背景技术Background technique

在安防监控技术领域，通常会通过监控***获取监控图像并显示监控图像。监控***主要包括网络硬盘录像机(Network Video Recorder，NVR)和至少一个网络摄像机(Internet Protocol Camera，IPC)。其中，NVR设置有无线保真(WIreless-Fidelity，WIFI)接入点(Access Point，AP)，IPC具有WIFI连接功能。IPC通过连接WIFI AP与NVR关联。其中，IPC用于将获取的监控图像传输至NVR，NVR用于显示该监控图像。该过程中，用户需要执行较多操作，过程很繁琐。In the field of security monitoring technology, monitoring images are usually obtained through a monitoring system and display of monitoring images. The monitoring system mainly includes a Network Video Recorder (NVR) and at least one Internet Protocol Camera (IPC). Among them, the NVR is provided with a WIreless-Fidelity (WIFI) access point (AP), and the IPC has a WIFI connection function. The IPC is associated with the NVR by connecting to the WIFI AP. The IPC is used to transmit the acquired monitoring image to the NVR, and the NVR is used to display the monitoring image. In this process, the user needs to perform more operations, and the process is cumbersome.

相关技术中有一种设备接入方法，该方法中，手机在接收到用户触发的操作指令后，向IPC发送编码后的报文，该编码后的报文包括预设的WIFI AP的服务集标识(Service Set Identifier，SSID)和IPC接入WIFI网络的接入密钥。IPC采用对应的解码规则对该编码后的报文进行解码，得到SSID和接入密钥。IPC将解码后得到的SSID和接入密钥发送至NVR。当NVR确定IPC发送的SSID与预设的SSID相同时，NVR允许对该IPC进行接入认证操作，该过程为预认证过程。之后，NVR基于IPC发送的接入密钥对该IPC进行接入认证操作。如果认证成功，则IPC与NVR关联成功。The related art has a device access method, in which the mobile phone sends a coded message to the IPC after receiving the operation command triggered by the user, and the coded message includes a preset service set identifier of the WIFI AP. (Service Set Identifier, SSID) and the access key of the IPC accessing the WIFI network. The IPC decodes the encoded message by using a corresponding decoding rule to obtain an SSID and an access key. The IPC sends the decoded SSID and access key to the NVR. When the NVR determines that the SSID sent by the IPC is the same as the preset SSID, the NVR allows the access authentication operation to be performed on the IPC, and the process is a pre-authentication process. Afterwards, the NVR performs an access authentication operation on the IPC based on the access key sent by the IPC. If the authentication is successful, the IPC is successfully associated with the NVR.

上述过程需要在手机接收到用户触发的操作指令后完成预认证过程，无法实现设备自动预认证，预认证过程仍较繁琐。The above process needs to complete the pre-authentication process after the mobile phone receives the operation instruction triggered by the user, and the device cannot be automatically pre-authenticated. The pre-authentication process is still cumbersome.

综上所述，本申请实施例提供的设备接入方法，IPC能够获取NVR广播的通知消息，并在通知消息包括预设的WIFI AP的标识时，周期性广播接入请求消息，该接入请求消息包括IPC的标识，以便于NVR在检测到预设标识集中存在接入请求消息中的IPC的标识时，NVR允许对IPC进行接入认证操作，整个过程无需手机接收用户触发的操作指令，实现了设备自动预认证，简化了预认证过程。In summary, in the device access method provided by the embodiment of the present application, the IPC can obtain the notification message of the NVR broadcast, and periodically broadcast the access request message when the notification message includes the identifier of the preset WIFI AP, and the access is performed. The request message includes the identifier of the IPC, so that the NVR allows the access authentication operation to be performed on the IPC when the NVR detects the identifier of the IPC in the access request message. The entire process does not require the mobile phone to receive the operation instruction triggered by the user. The device automatically pre-certifies and simplifies the pre-authentication process.

图4是根据一示例性实施例示出的一种设备接入方法的方法流程图，该设备接入方法可以用于图1所示的实施环境。参见图4，该方法流程可以包括如下几个步骤：FIG. 4 is a flowchart of a method for a device access method according to an exemplary embodiment, and the device access method may be used in the implementation environment shown in FIG. 1. Referring to FIG. 4, the method flow may include the following steps:

步骤401、NVR建立预设标识集。Step 401: The NVR establishes a preset identifier set.

