Description
Technical Field
The invention relates to a data communication method, in particular to a data communication method based on a factory method mode and a dynamic loading module.
Background
Factory method modes, also known as factory modes, polymorphic factory modes and virtual builder modes, define a factory parent class that is responsible for defining the common interface for creating objects, and subclasses that are responsible for generating specific objects.
The factory method model defers the creation of a particular product to a subclass of factory classes (a particular factory) where the factory classes are no longer responsible for the creation of all products, but rather only present the interfaces that the particular factory must implement. When a new product is added, the logic of the plant class is not required to be modified, and a new plant subclass is expanded. Thus, the advantages of the package object creating process are maintained, and meanwhile, the open and closed principle is still met.
For a long time, the demand for data communication functions has been the key and pain point of the industries such as electric power and energy. In the current industry, a mature and stable solution is provided for various international/domestic standard communication protocols. However, the following two major disadvantages remain:
1. only one or a few communication protocols can be adapted, and the expansion is not possible. Once a new communication protocol appears, only the software product can be reconstructed and even re-developed.
2. A simple factory model is used to match different communication protocols. The number of communication protocols that this kind of product can adapt to is not very small, but the defect of the simple factory model itself (not conforming to the open closure principle) that when a new communication protocol appears, the factory class logic needs to be modified, and the product code needs to be changed and recompiled. Therefore, the original performance and stability of the product cannot be ensured.

Detailed Description
The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.
As shown in fig. 1, the data communication method based on the factory method mode and the dynamic loading module according to the present invention is to cope with the situation that the communication protocol of the data input terminal is different from the communication protocol of the data output terminal, that is, the first communication protocol is executed at the data input terminal and the second communication protocol is executed at the data output terminal.
Thus, in order to adapt to multiple types of communication protocols and perform data interaction, as shown in fig. 1, the present invention includes the following steps:
In this step 101, the first communication protocol information and the second communication protocol information may be acquired by reading the master profile.
Table 1 below shows a main configuration file information structure, and as can be seen from the table, the first communication protocol information and the second communication protocol information can be obtained by reading the main configuration file through the meaning information corresponding to the specific field name.
Table 1:
| name of field | Means of |
| INPUT/BasePath | Subfolders of first communication protocol(s) configuration file |
| IO/Output | Filename of second communication protocol type configuration file |
And 102, selecting and loading a dynamic link library of a corresponding communication function module by the factory according to the first communication protocol information and the second communication protocol information.
In this step, the factory searches the existing dynamic link library of the corresponding communication function module according to the first communication protocol information and the second communication protocol information and according to a pre-specified path. And if the existing dynamic link library of the corresponding communication function module is found, loading the dynamic link library for subsequent steps. If no dynamic link library exists, a corresponding prompt can be given. However, in order to implement data interaction between different communication protocols, the present invention may rebuild a corresponding new dynamic link library, that is, if there is no existing dynamic link library of a corresponding communication function module in a pre-specified path, a new dynamic link library is compiled according to a predetermined specification in a factory, and first and second communication protocol information, and the new dynamic link library is stored according to the pre-specified path.
That is, if an undeveloped communication protocol occurs, development and testing are performed on the protocol only according to the specifications agreed in the factory, the protocol is compiled into a dynamic link library to be loaded and called after the development and testing are completed, and then normal data interaction and processing flows are performed. All the operation steps do not relate to the modification and compilation of the existing product codes, and do not influence the original various characteristics of the products.
And 103, respectively constructing an input end communication module and an output end communication module corresponding to the first communication protocol and the second communication protocol by the dynamic link library according to the read parameter point configuration file information, the first communication protocol information and the second communication protocol information.
As shown in table 2 below, in the parameter point profile structure, different columns correspond to different information,
table 2:
| column A | Parameter point indexing |
| Column B | Address of parameter point in first communication protocol |
| Column C | Address of parameter point in second communication protocol |
| Column D | Description of parameter points |
| Column E | Multiplying power of parameter point |
| Column F | Offset of parameter point |
| Column G onwards | Additional information, parsed by a specific communication protocol |
In this step, the parameter point configuration file information is read to obtain an information list of the parameter points, so that the parameter points can be used when an input end communication module and an output end communication module are constructed.
The loaded dynamic link library initializes and constructs the communication module corresponding to each other by reading the information in the communication protocol sub-configuration file (the file path is read from the table 1) and combining the read parameter point information.
And 104, activating a background thread for processing data to package the real-time data acquired by the input end communication module from the data input end, and sending the packaged data to a destination address through the data output end by the data output end communication module.
In this step, the background thread acquires real-time data from the input end communication module in an active request or subscription manner.
In this step, whether to perform secondary processing on the real-time data, for example, whether to perform magnification processing or offset processing, needs to be determined according to parameter information of a specific communication protocol sub-configuration file.
In this step, the real-time data is encapsulated according to the requirement of the data output end communication module on the data format.
When the data communication method based on the factory method mode and the dynamic loading module is adopted, the communication protocol adapted in specific operation is not written in codes but is determined by a main configuration file. If an undeveloped communication protocol appears, development and test are carried out on the protocol only according to the convention specification in a factory, and then the protocol is compiled into a dynamic link library for loading and calling of a software platform, and then normal data interaction and processing flow are carried out. All the operation steps do not relate to the modification and the compilation of the existing product codes, and do not influence the original various characteristics of the products. In addition, the configuration files of the whole software platform are realized in a distributed mode, the main configuration, the parameter point configuration and the communication protocol configuration are stored independently and are responsible for the functions of each user, and the user can modify, maintain, backup and restore the configuration files conveniently.

Specifically, an input protocol Modbus and an output protocol MySQL are obtained by reading information in a master configuration file;
the communication protocol information at the two ends is transmitted to a factory, and the factory searches a dynamic link library (i.e. a plug-in) of Modbus and MySQL communication function modules in a specified path according to the protocol information and loads the dynamic link library to a software platform (at this moment, the existence of the dynamic link library is assumed);
acquiring an information list of the parameter points by reading information in the parameter point configuration file for the communication protocol function modules at the two ends to use;
the Modbus and MySQL dynamic link libraries are used for initializing and constructing respective corresponding communication modules by reading information in respective communication protocol sub-configuration files and combining read parameter point information;
and activating a background thread, periodically executing the Modbus module to read data, performing secondary processing and packaging by the platform, transmitting the data to the MySQL module, and writing the data to a destination address by the MySQL module.
Fig. 3 is a schematic flow chart of a process of implementing a new addition of an Oracle functional module dynamic link library and writing data read by a 104 protocol into an Oracle database by applying the data communication method based on the factory method mode and the dynamic loading module according to the present invention.
The method comprises the following specific steps:
acquiring an input protocol 104 and an output protocol Oracle by reading information in the main configuration file;
the communication protocol information of the two ends is transmitted to a factory, and the factory finds that the dynamic link library does not exist when looking up the Oracle functional module according to the protocol information;
therefore, according to the appointed standard of the read data interface, writing codes aiming at the property of Oracle to realize the corresponding function;
