In addition, the method abandons high-cost rectification strategies such as sleeving a magnetic ring on a cable, completely shielding the whole machine and the like, provides rectification strategies which are convenient to introduce in mass production and have lower cost, and better improves the electromagnetic compatibility of electronic equipment. Moreover, when the electromagnetic radiation disturbance test on the electronic equipment fails, the positioning rectification is needed; according to the scheme recorded in the method, a tester can quickly position different electromagnetic radiation disturbance problems and clearly modify the thought, so that the electronic equipment to be tested can quickly pass the electromagnetic radiation disturbance test to complete the electromagnetic compatibility authentication.

In an exemplary embodiment, the electromagnetic radiation disturbance test parameters of the target object include at least one of: frequency of electromagnetic radiation exceeding frequency points, signal cables, electromagnetic radiation exceeding frequency points, power lines and shielding structures. The target object in the method comprises electronic equipment. Namely, the electromagnetic radiation disturbance test parameters of the electronic equipment in the method comprise at least one of the following parameters: frequency of electromagnetic radiation exceeding frequency point, signal cable, electromagnetic radiation exceeding frequency point, power line and case structure.

As an example, the preset test sequence may be set as follows: and sequentially testing the frequency of the electromagnetic radiation standard exceeding frequency point, the signal cable, the electromagnetic radiation standard exceeding frequency point, the power line and the chassis structure.

In an exemplary embodiment, if the electronic device fails the electromagnetic radiation disturbance test, the frequency of electromagnetic radiation superstandard frequency points in the electronic device is tested, and whether a frequency doubling relationship exists between the electromagnetic radiation superstandard frequency points in the electronic device is determined. And determining the frequency points exceeding the standard with the frequency multiplication relation as frequency point regular disturbance, and determining the frequency points exceeding the standard without the frequency multiplication relation as frequency point irregular disturbance. Setting an adjustment and modification strategy according to regular disturbance or irregular disturbance of the frequency points; and adjusting the electronic equipment according to the adjustment and modification strategy, and performing the electromagnetic radiation disturbance test on the electronic equipment again after the adjustment until the electronic equipment passes the electromagnetic radiation disturbance test. According to the method and the device, whether the frequency of the electromagnetic radiation standard-exceeding frequency point in the electronic equipment is regular or not is judged by comparing the reference fundamental frequency with the reference fundamental frequency of each signal of the circuit board, so that the electromagnetic disturbance is divided into frequency point regular disturbance and frequency point irregular disturbance. By way of example, through analysis of the frequencies of the radiation disturbance exceeding frequency points, whether a certain frequency doubling relation exists between the frequencies of the exceeding frequency points is judged. If frequency multiplication relation exists, the frequency points exceeding the standard are regarded as regular points, and if the frequency of the frequency points exceeding the standard is 375MHz, 625MHz and 750MHz which are respectively 3 frequency multiplication, 5 frequency multiplication and 6 frequency multiplication of 125MHz of the gigabit network clock, the frequency points exceeding the standard corresponding to 375MHz, 625MHz and 750MHz are regarded as regular points.

According to the records, the method also comprises the steps of obtaining the regular disturbance of the frequency points and determining a transmitting source according to the signal fundamental frequency of the electronic equipment; adding a filter design to the determined emission source, and then performing an electromagnetic radiation disturbance test on the electronic equipment; and if the test fails, performing the filter design again, and continuing to perform the electromagnetic radiation disturbance test on the electronic equipment until the electronic equipment passes the electromagnetic radiation disturbance test. In the embodiment, a set of electromagnetic radiation disturbance positioning and rectifying methods is designed by adding a filter circuit, and different flowerlike solution ideas of electromagnetic radiation disturbance problems are provided.

In an exemplary embodiment, irregular disturbance of a frequency point is obtained, and whether an electronic device has an external signal cable or not is determined; if the electronic equipment has an external signal cable, pulling out the corresponding signal cable, and judging whether the electronic equipment passes the electromagnetic radiation disturbance test; if the electronic equipment does not pass the electromagnetic radiation disturbance test after the signal cable is pulled out, analyzing the electromagnetic disturbance performance of the signal cable; and carrying out the electromagnetic radiation disturbance test again according to the corresponding analysis result; and if the test fails, performing the filter design again, and continuing to perform the electromagnetic radiation disturbance test on the electronic equipment until the electronic equipment passes the electromagnetic radiation disturbance test. Specifically, if the electromagnetic disturbance performance of the signal cable is good, the electromagnetic radiation disturbance test is performed again after a filter design is added at the port of the signal cable; and if the test fails, performing the filter design again, and continuing to perform the electromagnetic radiation disturbance test on the electronic equipment until the electronic equipment passes the electromagnetic radiation disturbance test. If the electromagnetic disturbance performance of the signal cable is not good, performing electromagnetic radiation disturbance test after adjustment according to the signal cable adjustment measures; and if the test fails, performing the filter design again, and continuing to perform the electromagnetic radiation disturbance test on the electronic equipment until the electronic equipment passes the electromagnetic radiation disturbance test. Wherein the signal cable adjustment measure comprises at least one of: the signal cable shielding layer is grounded, and the differential signal wire is twisted.

