Personnel positioning method and positioning system applied to tunnel under construction

Abstract

The invention provides a personnel positioning method and positioning system applied to a tunnel under construction. The method comprises the following steps: pre-storing installation position information, installation height information and fixed spacing information of a first base station and a second base station, wherein the tunnel personnel wear positioning tags; respectively arranging the first base station and the second base station on a second lining trolley of a tunnel under construction for detecting relative distances between the base stations and tunnel personnel respectively; and obtaining the relative distance detected by the first base station and the second base station, and calculating the position information of the tunnel personnel in combination with the pre-stored parameters. According to the method, real and accurate positioning and implementation of tunnel safety construction deployment in a real sense are realized, the most objective real rescue data are provided for rescue work after disasters, and the method plays an important role in tunnel safety construction.

Description

technical field [0001] The invention relates to the technical field of tunnels under construction, in particular to a personnel positioning method and a positioning system applied to tunnels under construction. Background technique [0002] At present, the modern means of expressway construction are getting better and better, but the construction environment of expressway tunnels is still harsh and harsh, and the risk factor in the tunnel excavation area is still high, especially in the "face" that is most prone to collapse. There are a large number of workers in the country, and major and extraordinarily large collapse safety accidents occur every year in construction projects at home and abroad. However, the existing supporting technologies and accident rescue programs only have the function of attendance statistics and cannot meet the needs of actual production and construction. , in the actual construction process, the design of the positioning base station is mostly the...

[0002] At present, the modern means of expressway construction are improving more and more, but the construction environment of expressway tunnels is still harsh and harsh, and the work risk factor in the tunnel excavation area is still high, especially in the "face" that is most prone to collapse. There are a large number of workers in the country, and major and extraordinarily large collapse safety accidents occur every year in construction projects at home and abroad. However, the existing supporting technology and accident rescue plan only have the function of attendance statistics, which cannot meet the needs of actual production and construction. , in the actual construction process, the design of the positioning base station is mostly the traditional "inside the base station" positioning mode (similar to the satellite triangulation positioning method, and there is no satellite signal in the tunnel), which cannot meet the environmental needs of the on-site construction. , it is impossible to really locate the specific location of the buried staff
