[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] This invention discloses a method and device for verifying the independence of security control service channels based on a two-dimensional matrix. It is applied to the verification of the independence of security control service channels. Existing technologies employ manual verification, which heavily relies on the experience and capabilities of maintenance personnel. Experienced maintenance personnel must have a deep understanding of the security control service channel arrangement strategy and the current state of the communication network to conduct the verification. The annual security control service channel independence verification work consumes significant human and material resources. Especially during communication system maintenance or failures, and in response to extreme weather and major events, the cost and difficulty of verifying the independence of security control service channels increase exponentially. To address the difficulties of manual verification of security control service channel independence, this invention proposes an automatic verification method for the independence of security control service channels, based on the requirements of the security control service channel arrangement strategy. This method can verify the independence of optical cables and equipment in security control service channels, ensuring the stable operation of the security control system, improving the accuracy of channel arrangement, significantly reducing the workload of maintenance personnel, and increasing their work efficiency. The execution flow of the method is as follows: Figure 1 As shown, the steps include:

[0053] S101. Obtain the current primary security control system and the backup security control system, wherein the primary security control system and the backup security control system contain the same number of master stations, security control service channels, relay stations and optical cable routes;

[0054] In this embodiment of the invention, to ensure the normal operation of the security control service channel, two security control systems are typically used: a primary security control system and a backup security control system. Both systems are equipped with dual security control devices, requiring that the optical cable routes of the transmission channels carried by the two security control devices be completely independent. Preferably, in the event of an anomaly in the primary security control system, the backup security control system is activated. Both the primary and backup security control systems contain the same number of master stations, security control service channels, relay stations, and optical cable routes.

[0055] Preferably, the primary or backup security control system generally consists of one main station, multiple substations, and execution stations. In this embodiment, a simple single-main-station, three-substation star topology security control system is used as an example. Security main station A requires communication channels to transmit information such as handover commands to security substations B, C, and D, necessitating the opening of three security control service channels for each of the two systems AB, AC, and AD. For ease of explanation, it is assumed that AB, AC, and AD all use optical cable segments with two optical repeater stations and three optical cable routes.

[0056] S102. Construct an initial primary security control matrix based on the security control service channels and optical cable routes in the primary security control system;

[0057] In this embodiment of the invention, the first number of the first security control service channels in the primary security control system and the second number of each first optical cable segment in the first optical cable route are obtained respectively. In this embodiment, both the first number and the second number are 3. The optical cable route of the service channels in the primary security control system is defined as an N*M initial primary security control matrix, in which N=3 and M=3. Therefore, the primary security control system can be abstracted as a 3*3 initial primary security control matrix. Assuming that the initial primary security control matrix is ​​H1, all elements of H1 are initialized to the same fixed value, preferably 1 in this embodiment. Each element in H1 represents each first optical cable segment in the primary security control system, and each row represents a security control service channel. H1 is shown below.

[0058]

[0059] S103. Based on the initial primary security control matrix, construct a backup security control matrix and update the initial primary matrix to obtain the primary security control matrix. The backup security control matrix and the primary security control matrix have the same identifier for the same optical cable segment of the optical cable route, and the elements corresponding to different optical cable segments have fixed values.

[0060] In this embodiment of the invention, each second optical cable segment of the second optical cable route in the backup security control system is traversed, and each second optical cable segment is compared with each first optical cable segment to determine whether there are identical optical cable segments. The specific determination process is as follows: obtaining the first optical cable identifier of each first optical cable segment; obtaining the second optical cable identifier of each second optical cable segment, wherein the first optical cable identifier and the second optical cable identifier are used to distinguish different optical cable segments. In this embodiment of the invention, the specific existence form of the first optical cable identifier and the second optical cable identifier is not limited. Each second optical cable identifier is compared with each first optical cable identifier, and corresponding optical cable segments with the same optical cable identifier are determined to be identical optical cable segments.

[0061] For the same optical cable segments in the primary security control matrix and the backup security control matrix, they are replaced with corresponding identical identifiers in the initial primary security control matrix and the backup security control matrix, respectively. In this embodiment of the invention, the specific form of the identifier is not limited. Preferably, the identifier can be i, j, k, etc. The specific processing procedure is as follows:

[0062] If a second optical cable segment is found to have the same position as a first optical cable segment in the primary security control matrix, then the corresponding element of the optical cable segment in the backup security control matrix is ​​defined as i, and the corresponding bit element in the primary security control matrix is ​​modified to i.

[0063] Otherwise, the element corresponding to the optical cable segment is defined as 1 in the backup security control matrix, and the primary control matrix remains unchanged.

[0064] By analogy, the same optical cable segments i, j, k... in the two sets of security control matrices are obtained. Thus, the primary security control matrix H1 and the backup security control matrix H2 are obtained respectively.

[0065] S104. Perform a cross product operation on the primary security control matrix and the backup security control matrix to obtain a verification matrix;

[0066] In this embodiment of the invention, a cross product operation is performed between the transpose of the primary security control matrix and the backup security control matrix, that is, all channels in the primary and backup security control systems are compared one by one to obtain the verification matrix Hc.

