Problems solved by technology

But this technology is relatively new, and almost all SIS systems do not have this function yet
[0023] , Like the real-time database of the DCS system, it is difficult to release the storage space occupied by the waste points in the SIS system

Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0065] Such as figure 1 , 2 As shown, a new time-series data storage method for power plants includes the following steps:

[0066] S01: Use the interface function of DCS system or SIS system to collect real-time data from the DCS system database or SIS system database; the interface function can be API interface function or OPC interface function, and multiple programs can be started at the same time to collect real-ti...

Abstract

The invention discloses a new time sequence data storage method applied to a power plant. The method comprises the steps that an interface function of a DCS (distribution control system) or an SIS (supervisor information system) is utilized to collect real-time data from a DCS database or an SIS database; first compression is performed on the collected real-time data; the collected data is saved in the form of text files, the text files are stored on a directory A of a local hard disk, one measurement point corresponds to one file, and each file saves the data at a first certain time; the filein the last time period is sent to data receiving equipment outside a gateway, and the file is deleted after transmission is completed; received data is saved in the local hard disk, one measurementpoint corresponds to one file, and each file saves the data at a second certain time; and second compression is performed on the file data through compression software, and a compressed file is obtained. Through the method, historical data can be collected quickly and efficiently, the collected data has high integrity, the compression rate is high, and data reading speed is high.

Description

technical field [0001] The invention belongs to the technical field of historical data collection of DCS systems or SIS systems of power plants, and in particular relates to a new storage method for time series data of DCS systems or SIS systems of power plants. Background technique [0002] All thermal power plants now have a distributed control system (Distribute Control System, DCS system) and a plant-level monitoring information system (Supervisor Information System, SIS system). The DCS system is mainly responsible for monitoring and controlling the relevant parameters of tens of thousands of valves, switches, pumps, fans, steam turbines, boilers, generators and other equipment in the whole plant. The SIS system is mainly used for remote monitoring of production flow charts and analysis of production data , The main difference between the SIS system and the DCS system is that the SIS system can only monitor but not control field devices. The DCS system and the SIS syst...