该预设标识集包括NVR所管理的IPC的标识。比如NVR管理k个IPC，k≥2那么NVR建立的预设标识集包括k个IPC的标识。The preset identifier set includes an identifier of an IPC managed by the NVR. For example, the NVR manages k IPCs, and k≥2, then the preset identifier set established by the NVR includes the identifiers of k IPCs.

示例的，该NVR管理5个IPC，这个5个IPC分别是第一IPC、第二IPC、第三IPC、第四IPC和第五IPC，其中，第一IPC的标识为a1，第二IPC的标识为a2，第三IPC的标识为a3，第四IPC的标识为a4，第五IPC的标识为a5。那么该NVR建立的预设标识集可以如表1所示，表1中包括这5个IPC的标识。For example, the NVR manages five IPCs, and the five IPCs are a first IPC, a second IPC, a third IPC, a fourth IPC, and a fifth IPC, where the identifier of the first IPC is a1, and the second IPC is The identifier is a2, the identifier of the third IPC is a3, the identifier of the fourth IPC is a4, and the identifier of the fifth IPC is a5. Then, the preset identifier set established by the NVR can be as shown in Table 1, and the identifiers of the five IPCs are included in Table 1.

表1Table 1

示例的，IPC的标识可以为IPC的产品序列号。或者，也可以给每个IPC赋予一个编号，每个IPC的标识可以是对应IPC的编号。示例的，第一IPC至第五IPC的编号分别为001、002、003、004和005，那么第一IPC至第五IPC的标识可以分别为001、002、003、004和005。当然，IPC的标识还可以为其他表示形式，本申请实施例对IPC的标识的表示形式不做限定。For example, the ID of the IPC can be the product serial number of the IPC. Alternatively, each IPC may be assigned a number, and the identifier of each IPC may be the number corresponding to the IPC. For example, the numbers of the first IPC to the fifth IPC are 001, 002, 003, 004, and 005, respectively, and the identifiers of the first IPC to the fifth IPC may be 001, 002, 003, 004, and 005, respectively. Of course, the identifier of the IPC may also be in other forms. The embodiment of the present application does not limit the representation of the identifier of the IPC.

步骤402、NVR周期性广播通知消息。Step 402: The NVR periodically broadcasts the notification message.

可选的，NVR可以周期性广播信标(beacon)帧，该信标帧用于指示通知消息，即通过信标帧可以确定通知消息的具体内容。Optionally, the NVR may periodically broadcast a beacon frame, where the beacon frame is used to indicate a notification message, that is, the specific content of the notification message may be determined by the beacon frame.

作为一个无线网络标准，802.11的帧主要有三种类型：数据帧、控制帧和管理帧。其中，管理帧起到监督作用，用于加入或退出无线网络，以及处理WIFI AP之间关联的转移事宜。管理帧主要包括信标帧、探测请求(probe request)帧、探测响应(probe response)帧、认证请求(authentication request)帧、认证响应(authentication response)帧、关联请求(association request)帧和关联响应(association response)帧。As a wireless network standard, there are three main types of 802.11 frames: data frames, control frames, and management frames. The management frame plays a supervisory role for joining or exiting the wireless network, and processing the transfer of associations between the WIFI APs. The management frame mainly includes a beacon frame, a probe request frame, a probe response frame, an authentication request frame, an authentication response frame, an association request frame, and an association response. (association response) frame.

其中，信标帧用于声明WIFI网络的存在，定期发送信标帧可以使工作站(station)得知该WIFI网络的存在，从而使工作站在需要加入时能够调整加入WIFI网络所必需的参数。在本申请实施例中，IPC设置有工作站，IPC通过该工作站与NVR的WIFI AP进行通信。The beacon frame is used to declare the existence of the WIFI network, and periodically sending the beacon frame enables the workstation to know the existence of the WIFI network, so that the workstation can adjust the parameters necessary for joining the WIFI network when it needs to join. In the embodiment of the present application, the IPC is provided with a workstation through which the IPC communicates with the WIFI AP of the NVR.

工作站采用探测请求帧来扫描所在区域内的WIFI网络。当探测请求帧扫描的网络与工作站相兼容时，WIFI AP则会向该工作站发送探测响应帧。The workstation uses the probe request frame to scan the WIFI network in the area. When the network that probes the request frame scan is compatible with the workstation, the WIFI AP sends a probe response frame to the workstation.

