电容式接近传感器操作原理说明书
Capacitive Proximity SensorsTheory of OperationCapacitive proximity sensors are similar to inductive proximity sensors. The main difference between the two types is that capacitive proximity sensors produce an electrostatic field instead of an electromagnetic field. Capacitive proximity switches will sense metal as well as nonmetallic materials such as paper, glass, liquids, and cloth.The sensing surface of a capacitive sensor is formed by two concentrically shaped metal electrodes of an unwound capacitor. When an object nears the sensing surface it enters the electrostatic field of the electrodes and changes the capacitance in an oscillator circuit. As a result, the oscillator begins oscillating. The trigger circuit reads the oscillator’s amplitude and when it reaches a specific level the output state of the sensor changes. As the target moves away from the sensor the oscillator’s amplitude decreases, switching the sensor output back to its original state.Standard T arget and Standard targets are specified for each capacitive sensor. The Dielectric Constant standard target is usually defined as metal and/or water.Capacitive sensors depend on the dielectric constant of thetarget. The larger the dielectric number of a material the easier itis to detect. The following graph shows the relationship of thedielectric constant of a target and the sensor’s ability to detectthe material based on the rated sensing distance (S r).The following table shows the dielectric constants of somematerials. If, for example, a capacitive sensor has a ratedsensing distance of 10 mm and the target is alcohol, theeffective sensing distance (S r) is approximately 85% of therated distance, or 8.5 mm.Detection Through Barriers One application for capacitive proximity sensors is leveldetection through a barrier. For example, water has a muchhigher dielectric than plastic. This gives the sensor the ability to“see through” the plastic and detect the water.Shielding All Siemens capacitive sensors are shielded. These sensors willdetect conductive material such as copper, aluminum, orconductive fluids, and nonconductive material such as glass,plastic, cloth, and paper. Shielded sensors can be flushmounted without adversely affecting their sensingcharacteristics. Care must be taken to ensure that this type ofsensor is used in a dry environment. Liquid on the sensingsurface could cause the sensor to operate.Capacitive Proximity Sensor FamilyThe 3RG16 product family identifies the Siemens capacitive proximity sensor. Units are available in DC or AC versions. Electronic controls such as SIMATIC® PLCs or relays can be controlled directly with the DC voltage version. In the case of the AC voltage version the load (contactor relay, solenoid valve) is connected with the sensor in series directly to the AC voltage. Sensors are available with two-, three-, and four-wireoutputs.Capacitive SensorSelection GuideReview 41) A main difference between an inductive proximitysensor and a capacitive proximity sensor is that acapacitive proximity sensor produces an ____________field.2)Capacitive proximity sensors will sense ____________material.3)The larger the ____________ constant of a material theeasier it is for a capacitive proximity sense to detect.4)It is easier for a capacitive proximity sensor to detect____________ than porcelain.a.teflonb.marblec.petroleumd.paper5)The maximum rated sensing distance of a capacitiveproximity sensor is ____________ mm.Ultrasonic Proximity SensorsTheory of OperationUltrasonic proximity sensors use a transducer to send andreceive high frequency sound signals. When a target enters thebeam the sound is reflected back to the switch, causing it toenergize or deenergize the output circuit.Piezoelectric Disk A piezoelectric ceramic disk is mounted in the sensor surface. Itcan transmit and receive high-frequency pulses. A high-frequency voltage is applied to the disk, causing it to vibrate atthe same frequency. The vibrating disk produces high-frequencysound waves. When transmitted pulses strike a sound-reflectingobject, echoes are produced. The duration of the reflected pulseis evaluated at the transducer. When the target enters thepreset operating range, the output of the switch changes state.When the target leaves the preset operating range, the outputreturns to its original state.The emitted pulse is actually a set of 30 pulses at an amplitudeof 200 Kvolts. The echo can be in microvolts.Blind Zone A blind zone exists directly in front of the sensor. Depending onthe sensor the blind zone is from 6 to 80 cm. An object placedin the blind zone will produce an unstable output.Range Definition The time interval