Description

Technical Field

[0001] This invention relates to the field of data transmission technology, and more specifically to a method and system for secure multidimensional data transmission based on the Internet of Things. Background Technology

[0002] In the field of intelligent power operation and maintenance, distribution cabinets are the core equipment for realizing power transmission and distribution. Real-time monitoring of their operating status is crucial for ensuring the safe and stable operation of the entire power system. With the deep application and integration of IoT technology in power operation and maintenance scenarios, distribution cabinet status monitoring has gradually developed towards multi-dimensional data collaborative collection. It typically requires the simultaneous collection of various types of information from the distribution cabinet, such as video data, audio data, and environmental data, and the unified uploading of these heterogeneous data to the backend monitoring platform at a preset frequency, thereby providing comprehensive and multi-dimensional data support for power operation and maintenance decisions.

[0003] However, in practical applications, due to the diverse types and large amounts of data collected at the power distribution cabinet, and the need for continuous transmission at a high frequency, the data faces problems such as insufficient security, susceptibility to interference, and low transmission reliability during transmission. This makes it easy for data to be lost, tampered with, or transmitted incorrectly, which in turn leads to the backend platform making analysis and decisions based on erroneous data. Summary of the Invention

[0004] The purpose of this invention is to provide a method and system for secure transmission of multidimensional data based on the Internet of Things (IoT) to address the shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-dimensional data secure transmission method based on the Internet of Things, comprising the following steps: Multiple IoT data collection points are identified, and these points are connected to a data platform. Secure channels are established between each IoT data collection point and the data platform. These secure channels include a packet layer, a transmission channel, and a depacketization area. Multidimensional data is collected from multiple IoT collection points, including video, audio, and text data. The multidimensional data is then packetized to obtain secure data. Secure data is transmitted through a transmission channel until it reaches the data platform for unpacking, where the original multidimensional data is obtained and stored.

[0006] In a preferred embodiment, the step of determining multiple IoT data collection points, connecting the IoT data collection points to the data platform, and establishing secure channels between the multiple IoT data collection points and the data platform includes: The data types collected from multiple IoT collection points are identified and marked. In the data platform, storage space is divided according to the various data types, and the storage space is marked with the data types. A point packet layer is configured at the transmission port of the IoT collection point. The point packet layer stores multiple layer packets. A receiving port is set in the data platform, and a depacketization area is set for the corresponding receiving port. The depacketization area is connected to multiple storage spaces. The transmission port and the unpacking area are connected via a transmission channel.

[0007] In a preferred embodiment, the step of configuring a point packet at the transmission port of the IoT data acquisition point includes: Storage space is configured for the transmission ports of the corresponding IoT collection points, and multiple storage layers are set up within the storage space; Each storage layer stores both fixed and dynamic layers, which are interconnected. The storage space within a storage layer other than the fixed and dynamic layers is used as the load space, and the dynamic layer is bound to the load space.

[0008] In a preferred embodiment, the step of storing a fixed layer and a dynamic layer within each storage layer, with the fixed layer and dynamic layer interconnected, and using the storage space within a storage layer excluding the fixed layer and dynamic layer as load space, and binding the dynamic layer to the load space, includes: Multiple cells are set within the storage layer. These cells are divided into two groups. Each group of cells is sorted according to the same cells, and adjacent cells are connected to each other, resulting in a fixed layer and a dynamic layer. Connect the cells corresponding to the sorting positions of the fixed layer and the dynamic layer with a line; The load space is divided according to the number of cells in the dynamic layer to obtain multiple unit spaces. A corresponding unit carrier is configured in each unit space, and the unit carrier of the unit space is bound one-to-one with the cell in the dynamic layer.

[0009] In a preferred embodiment, the step of collecting multidimensional data based on multiple IoT collection points, wherein the multidimensional data includes video data, audio data, and text data, and packetizing the multidimensional data to obtain secure data, includes: Video, audio, and text data are collected from IoT collection points to form multidimensional data. Multidimensional data is stored through a point packet layer, and secure data is obtained by completing the point packet.

