Problems solved by technology

[0002] In the existing technology, transmission line inspection systems such as UAV inspection systems have high operating load and high inspection costs, while inspection robot systems have a high degree of automation, but they are only suitable for inspections in small areas
[0003] On the other hand, the transmission line inspection system uses GPS for positioning. Although GPS positioning information is provided by navigation satellites, it has many advantages such as high positioning speed, high confidentiality, easy operation and all-weather operation, and positioning error has nothing to do with the voyage. Interference, especially a large number of high-voltage equipment in the substation will interfere with the work of GPS and affect the stability of positioning
The receiver of GPS positioning equipment is easy to lose lock and lose signal, resulting in the complete loss of navigation and positioning capabilities of the system

Embodiment Construction

[0013] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0014] like figure 1 and 2 As shown, an autonomously positioned transmission line inspection system includes an inspection vehicle (not shown in the figure) as the system carrier, and all components of the inspection system are set on the inspection vehicle.

[0015] The inspection system also includes a lidar, a GPS locator and a camera arranged on the top of the inspection vehicle. The memory is connected, and the inspection vehicle is also provided with a power supply. Among them, the GPS locator provides information such as the position, attitude, and speed of the inspection vehicle, and the laser radar provides accurate relative positional ...

Abstract

The invention discloses a self-localization type power transmission line inspection system, which comprises an inspection vehicle as the carrier of the system. The system is characterized by also comprising a laser radar, a GPS locator and a camera, wherein the laser radar, the GPS locator and the camera are arranged at the top of the inspection vehicle and are respectively connected with a single-chip microcomputer. The single-chip microcomputer is also connected with a display, a temperature sensor, a humidity sensor and a memory respectively. The inspection vehicle is also provided with a power supply. Preferably, the power supply comprises a solar cell and a storage battery. The solar cell is arranged at the top of the inspection vehicle. The self-localization type system is applied to a vehicle power transmission line inspection system and can autonomously take photos for identified targets. Meanwhile, the system is simple in structure and low in inspection cost.

Description

technical field [0001] The invention relates to a transmission line inspection system capable of autonomous positioning. Background technique [0002] In the prior art, the transmission line inspection system, such as the UAV inspection system, has high operating load and high inspection cost, while the inspection robot system has a high degree of automation, but it is only suitable for small area inspections. [0003] On the other hand, the transmission line inspection system uses GPS for positioning. Although GPS positioning information is provided by navigation satellites, it has many advantages such as high positioning speed, high confidentiality, easy operation and all-weather operation, and positioning error has nothing to do with the voyage. Interference, especially a large number of high-voltage equipment in the substation will interfere with the work of GPS and affect the stability of positioning. The receiver of GPS positioning equipment is easy to lose lock and l...
