Problems solved by technology

At present, the vehicle-mounted seismic device only uses a single module to receive earthquake emergency response information. If the GSM-R communication unit in the vehicle-mounted device is abnormal, the vehicle-mounted seismic device cannot receive earthquake emergency response information, and thus cannot work normally.
[0006] 2. The problem is handled in a single way
There is a single way to deal with failures and lack of flexibility

Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] The system block diagram of the wireless communication part of the vehicle-mounted earthquake emergency disposal device is as follows: figure 1 As shown, the earthquake early warning information is converted by the central system of the road bureau into emergency disposal information and sent through the GSM-R system. The main GSM-R communication unit of the vehicle-mounted earthquake emergency disposal device receives the vehicle-mounted ear...

Abstract

The invention discloses a vehicle-mounted earthquake emergency disposal device of redundant GSM-R communication units. The device is characterized by comprising an antenna, a vehicle-mounted earthquake mainframe and a vehicle-mounted earthquake terminal which are connected in sequence, wherein the vehicle-mounted earthquake mainframe comprises the primary and standby GSM-R communication units arranged in a redundant mode, a brake control unit and a power module; all units in the vehicle-mounted earthquake mainframe send heartbeat information to the vehicle-mounted earthquake terminal in the fixed cycle, and the working states of all the units are monitored by the vehicle-mounted earthquake terminal in real time; during normal working, the primary GSM-R communication unit is responsible for performing data communication with a railway administration center system, and the standby GSM-R communication unit only automatically performs GPRS attachment; when the vehicle-mounted earthquake terminal monitors that the primary GSM-R communication unit state is abnormal, or the primary GSM-R communication unit and the railway administration center system have transmission failure, the vehicle-mounted earthquake terminal is used for indicating to perform switching of the primary and standby GSM-R communication units. By means of the device, the reliability, real time and stability of equipment can be improved, and it is guaranteed that a train can run normally and stably.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a vehicle-mounted earthquake emergency treatment device with a redundant GSM-R communication unit. Background technique [0002] At present, the vehicle-mounted earthquake emergency response device (vehicle-mounted seismic device) receives the earthquake emergency response information sent by the earthquake early warning system through GPRS (General Packet Radio Service), and takes corresponding emergency response measures according to the received alarm level. . [0003] The shortcomings of the current vehicle-mounted seismic device receiving emergency information are as follows: [0004] 1. Reliability issues. [0005] The GSM-R (Global System for Mobile Communications–Railway) communication unit of the vehicle-mounted seismic device receives earthquake emergency response information through GPRS, and transmits the received alarm information to other functional units of ...
