Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be pointed out that those skilled in the art can make some modifications and improvements without departing from the inventive concept, and these all belong to the protection scope of the present invention.
[0016] The low-power shunting protection device of the present invention obtains the lamp position information from the 220V lighting circuit of the signal machine, obtains the induced current information from the filament of the signal machine, and then collects the message signal from the output end of the message transmission module driver. The interface module passes the message The message information returned by the A interface of the transmission module is compared with the collected lamp position in...

The low-power-consumption shunting protection device for message closed-loop detection comprises an interface module, a message transmission module and a Cr interface connected between the interface module and the message transmission module, the Cr interface comprises an interface Cr1 and an interface Cr6 which are transmitted from the interface module to the message transmission module, and a Cr2 re-inspection signal transmitted from the message transmission module to the interface module; the message transmission module is compatible with a standard C interface of the active transponder and also compatible with a Cr interface; and when the message transmission module is activated by the BTM antenna of the train, the message transmission module transmits an FSK signal containing Cr1 interface data to the BTM antenna, and outputs a Cr2 re-check signal to the interface module at the same time. The method has the technical advantages that the Cr interface is high in function reliability and low in power consumption, closed-loop monitoring of message data sent by the message transmission module can be achieved, and the low-power-consumption requirement of single-point double control of the shunting protection system can be met.
Description
technical field [0001] The invention relates to a low-power shunting protection device for message closed-loop detection. Background technique [0002] The shunting protection device is a low-cost shunting protection equipment, which is scattered and installed near the trackside signal. The shunting protection device is divided into an interface module (trackside part) and a message transmission module (ballast bed part). The interface module sends the corresponding message stored by itself to the message transmission module by collecting the lighting status of the signal machine. The module transmits the message to the on-board equipment of the EMU through the vehicle-ground communication to realize the protection of the shunting operation of the EMU. [0003] The shunting protection device obtains working power from the signal machine. In order not to affect the normal operation of the signal machine, a strict limit is put on the power consumption of the shunting protecti...
