Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0022] This embodiment provides a rotating target simulator, specifically as follows: Figure 1 , Figure 2 , Figure 6 As shown, it includes: The transmitting unit 20 is used to transmit infrared images and includes a transmitting tube. The transmitting tube is equipped with a switch 202, a power supply 205, a light source 206, and an aperture 210. The light source 206 is electrically connected to the power supply 205 through the switch 202. The aperture 210 is provided with a specific pattern hole. The infrared light emitted by the light source 206 passes through the pattern hole on the aperture 210 and exits the transmitting tube. The control unit 10 is used to control the rotation parameters of the transmitter 20, and includes a control box 101, a drive mechanism, and a connecting structure; the drive mechanism is mounted on the control box 101, and the connecting structure is used to detachably mount the transmitter 20 on the output end of the drive mechanism.

[0023] When in use, connect the control unit 10 to the computer, input the specific operating data required into the computer, then set up the capture device (camera) at one end of the transmitter tube, and then press the switch 202. At this time, the light source 206 starts to emit infrared light. The light passes through the aperture 210 and is emitted. At the same time, the drive mechanism is started, causing the transmitter 20 to start rotating, and then infrared image capture begins.

[0024] Specifically, the rotation speed of the drive mechanism can be adjusted so that the rotation speed of the launching part 20 is maintained at 0-20° / s, and the infrared light emitted by the light source 206 has a wavelength of 633nm, 532nm, or 1064nm; the patterned hole on the aperture 210 can be a round hole, or it can be a missile, an airplane, etc., which can be replaced according to specific needs.

[0025] The above settings achieve the following beneficial effects: 1. The control unit and the launch unit can be detached, making transportation easier after disassembly; it also makes it more convenient to replace and maintain the launch unit. 2. Simulating dynamic targets: In infrared imaging systems, simulating the behavior of dynamic targets can simulate moving target objects, which is crucial for the testing and verification of infrared sensors, especially for evaluating the tracking capabilities of target-finding or monitoring systems. 3. Enhanced Detection Accuracy: By rotating the target, the sensor can capture the target from different angles, thus testing the system's detection accuracy and response capability under multi-angle and multi-directional conditions. This helps verify whether the infrared imaging system can handle complex scenarios; 4. Simulating target motion in real-world environments: Many infrared or thermal imaging devices need to handle complex moving targets in practical applications, such as flying objects, pedestrians, and vehicles. By simulating rotating targets, a testing platform that closely approximates real-world motion can be provided, making sensor performance evaluation more relevant to real-world applications.

[0026] In summary, this device can enhance the detection, tracking, and response capabilities of infrared imaging equipment, and facilitate the simulation and testing of complex dynamic scenes, thereby improving the performance and reliability of the equipment. Example 2:

[0027] This embodiment further extends the above embodiment, specifically as follows: Figures 3-6As shown, the launching tube includes a split tube 201 and an end plate 204. The end plate 204 is installed at the end of the split tube 201 and has a through hole in its center. A sealing ring 207 is installed on the end plate 204, and a lens 211 and a sealing tube 212 are installed on the sealing ring 207. The sealing tube 212 is used to compress and limit the aperture 210 to prevent it from loosening. At the same time, the sealing tube 212 is used to install the lens 211 on the sealing ring 207, which can prevent foreign objects from entering and effectively protect the aperture 210. The lens 211 can be a plane mirror or a convex mirror.

[0028] Furthermore, a condenser cup 208 is installed on the end plate 204. The condenser cup 208 is located between the aperture 210 and the light source 206. The condenser cup 208 is used to concentrate the light emitted by the light source 206 and prevent the light from scattering.

[0029] Furthermore, a filter 209 is also installed on the end plate 204. The filter 209 is located between the aperture 210 and the condenser cup 208. The filter 209 filters the light to ensure that the emitted light is what is needed for the experiment.

[0030] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again. Example 3:

[0031] This embodiment further extends the above embodiment, specifically as follows: Figures 1-4 As shown, the connection structure includes a connecting plate 103, a connecting pin 107, and a nut 108. A plurality of connecting pins 107 are rotatably connected to the connecting plate 103, and the nuts 108 are threadedly connected to the connecting pins 107. The launching tube also includes a docking plate 213, which is mounted on the split tube 201. The docking plate 213 is provided with a groove 203 that mates with the nut 108.

[0032] During installation, first align the docking plate 213 and the connecting plate 103 coaxially. Then, move the connecting pin 107 so that it engages in the slot 203. Next, rotate the nut 108 so that it presses against the docking plate 213, thereby locking the connection and attaching the transmitter 20 to the connecting structure. To remove it, simply reverse the above steps.

[0033] Furthermore, the drive mechanism includes a motor 102 and a reducer 104. The motor 102 and the reducer 104 are mounted on the control box 101. The reducer 104 is connected to the output end of the motor 102, and the connecting plate 103 is connected to the output end of the reducer 104.

[0034] The motor 102 drives the reducer 104, which in turn drives the connecting disk 103 to rotate, thereby realizing the rotation of the launching part 20.

[0035] Furthermore, a sensing lever 106 is provided on the connecting disk 103, and a sensor 105 is provided on the reducer 104. The sensor 105 is used to detect the sensing lever 106. When the connecting disk 103 rotates, the sensing lever 106 rotates synchronously. When the sensing lever 106 rotates to the sensor 105, the signal emitted by the transmitter of the sensor 105 will be blocked by the sensing lever 106, causing the sensor 105 to not receive the signal. The blocking interval time is used to determine the rotation speed of the connecting disk 103, and then the speed is adjusted accordingly.

[0036] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
