Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioning motion target response function detection device. Background Technology

[0002] Intelligent air conditioners can use millimeter-wave radar to identify and locate moving objects within a fan-shaped area directly in front of the radar. Combined with a wind deflector motor, this enables motion target response, including wind following and avoiding human movement. In typical production, related tests involve two methods: first, incoming material inspection of the radar components to ensure their quality; and second, powering on the entire unit to test the radar module's functionality. However, neither of these methods directly tests the air conditioner's motion target response function. A simple and direct test requires not only a worker as the moving target but also a relatively large testing space to prevent interference. This process demands high levels of physical strength and skill from the workers, wastes production line space, and cannot effectively guarantee testing time and procedures. Furthermore, the test results and conclusions are subject to debate, failing to meet lean manufacturing requirements.

[0003] Therefore, there is a need for an air conditioning motion target response function testing device that identifies targets in a radio frequency angle anti-simulation radar, uses a wind speed sensor as the basis for function realization judgment, a rotating platform as motion simulation, an absorbing anechoic chamber to prevent interference during the test, and is controlled by a standardized test process system to perform standardized quantitative testing of the air conditioning motion target response function. Utility Model Content

The rotating platform is arranged facing the radio frequency reflector. An air conditioner under test is placed on the rotating platform. A radar module is installed on the air conditioner under test. The radio frequency reflector is used to reflect the electromagnetic waves emitted by the radar module to test whether the radar module is qualified.

[0006] In a preferred embodiment of this invention, the radio frequency angle reflector includes three metal plates, with a first included angle formed between two adjacent metal plates, and the three metal plates are used to reflect the electromagnetic waves emitted by the radar module.

[0007] In a preferred embodiment of this invention, a wind speed sensor is disposed near the radio frequency angle, with the wind speed sensor facing the rotating platform, and the wind speed sensor is used to test the wind speed blown out by the air conditioner under test.

[0009] In a preferred embodiment of this invention, the testing device further includes a locking mechanism, which is inserted into the radio frequency angle reflector and abuts against the upright post to lock the radio frequency angle reflector onto the upright post.

[0010] In a preferred embodiment of this invention, a transmission gearbox is connected below the rotating platform, and the transmission gearbox drives the rotating platform to rotate, thereby driving the air conditioner under test to rotate.

[0011] In a preferred embodiment of this invention, the transmission gearbox is connected to a servo motor, which provides power to the transmission gearbox.

[0012] In a preferred embodiment of this invention, a sealed housing is also included, and both the testing device and the rotating platform are disposed within the sealed housing.

[0013] In a preferred embodiment of this invention, a wave-absorbing sponge layer is provided on the inner side wall of the sealed box, and the wave-absorbing sponge layer is used to absorb the electromagnetic waves emitted by the radar module.

[0014] In a preferred embodiment of this invention, a testing terminal is further included. The testing terminal is connected to the sealed enclosure and is used to control the testing device and the rotating platform inside the sealed enclosure, and to receive the test results of the air conditioner under test.

[0015] The beneficial effects of this utility model are as follows: This utility model provides an air conditioner moving target response function detection device, including a testing device and a rotating platform.

First, the air conditioner under test is placed on the rotating platform. The radar module of the air conditioner under test emits electromagnetic waves. When the electromagnetic waves come into contact with the RF angle reflector, the RF angle reflector reflects the electromagnetic waves back to the emission point of the radar module, thereby achieving the effect of using the RF angle reflector to simulate the radar module's target identification. At the same time, the rotating platform drives the air conditioner under test to rotate, thereby adjusting the relative position of the air conditioner under test to simulate a moving target for testing. The RF angle reflector and the rotating platform generate a simulated signal of relative motion within the radar module under test to replace human testing. This not only improves the automation level and efficiency of testing, but also reduces the time and labor costs of testing, meeting the needs of lean production. Attached Figure Description

[0036] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0037] Example 1

[0038] like Figures 1-5As shown, this embodiment provides an air conditioner motion target response function detection device, including a testing device 1 and a rotating platform 2. The testing device 1 includes a radio frequency reflector 3. The rotating platform 2 and the radio frequency reflector 3 are arranged facing each other. An air conditioner 4 to be tested is placed on the rotating platform 2. A radar module 5 is installed on the air conditioner 4 to be tested. The radio frequency reflector 3 is used to reflect the electromagnetic waves emitted by the radar module 5 in order to test whether the radar module 5 is qualified.

