METHOD FOR FORMING A DATA TRANSMISSION NETWORK OF AN AUTOMATED PROCESS CONTROL SYSTEM Russian patent published in 2022 - IPC G06F15/16 H04L41/00 

FIELD: communication.

SUBSTANCE: invention relates to a method for forming a data transmission network of an automated process control system. In the method, network cells are formed from modules so that, for each network cell: modules with identical hardware, made of at least two different types corresponding to the roles of the modules and determined by the functions of the modules in the network, are added to the network cell; the modules are interconnected with communication channels established between said channels for data exchange, wherein each module is connected to all other modules via at least one communication channel or another module; each of the modules is configured, setting the type of module depending on the role of the module corresponding to the functional task of each module, by loading software into the memory of the modules depending on the required functions, wherein the tasks are distributed among the modules at least to ensure that the amount of data transmitted over the communication channels is minimised, and the distribution of tasks includes calculating the amount of data transmitted by each module and each sensor linked with the module, each operating cycle of the module, equal to the frequency of data reception from the object of control linked with the module, and a task is selected for each module, such as to define the type of module, so that the data transmission over each of the communication channels is minimal, so that the operation of a module of the second type depends partly on the data transmitted by the sensors of the objects of control linked with the module of the second type; depends partly on the data transmitted by the module of the first type to the module of the second type; partly does not depend on the data transmitted by the module of the first type to the module of the second type, and partly does not depend on the data transmitted by the sensors linked with the module of the second type, so that the execution of one part of the task by a module of the second type depends on the task executed by a module of the first type, the execution of the other part of the task by a module of the second type does not depend on the task executed by a module of the first type, and the task executed by a module of the first type does not depend on the task executed by a module of the second type; the formed network cells are interconnected via communication channels, forming a multiprocessor computing cluster with a structure determined by the composition and interrelations of the executed tasks, wherein each of the communication cells is linked with at least one other communication cell via a communication channel, so that each of the modules in each communication cell is the central processing unit and simultaneously the I/O module of that module, and simultaneously a remote I/O module for at least one other module, so that the module performs the functions of both the central processing unit and the I/O module for both that module and at least one other module, wherein a module of the first type is an I/O module for a module of the second type, and a network cell is an input module for at least one other network cell and/or is an I/O module for at least one other network cell, and wherein a separate processor is allocated for each task.

EFFECT: higher effectiveness of using network resources and sharing data between network apparatus.