[0067] S105. Traverse each element in the verification matrix and determine, based on each element, whether there is a situation where the optical cable routing is not independent in the current security control service channel.

[0068] In this embodiment of the invention, based on the data of elements i, j, k... of the verification matrix and their positions, the specific location information of the non-independent optical cable segments of the security control service channels of the primary and backup security control systems can be obtained, thereby realizing automatic verification of the independence of the optical cables in the security control system channels. If the calculation result of a certain element contains abnormal data, that is, the bit contains multiple i, multiple j, or multiple k... (e.g., i2, 2j, 3k, etc.), it indicates that the security control service channel where the element is located has a non-independent optical cable route; otherwise, the optical cable route of the security control service channel where the element is located is independent.

[0069] This invention discloses a method for verifying the independence of security control service channels based on a two-dimensional matrix, comprising: acquiring the current primary security control system and backup security control system; constructing an initial primary security control matrix based on the security control service channels and optical cable routes in the primary security control system; constructing a backup security control matrix based on the initial primary security control matrix, while simultaneously updating the initial primary matrix to obtain the primary security control matrix; performing a cross product operation on the primary and backup security control matrices to obtain a verification matrix; traversing each element in the verification matrix and determining, based on each element, whether there is a case where the optical cable routes in the current security control service channel are not independent. The above process enables the verification of the independence of security control service channels without relying on the experience and capabilities of maintenance personnel. While ensuring stable system operation and improving the accuracy of security control service channel arrangement, it significantly reduces the workload of maintenance personnel.

[0070] In this embodiment of the invention, an example is given based on the above method. Assume the schematic diagrams of the primary security control system and the backup security control system are as follows: Figure 2As shown, for both the primary security control system and the backup security control system, there is a need for communication channels between the primary security control station A and the security control substations B, C, and D to transmit information such as switchover commands. Therefore, three security control service channels need to be opened for each of AB, AC, and AD. For ease of explanation, it is assumed that AB, AC, and AD all use optical cable segments with two optical repeater stations and three optical cable routes.

[0071] Assume that the optical cable segment A1 between AB in the primary security control system is the same as the optical cable segment C5 between AC in the backup security control system, the optical cable segment B1 between AB in the primary security control system is the same as the optical cable segment C6 between AD in the backup security control system, and the optical cable segment B3 between AD in the primary security control system is the same as the optical cable segment A4 between AB in the backup security control system.

[0072] Define the shared optical cable segment between C5 and A1 as i, the shared optical cable segment between C6 and B1 as j, and the shared optical cable segment between A4 and B3 as k. Based on the traversal results, the backup security control matrix is ​​as follows:

[0073]

[0074] The revised primary security control matrix is ​​as follows:

[0075]

[0076] The primary security control matrix and the transpose of the backup security control matrix are cross-multiplied, that is, all channels in the primary and backup security control systems are compared one by one to obtain the verification matrix Hc.

[0077]

[0078] Furthermore, by analyzing the elements in the verification matrix, and based on the data of the i, j, k... elements and their positions, the specific location information of the non-independent optical fiber sections of the security control service channels of the primary and backup security control systems can be obtained, thus enabling automatic verification of the independence of the optical fiber routes of the security control system channels. If the calculation result of a certain element contains abnormal data, that is, the bit contains multiple i, multiple j, or multiple k... (e.g., i2, 2j, 3k, etc.), it indicates that the security control service channel containing that element has a non-independent optical fiber route.

[0079] For h in the parity check matrix Hc 12 The presence of two 'i's indicates that the optical cable routes of a certain section of channel AB in the primary security control system and channel AC in the backup security control system are not independent; the non-independent optical cable segment is 'i'. 13 The existence of multiple j indicates that the optical cable routes of a certain section of channel AB in the primary security control system and channel AD in the backup security control system are not independent; the non-independent optical cable segment is j; h 31The presence of multiple k indicates that the optical cable routes of a certain section of channel AD in the primary security control system and channel AB in the backup security control system are not independent, and the non-independent optical cable segment is k.

[0080] In this embodiment of the invention, based on a thorough understanding of the characteristics of security control services, and focusing on the essential requirement of channel independence for security control services, a channel independence verification specifically for security control services is conducted for the first time. The concept of two-dimensional matrix operations is introduced to model the security control service channels, enabling simultaneous verification of multiple channels in dual security control systems. This independence verification algorithm is applied to an existing intelligent auxiliary management system, verifying not only the independence of optical cables and equipment in the security control service channels, but also whether the stations along the channel route are shared. The correctness of the algorithm is verified by comparing the results with those of manual verification methods.

[0081] Based on the above-described method for verifying the independence of security control service channels using a two-dimensional matrix, this embodiment of the invention also provides a device for verifying the independence of security control service channels using a two-dimensional matrix. The structural block diagram of the device is shown below. Figure 3 As shown, it includes:

[0087] The calculation module 204 is used to perform a cross product operation on the primary security control matrix and the backup security control matrix to obtain a verification matrix.
