Title:
TESTING DEVICE AND TESTING METHOD FOR COAL MINE MOVING TARGET POSITIONING CAPABILITY
Document Type and Number:
WIPO Patent Application WO/2023/151131
Kind Code:
A1
Abstract:
A testing device and testing method for coal mine moving target positioning capability, relating to the technical field of coal mine identification cards. The system comprises a timing unit, a control unit, a laser emitting unit, a laser receiving unit, and a constant-speed locomotion device; a plurality of sets of clock units, laser receivers, and laser emitters serve as test points and are provided near a positioning substation, on two boundaries of a positioning region of the substation, and between the substation and the two boundaries of the positioning region; a positioning identification card is fixed on a positioning vehicle of the constant-speed locomotion device; the positioning identification card is driven by the constant-speed locomotion device to move forward from the outside of the coverage boundary of the substation at a constant speed, and the time of all clock unit is counted to correspond to receiving time recorded by a moving target positioning system server, and a difference between a moving distance of the positioning vehicle to which the positioning identification card is fixed and the position of the timing unit within the same time is calculated and used as a dynamic error evaluation value of moving target positioning capability. According to the system and method, the coal mine moving target positioning capability can be accurately and automatically tested.
