Description

201145007 VI. Description of the Invention: [Technical Field] The present invention relates to a power management method and a computer system using the same to save energy and power. [Prior Art] Nowadays, the flourishing development of Duhui computers has brought many conveniences to human life. Therefore, computers have become an indispensable tool for modern people's lives. For example, people can use data processing on computers to make work more important. It's quick and easy, you can also achieve audiovisual entertainment through your computer, and even get all kinds of information through your computer and the Internet. In addition, since environmental protection issues such as energy conservation and carbon reduction have been continuously raised, it is an important issue worthy of exploration and concern for the computer that is used in the long-term use of energy saving and power saving. According to the statement, most of the current computers have a time configuration program, which makes the computer have energy-saving and power-saving functions; please refer to the figure! It is a schematic diagram of the time configuration program provided in the conventional computer operating system. That is, the user can adjust the time parameter of the time configuration program t according to his own usage habits or the characteristics of the security, including the waiting time for turning off the monitor, waiting for the 201145007 hard disk to wait, and waiting for the system to stand by. Time α and 4 waiting time to enter the system sleep...Special time parameters, so that you can turn off the monitor or turn off the hard disk after the computer is idle for a period of time, or even enter the low-energy system standby state or 疋糸The system is dedicated to the purpose of energy saving. In addition, many computer operating systems have enabled the user to store the adjusted time parameters in a modular configuration in a modular manner; in other words, the user can set the adjusted time parameters to a single time. The parameter module is stored in the time configuration program, so the user only needs to select the option of the time parameter module instead of adjusting each individual time parameter separately. #然,, the user can also set another time parameter module to be stored in the time configuration program according to the usage type, so the user can select a suitable time parameter module according to the current situation of using the computer. However, the time configuration program provided in the conventional computer operating system has the following disadvantages due to the lack of humanization. · Many users want to prevent the computer from automatically turning off the monitor and turning off the hard disk just because the computer has not been operated for a while. Enter the system standby state or the system waiting state, so deliberately set the time parameter in the time configuration program to a longer waiting time, which will cause the computer to pass when the user leaves the seat and no longer uses the computer. The longer waiting time is set to start the power saving operation, so many power supplies in the long waiting time of this section have been wasted. In order to avoid the above situation, there is a conventional technique for using the sensor (4) to use the 201145007 whether the user is in the use position of the computer to determine whether the computer enters the power-saving system standby state, such as Taiwan's new patent No. 242777 or Chinese invention patent. According to the application of the publication No. 1286428, the patents are characterized in that when the user leaves the sensing range of the sensor, the computer directly switches to the system standby state, and when the user returns to the use position, the sensor enters the sensing range. At this time, the computer can immediately return to the normal use state within a predetermined time. However, if the user entering the sensing range does not want to use the computer, but only in the use position, the computer will still return to the normal use state, and can not maintain the effect of energy saving. Also, when users want to use a computer's newsletter (such as Microsoft PowerPoint) to report to a majority, they need to leave their seats frequently to facilitate reporting or commentary, or some computer users may need to work briefly. Temporarily leaving the seat, but do not want the computer to switch to the system standby state in the short time because the sensor does not detect the user is in the sensing range, which will cause the user to be troubled in the report.

Furthermore, 'the sensing proposed by the patent! ! It must be kept on at all times to achieve the desired function. However, the sensor that continues to consume power has limited power but has been in conflict with the original design of energy saving. 2. When a user uses a computer application to play multimedia audio files or watch streaming media via the Internet (5) coffee media, there is usually a long period of time without operating the computer, which will cause the user to watch multimedia. When the video file or the streaming media suddenly encounters the operation of the computer to start power saving, the display is turned off or 201145007 enters the system standby state. In order to avoid the above situation, many users will deliberately set the time parameter in the time configuration program to a longer waiting time, or turn off the power saving function, but when the user finishes watching the multimedia video file or streaming media, It is often not remembered to set the time parameter in the time configuration program to the original state, or to turn the power saving function back on. In view of the fact that many existing streaming media or multimedia audio and video playback software can automatically turn off part of the power saving function when the ® is executed, however, this will cause the playback software to be in a paused state and the user When you need to leave your seat for a while, the computer will continue to consume power. 3. When most users use a computer, the computer usually executes multiple work programs simultaneously in a multiplexed manner. 'Users often find it difficult to judge, or even lazy to select the appropriate time parameter module. 'So the computer is often not in The best power control mode 'will still waste a lot of power when used for a long time. ® As can be seen from the above description, the methods and time configuration programs used in energy saving and power saving in the conventional computer have significant defects and shortcomings and need to be improved.

