Description

Technical Field

[0001] The present application relates to the field of security management technology, and in particular to a global security management method and management system based on a five-defense system. Background Art

[0002] The five-protection system (preventing accidental opening and closing of circuit breakers; preventing opening and closing of disconnectors under load; preventing hanging (closing) of grounding wires (grounding switches) under power; preventing closing of circuit breakers (disconnectors) with grounding wires (grounding switches) under power; preventing accidental entry into live intervals) is the main equipment for preventing misoperation in substations. It is an important equipment to ensure the safe operation of substations and prevent human misoperation. Any normal switching operation must undergo simulation rehearsal and logical judgment of the five-protection system. The intervention of the five-protection system can effectively reduce the occurrence of power grid accidents.

[0003] The working principle of the five-protection system is to simulate the rehearsal operation on the anti-error host before the switching operation. The anti-error host performs interlocking logic judgment on each simulated operation based on the pre-stored anti-error interlocking logic library and the current equipment position status, and generates the actual operation program based on the correct simulation operation content and transmits it to the computer key. The operator opens the corresponding coded locks in turn according to the operation content displayed on the computer key to operate the equipment.

[0004] The five-defense system is needed for simulation during the construction process, but how to make the operation consistent with the simulation process to ensure safety during the construction process requires further research. Summary of the invention

[0027] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0028] This application discloses a global security management method based on a five-defense system. Figure 1 and Figure 2 In some examples, the global security management method based on the five-defense system disclosed in this application includes the following steps: S101, scanning the information tag on the grounding pile and the identification code on the grounding switch (grounding wire), scanning the information tag to obtain the unique lock code number and geographical location information of the grounding pile, and scanning the identification code to obtain the unique number of the grounding switch; S102, matching the unique lock code number of the grounding pile with the unique serial number of the grounding switch; S103, sending an unlocking request to the cloud, which performs a five-defense logic check on the unlocking request and then issues an unlocking confirmation code; S104, forwarding the unlocking confirmation code to the five-protection key, which is configured to be used to open an electronic switch belonging to the grounding switch (grounding wire); The unlocking application includes at least one grounding switch (grounding wire); When the unlocking application cannot pass the five-protection logic verification, rescan the information label on the grounding pile and the identification code on the grounding switch (grounding wire) or modify the grounding switch (grounding wire) included in the unlocking application.

[0029] The equipment for executing the technical solution in this application is collectively referred to as a terminal in the following description. The terminal can be a mobile phone, a tablet, a customized device, etc. The staff carries the terminal and the five-defense key to complete the global security management method based on the five-defense system disclosed in this application.

[0030] Specifically, in step S101, the terminal first scans the information tag on the grounding pile and the identification code on the grounding switch (grounding wire), scans the information tag on the grounding pile to obtain the unique lock code number of the grounding pile, and scans the identification code on the grounding switch (grounding wire) to obtain the unique number of the grounding switch.

[0031] After the scan is completed, execute step S102. In this step, it is necessary to match the unique lock code number of the grounding pile and the unique number of the grounding switch. This is because the grounding pile and the grounding switch (grounding wire) have unique connectivity, that is, the grounding switch (grounding wire) will be connected to a fixed grounding pile. The purpose of matching is to ensure the correspondence between the grounding pile and the grounding switch (grounding wire).

[0032] Matching can be done locally or in the cloud.

[0033] Because the grounding pile has a location feature and the grounding switch (grounding wire) has a connection feature, the construction position can be directly obtained by scanning the grounding pile. For the construction position, there are three ways: directly binding the construction position with the grounding pile, determining through the terminal, and manual input.

[0034] As for the grounding switch (grounding wire), during the subsequent use, maintenance and upgrading, the grounding switch (grounding wire) may be replaced, increased or reduced. Therefore, the grounding switch (grounding wire) generally does not have a position feature, but its position is determined according to the grounding pile connected to it.

[0035] In addition, the connection between the grounding pile and the grounding switch (grounding wire) may not be obvious and needs to be determined by matching the unique lock code number of the grounding pile with the unique number of the grounding switch.

