Description

Technical Field

[0001] This utility model relates to the field of electromagnetic immunity testing technology, and in particular to an auxiliary testing system with multi-unit collaborative function. Background Technology

[0002] In electromagnetic compatibility (EMC) testing, to accurately evaluate the EUT's immunity to electromagnetic interference, it is generally necessary to add auxiliary equipment (AE) to construct a complete test system. However, existing test schemes have the following problems:

[0003] 1. The precision electronic components contained in the auxiliary device are sensitive to electromagnetic interference. During the test, they may generate abnormal responses due to interference signals emitted by the external EMS generator. Such abnormal responses will interfere with the normal operation of the device under test, resulting in distorted test results. That is, the device under test, which originally has qualified electromagnetic interference resistance, may be judged as unqualified due to the abnormal response of the auxiliary device, which prolongs the test time to a certain extent.

[0004] 2. In the surge immunity test, only the principle requirement is to "determine decoupling measures according to the protection requirements of auxiliary devices", without clearly quantifying the residual voltage control index;

[0005] 3. Although the electrical fast transient burst test specifies that the residual voltage of a 4000V interference voltage should be ≤400V after processing, conventional auxiliary devices generally cannot withstand this residual voltage. Utility Model Content

[0055] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0056] As attached Figure 1 and appendix Figure 2 As shown, this embodiment discloses an auxiliary testing system with multi-unit collaborative function to shorten testing time. It mainly includes a control module 1, an information acquisition module 2, a parameter retrieval module 3, and a protection execution module 4. The control module 1 monitors the operation of other components and the transmission of corresponding data. The data communication terminal of the control module 1 is equipped with the information acquisition module 2, the parameter retrieval module 3, and the protection execution module 4. The acquisition module 2 collects parameter information from interference signals emitted by an external EMS generator, such as peak voltage and peak current signals. The parameter retrieval module 3 retrieves corresponding processing parameters from an external cloud storage database based on the parameter information obtained by the information acquisition module 2. The protection execution module 4 processes the interference signals emitted by the external EMS generator and transmits the processed interference signals to an external auxiliary device.

[0057] In use, first connect the external EMS generator (not shown in the figure) to the external device under test (not shown in the figure), connect the external EMS generator to the information acquisition module 2, connect the external EMS generator to the protection execution module 4, and connect the protection execution module 4 to the external auxiliary device (not shown in the figure). Additionally, the operator needs to list the corresponding processing parameters based on the parameter information of the interference signal emitted by the external EMS generator. These processing parameters constitute an external cloud storage database (not shown in the figure). For example, the operator can list the following processing parameters: 1. If the peak voltage signal in the interference signal is greater than 50V and the peak current signal is greater than 0.5A, then activate... 1. If the transient protection unit 41, differential mode inductor unit 43, and common mode inductor unit 45 are activated, and ferrite unit 47 is deactivated; 2. If the peak voltage signal in the interference signal is greater than 50V and the peak current signal is less than 0.5A, then the transient protection unit 41, common mode inductor unit 45, and ferrite unit 47 are activated, and differential mode inductor unit 43 is deactivated; 3. If the peak voltage signal in the interference signal is less than 50V and the peak current signal is greater than 0.5A, then the transient protection unit 41, differential mode inductor unit 43, and ferrite unit 47 are activated, and common mode inductor unit 45 is deactivated; 4. If the peak voltage signal is less than 50V and the peak current signal is less than 0.5A, then differential mode inductor unit 43 and common mode inductor unit 45 are activated. And ferrite unit 47, turn off transient protection unit 41, etc.; then, start this embodiment, the external EMS generator sends interference signals to the external test device and the external auxiliary device respectively; then, the information acquisition module 2 can collect the peak voltage signal and peak current signal in the interference signal sent by the external EMS generator; then, the signal acquisition module sends the collected parameter information about the peak voltage signal and peak current signal to the control module 1. This design can provide the corresponding basic information for this utility model; then, the control module 1 sends the received parameter information to the parameter retrieval module 3; then, the parameter retrieval module 3 can retrieve the parameter information from the external EMS generator according to the received parameter information. The corresponding processing parameters are retrieved from the cloud storage database. Then, the parameter retrieval module 3 sends the retrieved processing parameters to the control module 1. Then, the control module 1 sends the corresponding control command to the protection execution module 4. At this time, the protection execution module 4 can change the working state of the transient protection unit 41, the differential mode inductor unit 43, the common mode inductor unit 45 and the ferrite unit 47 according to the control command, thereby processing the interference signal received by the external auxiliary device from the output terminal of the external EMS generator. This design can avoid the external auxiliary device from abnormal response due to interference signal, improve the accuracy of the test results of the device under test, and extend the service life of the auxiliary device to a certain extent.

