Description

实现Zigbee设备远程升级的方法、装置及网络系统Method, device and network system for realizing remote upgrade of Zigbee equipment

技术领域 technical field

本发明涉及通信技术领域，特别涉及一种实现Zigbee设备远程升级的方法、装置及网络系统。The invention relates to the field of communication technology, in particular to a method, device and network system for realizing remote upgrade of Zigbee equipment.

背景技术 Background technique

机器通信(Machine-to-Machine Communications，M2M)是一种以机器智能交互为核心的、网络化的应用与服务，通过在机器内部嵌入无线或有线通信模块以及应用处理逻辑，实现无需人工干预的数据通信，以便满足用户对监控、指挥调度、数据采集和测量等方面的信息化需求。图1示出了一种典型的M2M系统架构，其中，各种M2M终端(如传感器、微控制器等)通过传感网络技术连接到M2M网关，再通过M2M网关利用远程接入技术(如2G/3G无线蜂窝网络技术、非对称数字用户环路(Asymmetric DigitalSubscriber Line，ADSL)技术)连接到M2M业务平台，而各种应用(如电力抄表、智能交通等)则是通过M2M业务平台获取M2M终端采集的数据或者对M2M终端进行远程的控制和管理。Machine-to-Machine Communications (M2M) is a networked application and service centered on machine intelligence interaction. By embedding wireless or wired communication modules and application processing logic inside the machine, it can achieve Data communication, in order to meet users' informatization needs for monitoring, command and dispatch, data collection and measurement. Figure 1 shows a typical M2M system architecture, in which various M2M terminals (such as sensors, microcontrollers, etc.) /3G wireless cellular network technology, asymmetric digital subscriber loop (Asymmetric Digital Subscriber Line, ADSL) technology) is connected to the M2M service platform, and various applications (such as power meter reading, intelligent transportation, etc.) are obtained through the M2M service platform. The data collected by the terminal or the remote control and management of the M2M terminal.

远程设备管理是M2M系统的一个重要功能，远程设备管理是指M2M应用或M2M服务提供商需要通过M2M业务平台以及M2M网关远程地对处于末梢传感网络中的M2M终端进行日常管理和维护，具体包括对M2M终端的远程配置管理、性能管理、故障管理、软件/固件升级等多个方面的功能。这些设备管理功能需要通过M2M业务平台和M2M网关中的设备管理能力组件来配合完成。Remote device management is an important function of the M2M system. Remote device management means that M2M applications or M2M service providers need to remotely manage and maintain M2M terminals in the peripheral sensor network through M2M service platforms and M2M gateways. Including remote configuration management of M2M terminals, performance management, fault management, software/firmware upgrade and many other functions. These device management functions need to be completed through cooperation between the M2M service platform and the device management capability components in the M2M gateway.

现有技术中，基于广域网的远程设备管理技术主要有开放移动联盟(Open Mobile Alliance，OMA)所定义的设备管理(Device Management，DM)规范(以下简称DM)，以及宽带论坛(Broadband Forum)所定义的TR069规范(以下简称TR069)。其中，DM主要应用于移动网络环境(如2G/3G蜂窝网络)中，而TR069则主要用于固定宽带网络环境(如ADSL)，二者都能提供对单个设备的远程管理维护功能。而在传感网络中，目前M2M终端常用的一种技术是Zigbee技术，它不仅提供了本地传感网络中设备之间的基本通信能力，也提供了一定的设备管理能力，比如固件升级(Zigbee OTAUpgrade)。Zigbee技术支持同时对多个Zigbee网络设备进行固件升级操作，也提供了多种固件升级的执行方式。In the prior art, remote device management technologies based on WAN mainly include the Device Management (DM) specification (hereinafter referred to as DM) defined by the Open Mobile Alliance (OMA), and the Broadband Forum (Broadband Forum) The defined TR069 specification (hereinafter referred to as TR069). Among them, DM is mainly used in mobile network environment (such as 2G/3G cellular network), while TR069 is mainly used in fixed broadband network environment (such as ADSL), both of which can provide remote management and maintenance functions for a single device. In the sensor network, a technology commonly used by M2M terminals is Zigbee technology, which not only provides basic communication capabilities between devices in the local sensor network, but also provides certain device management capabilities, such as firmware upgrades (Zigbee OTA Upgrade). Zigbee technology supports firmware upgrade operations for multiple Zigbee network devices at the same time, and also provides a variety of firmware upgrade execution methods.