[0036] In step S103, the terminal sends an unlocking application to the cloud, and the cloud performs a five-defense logic check on the unlocking application and then issues an unlocking confirmation code. The cloud here can be a five-defense system or other systems with five-defense functions.

[0037] The unlocking application can include one grounding switch (grounding wire) or multiple grounding switches (grounding wires). The specific number needs to be determined according to the actual work content. And when the unlocking application fails to pass the five-defense logic check, it is necessary to rescan the information label on the grounding pile and the identification code on the grounding switch (grounding wire) or modify the grounding switch (grounding wire) included in the unlocking application.

[0038] The purpose of rescanning is to determine the range. For example, if the input modification method is used, there is a possibility of input modification error but the five-protection logic check can be passed. At this time, the grounding switch (grounding wire) that should be closed is not closed, and the grounding switch (grounding wire) outside the range is closed.

[0039] Described from another perspective, rescanning is a fool-proof mode that enables staff to know how many grounding switches (grounding wires) have been scanned and where these grounding switches (grounding wires) are located through actual position movement and position determination.

[0040] After the five-protection logic check passes, the cloud sends an unlock confirmation code, and then executes step S104. In this step, after receiving the unlock confirmation code, the terminal forwards the unlock confirmation code to the five-protection key. The function of the five-protection key is to open the electronic switch belonging to the grounding switch (grounding wire). The electronic switch here can be an electronic lock, a chip lock, etc.

[0041] The advantage of an electronic switch is that it can only be opened with permission, avoiding operation by irrelevant personnel and misoperation by staff.

[0042] Overall, the global safety management method based on the five-defense system provided in this application ensures whether the grounding knife switch (grounding wire) can be closed by scanning and matching the grounding piles and grounding switches (grounding wires) within the construction scope and performing five-defense logic verification in the cloud. It also introduces a fool-proof design to enable staff to clearly identify the number and location of the grounding knife switches (grounding wires), thereby ensuring safety during the construction process.

[0043] In some examples, when using an unlock confirmation code to open an electronic switch belonging to a grounding switch (grounding wire), a cloud audit is required. The purpose of the cloud audit is to confirm the correspondence between the unlock confirmation code and the grounding switch (grounding wire).

[0044] There are two ways to implement cloud-based audit: scanning audit and location audit. Scanning audit means that after the five-protection key scans the electronic switch of the grounding switch (grounding wire), the code of the electronic switch of the grounding switch (grounding wire) needs to be sent to the cloud for audit. The electronic switch can be opened only after the audit is passed.

[0045] There are two ways to implement it: See also Figure 3 The first method is to use the five-protection key to scan twice. After the first scan, the code of the electronic switch of the grounding knife switch (grounding wire) is sent to the cloud for review. After the review is passed, the cloud sends an unlocking confirmation code. The second time, the unlocking confirmation code is used to open the electronic switch of the grounding knife switch (grounding wire).

[0046] The number of times the cloud sends unlock confirmation codes is the same as the number of electronic switches, that is, each electronic switch needs to be unlocked by the corresponding unlock confirmation code.

[0047] In some possible implementations, the unlocking confirmation code is generated based on the code of the electronic switch, and can even be discarded directly after being used once. In this case, the electronic switch and the cloud use the same generation method to generate the code of the electronic switch, that is, the code of the electronic switch is a dynamic code.

[0048] This method can also realize opening multiple electronic switches in sequence. The specific method is that the cloud will issue different unlocking confirmation codes according to different electronic switches. After each electronic switch is confirmed to be opened, the next unlocking confirmation code will be issued.

[0049] Alternatively, after the electronic switch of the grounding switch (grounding wire) is triggered, an unlocking request is sent to the cloud. After the cloud review is passed, the electronic switch of the grounding switch (grounding wire) is automatically opened.

[0050] The second type is location audit. Location audit is a more stringent audit method, which requires the location of the staff to be determined. Only when the staff's location is within the specified range can the five-protection key be used to unlock the door.

[0051] It should be noted that for electronic switches, it is difficult to realize the automation and intelligence of each electronic switch (communicating with the five-protection key and the cloud), and the cost of implementation is relatively high. A suitable and low-cost implementation method is that the electronic switch only has local communication function or local interaction function, and only communicates or interacts with the five-protection key.

