[0055] Please refer to Figure 2 and Figure 3The test device 30 includes a test cavity 302, a radio frequency module 304, an antenna assembly 306 and a communication module 308. The radio frequency module 304 is electrically connected to the antenna assembly 306. A test cavity 310 is provided in the test cavity 302. The test cavity 310 is used to accommodate the device under test. In the EMS test, the radio frequency module 304 is used to output radio frequency signals, and the antenna assembly 306 feeds the radio frequency signals into the test cavity 310 to form an electromagnetic interference environment for the device under test, so as to test the electromagnetic anti-interference capability of the device under test.

[0056] The communication module 308 can be connected to the host computer 20 and the server 40 for communication. In one embodiment, the communication module 308 can be connected to the host computer 20 for communication via a data line. In one embodiment, the communication module 308 can be connected to the server 40 for communication via a router.

[0057] exist Figure 3 In the embodiment, the test cavity 302 is in the shape of a rectangular parallelepiped, and the test cavity 310 is also in the shape of a rectangular parallelepiped, and the device to be tested can be accommodated in the test cavity 310. It can be understood that the shapes of the test cavity 302 and the test cavity 310 are not limited to the rectangular parallelepiped, and can also be other regular or irregular shapes, which are not specifically limited here. Optionally, the test cavity 302 is made of a material having the ability to shield radio frequency signals, such as the test cavity 302 can be a metal cavity, and further, the test cavity 302 can include a body made of plastic material and a metal layer covering the surface of the body to reduce manufacturing costs and reduce weight.

[0058] In one embodiment, the device to be tested may include but is not limited to a control board, a display screen, a chip, a circuit board or an electronic device, which is not specifically limited herein.

[0059] In one example, the size of the test chamber 302 of the embodiment of the present invention is within 3 meters * 3 meters * 3 meters (length * width * height), and further, the size of the test chamber 302 is within 2.5 meters * 2.5 meters * 2.5 meters.

[0060] 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 304 may include a transmitter and a receiver. The transmitter includes 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 into the test cavity 310. The transmitter may adjust 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 into the test cavity 310 is close to the target power (set power) or equal to the target power.

[0061] The reflected power detection circuit is used to detect the power of the RF signal reflected by the test cavity 310. The RF module 304 can determine the energy of the RF signal absorbed by the device under test based on the data fed back by the incident power detection circuit and the reflected power detection circuit.

[0062] In the EMI test, the receiver can receive the electromagnetic wave signal radiated from the device under test in the test cavity 310 to the outside through the antenna assembly 306, and convert the electromagnetic wave signal into a voltage signal.

[0063] Please refer to Figure 3 The antenna assembly 306 may include an antenna 312 and a base 314, wherein the base 314 is mounted on a side plate (such as a top plate) of the test cavity 302, and the antenna 312 is mounted on the base 314. Optionally, the antenna 312 may extend into the test cavity 310 in whole or in part. The antenna 312 may be an array antenna 312 or other types of antennas 312, which are not specifically limited herein. The number of antennas 312 may be one, two, or more than two, which are not specifically limited herein. Optionally, the antenna 312 is a broadband antenna 312.

[0064] exist Figure 2 and Figure 3 In the embodiment, the test device 30 further includes a control panel 316 installed on the test cavity 302, and the control panel 316 is electrically connected to the RF module 304. The control panel 316 may include operating components such as buttons and a touch screen, and an operator may set parameters of the RF signal through the operating components, such as the frequency, phase, power, etc. of the RF signal, so as to generate a variety of RF signals within a certain frequency band, and to simulate complex electromagnetic interference scenarios of the device under test in an actual environment.

[0065] The test device 30 further includes a door body 318, an electrical room 320 and a heat dissipation assembly 322. An opening 324 is provided on one side of the test chamber 310. The door body 318 is rotatably mounted at the opening 324 to open or close the opening 324. When the door body 318 opens the opening 324, the operator can take and place the device to be tested. When the door body 318 is closed, the test can be performed. The door body 318 is used to prevent the RF signal from leaking from the test chamber 310 to the outside of the test chamber 302, thereby improving the safety of the test process.

