摘要
现有的太阳能照明系统中普遍存在不能准确、有效地检测蓄电池的充电状态和控制器大面积使用时的启停时差问题,为此提出了一种新型控制器。基于单片机89C2051和无线收发模块PTR2000的智能控制器,实现了系统工作状态控制和蓄电池的能量管理,能满足太阳能照明系统稳定运行和准确切换的要求,并实现多个控制器之间的启停一致。实验表明,该控制器效率高,运行稳定,基本解决之前提出的问题,达到了太阳能照明系统对控制器的要求。
Inefficiently and inaccurately detecting the charging state of the storage battery and being unable to simultaneously turn on/off are key problems for existing photovoltaic lighting system which contains a number of separate lighting controllers. A new-style intelligent controller based on MCU 89C2051 and wireless transceiver PTR2000 was proposed to solve these problems. It performs operation status control and energy management of the system and then the lighting system can run steadily and turn on/off simultaneously. Test results showed that the proposed controller is of high operation efficiency and steadiness.
