Abstract

The invention discloses a system and a method for positioning an inspection robot in a cable tunnel on the basis of a wireless network, and belongs to the technical field of wireless positioning. The integral system comprises a following network node, the inspection robot, the wireless sensor network and wireless sensor network base stations. The method for positioning the inspection robot in the cable tunnel includes that a distance-dependent attenuation model of the intensity of wireless electric signals is created; and a propagation environment of the wireless electric signals in the tunnel is divided into four types of conditions, the wireless sensor network base stations are respectively laid according to the four types of conditions of the tunnel, a plurality of wireless sensor network positioning modules are arranged in the base stations, a maintainer acquires a positioning request signal of the inspection robot when the inspection robot passes through a certain position in the cable tunnel, the positioning request signal is finally transmitted to the wireless sensor network base station arranged at a tunnel portal, and positioning information is displayed on a monitoring computer via a data interface. The system and the method bring convenience for the maintainer to position the inspection robot, and cables can be timely maintained.

Description

technical field [0001] The invention belongs to the technical field of wireless positioning, in particular to a wireless network-based positioning system and method for an inspection robot in a cable tunnel. Background technique [0002] In recent years, with the increase in the laying length of power cable tunnels in my country, the inspection work on the working conditions of the cables in the tunnels has become more and more arduous. threaten. Tunnel inspection robots can replace manual inspections of tunnels. Its main function is to transmit the working status picture of the cable in the tunnel, the temperature and humidity in the tunnel, the surface temperature of the power cable and other parameters in real time to the technicians outside the tunnel through the wireless network. When these status parameters are abnormal, the tunnel Foreign technicians can determine that there is a potential safety hazard in the power cable where the inspection robot is located, so tha...