当工作站接收到WIFI AP发送的探测响应帧时，工作站向WIFI AP发送认证请求帧。WIFI AP再向该工作站发送认证响应消息。之后，该工作站向WIFI AP 发送关联请求帧，WIFI AP再向该工作站发送关联响应帧。When the workstation receives the probe response frame sent by the WIFI AP, the workstation sends an authentication request frame to the WIFI AP. The WIFI AP then sends an authentication response message to the workstation. After that, the workstation sends an association request frame to the WIFI AP, and the WIFI AP sends an association response frame to the workstation.

需要说明的是，信标帧和探测请求帧的帧结构均包括多个元素(element)，每个元素的结构如表2所示，每个元素包括元素标识符、负载内容长度和负载内容。其中，元素标识符一共有255个，比如元素标识符的取值范围为1～255，通常，255个元素标识符中一部分会被定义使用，其余部分处于空闲状态。在本申请实施例中，为了实现设备自动预认证，实现设备自动关联，可以采用处于空闲状态的元素标识符将预设的WIFI AP的标识添加至信标帧中，将IPC的标识添加至探测请求帧中。添加时，需要参考信标帧和探测请求帧的帧结构，比如可以参考表2所示的元素的结构。本申请实施例对预设的WIFI AP的标识在信标帧中的位置不做限定，对IPC的标识在探测请求帧中的位置不做限定，也即是，表2中的元素标识符也可以位于负载内容长度与负载内容之间，或者，也可以位于负载内容之后。It should be noted that the frame structures of the beacon frame and the probe request frame each include a plurality of elements, and the structure of each element is as shown in Table 2. Each element includes an element identifier, a payload content length, and a payload content. There are 255 element identifiers. For example, the element identifier ranges from 1 to 255. Usually, some of the 255 element identifiers are defined and the rest are idle. In the embodiment of the present application, in order to implement automatic pre-authentication of the device and implement automatic association of the device, the identifier of the preset WIFI AP may be added to the beacon frame by using the element identifier in an idle state, and the identifier of the IPC is added to the probe. In the request frame. When adding, it is necessary to refer to the frame structure of the beacon frame and the probe request frame, for example, the structure of the elements shown in Table 2 can be referred to. In the embodiment of the present application, the location of the identifier of the preset WIFI AP in the beacon frame is not limited, and the location of the identifier of the IPC in the probe request frame is not limited, that is, the element identifier in Table 2 is also It can be between the payload content length and the payload content, or it can be located after the payload content.

示例的，预设的WIFI AP的标识的长度为1，内容为0x63(以0x开始的数据为16进制数据)，且信标帧的元素标识符1～255中的7～15未被定义使用，处于空闲状态，那么待添加的WIFI AP的标识所对应的元素的元素标识符可以为8，负载内容长度为1，负载内容为0x63。For example, the identifier of the preset WIFI AP has a length of 1, the content is 0x63 (the data starting with 0x is hexadecimal data), and 7 to 15 of the element identifiers 1 to 255 of the beacon frame are not defined. If the usage is in an idle state, the element corresponding to the identifier of the WIFI AP to be added may have an element identifier of 8, a payload content length of 1, and a load content of 0x63.

步骤403、IPC检测NVR广播的通知消息是否包括预设的WIFI AP的标识。Step 403: The IPC detects whether the notification message of the NVR broadcast includes the identifier of the preset WIFI AP.

IPC获取NVR广播的通知消息，检测NVR广播的通知消息是否包括预设的WIFI AP的标识。示例的，IPC可以从NVR周期性广播的信标帧中获取通知消息。The IPC obtains the notification message of the NVR broadcast, and detects whether the notification message of the NVR broadcast includes the identifier of the preset WIFI AP. For example, the IPC may obtain a notification message from a beacon frame periodically broadcast by the NVR.

步骤404、当通知消息包括预设的WIFI AP的标识时，IPC周期性广播接入请求消息，该接入请求消息包括IPC的标识。Step 404: When the notification message includes the identifier of the preset WIFI AP, the IPC periodically broadcasts an access request message, where the access request message includes an identifier of the IPC.

当NVR广播的通知消息包括预设的WIFI AP的标识时，IPC周期性广播接入请求消息。可选的，IPC可以周期性广播探测请求帧，该探测请求帧用于指示接入请求消息，即通过探测请求帧可以确定接入请求消息的具体内容。When the notification message broadcast by the NVR includes the identifier of the preset WIFI AP, the IPC periodically broadcasts the access request message. Optionally, the IPC may periodically broadcast a probe request frame, where the probe request frame is used to indicate an access request message, that is, the specific content of the access request message may be determined by the probe request frame.

