The Design Of Automaticl Detecting System For Locomotive Hunting

Hunting movement is a movement similar to the movement of the snake in the process of locomotive running,which seriously affects the stability of locomotive movement and the safety of operation.How to effectively detect the locomotive has a snake-like movement,to avoid locomotive accident,to protect the safe operation of the locomotive is of great significance.This paper analyzes the mechanism of the locomotive to produce the serpentine movement,establishes the movement model of the locomotive wheel pair,and studies the physical parameters of locomotive hunting movement.On this basis,a locomotive hunting motion detection method based on ranging.The locomotive hunting motion automatic detection system is designed and designed,and the automatic detection system of locomotive hunting movement is debugged.The results of the testing show that the locomotive hunting can be detected by detecting the lateral offset of the locomotive wheel.Locomotive hunting motion automatic detection system design: through the installation of the track in the edge of the high precision laser ranging sensor to achieve the lateral offset detection,that is,laser ranging method.Hardware control processor selection C8051F120 microcontroller,C8051F120 single-chip laser sensor data acquisition and equipment control.PC software to read the data collected by the microcontroller to complete the data analysis,data processing and test results show.Based on the C # language,the monitoring software of locomotive hunting motion automatic detection system is prepared.The monitoring software provides a graphical interface and has a good human-computer interaction interface.The monitoring software implements automatic reading of data while providing calibration functions.The monitoring software uses the vehicle number interface provided by the vehicle number system to identify the locomotive number,realize the correlation between the detection data and the detection locomotive number.Based on ThinkPHP framework,the data management software of locomotive hunting motion automatic detection system is designed.The data management software is designed with rich human-computer interaction interface,including permission control,historical data view,detection result check and alarm threshold setting.Locomotive hunting movement automatic detection system in the country a locomotive section completed the installation and commissioning work,the test results show that the system can accurately detect the locomotive hunting movement of the situation,the user's high praise.
