Monitoring data acquisition method, device and system

Abstract

The invention provides a monitoring data acquisition method, device and system. The method comprises: receiving the interaction data acquisition signal of a user by a browser, determining the monitoring data needed to be acquired, if the monitoring data is in the preset local storage space, directly acquiring from the local storage space, or sending a data acquisition instruction to a server at appointed time intervals within appointed time, receiving the monitoring data obtained from a monitoring device every time after the server receives the data acquisition instruction, storing the real time monitoring data to the preset local storage space, and obtaining the monitoring data from the preset local storage space. The problems that the data cannot be returned to the browser by the server because of database problem and a great deal of repeated data are stored in the database are solved; the data collection frequency of the server is controlled by the browser, the data are obtained through a plurality of requests, data transmission is more reliable, the monitoring data needed to be obtained are directly read from the local storage space, and the data reading speed is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a monitoring data acquisition method, device and system. Background technique [0002] With the upgrading of browsers and the development of web browser technology, more and more monitoring systems have begun to adopt B / S (Browser / Server, browser / server) mode development, and B / S mode is also because of its Its own irreplaceable advantages are being widely adopted. In the monitoring system, the following processes are usually involved: data collection-data processing-data display. [0003] In modern monitoring systems, since the data collected by monitoring equipment is real-time, and we need to achieve the purpose of storing monitoring data, the usual solution is to store the data collected by the server in the database, and wait for the browser to request Return all the data within a period of time. However, this method has several disadvantages: first, the server ne...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the embodiment of the present invention provides a method, device and system for acquiring monitoring data to solve the problem that in the prior art, the server needs resident tasks to regularly collect data and store it in the database; The database brings a certain amount of pressure, and the requirements for the database are relatively high. There is no need to store the monitoring data that has expired for too long; Part of the transmitted data is repeated, and in order to solve the problem of a large amount of data duplication that may exist, it is necessary to make more modifications to the server processing logic