between the transmitted signal and the echois directly proportional to the distance between the object andsensor. The operating range can be adjusted in terms of itswidth and position within the sensing range. The upper limit canbe adjusted on all sensors. The lower limit can be adjusted onlywith certain versions. Objects beyond the upper limit do notproduce a change at the output of the sensor. This is known as“blanking out the background” .On some sensors, a blocking range also exists. This is betweenthe lower limit and the blind zone. An object in the blockingrange prevents identification of a target in the operating range.There is a signal output assigned to both the operating rangeand the output range.Radiation Pattern The radiation pattern of an ultrasonic sensor consists of a maincone and several neighboring cones. The approximate angle ofthe main cone is 5°.Free Zones Free zones must be maintained around the sensor to allow forneighboring cones. The following examples show the free arearequired for different situations.Parallel Sensors In the first example, two sonar sensors with the same sensingrange have been mounted parallel to each other. The targets arevertical to the sound cone. The distance between the sensors isdetermined by the sensing range. For example, if the sensingrange of the sensors is 6 cm, they must be located at least15 cm apart.Mutual Interference Mutual interference occurs when sonar devices are mounted inclose proximity to each other and the target is in a position toreflect echoes back to a sensor in the proximity of thetransmitting sensor. In this case, the distance between sensors(X) can be determined through experimentation.Opposing Sensors In the following example, two sonar sensors with the samesensing range have been positioned opposite of each other. Aminimum distance (X) is required between opposing sensors sothat mutual interferance does not occur.Flat and Irregular Sonar sensors mounted next to a flat surface, such as a wall or Shaped Surfaces smooth machine face, require less free area than sensorsmounted next to an irregular shaped surface.Angular Alignment The angle of the target entering the sound cone must also beconsidered. The maximum deviation from the send direction toa flat surface is ±3°.If the angle were greater than 3° the sonic pulses would bereflected away and the sensor would not receive an echo.Liquids and Liquids, such as water, are also limited to an angular alignment Coarse-Grained Materials of 3°. Coarse-grained materials, such as sand, can have anangular deviation as much as 45°. This is because the sound isreflected over a larger angle by coarse-grained materials.Blanking Out Objects An object may be located in the vicinity of the sound cone thatcauses improper operating of the sensor. These objects can beblanked out by using an aperture made of a sound absorbingmaterial such as rock wool. This narrows the sound cone andprevents pulses from reaching the interfering object.Operating Modes Sonar sensors can be setup to operate in several differentmodes: diffuse, reflex, and thru-beam.Diffuse Mode This is the standard mode of operation. Objects, traveling in anydirection into the operating range of the sound cone, will causethe sensor output to switch states. This mode of operation issimilar to a proximity sensor.Reflex Mode The reflex mode uses a reflector located in the preset operatingrange. The operating range is adjusted for the reflector. Thepulses are bounced off the reflector and the echo pulses arereturned to the sensor. When a target blocks the echo pulsesthe output is activated. Typically used in applications where thetarget is not a good sound absorber.Thru-Beam Mode Thru-beam sensors consist of a transmitter, which emitsultrasonic pulses, and a receiver. If the beam between thetransmitter and the receiver is interrupted the output of thereceiver switches state.Environmental Influences Sound travel time can be affected by physical properties of theair. This, in turn, can affect the preset operating distance of thesensor.Review 51)Ultrasonic proximity sensors use high frequency____________ signals to detect the presence of a target.2)The blind zone of an ultrasonic proximity sensor can befrom ____________ - ____________ cm, depending onthe sensor.3)The approximate angle of the main sound cone of anultrasonic proximity sensor is ____________ degrees.4)The free zone between two parallel ultrasonic sensorswith a rated sensing range of 20-130 cm must begreater than ____________ cm.5)The maximum angle of deviation from the senddirection of an ultrasonic sensor to a flat surface is____________ degrees.6)____________ mode is the standard mode