Abstract: The present application discloses a method and an apparatus for transmitting a message. The method of an embodiment comprises: dividing a shared memory area allocated by an operating system into a plurality of memory blocks for storing messages having different priorities; dividing each memory block in the plurality of memory blocks into at least one memory unit having a successive serial number; determining, from the plurality of memory blocks according to a priority of a to-be-transmitted message, a target memory block for storing the to-be-transmitted message; and writing the to-be-transmitted message into a memory unit of the target memory block. This embodiment implements message transmission based on priorities of the messages, and improves the control security of an intelligent control system.

Abstract: The present application discloses a method and device for establishing communication connection. An embodiment of the method includes: selecting a predetermined number of servers from a server cluster to form a backup server cluster, the server cluster including at least one server adapted to implement a given service; obtaining communication information of each backup server in the backup server cluster, and selecting a backup server from the backup server cluster as a master server based on the communication information of the backup server; and sending the communication information of the master server to controlled equipment controlled by the server cluster to establish communication connection between the master server and the controlled equipment. The embodiment solves a problem of reliability raised when main server abnormally quits or restarts during the operation of a system.

Abstract: The present application discloses a method and apparatus for switching between servers in a server cluster. The server cluster includes at least one server for implementing a given service. A specific implementation of the method includes: detecting a number of servers in a standby state in the server cluster; starting at least one server in the server cluster so that the number of servers in the standby state reaches a predetermined number, in response to detecting the number of servers in the standby state being less than the predetermined number; monitoring a master server for providing a service in the server cluster; and selecting a server from the servers in the standby state as a master server to continue to provide the service, in response to detecting the master server being abnormal. This implementation solves the data loss problem caused by an abnormal termination or restart of the master server.

Abstract: The present application discloses a monitoring method and apparatus. A specific implementation of the method comprises: reading information about monitoring data acquisition methods of monitored objects, the monitoring data acquisition method comprising an active acquisition method and a passive acquisition method; executing following steps for each of the monitored objects having the active acquisition method as the monitoring data acquisition method: generating a monitoring data acquisition task of the monitored object; determining a monitoring data acquisition frequency of the monitored object; and adding the monitoring data acquisition task to to-be-executed monitoring data acquisition task sets in a defined period corresponding to the monitoring data acquisition frequency; executing, in successive defined periods, monitoring data acquisition tasks in the corresponding to-be-executed monitoring data acquisition task sets; and parsing acquired monitoring data of the monitored objects to generate a monitoring result. The implementation solves the problem of high system resource occupation and waste of system resources during the monitoring process.
