Abstract

The invention relates to a dynamic error measurement system and method for a coal mine underground personnel accurate positioning system, and belongs to the field of coal mine informatization. The system comprises a measuring point detection device with an infrared correlation function, a speed detection device and upper computer platform software installed on a computer. An infrared receiving module, a network communication module and a central processing unit are arranged in the measuring point detection device, the upper computer communicates with the network communication module of the device in a network mode, and clock synchronization between the central processing unit of the device and an upper computer platform is achieved; the device judges whether the equipment passes through a measuring point or not according to the existence of an infrared signal received by the infrared receiving module; and the central processing unit records the time when the tested equipment passes through the test point according to a judgment result of the infrared module, and uploads the time to an upper computer platform through the network communication module. The speed detection device is provided with an infrared receiving module, an analysis processing module and an output control module. Errors caused by manual metering detection can be effectively reduced, and the detection efficiency is improved.

Description

technical field [0001] The invention belongs to the field of coal mine informatization, and relates to a dynamic error measurement system and method of a precise positioning system for underground personnel in a coal mine. Background technique [0002] The document "Safety Technical Requirements for Coal Mine Underground Personnel Positioning System (Trial)" specifies the relevant functions and technical parameters of the coal mine underground personnel precise positioning system. [0003] The dynamic error is required to be no greater than 7.3m@7m / s displacement speed, and 5 test points are required to be selected within the coverage of a single base station during the detection process. The upper computer of the system observes the error between the system positioning measurement coordinates and the real coordinates when passing the test point. [0004] There are two key points to make the test results credible: [0005] The first point is that the time of recording the ...
