Description

Technical Field

[0001] The present invention relates to the technical field of intelligent monitoring of power systems, and in particular to an intelligent monitoring device and method for a standard modular substation. Background Art

[0002] In the development of the power system, substations, as a core component of power grid operation, have also experienced significant progress in monitoring technology. Traditional substation monitoring usually relies on manual inspections or single sensor monitoring modes, which makes it difficult to obtain detailed status information in the substation in real time, especially in complex environments or emergency situations. With the continuous development of power automation and intelligent technology, substation monitoring is gradually moving towards intelligence, modularization and integration. The existing intelligent monitoring systems mostly combine cameras, sensors and other equipment to collect the operating status of substations through image and video data, and use communication systems to transmit information to remote control platforms to achieve remote management. However, traditional monitoring devices have certain limitations in information transmission, data encryption and real-time control, and are mostly customized designs without modular advantages, making it difficult to adapt to the diverse needs of different substations.

[0003] Although the existing technology has achieved intelligent monitoring of substations to a certain extent, it still has many shortcomings in terms of security, real-time performance, flexibility, etc. First, most of the current image and video transmission solutions do not effectively encrypt and protect the transmission content, and the data is vulnerable to network attacks during transmission, which is not secure enough. Secondly, traditional monitoring devices are mostly fixed-angle camera equipment, lacking a flexible pan-tilt control mechanism, resulting in blind spots when monitoring key areas, and unable to achieve all-round real-time monitoring. In addition, most of the existing technologies are non-modular designs with poor scalability, making it difficult to adapt to the personalized needs of different substations. These technical bottlenecks restrict the further development of intelligent substation monitoring systems. A standard modular substation intelligent monitoring device and method invented by us integrates modules such as mainboard, power supply, lighting control, communication, motor control, and lens movement through modular design, and realizes encrypted transmission of image data and intelligent control of the pan-tilt, which can effectively solve the above technical problems. Summary of the invention

[0004] In view of the above-mentioned problems, the present invention is proposed.

[0005] Therefore, the technical problem solved by the present invention is: the current substation monitoring system generally lacks effective encryption measures when transmitting image and video information to the upper-level platform, which makes the data vulnerable to network attacks and interception, and there are great security risks. The existing substation monitoring systems mostly use fixed-angle camera equipment, which is difficult to achieve dynamic monitoring and is prone to monitoring blind spots in key areas. Due to the large amount of image and video data, the traditional monitoring system directly transmits the information to the upper-level platform for processing after information collection, which is easy to cause transmission congestion due to data redundancy, affecting the real-time responsiveness of monitoring. Due to the large amount of image and video data, the traditional monitoring system directly transmits the information to the upper-level platform for processing after information collection, which is easy to cause transmission congestion due to data redundancy, affecting the real-time responsiveness of monitoring.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a standard modular substation intelligent monitoring device, which comprises the following steps:

[0007] Main board module, power module, lighting control module, communication module, motor control module and lens movement module.

[0008] As a preferred solution of a standard modular substation intelligent monitoring device described in the present invention, wherein: the mainboard module is used to carry a power module, a lighting control module, and a communication module;

[0009] The power supply module provides power to the lighting control module, the communication module, the motor control module and the lens movement module.

[0010] The light control module controls the camera fill light.

[0011] The communication module is responsible for communicating with the upper-level platform and transmitting data.

[0012] The motor control module controls the movement of the camera pan / tilt.

[0013] The lens movement module is responsible for collecting image and video information.

[0014] Another object of the present invention is to provide a standard modular substation intelligent monitoring method, which can realize real-time acquisition, preprocessing, encrypted transmission and precise control of the pan-tilt head of image and video data through modular design and intelligent control means, thereby solving the problems of lack of flexibility, insufficient data transmission security, blind spots in monitoring view and low real-time response speed of existing substation monitoring systems.

[0015] In order to solve the above technical problems, the present invention provides the following technical solutions: a standard modular substation intelligent monitoring method, comprising:

[0016] The image and video information is collected through the lens movement module; the image and video information is transmitted to the upper-level platform through the communication module; the upper-level platform makes judgments based on the image and video information and generates control instructions; the motor control module controls the movement of the gimbal according to the control instructions.

[0017] As a preferred solution of the standard modular substation intelligent monitoring device described in the present invention, the image and video information are collected and preprocessed, including removing noise from the image and enhancing the color of the image.

[0018] As a preferred solution of a standard modular substation intelligent monitoring device described in the present invention, the transmission of image and video information to the upper-level platform includes encrypting the image and video information. If the collected image and video information is greater than the transmission capacity threshold, the image and video information is cut and encrypted. If the collected image and video information is less than or equal to the transmission capacity threshold, it is directly encrypted.

[0019] The encryption includes that the upper-level platform generates a public key and a private key before transmitting the image and video information to the upper-level platform, sends the public key to the lens movement module, the lens movement module encrypts the image and video information according to the public key, and transmits it to the upper-level platform, and the upper-level platform decrypts it according to the private key.

[0020] As a preferred solution of a standard modular substation intelligent monitoring device described in the present invention, the judgment based on image and video information includes combining with pre-set point information to determine whether the current camera viewing angle covers the abnormal situation.

[0021] As a preferred solution of a standard modular substation intelligent monitoring device described in the present invention, wherein: the generating control instruction includes, if the abnormal situation is not covered, generating an instruction to adjust the control pan-tilt platform.

