The two technical principles are similar: the distance measurement and the angle measurement are completed by using the UWB antenna array inside the UWB mobile phone and the UWB chip built in the intelligent household appliance, so that the relative position of the mobile phone and the intelligent household appliance can be obtained. When the mobile phone points at a certain household appliance (distance or other more limiting conditions can be increased), the mobile phone operator is determined to want to control the household appliance, and the control interface of the household appliance can be automatically switched to on the mobile phone screen.

The intelligent household remote control scheme represented by the existing 'one-finger connection' and 'one-key connection' schemes has a problem: and each intelligent household appliance is required to have an independent UWB chip, so that the cost is high, and the compatibility of the existing product is poor. Under this kind of scheme, to the household electrical appliances of not integrating the UWB chip, can utilize external UWB module to improve. The external UWB module (millet is named as UWB mate) is integrated with a UWB chip, but each household appliance to be remotely controlled needs to be connected with the equipment, so that the cost is high, and the compatibility is not good.
