Description

太阳能双供电路 技术领域
本发明涉及供电电路，尤其是涉及太阳能双供电路。
背景技术
太阳能，一般是指太阳光的辐射能量，是一种可再生的新能源。太阳能供电是主要是通过太阳能电池板把太阳能转化为电能，送往可充电电池储存起来，到需要供电的时候再释放出来。但是，太阳能供电受昼夜、晴雨等外在因素的影响，夜晚或者阴天时，就无法充电。
目前现有的太阳能供电系统主要是采用太阳能电池板白天对可充电电池充电，然后再去给负载（装饰或照明灯）供电的方式。但是，如果天气不好或连续几天阴天，太阳能较弱，太阳能电池板没有获得足够的能量对可充电电池充电，造成可充电电池储存的能量不足，导致使用时电压不够，不能给负载供电。
当前的主要理念是通过足够太阳能对可充电电池充电提供给负载使用，在一定程度上利用了绿色太阳能，达到环保节能的目的，但是存在另外一个缺点--供电系统较为单一，无法为负载提供足够电量，导致负载无法运作可能存在。
虽然有些设计方案上增大了可充电电池容量和太阳能电池板功率，在一定程度上可以满足要求。但是，增大可充电电池容量和太阳能电池板功率，成本大大增加，成本大大增加以外并不能解决多日阴天，太阳能电池板不能对可充电电池足够充电，最终还是有时会因可充电电池电压过低，导致负载停止工作的缺点。
发明内容
本发明要解决的技术问题在于，针对现有技术的上述供电系统单一而无法为负载提供足够电量的缺陷，提供一种太阳能双供电路，由可充电电池或不可充电电池对负载供电，解决因供电系统单一而无法为负载提供足够电量的缺陷。
本发明解决其技术问题所采用的技术方案是：构造一种太阳能双供电路，其包括控制模块、太阳能电池板、可充电电池、负载输出端口，还包括不可充电电池。其中，控制模块包括：
主控电路；
连接于太阳能电池板和可充电电池并受主控电路控制，且用于给可充电电池充电的充电电路；
用于检测可充电电池和不可充电电池电压并将检测结果反馈至主控电路的电池电压检测电路；
受太阳能电池板的输出端控制的光控开关；
用于在主控电路控制下，在电池电压检测电路检测到可充电电池或不可充电电池其中一个有电时将可充电电池的输出或不可充电电池的输出通过光控开关接入负载输出端口、在检测到可充电电池和不可充电电池两者均有电时优先将可充电电池的输出通过光控开关接入负载输出端口的供电切换电路。
在本发明的太阳能双供电路中，还包括：
用于连接外部电源的外部电源输入端口；
控制模块还包括：
连接于外部电源输入端口，且用于检测外部电源是否通电并将检测结果反馈至主控电路的电源检测电路；
连接于外部电源输入端口和太阳能电池板并受主控电路控制，且用于在电源检测电路检测到外部电源通电时将外部电源输入端口与充电电路连通和将外部电源输入端口与负载输出端口连通、在电源检测电路检测到外部电源断电时将太阳能电池板与充电电路连通的充电切换电。
在本发明的太阳能双供电路中的控制模块，还包括连接在光控开关与负载输出端口之间的物理开关。
在本发明的太阳能双供电路中的控制模块，还包括连接在光控开关与负载输出端口之间的时控开关。
在本发明的太阳能双供电路中的控制模块，还包括连接于光控开关与负载输出端口之间，且用于调整电压输出的负载供电调整模块。
实施本发明的太阳能双供电路，既环保节能，又可实现双供电，解决了供电系统单一局限的问题。在光照时，太阳能电池板对可充电电池进行充电。对负载供电时，在主控电路控制下，电池电压检测电路检测到可充电电池或不可充电电池其中一个有电时，由可充电电池或不可充电电池对负载输出；在检测到可充电电池和不可充电电池两者均有电时，优先可充电电池对负载输出。
此外，还可以选择使用外部电源直接为负载供电，并且可对可充电电池进行充电，因此，减小光照不够强时对太阳能双供电路充电供电的局限。
附图说明
下面将结合附图及实施例对本发明作进一步说明，附图中：
图1是本发明的太阳能双供电路实施例一的逻辑结构框图；
图2是本发明的太阳能双供电路实施例二的逻辑结构框图。
具体实施方式
如图１所示，图中示出了本发明的太阳能双供电路实施例一的逻辑结构框图。所示的太阳能双供电路中包括控制模块1、太阳能电池板2、可充电电池3、负载输出端口4和不可充电电池5。其中，控制模块1中包括主控电路6、充电电路7、电池电压检测电路8、光控开关13和供电切换电路9。
光照时，太阳能电池板2将太阳能转换成电能，通过受主控电路6控制的充电电路7对可充电电池3进行充电，同时，太阳能电池板2的输出控制光控开关13断开，停止对负载输出。无光照时，太阳能电池板2没有电流输出，光控开关13自动打开，太阳能双供电路对负载供电，电池电压检测电路8检测到可充电电池3或不可充电电池5其中一个有电时并反馈给主控电路6，主控电路6控制供电切换电路9将可充电电池3或不可充电电池5的输出通过光控开关13接入负载输出端口4；电池电压检测电路8检测到可充电电池3和不可充电电池5两者均有电时并反馈给主控电路6，主控电路6控制供电切换电路9优先将可充电电池3的输出通过光控开关13接入负载输出端口4。另外，不可充电电池5可更换。这样，实现了利用太阳能对可充电电池充电，可充电电池优先主供电，不可充电电池备用供电。
如图2所示，图中示出了本发明的太阳能双供电路实施例二的逻辑结构框图。
本发明的太阳能双供电路还可以选择使用外部电源对负载供电和对可充电电池充电。外部电源输入端口10接入外部电源，电源检测电路11检测到外部电源通电时并反馈给主控电路6，主控电路6控制充电切换电路12将外部电源输入端口10与负载输出端口4连通和将外部电源输入端口10与充电电路6连通，外部电源通过受主控电路6控制的供电切换电路9对负载直接供电和通过充电电路2对可充电电池3进行充电。
此外，本发明的太阳能双供电路还可以按需在控制模块中选择添加物理开关14、时控开关15。上述两种开关连接于光控开关13与负载输出端口4之间。天黑时，太阳能电池板2没有电流输出，光控开关自动打开，太阳能双供电路对负载供电，若这时想停止对负载输出，可由物理开关或时控开关断开电流输出，从而停止对负载输出。
本发明的太阳能双供电路也还可以在控制模块中选择添加连接于光控开关13与负载输出端口4之间，且用于调整电压输出的负载供电调整模块16，如灯饰类的闪烁模块。
本发明的太阳能双供电路，解决了供电系统充电供电方式单一局限的问题，既可以利用绿色太阳能达到环保节能的目的，又能保证长期间都能正常提供足够能源给负载使用。灵活充电，智能控制，外部因素对其局限较小，适用性和实用性更广。
