现有技术中，Beacon基站的供电方式一般为电池供电。在16个不同的iBeacon厂商的一项研究报告称，电池的寿命一般在1到24个月的范围之内。苹果公司公布的数据显示，在100ms的广告频率下，一颗纽扣电池可以为Beacon基站持续供电1到3个月。因此，如果采用电池供电的方式对Beacon基站进行供电，那么平均每几个月就需要更换电池。如此，在Beacon基站的日常维护中将不可避免的产生如下问题：
(1)、在Beacon基站的日常维护过程中需要投入很高的人力成本，在更换电池的过程中也会造成设备的损耗，且会产生相当数量的废旧电池，对环境造成危害；
(2)在商场等公共场所的非营业时间，Beacon基站也在传输蓝牙信号，这样会造成基站不必要的损耗。
因此，如何研究和开发出一种新的为Beacon基站供电的方式，其能够降低人力成本、减少不必要的损耗是本领域亟待解决的技术难题。

的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
本实用新型针对现有技术中由电池向Beacon基站供电存在的需要投入高的人力成本、造成设备的损耗、对环境造成危害且易造成不必要的损耗的技术问题，提出了一种为Beacon基站供电的光伏发电系统，通过光电转换装置使用光能为Beacon基站供电的方案。商店的光照强度基本都会比自然光强度高，所以可以为基站提供稳定的电能来源。
下面首先介绍光电转换过程的工作原理。光电转换过程是光子将能量传递给电子使其运动从而形成电流。这一过程有两种解决途径，最常见的一种是使用以半导体材料为主要材料的固体装置，另一种则是使用光敏染料分子来捕获光子的能量。
图1为本实用新型提供的一种为Beacon基站供电的光伏发电系统的示意图，由图1可知，所述的为Beacon基站供电的光伏发电系统包括光电转换装置100、光伏控制器200电流转换器300以及Beacon基站400。
其中，所述的光电转换装置100，与所述的光伏控制器200电性连接，用于将所述的Beacon基站工作环境中的光能转换为电能。
光电转换装置诸如可为光伏组件，其是通过光生伏特效应将太阳能转换为电能的材料装置，是由不同规格的太阳能电池，密封后得到的。现有的光伏组件类型有单晶硅、多晶硅、非晶硅和多元化光伏组件。在本实用新型的优选实施方式中，光伏组件使用的是非晶硅光伏组件，属于新型薄膜型太阳能电池，硅材料消耗少，成本较低。本实用新型中采用非晶硅光伏组件主要是考虑到其能够在各种光照强度环境下发电，可以适应Beacon基站所处的公共场所(如商场)内的可见光源的不同强度。
此外，在本实用新型的优选实施方式中，光伏组件由多个太阳能电池串联组成或由多个太阳能电池并联组成或由多个太阳能电池串并联组成。
所述的电流转换器300的输入端与所述的光伏控制器200电性连接；
所述的电流转换器300的输出端与所述的Beacon基站400的通讯组件相连接，用于将转换后的电能传输至所述的Beacon基站，以向所述的Beacon基站供电。
在本实用新型的优选实施方式中，光伏组件、光伏控制器以及电流转换器之间，可采用模拟/数字电路连接，确保能量传输稳定。
如上所述，即为本实用新型提供的一种为Beacon基站供电的光伏发电系统，由光伏组件将Beacon基站工作环境中的光能转换为电能，经过光伏控制器以及电流转换器的
转换后向Beacon基站持续供电，不仅可以避免人工拆卸更换电池给Beacon基站带来的损耗，而且延长Beacon基站的使用寿命。
下面结合具体的实施例，详细介绍本实用新型的技术方案。在该实施例中，Beacon基站位于某大型商场内，为Beacon基站供电的光伏发电系统中，光电转换装置为非晶硅光伏组件。
具体的，非晶硅光伏组件将Beacon基站工作环境中的光能转换为电能并输出给光伏控制器。在商场的营业时间，Beacon基站工作环境中的光能比较充足，Beacon基站处于工作状态，非晶硅光伏组件源源不断的将Beacon基站工作环境中的光能转换为电能。在商场的非营业的时间，Beacon基站工作环境中的光能不足，非晶硅光伏组件无法将Beacon基站工作环境中的光能转换为电能，因此此时Beacon基站处于非工作状态。也即与现有技术中通过电池为Beacon基站供电的方式相比，本实用新型中通过光能供电可以在非营业时间切断电源，延长Beacon基站的工作寿命。
光伏控制器将非晶硅光伏组件输出的电能进行处理。光伏控制器是控制太阳能电池方阵对蓄电池充电以及蓄电池给太阳能逆变器负载供电的自动控制设备。光伏控制器通常有6个标称电压等级：12V、24V、48V、110V、220V、500V，通过使用创新性的最大功率追踪技术，光伏控制器能保证光能电池阵列全天时、全天候的最大效率的工作。可以将光伏组件工作效率提高30％(平均可提高效率为10％-25％)。在本实施例中，光伏控制器的标称电压等级为12V。
DC/DC电流转换器是为转变输入电压后有效输出固定电压的电压转换器，转换电源装置是通过电感不断的储能/放电，最后达到稳定电压/电流输出的转换器。因为目前光伏控制器的标准输出电压最小是为12V，超出Beacon工作时的额定电压。在本实施例中，光伏控制器的标准输出电压为12V，Beacon基站工作时的额定电压为3V，因此，电流转换器在本实施例中为降压型DC/DC电流转换器，其将光伏控制器输出的电能进行电压转换，由降压性电流转换器转换为Beacon基站工作时的额定电压3V，进而为Beacon提供稳定的直流电源。
Beacon基站的通讯组件是Beacon基站的对外通讯模块，也是主要的消耗模块，发送蓝牙信号的组件模块。目前的主流产品中，Beacon在发射功率+4dBm、广播间隔100ms时效果最好，此时一块500mAh的电池可以为基站供电3到6个月。通过该实施例中光伏控制器和电流转换器可以为通讯组件持续稳定提供额定3V电压和5～30uA的额定电流。
如上所述，即为本实用新型提供的一种为Beacon基站供电的光伏发电系统，由光伏组件将Beacon基站工作环境中的光能转换为电能，经过光伏控制器以及电流转换器的转换后向Beacon基站持续供电。通过使用Beacon基站工作环境中的光能为基站持续供电，不仅可以避免人工拆卸更换电池会给基站带来的损耗，而且可以做到与商店营业时间同步，延长基站的使用寿命。
本实用新型的光能供电方式与传统的人工更换电池的方式相比，具有下列优势：
1、减少更换电池的人工成本与意外损耗：
光能供电可以有效延长维护周期，减少更换电池的人工成本，同时由于Beacon基站是一种精密的设备，更换电池过程中可能会带来意外的损耗，而光能供电可以有效减少这样的损耗。
2、做到与商户营业时间同步，延长基站使用寿命：
在商场非营业的时间，如果Beacon基站还在工作，不仅浪费了Beacon的工作效率，而且会减少Beacon基站的使用寿命。而通过光能供电可以在非营业时间切断电源，延长Beacon基站的工作寿命。
3、减少废旧电池产生与环境污染：
使用光能供电的另一个优点就是环保，使用光能供电可以有效减少废旧电池的产生，是一种环保清洁的新能源。
本实用新型中应用了具体实施例对本实用新型的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本实用新型的系统及其核心思想；同时，对于本领域的一般技术人员，依据本实用新型的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本实用新型的限制。
