In order to improve the signal control ability of urban rail transit,this paper puts forward a signal operation and maintenance control method of urban rail transit based on simultaneous same-frequency full-duplex frequency hopping control in a limited area.The urban rail transit signal model is constructed,and the spectrum separation and feature decomposition of urban rail transit signals are realized by the method of limited area full-duplex frequency hopping ad hoc network.Under the constraint of transmission capacity index,the filtering detection and frequency band separation of urban rail transit signals are realized by the method of large-scale path loss modulation,and the index system for measuring network performance is constructed.The same-frequency full-duplex steady-state control method is adopted to realize the intelligent operation and maintenance automatic control of urban rail transit signals.The integrated development and design of intelligent operation and maintenance automatic control system of urban rail transit signal is realized under the embedded DSP control component environment.The test results show that the signal interaction ability and anti-interference ability of urban rail transit signal control by this method are strong,and the intelligent operation and maintenance level of urban rail transit is improved.
