Description

一种网络设备及设备管理方法 背景技术
网络设备是连接到网络中的物理实体，网络设备的种类繁多，例如服务器、集线器、PC(Personal Computer，个人计算机)、交换机、网桥、路由器、网关、NIC(Network Interface Card，网络接口卡)、AP(Access Point，接入点)等。对于企业来说，网络设备是重要资产之一，需要对网络设备进行维护和管理。
但是，网络设备由于某种原因断电后，可能无法定位到该网络设备，导致该网络设备处于失联状态。也就是说，由于无法获知哪个位置的网络设备已经断电，也就无法及时对该网络设备进行修复，从而导致该网络设备长时间处于断电状态。

具体实施方式
在本申请实施例使用的术语仅仅是出于描述特定实施例的目的，而非限制本申请。本申请和权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其它含义。还应当理解，本文中使用的术语“和/或”是指包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本申请实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，此外，所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
本申请实施例提出一种网络设备，可以包括主功能电路、串口标签电路和主电源。当然，还可以包括其它功能电路，对此不做限制，后续以主功能电路、串口标签电路和主电源为例进行说明。参见图1，为网络设备100的硬件结构图。
主功能电路110可以包括但不限于第一处理单元111和其它器件，对此不做限制。第一处理单元111可以是CPU(Central Processing Unit，中央处理器)，还可以是其他具备信息处理功能的硬件/软件模块，后续以CPU为例进行说明，可以将其称为第一CPU。其中，主功能电路110是传统网络设备具有的功能电路，例如，交换机的网络交换处理电路，路由器的路由功能实现电路等等，对此不再详加赘述。
串口标签电路120可以包括但不限于第二处理单元121、收发电路122、电源切换电路123、备用电源124(如备用电池等)和其它器件，对此不做限制。第二处理单元121可以是CPU，还可以是其他具备信息处理功能的硬件/软件模块，后续以CPU为例进行说明，可以将其称为第二CPU。其中，第二CPU与收发电路122电连接，第二CPU与电源切换电路123电连接，且电源切换电路123与主电源130和备用电源124均电连接。
串口标签电路120是一种与主功能电路110相对独立的电路。在网络设备100的主电源130供电时，串口标签电路120能够充当网络设备100的无线串口，与调试设备交互调试信息。在网络设备100的主电源130未供电时，串口标签电路120能够周期性地发送信标帧，使得定位设备能够根据信标帧定位该网络设备100，避免该网络设备100处于失联状态。
参见图1，网络设备100还包括主电源130，串口标签电路还包括备用电源124，主电源130与主功能电路110连接，主电源130与串口标签电路120的电源切换电路123连接，备用电源124与串口标签电路120的电源切换电路123连接。在主电源130供电时，由主电源130为主功能电路110和串口标签电路120供电，主功能电路110处于工作状态，且串口标签电路120处于工作状态。在主电源130未供电时，由备用电源124为串口标签电路120供电，备用电源124不为主功能电路110供电，这样，主功能电路 110未处于工作状态，且串口标签电路120处于工作状态。
其中，主功能电路110与主电源130连接。在主电源130供电时，则可以由主电源130为主功能电路110供电，从而使得主功能电路110处于工作状态。在主电源130未供电时，主电源130无法为主功能电路110供电，从而使得主功能电路110未处于工作状态。
