一种电子设备及硬件地址配置方法
相关申请的交叉引用
本申请要求在2019年09月23日提交中国专利局、申请号为201910900517.9、申请名称为“一种电子设备及硬件地址配置方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子科学技术领域，尤其涉及一种电子设备及硬件地址配置方法。
背景技术
随着电子市场的发展，大多数电子设备都具备了多路输出的功能。一般来说，电子设备中具有多个输出电路，不同的输出电路可以具有相同或不同的输出路径，能够向相同或不同的输出路径输出信号。
当前的电子设备中的控制电路可以通过一条通信总线控制多个输出电路，上述多个输出电路中分别配置有具有唯一性的硬件地址，使控制电路可以独立控制各个输出电路。通常，为输出电路配置硬件地址的配置规则存在多种形式，但大多数配置规则都要求为任一输出电路配置的硬件地址需要与该输出电路的输出路径存在一定的对应关系。
目前，输出电路的硬件地址多是通过人工手动配置的。例如，硬件地址共有K位，输出电路的前面板上设置有K个拨号开关，K个拨号开关与硬件地址的K位一一对应。操作人员在安装输出电路时，首先根据硬件地址配置规则和输出电路对应的输出路径，确定该输出电路的硬件地址，之后，分别开启或关闭上述K个拨号开关，使K个拨号开关的开关状态可以表征K位硬件地址。例如，第一个拨号开关对应硬件地址第一位，第一个拨号开关开启时表示硬件地址的第一位取值为“1”，第一个拨号开关关闭时表示硬件地址的第一位取值为“0”。在输出电路上电后，输出电路可以自行读取前面板上K个拨号开关的开启或关闭状态，从而得到并存储自身的硬件地址。
然而，通过人工手动配置硬件地址的实现方式较为繁琐，对维护人员要求较高，且容易出现操作失误。
发明内容
有鉴于此，本申请实施例提供一种电子设备及硬件地址配置方法，电子设备内部的控制电路可以自行为各个输出电路配置硬件地址，既有利于减少维护成本，又有利于提高电子设备的可靠性，还有利于降低电子设备的成本。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
多路输出是电子设备中的常见功能，电子设备可以从多个输出端口同时输出多个信号。例如可以同时给多辆电动汽车充电的多枪电动汽车充电桩、可以同时给多个终端充电的多插头充电器等设备都可以实现多路输出。需要指出的是，在本申请实施例中，信号可以为电信号，例如信号可以是电流、电压等等，信号可以是用于传递信息的通信信号，也可以是用于提供电能的充电信号，本申请实施例对此并不多作限制。
以下实施例中的具体操作方法也可以应用于装置实施例或系统实施例中。需要说明的是，在本申请的描述中“至少一个”是指一个或多个，其中，多个是指两个或两个以上。鉴于此，本发明实施例中也可以将“多个”理解为“至少两个”。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
需要指出的是，本申请中“耦合”指的是能量传递关系，具体来说，可以是电能。例如，“A与B”耦合指的是A与B之间可以互相传递电能，也可以理解为，A与B之间可以互相传递电荷。反应在电连接关系上，便可以是A与B之间直接电连接，或者也可以是A与B之间通过其它导体或电子器件间接电连接，从而使得A与B之间可以互相传递电能。
图1示例性示出了一种能够实现多路输出的电子设备结构示意图，如图1所示，电子设备主要包括控制电路101、N个输出电路(输出电路1、输出电路2、……、输出电路N)和M个输出导线(输出导线1、……、输出导线M)，N和M皆为大于1的整数。
图1中，每个输出电路都可以输出信号，具体来说，输出电路可以包括内部电源，该内部电源可以用于为输出电路提供电能，输出电路可以对内部电源提供的电能作进一步处理，从而输出信号，输出电路也可以与位于电子设备之外的外部电源耦合，接收外部电源提供的电能，还可以对外部电源提供的电能作进一步处理，从而输出信号。需要指出的是，输出电路的具体实现形式与电子设备的类型、功能相关，本申请实施例对此并不多作限制。
示例性的，图1所示的电子设备可以为一种多枪式电动汽车充电桩。电动汽车充电桩还包括输入导线103，N个输出电路的输入端可以通过输入导线103并联。输入导线103也可以称为交流输入母线，输入导线103还与电动汽车充电桩外部的交流电源耦合，可以接收交流电源提供的交流电。可选地，电动汽车充电桩的每个输出电路中皆可以包括交流-直流转换器，使得每个输出电路皆可以将通过输入导线103接收到的交流电转换为直流电，从而可以输出直流电形式的输出信号，电动汽车充电桩输出的信号也可以称为充电电流(充电电压)。
