Example Embodiment
[0023] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0024] The heartbeat detection method and optimization strategy under the SCADA distributed platform of the present invention mainly include four parts.
[0025] 1. Heartbeat thread design
[0026] Design a heartbeat detection service process for each node in the SCADA distributed system (including active and standby servers, and active and standby workstations), and establish two threads in the heartbeat detection service process to implement the heartbeat detection mechanism, such as figure 1 As shown, the schematic diagram of the heartbeat detection mechanism.
[0027] Heartbeat sending thread A:
[0028] This thread is used to send heartbeat packets to the target node server every 5 seconds. Before sending, first judge whether the maximum number of heartbeat loss of this node for the target node is greater than 3, if yes, then judge that the target nod...
