Study and Realization of Control and Command System for Underground Traffic Signal

Liu Yijiang,Zhou Huimeng,Peng Chuwu,Li Yi(Civil Engineering College,Hunan University,Changsha 410082,China)  
To solve the problem of the underground car's mutual jamming,it devise new control and command system for underground traffic signal,which can track real-timely and monitor underground car,it also can command and attemper car.The system adopts UltraHigh Frequency RFID(Radio Frequency Identification)technique and information technique,and describe the command and positioning system's topology structure relation,it separately solve the logic judgement of command system and problem of anti-collision.Management software of host computer and relevant hardware were designed.The system works well in action.RFID technique is applied in the control system for underground nonferrous metallic mines,and apply the topology structure theory in control logic,which have great theoretics and actical significance.