输出导线也可以称为直流输出母线。如图1所示，输出导线1至M与输出电路1至N之间为一对多的对应关系，即M个输出导线中，每个输出导线与N个输出电路中的一个或多个输出电路的输出端耦合，且，N个输出电路中，每个输出电路的输出端只与M个输 出导线中的一个输出导线耦合。在N个输出电路中，每个输出电路可以分别向与其耦合的输出导线输出信号。
在M个输出导线中，每个输出导线皆可以接收与其耦合的一个或多个输出电路的输出信号，并将接收到的总输出信号输出电子设备。其中，总输出信号可以包括与该输出导线耦合的一个或多个输出电路各自的输出信号，在该一个或多个输出电路同时输出时，该总输出信号还可以是一个或多个输出电路各自的输出信号构成的混合信号。例如图1中，输出导线1传输的总输出信号实际为输出电路1、输出电路2和输出电路3中一个或多个输出电路输出的充电电流的混合电流。
例如，当只有输出电路1输出充电电流，且输出电路2和输出电路3不输出充电电流时，总输出信号中只包括输出电路1输出的充电电流，当输出电路1和输出电路2同时输出充电电流，且输出电路3不输出充电电流时，总输出信号中包括输出电路1的充电电流和输出电路2的充电电流构成的混合电流，当输出电路1、输出电路2和输出电路3同时输出充电电流时，总输出信号中包括输出电路1的充电电流、输出电路2的充电电流和输出电路3的充电电流构成的混合电流。
在一种可能的实现方式中，如图1所示，M个输出导线中每个输出导线还可以对应一个输出路径，输出导线可以向对应的输出路径传输总输出信号，输出路径可以对接收到的总输出信号作进一步处理。示例性的，图1中输出导线1对应有输出路径1，输出路径1中可以包括放大器、滤波器等功能器件，使得输出路径1可以对输出导线1传输的输出信号进行放大、滤波等处理后，再输出至电子设备外部。可以理解，对于不同类型和/或不同功能的电子设备，输出路径的具体实现存在多种可能，本申请实施例对此并不多作限定。
以电动汽车充电桩为例，如图1所示，每个输出路径中还可以包括一个充电枪，图1所示的电动汽车充电桩为M枪电动汽车充电桩，能够同时最多为M辆电动汽车充电。以充电枪1为例，操作人员在对电动汽车充电时，可以将充电枪1插入待充电的电动汽车的充电口，输出导线1传输的总输出信号(充电电流)经充电枪1输出至电动汽车，从而为电动汽车提供充电电流。
如图1所示，多路输出的电子设备中往往安装有多个输出电路，每个输出电路的控制端皆与控制电路101耦合，控制电路101可以分别控制各个输出电路的工作状态。一般来说，控制电路101可以是安装有可执行程序的处理器芯片，在电子设备工作过程中，控制电路101可以运行其内部的可执行程序，生成控制指令，并通过控制指令控制电子设备中各个输出电路的工作状态。示例性的，控制电路101可以控制输出电路A的工作状态，也可以理解为，控制电路101可以控制输出电路A的开启或关闭，以及，控制电路101还可以控制输出电路A的输出功率、输出电流的电流值、输出电压的电压值等等，本申请实施例对此并不多作限制。
在一种可能的实现方式中，为了节省控制电路101的端口占用，输出电路1至N的控制端并联，并通过通信总线102与控制电路101耦合，在此情况下，只占用了控制电路101中与通信总线102耦合的端口来实现对输出电路1至N的控制，大大降低了占用控制电路101的端口的数量。其中，通信总线102可以是外设部件互连标准(peripheral component interconnect，PCI)总线扩展工业标准结构(extended industry standard architecture，EISA)总线、控制器局域网络(controller area network，CAN)等。通信总线102可以分为地址总线、数据总线、控制总线等。为便于表示，本申请实施例中仅用一条线表示，但并不表示仅有 一根总线或一种类型的总线。
在一种可能的实现方式中，电子设备处于工作过程时，控制电路101可以向通信总线102发送第一控制指令，分别控制各个输出电路的工作状态，从而可以调整各个输出导线所传输的总输出信号。具体来说，输出电路1至N中皆配置有具有唯一性的硬件地址，即输出电路1至N中任两个输出电路的硬件地址皆不相同。通常，输出电路的硬件地址与该输出电路所耦合的输出导线之间存在对应关系，以图1为例，输出电路1的硬件地址、输出电路2的硬件地址和输出电路3的硬件地址皆与输出导线1对应。在此情况下，每个输出电路的硬件地址便可以表示该输出电路与任一输出导线之间的耦合关系，控制电路101便可以从待调整的输出导线对应的一个或多个硬件地址中，确定出一个或多个硬件地址作为目标硬件地址，并通过该一个或多个目标硬件地址调整对应的一个或多个输出电路的输出情况，从而可以调整输出导线的总输出信号。
