Abstract

The invention discloses a navigation positioning terminal for a mine and a working method. The navigation positioning terminal comprises an MCU control processing module, a CSS radio frequency moduleand antenna, an INS inertial navigation device, a barometric leveling module and a LORA communication module and antenna, wherein the CSS radio frequency module is connected with the MCU control processing module through an SPI bus, the INS inertial navigation device is connected with the MCU control processing module through an SPI bus, the barometric leveling module is connected with the MCU control processing module through the SPI bus, and the LORA communication module is connected with the MCU control processing module through the SPI bus. The navigation positioning terminal for the minecan achieve accurate positioning when used in sites with satellite signal rejection environment such as the mine and an underground pipe network, so that the personal safety of mine workers is guaranteed, and the very important practical significance is achieved.

Description

technical field [0001] The invention belongs to personnel positioning technology in special environmental places such as mines and underground pipe networks, and in particular relates to a navigation and positioning terminal and a working method for mines. technical background [0002] The operating environment of mines and underground pipe networks is harsh, often accompanied by natural disasters such as gas and coal dust explosions, fires, and floods, which seriously threaten the lives of miners. From the analysis of a large number of cases, it can be concluded that the causes of the accidents are common. In addition to the insufficient investment in safety facilities and the low quality of the employees, another important reason is: ineffective management measures for the personnel who go down the well, and inadequate supervision and inspection of personnel. . At present, it is difficult to manage the personnel entering the mine underground, and sometimes the number of p...
