针对物联网工作流系统的构建，文中提出一种通用的实现方法。遵照YD/T 2437—2012标准给出的框架，把网络/业务网络层中的应用支撑网，作为支撑虚拟的覆盖网络的基础。在此框架中，覆盖网络被视为一种物联网应用开发的支持平台。在此基础上，参照工作流管理联盟对于工作流系统框架建立的要求，对该系统的建立、运行和实现的三个阶段及其内部结构进行了设计。通过在此框架中的层次结构、功能及其相互关系等方面的问题逐一得到处理，这些方法得到了进一步的说明。%In order to construct the workflow system on the Internet of Things ( IoT) ,a general approach is put forward as the way of im-plementing it. According to given framework under the standard YD/T 2437—2012,the application supporting network in network layer/business network layer are regarded as the basis of supporting virtual overlay network. In this framework,the overlay network is consid-ered a kind of the Internet of Things platform for the support of application development. And on this basis,according to the requirements of Workflow Management Coalition( WfMC) to establish workflow system framework,three stages of the system ( the establishment,op-eration and implementation) and their internal structure are designed. These methods receive further explanation by problems with hierar-chy,functions and their mutual relations in the framework to be tackled one by one.
