Problems solved by technology
[0003] At present, real-time wave recording data generally adopts a one-way collection and forwarding method. The front-end service has become the bottleneck of the load capacity of the monitoring system. In terms of load capacity and load capacity, it cannot meet the monitoring needs of the vibration and swing device of the current hydroelectric unit
Moreover, the screen operation of the operation and maintenance personnel is random, and the monitored devices need to be adjusted in time. However, unicast (one-way collection) is not efficient compared to multicast in terms of multi-machine data requests, and it will also lead to unstable network traffic fluctuations. Indirectly affect the synchronization effect of screen controls

The present invention discloses a dynamic real-time recording monitoring method. According to the method disclosed by the present invention, an address of a hydroelectric unit vibration device is mapped into a multicast address, all hydroelectric unit vibration devices that will be associated with the screen configuration is monitored, a multicast group corresponding to the hydroelectric unit vibration device is entered, a multi-host differentiated recording request is provided by using a multicast protocol, and time scale alignment is carried out through the time stamp of the sampling time of real-time recording data, so that synchronous refresh of screen controls is realized, the network throughput is reduced, and the monitoring system load capacity is improved; and dynamic switch of the monitored objects is realized according to the screen configuration associated hydropower unit vibration device, so that concurrency of monitoring system multi-host data processing is increased while the timeliness is improved, and the good application prospect is ensured.
Description
technical field [0001] The invention relates to the technical field of electric power system smart grid monitoring, in particular to a dynamic real-time wave recording monitoring method. Background technique [0002] With the increasing monitoring methods and detection efforts, the conventionally collected data such as telemetry and remote signaling for hydropower units is no longer sufficient to meet the needs of operation and maintenance. Diversified and multi-dimensional displays such as real-time curves, axis trajectories, and space trajectories have become hydropower units. A must-have function for a runout monitoring system. Real-time wave recording data has the characteristics of high density, high throughput, and low quality. However, the existing substation data collection is a shared private network channel, and the collection of real-time wave recording data will increase the network load pressure. At the same time, the multi-machine screen differentiation Data r...
