Description

Technical Field

[0001] The present invention relates to the technical field of data transmission, and in particular to an industrial data acquisition and processing system based on wireless transmission technology. Background Art

[0002] In the industrial field, accurate and timely data collection and processing are essential for optimizing production processes, improving product quality, reducing costs, and ensuring safe and reliable operation of equipment. Traditional industrial data collection mainly relies on wired connections. However, with the continuous development and progress of industrial production, this method has gradually exposed some limitations: in large industrial plants or complex production environments, laying a large number of wired connections takes a lot of time, including the procurement, laying, maintenance and modification of cables. Wired connections are also susceptible to physical damage, such as wear, pulling, corrosion, etc., which are difficult to maintain and require professionals to troubleshoot and repair. In recent years, wireless transmission technology has achieved rapid development, with the advantages of high flexibility, easy installation and maintenance, and strong scalability. With the rise of the Industrial Internet of Things (IIoT), more and more industrial equipment and sensors have begun to have networking capabilities, which provides broad application prospects for industrial data acquisition and processing systems based on wireless transmission technology. By combining wireless sensor networks with cloud computing, big data analysis and other technologies, real-time monitoring, intelligent control and optimization decisions of industrial production processes can be achieved. Therefore, the industrial data acquisition and processing system based on wireless transmission technology came into being. It overcomes the limitations of traditional wired data acquisition, combines the advantages of wireless transmission technology and the development trend of industrial Internet of Things, and provides an efficient, flexible and reliable data acquisition and processing solution.

[0003] Chinese patent publication number CN117615342A discloses an AIoT smart gateway working method and system, which involves the field of edge computing and industrial Internet of Things. Specifically, it provides an AIoT smart gateway working method and system, including the following steps: data collection, data transmission, data processing, remote control and self-repair; it can realize multi-sensor long-distance wireless transmission, and compared with traditional wireless sensors, it has low-cost deployment and highly reliable transmission, and can be widely used in signal-free scenarios. It can be seen that the existing technology has the problem of being unable to split data into several acquisition terminals for transmission, and thus being unable to disguise and encrypt the transmitted data, resulting in data transmission risks. Summary of the invention

[0004] To this end, the present invention provides an industrial data acquisition and processing system based on wireless transmission technology to overcome the problem in the prior art that data cannot be split into several acquisition terminals for transmission, and thus cannot be disguised and encrypted for transmission, resulting in data transmission risks.

[0005] To achieve the above object, the present invention provides an industrial data acquisition and processing system based on wireless transmission technology, comprising:

[0006] A data collection module, used to collect industrial characteristic data, including several collection terminals;

[0007] a data processing module connected to the data acquisition module and used to determine disguised data according to the industrial feature data, including a splitting component connected to the plurality of acquisition terminals and used to split the industrial feature data according to the amount of the industrial feature data, and a disguise component connected to the splitting component and used to determine the industrial feature data that needs to be replaced with disguised data according to the number of mappings corresponding to each industrial feature data;

[0008] A data transmission module, which is connected to the data processing module and is used to transmit the industrial characteristic data to a target location, including a plurality of intermediate transmission nodes connected to the plurality of acquisition terminals and used to forward the industrial characteristic data;

[0009] A controller is respectively connected to the data acquisition module, the data processing module and the data transmission module, and is used to determine the transmission position of the disguised data in the intermediate transmission node according to the data volume of the industrial feature data, determine the encrypted position stamp of the industrial feature data according to the transmission position, and determine the type of the industrial feature data to be repaired according to the type loss ratio of the split industrial feature data.

[0010] Furthermore, the disguise component is also used to determine the center-related data according to the industrial characteristic data, and replace the center-related data with the disguise data;

[0011] The central associated data is the industrial feature data having the largest number of mappings.

[0012] Furthermore, the industrial characteristic data includes temperature, pressure, voltage, production progress and quality inspection data of the industrial system.

