Problems solved by technology
[0002] my country's coal mine safety accidents occur frequently, and some coal mines cannot provide the number and exact location of underground personnel after mine disasters occur, which seriously affects the rescue work of mine disasters
At present, the data transmission medium of domestic coal mine underground monitoring and monitoring systems is mainly cables, and the transmission method is analog. This monitoring and monitoring system has the following defects: the underground operating environment is harsh, and the cables are easily damaged. Once this happens, it is difficult. Determining the fault point of the system affects the normal use of the system; in addition, the system uses analog data for data transmission and exchange, which has poor anti-interference ability and is prone to false alarms; at present, all kinds of systems put into operation in coal mines cannot provide dynamic positioning of underground personnel and voice communication, the victims cannot be rescued in time

Embodiment Construction
[0018] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0019] A method for real-time monitoring of personnel in mines based on ZigBee network technology, the innovation is that the method includes the following steps:
[0020] a. Arrange tree-like, star-like, mesh-like grids in the underground roadway, each network is composed of a base station 3 and a router 2, the base station is set at the beginning of the network, and routers are set at a certain distance along the network extension direction, Place the locator 4 on the underground operator, the base station, the router, and the locator adopt the IEEE802.15.4 wireless network protocol to realize wireless transmission, and the base station and the control computer 1 on the well surface exchange data through the Ethernet or RS485 communication ...

The invention relates to an under-coal-mine people real-time monitoring method based on a ZigBee network technology. The method includes the steps that networks with tree-shaped, star-shaped and net-shaped structures are arranged in an under-mine roadway; each network is composed of a base station and a router; a positioner is arranged on the body of an under-mine operation person; wireless transmission is achieved among the base stations, the routers and the positioner through an IEEE802.15.4 wireless network protocol; data exchange between the base stations and an above-mine control computer is performed through Ethernet or a RS485 communication protocol; a mathematic relation exists between space distance and RRSI values of radio signals among all nodes of the networks in a specific environment; and then the positioner determines the relative position of a space where the person is located according to the built mathematic relation and the newly measured RRSI values and sends information back to an above-mine computer control system, and therefore real-time monitoring of the under-mine person is achieved.
Description
technical field [0001] The invention belongs to the technical field of coal mine safety, in particular to a real-time monitoring method for underground personnel in a mine based on ZigBee network technology. Background technique [0002] Coal mine safety accidents occur frequently in our country. After some coal mine disasters occur, the number and exact location of underground personnel cannot be provided, which seriously affects the rescue work of mine disasters. At present, the data transmission medium of domestic coal mine underground monitoring and monitoring systems is mainly cables, and the transmission method is analog. This monitoring and monitoring system has the following defects: the underground operating environment is harsh, and the cables are easily damaged. Once this happens, it is difficult. Determining the fault point of the system affects the normal use of the system; in addition, the system uses analog data for data transmission and exchange, which has po...
