A redundant train passenger emergency braking control device and method

Abstract

The invention discloses a redundant emergency braking control device and method for train passengers. The device includes a first emergency braking control device and a second emergency braking control device, wherein the first emergency braking control device and the second emergency braking control device The two emergency braking control devices work synchronously to generate electrical signals and control the air pressure change of the train tube respectively, and can detect the above two signals at the same time, and perform emergency braking operation processing based on the two signals. It can be seen that the device is provided with two emergency braking control devices, which are mutually redundant, and can overcome the problem of low reliability caused by a single device. Secondly, because the air circuit control device in the second emergency brake control device is to control the air pressure change of the train pipe, it belongs to mechanical pure air control, and its reliability is higher than that of the electric control method. In addition, the redundant emergency braking control method for train passengers provided by the present invention has the same effect as above.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a redundant emergency braking control device and method for train passengers. Background technique [0002] The train mentioned in the present invention can be an ordinary train or an EMU train. In specific implementation, it is mainly used for EMU trains. For the safety of passengers, the EMU is equipped with an emergency brake control device in the passenger compartment. The function of the emergency brake control device is to trigger the emergency brake button on the emergency brake control device when passengers encounter an emergency. The emergency braking control device transmits the trigger signal to the TCMS (Truck Management Control System), and then the TCMS performs emergency braking according to the signal. [0003] In the prior art, the emergency brake control device is usually a purely electronic control device, that is, after the emergency brake button is tri...

AI Technical Summary

Problems solved by technology

Obviously, due to pure electrical signal control, once a single point of failure is encountered, emergency braking cannot be achieved. For example, when the emergency brake button is triggered, the electrical signal cannot be generated or the relevant circuit transmitted to the TCMS is faulty, resulting in the failure of the TCMS to collect To the electrical signal
