The invention provides a control method, device and system based on a non-similar redundancy technology. The method comprises the steps that: a control system is established, wherein a control center is connected with a controlled device through control links, and the control link comprises at least two data communication modes; and the control center sets a priority sequence table of each control link under different working conditions according to a data communication mode, selects a working mode, selects an available control link according to the priority sequence table of the control links, configures a corresponding working environment, controls the controlled device by using the selected available control link, determines whether the available control link between the control center and the controlled device is normal or not, determines the normal operation of a system if the available control link is normal, determines whether a redundant control link exists between the control center and the controlled device if the available control link is abnormal, determines system faults if the redundant control link does not exist, executes alarm operation, and returns to the operation of selecting the available control link according to the priority sequence table of the control links and configuring the corresponding working environment if the available control link exists.
Description
technical field [0001] The invention relates to the technical field of system control, in particular to a control method, device and system based on non-similar redundancy technology. Background technique [0002] Control systems have been widely used in various fields of human society.
