However, if all the data generated by the new energy power grid are transmitted by the Internet of Things, it will affect the dispatching center's control over the new energy power grid. Therefore, the above data needs to be pre-processed and streamlined before transmission. During daily maintenance, maintenance personnel can download data through wired connections and check the operating status of the new energy power grid. The wired download of data provides convenience for criminals to steal the operating data of the new energy power grid, posing a threat to the safe operation of the new energy power grid. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing wired data download provides convenience for criminals to steal the operation data of the new energy power grid, posing a threat to the safe operation of the new energy power grid.

[0006] To solve the above problems, the present invention provides a safety protection system for new energy power grid dispatching, including a detection and analysis module, the detection and analysis module is signal-connected to a data acquisition module, a rapid response module and a communication cooperation module, the data acquisition module is signal-connected to a power grid operation terminal, the communication cooperation module is wirelessly connected to a dispatching center, the communication cooperation module is signal-connected to a data download unit, and the wired connection is realized through a universal interface;

[0007] The universal interface includes a universal interface, the universal interface is plugged with interface 1, one end of interface 1 away from the universal interface is fixedly connected with a data cable, a fixed anchor sheet is provided on the data cable sleeve, the fixed anchor sheet is fixedly connected to the universal interface, one end of the data cable away from interface 1 is fixedly connected with interface 2, one end of interface 2 away from the data cable is plugged with a data download unit, there are multiple different data interfaces on the data download unit, and the data download unit is equipped with multiple communication protocol chips matching different data interfaces;

[0009] In the above-mentioned security protection system for new energy power grid dispatching, the security of new energy power grid operation is increased, and security accidents such as leakage of operation data are less likely to occur.

[0010] As a further improvement of the present application, the communication collaboration module supports multiple communication protocols and interface standards, and the communication collaboration module only realizes wired connection through a single communication protocol at a single time.

[0011] As a further improvement of the present application, the communication protocol implemented by the connection is randomly generated by the communication collaboration module and wirelessly transmitted to the data download unit.

[0012] As a further improvement of the present application, the data acquisition module also has a data preprocessing function to clean, filter and format the collected data, providing an accurate and reliable data basis for subsequent analysis by the detection and analysis module.

[0013] As a further improvement of the present application, the detection and analysis module can timely discover abnormal conditions in the operation of the power grid and issue early warnings by comparing historical data, setting thresholds, etc. The detection and analysis module can also predict potential safety risks based on the characteristics and trends of abnormal data, and provide decision support for the dispatching center.

[0014] As a further improvement of the present application, after interface 1 and the fixed anchor plate are fixed, the gap between the interface and the fixed anchor plate is 2 cm, which reduces the stroke of interface 1 after fixation, makes it difficult for interface 1 to generate enough kinetic energy to destroy the fixation of the fixed anchor plate under the action of external force, and increases the stability of the connection of interface 1.

[0020] When the match is judged to be abnormal, it is determined to be illegal data downloading. While slowing down the data downloading speed, the electric heating device is started to melt the solidified hot melt adhesive filled in the elastic shell, and as the temperature further increases, the elastic shell expands, squeezing and deforming the attached baffle as a whole until the power unit is torn along the direction of its own prefabricated groove. At the same time, the power unit bonded to the hard part moves toward the data downloading unit with the attached fiber. The melted hot melt adhesive will quickly solidify after losing the heat source. During the reaction of the criminal elements, the interface two and the data downloading unit are bonded together, and the interface one can fix the data downloading unit and the interface two because the fixed anchor plate is fixedly connected to the universal interface, so as to prevent the criminals from taking out the operation data of the new energy power grid, and it is not easy to threaten the operation of the new energy power grid. At the same time, when the electric heating device is started, an alarm will be sent to the communication cooperation module, and it will be uploaded to the dispatching center in time, and maintenance personnel will be arranged in time to inspect the area of ​​illegal data downloading, so as to increase the safety of the operation of the new energy power grid and prevent the safety accidents of the operation data leakage.

The type-c interface in the drawings of the specification of this application is taken as an example, and in actual work, it can be replaced by other standard structures;

[0037] The data acquisition module is responsible for real-time collection of operation data of the power grid operation terminal, including key parameters such as voltage, current, and power;

[0038] The detection and analysis module uses advanced data analysis technology to conduct real-time monitoring and analysis of the power grid operation terminal data collected by the data acquisition module;

[0039] When the detection and analysis module finds that the power grid operation terminal data has abnormalities or potential risks, the rapid response module starts the corresponding response mechanism according to the degree of abnormality and risk. The rapid response module can automatically or semi-automatically trigger the corresponding disposal measures according to the preset corresponding mechanism: such as adjusting the power grid parameters, switching the power supply, etc., to ensure the safe and stable operation of the power grid. If the power grid cannot achieve safe and stable operation of the power grid through the preset corresponding mechanism, an alarm will be issued to the personnel, and the maintenance personnel will be contacted to enter the site for processing;

[0040] The communication collaboration module establishes a stable and reliable communication connection to ensure real-time transmission and sharing of data, and realizes real-time information exchange between the new energy grid protection system and the dispatching center, making it easier for the dispatching center to conduct real-time monitoring of the new energy grid protection system and power dispatching.

