Abstract
本实用新型公开了一种可根据外围温度的变化自动调整转速的电器温控智能风扇，风扇中安装有电机和与电机串接的电机驱动部件，电机驱动部件的输入端连接CPLD中心控制器，CPLD中心控制器的输出连接温度显示器，温度传感器、拨动开关和时钟的输出分别连接CPLD中心控制器的输入。当CPLD温度升高，风扇的转速便提高；当CPLD温度降低，风扇的转速便降低。可在不同的温度设置相应的转速，当CPLD温度达到某一温度时才全速转动，当CPLD温度低于某一温度时风扇停止转动，既提高了散热效果，又减少了耗电量，也减少了因风扇高速转动而产生的噪音，具有逻辑性强、响应时间快，程序不容易跑飞、体积小和成本低等优点。
The utility model discloses an electric appliance temperature-controlled intelligent fan which can automatically adjust the rotating speed according to the change of the peripheral temperature. A motor and a motor driving part connected in series with the motor are installed in the fan. The input end of the motor driving part is connected to a CPLD central controller. The output of the CPLD central controller is connected to the temperature display, and the outputs of the temperature sensor, toggle switch and clock are respectively connected to the input of the CPLD central controller. When the temperature of the CPLD increases, the speed of the fan increases; when the temperature of the CPLD decreases, the speed of the fan decreases. The corresponding speed can be set at different temperatures. When the temperature of the CPLD reaches a certain temperature, it will rotate at full speed. When the temperature of the CPLD is lower than a certain temperature, the fan will stop rotating, which not only improves the heat dissipation effect, but also reduces power consumption. It eliminates the noise caused by the high-speed rotation of the fan, and has the advantages of strong logic, fast response time, program is not easy to run away, small size and low cost.
Description
Technical field
The utility model relates to a kind of fan, especially can adjust the fan of rotating speed according to the variation of peripheral temperature automatically.
Background technique
Fan can be used for the heat radiation and the refrigeration of equipment such as communication apparatus, stereo set, refrigerator refrigerator, household electric appliance, computer, has both improved radiating effect, has reduced power consumption again, has triple advantages of heat radiation, energy-conservation and noise reduction.Rotation speed of the fan commonly used is at present controlled by speed regulator, as required by manually-operable.Existing intelligent fan rotating speed is that single-chip microcomputer is installed in controller mostly, and its defective is: volume is big, logicality difference and response time are slow, can't satisfy the requirement of user to the fan rotational stability.
CPLD (CPLD, down together) is the higher logic component of a kind of conformability, belongs to the large-scale integrated circuit (LSI) scope, is used widely in the controller field at present.
Summary of the invention
The purpose of this utility model is for overcoming the deficiencies in the prior art, a kind of electrical equipment temperature control intelligent fan based on CPLD is provided, can adjusting rotation speed of the fan automatically with the variation of fan ambient temperature.
The technical solution adopted in the utility model is: be equipped with in the fan motor and with the motor driving parts of motor joining, the input end of motor driving parts connects the CPLD master controller, the output of CPLD master controller connects temperature indicator, and the output of temperature transducer, toggle switch and clock is connected the input of CPLD master controller respectively.
The beneficial effects of the utility model are:
1, can adjust rotating speed voluntarily according to system temperature, when the rising of CPLD temperature, the rotating speed of fan just improves; When the reduction of CPLD temperature, the rotating speed of fan just reduces.
2, can corresponding rotating speeds be set at different ambient temperatures, when reaching a certain temperature, the CPLD temperature just rotates at full speed, when the CPLD temperature is lower than a certain temperature, fan stops operating, so both improved radiating effect, reduce power consumption again, also reduced the noise that produces because of the fan high speed rotating.
3, can realize LCD (liquid crystal display, the down together) demonstration in real time of fan ambient temperature.
4, since the utility model based on CPLD, logicality is strong, the response time is fast so have, program is not easy to run and flies, volume is little and low cost and other advantages, overall price/performance ratio is better than existing SCM Based intelligent fan.
