Description
Technical field
The present invention relates to the technical fields such as desktop computer, domestic processor, embedded, FPGA, a kind of desktop computer Based Intelligent Control based on Domestic Platform and management method.
Background technology
Along with the universal of computer and extensively application, routine work or life are all difficult to divorced from computer, the heat radiation good in order to ensure computer and the performance of complete machine and stability, in complete machine, crucial radiating element is furnished with special heat radiation module and fan more, on common desktop computer, maximum (top) speed work generally pressed by fan, does not possess automatic control function, not only improves Overall Power Consumption under some application circumstances, also improve the noise of complete machine, use impression to bring harmful effect user.Additionally, ordinary desktop formula computer user can only carry out open and close machine control before equipment, it is impossible to realize long-range open and close machine and control.
Fast development along with domestic process, computer equipment based on domestic processor platform has obtained Rapid Popularization and application, it it is especially the demand meeting some application circumstances or application places, desktop computer is as equipment necessary to routine office work, the market demand and application prospect are the most wide, and in order to ensure stability and the reliable radiating effect of complete machine, the fan being equipped with in cabinet all works by maximum speed, this not only can increase Overall Power Consumption, also can improve noise.
Many outfit CPLD logic controllers on computer equipment, electrifying timing sequence and some particular interfaces to system operate or control, and can make full use of the resource of CPLD, gather the temperature information of mainboard key position and carry out the control of rotation speed of the fan；Can be operated by the control that CPLD reception, process serial data information execution are relevant simultaneously.
Summary of the invention
In order to solve above technical problem, the present invention proposes a kind of desktop computer Based Intelligent Control and management method.
The present invention considers intellectuality and the motility of switch machine machine control of Domestic Platform desktop computer fan control, especially under application circumstances or application scenario, it is proposed that a kind of desktop computer Based Intelligent Control based on Domestic Platform and management method.
Master control chip shares the CPLD logic control chip on mainboard, carries MAX6639PWM control chip and LM75A temperature sensor；CPLD on mainboard draws two-way I2C, is connected respectively on LM75A and MAX6639, for the transmission of data acquisition and control information；By CPLD simulative serial port signal, reception processes outside serial ports and sends the control information of coming.
CPLD is by the temperature sensor information on the I2C signal-obtaining mainboard of simulation, it is judged that configures depositor corresponding to MAX6639 after process, adjusts the PWM output waveform of MAX6639, it is achieved automatically control rotation speed of the fan；It addition, CPLD can monitor and read the control command sended over controlling serial ports, according to given protocol resolve command bag, then equipment is booted up, shut down or resets operation control by the GPIO interface of correspondence.
The invention has the beneficial effects as follows.
1) Master control chip of the method shares the CPLD logic control chip on mainboard, decreases the complexity of circuit design；
2) automatically controlling of the temperature sensing machine fan of key position in complete machine is realized；
3) the serial ports open and close machine reset operation realizing desktop computer controls, and meets the special requirement of user or some integrated application systems.
Accompanying drawing explanation
Fig. 1 is the basic hardware composition structural representation of the present invention.
Fig. 2 is the control Program Elementary Stream journey figure of the present invention.
Detailed description of the invention
Below present disclosure is carried out more detailed elaboration:
According to Fig. 1, the hardware that this invention relates generally to includes CPLD logic control element, LM75 temperature sensor, MAX6639PWM control chip and forms outer control serial ports.
CPLD logic control element on master controller multiplexing mainboard, on mainboard, crucial heat radiation position sets LM75 temperature sensor, and provides MX6639 dedicated fan control chip, and by CPLD simulative serial port signal, reception processes outside serial ports and sends the control information of coming.
CPLD on mainboard is communicated by GPIO interface simulation I2C, reads the temperature information of LM75 temperature sensor, according to the depositor of the temperature value configuration MAX6639 read, adjusts the PWM output waveform of MAX6639 and then realizes the control of rotation speed of the fan；CPLD monitor and read order bag will be resolved after controlling the control command that sends over of serial ports and with given protocol multilevel iudge, then by corresponding GPIO simulation open and close machine or reseting controling signal, it is achieved boot up equipment, shut down or reset operation control.
