The invention discloses a train occupancy inspection device without a signal cable, which belongs to the technical field of railway signals, and comprises a signal processing module for generating a detection frequency shift signal according to a coding condition; the transmission matching module is used for transmitting the detection frequency shift signal to a track, receiving a feedback frequency shift signal of a track circuit of a current section and isolating a feedback frequency shift signal of an adjacent section; and the signal processing module is used for demodulating the feedback frequency shift signal according to the section parameter configuration information sent by the control equipment to obtain feedback information and sending the feedback information to the control equipment and the monitoring diagnosis module. The electronic transmitting and receiving devices of the track circuit system are distributed in a scattered mode, signal cables are omitted, control information is transmitted through optical fibers, electronic device trackside and digital board card are achieved, and the problems that in the prior art, the cable failure rate is high, the control distance is limited, and field maintenance is inconvenient can be solved.
本发明公开了一种取消信号电缆的列车占用检查装置,属于铁路信号技术领域,其包括用于根据编码条件生成检测移频信号的信号处理模块;用于传输检测移频信号至轨道,以及接收当前区段轨道电路的反馈移频信号并隔离相邻区段的反馈移频信号的传输匹配模块;用于根据控制设备发送的区段参数配置信息解调反馈移频信号得到反馈信息,发送至控制设备及监测诊断模块的信号处理模块。本发明采用将轨道电路系统的电子发送、接收设备分散布设,通过取消信号电缆,改为控制信息通过光纤传输,实现电子设备轨旁化和数字板卡化,能够解决现有技术中电缆故障率较高、控制距离有限以及现场维护不便等问题。
