下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的充电器、数据线、充电设备和电子设备进行详细地说明。
请同时参阅图1、图2和图3，其中，图1是本申请实施例提供的充电设备的电路图；图2是本申请实施例提供的充电器的电路图；图3是本申请实施例提供的数据线的电路图。
在应用中，本申请实施例提供的充电设备与本申请实施例提供的电子设备相互匹配(或者还可以称之为标配)。当本申请实施例提供的充电设备与本申请实施例提供的电子设备连接时，能够经数据引脚对该电子设备进行非PD充电或者经CC引脚对该电子设备进行PD充电。另外，当本申请实施例提供的充电设备与非标配的待充电设备连接时，也可以对该非标配的待充电设备进行PD充电或者非PD充电，具体的充电模式可以根据与非标配的待充电设备的充电协议协商确定。
在具体实施中，本申请实施例提供的充电设备能够通过检测数据引脚和CC引脚上的电信号，判断与其连接的待充电设备是否为标配的待充电设备。
其中，上述数据引脚可以是现有Type-C接口中具有的数据引脚，例如：D+引脚和D-引脚，在具体实施中，上述数据引脚还可以是其他引脚，例如：第三代通用串口总线(USB 3.0)中的信号传输引脚(TX引脚和RX引脚)等。为便于说明，如图1至图5所示实施例中仅以上述数据引脚包括D+引脚和D-引脚为例进行说明，在此不作具体限定。
具体的，如图1或图4所示，本申请实施例提供的电子设备3包第二Type-C接口，且该第二Type-C接口内的D+引脚、D-引脚、CC引脚、VBUS引脚以及GND引脚与数据线2的第一Type-C接口22内的D+引脚、D-引 脚、CC引脚、VBUS引脚以及GND引脚一一对应连接，且第二Type-C接口内的D+引脚通过第三电阻31(即上拉电阻)连接至电源单元32，第二Type-C接口内的CC引脚通过第四电阻33(即下拉电阻)连接至GND引脚。
在应用中，充电设备连通电源与电子设备3时，电源单元32能够向D+引脚提供电源，以改变D+引脚上的电信号，且CC引脚一端与充电器1内的目标电源121连接，另一端通过第四电阻33接地，同样能够改变CC引脚上的电信号。
其中，D+引脚通过第三电阻31连接至电源单元32，使得充电设备基于D+引脚上的电信号获知与标配的待充电设备连接。
另外，CC引脚通过第四电阻33接地，使得充电设备基于CC引脚上的电信号获知与支持PD充电的待充电设备连接。
需要说明的是，在具体实施中，本申请实施例提供的充电设备还能够与不支持PD充电的待充电设备标配，即本申请实施例提供的充电设备标配的待充电设备内的CC引脚不经过下拉电阻接地。另外，上述通过第三电阻31连接至电源单元32的数据引脚还可以是D-引脚，在此不作具体限定。
请参阅图1和图2，充电器1，包括：第一Type-A接口11和协议控制模块12；第一Type-A接口11包括CC引脚、数据引脚、VBUS引脚和GND引脚，协议控制模块12包括目标电源121，CC引脚以及目标电源121分别与协议控制模块12的第一端连接，数据引脚与协议控制模块12的第二端连接；
在工作中，在充电器1通过数据线2与待充电设备连接的情况下，若协议控制模块12获取经CC引脚传输的通信信号，则充电器1对所述待充电设备进行PD充电；若协议控制模块12获取经数据引脚传输的通信信号，则充电器1用于对所述待充电设备进行非PD充电。
在具体实施中，上述PD充电可以理解为：基于PD通信协议的快速充电模式，该PD通信协议的通信信号经CC引脚传输。
需要说明的是，如图1所示实施例中将数据引脚标记为：D+引脚或者D-引脚(即D+/D-)，另外，在实际应用中，第一Type-A接口中可以包括D+引脚和D-引脚，且D+引脚和D-引脚中的至少一个与切换模块24连接。