of operationfor an ultrasonic sensor.Ultrasonic Proximity Sensor FamilyThe ultrasonic proximity sensor family consists of a Thru-Beamsensor, compact range (M18, Compact Range 0, I, II, and III),and modular (Modular Range II) sensors.Thru-Beam Thru-Beam sensors consist of a transmitter and a receiver. Thetransmitter sends a narrow continuous tone. When a target ispositioned between the transmitter and the receiver the tone isinterrupted, which causes the output of the receiver to changestate. The operating voltage is 20-30 VDC. The switchingfrequency is 200 Hz at 40 cm sensing distance.Thru-Beam Receivers There are two receivers available for the Thru-Beam sensors.Both use a PNP transistor. One receiver provides a normallyopen (NO) contact and the other provides a normally closed(NC) contact.The sensitivity and frequency setting of the Thru-Beam sensorsis a function of the X1 connection on the receiver.The minimum size of a detectable object is a function of thedistance between the transmitter and the receiver. If thedistance between the transmitter and the receiver is less than40 cm and the minimum gap width between two objects is atleast 3 cm, objects of 2 cm or larger will be detected. If thedistance between the sensors is less, even gaps of less than 1mm can be detected. At maximum sensing distance, objectsgreater than 4 cm will be detected, provided the gap betweenobjects is greater than 1 cm.Compact Range 0Compact Range 0 sensors are available with an integrated or anseparate transducer. They are configured with a normally open(NO), normally closed (NC) or analog output. These sensors havea cubic shape (88 x 65 x 30 mm). The sensors operate on 18 -35 VDC and can handle a load up to 100 mA.Depending on the sensor, the sensing range is either 6 - 30 cm(separate transducer) or 20 - 100 cm (integrated transducer).Switching frequencies vary from 5 Hz to 8 Hz. Compact Range0 sensors have background suppression. This means the upperlimit of the sensing range is adjustable with a potentiometer.T argets within the sensing range but beyond the switchingrange of the upper limit will not be detected.Compact Range I Compact Range I sensors are available with a normally open(NO) or a normally closed (NC) contact. They are also availablewith two outputs, one normally open (NO) and one normallyclosed (NC). These sensors have a cylindrical shape (M30 x 150mm). Several versions are available, including a separatetransducer (shown) and a tilting head (not shown). The sensorsoperate on 20 - 30 VDC and can handle a load up to 200 mA.Depending on the sensor the sensing range is either 6 - 30 cm,20 - 130 cm, 40 - 300 cm, or 60 - 600 cm. Switchingfrequencies vary from 1 Hz to 8 Hz. Compact Range I sensorshave background and foreground suppression. This means theupper and lower limits of the sensing range are adjustable withseparate potentiometer. Targets within the sensing range butbeyond the switching range of the upper and lower limits willnot be detected.SONPROG The ultrasonic sensors discussed so far (Thru-Beam, CompactRange 0, and Compact Range I) are either nonadjustable or canbe adjusted manually with potentiometers. SONPROG is acomputer program, unique to Siemens, that is used to adjustCompact Range II, Compact Range III, and Compact RangeM18 sensors.With SONPROG sonar sensors can be matched individually tothe requirements of a particular application. An interface isconnected between the sensor and an RS232 port of acomputer. SONPROG can be used to set the followingparameters:•Beginning and end of switching range•Switching hysteresis•Beginning and end of analog characteristic•End of blind zone•End of sensing range•NO/NC contacts•Potentiometer adjustments on sensors on/offThese values can be printed out and stored in a file. They areimmediately available when needed. When replacing a sensor,for example, the stored parameters can be easily applied to thenew sensor.Compact Range II Compact Range II sensors are similar in appearance to CompactRange I sensors. A major difference is that Compact Range IIsensors can be adjusted manually or with SONPROG. They areavailable with a normally open (NO) or a normally closed (NC)contact. They are also available with two outputs, one normallyopen (NO) and one normally closed (NC). These sensors have acylindrical shape (M30 x 150 mm). Several versions areavailable, including a separate transducer. The sensors operateon 20 - 30 VDC and can handle a load up to 300 mA. CompactRange II sensors can be synchronized to prevent mutualinterference when using multiple sensors in close proximity toeach other.Depending on the sensor the sensing range is either 6 - 30 cm,20 - 130 cm, 40 - 300 