[0058] It should be noted that: the transient protection unit 41 can absorb voltages exceeding the preset first pressure value (excessively high, medium-to-high energy voltages) in the interference signal, which corresponds to the processing parameters 1-3 in the external cloud storage database; the differential mode inductor unit 43 can absorb high-frequency signals in differential mode form in the interference signal; the common mode inductor unit 45 can absorb common mode interference signals in the interference signal; the ferrite unit 47 can absorb frequencies within the preset range in the interference signal, as well as signals exceeding the preset second pressure value (low-energy, high-frequency, high-voltage interference signals), which corresponds to the processing parameters 2-4 in the external cloud storage database. This is existing technology, and the relevant details will not be elaborated further. In addition, the output terminals of the transient protection unit 41, differential mode inductor unit 43, common mode inductor unit 45, and ferrite unit 47 are respectively equipped with status display units. These status display units include a first status display unit 42, a second status display unit 44, a third status display unit 46, and a fourth status display unit 48. That is, when the transient protection unit 41 is working, the first status display unit 42 will also be working; when the differential mode inductor unit 43 is working, the second status display unit 44 will also be working; when the common mode inductor unit 45 is working, the third status display unit 46 will also be working; and when the ferrite unit 47 is working, the fourth status display unit 48 will also be working. This design facilitates the observation of the current operating status of the transient protection unit 41, differential mode inductor unit 43, common mode inductor unit 45, and ferrite unit 47. Furthermore, by observing the operating status, the reasons for the corresponding test results generated by the external device under test can be analyzed. In other words, even if the test results of the external device under test are distorted, it will not be caused by the external auxiliary device, thus shortening the test time to a certain extent.

[0059] The specific architecture of the auxiliary testing system is as follows: It includes a control module 1, which monitors the operation of other components and the transmission of corresponding data in this embodiment; the data communication terminal of the control module 1 is equipped with an information acquisition module 2, which is used to acquire parameter information from the interference signal emitted by the external EMS generator, such as the peak voltage signal and peak current signal in the interference signal; the data communication terminal of the control module 1 is equipped with a parameter retrieval module 3, which is used to retrieve the corresponding processing parameters from the external cloud storage database based on the parameter information obtained by the information acquisition module 2; the data communication terminal of the control module 1... The communication terminal is equipped with a protection execution module 4, which processes interference signals emitted by an external EMS generator and transmits the processed interference signals to an external auxiliary device. The protection execution module 4 includes a transient protection unit 41, a differential-mode inductor unit 43, a common-mode inductor unit 45, and a ferrite unit 47. Furthermore, the output terminal of the transient protection unit 41 is equipped with a first status display unit 42, the output terminal of the differential-mode inductor unit 43 is equipped with a second status display unit 44, the output terminal of the common-mode inductor unit 45 is equipped with a third status display unit 46, and the output terminal of the ferrite unit 47 is equipped with a fourth status display unit 48. Compared with the prior art, this invention improves the accuracy of the test results of the tested device, extends the service life of the auxiliary device, and shortens the test time to a certain extent, thus possessing high practicality.

[0060] Furthermore, the first status display unit 42, the second status display unit 44, the third status display unit 46, and the fourth status display unit 48 can all be LED indicator lights. This design facilitates the observation of the working status of the corresponding components in the protection execution module 4 by the operator. Of course, the operator can also change the colors displayed by the aforementioned four LED indicator lights. For example, the LED indicator connected to the transient protection unit 41 can display red when working; the LED indicator connected to the differential mode inductor unit 43 can display orange; the LED indicator connected to the common mode inductor unit 45 can display yellow; and the LED indicator connected to the ferrite unit 47 can display cyan. This design allows the operator to quickly identify which components in the protection execution module 4 are currently working. Simultaneously, the operator can obtain the parameter information of the current interference signal, thereby analyzing the current state of the device under test. The reason for generating the corresponding test results is that the test time is shortened to a certain extent. Under normal circumstances, the first status display unit 42 is integrated on the transient protection unit 41, the second status display unit 44 is integrated on the differential mode inductor unit 43, the third status display unit 46 is integrated on the common mode inductor unit 45, and the fourth status display unit 48 is integrated on the ferrite unit 47. This design can reduce the time for the corresponding LED indicator to receive the corresponding data. For example, when the transient protection unit 41 is working, the first status display unit 42 will immediately work synchronously, which makes it convenient for the staff to observe the working status of the corresponding components in the protection execution module 4 in this embodiment.

