Abstract

The invention discloses a vehicle speed measuring system of a hinged type self-discharging mine car. The vehicle speed measuring system comprises a ground speed measuring radar and a vehicle speed calculating module. The ground speed measuring radar is mounted on a head chassis of a mine car to be measured; the ground velocity measurement radar is used for sending an electric wave signal with a preset frequency to the ground, receiving an echo signal and outputting a frequency value of the echo signal; the vehicle speed calculation module is used for calculating the real-time vehicle speed of the mine car to be measured according to the frequency values of the echo signals at the adjacent moments; according to the method, the frequency values of the echo signals at the adjacent moments are calculated, and the real-time speed of the mine car to be measured is obtained; data acquisition is convenient and stable, and the processing process is simple and reliable; the calculation process is simple in logic, and the obtained speed result is high in precision, stable and reliable; meanwhile, the original mechanical structure of the mine car is prevented from being greatly changed, the system is easy to install, and the installation position selection difficulty is small.

Description

technical field [0001] The invention belongs to the technical field of unmanned driving, and in particular relates to a vehicle speed measurement system and method of an articulated dump mining truck. Background technique [0002] At present, ore transportation in domestic ore mining is mostly completed by manned mining trucks; due to the complex and harsh natural environment of mining sites, transportation roads, continuous operations and other conditions, the working environment of transportation drivers is very unfriendly, which is not conducive to drivers. It is a general trend to use unmanned mining trucks instead of human drivers to complete ore transportation tasks, which is conducive to improving the working environment of drivers, improving transportation efficiency, and enhancing the safe operation of mines Management, only a small number of drivers are required to conduct remote monitoring and emergency treatment of vehicles indoors, and the unmanned transportatio...