[0010] In a preferred embodiment, the step of storing multidimensional data through a point packet layer to obtain secure data from the point packet includes: A storage layer is randomly selected, and the multidimensional data is evenly stored in the load space. The multidimensional data stored in the cell space is used as the cell data. Connect the cell data to the cell carrier stored in the cell space, and connect the cell carrier to the corresponding cell in the dynamic layer. The positions of cells in the dynamic layer are swapped, and the corresponding unit carriers of the cells are also swapped. When the positions of cells in the dynamic layer are swapped, the line connections between the cells in the dynamic layer and the corresponding cells in the fixed layer are intersected to obtain the intersection points; the line connections between the cells in the dynamic layer and the corresponding cells in the fixed layer corresponding to the intersection points are marked sequentially. After the position swapping of cells in the dynamic layer is completed, the load nodes of the cells in the dynamic layer are moved according to their current sorting position and loaded onto the corresponding cells in the fixed layer to obtain an interleaved network. The line connection between the fixed layer and the dynamic layer is then disconnected to complete the point packet to obtain secure data. Multidimensional data is then backed up at the IoT collection point.

[0011] In a preferred embodiment, the step of transmitting secure data through a transmission channel until it reaches a data platform for unpacking to obtain the original multidimensional data and storing it includes: Secure data is transmitted through a transmission channel, and if the storage layer is accessed during transmission, the secure data is immediately destroyed. The backup multidimensional data is re-packed to obtain secure data for retransmission until it reaches the unpacking area in the data platform. The load nodes of the interlaced network in the secure data are moved back to the corresponding cells in the dynamic layer. The cells in the dynamic layer are reverse-swapped to untangle the interlaced points according to the order of the lines connecting the interlaced points. The cells in the dynamic layer are linked to the corresponding unit carriers for position swapping until all interlaced points are untangled. The unit data in the unit carriers are integrated according to their positions in the unit space to obtain multidimensional data. Multidimensional data is stored in corresponding storage spaces according to its data type.

[0012] This invention also provides a multi-dimensional data security transmission system based on the Internet of Things, including: The configuration module is used to identify multiple IoT collection points, connect the IoT collection points to the data platform, and establish secure channels between the multiple IoT collection points and the data platform. The secure channels include a point packet layer, a transmission channel, and a depacketization area. The sending and processing module, connected to the setting module, is used to collect multidimensional data based on multiple IoT collection points. The multidimensional data includes video data, audio data, and text data. The multidimensional data is then processed into packets to obtain secure data. The transmission parsing module, connected to the sending processing module, is used to transmit secure data through the transmission channel until it reaches the data platform for unpacking, obtaining the original multidimensional data, and storing it.

[0013] The technical effects and advantages provided by the present invention in the above technical solution are as follows: This invention enables the exchange and scrambling of multidimensional data through a point packet layer, and records the scrambling process through a fixed layer. This recording is used for reassembling the multidimensional data in the subsequent unpacking area. It offers a high level of encryption, timely response and destruction during transmission, and a reaction period during destruction. Even if some data is acquired, unauthorized networks cannot obtain accurate multidimensional data as it remains scrambled and uncombinable, ensuring the security of multidimensional data during transmission. After transmission to the unpacking area, the interleaved network recorded by the fixed layer is then assigned to a dynamic layer. The dynamic layer redistributes the unit data until it is swapped back to its original position, allowing for reassembly to obtain the original multidimensional data. Attached Figure Description

Obviously, the drawings described below are only some embodiments recorded in this invention. For those skilled in the art, other drawings can be obtained based on these drawings.

[0016] Figure 2 This is a system block diagram of the present invention. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0018] Example 1, please refer to Figure 1 As shown in this embodiment, the multi-dimensional data secure transmission method based on the Internet of Things includes the following steps: S1. Identify multiple IoT collection points, connect the IoT collection points to the data platform, and establish secure channels between the multiple IoT collection points and the data platform respectively. The secure channel includes a point packet layer, a transmission channel, and a depacketization area. S2. Collect multidimensional data based on multiple IoT collection points. The multidimensional data includes video data, audio data, and text data. Pack the multidimensional data into points to obtain secure data. S3. Transmit secure data through the transmission channel until it reaches the data platform for unpacking, obtain the original multidimensional data, and store it.

