Detection robot and method of underground pipe network under weak GPS signal environment

Abstract

The invention discloses a detection robot and method of an underground pipe network under a weak GPS signal environment. The detection robot and method are suitable for detection and mapping of the underground pipe network, and the problems of the large detection amount and difficulty of the urban underground rain sewage pipe network are solved. The detection robot comprises a signal repeater, a remote controller and a self-rotating spherical robot; the remote controller is connected with the signal repeater through a wireless signal, the signal repeater is connected with the self-rotating spherical robot through a wireless signal, and the signal repeater is connected with a navigation satellite through a wireless signal; and the remote controller is hand-held by an operator to be operated, the self-rotating spherical robot is placed in the to-be-inspected underground pipe network, and the signal repeater is arranged in an initial launching well for launching the self-rotating spherical robot. The pipe distributing condition of the underground pipe network and the blockage condition in the pipe network can be detected, and thus the worker greatly conveniently maintains the underground pipe network.

Description

technical field [0001] An underground pipe network detection robot and detection method in a weak GPS signal environment are applicable to the technical fields of hydraulics and surveying and mapping equipment, and are especially suitable for the detection of underground rain and sewage pipe networks. Background technique [0002] The urban underground pipe network is intricate, with low visibility and high detection volume and difficulty. For urban water affairs and water environmental pollution management, it is very important to grasp the distribution, specific direction and connection status of the rainwater and sewage pipe network. Due to the dark and complex underground environment, it is obviously unrealistic to enter the pipe network for manual inspection. In order to effectively protect the safety of the staff, it is necessary to develop a robot that can detect in the underground pipe network. Due to the large length of the pipe network, which can be as long as sev...
