Power control terminal establishing method based on embedded system

Abstract

The invention discloses a power control terminal establishing method based on an embedded system. The method comprises the following steps of 1) fusion analysis and general framework design; 2) designand realization of a fusion file management module; 3) design and realization of buffer memory management fusion, and design of buffer memory fusion; and 4) and research on a dynamic multi-granularity blocking mechanism based on an affair off period. According to the method, application of the embedded system in the power control field is combined, redundancy functions of an embedded database andthe embedded operating system are analyzed, and fusion of the embedded database and the embedded operating system is researched and designed.

Description

technical field [0001] The invention relates to a method for building a power control terminal based on an embedded system, and belongs to the technical field of computer software and hardware design. Background technique [0002] The application of embedded systems in power systems has a long history and is widely used in instrument detection, distributed control (DCS), data acquisition, automatic devices and other fields; among them, the more typical applications are in data acquisition and monitoring, microcomputer protection, Equipment control and energy billing, etc.; there is a large amount of data in the power system, and with the increase of power control equipment, the data to be processed will inevitably increase sharply; if only relying on the database management system of the dispatching center for processing, It will inevitably increase the task of the dispatching center, and if each terminal transmits data to the master station, and then waits for the master st...

[0002] The application of embedded systems in power systems has a long history and is widely used in instrument detection, distributed control (DCS), data acquisition, automatic devices and other fields; among them, the more typical applications are in data acquisition and monitoring, microcomputer protection, Equipment control and energy billing, etc.; there is a large amount of data in the power system, and with the increase of power control equipment, the data to be processed will inevitably increase sharply; if only relying on the database management system of the dispatching center for processing, It will inevitably increase the task of the dispatching center, and if each terminal transmits data to the master station, and then waits for the master station's order, it will inevitably greatly reduce the real-time performance of the system; However, the amount of data and information in the power system is not only huge, but also changing rapidly. In order to better control the operation of the system, monitoring personnel need to obtain relevant information in real time, and make correct judgments based on these information, and take corresponding measures. measures; these applications have different characteristics from traditional applications. On the one hand, they need to process a large amount of data. On the other hand, their application activities (transactions) have a strong timeliness, that is, they require The transaction is processed; and the transaction is often time-sensitive; therefore, this application requires both the functions and characteristics of the database and real-time processing. It requires the database to process a large amount of data, maintain data consistency, and To process these data in real time; therefore, the support of embedded database management system is urgently needed

With the rapid development of digital information technology and network technology, the development of computers has entered the post-PC era. Embedded databases and embedded operating systems are the most important two parts of embedded systems; Hierarchical design, there is bound to be some functional redundancy, and the two may duplicate each other's functions, which undoubtedly causes a waste of resources for embedded systems that are short of resources
