Description

Technical Field

[0001] The present invention relates to the integration of various production equipment terminal protocols in an MES system environment, as well as data adaptation and compatibility issues, and a solution to the problem that unified management and adaptation and compatibility cannot be achieved under various terminal data protocols. Background Art

[0002] In the production process of petroleum, chemical and other types of enterprises, there are many types of intelligent terminal equipment and business management systems at the production site. When connecting with other third-party systems, various incompatibility problems will be encountered. For some specific equipment or communication protocol data sources, specific manufacturers are required to customize and develop special interfaces and special equipment. For enterprises, it will be a large investment in cost management, and maintenance requires high technical personnel. When enterprises face the problem of protocol matching between on-site terminals and business systems and system interfaces in specific environments, most manufacturers on the market have their own MES systems for production plan issuance, auxiliary manufacturing and other scenarios. For the compatibility and adaptation of various types of protocols such as on-site terminal equipment communication protocols, weighing systems, distribution room systems, and business management systems, system debugging and implementation cannot achieve the adaptation of multiple data sources that cannot be managed uniformly. Summary of the invention

[0003] In view of the above specific system environment, the present invention provides and is compatible with a variety of communication protocol formats to achieve data format output in a many-to-one mode. It provides great convenience for technicians in multi-terminal input, format compatibility, equipment debugging and implementation of field terminal equipment. In the production environment of the MES system, input information is flexibly configured through the middleware method. The main functional modules included in the present invention are: data source pool, protocol stack module, protocol conversion engine, dynamic configuration interface, data caching and synchronization, adaptation module, log component, formatted output module and other eight main modules.

[0004] The data source pool module constructs the communication protocols of different devices or different information system exchange packages in the production enterprise into objects that meet the data source pool connection according to certain constraints, and provides link support for its upper-level modules.

[0005] The protocol stack module is a collection of basic protocol driver packages in the present invention, which is an interface for adapting various device data sources in the present invention and a basic resource package for computing work in the system environment of the present invention.

[0006] The protocol conversion engine is a functional module for performing data conversion between different communication protocols, and this module cooperates with other modules of the present invention to work, involving the basic configuration information of the protocol stack module and the dynamically configured interface information, and outputs the converted data packets to the formatted output module according to the definition content of the adapter module.

[0007] The dynamic configuration interface provides an interface for defining output data packets in a system environment, and provides private basic definitions for the data source pool and formatted output modules by defining different configuration information.

[0008] The data cache and synchronization described above is a temporary space for storing intermediate calculation results and output data in the present invention, which improves the operation speed and reduces the number of IO reads and writes. For the same content, the present invention can bypass the algorithm according to the strategy and directly obtain the relevant calculation results from the module.

[0009] The adaptation module is a matching algorithm that completes the three parts of the data source pool, protocol stack and protocol conversion engine, according to the basic data defined in the dynamic configuration interface. On the one hand, the protocol stack and data pool are adapted to the protocol conversion engine, which calculates the adapted result and transfers the result to the data cache and synchronization module, providing a selection algorithm for the formatted output module.

[0010] The log component records the main operation information of the present invention, including four important modules such as the function adaptation module, the protocol conversion engine, the dynamic configuration interface, and the formatted output module. Different levels of log information are constructed respectively to provide different levels of observation of the operation status of the present invention in a specific environment by operation and maintenance personnel.

[0011] The formatted output module is used to format the output according to the format defined in the dynamic configuration interface. It is the docking layer of the upper system environment. The output format is defined according to the requirements of the environment and should be defined in accordance with the requirements of the third-party software environment. It can support multiple output formats.

[0012] Furthermore, the communication protocol of any terminal device can be adapted and converted through this method. According to the parameter settings of the data source connection pool, general content can be configured to standardize the constraints in this method. For example, commonly used parameters include the upper limit gate value of the connection, the survival time of the connection, the type of connection adaptation, etc.

[0013] The compatible protocol types in the protocol stack module, the maximum value of each data transmission, the number of stacks and pop-ups, the maximum number of protocols accommodated, etc., form this internal object after adaptation, and retain the corresponding related attribute information. The output protocol format read by the protocol conversion engine is converted, and the target protocol is encoded and output to complete the process of the present invention.

[0014] Reduce the integration cost of MES system and multi-data source terminal devices. Through the universal protocol parsing and conversion module, there is no need to develop a special interface program for each terminal device, which greatly reduces the development workload and cost.

[0015] Improves the flexibility and scalability of the MES system. New terminal equipment types and communication protocols can be easily added to adapt to the ever-changing needs of industrial production.

[0016] Enhanced the stability and reliability of the MES system. Data caching and synchronization mechanisms ensure data integrity and consistency, reducing system failures caused by data loss or inconsistency.

[0017] Improved data processing efficiency. The protocol conversion engine and data cache mechanism can quickly process a large amount of data from different terminal devices, improving the response speed of the MES system. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The implementation method of the present invention will be described in detail below in combination with examples, including but not limited to the following contents.

[0021] Example 1: Figure 1 The structure shown in the figure is composed of three parts. M1 is the terminal device on the production site, which is connected and started by M2 to start working. The communication data packets of multiple connected terminal devices are output to the specific environment interface of the MES system according to the set format. The components of M2 can run in virtual hosts, physical hosts, gateways or containers. The TCP network is used for data packaging and processing. Finally, the formatted data packets are uniformly delivered to the environment of M3.

[0022] Based on instance 1, configure and deploy the content in M2. Figure 2 The main program starts the entry of the method of the present invention, loads the contents of the S0 files in sequence, and injects the contents into the S5 module for use by other modules.

[0023] In terms of S1 connection processing, multiple terminal device protocols can be added according to the needs of actual work, and S3 will load them according to the dynamic strategy rule S2, and forward them to S4 for formatting the data packet protocol content. During the processing, S6 is responsible for recording important log information in each link and storing it in a file. At the same time, the output format protocol format in the configuration information of S0 is read to match the target output protocol. It is forwarded to the S7 module for closing the frame format, and finally the deployment process of the entire functional module is completed.
