Abstract

The invention discloses a control system. The control system comprises control equipment, communication interface equipment, execution equipment, a first channel, a second channel, a third channel, afourth channel, a fifth channel and a sixth channel, wherein the execution equipment comprises a first execution unit and a second execution unit, and the first channel is connected with the control equipment and the communication interface equipment separately; the second channel is connected with the control equipment and the communication interface equipment separately; the third channel is connected with the control equipment and the communication interface equipment separately; the fourth channel is connected with the control equipment and the communication interface equipment separately;the fifth channel is connected with the communication interface equipment, the first execution unit and the second execution unit separately; and the sixth channel is connected with the communicationinterface equipment, the first execution unit and the second execution unit separately.

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...
