description The invention discloses a redundancy switching system. The redundancy switching system is used for main/standby switching between a server A and a server B, and comprises a man-machine interface module, a switching control module, a communication interface switching module and a power supply module, wherein the man-machine interface module is used for selecting the main/standby switching mode, and indicating the current main/standby switching state and the operation state of main/standby servers; the switching control module is used for acquiring the main/standby switching state of the man-machine interface module, and acquiring the control command and the operation state of the server A and the server B through a control interface; the switching control module decides which one is the main server and which one is the standby server among the server A and the server B through logic switching; and the communication interface switching module switches an external communication interface to a determined server according to the control command of the switching control module. The redundancy switching system can realize data synchronization and main/standby switching required by redundancy through the hardware circuit, and has the advantages of being stable and reliable, being smooth and reliable in switching, and being able to reduce the time varying and uncertain risks brought by switching of software.
