Description
Technical field
The utility model relates to a kind of computer power intelligent management system based on the ATX power supply.
Background technology
In the prior art, known technology is the development along with science and technology, and computer has been deep into social every field, and the Industry Control except routine office work, life ﹠ amusement, medicine equipment, instrument and equipment etc. also all be unable to do without computer everywhere.But the computer that uses now is except notebook, the overwhelming majority is not integrated UPS battery electric power system, the barrier propterty that does not have the unexpected power down of external power source, also can't break away from external power source works alone, the ability that does not more possess the information such as the battery operated state of intelligent display and dump energy under operating system brings a lot of inconvenience for numerous application scenario users.This is the existing weak point of prior art.
Summary of the invention
The purpose of this utility model, be exactly for the existing deficiency of prior art, and provide a kind of technical scheme of the computer power intelligent management system based on the ATX power supply, the system of this scheme be used for to lithium battery discharge and recharge control and relevant information management, realize the control output of ATX power supply; And have input protection function such as input over-voltage and over-current etc., external power source and lithium battery power supply can seamless automatic conversions; ATX power supply output with standard has the output protecting functions such as output overvoltage, under-voltage, overcurrent, short circuit.
This programme is achieved by the following technical measures: a kind of computer power intelligent management system based on the ATX power supply; include single-chip microcomputer; the characteristics of this programme are: described single-chip microcomputer is connected with the management of charging and discharging module with lithium battery respectively; described management of charging and discharging module is connected with lithium battery; power supply is connected with the management of charging and discharging module by the input protection module; have a power supply to select module to be connected with the input protection module with lithium battery respectively, described power supply protection module is connected with a power supply monitoring module by voltage transformation module.Described single-chip microcomputer passes through USB mouth or serial ports or Smbus bus interface and is connected with host computer.Described single-chip microcomputer is connected by the Smbus bus with lithium battery, management of charging and discharging module.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, single-chip microcomputer can send according to current lithium battery information and discharge and recharge instruction to the management of charging and discharging module; Power supply selects module which kind of mode of choice for use to power, and when power supply is arranged, then uses the power supply power supply, when not having power supply, just by lithium battery power supply; Voltage transformation module can be realized multiple voltage output, satisfies computer to the demand of various voltages; The power supply monitoring module can be monitored the voltage of output; Described single-chip microcomputer passes through USB mouth or serial ports or Smbus bus interface and is connected with host computer, battery information is uploaded to computer, in order to the information such as battery operated state and dump energy are shown under computer system.3 kinds of communication interfaces have really been realized plug and play with automatic identification function.This shows, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, 1 is single-chip microcomputer, and 2 is lithium battery, and 3 is the management of charging and discharging module, and 4 is power supply, and 5 are the input protection module, and 6 are power supply selection module, and 7 is voltage transformation module, and 8 is the power supply monitoring module, and 9 is communication interface module.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can find out by accompanying drawing; the computer power intelligent management system based on the ATX power supply of this programme; include single-chip microcomputer 1; described single-chip microcomputer 1 is connected with the management of charging and discharging module with lithium battery 2 respectively and is connected; described management of charging and discharging module 3 is connected with lithium battery 2; power supply 4 is connected with management of charging and discharging module 3 by input protection module 5; have a power supply to select module 6 to be connected with the input protection module with lithium battery 2 respectively and be connected, described power supply protection module 6 is connected with a power supply monitoring module 8 by voltage transformation module 7.Described single-chip microcomputer 1 also is connected with a communication interface module 9.Described single-chip microcomputer 1 is connected by the Smbus bus with lithium battery 2, management of charging and discharging module 3.
After power supply 4 is connected, pass through first input protection module 5, if the external input voltage input is excessive, input protection module 5 can be stopped power supply, and plays the over-voltage over-current protection function.When power supply 4 and lithium battery 2 existed simultaneously, power supply selected module 6 acquiescence to select power supplies 4 power supplies, otherwise, use lithium battery 2 power supplies.
During start, press the key of computer, have a signal and pass to single-chip microcomputer 1, single-chip microcomputer 1 control modules is started working, simultaneously, whether the voltage that power supply monitoring module 8 can be monitored each voltage transformation module 7 outputs is normal, and with corresponding information feedback to the computer mainboard, if voltage is normal, the computer normal boot-strap, otherwise computer can not normal boot-strap.During system closedown, power supply monitoring module 8 receives mainboard information, the output voltage of shutoff voltage modular converter 7, and simultaneously, single-chip microcomputer 1 receives mainboard information, automatically enters holding state, system closedown.In the situation that the normal boot-strap operation, detecting software can be to adopt any interface mode to carry out data communication by communication interface module 9 automatic identification computers and single-chip microcomputer 1, thereby gathers lithium battery 2 information.
