Description

Technical Field

[0001] The present invention belongs to the technical field of box-type transformer safety detection, and in particular is a new energy box-type transformer safety monitoring and control system. Background Art

[0002] The patent with publication number CN211015510U discloses a high-security permission box-type transformer measurement and control device, including a box-type transformer measurement and control device body, a fingerprint recognition sensor, a fingerprint recognition circuit, an authority processing unit and a server. The fingerprint recognition sensor is arranged on the box-type transformer measurement and control device body for collecting fingerprint images. The fingerprint recognition circuit is connected to the fingerprint recognition sensor for receiving and obtaining fingerprint recognition information based on the fingerprint image. The authority processing unit is connected to the fingerprint recognition circuit for comparing the collected fingerprint recognition information with the user fingerprint information stored in the server, and deciding whether to grant permission to use the box-type transformer measurement and control device body based on the fingerprint comparison result. The server is connected to the authority processing unit, and the server stores user fingerprint information, which effectively avoids the misoperation of the box-type transformer measurement and control device by unauthorized personnel due to password leakage, avoids intentional or unintentional human damage, and greatly improves the safety of the operation site.

[0003] For box-type substations, security reports indicate that attacks can infiltrate the box-type substation monitoring system through phishing emails and vulnerability exploits, stealing grid operation data or disrupting equipment stability. Internal threats and privilege abuse can also lead to tampering with box-type substation data. Tampering with detected data can trigger incorrect protection mechanisms, or even prevent the correct ones from being triggered. Currently, there is a lack of solutions, so a technology is proposed to address this issue. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art;

[0005] To this end, the present invention proposes a new energy box-type transformer safety monitoring and control system, comprising:

[0006] The initial state analysis unit is used to screen all threshold data detected in the box-type transformer. The alarm times (indicating the number of abnormal threshold data) and the abnormal times (indicating the number of tampered threshold data) are weighted and then calculated to obtain the comprehensive times. The high-risk targets and corresponding target values are screened based on the comprehensive times.

[0007] The peripheral end is used to convert the high-risk target into a serial number representing the high-risk target, convert it into an RGB value according to the serial number, and the formed color representation is assigned to the picture. Then, the target value is divided into the number before the dot and the number after the dot according to the existence of the decimal point. Then, the number before the dot and the number after the dot are converted into several groups of fused numbers, and the fused numbers are converted into RGB values to form a color representation and assigned to the picture. The colors between the serial number and the target value are separated by a separator, and the number before the dot and the number after the dot are separated by separator two, so that the high-risk target and the target value are integrated into the picture.

[0008] Furthermore, the method of obtaining high-risk labels is:

[0009] Obtain the comprehensive scores of all threshold targets, sort the threshold targets according to the comprehensive scores, mark the top 30% as high-risk targets, then mark the bottom 30% as low-risk targets, and mark the rest as regular targets.

[0010] Furthermore, the peripheral device end is periodically connected to the control unit, and when the connection is not established, the peripheral device end cannot be connected to the initial state analysis unit through the control unit.

[0011] Furthermore, the peripheral end includes an electronic switch unit, which is used to connect the processor and the control unit, and the control unit is used to connect the processor and the initial state analysis unit.

[0012] Furthermore, the peripheral end also includes a processor. When the processor receives high-risk targets and target values, it will give all high-risk targets a sequence number. The sequence number is the high-risk targets sorted from large to small according to their corresponding comprehensive scores, and is determined by the sorting number.

[0013] Furthermore, each serial number is automatically filled with a three-digit number, and then the numbers are assigned values called RGB in sequence to generate corresponding colors, which are filled in the left side of the separator of the empty picture. The separator is preset by the administrator and is used to distinguish the color representation of the serial number and the label value.

[0014] Furthermore, the target value is obtained, and the value before the decimal point is marked as the value before the decimal point, and the rest is marked as the value after the decimal point;

[0015] By adding the value 0 to the front of the value before and after the point, the number of digits in the value before and after the point is supplemented to the minimum multiple of three;

[0016] Then the values before and after the dot are divided into several fusion numbers in groups of three. If any of the fusion numbers exceeds 255, a title signal is generated. Otherwise, each fusion number is assigned an RGB value to form a corresponding color representation. The order is placed after the separator of the image. There is a separator between the color representations of the values before and after the dot for distinction.

