Description

A kind of traffic light control system based on FPGA

Technical field

This utility model is related to a kind of traffic light control system, and in particular to a kind of traffic light based on FPGA Control system.

Background technology

FPGA (Filed-Programmable Gate Array), i.e. field programmable gate array, are a kind of semi-custom electricity Road, is made up of configurable logic blocks, three parts of input/output module and interconnector.There is FPGA development process to invest Little, cycle is short, can program repeatedly, good confidentiality, the features such as autgmentability is strong, with the continuous progress of electronic fabrication processes, FPGA Integrated level more and more higher, stability becomes better and better, and price is but more and more lower, and FPGA has become Contemporary Digital design of circuit system One of preferred manner.

With the continuous improvement of our people's living standard, increasing personal and family has been owned by the private savings of oneself Car, a principal element for producing vehicle congestion are that the setting of urban traffic intersection traffic lights has such-and-such technology and pipe Reason problem.At present, the traffic light of China main cities traffic intersection all adopt the timing control of the chips such as single-chip microcomputer or PLC System, control form are single, it is impossible to adjusted according to the change of concrete traffic, and system peripherals circuit complexity, program are repaiied Change dumb, high expensive etc..

The content of the invention

In order to overcome the shortcoming of above-mentioned technology, the purpose of this utility model to there are provided a kind of traffic based on FPGA and believe Ship's light control system, can according to the current vehicle flowrate of traffic intersection number realizing the automatic timing of traffic light, with electricity Road is simple, it is highly reliable the advantages of.

In order to achieve the above object, the technical solution of the utility model is realized in：

A kind of traffic light control system based on FPGA, including image detecting senor 1, image detecting senor 1 Output control the input of vehicle detection module 2 in 6 with FPGA and be connected, the output of vehicle detection module 2 and vehicle flowrate The input connection of module 3, the output of vehicle flowrate module 3 are connected with the input of LED control module 4, vehicle detection module 2, Vehicle flowrate module 3 and LED control module 4 connect and compose FPGA controls 6, and the output of LED control module 4 is defeated with LED 5 Enter connection.

This utility model has the advantages that：The control of LED 5 is realized using FPGA controls 6, can be according to traffic The current vehicle flowrate in crossing number realizing the automatic timing of traffic light, have the advantages that circuit is simple, highly reliable.

Description of the drawings

Fig. 1 is structured flowchart of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is described in detail.

With reference to Fig. 1, a kind of traffic light control system based on FPGA, including image detecting senor 1, image detection The output of sensor 1 controls the input of vehicle detection module 2 in 6 with FPGA and is connected, the output of vehicle detection module 2 and wagon flow The input connection of amount statistical module 3, the output of vehicle flowrate module 3 are connected with the input of LED control module 4, vehicle detection Module 2, vehicle flowrate module 3 and LED control module 4 connect and compose FPGA controls 6, the output of LED control module 4 and LED The input connection of lamp 5.

Operation principle of the present utility model is：

The system receives the view data of 1 transmission of external image sensor with FPGA controls 6 as control core；By car Detection module 2 determines whether vehicle and passes through, and is counted by 3 pairs of vehicle flowrate quantity for passing through of vehicle flowrate module, LED Control module 4 is responsible for the result for receiving 3 statistics of vehicle flowrate module, according to corresponding rule, provides corresponding traffic light time, It is current to outside LED 5 to be controlled.
