【摘要】：随着我国经济的快速发展,各行各业用电量需求越来越大,电力能源短缺的现象日益突出,节能降耗已经成为全社会关注的热点,能效管理工作显得异常重要。各运营商为了积极响应节能政策号召,需要对各个站点的能耗进行实时检测,保证节能降耗工作的顺利开展。由于基站能耗管理工作存在节点多,布线繁琐,部分线路老化问题,无法对所有进行破线式电能监测,需要一种安装方便、价格低廉的电能监测装置。为了适应特殊安装环境,电流互感器和电压互感器需异地采集电流电压量,并通过同步、传输与计算达到实时监测电量目的。因此本课题提出了一种无线同步电能监测系统。通过对无线同步系统中的异地时钟同步和短距离无线传输两种关键技术的对比分析,选择采用本地网络式同步方式和Zigbee无线传输技术相结合,设计出了整个无线同步系统。在硬件上对整个无线同步系统进行了方案设计,分析系统需要完成的各项功能以及具体实现,设计了以LPC2214为核心处理器的主站无线模块和终端无线模块。然后分别对模块内各部分电路设计,电路功能以及选用器件进行了详细介绍,并完成了整个无线同步系统的软件设计,实现了其各部分功能并进行了测试。通过测试的结果与数据的对比分析,验证了该系统的可行性。
[Abstract]:With the rapid development of economy in China, the demand for electricity consumption in various industries is increasing, and the phenomenon of energy shortage is becoming increasingly prominent. Energy saving and consumption reduction have become the focus of attention of the whole society, and energy efficiency management is extremely important.In order to respond positively to the call of energy-saving policy, operators need real-time detection of energy consumption at various stations to ensure the smooth development of energy-saving and consumption reduction work.Because the base station energy consumption management work has many nodes, the wiring is tedious, part of the line aging problem, can not carry on the broken line type electric energy monitoring to all, need one kind of power energy monitoring device which is convenient to install, the price is low.In order to adapt to the special installation environment, the current transformer and the voltage transformer need to collect the current and voltage quantity in different places, and through synchronization, transmission and calculation to achieve the purpose of real-time monitoring the electric quantity.Therefore, a wireless synchronous power monitoring system is proposed in this paper.By comparing and analyzing the two key technologies of remote clock synchronization and short distance wireless transmission in wireless synchronization system, the local network synchronization mode and Zigbee wireless transmission technology are adopted to design the whole wireless synchronization system.In hardware, the scheme of the whole wireless synchronization system is designed, and the functions and realization of the system are analyzed. The main station wireless module and the terminal wireless module based on LPC2214 are designed.Then each part of the circuit design, circuit functions and the selection of devices are introduced in detail, and the software design of the whole wireless synchronization system is completed, and the functions of each part are realized and tested.The feasibility of the system is verified by comparing the test results with the data.
