Problems solved by technology

[0018] The performance of these real-time databases is of course outstanding, but their prices are also very expensive, usually in millions of RMB
For SIS / MIS projects implemented in power plants, if these real-time databases are used, they are not completely suitable for the operation of power plant enterprises, and other application modules must be added, and the cost is self-evident

Embodiment Construction

[0060] 1. SyncBASE real-time database operating environment

[0061] (1) Operating system: Windows 95 / 98 / ME / NT4 / 2000 / XP; Windows NT4.0 or higher is recommended.

[0062] (2) Minimum configuration: CPU: Pentium 166MHz; memory: 64MB; graphics card: VGA, 256 colors, hard disk: 5M

[0063] (3) Recommended configuration: The user must consider the number of data collection points of the server and the maximum number of clients connected to the server at the same time to determine the configuration of the server. If the number of clients connecting to the server at the same time is different from the recommendations below, please adjust the memory size of the server. For PentiumII 500MHz PC, the recommended configuration is as follows.

[0064] (4) Database: The operation of the SyncBASE real-time database requires the support of a general relational database. In theory, any database system that supports standard ODBC or OLE DB interfaces can be used.

Abstract

The invention discloses a real-time gathered database system setting method of fossil-fired power plant based on Sync BASE setting method, which is characterized by the following: transmitting the real-time or historic data of control system into universal database format; compressing the data; storing the gathered data, time interval and precision of control system at basic pattern; storing the real-time data and historic data through special file; adapting the driving program of control system to store the gathered data in the universal communication Sync BASE through multiple interface connecting the control system. The invention integrates data gathering, data compressing and product dynamic scanning function into entire real-time database system, which satisfies the need of data gathering speed and memory capacity.

Description

1. Technical field [0001] The invention relates to a setting method of a real-time database system software (SyncBASE), in particular to a setting method of a real-time database system for saving and analyzing a large amount of real-time data in the production process of a thermal power plant. 2. Technical Background [0002] With the rapid development of computer and network communication technology, DCS distributed control system and auxiliary control system PLC are generally used in large power plants to improve the automation level of units. However, each control system, control system and plant-level management information system (MIS) are often isolated from each other, becoming information islands, and information sharing cannot be achieved within the entire plant, resulting in a great waste of information resources. The Supervisory Information System (SIS for short) of the thermal power plant came into being under such circumstances. [0003] The SIS system is an in...