[0039] Radio frequency angle reflection 3 is made using the principle of radar target detection. The detection principle of millimeter wave radar is: to determine the distance by the time delay of electromagnetic waves in space reflection, and to determine the orientation of the object by the frequency shift of the reflected waveform.

[0040] The radar module 5 of the air conditioner under test 4 emits electromagnetic waves for scanning. When the electromagnetic waves pass through the radio frequency angle inversion 3, the incident electromagnetic waves are refracted within the radio frequency angle inversion 3 and finally reflected back to the emitting point of the radar module 5 in a direction parallel to but opposite to the original direction. This generates a strong echo signal on a macroscopic scale. By using the process of reflecting electromagnetic waves through the radio frequency angle inversion 3 to simulate the radar module 5 of the air conditioner under test 4 to identify the target, not only are time and labor costs saved, but the overall level of automation and testing efficiency are also improved.

[0041] The rotating platform 2 can rotate the air conditioner under test 4 by a certain angle to adjust the relative position of the radar module 5 and the radio frequency inverter 3. While keeping the position of the radio frequency inverter 3 constant, the rotating platform 2 rotates the radar module 5 of the air conditioner under test 4. During this movement, the relative position of the radar module 5 and the radio frequency inverter 3 changes, thus simulating the movement of the radio frequency inverter 3. The radio frequency inverter 3, in conjunction with the rotating platform 2, generates a simulated signal of relative motion within the radar module 5 under test to replace a human test, thereby simulating a moving target to test whether the radar module 5 is qualified.

[0042] This invention provides a device for detecting the moving target response function of an air conditioner, including a testing device 1 and a rotating platform 2. The testing device 1 includes a radio frequency (RF) angle reflector 3. The rotating platform 2 and the RF angle reflector 3 are arranged facing each other. An air conditioner under test (4) is placed on the rotating platform 2, and a radar module 5 is installed on the air conditioner under test (4). The RF angle reflector 3 is used to reflect the electromagnetic waves emitted by the radar module 5 to test whether the radar module 5 is qualified. First, the air conditioner under test (4) is placed on the rotating platform 2. The radar module 5 of the air conditioner under test (4) emits electromagnetic waves. When the electromagnetic waves come into contact with the RF angle reflector 3, the RF angle reflector 3 reflects the electromagnetic waves back to the emission point of the radar module 5, thereby achieving the effect of using the RF angle reflector 3 to simulate the radar module 5's target identification. At the same time, the rotating platform 2 drives the air conditioner under test (4) to rotate, thereby adjusting the relative position between the air conditioner under test (4) and the RF angle reflector 3 to simulate a moving target for testing. By combining the radio frequency angle reflector 3 with the rotating platform 2, a simulated signal of relative motion is generated within the radar module 5 of the test to replace the human tester. This not only improves the automation level and efficiency of the test, but also reduces the time and labor costs of the test, thus meeting the needs of lean production.

[0043] Example 2

[0044] like Figures 1-5 As shown, this embodiment provides an air conditioner motion target response function detection device, including a testing device 1 and a rotating platform 2. The testing device 1 includes a radio frequency reflector 3. The rotating platform 2 and the radio frequency reflector 3 are arranged facing each other. An air conditioner 4 to be tested is placed on the rotating platform 2. A radar module 5 is installed on the air conditioner 4 to be tested. The radio frequency reflector 3 is used to reflect the electromagnetic waves emitted by the radar module 5 in order to test whether the radar module 5 is qualified.