其中，参见图2，为电源切换电路123与第二处理单元121、主电源130、备用电源124的连接示意图，电源切换电路123与主电源130和备用电源124分别连接，并与串口标签电路120的第二处理单元121连接。基于图2所示实施例，在主电源130供电时，则电源切换电路123可以选择主电源130为串口标签电路120供电；在主电源130未供电时，则电源切换电路123可以选择备用电源124为串口标签电路120供电。
在一个例子中，串口标签电路120的第二处理单元121检测到主功能电路110由工作状态切换到非工作状态时，向所述电源切换电路123发送电源切换信号；电源切换电路123在接收到所述电源切换信号时，选择备用电源124为串口标签电路120供电。具体的，串口标签电路120的第二处理单元121检测GPIO(General Purpose Input Output，通用输入输出)端口从高电平状态切换到低电平状态时，可以确定主功能电路110由工作状态切换到非工作状态，该过程在后续实施例中介绍。所述电源切换信号可以为第二处理单元121的一个输出管脚输出的高电平信号或低电平信号，通过该管脚输出的高低电平信号指示电源切换电路123选择使用哪个电源。所述电源切换电路123可以包括开关，根据电源切换信号的指示，决定选择由哪个电源连通至串口标签电路120。在一个示例中，第二处理单元121输出高电平信号时，电源切换电路123闭合连接主电源130与第二处理单元121的第一开关并打开连接备用源124与第二处理单元121的第二开关。在另一个示例中，第二处理单元121输出低电平信号时，电源切换电路123闭合第二开关并打开第一开关。
本申请实施例中，串口标签电路120可以发送携带工作状态信息的第一信标帧，以使接收到第一信标帧的调试设备能够根据第一信标帧向网络设备100发送连接请求，或，串口标签电路120发送携带非工作状态信息的第二信标帧，以使接收到第二信标帧的定位设备能够根据非工作状态信息对网络设备100进行定位。以下对此方案进行说明。
情况一、当检测到主功能电路110处于工作状态时，串口标签电路120发送携带工作状态信息的第一信标帧，所述第一信标帧指示接收到第一信标帧的调试设备能够向网络设备100发送连接请求。进一步的，若接收到调试设备发送的连接请求，则串口标签 电路120根据该连接请求与该调试设备建立无线连接，并通过该无线连接与该调试设备传输调试信息。具体的，当检测到主功能电路110处于工作状态时，串口标签电路120发送携带工作状态信息的第一信标帧，第一信标帧指示接收到第一信标帧的调试设备能够根据该工作状态信息向网络设备100发送连接请求。当调试设备依据第一信标帧的工作状态信息确定主功能电路110处于工作状态时，则会向网络设备100发送连接请求。
在一个例子中，串口标签电路120通过GPIO端口与主功能电路110连接。例如，当检测到GPIO端口处于高电平状态时，则串口标签电路120可以确定主功能电路110处于工作状态；当检测到GPIO端口处于低电平状态时，则串口标签电路120可以确定主功能电路110未处于工作状态。
其中，GPIO端口的初始状态为低电平状态，在主功能电路110处于工作状态时，则主功能电路110可以将GPIO端口的电平状态设置为高电平状态。在主功能电路110未处于工作状态(即处于非工作状态)时，则主功能电路110无法将GPIO端口的电平状态设置为高电平状态，即GPIO端口处于低电平状态。也就是说，当GPIO端口处于高电平状态时，表示主功能电路110处于工作状态；当GPIO端口处于低电平状态时，表示主功能电路110未处于工作状态(即处于非工作状态)。
