摘　　要：为了解决城市轨道交通网络受到大量信号影响导致控制效果不佳的问题,进行了城市轨道交通专用通信综合网络信号智能控制系统设计。利用交换机组群通信方法,实现轨道交通全线的无线统一调度。通过CAN总线建立数据通信信道,传送指令数据。设计雷达传感系统结构,对回声信号进行接收与放大。构建基于模糊控制的信号输入输出模型,获取输出反馈信号,结合模糊自适应控制规律,控制延误时间信号、速度和间隔信号。实验结果表明,该系统能够控制网络信号幅度变化,延误时间在120 s之内,能够有效控制网络信号。In order to solve the problem of poor control effect caused by a large number of signals affecting the urban rail transit network,the signal intelligent control system of urban rail transit special communication integrated network is designed.The wireless unified dispatching of the whole line of rail transit is realized by using the switch group communication method.Establish data communication channel and transmit command data through CAN bus.The structure of radar sensing system is designed to receive and amplify the echo signal.The signal input⁃output model based on fuzzy control is constructed to obtain the output feedback signal.Combined with the fuzzy adaptive control law,the delay time signal,speed and interval signal are controlled.The experimental results show that the system can control the amplitude change of network signal,the delay time is within 120 s,and can effectively control the network signal.
