Abstract: 귀선전류를이용한무전원센서태그가제공된다. 본발명의실시예에따른센서태그는, 전차선의귀선전류를이용하여전기에너지를생성하는전원부, 전원부에서생성된전기에너지를충전하는충전부, 충전부에의해충전된전기에너지를이용하여센싱을통해데이터를생성하고생성된데이터를무선으로전송하는센서부를포함한다. 이에의해, 열차선로에흐르는귀선전류를에너지원으로센서태그에전원을공급할수 있게되어, 기존구조물의변경이나추가설치없이무전원센서태그를쉽게구축할수 있게된다.

Abstract: An open M2M system and a method are provided. A method for managing resources according to an exemplary embodiment of the present invention includes: registering resources existing in a first domain at a second domain; and discovering metadata of a desired resource in the second domain. Accordingly, information management and sharing can be optimized, and registration and discovery of resources can be supported to be performed on a global scale.