[0019] As described in steps S1-S3 above, when monitoring the operation of the power distribution cabinet, it is necessary to collect video data around the cabinet for surrounding safety monitoring, collect audio data to understand whether there is noise from the cabinet, and collect air data, such as temperature and humidity, to form text data, which is then transmitted at a preset frequency. The point packet layer can perform exchange and scrambling of multidimensional data, and the fixed layer can record the scrambling process for subsequent multidimensional data reassembly in the unpacking area. This provides a high degree of encryption and timely response and destruction during transmission. There is a reaction period during destruction; even if some data is acquired, unauthorized networks cannot obtain accurate multidimensional data, as it is scrambled and cannot be reassembled. After transmission to the unpacking area, the interleaved network recorded by the fixed layer is then assigned to the dynamic layer. The dynamic layer redistributes the unit data until it is swapped back to its original position, allowing for reassembly to obtain the original multidimensional data. This ensures the security of multidimensional data during transmission.

[0020] In one embodiment, step S1, which involves determining multiple IoT data collection points, connecting the IoT data collection points to a data platform, and establishing secure channels between the multiple IoT data collection points and the data platform respectively, includes: S11. Confirm and mark the data types collected by multiple IoT collection points, divide the storage space in the data platform according to the various data types, and mark the data types in the storage space. S12. Configure a point packet layer at the transmission port of the IoT collection point. The point packet layer stores multiple layer packets. Set a receiving port in the data platform and set a depacket area for the corresponding receiving port. The depacket area is connected to multiple storage spaces. S13. The transmission port and the unpacking area are connected through a transmission channel.

[0021] In one embodiment, step S12, configuring the point packet layer at the transmission port of the IoT acquisition point, includes: S121. Configure storage space for the transmission port of the corresponding IoT collection point (the storage space is the storage space of the IoT collection device, where the IoT collection device is the IoT collection point), and set up multiple storage layers in the storage space. S122. Each storage layer stores a fixed layer and a dynamic layer, which are interconnected. The storage space in the storage layer other than the fixed layer and the dynamic layer is used as the load space, and the dynamic layer is bound to the load space.

[0022] In one embodiment, step S122, which involves storing a fixed layer and a dynamic layer within each storage layer, interconnecting the fixed and dynamic layers, and using the storage space within a storage layer excluding the fixed and dynamic layers as load space, and binding the dynamic layer to the load space, includes: S1221. Set up multiple cells in the storage layer. The multiple cells are divided into two groups. The cells in each group are sorted according to the same cells. Adjacent cells are connected to each other to obtain a fixed layer and a dynamic layer. S1222. Connect the cells corresponding to the sorting positions of the fixed layer and the dynamic layer with a line; S1223. Divide the load space according to the number of cells in the dynamic layer to obtain multiple unit spaces. Configure the corresponding unit carrier in each unit space and bind the unit carrier of the unit space to the cell in the dynamic layer one-to-one.

[0023] As described in steps S11-S13 above, the data types collected by multiple IoT collection points are confirmed and marked. Since the data types collected by IoT devices differ—for example, some IoT devices collect video and audio data, while others collect text data—the data types of each IoT collection point are marked. Different types of data need to be stored separately in the data platform. Therefore, the data platform is divided into storage spaces corresponding to various data types, and the data types are marked. After this setup, storage space is configured for the transmission ports of the corresponding IoT collection points. Multiple storage layers are set up within the storage space. Each storage layer serves as a transmission carrier for multidimensional data. Here, it is a virtual machine capable of storing relatively large amounts of data. Each storage layer is configured with fixed and dynamic layers. Both fixed and dynamic layers consist of multiple identical cells, distributed according to the same sorting relationship. Cells are interconnected, with corresponding connections between fixed and dynamic layers (line connections). Specifically, these line connections are mappings between corresponding cells in the dynamic and fixed layers, forming a logical line connection. The load space is used to store multidimensional data later. To manage the cells corresponding to multidimensional data, the load space is divided into multiple units. The load space is distributed according to a flat spatial layout logic, and then divided according to the number of cells in the dynamic layer, resulting in multiple unit spaces. Each unit space stores a corresponding unit carrier, which is a virtual data carrier stored in the unit space for storing the unit data of the multidimensional data later. A one-to-one binding connection is established between the unit carriers in the unit space and the corresponding cells in the dynamic layer, thus establishing the relationship between the load space and the dynamic layer. This allows the data in the load space to be encrypted through the dynamic and fixed layers, ensuring secure transmission.

