【摘要】：随着工业自动化与经济建设的不断发展,电能质量越来越受到人们的关注,各行各业对电能质量的要求也在逐渐增高。因此,为保证电力系统运行的稳定性与安全性,对电能质量指标进行监测与分析有着重要意义。目前,随着嵌入式技术的不断发展,DSP与ARM的性能变得日渐强大,但传统的以DSP与ARM为硬件核心的监测系统,仍存在功能简单、存储容量有限、不易网络化等不足。近年来,Linux操作系统已经成长为一个成熟的嵌入式操作系统,它是一个开源操作系统,可以实现多任务处理,且具有丰富的资源,可以满足各种嵌入式系统的需求；另一方面,虚拟仪器技术是近年来兴起的一项新技术,它具有高度模块化,智能化的特点,被广泛应用于测控系统的开发。为了弥补传统监测系统的不足,本设计在监测设备的ARM模块上移植了μcLinux操作系统,利用其丰富的接口,使用SEGGER公司开发的GUI图形库emWin,以及嵌入式数据库sqlite3,在监测设备上完成了μccLinux用户程序的开发,实现了ARM与PC间的TCP通迅,用户界面设计与数据存储。此外,为了提高对电能质量数据的存储与管理能力,以LabVIEW为软件平台结合Oracle数据库,开发了一套功能全面的电能质量后台监测软件,该软件在PC端为用户提供了接近Windows标准的图形界面,现实了PC与监测设备的网络通信功能,完成了大量电能质量数据的存储与查询。经测试,系统运行稳定,较好地扩展了电能质量监测系统的功能,具有较大的实用意义与较高的市场价值。
[Abstract]:With the continuous development of industrial automation and economic construction, people pay more and more attention to power quality, and the requirements of power quality in various industries are also gradually increasing. Therefore, in order to ensure the stability and safety of power system operation, It is of great significance to monitor and analyze the power quality index. At present, with the development of embedded technology, the performance of DSP and ARM becomes more and more powerful, but the traditional monitoring system based on DSP and ARM still has simple function and limited storage capacity. In recent years, Linux operating system has grown into a mature embedded operating system, it is an open source operating system, can achieve multi-task processing, and has rich resources, On the other hand, virtual instrument technology is a new technology which has been developed in recent years. It has the characteristics of highly modularization and intelligence, and is widely used in the development of measurement and control system. In order to make up for the deficiency of the traditional monitoring system, the 渭 cLinux operating system is transplanted into the ARM module of the monitoring equipment, and its rich interface is used. Using GUI graphics library emWinand embedded database sqlite3 developed by SEGGER Company, the 渭 ccLinux user program is developed on the monitoring equipment, and the TCP communication, user interface design and data storage between ARM and PC are realized. In order to improve the ability of storing and managing power quality data, a comprehensive power quality background monitoring software is developed based on LabVIEW software platform and Oracle database. The software provides users with a graphical interface close to the Windows standard at the PC end, realizes the network communication function between PC and the monitoring equipment, and completes the storage and query of a large number of power quality data. The test results show that the system runs stably and extends the function of the power quality monitoring system, which is of great practical significance and high market value.
