Embodiment Construction

[0042] Specific embodiments of the present invention are described in detail below in conjunction with accompanying drawing:

[0043] Such as Figure 1 to Figure 7 As shown, the present invention includes a robot. The robot includes a cable fault detection device. The cable fault detection device includes a thermal fault infrared detection device, a partial discharge ultraviolet detection device, and an electric field distribution detection device. The above-mentioned devices all belong to existing detection devices. I won't repeat them here. The fault monitoring system also includes a cable marking pile and a host computer. A robot is arranged between every two cable marking posts, so that a robot can monitor the cable segment between the two cable marking posts.

[0044] The cable marking pile includes a column 1, a solar panel 2, a lithium battery 3, a single-chip microcomputer, a GPS positioning module, a wireless power supply device, a data transfer device and a radio f...

Abstract

An underground cable fault monitoring system provided by the invention comprises a robot, a cable indication pile and an upper computer. The cable indication pile comprises a column, solar panels, a lithium battery, a single chip microcomputer, a GPS orientation module, a wireless power device, a data relay device and a radio-frequency induction device. The GPS orientation module is in communication connection with the upper computer; the robot includes an electric energy wireless receiving device configured to receive the wireless power device, a second wireless data receiving and dispatching module configured to match the first wireless data receiving and dispatching module of the data relay device, and a radio frequency card configured to cooperate with the radio-frequency induction device; and the upper computer includes a map configured to display the position of the cable. According to the invention, a cable indication pile is fully developed and is integrated with functions of power supply, data forwarding, geographic position orientation, a warning light and the like so as to supply uninterrupted electric energy for the robot and accurately orientate cable fault positions.

Description

technical field [0001] The invention relates to a cable fault monitoring method using an underground cable fault monitoring system. Background technique [0002] In order to facilitate laying and not affect the space above the ground, underground cables have gradually replaced overhead lines as the main laying method of power transmission lines. Ground wires and cables are generally laid in cable tunnels or cable ducts, and some areas have accumulated water and small animals like mice, which can easily cause the cables to be corroded, gnawed, and poorly ventilated to reduce the insulation performance of the cables. , In addition, the long-term overload of the cable line will also cause the reduction of the insulation performance of the cable. When the insulation performance of the cable is reduced to a certain extent, it is easy to fail. [0003] At present, most underground cable faults are detected by manual hand-held detection equipment, and robots are rarely used for de...