[0061] In a specific application scenario, the transient protection unit 41 can be a TVS; wherein, the TVS is a transient suppression diode, which is a high-efficiency protection device in the form of a diode; when the two poles of the transient suppression diode are subjected to a reverse transient high-energy impact, it can change the high impedance between its two poles to a low impedance at a speed of 10 to the power of negative 12 seconds, absorbing surge power of up to several kilowatts, clamping the voltage between the two poles to a predetermined value, effectively protecting the precision components in the electronic circuit from damage by various surge pulses; therefore, the transient protection unit 41 can prevent excessively high, medium-to-high energy voltages from directly entering external auxiliary devices.

[0062] Furthermore, the differential mode inductor unit 43 can be a differential mode inductor; wherein, the differential mode inductor can utilize the high-frequency resistance characteristics of the coil itself to block the flow of high-frequency interference signals in the form of differential mode, and work together with the common mode inductor unit 45 to suppress the influence of interference signals on external auxiliary devices; in addition, the differential mode inductor is an inductor with high inductive reactance to differential mode high-frequency interference.

[0063] Furthermore, the common-mode inductor unit 45 can be a common-mode inductor. This common-mode inductor can utilize the principle of superimposing the magnetic flux of two sets of inductor coils of the same specification to generate a large inductance, which can strongly suppress the common-mode interference current signal flowing through it and minimize the common-mode interference current flowing into external auxiliary devices. In addition, the common-mode inductor is also called a common-mode choke, which is often used in the switching power supply of computers to filter common-mode electromagnetic interference signals. In board design, the common-mode inductor can also play the role of EMI filtering, that is, suppressing the outward radiation of electromagnetic waves generated by high-speed signal lines.

[0064] Furthermore, the ferrite unit 47 can be a ferrite bead or a ferrite ring; wherein, the ferrite bead or ferrite ring can utilize the high permeability and high high-frequency loss characteristics of ferrite devices to effectively suppress low-energy, high-frequency, and high-voltage interference signals from entering the external auxiliary device.

[0065] Additionally, staff can modify the architecture of the aforementioned protection execution module 4. For example, they can set a first enable switch (not shown in the figure) at the corresponding position of the transient protection unit 41, a second enable switch (not shown in the figure) at the corresponding position of the differential mode inductor unit 43, a third enable switch (not shown in the figure) at the corresponding position of the common mode inductor unit 45, and a fourth enable switch (not shown in the figure) at the corresponding position of the ferrite unit 47. Specifically, the first enable switch is the bypass electronic jumper of the transient protection unit 41 (automatically switched in conjunction with the control command issued by the control module 1, rather than manually operated). When the first enable switch is closed, a low-impedance bypass circuit is formed, preventing the transient protection unit 41 from participating in the processing of interference signals. When the first enable switch is open, interference signals can only pass through the transient protection unit 41, allowing the transient protection unit 41 to participate in the processing of interference signals. The second enable switch is a bypass electronic jumper for the differential mode inductor unit 43 (automatically switched in conjunction with control commands issued by the control module 1, rather than manually operated). When the second enable switch is closed, a low-impedance bypass circuit is formed, preventing the differential mode inductor unit 43 from participating in the processing of interference signals. When the second enable switch is open... Interference signals flowing out through transient protection unit 41 can only pass through differential mode inductor unit 43, allowing differential mode inductor unit 43 to participate in interference signal processing. The third enable switch is a bypass electronic jumper for common mode inductor unit 45 (automatically switched with control commands issued by control module 1, rather than manually operated). When the third enable switch is closed, a low-impedance bypass circuit is formed, preventing common mode inductor unit 45 from participating in interference signal processing. When the third enable switch is open, interference signals flowing out through differential mode inductor unit 43 can only pass through common mode inductor unit 45, allowing common mode inductor unit 45 to participate in interference signal processing. The interference signal processing involves a fourth enable switch, which is an electronic jumper bypassing the ferrite unit 47 (automatically switched in conjunction with control commands issued by the control module 1, rather than manually operated). When the fourth enable switch is closed, a low-impedance bypass circuit is formed, preventing the ferrite unit 47 from participating in the interference signal processing. When the fourth enable switch is open, the interference signal flowing out through the common-mode inductor unit 45 can only pass through the ferrite unit 47, allowing the ferrite unit 47 to participate in the interference signal processing. This is prior art, and the general content can be found in the existing patent with publication number CN114487637A.

