The invention discloses a location accuracy assessment method of an underground coal mine personnel location system based on a TOA technique, and belongs to the field of mine monitoring and communication. The accuracy assessment of the system is determined through system static accuracy and system dynamic accuracy. The system static accuracy is determined by a timer time resolution ratio, processor frequency and system errors for achieving time measurement of the TOA in the system. The system dynamic accuracy is determined by a location routing inspection cycle and a displacement speed of a located person. Aimed at a system location technique and equipment physical performance, the method achieves comprehensive assessment for the location accuracy of the underground coal mine personnel location system based on the TOA technique and provides relative guidance for system design.
Description
technical field [0001] The invention relates to a positioning accuracy evaluation method of a coal mine underground personnel positioning system based on the TOA technology, and is particularly applied in the field of mine monitoring and communication. Background technique [0002] The "Notice of the State Administration of Work Safety and the State Coal Mine Safety Supervision Bureau on the Construction and Improvement of the "Six Major Systems" for Underground Coal Mine Safety and Hedging" (An Jian Zongmeizhuang [2010] No. 146) requires the construction and improvement of the coal mine underground personnel positioning system to play The role of the underground personnel positioning system in personnel management and emergency rescue work, "should give priority to products with advanced technology, stable performance, and high positioning accuracy to ensure accurate control of the dynamic distribution of underground personnel and the number of personnel in the mining face."...
