[0002] At present, under strong electromagnetic environment, electronic equipment may experience control board chip damage, program crash, display screen flashing, button false triggering, etc., which requires these components of electronic equipment to withstand certain radiation anti-interference capabilities. In the field of consumer home appliances, the sales volume of a single product is often in the millions to kilowatt levels. When the product is designed and tested, the probability of the above problems is small. When mass-produced, due to the differences in electronic equipment components, the probability of the above problems becomes higher.

The detection system 100 includes a test cavity 12, an antenna component 14, a radio frequency module 16, an environmental component 18 and a control component 20.

[0038] A test cavity 22 is provided in the test cavity 12, and the test cavity 22 is used to place the device to be tested. The antenna assembly 14 is installed in the test cavity 12. The RF module 16 is electrically connected to the antenna assembly 14, and the RF module 16 is used to output a RF signal, and the RF signal is fed to the test cavity 22 through the antenna assembly 14.

[0043] In one embodiment, the radio frequency signal includes but is not limited to a radio frequency signal in the microwave frequency band. The radio frequency module 16 may include a signal generating circuit, an incident power detection circuit, and a reflected power detection circuit. The signal generating circuit may include components such as a crystal oscillator, an amplifier, a circulator, and a phase shifter. The incident power detection circuit is used to detect the power of the radio frequency signal incident to the test cavity 22. The radio frequency module 16 can adjust (for example, using PID control adjustment) the radio frequency signal output by the signal generating circuit according to the data fed back by the incident power detection circuit, so that the power of the radio frequency signal incident to the test cavity 22 is close to or equal to the target power.

[0044] The reflected power detection circuit is used to detect the power of the RF signal reflected by the test cavity 22.

For example, the parameters of the RF signal include at least one of the frequency band, phase, and power of the RF signal, and the environmental parameters of the test cavity 22 include at least one of the target temperature and target humidity of the test cavity 22, so as to generate a variety of RF signals within the corresponding frequency band under a certain temperature and / or humidity, and to more completely simulate the complex electromagnetic interference scenario of the device under test in the actual environment.

The combination relationship may include a combination value of at least one of the frequency band, phase, and power of the RF signal and at least one of the target temperature and target humidity of the test chamber 22.

The combination value B includes the frequency band B1, phase B2, and power B3 of the RF signal, and the target temperature B4 and target humidity B of the test chamber 22, and so on.

[0048] The detection system 100 further includes a door body 30. An opening 32 is provided on one side of the test chamber 22. The door body 30 is rotatably mounted at the opening 32 to open or close the opening 32. When the door body 30 opens the opening 32, an operator can take and place the device to be tested. When the door body 30 is closed, testing can be performed. The door body 30 is used to prevent the radio frequency signal from leaking from the test chamber 22 to the outside air, thereby improving the safety of the detection process.

[0049] During the detection, the device under test can be powered on, and the RF module 16 generates a corresponding RF signal according to the set parameters of the RF signal. The RF signal is fed into the test cavity 22 through the antenna component 14 and radiated to the device under test. The environmental component 18 adjusts at least one of the humidity and temperature of the test cavity 22 according to at least one of the target temperature and target humidity of the test cavity 22. The detection system 100 can detect whether the device under test has abnormalities during the detection process, such as flashing screen, black screen and other abnormal phenomena, by means of a camera, and can also use the sound detection device 36 to detect whether the device under test has abnormal phenomena such as cracking of parts and sounds. If an abnormal phenomenon occurs, the test result is that the device under test is unqualified under the set parameters of the RF signal and the target temperature and target humidity of the test cavity 22. If no abnormal phenomenon occurs, the test result is that the device under test is qualified under the set parameters of the RF signal and the target temperature and target humidity of the test cavity 22.

[0051] In this way, the temperature of the test chamber 22 can be adjusted.

[0052] Specifically, the detection device 36 may include a temperature detection device. Figure 3 In the embodiment, the temperature detection device can be installed on the back plate of the test cavity 12. The test instruction can include the target temperature of the test cavity 22. The control component 20 controls the temperature adjustment device 34 to operate according to the difference between the current temperature of the test cavity 22 detected by the detection device 36 and the target temperature, so that the current temperature of the test cavity 22 is equal to or close to the target temperature of the test cavity 22. It can be understood that the detection device 36 is not limited to being installed on the back plate of the test cavity 12, and can also be installed at other positions of the test cavity 12, which is not specifically limited here.

