Problems solved by technology
If the inspection vehicle controls the brake system of the engineering vehicle through its own brake controller, the brake controller of the engineering vehicle also sends out control commands due to some reasons, such as misoperation, etc., which will inevitably cause The control logic of the brake control unit is confused, the control process is contradictory, etc., which may lead to serious operating accidents

The invention discloses a braking control method of a double-headed marshaling locomotive for engineering detection, comprising the following steps: sending a main control activation signal to a braking control unit of an engineering vehicle, so as to enable a braking controller of a detection vehicle to be effective to an input signal of the braking control unit and meanwhile to enable a braking controller of the engineering vehicle to be ineffective to the input signal of the braking control unit; sending an engineering vehicle braking force regulating signal to the braking control unit, so that the braking control unit regulates a braking force of the engineering vehicle according to the regulating signal. According to the braking control method disclosed by the invention, a main control position of the braking controller of the detection vehicle is determined by means of the function of the main control activation signal, so that the input signal of the braking control unit is only effective to the braking controller of the detection vehicle, the influence of the braking controller on the engineering vehicle is avoided, and therefore the braking control unit is ensured to have a correct control logic. The invention also discloses a braking control system and a double-headed marshaling locomotive for the engineering detection, with the beneficial effects as described.
Description
technical field [0001] The invention relates to the technical field of braking control of rail transit vehicles, in particular to a braking control method for engineering inspection reconnection marshalling locomotives. Background technique [0002] With the development of rail transit technology in China, more and more locomotives have been put into use. [0003] There are many types of locomotives, such as subways, passenger and freight trains, high-speed rails, light rails, etc. These are relatively common locomotives. At the same time, there are also engineering inspection vehicles specially used for maintenance operations on the rail transit. The engineering inspection vehicle (hereinafter referred to as "inspection vehicle") is equipped with rail inspection cabinets, network inspection cabinets and other equipment to test the functions of the track and catenary. There is no separate braking system and traction system on the inspection vehicle, but the cab is equipped ...
