Abstract

The invention discloses a redundant circuit and a redundancy conversing method. The redundant circuit comprises a spare module, a working module, a base, a redundancy diagnosis circuit and a controller, wherein the spare module and the working module are connected with the base through a hot plug interface; the redundancy diagnosis circuit is respectively used for detecting the connection of the spare module, the working module and the base; when being not reliably connected with the base, the spare module keeps a spare state and interrupts data transmission with the outside; when the spare module is reliably connected with the base and a communication bus is not provided with the working module, the spare module automatically converts to a working state; and when the spare module is reliably connected with the base and the communication bus is provided with the working module, the spare module keeps a spare state and interrupts the data transmission with the outside. Therefore, even through the spare module is poor in contact at the moment of plugging, the spare module can not respectively communicate with the communication bus and the working module, thus the working module can safely and regularly work.

Description

Technical field [0001] This application relates to the technical field of industrial control, and in particular to a redundant circuit and a redundant switching method. Background technique [0002] The 1:1 hot standby redundancy technology is widely used in industrial control systems. The 1:1 hot standby redundancy technology refers to the installation of two identical components, and the two identical components are in the control state and the standby state respectively. In the control system When a component in the control state fails during operation, its spare component will take over the work of the faulty card instantly and without disturbance, ensuring the continuous and correct operation of the entire control system. Existing industrial systems use redundant voting technology and redundant communication technology to achieve reliable automatic failover functions, but the pedestal-based 1:1 hot-standby redundant module often has problems during the hot-plugging process o...