[0053] exist Figure 3 In the embodiment, the temperature adjustment device 34 can be installed on the back plate of the test chamber 12. It can be understood that the temperature adjustment device 34 is not limited to being installed on the back plate of the test chamber 12, and can also be installed at other positions of the test chamber 12, which is not specifically limited here.

[0055] In this way, the temperature of the test chamber 22 can be adjusted by using hot air.

[0056] Specifically, in one embodiment, the heating element 38 may be an electric heating tube. The fan further includes a motor, which is located outside the test chamber 22 and connected to the blades 40 via an output shaft. When the current temperature of the test chamber 22 is lower than the target temperature, the heating element 38 is powered on to heat the air in the test chamber 22, and the motor drives the blades 40 to rotate, so that the heated air is blown to other positions of the test chamber 22, so that the temperature of the test chamber 22 quickly tends to be uniform, and then the temperature of the test chamber 22 is adjusted by hot air.

[0057] In some embodiments, the temperature regulating device 34 includes a refrigeration element (not shown), which is used to reduce the temperature of the test cavity 22. Specifically, the refrigeration element may include a semiconductor refrigeration sheet. The cold end of the refrigeration element may be located in the test cavity 22, and the hot end is located outside the test cavity 22. When the current temperature of the test cavity 22 is greater than the target temperature, the refrigeration element is powered on to cool the cold end. The temperature regulating device 34 may also include a fan, which blows cold air to other positions of the test cavity 22 when the fan is working, so that the temperature of the test cavity 22 quickly tends to be uniform, and then the temperature of the test cavity 22 is adjusted by cold air.

[0058] In some embodiments, the environmental component 18 includes a humidity regulating device 42 and a detection device 36, the control component 20 electrically connects the humidity regulating device 42 and the detection device 36, the detection device 36 is used to detect the humidity of the test chamber 22, and the control component 20 is used to control the operation of the humidity regulating device 42 according to the test instructions and the humidity of the test chamber 22.

[0060] Specifically, the detection device 36 may include a humidity detection device. Figure 3 In the embodiment, the humidity detection device can be installed on the back plate of the test cavity 12. The test instruction can include the target humidity of the test cavity 22. The control component 20 controls the humidity adjustment device 42 to operate according to the difference between the current humidity of the test cavity 22 detected by the detection device 36 and the target humidity, so that the current humidity of the test cavity 22 is equal to or close to the target humidity of the test cavity 22. It can be understood that the detection device 36 is not limited to being installed on the back plate of the test cavity 12, and can also be installed at other positions of the test cavity 12, which is not specifically limited here.

[0061] exist Figure 3 In the embodiment, the humidity regulating device 42 can be installed on the back plate of the test cavity 12, and the humidity regulating device 42 includes a humidifying device, and the humidifying device includes a water tank 44 and a spray port 46. The humidity regulating device 42 can atomize the water in the water tank 44, and then spray the atomized water to the test cavity 22 through the spray port 46. In one embodiment, the humidity regulating device 42 can also include a dehumidifying device. The dehumidifying device is used to reduce the humidity of the test cavity 22. It can be understood that the humidity regulating device 42 is not limited to being installed on the back plate of the test cavity 12, and can also be installed at other positions of the test cavity 12, which is not specifically limited here.

[0062] exist Figure 3In the embodiment, the detection system 100 includes a humidity regulating device 42 and a temperature regulating device 34. The fan can speed up the air flow rate of the test chamber 22, so that the temperature and humidity of the test chamber 22 quickly tend to be uniform, which is conducive to improving the detection efficiency. The detection device 36 is a temperature and humidity detection device. When testing, the device to be tested is placed in the test chamber 22, and the radiation anti-interference ability of the device to be tested can be detected by turning on the detection system 100. If the working environment of temperature and humidity needs to be tested, for example: the operator can set the temperature to 65°C and the humidity to 75% on the control panel 28, and the detection system 100 can adjust the temperature and humidity of the test chamber 22 according to the operator's input. When the detection device 36 detects that the temperature and humidity reach the target value, the detection system 100 maintains operation at this fixed value. According to the design requirements, the detection system 100 supports a test environment with a temperature of 25 to 250°C and a humidity of 0 to 100%. It can also provide a detection system 100 at low temperature according to user needs, and support the ability to operate in a special test environment of -65 to 500°C.

[0063] In some embodiments, the detection system 100 further includes a communication module 48, the control component 20 is electrically connected to the communication module 48, and the communication module 48 is used to send the detection result of the device under test to a preset terminal.

