Abstract

The invention discloses a control system and a control method for controlling a brake cylinder of a large-size road maintenance machinery maintaining vehicle. The control system comprises a brake cylinder closed-loop control part, a backup brake control part and an assistant brake control part. A closed-loop control mode can be performed on the brake cylinder by the control system and the controlmethod, so that the control precision on the pressure of the brake cylinder is greatly improved; a backup control mode can be performed on the brake cylinder, so that the reliability of a metro engineering maintaining vehicle is improved; and an assistant brake mode can be performed on the brake cylinder, so that brake action can be generated within a short time under the conditions of emergency and distributing valve failure, and the safety of the large-size road maintenance machinery maintaining vehicle can be improved.

Description

technical field [0001] The invention mainly relates to the field of brake control systems in railway engineering maintenance vehicles, in particular to a control method for a brake cylinder of a brake system of a maintenance vehicle for large-scale road maintenance machinery. Background technique [0002] At present, large-scale road maintenance machinery maintenance vehicles mainly use air brakes, which have insurmountable shortcomings, such as difficult expansion of functions, slow response to control commands, resulting in inconsistent pressure of locomotive brake cylinders (poor synchronization), pipeline It is difficult to arrange a lot of equipment on the whole vehicle and has a high failure rate. [0003] With the development of modern railway technology, the maintenance vehicles of large-scale road maintenance machinery are getting longer and longer, and the requirements for control accuracy and control safety are getting higher and higher. The brake cylinder module...
