【摘要】：智能化、分布式太阳能照明系统是当前提倡环保、节能大背景下的一项重要应用技术。基于嵌入式的分布式太阳能照明系统融合了嵌入式技术、传感器技术、网络技术。随着相关领域的技术进步,太阳能照明系统的稳定性与经济性得到大幅度提高,更具有实用价值。本文以NXP公司生产的Contex M0LPC11C14为核心控制器,结合目前应用越来越广泛的LED照明,设计了基于分布式的太阳能照明控制系统。为提高太阳能的转换效率,设计了角度跟踪电路,利用太阳能对蓄电池充电,为LED照明电路提供电源,并利用PID控制提高了系统工作稳定性。加入了市电互补电路,防止长期无光照条件下储能不足时,LED无法正常工作。利用周立功公司生产的CTM1050T设计了CAN总线接口,可以完成CAN总线数据收发,实现了网络化远程控制。在硬件设计中尽量采用近期上市的新型集成IC,电路设计得到简化,性能优良,大大减少了系统电路体积、功耗及成本,且具有较好的扩展性。软件设计采用的算法简单可靠,系统运行稳定。本文设计的太阳能照明系统,理论与实践相结合,硬件与软件相结合,原理与实用技术相结合。制作的测试样机工作稳定可靠,基本达到设计要求。
[Abstract]:Intelligent and distributed solar lighting system is an important application technology under the background of environmental protection and energy saving.The distributed solar lighting system based on embedded system integrates embedded technology, sensor technology and network technology.With the development of technology in related fields, the stability and economy of solar lighting system have been greatly improved, which has more practical value.In this paper, a distributed solar lighting control system is designed with Contex M0LPC11C14 produced by NXP Company as the core controller and LED lighting which is more and more widely used at present.In order to improve the conversion efficiency of solar energy, the angle tracking circuit is designed, the battery is charged by solar energy, the power supply is provided for the LED lighting circuit, and the stability of the system is improved by using the PID control.The complementary circuit is added to prevent the LED from working properly when the energy storage is insufficient under the condition of no light for a long time.The CAN bus interface is designed by using the CTM1050T produced by Zhou Ligong Company. The CAN bus data transceiver can be completed and the network remote control can be realized.As far as possible, the new integrated ICs are adopted in the hardware design, the circuit design is simplified, the performance is excellent, the system circuit volume, power consumption and cost are greatly reduced, and the system has good expansibility.The algorithm used in the software design is simple and reliable, and the system runs stably.The solar lighting system designed in this paper combines theory with practice, hardware with software, principle with practical technology.The test prototype is stable and reliable and meets the design requirements.
