One of the challenges facing the current development of Internet of Things (IOT) is the heterogeneity of devices. A wide variety of devices may own a wide variety of underlying communication protocols and data transmission protocols. If we design and implement different management solutions for different devices, the cost is too much and the management is too inconvenient. In this paper, all the sensor devices and sensing data will be regarded as unified resources and identified by unique Uniform Resource Identifier (URI). We propose a device management system based on REST which can shield the diversity of underlying protocols and manage all the devices in internet of things service platform uniformly. Two major modules in this system are the data upload module and the device control module. The former one accomplishes data obtainment and data visualization. The latter one accomplishes modification of device state. This paper gives the implementation details of these two modules respectively in the prototyping system and the function and performance verification through experiments.