[0017] Thus, a picture of all high-risk targets and their target values is obtained and marked as a data picture group;

[0018] Furthermore, if only the title signal is generated, the separator in the image will be cancelled, and the labeled value will be used as the name of the image after cancellation; all colors in the image are automatically filled with the colors generated by the RGB values corresponding to the sequence numbers.

[0019] Furthermore, if the number of sequence numbers exceeds 255, if no title signal is generated at this time, only the color generated by the target value will be placed in the picture. If the target value cannot generate separator 2, separator 2 will be placed in the last column of the color generated by the target value to form a picture; then the name of the picture is marked as the sequence number.

[0020] Furthermore, if the number of sequence numbers exceeds 255 and a title signal is generated at the same time, the sequence number and the value will be used as the image name, and the two will be separated by a separator. Then, the content generated in the image will only contain the separator and separator 2, and the rest will be filled with white to generate the image.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present application converts a high-risk target into a serial number representing the high-risk target through an external device, converts it into an RGB value according to the serial number, and assigns the formed color representation to the picture. Then, the target value is divided into the number before the dot and the number after the dot according to the existence of the decimal point, and then the number before the dot and the number after the dot are converted into several groups of fused numbers. According to the fused number, they are converted into RGB values to form a color representation and assigned to the picture. The colors between the serial number and the target value are separated by a separator, and the number before the dot and the number after the dot are separated by separator two, thereby integrating the high-risk target and the target value into the picture; thereby achieving another form of backup for some critical or frequently attacked data, and periodic detection to determine whether the data has been tampered with, thereby avoiding security risks caused by data tampering.

[0025] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 , this application provides a new energy box transformer safety monitoring and control system, including;

[0027] The data acquisition unit is used to synchronize various threshold data detected in the corresponding box-type transformer. The threshold data includes the threshold label and its corresponding label value. The threshold label refers to the corresponding detected object, generally including current, temperature, fault arc and other data; the corresponding label value is the threshold for alarming or triggering early warning of the detection target. When the real-time data exceeds these ranges or falls below these ranges, an abnormal alarm will be issued;

[0028] All abnormal records are obtained, including alarm data and fault data. Alarm data and fault data are corresponding data names, belonging to one or more of the threshold labels. Alarm data is generated in the following situations: when the intelligent unit in the box-type transformer detects abnormal data, such as real-time monitoring of current and voltage fluctuations, identification of overload or short circuit anomalies, etc., and generates abnormal alarms or disconnection actions based on certain parameters. Fault data is detected when certain data is tampered with or tampered successfully but not detected.

[0029] The data acquisition unit is used to transmit threshold data, alarm data and abnormal data to the initial state analysis unit. The initial state analysis unit is used to analyze the importance of the data. The specific analysis method is as follows:

[0030] Get the threshold mark in the threshold data, then get the number of times it appears in the alarm data, mark it as an alarm, get the number of times all threshold marks appear in the abnormal data, mark it as an abnormal;

[0031] Obtain the number of alarms and exceptions for each threshold target, and calculate the comprehensive number according to the formula. The specific calculation formula is:

[0032] Comprehensive times = 0.59 × alarm times + 0.41 × abnormal times;

[0033] In the formula, 0.59 and 0.41 are preset weights, which are used to reflect the different importance of alarm times and abnormal times;

[0034] Then, the comprehensive score of each threshold target is obtained, and the threshold targets are sorted according to the comprehensive score. The top 30% are marked as high-risk targets, and the bottom 30% are marked as low-risk targets. The rest are marked as regular targets.

[0035] Get all high-risk targets and their corresponding target values;

[0036] The initial state analysis unit transmits high-risk targets and their target values to the peripheral end for backup through the comparison unit, and periodically compares the high-risk targets and their corresponding target values with the corresponding detection targets and target values received by the initial state analysis unit through the comparison unit to find the modified parameters. The peripheral end and the comparison unit are periodically connected. When the connection is not established, the peripheral end cannot connect to the initial state analysis unit through the comparison unit. The period here is set by the administrator, and the analyzed high-risk targets and target values are not stored in the peripheral end for backup until the period reaches the point where the peripheral end and the comparison unit are connected.

[0037] Of course, as the second embodiment of the present application, this embodiment is implemented on the basis of the first embodiment, and differs from the first embodiment in that the peripheral end in this embodiment specifically includes an electronic switch unit, a processor, a first storage unit, and a second storage unit;

[0038] The electronic switch unit here uses an electronic switch, such as a solid-state relay, contactor, or some mechanical contact device, to achieve periodic connection / disconnection with the box-type transformer through control signals. It can support triggering conduction based on preset time, voltage / current thresholds, and external commands. In other words, the electronic switch unit here is used to connect the processor and the control unit.

