Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0019] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0020] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0021] See also Figure 1 , Figure 1 A schematic diagram of a process for suppressing shielding interference of a high-voltage connector provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the high-voltage connector shielding interference suppression method provided in the embodiment of the present application includes steps S1 to S5.

[0022] Step S1, obtain the current operating status of the power demand end connected to the high-voltage connector, and obtain the initial interference information and initial interference suppression information corresponding to the operating status in the database; wherein the initial interference information includes at least one initial interference signal, the initial interference suppression information includes at least one initial interference suppression signal, and the high-voltage connector is provided with a shielding layer.

[0023] Specifically, the current operating state of the power demand end is obtained, and the operating state is analyzed to obtain the operating condition combination corresponding to the operating state, and the database is searched based on the operating condition combination to obtain the initial interference information and the initial interference suppression information. It can be understood that one initial interference signal corresponds to one initial interference suppression signal.

[0024] Step S2: obtaining current interference information of the high-voltage connector through a preset interference information detection device, and determining whether the current interference information is consistent with the initial interference information.

[0025] Specifically, the interference information detection device is a spectrum analyzer or an oscilloscope, and the interference information detection device is arranged on the high-voltage connector. The interference information detection device receives signals around the high-voltage connector and performs spectrum and time domain analysis on the received signals to obtain current interference information of the high-voltage connector, compares and analyzes the current interference information with the initial interference information, and determines whether the current interference information is consistent with the initial interference information based on the result of the comparative analysis.

[0026] Step S3: If they are inconsistent, performing a difference analysis on the current interference information and the initial interference information to obtain interference difference information; the interference difference information includes at least one interference difference signal.

[0027] Specifically, a difference analysis is performed on the current interference information and the initial interference information, and interference information that does not exist in the initial interference information is extracted from the current interference information as the interference difference information. The initial interference information is interference information emitted by a device in the power supply end or the power demand end connected to the high-voltage connector, and the interference difference information is interference information emitted by an external device that is not related to the high-voltage connector.

[0028] It should be noted that if the current interference information is consistent with the initial interference information, the current interference information is suppressed based on each of the initial interference suppression signals. Specifically, for each of the initial interference suppression signals, the initial interference suppression signal is radiated outward through the directional radiation antenna corresponding to the initial interference suppression signal. The directional radiation antenna is arranged near the interference source corresponding to the initial interference suppression signal. The interference source here refers to the device in the power supply end or the power demand end connected to the high-voltage connector.

[0029] Step S4: for each of the interference difference signals, generate a target interference suppression signal corresponding to the interference difference signal.

[0030] Specifically, the interference difference signal is processed inversely to obtain a target interference suppression signal having an amplitude equal to that of the interference difference signal and an opposite phase.

[0031] Step S5: Suppress the current interference information based on each of the initial interference suppression signals and each of the target interference suppression signals.

[0032] Specifically, for each of the initial interference suppression signals, the initial interference suppression signal is radiated outwardly through a directional radiation antenna corresponding to the initial interference suppression signal, and the directional radiation antenna is arranged near an interference source corresponding to the initial interference suppression signal; For each of the target interference suppression signals, the position of the positioning radiating antenna on the high-voltage connector is adjusted so that the propagation path of the signal radiated by the positioning radiating antenna is opposite to the propagation path of the interference difference signal corresponding to the target interference suppression signal, and after adjusting the position of the positioning radiating antenna, the target interference suppression signal is radiated outward through the positioning radiating antenna.

[0033] It can be understood that the initial interference suppression signal in step S5 is used to suppress interference information emitted by devices in the power supply end or power demand end connected to the high-voltage connector, and the target interference suppression signal is used to suppress interference information emitted by external devices unrelated to the high-voltage connector.

[0034] The method provided in this embodiment, on the one hand, realizes dynamic identification and classification of interference information, and can distinguish interference signals of devices related to the high-voltage connector and interference signals emitted by external devices. Compared with the traditional static shielding method that simply relies on the shielding layer, the method can adopt corresponding suppression strategies for different interference signals to improve the accuracy and efficiency of interference suppression. On the other hand, through step S5, a multi-level and multi-signal source collaborative suppression method is realized, which effectively solves the problem in the prior art that the shielding layer cannot fully cover and cope with various interference signals, and significantly improves the anti-interference ability of the high-voltage connector.

