[0017]电源控制器的核心芯片可以是单片机或DSP,在此使用的是由ATMEL公司研发推出的AVR系列单片机,该款型号是ATmegal28它是采用精简指令集的高速8位单片机,有两路8位PWM,6路分辨率可编程(I到16位)的PWM,8路10位ADC,它是工业级芯片,能够在恶劣的环境条件下可靠的工作;电源控制器由充电电路、放电电路、检测电路组成,它们依次与ATmega 128芯片连接,充电电路连接着太阳能电池板和蓄电池,放电电路分别连接蓄电池组、监控系统和避障系统,检测电路连接蓄电池组和太阳能电池板。太阳能电池板将光能转化为电能,该电能经电源控制器输送给监控系统和避障系统,多余的电能在充电电路的作用下储存在蓄电池组中;当检测电路检测到太阳能电池板转化的电能过低或在夜晚无太阳光时,此时通过放电电路蓄电池组给监控系统和避障系统供电;当该巡逻车停下不工作时,太阳能电池板将转化的电能经充电电路储存在蓄电池组中。
[0018]若遇到连续的阴雨天,蓄电池组中的电能不能及时有效的得到补充,为了不影响巡逻车的日常工作,此时可以通过外接的充电插头,直接利用220V的交流市电,该市电经过整流充电电路的调整,变换为蓄电池组所需的直流充电电压,给蓄电池组进行充电,保障巡逻车的续航里程和日常工作不受影响。
