As can be seen from the above, the electrical performance test system of the filter is mainly for suppressing noise of different frequencies, and therefore, the current monitoring module 1 includes a current input unit 11 and a current output unit 12;
after the tester connects the filter to the filter electrical property test system, the current input unit 11 transmits current to the filter, the current in the filter flows out through the current output unit 12, in the process, the current change conditions of the current input unit 11 and the current output unit 12 are collected by the current monitoring module 1, the current input unit 11 and the current output unit 12 serve as current input and output interfaces for testing the electrical property of the filter, and current frequency change monitoring devices are arranged in the current input unit 11 and the current output unit 12, so that the current frequency of the filter is monitored in real time, and the electrical property change condition of the filter is tested according to the change conditions of the current frequency in the later period.

；
；
；
Wherein A represents a filtered current frequency set of the filter stored in the electrical property information storage module 5 under the normal working condition; b represents a set of filtered current frequencies in detection of the filter transmitted by the image analysis unit current monitoring module 1; A comparison function representing the similarity of A and B; when the result of/> is 0, it indicates that the database of the electrical property information storage module 5 does not have the filtered current frequency similar to that detected by the current monitoring module 1; when/> is 1, it means that there is a similar filtered current frequency in the database of the electrical property information storage module 5 as the current monitoring module 1 detects.
In the process of using the filter, the use scene of the filter is gradually increased, the monitoring data published on the network is also gradually increased, and the possible working scene of the filter is also gradually increased, so that the change condition of the current frequency of the filter in various working environments is increased, and new information needs to be added in the electrical property information storage module 5, therefore, the big data information acquisition module 3 comprises a network information monitoring unit 31 and a feedback input unit 32;

The feedback input unit 32 collects feedback information of a user and transmits the collected information to the electrical property information storage module 5, in the process of putting the filter into use, the electrical property change information of the filter is more complex than that of detection in an actual working environment, so that the electrical property change information of the filter is more abundant, the current frequency change condition of the user in the process of putting the filter into use is uploaded through the feedback input unit 32 and then is transmitted to the electrical property information storage module 5, if the filtering effect of the filter cannot reach the expected value under a certain current frequency, the filter is likely to be encountered in the later stage due to the actual use scene, the filter is required to be tested under the working environment of the current frequency when the filter in the later stage leaves the factory, and the optimization direction of the filter with the specification can be assisted.
In addition, after the filter passes the normal electrical performance test, the current monitoring module 1 tests the filter according to the test collected by the network information monitoring unit 31 and the feedback input unit 32 and the user feedback information, if the filter which participates in the test in the later stage also has a fault condition, the design of the filter is problematic, optimization is needed, the working environment is set as a normal detection environment in the later stage, the accuracy of the electrical performance test of the filter is improved, meanwhile, the electrical performance information storage module 5 can randomly generate a current frequency variation trend (including the switching between the current frequency variation amplitude under the extreme condition and the normal current frequency variation amplitude), the current monitoring module 1 tests according to the randomly generated variation trend, the electrical performance condition of the filter can be further enriched, when the filter with other specifications is designed in the later stage, the information in the electrical performance information storage module 5 can be used as a reference, and if the current frequency variation randomly generated by the electrical performance information storage module 5 and the current frequency variation trend of the fault occurring when the filter actually works coincide, the electrical performance information stored in the electrical performance information storage module 5 is directly adopted.