In the first application embodiment, the present invention utilizes the sensor 22 to detect whether the user is located in the use position of the computer system 2 as a means for the computer system 2 to obtain the user's power saving operation situation. Please refer to FIG. 6' which is a block diagram of a method for the computer system to learn the user's power saving operation situation in the first application embodiment, and please refer to FIG. 2 in synchronization. Step P1: The sensor 22 is activated to detect whether the user is located in the use position of the computer system 2.

In this embodiment, the input device 23 is a π mouse, keyboard and optical lens module for the user to operate the computer system 2, and # Β ^ ^ ^ 22 is an infrared detector, and is placed on the computer. Input device 23; go to 鈇*田..., and do not limit the type and setting of the sensor 22 17 201145007 'If the sensor 223⁄4 is placed on the output device such as the screen or other peripherals of the computer system 2 The device is also available. Based on the above description, the power management method of the present invention can make the computer system 2 have the function of intelligent balance and energy saving; moreover, please refer to FIG. 7, which is a block flow chart of a better smart balance energy saving method. The first dotted line u is used to distinguish the state of the computer system 2, and the upper side of the broken line U represents the working state of the computer system 2 in normal use, and the lower side of the broken line U represents the state in which the computer system 2 is in a state of energy saving. Step A1: The computer system 2 is in the normal working state; Step A2: Turn off the sensor 22; 'The sudden control % member 27 selects the first energy parameter module 33, and the control element 27 selects the first energy parameter module. In the current group 33, the computer system 2 calculates the U waiting time set by the energy parameters Τ1~Τ5; wherein, in the embodiment, “the energy parameter of the parameter module 33 is set to be in the working state of the computer system (4)

Pre-Nam energy parameters Τι~Τ5 are used to adjust 4· for a longer time, the working frequency of the energy, and the occupants are pre-adjusted to a higher level. The original parameter F2 is pre-adjusted by the user, and is difficult to use. The source money is stored in the form of [Energy Recording 3^乍 in the computer system 2; the length of time T0 η跋I is flat to eight τ'- = 201145007 23 is stopped for operation _ length TG _ person step A5, if the time when the input device η stops operating has not reached the time length TG, the process proceeds to Μ; Step A5: Start sensor 22; Step A6: Xiang sense The detector 22 determines whether the (four) is located in the (four) system 2 use position 'where' if the sensor 22_ user is located in the use position of the computer system 2, then step A7, if the sensor 22_ user If it is not located in the use position of the computer system 2, the process proceeds to step A9; Step A7: The control element 27 still selects the first energy parameter module η to make the computer system 2 in the first power saving control mode and judge by the determining device η Whether the input device 23 is again operated during the time set by the first energy parameter module 33, and if the input device 23 is operated again within the time set by the first energy parameter touch 33, the operation returns to (4) A. Human device 23 in the first energy parameter module If the operation is not performed again within the set time of 33, the process proceeds to step μ; Step A8. In response to the energy parameters of the first energy parameter module 33, the computer system 2 adjusts the operation of the central processing unit in sequence. Frequency and operating voltage, start screen saver, turn off the monitor, turn off the hard drive, start the system standby, and enter system sleep, and return to step A6; Step A9: Control element 27 selects the second energy parameter module μ to enable The computer system 2 is in the second power-saving control mode, wherein if the computer system 2 has first entered the energy-saving state enabled in the first-power-saving control mode (such as starting the screen saver, turning off the monitor, turning off the hard disk, starting the system on standby) Or enter the line to sleep