[0066] The electrical chamber 320 is located outside the test chamber 310, and the heat dissipation component 322 and the RF module 304 are located in the electrical chamber 320. The heat dissipation component 322 is used to dissipate heat for the RF module 304. In one embodiment, the heat dissipation component 322 can dissipate heat for the RF module 304 by means of liquid cooling. In one embodiment, the heat dissipation component 322 can dissipate heat for the RF module 304 by means of air cooling. In one embodiment, the heat dissipation component 322 can dissipate heat for the RF module 304 by means of liquid cooling and air cooling.

[0067] The antenna assembly 306 may also be at least partially disposed in the electrical chamber 320, and the heat dissipation assembly 322 may also dissipate heat for the antenna assembly 306. It is understandable that the heat dissipation assembly 322 may dissipate heat for other components in the electrical chamber 320 in addition to dissipating heat for the RF module 304 and the antenna assembly 306.

[0068] exist Figure 3 In the figure, the heat dissipation assembly 322 includes an air guide 326 and a heat dissipation fan 328. The air guide 326 covers the RF module 304. The air guide 326 is provided with an air inlet 330 and an air outlet 332. The air inlet 330 is arranged corresponding to the heat dissipation fan 328. In this way, the heat dissipation assembly 322 can dissipate heat from the RF module 304 by air cooling.

[0069] The test device 30 also includes a power supply module 334, which is electrically connected to the RF module 304 and the heat dissipation fan 328. The power supply module 334 is located above the air guide 326 and is thermally connected to the air guide 326. In this way, the power supply module 334 can be cooled to ensure that the power supply module 334 operates within a normal temperature range. The power supply module 334 is electrically connected to various components and parts of the test device 30, including but not limited to the RF module 304, the control panel 316, the heat dissipation component 322, etc. A socket is also provided in the test cavity 310, and the power supply module 334 can also be electrically connected to the socket in the test cavity 310. The power supply plug of the device to be tested can be inserted into the socket, so that the power supply module 334 provides the device to be tested with the electrical energy (DC and / or AC) required for operation, so that the device to be tested can work, thereby testing the anti-electromagnetic interference capability of the device to be tested.

[0070] In the EMS test, the transmitter of the RF module 304 generates a corresponding RF signal according to the set RF signal parameters, and the antenna assembly 306 feeds the RF signal into the test cavity 310 to generate electromagnetic interference to the device under test.

[0071] The test device 30 may further include a controller 336, which may control the operation of the test device 30. Specifically, the controller 336 is used to obtain characteristic information of the device under test, which includes but is not limited to parameters such as volume and shape of the device under test.

[0072] Furthermore, during the EMS test process, the controller 336 can determine whether the working state of the device under test is normal or abnormal by collecting the status information of the device under test. Specifically, the controller 336 can determine by collecting at least one of the image of the device under test, the sound emitted by the device under test, and the temperature of the device under test. For example, the controller 336 can collect the image of the device under test through the camera 344, and identify whether the device under test has abnormal phenomena such as flashing screen, flower screen, black screen, etc. through image recognition technology. The controller 336 can collect the sound emitted by the device under test through the sound sensor to determine whether the device under test has abnormal phenomena such as component cracking. The controller 336 can collect the temperature of the device under test through the temperature sensor to determine whether the device under test has abnormal phenomenon of over-temperature.

[0073] After the EMS test is completed, the controller 336 generates post-EMS test data, which includes parameters (frequency, phase, power) of all RF signals used in the EMS test process, as well as whether the working state of the device under test is abnormal or normal under each RF signal, and abnormal conditions under abnormal conditions.

[0074] After the EMI test is completed, the controller 336 generates EMI post-test data, which includes parameters (frequency, phase, power) of the electromagnetic waves radiated by the device under test.

[0075] The test device 30 sends the post-test data to the host computer 20, which is installed with the host computer software. The host computer software uses the post-test data to form a test result. The test result may include data forms such as graphics and tables and test information. The test information includes data such as temperature, humidity, air pressure, and test time in the test chamber 310. The output of the test result can be displayed through the graphical user interface of the host computer software. The test information can be collected by the relevant sensors and timing units of the test device 30.

[0076] The case library of the server 40 can be preset and stored in the server 40. The case library includes the industry in which the equipment is located, the type of equipment, and abnormal conditions that occur during the test of the equipment and corresponding rectification information. The server 40 can update the case library according to the input new case.