在本申请实施例中，当IPC检测到获取的通知消息包括预设的WIFI AP的标识时，IPC再周期性广播接入请求消息，该接入请求消息包括IPC的标识。当IPC检测到获取的通知消息不包括预设的WIFI AP的标识时，IPC则不广播接入请求消息，在这种情况下，IPC拒绝与广播通知消息的设备关联，设备关联流程结束。这样一来，能够保证IPC的工作站仅与预设的NVR的WIFI AP建立连接，不与其他NVR的WIFI AP或者非NVR设备的WIFI AP建立连接。In the embodiment of the present application, when the IPC detects that the obtained notification message includes the identifier of the preset WIFI AP, the IPC periodically broadcasts the access request message, where the access request message includes the identifier of the IPC. When the IPC detects that the obtained notification message does not include the identifier of the preset WIFI AP, the IPC does not broadcast the access request message. In this case, the IPC refuses to associate with the device that broadcasts the notification message, and the device association process ends. In this way, it is ensured that the IPC workstation only establishes a connection with the preset NVR WIFI AP, and does not establish a connection with other NVR WIFI APs or non-NVR device WIFI APs.

其中，WIFI AP的标识的表示形式有多种，示例的，可以给NVR的WIFI AP赋予一个编号，WIFI AP的标识可以是该WIFI AP的编号，本申请实施例对WIFI AP的标识的表示形式不作限定。The identifier of the WIFI AP can be represented by a plurality of types. For example, the WIFI AP of the NVR can be assigned a number. The identifier of the WIFI AP can be the number of the WIFI AP, and the identifier of the WIFI AP is represented by the embodiment of the present application. Not limited.

步骤405、当通知消息包括预设的WIFI AP的标识时，IPC对通知消息中的第一接入密钥进行解密，得到第二接入密钥。Step 405: When the notification message includes the identifier of the preset WIFI AP, the IPC decrypts the first access key in the notification message to obtain the second access key.

该通知消息包括第一接入密钥。该第一接入密钥是NVR对接入至WIFI AP的原始接入密钥进行加密后得到的。The notification message includes a first access key. The first access key is obtained by the NVR encrypting the original access key accessed to the WIFI AP.

当IPC检测到获取的通知消息包括预设的WIFI AP的标识时，IPC周期性广播接入请求消息。进一步的，IPC采用预设的解密规则对该通知消息中的第一接入密钥进行解密，得到第二接入密钥。When the IPC detects that the acquired notification message includes the identifier of the preset WIFI AP, the IPC periodically broadcasts the access request message. Further, the IPC decrypts the first access key in the notification message by using a preset decryption rule to obtain a second access key.

步骤406、NVR检测预设标识集中是否存在接入请求消息中的IPC的标识。Step 406: The NVR detects whether there is an identifier of the IPC in the access request message in the preset identifier set.

IPC广播的接入请求消息包括IPC的标识，NVR检测步骤401中建立的预设标识集中是否存在接入请求消息中的IPC的标识。当预设标识集中存在IPC的标识时，NVR才允许对IPC进行接入认证操作。The access request message of the IPC broadcast includes the identifier of the IPC, and the identifier of the IPC in the access request message exists in the preset identifier set established in the NVR detection step 401. When the identifier of the IPC exists in the preset identifier, the NVR allows the access authentication operation for the IPC.

示例的，接入请求消息中的IPC的标识为a3，NVR检测表1所示的预设标识集中存在a3，NVR则允许对IPC进行接入认证操作。又比如，接入请求消息中的IPC的标识为b1，NVR检测表1所示的预设标识集中不存在b1，NVR则禁止对IPC进行接入认证操作。这样一来，能够保证NVR仅允许对其所管理的IPC进行接入认证操作，避免NVR对其余IPC进行接入认证操作，避免了不同监控***的无线信号产生的乱串现象。For example, the identifier of the IPC in the access request message is a3, and the preset identifier shown in the NVR detection table 1 has a3, and the NVR allows the access authentication operation for the IPC. For example, the identifier of the IPC in the access request message is b1, and the preset ID set shown in the NVR detection table 1 does not exist b1, and the NVR prohibits the access authentication operation on the IPC. In this way, it is ensured that the NVR only allows the access authentication operation of the IPC managed by the NVR, and prevents the NVR from performing access authentication operations on the remaining IPCs, thereby avoiding the disorder of the wireless signals generated by different monitoring systems.