参见图1，串口标签电路120的CPU(即第二CPU)通过GPIO端口与主功能电路110的CPU(即第一CPU)连接。在初始状态下，该GPIO端口可以处于低电平状态，使GPIO端口处于低电平状态的方式很多，例如由于外部下拉电阻而使GPIO端口处于低电平状态，或者例如主功能电路110的第一CPU将该GPIO端口的电平状态设置为低电平状态，本实施例对如何使GIOP端口处于低电平状态不做限制，只要能够使GPIO端口处于低电平状态即可。在主功能电路110处于工作状态时，则主功能电路110的第一CPU可以将GPIO端口的电平状态从低电平状态设置为高电平状态，例如，主功能电路110的第一CPU可以输出高电平信号，使得GPIO端口的电平状态从低电平状态变为高电平状态，对此不做限制，只要能够将GPIO端口的电平状态设置为高电平状态即可。基于此，串口标签电路120的第二CPU在感知到该GPIO端口处于高电平状态时，则可以确定主功能电路110处于工作状态。
此外，在主功能电路110未处于工作状态时，例如，主功能电路110处于掉电状态，则主功能电路110的第一CPU无法将GPIO端口的电平状态从低电平状态设置为高电平状态，也就是说，GPIO端口将保持低电平状态。基于此，串口标签电路120的第二CPU在感知到该GPIO端口处于低电平状态时，则可以确定主功能电路110未处于工作 状态(即处于非工作状态)。
综上所述，在主电源130供电时，主功能电路110处于工作状态，则主功能电路110可以将GPIO端口的电平状态设置为高电平状态，因此，串口标签电路120的第二CPU检测到GPIO端口处于高电平状态时，可以确定主功能电路110为工作状态，此时不会向电源切换电路123发送电源切换信号。电源切换电路123未接收到电源切换信号，获知当前由主电源130供电，继续选择主电源130为串口标签电路120供电。
在主电源130未供电时，则主功能电路110处于非工作状态，因此主功能电路110无法将GPIO端口的电平状态从低电平状态设置为高电平状态。串口标签电路120的第二CPU检测到GPIO端口处于低电平状态，确定主功能电路110为非工作状态，并向电源切换电路123发送电源切换信号。电源切换电路123接收到电源切换信号，获知当前主电源130未供电，选择备用电源124为串口标签电路120供电。
在一个例子中，串口标签电路120确定主功能电路110处于工作状态时，可以发送第一信标帧，该第一信标帧可以携带工作状态信息，所述工作状态信息表示主功能电路110处于工作状态。调试设备能够通过串口标签电路120与主功能电路110交互调试信息。基于此，调试设备在接收到第一信标帧后，若发现第一信标帧中存在工作状态信息，则确定网络设备100的主功能电路110处于工作状态，向网络设备100的串口标签电路120发送连接请求，以与网络设备100建立连接。
串口标签电路120可以周期性发送携带工作状态信息的第一信标帧，直到接收到调试设备发送的连接请求，则停止发送第一信标帧。
串口标签电路120的第二CPU确定主功能电路110处于工作状态时，生成携带工作状态信息的第一信标帧，将第一信标帧传输给收发电路122。收发电路122接收到第一信标帧后，从收发电路122的天线口发送第一信标帧。调试设备接收到第一信标帧后，若发现第一信标帧包括工作状态信息，确定网络设备100的主功能电路110处于工作状态，可以向网络设备100发送连接请求。网络设备100的串口标签电路120的收发电路122接收连接请求，将连接请求传输给串口标签电路120的第二CPU。串口标签电路120的第二CPU得到连接请求后，根据该连接请求与调试设备建立无线连接，并通过该无线连接与该调试设备相互传输调试信息。
在一个例子中，收发电路122可以包括射频模块和天线。射频模块可以包括特定频段的放大器、滤波器，以及相应的时钟芯片等。可以使用支持串口标签电路120所应用 的无线协议的芯片来实现该射频模块的功能。在另一例子中，支持无线协议的芯片还可以实现第二处理单元121的功能。图1只是示例性的按功能划分了各个模块或电路，在具体实现上，可以使用同一器件实现不同的模块或电路的功能。
