Abstract

The invention provides a maintenance machinery work vehicle operation detection system, which comprises a vehicle-mounted satellite positioning device, a positioning base station, a central resolving server and track car operation control equipment. Train position information obtained through the vehicle-mounted satellite positioning device and a three-dimensional position coordinate value obtained through calculus of differences are sent to the track car operation control equipment, and information such as reversing and operation speed of a maintenance machinery work vehicle is further obtained. The system can transmit high-accurate, all-day and all-weather navigation and positioning signals, so that the positioning accuracy is improved; and in addition, through real-time difference calculation of positioning data, the large-scale maintenance machinery work vehicle can be continuously, reliably and accurately positioned in real time, so that a better decision can be made in line set, emergency event response, track and other dependent events.

Description

technical field [0001] The invention relates to a detection system, in particular to a detection system for the running of a road maintenance machine operating vehicle. Background technique [0002] Under the current situation of railway safety, speed and heavy load, large-scale track maintenance machinery maintenance has become a necessary means of railway line maintenance after speed increase, and its position in line maintenance is becoming more and more important. Therefore, the safety of the operation system of the large-scale road maintenance machinery operating vehicle affects the maintenance efficiency of the section road section to a certain extent. [0003] At present, the speed measurement methods of large-scale road maintenance machines are mainly two speed measurement methods: pulse sensor speed measurement and Doppler radar speed measurement. In the pulse sensor speed measurement, the electric pulses of the speed sensor of the large-scale road maintenance mach...
