Problems solved by technology

However, in the active-standby redundant mode, all controlled units or controlled devices controlled by the main server or the main controller need to obtain communication from the main server or the main controller before establishing communication with the main server or the main controller The required parameters, the main server or the main controller are very important in the whole control system, once the main server or the main controller crashes, it will cause the whole control system to crash, make the system out of control, and the safety and stability of the system cannot be guaranteed
The method of restarting the server or controller that exits abnormally will cause the data loss of the main server or controller and the controlled device after the system exits abnormally, causing the system to fail to work normally after restarting

Abstract

The application discloses a webpage generating method and device. A specific implementation way of the method is as follows: selecting servers with predetermined number from a server cluster to generate a standby server cluster, wherein the server cluster comprises at least one server for realizing the same service; acquiring information for communication of each standby server in the standby server cluster, and selecting one standby server from the standby server cluster as the main server according to the information for communication of the standby server; sending the information for communication of the main server to controlled equipment accepting the control of the server cluster, thereby establishing the communication connection between the main server and the controlled equipment.Through the implementation way disclosed in the invention, the reliability problem caused by the abnormal exit or restarting of the main sever in the system running process is solved.

Description

technical field [0001] This application relates to the field of computer technology, specifically to the field of Internet technology, especially to a method for establishing a communication connection, Background technique [0002] At present, multiple servers or controllers are configured in a control system that requires high security and stability. Most servers or controllers in the system adopt active and standby redundancy, or restart servers or controllers that exit abnormally. The way to solve the security and stability of the system. However, in the active-standby redundant mode, all controlled units or controlled devices controlled by the main server or the main controller need to obtain communication from the main server or the main controller before establishing communication with the main server or the main controller The required parameters, the main server or the main controller are very important in the whole control system, once the main server or the main ...
