Grade control method and control equipment for railway vehicle and railway vehicle

Abstract

The invention provides a grade control method and control equipment for a railway vehicle and the railway vehicle. The grade control method provided by the invention comprises the following steps: ananalog signal output by a driver controller is sampled to obtain a sampling value, wherein the sampling amplitude range of the sampling comprises a plurality of first intervals and a plurality of second intervals, the first intervals and the second intervals are arranged at intervals, and each first interval corresponds to one grade; an interval to which the sampling value belongs is determined; if the sampling value belongs to any first interval, it is determined that the grade of the driver controller is the grade corresponding to the first interval; and if the sampling value belongs to anysecond interval, it is determined that the grade of the driver controller is the grade when the driver controller outputs the analog signal. The safety of the vehicle is improved.

Description

Technical field [0001] The present invention relates to rail transit technology, in particular to a class control method, control equipment and rail vehicle for rail vehicles. Background technique [0002] Driver controllers (referred to as master controllers) are usually installed on the driver’s platform of rail vehicles. The driver of the vehicle controls the forward or backward of the vehicle by adjusting the position of the direction handle on the master controller. The position control vehicle tows or brakes at each level. [0003] When adjusting the level handle of the master controller, the master controller outputs the corresponding analog signal. The analog signal is processed by the sampling device in the control device and then converted into a sampled value. The sampled value is then converted by the control device to another corresponding one. Analog signal. The control device determines the level corresponding to the master controller level handle at this time acco...

Problems solved by technology

[0004] In the process of converting the analog signal to the corresponding level, because the analog signal will be affected by the environment, the acquisition device, and the driver’s human misoperation, the sampling value may change in two adjacent intervals, resulting in the level It will frequently switch between two adjacent levels, which will cause a sudden change in the traction or braking force of the vehicle and affect the safety of the vehicle
