Abstract

The invention discloses an underground positioning and navigation method and system based on an electric power tunnel environment. The method includes establishing an electric power tunnel model according to the basic conditions of the electric power tunnel and the installation positions of monitoring equipment in the electric power tunnel; Perform information interaction, upload information to the server through the monitoring device; the server performs personnel positioning and / or navigation according to the installation position of the monitoring device in the power tunnel model. When an emergency occurs in the tunnel, the staff can operate on the mobile terminal. The system plans a reasonable evacuation route according to the location of the staff based on the previously established geographic model of the tunnel, and conducts underground navigation to assist the staff in safety. Evacuate from the dangerous area to ensure the personal safety of underground tunnel workers.

Description

technical field

[0001] The invention belongs to the technical field of electric power tunnels, and in particular relates to an underground positioning and navigation method and system based on electric power tunnel environments. Background technique

[0002] Underground navigation is a system for location, personnel positioning and route planning based on the communication and interaction between intelligent mobile terminals and monitoring equipment installed in the tunnel environment based on the tunnel environment. At present, most of the solutions to the trunk lines in the power system are affected by the limited space in the area and the safety and stability problems are to use power tunnels (cable trenches) to bury the transmission cables in underground tunnels. When there is a fault or abnormality in the cable line, the original solution is to send personnel directly into the tunnel to locate the fault and then repair the fault, which brings an important disadvantage: ...