其中，待调整的输出导线可以是需要调整总数才信号的输出功率的传输导线，或者也可以是开启或停止总输出信号的输出导线。示例性的，假设控制电路101需要调整输出导线1所传输的总输出信号的功率，在此情况下，控制电路101可以确定输出导线1对应的硬件地址为硬件地址1、硬件地址2和硬件地址3，其中，硬件地址1为输出电路1的硬件地址，硬件地址2为输出电路2的硬件地址，硬件地址3为输出电路3的硬件地址。控制电路101可以从硬件地址1、硬件地址2和硬件地址3中确定一个或多个硬件地址作为目标硬件地址。
继而，控制电路101可以向通信总线102发送第一控制指令，该第一控制指令中可以包括一个或多个目标硬件地址，以及控制信息。通信总线102传输该第一控制指令，由于输出电路1至N的控制端并联，因此输出电路1至N皆可以接收到该第一控制指令。针对输出电路1至N中的每一个输出电路，输出电路判断第一控制指令中的一个或多个目标硬件地址内是否包括自身的硬件地址，若是，则输出电路执行该第一控制指令中的控制信息，若否，则输出电路可以忽略该第一控制指令，也就是说该输出电路并不会执行该第一控制指令中的控制信息。
示例性的，假设第一控制指令中包括目标硬件地址(硬件地址1)，以及控制信息(“开启”)，则对于输出电路2至N而言，由于第一控制指令的一个或多个目标硬件地址中不包括输出电路自身的硬件地址，因此输出电路2至N可以忽略该第一控制指令。对于输出电路1而言，第一控制指令的一个或多个目标硬件地址中包括自身的硬件地址，则输出电路1执行第一控制指令中的控制信息，即输出电路1开启向输出导线1输出信号。
一般来说，控制信息可以包括开启、关闭、增大输出功率、减小输出功率等等多种可能的类型，本申请实施例对此并不多作限定。控制电路101可以根据调整需求选择合适的控制信息。示例性的，若需要增大输出导线1所传输的总输出信号的功率，则控制电路101可以选择“开启”类型的控制信息，以增加为输出导线1提供输出信号的输出电路从而增大输出导线1所传输的总输出信号的功率，控制电路101也可以选择“增大输出功率”类型的控制信息，以增大与输出导线1耦合的一个或多个输出电路的输出功率，从而增大输出导线1所传输的总输出信号的功率。
由上述过程可见，控制电路101是通过硬件地址实现对各个输出电路的单独控制的。目前，输出电路的硬件地址多需通过人工手动配置。以电动汽车充电桩为例，图2示例性示出了一种输出电路前面板示意图。如图2所示，输出电路的前面板上设置有8个拨号开 关，该8个拨号开关可以表征8位的硬件地址，且8个拨号开关与硬件地址的8位数值之间一一对应。
操作人员在安装输出电路时，首先根据硬件地址配置规则和输出电路对应的输出导线，确定该输出电路的硬件地址，之后，分别开启或关闭前面板上的8个拨号开关，使8个拨号开关的开关状态可以表征为该输出电路配置的8位硬件地址。例如，图2中的8个开关按从左到右的顺序分别对应硬件地址的第一至第八位数值，且开关开启状态表示对应的硬件地址位数值为“1”，开关关闭状态表示对应的硬件地址位数值为“0”，图2中第一个开关、第四个开关和第六个开关为开启状态，其它开关为关闭状态，则可以表示硬件地址10010100。在输出电路上电后，输出电路便可以自行读取前面板上8个拨号开关的开启或关闭状态，从而得到并存储自身的硬件地址。
然而，人工手动配置硬件地址的操作过程较为繁琐，对维护人员要求较高，且容易出现操作失误，有鉴于此，本申请实施例提供一种硬件地址的配置方法及电子设备，控制电路101可以为各个输出电路配置硬件地址，从而省去人工手动配置硬件地址的过程。接下来，以电动汽车充电桩为例，对本申请实施例所提供的技术方案作进一步说明。可以理解，其它类型的多路输出电子设备也可以适用本技术方案，其具体实现可以参考接下来的实施例，本申请实施例对其不再多作赘述。
本申请实施例一提供一种电子设备。请参考图1所示的电动汽车充电桩，控制模块101可以在电动汽车充电桩上电后，执行一次或多次硬件地址分配操作。每执行一次硬件地址分配操作，可以为一个输出电路分配硬件地址。接下来，以输出电路i为例，对本申请实施例中的硬件地址分配操作进行进一步说明。其中，输出电路i为输出电路1至N中的任一输出电路，也可以理解为，i取值为[1,N]中的任一整数。
控制电路101可以在上电后按照如图3所示的方法为其中任一输出电路(输出电路i)配置硬件地址。如图3所示，主要包括以下步骤：
S301：控制电路101开启输出电路i。具体来说，控制电路101可以通过通信总线102向N个输出电路发送第二控制指令，该第二控制指令中包括输出电路i的生产序列号。