[0052] In some possible implementations, when the unlocking confirmation code issued includes a sequence code, the cloud-based audit only uses position audit to ensure that the five-protection key can open multiple electronic switches in the set order.

[0053] It should be noted that the first method requires multiple communications with the cloud. Therefore, in actual use, when the communication situation is not good, there may be problems such as being unable to enter the construction site or having to wait for a long time. Therefore, the location review method is preferred in this application.

[0054] In some examples, scanning auditing can also be implemented as follows: After receiving the unlocking confirmation code, the five-protection key belonging to the grounding switch (grounding wire) sends the received unlocking confirmation code to the cloud. The cloud compares the received unlocking confirmation code with the issued unlocking confirmation code. When the received unlocking confirmation code and the issued unlocking confirmation code are consistent, the cloud sends an unlocking command to the five-protection key.

[0055] In some examples, the steps for a location audit are as follows: S201, determining the number of grounding switches (grounding wires) and the position coordinates of each grounding switch (grounding wire); S202, calculating the location coordinates of the terminal and generating a movement trajectory according to the location coordinates; S203, calculating the minimum straight-line distance between the position coordinates of each grounding switch (grounding wire) and the moving trajectory; S204: When each minimum straight-line distance is less than or equal to the set distance threshold, the location review result is sent to the cloud.

[0056] See also Figure 4 In step S201 to step S204, the coordinates of the grounding switch (grounding wire) and the moving trajectory of the terminal are compared. In this process, the minimum straight-line distance between the position coordinates of each grounding switch (grounding wire) and the moving trajectory is calculated. When each minimum straight-line distance is less than or equal to the set distance threshold, the location review result is sent to the cloud.

[0057] This method ensures that the terminal can be moved to each grounding switch (grounding wire) position in sequence. The reason for using the terminal here is that the five-protection key is difficult to complete position calculation and other related content, and the five-protection key has the authority to open the electronic switch and cannot modify the internal program at will.

[0058] When calculating the position coordinates of the terminal and generating the moving trajectory based on the position coordinates, the environmental signal is needed. The environmental signal is generated by the second terminal. The second terminal is located at a fixed position, where the coordinates are known quantities. The position coordinates of the first terminal are calculated based on the relative positions of the two terminals.

[0059] The specific steps are as follows: S301, receiving an environmental signal and separating a positioning signal wave emitted by an auxiliary positioning terminal from the environmental signal, the number of receiving positions is two, and the number of transmitting positions of the positioning signal wave is one; S302, determining the direction of the positioning signal wave; S303, calculating the position coordinates according to the transmission position of the positioning signal wave and the distance between the two receiving positions; S304, continuously acquiring position coordinates in a time series and generating a movement trajectory according to the position coordinates.

[0060] Here, the environmental signal is first received, and then the positioning signal wave emitted by the auxiliary positioning terminal is separated from the environmental signal. Since the frequency and amplitude of the positioning signal wave are known quantities, it can be easily separated from the environmental signal.

[0061] The transmitting position of the positioning signal wave is one, and the transmitting position here refers to the position of the auxiliary positioning terminal, and the position (coordinates) of the auxiliary positioning terminal is a known quantity.

[0062] The number of receiving positions is two, which means that there are two groups of antennas on the terminal. The location of each group of antennas is a receiving position. According to the difference in the positioning signal waves received at the two receiving positions, the relative position of the terminal and the auxiliary positioning terminal can be calculated.

[0063] After receiving the positioning signal wave, it is necessary to determine the direction of the positioning signal wave. Here, the antenna matrix is ​​needed. The antenna matrix uses an algorithm (such as the music algorithm) to calculate the direction of the signal. The intersection of the two directions is the transmission position of the positioning signal wave.

[0064] See also Figure 5 , and then calculate the position coordinates based on the transmission position of the positioning signal wave and the distance between the two receiving positions. Here, the transmission position of the positioning signal wave is a known quantity, and the distance between the two receiving positions ( Figure 5S) in is a known quantity. A reference line segment is established based on the two receiving positions. Then two direction lines can be drawn through the angle. The intersection of the two direction lines is the emission position of the positioning signal wave.