在一个例子中，串口标签电路120可以通过串口与主功能电路110连接。基于此，串口标签电路120通过无线连接与调试设备相互传输调试信息时具体用于：串口标签电路120通过串口接收主功能电路110发送的第一串口调试信息，将第一串口调试信息转换为符合该无线连接应用的无线协议的第一无线调试信息，并通过该无线连接将第一无线调试信息发送给调试设备；和/或，串口标签电路120通过无线连接接收调试设备发送的第二无线调试信息，并将该第二无线调试信息转换为符合该串口应用的串口协议的第二串口调试信息，并通过串口将该第二串口调试信息发送给主功能电路110。
后续以与调试设备建立无线连接应用的协议是蓝牙协议为例进行说明，当然，与调试设备建立无线连接应用的协议还可以为其它类型的无线连接协议，例如，与调试设备建立无线连接应用的协议可以为Wi-Fi(Wireless Fidelity，无线保真)协议、ZigBee(紫蜂协议)协议，对协议的类型不做限制。
其中，串口标签电路120的第二CPU与调试设备建立基于蓝牙协议的无线连接后，该第二CPU可以通过串口接收主功能电路110发送的串口调试信息，将串口调试信息添加到蓝牙协议规定的数据帧的载荷字段中，从而将串口调试信息封装到蓝牙协议规定的数据帧中，即将串口调试信息转换为无线调试信息，无线调试信息即为封装串口调试信息的数据帧。然后，串口标签电路120的第二CPU可以将无线调试信息传输给收发电路122，收发电路122在得到无线调试信息后，可以通过无线连接发送该无线调试信息，即该无线调试信息被发送给调试设备。这样，调试设备就可以接收到该无线调试信息。此为网络设备100向调试设备发送无线调试信息的过程，下面介绍网络设备100接收调试设备发送的无线调试信息的过程。
串口标签电路120的第二CPU与调试设备建立基于蓝牙协议的无线连接后，串口标签电路120的收发电路122通过无线连接接收调试设备发送的无线调试信息，将无线调试信息发送给串口标签电路120的第二CPU。串口标签电路120的第二CPU得到无线调试信息后，解析该无线调试信息，获取串口调试信息，即数据帧的载荷字段中获取到串口调试信息，此为将无线调试信息转换为串口调试信息的过程。然后再通过串口将串口调试信息发送给主功能电路110的第一CPU。这样，主功能电路110的第一CPU可以接收到串口调试信息。
在上述实施例中，本方案不限定串口调试信息在载荷字段的具体位置，只要能够将串口调试信息承载在无线连接协议的载荷字段中即可。
在另一个实施例中，还可以利用SPP(Serial Port Profile，串口配置文件)协议(为蓝牙协议中的一种)实现串口调试信息与无线调试信息之间的转换。其中，串口标签电路120的第二CPU与调试设备建立蓝牙无线连接后，该第二CPU可以通过串口接收主功能电路110发送的串口调试信息，并利用SPP将串口调试信息转换为无线调试信息。然后，串口标签电路120的第二CPU可以将无线调试信息传输给收发电路122，收发电路122在得到无线调试信息后，可以通过蓝牙无线连接发送该无线调试信息，即该无线调试信息被发送给调试设备。这样，调试设备就可以接收到该无线调试信息。此为网络设备100向调试设备发送无线调试信息的过程，下面介绍网络设备100接收调试设备发送的无线调试信息的过程。
串口标签电路120的第二CPU与调试设备建立蓝牙无线连接后，串口标签电路120的收发电路122通过蓝牙无线连接接收调试设备发送的无线调试信息，将无线调试信息发送给串口标签电路120的第二CPU。串口标签电路120的第二CPU得到无线调试信息后，利用SPP协议将无线调试信息转换为串口调试信息，并通过串口将串口调试信息发送给主功能电路110的第一CPU。这样，主功能电路110的第一CPU可以接收到串口调试信息。
