The invention discloses a wheel flange wear safety control system and method, which solves the problem that the wheel flange wear of a vehicle affects the traffic safety. The method comprises the following steps of lubricating a wheel flange according to a lubricating period and a lubricating frequency, and measuring real-time acceleration information. Performing filter analysis on the acceleration information, when the acceleration information is greater than a first threshold value, performing emergent lubricating, at the same time, calculating the number of times that the acceleration information which is greater than the first threshold value appears, and when the acceleration information is greater than a second threshold value, running in a speed reduction mode. The lubricating period is used for determining the lubricating time under a non-emergent lubricating condition, and the lubricating frequency is used for determining the number of times of lubricating within the lubricating period. The system comprises a lubricating control module for setting the lubricating frequency and the lubricating period, a lubricating system for lubricating, an acceleration sensor for measuring and sending the acceleration information, and a vehicle speed control system for performing running in a speed reduction mode, wherein the acceleration sensor is mounted in the lubricating system.
Description
technical field [0001] The present application relates to the field of rail transportation, in particular to a safety control system and method for wheel rim wear. Background technique [0002] As a kind of heavy-duty public transportation, rail transportation is the main direction of research on how to provide passengers with safer transportation, more comfortable riding experience, and reduce the cost of use. The research shows that the rim wear of rail transit products as the steel wheel and rail system is unavoidable when passing through curved lines, and the rim wear will produce sharp whistling noises that damage human hearing. Reducing the friction coefficient of the rim sliding friction area can effectively reduce the rim wear rate and eliminate the sharp whistling noise generated by the rim sliding friction. The running state of the vehicle can be judged by detecting the acceleration on the running part of the rail transit vehicle. When the acceleration is within a...