[0024] In one embodiment, the step S2, which involves collecting multidimensional data based on multiple IoT collection points, wherein the multidimensional data includes video data, audio data, and text data, and performing point-packet analysis on the multidimensional data to obtain secure data, includes: S21. Collect video, audio, and text data from IoT collection points as multi-dimensional data; S22. Store the multidimensional data through the point packet layer to obtain secure data by completing the point packet.

[0025] In one embodiment, step S22, which involves storing multidimensional data through a point packet layer to obtain secure data from the point packet, includes: S221. Randomly select a storage layer, uniformly store multidimensional data in the load space, and use the multidimensional data stored in the cell space as cell data; S222. Connect the cell data to the cell carrier stored in the cell space, and connect the cell carrier to the corresponding cell in the dynamic layer. S223. Swap the positions of the cells in the dynamic layer. The cells are linked to the corresponding unit carriers for position swapping. When swapping the positions of the cells in the dynamic layer, the line connections between the cells in the dynamic layer and the corresponding cells in the fixed layer are intersected to obtain the intersection points. The line connections between the cells in the dynamic layer and the corresponding cells in the fixed layer corresponding to the intersection points are marked sequentially. S224. After the position swapping of cells in the dynamic layer is completed, the load nodes of the cells in the dynamic layer are moved according to their current sorting position and loaded onto the corresponding cells in the fixed layer to obtain an interleaved network. The line connection between the fixed layer and the dynamic layer is disconnected to complete the point packet to obtain secure data. Multidimensional data is backed up at the IoT collection point.

[0026] As described in steps S21 and S22 above, after collecting multidimensional data at the IoT collection point, the multidimensional data is transmitted at a preset frequency. A storage layer is randomly selected, and the multidimensional data corresponding to the current preset frequency is stored in the load space. The multidimensional data is evenly stored in the load space according to the data volume. The multidimensional data is isolated through the unit space to obtain unit data, which is stored in the unit carrier. The unit space, as the space of the load unit carrier, does not move. The unit carrier can move with the movement of the cells in the dynamic layer, thereby exchanging unit data and causing the multidimensional data to be transmitted in a disordered manner. Even if it is obtained before destruction, it cannot understand the real data, ensuring that it is not stolen or understood during the data transmission process. The positions of the cells in the dynamic layer are swapped, and the cells are linked to the corresponding unit carriers for position swapping. When the positions of the cells in the dynamic layer are swapped, the line connections between the cells in the dynamic layer and the corresponding cells in the fixed layer are intersected, and temporary points are used as intersecting points. Intersection points are used to sequentially mark the line connections between cells in the dynamic layer and corresponding cells in the fixed layer. For example, in a dynamic layer and four cells in the fixed layer deployed in a grid pattern, if two diagonal cells in the dynamic layer are swapped, the logical lines connecting them will intersect. At this point, a temporary point (virtual machine) is used to mark the intersection point and bind the temporary point to the two lines that created the intersection. This intersection point is then bound to a temporary point of two lines as an intersection point. Subsequently, if two diagonal cells in the dynamic layer are swapped, the lines of these two cells will also intersect. If the dynamic layer is logically stored above the fixed layer, the intersection point formed by the swapping of cells in the dynamic layer will be above the previous intersection point. Another temporary point is then used at this intersection point and bound to two lines to obtain the next intersection point, which is above the previous intersection point. Therefore, there is a sequence, and the sequence is marked and recorded at the corresponding intersection points.After the cells in the dynamic layer have finished swapping positions, the load nodes of the cells in the dynamic layer are moved according to their current sorting position and loaded onto the corresponding cells in the fixed layer, resulting in an interleaved network. For example, after the four cells in the dynamic layer and the fixed layer deployed in a grid pattern are swapped diagonally, the cells in the dynamic layer are connected to the cells in the fixed layer through load nodes. Therefore, to isolate the fixed layer from the dynamic layer, the load nodes are disconnected from their corresponding cells. There are no load nodes in the fixed layer. Then, the load nodes are moved to the corresponding cells in the fixed layer after the swap, breaking the line connection between the fixed layer and the dynamic layer. The load nodes and interleaved points will all be loaded onto the cells in the fixed layer, forming a record of the swapping path of the cells in the dynamic layer. This facilitates the subsequent recovery of multidimensional data, thus completing the point packet of multidimensional data to obtain secure data. Before completing the point packet, the multidimensional data needs to be backed up at the IoT acquisition point to avoid transmission failure.

