Embodiment Construction

[0017] The system includes host computer, gateway, and acquisition system. The host computer and the gateway communicate through 485 bus or LAN or GPRS; embedded in the database.

[0018] The embedded database includes a real-time data processing module and a historical data processing module that communicate with each other. The real-time data processing module includes a real-time resource management unit, a real-time data management unit, a real-time data storage unit, and a PID parameter management unit. The real-time data processing module is connected with the alarm module and the real-time data display module. The real-time data processing module controls the acquisition system through the control circuit, and the acquisition system transmits the collected data to the real-time data processing module through the sensor and the A / D converter. The historical data processing module includes a historical data management unit, a historical data maintenance unit, and a log ...

Abstract

The invention relates to a gateway application system, particularly an embedded real-time data base of a gateway application system. The gateway application system based on an embedded real-time data base comprises an upper computer, a gateway and an acquisition system, wherein the upper computer communicates with the gateway through a 485 bus, or an LAN or GPRS mode; the gateway is connected with the acquisition system through the 485 bus; and the acquisition system analyzes and stores data acquired on site to the built-in embedded data base of the gateway. The system can reliably process the on-site data in real time, efficiently utilize the limited resources of the embedded system, increase the data storage speed and protect the data.

Description

technical field [0001] The invention relates to a gateway application system, in particular to an embedded real-time database of the gateway application system. Background technique [0002] At present, with the development of information technologies such as computers, communications, and networks, information exchange technology has been widely used in factories and enterprises. In modern industrial production sites, a large amount of production data and control data are generated, making the data in the embedded environment Management has become an important part of the industrial control system, which requires that the monitoring software must have powerful data processing capabilities to provide people with real-time and reliable data to reflect the status of on-site operations for corresponding control operations. [0003] The correctness of data in an embedded environment not only depends on the logical results of the data, but also depends on the time when the logica...