在电动汽车充电桩上电后，各个输出电路可以广播自身的标识信息，如各个输出电路分别广播自身的生产序列号，从而使控制电路101可以接收到各个输出电路的生产序列号。一般来说，输出电路的生产序列号可以是在输出电路生产过程中烧录在输出电路内部的，可以标识出输出电路的生产批次、生产厂商等多种信息。生产序列号具有唯一性，即一个输出电路对应一个生产序列号，电动汽车充电桩中的各个输出电路在上电后广播生产序列号，使得控制电路101可以根据接收到的生产序列号识别出电动汽车充电桩中所安装的各个输出电路，也可以理解为，控制电路101可以根据接收到的生产序列号识别出电动汽车充电桩中存在哪几个输出电路。接下来以输出电路的标识信息为生产序列号为例进行说明。
在一种可能的实现方式中，控制电路101可以依次为输出电路1至N配置硬件地址，也就是i从“1”开始取值，并依次取值至“N”，也可以理解为i取遍[1,N]中的整数。需要指出的是，本申请实施例中i的不同取值仅为了在表述上区别不同的输出电路，并不代表在实际应用中，不同输出电路之间存在不同取值的“i”。以下变量“j”、“h”等皆同，不再赘述。
在另一种可能的实现方式中，控制电路101和输出电路1至N中皆包括非掉电易失性 存储器，如带电可擦可编程只读存储器(electrically erasable programmable read only memory，EEPROM)。在此情况下，控制电路101可以在该非掉电易失性存储器中存储已配置过硬件地址的输出电路的生产序列号，输出电路1至N可以在该非掉电易失性存储器中存储被配置的硬件地址。在此情况下，控制电路101在接收到任一输出电路广播的生产序列号后，执行S301之前，可以根据所存储的生产序列号判断是否已为该生产序列号对应的输出电路配置了硬件地址。示例性的，若该输出电路为新安装的输出电路，控制电路101便未存储该输出电路的标识信息，也就是说，控制电路101已存储的标识信息中不包括该输出电路的标识信息，因此控制电路101需要为新安装的输出电路配置硬件地址。
示例性的，控制电路101在接收到输出电路i的生产序列号后，可以先判断是否已存储有输出电路i的生产序列号。若已经存储有输出电路i的生产序列号，则说明已为输出电路i配置了硬件地址，因此无需再执行图3所示的配置过程。若未存储有输出电路i的生产序列号，则说明输出电路i为新安装入电动汽车充电桩的输出电路，在此情况下，控制电路101可以继续执行S301，并存储输出电路i的硬件地址。在下一次上电后，控制电路101便可以根据已存储的生产序列号确定已为输出电路i配置了硬件地址，无需再次为输出电路i配置硬件地址。
如图1所示，输出电路1至N中皆可以包括接收器，使得输出电路1至N皆可以接收到该第二控制指令。输出电路i接收到第二控制指令后，确定第二控制指令中的生产序列号为自身的生成序列号，因此输出电路i根据第二控制指令开启输出信号。对于输出电路1至N中除输出电路i之外的每一个输出电路，在接收到第二控制指令后，可以确定第二控制指令中的生产序列号并非自身的生成序列号，因此可以忽略该第二控制指令，即不输出信号。
S302：控制电路101确定输出电路i对应的输出导线j。
其中，输出导线j为输出导线1至M中与输出电路i耦合的输出导线，由于i取值为[1,N]中的任一整数，因此j取值也可以为[1,M]中的任一整数。需要指出的是，输出电路i与输出导线j之间的耦合关系是操作人员预先设定好的。其中，“预先设定”可以理解为，对于控制电路101来说，输出电路i与输出导线j之间的耦合关系是客观存在的，只有操作人员进行拆卸或安装操作才可以改变输出电路i与输出导线j之间的耦合关系。对于控制电路101而言，在不考虑操作人员人为输入输出电路i与输出电路j之间的耦合关系的情况下，控制电路101在为输出电路i分配硬件地址之前，通常并不知晓输出电路i与输出电路j之间的耦合关系，也就是说，控制电路101并不知晓任一输出电路具体与哪一个输出导线耦合，因此控制电路101需要先确定输出电路i与哪一个输出导线耦合。
如图1所示，控制电路101包括M个检测端口，该M个检测端口分别与M个输出导线一一对应耦合，控制电路101可以在发送第二控制指令后，通过M个检测端口分别检测M个输出导线各自传输的总输出信号。由于第二控制指令只会开启输出电路i输出信号，因此只有与输出电路i耦合的输出导线j才会有总输出信号传输，且该总输出信号实际为输出电路i的输出信号。
在此情况下，控制电路101的M个检测端口中，与输出导线j耦合的检测端口j可以检测到高压输入，其它检测端口则可以检测到低压输入(或无输入)，因此控制电路101可以确定输出电路i的输出端与输出导线j耦合。
在一种可能的实现方式中，第二控制指令可以控制输出电路i以较小的输出电压输出 信号，以保护控制电路101不受高压损坏。例如，可以通过第二控制指示输出电路i输出电压值为200V的输出信号。
