It typically connects various isolated information terminals and devices within the market, breaking down information silos and enabling the automatic collection, real-time flow, and unified aggregation of key information such as transaction data, customer flow data, and equipment status within the market.

[0003] In the existing technology, there are many types and protocols of heterogeneous terminal devices in the market. There is usually a lack of unified device function description specifications. This means that when each new or different type of device is connected, customized driver development and integration are required for its specific communication protocol and data format. This makes the device access work fragmented and highly repetitive, which significantly increases the technical complexity and manpower cost of system integration and subsequent maintenance. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies. The unified access adaptation module of this invention standardizes the access of heterogeneous terminal devices through a unified object model description framework. Combined with the centralized template management provided by the object model warehouse module of the cloud collaboration center layer, it greatly reduces the complexity of device access, model updates and iterations.

[0008] The unified access adaptation module is used to connect and manage multiple heterogeneous terminal devices in the market, and convert raw data from heterogeneous terminal devices into standardized event messages and output them to the local real-time message bus module.

[0009] The local real-time message bus module is used to receive the standardized event message and distribute the standardized event message to the edge rule calculation module and the distributed state synchronization module.

[0010] The edge rule calculation module is used to process the received standardized event messages according to preset business rules, and output control commands to the local real-time message bus module or the unified access adaptation module.

[0035] Figure 1 is a system architecture diagram of a smart agricultural trade multi-terminal distributed information interaction and synchronization system proposed in this invention. Detailed Implementation

[0036] 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, and 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.

[0037] Example

[0038] As shown in Figure 1, the present invention provides a technical solution: a smart agricultural trade multi-terminal distributed information interaction and synchronization system, comprising: an intelligent collaborative edge network layer deployed locally in the market, and a remotely set cloud collaborative center layer;

[0039] Specifically:

[0040] The intelligent collaborative edge network layer consists of multiple edge collaborative nodes, each including a unified access adaptation module, a local real-time message bus module, a distributed state synchronization module, and an edge rule calculation module, wherein:

[0041] The unified access adaptation module connects and manages multiple heterogeneous terminal devices within the market, converts raw data from these heterogeneous terminal devices into standardized event messages, and outputs them to the local real-time message bus module. It also includes a unified object model description framework. Based on the standardized functional interface data templates provided by the unified object model description framework, the unified access adaptation module maps heterogeneous terminal devices using different protocols to data objects that are processed internally in a unified manner, and performs the conversion between the raw data and the standardized event messages. The standardized functional interface data templates defined by the unified object model description framework include attributes, services, and events. Specifically:

[0042] The attributes are used to describe the monitorable status and configurable parameters of heterogeneous terminal devices;

[0043] The service is used to define the instructions and parameters that heterogeneous terminal devices can execute remotely;

[0044] The event is used to define the type and payload structure of standardized event messages;

[0045] In the above content, the standardized functional interface data templates provided by the unified object model description framework map heterogeneous terminal devices with different protocols into data objects that are processed internally in a unified manner. The unified access adaptation module first parses the monitorable status and configurable parameters of the heterogeneous terminal devices according to the attribute template, converting raw data such as sensor readings or device status into standardized attribute data. Simultaneously, it defines remotely executable instructions and parameters according to the service template to support the issuance of control commands, and defines the types and load structures of standardized event messages according to the event template. This encapsulates the raw data into standardized event messages with a consistent format and outputs them to the local real-time message bus module. In this design, by standardizing the definitions of attributes, services, and events, the unified access adaptation module can shield the protocol differences of heterogeneous terminal devices, achieving a unified mapping of data objects. This ensures that raw data from diverse devices is efficiently and accurately converted into standardized event messages that the system can process internally. This provides a reliable and consistent data input foundation for subsequent distribution by the local real-time message bus module, processing by the edge rule calculation module, and updates by the distributed state synchronization module, while reducing the complexity of device access and maintenance costs.

[0046] Furthermore, the local real-time message bus module is used to receive the standardized event messages and distribute the standardized event messages to the edge rule calculation module and the distributed state synchronization module. Specifically, the local real-time message bus module is used to publish the standardized event messages according to preset topics, and the edge rule calculation module and the distributed state synchronization module receive the required standardized event messages by subscribing to specific topics.

[0047] In the above, the local real-time message bus module publishes standardized event messages according to preset topics, while the edge rule calculation module and the distributed state synchronization module receive the required standardized event messages by subscribing to specific topics related to their own functions. In this design, the publish-subscribe mechanism decouples message producers and consumers. The local real-time message bus module, as the central message distribution hub, does not need to be aware of the existence or status of specific subscription modules. The topical classification of standardized event messages ensures the targeted and efficient distribution of messages, enabling the edge rule calculation module to obtain event messages that trigger business rule processing in a timely manner. At the same time, the distributed state synchronization module can reliably receive event messages required to update the key state list, thereby supporting real-time response and state synchronization of events within the system and improving the communication flexibility and maintainability between system components.

