Abstract
The present invention be more particularly directed to a kind of SCM Based remote on-off method.This SCM Based remote on-off method, including host computer, single-chip microcomputer, mainboard and power supply, described host computer is connected to mainboard and power supply by single-chip microcomputer, being communicated with single-chip microcomputer by host computer serial ports, single-chip microcomputer exports corresponding control signal according to the instruction that host computer provides, and then controls mainboard and power supply；Described host computer is connected to single-chip microcomputer by serial driver, and the RS232 rs 232 serial interface signal that described host computer sends accesses single-chip microcomputer after serial driver carries out level conversion.This SCM Based remote on-off method, is developed a kind of brand-new remote on-off method, is communicated with single-chip microcomputer by host computer serial ports, and then controls mainboard and on and off switch machine；Both be avoided that conventional BMC power on-off modes caused the wasting of resources, the problem bringing high cost, can reduce again design difficulty, more convenient to use flexibly, suitable popularization and application.
Description
Technical field
The present invention relates to monolithic computer remote control technical field, particularly to a kind of SCM Based remote on-off side
Method.
Background technology
Along with development and the application of electronic computer, convenient, flexible, on/off circuit the answering at electronic equipment of low-power consumption
It is particularly important in.Traditional switch machine mode necessarily requires user to contact with electronic equipment, use of could starting shooting, Jin Eryu
PERCOM peripheral communication.
Remote opening (Wake on Lan is called for short WOL), can be referred to as again remote wake up technology, refer to pass through office
Territory net, the Internet or communication network realize remote opening, no matter are accessed for that computer is how far from user, be in what position
Put, as long as by LAN, the Internet or communication network, just can be started at any time.
At present, the remote on-off mode of main flow uses BMC to be controlled, and this kind of mode is used in server product mostly
In, and complex circuit designs, relatively costly.
In the products such as desktop desktop computer, notebook, in BMC, many functions are frequently not and must use, and use this kind of side
Formula remote control switch machine causes the wasting of resources undoubtedly, and cost increases.
For the problems referred to above, the present invention devises a kind of SCM Based remote on-off method.It is intended to exploitation one
Both can avoid the high cost that the wasting of resources brings, design difficulty can have been reduced again, more convenient to use the most long-range
Method for start-up and shutdown.
Summary of the invention
The present invention is in order to make up the defect of prior art, it is provided that a kind of simple efficient SCM Based remote switch
Machine method.
The present invention is achieved through the following technical solutions:
A kind of SCM Based remote on-off method, it is characterised in that: include host computer, single-chip microcomputer, mainboard and power supply, institute
State host computer and be connected to mainboard and power supply by single-chip microcomputer, communicated with single-chip microcomputer by host computer serial ports, single-chip microcomputer according to
The instruction that host computer provides exports corresponding control signal, and then controls mainboard and power supply；Described host computer passes through serial port drive
Device is connected to single-chip microcomputer, and the RS232 rs 232 serial interface signal that described host computer sends accesses single after serial driver carries out level conversion
Sheet machine.
Described single-chip microcomputer uses MCS-51 single-chip microcomputer, and described serial driver uses MAX3243IDB serial driver.
The control signal that described host computer sends includes that mainboard open and close machine signal, mainboard reset signal and power supply enable letter
Number, described mainboard open and close machine signal and mainboard reset signal access mainboard by single-chip microcomputer, and described power supply enables signal by single
Sheet machine accesses power supply.
The invention has the beneficial effects as follows: this SCM Based remote on-off method, develop a kind of brand-new long-range
Method for start-up and shutdown, is communicated with single-chip microcomputer by host computer serial ports, and the instruction output that single-chip microcomputer provides according to host computer is corresponding
Control signal, and then control mainboard and on and off switch machine；Both it had been avoided that conventional BMC power on-off modes caused the wasting of resources, band
The problem carrying out high cost, can reduce again design difficulty, more convenient to use flexibly, suitable popularization and application.
Accompanying drawing explanation
Accompanying drawing 1 is the present invention SCM Based remote on-off method schematic diagram.
Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearer, below tie
Closing drawings and Examples, the present invention will be described in detail.It should be noted that, specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention.
This SCM Based remote on-off method, by serial port level conversion part, singlechip control part and periphery
Circuit forms, and above three parts is individually integrated on one piece of small-sized PCB.Serial port level conversion part includes host computer and serial ports
Driver, singlechip control part includes single-chip microcomputer, mainboard and power supply.Described serial port level conversion part and Single-chip Controlling portion
Divide and be attached by peripheral circuit.Described host computer is connected to mainboard and power supply by single-chip microcomputer, by host computer serial ports with
Single-chip microcomputer communicates, and single-chip microcomputer exports corresponding control signal according to the instruction that host computer provides, and then controls mainboard and electricity
Source.
The rs 232 serial interface signal level voltage amplitude sent from host computer due to the TTL signal level of single-chip microcomputer is different, host computer
The RS232 rs 232 serial interface signal sent can not directly use when receiving single-chip microcomputer, need to carry out level conversion through serial driver.Cause
This, described host computer is connected to single-chip microcomputer by serial driver, and the RS232 rs 232 serial interface signal that described host computer sends drives through serial ports
Dynamic device accesses single-chip microcomputer after carrying out level conversion.
Described single-chip microcomputer uses MCS-51 single-chip microcomputer, has a special interface for full duplex serial inside MCS-51 single-chip microcomputer
Mouth is connected with TTL rs 232 serial interface signal, controls mouth and can take over meaning I/O port.
