[0002] There are many devices in the high-speed wire rolling line area of a rolling mill, and the communication between the direct current transmission systems is relatively perfect, and the information exchange and command transmission are relatively smooth. However, the finishing transmission system and the finishing control subsystem, the DP coupling control system and the rolling line control center are in a non-communication state, which causes that the information, signals and commands between the whole finishing transmission system and the DP coupling control system cannot be transmitted, the information, signals and commands between the whole DP coupling control system and the rolling line control center cannot be transmitted, and the information, signals and commands between the whole finishing comprehensive transmission system and the rolling line control center cannot be transmitted.

[0003] Due to the above factors, in the prior art, there is a serious mismatch between the actual needs in the production process and the information, state and command needs of the device operation. When a single independent subsystem appears a pre-warning information or an instructive cross-area driving, the prior art cannot realize information transmission and command driving, and thus cannot complete the normal transmission and operation of the device state information and the connecting driving command, and cannot realize the information transmission and driving execution between the cross-stands in the normal rolling process, which causes the amplification of hidden danger state, causes accidents and steel stacking, and has great defects in supporting the lean production and the long-period safe and stable operation of the device. Therefore, the present application proposes a communication control system and method for three symmetrical ring states and functions of a high-speed wire rolling line to solve the problems in the prior art.
