DSP-222 检测器传感器单元使用手册说明书

DSP-222 Operations ManualDual Channel InductiveLoop Detector Sensor UnitThis manual contains technical information for the DSP-222 detector sensor unit. Included are general description, general characteristics, installation procedure, adjustment instructions, operational guide, maintenance procedures and technical schematics and drawings.1. General DescriptionThe DSP-222 is a dual-channel inductive loop vehicle detector sensor unit designed to meet the State of California, Department of Transportation, (Caltrans) specification TSCES dated January of 1989 and the addendum dated July of 1991.2. General CharacteristicsThe sensor unit incorporates a double-sided 44-pin edge connector for the connection of power, loop inputs and call outputs and sensor unit reset. Each channel has individual front-panel controls for setting sensitivity, frequency, and pulse/presence mode. Each channel is also equipped with two high-intensity front-panel LEDs which are used to indicate the detect state and fail condition of the individual channels. Call outputs are optically isolated solid-state transistors. The sensor unit occupies one position of a standard 170 input file. Each channel of the DSP-222 will automatically tune to any loop and lead-in inductance between 50 and 750 microhenries with a loop system “Q” as low as 5. The unit will detect inductance changes as small as 0.01%L/L.3. Installation and AdjustmentsThe sensor unit is factory shipped with all switches set to off signifying both channels are disabled. The MIN PRESENCE jumper J1 located on the printed circuit board is installed forcing all detection outputs to last a minimum of 100 ms in the presence mode. The ALTERNATE jumper J2 located on the printed circuit board is installed forcing both channels to operate in the non-scanning mode.a) Remove the MIN PRESENCE jumper J1 on the circuit board to allow presence outputs of times less than 100 ms, if so desired.b) Remove the ALTERNATE jumper J2 on the circuit board to allow both channels to scan sequentially, if so desired.c) Make sure that the sensor unit is firmly seated into its position in the input file.d) Set the PULSE switch on for pulse operation. Set the PULSE switch off for presence operation.e) Adjust sensitivity by setting switches S1, S2, and S4 to the desired position using standard binary coding. Sensitivity 1 is the lowest setting and Sensitivity 7 is the highestsetting. If a channel is not used, it may be switched off (disabled) by setting it to Sensitivity 0 (all three switches off).f) Frequency setting needs to be changed only if crosstalk occurs between nearby loops. Crosstalk usually manifests itself as chattering of the call output. Change the frequency if crosstalk is encountered. Four frequency positions are available on each channel to assist in alleviating interference. It may be necessary to reset the channel after the frequency has been changed.g) Check the front-panel indicators. If the Fault LEDs on either channel are flashing there is a problem with the loop system on that channel. Observe the flash sequence to determine the type of fault. A single flash followed by a pause indicates an open loop system. A double flash indicates a shorted loop system. Check the loop connections carefully. Reset both channels by momentarily selecting a different sensitivity or mode and then return to the original setting.h) Monitor operation and make adjustments to the sensitivity and frequency as necessary.4. Theory of OperationThe DSP-222 works on the principle that loop frequency is directly related to loop inductance. However, the change in loop frequency is very small -- perhaps as little as one hertz. It is easy to measure a change of one hertz simply by counting the number of cycles in one second. Unfortunately, the minimum response time using this method is easily greater than one second. To improve the response time, the measurement is done by gating a high-speed stable oscillator with the loop frequency. This scheme, called period measurement, provides high-resolution in a short period of time. This measurement is compared to a previously established reference to determine whether or not the frequency of the loop oscillator has changed sufficiently to indicate the presence of a vehicle.The high speed of the reference crystal oscillator ensures that the sample can be taken within a very short period of time. For example, at sensitivities less than 4, a sample can be taken within 2 ms which allows the sensor unit to respond to a vehicle presence (or loss of presence) in the detection area with an accuracy of 1 ms. Note: This is true only if the ALTERNATE jumper J2 is installed.Sensitivity is a function of how long a sample is used for the determination of a vehicle