Problems solved by technology

[0005] Although the above patents all disclose distributed control systems for practical applications, they can only be used for fixed information applications, and the application field is too narrow. At the same time, due to the lack of "error correction unit", the stability of the entire distributed system not enough

Embodiment Construction

[0031] figure 1 It is a structural block diagram of the first embodiment of the distributed open-loop automatic control system using electronic communication equipment in the present invention. The system includes a plurality of main control modules 1 connected through the basic network (the number of specific settings is determined according to needs), a storage module 2 corresponding to each main control module 1 with two-way data connection, and each main control module 1 One-to-one corresponds to the connected controlled components 3, an information identification transmission module 4, an information sending and receiving module 5 and a plurality of electronic communication devices 6 (the specific number of settings is determined according to the needs). Among them, the multiple main control modules 1 have no subordinate relationship with each other, and they can be directly connected to each other, or can obtain an indirect connection relationship through other main cont...

Abstract

The invention discloses a distributed loop-opening automatic control system utilizing electronic communication equipment. The system comprises the electronic communication equipment, a message receiving and dispatching module, a message identification and transmission module, a main control module connected with a substrate network and a storage module for storing a control program sequence, wherein the electronic communication equipment sends a control instruction to the message receiving and dispatching module; the message receiving and dispatching module receives the control instruction and sends the control instruction to the message identification and transmission module; the message identification and transmission module receives the control instruction, identifies the control instruction, and sends the identified control instruction to the main control module; and the main control module receives the identified control instruction, extracts the control program sequence matched with the control instruction from the storage module according to the identified control instruction, and controls the operation of a controlled element according to the control program sequence. The invention also discloses a distributed loop-opening automatic control method utilizing the electronic communication equipment. The system and the method can be widely applied to different industrial control fields and have precise control and good working stability.

Description

technical field [0001] The invention relates to a control system applied in the field of industrial control, in particular to a distributed open-loop automatic control system and method using electronic communication equipment. Background technique [0002] Today, with the rapid development of digital equipment, in order to meet the increasing amount of data that various systems need to process, the system control is becoming more and more complex, and the ability of each component or part to work together between the systems is getting stronger and better, and the real-time performance is getting better and better. , stronger stability, and lower and lower failure rates, people have developed different control systems. Control systems can be mainly divided into centralized control systems and distributed control systems. Each of these categories can also be subdivided into manual control systems and automatic control systems, open-loop control systems and closed-loop contr...
