具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
下面结合附图，具体说明充电系统的电路结构与工作原理。
如图1所示，充电系统10包括相互电性连接的适配器11、充电线缆13以及待充电电子设备15。其中，适配器11用于提供电源信号，充电线缆13将所述电源信号传输至待充电电子设备15，为待充电电子设备15中用于存储电能的储能单元(图未示)提供电能供给。
其中，电源信号包括充电电压与充电电流。其中，电子设备15可通过判断适配器11与充电线缆13是否为原装来确定适配器11与充电线缆13是否适于快速充电。也即是，当电子设备15判定适配器11与充电线缆13为原装，那么即可通过适配器11与充电线缆13执行快速充电；当电子设备15判定适配器11与充电线缆13并非原装，也即是为非原装，那么适配器11与充电线缆13并不适于执行快速充电，而仅能执行常规充电。可以理解，所述快充充电的充电电流大于常规充电电流，当然，快速充电时能够缩短电子设备15的充电时间并提高充电效率。
适配器11可以为直接将交流电源转换为直流电源信号并且直接输出的电压转换接头，也可以为将交流电源转换为直流电源信号并进行存储的储能电源，如充电宝一类的可移动储能电源。
具体地，适配器11包括第一接口H1、第一处理控制单元111以及供电单元113。第一接口H1包括第一电源引脚Vbus1、第一数据传输引脚D1、第二数据传输引脚D2以及第一接地引脚G1。
其中，供电单元113电性连接第一电源引脚Vbus1与第一接地引脚G1，供电单元113用于通过第一电源引脚Vbus1与第一接地引脚G1输出并提供电源信号中的充电电压与充电电流。本实施例中，第一电源引脚Vbus1与第一接地引脚G1配合可以提供第一充电电压与第一充电电流或者第一充电电压与第二充电电流。第二充电电流小于第一充电电流，第一充电电流对应适配器11的快速充电，第二充电电流对应适配器11的常规充电。本实施例中，第一充电电压为5V，第一充电电流为4A-6A，第二充电电流为1A。
第一处理控制单元111电性连接于第一数据传输引脚D1或第二数据传输引脚D2，也即是第一数据传输引脚D1与第二数据传输引脚D2不同时与第一处理控制单元111电性连接。本实施例中，第一处理控制单元111电性连接于第二 数据传输引脚D2，所述第一数据传输引脚D1悬空，也即第一数据传输引脚D1是未连接至第一处理控制单元111及其他电子元件和导电电路。在适配器11上电工作后，第一处理控制单元111首先通过第二数据传输引脚D2输出数据信号至充电线缆13以及待充电的电子设备15。
在一实施方式中，数据信号中包括有如图2所示的第一校验信号。其中，图2为第一校验信号的波形示意图，如图2所示，第一校验信号为包括n个脉冲的脉宽调制信号(Pulse Width Modulation，PWM信号)，每个脉冲包括第一时间宽度T。本实施中，n为8，当然，在本发明其他变更实施例中，n可以依据实际需要进行调整，例如为6、7、9、10等大于1的自然数。
在本发明本另一施例中，第一处理控制单元111电性连接于第一数据传输引脚D1，所述第二数据传输引脚D2悬空，也即第二数据传输引脚D2未连接至其他电子元件或者导电电路。第一处理控制单元111可通过第一数据传输引脚D1传输上述PWM信号。
所述第一校验信号用于校验充电线缆13以及适配器11是否为原装，以及是否适于传输第一充电电流。其中，当待充电的电子设备15接收到包含有第一校验信号的数据信号就能够表明充电线缆13以及适配器11为原装，对应地，当待充电的电子设备15并未接收到数据信号，就能够表明充电线缆13和/或者适配器11并非原装。进一步，由待充电的电子设备15执行针对第一校验信号的校验。当校验通过时，适配器11通过第一电源引脚Vbus1提供第一充电电流，当校验未通过时，适配器11通过第一电源引脚Vbus1提供第二充电电流。
较佳地，当校验通过时，第二数据传输引脚D2还接收自待充电的电子设备15通过充电线缆13提供反馈信息，其中，反馈信息包括有验证完成信号或者说验证完成信号表示反馈信息。第一处理控制单元111在接收到验证完成信号时，则控制第一电源引脚Vbus1提供第一充电电流。当校验未通过时，第一处理控制单元111无法接收到验证完成信号，则相应控制第一电源引脚Vbus1提供第二充电电流。