cm, or 60 - 600 cm. Switchingfrequencies vary from 1 Hz to 8 Hz. Compact Range II sensorshave background and foreground suppression.Compact Range II An analog version of the Compact Range II sensor is available. Analog Version The analog measurement is converted by the sensor to digitalpulses. A counter in LOGO! or a PLC counts the pulses andmakes the measurement conversion. If, for example, theswitching output of the sensor were set such that 50 Hz wasequivalent to 50 cm and the gate time of LOGO! was set for 1second, LOGO! would be able to accurately convert anyfrequency to its corresponding distance.Compact Range III Like the Compact Range II sensors, Compact Range III sensorscan be adjusted manually or with SONPROG. They are availablewith a normally open (NO) or a normally closed (NC) contact.They are also available with two analog outputs, 0 - 20 mA or 0 -10 VDC. The sensors operate on 20 - 30 VDC and can handle aload up to 300 mA. Compact Range III sensors can besynchronized to prevent mutual interference when usingmultiple sensors in close proximity to each other. In addition,they offer an arithmetic mean feature. This is useful for liquidlevel sensing or other applications where reflection variationscan occur. The arithmetic mean feature helps compensate forthese variations.Depending on the sensor, the sensing range is either 6 - 30 cm,20 - 130 cm, 40 - 300 cm, 60 - 600 cm, or 80 - 1000 cm.Switching frequencies vary from 0.5 Hz to 5 Hz. CompactRange III sensors have background and foreground suppression.Compact Range M18The small size (M18 x 101 mm) of the Compact Range M18sensor makes it suited for applications where space is limited.Compact Range M18 sensors are available with a normallyopen (NO) or a normally closed (NC) contact. They are alsoavailable with an analog output (4 - 20 mA, 0 - 20 mA, or 0 - 10VDC). The sensors operate on 20 - 30 VDC and can handle aload up to 100 mA.Depending on the sensor the sensing range is either 5 - 30 cmor 15 - 100 cm and the switching frequency is either 4 or 5 Hz.Compact Range M18 sensors have background suppression.Compact Range with Siemens also manufactures ultrasonic sensors for use with for use with AS-i AS-i. Four sensing ranges are available: 6 - 30 cm, 20 - 130 cm,40 - 300 cm, and 60 - 600 cm. The switching frequency variesfrom 1 to 8 Hz.Modular Range II The next group of ultrasonic sensors is Modular Range II. The and the Signal Evaluator Modular Range II consists of sensors and their correspondingsignal evaluator. The signal evaluator is required for ModularRange II sensors. Sensor values are set using buttons on theevaluator. A two-line LCD displays the set values.The signal evaluator can operate a maximum of two ModularRange II sensors. It is supplied with a 20 - 30 VDC powersupply. It has two switching outputs, one error output, and oneanalog output.Modular Range II Sensors Module Range II sensors are available in three versions: cubicsensors, cylindrical sensors, and spherical sensors. They haveanalog and normally open (NO) or normally closed (NC) outputs.As mentioned earlier, all settings and operations are done with asignal evaluator.Depending on the sensor the sensing range is either 6 - 30 cm,20 - 130 cm, 40 - 300 cm, 60 - 600 cm, or 80 - 1000 cm.Switching frequencies vary from 1 Hz to 20 Hz. Modular RangeII sensors have background and foreground suppression.Accessories An adjusting device with a mounting flange (shown) or bracket(not shown) and a 90° diverting reflector are available for M30spherical sensors. The adjusting device allows the sensor to bepositioned in hard-to-mount areas.Review 61)Ultrasonic ____________-____________ proximitysensors require a separate transmitter and receiver.2)If X1 is connected to L+ of a Thru-Beam ultrasonicproximity sensor, the sensing range is ____________ to____________ cm.3)The maximum sensing range of a Compact Range 0ultrasonic sensor with a ____________ transducer is6 - 30 cm.4)Compact Range ____________ does not offerforeground suppression.a.0b.Ic.IId.III5)____________ is a computer program used to adjustCompact Range II, Compact Range III, and CompactRange M18 ultrasonic sensors.6)____________ Range II require a signal evaluator.7) A signal evaluator can operate a maximum of____________ sensors.a.1b.2c.3d.4。

unsigned int average; unsigned int raw; unsigned int trip;
变量 average 存放前面 16 个采样值的滑动平均值; raw 是从 Timer1 读取的当前传感器数据;而 trip 则是按钮按 下时频率与平均值的差。最简单的检测按钮是否按下的 算法就是测试 raw 是否比平均值还要小某个固定值,其 代码示例如下。

