Problems solved by technology

[0003] In the process of personnel work and vehicle transportation, due to the limitation of the working environment, conventional positioning methods have many limitations such as missing detection of the system, low positioning accuracy, high base station density, or inconvenient carrying of positioning cards. The real-time positioning system for underground personnel and vehicles needs to be improved.

Embodiment Construction

[0019] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0020] Such as figure 1 and 2 , an underground personnel and vehicle positioning system based on LoRa technology, including a server 2, a positioning base station 3, a personnel positioning card 5 carried on a person, and a vehicle positioning card 6 placed on a vehicle.

[0021] The server 2 and each positioning base station 3 are connected to each other through an Ethernet 1 .

[0022] The positioning base station 3 and the personnel positioning card 5 perform two-way communication through the LoRa signal 4, and perform distance measurement through the LoRa signal 4.

[0023] The positioning base station 3 and the vehicle positioning card 6 perform two-way communication through the LoRa signal 4, and perform distance measurement through the LoRa signal 4.

[0024] The positioning base station 3 has a network transceiver function.

[0025] The pers...

Abstract

The invention discloses an underground human-vehicle positioning system based on a LoRa technology. The underground human-vehicle positioning system comprises a server, a positioning base station, a personnel positioning card carried by personnel, and a vehicle positioning card placed on a vehicle, wherein the server is connected with the positioning base stations through the Ethernet, and the positioning base stations are connected with the personnel positioning cards and the vehicle positioning cards through LoRa signals. The LoRa technology relied on by the invention has a good anti-interference characteristic, the missed reading rate of the system is greatly reduced, and the system also has the advantages of wide coverage, low power consumption and the like.

Description

technical field [0001] The invention relates to an underground man-vehicle positioning system. Background technique [0002] Mining is the technology and science of mining mineral resources from the earth's crust and surface. It is an important raw material industry. The mined metal ores are the main raw materials for the smelting industry, and non-metallic ores are important chemical raw materials and building materials. Due to the particularity of the underground operating environment, real-time positioning and statistics of underground workers and vehicles will greatly promote mine production safety and production efficiency. [0003] In the process of personnel work and vehicle transportation, due to the limitation of the working environment, conventional positioning methods have many limitations such as missing detection of the system, low positioning accuracy, high base station density, or inconvenient carrying of positioning cards. The real-time positioning system for...
