The invention relates to a four-port track circuit processing system and an implementation method thereof, the system comprises a digital control unit, the digital control unit is internally provided with two sending ends and two receiving ends; the digital control unit outputs a corresponding frequency shift signal according to the low-frequency coding information and the correspondingly configured carrier frequency information of the port in front of the corresponding outdoor train in the direction information, and the other port outputs a corresponding frequency shift signal according to the configured carrier frequency information and default low-frequency coding information; the two receiving ends are set as side line ports and respectively receive signals sent by the far-end transmitter, the two receiving ends are determined to be free sections when both receiving ends are determined to be free sections, and the two receiving ends are determined to be occupied sections when any port is determined to be occupied sections. According to the invention, two paths of independent multi-coded frequency shift signals and two paths of independent frequency shift signal receiving ports can be output, and frequency shift information returned by a steel rail can be demodulated, so that whether a section is occupied by a train or not can be judged.
本发明涉及一种四端口轨道电路的处理系统及其实施方法,系统包括数字控制单元,所述数字控制单元内设置有两路发送端和两路接收端;所述数字控制单元根据所述方向信息中对应室外列车前方的端口按照低频编码信息及相应配置的载频信息输出相应的移频信号,另外一个端口按照配置的载频信息及默认低频编码信息输出相应的移频信号;所述两路接收端设置为侧线端口,分别接受远端发送器发送的信号,两路接收端均认定为空闲区段则判定为区段空闲,任一端口认定为占用区段则判定为区段占用。本发明可输出两路独立的多种编码的移频信号及两路独立的移频信号接收端口,可对钢轨返回的移频信息进行解调,从而判断出区段是否有列车占用。