In an exemplary embodiment, if the electronic device does not have an external signal cable, or the electronic device still fails the electromagnetic radiation disturbance test after the signal cable of the electronic device is unplugged; analyzing the electromagnetic radiation exceeding frequency point to determine whether the electromagnetic radiation exceeding frequency point is a low-frequency envelope or a high-frequency single point; making an adjustment strategy according to the low-frequency envelope or the high-frequency single point; and adjusting the electronic equipment according to the adjustment and modification strategy, and performing the electromagnetic radiation disturbance test on the electronic equipment again after the adjustment until the electronic equipment passes the electromagnetic radiation disturbance test. Specifically, as an example, if the frequency point with the electromagnetic radiation exceeding the standard is a high-frequency single point, the spectrometer is used in combination with a near-field probe to perform near-field measurement and positioning, and the electromagnetic radiation disturbance test is continuously performed on the electronic equipment after the filter design is added; and if the test fails, performing the filter design again, and continuing to perform the electromagnetic radiation disturbance test on the electronic equipment until the electronic equipment passes the electromagnetic radiation disturbance test. The embodiment of the application integrates a near field measurement method, designs a set of electromagnetic radiation disturbance positioning and rectifying method, and provides a flow-based solution idea of different electromagnetic radiation disturbance problems. As another example, if the electromagnetic radiation standard exceeding frequency point is a low-frequency envelope, determining whether an external power line exists in the electronic device; if the external power line exists, adding a magnetic ring to the external power line to determine whether the electromagnetic radiation disturbance is reduced; and if the electromagnetic radiation disturbance is reduced, performing the electromagnetic radiation disturbance test again after adding the filter design at the power supply port, performing the filter design again after the test fails, and continuing performing the electromagnetic radiation disturbance test on the electronic equipment until the electronic equipment passes the electromagnetic radiation disturbance test. The embodiment of the application integrates a method for adding the magnetic ring, designs a set of electromagnetic radiation disturbance positioning and rectifying method, and provides a flow-based solution thought of different electromagnetic radiation disturbance problems. Wherein, the low-frequency power envelope (i.e. low-frequency envelope) refers to an envelope waveform with a frequency lower than 230Mhz in an electromagnetic radiation disturbance test of the electronic equipment, as shown by a point 1 in fig. 2; the high-frequency single point refers to a single-point waveform with a frequency exceeding 230Mhz in an electromagnetic radiation disturbance test of the electronic equipment, as shown by a point 2 in fig. 2.

In an exemplary embodiment, if the electronic device does not have an external power line, or the electromagnetic radiation disturbance is not reduced; and performing an electromagnetic radiation disturbance test on the shielding structure of the electronic equipment, performing a shielding design again after the test fails, and continuing to perform the electromagnetic radiation disturbance test on the electronic equipment until the electronic equipment passes the electromagnetic radiation disturbance test.

According to the above description, in an embodiment, as shown in fig. 3, a flow sequence of electromagnetic radiation disturbance positioning and rectification is enumerated, specifically:

step S101: and (5) positioning and correcting. And performing an electromagnetic radiation disturbance test on the electronic equipment according to the electromagnetic compatibility radiation disturbance test standard, and if the electromagnetic radiation disturbance test fails, entering the step S102.

Step S102: and (4) visually analyzing the frequency. Through the analysis of the frequencies of the frequency points with radiation disturbance exceeding the standard, whether a certain frequency doubling relationship exists between the frequency points with the exceeding the standard is judged, and then the frequency points with the exceeding the standard are considered to be regular points, if the frequencies of the frequency points with the exceeding the standard are 375MHz, 625MHz and 750MHz which are respectively 3 frequency doubling, 5 frequency doubling and 6 frequency doubling of 125MHz of a gigabit network clock, the frequency points with the exceeding the standard corresponding to 375MHz, 625MHz and 750MHz are considered to be regular points. If the frequency points are regular, the emission source is judged according to the fundamental frequency of each signal of the mainboard, the radiation disturbance test is carried out after the emission source is subjected to the filter design, if the test fails, the filter design is carried out again until the radiation disturbance test is passed, and the rectification is completed. If the frequency is not regular, the process proceeds to step S103.