在上述实施例中，SPP协议定义了无线调试信息与串口调试信息之间的转换规则，如可以采用SPP协议将无线调试信息转换为串口调试信息，也可以采用SPP协议将串口调试信息转换为无线调试信息。本方案不限定定义转换规则的协议，只要能够实现无线调试信息与串口调试信息的互相转换即可。
在上述实施例中，网络设备100向调试设备发送的调试信息，可以包括但不限于：网络设备100的打印配置、CPU运行百分比、内存大小、CPU型号等，对此调试信息不做限制。调试设备向网络设备100发送的调试信息，可以包括但不限于：用于请求打印配置的信息、用于请求CPU运行百分比的信息、用于请求内存大小的信息、用于请求CPU型号的信息等，对此调试信息不做限制。
情况二、当检测到主功能电路110未处于工作状态时，则串口标签电路120发送携带非工作状态信息的第二信标帧，第二信标帧指示接收到第二信标帧的定位设备能够根据非工作状态信息对网络设备100进行定位，即确定网络设备100的位置。
在一个例子中，串口标签电路120确定主功能电路110处于非工作状态时，可以发送第二信标帧，该第二信标帧可以携带非工作状态信息，所述非工作状态信息用于表示主功能电路110处于非工作状态。基于此，其他设备可以对网络设备100进行定位。例如，定位设备在接收到第二信标帧后，若发现第二信标帧中存在非工作状态信息，则确定网络设备100的主功能电路110处于非工作状态，并可以对网络设备100进行定位。
在一个例子中，串口标签电路120发送携带非工作状态信息的第二信标帧时具体用于：周期性发送第二信标帧，并拒绝接受针对第二信标帧的连接请求，也就是说，即使接收到连接请求，也不会根据该连接请求建立无线连接。
参见图1，串口标签电路120的第二CPU确定主功能电路110处于非工作状态时，则生成携带非工作状态信息的第二信标帧，并将第二信标帧发送给收发电路122。收发电路122在得到第二信标帧后，可以在收发电路122的天线口发送该第二信标帧。定位设备在接收到该第二信标帧后，若发现该第二信标帧中存在非工作状态信息，则确定网络设备100的主功能电路110处于非工作状态，造成主功能电路110处于非工作状态的原因有很多，本方案不作限制，只要能够使主功能电路110处于非工作状态即可。例如，网络设备100的主功能电路110由于掉电而无法正常工作。此时，定位设备可以对该网络设备100进行定位。本方案对定位方式不做限制，以下仅作示例。
例如，第二信标帧可以被广播发送给多个定位设备，如三个定位设备，通过这三个定位设备分别接收到第二信标帧的信号强度，以及这三个定位设备各自的位置，就可以定位出网络设备100的位置(如经纬度坐标)，可以采用预设算法，如基于接收信号强度的定位算法，定位出网络设备的位置，对此定位算法不做限制。
在上述实施例中，第一信标帧和第二信标帧均可以为符合蓝牙协议的beacon帧。
传统的信标帧不携带工作状态信息或者非工作状态信息，因此，本申请中，可以对传统的信标帧进行改进，如复用信标帧的已有字段(如保留字段)或者添加新字段，通过该字段携带工作状态信息或者非工作状态信息。例如，通过该字段携带工作标记，当工作标记为第一标识时，表示信标帧携带工作状态信息，此时的信标帧为第一信标帧；当工作标记为第二标识时，表示信标帧携带非工作状态信息，此时的信标帧为第二信标帧。当然，上述方式只是示例，只要信标帧携带工作状态信息或者非工作状态信息即可。此处改进能够使接收信标帧的设备确定网络设备100的主功能电路110是否处于工作状态。
以符合蓝牙协议的信标帧为例，如图3所示，蓝牙信标帧可以包括头(Header)和载荷(Payload)字段。如图4所示，在头字段中包括4bit的保留字段(RFU)。在一个例子中，RFU的一个bit可以用来携带工作标记。例如，当该bit设置为0时，可以表示信标帧携带工作状态信息；当该bit设置为1时，可以表示信标帧携带非工作状态信息。在另一个例子中，也可以使用载荷字段来携带工作标记，例如可以在载荷字段自定义一个表示工作标记的新字段。