[0077] After the test is completed, the test device 30 uploads the characteristic information of the device under test and the post-test data to the server 40. The server 40 matches the post-test data with the data in the case library based on the characteristic information of the device under test, and then obtains the corresponding rectification information. The server 40 sends the rectification information to the terminal device 50. The rectification information can be measures and / or suggestions taken to eliminate abnormal conditions that occur during the test of the device under test.

[0078] The terminal device 50 can be connected to the server 40 in a wired or wireless manner, which is not specifically limited here. The terminal device 50 includes but is not limited to a mobile phone, a tablet computer, a personal computer, a wearable smart device, etc. In one embodiment, the host computer 20 and the terminal device 50 can be the same device. In one embodiment, the host computer 20 and the terminal device 50 can be different devices. The terminal device 50 can save the rectification information, which is convenient for subsequent engineers to view the rectification information and rectify the device under test.

[0079] In some embodiments, the testing device 30 includes a voice unit 338, which includes a speaker 340 and a microphone 342. The voice unit 338 is used to play the voice of the remote engineer using the speaker 340 and to collect the voice of the on-site operator using the microphone 342 to achieve voice dialogue between the remote engineer and the on-site operator.

[0080] In this way, on-site operators can have voice conversations with remote engineers.

[0081] Specifically, in one embodiment, the speaker 340 and the microphone 342 can be installed on the control panel 316. The remote worker can be a customer engineer, and the remote engineer can hold the terminal device 50. After the terminal device 50 establishes a communication connection with the test device 30, the remote worker can input voice information on the terminal device 50 to describe the test requirements and the basic characteristics of the device under test (such as purpose, principle, etc.), and the voice information is transmitted to the test device 30 via the server 40. The voice unit 338 uses the speaker 340 to play the voice information of the remote engineer. The test site operator can input voice information on site, and the microphone 342 collects the voice information of the site operator. The test device 30 sends the voice information of the site operator to the server 40, which is transmitted to the terminal device 50 by the server 40. The terminal device 50 plays the voice information of the site operator, thereby realizing a voice dialogue between the site operator and the remote engineer, communicating the test in real time, and improving the test efficiency.

[0082] The test requirements may include the parameters required for the test. For example, for EMS testing, the test requirements may include the test frequency band, phase and power of the RF signal, etc. For EMI testing, the test requirements may include the frequency band of the collected electromagnetic waves, etc.

[0083] It is understandable that in other implementations, the remote engineer may also hold other devices to establish a communication connection with the test device 30 , which is not limited to the terminal device 50 .

[0084] In some embodiments, the test device 30 includes a test chamber 302, a controller 336, and a camera 344. The test chamber 302 is provided with a test chamber 310, and the test chamber 310 is used to place the device under test. The controller 336 is electrically connected to the camera 344, and the camera 344 is used to collect an image of the device under test. The controller 336 is used to process the image of the device under test to obtain characteristic information of the device under test, and based on the characteristic information of the device under test, call the corresponding test configuration to perform electromagnetic compatibility test on the device under test.

[0085] In this way, the corresponding test configuration can be automatically called according to the characteristic information of the device under test, thereby improving the test efficiency.

[0086] Specifically, the camera 344 can be installed in the test cavity 310, or outside the test cavity 310. Optionally, the camera 344 can be placed inside the electromagnetic shielding member to reduce the impact of the radio frequency signal on the camera 344. The camera 344 can collect images of the device under test in the test cavity 310 through the light transmission hole.

[0087] The controller 336 may process the image of the device under test using image recognition technology to obtain feature information of the device under test, and the feature information of the device under test may include but is not limited to the volume and shape of the device under test. The image recognition technology may include technology for processing images using a deep neural network.

[0088] The test configuration includes the parameters of the radio frequency signal used in the EMS test process and the parameters of the electromagnetic wave signal collected in the EMI test process. The correspondence between the test configuration and the characteristic information of the device under test can be pre-calibrated and stored. During the test process, by obtaining the characteristic information of the device under test, the corresponding test configuration can be obtained by using the pre-stored correspondence and the characteristic information of the current device under test.

[0089] In some implementations, the server 40 is used to determine the type of the device under test based on the characteristic information of the device under test, and analyze the post-test data to obtain rectification information corresponding to the type of the device under test in the case library.

[0090] In this way, rectification information corresponding to the type of equipment under test can be obtained.