Step S103: and (4) positioning and rectifying problems of the signal cable. If the frequency point is irregular, whether the electronic equipment has an external signal cable or not needs to be checked; if the electronic equipment is provided with an external signal cable, the signal cable is pulled out, and if the test is passed after the signal cable is pulled out, the electromagnetic disturbance performance of the cable is analyzed in terms of whether the cable is shielded or not, whether the shielding is grounded or not, whether the differential signal wire is twisted or not and the like, for example, the cable is provided with a shielding layer with good grounding, the differential signal cable is twisted, and the twisted-pair density is higher, so that the electromagnetic disturbance performance of the cable is considered to be better. And if the electromagnetic disturbance performance of the cable is not good, performing measures such as cable shielding, cable shielding layer grounding, differential signal wire twinning and the like, and then performing a radiation disturbance test, and if the test fails, performing filter design again until the radiation disturbance test passes, and finishing rectification. And if the electromagnetic disturbance performance of the cable is good, a radiation disturbance test is carried out after a filter design is added at the port of the cable, and if the test fails, the filter design is carried out again until the radiation disturbance test passes, so that the rectification is completed. If the electronic device has no external signal cable or the test fails after the external signal cable is unplugged, the method goes to step S104.

Step S104: and (4) positioning and rectifying the internal disorder problem. If the electronic equipment has no external signal cable or the test fails after the external signal cable is pulled out, the frequency points exceeding the standard need to be analyzed to see whether the frequency points exceeding the standard are low-frequency envelopes or high-frequency single points. If the single-point radio frequency spectrum is a high-frequency single-point radio frequency spectrum, the single-point radio frequency spectrum is proved to be the reason of the single board of the electronic equipment, a frequency spectrograph is needed to be matched with a near-field probe to carry out near-field measurement positioning, the radiation disturbance energy of the single board is higher, a radiation disturbance test is carried out after a filter design is added, if the test fails, the filter design is carried out again until the radiation disturbance test passes, and the rectification is completed. If the superscalar frequency point is the low frequency envelope, the process proceeds to step S105.

Step S105: and (5) correcting and correcting the problem location of the power cable. If the frequency point exceeds the standard is low-frequency envelope, whether the electronic equipment has an external power line needs to be judged, if the external power line exists, a magnetic ring is added on a power supply to see whether the electromagnetic disturbance is reduced, if the electromagnetic disturbance is reduced, the disturbance is proved to be brought out from a power supply port, a radiation disturbance test is carried out after the power supply port is provided with a filter design, if the test is failed, the filter design is carried out again until the radiation disturbance test is passed, and the rectification is completed. And if the electronic equipment has no external power line or the electromagnetic disturbance of the power line plus magnetic ring is not reduced, the step S106 is entered.

S106: and (4) positioning and rectifying the structural problem of the case. If the electronic equipment has no external power line or the electromagnetic disturbance of the power line plus magnetic ring is not reduced, the radiation disturbance test is carried out after the chassis is shielded, and if the test fails, the shielding design is carried out again until the radiation disturbance test passes, and the rectification and the improvement are completed.

The embodiment of the application divides the positioning rectification method of the irregular harassment frequency points into two types of signal cables and no signal cables through the inspection of the appearance. By analyzing the frequency points, the disturbance of an irregular and signal-free cable is divided into a high-frequency single point and a low-frequency power envelope. Through the analysis of the cable, the disturbance of the irregular and signal cable is divided into the disturbance of the cable reason and the disturbance of the non-cable reason. Whether power envelope exists or not is judged through analyzing frequency points, and the power envelope rectifying and modifying method is divided into two types of power lines and non-power lines. The power line interference rectifying and reforming thought is divided into two categories of power supply increasing filtering and case shielding by judging whether the radiation disturbance of the power line sleeve magnetic ring is reduced or not.