进一步，第一处理控制单元111在第一预定时间段未接收到验证完成信号时，表明校验未通过，则相应控制第一电源引脚Vbus1提供第二充电电流。第一预设时间段可以依据实际需求进行设定，例如3秒。

对应地，当第一寻址引脚ID1接收到验证完成信号时，验证完成信号通过与第一电阻R1相连的第六数据传输引脚D6与第一寻址引脚ID1传输至第四数据传输引脚D4，然后第二电源引脚Vbus2传输第一充电电流至所述第三电源引脚Vbus3。反之，当第四数据传输引脚D4未接收到验证完成信号时，第二电源引脚Vbus2传输第二充电电流至所述第三电源引脚Vbus3。

第二电阻R2与第一电阻R1通过第一、第二寻址引脚ID1、ID2串联在第二数据传输线L2上，且第一电阻R2与第一电阻R1相互配合以作为第六数据传输引脚D6的下拉电阻，从而使得与第六数据传输引脚D6电性连接的第八数据传输引脚D8与第二寻址引脚ID2相互配合以便进行数据传输。本实施例中，第一电阻R1的电阻值为5KΩ，第二电阻R2的电阻值为10KΩ。
第二处理控制单元151电性连接于第二寻址引脚ID2与第八数据传输引脚D8以接收包含有第一校验信号的数据信号，以判断所述数据信号是否为预设的数据信号。具体地，当所接收到的数据信号为所预设的数据信号时，所述第二处理处理控制单元151判定所述充电线缆13为原装的充电线缆。当然，所述第二处理处理控制单元151在判定所述充电线缆13为原装的充电线缆的同时，也可以一并判定所述适配器11亦未原装的适配器。本实施例中，预设的数据信号即为时间跨度为第一预设T1时间值的PWM信号。
较佳地，第二处理控制单元151进一步针对第一校验信号进行校验，以及当所述第一校验信号校验完成后依据校验结果确定是否输出验证完成信号。也即是当所述第一校验信号校验通过后，表征适配器11与充电线缆是适于快速充电的，第二处理控制单元151控制电源单元153进入快充充电模式，也即是控制所述电源单元153能够通过所述第四电源引脚Vbus4与所述第四接地引脚G4接收第一充电电流，同时，第二处理控制单元151通过第二寻址引脚ID2与第八数据传输引脚D8或仅通过第八数据传输引脚D8输出验证完成信号并通过充电线缆13传输至适配器11；反之，当所述第一校验信号未通过校验时，则表征适配器11与充电线缆不适于快速充电的，第二处理控制单元151控制电源单元153 不进入快充充电模式，也即是控制所述电源单元153能够通过所述第四电源引脚Vbus4与所述第四接地引脚G4接收第二充电电流，同时，第二处理控制单元151并不输出验证完成信号。需要说明的是，第二处理控制单元151预先将第二寻址引脚ID2设置为输入状态。
较佳地，所述验证完成信号中包括有电源单元153的电量及所述电源单元153允许输入的最大电流流量信息，以便于适配器11确定提供第一充电电流的大小或者时间长短。
此外，验证完成信号具体是通过第二寻址引脚ID2与第八数据传输引脚D8或仅通过第八数据传输引脚D8进行传输取决于该验证完成信号的类型。具体地，当所述验证完成信号为差分信号时，则通过第二寻址引脚ID2与第八数据传输引脚D8进行传输；当所述验证完成信号为单端信号时，则仅通过第八数据传输引脚D8进行传输。
对应地，当校验通过并且向适配器11提供验证完成信号后，即可自第四电压引脚Vbus4接收第一充电电流为电源单元153进行充电；当校验未通过，通过所述第四电压引脚Vbus4接收第二充电电流为电源单元153充电。
较佳地，第二处理控制单元151自接收到所述第一校验信号并且进行校验后，若校验通过，则在第一预定时间输出验证完成信号，并且通过所述第二寻址引脚ID2与第八数据传输引脚D8传送至适配器11，也即是当所述第一校验信号通过校验后，第二处理控制单元151自接收到所述第一校验信号的第一预设时间输出验证完成信号至所述适配器11；若校验未通过，则无法在第一预定时间输出验证完成信号。其中，所述验证完成信号表示所述反馈信息。
第四接口H4为USB2.0规范的Micro B型接口，其中，第四电源引脚Vbus4为电源引脚Vbus，第七数据传输引脚D7则对应为数据传输引脚D+，第八数据传输引脚D8则对应为数据传输引脚D-，第四接地引脚G4为接地引脚GND。
