Embodiment Construction
[0033] The control device provided in this embodiment for the railroad transportation of urban rail vehicles is placed in the middle of the aisle near the driver's cab, the air duct of the device is connected with the air duct of the locomotive, and the circuit is connected to the terminal of the train through a wire connector row and relay. Compared with the existing technology, the train tube of the train itself is used, which has a certain connection with other devices on the train, and there is a certain risk; this device uses an independent air duct, which is directly connected to the locomotive and the control device, and the compressed air does not pass through. the train itself.
[0034] The above-mentioned control device is composed of a brake control box, connecting pipelines, electrical circuits and the like. The schematic diagram of the brake control box is shown in figure 2 , consists of microcomputer control unit, pressure sensor, emergency exhaust device, pre...

The invention discloses a control device used for the whole train interposition of mass transit vehicles in railway transportation and a control method thereof. The method comprises the steps: a pressure sensor is firstly adopted to receive pressure signals, speed signals and other digital quantity control signals of train pipes, and can output brake force command signals and other control signals which can be recognized by a brake electronic control unit (BECU) after the inner treatment of a transportation control device. The invention can directly control the brake system of a train, is independent from the other systems of the train, ensures that the brake processes of the mass transit vehicles and railway vehicles are consistent and reduces the brake impact, thus being convenient for being maintained and updated.
Description
technical field [0001] The invention belongs to the technological equipment of urban rail vehicles, and is mainly used for controlling brakes when the urban rail vehicles are assembled and linked to railway transportation. Background technique [0002] Urban rail vehicles are generally transported by road flatbed trucks or railway trains. The control principle of the vehicle transportation device in the past is as follows: figure 1 Shown: Urban rail vehicle train train rail transport is to collect the train tube pressure change by the transport device, and convert the pressure change into an analog electrical signal and transmit it to the vehicle control unit (VCU). The VCU determines the train control system according to the train tube pressure change and give corresponding braking or mitigation instructions for urban rail vehicles. In this mode, the transportation device is equivalent to the role of the vehicle controller. [0003] Since the transportation device of the...
