Fuente: Wipo "IOT" The invention discloses a system, device and method for accessing an Internet of Things IOT facility into a home gateway. The method comprises the following steps: an IOT bridge downloads multiple communication protocol detectors and multiple communication protocol converters from an IOT bridge cloud server; the IOT bridge determines communication protocols supported by the home gateway; the IOT bridge acquires the communication protocols of multiple IOT facilities in a home network according to the multiple downloaded communication protocol detectors; the IOT bridge respectively converts the acquired communication protocol of each IOT facility into the communication protocol supported by the home gateway according to multiple downloaded communication protocol converters; and the IOT bridge respectively bridges each IOT facility after the communication protocol conversion into the logic IOT facility with the communication protocol supported by the home gateway. Through the adoption of the system, device and method disclosed by the embodiment of the invention, the interconnection and inter communication between the IOT facilities and between the IOT facility and the home gateway are realized.