[0045] The radio frequency angle reflector 3 includes three metal plates 6, with a first included angle between two adjacent metal plates 6. The three metal plates 6 are used to reflect the electromagnetic waves emitted by the radar module 5.

[0046] Three metal plates 6 for reflecting electromagnetic waves and a base plate together form a radio frequency (RF) angle reflector 3. The RF angle reflector 3 is shaped like a triangular pyramid, with the three metal plates 6 serving as the three lateral faces of the pyramid. The angle between any two adjacent metal plates 6 is preferably 60 degrees. The three metal plates 6 are made of radar electromagnetic wave reflecting material, and the overall volume of the RF angle reflector 3 is preferably 40–50 cm³. 3 This makes the velocity attenuation of electromagnetic waves during the refraction process between the metal plates 6 not obvious, and the incident velocity and reflection velocity of electromagnetic waves on the three metal plates 6 are approximately the same.

[0047] like Figure 10 and Figure 11As shown, the three metal plates 6 are the X, Y, and Z faces of a triangular pyramid, respectively. The X, Y, and Z faces are all lateral faces of the pyramid. Let the velocity of a proton in the incident electromagnetic wave be V. In space, it can be decomposed into component velocities by projecting it onto the three perpendicular planes with an inverse radio frequency angle of 3. First, analyze two of the perpendicular planes. The initial velocity projected onto the X face is V0. When it collides with the Z face, it can be decomposed into two velocities V parallel to the Z and Y faces. z With V y After collision and reflection at the Z-plane, a velocity component V opposite to the vertical direction can be obtained. y1 The velocity V after colliding with the Y-plane 01 The direction of the velocity component perpendicular to the Y plane also changes to V. z1 This ultimately produces a velocity V1 parallel to V0 but in the opposite direction, with V1 having approximately the same velocity as V0. Similarly, under the influence of three mutually perpendicular planes, after reflection, the proton will eventually return to the radar module 5 of the air conditioner under test 4 at a velocity opposite to its original direction. Therefore, when the electromagnetic wave emitted by the radar module 5 of the air conditioner under test 4 passes through the radio frequency inflection angle 3, the electromagnetic wave is refracted at the three metal surfaces of the radio frequency inflection angle 3 and finally reflected back in a direction parallel to but opposite to the incident direction.

[0048] The presentation of the signal simulated by the radio frequency angle inversion 3 in the radar, and the process of finally obtaining the distance and angle, such as Figure 12 As shown, Figure 12 This is a schematic diagram of a millimeter-wave radar transmitting a linear frequency modulated wave.

[0049] Figure 12 The solid line in the diagram represents the transmitted signal, and the dashed line represents the signal received by the radar module 5 after the radio frequency angle reflection signal is reflected. The difference frequency f between the signals is obtained through a mixer and a low-pass filter. The time difference T can be calculated using formula (1). Then, the distance L between the radar module 5 and the radio frequency angle reflection signal is calculated using the radar principle formula (2), where k is the frequency modulation slope and V is the electromagnetic wave propagation speed.

[0050] T = f / k (1);

[0051] L=VT / 2=Vf / 2k (2);

[0052] Radar module 5 measures the relative angle of the radio frequency angle inverse 3 as follows: Figure 13 As shown, radar module 5 obtains the receiving distances L and L+δL through two receiving antennas A1 and A2, where the distance between the two receiving antennas is d. According to the angle estimation principle, a change in the distance from the object to the millimeter-wave radar will cause a change in the phase of the intermediate frequency signal corresponding to the object. The phase change of the intermediate frequency signal is given by formulas (3), (4), and (5), and the relative angle θ is calculated.

[0056]

[0057] The change in the angle of the moving target simulated by the radio frequency angle reflection 3 requires the assistance of the rotating platform 2. The rotating platform 2 can achieve fixed-point angle rotation. By rotating the direction facing the air conditioner under test 4, the relative movement of the radar module 5 target can be achieved without moving the test device 1. Figures 14-16 This diagram illustrates three different relative angles between radar module 5 and radio frequency angle reflector 3. The yellow area represents the fan-shaped detection range of radar module 5, and the small black circle represents radio frequency angle reflector 3. The radar wave detection area is set to 90° in front. The logic diagram of the test program is as follows. Figures 17-19 As shown in Table 1, the rotation process of the rotating platform 2 and the corresponding angle changes are as follows.

