Description

Unmanned helicopter system with relay system suitable for mountainous power grid inspection

technical field

The utility model relates to a medium-sized dedicated unmanned helicopter system suitable for mountainous power grid patrol inspection, especially an unmanned helicopter system with a relay system suitable for mountainous power grid patrol inspection.

Background technique

With the development of the power system, the transmission line is getting longer and longer, and the voltage level is getting higher and higher. At present, there are nearly 900,000 kilometers of power lines of 110kV and above in my country. Line inspection operations are carried out many times a year, and the workload is huge.

At present, the inspection methods adopted in my country are mainly manual inspection and manned helicopter inspection. Manual inspection is the inspection of power line inspection personnel walking along the line. The inspection method is mainly to check the lines and towers through binoculars. The manned helicopter inspection is that the power inspection personnel conduct inspections along the line above the line through the helicopter platform.

Take Fujian as an example. Fujian is located on the southeast coast of my country, and it is also a mountainous and hilly landform. Most of the transmission lines are over mountains and ridges. Many transmission lines are distributed in lakes and uninhabited areas. The traditional way of manual inspection and inspection of transmission lines is relied on. It consumes a lot of manpower, material and financial resources, but its effect and efficiency are difficult to improve. The work is heavy, inefficient, long-term, and highly dangerous. It brings many hidden dangers to the safety management of the power grid and is extremely unfavorable for ensuring the safe operation of the power grid.

In order to solve various problems in the inspection of transmission lines in mountainous areas, research institutions at home and abroad began to study how to improve the efficiency of inspections of power grid lines by means of technology since the late 1980s, mainly using manned helicopters for inspections of transmission lines. Manned helicopter inspection transmission line technology is widely used in the operation and management of UHV AC transmission lines and 110kV ~ 500kV transmission lines of North China Power Grid Corporation in my country. Utilize manned helicopter inspection technology and method to exist such as helicopter and its maintenance cost are expensive and personnel safety etc. problem. Due to the complex and changeable meteorological conditions in mountainous areas, it is extremely dangerous to fly at ultra-low altitude near power transmission lines. A slight error in the flight of a manned aircraft may cause serious consequences of aircraft crash and death, and it is also likely to bring disaster to the power network. sexual consequences. In the prior art, the unmanned helicopter system is used for inspection, but due to the limitation of the wind resistance capability of the UAV platform itself and the defects in the overall design of the system, the current unmanned helicopter can only fly within the visible range. If it exceeds the line of sight, the system will not be able to receive the flight data of the UAV and send flight control instructions. At this time, the UAV is completely out of control, and there is a danger of crashing at any time.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide an unmanned helicopter system for power grid inspection with a relay system, which is applicable to complex terrains and meteorological environments in mountainous areas.

An unmanned helicopter system with a relay system suitable for mountainous power grid inspection, including a ground station and an unmanned aerial vehicle platform, the ground station includes a vehicle-mounted radio station, and the unmanned aerial vehicle platform includes an on-board radio station, and is characterized in that: The unmanned helicopter system also includes a communication relay station, and the communication relay station includes two relay modes: a ground relay station and an air relay station, a vehicle radio station and a ground relay station, a ground relay station and an airborne station, or a vehicle station station and an air station , The wireless communication connection is adopted between the air relay station and the airborne radio station.

By adding a communication relay station in the entire unmanned helicopter system, the UAV (mission aircraft) + ground relay mode is suitable for situations where the mission aircraft cannot directly communicate with the ground station measurement and control vehicle, that is, the distance between the mission aircraft and the ground measurement and control vehicle Beyond the measurement and control range, or there are obstacles between the mission aircraft and the ground measurement and control vehicle. The images and telemetry signals collected by the mission machine are first sent to the ground relay station through a wireless link, and then the relay terminal is forwarded to the ground measurement and control vehicle terminal. On the contrary, the control commands of the ground measurement and control vehicle are also forwarded to the mission machine terminal through the ground relay station to control the task. machine working status. UAV (mission aircraft) + air relay (small unmanned helicopter) mode Aiming at the shortage of ground relay, a relay unmanned helicopter is added to the data link. The images and telemetry signals collected by the mission aircraft are first sent to the relay aircraft through the wireless link, and then forwarded to the ground measurement and control vehicle terminal through the relay aircraft. The working status of the task machine.

The ground relay mode is to set up wireless terminals on transmission towers.

The space relay mode is accomplished by setting up a relay terminal.

The above-mentioned ground relay mode is also equipped with an optical fiber communication terminal, which ensures that the UAV system can reliably measure and control in a range of more than 50km in mountainous areas.

In summary, the utility model has the following advantages compared with the prior art:

The utility model adds a selectable communication relay mode between the ground station of the unmanned helicopter system for power grid inspection and the UAV platform, so that it can ensure that the task machine can run under the monitoring state at any time, ensuring that the unmanned Human-machine safety.