在一个例子中，信标帧中还可以携带连接信息，该连接信息可以为可连接或者不可连接。基于此，串口标签电路120在发送上述第一信标帧或者第二信标帧之前，还可以在第一信标帧或者第二信标帧中添加连接信息，且该连接信息可以为可连接或者不可连接。仍以蓝牙信标帧为例，在该信标帧的头字段中包括连接信息，即在头字段的PDU Type字段指示了连接信息，具体的，PDU(Protocol Data Unit)类型的值表明了发送该信标帧的设备是否可以连接。例如，当PDU类型为ADV_IND或ADV_DIRECT_IND的时候，发送该信标帧的设备是可以连接的；当PDU类型为ADV_NONCONN_IND或ADV_SCAN_IND的时候，发送该信标帧的设备是不可以连接的。更多的可连接或不可连接的PDU类型可以参考具体的蓝牙协议。
若第一信标帧中携带的连接信息是可连接，则调试设备可以向网络设备100发送连接请求，且网络设备100的串口标签电路120接收到该连接请求后，可以与调试设备建立无线连接。若第一信标帧中携带的连接信息是不可连接，则调试设备可以不向网络设备100发送连接请求，即使调试设备向网络设备100发送连接请求，网络设备100的串口标签电路120接收到该连接请求后，也不会与调试设备建立无线连接。在一个示例中，调试设备接收到的信标帧中携带工作状态信息，调试设备确定网络设备100的主功能电路110处于工作状态信息，此时调试设备获取该信标帧携带的连接信息。若携带的连接信息为可连接，则向网络设备100发送连接请求。或者，调试设备获取到的该信标帧携带的连接信息为不可连接，调试设备向网络设备100发送连接请求，但网络设备100的串口标签电路120接收到该连接请求后，并不会与调试设备建立无线连接。
无论第二信标帧中携带的连接信息是可连接还是不可连接，调试设备或定位设备可以不向网络设备100发送连接请求，即使调试设备或定位设备向网络设备100发送连接请求，网络设备100的串口标签电路120接收到该连接请求后，也不会与调试设备或定位设备建立无线连接。在一个示例中，调试设备或定位设备接收到的信标帧中携带非工作状态信息，调试设备或定位设备确定网络设备100的主功能电路110处于非工作状态 信息，此时调试设备或定位设备可以不关注该信标帧携带的连接信息，不向网络设备100发送连接请求。或者，调试设备或定位设备获取到的该信标帧携带的连接信息为可连接，调试设备或定位设备向网络设备100发送连接请求，但网络设备100的串口标签电路120接收到该连接请求后，并不会与调试设备或定位设备建立无线连接。
在一个例子中，上述调试设备可以是用于对网络设备100进行调试的设备，如PC、移动终端等，对此调试设备的类型不做限制。在安装网络设备100或网络设备100故障时，工作人员可以使用调试设备对网络设备100进行调试。在传统方式中，工作人员是通过线缆连接调试设备与网络设备100的。本申请中，不需要使用线缆连接调试设备与网络设备100，可以在调试设备与网络设备100之间建立无线连接，并使用无线连接相互传输调试信息，实现对网络设备100的调试，对具体的调试过程不做限制。
在一个例子中，上述定位设备可以是用于对网络设备100进行定位的设备，如AP等，对此定位设备的类型不做限制。在网络设备100掉电时，基于网络设备100的串口标签电路120发送的第二信标帧，则可以使用定位设备对掉电的网络设备100进行定位，从而可以获知哪个位置的网络设备100已经断电。