[0027] In one embodiment, step S3, which involves transmitting secure data through a transmission channel until it reaches a data platform for unpacking to obtain the original multidimensional data and then storing it, includes: S31. Transmit the secure data through the transmission channel. If the storage layer is accessed during transmission, the secure data shall be destroyed immediately. S32. Re-packetize the backed-up multidimensional data to obtain secure data for retransmission until it reaches the unpacking area in the data platform. Move the load nodes of the interlaced network in the secure data back to the corresponding cells in the dynamic layer. According to the order of the lines connecting the interlaced points, reverse the swapping of the cells in the dynamic layer to untangle the interlaced points. The cells in the dynamic layer are linked with the corresponding unit carriers to swap positions until all interlaced points are untangled. Integrate the unit data in the unit carriers according to their positions in the unit space to obtain multidimensional data. S33. Store multidimensional data in the corresponding storage space according to the data type.

[0028] As described in steps S31-S33 above, secure data is transmitted through a transmission channel. During transmission, if the storage layer of the secure data is accessed, the secure data is immediately destroyed. The fixed layer is disconnected from the storage layer, dynamic layer, and load space within the storage layer; it is an independent space. While the fixed layer is secure when accessed, unauthorized access during transmission results in the entire storage layer being destroyed. The storage layer containing the fixed layer is destroyed, and the fixed layer is destroyed along with it. During the destruction reaction period, even if some unit data in the load space is acquired, it cannot be combined, making it difficult to obtain true multidimensional data, thus providing good data protection. After destruction, the secure data is retransmitted based on the backed-up multidimensional data through packet retransmission until it reaches the unpacking area in the data platform. The load nodes of the interleaved network in the secure data are moved back to the corresponding cells in the dynamic layer and connected according to the lines corresponding to the interleaved points. The sequential markers in the dynamic layer reverse the swapping of cells to untangle the intersecting points. If the cells are not swapped in sequence, the lines corresponding to the intersecting points will become even more intersecting and cannot be untangled. The temporary points corresponding to the untangled intersecting points will be detached and put back into a standby state. The temporary points are stored in the storage layer. The cells in the dynamic layer are linked with the corresponding unit carriers to swap positions until all intersecting points are untangled. The unit data in the unit carriers are integrated according to their positions in the unit space. Here, adjacent unit data are combined to obtain multidimensional data. The point packet layer can be used to exchange and scramble the multidimensional data, and the scrambling method can be recorded by the fixed layer for subsequent multidimensional data recombination in the unpacking area. The encryption level is high, and the data is promptly responded to and destroyed during transmission. There is a reaction period during the destruction process. Even if some data is obtained, the unauthorized network cannot obtain accurate multidimensional data, as it is all randomly distributed and cannot be combined. After being transmitted to the unpacking area, the data is reassigned to the dynamic layer through an interleaved network recorded in the fixed layer. The dynamic layer then redistributes the unit data until it is swapped back to its original position before it can be combined to obtain the original multidimensional data. This ensures the security of the multidimensional data during transmission.

[0029] Example 2, please refer to Figure 2 As shown in this embodiment, the multi-dimensional data security transmission system based on the Internet of Things includes: The configuration module is used to identify multiple IoT collection points, connect the IoT collection points to the data platform, and establish secure channels between the multiple IoT collection points and the data platform. The secure channels include a point packet layer, a transmission channel, and a depacketization area. The sending and processing module, connected to the setting module, is used to collect multidimensional data based on multiple IoT collection points. The multidimensional data includes video data, audio data, and text data. The multidimensional data is then processed into packets to obtain secure data. The transmission parsing module, connected to the sending processing module, is used to transmit secure data through the transmission channel until it reaches the data platform for unpacking, obtaining the original multidimensional data, and storing it.

[0030] It should be noted that the point packet layer can perform scrambling and swapping of multidimensional data, and the fixed layer can record the scrambling process for subsequent reassembly in the unpacking area. This provides a high level of encryption and timely response and destruction during transmission. There is a reaction period during destruction; even if some data is obtained, unauthorized networks cannot obtain accurate multidimensional data, as it will be scrambled and uncombinable. After transmission to the unpacking area, the interleaved network recorded by the fixed layer is then assigned to the dynamic layer. The dynamic layer redistributes the unit data until it is swapped back to its original position, allowing for reassembly to obtain the original multidimensional data. This ensures the security of multidimensional data during transmission.