另外，上述非PD充电可以是基于数据引脚传输的通信信号的充电模式， 例如：在数据引脚为D+引脚和D-引脚的情况下，该非PD充电可以是基于D+/D-通信协议(即经D+引脚和D-引脚传输的通信信号的通信协议)的充电信号进行充电的方式。具体的，协议控制模块12中可以预先配置有PD通信协议和预设通信协议，该预设通信协议为经数据引脚传输的通信信号的通信协议，在该充电器1通过标配的数据线与标配的待充电设备连接时，能够基于该预设通信协议对标配的待充电设备进行标配充电，其中，所述标配的待充电设备可以理解为：配置有本申请提供的充电设备的待充电设备，且该待充电设备中配置有上述预设通信协议。另外，上述协议控制模块12中还配置有通用的D+/D-通信协议，本实施方式中，非PD充电处理单元13能够通过D+引脚和D-引脚实现非PD充电协议中的通信过程，例如：数据负信号(DataMinus，DM)和数据正信号(Data Positive，DP)充电通信。
需要说明的是，上述DM和DP充电通信的具体原理与过程与现有技术中的DM和DP充电通信的具体原理与过程相同，在此不再具体阐述。
这样，在该充电器1通过数据线与非标配且不支持PD充电的待充电设备连接时，可以基于该通用的D+/D-通信协议对待充电设备进行普通充电。
在具体实施中，上述目标电源121可以具体为：与电阻串联的电压源，该电压源可以是充电器1内的VBUS走线或者VBUS引脚，以在充电器1连接电源时，该目标电源121向CC引脚输送电流。
本申请实施例提供的充电器，包括第一Type-A接口和协议控制模块，且所述第一Type-A接口包括CC引脚、数据引脚、VBUS引脚和GND引脚，所述CC引脚以及所述VBUS引脚与所述协议控制模块的第一端连接。这样，在与该充电器连接的数据线的Type-A接口也具有匹配的CC引脚时，充电器内的VBUS引脚能够通过CC引脚与支持PD充电的待充电设备的第四电阻接地，从而使得CC引脚上的电信号产生变化，以供数据线或充电器获取该电信号，并据此确定该充电设备对待充电设备进行PD充电。此时，协议控制模块经CC引脚获取到充电信号，并且能够基于该CC引脚上传输的PD充电协议的通信信息，对待充电设备进行PD充电，从而使采用Type-A接口的数据线与本申请提供的充电器连接时，能够支持PD充电协议。
如图1和图3所示，本申请实施例提供的数据线2，包括：第二Type-A 接口21、Type-C接口22以及连接于第二Type-A接口21与Type-C接口22之间的线缆23述线缆23上设置有切换模块24；第二Type-A接口21和Type-C接口22均包括CC引脚、数据引脚、VBUS引脚和GND引脚，且所述第二Type-A接口和Type-C接口22中的数据引脚、VBUS引脚和GND引脚一一对应连接，线缆23包括CC走线，所述CC走线的两端分别连接第二Type-A接口21中的CC引脚和Type-C接口22中的CC引脚。
在工作中，切换模块24基于第二Type-A接口中的CC引脚上传输的电信号和数据引脚上传输的电信号，控制CC走线连通或者断开。
在具体实施中，在CC走线连通时，第二Type-A接口21中的CC引脚和Type-C接口22中的CC引脚连通；在CC走线断开时，第二Type-A接口21中的CC引脚和Type-C接口22中的CC引脚断开。另外，上述第二Type-A接口21可以与第一Type-A接口11匹配，例如：第一Type-A接口11为Type-A母座，第二Type-A接口21为Type-A公头，从而使得上述数据线2的第二Type-A接口21能够与充电器1的第一Type-A接口11匹配连接。
当然，在具体实施中，上述第一Type-A接口11可以是公头，且上述第二Type-A接口21可以是母座，在此不作具体限定。
具体的，在本申请实施例提供的数据线2与本申请实施例提供的充电器1连接构成本申请实施例提供的充电设备时，第一Type-A接口11和第二Type-A接口21中的CC引脚、数据引脚、VBUS引脚以及GND引脚一一对应连接，具体的，第一Type-A接口11中的CC引脚与第二Type-A接口21中的CC引脚连接，第一Type-A接口11中的数据引脚与第二Type-A接口21中的数据引脚连接，第一Type-A接口11中的VBUS引脚与第二Type-A接口21中的VBUS引脚连接，第一Type-A接口11中的GND引脚与第二Type-A接口21中的GND引脚连接。
