Description
Technical field
The utility model relates to a kind of traffic signal light intelligent control system.
Background technology
At present, traffic lights operate with timer, realizing period, cannot carry out regulable control according to the real-time operating conditions of traffic by setting the how long time which, direction, crossroad one may be caused too to block up, and other direction is unimpeded does not even have vehicle to pass through, and makes troubles to driving.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of traffic signal light intelligent control system.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of traffic signal light intelligent control system described in the utility model, it is characterized in that: comprise 2 front end vehicle Flow Detection equipment, 2 radio transmission apparatus and back end signal lamp opertaing device, described 2 front end vehicle Flow Detection equipment include AT89C51 and the heat that is connected with AT89C51 releases infrared sensor detection module, real-time clock module, power circuit block, display module, serial line interface, described 2 radio transmission apparatus include gsm wireless transmitter module and gsm wireless receiver module, the signal lamp module that described back end signal lamp opertaing device comprises PLC and is connected with PLC, power module, 2 serial line interfaces, described power module is also for signal lamp module is powered, described 2 front end vehicle Flow Detection equipment are all connected with gsm wireless transmitter module by serial line interface and communicate to connect with the back end signal lamp opertaing device being connected with 2 gsm wireless receiver modules by 2 serial line interfaces.
Compared with prior art, the beneficial effects of the utility model:
A kind of traffic signal light intelligent control system described in the utility model, front end vehicle Flow Detection module carries out pulse analysis by the information of vehicle flowrate that pyroelectric infrared sensor detection module imports into by AT89C51 and record and calculating vehicle flowrate, and the back end signal lamp opertaing device in the direction of being advanced to car by gsm wireless transmitter module when real-time traffic flow amount meets or exceeds definite value carries out single-point one-way communication, back end signal lamp opertaing device is according to the control model of control signal switching signal lamp.When only having a direction to pass control signal back, PLC can change the control model of signal lamp according to control signal, and when both direction all passes control signal back, the control model of signal lamp is constant.This system according to the action of information of vehicle flowrate cooperation control adjacent traffic lights, can realize the object of Contrast tuned imaging traffic lights, is beneficial to alleviation congestion in road, improves environment.
Accompanying drawing explanation
Fig. 1 is the system chart of a kind of traffic signal light intelligent control system described in the utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of traffic signal light intelligent control system described in the utility model, it is characterized in that: comprise 2 front end vehicle Flow Detection equipment, 2 radio transmission apparatus and back end signal lamp opertaing device, described 2 front end vehicle Flow Detection equipment include AT89C51 and the heat that is connected with AT89C51 releases infrared sensor detection module, real-time clock module, power circuit block, display module, serial line interface, described 2 radio transmission apparatus include gsm wireless transmitter module and gsm wireless receiver module, the signal lamp module that described back end signal lamp opertaing device comprises PLC and is connected with PLC, power module, 2 serial line interfaces, described power module is also for signal lamp module is powered, described 2 front end vehicle Flow Detection equipment are all connected with gsm wireless transmitter module by serial line interface and communicate to connect with the back end signal lamp opertaing device being connected with 2 gsm wireless receiver modules by 2 serial line interfaces.
A kind of traffic signal light intelligent control system described in the utility model, front end vehicle Flow Detection module carries out pulse analysis by the information of vehicle flowrate that pyroelectric infrared sensor detection module imports into by AT89C51 and record and calculating vehicle flowrate, and the back end signal lamp opertaing device in the direction of being advanced to car by gsm wireless transmitter module when real-time traffic flow amount meets or exceeds definite value carries out single-point one-way communication, back end signal lamp opertaing device is according to the control model of control signal switching signal lamp.When only having a direction to pass control signal back, PLC can change the control model of signal lamp according to control signal, and when both direction all passes control signal back, the control model of signal lamp is constant.This system according to the action of information of vehicle flowrate cooperation control adjacent traffic lights, can realize the object of Contrast tuned imaging traffic lights, is beneficial to alleviation congestion in road, improves environment.
