Description

technical field [0001] The invention relates to a control system, in particular to a control system capable of ensuring reliable transmission of control commands and data. Background technique [0002] In practice, in order to improve the data transmission reliability of the control system or communication system, dual-system hot standby system or dual-system hot standby machine technology is usually used. In the dual-system hot standby system, the communication interface equipment is divided into the main machine and the standby machine. Under normal circumstances, the main machine is in the working state, and the standby machine is in the hot standby state. When the main machine fails, the standby machine switches to the main machine to work. This solution requires synchronization and real-time communication between the main machine and the standby machine. If the main machine functions abnormally and sends heartbeat frames normally, the standby machine cannot know the cur...
