Embodiment 1

[0040] see figure 1 , which is a schematic diagram of a fire-free return device for a rail vehicle provided in Embodiment 1 of the present application.

[0041] The return device described in the embodiment of the present application is arranged on the returned vehicle, and the train pipe of the returned vehicle is connected with the train pipe of the rescue locomotive.

[0042] The loopback device 100 includes: a pressure sensor 101 and an electronic control unit 102 .

[0043] The pressure sensor 101 is used to detect the pressure of the train pipe of the returned vehicle, because the train pipe of the returned vehicle is connected to the train pipe of the rescue locomotive, so the pressure sensor 101 simultaneously detects the train pipe of the rescue locomotive tube pressure.

[0044] When the rescue locomotive brakes, the train pipe pressure decreases, and the pressure sensor 101 detects the change of the train pipe pressure in time, converts the decompression amount of...

Embodiment 2

[0052] The process of sending the brake level to the brake controller by the electronic control unit will be described in detail below in conjunction with the accompanying drawings.

[0053] see figure 2 , which is a schematic diagram of the braking control of the no-fire return device for rail vehicles provided in Embodiment 2 of the present application.

[0054] Such as figure 2 As shown, the rescue train is connected to the train pipe of the returned vehicle and the main air pipe, and the returned vehicle is equipped with a return device 100. The returned vehicle may have multiple carriages, which is not limited in this application. figure 2 An example of a returned vehicle with two carriages is given.

[0055] Each compartment of the returned vehicle is equipped with a brake controller 103, and the electronic control unit of the return device 100 sends the brake level to the brake controller on each compartment through three transmission lines, and the three transmiss...

Embodiment 3

[0065] During the actual fire-free return process, the returned vehicle may have special circumstances such as abnormal disconnection of the safety loop, accidental application of parking, or low total wind pressure, which may lead to automatic emergency braking. In order to avoid the normal traction of the rescue locomotive, the returned vehicle In the case of braking, the embodiment of the present application also provides another fire-free return device for rail vehicles, which will be described in detail below with reference to the accompanying drawings.

[0066] see image 3 , which is a schematic diagram of another fire-free return device for rail vehicles provided in Embodiment 3 of the present application.

[0067] see also Figure 4 , which is a schematic diagram of the braking control of the no-fire return device for rail vehicles provided in Embodiment 3 of the present application.

[0068] Another rail vehicle no-fire return device 300 provided in the embodiment ...

Abstract

The invention discloses a railway vehicle fireless returning device which is arranged on a returned vehicle and comprises a pressure sensor and an electronic control unit. A train pipe of the returnedvehicle is communicated with a train pipe of a rescue locomotive; the pressure sensor is used for detecting the pressure of the train pipe of the returned vehicle, converting the pressure reduction amount into an electric signal and sending the electric signal to the electronic control unit; the electronic control unit is used for judging the braking level of the rescue locomotive according to the electric signal and sending the braking level to a braking controller of each compartment of the returned vehicle through three transmission lines; and therefore, the brake controller of each compartment brakes according to the braking level. By means of the railway vehicle fireless returning device, wiring can be simplified, the operation difficulty can be lowered, and the railway vehicle fireless returning device has high practicability. The invention further discloses a railway vehicle fireless returning vehicle and method.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a rail vehicle non-fire return device, vehicle and method. Background technique [0002] With the continuous development and progress of society and technology, rail transit is becoming more and more popular. [0003] Rail vehicles are usually equipped with a rescue / return device. Return means that after the vehicle is manufactured, it is returned to the user's site by the locomotive after the test on the track. Rescue means that the vehicle has been delivered for operation, but it breaks down during operation and needs to be towed away. That is, whether it is rescue or return, it only means that the working scene of the vehicle is different. When the vehicle is returned, the return device on the vehicle controls the vehicle to brake. [0004] At present, the loopback device is usually divided into two types. One is portable. Although the device is easy to carry, it ne...