需要说明的是，前述的待充电的电子设备15处于充电状态，也即是第四电源引脚Vbus4配合第四接地引脚G4为电子设备15提供第一充电电流或者第二充电电流至电源单元153。电子设备15也可以处于数据信号传输状态，此时第二寻址引脚ID2与第七数据传输引脚D7或第八数据传输线D8相互配合执行数据信号的传输；或者所述第七数据传输引脚D7与第八数据传输线D8相互配 合执行数据信号的传输。
请参阅图3，其为本发明另一实施例中充电系统的整体连接结构示意图。如图3所示，充电系统20与充电系统10结构与连接关系基本相同，区别在于：
对应适配器21，第一处理单元211与第一数据传输引脚D1电性连接，所述第二数据传输引脚D2悬空，也即第二数据传输引脚D2未连接至其他电子元件或者导电电路。
对应充电线缆，第一数据传输线L1与所述第一寻址引脚ID1之间电连接第一电阻R1，也即是将第一电阻R1电性连接于第一数据传输线D1与第一寻址引脚ID1之间。由此可见，所述适配器21上与所述第一寻址引脚ID1相连的第一数据传输线L1相连的第一数据传输引脚D1与所述第一处理控制单元211电连接。即，当第一数据传输线L1与第一寻址引脚ID1相连时，则第一数据传输引脚D1与第一处理控制单元211电连接。
第二电阻R2与第一电阻R1通过第一、第二寻址引脚ID1、ID2串联在第一数据传输线L1上，以作为第五数据传输引脚D5的下拉电阻，从而使得第七数据传输引脚D7与第二寻址引脚ID2相互配合以便进行数据传输。本实施例中，第一电阻R1的电阻值为5KΩ，第二电阻R2的电阻值为10KΩ。
对应待充电的电子设备25，第二处理控制单元251电性连接于第二寻址引脚ID2与第七数据传输引脚D7以接收第一校验信号，并且针对第一校验信号进行校验，以及有校验完成后依据校验结果确定是否输出验证完成信号。第二处理控制单元151自接收到所述第一校验信号并且进行校验后，若校验通过，则在第一预定时间输出验证完成信号至所述第二寻址引脚与第七数据传输引脚D7，若校验未通过，则无法在第一预定时间输出验证完成信号。当充电系统20上电工作时，第五数据引脚D5与第一寻址引脚ID1相互配合可用于让线缆13在适配器11与待充电的电子装置15之间进行数据信号的传输。具体的，当第三数据传输引脚D3自所述第一数据传输引脚D1接收所述第一校验信号时，该第一校验信号通过第五数据引脚D5、第一电阻R1传输至第七数据引脚D7、第一寻址引脚ID1及第二寻址引脚ID2。第二处理单元251则自第七数据引脚D7与第二寻址引脚ID2接收所述第一校验信号并且执行校验。
对应地，当第一寻址引脚ID1接收到验证完成信号时，验证完成信号通过 与第一电阻R1相连的第五数据传输引脚D5与第一寻址引脚ID1传输至第三数据传输引脚D3，然后第二电源引脚Vbus2传输第一充电电流至所述第三电源引脚Vbus3。反之，当第三数据传输引脚D3未接收到验证完成信号时，第二电源引脚Vbus2传输第二充电电流至所述第三电源引脚Vbus3。
请参阅图4，其为图1-3所示的待充电的电子设备15针对第一校验信号执行校验的流程图。
其中，第二处理单元151执行校验时具体包括步骤：
步骤401，接收所述适配器发送的第一校验信号。
在本实施方式中，所述第二处理控制单元151自所述第二寻址引脚ID2与第八数据传输引脚D8接收第一校验信号。其中，第一校验信号为脉宽调制信号(Pulse Width Modulation，PWM信号)。
在另一实施方式中，所述第二处理控制单元151自所述第二寻址引脚ID2与第七数据传输引脚D7接收第一校验信号。
步骤402，分析所述第一校验信号，并从所述第一校验信号中获取时间宽度等于第一时间的脉冲信号的数量。
较佳地，在步骤402分析所述第一校验信号时，当脉冲的时间宽度等于第一时长时表示成功获取一个脉冲，脉冲数量增加1。
步骤403，比较所述数量与预设阈值是否相等；若是，则执行步骤404；若否，则流程结束。
当该获取到的时间宽度为第一时间的脉冲信号的数量等于预设值时，表明所述第一校验信号校验通过；否则，即该获取到的时间宽度为第一时间的脉冲信号的数量与预设值不相等时，表明所述第一校验信号校验未通过。当第一校验信息未通过校验时，所述适配器11输出第二充电电流给电子设备15供电。
较佳地，当脉冲的时间宽度不等于第一时长时表示获取脉冲失败，则记录脉冲捕捉失败的次数，当捕捉失败的次数大于第二阈值时，则表示校验未通过。