[0091] Specifically, the server 40 can determine the type of the device under test based on the characteristic information of the device under test, for example, it can be determined whether the device under test is a control board, a chip, or a display screen. During the test process, different types of devices under test may have the same or similar abnormal conditions, and the corresponding rectification information is also different. The server 40 can determine the type of the device under test, and then find the rectification information that matches the type of the device under test in the case library, and then use the post-test data to further match the rectification information that matches the type of the device under test to obtain the final rectification information.

[0092] For example, the case library includes devices such as chips and display screens. The abnormal conditions are freezes and read / write errors. The rectification information for chip freezes is to repair the poor contact of the power pins, and the rectification information for chip read / write errors is to repair the poor contact of the input / output interface. The rectification information for display freezes is to adjust the spacing of the drive line layout, and the rectification information for display read / write errors is to adjust the cache size.

[0093] When testing the chip, the abnormal situation of the chip is a freeze. The server 40 obtains the characteristic information of the device under test, determines that the device under test is a chip, and then finds the rectification information corresponding to the chip in the case library, and then obtains from the post-test data that the abnormal situation of the chip is a freeze, and further determines in the rectification information corresponding to the chip that the rectification information is the rectification information of the chip freeze: repair the poor contact of the power pin.

[0094] It should be noted that the above examples are made to facilitate understanding of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0095] In some implementations, the terminal device 50 is also used to save and display test results.

[0096] In this way, it is convenient for the user of the terminal device 50 to view the test results.

[0097] Specifically, in one embodiment, the host computer 20 and the terminal device 50 are different devices. The host computer 20 can send the test result to the test device 30, the test device 30 uploads the test result to the server 40, the server 40 transmits the test result to the terminal device 50, and the terminal device 50 saves and displays the test result.

[0098] In one embodiment, the host computer 20 can be connected to the server 40 for communication, and the host computer 20 can upload the test results to the server 40, and the server 40 transmits the test results to the terminal device 50. In one embodiment, the host computer 20 can be directly connected to the terminal device 50 for communication, and the host computer 20 directly transmits the test results to the terminal device 50.

[0099] The user of the terminal device 50 can view the test results and rectification information on the terminal device 50 to facilitate subsequent rectification of the device under test.

[0100] In some embodiments, the terminal device 50 is further configured to obtain a subscription instruction and send the subscription instruction to the server 40. The subscription instruction includes a device type and a request to obtain rectification information corresponding to the device type. The server 40 is configured to parse the subscription instruction, obtain the device type and the request, and when rectification information of the device under test that matches the device type is obtained, the obtained rectification information is sent to the terminal device 50.

[0101] In this way, users can subscribe to rectification information according to their own needs.

[0102] Specifically, the terminal device 50 is installed with a test application (APP). The user can open the test APP on the terminal device 50, enter a subscription instruction in the graphical user interface of the test APP, and the terminal device 50 obtains the subscription instruction and sends the subscription instruction to the server 40. The subscription instruction includes a device type and a request to obtain rectification information corresponding to the device type. For example, when a user needs to subscribe to rectification information corresponding to a chip, the user can select the device type as a chip in the subscription interface of the test APP, and then click the "Subscribe" button on the interface, and the terminal device 50 can generate a subscription instruction.

[0103] Furthermore, the device types may include paid types and free types. For paid types, the test APP may set a charging interface. When the user selects a subscription of a paid type in the subscription interface, the terminal device 50 may display the charging interface. After the user successfully pays, the terminal device 50 may send a subscription instruction to the server 40. When the user selects a free type in the subscription interface, the charging interface is not displayed. After the user completes the selection, the user clicks the "Subscribe" button in the interface, and the terminal device 50 may generate a subscription instruction and send the subscription instruction to the server 40.

[0104] The server 40 obtains the subscription instruction, parses the subscription instruction, and obtains the equipment type and the acquisition request of the rectification information corresponding to the equipment type. After the server 40 obtains the equipment type and the acquisition request of the rectification information corresponding to the equipment type, the server 40 searches in the current case library. If the rectification information corresponding to the equipment type is found, the server 40 can send the obtained rectification information to the terminal device 50.

[0105] If rectification information corresponding to the device type is not found, the server 40 may search again after a period of time, or search again after the case library is updated. When rectification information corresponding to the device type is found, the server 40 may send the acquired rectification information to the terminal device 50.
