Problems solved by technology

[0004] (1) The derailment detection effect is poor, and when the sensor is directly impacted, there is no unloading structure, which directly leads to damage to the sensor and cannot be judged normally
[0005] (2) The crossbeam of the obstacle detection device is easily damaged by impact, cannot be used for a long time, and is troublesome to replace

Abstract

The invention discloses a contact type obstacle and derailment detection device which comprises a detection execution assembly installed on a vehicle bogie and an obstacle detection host installed in an electrical cabinet in a vehicle, and the detection execution assembly and the obstacle detection host are communicated through a cable. According to the contact type obstacle and derailment detection device, the running state of a locomotive is monitored in real time, the energy of collision between the locomotive and an obstacle (or derailment events) is detected, when the energy of collision between the locomotive and the obstacle exceeds a threshold value (or derailment events) in the running process of the train, an alarm signal is generated and transmitted to an electrical system, and the electrical system disconnects a train braking safety circuit; therefore, the train is braked emergently, and the purpose of reducing loss is achieved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a contact obstacle and a derailment detection device. Background technique [0002] In rail transportation, the obstacle detection device mainly detects objects existing in the track to avoid damage to rail vehicles caused by obstacles. At present, subway stations are mainly judged by using cameras placed above the tracks. However, this solution cannot fully meet the needs, because this solution can only detect obstacles in the monitoring area; in bad weather, if there are obstacles in front of the vehicle , the rail vehicle driver will be difficult to detect, and thus may not be able to avoid obstacles causing damage to the rail vehicle. [0003] As attached to the manual figure 1 As shown in the prior art, the force sensor detection device is installed between the mounting plates to detect the impact force of the obstacle on the detection beam, and the accurate force inf...