[0058] This embodiment provides an air conditioner moving target response function detection device. The radio frequency angle reflector 3 includes three metal plates 6, with a first included angle between adjacent metal plates 6. The three metal plates 6 are used to reflect the electromagnetic waves emitted by the radar module 5. When the electromagnetic waves emitted by the radar module 5 of the air conditioner under test 4 scan the radio frequency angle reflector 3, the electromagnetic waves are refracted between the three metal plates 6 of the radio frequency angle reflector 3, and finally reflected back to the emission point of the radar module 5 of the air conditioner under test 4 in a direction parallel to but opposite to the original direction. This generates a strong echo signal on a macroscopic scale, which acts as a strong echo target in the radar module 5. Therefore, the radio frequency angle reflector 3 can become a simulated target scanned by the radar module 5 of the air conditioner under test 4. A rotating platform 2 is set up. By rotating the direction facing the radar module 5 of the air conditioner under test 4 by a certain angle through the rotating platform 2, the simulated target scanned by the radar module 5 will move relatively without moving the radio frequency angle reflector 3, thereby realizing the simulation of moving target testing. The radar module 5 generates a simulated signal of relative motion to replace a human for testing. This not only enables automated and rapid testing but also saves a significant amount of time and labor costs. It solves the problem of requiring workers to perform fixed-point movements as moving targets when testing the motion target response function on the production line, thereby greatly improving testing and production efficiency.

[0059] Example 3

[0060] like Figures 1-5As shown, this embodiment provides an air conditioner motion target response function detection device, including a testing device 1 and a rotating platform 2. The testing device 1 includes a radio frequency reflector 3. The rotating platform 2 and the radio frequency reflector 3 are arranged facing each other. An air conditioner 4 to be tested is placed on the rotating platform 2. A radar module 5 is installed on the air conditioner 4 to be tested. The radio frequency reflector 3 is used to reflect the electromagnetic waves emitted by the radar module 5 in order to test whether the radar module 5 is qualified.

[0061] A wind speed sensor 7 is disposed near the radio frequency angle reflector 3, and the wind speed sensor 7 faces the rotating platform 2. The wind speed sensor 7 is used to test the wind speed blown out by the air conditioner 4 under test.

[0062] like Figures 6-7 As shown, the testing device 1 also includes a pole 8, the wind speed sensor 7 and the radio frequency angle reflector 3 are mounted on the pole 8, and the wind speed sensor 7 is located above the radio frequency angle reflector 3.

[0063] The testing device 1 also includes a locking mechanism 9, which is inserted into the radio frequency inverter 3 and abuts against the upright 8 to lock the radio frequency inverter 3 onto the upright 8.

[0064] A test bench 15 is also provided below the test device 1. The plane of the test bench 15 facing the rotating platform 2 is the first end face, and the plane of the test bench 15 facing the test device 1 is the second end face. The height of the first end face is higher than the second end face. The height of the RF angle reflector 3 is greater than the height of the first end face so as to reflect the electromagnetic waves emitted from the radar module 5. The part of the first end face that is higher than the second end face can block the area of ​​the pole 8 located below the RF angle reflector 3. A wave-absorbing sponge layer 13 is provided on the first end face. The wave-absorbing sponge layer 13 is used to absorb the electromagnetic waves emitted by the radar module 5 so as to reduce the interference of electromagnetic waves from other directions on the RF angle reflector 3.