Power and Operation4.1 Power SelectionThe CPT213B Capacitive Sense Evaluation Board is designed to be powered by two different sources:•Through the on-board USB.•Through the EXP header.The figure shows how the different power sources are connected to the device.Figure 4.1. CPT213B SLEXP8019A Power SupplyWhen the USB is connected, the board is powered from the LDO internal to the USB device, which is in turn powered by the USB cable.The board can also be powered externally through the VMCU and GND pins of the expansion header when the board is attached to a power supply or an EFM MCU Starter Kit.When power is provided through the USB or an external power supply, the device can act as a stand alone device. When it is connec-ted to an EFM MCU Starter Kit through the expansion header, the device acts as a peripheral to the MCU by providing capacitive sense capabilities.4.2 StandaloneIn standalone mode, the CPT213B SLEXP8019A on the CPT213B Capacitive Sense Evaluation Board is designed to showcase and test the board's features or act as a breakout board for any application. To operate in this mode, apply power using the USB connector or an external supply.The board can operate on its own to demonstrate and test the board's touch features and functionalities. The CPT213B SLEXP8019A features configurable options such as touch characteristics, output characteristics, and user feedback peripherals. The device's fea-tures can be configured in Simplicity Studio using [Xpress Configurator ], and the capacitive sense data can be viewed in the [Capaci-tive Sense Profiler ].The touch qualification engine on the device will process the touch information and output the results through I2C. The device outputs can be accessed through the expansion header, and the capacitive sense inputs can be accessed through the vias on the board.No tR e co mme nd edn s4.3 Connected to the Expansion HeaderThe CPT213B Capacitive Sense Evaluation Board is designed to quickly attach to any EFM32 and EFM8 MCU starter kit and jump-start the development of capacitive sense capable applications. Attach the CPT213B Capacitive Sense Evaluation Board to the STK through the expansion header to connect the power and communication pins.To see how the board works in conjunction with the MCU starter kit, go to the starter kit's [Demos ] under [Getting Started ] in Simplicity Studio and run [CPT213B Demo ].For more details on the starter kit, see the corresponding starter kit's user guide.Note: Not all EFM32 starter kits support this expansion board. See the available demos in Simplicity Studio for more information.Figure 4.2. CPT213B SLEXP8019A Connected to an Example EFM8BB2 STKNo tR e co mme nd edf or N e wDe si g n s5. PeripheralsThe starter kit has a set of peripherals that showcase some of the features of the CPT213B device.Be aware that some CPT213B I/O routed to peripherals are also routed to the breakout pads. This must be taken into consideration when using the breakout pads for your application.5.1 Capacitive Sense Touch PadsThe kit has 13 capacitive sense touch pads. The touch pads are connected in order to pins CS00 - CS12 of the CPT213B SLEXP8019A. After the touch pad inputs have been processed by the touch qualification engine, the CPT213B SLEXP8019A will out-put the result through I2C.The capacitive sense inputs can be configured for different thresholds, debounce counter values, scan periods, gain, scanning meth-ods, touch time-outs, and touch exclusiveness using the [Xpress Configurator ] in Simplicity Studio. The device outputs can also be configured for different pin polarities and drive strength.See the CPT213B SLEXP8019A Data Sheet for more detailed information on the different configurations.CPT213B DeviceFigure 5.1. Capacitive Sense Touch PadsNo tR e co mme nd ee si g n s6. Connectors6.1 Test PointsThe test points located on the left of the touch pads are routed to the capacitive sense input traces and power rails.The capacitive sense input traces can be accessed through the vertically aligned vias located in middle of the board on the left of the touch pads. All 13 CPT213B capacitive sensing touch pads are bound to each via.At the bottom left corner of the board, there are two test points for VMCU labeled "ST1" to measure the active current of the board using an in-circuit ammeter. A 2.54 mm pitch pin header can be soldered in for easy access to these pins.Note: In order for the capacitive sense pins to be connected properly to your application or power to be measured correctly, the 0 ohm resistors must be removed. The 0 ohm resistor for a channel can be found next to the corresponding via on the top side of the board.At the top left corner of the board, there are three test points for Config Clk, Config Data, and GND to allow programming of external CPT devices.CS00CS01CS02CS03CS04CS05CS06CS07CS08CS09CS10CS11CS12Figure 6.1.
