《无线电力抄表系统的研究与设计》-毕业论文.doc

w 摘 要 远程无线自动电抄表系统是提高供电企业用电管理水平的需要，全面实施自动电抄表系统具有极大的经济和社会价值，自动电抄表系统不但可以加强对用户用电情况的监督，还增强了对电网商业化运营的监督，从而为企业的经营分析决策奠定基础。 论文将zigbee无线通信技术应用到无线抄表系统中, 把用户电表用电数据收集到一个数据集中器, 然后通过无线方式把获得的数据信息送到数据管理中心,同时,数据管理中心可访问和控制任何一个在 ZigBee 网络中的设备,来实现远程控制功能。 基于单片机和zigbee无线网络传输技术，完成了包括主控制器STM32F101R6T6模块、电源模块、通信模块、zigbee模块、复位电路、存储器模块的数据采集终端的硬件电路设计。 采用C语言编程，完成了包括系统底层处理模块、运行模块、时钟处理模块、存储器读写模块、通讯模块、清零模块的软件设计。 通过RS485与UART通信测试、zigbee无线通信测试，验证了数据采集终端系统的部分功能。测试结果表明该系统可以应用于简单的点对点无线通信。 关键词：zigbee，RS485，单片机，串口通信，自动电抄表系统 ABSTRACT Wireless remote automatic electric meter reading system to improve the supply of corporate power management level, the full implementation of the automatic electric meter reading system has great economic and social value, automatic electric meter reading system will not only strengthen the supervision of the user of electricity in also enhance the supervision of the commercial operation of the grid, and thus lay the foundation for business analysis and decision. The paper will zigbee wireless communications technology to the wireless meter reading system, the user-meter electricity data collection to a data concentrator, and then through a wireless data obtained to the data management center, at the same time, the data management center can access and control any device in the ZigBee network, the remote control function. Microcontroller and zigbee wireless network transmission technology, to complete the the host controller STM32F101R6T6 module, power modules, communication modules, zigbee module, reset circuit, memory module, data acquisition terminal hardware circuit design. Using the C programming language, complete system underlying processing module, run the module, the clock processing module, memory, reading and writing modules, communication modules, clear module software design. RS485 and UART communications test, zigbee wireless communications test and verify some of the features of the data collection terminal. The test results show that the system can be ap
