Study About Traffic Camera System Based On Embedded PLC

With the continuous improvement of China's comprehensive national strength and the economic level,the frequent occurrence of traffic accidents and more and more serious problems such as traffic illegal Pfeiffer.As a result,people dependence on traffic law automatically capture system has become increasingly intense,demand is widespread,not only requires more and more is also high.Law enforcement,in particular,the need for automatic traffic illegal capture system has not only stay in capture accurate and clear photos,more reasonable design,stable operation,and to have enough compatibility.At present,the market good and evil people mixed up illegal capture system integrators,technical level is uneven,and various electronic police system control system compatibility problems to different extent,which greatly limits the renewal speed of electronic police system,has clearly is difficult to meet the market demand of illegal traffic capture.According to capture the electronic police system control unit of the common problems and customer demand for high system stability,this topic proposed introduction of embedded PLC technology to improve the capture control unit multiple solutions of the problem.Concrete is triggered by the embedded PLC high-definition camera external shutter controller,so as to activate camera,start the capture,to improve the stability of the electronic police system capture unit work,at the same time to expand its system compatibility,reserved for the future system upgrades.Based on customer demand for vehicles illegal capture,this article system to the core of the embedded PLC of the capture unit is discussed,and the system architecture and working principle of electronic police system.Elaborated how to utilize external shutter control unit control high-definition cameras,and how to through the video detection is accomplished illegal vehicle automatic capture,plate automatic recognition and illegal information upload.Finally,the work done in this paper has carried on the system overall,to improve the system still exists in the question and the insufficiency,proposed improve idea and direction for the period ahead.This article system elaborated the introduction of embedded PLC technology in capturing control unit of the electronic police system principle of design,development,use,better for the existence of the traditional technology to solve the mistake taps,leakage capture such as insufficient accuracy,poor compatibility and unstable system.
