Abstract

One active scanner is added to peripheral line to time and scan peripherals and to check whether a peripheral is being moved or depressed or not. If so, the peripheral can produce corresponding signal and transmit it; if not, the active scanner stops its timing and scanning temporarily. During the no scanning period, if the peripheral is moved or depressed, it will demand data transmission at once; if the peripheral is not moved or depressed, it will be timed, scanned and demanded to transmit data again after the active scanner wakes up. This results in saving in power.

Description

The peripheral device electricity saving method of active scan

The present invention relates to a kind of peripheral device electricity saving method of active scan, refer to a kind of active scan device of in peripheral device, establishing especially, this peripheral device is implemented the peripheral device electricity saving method of the active scan of timing scanning.

Number as the Taiwan patent gazette the 269022nd " button detecting mouse electricity saving method and device ", it mainly adds the mouse that clocks and is failure to actuate and closes the action of luminophor power supply in the mouse after a period of time automatically in former mouse circuit, and whether button is pressed on the detecting mouse, as long as one has the power supply supply that pushes button and then recover luminophor, use the method that reaches power saving, energy savings.It is as follows that it has many shortcomings, for example mouse whether be pressed do not comprise whether be moved in, in fact whether be moved than the difficulty that whether is pressed and do, also general practical, this haves much room for improvement.

Fundamental purpose of the present invention is to provide a kind of peripheral device electricity saving method of active scan; it mainly establishes an active scan device in this peripheral device; this peripheral device is implemented timing scanning; require on one's own initiative to use data to transmit; if this peripheral device is not in and is moved or down state; this active scan device just temporarily stops timing scanning; and in the period of not scanning maintenance sleep state; working as this peripheral device in this period of not scanning is moved or presses; require data to transmit at once; the luminophor power supply recovers action immediately in this peripheral device; not scanning this peripheral device of period in this is not moved or presses; after treating that then this active scan device is initiatively wakeeed up; the scanning that picks up counting again requires to use data to transmit, so very power saving on one's own initiative; simultaneously the sleep period that this does not scan can be elongated, and generalization can be reached; practicability and environmental protectionization.

The object of the present invention is achieved like this: a kind of peripheral device electricity saving method of active scan, mainly in former peripheral device circuit, add the active scan device, this peripheral device of its timing does not move and not according to after following a period of time, just close the action of luminophor power supply in this peripheral device automatically, scan this peripheral device by this active scan device timing again, detect during whether it just be moved or pressing; If, just this peripheral device can produce with respect to the signal of its action and transfer out; If not, representing that this peripheral device is not in is moved or down state, this active scan device just temporarily stops timing scanning sweep time later in this timing, and in the period of not scanning maintenance sleep state, be moved or press in this this peripheral device of period of not scanning, require data to transmit at once, the luminophor power supply is moved immediately in this peripheral device, be not moved or press in this this peripheral device of period of not scanning, after treating that then this active scan device is wakeeed up, the scanning that picks up counting again requires to use data to transmit on one's own initiative.

The sleep state of active scan device comprise quit work, idle mode and low-speed handing.

Can establish a scanning pilot lamp and the sleep pilot lamp of a scanning period of timing when showing this active scan device place respectively or sleep period on the peripheral device.

The present invention has following advantage:

1, requires on one's own initiative to use data to transmit.

2, become silted up and be moved or down state in the peripheral device place, and the active scan device just temporarily stops timing scanning, and keep the sleep power down mode.

3, this peripheral device of period in not scanning is moved or presses, and requires data to transmit at once, and the luminophor power supply is moved immediately in this peripheral device, so very power saving.

4, can elongate the sleep period that this does not scan, so power saving more.

5, can reach generalization, practicability, environmental protectionization and province's electrification.

Below in conjunction with the present invention is described in further detail with accompanying drawing and specific embodiments.

Fig. 1 is existing action flow chart;

Fig. 2 is an action flow chart of the present invention.

Referring to Fig. 2, the present invention is a kind of peripheral device electricity saving method of active scan, it mainly adds the active scan device in former peripheral device (comprising input/output device) circuit, this peripheral device of its timing does not move and not according to after following a period of time, just close the action of luminophor power supply in this peripheral device automatically, scan this peripheral device by this active scan device timing again, this active scan device can be set minimum 20mSXn and be its best timing sweep time (wherein n can equal 1 to 255 integer one of them), and this active scan device only is allowed to during whether this peripheral device of detecting just is being moved or is pressing in this timing sweep time; If, just this peripheral device can produce with respect to the signal of its action and transfer out; If not, represent to be moved or down state when this peripheral device is not just being located, this active scan device just temporarily stops timing scanning sweep time later in this timing, and the time period of not scanning keep the power saving sleep state (to comprise and quitting work, the power saving sleep state of idle mode and low-speed handing), it can software control makes it reach 1000 times of this timing sweep time, working as this peripheral device in this period of not scanning is moved or presses, require data to transmit at once, the luminophor power supply is moved immediately in this peripheral device, be not moved or press in this this peripheral device of period of not scanning, then treat this active scan device initiatively wake up or recover normal after, scanning again picks up counting, require on one's own initiative to use and press or move this peripheral device, in order to normal peripheral device action, wherein in this timing scanning period and the sleep period can be established the one scan pilot lamp respectively and a sleep pilot lamp is shown on this peripheral device, use to reach power saving, the purpose of energy savings.Wherein, the peripheral device electricity saving method of this active scan comprises the following steps

1, opens back power supply 10;

Is 2, peripheral device used 11? if, enter step 3, if not, skip to step 4;

3, step 2 is got back in normal peripheral device action 12;

4, the timing unused time 13;

5, whether timing overtime 14? if not, get back to step 4, if enter step 6;

6, close LED power source:

7, whether the active scan device still in the sleep 16? if, enter step 11, if not, enter step 8;

8, drive back active scan device 17;

9, timing scanning 18;

Does 10, whether timing scan overtime 19? if, enter step 11, if not, skip to step 12;

11, suspend scanning and sleep 20;

Does is 12, peripheral device pressed or move 21? if, get back to step 3, if not, get back to step 6.