基于上述技术方案，本申请实施例中，可以在网络设备100部署串口标签电路120，串口标签电路120可以判断网络设备100的主功能电路110是否处于工作状态。如果主功能电路110处于工作状态，则串口标签电路120发送携带工作状态信息的第一信标帧，以使接收到所述第一信标帧的调试设备能够根据第一信标帧向网络设备100发送连接请求。若串口标签电路120接收到调试设备发送的连接请求，则根据连接请求与调试设备建立无线连接，并通过无线连接与调试设备相互传输调试信息。如果主功能电路110不处于工作状态，则串口标签电路120发送携带非工作状态信息的第二信标帧，以使接收到所述第二信标帧的定位设备能够根据非工作状态信息对网络设备100进行定位。网络设备100由于某种原因断电后，主功能电路110未处于工作状态，则串口标签电路120可以发送第二信标帧，定位设备可以根据第二信标帧对网络设备100进行定位，从而避免网络设备100处于失联状态。同时，可以获知哪个位置的网络设备100已经断电，并对网络设备100进行修复，避免网络设备100长时间处于断电状态。另一方面，在主功能电路110处于工作状态时，则串口标签电路120可以发送第一信标帧，使得调试设备根据第一信标帧与网络设备100建立无线连接，这样，调试设备与网络设备100可以通过无线连接相互传输调试信息，而不用采用有线方式相互传输调试信息，也就是说，不需要使用线缆连接调试设备与网络设备100，就可以对网络设备100进行调试，方便 灵活，节省了硬件成本。
基于与上述方案同样的申请构思，本申请实施例还提出一种设备管理方法，参见图5，为该设备管理方法的流程示意图，该方法可以应用于网络设备的串口标签电路，且网络设备还可以包括主功能电路，该方法包括。
步骤301，当检测到主功能电路处于工作状态时，则发送携带工作状态信息的第一信标帧，其中，该第一信标帧指示接收到该第一信标帧的调试设备能够根据该第一信标帧向网络设备发送连接请求。例如，调试设备在接收到第一信标帧后，若发现第一信标帧中存在工作状态信息，则确定网络设备的主功能电路处于工作状态，并向网络设备的串口标签电路发送连接请求。
步骤302，若接收到调试设备发送的连接请求，则根据该连接请求与调试设备建立无线连接，并通过该无线连接与调试设备相互传输调试信息。
步骤303，当检测到主功能电路未处于工作状态时，则发送携带非工作状态信息的第二信标帧，其中，该第二信标帧指示接收到该第二信标帧的定位设备能够根据该非工作状态信息对网络设备进行定位，即确定网络设备的位置。
在一个例子中，串口标签电路确定主功能电路处于非工作状态时，可以发送第二信标帧，该第二信标帧可以携带非工作状态信息，所述非工作状态信息用于表示主功能电路处于非工作状态。基于此，可以通过其他设备对网络设备进行定位。例如，定位设备在接收到第二信标帧后，若发现第二信标帧中存在非工作状态信息，则确定网络设备的主功能电路处于非工作状态，并可以对网络设备进行定位。
其中，步骤301和步骤303并没有先后顺序，当主功能电路处于工作状态时，执行步骤301和步骤302，当主功能电路未处于工作状态时，执行步骤303。
在一个例子中，串口标签电路可以通过GPIO端口与主功能电路连接；当检测到GPIO端口处于高电平状态时，则确定主功能电路处于工作状态；当检测到GPIO端口处于低电平状态时，则确定主功能电路未处于工作状态。
其中，GPIO端口的初始状态为低电平状态，如由于外部下拉电阻而处于低电平状态。在主功能电路处于工作状态时，则主功能电路将GPIO端口的电平状态设置为高电平状态，如主功能电路输出高电平信号，使GPIO端口的电平状态从低电平状态变为高电平状态。在主功能电路未处于工作状态(即处于非工作状态)时，主功能电路无法将GPIO端口的电平状态设置为高电平状态，即GPIO端口处于低电平状态。基于此，当 GPIO端口处于高电平状态时，表示主功能电路处于工作状态；当GPIO端口处于低电平状态时，表示主功能电路未处于工作状态(即处于非工作状态)。
在一个例子中，发送携带工作状态信息的第一信标帧，包括：周期性发送第一信标帧，直到接收到调试设备发送的连接请求，则停止发送第一信标帧。
在一个例子中，发送携带非工作状态信息的第二信标帧，可以包括：周期性发送第二信标帧，并且拒绝接受针对该第二信标帧的连接请求。