[0035] In some embodiments, before obtaining the operating status of the power demand end connected to the high-voltage connector, the method further includes the following steps: Construct a virtual power supply system of the power supply system corresponding to the high-voltage connector; the power supply system includes a power supply end, the high-voltage connector, and the power demand end, and the virtual power supply system includes a virtual power supply end corresponding to the power supply end, a virtual high-voltage connector corresponding to the high-voltage connector, and a virtual power demand end corresponding to the power demand end; Acquire the working condition information of the power demand end; the working condition information includes various working conditions of the power demand end; Performing a combination operation on each of the working conditions to obtain a plurality of working condition combinations; wherein one working condition combination corresponds to one operating state; specifically, performing a combination operation on each of the working conditions refers to calculating all possible situations of extracting any number of working conditions from each of the working conditions, for example, the working condition information includes working condition 1, working condition 2 and working condition 3, then the working condition combination includes seven working condition combinations: {working condition 1}, {working condition 2}, {working condition 3}, {working condition 1, working condition 2}, {working condition 1, working condition 3}, {working condition 2, working condition 3}, {working condition 1, working condition 2, working condition 3}; For each of the operating states, the virtual power supply system is controlled to operate in the operating state, and during the operation of the virtual power supply system, initial interference information corresponding to the operating state is obtained through a preset virtual interference information detection device; the initial interference information includes at least one initial interference signal; For each of the initial interference signals, an initial interference suppression signal corresponding to the initial interference signal is generated; each of the initial interference suppression signals constitutes initial interference suppression information corresponding to the operating state; specifically, the initial interference signal is reversely processed to obtain an initial interference suppression signal having an amplitude equal to that of the initial interference signal and an opposite phase; The initial interference information is bound to the initial interference suppression information to obtain a binding result, and the binding result is encrypted based on the running state, and the encrypted binding result is stored in the database.

[0036] The method provided in this embodiment, by comprehensively constructing the operating status, realizes comprehensive analysis and dynamic suppression of interference information of the power supply system under all possible operating states, helps to improve the anti-interference capability of the power supply system, and provides an effective solution for interference suppression of high-voltage connectors.

[0038] In this embodiment, after determining whether the number of operating conditions in the operating condition combination corresponding to the running state is 1, the method further includes the following steps: If not, the numbers of the various operating conditions in the operating condition combination corresponding to the operating state are arranged in order from small to large to obtain a number sequence; Determining that the number of operating conditions in the operating condition combination is a third value; Obtaining a preset coding algorithm matrix; each position of the coding algorithm matrix is ​​provided with a coding algorithm; Determine that the encoding algorithm in the column corresponding to the third value is a third target encoding algorithm; For each of the third target coding algorithms, encoding the numbering sequence based on the third target coding algorithm to obtain a third coding sequence; Arrange the third coding sequences in order from top to bottom in a preset blank table based on the positions of the third target coding algorithms corresponding to the third coding sequences in the coding algorithm matrix to obtain an initial table; Determine whether there are blank cells in the initial table; If it exists, insert the preset element into the blank cell to obtain the target table; A first ray is drawn toward the target table with the endpoint at the lower left corner of the target table as the ray endpoint; the value corresponding to the angle between the first ray and the bottom of the target table is consistent with the first value; A second ray is drawn toward the target table with the endpoint at the lower left corner of the target table as the ray endpoint; the value corresponding to the angle between the second ray and the bottom of the target table is consistent with the third value; Determine that a character in a cell passed by the first ray and the second ray in the target table is a third target character; Based on the position of each of the third target characters in the target table, the third target characters are arranged in sequence to obtain an encryption sequence, and the binding result is encrypted based on the encryption sequence.

[0039] The method provided in this embodiment can effectively prevent the binding result from being tampered with, thereby ensuring the effectiveness of interference suppression of the high-voltage connector.
