【摘要】：电力行业已经成为了国民经济和人民生活的基础能源产业。近年来,我国电力行业也有了突飞猛进的发展。但随着我国经济社会的发展,用电量剧增,传统的人工抄表收费方式已经不能满足现代化电力管理的要求。在电能使用量大幅度增加的情况下,电力公司对电能数据的及时采集与分析工作遇到了日益严重的挑战,已经成为当前电力公司急需解决的关键问题之一。本文针对上述问题,基于嵌入式系统的速度快,芯片体积更小、功能更强,并且具有简单、高效、易于升级的特点,采用现代的嵌入式技术来设计手持式自动抄表系统。系统具备快速读取用户电表内的电能数据,并进行快速数据处理和数据上传的功能,能够方便抄表员采集电能数据,做到数据采集高效、无误、完整的特点。本文完成的主要研究工作内容如下： (1)根据设计手持式自动抄表系统的功能要求,在对国内外嵌入式技术和案例的分析、研究之后,完成了一种以STM32F103ZET6芯片为核心,具有多种外部存储器设备、红外通信设备、USB设备和以太网设备为一体的手持式自动抄表系统。 (2)基于系统要求具有便携、快速、稳定和完整等特点,并根据嵌入式系统硬件设计要求、以及各个功能模块的软件驱动要求,设计完成了具体功能设计的程序流程,并在流程的基础上完成软件控制程序的编写。对于红外通信模块,主要完成了基于红外通信规约规范的数据抄写功能；对数据存储模块,主要完成数据在各个存储器上的数据存储功能；对数据上传模块,分别完成了通过USB和以太网两种方式进行抄表系统与上位机之间的数据通信。 (3)对系统的硬件和软件进行了联合调试,结果表明：系统样机的各项功能基本达到了系统设计方案的要求。
[Abstract]:Electric power industry has become the basic energy industry of national economy and people's life. In recent years, the electric power industry of our country also has the development by leaps and bounds. But with the development of our country's economy and society, the electricity consumption is increasing dramatically, the traditional manual meter reading and charging method can not meet the demand of modern electric power management. With the large increase of electric energy usage, the timely acquisition and analysis of electric energy data by power companies has met with increasingly serious challenges, which has become one of the key problems that power companies urgently need to solve. Aiming at the above problems, based on the high speed of embedded system, smaller chip size, stronger function, simple, efficient and easy to upgrade, this paper uses modern embedded technology to design the hand-held automatic meter reading system. The system has the function of reading the electric energy data of the user meter, processing and uploading the data quickly, which can make it convenient for the meter reader to collect the electric energy data, so that the data collection is efficient, correct and complete. The main contents of this paper are as follows: 1) according to the functional requirements of the design of the hand-held automatic meter reading system, after analyzing the embedded technology and cases at home and abroad, a kind of STM32F103ZET6 chip as the core, with a variety of external memory devices, is completed. Infrared communication equipment USB equipment and Ethernet equipment as one of the hand-held automatic meter reading system. Based on the characteristics of portable, fast, stable and complete system, and according to the hardware design requirements of embedded system and the software driving requirements of each functional module, the program flow of specific function design is designed and completed. And on the basis of the process to complete the preparation of software control programs. For the infrared communication module, the data copying function based on the infrared communication protocol specification is mainly completed; the data storage module mainly completes the data storage function on each memory; the data upload module, The data communication between the meter reading system and the host computer is accomplished by USB and Ethernet respectively. 3) the hardware and software of the system are debugged jointly. The results show that the functions of the system prototype basically meet the requirements of the system design scheme.
