Problems solved by technology

The automation control system in the prior art generally adopts centralized control, such as As shown in Figure 1, all functional programs of an automatic control system, such as the control of all oil cylinders, motor control, oil pump control and other program functions, belong to the same main program control block, and are controlled by the same main program control block. All actions of the functional program, all functional programs can only depend on the main program control block, such control is very prone to repeated programming and repeated execution of a certain job; in addition, when programming the centralized control automation control system, due to all Functional programs are all under the control of the main program, so that the data of all functional programs belong to the main database. When an abnormality occurs in a certain functional program, it is difficult to troubleshoot; and it is impossible for multiple people to coordinate programming to speed up the programming; the above reasons will cause Low operating efficiency and high labor maintenance costs

Embodiment Construction

[0011] The present invention is described in conjunction with accompanying drawing and specific embodiment;

[0012] Such as figure 2 As shown, a function block control method of an automation control system, the function block control method is: the control program of a whole set of automation control system is divided into several function program sub-blocks 3, and the several function blocks 3 are Program sub-blocks 3 correspond to a certain function controlled or a certain control element setting respectively, such as dividing the automatic control program of a large-scale equipment into: transmission motor speed function program sub-block, transmission motor torque function program sub-block, Main control program block 1, hydraulic system pump station function program sub-block, hydraulic system oil cylinder action function program sub-block and emergency state control function program sub-block and other functional program sub-blocks 3; used to independently process all...

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...
