Embodiment Construction
[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0016] Such as figure 1 Described, a coal mine underground personnel positioning method comprises the following steps:
[0017] (1) In the roadway where there are operators in the coal mine, the radio frequency scale cable 1 is laid along the roadway wall. There is a wire 20 in the insulating sheath of the radio frequency scale cable 1, and a plurality of passive radio frequency tags 2 are arranged on the wire 20 at intervals , wherein each passive radio frequency tag 2 has a unique and fixed ID identification code; the passive radio frequency tags 2 inside the radio frequency ruler cable 1 are arranged according to a certain distance, and the size of the arrangement spacing determines the measurement unit and positioning accuracy of the radio frequency ruler cable 1 . The radio frequency ruler cable 1 and the internal passive radio...

The invention discloses a coal mine underground personnel positioning method which comprises the following steps of: laying a radio frequency ruler cable in a roadway in which personnel positioning needs to be realized under a coal mine, taking a radio frequency ruler cable base band as a lead, arranging a plurality of passive radio frequency tags close to the lead at equal distance, enabling the passive radio frequency tags to carry out non-contact type radio frequency identification communication with active ratio frequency tags carried by personnel entering the coal mine, reading an ID (Identification) code and time sequence information of each radio frequency tag in a communication state by a reader, uploading to a ground server through a network and then finishing a personnel positioning function through calculation and analysis and in combination with a mine two-dimensional or three-dimensional mining drawing. Compared with a traditional positioning method, the positioning method has the advantages of high positioning precision, strong interference resistance, low construction cost and the like, is particularly suitable for special environment under the mine coal, can be expanded to be applied to galleries, tunnels, caves and other strip-shaped occasions and can also be applied to other environment in which a wireless positioning manner is limited, and moving objects (personnel, vehicles, goods and materials) need to be accurately positioned in real time.
Description
technical field [0001] The invention relates to the technical field of automatic identification and positioning, in particular to a method for locating underground personnel in coal mines. Background technique [0002] The mine personnel positioning system is one of the six coal mine safety security systems that the national safety supervision department compels to build. The positioning function of the system is extremely important in the daily management of the mine operators, especially in the timely and accurate organization of search and rescue in the event of an accident. effect. The mine personnel positioning system currently used mainly determines the positioning accuracy by the distribution position of the readers, which is usually tens of meters or even hundreds of meters, and the data availability is low. With the continuous extension of coal mine mining depth in my country, the number of high gas and gas outburst mines is increasing, and the safety production of...