此外，NVR可能会获取其他移动设备广播的接入请求消息，此时，该接入请求消息不包括IPC的标识。当NVR获取到该接入请求消息时，确定该接入请求消息不包括IPC的标识，那么NVR禁止对该设备进行接入认证操作，设备认证流程结束。In addition, the NVR may obtain an access request message broadcast by other mobile devices. At this time, the access request message does not include the identifier of the IPC. When the NVR obtains the access request message, it determines that the access request message does not include the identifier of the IPC, and the NVR prohibits the access authentication operation on the device, and the device authentication process ends.

步骤407、当预设标识集中存在接入请求消息中的IPC的标识时，NVR允许对IPC进行接入认证操作。Step 407: When the identifier of the IPC in the access request message exists in the preset identifier set, the NVR allows the access authentication operation to be performed on the IPC.

当预设标识集中存在接入请求消息中的IPC的标识时，NVR则可以确定广播接入请求消息的IPC是该NVR所管理的IPC，NVR则允许对IPC进行接入认证操作，至此，完成预认证过程。When the identifier of the IPC in the access request message exists in the preset identifier, the NVR can determine that the IPC of the broadcast access request message is the IPC managed by the NVR, and the NVR allows the access authentication operation to be performed on the IPC. Pre-certification process.

步骤408、NVR向IPC的标识所指示的IPC发送接入响应消息。Step 408: The NVR sends an access response message to the IPC indicated by the identifier of the IPC.

接入响应消息用于指示NVR允许对IPC进行接入认证操作。The access response message is used to indicate that the NVR allows an access authentication operation for the IPC.

可选的，NVR可以向IPC的标识所指示的IPC发送探测响应帧，该探测响应帧用于指示接入响应消息。Optionally, the NVR may send a probe response frame to the IPC indicated by the identifier of the IPC, where the probe response frame is used to indicate an access response message.

步骤409、NVR基于原始接入密钥对IPC进行接入认证操作。Step 409: The NVR performs an access authentication operation on the IPC based on the original access key.

步骤402中NVR广播的通知消息包括第一接入密钥。The notification message broadcast by the NVR in step 402 includes the first access key.

在本申请实施例中，当IPC接收到NVR发送的接入响应消息后，IPC基于步骤405得到的第二接入密钥进行接入认证操作。In the embodiment of the present application, after the IPC receives the access response message sent by the NVR, the IPC performs an access authentication operation based on the second access key obtained in step 405.

可选的，如图5所示，步骤409可以包括：Optionally, as shown in FIG. 5, step 409 may include:

步骤4091、IPC向NVR发送认证消息。Step 4091: The IPC sends an authentication message to the NVR.

认证消息包括待传输图像数据的加密信息。加密信息用于NVR对IPC传输的待传输图像数据进行解密。认证消息用于指示IPC准备进行接入认证操作。The authentication message includes encrypted information of the image data to be transmitted. The encrypted information is used by the NVR to decrypt the image data to be transmitted transmitted by the IPC. The authentication message is used to indicate that the IPC is ready to perform an access authentication operation.

可选的，IPC可以向NVR发送认证请求帧，该认证请求帧用于指示认证消息。Optionally, the IPC may send an authentication request frame to the NVR, where the authentication request frame is used to indicate the authentication message.

步骤4092、NVR向IPC的标识所指示的IPC发送认证响应消息。Step 4092: The NVR sends an authentication response message to the IPC indicated by the identifier of the IPC.

可选的，NVR可以向IPC的标识所指示的IPC发送认证响应帧，该认证响应帧用于指示认证响应消息。Optionally, the NVR may send an authentication response frame to the IPC indicated by the identifier of the IPC, where the authentication response frame is used to indicate an authentication response message.

步骤4093、IPC向NVR发送关联消息。Step 4093, the IPC sends an association message to the NVR.

关联消息包括步骤405中得到的第二接入密钥。The association message includes the second access key obtained in step 405.

可选的，IPC可以向NVR发送关联请求帧，该关联请求帧用于指示关联消息。Optionally, the IPC may send an association request frame to the NVR, where the association request frame is used to indicate the associated message.

