Problems solved by technology
The existing technical solutions are mainly analog telephone systems, including both wired systems and wireless systems. The wiring of wired analog telephone systems is complicated, and voice communication can only be carried out in wells and underground in places where telephones are arranged; wireless telephone systems all use GSM or PHS system, the cost is very high and manual maintenance is very difficult
In addition, the current personnel positioning system and voice communication system are independent systems, and data cannot be shared

The invention provides a personnel positioning and wireless voice communication multifunctional system for a mine. The personnel positioning and wireless voice communication multifunctional system for the mine comprises a ground monitoring system located in a control room, underground wireless base stations widely distributed in mine laneways, and multifunctional devices carried by personnel or vehicles. The ground monitoring system and the underground wireless base stations are connected through a CAN bus, the underground wireless base stations are connected through the CAN bus, the underground wireless base stations and the multifunctional devices are in wireless communication through a ZigBee protocol. Each underground wireless base station has a unique and fixed address code, and each multifunctional device has a fixed and unique device code. The personnel positioning and wireless voice communication multifunctional system for the mine organically combines a personnel positioning system and a voice communication system, the adopted wireless base stations and the multifunctional devices are simple in structure, and are low in power consumption and cost, and the personnel positioning and wireless voice communication multifunctional system for the mine can simultaneously achieve the functions of underground personnel accurate positioning and real-time voice communication.
Description
technical field [0001] The invention relates to the field of mine wireless signal transmission, in particular to a multifunctional system for underground personnel based on Ethernet communication. Background technique [0002] my country is the world's largest coal-producing country, with nearly 30,000 coal mines, including more than 500 large and medium-sized coal mines, more than 20,000 small coal mines, and more than 1 million underground workers. In recent years, dangerous mine accidents have occurred frequently, and the death toll in coal mine accidents is four times that of other major coal mining countries in the world. With the continuous increase of demand for coal mines, coal mine accidents in my country have been on the rise in recent years, and the safety situation of coal mines is worrying. When analyzing the major accidents that occurred in several coal mines recently, it was found that the main reason was that the information communication between the ground ...