其中，在充电器1与数据线2连接的情况下，数据线2中的切换模块24基于第二Type-A接口21中的CC引脚和数据引脚上传输的电信号，控制CC走线连通或者断开；具体的，在充电设备与待充电设备连接时，若CC走线连通，则所述充电设备对待充电设备进行PD充电；若CC走线断开，则所述充电设备对待充电设备进行非PD充电。
在具体实施中，对数据线2的切换模块24基于第二Type-A接口21中的CC引脚和数据引脚上的电信号确定CC走线连通或者断开的工作原理进行以下说明：
情况一
若数据线2通过常规的充电器连接电源时，由于常规充电器的Type-A接口不具有CC引脚，从而在第二Type-A接口21中的CC引脚上不会有电流流过，从而可以据此控制CC走线断开，并通过数据引脚传输充电信号。
其中，上述常规的充电器与现有技术中具有Type-A接口的充电器结构相同，在此不再赘述。
情况二
本申请实施例提供的充电设备在与支持PD充电的非标配待充电设备连接时，第二Type-A接口21与第一Type-A接口11匹配连接，从而使第二Type-A接口21中的CC引脚上具有经目标电源121传输的电流，该电流经Type-C接口22中的CC引脚流向支持PD充电的待充电设备时，使得第二Type-A接口21中的CC引脚上检测到的电信号不同于与不支持PD充电的待充电设备时的电信号，从而可以据此控制CC走线连通，以对支持PD充电的非标配待充电设备进行PD充电。具体的，如图4所示，在数据线2的Type-C接口22还连接支持PD充电的电子设备3(例如：笔记本电脑等等)时，目标电源121传输的电流CC走线以及支持PD充电的待充电设备中的第四电阻33连接至接地端，从而使CC走线上的电压值发生改变，则充电设备基于该电压值确定与其连接的待充电设备支持PD充电，从而基于CC引脚与该待充电设备进行PD通信，以根据PD通信协议的通信内容确定PD充电参数，并据此对待充电设备进行PD充电。
情况三
本申请实施例提供的充电设备在与不支持PD充电的待充电设备(例如：常规的手机等)时，由于该不支持PD充电的待充电设备无与CC引脚以及接地端连接的第四电阻，从而使第二Type-A接口21中的CC引脚上的电压值不同于连接支持PD充电的待充电设备时的电压值，则充电设备基于该电压值确定与其连接的待充电设备不支持PD充电，进而基于数据引脚与该待充 电设备进行非PD通信，以根据数据引脚上传输的通信信号确定充电参数，并据此对待充电设备进行非PD充电。
情况四
如图4所示，本申请实施例提供的充电设备连接的电子设备3为标配的待充电设备时，该标配的待充电设备的Type-C接口中具有第三电阻31和与所述第三电阻31连接的电压源32，在数据线2上的Type-C接口22与标配的待充电设备连接时，数据引脚(图1中的D+引脚或者D-引脚)通过第三电阻31连接至电压源32，这样，能够在数据引脚上检测到与电压源32的输出电压对应的电压信号，充电设备可以据此确定与标配的待充电设备连接，从而据此控制CC走线断开，并基于数据引脚对标配的待充电设备进行预设协议的充电通信，以对标配的待充电设备进行标配充电。
情况五
本申请实施例提供的充电设备连接的待充电设备为非标配的待充电设备时，该非标配的待充电设备的Type-C接口中未设置第三电阻31和与所述第三电阻31连接的电压源32，在数据线2上的Type-C接口22与非标配的待充电设备连接时，数据引脚(图1中的D+/D-)未连接电压源，这样，能够使得数据引脚(图1中的D+/D-)上检测到的电压信号与连接标配的待充电设备时的电压信号不同，充电设备可以据此确定与非标配的待充电设备连接，从而检测第二Type-A接口21中的CC引脚上的电信号，并在根据该电信号确定与其连接的待充电设备支持PD充电时，控制CC执行连通；在根据第二Type-A接口21中的CC引脚上的电信号确定与其连接的待充电设备不支持PD充电时，控制CC走线断开。