步骤4094、NVR检测关联消息中的第二接入密钥是否与原始接入密钥相同。当第二接入密钥与原始接入密钥相同时，执行步骤4095；当第二接入密钥与原始接入密钥不相同时，执行步骤4096。Step 4094: The NVR detects whether the second access key in the associated message is the same as the original access key. When the second access key is the same as the original access key, step 4095 is performed; when the second access key is different from the original access key, step 4096 is performed.

在步骤405中，IPC采用预设的解密规则对第一接入密钥进行解密，得到的第二接入密钥与原始接入密钥可能相同，也可能不相同。当第二接入密钥与原始接入密钥相同时，NVR向IPC的标识所指示的IPC发送第一关联响应消息，该第一关联响应消息用于指示该IPC的标识所指示的IPC与NVR关联成功；当第二接入密钥与原始接入密钥不相同时，NVR向IPC的标识所指示的IPC发送第二关联响应消息，该第二关联响应消息用于指示该IPC的标识所指示的IPC与NVR关联失败。In step 405, the IPC decrypts the first access key by using a preset decryption rule, and the obtained second access key may or may not be the same as the original access key. When the second access key is the same as the original access key, the NVR sends a first association response message to the IPC indicated by the identifier of the IPC, where the first association response message is used to indicate the IPC indicated by the identifier of the IPC. The NVR association is successful. When the second access key is different from the original access key, the NVR sends a second association response message to the IPC indicated by the identifier of the IPC, where the second association response message is used to indicate the identifier of the IPC. The indicated IPC failed to associate with the NVR.

示例的，原始接入密钥为F1，NVR对原始接入密钥F1进行加密后得到的第一接入密钥为F0，IPC采用预设的解密规则对F0进行解密，得到F2，F2与F1不相同，则设备关联失败。For example, the original access key is F1, and the first access key obtained by the NVR encrypting the original access key F1 is F0, and the IPC decrypts F0 by using a preset decryption rule to obtain F2, F2 and If F1 is different, the device association fails.

步骤4095、当第二接入密钥与原始接入密钥相同时，NVR向IPC的标识所指示的IPC发送第一关联响应消息，该第一关联响应消息用于指示该IPC的标识所指示的IPC与NVR关联成功。Step 4095: When the second access key is the same as the original access key, the NVR sends a first association response message to the IPC indicated by the identifier of the IPC, where the first association response message is used to indicate that the identifier of the IPC is indicated. The IPC is successfully associated with the NVR.

可选的，NVR可以向IPC的标识所指示的IPC发送关联响应帧，该关联响应帧用于指示第一关联响应消息。Optionally, the NVR may send an association response frame to the IPC indicated by the identifier of the IPC, where the association response frame is used to indicate the first association response message.

步骤4096、当第二接入密钥与原始接入密钥不相同时，NVR向IPC的标识所指示的IPC发送第二关联响应消息，该第二关联响应消息用于指示该IPC的标识所指示的IPC与NVR关联失败。Step 4096: When the second access key is different from the original access key, the NVR sends a second association response message to the IPC indicated by the identifier of the IPC, where the second association response message is used to indicate the identifier of the IPC. The indicated IPC failed to associate with the NVR.

可选的，NVR可以向IPC的标识所指示的IPC发送关联响应帧，该关联响应帧用于指示第二关联响应消息。Optionally, the NVR may send an association response frame to the IPC indicated by the identifier of the IPC, where the association response frame is used to indicate the second association response message.

步骤410、当接收到第一IPC发送的故障指示消息后，或者，当接收到第一IPC针对NVR发送的状态检测消息而返回的状态响应消息后，NVR确定第一IPC出现故障。Step 410: After receiving the fault indication message sent by the first IPC, or after receiving the status response message returned by the first IPC for the status detection message sent by the NVR, the NVR determines that the first IPC is faulty.

其中，状态响应消息用于指示第一IPC的设备状态为故障状态，第一IPC为NVR所管理的任一IPC。The status response message is used to indicate that the device status of the first IPC is a fault status, and the first IPC is any IPC managed by the NVR.

可选的，当第一IPC出现故障时，第一IPC可以主动向NVR发送故障指示消息，NVR接收到该故障指示消息后，确定该第一IPC出现故障。此外，NVR也可以定期向第一IPC发送状态检测消息，第一IPC向NVR发送状态响应消息，该状态响应消息用于指示第一IPC的设备状态，可选的，该设备状态可以包括正常状态和故障状态。Optionally, when the first IPC fails, the first IPC may actively send a fault indication message to the NVR, and after receiving the fault indication message, the NVR determines that the first IPC is faulty. In addition, the NVR may also periodically send a status detection message to the first IPC, and the first IPC sends a status response message to the NVR, where the status response message is used to indicate the device status of the first IPC. Optionally, the device status may include a normal status. And fault status.

