[0035] See also Figure 1 , Figure 1 This is a principle block diagram of a data management system according to an embodiment of the present application. Figure 1As shown, the data management system at least includes: a system connection module 110, an inter-system data transmission module 120, a data processing module 130, and a data subscription content management module 140;

[0036] The system connection module 110 is used to realize the communication connection between the first system and the second system, wherein the first system is one of the multiple systems, and the second system is one or more of the multiple systems; wherein each of the multiple systems is independent;

[0037] The system connection module 110 specifies the target system through the IP address and port number. For example, the target system of the first system is the second system. The second system can control whether to publish data. It can only be subscribed after it is opened. The connection is tested to see whether it is available through the IP address and port number. Failed or abnormal connections are notified through alarms and other means. At the same time, the connection is one-way. The first system only cares whether the target (second system) it is connected to is normal. It does not need to care about the status of the device or system connected to the second system. The connection will always remain active to ensure data timeliness. The restart or abnormal connection between the first system and the second system restores the connection through the reconnection mechanism. The connection can be closed / enabled at any time. The MQTT transmission protocol is used, and the heartbeat mechanism and the reconnection mechanism based on the exponential backoff algorithm are used to ensure the stability of the system connection. The connection module is the basis of data sharing.

[0038] In one embodiment, when an abnormality occurs in the communication connection between the first system and the second system, the system connection module reconnects the communication connection between the first system and the second system through a heartbeat mechanism and an exponential backoff algorithm.

[0039] In one embodiment, when an abnormality occurs in the communication connection between the first system and the second system, the system connection module sends a heartbeat request to the first system or the second system, and receives a heartbeat request response from the first system or the second system; when the heartbeat request response is abnormal, an exponential backoff algorithm is used to determine a retry sending interval, and a retry heartbeat request is sent to the first system or the second system again after the retry sending interval until the heartbeat request response is normal.

[0040] An inter-system data transmission module 120, used to implement data transmission between the first system and the second system;

[0041] In one embodiment, the data transmitted by the inter-system data transmission module includes real-time data and historical data, the real-time data is transmitted in a first manner, and the historical data is transmitted in a second manner;

[0042] The first method includes: pushing data through a protocol based on the establishment of a connection;

[0043] The second method includes: obtaining by sending an HTTP request and querying the data according to the unique HASH ID.

[0044] In one embodiment, when performing data transmission, the inter-system data transmission module dynamically compresses the transmitted data according to the system load and hardware performance.

[0045] Assume that system B subscribes to system A, and converts data A into a compact JSON data format before sending it. Then, the compression algorithm is used to compress the JSON. After receiving the compressed data, system B decompresses the compressed package to restore data A. However, compression and decompression will increase additional system performance overhead. The dynamic balance algorithm is used to select whether to compress based on the data volume and system performance consumption, thus balancing data transmission efficiency and system performance overhead.

[0046] In one embodiment, the system load condition includes at least one of the following: the current workload of the system, and the hardware performance condition includes at least one of the following: the processing capacity of the CPU, the processing capacity of the memory, and the processing capacity of the storage.

[0047] Taking the hardware performance including the processing power of the CPU as an example, if the CPU usage is high, the compression usage is reduced, and if the CPU usage is low, the compression usage is increased.

[0048] The data processing module 130 is used to process the associated data of the first system and the associated data of the second system to obtain target data;

[0049] The data processing module converts the new data generated by data processing in the system into data that can be subscribed to by other systems, namely, target data.

[0050] In one embodiment, the data processing module dynamically caches the target data into the memory, and releases the memory after the target data is pushed.

[0051] In one embodiment, a subscription data table is stored in the dynamic cache, and the subscription data table is used to indicate the order of data push; the data processing module is used to determine whether to add the target data to the push queue based on the subscription data table.

[0052] The data subscription content management module 140 is used to publish subscribable information, where the subscribable information includes at least one of the following: associated data of the first system, associated data of the second system, target data of the first system, and target data of the second system.

[0053] The data subscription content management module organizes the information that can be subscribed, including the system data, the system's subscription data, and the system's processed data, and then pushes it to all systems connected to the system. According to the corresponding system subscription, the data is transmitted through the inter-system data transmission module. Through the subscription chain, the system has the ability to obtain data from unconnected remote systems and the ability to forward processed data, such as Figure 2 As shown in FIG, based on this capability, a data aggregation network can be implemented in the system network. Figure 3 , 4 As shown, the system subscribes to data from the target system, and the target system pushes the subscribed content to the system.

[0054] The present invention realizes information interconnection between different systems in the industrial production process through efficient data communication and remote access mechanisms, thereby improving production efficiency and system reliability. It is particularly suitable for complex industrial environments that require high integration and collaborative work, such as intelligent manufacturing and automated production lines that require cross-regional or cross-device data management and control. Industrial scenarios; the present invention implements data filtering through subscription management to reduce the amount of data transmission; and realizes data sharing between multi-level systems. Computation and storage are apportioned to multiple systems, reducing the performance requirements for a single host. In addition, the system can choose to configure redundant servers, and automatically switch redundant systems through a heartbeat monitoring mechanism to ensure stable operation of the system. The present invention also provides functions such as point source data query and historical data tracing, ensures stable connection by using a heartbeat mechanism and a reconnection mechanism, and improves data transmission efficiency through intelligent data compression.

[0055] In one embodiment, the data management system also includes a redundant system, such as Figure 5 shown.

[0056] The redundant system is a module that ensures the stability of system data sharing. When the system is unavailable due to hardware damage, system crash, etc., the redundant system can provide a new connection channel. The heartbeat detection between the systems checks whether they are operating normally. Once the main system is abnormal, the redundant system will start immediately and take over the data communication task through the preset connection channel. This automatic switching function ensures seamless data communication and further improves the stability and availability of the system. This design not only improves the reliability of the system, but also reduces the risk of production interruption caused by system failure.

[0057] The present application also provides an industrial control system, including: Figure 1 The data management system shown.

[0058] The units involved in the embodiments described in this application may be implemented by software or hardware, and the units described may also be set in a processor. The names of these units do not, in some cases, constitute limitations on the units themselves.

[0059] The above embodiments are merely illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
