Realization of open online control of diverse in-situ sensors is a challenge. This paper proposes a Cyber-Physical Geographical Information Service-enabled method for control of diverse in-situ sensors, based on location-based instant sensing of sensors, which provides closed-loop feedbacks. The method adopts the concepts and technologies of newly developed cyber-physical systems (CPSs) to combine control with sensing, communication, and computation, takes advantage of geographical information service such as services provided by the Tianditu which is a basic geographic information service platform in China and Sensor Web services to establish geo-sensor applications, and builds well-designed human-machine interfaces (HMIs) to support online and open interactions between human beings and physical sensors through cyberspace. The method was tested with experiments carried out in two geographically distributed scientific experimental fields, Baoxie Sensor Web Experimental Field in Wuhan city and Yemaomian Landslide Monitoring Station in Three Gorges, with three typical sensors chosen as representatives using the prototype system Geospatial Sensor Web Common Service Platform. The results show that the proposed method is an open, online, closed-loop means of control.
实现对各种现场传感器的开放式在线控制是一项挑战。本文提出了一种基于网络物理地理信息服务的方法，用于控制各种现场传感器，该方法基于传感器的基于位置的即时传感，提供闭环反馈。该方法采用新开发的网络物理系统（CPS）的概念和技术，将控制与传感、通信和计算相结合，利用地理信息服务（如中国基本地理信息服务平台天地图提供的服务和传感器网络服务）来建立地理传感器应用，并构建精心设计的人机界面（HMI），以支持人类通过网络空间与物理传感器之间的在线和开放式交互。该方法在两个地理上分布的科学实验场进行了测试，即武汉市的宝协传感器网络实验场和三峡的野茅砭滑坡监测站，并使用地理空间传感器网络公共服务平台原型系统选择了三种典型传感器作为代表。结果表明，所提出的方法是一种开放、在线、闭环的控制手段。
