Along with the development of urbanization construction, urban tunnels and pipelines are more and more, the inspection work in the tunnels or the pipelines is heavier, and the inspection robot replaces manpower to finish the inspection work and is more and more popular. The main function of the inspection robot is that the working state pictures of the cable in the tunnel or the pipeline, the temperature and the humidity in the tunnel or the pipeline, the surface temperature of the power cable and other infrastructure and other parameters are transmitted to the technicians outside the tunnel in real time through a wireless network, when the state parameters are abnormal, the technicians outside the tunnel or the pipeline can determine the potential safety hazard of the position where the inspection robot is located, and therefore the technicians can be organized to maintain the corresponding positions.
In order to ensure that a tunnel or pipeline robot can normally communicate with an outside technician in the whole tunnel or pipeline and transmit video images, voice, control instructions and environment monitoring data to the technician, the prior art mainly adopts two communication methods, namely 1, signal coverage is carried out on the tunnel or pipeline by using a leakage cable, a wireless signal is radiated to the outside through a cable slot, 2, a plurality of WiFi APs are deployed in the tunnel or pipeline, are connected with a directional antenna through a feeder line and are respectively connected with a switch through an optical fiber trunk line, and then the network connection is established between the switch and a management server arranged outside the tunnel or pipeline through the optical fiber trunk line.
However, the first method has a relatively large signal attenuation when the distance is relatively long, and the communication cost is relatively high because the cost of the leaky cable is expensive. The second method also needs to lay cable optical fibers in the tunnel or the pipeline in advance, so that the use cost is high, and the coverage of the WiFi signal is small. Therefore, the prior art has the defects of high manufacturing cost, unstable communication and the like.
