Railway disaster prevention early warning information transmitting system based on cell broadcast short message

Abstract

The invention relates to a railway disaster prevention early warning information transmitting system based on a GSM-R (Global System for Mobile Communications for Railway) cell broadcast way. The system comprises a vehicle-mounted terminal and a ground disaster prevention information transmitting center, wherein the vehicle-mounted terminal consists of a wireless transmitting unit and a display unit; and the ground disaster prevention information transmitting center consists of a cell broadcast center, a GPRS (General Packet Radio Service) interface server, a forwarding controller, a memory unit, a disaster prevention monitoring gateway, a GPRS gateway, a cell broadcast gateway, an internal data exchange unit, a time synchronizing unit, a management server and an operation management terminal. Due to the adoption of the system, railway disaster information (including wind, rain, snow, fallen objects and the like) can be transmitted to all motor train units and maintenance operation personnel in a controllable range close to a disaster occurring point in real time through a GSM-R cell broadcast service, the phenomenon of missing of time for adopting an optimal measure caused by overlong time for responding to and transmitting original disaster information is avoided, the instantaneity and reliability of disaster prevention early warning are improved, and the train running safety and disaster protection are enhanced.

Description

technical field [0001] The invention relates to the field of railway communication equipment, in particular to a railway disaster prevention and early warning information transmission system based on cell broadcast short messages. Background technique [0002] In recent years, as my country's high-speed railway transportation has entered a period of rapid development, my country has built and put into operation a number of passenger dedicated lines and high-speed railways with a design speed of 200 kilometers per hour, such as the Beijing-Shanghai Express Line, Zhengxi Line, Wuhan-Guangzhou Passenger Dedicated Line, etc. Effectively promote the steady development of my country's economy and society. [0003] In order to ensure the safe operation of trains, the railway department has built a railway disaster prevention and safety monitoring system, which is composed of a wind monitoring subsystem, a rainfall monitoring subsystem, a foreign object intrusion monitoring subsystem...

AI Technical Summary

Problems solved by technology

The problem with this method is that it takes time for the dispatcher to respond to the disaster alarm information, and if there are many disasters in the dispatching section, it will take longer and may miss the best time to take measures, resulting in failure Properly prepare for the impact of disasters
