Underground personnel positioning system for mine safety

Abstract

The invention discloses an underground personnel positioning system for mine safety. The underground personnel positioning system comprises a bracelet, a geomagnetic sensor disposed in the bracelet, a three-dimensional attitude sensor and an intelligent control terminal which achieves the wireless communication with the bracelet. The intelligent control terminal is used for driving a corresponding person model to move in a constructed mine three-dimensional model according to received data acquired by the three-dimensional attitude sensor, the position of the underground person is calculated according to the data acquired by the geomagnetic sensor and the three-dimensional attitude sensor, and the underground personnel distribution and the number of personnel are accurately metered; and meanwhile, when accidental communication interruption occurs, the position of the person model at a certain time point can be obtained in a script playback mode, so that the search and rescue range is reduced. A mine three-dimensional model is constructed based on a design drawing of a mine, and a corresponding figure model is driven to move in the constructed mine three-dimensional model according to received data acquired by the three-dimensional attitude sensor, so that the position visualization of mine personnel is realized.

Description

technical field [0001] The invention relates to the technical field of mine safety, in particular to an underground personnel positioning system for mine safety. Background technique [0002] As the country pays more and more attention to the safety production of coal mines, the conventional requirements of coal mine production enterprises have also increased. At present, there are generally problems in the management of personnel entering the mine underground, especially in the coal mining face, and the time for personnel entering and leaving the mine is not fixed. , non-centralized, and highly dispersed, causing great difficulties for the mine to accurately grasp the situation of personnel entering and leaving the mine, resulting in the difficulty of timely and accurately uploading and distributing the information above and below the mine, and it is difficult for the above-ground personnel to grasp the dynamic distribution and operating conditions of underground personnel i...
