【摘要】：随着经济的发展和社会的进步，，能源的需求量越来越大，而能源的供应量相对匮乏，加之浪费现象相当突出，使得我国能源供应形势相当严峻。其中与人民生产生活密切相关的电力能源也日益短缺，所以如何提高电力资源的利用率成为当前需要迫切解决的问题。由于公共楼宇照明系统所用的电力资源占据了电力资源的一部分，而传统的楼宇照明方式管理落后，容易造成浪费，所以设计一套易于安装、低功耗的智能照明监控系统显得尤为重要。本文设计的楼宇智能照明监控系统分为智能照明终端部分和主控制端。主控制端发送一帧数据，照明终端通过无线模块接收到数据以后，对数据进行分析判断处理，随后根据命令对灯具进行开关控制，把出现问题的照明灯具的信息反馈给主控制端并对这些灯具进行更换或维修。另外也可以设置时间，实现照明灯具的定时亮灭。本系统智能照明终端采用TI公司生产的MSP430G2553作为主控制器，选用内部带有完整协议栈和外围电路的F8913D ZigBee模块进行数据的收发，外围接有照明终端控制单元、电路信息检测单元、工作状态指示单元、电源模块。主控制端采用MSP430F247作为主控制器，外接有12864液晶显示、DS1302时钟芯片、按键检测单元。在当前照明电路的基础上，ZigBee无线模块设置成ZigBee终端节点安装在照明线路附近。同时在各楼层设置一到两个ZigBee路由器，对照明信息进行中继。除此之外，将主控制端设为ZigBee协调器。协调器启动网络以后，向周围路由器或节点发送信标帧，接收设备收到信标帧以后，发送申请加入网络，加入网络以后将得到网络随机分配的16位网络地址，由此完成了系统初始化开始进行数据的收发。通过主控制端发送一帧数据，照明终端接收到数据以后，按照命令字对灯具进行开关控制或工作状态检测，并把电路故障信息等返回到主控制端，在液晶显示器上显示。采用低功耗单片机，由于其具有休眠模式，能满足系统设计的要求。利用ZigBee的模块化设计，系统可扩展性强，可以直接应用到红外报警和烟雾报警等设计之中。除此之外，ZigBee能实现自组织网络功能，从而使系统设计难度大大降低。该系统在一定程度上能够减少楼宇照明系统中的电力资源浪费，提高能源的利用率，因此具有很大的市场需求和发展潜力。
[Abstract]:With the development of economy and the progress of society, the demand for energy is increasing, and the energy supply is relatively scarce, and the phenomenon of waste is quite prominent, which makes the situation of energy supply in our country very severe. Among them, the power energy which is closely related to people's production and life is also increasingly short, so how to improve the utilization rate of power resources has become an urgent problem to be solved. Because the power resources used in the lighting system of public buildings occupy a part of the power resources, and the traditional lighting mode of buildings is backward in management and easy to waste, so the design is easy to install. Low-power intelligent lighting monitoring system is particularly important. The intelligent lighting monitoring system is divided into intelligent lighting terminal and main control terminal. The main control terminal sends a frame of data. After receiving the data through the wireless module, the lighting terminal analyzes and processes the data, and then controls the lamps and lanterns according to the command. Feedback information about defective lighting to the main control end and replace or maintain these lamps. In addition, you can also set the time to achieve the timing of lighting lights out. The intelligent lighting terminal of this system adopts MSP430G2553 produced by TI company as the main controller, uses F8913D ZigBee module with complete protocol stack and peripheral circuit to send and receive the data, and the peripheral is connected with lighting terminal control unit and circuit information detection unit. Working status indicating unit, power module. The main control terminal uses MSP430F247 as the main controller, with 12864 LCD display DS1302 clock chip and key detection unit. On the basis of the current lighting circuit, the ZigBee wireless module is set up to install the ZigBee terminal node near the lighting line. At the same time, one or two ZigBee routers are set on each floor to relay lighting information. In addition, the main control end is set as ZigBee coordinator. After starting the network, the coordinator sends a beacon frame to the surrounding router or node, and after the receiving device receives the beacon frame, it sends an application to join the network, and after joining the network, it will get a random 16-bit network address assigned by the network. Thus the system initialization is completed and the data is sent and received. A frame of data is transmitted through the main control terminal. After receiving the data, the lighting terminal controls the lamps or detects the working state of the lamps according to the command word, and returns the circuit fault information to the main control terminal and displays it on the LCD. Because of its dormancy mode, the low-power single-chip computer can meet the requirements of system design. With the modularization design of ZigBee, the system is extensible and can be directly applied to infrared alarm and smoke alarm design. In addition, ZigBee can realize the function of self-organizing network, which greatly reduces the difficulty of system design. To a certain extent, the system can reduce the waste of power resources in the building lighting system and improve the utilization of energy, so it has great market demand and development potential.