[0039] When the electronic switch unit on the peripheral side receives a high-risk target and its target value, it will transmit the high-risk target and the target value to the processor. When the processor receives the high-risk target and the target value, it will perform a copy process. The specific copy process is as follows:

[0040] First, obtain all high-risk targets and assign a sequence number to each of them. The sequence of high-risk targets can be sorted from largest to smallest according to the comprehensive score, and the sequence number is used to determine the order.

[0041] Then each sequence number is automatically filled to form a three-digit number, for example, 1 is automatically changed to 001, and 15 is automatically changed to 015;

[0042] Get the serial number of each high-risk target;

[0043] Choose any high-risk target and its target value;

[0044] First, the sequence number of the high-risk target is obtained. Generally, the sequence number does not exceed 255. Therefore, an empty image is first generated here, and then the empty image is divided into two half areas using a typical separator. The separator can be identified to distinguish the sequence number from the target value.

[0045] On the left side of the separator, use the three-digit number generated by the sequence number to assign the number to the corresponding RGB value to generate a color and fill the left side of the separator;

[0046] Then get the target value, get the value before the decimal point, mark it as the number before the decimal point, and mark the value after the decimal point as the number after the decimal point;

[0047] Get the number of numbers before and after the dot. If the number is not an integer multiple of three, automatically add the minimum 0 value to the number before and after the dot, so that the number of numbers before and after the dot is an integer multiple of three. For example, if the number before the dot is 2543, the number before the dot will be automatically optimized to 002543 instead of 000002543.

[0048] Then, the numbers before the dot are divided into several groups of fusion numbers according to three. If there is a fusion number exceeding 255, a title signal is generated. Similarly, if there is a fusion number exceeding 255 in the numbers after the dot, a title signal is also generated.

[0049] When no title signal is generated, the first fusion number of the number before the dot is obtained, and then the value is assigned to the RGB value. After generating the corresponding color, it is filled in the first column to the right of the separator. Then the second column is filled with the color generated by the second fusion number until the number before the dot is filled. Then the second separator is introduced. The second separator is different from the separator and is used to distinguish the number before the dot from the number after the dot.

[0050] Similarly, fill the columns after the second separator with the groups of fused numbers formed by the numbers after the dot. Here, the area of the column occupied by each group of fused numbers before and after the dot is obtained by equally dividing the space to the right of the corresponding separator.

[0051] The image names formed by the above process are randomly generated and no numbers are used.

[0052] If only the title signal is detected, the separator in the image will be cancelled, and the target value will be used as the name of the image; all colors in the image will be automatically filled with the color generated by the RGB value corresponding to the sequence number;

[0053] Obtain a picture of all high-risk targets and their target values, and mark it as a data picture group;

[0054] After generating the data picture groups, the processor stores all the data picture groups into the first storage unit;

[0055] When the electronic switch unit is connected to the control unit according to the set cycle, the data image group will be re-translated into the corresponding high-risk targets and target values in the opposite way of the copying process, and then automatically compared with the detection targets and target values stored in the box transformer with the help of the control unit to see whether the threshold target value has been tampered with. If tampered with, it will be automatically restored and a warning will be issued.

[0056] As the third embodiment of the present application, this embodiment is implemented on the basis of the second embodiment, except that the sequence number is generated in a different manner in this embodiment;

[0057] Alternatively, a three-digit serial number may be randomly assigned, where the first digit is less than or equal to 2, and the remaining two digits are less than or equal to 5;

[0058] After the assignment is completed, a sequence mapping table is formed, and the comparison sequence table includes the sequence number and the corresponding high-risk target.

[0059] Of course, if the number of sequence numbers here exceeds 255, a different method is used. If no title signal is generated, only the color generated by the target value is placed in the picture. If the target value cannot generate the second separator, the second separator is placed in the last column of the color generated by the target value to form the picture; then the name of the picture is marked as the sequence number;

[0060] If the number of sequence numbers exceeds 255 and a title signal is generated, both the sequence number and the label value will be used as the image name, separated by a separator. Then, the content generated in the image will only contain the separator and separator 2, and the rest will be filled in white to generate the image.

[0061] Some of the data in the above formula are calculated by removing the dimensions and taking their numerical values. The formula is a formula that is closest to the actual situation obtained by software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained through simulation of a large amount of data.

[0062] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
