Problems solved by technology

[0007] Thirdly, the current train approaching alarms mostly use medium and short-wave frequencies for transmission and reception, which are prone to interference and interference with other equipment, and the frequency occupation time is long and the frequency utilization rate is low;
[0008] Finally, the current train approaching alarms use analog signals for transmission, and code errors and missing codes often occur, resulting in low transmission quality and low transmission reliability.

Embodiment Construction

[0026] see figure 1 , figure 1 It is a basic composition diagram of the early warning system of the present invention. The early warning system includes: the on-board machine 1 installed on the running train, used to collect the driving data on the running train, send it out in the form of electromagnetic waves after encoding, modulation, and amplification, and receive the radio frequency signal carrying the alarm code, and decode it. , start the alarm device to give an alarm; the ground terminal equipment 2 is used to receive the radio frequency signal carrying the driving data, demodulate it, decode and restore the driving data, control the warning device to start the alarm, and send the radio frequency signal carrying the warning code. The ground terminal equipment 2 includes a crossing construction integrated machine 3 installed at the crossing and construction site, and a portable receiver 4 for repairing and maintaining railway facilities. When the vehicle-mounted mach...

Abstract

The train approach early warning system includes train device for collecting train running data, sending RF train running data after being coded, modulated and amplified, receiving RF signal with warning code, decoding the RF signal and warning via starting the warning unit; and ground terminal device for receiving the RF train running data with train running data, demodulating and decoding to obtain original train running data, controlling the warning unit to warn and sending RF signal with warning code in emergency. The ground terminal device includes road junction-construction site unit and portable receiver.

Description

technical field [0001] The invention relates to a wireless digital communication system, in particular to a train approach early warning system applied in railway departments. Background technique [0002] At present, the railway is a major choice of transportation for most people to travel. With the development of the economy and the change of people's ideas, the number of people going out to work, study and travel is increasing year by year, which requires the railway system to provide fast and convenient travel services. The speed of trains is increasing, and the number of trains running on the rails is increasing. However, railway facilities need to be maintained and people's safety needs to be guaranteed. Relying on a single railway diagram is far from being able to adapt to the modern management of the railway system. [0003] In the Chinese utility model patent application with the application number 96219637.1 and the invention name "a dual-channel fault display tra...
