Switch controlling system and switch controlling method of smart appliances

A switch controlling method of smart appliances, comprising the following steps:

• disposing a plurality of switch devices respectively at different positions in a space, and connecting each of the switch devices to a plurality of electronic devices disposed in the space;
• obtaining spatial information of the space to establish a spatial database by a central control device;
• holding a beacon device and movably locating in the space;
• outputting a beacon signal by the beacon device;
• wirelessly connecting the switch device entering within a distance range from the beacon device with the beacon device, receiving the beacon signal from the beacon device by the switch device, and outputting a distance determined signal according to the beacon signal by the switch device;
• and
• looking up the spatial information from the spatial database based on the distance determined signal, determining a position of the beacon device relative to the electronic devices in the space according to the spatial information, and selectively switching the switch devices based on the position to control the electronic devices, by the central control device.