在本申请实施例中，控制电路101与各个输出导线之间可以直接电连接，也可以间接电连接。在一种可能的实现方式中，如图1所示，电动汽车充电桩中还可以包括检测电路104，也就是说，控制电路101与各个输出导线之间通过检测电路104间接电连接。检测电路104包括M个一一对应的输入端和输出端，其中，M个输入端分别与M个输出导线一一对应耦合，M个输出端分别与控制电路的M个检测端口耦合。示例性的，检测端口的输入端j与输出导线j耦合，输出端j与控制电路101的检测端口j耦合。检测电路可以通过输入端j检测输出导线j传输的总输出信号，并对该总输出信号按照一定的分压比例进行分压处理，将分压处理后的总输出信号通过输出端j提供给控制电路的检测端口j。
具体来说，检测电路104可以包括M个互相独立的分压电路。如图4所示，输入端1与输出端1之间的分压电路包括分压电阻R1a和分压电阻R1b，输入端j与输出端j之间的分压电路包括分压电阻Rja和分压电阻Rjb，输入端M与输出端M之间的分压电路包括分压电阻RMa和分压电阻RMb，不同分压电路中分压电阻的连接方式相同，接下来以输入端j与输出端j之间的分压电路为例进行说明，其它分压电路不再赘述。
如图4所示，分压电阻Rja的一端通过输入端j与输出导线j耦合，分压电阻Rja的另一端与分压电阻Rjb的一端耦合，分压电阻Rjb的另一端接地，在Rja的另一端与Rjb的一端之间，存在一连接点通过输出端j与控制电路的检测端口j耦合。分压电阻Rja和分压电阻Rjb构成的分压电路可以按照一定的分压比例，对输入端j检测到的输出导线j的总输出信号进行分压处理，该分压处理可以如以下公式一所示：
Figure PCTCN2020095953-appb-000001
其中，r ja为分压电阻Rja的阻值，r jb为分压电阻Rjb的阻值，V j为输出导线j的总输出信号的电压值，V′ j为分压处理后输出导线j的总输出信号的电压值。
S303：控制电路101根据配置规则，为输出电路i分配与输出导线j对应的硬件地址。如前所述，为输出电路i分配的硬件地址需要与输出导线j满足对应关系，该对应关系便为配置规则。在一种可能的实现方式中，该配置规则可以表述为M个输出导线与M个硬件地址范围之间的对应关系，更进一步的，该M个硬件地址范围可以互不重叠。示例性的，该配置规则可以如下表一所示：
表一
输出导线 硬件地址范围
1 [1,10]
2 [11,20]
…… ……
M [(M-1)×10+1，M×10]
如表一所示，输出导线1至M分别对应有不同的硬件地址范围，需要指出的是，上述硬件地址为十进制表示形式，在具体实现过程中，控制电路101也可以在为输出电路i分配好硬件地址后，将为输出电路i分配的硬件地址转换为二进制表示形式，并将二进制形式的硬件地址发送给输出电路i，或者也可以在控制电路101中直接设置二进制形式的硬件地址范围，本申请实施例对此并不多作限制。
基于表一所示的对应关系，假设输出导线j为图1中输出导线1，输出电路i为图1中的输出电路2，控制电路101在确定输出电路2与输出导线1耦合之后，根据表一所示的配置规则确定输出导线1对应的硬件地址范围为[1,10]。控制电路101进而可以从硬件地址范围[1,10]中确定一未被分配的硬件地址，如硬件地址“2”作为输出电路2的硬件地址。在一种可能的实现方式中，控制电路101可以按照由小到大的顺序依次为与输出导线1耦合的输出电路分配地址，示例性的，在为输出电路2确定硬件地址时，可以从未被分配的硬件地址中确定取值最小的硬件地址分配给输出电路2。
S304：控制电路101向输出电路i发送配置信息，该配置信息用于指示为输出电路i分配的硬件地址。
具体来说，该配置信息也可以通过配置指令的形式发送。例如，配置指令中包括输出电路i的生产序列号和配置信息，输出电路1至N皆可以接收到该配置指令。但只有输出电路i的生产序列号可以匹配配置指令中的生产序列号，因此只有输出电路i可以执行配置信息。也就是说，输出电路i可以根据配置信息获得控制电路101为其分配的硬件地址，并存储该硬件地址。在一种可能的实现方式中，该配置指令还可以指示输出电路i关闭，从而停止输出信号。具体来说，该配置指令中可以携带指示输出电路i关闭的控制信息(“关闭”)，也可以由输出电路i默认在接收到配置信息后关闭，本申请实施例对此并不多作限制。
至此，便完成了为输出电路i配置硬件地址。
接下来，本申请实施例二还提供一种控制电路101依次为输出电路1至N配置硬件地址的可能的实现方式，如图5所示，主要包括以下步骤：
S501：控制电路101启动识别。一般在电动汽车充电桩上电后，控制单元101便可以自动启动识别。当然，也可以由操作人员手动触发启动识别，本申请实施例对此并不多作限制。在识别过程中，控制电路101可以识别各个输出电路发送的生产序列号。
