Problems solved by technology

[0003] However, different projects may use different monitoring systems due to different requirements, and different monitoring systems provide different in-memory databases, so the dedicated interfaces provided are also different.
Therefore, in the process of secondary development, it is necessary to use the memory data interaction tools of the monitoring system software, which causes inconvenience for technicians in secondary development and debugging.

Abstract

The invention discloses a monitor system memory database universal interactive method which has characteristic in including steps as follows: 1) defining a similar SQL language, inputting needed similar SQL sentence; 2) translating the input similar SQL sentence into an object code; 3) executing the object code generated by translating and calling an interface special for the memory database for processing interacting. The method uses uniform similar SQL sentence for processing interacting with various maker memory database that is suitable for various UNIX operation system, LINUX operation system and WINDOWS operation system, has strong commonality; in additional, all functions are realized in an application layer and need not get help to any operation system software itself.

Description

technical field [0001] The invention relates to a general interaction method for a memory database of a monitoring system, belonging to the technical field of computer system control. Background technique [0002] The data monitored by the monitoring system in the real-time control field changes very quickly. For example, in the power grid monitoring system, it is often necessary to refresh thousands or even tens of thousands of analog and digital quantities within a few seconds. The monitoring system in the industrial control field also has the same demand. For example, if a factory with 10,000 points changes once every two seconds, 5,000 points will change every second, so the monitoring system in the field of power system and industrial control will use the special memory belonging to this system Database, generally speaking, the memory database will use two-dimensional tables to store data and provide a dedicated interface. Technicians use the monitoring system software...
