Output and alternating current 220V output, power to the devices such as PLC and receiver, motor.
Emitter and receiver can select existing matured product in the market, such as the JTY-HF- of bay company
GST102 molded line type light beam sense cigarettes（Mist）Detector can meet functional requirement of this system to detector；Build-in function is powerful micro-
Processor can judge the light quantity signal received, according to road transverse direction index, threshold value is arranged, converts the signal to 4
~20ma analog signals transfer to resume module；Built-in microprocessor has the function of compensation circuit, can cancel or compensate for because
The sensitivity that the aging etc. of dirt accumulation, position offset and transmitting tube makes reception signal reduce and generates declines, and prevents to miss
Alarm；With automatic calibration function, it is ensured that debugging is rapidly completed, simple, convenient；With self-diagnostic function, can monitor interior
Portion's failure；The variation of belt road visibility index and vehicle blocking etc. transmit to module and believe according to program setting under normal circumstances
Number；Built-in microprocessor is microcontroller, can be flexibly into line program setting, parameter modification.
Specifically, as shown in Fig. 2, a highway traffic accident/mist prediction occurring device includes 100 detectors, respectively
The adjacent 10 meter ampere dress of detector.One section can arrange that multiple prior-warning devices, the protection domain of adjacent prior-warning device can have
It partly overlaps, to realize redundancy.
Expressway speed is calculated by 120KM/h, 33.33m/s is converted into, by person's development time, braking time, vehicle
In energy, pavement behavior etc. are considered in, consider by total time 6s, i.e. about 33.33*6 ≈ 200m are sent out by away from emergency situations herein
At raw outside 190m（That is the distance between 20 detectors）Start to alarm.Specific work process is illustrated below：
1：In the case of low visibility, there is group's mist in front somewhere：
（1）Assuming that mist is rolled into a ball in front recently appears in detector 1, the i.e. position of A1, B1, A indicates that transmitter, B indicate to receive
Device, the luminous flux that the appearance of group mist W makes receiver receive decline, and B1 judges visibility according to the lateral index of quantization
Signal is actively fed back to processor by longitudinal index, and action command is issued 1~No. 20 detector by processor after judging, and 1~20
Number detector LED light flicker, voice guard alarm under passive requirement action, realize reminding effect, while 1~No. 20 detection
Device continues transmitting and receives infrared beam, continues to detect lateral visibility index；Remarks：To avoid occlusion receiver from connecing
Optical signal is received, it is more than just to send out warning message after not receiving optical signal within 3 seconds that receiver, which is arranged, in system；
（2）If group mist W continues to be expanded to No. 18 detectors at this time, B18 receivers are judged according to the lateral index of quantization
Signal is actively fed back to processor, action command is issued 18~No. 38 spies after processor judgement by longitudinal index of visibility
Device is surveyed, reminding effect is realized in 18~No. 38 detectors LED light flicker, voice guard alarm under passive requirement action；Successively
Analogize；
（3）If group's mist appears in the position of detector 95 recently, signal is actively fed back to processor by 95 receivers, is handled
Action command is issued into 95~No. 100 detectors after device judgement, 95~No. 100 detectors LED light under passive requirement action is dodged
Bright, voice guard alarm；Signal is actively fed back to the processor of upstream prior-warning device, upstream early warning dress by 95 receivers simultaneously
Action command is issued into 95~No. 115 detectors after the processor judgement set, 95~No. 115 detectors are under passive requirement action
LED light flicker, voice guard alarm；The full section early warning that redundancy is realized with this, avoids the occurrence of neutral gear；
（4）Controlling alarm after group's mist disappearance.Default group's mist disappearance system reset after ten minutes, it is assumed that detector 1
Group's mist disappearance at place, visibility good, then after ten minutes, signal is actively fed back to processor by B2 receivers, and processor judges
Action command is issued into 1~No. 20 detector afterwards, 1~No. 20 detector stops LED light flicker under passive require, stops sound
Alarm equipment alarm；If but still having a mist at No. 17 detectors, 1~No. 16 detector stops LED light flicker, stops audible alarm
Device is alarmed, B17 receivers（It is not drawn into figure）According to the lateral index of quantization, longitudinal index of visibility is judged, actively will
Signal feeds back to processor, action command is issued 17~No. 37 detectors after processor judgement, 17~No. 37 detectors are in quilt
The dynamic lower LED light of requirement action flickers, voice guard is alarmed, and so on, realize reminding effect；I.e. a detector connects simultaneously
When receiving " bright " and " not working " two instructions, certain " bright " is configured with "or" logic herein；
（5）When corresponding mist, medium mist, dense fog, mist wall, LED light flicker frequency（Audible alarm frequency）Be respectively 1s,
0.5s, 0.25s, it is always on（Chang Xiang）, mist severity rolled into a ball in front of the driver of rear to inform with this, deceleration is taken, enhances your vigilance
Measure；
2：In the case of folk prescription or both sides' traffic accident：
Under folk prescription or both sides' traffic accident, vehicle stops, and it is more than 3s that receiver, which does not receive optical signal, receiver active at this
Signal is fed back into corresponding module, action command is issued into follow-up 20 detectors after module judgement, this 20 detectors are in quilt
The dynamic lower LED light of requirement action flickers, voice guard is alarmed, and realizes and reminds；If just traffic accident vehicle does not block light-path,
Driver goes to block rear nearest transmitter or receiver with most fast motion, and realization artificially makes receiver active feedback signal,
Realize alarm.Remaining motion flow, redundancy setting are the same as setting 1（1）~（3）, difference is folk prescription or both sides' traffic accident state
Under, LED light flicker frequency（Audible alarm frequency）To be always on（Chang Xiang）, inform that subsequent vehicle slows down, slowly even stops immediately.
In traffic accident processing procedure, accident vehicle is removed, and it is normal to phase out LED for light-path normally system reset after ten minutes
Bright, setting is the same as 1（4）.
In the present embodiment, transmitter, receiver can be arranged in two lateral rail of track, be convenient for maintenance test；Using LED light
And audible alarm, enable to be easier to obtain warning message when night running；Road lamp power supply is utilized, does not have to individually power supply；It can be certainly
Cleaning, automatically resets, non-maintaining；Alarm distance is adjustable, and can shift to an earlier date longer distance setting to multi-happening section alarms；To mist etc.
The feature that emergency situations forecast is difficult, regionality is strong, can monitor in real time；It can also be applied to long tunnel highway etc.；Traffic police handles high
When fast accident, it can also shift to an earlier date 190 meters of setting sound-light alarms, and not easily damaged, improve Personal Safety when traffic police's process accident；
Expense is relatively low, and module, bus price are relatively low, easy for construction.
It is a kind of preferred embodiment of the utility model above, but it is to be understood that above-mentioned specific description should not be understood
For the restriction to the utility model in essence and range, obvious variant that those skilled in the art make further according to above-described embodiment or
Person replaces the range for still falling within the utility model protection.