[0065] Preferably, the upright 8 is cylindrical, and four support rods are connected near the bottom of the upright 8. The four support rods firmly fix the upright 8, allowing it to be stably placed on the second end face of the test bench 15. The locking mechanism 9 is inserted into the RF angle reflector 3 and abuts against the upright 8 to lock the RF angle reflector 3 onto the upright 8. Preferably, when the locking mechanism 9 is released, the RF angle reflector 3 can move up and down along the upright 8 to adjust its position on the upright 8 at any time. After adjusting the position of the RF angle reflector 3 on the upright 8, the locking mechanism 9 is tightened to fix the RF angle reflector 3 onto the upright 8.

[0066] An air speed sensor 7 is positioned above the radio frequency angle inversion 3. An impeller 16 is mounted on the side of the air speed sensor 7 facing the rotating platform 2. The air speed sensor 7 calculates the convective wind speed from the air conditioner under test 4 by measuring the rotational speed of the impeller 16. It can quantitatively measure whether the wind speed meets the set values ​​for two functions of the air conditioner at the relative angle between the air outlet of the air conditioner under test 4 and the air speed sensor 7. These two functions are "wind following the person" and "wind avoiding the person." The "wind following the person" function means that after the radar module 5 of the air conditioner under test 4 locates the human body, it automatically adjusts the guide vanes of the air outlet of the air conditioner under test 4 to ensure that the direction directly facing the air outlet of the air conditioner under test 4 is always the location of the human body. The "wind avoiding the person" function means that after the radar module 5 of the air conditioner under test 4 locates the human body, it automatically adjusts the guide vanes of the air outlet of the air conditioner under test 4 to ensure that the direction directly facing the air outlet of the air conditioner under test 4 avoids the location of the human body.

[0067] When testing the "Follow-the-Human" function of the air conditioner under test (4), the rotating platform 2 rotates the air outlet of the air conditioner under test (4) to a certain angle, and the radar module 5 of the air conditioner under test (4) emits electromagnetic waves. When the electromagnetic waves scan the radio frequency inverted angle 3, the radio frequency inverted angle 3 reflects the electromagnetic waves back to the emitting point of the radar module 5. The radio frequency inverted angle 3 serves as the simulated target scanned by the radar module 5 of the air conditioner under test (4). At this time, the wind speed measured by the wind speed sensor 7 is used to determine whether the "Follow-the-Human" function of the air conditioner under test (4) is higher than the set value. If the data collected by the wind speed sensor 7 is higher than the set value, it means that by adjusting the angle of the air outlet of the air conditioner under test (4) through the rotating platform 2, the air outlet can be automatically adjusted to the direction corresponding to the radio frequency inverted angle 3, i.e., the simulated human target. This test shows that the "Follow-the-Human" function of the air conditioner under test (4) is qualified. If the data collected by the wind speed sensor 7 is lower than the set value, it means that by adjusting the angle of the air outlet of the air conditioner under test (4) through the rotating platform 2, the air outlet cannot be automatically adjusted to the direction corresponding to the radio frequency inverted angle 3, i.e., the simulated human target. This test shows that the "Follow-the-Human" function of the air conditioner under test (4) is unqualified.

[0068] When testing the air conditioner under test (Air Conditioner 4) for its wind avoidance function, the rotating platform 2 rotates the air outlet of Air Conditioner 4 to a certain angle. Then, the radar module 5 of Air Conditioner 4 emits electromagnetic waves. When the electromagnetic waves scan the radio frequency inverted angle 3, the inverted angle 3 reflects the electromagnetic waves back to the emitting point of Radar Module 5. Radio frequency inverted angle 3 serves as the simulated target scanned by Radar Module 5 of Air Conditioner 4. The wind speed measured by the wind speed sensor 7 is then used to determine whether the wind avoidance function of Air Conditioner 4 is qualified. If the data collected by the wind speed sensor 7 is lower than the set value, it indicates that rotating the air outlet of Air Conditioner 4 by the rotating platform 2 automatically avoids the position of Radio Frequency Inverted Angle 3, thus testing that the wind avoidance function of Air Conditioner 4 is qualified. If the data collected by the wind speed sensor 7 is higher than the set value, it indicates that rotating the air outlet of Air Conditioner 4 by the rotating platform 2 does not automatically avoid the position of Radio Frequency Inverted Angle 3, thus testing that the wind following function of Air Conditioner 4 is unqualified.

