Title:
INERTIAL NAVIGATION PRECISION EVALUATION SYSTEM AND EVALUATION METHOD FOR COAL MINING MACHINE, AND MOBILE CARRIER
Document Type and Number:
WIPO Patent Application WO/2024/087473
Kind Code:
A1
Abstract:
The present invention relates to an inertial navigation precision evaluation system and evaluation method for a coal mining machine, and a mobile carrier. The inertial navigation precision evaluation system comprises: a mobile carrier, wherein inertial navigation to be subjected to measurement, an RTK-GNSS mobile station and an electric control box are all arranged on the mobile carrier; a fixed track, which is used for simulating an operation trajectory of a coal mining machine, wherein the mobile carrier can reciprocate along the track between two ends of the track; an RTK-GNSS base station, wherein the RTK-GNSS base station and the RTK-GNSS mobile station match each other to form an RTK-GNSS surveying and mapping system, and the RTK-GNSS base station is arranged in an open scene independently of the mobile carrier and the track; and an upper computer, which is used for receiving and processing first measurement data from the inertial navigation and second measurement data from the RTK-GNSS surveying and mapping system, and evaluating the precision of the inertial navigation. The present invention can realize long-time low-speed repeated tests of inertial navigation, and can simulate the operation condition of the coal mining machine during borehole operation, such that evaluation data is more accurate and reliable.