可变更地，在本发明其他实施例中，当一脉冲信号的时间宽度大于第一时间时，也表示该脉冲信号未通过校验。第二阈值可以依据实际需求进行设定，例如10。
较佳地，第一预设时间可以与需要分析的n个脉冲信号的时间长度总和相同。
步骤404，生成快充验证完成的信号，并将所生成的验证完成信号通过第二寻址引脚第二寻址引脚发送给适配器，以及控制所述适配器响应所述验证完成信号将第二充电电流提高至第一充电电流。
具体的，在一实施方式中，该验证完成信号可通过第二寻址引脚ID2与第八数据传引脚D8或只第八数据传输引脚D8传输至适配器。当该验证完成信号为差分信号时，则该验证完成信号通过第二寻址引脚ID2与第八数据传输引脚D8传输至适配器。当该验证完成信号为单端信号时，在该该验证完成信号仅通过第八数据传输引脚D8传输至适配器。
在另一实施方式中，该验证完成信号可通过第二寻址引脚ID2与第七数据传引脚D7或只第七数据传输引脚D7传输至适配器。当该验证完成信号为差分信号时，则该验证完成信号通过第二寻址引脚ID2与第七数据传输引脚D7传输至适配器。当该验证完成信号为单端信号时，在该该验证完成信号仅通过第七数据传输引脚D7传输至适配器。
请一并参阅图5，所示为本发明一实施例所提供的验证所述适配器与所述线缆是否为原装的方法步骤流程图。如图5所示，该方法包括步骤：
步骤501，当所述第四接口H4通过充电线缆13、23连接至适配器11、21时，判断第二处理控制单元151是否自所述第二寻址引脚ID2与所述第七数据传输引脚D7或自所述第二寻址引脚ID2与第八数据传输引脚D8接收到数据信号。若是，则执行步骤502；若否，则执行步骤503。
可以理解，在此之前，适配器11的第一接口H1与充电线缆13的第二接口H2插接并且电性连接，充电线缆13的第三接口H3与待充电的电子设备15的第四接口H4插接并且电性连接，且适配器11上电工作。
步骤502，判定所述充电线缆13、23为原装。
在本实施方式中，当第二处理控制单元151自所述第二寻址引脚ID2与所述第七数据传输引脚D7或自所述第二寻址引脚ID2与第八数据传输引脚D8接收到数据信号时，第二处理控制单元151判定充电线缆13为原装，也即是判定其为原装的充电线缆13。较佳地，第二处理控制单元151还进一步判定适配器 11也为原装，也即是判定其为原装的适配器11。
其中，原装的充电线缆11与所述电子设备15相连的第三接口H3包括第一寻址引脚ID1，且第一数据传输线L1或者第二数据传输线L2与第一寻址引脚ID1之间电性连接第一电阻R1。第一电阻R1与第二电阻R2配合以使得第一数据传输线L1或者第二数据传输线L2能够正常传输数据信号。
原装的适配器11包括第一处理控制单元111、211以及用于与充电线缆13、23电性连接的第一数据传输引脚D1与第二数据传输引脚D2，第一数据传输引脚D1与所述第二数据传输引脚D2不同时与第一处理控制单元111、211电性连接，第一数据传输引脚D1或者第二数据传输引脚D2用于传输所述数据信号。
步骤503，判断充电线缆13、23与适配器11、21至少其中之一为非原装。
具体地，对应第二接口H2与第一接口H1，第二电源引脚Vbus2电性连接第一电源引脚Vbus1，第二接地引脚G2对应第一接地引脚G1，第三传输引脚D3对应第一数据传输引脚D1，第四数据传输引脚D4对应第二数据传输引脚D2。对应第四接口H4与第三接口H3，第四电源引脚Vbus4电性连接第三电源引脚Vbus3，第四接地引脚G4电性连接第三接地引脚G3，第七传输引脚D7电性连接第五数据传输引脚，第八数据传输引脚D8电性连接第六数据传输引脚D6，第二寻址引脚ID2电性连接第一寻址引脚ID1。
当适配器11上电以后，第一处理控制单元111自第二数据传输引脚D2输出第一校验信号，所述第一校验信号通过充电线缆13的第二数据传输线L2、第一电阻R1、第一寻址引脚ID1、第二寻址引脚ID2与第七传输引脚D7或第八传输引脚D8传输至第二处理控制单元151。
本实施例中，适配器11中第一处理控制单元112选择性与第一数据传输引脚D1或者第二数据传输引脚D2其中之一电性连接，充电线缆13在第一数据传输线L1与第一寻址引脚ID1设置第一电阻R1或者第二数据传输线L2与第一寻址引脚ID1设置第二电阻R1，从而构成原装的适配器11与原装的充电线缆13。如此一来，当电子设备15通过与第一寻址引脚ID1电性连接的第二寻址引脚ID2接收到数据信号，就能够判定适配器11与充电线缆13均为原装。
