Problems solved by technology

[0003] With the continuous development of urban construction activities, the ground appendages corresponding to the cable tunnel are constantly changing, the original ground reference objects have changed or disappeared, and the changes of the ground appendages have not been updated to the GIS map in time, making it difficult Existing buildings determine the specific location of the underground cable tunnel
[0004] In addition, the cable tunnel is located deep underground. There is no GPS signal or communication signal in the tunnel. Once the inspectors enter the tunnel, they cannot communicate with the personnel on the ground.
[0005] If there is an emergency in the cable tunnel, the management personnel cannot know the specific location and life safety of the inspectors in the tunnel, nor can they excavate and rescue the accident personnel at precise locations, which will increase the workload of the operation and maintenance personnel when inspecting the cable tunnel. risk

Embodiment 1

[0033] In order to locate the personnel in the cable tunnel on the ground, and obtain the latitude and longitude coordinates and latitude and longitude coordinates of the personnel, so that the personnel's positioning does not depend on the fixed attachments on the ground, and it is impossible to locate from the ground after the attachments on the ground change. Regarding the location problem of underground cable tunnels, a coordinated positioning system for the interior of the cable tunnel and the location on the ground is disclosed, including:

[0034] Positioning tags, worn on the body of the personnel in the tunnel, are used to locate the personnel in the tunnel;

[0035] Multiple sets of positioning base stations are installed in the tunnel to communicate with the positioning tags to obtain the positioning tag information and the distance information between the positioning tags and the positioning base stations;

[0036] The positioning server receives the positioning la...

Embodiment 2

[0058] In this embodiment, a working method of a cable tunnel internal and ground location co-location system disclosed in Embodiment 1 is disclosed, including:

[0059] The positioning base station and the positioning tag communicate with each other, obtain the positioning tag information inside the cable tunnel, and the distance information between the positioning base station and the positioning tag;

[0060] According to the distance information between the positioning base station and the positioning tag, the position information of the person in the cable tunnel is obtained, and according to the direction diagram of the cable tunnel, the deviation angle between the position of the person and the true north direction of the positioning base station is obtained, and according to the distance information Calculate the latitude and longitude offset between the personnel and the positioning base station, and obtain the latitude and longitude coordinates of the personnel in the...

Abstract

The invention discloses a cable tunnel interior and ground position cooperative positioning system and method, and the system comprises: a positioning label which is used for positioning a person in atunnel; multiple groups of positioning base stations, which are arranged in the tunnel to acquire distance information between the positioning label and the positioning base stations; a positioning server, which is used for receiving the distance information between the positioning label and the positioning base stations and calculating the position information of the personnel in the tunnel; anda ground client, which is used for receiving the position information sent by the positioning server and the distance information between the positioning label and the positioning base stations, andcalculating the longitude and latitude coordinates of the personnel according to a cable tunnel trend chart and the longitude and latitude coordinates of the positioning base stations. Position positioning of personnel in the cable tunnel can be completed on the ground, longitude and latitude coordinates of the personnel in the tunnel are obtained, the longitude and latitude positions of the personnel in the tunnel are obtained through the longitude and latitude coordinates, and when the personnel in the tunnel is positioned, positioning does not depend on ground appendages.

Description

technical field [0001] The present disclosure relates to a system and method for coordinating location inside and above ground of a cable tunnel. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the continuous development of urban construction activities, the ground appendages corresponding to the cable tunnel are constantly changing, the original ground reference objects have changed or disappeared, and the changes of the ground appendages have not been updated to the GIS map in time, making it difficult Existing buildings determine the specific location of the underground cable tunnel. [0004] In addition, the cable tunnel is located deep underground. There is no GPS signal or communication signal in the tunnel. Once the inspectors enter the tunnel, they cannot communicate with the personnel on the ground. [0005] If there is an...
