Data acquisition system and method

Abstract

The invention provides a data acquisition system and method. According to the data acquisition system and method, data acquisition and configuration are achieved in a BS mode, a user can access data under the condition that the user communicates with a server network, the problem of independent faults is avoided, read-write separation is achieved, and the pressure of a main node is reduced. Meanwhile, the system also supports the acquisition of universal protocols and various statistical reports, and can meet the demands of more customers.

Description

technical field [0001] The invention relates to the field of industrial control systems, in particular to a data acquisition system and method. Background technique [0002] Energy infrastructures such as power grids are often driven by multilevel control systems that observe system states and respond to achieve local stable operating points. The integration of networked control systems with other networks makes them vulnerable to various sabotages, malicious attacks, and cyber threats. For example, electric utilities often use communications networks and software applications to keep power generation in line with demand. However, communication networks and software applications are vulnerable to cyber attacks, and attackers have proven capable of disabling critical controllers and causing highly disruptive power outages. Prolonged failures of critical systems in power grids, water / wastewater, public health, transportation, banking, and industry can halt economic activity,...

Problems solved by technology

However, most of the existing systems are based on the C / S (Client-Server) architecture. Although the processing capacity of the client computer can be fully utilized, many tasks can be submitted to the server after the client processes, so the client responds quickly, but it needs The dedicated client installation program has weak distribution functions. It is aimed at user groups with many sites and wide areas and no network conditions. It cannot achieve rapid deployment, installation and configuration. The development and maintenance costs are high, and technical personnel with a certain professional level are required to complete. , an upgrade occurs, all client programs need to be changed

[0003] Moreover, all real-time data in the existing system is stored in the same database and data table. Once there are many points, there will be a large amount of data reading and writing. At this time, the real-time data refresh of the page will be delayed for a long time.

At the same time, due to the limited configuration functions, the report and analysis functions realized are very limited, sometimes unable to meet the needs of customers
