Tethered drones have the ability to hover for a long time and can be deployed quickly, so they are widely used in various industries.

[0003] At present, due to the wide application of drones, drones are used for detection in situations where humans cannot reach or are inconvenient to handle, so as to detect areas that need to be detected.

The existing lighting system will power the lighting system through the tethered base station, and the lighting angle and lighting brightness of the lighting system will be controlled by the control mechanism. However, in actual applications, this method has the problem that the illuminated light spot is elliptical or nearly circular, and the light spot is usually brighter in the middle area than in the periphery, and the light spot cannot be completely bright.

The adjusting mechanisms 2 are respectively arranged at the ends of the two lamp boards 32 which are away from each other. The two adjusting mechanisms 2 respectively control the tilting of the lamp boards 32 along the axis of the connecting shaft 33, so that when the lamp boards 32 are adjusted, the lamp boards 32 on both sides of the connecting shaft 33 are adjusted independently of each other, thereby achieving the ability to adjust different inclination angles.

[0038] It also includes a flight control system, which includes a processor, a light spot control module, a height control module and an angle control module. The light spot control module is configured with preset lighting information. The light spot control module is used to control the lighting of the lighting lamp 4 that provides illumination according to the lighting information. The lighting information represents the illumination angle of the lighting lamp 4. The height adjustment module is configured with preset height information. The height adjustment module is used to control and adjust the flight height of the tethered platform according to the height information.

The flight control system also includes a spot compensation module and a spot recognition module. The spot recognition module is used to obtain the actual spot area formed and generate the actual area.

[0040] s=π[(tanx° / 2)*h] 2

[0041] Among them: s represents the effective area, x represents the lighting information, and h represents the height information, so that the size of the effective area can be calculated according to different heights and lighting information;

[0049] s=π{[tan(x°+y°) / 2]*h}[(tanx° / 2)*h]*a*z

[0050] Where: a represents the number of lights on, so as to calculate the effective area.

[0051] Compensation strategies include:

[0052] If the actual area is larger than the effective area, it is determined that one or more of the actual lighting data, the actual height data and the actual offset data exceeds the input lighting information, height information and offset information of the area algorithm when calculating the effective area. At this time, the compensation data includes the difference between the actual lighting data, the actual height data and the actual offset data and the lighting information, the height information and the offset information. The lamp group device 1 is compensated and adjusted according to the compensation data.

[0053] If the actual area is smaller than the effective area, it is judged that one or more of the actual lighting data, actual height data and actual offset data are smaller than the lighting information, height information and offset information input by the area algorithm when calculating the effective area. At this time, the compensation data includes the difference between the actual lighting data, actual height data and actual offset data and the lighting information, height information and offset information. The lamp group device 1 compensates and adjusts according to the compensation data.

[0054] The flight control system also includes a compensation judgment module, in which a judgment strategy is configured. The judgment strategy is specifically:

[0055] When the effective area is different from the actual area, the cause of the error is determined and failure data and / or physical damage data are generated, wherein the failure data indicates that the lighting lamp 4 has experienced use failure, and the physical damage indicates that the lamp assembly device 1 has experienced physical damage;

[0056] The flight control system generates maintenance data based on the exhaustion data and / or the physical damage data, and the maintenance data represents the area where the fault occurs and needs to be repaired.

[0057] As the lighting lamp 4 is used, it will generate heat and cause thermal damage to the lighting lamp 4. When the lighting lamp 4 is thermally damaged, the lighting brightness will decrease with the increase of the degree of thermal damage under the same input power. In response to this, the thermal damage will cause the lighting lamp 4 to fail, so that the effective area is different from the actual area. At this time, the flight control system will compensate. There are two compensation methods. One is to increase the input power of the failed lighting lamp 4 so that the lighting reaches the preset lighting level of the lighting information. The second is to turn off the failed lighting lamp 4 and control other lighting lamps 4 to compensate for the light to reach the effective area. When physical damage occurs, the effective area will also be different from the actual area. At this time, the lighting lamp 4 needs to be adjusted or repaired. The maintenance data is used to provide maintenance personnel with accurate positioning of the faulty area, so as to facilitate maintenance personnel to repair the faulty part to ensure that a light spot of an effective area can be formed.

[0058] Working principle and effect:

[0059] The spot matching strategy configured in the processor of the flight control system can calculate the effective area under the corresponding lighting information, height information and offset information, and compare the actual area with the effective area according to the spot recognition module and the spot compensation module. The light group device 1 is adjusted by the compensation data generated by the compensation strategy to match the actual area with the effective area, thereby forming sufficient lighting, providing a completely bright illumination spot, and improving the lighting efficiency.
