Abstract

The present invention provides an analog demodulation circuit for obtaining a message from a ground electronic unit C interface, comprising: an interface circuit unit, connected with the ground electronic unit C interface, for receiving the C interface signal; a mutual inductance coil T1, connected with the interface circuit unit, with It is used to collect the voltage induction signal; the C1 signal analog demodulation unit is connected to the mutual inductance coil T1 to filter the C1 signal from the voltage induction signal and generate the DBPL encoded signal; the C6 signal energy detection unit is connected to the mutual inductance coil T1 for Filter out the C6 signal from the voltage sensing signal and detect the energy of the C6 signal; the signal processing unit is connected to the C1 signal analog demodulation unit and the C6 signal energy detection unit respectively, and is used to decode the DBPL encoded signal generated by the C1 signal analog demodulation unit , and determine whether the energy of the C6 signal meets the requirements. The invention can realize the analog demodulation and logical decoding of the C1 message signal, and simultaneously realize the energy detection of the C6 signal.

Description

technical field [0001] The invention relates to the technical field of railway communication signals, in particular to an analog demodulation circuit for acquiring messages from a C interface of a ground electronic unit. Background technique [0002] In the railway signal system, the ground electronic unit (LEU) is the key equipment for transmitting variable messages in the transponder system. It forms a point signal transmission system with the ground transponder and the on-board antenna. Devices can communicate information at decentralized points. [0003] The LEU needs to send the ground data to the automatic train protection system (ATP) through the C1 signal and the C6 signal. The C1 signal is the message sent by the LEU to the active transponder, and the C6 signal is for the LEU to provide energy to the active transponder interface circuit. [0004] The C interface is the interface between the LEU and the active transponder, and is mainly responsible for transmitting...