19 201145007 The computer system 2 enters the second power-saving control mode while maintaining the enabled energy-saving state. For example, if the computer system 2 has entered the first-stage power-saving control mode before step A9 In the screen saver program, when the control component η then selects the first energy parameter module, the computer remains in the state of the enabled screen saver~ instead of recalculating the wait time for starting the screen saver (I), After a few minutes, enable the screen saver again. In one embodiment, the energy parameter of the first energy parameter module 34 is set to be used when the user is not in the use position of the computer system 2, that is, the user may not operate the computer for a short time. System 2, therefore, the energy parameters Τ1, Τ5' are pre-adjusted by the user to a shorter time, the energy parameter fi, which is pre-adjusted by the user to a lower operating frequency, and the energy parameter F2, which is pre-adjusted by the user The energy parameter is adjusted for the lower X and the adjusted energy parameter is stored in the computer system 2 in the form of the third energy parameter module 34. Step: use the sensor 2 2 to detect whether the user is located in the computer In the use position of the system 2, if the user of the system 22 is located at the use position of the computer line 2, the step AU is entered. If the sensor 22 detects that the user is not in the use position of the computer system 2, the process proceeds to step a. Step 12: The control component 27 selects the first energy parameter module 33 to make the computer system 2 in the first power saving control mode, and returns to step ^, wherein if the computer system 2 has advanced the second province The power-saving state of the dragon-controlled type (such as starting the screen saver, turning off the monitor, turning off the hard drive, starting the system standby or entering the system to sleep), the computer system 2 is kept in the enabled energy-saving state. On the premise, the first power-saving control mode is entered. For example, if the computer system 2 has entered the system enabled in the second power-saving control mode before the step a11, the control element 27 then selects the first energy source. When the parameter module is used, the computer system 2 remains in the standby state of the enabled system, instead of recalculating the waiting time for entering the system standby (after T3 minutes) and then entering the system for standby. Step A12: The control component 27 still selects to use the second energy parameter module % to enable the computer system 2 to be in the second power saving control mode, and uses the determining device 21 to determine whether the input device 23 is in the second energy parameter module 34. The set time is again operated, wherein if the input device 23 is operated again within the time set by the second energy parameter module 34, (4) step A if the input device 23 is in the second energy parameter module 34 If it is not operated again within the set time, proceed to step A. Step A13: In response to the energy parameter of the second energy parameter module, D1, D5, F1 and F2', the computer system 2 sequentially adjusts the operating frequency and the working voltage of the central processing unit, and activates the screen saver. Turn off the monitor, turn off the hard drive, start the system on standby, and enter system hibernation, and return to step A. According to the above description, the smart balance energy-saving method disclosed in the embodiment has the following advantages: 1. In response to different power-saving operation scenarios of the user, the control component 27 correspondingly selects the energy parameter module M of the appropriate S, In order to make the computer line 2 automatically in the appropriate power-saving control mode, the user no longer frequently uses the energy source parameter 21 201145007, or sets the energy parameter manually because he is lazy to manually adjust the energy parameter. For a longer waiting time, it is impossible to achieve energy saving. 2. Different from the prior art, the sensor 22 can directly switch to the standby state once the sensor 22 cannot detect the presence of the user, or directly return to the normal use state once the sensor 22 detects the presence of the user. On the contrary, the case is to flexibly provide a smart balance energy-saving function by using an appropriate energy parameter module to change the energy parameters in the energy parameter module, so that when the user needs to leave the seat from time to time, the computer is used. At 2 o'clock (such as when using the computer's briefing program to report to most people), the computer system 2 will not be switched to the system standby state immediately because the sensor 22 cannot detect the user, and the user will feel inward. The sensing range of the detector 22 is not to use the computer, 'the computer will not immediately return to the normal use state, so as to maintain the effect of energy saving. Furthermore, if the user is not in the sensing range of the sensor 22 and the computer is operated by other peripheral devices or remotely remotely, the judging device 21 judges that the computer system 2 is operated 'so the control element 27 corresponds The first energy parameter module 33 is selected to automatically operate the computer in a normal working state. 3. After the input device 2 3 is stopped for operation - after the length of time, the sensor 2 2 is activated 'and the sensor U will be turned off until the input device 23 is operated again 'so the sensor 22 will not be _ acre of p will be directly open, in order to save power consumption. In addition, in the present embodiment, the electric traceback and the shovel method can also be used in the office environment 22 201145007 to bring the following effects.