步骤411、当确定第一IPC出现故障时，NVR将第一IPC的标识从预设标识集中删除，并将第一IPC的备份IPC的标识添加至预设标识集中。Step 411: When it is determined that the first IPC is faulty, the NVR deletes the identifier of the first IPC from the preset identifier set, and adds the identifier of the backup IPC of the first IPC to the preset identifier set.

在本申请实施例中，当NVR所管理的某一IPC出现故障时，NVR可以对出现故障的IPC进行替换，从而保证NVR所管理的IPC均为可用状态。In the embodiment of the present application, when an IPC managed by the NVR fails, the NVR can replace the failed IPC to ensure that the IPC managed by the NVR is in an available state.

示例的，NVR管理5个IPC，这个5个IPC分别是第一IPC、第二IPC、第三IPC、第四IPC和第五IPC。其中，第一IPC的标识为a1，第二IPC的标识为a2，第三IPC的标识为a3，第四IPC的标识为a4，第五IPC的标识为a5。假设第一IPC出现故障，那么NVR将a1从表1所示的预设标识集中删除，并将第一IPC的备份IPC的标识a6添加至表1中，得到的结果如表3所示。这样一来，NVR管理的5个IPC的标识变为：a6、a2、a3、a4和a5。For example, the NVR manages 5 IPCs, which are the first IPC, the second IPC, the third IPC, the fourth IPC, and the fifth IPC, respectively. The identifier of the first IPC is a1, the identifier of the second IPC is a2, the identifier of the third IPC is a3, the identifier of the fourth IPC is a4, and the identifier of the fifth IPC is a5. Assuming that the first IPC is faulty, the NVR deletes a1 from the preset identifier set shown in Table 1, and adds the identifier a6 of the backup IPC of the first IPC to Table 1, and the obtained result is shown in Table 3. In this way, the identifiers of the five IPCs managed by the NVR become: a6, a2, a3, a4, and a5.

另外，第一IPC的数量也可以为多个，也即是，当出现故障的第一IPC有多个时，NVR能够将出现故障的所有第一IPC的标识从预设标记集中删除，并将每个第一IPC的备份IPC的标识添加至预设标识集中。In addition, the number of the first IPC may also be multiple, that is, when there are multiple first IPCs that fail, the NVR can delete the identifiers of all the first IPCs that have failed from the preset mark set, and The identifier of the backup IPC of each first IPC is added to the preset identifier set.

需要说明的是，本申请实施例提供的设备接入方法步骤的先后顺序可以进行适当调整，步骤也可以根据情况进行相应增减，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本申请的保护范围之内，因此不再赘述。It should be noted that the sequence of the steps of the device access method provided by the embodiment of the present application may be appropriately adjusted, and the steps may be correspondingly increased or decreased according to the situation, and any person skilled in the art may be within the technical scope disclosed in the present application. The methods that can be easily thought of as changes are covered by the scope of protection of the present application, and therefore will not be described again.

综上所述，本申请实施例提供的设备接入方法，NVR能够周期性广播通知消息，且当通知消息包括预设的WIFI AP的标识时，IPC周期性广播接入请求消息，该接入请求消息包括IPC的标识。之后，NVR检测预设标识集中是否存在接入请求消息中的IPC的标识，并当预设标识集中存在接入请求消息中的IPC的标识时，允许对IPC进行接入认证操作。整个过程无需手机接收用户触发的操作指令，实现了设备自动预认证，简化了预认证过程。In summary, in the device access method provided by the embodiment of the present application, the NVR can periodically broadcast the notification message, and when the notification message includes the identifier of the preset WIFI AP, the IPC periodically broadcasts the access request message, and the access is performed. The request message includes the identity of the IPC. Then, the NVR detects whether there is an identifier of the IPC in the access request message in the preset identifier set, and allows the access authentication operation to be performed on the IPC when the identifier of the IPC in the access request message exists in the preset identifier set. The whole process does not require the mobile phone to receive the operation instructions triggered by the user, and realizes the automatic pre-authentication of the device, which simplifies the pre-authentication process.
