Frequency shift relay device for wireless shunting locomotive signal and monitoring system

Abstract

The invention relates to a frequency shift relay device for a wireless shunting locomotive signal and monitoring system. The device is installed between a ground communication building base station and a controlled train. The frequency shift relay device comprises a near-end host and a far-end extension set which are in communication connection with each other through intermediate frequency signals, the near-end host is arranged at a ground communication building base station and is in communication connection with the ground communication building base station, and the far-end extension set is arranged at the coverage edge of the communication building base station and is in communication connection with a controlled train. Compared with the technologies of the prior art, the device has the advantages that the wireless communication transmission capability is enhanced, and the coverage range of wireless communication is expanded.

Description

technical field [0001] The invention relates to a wireless shunting locomotive signal and monitoring system, in particular to a frequency-shifting relay device for the wireless shunting locomotive signal and monitoring system. Background technique [0002] Wireless shunting locomotive signal and monitoring system (hereinafter referred to as STP system) is a set of shunting safety protection system applied to stations, mainly composed of ground equipment and on-board equipment. The STP system realizes the communication between the ground equipment and the on-board equipment through the wireless data transmission station, and realizes wireless monitoring and safety protection for the shunting operation of multiple locomotives in the station. Therefore, the quality of wireless communication directly affects the stability, real-time and accuracy of data interaction between ground equipment and vehicle equipment. [0003] During the construction of the wireless communication net...

AI Technical Summary

Problems solved by technology

[0003] During the construction of the wireless communication network, due to the complex geographical environment of each station (for example: the area of ​​the station is too large, the distance between the signal machines on both sides of the station is far away, there are tunnels, mountains, bridges, obstacles, etc. in the station), the wireless The signal cannot completely cover the entire station, which directly affects the stability of the communication between the ground equipment and the on-board equipment, and further affects the safety protection of the STP system for locomotive shunting operations in the station
