Embodiment 1

[0055] Please refer to figure 1 , figure 1 It is a flow chart of a method for detecting a brake main pipe in an embodiment of the present invention, and the method is applied to a detection device. The method includes the following steps:

[0056] S101. When the brake main pipe continuity query command is detected, exhaust a small amount of pressure air at the tail end of the brake main pipe through the exhaust valve.

[0057] In the embodiment of the present invention, the user can operate the buttons, knobs or touch screen on the detection device, so that the detection device detects the user's operation behavior, and based on the operation behavior, it is determined whether to obtain the supervisory connectivity query instruction.

[0058]When the brake main pipe penetration query command is detected, a small amount of pressure air can be discharged instantly at the tail end of the brake main pipe by controlling the exhaust valve. The pressure drops suddenly and causes a...

Embodiment 2

[0072] Corresponding to the first embodiment above, the embodiment of the present invention can also use braking waves to detect the integrity of the train. For details, please refer to figure 2 , on the basis of the first embodiment above, perform the following steps:

[0073] S201. Use the wind pressure sensor located at the rear end of the vehicle to monitor the wind pressure at the rear end of the brake main pipe to obtain a rear end pressure signal.

[0074] In the embodiment of the present invention, in addition to setting a pressure sensor in the brake main pipe at the locomotive end, a pressure sensor may also be provided in the brake main pipe at the rear end of the locomotive. The pressure sensor can monitor the wind pressure at the end of the brake main pipe. In this way, when the exhaust valve is used to discharge a small amount of pressure air at the tail end of the brake main pipe, the wind pressure sensor at the rear end of the vehicle can be used to monitor ...

Embodiment 3

[0108] Corresponding to the above method embodiments, an embodiment of the present invention also provides a brake main pipe detection device. The brake main pipe detection device described below and the brake main pipe detection method described above can be referred to in correspondence.

[0109] see image 3 As shown, the device includes the following modules:

[0110] The exhaust valve control module 101 is configured to use the exhaust valve to discharge a small amount of pressure air at the tail end of the brake main pipe when a brake main pipe permeability query instruction is detected;

[0111] The locomotive end pressure signal acquisition module 102 is used to monitor the locomotive end wind pressure of the brake supervisor by using the wind pressure sensor located at the train locomotive end to obtain the locomotive end pressure signal;

[0112] A braking wave detection module 103, configured to determine whether there is a braking wave signal in the pressure signa...

Abstract

The invention discloses a braking main pipe detection method, device,equipmentand a readable storage medium. The braking main pipe detection method comprises the following steps that when a braking main pipe penetration inquire command is detected, a small amount of pressurized air is discharged at the tail end of the braking main pipe by using an exhaust valve; the wind pressure at the locomotive end of the braking main pipe is monitored by using a wind pressure sensor located at the train locomotive end, and a pressure signal at the locomotive end is obtained; whether a braking wave signal exists in the pressure signal of the locomotive end or not is judged; if yes, the braking main pipe is determined to be penetrated; and if not, the braking main pipe is determined to be not penetrated. According to the braking main pipe detection method, the penetration of the braking main pipe is detected by using the braking wave signal, the advantage of anti-interference is also achieved, and the penetration detection result is more accurate. The invention further discloses a braking main pipe detection device, equipment and a readable storage medium, and corresponding technical effects are achieved.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a method, device, equipment and readable storage medium for detecting a brake main pipe. Background technique [0002] The reliability of the train air brake system directly affects the running safety of the train. The most important condition to ensure the reliability of the train air brake system is: the brake supervisor of the whole train must be kept in a through state during operation. Therefore, in 1988, the Ministry of Railways listed the problem of preventing accidents caused by the closing of the knuckle cocks as a key research project for the safety of the whole road. So far, scientific research units, colleges and some enterprises along the way have successively developed various devices for preventing the dog from closing. Generally speaking, it is a train brake penetration condition monitoring device and a wireless train tail device. [0003] However, these ...
