Abstract
Description
Technical Field
[0001] The present invention belongs to the field of electric locomotive braking, and in particular relates to an electric locomotive braking control system and method based on environmental analysis. Background Art
[0002] An electric locomotive is a locomotive whose wheels are driven by an electric motor. In normal braking mode, an electric locomotive has two braking modes: air braking and electric braking. However, when the main or small brakes or the brake control unit of the electric locomotive malfunction, the operator will switch the electric locomotive from normal braking mode to backup braking mode. However, in the existing technology, when an electric locomotive uses air braking and electric braking at the same time, the magnitude of the air braking force and the electric braking force is difficult to control. When the braking force applied to the electric locomotive is too large, it is easy to cause the electric locomotive to malfunction. The existing technology is unable to comprehensively analyze the data of the brake module and the braking environment data during the braking process, and is unable to accurately identify the operating status of the brake module, which reduces the accuracy and efficiency of the brake function warning. The above problems exist in all existing technologies. For example, Chinese patent application publication number CN103625504A discloses a brake control method and device for an electric locomotive. The electric locomotive includes a controller, a pressure switch connected to the controller via a first interface, and a brake cylinder connected to the pressure switch. The method may include: obtaining a level at the first interface and determining the type of the level. The levels include a first level and a second level. The first level is generated when the brake cylinder pressure detected by the pressure switch is less than a first preset pressure; the second level is generated when the brake cylinder pressure detected by the pressure switch is greater than or equal to the first preset pressure. The first preset pressure serves as a criterion for whether to activate electric braking. When the level is the first level, electric braking is activated; when the level is the second level, electric braking is deactivated. The present invention enables the use of air braking and electric braking in combination while ensuring that power failure does not occur, thereby saving energy. The above patents all have the problems raised by this background technology: the existing technology is unable to comprehensively analyze the data of the brake module and the braking environment data during the braking process, and is unable to accurately identify the operating conditions of the brake module, which reduces the accuracy and efficiency of the brake function warning.
