Problems solved by technology

Although physical sensors directly measure physical phenomena, physical sensors and associated hardware are often costly and sometimes unreliable
Furthermore, when a control system relies on physical sensors for proper operation, the failure of a physical sensor may render such a control system inoperable
Additionally, many physical or virtual sensors cannot measure other physical phenomena

Abstract

The invention discloses a method and a system for using a virtual sensor in Internet of Things. The system comprises a processor and one or more combinations, wherein the processor is used for automatically recognizing one or more virtual sensor models according to a semantic graph and comprises a knowledge domain, and the knowledge domain is used for describing the relation between an observed variable relevant with one or more sensors and unobserved variable relevant with an Internet of Things environment through a link; and one or more combinations are input according to the virtual sensor,and one or more virtual sensor models are deployed in the Internet of Things environment. The system can be adapted to the data detection of equipment in the Internet of Things by virtue of the virtual sensor.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method and system for using a virtual sensor in the Internet of Things. Background technique [0002] In today's society, consumers, business people, educators, and others use a variety of computing systems in a variety of settings. As computing systems proliferate, some computing systems may include and / or be associated with a control system with one or more physical sensors. Physical sensors can be used in many computers, machines and / or products to measure and monitor physical phenomena such as lighting or temperature. Physical sensors can directly measure physical phenomena and convert these measurements into measurement data for further processing by control systems. Although physical sensors directly measure physical phenomena, physical sensors and associated hardware are often costly and sometimes unreliable. Furthermore, when a control system relies on...
