Embodiment Construction

[0035] In order to make the measures, creative features, goals and effects achieved by the technology of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0036] figure 1 It is a structural schematic diagram of an active monitoring system for cluster equipment in the earthquake industry.

[0037] like figure 1 As shown, an active monitoring system for cluster equipment in the earthquake industry includes: a central monitoring system 1 and a cluster 2; the cluster 2 includes a plurality of cluster nodes, and each cluster node is connected to the central monitoring system through a communication link.

[0038] In this embodiment, the central monitoring system adopts a Linux server, installs Cacti open source network management software in the Linux server, and sets a polling cycle in the Cacti open source network management software, and monitors the cluster nodes.

[0039]In this embod...

Abstract

The invention belongs to the technical field of cluster node monitoring, and provides an earthquake industry cluster equipment active monitoring system and a polling mechanism. The system comprises a central monitoring system and a cluster. The cluster comprises multiple cluster nodes. Each cluster node is connected with the central monitoring system via a communication link. The cluster nodes in the cluster are divided into two queues, and the polling sequence of each node in the queues is dynamical allocated step by step according to priority; a dynamic queue priority threshold value is set; each node of the static queue has equal status; in one polling period, polling is performed by the central monitoring system according to node priority, and node priority is reduced after polling; polling of the static queue is performed if polling is completed; and if one time polling of the dynamic queue is not completed within polling time, polling directly ends. Earthquake monitoring waveform and other information are ensured to be accurately and timely acquired when an earthquake comes so that earthquake disaster influence can be reduced to the largest extent, and communication link guarantee can be provided to earthquake monitoring data transmission.

Description

technical field [0001] The invention belongs to the technical field of cluster node monitoring, in particular to an active monitoring system for cluster equipment in the earthquake industry and a cluster node monitoring polling mechanism based on a dynamic priority queue. Background technique [0002] Seismic departments of all provinces and cities across the country have deployed earthquake monitoring equipment in their respective jurisdictions, including data collectors, geoelectric observers, geomagnetic observers, servers, routers, etc. These devices communicate with the central server through different links to form a large cluster , the operation and maintenance of each node equipment in the cluster has become an extremely important part of the earthquake monitoring business, and whether the equipment status is normal or not determines whether the earthquake monitoring data can be transmitted to the center in a normal, timely and accurate manner for earthquake analysis,...
