Abstract
A fan, and a control system and method therefor, wherein the system comprises a wearable device (100) and a fan (200). The fan (200) communicates with the wearable device (100). The wearable device (100) is used for detecting body parameters of a user to determine whether the user falls asleep, generating a sleep wind mode instruction to the fan (200). The fan (200) enters a sleep wind mode after receiving the sleep wind mode instruction, obtains a sleep wind control curve, and adjusts operating parameters according to the sleep wind control curve. The fan control system can adjust the running gear of the fan according to the sleep wind control curve after the user falls asleep, and avoids interference factors, thereby improving the control precision of the fan and improving user experience.
