摘要
随着物联网以及工业大数据技术的发展,对于将现场设备的数据及功能直接集成进信息系统中,有了越来越迫切的需求。目前采用网关作为集成点或者在资源约束的现场设备上实现基于SOAP的Web Services的方法,都有一定的不足。为解决这些不足,提出了一种混合的解决方案,即在资源约束的现场设备上实现基于CoAP的RESTful web services,减轻了对现场设备的资源压力,在网关实现基于CoAP的RESTful web services与基于SOAP的Web Services的映射转换,有效实现与已有的传统web services的集成。采用该方法改造已有的传统现场监控应用,验证了方法的适用性。
With the development of Io T and industrial big data,it has more and more requirements to integrate data and functions of field devices directly into IT infrastructure. Gateway between IT infrastructure and field devices or implementing web services based on SOAP in field devices are two candidate methods,but severe defects are exists in them.Aiming to solve the problems,a hybrid method is proposed.In field devices,RESTful web services based on CoAP is implemented,which has reduced the resource burden.In the gateway,the mapping between RESTful web services and web services based on SOAP is used to integrate the field devices with traditional web services.Through experiments on prototype system,the availability of the architecture has been approved