需要说明的是，在充电设备连接的待充电设备为支持PD充电的标配待充电设备时，还可以预先设置PD充电和标配充电的优先级，以优先采用优先级别高的充电方式对支持PD充电的标配待充电设备进行充电，在该优先级别高的充电方式充电失败时，采用优先级别低的充电方式对支持PD充电的标配待充电设备进行充电，例如：若PD充电的优先级高于标配充电的优先级，则先检测第二Type-A接口21中的CC引脚上的电信号，并在确定与其连接的待充电设备支持PD充电时，控制CC走线连通，并对支持PD充电 的标配待充电设备进行PD充电；另外，在进行PD充电之后若PD充电中断或者失败，则控制CC走线断开，并检测数据引脚(图1中的D+/D-)上的电信号，并在确定与其连接的待充电设备为标配待充电设备时，基于数据引脚传输的预设通信协议的通信信号，对支持PD充电的标配待充电设备进行标配充电。
当然，在具体实施中，还可使PD充电的优先级低于标配充电的优先级，则可以先检测数据引脚(图1中的D+/D-)上的电信号，并在确定与其连接的待充电设备为标配待充电设备时，基于数据引脚传输的预设通信协议的通信信号，对标配待充电设备进行标配充电；在确定与其连接的待充电设备为非标配待充电设备时，检测第二Type-A接口21中的CC引脚上的电信号，并在确定与其连接的待充电设备支持PD充电时，控制CC走线连通，并对支持PD充电的标配待充电设备进行PD充电；在确定与其连接的待充电设备不支持PD充电时，控制CC走线断开，并基于数据引脚传输的通用通信协议的通信信号，对非标配待充电设备进行非PD充电(例如：通用协议的D+/D-充电)。
需要说明的是，在具体实施中，本申请提供的充电设备连连接电源且未与待充电设备连接时，第二Type-A接口21中的CC引脚和数据引脚(图1中的D+/D-)上的电信号值与连接待充电设备时的电信号值不相同，从而可以据此控制充电设备在未连接待充电设备时，控制CC走线断开，且充电设备不传输电源。在充电设备连接待充电设备时，根据充电通信协商的充电参数传输电源。
本申请实施例提供的数据线2，能够根据第二Type-A接口21中的CC引脚和数据引脚(图1中的D+/D-)上的电信号确定与数据线连接的充电器是否支持PD充电，且是否支持标配充电的预设通信协议，以及确定与数据线连接的待充电设备是否为支持标配的非PD充电的标配充电，且是否支持PD充电，并据此控制CC走线连通或者断开，以在CC走线连通时，对待充电设备进行PD充电；在CC走线断开时，对待充电设备进行非PD充电，从而使得具有第二Type-A接口的数据线能够支持PD充电和非PD充电。
作为一种可选的实施方式，如图4或图5所示，线缆23上还设置有第一 电阻231，切换模块24包括：控制单元241和第一开关242，第一电阻231的第一端与第二Type-A接口21中的VBUS引脚连接，第一开关242的第一端与第一电阻231的第二端连接，第一开关242的第二端与Type-C接口22中的CC引脚连接，控制单元241的输出端与第一开关242的控制端连接，控制单元241的输入端与第二Type-A接口21中的CC引脚和数据引脚分别连接；

需要说明的是，上述切换模块24除了包括上述第一开关242之外，还可以包括其他切换单元，该切换单元的控制端与MCU连接，从而可以在MCU的控制下通过该切换单元实现切换第二Type-A接口21中的CC引脚和Type-C接口22中的CC引脚之间的连接状态。
进一步的，如图4或图5所示，切换模块24还包括：第二开关243、第三开关244和第二电阻245；控制单元241的输出端还与第二开关243的控制端以及第三开关244的控制端连接，第二开关243的第一端与第二Type-A接口21中的CC引脚连接，第二开关243的第二端与第二电阻245的第一端连接，第二电阻245的第二端与第二Type-A接口21中的GND引脚连接，第三开关244的第一端与第二Type-A接口21中的CC引脚连接，第三开关244的第二端与Type-C接口22中的CC引脚连接。
在工作中，控制单元241基于第二Type-A接口21中的CC引脚和数据引脚上传输的电信号，控制第三开关244闭合且控制第一开关242和第二开关243断开，或者，控制单元241基于第二Type-A接口21中的CC引脚和 数据引脚上传输的电信号，控制第三开关244断开且控制第一开关242和第二开关243闭合。