[0048] Furthermore, the edge rule calculation module is used to process the received standardized event message according to the preset business rules, and output control instructions to the local real-time message bus module or the unified access adaptation module. Specifically, the control instructions output by the edge rule calculation module are transmitted to the unified access adaptation module via the local real-time message bus module. The unified access adaptation module converts the control instructions into an instruction format that can be recognized by the heterogeneous terminal device and sends it out.

[0049] In the above, the edge rule calculation module processes standardized event messages subscribed to and received from the local real-time message bus module according to preset business rules. The edge rule calculation module internally encapsulates configurable logic judgment and execution units. When a standardized event message on a specific topic arrives, the edge rule calculation module matches and calculates the message load according to rule conditions, thereby generating corresponding control instructions. These control instructions are output as new messages to the local real-time message bus module. Furthermore, the instructions are encapsulated as standardized messages on a specific topic and published on the bus, subscribed to and received by the unified access adaptation module. Subsequently, the unified access adaptation module, based on the unified object model... The service templates in the description framework convert internally unified control commands into specific protocol command formats that can be recognized by target heterogeneous terminal devices and then distribute them. This design enables the edge rule calculation module to achieve rapid decision-making and response to events through localized and real-time rule calculation, greatly reducing the latency from event occurrence to control execution. At the same time, control commands are routed and transmitted through the local real-time message bus module, maintaining decoupling and flexibility between system components. Finally, the unified access adaptation module completes the final conversion of the command format, ensuring that the control commands can be accurately applied to diverse terminal devices, thereby realizing closed-loop automatic control based on real-time events.

[0050] Furthermore, the distributed state synchronization module is used to update the local critical state list according to the received standardized event message, and synchronize the critical state list with the distributed state synchronization modules of other edge collaborative nodes through the network. Specifically, the critical state list maintained by the distributed state synchronization module records a state identifier, a state value, and a version number. The distributed state synchronization module updates the state value by exchanging and comparing the version numbers with the distributed state synchronization modules of other edge collaborative nodes to achieve state consistency. After the critical state list in the distributed state synchronization module is updated:

[0051] The local real-time message bus module publishes standardized event messages containing new status values;

[0052] The edge rule calculation module subscribes to the message and triggers the corresponding business rules based on the new status value;

[0053] In the above description, the distributed state synchronization module updates its maintained local critical state list based on standardized event messages subscribed from the local real-time message bus module. The local critical state list records the state identifier, state value, and version number. This design employs a version number-based optimistic concurrency control mechanism. When the module receives an event message, this mechanism updates the corresponding state value and increments its version number. It then exchanges and compares the version numbers of the same state identifier with the distributed state synchronization modules of other edge collaborative nodes via the network. If the local version number is found to be lower than the peer's version number, the local record is updated using the peer's state value and version number; otherwise, the update is ignored or pushed to the local node. This cyclical process of version number comparison and exchange achieves eventual consistency of the critical state lists among all nodes. Once the distributed state synchronization module completes the update of the critical state list... By treating state changes as new event sources, the local real-time message bus module is triggered to publish standardized event messages containing new state values. Upon receiving this message, the edge rule calculation module, which has subscribed to the relevant state topic, will perform condition matching and calculation based on the new state values ​​according to its internal pre-set business rules, thereby triggering the corresponding rule logic. This design, based on a version number-based state synchronization mechanism, can effectively coordinate data updates of multiple edge collaborative nodes in a networked distributed environment, ensuring the consistency of critical states across nodes within the system and avoiding decision conflicts caused by data asynchrony. At the same time, the automatic triggering of new event message publication after a state update instantly transforms the state synchronization results into standardized events that can drive the execution of business rules, realizing an automated link from state change to business response and improving the system's perception and reaction speed to global state changes.

[0054] Furthermore, the cloud collaboration center layer is communicatively connected to the intelligent collaboration edge network layer. The cloud collaboration center layer is used to provide terminal device models, configuration strategies, and business rules to the edge collaboration nodes, and to receive data processed by the edge collaboration nodes for statistical analysis. Specifically, the cloud collaboration center layer includes a material model warehouse module, a strategy and rule management module, and a data lake and analysis module.

[0055] in:

[0056] The object model warehouse module is used to store and manage standardized functional interface data templates for various terminal devices, and provides them to the unified access adaptation module.