[0064] In this way, it is convenient for the operator to check the test results of the device under test at any time.

[0065] Specifically, the preset terminal includes but is not limited to cloud servers, mobile phones, tablet computers, personal computers and other terminals. Optionally, the preset terminal can be pre-bound to the detection system 100. When the detection is completed or the detection result of the device to be tested is obtained, the detection system 100 can use the communication module 48 to send the detection result to the preset terminal, so that the operator can understand the detection result of the device to be tested through the preset terminal. The operator does not need to be on duty at the test site, which improves the user experience. The communication module 48 can communicate with the preset terminal in a wired or wireless manner, which is not specifically limited here.

[0066] exist Figure 2 In the embodiment, the communication module 48 is installed on the control panel 28 . It can be understood that in other embodiments, the communication module 48 can also be installed at other positions of the detection system 100 , and is not limited to being installed on the control panel 28 .

[0067] Furthermore, the detection system 100 can store the detection results of the device under test locally.

[0068] In some embodiments, the detection system 100 includes a control panel 28, the control component 20 is installed on the control panel 28, and the control panel 28 includes a display screen 50, which is used to display at least one of the power, frequency and phase of the radio frequency signal and at least one of the target temperature and target humidity of the test cavity 22, and display at least one of the current temperature and current humidity of the test cavity 22.

[0069] In this way, it is convenient for on-site operators to understand the test status.

[0070] Specifically, in one embodiment, the test instruction includes the power, frequency and phase of the RF signal, and the target humidity and target temperature of the test cavity 22. The display screen 50 can display the power, frequency and phase of the RF signal, the target humidity and target temperature of the test cavity 22, and the current temperature and current humidity of the test cavity 22, so that the on-site operator can fully understand the test status.

[0071] In one embodiment, the display screen 50 can display the power, frequency and phase of the radio frequency signal, the target humidity of the test cavity 22, and the current humidity of the test cavity 22. Other embodiments are not listed here one by one.

[0072] Optionally, the display screen 50 may be a touch screen, and the operator may input relevant instructions through the touch screen, and the control panel 28 controls the operation of the detection system 100 according to the instructions, such as controlling the start and stop of corresponding functions.

[0073] In some embodiments, the detection system 100 includes an electrical chamber 52 and a heat dissipation assembly 54 . The electrical chamber 52 is located outside the test cavity 22 . The heat dissipation assembly 54 and the RF module 16 are located inside the electrical chamber 52 . The heat dissipation assembly 54 is used to dissipate heat for the RF module 16 .

[0074] In this way, it is possible to avoid the temperature of the RF module 16 increasing and thus reducing the accuracy of the RF module 16 in adjusting the RF signal.

[0075] Specifically, the RF module 16 needs to output RF signals when working, and its temperature rises quickly. When the temperature of the RF module 16 is high, the internal components of the RF module 16 are affected by the high temperature, and the accuracy of regulating the RF signal will be reduced. By setting the heat dissipation component 54, when the temperature of the RF module 16 exceeds the temperature threshold, the heat dissipation component 54 can be started to dissipate heat for the RF module 16, thereby ensuring the accuracy of the RF module 16 in regulating the RF signal. At the same time, it can also prevent the components of the RF module 16 from aging too quickly due to excessive temperature, thereby reducing its failure rate and extending the service life of the RF module 16.

[0076] In one embodiment, the heat dissipation component 54 can use liquid cooling to dissipate heat from the RF module 16. In one embodiment, the heat dissipation component 54 can use air cooling to dissipate heat from the RF module 16. In one embodiment, the heat dissipation component 54 can use liquid cooling and air cooling to dissipate heat from the RF module 16.

[0077] The antenna assembly 14 may also be at least partially disposed in the electrical chamber 52, and the heat dissipation assembly 54 may also dissipate heat for the antenna assembly 14. It is understandable that the heat dissipation assembly 54 may dissipate heat for other components in the electrical chamber 52 in addition to dissipating heat for the RF module 16 and the antenna assembly 14.

[0078] In some embodiments, the heat dissipation assembly 54 includes an air guide 56 and a heat dissipation motor 58 . The air guide 56 covers the RF module 16 . The air guide 56 is provided with an air inlet 60 and an air outlet 62 . The air inlet 60 is provided corresponding to the heat dissipation motor 58 .

[0079] In this way, the heat dissipation component 54 can dissipate heat from the RF module 16 by means of air cooling.