[0022] As a preferred solution of the standard modular substation intelligent monitoring device described in the present invention, the generating control instruction also includes, if there is different point information, processing according to the priority of different points.

[0023] A computer device comprises a memory and a processor, wherein the memory stores a computer program, and the processor implements the steps of the above-mentioned standard modular substation intelligent monitoring method when executing the computer program.

[0024] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements the steps of the above-mentioned standard modular substation intelligent monitoring method.

[0025] Beneficial effects of the present invention: The present invention uses dynamically generated public and private keys for asymmetric encryption, realizes dual security protection from the physical link and data content, effectively prevents man-in-the-middle attacks and data tampering, divides image and video data into blocks and encrypts them independently, which not only enhances the security of the data, but also makes it difficult to decipher a single data block even if it is leaked during transmission because it is not accompanied by other data content. The integrity of each block of data is confirmed by hash verification, ensuring lossless transmission of data from collection to decryption, and judging whether the data needs to be transmitted in blocks by capacity threshold detection, avoiding transmission congestion or delay that may occur when transmitting large data packets. At the same time, the block transmission method supports parallel data processing, speeds up transmission speed, and improves the system's responsiveness under large data volume conditions.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0030] Example 1, reference Figure 1 , is an embodiment of the present invention, and provides a standard modular substation intelligent monitoring device, characterized in that:

[0031] Main board module, power module, lighting control module, communication module, motor control module and lens movement module.

[0032] The mainboard module is used to carry the power module, lighting control module, and communication module.

[0033] The power module provides power for the lighting control module, communication module, motor control module and lens movement module.

[0034] The light control module controls the camera fill light.

[0035] The communication module is responsible for communicating with the upper-level platform and transmitting data.

[0036] The motor control module controls the movement of the camera pan / tilt.

[0037] The lens movement module is responsible for collecting image and video information.

[0038] Example 2, reference Figure 2 , as an embodiment of the present invention, provides a system of standard modular substation intelligent monitoring device, characterized in that:

[0039] S1: Collect image and video information through the lens movement module.

[0040] After collecting image and video information, preprocessing is performed, including removing noise from the image and enhancing the color of the image.

[0041] Furthermore, after collecting the image and video information, identifiers are added to the image and video information.

[0042] S2: Transmit image and video information to the upper-level platform through the communication module.

[0043] Transmitting the image and video information to the upper level platform includes encrypting the image and video information, cutting the image and video information and encrypting it if the collected image and video information is greater than the transmission capacity threshold, and directly encrypting it if the collected image and video information is less than or equal to the transmission capacity threshold;

[0044] The encryption includes that the upper-level platform generates a public key and a private key before transmitting the image and video information to the upper-level platform, sends the public key to the lens movement module, and the lens movement module encrypts the image and video information according to the public key and transmits it to the upper-level platform, and the upper-level platform decrypts it according to the private key;

[0045] Furthermore, the public key must be sent to the lens core module within the specified time. The lens core module binds the public key to the identifier and returns it to the upper-level platform. If the lens core module does not receive the public key within the specified time, it is automatically deemed to be timed out and invalid, and the upper-level platform must regenerate the public key. The above steps are only performed on the unblocked image and video information;

[0046] If the image and video information has been divided into blocks, the public key is used to independently encrypt each data block. After encryption, each block of data is accompanied by its corresponding hash value so that the platform can decrypt and verify it. The encrypted data blocks are repackaged in sequence, and the data block sequence identifier and timestamp are attached to ensure that they are not out of order during transmission.

[0047] Encrypted communication before image and video information is transmitted to the upper-level platform is an important part of ensuring data security. When transmitting information, judging whether to encrypt in segments based on the preset transmission capacity threshold can improve the transmission efficiency of the system. For example, if the collected data is larger than the transmission capacity, segmented encryption can avoid delays or packet loss during transmission. In addition, the encryption and decryption mechanism of public and private keys ensures that data is not stolen or tampered with during transmission. The beneficial effect of this step is that it ensures the confidentiality and integrity of information during transmission, and improves the data's anti-attack and system security.

[0048] S3: The upper-level platform makes judgments based on the image and video information and generates control instructions.

[0049] Judging based on the image and video information includes combining it with pre-set point information to judge whether the current camera viewing angle covers the abnormal situation.

[0050] Generating the control instruction includes, if the abnormal situation is not covered, generating an instruction to adjust the control pan / tilt platform.

[0051] Generating the control instruction also includes, if different point information exists, processing according to the priority of different points.

[0052] To further supplement, how to judge the priority of different points, set the priority according to the risk level of different point areas, if there are two or more point information that do not cover the abnormal situation, the gimbal instructions are generated in sequence according to the set priority.

[0053] S4: The motor control module controls the movement of the gimbal according to the control instructions.

[0054] Furthermore, by explicitly specifying the pitch angle and horizontal angle of the gimbal in the control command, the gimbal can be adjusted according to actual needs to prevent excessive rotation or deviation.

[0055] Controlling the motion of the PTZ according to the control instructions is the key to the system's closed-loop control. By clearly specifying the pitch and horizontal angles of the PTZ in the control instructions, the PTZ can accurately locate the specified point area to prevent problems such as excessive rotation or viewing angle deviation. For example, after setting different point viewing angle parameters, the system gradually adjusts the PTZ according to the priority so that it covers the unmonitored point areas one by one. This step is to ensure the integrity and continuity of the monitoring range, while avoiding unnecessary rotation and extending the service life of the equipment.