[0013] Furthermore, the camouflage component is also used to determine the amount of the camouflage data according to the byte amount of the industrial feature data, and to determine the transmission position of the camouflage data in the intermediate transmission node according to the amount of the camouflage data and the transmission order of the camouflage data;

[0014] Among them, the amount of disguised data is positively correlated with the byte amount of the industrial feature data, and the transmission position of the disguised data in the intermediate transmission node is the several intermediate transmission nodes through which the disguised data of the amount is transmitted in the original transmission channel of the disguised data in the transmission order.

[0015] Furthermore, the controller is also used to combine the location stamps according to the information elements of the location stamps of the intermediate transmission nodes to determine the location stamps of the intermediate transmission nodes, and encrypt the location stamps.

[0016] Furthermore, the controller is also used to determine the location stamp of the intermediate transmission node corresponding to the lost industrial feature data according to the type loss ratio of the split industrial feature data, and determine the type of the industrial feature data to be repaired according to the location stamp.

[0017] Furthermore, the type loss ratio of the split industrial feature data is the ratio of the difference between the number of unsplit industrial feature data and the number of split industrial feature data to the number of unsplit industrial feature data.

[0018] Furthermore, the transmission order of the camouflaged data is determined according to the evaluation value of the original transmission channel of the camouflaged data, and the evaluation value of the original transmission channel of the camouflaged data is positively correlated with the transmission priority of the camouflaged data.

[0019] Furthermore, the evaluation value of the original transmission channel of the disguised data is the sum of the product of the bandwidth of the original transmission channel of a single disguised data and the weight coefficient of the bandwidth of the original transmission channel and the product of the number of collection terminals without security risks and the weight coefficient of the number of collection terminals without security risks.

[0020] Furthermore, the collection terminal without security risks is a collection terminal without sudden changes in network traffic.

[0021] Compared with the prior art, the beneficial effects of the present invention are that, by setting up a data acquisition module, a data processing module, a data transmission module and a controller, the present invention determines the disguised data according to the central associated data, thereby reducing the possibility of data being stolen or tampered with during data transmission; an intermediate transmission node is set to forward industrial characteristic data, thereby overcoming the problem that when a node fails, the data can be transmitted through other nodes, and the location of the disguised data is determined by the acquisition terminal, thereby overcoming the problem of data loss or damage during transmission.

[0022] Furthermore, the present invention, by setting up collection terminals, splits the industrial characteristic data and transmits them simultaneously on multiple collection terminals, thereby overcoming the problem of node congestion caused by a single node bearing too heavy a transmission load and improving the speed of data transmission; the data carried by the collection terminals are different, thereby overcoming the problem of complete information leakage when the industrial network is attacked, and achieving improved security of data transmission.

[0023] Furthermore, the present invention sets center-related data and determines the center-related data according to the maximum mapping quantity, thereby overcoming the problem of transmission confusion caused by too many data nodes, which makes it difficult to integrate data, and makes the data processing process clearer.

[0024] Furthermore, the present invention overcomes the problem of being unable to determine the location of the intermediate transmission node and thus being unable to track the original transmission channel of the single disguised data by setting a location stamp of the intermediate transmission node, thereby achieving rapid positioning of the intermediate transmission node; encrypting the location stamp according to a symmetric encryption algorithm overcomes the problem of location information being maliciously attacked and obtained without authorization, thereby improving the compliance requirements for location encryption.

[0025] Furthermore, the present invention sets the type loss ratio of the split industrial characteristic data and can quickly locate the specific location where the problem occurs during data transmission according to the location stamp corresponding to the lost industrial characteristic data, thereby overcoming the situation where the problem location cannot be queried when data is lost or damaged during data transmission. The missing data is restored and backed up in a targeted manner, and the data is repaired by controlling the APP terminal through a controller, thereby achieving rapid repair and optimization.