[0080] Specifically, the heat dissipation motor 58 can provide wind when working. The wind blown by the heat dissipation motor 58 enters the interior of the air guide 56, which can take away the heat of the RF module 16 and cool it down. The air inlet 60 of the air guide 56 is arranged corresponding to the heat dissipation motor 58 so that the heat dissipation motor 58 can send the generated wind into the air guide 56. After the wind takes away the heat of the RF module 16, it can be discharged from the air outlet 62 of the air guide 56, thereby reducing the temperature of the RF module 16 and the electrical room 52.

[0081] exist Figure 2 In the figure, the air guide 56 includes an air inlet end 64 and an air outlet end 66. The air inlet end 64 is provided with an air inlet 60, and the air outlet end 66 is provided with an air outlet 62. The area of ​​the air inlet 60 is larger than the area of ​​the air outlet 62. Along the direction from the air inlet end 64 to the air outlet end 66, the internal flow channel of the air guide 56 is in a gradually contracting shape, so that the wind can be accelerated in the air guide 56, so as to speed up the removal of heat from the RF module 16 and other components and parts, and improve the heat dissipation efficiency.

[0082] The detection system 100 also includes a power supply module 68 , which is disposed above the air guide 56 . The power supply module 68 can be thermally connected to the air guide 56 , and the heat dissipation assembly 54 can dissipate heat from the power supply module 68 through the air guide 56 .

[0083] The power supply module 68 is electrically connected to various components and parts of the detection system 100, including but not limited to the RF module 16, the control panel 28, the heat dissipation component 54, the environmental component 18, etc. The power supply module 68 can also be electrically connected to the socket of the test cavity 22, and the power plug of the device under test can be inserted into the socket, so that the power supply module 68 provides the device under test with the power (direct current or alternating current) required for operation, so that the device under test can work, thereby detecting the anti-electromagnetic interference capability of the device under test.

[0084] In summary, compared with large systems such as microwave darkrooms and TEM cells used in related technologies, the detection system 100 of the embodiment of the present invention has a simple structure and miniaturization, which greatly reduces the system cost. Moreover, the entire detection system 100 is easy to move and occupies a small space. It can detect the EMS performance of the device under test by simulating a complex electromagnetic interference environment. At the same time, the detection process is automated, and the operator does not need to keep watching, which greatly improves work efficiency.

[0085] The test chamber 22 can be made to have different volume sizes to adapt to different detection scenarios. In some examples, the volume of the test chamber 22 is 35L (liters), 70L or 150L, ​​which can be used to place devices of different sizes to be tested, expand the range of detection objects of the detection system 100100, and is also easy to carry. The outer dimensions of the 70L detection system 100 can be 600mm*600mm*570mm. However, the present design is not limited to this. In other embodiments, the volume of the test chamber 22 can also be configured to other values, which is not limited to this. Further optionally, the spatial dimensions of the test chamber 22 can be 350mm*340mm*320mm, or 480mm*420mm*360mm, or 650mm*600*400mm, which can be used to place devices of different sizes to be tested. However, the present design is not limited to this. In other embodiments, the spatial dimensions of the test chamber 22 can also be customized to meet different test requirements, which is not specifically limited to this.

[0086] Please refer to Figure 4 A detection method according to an embodiment of the present invention is used to detect a device to be tested, and the detection method comprises:

[0087] Step 101, according to the test instruction, the RF module 16 is controlled to output a RF signal and the environmental component 18 is controlled to adjust at least one of the temperature and humidity of the test chamber 22, and the RF signal is fed into the test chamber 22 through the antenna component 14 and radiated to the device under test located in the test chamber 22;

[0088] Step 103: Obtain and save the test result of the device under test.

[0089] In the above detection method, the RF signal emitted by the RF module 16 can be fed into the test cavity 22 via the antenna assembly 14 to radiate the RF signal to the device under test. The environmental assembly 18 can adjust at least one of the temperature and humidity of the test cavity 22, thereby more completely simulating the use scenarios of the device under test in various working conditions.

[0090] Specifically, the test instruction may be generated by the control panel 28 in response to a user operation, or may be generated according to a default operation of the detection system 100 .

[0091] It should be noted that the above explanation of the implementation method and beneficial effects of the detection system 100 is also applicable to the detection method of this embodiment, and will not be elaborated here in detail to avoid redundancy.

[0092] In certain embodiments, see Figure 5 , the detection method also includes:

[0093] Step 105: Send the detection result of the device to be tested to a preset terminal.

[0094] In this way, it is convenient for the operator to check the test results of the device under test at any time.
