【摘要】：随着我国经济社会高速发展,人民生活水平不断提高,生活用电与企事业单位用电量急剧增长,抄表任务也急剧增加,因此,智能电量采集系统应运而生。而智能电表数据集中器在智能电量采集系统中处于整个系统核心位置,是上下行通信的桥梁。我们研究了市场上主流的数据集中器,并根据数据集中器的基本功能以及应用的技术,选用ARM S5PV210芯片为核心处理器,结合了第三代移动通信3G网络技术,添加了摄像头防盗功能,实现了下行RS-485通信,上行以太网、GPRS/3G通信的数据集中器。本文主要进行了智能电量采集系统中智能电表数据集中器的软硬件应用设计与实现的工作。首先,我们对智能电量采集系统进行了系统的了解,对上位机、集中器、智能电表有了清晰的认识;然后,我们对市场上的设备进行分析对比,并对其所采用的技术进行深入的学习;最后,我们提出了数据集中器的设计方案,并根据方案对软硬件进行细化与实现。数据集中器采用SAMSUNG S5PV210处理器,具有性能高、接口丰富的优点;采用可裁剪的嵌入式Linux操作系统,提供3G通信接口和驱动;结合目前智能电表的通信接口,采用RS-485总线作为下行通信方式;采用以太网、GPRS/3G作为下行通信方式,具有应用广泛、稳定、传输速度快的特点;采用接近开关来触发摄像头拍照,以达到预防盗窃的作用。最后,对本文设计开发过程进行了总结,并对系统下一步需要扩展和改进的工作进行了设计和展望。
[Abstract]:With the rapid development of China's economy and society, constantly improve people's living standards, living power and enterprises with the rapid growth of electricity, meter reading task has increased dramatically, therefore, came into being. The intelligent data acquisition system of intelligent electric meter data collector is at the core position in the whole system of intelligent data acquisition system, is a bridge between uplink and downlink communication. We studied the market mainstream data concentrator, and according to the basic function of data concentrator and the application of the ARM technology, using S5PV210 chip as the core processor, combined with the third generation mobile communication technology of the 3G network, add a camera anti-theft function, achieve RS-485 downlink communication, Ethernet, data concentrator communication. This paper mainly GPRS/3G the application of hardware and software design of intelligent electric meter data collector in intelligent power acquisition system and implementation of the work. First, we The data acquisition system of intelligent understanding of the system, the concentrator of PC, and have a clear understanding of the smart meter; then, we analyzed and compared the devices on the market, and in-depth study of the technology; finally, we put forward the design scheme of data concentrator, and according to the plan the refinement and implementation of software and hardware. The data concentrator using SAMSUNG S5PV210 processor, has advantages of high performance, rich interface; embedded Linux operating system can be cut out, providing the 3G communication interface and drive; combined with the current smart meter communication interface, using RS-485 bus as the downlink communication mode; using Ethernet, GPRS/3G as the downlink communication mode that has wide application, stable characteristics, fast transmission speed; the proximity switch is adopted to trigger the camera, in order to prevent theft. Finally, in this paper. The development process is summarized, and the work that needs to be extended and improved in the next step of the system is designed and prospected.