An industrial data acquisition and processing system based on wireless transmission technology according to the present invention comprises:

[0033] A data collection module, used to collect industrial characteristic data, including several collection terminals;

[0034] a data processing module connected to the data acquisition module and used to determine disguised data according to the industrial feature data, including a splitting component connected to the plurality of acquisition terminals and used to split the industrial feature data according to the amount of the industrial feature data, and a disguise component connected to the splitting component and used to determine the industrial feature data that needs to be replaced with disguised data according to the number of mappings corresponding to each industrial feature data;

[0035] A data transmission module, which is connected to the data processing module and is used to transmit the industrial characteristic data to a target location, including a plurality of intermediate transmission nodes connected to the plurality of acquisition terminals and used to forward the industrial characteristic data;

[0036] A controller is respectively connected to the data acquisition module, the data processing module and the data transmission module, and is used to determine the transmission position of the disguised data in the intermediate transmission node according to the data volume of the industrial feature data, determine the encrypted position stamp of the industrial feature data according to the transmission position, and determine the type of the industrial feature data to be repaired according to the type loss ratio of the split industrial feature data.

[0037] In implementation, the present invention determines disguised data based on central associated data by setting up a data acquisition module, a data processing module, a data transmission module and a controller, thereby reducing the possibility of data being stolen or tampered with during data transmission; an intermediate transmission node is set to forward industrial characteristic data, thereby overcoming the problem that when a node fails, the data can be transmitted through other nodes; and the location of the disguised data is determined by the acquisition terminal, thereby overcoming the problem of data loss or damage during transmission.

[0038] In implementation, the present invention sets up collection terminals to split the industrial characteristic data and transmit them simultaneously on multiple collection terminals, thereby overcoming the problem of node congestion caused by a single node bearing too heavy a transmission load and improving the speed of data transmission; the data carried by the collection terminals are different, thereby overcoming the problem of complete information leakage when the industrial network is attacked, and achieving improved security of data transmission.

[0039] Specifically, the disguise component is further used to determine the central associated data according to the industrial characteristic data, and replace the central associated data with the disguise data;

[0040] The central associated data is the industrial feature data having the largest number of mappings.

[0041] Specifically, the disguised data can be adaptively set according to the content of the industrial feature data, and only needs to be different from the real content of the industrial feature data. The setting process of the disguised data is a conventional technical means well known to those skilled in the art, and the setting process of the disguised data will not be repeated here.

[0042] Specifically, there are several mapping relationships between different data in the industrial characteristic data, and each data in the industrial characteristic data may have a mapping relationship with other data in the industrial characteristic data. Therefore, the maximum number of mappings means the maximum number of mappings between a single data in the industrial characteristic data and other data in the industrial characteristic data.

[0043] In implementation, the present invention sets center-related data and determines the center-related data according to the maximum mapping quantity, thereby overcoming the problem of transmission confusion caused by too many data nodes, which makes it difficult to integrate data, and makes the data processing process clearer.

[0044] Specifically, the industrial characteristic data includes temperature, pressure, voltage, production progress and quality inspection data of the industrial system.

[0045] Specifically, the camouflage component is further used to determine the amount of the camouflage data according to the byte amount of the industrial feature data, and to determine the transmission position of the camouflage data in the intermediate transmission node according to the amount of the camouflage data and the transmission order of the camouflage data;

[0046] Among them, the amount of disguised data is positively correlated with the byte amount of the industrial feature data, and the transmission position of the disguised data in the intermediate transmission node is the several intermediate transmission nodes through which the disguised data of the amount is transmitted in the original transmission channel of the disguised data in the transmission order.

[0047] Specifically, the controller is further used to combine the location stamps according to the information elements of the location stamps of the intermediate transmission nodes to determine the location stamps of the intermediate transmission nodes, and to encrypt the location stamps.

[0048] Specifically, the location stamp information elements include time, altitude, speed, direction, pressure and device number.

[0049] Specifically, the method for encrypting the location stamp can adopt the encryption method in the prior art, and the specific technical means of encryption are not limited. Those skilled in the art can make adaptive settings and selections according to actual scenarios.

