Abstract

The invention provides an online real-time online monitoring system, method and device for undesirable emergency braking of a train, and relates to the technical field of monitoring of railway passenger car braking systems. A train pipe pressure sensor collects train pipe pressure data of a carriage where the train pipe pressure sensor is located in real time; a brake cylinder pressure sensor collects brake cylinder pressure data of a carriage where the brake cylinder pressure sensor is located in real time; online real-time online monitoring hosts of undesirable emergency braking of the train arranged in the carriages determine a train pipe decompression rate in real time according to the train pipe pressure data, determines emergency braking of the carriages of the train when the train pipe decompression rate is greater than a preset decompression rate and when the brake cylinder pressure data is greater than a preset pressure threshold, and sends an emergency braking moment of the present carriage to a train level TCDS host; and the train level TCDS host sorts and judges the emergency braking moments of the carriages, locates the carriage generating the undesirable emergency braking at the earliest time and broadcasts an alarm to the entire train.

Description

technical field [0001] The invention relates to the technical field of railway passenger car braking system monitoring, in particular to a vehicle-mounted real-time on-line monitoring system, method and device for accidental emergency braking of trains. Background technique [0002] At present, train braking methods are generally divided into two types: "common braking" and "emergency braking". Braking applied to bring a train to a stop as quickly as possible. At present, a large number of 25G, 25K and 25T normal-speed passenger trains are running in the domestic railway system. These trains generally use automatic air brakes equipped with 104 or F8 air distribution valves. They are designed according to the emergency braking sensitivity of the brakes. When the decompression rate reaches 70-80kPa / s, the train brakes suddenly. However, during the operation of passenger trains, accidental emergency braking by non-drivers often occurs: for example, during the operation of the...
