Inspection device and method for inspection cycle of coal mine personnel positioning system

Abstract

The invention discloses an inspection device and method for the inspection period of a coal mine personnel positioning system, and belongs to the technical field of inspection of coal mine personnel positioning systems. The inspection device for the inspection cycle of the coal mine personnel positioning system comprises an electromagnetic shielding box and an upper computer, the electromagnetic shielding box is divided into an upper-layer space and a lower-layer space through an electromagnetic shielding partition plate, the electromagnetic shielding partition plate is connected with the electromagnetic shielding box through an electromagnetic lock, a positioning card is arranged in the upper-layer space, and a positioning base station is arranged in the lower-layer space. The upper computer collects the opening and closing state of the electromagnetic lock and obtains the time point when the state of the electromagnetic lock changes, the positioning base station sends the positioning information data of the positioning card to the upper computer, and the upper computer calculates the inspection period according to the time point when the state of the electromagnetic lock changes and the positioning information data of the positioning card and judges whether the inspection period is qualified or not. According to the inspection device and method for the inspection period of the coal mine personnel positioning system, accurate inspection of the inspection period index of the coal mine personnel positioning system can be realized.

Description

technical field [0001] The invention relates to the technical field of inspection of a coal mine personnel positioning system, in particular to an inspection device and method for an inspection cycle of a coal mine personnel positioning system. Background technique [0002] At present, in the process of personnel positioning management in coal mines, the traditional regional positioning system is mostly used. The traditional regional positioning system can only locate the staff in a certain area, but cannot realize the precise positioning of the personnel position. In recent years, with the development of science and technology, the precise positioning system for coal mine personnel based on ultra-wideband (UWB) technology has gradually been applied in coal mines. It can achieve centimeter-level static positioning accuracy for underground personnel, and has gradually replaced traditional regional positioning systems. [0003] The inspection cycle is an important technical in...

Problems solved by technology

[0004] In addition, in the inspection process of the inspection cycle of the existing positioning system, the wireless identification range of the positioning base station has an important relationship with the difference of electronic components, the external environment interference and the performance of the positioning card. Therefore, the wireless identification range of the positioning base station is Uncertain and changing from time to time, it is impossible for multiple positioning cards to enter the identification areas of multiple positioning base stations at the same time, making it very difficult to inspect the inspection cycle
