Abstract

The invention relates to a non-fixed shunting locomotive safety protection system based on a mobile communication network. The system comprises a central shunting safety protection subsystem, the mobile communication network and non-fixed shunting locomotive vehicle-mounted equipment. The non-fixed shunting locomotive vehicle-mounted equipment is connected with the central shunting safety protection subsystem through the mobile communication network; and the mobile communication network adopts a dual-network redundant communication network. Compared with the prior art, by using the system of the invention, a communication range is expanded, and safety and stability of single-path 4G communication are enhanced through a double-path 4G redundant communication mode.

Description

technical field [0001] The invention relates to a safety protection system for a non-fixed shunting locomotive, in particular to a safety protection system for a non-fixed shunting locomotive based on a mobile communication network. Background technique [0002] The wireless shunting locomotive signal and monitoring system (hereinafter referred to as the STP system) is an intelligent, configurable shunting safety protection system suitable for different stations. It is flexibly applied to the fixed shunting locomotives of various domestic railway bureaus. working station. The STP system consists of ground equipment, on-board equipment and external equipment. The system realizes communication between ground equipment and on-board equipment through wireless data transmission stations, and realizes wireless monitoring and safety protection for shunting operations of multiple locomotives in the station. [0003] In the prior art, the station where the STP system is installed is...
