Embodiment Construction
[0035] 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.
[0036] 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 and a control method for urban rail vehicle train-hanging railway transportation. Firstly, a pressure sensor receives a train pipe pressure signal, a speed signal and other digital quantity control signals, and passes through the interior of the transportation control device. After processing, the braking force command signal and other control signals that can be recognized by the brake electronic control unit (BECU) can be output. The invention can directly control the train braking system and is independent of other systems of the train, so as to ensure that the braking process of the urban rail vehicle and the railway vehicle is consistent, reduces the braking impact, and is convenient for maintenance and upgrading.
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. [0002] Background technique [0003] 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. [0004] Since the transportation dev...
