[0002] The navigation lighting system is a key safety device in the aviation field. Its core function is to provide comprehensive and accurate navigation services for aircraft. First, it clearly indicates the flight route and altitude to the pilot through a series of carefully designed lighting layouts, such as runway edge lights and approach lights, to ensure the precise operation of the aircraft during takeoff, landing and taxiing. Secondly, the system effectively reminds pilots to pay attention to ground obstacles, such as buildings and bridges, by setting warning lights such as anti-collision lights, so as to avoid potential risks. Overall, the navigation lighting system not only improves the safety of flight, but also ensures the smoothness of flight, especially in low visibility or bad weather conditions, its role is more prominent. Therefore, for the setting and maintenance of the navigation lighting system, it is necessary to strictly comply with relevant standards to ensure that it is always in the best working condition to escort aviation safety.

[0003] At present, the navigation lights need to be disassembled during the maintenance stage, and the disassembled navigation lights are taken to the inspection room for inspection. The inspection room can be set to dark light conditions to facilitate the test of light intensity; after the inspection, the qualified navigation lights are reinstalled, and the unqualified ones are replaced or repaired. This operation not only takes a long time to repair, but also has cumbersome steps for the operators. Later, a detection device installed on the front of the vehicle appeared. The device can be used at night when the influence of external ambient light is weak; the mobile detection method avoids the disassembly and assembly of all navigation lights to the inspection room.

The laser scriber 9 provides a reference point through two intersecting laser lines, and the navigation light 18 needs to be on the reference point. Therefore, preferably, a camera probe 8 for checking the position of the navigation light 18 is provided on the inner and outer sides of the back of the second section of the car body 2. The head end of the first section of the car body 1 is connected to the front of the car; the front of the car body is provided with a driving system; the camera probe 8 is connected to the display screen of the driving system. The part where the camera probe 8 is connected to the driving system is consistent with the existing reversing image. A battery is installed inside the first section of the car body 1 to provide power for the electrical equipment.

[0029] like Figure 4 , 5 As shown in Figures 7 and 8, the lifting mechanism 10 includes: a first electric push rod 10.1, a second electric push rod 10.2, a connecting frame 10.3, a first slide rod 10.4, a first slide sleeve 10.5, and a second slide sleeve 10.6; the middle of the back of the sunshade 4 is connected to the telescopic end of the first electric push rod 10.1; the end of the first electric push rod 10.1 is fixed to the inner wall of the second section box 2; the first slide sleeve 10.5 is fixed to both sides of the back of the sunshade 4; the first slide rod 10.4 is fixed to the inner wall of the second section box 2 at the tail; the first slide sleeve 10.5 moves up and down along the first slide rod 10.4; The middle of the back of the light measuring plate 3 is connected to the telescopic end of the second electric push rod 10.2; the end of the second electric push rod 10.2 is fixed to the inner wall of the second section box 2; a connecting frame 10.3 is fixed to the top of the light measuring plate 3; a second sliding sleeve 10.6 is provided on the connecting frame 10.3; the second sliding sleeve 10.6 moves up and down along the first sliding rod 10.4. A gap is reserved in the connecting frame corresponding to the position of the first electric push rod 10.1 and the second electric push rod 10.2 to avoid interference with them; the first electric push rod 10.1 first drives the shading plate 4 to descend, and then the second electric push rod 10.2 drives the light measuring plate 3 to descend; when ascending, the second electric push rod 10.2 first drives the light measuring plate 3 to rise, and the first electric push rod 10.1 then drives the shading plate 4 to rise; to avoid interference with the connecting frame 10.3.

[0030] like Figure 2 , 3 As shown, the bottom of the first section body 1 is provided with running wheels 11; the bottom sides and the end of the second section body 2 are provided with auxiliary wheels 12, and the auxiliary wheels 12 are driven by a motor. A second slide bar 13 is laterally provided on the top of the second section body 2; a third slide sleeve 14 is provided at the position of the first section body 1 corresponding to the second slide bar 13; the second slide bar 13 moves along the third slide sleeve 14.

[0033] Here’s how it works: After the driver reaches the position of the navigation light 18, he makes sure that the navigation light 18 is behind the rear of the vehicle through observation; the camera probe 8 can help with observation. After reaching the designated position, the movable door 6 is directly opposite the position of the navigation light 18, and the two sections of the carriage move outward and extend, so that the navigation light 18 enters the interior of the carriage. The intersection of the laser markings and the navigation light 18 must be at the same point. If they are not at the same point, the vehicle body can be moved forward and backward to make fine adjustments. After confirming that the positioning is accurate, the lifting mechanism 10 controls the light metering plate 3 and the sunshade plate 4 to descend, and the ambient light sensor 7 on the light metering plate 3 transmits the collected data to the PC host on one side of the vehicle body. By observing the data, the operator removes the navigation light 18 whose light intensity does not meet the requirements.
