Abstract

The invention discloses a fan control method and system. The fan control method comprises the following steps: receiving coordinates of a target at the current moment, sent from a server, in a preset coordinate system, wherein the coordinates of the target at current moment in the preset coordinate system are obtained by calculating by the server according to the preset coordinate system and RSS data of the target at the current moment in a radio frequency sensing network; calculating according to the coordinates of the target at the current moment in the preset coordinate system and coordinates of a fan, stored in advance, in the preset coordinate system to obtain a relative distance and a relative angle of the target at the current moment and the fan; outputting first pulse width according to the relative distance, and outputting second pulse width according to the relative angle; and regulating the rotation speed of a motor of the fan according to the first pulse width, and regulating the rotation angle of the motor of the fan according to the second pulse width. The fan control method and system can know the requirements of a user actively, and thus the requirement on comfort of air from the fan of the user can be met to the greatest extent.

Description

technical field [0001] The present invention relates to the field of smart home technology, in particular to a fan control method and system. Background technique [0002] Compared with air conditioners, fans have the characteristics of environmental protection, energy saving, low price and high cost performance, so they will still exist widely in the future. However, many existing traditional fans use fixed physical buttons on the fan or short-distance remote controllers to realize operations such as starting, stopping, and speed adjustment of the fan. Such settings make it impossible for the fan to supply air according to the actual location of the user. [0003] There are two main sensing methods for smart fans currently available. One is infrared sensing, which detects the human body through infrared sensing, and further drives the motor of the fan to supply air to the human body; the other is temperature sensing, which detects the human body through infrared sensing. T...
