Description

能在异常断电后保护车载电子设备的装置
技术领域
本实用新型涉及车载电子设备，尤其涉及一种能在异常断电后保护车载电子设备的装置。
背景技术
目前的车载供电***，会因为某些原因，异常停止电力供应，从而使车载电子设备非正常关机，导致车载电子设备无法保存数据，或者保存的数据文件格式遭到损坏而无法读取等。这些异常最终导致车载电子设备无法完整保存数据，有时甚至会损坏电子设备的软件和硬件，从而给用户带来损失。
实用新型内容
本实用新型是要解决现有技术的上述问题，提出一种能在异常断电后保护车载电子设备的装置。
为解决上述技术问题，本实用新型提出的技术方案是：一种能在异常断电后保护车载电子设备的装置，包括供电电源；对电源进行变换的电源变换模块；接受变换后电能的核心用电***；监测供电电源，把供电电源电压信号发送给核心用电***的电压监测模块；设在电源变换模块与核心用电***之间储备电能，在供电电源供电异常时向核心用电***继续供电的电能存储模块，以便于核心用电***执行存储数据和关机程序。
上述电能存储模块可以为法拉电容。
上述电能存储模块还可以为充电电池。
与现有技术相比，本实用新型可以在供电***异常断电后维持一段时间的电力供应，以便于电子设备保存数据和正常关机。从而保护电子设备，避免损失。
附图说明
下面结合附图和实施例对本实用新型作出详细的说明，其中：
图1为本实用新型较佳实施例的原理框图。
具体实施方式
参看图1，本实用新型包括供电电源，电源变换模块，核心用电***，电压监测模块，电能存储模块。
当汽车电源将电能输入到车载电子设备后，经电源变换模块变换为合适的电压后，给车载电子设备的核心用电***供电，并同时给电能存储模块充电；另外，电压监测模块将供电电源的状态发送给核心用电***。一旦供电电源出现异常或者断电，电源变换模块无电能输出，电能存储模块释放电能给核心用电***。核心用电***立即执行备份操作，写入需要存储的数据，然后关闭***。这样需要保存的数据完整的保存下来，***正常关闭，文件***不会遭到破坏。
在一个实施例中，所述电能存储模块为法拉电容。
在另一个实施例中，所述电能存储模块为充电电池。
以上实施例仅为举例说明，非起限制作用。任何未脱离本发明精神与范畴，而对其进行的等效修改或变更，均应包含于随附申请的权利要求范围之中。