presence, i.e. the longer the sample time, the more sensitive the sample. Since the sensor unit measures the minute changes in loop oscillations, it follows that low frequency loops are innately more sensitive than high frequency loops. In order to keepthe sensitivity the same over the wide spectrum of loop frequencies, the sensor unit first measures the loop frequency and calculates the number of complete cycles needed for a sample. This value is then used for all subsequent loop measurements for this channel.The sensor unit checks the completed sample to confirm that it is still within acceptable operating limits and then determines whether the sample has changed sufficiently with respect to the stored reference to indicate the presence of a vehicle. It then controls the output and indicators appropriately. Minor changes in period occurring over a relatively long time are due entirely to environmental fluctuations. By altering the stored reference slowly, these environmental changes are ignored. In this fashion, the sensor unit can compensate for temperature changes and other long-term effects such as water on the pavement.5. Detailed Description of Circuit OperationThe following description is valid for both channels of the DSP-222. Reference designators are shown for channel 1 with those related to channel 2 in parentheses. Refer to section 8 for block diagram and schematic.The loop oscillators consist of two PNP transistors in a basic Franklin type circuit. Q1 (Q4) is coupled to Q2 (Q5) to form the active oscillator. The loop is connected to the oscillator circuit with the isolation transformer T1 (T2). The reflected roadway loop inductance is resonated with the capacitor C5 (C11). Frequency modification capacitors C3 (C9) and C4 (C10) are switched in via SW1 (SW2) and are used to change the operating frequency of the loop circuit. Neon surge arrestor I1 (I2) provides high voltage spike protection. When loops are connected to the oscillators and the unit is under power, the oscillators will resonate at their natural frequency according to the inductance of the roadway loop and the capacitance described above.Surge protective diode D1 (D2) is used to limit voltage surges that may appear on the circuit side of the loop transformer. The output signal from the oscillator is present on the collector of Q1 (Q4) and is a sine wave at the oscillator frequency.The loop frequency signals from the oscillators are routed to the squaring circuits formed by transistor Q3 (Q6). The outputs of the squaring circuits are passed through a low-pass filter network consisting of resistor R9 (R18) and capacitor C6 (C12). From here, the square wave loop frequency is presented to the capture register input of the microprocessor.The Microchip PIC 16F73 U1 is an advanced RISC microcontroller using Harvard architecture. The processor is being clocked with a 20 MHz crystal. This speed insures fast instruction processing as well as a high-speed time base for the two independent capture registers used in the period measurement of the loop frequencies.The front-panel LED indication LED2 (LED1) is used to indicate the “Call” output of the channels. LED3 (LED4) indicates the “Fail” condition of the loops. These outputs are driven directly by the microcontroller. Monolithic voltage regulators provide a stable 12-volt reference supply U3. Two additional 5-volt regulators provide stable 5-volt power to the digital circuitry U2 and loop oscillators respectively U4.An external reset signal is provided to reset the microcontroller with a low (ground true) signal on pin C of the loop sensor unit. This is accomplished by using Q9 as an input voltage comparator and phase inverter as well as a second phase inverter Q10. The input signal is “noise” filtered with C15 and diode D5.Front-panel switch S1 (S2) is used to input data to the microcontroller from the user. The sensitivity setting and the choice of pulse or presence operation are routed directly to the input ports of the microcontroller U1.Transistor Q7 (Q8) is the high-current driver necessary to power the opto-isolator U5 outputs for external equipment.The +24 volt input is protected with a power diode D6 to prevent damage to the unit if power is connected incorrectly. In addition, an input resistor R36 is provided to reduce inrush current when the unit is plugged into a “hot” card cage. The input voltage is well filtered with C16.6. Preventive MaintenanceOver the years, the electronic components used in inductive loop detectors have become very reliable. Generally, most inductive loop sensor problems can be traced to the loop system. The loop system is defined as the loop of wire(s) located in the street, the lead-in wire(s) located between the street loop and the controller cabinet, and