[0070] type parameter type parameter Sensing wind speed 0-15m / s Operating temperature -20℃-60℃ Repeatability 0.1m / s Start-up fan speed 0.5m / s

[0071] In this embodiment, a wind speed sensor 7 is positioned near the RF angle reflector 3, facing the rotating platform 2. The wind speed sensor 7 is used to test the wind speed emitted by the air conditioner 4 under test. The testing device 1 also includes a support pole 8, on which the wind speed sensor 7 and the RF angle reflector 3 are mounted, with the wind speed sensor 7 positioned above the RF angle reflector 3. The testing device 1 also includes a locking mechanism 9, which is inserted into the RF angle reflector 3 and abuts against the support pole 8 to lock the RF angle reflector 3 onto the support pole 8. Loosening the locking mechanism 9 allows the RF angle reflector 3 to be moved up and down, thereby changing its position on the support pole 8, allowing the height of the RF angle reflector 3 to be flexibly adjusted according to actual needs. The wind speed is measured by the wind speed sensor 7 to determine whether the air conditioner 4 under test has the functions of "wind following the person" and "wind avoiding the person". When conducting the "Following Person Movement" function test, if the wind speed measured by the wind speed sensor 7 is higher than the wind speed setting value of the air conditioner under test 4, it indicates that the air outlet of the air conditioner under test 4 can automatically adjust to face the simulated target, thus determining that the "Following Person Movement" function of the air conditioner under test 4 is qualified. When conducting the "Avoiding Person Movement" function test, if the wind speed measured by the wind speed sensor 7 is lower than the wind speed setting value of the air conditioner under test 4, it indicates that the air outlet of the air conditioner under test 4 can automatically avoid the direction of the simulated target, thus determining that the "Avoiding Person Movement" function of the air conditioner under test 4 is qualified. The performance of the wind speed sensor is shown in Table 2.

[0072] This embodiment uses the radio frequency angle reflection 3 to simulate the radar module 5 to identify the target, i.e., the human body, and the wind speed sensor 7 as the basis for judging the function. Combined with the rotating platform 2 and the wind speed sensor 7, the functions of the air conditioner under test 4, which follow the movement of people and avoid the movement of people, are simulated and tested. This improves the automation level and testing efficiency of the radar module 5 for testing the air conditioner under test 4, reduces the required working hours and personnel, lowers the testing cost, and meets the needs of lean production.

[0073] Example 4

[0074] like Figures 1-5 As shown, this embodiment provides an air conditioner motion target response function detection device, including a testing device 1 and a rotating platform 2. The testing device 1 includes a radio frequency reflector 3. The rotating platform 2 and the radio frequency reflector 3 are arranged facing each other. An air conditioner 4 to be tested is placed on the rotating platform 2. A radar module 5 is installed on the air conditioner 4 to be tested. The radio frequency reflector 3 is used to reflect the electromagnetic waves emitted by the radar module 5 in order to test whether the radar module 5 is qualified.

[0075] A wind speed sensor 7 is disposed near the radio frequency angle reflector 3, and the wind speed sensor 7 faces the rotating platform 2. The wind speed sensor 7 is used to test the wind speed blown out by the air conditioner 4 under test.

[0076] like Figures 8-9 As shown, a transmission gearbox 10 is connected below the rotating platform 2. The transmission gearbox 10 drives the rotating platform 2 to rotate, thereby driving the air conditioner 4 under test to rotate.

[0077] The transmission gearbox 10 is connected to a servo motor 11, which provides power to the transmission gearbox 10.