S502：控制电路101开启第k个生产序列号对应的输出电路。具体来说，控制电路101可以按照预设的执行顺序多次执行硬件地址分配操作，从而依次为各个输出电路分配硬件地址。示例性的，控制电路101可以在获得N个输出电路的生成序列号后，按照执行顺序排列各个输出电路的生产序列号，并根据排序结果依次开启各个生产序列号对应的输出电路，从而分别为N个输出电路分配硬件地址。其中，执行顺序可以是按照生产序列号由小到大、由大到小，也可以是按照控制电路101接收到各个输出电路的生产序列号的先后顺序等等，本申请实施例对此并不多作限制。如图5中，控制电路101最先开启第1个生产序列号对应的输出电路，也即k＝1。
S503：控制电路101分别检测输出导线1至M各自的总输出信号。
S504：控制电路101确定第k个生产序列号对应的输出电路所耦合的输出导线h。
S505：控制电路101关闭第k个生产序列号对应的输出电路，并为第k个生产序列号对应的输出电路分配与输出导线h对应的硬件地址。
S502至S505的具体实现方式可以参考上述实施例一所提供的硬件地址分配操作，对此不再赘述。
如图1所示，电动汽车充电桩中还包括放电电路105。放电电路105的输入端分别与输出导线1至N耦合，放电电路105的控制端与控制电路101耦合，放电电路105中包括 接地电路，可以向地释放输出导线1至M中的残留电荷。
有鉴于此，如图5，本方法还包括S506：控制电路101开启放电电路105，并检测输出导线h的总输出信号。
S507：控制电路101判断输出导线h的总输出信号的电压值是否低于预设阈值，若是，则继续执行S508，若否，则返回S506。可以理解，连续执行的S506之间可以间隔一定时延，本申请实施例对此并不多作限制。
S508：控制电路101关闭放电电路105，并判断当前k的取值是否大于N。若是，则执行S511，结束配置硬件地址的过程。若否，则继续执行S509。
S509：电路更新，k的取值加1，即继续为第k+1个生产序列号对应的输出电路配置硬件地址，在接下来的配置过程中，k的取值加1，即k＝k+1。
S510：开启第k个生产序列号对应的输出电路，返回并继续执行S503。
需要指出的是，在S509之后，S510之前，控制电路101还可以判断已存储的生产序列号中是否包括该第k个生产序列号，若否，则继续执行S510，若是，则可以返回并继续执行S508。在此情况下，在接下来执行S508时，可以不执行关闭放电电路105的操作。
与之类似，在S502之前，也可以先判断已存储的生产序列号中是否包括该第1个生产序列号，若否，则继续执行S502，若是，则可以直接执行S509。
本申请实施例三提供另一种电子设备。图1所示的电动汽车充电桩中，输出电路与输出导线之间为固定耦合方式，即输出电路和输出导线之间的耦合方式是固定的，在电动汽车充电桩工作过程中，输出电路和输出导线之间的耦合关系并不会发生变化。
为了适应不同的应用需求，还存在另一种可能的耦合方式—柔性耦合。如图6所示，为本申请实施例三提供的另一种电子设备结构示意图，该电子设备也为多路输出的电子设备。示例性的，图6所示的电子设备也可以作为电动汽车充电桩。如图6所示，电子设备包括控制电路101、N个输出电路(输出电路1至N)，N个开关电路(开关电路K1至KN)，M个输出导线(输出导线1至M)。
其中，输出电路1至N的控制端通过通信总线102并联，并与控制电路101耦合。输出电路1至N的具体实现形式、控制电路101的具体实现形式、控制电路101对输出电路1至N的控制方式等方面皆与图1所示的电子设备类似，对此不再赘述。
图6中，N个开关电路的控制端分别与控制电路101耦合，N个开关电路的输入端与N个输出电路的输出端分别一一对应耦合，也可以表述为，输出电路i的输出端与开关电路Ki的输入端耦合，其中，i的取值为[1,N]中的任一整数，或者，i取遍[1,N]中的整数。N个开关电路中，每个开关电路的输出端皆可以与M个输出导线耦合，也就是说，开关电路Ki包括M个输出端，且M个输出端分别与M个输出导线一一对应耦合，开关电路Ki可以在控制电路101的控制下，导通输出电路i与M个输出导线中任一输出导线之间的传输路径。在本申请实施例中，开关电路可以是继电器、开关晶体管等开关器件或开关电路，对此并不多作限定。
在图6所示的电子设备中，每个输出电路也配置有具有唯一性的硬件地址，即输出电路1至N中任两个输出电路的硬件地址皆不相同。且，输出电路的硬件地址与该输出电路所耦合的开关电路之间存在对应关系。例如图6中，输出电路1的硬件地址与开关电路K1对应，输出电路2的硬件地址与开关电路K2对应。在此情况下，每个输出电路的硬件地 址便可以表示该输出电路与开关电路之间的耦合关系，控制电路101便可以采用以下方法调整目标输出导线的总输出信号，包括：
