Function block control method of automatic control system

Abstract

The invention belongs to the network communication technology field and provides a function block control method of an automatic control system. The function block control method is characterized in that: a control program of a whole set of the automatic control system is divided into several function program subblocks (3); the several function program subblocks (3) are respectively arranged corresponding to one function or one control element which are controlled by the function program subblocks; the each function program subblock is used to independently process all signal related to the function of the function program subblock and receives all commands of a main control program block (1) which is related to the function of the function program subblock; the main control program block (1) is used to control an operation sequence of the several function program subblocks and is mutually communicated with a main database; subdatabases (4) which are related to the function of the function program subblocks are arranged in order to correspond to the several function program subblocks. By using the method of the invention, a plurality of tasks which do not interfere with each other can operate simultaneously so that an operation efficiency can be increased. When the one-to-one function program subblocks and the databases appear confusion, overhauling with a purpose can be performed and artificial maintenance costs are low.

Description

Technical field [0001] The invention is the field of network communication technology, and it mainly proposes a functional block control method for automated control systems. Background technique [0002] A automated control system contains dozens or even hundreds of functions, and the corresponding functions have multiple functional programs; and the entire program is controlled by a program block or a small number of program blocks that cannot work independently.The automated control system in existing technologies generally use centralized control, such as figure 1 Show, all functional programs of an automated control system, such as the control of all oil cylinders, the control of the motor, the oil pump control and other program functions are attributed to the same main program control block, and the same main program control block controls all the actions of all functional programs.All functional programs can only rely on the main program control block. Such a control is v...
