Control implementing method and system

Abstract

The invention discloses an industrial process control method and a system, wherein the method comprises the following steps: a read-write operation request is generated; a thread is allocated aiming at the read-write operation request, and the thread is maintained until the read-write operation request is finished; the step generating the read-write operation request and the step allocating and executing the thread are completed in an application process; a preset mapping relation list is found, and a required read-write function aiming at corresponding bottom hardware is obtained; the mapping relation list is used for storing the mapping relation between the read-write operation request and the specific read-write function; the read-write function is executed, a driver of the bottom hardware is transferred to complete the corresponding operation, required result data can be obtained, and the thread is finished. The invention can improve the communication efficiency between the bottomhardware and a data acquisition part in the industrial process control system.

Description

technical field [0001] The technical field of industrial process automation of the present invention particularly relates to a method and system for industrial process control. Background technique [0002] Industrial control automation technology is a kind of use of control theory, instrumentation, computer and other information technology to realize detection, control, optimization, scheduling, management and decision-making of industrial production process, so as to increase production, improve quality, reduce consumption, ensure safety, etc. The comprehensive technology of the purpose mainly includes three parts of industrial automation software, hardware and system. As one of the most important technologies in the modern manufacturing field in the 20th century, industrial control automation technology mainly solves the problems of production efficiency and consistency. [0003] In the entire automation technology, industrial control software is a force that cannot be i...

Problems solved by technology

[0006] 1. Since Socket communication is used between two processes, Socket communication itself has the following disadvantages:

[0007] 1) The connection must be established to communicate, and the connection will take a certain period of time;

[0008] 2) It is not suitable for single-point to infinite multi-point communication;

[0009] 3) Not suitable for unfixed multipoint-to-multipoint communication;

[0010] 4) Ordinary Socket is not encrypted during the communication process (UDP is also);

[0011] 5) Socket connections cannot be shared in child processes;

[0012] 6) Both sides of the connection must have relatively fixed IP addresses;

[0013] Moreover, Socket communication is based on TCP / IP network communication protocol, so the data transmission speed is relatively slow