[0057] The strategy and rule management module is used to edit the business rules and send them to the edge rule calculation module;

[0058] The data lake and analytics module is used to receive and store data from the edge collaboration nodes, and to perform trend analysis, indicator statistics, and report generation on the data. Specifically:

[0059] Trend analysis of data includes analyzing product sales trends, customer flow trends, or equipment energy consumption trends;

[0060] The data is used to perform statistical analysis, including statistics on total market transaction volume, merchant fulfillment rate, or device online rate.

[0061] Data can be used to generate reports, including daily sales reports, weekly operational reports, or monthly analysis reports.

[0062] In the above, the cloud collaboration center layer connects to the intelligent collaboration edge network layer via a communication link. A centralized management and data aggregation node is established, where the object model repository module stores and manages standardized functional interface data templates for various terminal devices defined by a unified object model description framework. This data is then provided to the unified access adaptation module in the intelligent collaboration edge network layer via the network, enabling the unified access adaptation module to dynamically acquire or update the template data required for device mapping, ensuring the accuracy and scalability of data conversion. The policy and rule management module provides an editing interface and storage repository for business rules, and distributes compiled or configured rules to the edge rule calculation module of the edge collaboration node via the network. The edge rule calculation module loads new rules by receiving update commands, achieving centralized control and remote management of business logic. The deployment process is as follows: The data lake and analytics module receives processed data from edge collaborative nodes, persistently stores heterogeneous data such as time-series data and state snapshots, and performs batch or stream processing analysis tasks based on the stored data. The centralized template management of the object model warehouse module in this design reduces the complexity of maintaining device models on the edge side and ensures the consistency of the entire system's understanding of the devices. The policy and rule management module realizes the unified distribution and version control of business rules, enabling market operation strategies to take effect quickly and consistently on all edge nodes. The data lake and analytics module performs in-depth data analysis through centralized storage and computing resources, which can identify trends from a global perspective, calculate key performance indicators, and generate standardized reports, providing data support for operational decisions while reducing the storage and computing burden on edge nodes.

[0063] In this embodiment:

[0064] At the intelligent collaborative edge network layer, the unified access adaptation module converts the raw data of heterogeneous terminal devices into standardized attribute, service and event data based on the unified object model description framework, forming unified standardized event messages. This design shields the differences in device protocols and provides a consistent data foundation for this invention.

[0065] Then, the standardized event messages are published to the local real-time message bus module. The local real-time message bus module uses a topic-based publish-subscribe mechanism for routing and distribution, which enables the edge rule calculation module to subscribe to and receive event messages that trigger business rules. At the same time, the distributed state synchronization module can subscribe to and receive event messages used to update the local critical state list. This mechanism realizes decoupling and asynchronous communication between modules.

[0066] The edge rule calculation module processes events based on preset rules and generates control commands. The commands are then routed to the unified access adaptation module through the local real-time message bus module and converted into device-specific commands, thus forming a low-latency perception-decision-control closed loop at the edge.

[0067] Furthermore, the distributed state synchronization module utilizes a version number comparison mechanism to synchronize the list of key states through inter-node network communication, ensuring state consistency, and publishes state updates as new events to drive rule calculations that depend on the global state.

[0068] The cloud collaboration center layer centrally manages and distributes device templates to the unified access adaptation module through the object model warehouse module, and centrally edits and distributes business rules to the edge rule calculation module through the policy and rule management module. This enables centralized control and dynamic updates of the core configuration and logic on the edge side. At the same time, the data lake and analysis module aggregates edge data and performs cross-node and cross-time period trend analysis, indicator statistics and report generation.

[0069] Working principle:

[0070] As shown in Figure 1, during operation, the unified access adaptation module connects to heterogeneous terminal devices in the market. Based on the standardized functional interface data templates provided by the unified object model description framework, it converts raw data into standardized event messages and outputs them to the local real-time message bus module. The local real-time message bus module then publishes these standardized event messages according to preset topics. The edge rule calculation module and the distributed state synchronization module receive the required messages by subscribing to specific topics. Simultaneously, the edge rule calculation module processes the messages according to preset business rules, generates control commands, and transmits them to the unified access adaptation module via the local real-time message bus module. The unified access adaptation module converts the control commands into a device-recognizable format and distributes them. The local critical status synchronization module updates its local critical status list based on received messages and synchronizes the critical status list with other edge collaborative nodes' distributed status synchronization modules via the network using a version number comparison mechanism to achieve status consistency. Then, when the critical status list is updated, the local real-time message bus module publishes a standardized event message containing the new status value. The edge rule calculation module subscribes to this message and triggers the corresponding business rules based on the new status value. Finally, the object model warehouse module of the cloud collaboration center layer provides device templates to the unified access adaptation module, the policy and rule management module issues business rules to the edge rule calculation module, and the data lake and analysis module receives and stores data from the edge collaborative nodes, performing trend analysis, indicator statistics, and report generation.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