[0078] The transmission gearbox 10 and the servo motor 11 are connected by a coupling 17. The servo motor 11 transmits power to the transmission gearbox 10 through the coupling 17. When the servo motor 11 rotates, it drives the coupling 17 to rotate, thereby driving the transmission gearbox 10 to rotate. When it is necessary to adjust the position of the air conditioner 4 under test, the servo motor 11 is started first. The servo motor 11 drives the transmission gearbox 10 to rotate through the coupling 17, thereby driving the rotating platform 2 and the air conditioner 4 under test to rotate, achieving the effect of adjusting the air conditioner 4 under test to a suitable angle through rotation.

[0079] A base is provided below the transmission gearbox 10 and the servo motor 11, and both the transmission gearbox 10 and the servo motor 11 are fixed on the base. When the servo motor 11 is started, since both the servo motor 11 and the transmission gearbox 10 are fixed on the base, the servo motor 11 will not be displaced during operation. This also prevents the transmission gearbox 10 from displacing while driving it to rotate, greatly improving the stability of the servo motor 11 and the transmission gearbox 10 during operation.

[0080] When testing the "Following Person" and "Avoiding Person" functions of the air conditioner under test (4), to simulate the movement of a moving target, the servo motor 11 is activated to drive the transmission gearbox 10 to rotate, thereby rotating the rotating platform 2 and the air conditioner under test (4) by a certain angle. This causes the direction of the air outlet of the air conditioner under test (4) to deviate from the direction of the testing device 1 by a certain angle. During the rotation of the air conditioner under test (4), the wind speed sensor 7 begins to collect the received wind speed data. If the wind speed collected by the wind speed sensor 7 is higher than the set value during the "Following Person" function test, it indicates that the air conditioner under test (4) can automatically adjust the direction of the air outlet so that the air outlet faces the position of the radio frequency angle inverse 3, thus determining that the "Following Person" function of the air conditioner under test (4) is qualified. If the wind speed collected by the wind speed sensor 7 is lower than the set value during the "Avoiding Person" function test, it indicates that the air conditioner under test (4) can automatically adjust the air outlet so that the air outlet avoids the position of the radio frequency angle inverse 3, thus determining that the "Avoiding Person" function of the air conditioner under test (4) is qualified.

[0081] In this embodiment, a wind speed sensor 7 is positioned near the RF angle reflector 3, facing the rotating platform 2. The wind speed sensor 7 is used to test the wind speed emanating from the air outlet of the air conditioner under test 4. A transmission gearbox 10 is connected below the rotating platform 2, which drives the rotating platform 2 to rotate, thereby driving the air conditioner under test 4 to rotate. A servo motor 11 is connected to the transmission gearbox 10, which provides power to the transmission gearbox 10. The servo motor 11 drives the transmission gearbox 10 to rotate, thereby driving the rotating platform 2 and the air conditioner under test 4 to rotate. When testing the air conditioner under test 4's "wind following" and "wind avoiding" functions, the air outlet of the air conditioner under test 4 can be rotated to simulate the movement of a moving target. The wind speed sensor 7 is then used to test the wind speed to determine whether the air conditioner under test 4's "wind following" and "wind avoiding" functions are qualified. This not only enables rapid testing, saving a lot of time, but also significantly reduces labor costs, solving the problem of testing the air conditioner's motion target response function on the production line, thereby improving testing efficiency and production efficiency.

[0082] Example 5

[0083] like Figures 1-5 As shown, this embodiment provides an air conditioner motion target response function detection device, including a testing device 1 and a rotating platform 2. The testing device 1 includes a radio frequency reflector 3. The rotating platform 2 and the radio frequency reflector 3 are arranged facing each other. An air conditioner 4 to be tested is placed on the rotating platform 2. A radar module 5 is installed on the air conditioner 4 to be tested. The radio frequency reflector 3 is used to reflect the electromagnetic waves emitted by the radar module 5 in order to test whether the radar module 5 is qualified.

[0084] The air conditioning motion target response function detection device also includes a sealed housing 12, and the test device 1 and the rotating platform 2 are both located inside the sealed housing 12.

[0085] An absorbing sponge layer 13 is provided on the inner side wall of the sealed housing 12. The absorbing sponge layer 13 is used to absorb the electromagnetic waves emitted by the radar module 5.