步骤一：控制电路101确定待调整的目标输出导线的一个或多个目标开关电路。例如，目标输出导线为输出导线1，即控制电路101需要调整输出导线1的总输出信号。在此情况下，控制电路101可以根据调整需求，控制一个或多个开关单元导通或断开对应的输出电路与输出导线1之间的传输路径。示例性的，假设需要增大输出导线1的总输出信号的功率，则可以控制部分开关单元导通对应的输出电路与输出导线1的传输路径，增加向输出导线1传输输出信号的输出电路的数量，从而增大输出导线1的总输出功率。
步骤二：控制电路101根据配置规则，确定一个或多个目标开关电路分别对应的一个或多个硬件地址。其中，配置规则便是为输出电路配置硬件地址的规则，可以指示硬件地址与开关电路之间的对应关系。基于配置规则，便可以确定一个或多个目标开关电路分别对应的一个或多个硬件地址。
步骤三：控制电路101通过通信总线向N个输出电路发送第三控制指令，和/或，向一个或多个目标开关电路发送第四控制指令。
其中，第三控制指令与实施例一中的第一控制指令类似，对此不再赘述。
第四控制指令用于指示目标开关电路断开或导通输出信号与待调整的目标输出导线之间的传输路径。示例性的，以开关电路Ki为例，第四控制指令中可以包括开关电路Ki的M个输出端中，与目标输出导线耦合的输出端的标识信息，开关电路Ki可以根据第四控制指令中的标识信息连通对应输出端，从而导通输出电路i与目标输出导线之间的传输路径。
可以理解，控制电路101在调整目标输出导线的总输出信号的时候，既有可能只调整一个或多个目标输出电路的工作状态(如增大或减小一个或多个目标输出电路的输出功率)，也可以只控制目标开关电路(如断开目标开关电路与目标输出导线之间的传输路径)，也可以既调整一个或多个目标输出电路的工作状态，又控制目标开关电路(如断开目标开关电路与目标输出导线之间的传输路径的同时关闭目标开关电路)，在具体应用过程中可以根据调整需求灵活选择，本申请实施例对此不再一一列举。
由上述过程可见，采用柔性耦合的耦合方式，可以使控制电路101更为灵活地调整各个输出导线的总输出信号。但控制电路101对各个输出电路的控制依旧依赖于硬件地址。有鉴于此，本申请实施例还提供一种硬件地址配置方法，控制电路101可以为各个输出电路配置硬件地址，从而省去人工手动配置硬件地址的过程。接下来，以电动汽车充电桩为例，对本申请实施例所提供的技术方案作进一步说明。可以理解，其它类型的采用柔性连接方式的多路输出电子设备也可以适用本技术方案，其具体实现可以参考接下来的实施例，本申请实施例对其不再多作赘述。
控制电路101可以在上电后按照如图7所示的方法为其中任一输出电路配置硬件地址。如图7所示，主要包括以下步骤：
S701：控制电路101开启输出电路i。具体实现方式可以参考S301，对此不再赘述。
S702：控制电路101确定输出电路i对应的开关电路Ki。
需要指出的是，输出电路i与开关电路Ki之间的耦合关系是预先设定的，也就是客观存在的，只有操作人员进行拆卸或安装操作才可以改变输出电路i与开关电路Ki之间的耦合关系。对于控制电路101而言，在不考虑操作人员人为输入输出电路i与开关电路Ki 之间的耦合关系的情况下，控制电路101在为输出电路i分配硬件地址之前，通常并不知晓输出电路i与开关电路Ki之间的耦合关系，因此控制电路101需要先确定输出电路i与哪一个开关电路耦合。
如图6所示，控制电路101还与M个输出导线中的检测导线(输出导线1)耦合，控制电路101可以检测检测导线上的总输出信号。需要指出的是，输出导线1作为检测导线仅为一具体示例，在具体实现过程中，M个输出导线中的任一输出导线都可以作为检测导线。
在S702的具体实施过程中，控制电路101可以依次控制N个开关电路导通向检测导线的传输路径，在接收到检测导线传输的总输出信号后，确定在接收到总输出信号之前，最后开启的开关电路为输出电路i对应的开关电路Ki。此时，检测导线传输的总输出信号实际上为输出电路i的输出信号。
控制电路101依次控制N个开关电路导通向检测导线(输出导线1)的传输路径。对于除开关电路Ki之外的每一个开关电路，控制电路101在控制开关电路导通向检测导线的传输路径后，由于除输出电路i之外的其它输出电路都为关闭状态，因此检测导线上不会有输出信号传输，控制电路101会在检测导线上检测到低压输入(或无输入)。如图8所示，控制电路101在控制开关电路Ki导通检测导线(输出导线1)的传输路径后，输出电路i的输出信号可以经开关电路Ki输出至检测导线，此时，控制电路101便可以在检测导线上检测到高压输入，控制电路101进而便可以确定最后开启的开关电路为输出电路i对应的开关电路Ki。
