Embodiment Construction

[0056] In order to make the content and advantages of the technical solution of the present invention more clear, the underground personnel positioning system and method of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0057] The underground personnel locating system and method of the present invention are a kind of underground personnel locating system and method based on the wireless sensor network. A high-precision positioning method based on a pattern matching method, and an underground personnel positioning system based on a wireless sensor network (Wireless Sensor Network, WSN) combined with the method. The realization of the positioning method is divided into two stages: the first is the training stage, using the training node whose own position coordinates are known to cooperate with the beacon node to generate pattern data including the own position coordinates and the block number, the beacon node numb...

Abstract

The invention discloses a system and a method for positioning underground personnel in a coal mine. The system comprises a ground monitoring center arranged aboveground, a transmission base state arranged underground, a plurality of gateway nodes, an optical fiber, a bus, a plurality of wireless beacon nodes and a plurality of mobile nodes, wherein the system is intrinsically safe when applied to underground equipment. The method is a positioning method based on mode matching and comprises the steps of: dividing a roadway into different blocks according to a roadway structure and the signal coverage area of the beacon nodes, distributing the beacon nodes in each block according to a same manner, generating a positioning mode database on the ground monitoring center through training the nodes in a training state, sending a positioning mode to the ground monitoring center by the mobile nodes according to the positioning signals of the received beacon nodes in a positioning stage, matching a mode generated by training the nodes in the database to find out a proximate mode, thereby realizing accurate positioning. The system and the method for positioning the underground personnel are high imprecision, low in cost and low in energy consumption, and the system is simple in equipment structure.

Description

technical field [0001] The invention relates to the field of underground safety monitoring of coal mines, in particular to an underground personnel positioning system and method based on a wireless sensor network. Background technique [0002] Coal is the main energy source of our country, but for many years, the working environment of coal mines is harsh, the geological environment is complex, and there are always hidden dangers of disasters such as the escape of various harmful gases and unknown water bodies. The low quality has led to the continuous occurrence of vicious accidents in various mines, and the life safety of underground workers has been seriously threatened. With the continuous advancement of science and technology, people have deployed a variety of detection systems and monitoring systems underground in order to know the location of underground workers, facilitate timely rescue work and management scheduling in daily production when mine disasters occur. ...