[0041] See also Figure 2-Figure 6 and Figure 8 The universal interface comprises a universal interface 1, the universal interface 1 is plugged with an interface 1 2, an end of the interface 1 2 away from the universal interface 1 is fixedly connected with a data line 4, the data line 4 is sleeved with a fixed anchor plate 6, the fixed anchor plate 6 is fixedly connected to the universal interface 1, an end of the data line 4 away from the interface 1 2 is fixedly connected with an interface 2 3, an end of the interface 2 3 away from the data line 4 is plugged with a data download unit 7, there are multiple different data interfaces on the data download unit 7, and the data download unit 7 is equipped with multiple communication protocol chips matching different data interfaces, the interface 2 3 comprises an interface body 301, a power groove 302 is cut on the side wall of the interface body 301, an attachment baffle 8 is inserted in the power groove 302, the attachment baffle 8 comprises an elastic portion 801 and a hard portion 802 matching each other, the elastic portion 801 and the power groove 302 The side wall is fixedly connected, the hard part 802 seals the opening of the power groove 302, and a power unit 9 is fixedly connected between the hard part 802 and the bottom plate of the power groove 302. The power unit 9 includes an elastic shell 901, and the elastic shell 901 is filled with solidified hot melt adhesive. An electric heating device 303 is fixedly connected to the bottom plate of the power groove 302. The end of the electric heating device 303 away from the power groove 302 penetrates the elastic shell 901 and extends into the elastic shell 901 to contact with the solidified hot melt adhesive. A prefabricated groove 902 is drilled at one end of the elastic shell 901 close to the hard part 802. A reinforcing net 903 is fixedly connected to the inner wall of the elastic shell 901 close to the hard part 802, and a plurality of attached fibers 904 are fixedly connected to the reinforcing net 903. The plurality of attached fibers 904 are interlaced to form a three-dimensional structure.

[0042] In this application, when maintenance personnel need to perform daily maintenance, they can use the wired connection between the data download unit 7 and the universal interface 1 to realize data download and check the operating status of the new energy power grid. Before data transmission, it will verify whether the current communication protocol and interface match. If they match, it will be determined as normal maintenance work.

[0043] When the match is judged as abnormal, it is determined to be illegal data downloading. While slowing down the data downloading speed, the electric heating device 303 is started to melt the solidified hot melt adhesive filled in the elastic shell 901. Figure 8 , the elastic shell 901 expands, squeezing and deforming the attached baffle 8 as a whole, until the power unit 9 is torn along the direction of the prefabricated groove 902, and at the same time, the power unit 9 bonded to the hard part 802 moves toward the data download unit 7 with the attached fiber 904. The molten hot melt adhesive will solidify quickly after losing the heat source. During the reaction of the criminals, the interface 2 3 and the data download unit 7 are bonded together, and the interface 1 2 is fixedly connected with the universal interface 1 because of the fixed anchor plate 6, so that the data download unit 7 can be fixed to the interface 2 3, preventing the criminals from taking out the operation data of the new energy power grid, and not threatening the operation of the new energy power grid. At the same time, when the electric heating device 303 is started, an alarm will be sent to the communication cooperation module, and it will be uploaded to the dispatching center in time, and maintenance personnel will be arranged in time to inspect the areas where illegal data is downloaded.

[0045] The data acquisition module also has a data preprocessing function to clean, filter and format the collected data, providing an accurate and reliable data basis for subsequent analysis by the detection and analysis module.

The detection and analysis module can also predict potential safety risks based on the characteristics and trends of abnormal data and provide decision support for the dispatching center.

[0047] See also Figure 2-Figure 3 After the interface 2 and the fixed anchor plate 6 are fixed, the gap between the interface 2 and the fixed anchor plate 6 is less than 2 cm, which reduces the stroke of the interface 2 after fixation, making it difficult for the interface 2 to generate enough kinetic energy to destroy the fixation of the fixed anchor plate 6 under the action of external force, thereby increasing the stability of the connection of the interface 2. The universal interface 1 and the fixed anchor plate 6 are fixedly connected with an internal angle screw, and the internal angle screw is of non-standard specification, so as to prevent criminals from removing the fixed anchor plate 6 by standard tools.

[0048] A telescopic device 5 is installed on the data cable 4, and the data cable 4 is wound around the telescopic device 5. The interface 23 is fixedly connected to a counterweight unit, wherein the telescopic device 5 has the same structure and function as the existing automatic wire winder, and can automatically wind up the excess data cable 4 after pulling the interface 23. The interface 23 equipped with the counterweight unit will pull the data cable 4 down a certain distance during the automatic falling process when it is pulled out from the data download unit 7, and trigger the telescopic device 5 to wind up the excess data cable 4 into the telescopic device 5, so as to effectively protect the data cable 4. A high-toughness woven mesh matching the data cable itself is buried in the data cable 4, so as to increase the structural strength of the data cable 4 and prevent the data cable 4 from being directly pulled and broken.

[0049] The second implementation method:

[0050] Figure 9-10 A safety protection system for new energy power grid dispatching is shown, wherein a plurality of capillary cracks 803 are bored on a hard portion 802, and the plurality of capillary cracks 803 completely penetrate the hard portion 802, a reinforcing mesh 903 is distributed in a tooth shape on an elastic shell 901, and a hot pressing groove is formed at the junction of the elastic shell 901 and the reinforcing mesh 903 by hot pressing.

[0051] Compared with the first implementation method, this implementation method further processes the attachment baffle 8 and the power unit 9, so that when the power unit 9 expands and tears, it is easy to tear from the position of the hot pressing groove, and the molten hot melt adhesive will be mostly taken away by the remnant of the elastic shell 901 fixedly connected to the attachment baffle 8 under the action of the attachment fiber 904, and directly contact with the data download unit 7 through the gap of the remnant of the power unit 9 and the capillary crack 803, thereby increasing the connection effect between the data download unit 7 and the interface 2 3, preventing criminals from taking out the operating data of the new energy power grid, and not posing a threat to the operation of the new energy power grid.

[0052] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection.
