5th, distinct optical designs；
6th, photoelectricity beam can penetrate the special environment resistant ability of compound glass；
7th, outdoor dual-beam, adapts to the bad weathers such as rain, mist, snow；
8th, special infrared filtering eyeglass and circuit resist strong light interference；
9th, beam interference minimumization is suitable for various complex environments；
10th, infrared emission and infrared receiver are integrated on same pcb board, are solved infrared emission well and infrared are connect
The interference that the same side is brought is received in, is avoided as traditional infrared is to being designed to 2 kinds of schemes penetrating.
11st, when infrared emission wherein all the way to penetrating failure when, in addition infrared emission remains to work normally all the way；
12nd, dedicated programming interface has been reserved, has been more convenient field upgrade program.
Its specific embodiment circuit is as shown in Fig. 2, the infrared transmitting tube that the design uses（KEL5002A）It is a kind of efficient
The GaAlAs infrared light-emitting diodes of rate, light blue plastic-packaged, high-power transmitting tube is, it can be achieved that the communication of middle and long distance.From
And the lens in conventional infrared opposite-type detector can be saved, also greatly promote convenience during assembling product.
Infrared transmitting circuit is made of R2, R3, D1 and Q1, and R2, R3 are current-limiting resistance, can adapt to radiating circuit different
Operating voltage, when transmitting infrared ray goes to control corresponding controlled device, the distance of control is directly proportional to transmission power.In order to increase
Add the command range of infrared ray, infrared light-emitting diode need to work in pulse condition, because of pulsating（Modulation light）Effective biography
It send distance directly proportional to the peak point current of pulse, only need to improve peak I p as possible, just can increase the transmitting range of infrared light, improve
The method of Ip is the width т for reducing pulse duty factor, i.e. compression pulse.Infrared light-emitting diode is made to generate modulation light, only
The pulse voltage of certain frequency need to be added on driving tube.The impulse waveform of usual infrared emission is by NAND gate or 555 timings
Device generates the square wave of a 38KHz, then it is modulated, and to realize desired pulse voltage, and our company is then directly to pass through
Microcontroller（STC15F101W）The desired pulse voltage of output, then control Q1 base stages are gone, realize that circuit is simple and effective.
Infrared receiving tube（YMG-F238H）Using a kind of integrative infrared receiver, it is by PIN photodiodes, preposition
Amplifier and demodulator are integrated with epoxy encapsulation, are had and are received infrared signal, built-in signal amplification, 38KHz filtering, wave
The effect of shape detection output.Infrared communication can all be limited and interference as other communication modes by environmental condition, infrared
The interference source of communication is mainly incandescent light and sunlight, and the shadow of optical noise can be reduced using the receiver with optical filter
It rings.The infrared receiving terminal of 2 more conventional feet enormously simplifies receiving circuit；In addition its packaged type is consistent with transmitting tube, and compared with
The infrared receiving tube installation of TSOP4838 type packages is more advantageous.
Infrared transmitting circuit and receiving circuit are combined, by microcontroller（STC15F101W）It is controlled, two
Identical photoelectric beam detector forms a set of infrared emission detection device, single to emitter time division emission and reception infrared signal, and
Whether detection party B and other side receive signal, if party B or other side are not connected to infrared signal, send out alarm to host immediately
Signal.After infrared receiving terminal receives 38KHz infrared pulse signals, processing is identified in notice MCU.MCU, which is learnt, receives signal
Afterwards, infrared emission pulse width is adjusted immediately, and other side is notified to have been received by signal.So as to which one's own side effectively be avoided to emit what signal was brought
Interference.
Pedestrian's clearing lamp mainly indicates walk and no entry.It is same by green arrow and red fork indicator light
Screen composition；Green arrow is by 32 light emitting diodes（It is green）Composition corresponds to lamp plate circuit and may be designed as：32 light emitting diodes+1
A 3V zener diodes, 3 string 11 of composition is simultaneously（270 Ω of band）Circuit；Red fork is by 28 light emitting diodes（It is red）Composition corresponds to
Lamp plate circuit may be designed as：+ 2 2V zener diodes of 28 light emitting diodes, 5 string 6 of composition is simultaneously（130 Ω of band）Circuit；It is defeated
Enter voltage for 12V.
Green arrow and the same screen schematic diagram of red fork indicator light and display renderings are as shown in Figure 3,4.
The current traffic behavior of understanding that pedestrian's traffic lights detection module can allow pedestrian more eye-catching, while allow street crossing people's row
Phonetic warning stake is more attractive.Red running lamp is by 12 light emitting diodes（5 red tape Ф of Ф, 10 small lamp bulbs）With 6 560 Ω/0.25W
Resistance forms；Green running lamp is by 12 light emitting diodes（5 greenbelt Ф of Ф, 10 small lamp bulbs）With 6 510 Ω/0.25W resistance composition；
Input voltage is 12V.
Running lamp schematic diagram and display renderings are as shown in 5,6.
Voice broadcast module is the BY8301-16P voice modules for having the function of USB download onlines, and voice can be good
The auditory tone cues of various hommizations are sent out to the pedestrian for preparing street crossing according to the state of pedestrian lamp（The voice content can also be determined
System）, safety is important to note that when pedestrian being made especially to blind personage across road, so as to fully demonstrate traffic safety facilities
Human oriented design.Audio amplifier circuit uses independent operational amplifier circuit, can drive the loud speaker of 4 Ω/20W.Its schematic diagram such as Fig. 7
It is shown.
Voice prompting device basic functional principle：
Audio files all first is stored according to scheduled number in voice module, and main control chip is controlled by sending
Instruction is given to voice module, calls the audio file of the reference numeral of its storage inside, the voice module audio to be played this
File is exported by DACL and DACR feet to audio amplifier circuit, then reports out by loud speaker.
It is more convenient that pedestrian asks button then to provide the passerby that crossing wants help, and because button is positioned over outside, is
Prevent electric leakage from user being caused to get an electric shock, the detection circuit of outer button turns DC 5V power isolation modules by DC 5V（B0505S-
1W）It is isolated, which is isolated pressure voltage up to 1.5KV.Its schematic diagram is as depicted in figure 8.
Concrete principle is as follows：Hommization voice is reported by lower button：
1st, it when pedestrian signal lamp is in red light phase, presses pedestrian and button is asked to be reported：
（When countdown is invalid）It is red time now, woulds you please bear with.It makes a dash across the red light danger！
（When countdown is effective）It is red time now, woulds you please bear with, green light will be become after XX seconds.It makes a dash across the red light danger！
2nd, it when pedestrian signal lamp is in green light phase, presses pedestrian and button is asked to be reported：
（When countdown is invalid）Please quickly through observe traffic laws rule, and Everybody is responsible after confirmation safety.
（When countdown is effective）To be red light after XX seconds, please quickly through observe traffic laws rule, Ren Renyou after confirmation safety
Duty.
Main control module is responsible for coordinating each function module orderly normal work steadily, using high and low voltage isolation designing scheme,
Its circuit diagram is as shown in figure 9, its major function：1st, to the detection of pedestrian signal lamp lights state；2nd, Coordination Treatment is infrared right
The signal of detector offer is provided；3rd, judge that processing pedestrian asks the signal of button feedback；What the 4th, control voice prompting device was reported is interior
Hold；5th, coordinate the steady orderly normal work of each function module.
