Development Of Gate Traffic Control System

With the rapid development of domestic rail transit and higher requirements for the field of security,the traditional gate has been unable to meet the demand.Therefore,the development of more intelligent,safe,beautiful,modern gate has great significance for improving the efficiency of public transit and enhancing the security of important places.Under the background of a company’s project,this paper has designed the hardware and software of the control system,and does in-depth research on the intelligent recognition technology.This dissertation expounds the development and field commissioning process of the gate control system.First of all,sufficient research on the functional requirements,technical indexes and composition structures of the gate machine is prepared for the following design and implementation.Secondly,both the hardware and software are designed for the control system.The tasks of the system hardware design consist of hardware system principle analysis,component selection,circuit schematic drawing and PCB layout.The system software development mainly contains embedded environment construction,device driver programming,explanation of application flow chart,research on the position mapping and position attribute of infrared sensor,visual interface design.Then,by combining the three methods of area recognition,key points recognition and event recognition,the traffic recognition event vectors are obtained,which can identify the authorized passage behavior of single or multiple pedestrians and unauthorized passage behavior of trailing or reverse intrusion,further improving the accuracy of traffic recognition.Finally,through the gate experimental platform,this paper makes a lot of tests on the traffic identification ability of this system,position mapping and position attribute configuration of infrared sensor.More importantly,this gate control system has been installed to the actual scene,and the practical application results show that this system can meet the actual demand.