现在，M2M业务平台中的设备管理能力组件能够采用上述基于广域网的远程设备管理技术(DM或者TR069)对M2M网关进行远程管理；M2M网关中的设备管理能力组件可以采用上述传感网络设备管理技术(Zigbee)对传感网络末梢的M2M终端进行本地管理。然而，由于广域网的远程设备管理技术和传感网设备管理技术存在的差异性，M2M应用或M2M服务提供商却无法利用基于广域网的设备管理技术通过M2M业务平台和M2M网关直接对M2M终端进行管理。Now, the device management capability component in the M2M service platform can use the above-mentioned WAN-based remote device management technology (DM or TR069) to remotely manage the M2M gateway; the device management capability component in the M2M gateway can use the above-mentioned sensor network device management technology (Zigbee) Locally manage M2M terminals at the end of the sensor network. However, due to the differences between the remote device management technology of the WAN and the device management technology of the sensor network, M2M applications or M2M service providers cannot use the device management technology based on the WAN to directly manage M2M terminals through the M2M service platform and the M2M gateway. .

现有技术提供一种使用简单网络管理协议(Simple Network ManagementProtocol，SNMP)协议对M2M终端进行远程管理的方法，如图2所示，其中，SNMP管理站上的管理应用模块通过SNMP协议将设备升级请求发送到接入点(Network Access Point，AP)上的简单网络管理协议代理SNMP Agent，该设备升级请求被转发到M2M终端上的SNMP Agent，由M2M终端上的SNMP Agent与本地建立的SNMP管理信息库(MIB)进行信息交互，从而实现对M2M终端进行固件升级。The existing technology provides a method for remotely managing M2M terminals using the Simple Network Management Protocol (SNMP) protocol, as shown in Figure 2, wherein the management application module on the SNMP management station upgrades the device through the SNMP protocol The request is sent to the simple network management protocol agent SNMP Agent on the access point (Network Access Point, AP), and the device upgrade request is forwarded to the SNMP Agent on the M2M terminal, which is managed by the SNMP Agent on the M2M terminal and the locally established SNMP The information base (MIB) performs information exchange, so as to realize the firmware upgrade of the M2M terminal.

现有技术具有如下缺点：Prior art has following shortcoming:

现有技术需要M2M终端上具有SNMP Agent和SNMP管理信息库(MIB)，即需要M2M终端支持SNMP协议，但是现已应用于传感网络的大量M2M终端并不支持SNMP协议，因此，需要进行固件升级时，对现已应用的M2M终端的改动很大，提高了运营成本。The existing technology requires the M2M terminal to have SNMP Agent and SNMP Management Information Base (MIB), that is, the M2M terminal needs to support the SNMP protocol. However, a large number of M2M terminals that have been applied to the sensor network do not support the SNMP protocol. During the upgrade, the existing M2M terminals have been greatly changed, which increases the operating cost.

In addition, for the multiple executable nodes defined under the <x>/Download/Operations and <x>/Delivered/Operations nodes, which represent multiple upgrade methods, a single executable node can be used to describe multiple related attribute nodes. Differentiate between different execution methods (similar to the design principle of the <x>/Recover node).

参阅图5，本发明实施例提供一种实现Zigbee设备远程升级的方法，该方法中，设备管理服务器与网关之间采用DM协议，该方法具体包括：Referring to Fig. 5, the embodiment of the present invention provides a kind of method that realizes Zigbee device remote upgrade, and in this method, adopts DM agreement between equipment management server and gateway, this method specifically comprises:

501、Zigbee设备确定本地网络中对其进行管理的网关。501. The Zigbee device determines a gateway that manages it in the local network.

