Triple redundant control method and system

Abstract

The invention provides a three-redundancy control method and system. The system includes large-scale equipment and three controllers connected to the large-scale equipment. The invention uses three controllers to perform data interaction with large-scale key equipment. The three controllers The same collected data is processed, and the three controllers vote on the collected data of the three controllers through triple-redundant communication, and the voting data is fed back to large-scale key equipment. When a controller with high fault tolerance is selected, the probability of failure of one controller will be reduced, and the probability of failure of three controllers at the same time will be even lower. The probability of failure of large-scale key equipment is reduced, and the customer's increasing requirements for large-scale key equipment are met.

Description

technical field [0001] The invention relates to the field of industrial triple redundancy, in particular to a triple redundancy control method and system. Background technique [0002] Some key equipment in the industrial field needs to run for a long time and with high load, especially in some key areas, such as large-scale key equipment such as large-scale power station steam turbine generator sets, large-scale boilers, etc., large-scale key equipment is usually controlled by the controller, these The normal operation of important equipment is directly related to the major interests of the company and customers, so a controller with high fault tolerance is required to control these large industrial key equipment. Fault tolerance means the maximum error that the controller is allowed to accept during normal operation, that is, although there are some errors, the controller can still operate normally and produce the expected results. [0003] However, in the prior art, ther...

Fault tolerance indicates the maximum error that the controller is allowed to accept during normal operation, that is, although there are some errors, the controller can still operate normally and produce the expected results

[0003] However, in the prior art, there is generally only one controller for controlling large-scale key equipment, that is, a single controller. No matter how high the fault tolerance capability of the single controller is, it will also cause problems beyond single-mode control due to internal component damage or disrepair. The failure of the fault tolerance makes it impossible for a single controller to control large-scale key equipment, which in turn leads to failure of large-scale key equipment. However, the control of large-scale key equipment is not allowed to fail as much as possible. It has been unable to meet the increasing requirements of customers for large-scale key equipment