[0050] In a specific embodiment, the location stamp information elements are time, speed and direction. The data of the location stamp information elements are represented in binary format. The data are separated by commas to form a string of characters, which is a location stamp. The sender of the symmetric encryption algorithm uses a key to encrypt the plaintext location stamp to convert the plaintext into ciphertext.

[0051] In implementation, the present invention overcomes the problem of being unable to determine the location of the intermediate transmission node and thus being unable to track the original transmission channel of the single disguised data by setting a location stamp of the intermediate transmission node, thereby achieving rapid positioning of the intermediate transmission node; encrypting the location stamp according to a symmetric encryption algorithm overcomes the problem of location information being maliciously attacked and obtained without authorization, thereby improving the compliance requirements for location encryption.

[0052] Specifically, the controller is also used to determine the location stamp of the intermediate transmission node corresponding to the lost industrial feature data according to the type loss ratio of the split industrial feature data, and determine the type of the industrial feature data to be repaired according to the location stamp.

[0053] In a specific embodiment, the types of industrial feature data before splitting are voltage and flow, wherein the number of bytes of voltage data is 1000KB, and the corresponding relationship N between the loss ratio P% of voltage data and the location stamps of intermediate transmission nodes C, D, and E is:

[0054] The number of bytes of the split voltage data is 850KB, and the loss ratio of the voltage data is 100% (1000-850) / 1000=15%. According to the corresponding relationship, the lost voltage data corresponds to the location stamp of the intermediate transmission node D.

[0055] Specifically, the type loss ratio of the split industrial feature data is the ratio of the difference between the number of unsplit industrial feature data and the number of split industrial feature data to the number of unsplit industrial feature data.

[0056] During implementation, the present invention sets the type loss ratio of the split industrial feature data and can quickly locate the specific location where the problem occurs during data transmission according to the location stamp corresponding to the lost industrial feature data, thereby overcoming the situation where the problem location cannot be queried when data is lost or damaged during data transmission. The missing data is restored and backed up in a targeted manner, and the data is repaired by controlling the APP terminal through a controller, thereby achieving rapid repair and optimization.

[0057] Specifically, the transmission order of the camouflaged data is determined according to the evaluation value of the original transmission channel of the camouflaged data, and the evaluation value of the original transmission channel of the camouflaged data is positively correlated with the transmission priority of the camouflaged data.

[0058] Specifically, the evaluation value of the original transmission channel of the disguised data is the sum of the product of the bandwidth of the original transmission channel of a single disguised data and the weight coefficient of the bandwidth of the original transmission channel and the product of the number of collection terminals without security risks and the weight coefficient of the number of collection terminals without security risks.

[0059] In implementation, the sum of the weight coefficient of the bandwidth of the original transmission channel of the single disguised data and the weight coefficient of the number of collection terminals without security risks is 1, the preferred embodiment of the weight coefficient of the bandwidth of the original transmission channel of the single disguised data is 0.4, and the preferred embodiment of the weight coefficient of the number of collection terminals without security risks is 0.6.

[0060] In a specific embodiment, the bandwidth of the original transmission channel T of a single disguised data is 2500 Kbps, and the number of collection terminals without security risks is 20; the bandwidth of the original transmission channel S of a single disguised data is 2000 Kbps, and the number of collection terminals without security risks is 23, and the evaluation value of the original transmission channel T of a single disguised data is 2500×0.4+20×0.6=1012; the evaluation value of the original transmission channel S of a single disguised data is 2000×0.4+23×0.6=813.8, and the evaluation value of the original transmission channel T of a single disguised data is greater than the evaluation value of the original transmission channel S of a single disguised data, that is, the transmission priority of the disguised data corresponding to T is before the transmission priority of the disguised data corresponding to S.

[0061] Specifically, the collection terminal without security risks is a collection terminal with no sudden changes in network traffic.

[0062] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