the associated wiring in the controller cabinet itself.The wire used in the street loop should be rated for direct burial. The wire should be of the cross-linked polyethylene (XLPE) insulated type. PVC insulated type of wire should always be avoided. The sealant should be carefully chosen to match the application and pavement. A hard setting epoxy should never be used with asphalt.The loop wires should be held into the bottom of the saw cut with backer rod. The loop wire should be twisted with a minimum of 5 twists per foot between the loop itself and the splice point. This is usually the hand hole or pull box at the side of the road.At this point, the twisted loop wires must be soldered to the lead-in cable. If crimp type connectors are used, they must be soldered after crimping. After soldering, the splices must be protected with a moisture-proof seal.The feeder cable used to extend the lead-in, must be a shielded, twisted pair with high-density polyethylene insulation. The termination of the feeder cable in the controller cabinet must also be soldered if crimp type terminals are used. The use of wire nuts and other improper methods of connections will result in problems with the detection system.7. Trouble AnalysisThe following chart should be used to troubleshoot the sensor unit and installation. If the DSP-222 itself is suspect, see section 8 for a complete internal testing sequence.a) Neither channel responds to vehicles. Power supply fault.The DSP-222 requires a 24 VDC nominal supply. The sensor unit will operate at voltages as low as 16 volts. However, supply voltages below this may result in the sensor unit entering a reset state. In this case, the unit will appear to be non-functional.b) Reset line held low.This fault is likely to affect all units in the rack since the external reset line is usually common to every card rack position. Measure the voltage on the external reset line. If it is below approximately 12 volts, remove each unit one by one until the reset line returns to the power supply level (approximately 24 volts). The unit that was removed last should be checked carefully for other faults. See section 8.c) Channel does not detect all vehicles.Sensitivity is too low. Increase sensitivity by one setting and observe operation.d) Channel is noisy/chatters/gives false detect calls.Two or more units are interfering with each other (crosstalk). Adjust the frequency switches on all units that exhibit crosstalk. Continue this procedure until all affected channels are corrected.8. Troubleshooting SequenceApply 24 ±1 volt power to the unit. Connect a loop test box with an inductance of approximately 115 microhenries to the loop inputs pins D and E (channel 1) and pins J and K (channel 2) to simulate the connection of loops.NOTE: All of the following signal measurements are referenced to logic ground.a) Unregulated power supply.Voltage across capacitor C16 should be 24 ±1 volt. This voltage can also be measured at the input of regulator U3 and/or U2.Possible component faults are diode D6 or resistor R36.b) Regulated 12 volt power supply.Voltage at output of U3 (across capacitors C17) should be 12 ± .2 volts. Possible component fault is the voltage regulator U3.c) Regulated 5 volt (logic) power supply.Voltage at output of U2 should be 5 ± .2 volts.Possible component fault is the voltage regulator U2.d) Regulated 5 volt (oscillator) power supply.Voltage at output of U4 should be 5 ± 0.2 volts.Possible component fault is the voltage regulator U4.e) Microcontroller clockWaveform at pin 10 of U1 should be a sine wave at 20 MHz with a peak to peak voltage of 1 to 2 volts. Note: This value will vary with the type of oscilloscope probe used. The value stated here is obtained using a Tektronix scope probe with a capacitance of 20 pF.Possible components at fault are the crystal X1 or microcontroller U1.f) Reset input to microcontrollerVoltage at pin 1 of U1 should be 5 volts ± .2 volts. Check to insure pin C on the detector is high--approximately 24 volts.Possible components at fault are transistors Q9, Q10, or diode D5.g) Loop oscillator outputConnect an oscilloscope to pin 13 (pin 12) of U1. Observe the square wave to be the same frequency as the loop oscillator. At this point, a simulated call should be introduced at the test box. Observe a slight frequency increase at this point.If there is no square wave at this point a defective component in the oscillator circuit may exist. Possible components at fault are Q1 (Q4), Q2 (Q5), Q3 (Q6), D3 (D4) or the potcore isolation transformer T1 (T2).h) Outputs and indicatorsVerify that the opto-isolated outputs conducts only when the front-panel detect LEDs are on.Possible fault areas are: Transistor Q7 (Q8) or the dual opto-isolator U2 or LED2 (LED1)9.