[0066] In a specific application scenario, the data communication terminal of the control module 1 is equipped with a heat dissipation module 5; under normal circumstances, the aforementioned information acquisition module 2 is internally equipped with a temperature detection unit (not shown in the figure).

[0067] In practical use, the temperature detection unit in the information acquisition module 2 can monitor the temperature of the external environment in real time. Then, the information acquisition module 2 can transmit the acquired temperature data to the control module 1. Under normal circumstances, the staff can also list the corresponding heat dissipation parameters in the external cloud storage database. That is, when the external environment reaches a certain temperature, the heat dissipation module 5 is activated to achieve the cooling effect. Then, the control module 1 forwards the received temperature data to the parameter retrieval module 3. Next, the parameter retrieval module 3 retrieves the corresponding heat dissipation parameters from the external cloud storage database based on the temperature data. Then, the parameter retrieval module 3 transmits the heat dissipation parameters to the control module 1. The control module 1 sends the corresponding control command to the heat dissipation module 5 based on the received heat dissipation parameters. At this time, the heat dissipation module 5 begins to execute the control command issued by the control module 1. In a specific application scenario, the heat dissipation module 5 can be a smart air conditioner. That is, the smart air conditioner can automatically adjust the temperature of the emitted cold air according to the control command issued by the control module 1. This design can reduce the temperature of the external environment in this embodiment and, to a certain extent, ensure the accuracy of the test results of this embodiment.

[0068] Of course, when the staff actually implements it, the heat dissipation module 5 can be designed as a cooling fan and integrated into the transient protection unit 41, the differential mode inductor unit 43, the common mode inductor unit 45 and the ferrite unit 47. Under normal circumstances, the control module 1 can wirelessly control the working status and frequency of the cooling fan. With the help of the information acquisition module 2, the control module 1, the parameter retrieval module 3 and the external cloud storage database, the cooling fan can perform heat dissipation operation on the transient protection unit 41, the differential mode inductor unit 43, the common mode inductor unit 45 and the ferrite unit 47.

[0069] This embodiment considers one scenario, and the specific solution is as follows: A host computer 6 is set up at the data communication terminal of the control module 1. When the staff feels that the processing parameters in the external cloud storage database do not conform to the current test scenario, they can input data to the control module 1 through the host computer 6 to correct the corresponding processing parameters. Normally, the control module 1 can directly send the corresponding data to the external cloud storage database to replace the original processing parameters. This design realizes the correction operation of the corresponding processing parameters. Simultaneously, the control module 1 sends the corrected information to the parameter retrieval module 3, allowing the parameter retrieval module 3 to retrieve the corrected processing parameters from the external cloud storage database based on the parameter information subsequently received from the information acquisition module 2. The control module 1 can generally feed back the data it receives to the host computer 6, meaning that the staff can obtain the data generated during the operation of this embodiment through the host computer 6, thus providing convenience for the staff to analyze the corresponding data. A mobile communication device 61 is wirelessly set up at the data communication terminal of the host computer 6. This mobile communication device 61 can be a smartphone. The staff can remotely send data to the control module 1 to correct the corresponding processing parameters through the host computer 6 via the smartphone, thereby achieving the purpose of remote control and improving work efficiency to a certain extent. An LED display 62 is set at the data communication terminal of the host computer 6. The LED display 62 can display the data received by the host computer 6 from the control module 1. This design makes it easier for staff to find the corresponding data more quickly and accurately, and then analyze and process the data to find out the reason why the device under test produces the corresponding test results, which shortens the test time to a certain extent. An alarm 7 is installed at the data communication terminal of control module 1. This alarm 7 can be an audible and visual alarm. If, based on feedback from protection execution module 4, control module 1 detects that several components among transient protection unit 41, differential mode inductor unit 43, common mode inductor unit 45, and ferrite unit 47 are not functioning properly, control module 1 will send a start command to the audible and visual alarm to alert nearby personnel to replace or maintain the components in protection execution module 4. For example, if control module 1 sends an start command to transient protection unit 41, but transient protection unit 41 is not working, and the first status display unit 42 is also not working, control module 1 will alert nearby personnel to perform corresponding replacement or maintenance operations via the audible and visual alarm. Of course, during the replacement or maintenance process, personnel need to stop the corresponding testing work to avoid endangering their personal safety. The circuit structures described above are all within the scope of existing technology. The innovation of this utility model lies only in the optimization design of the overall system architecture and does not involve any improvement to the specific circuit structure.

[0070] The above description is merely an optional embodiment of this utility model and is not intended to limit the utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