[0065] exist Figure 6 In the figure, the launch position is outside the terminal's moving range (dashed box).

[0066] Based on the above, we can get a triangle. The length of one short side of the triangle is known, the angle between the two long sides and the short side is known, and the intersection of the two long sides is known. According to trigonometric functions, the distance between the two long sides can be calculated.

[0067] At this time, the triangle can be rotated with the launch position as the center, and the rotation will get an arc. At least two arcs are required to determine the launch position. These two arcs have an intersection. At this time, two receiving positions need to be adjusted. The adjustment method is to rotate in a small range so that the inclination of the projection of the line connecting the two receiving positions on the same plane changes. When the inclination changes, the projections of the lines connecting the two receiving positions before and after the adjustment on the same plane are not parallel.

[0068] The spatial attitude of the line connecting the two receiving positions relative to the horizontal plane is determined by the gyroscope inside the terminal, because only by determining the spatial attitude of the line connecting the two receiving positions relative to the horizontal plane can the arc be obtained. As for the adjustment of the two receiving positions, it can be achieved by a micromotor. The two antennas are installed on the same circuit board, and the micromotor drives the circuit board to swing.

[0069] Based on the distance between the two long sides, the coordinates of the two receiving positions can be obtained. At this time, one of them can be selected as the position coordinate of the terminal, or the coordinates of the two receiving positions can be averaged and used as the position coordinate of the terminal.

[0070] With the location coordinates of the terminal, the movement trajectory can be generated.

[0071] In some examples, the method of separating the positioning signal wave emitted by the auxiliary positioning terminal from the environmental signal is: S401, generating a wavelet using relevant parameters of the positioning signal wave; S402, superimposing the wavelet on the environmental signal and moving it, and separating the positioning signal wave emitted by the auxiliary positioning terminal from the environmental signal according to the superimposition and movement result; There are multiple separated positioning signal waves, and each positioning signal wave has a starting time node and an end time node; The positioning signal wave interval at the transmitting position is generated. In the time series, there is a time interval between two adjacent positioning signal waves. The two receiving positions respectively separate the positioning signal waves sent by the auxiliary positioning terminal from the environmental signals to obtain two groups of positioning signal waves; The arrival time difference between two corresponding positioning signal waves in the two groups of positioning signal waves is calculated using the average of the difference between the starting time nodes of two corresponding positioning signal waves in the two groups of positioning signal waves.

[0072] Step S401 and step S402 use the wavelet decomposition method to separate the positioning signal wave emitted by the auxiliary positioning terminal from the environmental signal. First, the wavelet is generated using the relevant parameters of the positioning signal wave. The parameters here are frequency and amplitude. The frequency of the wavelet is the same as the frequency of the positioning signal wave. The maximum amplitude of the wavelet is 0.95-1.05 times that of the positioning signal wave. The attenuation rate of the amplitude is controlled at 0.95-0.99. The attenuation rate of the amplitude refers to the ratio of two adjacent peaks in the generated wavelet. The maximum peak is located in the middle position of the wavelet. In the direction away from the middle position (two), the amplitude of the wavelet tends to decrease, that is, the wavelet has the characteristics of high in the middle and low on both sides.

[0073] The advantage of wavelet is that it has both time domain characteristics and frequency domain characteristics. It can determine the time when the positioning signal wave is received. Through the time difference of receiving two positioning signal waves, the distance difference between the two long sides obtained in the above content can be corrected to obtain accurate position coordinates.

[0074] The correction method is to calculate the theoretical difference between the two long sides based on the time difference between the two positioning signal waves, and then compare the theoretical difference with the actual difference between the two long sides. If the error is within the allowable range, the position coordinates obtained at this time are used, otherwise the calculation is recalculated.

[0075] In some examples, the following is added: S501, placing two corresponding positioning signal waves in two groups of positioning signal waves into the same coordinate system; S502, cutting two corresponding positioning signal waves to retain the complete part of the positioning signal wave; S503, adjusting the relative positions of two corresponding positioning signal waves according to the distance between the corresponding wave crests or the corresponding wave troughs, so that the distances tend to be consistent; S504, counting the dispersion of the distance and determining the correct value of the distance according to the dispersion; S505: Use the correct value as the arrival time difference between two corresponding positioning signal waves.

