Redundant-waste heat backup method of mater engine in centralized control system

Abstract

The invention provides a redundant-waste heat backup method of a mater engine in a centralized control system, belongs to the field of centralized control, and in particular relates to a redundant-waste heat backup method of a mater engine in a centralized control system. The method comprises the steps that redundant-waste heat backup of the master engine is conducted in operating terminal starting process and the redundant-waste heat backup of the master engine is conducted in operating terminal control instruction sending process; it is ensured that the operating terminal is connected to a control master engine in the centralized control system reliably, and it is ensured that each instruction can sent to the master engine in the operating terminal control instruction sending process; the problem is solved that the whole centralized control system cannot work under the circumstances such as the master engine is crashed or the connection is broken due to that the operating terminal cannot be connected to the master engine, and the instruction cannot be sent to the master engine, so that the controlled equipment is out of control considering that the current centralized control system only comprises one control master engine.

Description

technical field [0001] The invention relates to the field of centralized control, in particular to a redundant hot backup method for a host computer in a centralized control system. Background technique [0002] The centralized control system refers to a system that uses computer communication technology to intelligently control and manage the controlled equipment. It uses this system to centrally control and manage the controlled equipment that was originally controlled and managed in a decentralized manner. At present, in the field of centralized control systems, there is often only one centralized control host connected to each controlled device. Once the centralized control host fails, the entire centralized control system cannot work, and it takes time to repair the centralized control host. Reduced availability and reliability of the entire system. [0003] However, in the existing centralized control system, the sending ports of some instructions are fixed on the con...

AI Technical Summary

Problems solved by technology

At present, in the field of centralized control systems, there is often only one centralized control host connected to each controlled device. Once the centralized control host fails, the entire centralized control system cannot work, and it takes time to repair the centralized control host. Reduced overall system availability and reliability

[0003] However, in the existing centralized control system, the sending ports of some instructions are fixed on the control host, and the control host and the controlled equipment are connected through a dedicated cable, and then the instructions are transmitted from the control host to the controlled equipment through this dedicated cable. Therefore, it is impossible to realize redundant hot backup in this architecture. Even if the user perceives that the connection between the controlled device and the control host is lost, the cable reconnection between the controlled device and the host must be manually intervened. to achieve