SpecificationsPower Supply:24 VDC ±20%, 80 ma maximum for both channels.Loop Input:The loop inputs incorporate lightning and transient protection devices and the loop oscillator circuitry is transformer isolated. The lightning protection will withstand the discharge of a 10 microfarad capacitor charged to 2,000V across the loop inputs or between any loop input and earth ground.Tuning:Each channel of the DSP-222 series will automatically tune to any loop and lead-in combination within the tuning range upon application of power or when a valid reset signal is received. A channel can be reset by adjusting mode, sensitivity, or frequency.Tuning Range:50 to 750 µH with a “Q” greater than 5.Lead-in Length:The unit will operate with lead-in (feeder) lengths up to 2,000 feet with Caltrans types A, B, or Q loops in all configurations as defined by California Standard Plan ES-5A & B.

The system is able to detect shorted or open loop systems, as well as a sudden change of inductance exceeding 25 % of the nominal value. If a fault is detected on a channel, the Fail LED will flash in a sequence related to the type of fault. The channel output will remain in the detect (call) state. If the fault condition is removed, the detect LED and the output will return to normal operation.High-Intensity LED Indicators:Each channel has a high-intensity red LED indicator to indicate the presence, or “call” and a high-intensity green LED indicator to indicate a failure in the roadway loop system.Front Panel Controls:Front panel mounted DIP switches allow the user to select sensitivity, pulse/presence and frequency on each channel.Operational Modes:Pulse - 125 ms ±25 ms momentary outputPresence Time - Meets or exceeds the State of California (Caltrans) Specifications. (Minimum presence = 10 minutes for a change of inductance of 0.06% and minimum presence = 3 minutes for a change of inductance of 0.02%)Note: When operating in the pulse mode, a vehicle remaining over a loop will inhibit further pulse outputs from being issued for a period of 2 seconds after which time vehicles passing over the loop will again be detected.Sensitivity:One of seven settings may be selected to optimize detection on varying loop and lead-in configurations. Sensitivity is defined as the minimum percentage change in L/L of the total inductance (loop plus lead-in). Selecting level 0 will switch the channel off.

