Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0030] see figure 1 , a tunnel positioning system based on ZigBee. According to the tunnel positioning requirements, it is divided into the first positioning area and the second positioning area. Mainly for personnel and vehicle positioning. A base station is placed at an interval of 150m in this area, and the lateral distance between two adjacent reference nodes is 20-30m. The positioning nodes are placed on the helmets of the construction workers and on the top of the vehicle. The positioning accuracy of this area can reach 0.2m to 0.3m. The second positioning area is the construction area within the tunnel face. This area is the main area of ​​construction. The construction personnel are dense and the risk factor is high. Therefore, the horizontal distance between two adjacent reference nodes in this area is 5-10m, and the areas on both sides of the tunnel are arr...

Abstract

The invention discloses a tunnel positioning system and a tunnel positioning method based on ZigBee. The system comprises positioning nodes arranged on tunnel constructors and construction vehicles, and reference nodes arranged in the tunnel for collecting the information of the positioning nodes, wherein the output ends of the reference nodes are connected with a ZigBee gateway base station, and the output end of the ZigBee gateway base station is connected with a monitoring center via a signal conversion module. According to tunnel positioning system and method based on ZigBee, the constructors in the tunnel can be comprehensively, timely and accurately positioned, thus the security of the constructors can be ensured.

Description

technical field [0001] The invention relates to the technical field of wireless positioning, in particular to a ZigBee-based tunnel positioning system and method. Background technique [0002] With the increasing strength of the country's economic strength and the needs of social development, more and more tunnels and underground projects have been developed. At present, my country has become the country with the most tunnels, the most complex and the fastest development in the world. While these projects have brought great convenience to people, they have also brought greater construction risks. For the builders and managers of the projects, it means that the risk factor of safe production is getting higher and higher, and the safety management The pressure is mounting. At present, the technology that specifically solves the safety problem of tunnel personnel is still developing slowly in China, especially the positioning of personnel during tunnel construction is the top ...
