Emergent train accident monitoring vehicle-mounted device

Abstract

The invention discloses an emergent train accident monitoring vehicle-mounted device which comprises a three-point data acquisition assembly, a single-point data acquisition assembly, a plug and a monitoring vehicle-mounted module, wherein the three-point data acquisition assembly is mounted on a three-point data acquisition base; the single-point data acquisition assembly is mounted on a single-point data acquisition base; the plug is used for plugging a process hole of the three-point data acquisition assembly and the single-point data acquisition assembly; the monitoring vehicle-mounted module is used for collecting data acquired by the single-point data acquisition assembly and the three-point data acquisition assembly. By adoption of the data acquisition assemblies, pressure change situations of key points in the braking and releasing process of vehicle air braking can be acquired in real time, and the data can be further received by ground reading devices arranged along a railway and are uploaded to a network, so that reliable real-time data for checking accidental brake trains, trains in poor operation situations and accidental emergent activated trains can be provided for users, potential problems which may happen in the operation process of trains can be effectively avoided, and the vehicle operation security can be improved.

Description

technical field [0001] The invention belongs to the technical field of railway vehicles, in particular to an on-board device for emergency monitoring of train accidents. Background technique [0002] None of the existing train air brake systems are equipped with a device for collecting the pressure changes at key points during the braking and mitigation process of the vehicle's air brake, resulting in the inability to automatically search for unexpectedly braked vehicles in real time during vehicle operation, and to alleviate problems. Vehicle and train accident emergency induced vehicle. For vehicles with the above problems, the existing method is to test the pressure changes at key points during the braking and mitigation process of the vehicle's air brake in the laboratory after removing the vehicle's brake valve to determine whether the vehicle has corresponding However, it is impossible to conduct real-time monitoring of the vehicle in the running process, so that ther...

Problems solved by technology

[0002] None of the existing train air brake systems is equipped with a device for collecting pressure changes at key points during the braking and release process of the vehicle air brake, resulting in the inability to automatically find the accidental braking vehicle in real time during vehicle operation and alleviate the failure. Vehicle and train accident emergency induction vehicle

For vehicles with the above problems, after the vehicle brake valve is removed, the pressure changes at key points of the vehicle's air brake during braking and release are tested in the laboratory to determine whether the vehicle has corresponding problems. problems, and it is impossible to monitor the vehicles in the process of operation in real time, so that there are certain safety hazards in the operation of vehicles.
