Abstract

A power-saving method for the peripheral device with active scan includes such steps as adding an active scanner to the original peripheral device, scanning the peripheral device by said active scanner, checking if it is moved or pressed, generating the signal relative to its action, transmitting it, stopping the scanning, and waking up the peripheral device when it is moved or pressed.

Description

Power saving method for active scanning peripheral devices

The invention relates to an active scanning peripheral device power saving method, in particular to an active scanning peripheral device power saving method in which an active scanner is set in the peripheral device to perform timing scanning on the peripheral device.

Such as Taiwan Patent Publication No. 269022 "Mouse power-saving method and device for button detection", it mainly adds the action of timing the mouse to automatically turn off the power supply of the luminous body in the mouse after a period of time when the mouse does not move for a period of time in the original mouse circuit, and detects It detects whether the button on the mouse is pressed, as long as the button is pressed, the power supply of the illuminant is restored, so as to achieve the method of saving electricity and energy. It has many disadvantages as follows. For example, whether the mouse is pressed does not include whether it is moved. In fact, whether it is moved is more difficult than whether it is pressed, and it is more common and practical. This needs to be improved.

The main purpose of the present invention is to provide an active scanning peripheral device power saving method, which mainly sets an active scanner in the peripheral device to perform timing scanning on the peripheral device, and actively requires the use of data transmission. If the peripheral device is not being moved or pressed, the active scanner will temporarily stop timing scanning and keep sleeping during the non-scanning period. When the peripheral device is moved or pressed during the non-scanning period, it will immediately request data Transmission, the power supply of the illuminant in the peripheral device immediately resumes operation, and the peripheral device is not moved or pressed during the non-scanning period, then after the active scanner actively wakes up, it will start timing scanning and actively request the use of data Transmission, so it is very power-saving, and can prolong the sleep period without scanning at the same time, and can achieve generalization, practicality and environmental protection.

The purpose of the present invention is achieved in this way: a method for actively scanning peripheral devices to save power, mainly adding an active scanner to the original peripheral device circuit, which will automatically shut down after the peripheral device does not move and is not pressed for a period of time The action of the power supply of the illuminant in the peripheral device is then scanned by the active scanner to detect whether it is being moved or pressed; if so, the peripheral device can generate a signal corresponding to its action and If not, it means that the peripheral device is not in the state of being moved or pressed, the active scanner will temporarily stop timing scanning after the timing scanning time has passed, and keep sleeping during the non-scanning period. When the peripheral device is moved or pressed during the period, data transmission is required immediately, and the light source power supply in the peripheral device is activated immediately. During the non-scanning period, the peripheral device is not moved or pressed, and the active scanner wakes up After that, the timing scan is started again, actively requesting the use of data transmission.

Sleep states for active scanners include inactive, idle mode, and low-speed operation.

A scanning indicator light and a sleep indicator light can be set on the peripheral device to respectively display the timing scanning period or sleep period of the active scanner.

The present invention has the following advantages:

1. Actively request the use of data transfer.

2. When the peripheral device is not in the state of being moved or pressed, the active scanner will temporarily stop timing and scanning, and maintain a sleep and power-saving state.

3. When the peripheral device is moved or pressed during the non-scanning period, data transmission is required immediately, and the power supply of the light in the peripheral device is activated immediately, so it is very power-saving.

4. The unscanned sleep period can be extended, so it saves more power.

5. Can achieve generalization, practicality, environmental protection and power saving.

The present invention will be further described in detail below in combination with the accompanying drawings and specific embodiments.

Fig. 1 is the existing action flowchart;

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

Referring to Fig. 2, the present invention is an active scanning peripheral device power saving method, which mainly adds an active scanner to the original peripheral device (including input/output device) circuit, and the peripheral device does not move and does not press a section when timing After time, the action of automatically closing the power supply of the illuminant in the peripheral device, and then timing scanning of the peripheral device through the active scanner, the active scanner can be set at least 20mSXn as its best timing scan time (wherein n can be equal to one of 1 to 255 integers), the active scanner is only allowed to detect whether the peripheral device is being moved or pressed during the timing scan time; if so, the peripheral device can generate a corresponding motion and transmit the signal; if not, it means that the peripheral device is moved or pressed when it is not in the state, and the active scanner will temporarily stop timing scanning after the timing scanning time has passed, and keep the power-saving sleep state during the non-scanning period (including stop working, idle mode and power-saving sleep state of low-speed operation), it can be controlled by software to make it 1000 times the timing scan time. When the peripheral device is moved or pressed during the unscanning period, it will immediately request Data transmission, the power supply of the illuminant in the peripheral device will act immediately, and the peripheral device is not moved or pressed during the non-scanning period, and then the timing scan will start after the active scanner actively wakes up or returns to normal. It is required to press or move the peripheral device to facilitate the normal operation of the peripheral device. In the timing scan period and sleep period, a scan indicator light and a sleep indicator light can be respectively set on the peripheral device to save power. , The purpose of saving energy. Wherein, the active scanning peripheral device power saving method includes the following steps

1. Turn on the power supply 10;

2. Is the peripheral device used11? If yes, go to step 3, if not, go to step 4;

3. Normal peripheral device action 12, return to step 2;

4. Timing of unused time 13;

5. Is the timer timed out by 14? If not, go back to step 4, if yes, go to step 6;

6. Turn off the LED power supply:

7. Is the active scanner still in sleep16? If yes, go to step 11, if not, go to step 8;

8. Active scanner 17 after opening;

9. Timing scan 18;

10. Is the timing scan timeout 19? If yes, go to step 11, if not, go to step 12;

11. Pause scanning and sleep 20;

12. Is the peripheral device pressed or moved 21? If yes, go back to step 3, if not, go back to step 6.
