Abstract
The invention discloses an intelligent computerized fan control method implemented via intelligent fans, control chips, a temperature and speed detection control module, a warning circuit and a power supply. The method includes the steps: a device is initialized while a MCU (micro control unit) is in the default mode of no warning, and control chips transmits PWM (pulse width modulation) signals to the intelligent fans; the intelligent fans regulate their speeds according to the PWM signals, and the control chips detect FG signals returned by the intelligent fans to acquire current speeds of the intelligent fans; the control chips detect a current temperature and transmit the FG signals and temperature signals to the MCU; the MCU compares the temperatures and the speeds to judge whether the current operating modes of the intelligent fans are reasonable or not and perform corresponding treatments. Compared with the prior art, the method has the advantages such as reasonable design and convenience of use; the cooling problem of a system is effectively solved, and normal and reasonable operation of a cooling circuit can be guaranteed.
Description
Technical field
The present invention relates to control with computational intelligence technical field, specifically a kind of computer intelligence control method for fan.
Background technology
MCU (Micro Control Unit) Chinese is micro-control unit, claim again one chip microcomputer or single-chip microcomputer, refer to appearance and development thereof along with large scale integrated circuit, by the CPU of computing machine, RAM, ROM, timer conter and multiple I/O Interface integration on a slice chip, form the computing machine of chip-scale, for different application scenarios, do various combination and control.
Current, along with electronic product function is tending towards variation, device layout is tending towards densification, power consumption inevitably increases, and also exposed day by day is out for the heat problem that meanwhile too high power consumption is brought.Too much heat will affect the integral working of product.If the heat producing can not get effective processing, along with the accumulation of heat, temperature rising device will enter self-shield state, and complete machine cannot be worked.So the processing for heat is most important.Traditional radiating mode has fan cooling, fin conductive etc.Be not to have adopted certain suitable radiating mode just can guarantee that the heat dissipation problem of system is resolved, guarantee that radiating circuit is normal, reasonably work is also indispensable condition.
Summary of the invention
Technical assignment of the present invention is to provide a kind of computer intelligence control method for fan.
Technical assignment of the present invention is realized in the following manner, and this control method is realized by intelligent fan, control chip, temperature and rotating speed detection control module, alarm circuit, power supply;
This control method step is as follows:
First equipment is carried out to initialization, MCU now gives tacit consent to and does not report to the police, and control chip sends pwm signal to fan; Intelligent fan is adjusted the rotating speed of self according to pwm signal, control chip detects the FG signal that intelligent fan returns, and obtains the rotating speed when forefan; Control chip detects current temperature value simultaneously, and FG signal and temperature signal are sent to MCU end; MCU, by C.T. and rotating speed, judges that whether current intelligent fan duty is reasonable, and makes alignment processing.
Described MCU is by C.T. and rotating speed, judge that but the too low rotating speed of current intelligent fan temperature is too high or fan is undesired because of supply voltage unstable operation, now MCU will make the prompting of warning, by alarm circuit alarm, take current temperature value as standard simultaneously, reset pwm signal, by IIC, data are sent to control chip, reasonably control the rotating speed of fan.
Described MCU is by C.T. and rotating speed, judges that the temperature of current intelligent fan and tachometer value are in rational interval, and prompting custom system is working properly.
Described control chip is uploaded to MCU by FG signal and the temperature signal detecting by SMBUS bus.
Compared to the prior art a kind of computer intelligence control method for fan of the present invention, has the features such as reasonable in design, easy to use, has not only effectively solved the heat dissipation problem of system, and can guarantee that radiating circuit normally, reasonably work.