具体可以有如下两种方式：Specifically, there are two ways:

第一种方式：Zigbee设备中预先配置了网关的IEEE地址(每个IEEE地址唯一标识一个网关)，Zigbee设备确定该IEEE地址所标识的网关为管理自己的网关，Zigbee设备还可以根据该IEEE地址发送Zigbee设备对象网络地址请求ZDO Nwk_addr_req请求，从接收的响应消息中获取网关的网络地址，以便利用该网络地址后续与所述网关进行管理信息交互。The first way: the IEEE address of the gateway is pre-configured in the Zigbee device (each IEEE address uniquely identifies a gateway), the Zigbee device determines that the gateway identified by the IEEE address is the gateway that manages itself, and the Zigbee device can also use the IEEE address Send the Zigbee device object network address request ZDO Nwk_addr_req request, obtain the network address of gateway from the response message received, so that utilize this network address to carry out management information interaction with described gateway subsequently.

第二种方式：如果Zigbee设备中没有预先配置网关的IEEE地址则向本地网络广播Zigbee设备对象匹配描述请求ZDO Match_Desc_req请求，其中携带固件升级簇标识OTA Cluster ID，该标识表明查找支持Zigbee固件升级功能的网关，本地网络中的网关收到该请求后，向所述Zigbee设备发送Zigbee设备对象匹配描述响应ZDO Match_Desc_rsp消息，其中携带所述网关的网络地址，然后所述Zigbee设备可以根据所述网关的网络地址，向所述网关发送Zigbee设备对象IEEE地址请求ZDO IEEE_addr_req请求，如果Zigbee设备接收到网关的IEEE地址，则确认该网关是管理自己的网关。The second way: If the IEEE address of the gateway is not pre-configured in the Zigbee device, broadcast the Zigbee device object matching description request ZDO Match_Desc_req request to the local network, which carries the firmware upgrade cluster identifier OTA Cluster ID, which indicates that the search supports the Zigbee firmware upgrade function After the gateway in the local network receives the request, it sends the Zigbee device object matching description response ZDO Match_Desc_rsp message to the Zigbee device, which carries the network address of the gateway, and then the Zigbee device can according to the gateway's Network address, send Zigbee equipment object IEEE address request ZDO IEEE_addr_req request to described gateway, if Zigbee equipment receives the IEEE address of gateway, then confirm that this gateway is the gateway that manages oneself.

502、网关利用Zigbee设备管理命令获取Zigbee设备的详细信息，以便配置如图4所示的管理树中./GW./DevList节点上的信息。502. The gateway obtains the detailed information of the Zigbee device by using a Zigbee device management command, so as to configure the information on the ./GW./DevList node in the management tree shown in FIG. 4 .

具体的，网关向Zigbee设备发送设备信息查询请求消息，例如Zigbee设备对象节点描述请求ZDO Node_Desc_req、Zigbee设备对象简单描述请求ZDO Simple_Desc_req消息等等，用于请求获取Zigbee设备的详细信息；Zigbee设备向网关发送响应消息，该响应消息中携带Zigbee设备的生产商标识、设备类型等设备描述信息。网关再向Zigbee设备发送Zigbee簇库属性读取ZCL Read_Attributes请求消息，该消息中携带当前固件版本CurrentFirmwareVersion参数，以请求查询Zigbee设备的固件版本；该Zigbee设备向网关发送响应消息，该响应消息中携带所述Zigbee设备的固件版本信息。Specifically, the gateway sends a device information query request message to the Zigbee device, such as a Zigbee device object node description request ZDO Node_Desc_req, a Zigbee device object simple description request ZDO Simple_Desc_req message, etc., for requesting the detailed information of the Zigbee device; A response message is sent, and the response message carries device description information such as the manufacturer identification and device type of the Zigbee device. The gateway then sends the Zigbee cluster library attribute to the Zigbee device to read the ZCL Read_Attributes request message, which carries the current firmware version CurrentFirmwareVersion parameter to request the firmware version of the Zigbee device; the Zigbee device sends a response message to the gateway, and the response message carries The firmware version information of the Zigbee device.

503、网关将Zigbee设备的详细信息配置到管理树的相关节点中，具体的，配置到如图4所示的MO管理树中./GW下DevList节点中。503. The gateway configures the detailed information of the Zigbee device to relevant nodes of the management tree, specifically, to the DevList node under ./GW in the MO management tree as shown in FIG. 4 .

