[0002] When current thermal imaging equipment is tested in a single temperature and low temperature difference scene for a long time, image adjustment abnormalities, temperature measurement offset and low bit rate will occur. Therefore, a dynamically changing temperature scene is needed to achieve dynamic temperature changes and the conversion between dynamic and static scenes.
[0003] The existing thermal imaging image testing devices mainly include the following solutions:
[0004] Existing solution 1: Use black fonts to place in the picture. The main drawbacks are: the picture is single and there is no dynamic scene;

[0034] The hollow area 2 is arranged between the three heating areas 3, so as to effectively prevent the heating areas 3 with different temperatures from conducting heat;
[0035] A main control board 7 is fixedly mounted on the surface of the metal back plate 1. The output end of the main control board 7 is connected to the control end wire of the motor assembly 4. The main control board 7 is used to control the movement of the motor assembly 4. The motor assembly 4 includes a motor bracket 41, a motor 42, and a coupling 43. The mounting plate of the motor bracket 41 is fixedly mounted on the surface of the metal back plate 1. The motor 42 is mounted inside the motor bracket 41. The output shaft of the motor 42 is drivingly connected to the coupling 43. The other end of the coupling 43 is drivingly connected to the metal blade 5. The motor assembly 4 is connected to the metal blade 5. The motor assembly 4 is used to provide power for the metal blade 5.
[0036] The main control board 7 includes an MCU chip, a heating drive module 1, a heating drive module 2, a heating drive module 3, a 485 chip, and a motor drive chip. The heating drive module 1, the heating drive module 2, and the heating drive module 3 are respectively connected to the first silicone heating sheet 31, the second silicone heating sheet 32, and the third silicone heating sheet 33, so that the MCU chip controls the heating of the first silicone heating sheet 31, the second silicone heating sheet 32, and the third silicone heating sheet 33. The input end of the main control board 7 is electrically connected to the output end of the key, and the input end of the main control board 7 is electrically connected to the output end of the temperature sensor 1, the temperature sensor 2, and the temperature sensor 3, respectively. The output end of the main control board 7 is electrically connected to the digital tube, and the output end of the main control board 7 is electrically connected to the control end of the motor assembly 4.

[0037] Specifically, the main control board 7 controls the first silicone heating sheet 31, the second silicone heating sheet 32, and the third silicone heating sheet 33 to heat the corresponding heating areas 3, so that the three heating areas 3 transmit the temperatures in the corresponding three heating areas 3 to the main control board 7 through the temperature sensor 1, the temperature sensor 2, and the temperature sensor 3, and controls the first silicone heating sheet 31, the second silicone heating sheet 32, and the third silicone heating sheet 33 to heat the corresponding heating areas 3 to different temperatures, so that the video screen has richer thermal scenes, and then the main control board 7 controls the motor 42 to start and drive the coupling 43 to rotate, and the coupling 43 rotates to drive the metal fan blades 5 to rotate, and the three heating areas 3 are zero-blocked, partially blocked, and fully blocked. The blocking of different temperature areas realizes a dynamic temperature change scene in the thermal imaging screen;
[0038] Through the above structural design, the effect of long-term dynamic temperature change scene is achieved;
[0039] Control method steps for dynamic scenes of thermal imaging temperature measurement:
[0040] Step 1: The main control board is connected to a thermal imaging camera via the RS485 interface;
[0041] Step 2: The temperature of the corresponding heating area 3 is collected by temperature sensor 1, temperature sensor 2, and temperature sensor 3, and transmitted to the MCU chip. The MCU chip controls the corresponding first silicone heating sheet 31, second silicone heating sheet 32, and third silicone heating sheet 33 to start through heating drive module 1, heating drive module 2, and heating drive module 3, respectively, to heat the respective heating areas 3, so that the three heating areas 3 are heated to different temperatures;

[0043] Step 4: The MCU chip obtains the motor speed level and the temperature information transmitted by the temperature sensor according to the corresponding value calculated by the key, and outputs it to the digital tube to display the motor speed level and the temperature in different areas;
[0044] Step five, the MCU chip transmits 4-phase high and low electrical signals to the motor driver chip to control the rotation of the motor. The rotation of the motor drives the metal blades to rotate, so that the metal blades sequentially cover the rear heating area. When the first heating area is covered, only the second and third heating areas are in the picture. When the first and second heating areas are covered, only the third heating area is in the picture. After all the heating areas are covered, there is no heating area in the picture. The first, second and third heating areas are exposed in turn during the rotation process. During the rotation process, due to the covering and exposure of different heating areas, the scene in the thermal imaging picture is in a constantly changing state. Since the heating plates on the heating areas are set at different temperatures, only high temperature or low temperature areas appear during the operation of the device, realizing a dynamic temperature change scene.
