Intelligent power distribution terminal communication weak coupling modularized system and method

Abstract

The invention discloses an intelligent power distribution terminal communication weak coupling modularized system and method. The system comprises that: different types of protocol programs are integrated in a protocol dynamic library; a communication management main system provides an interface for loading the protocol programs in the protocol dynamic library; the communication management main system starts independent threads according to the loaded protocol programs, binds the threads with the loaded protocol programs, organizes data into the data types demanded by protocols and transmits to various different protocols; and the protocol dynamic library processes the messages issued by the communication management main system or submitted by a client, obtains useful data information, stores in corresponding caches and issues or submits to other application programs according to standard protocol types and packaging formats in the protocols. The system and the method of the invention has the advantages that the program modularization is high; the functions of each module are mutually independent; the portability and expansibility of the programs are good; starting and stopping of the protocol library can be controlled freely; the system cost is low; and the errors of the protocol programs can be positioned more accurately.

Description

Technical field [0001] The invention relates to the technical field of intelligent power distribution terminal communication, in particular to a weakly coupled modular system and method for intelligent power distribution terminal communication. Background technique [0002] The intelligent power distribution terminal communication system sends and receives messages according to the configuration protocol on the communication port. The protocol configuration includes CDT, 101, 103, 104, Modbus and other protocols. Each protocol needs to organize and analyze the sent and received messages , Store the data in the communication management main program, and then the main program provides an interface to obtain the data, and then distribute the data to other applications. The entire process is tightly coupled. [0003] This design method makes the interface between the different components of the application closely connected with its function and structure. Therefore, when changes occur...

Problems solved by technology

[0003] This design method makes the interface between different components of the application closely connected with its function and structure, so when a change occurs, the adjustment of a certain part will cause changes in other parts or even the entire application along with various strong coupling relationships. Changes that make the architecture of the entire system fragile