504、网关利用远程设备管理协议，与设备管理服务器间建立设备管理会话。504. The gateway uses the remote device management protocol to establish a device management session with the device management server.

具体的，网关接收到来自设备管理服务器的设备管理通知消息，然后与该设备管理服务器建立设备管理会话，并通过替换Relplace命令提供网关自身的基本信息(./DevInfo节点中记录的信息)给所述设备管理服务器；设备管理服务器通过获取Get命令获取网关的详细信息(./DevDetail节点中记录的信息)，以及与所述网关相连的所有Zigbee设备的信息(./GW/DevList/节点中记录的信息)。Specifically, the gateway receives the device management notification message from the device management server, then establishes a device management session with the device management server, and provides the basic information of the gateway itself (information recorded in the ./DevInfo node) to all The device management server; the device management server obtains the detailed information of the gateway (the information recorded in the ./DevDetail node) by obtaining the Get command, and the information of all Zigbee devices connected to the gateway (recorded in the ./GW/DevList/ node Information).

505、设备管理服务器通过Replace命令在网关管理树的相关节点中配置新固件基本信息和新固件所适用的Zigbee设备的范围描述信息。505. The device management server configures the basic information of the new firmware and the range description information of the Zigbee devices applicable to the new firmware in the relevant nodes of the gateway management tree through the Replace command.

具体的，在PkgName节点中配置新固件名称、在PkgVersion节点中配置版本、在ApplyTo中配置新固件所适用的Zigbee设备范围描述信息。Specifically, the new firmware name is configured in the PkgName node, the version is configured in the PkgVersion node, and the Zigbee device range description information applicable to the new firmware is configured in ApplyTo.

506、设备管理服务器利用所建立的设备管理会话，通过网关对Zigbee设备进行远程固件升级操作。506. The device management server uses the established device management session to perform a remote firmware upgrade operation on the Zigbee device through the gateway.

该步骤请参见后续实施例的详细描述。Please refer to the detailed description of the subsequent embodiments for this step.

需要说明的是，由于远程设备管理协议(DM/TR069)与Zigbee协议二者在参数命名、数据类型上并非完全兼容，因此步骤503中网关将Zigbee设备的详细信息配置到管理树的相关节点时需要执行参数名称和数据类型的转换工作，表1列举了固件升级所需要支持的参数的转换映射关系，其中，统一资源名称(Uniform Resource Name，URN)是一种具体有特殊限定格式的字符串类型。It should be noted that, since the remote device management protocol (DM/TR069) and the Zigbee protocol are not fully compatible in parameter naming and data types, when the gateway configures the detailed information of the Zigbee device to the relevant nodes of the management tree in step 503 It is necessary to perform the conversion of parameter names and data types. Table 1 lists the conversion and mapping relationships of parameters that need to be supported by firmware upgrades. Among them, the uniform resource name (Uniform Resource Name, URN) is a string with a specific and limited format. type.

表1Table 1

图6示出了设备管理服务器通过网关实现对Zigbee设备远程升级的一种方式，即普通升级方式，普通升级方式是指各Zigbee设备在获得新固件后立即升级，而且与其他适用于新固件的Zigbee设备的升级时间无关，具体包括：Figure 6 shows a way for the device management server to remotely upgrade Zigbee devices through the gateway, that is, the common upgrade method. The common upgrade method means that each Zigbee device is upgraded immediately after obtaining new firmware, and is compatible with other firmware that is applicable to the new firmware.

The main difference is that the nodes in the TR069 protocol do not have executable attributes, that is, they cannot trigger a certain node (such as ZigbeeFw/<x >/Download/Operations/Download) to instruct the gateway to perform the corresponding operation. In order to instruct the gateway to perform corresponding operations, the TR069 protocol carries a series of dedicated device management commands (such as Download, Reboot, ...) in the device management message, or encapsulates it in the new firmware file downloaded by the gateway. Figure 11 is the structure of the download file supported by the TR069 protocol. When the file is used to package the new firmware to be upgraded, the device management command list related to the file can carry a series of descriptions and commands related to device firmware upgrade, including File usage, firmware version information, applicable device version range, etc., can be expanded to include Zigbee device range commands applicable to the new firmware, new firmware upgrade method commands, etc. in the new firmware file.