[0076] See also Figure 7 and Figure 8 ( Figure 8The wave represented by the dotted line moves to the left), in steps S501 to S505, the arrival time difference of the two corresponding positioning signal waves is further determined by calculation, and the relative positions of the two corresponding positioning signal waves are adjusted according to the distance between the corresponding wave peaks or the corresponding wave troughs to make the distances tend to be consistent.

[0077] The way to make the distances consistent is to represent the distances as points, which are located in an area with an upper boundary and a lower boundary. When adjusting the relative positions, the distance between the upper boundary and the lower boundary needs to be minimized.

[0078] In this way, the error can be evenly distributed to each distance. If only one distance is used, there is a risk of large surface calculation errors. However, after the errors are evenly distributed, the calculated value can be close to the true value.

[0079] The specific method of statistical distance dispersion is to establish multiple value ranges and group the calculated distances according to the value ranges, and then count the number of values ​​in each group. Here, the ratio of the number of values ​​in a group to the number of all values ​​needs to be greater than a set value, generally in the range of 0.6-0.8, and then calculate the median of this group, which is the average of the maximum and minimum values ​​in the value range of the group.

[0080] The calculated median value is taken as the correct value of the distance, and then the correct value is taken as the arrival time difference of the two corresponding positioning signal waves.

[0081] The present application also provides a global security management device based on the five-defense system, including: A scanning unit is used to scan the information tag on the grounding pile and the identification code on the grounding switch (grounding wire). The information tag is scanned to obtain the unique lock code number and geographical location information of the grounding pile, and the identification code is scanned to obtain the unique number of the grounding switch; A matching unit, used for matching the unique lock code number of the grounding pile with the unique number of the grounding switch; The first communication unit is used to send an unlocking request to the cloud, and the cloud issues an unlocking confirmation code after performing a five-defense logic drill on the unlocking request; A forwarding unit is used to forward the unlocking confirmation code to the five-protection key, and the five-protection key is configured to use an electronic switch belonging to the grounding knife switch (grounding wire); The unlocking application includes at least one grounding switch (grounding wire); When the unlocking application fails to pass the five-defense logic drill, rescan the information label on the grounding pile and the identification code on the grounding switch (grounding wire) or modify the grounding switch (grounding wire) included in the unlocking application.

[0082] Furthermore, when the unlocking confirmation code is used to open the electronic switch belonging to the grounding knife switch (grounding wire), it is necessary to go through cloud audit, which includes scanning audit and position audit; When the unlocking confirmation code issued includes a sequence code, the cloud-based audit only uses the location audit.

[0083] Furthermore, after the five-protection key belonging to the grounding switch (grounding wire) receives the unlocking confirmation code, it sends the received unlocking confirmation code to the cloud. The cloud compares the received unlocking confirmation code with the issued unlocking confirmation code. When the received unlocking confirmation code and the issued unlocking confirmation code are consistent, the cloud sends an unlocking command to the five-protection key.

[0084] Furthermore, it also includes: A position coordinate determining unit, used for determining the number of grounding switches (grounding wires) and the position coordinates of each grounding switch (grounding wire); A first calculation unit, used to calculate the location coordinates of the terminal and generate a movement trajectory according to the location coordinates; The second calculation unit is used to calculate the minimum straight-line distance between the position coordinates of each grounding switch (grounding wire) and the moving track; The second communication unit is used to send the location review result to the cloud when each minimum straight-line distance is less than or equal to the set distance threshold.

[0086] Furthermore, it also includes: A wavelet generating unit, used for generating a wavelet using relevant parameters of the positioning signal wave; A separation unit, used to superimpose the wavelet on the environmental signal and move it, and separate the positioning signal wave emitted by the auxiliary positioning terminal from the environmental signal according to the superimposition and movement result; There are multiple separated positioning signal waves, and each positioning signal wave has a starting time node and an end time node; The positioning signal wave interval at the transmitting position is generated.
