LwM2M在智能电表通信模块上的应用

Application of LwM2M in Communication Module of Smart Meter

通信模块是智能电表重要的数据传输单元,在目前的电力系统中仍缺少有效的通信模块管理方法。该文利用LwM2M协议可容纳广泛的应用程序的特点,提出了一种智能电表通信模块的管理方法。该方法将LwM2M客户端部署到通信模块中,将通信模块数据抽象化为LwM2M对象实例以供LwM2M服务端访问,从而实现通信状态的监测及通信模块软件的在线升级。测试结果表明,该方法能简单、可靠、高效地管理通信模块,功能可扩展性强。

The communication module is an important data transmission unit of the smart meter,and an effective communication module management method is still lacking in the current power system. This paper proposes a management method of the communication module of the smart meter by using the feature that the LwM2M protocol can accommodate a wide range of applications. The method deploys the LwM2M client into the communication module,abstracts the communication module data into LwM2M object instances for the LwM2M server to access,so as to realize the monitoring of the communication status and the online upgrade of the communication module software. The test results show that the method can manage the communication module simply,reliably and efficiently,and has strong function expansibility.