在一个例子中，串口标签电路还可以通过串口与主功能电路连接；基于此，通过无线连接与调试设备相互传输调试信息，可以包括但不限于：
通过该串口接收主功能电路发送的第一串口调试信息，将该第一串口调试信息转换为符合无线连接应用的无线协议的第一无线调试信息，并通过无线连接将该第一无线调试信息发送给调试设备；和/或，通过无线连接接收调试设备发送的第二无线调试信息，将该第二无线调试信息转换为符合该串口应用的串口协议的第二串口调试信息，并通过串口将该第二串口调试信息发送给主功能电路。
例如，与所述调试设备建立无线连接所应用的协议是蓝牙协议，串口标签电路与调试设备建立无线连接后，可以通过串口接收主功能电路发送的串口调试信息，将串口调试信息添加到蓝牙协议规定的数据帧的载荷字段中，从而将串口调试信息封装到蓝牙协议规定的数据帧中，即将串口调试信息转换为无线调试信息，无线调试信息即为封装串口调试信息的数据帧。然后，串口标签电路通过无线连接发送该无线调试信息，即该无线调试信息被发送给调试设备，这样，调试设备可以接收到该无线调试信息。串口标签电路与调试设备建立基于蓝牙协议的无线连接后，串口标签电路可以通过无线连接接收调试设备发送的无线调试信息，解析该无线调试信息，获取串口调试信息，即从数据帧的载荷字段中获取到串口调试信息，此为将无线调试信息转换为串口调试信息的过程。然后通过串口将串口调试信息发送给主功能电路，主功能电路可以接收到串口调试信息。此外，本申请提供的方法与调试设备建立无线连接时应用的协议还可以是Wi-Fi协议、ZigBee协议，对无线连接的协议类型不做限制，应当理解的是，将串口调试信息添加到这些协议的载荷字段中，即可实现串口调试信息到无线调试信息的转换。相应的，解析无线调试信息，获取载荷字段中的串口调试信息，即可实现无线调试信息到串口调试信息的转换。
又例如，与所述调试设备建立无线连接所应用的协议是蓝牙协议，串口标签电路与 调试设备建立无线连接后，可以通过串口接收主功能电路发送的串口调试信息，并利用SPP协议将串口调试信息转换为无线调试信息。然后，串口标签电路通过无线连接发送该无线调试信息，即该无线调试信息被发送给调试设备，这样，调试设备可以接收到该无线调试信息。串口标签电路与调试设备建立无线连接后，串口标签电路可以通过无线连接接收调试设备发送的无线调试信息，利用SPP协议将无线调试信息转换为串口调试信息，并通过串口将串口调试信息发送给主功能电路，主功能电路可以接收到串口调试信息。
在一个例子中，网络设备还包括主电源，串口标签电路还包括备用电源。当检测到主功能电路由工作状态切换到非工作状态时，则可以选择备用电源为串口标签电路供电。具体的，当检测串口标签电路的GPIO端口从高电平状态切换到低电平状态时，可以认为主功能电路由工作状态切换到非工作状态。
其中，在主电源供电时，主功能电路处于工作状态，则主功能电路可以将GPIO端口的电平状态设置为高电平状态，因此，串口标签电路检测到GPIO端口为高电平状态时，可以确定主功能电路为工作状态，能够获知当前由主电源供电，继续选择主电源为串口标签电路供电。
在主电源未供电时，则主功能电路处于非工作状态，因此主功能电路无法将GPIO端口的电平状态从低电平状态设置为高电平状态。串口标签电路检测到GPIO端口处于低电平状态，确定主功能电路为非工作状态，可以能够获知当前主电源未供电，选择备用电源为串口标签电路供电。
在一个例子中，上述第一信标帧可以包括工作标记，当该工作标记为第一标识时，表示第一信标帧携带工作状态信息；上述第二信标帧可以包括工作标记，当该工作标记为第二标识时，表示第二信标帧携带非工作状态信息。
上述实施例阐明的第一处理单元111和第二处理单元121，还可以由一个或多个应用专用集成电路(ASIC)、数字信号处理器(DSP)、可编程逻辑器件(PLD)、现场可编程门阵列(FPGA)、控制器、微控制器、微处理器或其他电子元件实现，本申请对此不做限制。