[0086] The air conditioner motion target response function detection device also includes a test terminal 14, which is connected to the sealed box 12. The test terminal 14 is used to control the test device 1 and the rotating platform 2 inside the sealed box 12, and to receive the test results of the air conditioner 4 under test.

[0087] The sealed enclosure 12 is a dark chamber, with an entirely sealed interior environment. The absorbing sponge layer 13 is made of absorbent and foamed polyurethane material, with an overall density of 1.3–5.5 kg / m³ and an operating temperature range of -50–80℃. The absorbing sponge layer 13 is adhered and arranged around the entire inner perimeter of the dark chamber. Utilizing the electromagnetic wave absorption function of polyurethane, a high-molecular-weight material, it absorbs electromagnetic wave energy without reflection, achieving radar wave reflection shielding inside the dark chamber. This not only eliminates clutter interference in the testing environment but also significantly improves testing accuracy. The signal shielding capability of the dark chamber also allows for compression of the testing space, saving testing space and time.

[0088] The test terminal 14 includes a power module, a computer terminal, and a motor drive box. The test terminal 14 connects to the rotating platform 2 and the test device 1 through pre-drilled holes in the dark box, enabling communication and control between the rotating platform 2 and the test device 1. The test terminal 14 also includes a control system, which consists of two parts: process flow control and control program. The process flow control includes visual alarms and test programs. The test logic system includes wind-following-person movement testing and wind-avoiding-person movement testing systems. According to the process flow diagram, after the employee installs the air conditioner 4 under test on the rotating platform 2 facing the test device 1, they leave the dark box and click on the test interface on the test terminal 14 to start the test program and wait for the test to complete. Various test tasks are completed by the rotating platform 2 and the test device 1 inside the dark box, including electromagnetic shielding, simulated radar targets, and simulated motion.

[0089] like Figure 17 As shown, when test terminal 14 starts the test task, the air conditioner under test 4 is first placed on the rotating platform 2. The computer terminal starts the test, and the program begins to check whether the dark box door is closed and whether there is anyone inside. If the dark box door is not closed and / or there is someone inside, a red alarm will sound, and the test equipment will stop working. If the dark box door is closed and there is no one inside, the timer will determine whether the test time has been reached. If the test time is within the time limit, the buzzer will not sound, and the test program can proceed normally. You can choose to perform the wind-following-person movement test or the wind-avoiding-person movement test. When the timer determines that the test time has been reached, the buzzer will sound, and the test equipment will stop working. At this time, you can choose whether to remove the material and reset the test program. If the material is removed and the test program is reset, the buzzer will stop sounding, and the next test can begin.

[0090] This embodiment provides an air conditioner motion target response function detection device, which also includes a sealed enclosure 12. The testing device 1 and the rotating platform 2 are both disposed within the sealed enclosure 12. An absorbing sponge layer 13 is provided on the inner side wall of the sealed enclosure 12, which absorbs electromagnetic waves emitted by the radar module 5. A testing terminal 14 is also included, connected to the sealed enclosure 12. The testing terminal 14 controls the testing device 1 and the rotating platform 2 inside the sealed enclosure 12 and receives the test results from the air conditioner 4 under test. By attaching the absorbing sponge layer 13 to the inner side wall of the sealed enclosure 12, the absorption function of the absorbing sponge layer 13 not only eliminates noise interference in the testing environment and significantly reduces the testing space, but also improves testing accuracy and saves testing time. The connection between the testing terminal 14 and the dark box enables the testing terminal 14 to control the rotating platform 2 and the testing device 1 inside the dark box. The test terminal 14 stores test programs, which can perform two functions of the air conditioner under test 4, namely, wind following human movement and wind avoiding human movement, in a dark box, and collect test data from the test device 1. The test terminal 14 adopts a standardized test process control system, which realizes quantitative testing of the air conditioner's motion target response function under a unified standard, improves the overall automation level and testing efficiency of the test, reduces the required working hours and labor costs, and meets the needs of lean production.
