Control method and system for temperature-sensing variable frequency fan

Abstract

The invention discloses a control method for a temperature-sensing frequency conversion fan, which belongs to a fan control method. The method includes the following steps: step A, system startup, the temperature sensor collects the current temperature value, and the first collected The temperature value is transmitted to the control unit as the first temperature value; step B, the temperature sensor continuously collects the current temperature value according to the time interval, and transmits it to the control unit successively; step C, the control unit uses the first temperature value as a reference, when receiving again When the temperature value is reached, it is compared with the first temperature value, and if it is lower than the first temperature value, the fan motor is controlled to reduce the fan speed. The method takes the ambient temperature where the fan is located as a temporary reference value, and adjusts the speed of the fan according to the temperature change after the fan is started, so that the air output of the fan is consistent with the curve change of the indoor temperature, effectively improving the human body. And there is no need to preset the threshold and wind speed mode, the control method is simple and effective.

Description

technical field [0001] The present invention relates to a fan control method, and more specifically, the present invention mainly relates to a control method for a temperature-sensitive frequency conversion fan. Background technique [0002] At present, the fan control methods on the market are single, and most of them can only adjust the air output of the fan by controlling the speed of the motor. Even smart fans can only control the speed of the fan according to the preset mode and temperature value, or Remote control is achieved through the Internet of Things control, but it is not conducive to improving the comfort of the human body for the human body, so it is necessary to do further research and improvement on the control method of the fan. Contents of the invention [0003] One of the objectives of the present invention is to provide a control method for temperature-sensitive variable frequency fans in order to solve the technical problems in the prior art such as t...
