connect the module to an external antenna, connect an SMA connector into PCB using 50 ohm microstrip.---------------------------------------------------------------------------------------------------------------------------------------------------------------------User manualLe caratteristiche tecniche possono subire variazi oni senza preavviso.

Input frequencies can range from 0.005 Hz to 1 MHz.Arithmetic functions A+B, A-B, AxB, A/B or A/B-1 are made available by the Extended counter main board and can track the sum, difference, product, ratio, or draw of both input channels. These functions can be applied to scaled rates, scaled totals, square root of rates, totals after square root extraction, custom curve linearized rates, or totals after custom curve linearization. •Sum A+B can be used to add two flows for total flow, or to add the number of parts carried by two conveyor belts.•Difference A-B can be used to subtract outflow from inflow for net flow, or to subtract reject parts from total parts. •Product AxB can be used to multiply two rates, for example to compute horsepower by multiplying torque by RPM. •Ratio A/B can be used to compare flow rates in two channels, the RPM of rollers or gears, or the speed of moving machinery such as conveyor belts. Ratio can also be applied to scaled totals to compare two batches to be mixed. In this application, one transmitter is used to monitor the ratio of flow rates, and a second transmitter to monitor the resulting batch totals.•Draw A/B-1 is obtained by subtracting 1 from ratio. Draw is used to measure the elongation of material as it passesbetween rollers, or to monitor variation in the speed of rollers for tensioning.Exceptional Accuracy and Stability. Laureate pulse input frequency and rate transmitters determine frequency by taking the inverse of period as measured with a calibrated quartz crystal time base. Extremely accurate 6-digit internal readings (±999,999 counts) are processed in software. The update rate of the transmitter output is a programmed gate time + 30 ms + 0-2 signal periods. For pulse rates of 60 Hz and above, the update rate would be 20 per second. Such fast update rates are ideal for alarm and control.Standard features of Laureate LTE transmitters include:•Ethernet I/O, isolated. Supported protocols are ModbusRTU and ASCII (tunneled via Modbus TCP) and Laurel ASCII.The latter is simpler than the Modbus protocol and is recom-mended when all devices are Laureates. Note that RS232 or RS485 data I/O in lieu of Ethernet is provided by our LT Series transmitters.•4-20 mA, 0-20 mA or 0-10V analog transmitter output, isolated, jumper-selectable and user scalable. All selections provide 16-bit (0.0015%) resolution of output span and 0.02% output accuracy of a reading from -99,999 to +99,999 counts that is also transmitted digitally. Output isolation from signal and power grounds eliminates potential ground loop problems.The supply can drive 20 mA into a 500 ohm (or lower) load for 10V compliance, or 10V into a 5K ohm (or higher) load for2 mA compliance.•Dual solid state relays, isolated. Available for local alarm or control. Rated 120 mA at 130 Vac or 180 Vdc.•Transducer excitation output, isolated. User selectable 5V@100 mA, 10V@120 mA or 24V@50 mA. •Universal 85-264 Vac power. Low-voltage 10-48 Vdc or 12-32 Vac power is optional.Discovery and configuration of Laureate Ethernet Nodes is easily achieved with Laurel's Node Manager Software, and the discovered transmitters can then be programmed using Laurel's Instrument Setup Software. Both softwares run on a PC under MS Windows and can be downloaded at no charge.SpecificationsPulse InputSignal Types GroundingChannel A Frequency Channel B Frequency Minimum Signal Maximum Signal Noise FilterContact Debounce Time Base Accuracy Arithmetic Functions AC, pulses from NPN, PNP transistors, contact closures, magnetic pickups.

The sensing element is normally a turbine flow meter, which outputs pulses at afrequency proportional to flow rate. The A/B ratio can also be transmitted for totalized rate (or delivered volume).Comparing Fluid Inflow & OutflowThe ratio of the inflow and outflow rates of a tank is a measure of the relative filling or emptying rate. The same transmitter can also be programmed to transmit the net inflow or outflow rate in flow units, or to transmit totalized inflow our outflow in volume units. Any of these parameters can be alarmed using the dual relay board and be transmitted as a 4-20 mA current loop and as serial data.Controlling Coating Thickness on a FilmIn this application, Channel A measures the rate at which a coating material is applied, as measured by a flow meter, while Channel B measures the speed of the film based on pulses from a proximity switch. Transmitting and alarming the A/B ratio assures that an even thickness of coating material is applied as the speed of the film is varies.Instrumenting a Pulsed Laser SystemThe dual-channel Laureate transmitter can measure the speed of conveyor lines by using the output of proximity switches which sense gear teeth or spokes of rotating drive wheels. Transmitting the speed ratio of two lines allows line speeds to be adjusted so that material arrives at work stations when needed.Measuring Draw for ElongationDraw (Ch A / Ch B - 1) can be used to indicate the elongation of films compressed between rollers, the shrinkage films, and the RPM difference of rollers whose speed is varied to main-tain tension. The high resolution of Laureate dual channel transmitters is ideal for comparison of rates that are close to each other.Ordering GuideCreate a model a model number in this format: LTE80FR, CBL04Transmitter Type LTE Laureate Ethernet & 4-20 mA TransmitterMain Board 8 Extended Main Board (required for arithmetic functions) Power 0 Isolated 85-264 Vac or 90-300 Vdc 1 Isolated 12-32 Vac or 10-48 Vdc Input TypeFR Dual-Channel Frequency。
