Embodiment approach 1

[0015] Such as figure 1 As shown, a train brake online monitoring system includes a pressure monitoring unit, a brake monitoring host and a data recorder.

[0016] The pressure monitoring unit includes: a brake pipe pressure monitoring unit, a brake cylinder pressure monitoring unit, an auxiliary air cylinder pressure monitoring unit, a main air pipe pressure monitoring unit; the brake pipe pressure monitoring unit, brake cylinder pressure monitoring unit , the auxiliary air cylinder pressure monitoring unit, and the main air duct pressure monitoring unit are located at the bottom of the first car and the last car, and are used to monitor the pressure of the brake pipe, brake cylinder, auxiliary air cylinder, and main air duct of the first car and the last car ; The brake pipe pressure monitoring unit, the brake cylinder pressure monitoring unit, and the auxiliary air cylinder pressure monitoring unit are arranged at the bottom of each intermediate car, and are used to monitor...

Embodiment approach 2

[0028] The difference from Embodiment 1 is that: the brake pipe pressure monitoring unit, the brake cylinder pressure monitoring unit, and the auxiliary air cylinder pressure monitoring unit are all a check valve and a sensor; the main air pipe pressure monitoring unit includes The box body and the one-way valve and pressure sensor arranged in the box body; the brake pipe pressure monitoring unit, the brake cylinder pressure monitoring unit, and the auxiliary air cylinder pressure monitoring unit are integrally formed through the air circuit board; the air circuit board is equipped with Opening; the opening position and size of the opening are the same as those of the main valve and the intermediate body; a gasket is provided between the air circuit board and the main valve; the brake pipes, brake cylinders and auxiliary air cylinders of each vehicle The holes in the air circuit board are sealed and connected with the brake pipe pressure monitoring unit, brake cylinder pressure...

Abstract

The invention discloses a train brake online monitoring system which comprises a pressure monitoring unit, brake monitoring hosts and a data recorder. The pressure monitoring unit monitors pressure of a brake pipe, a brake cylinder, an auxiliary air cylinder and a main air pipe. The brake monitoring hosts collects and processes in real time pressure data monitored by the pressure monitoring unit; the brake monitoring hosts and the data recorder transmit data through a train broadcast line; the brake monitoring hosts perform data transmission interaction through the train broadcast line; the data recorder receives and processes data sent by each brake monitoring host; and the data recorder feeds data in the train running process back to a ground control chamber or other service terminals through a GPRS module and / or a TCDS interface. After the scheme is adopted, faults of a brake system are monitored in an online mode in real time, and important potential safety hazards during driving are solved.

Description

technical field [0001] The invention relates to the technical field of train brakes, in particular to an online monitoring system for train brakes. Background technique [0002] On the one hand, the braking system of the railway train is to slow down or stop the train under any circumstances to ensure the safety of the train; on the other hand, it is also an important means to increase the running speed of the train and increase the traction weight, that is, to improve the railway transportation capacity. The braking force generated by the train braking system is a human-induced resistance that can be controlled and adjusted by the driver. It is an external force that prevents the train from running due to the wheel-rail adhesion generated by the locomotive and vehicle braking devices. However, train brake system failures often occur during driving. With the increase of train speed, brake system failure has become a major hidden danger to the safety of trains. [0003] Comm...
