When the main machine fails and cannot normally operate, the standby machine is required to be automatically converted into the main machine within a certain time to replace the original main machine to continue to operate. When the primary and secondary are switched, the operation terminal devices (display, mouse, keyboard, etc.) are switched at the same time, so that the user can operate the new primary machine through the operation terminal devices.

(2) The transmission link between the transmitting end and the receiving end of the double-machine control switcher is an optical fiber, and the distance between the optical fibers is different from 150 meters to 5 kilometers according to different application scenes. The stability of equipment operation is influenced by the transmission quality of optical signals, and a mode of periodic detection at a skylight point is generally adopted to detect the optical fiber light attenuation, and the detection mode needs to stop business to influence the operation efficiency of the equipment.
Other prior art techniques such as: the Chinese patent with the publication number of CN2347205Y entitled "Dual-machine controller of multimedia terminal" has the technical problems described above in the Chinese patent with the publication number of CN101648570B entitled "Dual-machine Hot standby switch and Dual-machine Hot standby switching method".