In conclusion, the method performs the electromagnetic radiation disturbance test on the target object; if the target object does not pass the electromagnetic radiation disturbance test, testing the electromagnetic radiation disturbance test parameters of the target object according to a preset test sequence, and making an adjustment strategy according to a test result; and adjusting the target object according to the adjustment countermeasures, and performing the electromagnetic radiation disturbance test on the target object again after the adjustment until the target object passes the electromagnetic radiation disturbance test.

In addition, the invention abandons the high-cost rectification and modification strategies such as sleeving a magnetic ring on a cable, completely shielding the whole machine and the like, provides the rectification and modification strategies which are convenient to lead in mass production and have lower cost, and better improves the electromagnetic compatibility of the electronic equipment. The method breaks through the disorder of the existing radiation disturbance problem positioning rectification mode, positions the source of the radiation disturbance problem through the analysis of disturbance waveforms, equipment structures, equipment cables and near-field measurement data, applies design schemes such as single-board filtering, structural shielding and cable grounding to the radiation disturbance suppression, provides a whole set of electromagnetic radiation disturbance problem positioning and rectification method, effectively improves the positioning accuracy and rectification efficiency, and reduces the authentication and test cost.

Specifically, if the frequency point is irregular, whether the electronic device has an external signal cable needs to be checked; if the electronic equipment is provided with an external signal cable, the signal cable is pulled out, and if the test is passed after the signal cable is pulled out, the electromagnetic disturbance performance of the cable is analyzed in terms of whether the cable is shielded or not, whether the shielding is grounded or not, whether the differential signal wire is twisted or not and the like, for example, the cable is provided with a shielding layer with good grounding, the differential signal cable is twisted, and the twisted-pair density is higher, so that the electromagnetic disturbance performance of the cable is considered to be better. And if the electromagnetic disturbance performance of the cable is not good, performing measures such as cable shielding, cable shielding layer grounding, differential signal wire twinning and the like, and then performing a radiation disturbance test, and if the test fails, performing filter design again until the radiation disturbance test passes, and finishing rectification. And if the electromagnetic disturbance performance of the cable is good, a radiation disturbance test is carried out after a filter design is added at the port of the cable, and if the test fails, the filter design is carried out again until the radiation disturbance test passes, so that the rectification is completed. If the electronic equipment has no external signal cable or the test fails after the external signal cable is pulled out, the electronic equipment enters an electromagnetic radiation standard exceeding frequency point unit D30.

The electromagnetic radiation frequency point exceeding unit D30 is used for analyzing electromagnetic radiation frequency points exceeding the standard, dividing the electromagnetic radiation frequency points exceeding the standard of the target object into low-frequency including and high-frequency single points, and making corresponding correction strategies. Specifically, if the electronic device has no external signal cable or the test fails after the external signal cable is unplugged, the frequency points exceeding the standard need to be analyzed to see whether the frequency points exceeding the standard are low-frequency envelopes or high-frequency single points. If the single-point radio frequency spectrum is a high-frequency single-point radio frequency spectrum, the single-point radio frequency spectrum is proved to be the reason of the single board of the electronic equipment, a frequency spectrograph is needed to be matched with a near-field probe to carry out near-field measurement positioning, the radiation disturbance energy of the single board is higher, a radiation disturbance test is carried out after a filter design is added, if the test fails, the filter design is carried out again until the radiation disturbance test passes, and the rectification is completed. If the superscalar frequency point is the low frequency envelope, the power line unit D40 is entered.

The power line unit D40 is used to analyze the power line, divide the target object into a target object with a power line and a target object without a power line, and make a corresponding correction measure. Specifically, if the frequency point exceeding the standard is low-frequency envelope, whether an external power line exists in the electronic equipment needs to be judged, if the external power line exists, a magnetic ring is added on a power supply to see whether electromagnetic disturbance is reduced, if the electromagnetic disturbance is reduced, the disturbance is proved to be brought out from a power supply port, a radiation disturbance test is carried out after the power supply port is subjected to a filtering design, and if the test fails, the filtering design is carried out again until the radiation disturbance test passes, and the rectification is completed. If the electronic equipment has no external power line or the electromagnetic disturbance of the power line plus magnetic ring is not reduced, the electronic equipment enters the shielding structure unit D50.

The shielding structure unit D50 is used to analyze the shielding structure and make a corresponding correction strategy according to the shielding structure. Specifically, if the electronic device has no external power line or the electromagnetic disturbance of the power line plus magnetic ring is not reduced, the radiation disturbance test needs to be carried out after the chassis is shielded, and if the test fails, the shielding design is carried out again until the radiation disturbance test passes, so that the rectification and the improvement are completed.