与实施例一类似，为了保护控制电路101不受高压损坏，控制电路101可以控制输出电路i以较小的输出电压输出信号，例如，可以控制输出电路i输出电压值为200V的输出信号。
在本申请实施例中，控制电路101与检测导线之间可以直接电连接，也可以间接电连接。如图6和图8所示，还可以在控制电路101和检测导线之间设置检测电路104，也就是说，控制电路101和检测导线通过检测电路104间接电连接。检测电路104的输入端与检测导线耦合，检测电路104的输出端与控制电路101耦合。检测电路104可以对检测导线的总输出信号进行分压处理，并将分压处理后的总输出信号提供给控制电路101。具体来说，检测电路104可以包括一个分压电路，例如，可以是如图4中Rja与Rjb所构成的分压电路，对此不再赘述。
S703：根据配置规则，为输出电路i配置与开关电路Ki对应的硬件地址。如前所述，为输出电路i分配的硬件地址需要与开关电路Ki满足对应关系，该对应关系便为配置规则。在一种可能的实现方式中，该配置规则可以表述为输出电路i的硬件地址为第一开关电路Ki的标识信息。示例性的，开关电路Ki的标识信息可以是开关电路Ki的序号，例如开关电路K1至KN在电子设备中的序号分别为1至N，则开关电路K1至KN分别对应的硬件地址为1至N，即输出电路1至N的硬件地址分别为1至N。开关电路Ki的序号为i，对应的输出电路i的硬件地址为i。
可以理解开关电路K1至KN在电子设备中的序号也可以为其它类型，如K1至KN的序号分别为N至1，输出电路1至N的硬件地址分别为N至1。此外，也可以用二进制的形式表示开关电路的序号和输出电路的硬件地址，本申请实施例对此并不多作限定。
S704：向输出电路i发送配置信息，该配置信息用于指示为输出电路i分配的硬件地 址。具体实现可以参考S304，对此不再赘述。
至此，便完成了为输出电路i配置硬件地址。
针对如图6所示的电子设备，本申请实施例四还提供一种配置硬件地址的方法，可以依次为图6中输出电路1至N配置硬件地址。示例性的，可以如图9所示，主要包括以下步骤：
S901：控制电路101启动识别。S901的具体实现可以参考实施例二所述的步骤S501，其它不再赘述。
S902：控制电路101开启第k个生产序列号对应的输出电路。S902的具体实现可以参考上述S502，其它不再赘述。
S903：控制电路101依次开启开关电路。示例性的，图9中按照开关电路的序号由1至N的顺序依次开启开关电路，即开关电路的序号m＝1。
可以理解，也可以按照由序号2至N+1，由N至1，等等多种可能的顺序依次开启各个开关电路。
S904：控制电路101检测检测导线的总输出信号。
S905：控制电路101判断总输出信号的电压值是否大于电压门限。若是，则继续执行S907，若否，则继续执行S906。
S906：控制电路101开启下一个开关电路，也可以理解为开启序号为m+1的电路，在接下来的步骤中，m取值加1，即m＝m+1。并继续执行S904。可以理解，连续两次执行S904之间可以间隔一定的时延，本申请实施例对此并不多作限制。
S907：控制电路101在检测到检测导线的总输出信号的电压值大于电压门限后，便可以关闭第k个生产序列号对应的输出电路。确定第k个生产序列号对应的输出电路所耦合的开关电路，从而可以为第k个生产序列号分配硬件地址，该步骤的具体实现可以参考上述实施例三，对此不再赘述。
如图6和图8所示，检测导线和控制电路101之间还可以设置有放电电路105，放电电路的具体实现可以参考上述实施例二，对此不再赘述。
有鉴于此，如图9，本方法还包括S908：控制电路101开启放电电路105，并检测检测导线的总输出信号。
S909：控制电路101判断检测导线的总输出信号的电压值是否低于预设阈值，若是，则继续执行S910，若否，则返回S908。
S910至S912的具体实现可以参考上述S508至S510，对此不再赘述。在执行完S912后，返回并继续执行S903。
通过上述实施例一至实施例四可见，本申请实施例所提供的电子设备及硬件地址配置方法，其中，电子设备内部的控制电路可以自行为各个输出电路配置硬件地址，省去了人工手动配置硬件地址的过程，不仅可以减少维护成本，而且还可以减少人工干预，从而降低错误发生，提高电子设备的可靠性。而且，采用本申请实施例所提供的技术方案，无需在输出电路的前面板上设置拨号开关，有利于降低输出电路的成本，因此有利于降低电子设备的成本。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和 范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