System RequirementsThe UCA222 is PC and Mac-compatible. Therefore, no installationprocedure or drivers are required for the correct functioning ofthe UCA222.To work with the UCA222, your computer must fulfill thefollowing minimum requirements:2.1 Hardware connectionUse the USB connecting cable to connect the unit to yourcomputer. The USB connection also supplies the UCA222 withcurrent. You can connect a variety of devices and equipment tothe inputs and outputs.3. Controls and Connectors(1) POWER LED – Indicates the status of the USBpower supply.(2) OPTICAL OUTPUT – The Toslink jack carries an S/PDIFsignal which can be connected via a fiber optic cable.(3) PHONES – Connect a standard pair of headphonesequipped with a 1/8" mini plug.(4) VOLUME – Adjusts the volume level of the headphonesoutput. Turn the control fully to the left before youconnect the headphones to avoid hearing damage causedby high volume settings. Turn the control to the right toincrease the volume.(5) OUTPUT – Connect to a speaker system using stereo RCAcables to monitor the audio output from the computer.(6) INPUT – Connect desired recording signal using audiocables with RCA connectors.(7) OFF/ON MONITOR – With the MONITOR switch OFF,the headphone output receives the signal from the computer over the USB port (same as the RCA output jacks). With the MONITOR switch ON, the headphones receive the signal connected to the RCA INPUT jacks.(8) USB CABLE – Sends information to and from your computerand the UCA222. It also provides power to the device.4. Software Installation• This device requires no special setup or drivers, just plug it into a free USB port on a PC or Mac.•The UCA222 comes with a free version of Audacity editing software. This will help make the transfer process quick and simple. Simply insert the CD into your CD-ROM drive and install the software. The CD also contains VST plug-ins, ASIO drivers and various freeware.◊ Note – When the UCA222 is bundled with otherBEHRINGER products, the included software may vary. In the instance that the ASIO drivers are not included, you may download these from our website at .5. Basic OperationThe UCA222 provides an easy interface between yourcomputer, mixer and monitoring system. Follow these steps for basic operation:1) Connect the UCA222 to the computer by plugging theUSB cable into a free USB port. The power LED will light automatically.2) Connect the audio source that is to be recorded, such as amixer, preamp, etc. to the INPUT stereo RCA jacks.3) Plug a pair of headphones into the 1/8" PHONES jack andadjust the volume with the adjacent control. You may also monitor the output by plugging a pair of powered speakers into the OUTPUT stereo RCA jacks.4) You may also send the stereo signal in digital audio format(S/PDIF) to an external recording device via the OPTICAL OUTPUT using a Toslink fiber optic cable.6. Application DiagramsUsing a mixer to record in astudio environment:The most common application for the UCA222 is doing studio recording with a mixer. This will allow you to record several sources at once, listen to the playback, and record more tracks in sync with the original take(s).• Connect the mixer’s TAPE OUT to the INPUT RCA jacks on the UCA222. This will allow you to capture the overall mix.• Plug the USB cable into a free USB port on your computer.The POWER LED will light up.• Connect a pair of powered monitor speakers to the UCA222 OUTPUT RCA jacks. Depending on what type ofinputs your speakers accept, you may need an adapter.• You may also monitor the input signal with a pair of headphones instead of or in addition to the monitorspeakers. Turn the OFF/ON MONITOR switch to the ‘ON’position. Plug a pair of headphones into the PHONES jack and adjust the volume with the adjacent control. This will be preferable if the mixer and computer are in the sameroom as the instruments being recorded.• Take some time to adjust each channel level and EQ to ensure a good balance between the instruments/sources.Once the mix has been recorded you will be unable tomake adjustments to just one channel.• Set the recording program to record input from the UCA222.• Press record and let the music rip!Recording with a preamp such as the V-AMP 3:Preamps such as the V-AMP 3 provide a great way to record a wide selection of high-quality guitar sounds without the hassle of placing a mic in front of a conventional amp. They also allow you to record late at night without tempting your roommates or neighbors to strangle you with your own guitar cable.• Plug a guitar into the instrument input of the V-AMP 3 using a standard ¼" instrument cable.•Connect the stereo ¼" outputs on the V-AMP 3 to the stereo RCA inputs on the UCA222. This will likely require adaptors. You may also use the stereo RCA to ¼" TRS cable that is included in the V-AMP 3/UCA222 package bundle to connect from the V-AMP 3 headphone output to the UCA222 RCA inputs.• Plug the USB cable into a free USB port on your computer. The POWER LED will light up.• Adjust the output signal level on the V-AMP 3.• Set the recording program to record input from the UCA222.•Press record and wail!7. Audio ConnectionsAlthough there are various ways to integrate the UCA222 into your studio or live set-up, the audio connections to be made will basically be the same in all cases:7.1 WiringPlease use standard RCA cables to connect the UCA222to other equipment:You can also use a ¼" adapter cable:8.

(1)退役专业接收机:是目前最容易搞到的。

a,晶体管接收机:139A/B::频率范围1。

5-18MHz,三个波段,三连调谐,体积不大。

139B是139A的发展型,用了许多的硅管,效果比139A要好,有2个陶瓷滤波器/其中一个是窄带的,灵敏度也很好,噪声也很低。

建议把它的原配耳机换掉,用另一种带软胶皮耳罩且里面是黄色震动膜盖的军用耳机代换,音量音质都有很大的提高。

它的阻抗是600欧姆,内部结构类似于老式的舌簧喇叭,不可用一般的32欧姆的立体声耳机代用,否则易损坏机器。

这种耳机还可以代换其他的国产军用接收机的原配耳机,效果也不错,但不包括XSD-12(56)的,它的耳机阻抗是2200欧姆。

139A/139B它们的价位一般在100元以下。

239/339:频率范围:1。

5-30MHz,六个波段,239主要是用锗管设计的。

三连调谐,二次变频。

339是239的发展型,噪声更低,也是二次变频,但是四连调谐,有多个陶瓷滤波器,主要用硅管设计的。

239的价位和339差不多,但性能比339差一些。

它们的价位一般在200-350元;77,77-A,70/70-2/,70-3:几种外观,电路类似,性能十分优秀的机器。

频率范围1。

5-31。

5MHz,15个波段,它们曾经是我国在70年代初生产的(来自:WWw. : 222收信机 )最好的晶体管接收机,是短波一级收信机。

七连(77和77-A)或八连(70系列)调谐,高放调谐回路十分考究,比目前几乎所有的包括数万元的高档进口机还要讲究。