反之，现有技术中的适配器的第一数据传输引脚D1与第二数据传输引脚D2是相互短接在一起，故此，现有的适配器无法发送数据信号至待充电的电 子装置，也即电子装置如法接收到适配器发送的数据信号。当所述适配器所原装，但线缆为非原装时，现有的线缆需要通过两条数据线共同协作才能传输数据信号，由于原装的适配器只有一个数据传输引脚与第一处理控制单元112连接，故此，该原装的适配器无法通过现有的充电线缆(非原装的线缆)将该数据信号发送给电子装置。如此，当所述电子装置未接收到数据信号，则可判定适配器11与充电线缆13至少其中之一为非原装，也即是，若接收到所述数据信号并当所述线缆15为原装时，则一并判定所述适配器11也为原装。
较佳地，当所述充电线缆13与所述适配器11为原装时，所述第二控制单元151通过所述第二寻址引脚ID2与所述第七数据传输引脚或第八数据传输引脚发送验证完成信号，其中，该验证完成信号中包括有电源单元153的电量及所允许输入的最大电流流量信息。
需要说明的是，当电子设备15判定所述充电线缆13与所述适配器11为原装时，则可以确认所述充电线缆13与所述适配器11适于提供较大的充电电流执行为电子设备15进行快速充电，而不会对所述充电线缆13与所述适配器11产生损坏。由此，当所述充电线缆13与所述适配器11为原装时，所述第二控制单元151控制电源单元153进入快速充电模式，并将通过所述第四电源引脚Vbus4与所述第四接地引脚G4的电流提高至第一充电电流。
较佳地，第二处理控制单元151接收到所述数据信号并判定所述适配器11与充电线缆13为原装时，第二处理控制单元151还进一步验证所述数据信号是否为预设的数据信号，以进一步更为准确地判定所述适配器11与充电线缆13是否适于快速充电。
具体地，所述数据信号中还包含有第一校验信号，第二处理控制单元151分析所述第一校验信号以获取第一校验信号的中时间宽度等于第一时间宽度的脉冲信号的数量，当所获取数量与预设阈值相同，表示该第一校验信号校验通过，第二处理控制单元151输出验证完成信号，并且通过第二数据传输线L2和第二寻址引脚ID2、第一寻址引脚ID1、第一电阻R1、第四数据传输引脚D4、第二数据传输引脚D2传输至适配器11的第一处理控制单元111，第一处理控制单元111接收到该验证完成信号后相应地自第一电源引脚Vbus1提供第一充电电压和/或第一充电电流至第二电源引脚Vbus2，并相应地通过第三电源引脚 Vbus3、第四电源引脚Vbus4传输至电源单元153，以对电源单元153执行快速充电。所谓的快速充电是指适配器11的充电电流由第二充电电流提高到第一充电电流。
当第二处理控制单元151从第一校验信号中获取到的时间宽度等于第一时间宽度的脉冲信号的数量与预设阈值不相同时，表示校验未通过，第二处理控制单元151便不输出验证完成信号。适配器11的第一处理控制单元111相应地在不能接受到验证完成信号。此时，适配器11自第一电源引脚Vbus1提供第二充电电流至第二电源引脚Vbus2，并相应地通过第三电源引脚Vbus3、第四电源引脚Vbus4传输至电源单元153，以对电源单元153执行常规充电。相较于现有技术，通过适配器11、充电线缆13与电子设备15在指定引脚是否有匹配预定的数据信号的传输来判定配器11、充电线缆13是否为原装，以及在原装时是否适于提供较大的第一充电电流的快速充电。
进一步，待充电的电子设备15针对数据信号中包含的第一校验信号校验判定，从而能够有效识别充电线缆13是否适于传输快速充电的第一充电电流，以防止充电线缆13的设计规格无法承载较高的第一充电电流而被损坏，甚至造成适配器11或者待充电的电子设备15的损坏。
本文中应用了具体个例对本发明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发明的核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，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发明的限制。
