Embodiment 1

[0045] see Figure 1-Figure 5 A parking brake control system for a rail transit vehicle includes a parking control circuit, a parking loop and a state feedback circuit. The parking control circuit further includes a parking application control circuit and a parking mitigation control circuit.

[0046] Such as figure 1As shown, the parking application control circuit includes a first parking application switch located in the power vehicle, a first relay J11, a first parking unit, a second relay J12 located in the trailer, a second parking unit, and a control vehicle. The second parking application switch, the third relay J13, the fourth relay J14 and the third parking unit inside.

[0047] The coil of the first relay J11, the coil of the second relay J12, the coil of the third relay J13, and the coil of the fourth relay J14 are connected in parallel.

[0048] The first parking application switch is connected in series with the coil of the first relay J11, and the second park...

Embodiment 2

[0106] This embodiment provides a rail transit vehicle, including a power vehicle, a trailer and a control vehicle. This embodiment takes 1 power vehicle + 1 trailer + 1 control vehicle as an example. The actual car group formation may be 1 power car + 7 trailers + 1 control car, 1 power car + 18 trailers + 1 power car, 1 power car + 7 trailers + 1 control car + 1 Control car + 7 trailers + 1 power car, etc.

[0107] The rail transit vehicle in this embodiment is equipped with the rail transit vehicle parking brake control system in Embodiment 1.

Embodiment 3

[0109] This embodiment provides a parking brake control method for a rail transit vehicle, which is used to control the parking brake system of the power-concentrated EMU in Embodiment 1, and the method includes:

[0110] When the power car receives the parking application command, the first parking application switch is closed, and the feedback power car command state is applied; when the power car receives the parking relief command, the first parking release switch is closed, and the feedback power car command state is relief;

[0111] When the control car receives the parking application command, the second parking application switch is closed, and the command status of the feedback control car is marked as applied; when the control car receives the parking release command, the second parking release switch is closed, and the feedback control car command status is marked as ease;

[0112] When the contacts of the tenth relay and the eleventh relay are both disconnected, th...

Abstract

The invention discloses a rail transit vehicle and a parking brake control system and method thereof. The rail transit vehicle comprises a first parking applying switch, a first relay and a first parking unit which are arranged in a motor vehicle, a second relay and a second parking unit arranged in the trailer, and a second parking applying switch, a third relay, a fourth relay and a third parking unit arranged in a control vehicle, and a central control unit. Due to the adoption of the technical scheme, compared with the prior art, the rail transit vehicle can safely and effectively control and monitor the parking of the vehicle group, and guides a driver to deal with a parking fault in emergency.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit vehicle and its parking brake control system and method. Background technique [0002] In recent years, with the development of EMU technology, power-concentrated EMUs have been gradually popularized in China due to their advantages of flexible marshalling, low manufacturing, operation, and maintenance costs, and high operating speed. All the power cars, trailers and control cars in the power centralized EMUs use electronically controlled parking modules. However, abnormal parking may cause wheel scratches, and abnormal parking relief may cause the car group to slide on the ramp, which seriously affects safe operation. Therefore, how to safely and effectively control and monitor the parking of the vehicle group and guide the driver to deal with parking failures in an emergency is a technical problem that those skilled in the art need to solve at present. Con...
