Signal conversion device and smart home network system using the same

摘要

A smart home network system includes a number of traditional home devices having wireless communication function, a smart gateway, and a plurality of signal conversion devices. When the smart gateway wants to control a traditional home device, the smart gateway sends a cable control signal to a related signal conversion device in the area where the target traditional home device is placed. The related signal conversion device receives the cable control signals from the smart gateway, and converts the cabled control signal into a wireless control signal conforming to the wireless communication function type of the target tradition home device, then transmits the wireless control signal to the target traditional home device. Therefore, the traditional home devices with wireless communication function can be connected into the system, and be controlled by the smart gateway.

主权项

1. A smart home network system comprising a plurality of traditional home devices having wireless communication function, a smart gateway, and a plurality of signal conversion devices, each of the signal conversion device comprising:
a first wired communication module configured to receive a cable control signal for controlling a target traditional home device from the smart gateway, wherein the cable control signal contains a UID code and a wireless communication function type of the target traditional home device; a conversion module configured to read the wireless communication function type of the target traditional home device contained in the cable control signal, and converts the cable control signal into a wireless control signal conforming to the wireless communication function type; a first wireless communication module configured to wirelessly transmit the wireless control signal to the target traditional home device; and the smart gateway comprising: a storage module storing a mapping list, wherein the mapping list records configuration information of each traditional home device and each signal conversion device in the system, and the configuration information contains region codes representing areas where the home devices and the signal conversion devices are placed, UID codes of each home device and each signal conversion device, and wireless communication function type of each traditional home device; an analysis module configured to read the UID codes of the target traditional home device and a related signal conversion device in the area where the target traditional home device is placed, and the wireless communication function type of the target traditional home device from the configuration information recorded in the mapping list; a control module configured to generate the cable control signal for controlling the target traditional home device, wherein the cable control signal further contains a UID code of the related signal conversion device; and a second wired communication module configured to transmit the cable control signal to the related signal conversion device.
