Summary of the invention
For the safety factor problem that evening, pedestrian went across the road, the utility model for urban traffic control provide a kind of can allow at night pedestrian road safe passing and warning car intention, promoted the traffic safety at night.
The present invention adopts following technical scheme:
A kind of pedestrian's street crossing safety alarm device, comprise microprocessor, microprocessor connects photosensitive detection circuit, trigger pip testing circuit, time selection circuit, wireless transmit trigger circuit, wireless receiving circuit, red green sudden strain of a muscle warning lamp, the lighting circuit of exposing to the sun, trigger pip testing circuit connects echelette, described echelette is for detection of pedestrian, described photosensitive circuit determines whether evening for detection of surrounding brightness, and described red green exposing to the sun dodged warning lamp and lighting circuit for reminding car.
Described trigger pip testing circuit adopts TLP521 photoelectric coupled device.
Described time selection circuit adopts the action of toggle switch to carry out the length of select time.
Described wireless transmit trigger circuit are selected PT2292 wireless transmitter module.
Described wireless receiving circuit is selected PT2294-M4 wireless receiving module.
Described red green exposing to the sun dodged red, the green LED lamp of warning lamp employing high brightness.
Described lighting circuit adopts the LED lamp group composition of white high brightness.
Described microprocessor adopts the STC12 series monolithic with built-in analog-digital conversion function.
The utility model utilizes echelette as pedestrian detector, and according to photosensitive circuit, determines whether evening, and when if there is pedestrian's process evening, red green exposing to the sun dodged warning lamp and lighting circuit is opened, and reaches the object of reminding car to have new person's process.
Application by the utility model in urban transportation, the more bad place of road conditions allows pedestrian have a safer environment at night, also can allow car know that front has pedestrian to go slowly through good deceleration, the traffic that simultaneously the utility model is city night provides a kind of safe and reliable, applied widely, traffic administration auxiliary equipment with low cost, has good social benefit.

Embodiment
Below in conjunction with accompanying drawing, the present invention is done to further detailed description.
As Fig. 1, a kind of pedestrian's street crossing safety alarm device, comprise microprocessor, microprocessor connects photosensitive detection circuit, trigger pip testing circuit, time selection circuit, wireless transmit trigger circuit, wireless receiving circuit, red green sudden strain of a muscle warning lamp, the lighting circuit of exposing to the sun, trigger pip testing circuit connects echelette, described echelette is for detection of pedestrian, described photosensitive circuit determines whether evening for detection of surrounding brightness, and described red green exposing to the sun dodged warning lamp and lighting circuit for reminding car.The power supply of device is supplied with by normal power supply, and the Switching Power Supply of process 12v is to master control borad; Trigger pip testing circuit adopts TLP521 photoelectric coupled device to detect echelette, photosensitive trigger pip, inputs to microprocessor, and determining whether has pedestrian's street crossing evening; The action of what time selection circuit was selected is toggle switch carrys out the length of select time, and the size of this time is to regulate according to the length of road; Wireless transmit trigger circuit select the radiating circuit of PT2292 wireless transmitter module composition in the time having pedestrian, to launch a signal; When having signal when, it carries out signal accordingly and moves the circuit of what wireless receiving circuit was selected is PT2294-M4 wireless receiving module composition to microprocessor; Red green exposing to the sun dodged red, the green LED lamp of warning lamp employing high brightness, while having at night pedestrian to go across the road, lights; Lighting circuit is made up of the LED lamp group of white high brightness; Microprocessor adopts the STC12 series monolithic with built-in analog-digital conversion function.
As in Figure 2-4, a kind of embodiment shell of pedestrian's street crossing safety alarm device presents square column type, adopts paired set-up mode, and left-hand unit is placed on zebra crossing left side, and right-hand unit is arranged on zebra crossing right side; Square body front surface is provided with emitting antenna 1, receiving antenna 2 and lighting lamp group 3, and the right surface of square body is provided with red quick-fried sudden strain of a muscle warning lamp 4 and green exposing to the sun dodged warning lamp 5, in square body groove at side surface inside, echelette 7 and photosensitive probe 6 is set.
As shown in Figure 5, the vertical view of pedestrian's street crossing safety alarm device setting at the scene, device is arranged on the road edge by zebra crossing entrance, echelette 7 correlation, in the time having pedestrian to go across the road, echelette 7 light are blocked, echelette 7 has detected pedestrian, signal is inputed to microprocessor by trigger pip testing circuit, photosensitive probe 6 judges whether evening according to brightness situation around, these two signals are simultaneously effectively as the trigger pip that has pedestrian's street crossing evening, in the time that have pedestrian to go across the road definite evening, red green exposing to the sun dodged warning lamp unlatching, and the red green sudden strain of a muscle warning lamp that exposes to the sun is arranged on the one side that car can be seen, remind vehicular traffic, the illuminating lamp of lighting circuit is opened simultaneously, illuminating lamp is arranged on pedestrian's side that need to illuminate of going across the road, going across the road for pedestrian is the road conditions of observing road.Road one side has detected that pedestrian goes across the road simultaneously, transmits by emitting antenna 1 at once, after the receiving antenna 2 on road opposite receives signal, also red green quick-fried sudden strain of a muscle warning lamp and illuminating lamp is opened.