在一种实施方式中，上述第一开关242、第二开关243以及第三开关244可以是如图4中所示的切换开关；在另一种实施方式中，上述第一开关242、第二开关243以及第三开关244可以是如图5中所示的三极管。
当然，上述第一开关242、第二开关243以及第三开关244还可以是MOS管等其他晶体管，在此并不穷举。
本实施方式中，将切换模块24设置为控制单元241和由所示控制单元241控制的第一开关242、第二开关243和第三开关244，能够简化切换模块24的结构和控制逻辑。
作为一种可选的实施方式，数据引脚包括D+引脚和D-引脚，控制单元241的输入端与所述D+引脚和所述D-引脚中的至少一个连接。
在具体实施中，充电器1中的D+引脚和D-引脚均与协议控制模块12连接，以根据D+引脚和D-引脚上传输的充电信号对待充电设备进行基于D+/D-通信协议的充电方式。且D+引脚和D-引脚中的至少一个与控制单元241的输入端连接，例如：如图4所示中，D-引脚与控制单元241的输入端连接，或者如图5所示中，D+引脚与控制单元241的输入端连接。
当然，在具体实施中，可以使D+引脚和D-引脚均与控制单元241的输入端连接。
具体的，第一Type-A接口11、第二Type-A接口21以及Type-C接口22均包括D+引脚和D-引脚，且第一Type-A接口11中的D+引脚、第二Type-A接口21中的D+引脚以及Type-C接口22中的D+引脚连通，第一Type-A接口11中的D-引脚、第二Type-A接口21中的D-引脚以及Type-C接口22中的D-引脚连通。

作为一种可选的实施方式，在本申请实施例提供的充电设备与待充电设 备连接时，若所述待充电设备为第一待充电设备，则CC走线连通；若所述待充电设备为第二待充电设备，则CC走线断开；
其中，切换模块24基于第二Type-A接口21中的CC引脚和数据引脚上传输的电信号确定所述待充电设备与所述充电设备不匹配且支持PD充电时，所述待充电设备为所述第一待充电设备；切换模块24基于第二Type-A接口21中的CC引脚和数据引脚上传输的电信号确定所述待充电设备与所述充电设备匹配或者所述待充电设备不支持PD充电时，所述待充电设备为所述第二待充电设备。
其中，所述待充电设备与所述充电设备匹配可以理解为：所述待充电设备和所述充电设备中均配置有预设通信协议，该预设通信协议的通信信号经数据引脚传输。
另外，在充电设备连接的待充电设备为非标配且不支持PD充电的待充电设备的情况下，采用经数据引脚传输的通用的DP/DM通信协议实现充电握手。
本实施方式中，对标配的待充电设备，按照经数据引脚传输的预设通信协议进行充电握手；对于非标配且支持PD充电的待充电设备，按照CC引脚传输的PD通信协议进行充电握手；对于非标配且不支持PD充电的待充电设备，按照经数据引脚传输的通用通信协议进行充电握手，从而使得本申请实施例提供的充电设备能够适用于对多种待充电设备进行充电。
作为一种可选的实施方式，在所述充电设备连接所述第一待充电设备时，切换模块24还经所述第二Type-A接口21中的CC引脚传输控制信号，所述控制信号用于控制所述充电器1在预设时间长度内停止经VBUS引脚输出电信号，并在所述充电器1经VBUS引脚输出电信号时，控制所述CC走线连通；
其中，在所述充电设备与待充电设备连接之前，所述切换模块24还控制所述CC走线断开。
在具体实施中，上述预设时间长度大于或者等于PD通信协议规定的电源间断时间。
本实施方式中，通过切换模块24传输的控制信号触发充电器1在预设时 间长度内中断VBUS引脚上传输的电信号，并在该预设时间长度后恢复供电，以在通过PD通信协议对待充电设备进行充电时，符合PD通信协议的规定的电信号间断时间，避免了在充电器1内设置控制模块以控制充电器1在预设时间长度内中断VBUS引脚上传输的电信号，而造成的使充电器1结构复杂的问题。
下面，以如图4或图5中所示的数据线2为例，对数据线2的切换模块24基于第二Type-A接口21中的CC引脚和数据引脚上的电信号将CC走线连通或者断开，的工作原理进行以下说明：
其中，如图4或图5中所示的充电器1连接电源时默认输出5V(伏特)电压，且目标电源121提供550mA(毫安)的恒定电流，第一电阻231的电阻值为56KΩ(千欧姆)，第二电阻245的电阻值为5.1KΩ。
另外，与本申请提供的充电设备匹配连接的标配待充电设备3将Type-C接口22中的数据引脚经第三电阻31连接至电压源32，该第三电阻31的电阻值为10KΩ，且该电压源32的电压值为3.3V。另外，本申请提供的充电设备与支持PD充电的待充电设备连接时，Type-C接口22中的CC引脚还通过第四电阻33连接至接地端，该第四电阻33的电阻值为5.1KΩ。
情况一
若在数据引脚(D+引脚或者D-引脚)上检测到3.3V电压，则确定本申请实施例提供的充电设备与标配的待充电设备连接，且已经通过D+引脚和D-引脚上传输的DP/DM通信信号完成充电握手，此时切换模块24可以控制CC走线断开。
情况二
若在第二Type-A接口21中的CC引脚上检测到1.68V电压，则切换模块24确定与数据线2连接的充电器(具体可以是如图4或图5中所示充电器1)和待充电设备均支持PD充电，从而在该待充电设备未通过DP/DM通信信号完成充电握手的情况下，切换模块24可以连通CC走线。
情况三
若在第二Type-A接口21中的CC引脚上检测到1.98V电压，则切换模块24确定数据线2连接的充电器为支持PD充电且与数据线2匹配的充电器 (具体可以是如图4或图5中所示充电器1)，且未连接待充电设备，此时切换模块24可以断开CC走线。
情况四
若在第二Type-A接口21中的CC引脚上检测到0.4V电压，则切换模块24确定数据线2连接的充电器为不支持PD充电的充电器或者与数据线2不匹配的充电器，此时切换模块24可以断开CC走线。
另外，在断开CC走线的同时，还可以断开如图4中所示的第二开关243。
需要说明的是，在实际应用中，上述第一电阻和第二电阻的电阻值、上述电流源输出的电流值、上述电压源输出的电压值等可以与上述参数不一致，仅需根据第二Type-A接口21中的CC引脚上检测到的电信号值和数据引脚上检测到的电信号值能够区分充电器和待充电设备是否支持PD充电，以及待充电设备是否为标配的待充电设备即可，在此不作具体限定。
另外，如图6所示，在上述数据引脚为D+引脚和D-引脚的情况下，第一Type-A接口11的第一侧设置有GND引脚、D+引脚、D-引脚以及VBUS引脚，该第一Type-A接口11的第二侧设置有CC引脚，上述第一Type-A接口11的第一侧与第二侧为相对的两侧。
相应的，如图7所示，第二Type-A接口21的第三侧设置有GND引脚、D+引脚、D-引脚以及VBUS引脚，该第二Type-A接口21的第四侧设置有CC引脚，上述第二Type-A接口21的第三侧与第四侧为相对的两侧。且在第一Type-A接口11与第二Type-A接口21连接时，第一Type-A接口11和第二Type-A接口21中的GND引脚对应连接，D+引脚对应连接，D-引脚对应连接，VBUS引脚对应连接，且CC引脚与CC引脚连接。
这样，上述GND引脚、D+引脚、D-引脚以及VBUS引脚的分布位置与现有技术中的Type-A接口中的GND引脚、D+引脚、D-引脚以及VBUS引脚的分布位置相同，从而能够与常规的Type-A接口匹配连接，以实现GND引脚、D+引脚、D-引脚以及VBUS引脚的常规功能，使得本申请实施例提供的充电器1能够与具有常规的Type-A接口的数据线连接，且本申请实施例提供的数据线2能够与具有常规的Type-A接口的充电器连接。
需要说明的是，上述第一Type-A接口11中各引脚的分布位置还可以交 换或者改变，在此不作具体限定，另外，进行非PD充电过程中，第一Type-A接口11中的VBUS引脚、GND引脚、D+引脚以及D-引脚的结构和工作原理与现有技术中的第一Type-A接口11中的VBUS引脚、GND引脚、D+引脚以及D-引脚的结构和工作原理相同，在此不再具体阐述。

步骤805、判断充电设备是否连接第二预设待充电设备。
在具体实施中，上述第二预设待充电设备可以是支持PD充电的笔记本电脑等，在此不作具体限定。
另外，在步骤805的判断结果为“是”的情况下执行步骤807，在步805的判断结果为“否”的情况下重复执行步骤802。
