Detailed Description
In order to more clearly illustrate the invention, the invention is further described below with reference to preferred embodiments and the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
As shown in fig. 2, an embodiment of the present invention provides a mouse pen, which includes a power module, an optical sensor module, and a control module, where the optical sensor module is configured to control whether the power module in the mouse pen supplies power to the control module in the mouse pen according to a condition of sensing reflected light: and if the optical sensor module can sense the reflected light, controlling a power supply module in the mouse pen to supply power to a control module in the mouse pen.
The mouse pen provided by the embodiment can automatically judge the use state, the mechanism that the optical sensor module can sense the reflected light only when the mouse pen is close to an object such as a desktop and cannot sense the reflected light when the mouse pen is far away from the desktop is utilized, whether the mouse pen is close to the desktop or not is judged through sensing the reflected light by the optical sensor module, the use state is judged when the mouse pen is close to the desktop, the non-use state is judged when the mouse pen is far away from the desktop, and then the power supply to the control module is automatically stopped when the mouse pen is judged not to be used, so that the effective energy saving is realized.
In some optional implementation manners of this embodiment, the mouse pen includes a low dropout regulator connected between a power supply output end of the power supply module and a power supply input end of the control module, and the optical sensor module is configured to control the power supply module to supply power to the control module in the mouse pen by outputting an enable signal to the low dropout regulator.
The realization mode can effectively realize the on and off of the optical sensor module for the power supply module to supply power to the control module in time.
In a specific example, as shown in fig. 2, in the mouse pen provided in this embodiment, the power module includes a battery and other devices, the optical sensor module includes a light source (e.g., an LED), an optical sensor, and a digital signal processor DSP, the light source and the optical sensor are disposed on the head of the pen-shaped housing, the LED is used for emitting light, the optical sensor is used for sensing reflected light of an object (e.g., a desktop), and the digital signal processor is used for determining a moving direction and a displacement of the mouse pen according to the reflected light sensed by the optical sensor, and transmitting the moving direction and the displacement to the control module through the serial peripheral interface SPI; the control module comprises a micro control unit MCU, a clock circuit, an antenna matching circuit, an antenna and other devices, wherein the micro control unit is used for processing the moving direction and displacement of the mouse pen and then sending the processed movement direction and displacement to a host computer of the computer through the antenna. The voltage of the output end of the power supply module is divided into two parts, one part supplies power to the control module, and the other part supplies power to the optical sensor module. As shown in fig. 3, when the pen point of the mouse pen is in contact with or is close to the desktop (state 1 in fig. 3), for example, when the distance between the optical sensor and the desktop is less than or equal to 2mm, the optical sensor can sense the reflected light of the desktop for the light emitted by the LED, at this time, the digital signal processor outputs a high-level enable signal through the control pin of the state output module, and the power module supplies power to the control module by turning on the low dropout regulator LDO1 serving as a switch; and when the pen point of the mouse pen is not in contact with the desktop or is far away from the desktop (state 2 in fig. 3), for example, when the distance between the optical sensor and the desktop is greater than 2mm, the optical sensor cannot sense the reflected light of the desktop to the light emitted by the LED, at this time, the digital signal processor outputs a low-level enable signal through the control pin of the state output module, and the power module stops supplying power to the control module by turning off the low dropout linear regulator LDO1 serving as a switch, so that the devices such as the MCU in the control module are all turned off, and the mouse pen enters a low-power energy-saving mode. Because the electric energy loss of the mouse pen is mainly concentrated on the MCU in the control module and peripheral circuits thereof, the power supply of the control module is controlled to be turned off, and the energy consumption of the whole mouse pen can be effectively saved.
In some optional implementations of this embodiment, the controlling, by the optical sensor module, whether the power module in the mouse pen supplies power to the control module in the mouse pen according to the condition of sensing the reflected light includes:
the optical sensor module is used for controlling whether a power supply module in the mouse pen supplies power to a control module in the mouse pen according to the condition of sensing reflected light: and if the optical sensor module can sense the reflected light and detect that the mouse pen moves according to the sensed reflected light, controlling a power supply module in the mouse pen to supply power to a control module in the mouse pen.
This implementation, on the basis of judging whether mouse pen is close to the desktop, through whether there is the motion according to the reverberation detection mouse pen that senses, just judge the user state when being close to the desktop and having the motion, and keep away from the desktop and judge the more accurate effectual user state judgement mode of non-user state when being close to the desktop but not having the motion, can realize more effectual energy saving and consumption.
In some optional implementations of this embodiment, the controlling, by the optical sensor module, whether the power module in the mouse pen supplies power to the control module in the mouse pen according to the condition of sensing the reflected light includes:
the optical sensor module is used for controlling whether a power supply module in the mouse pen supplies power to a control module in the mouse pen according to the condition of sensing reflected light: and if the optical sensor module can sense the reflected light, detect that the mouse pen moves according to the sensed reflected light and judge that the movement is effective movement according to the movement track, controlling a power supply module in the mouse pen to supply power to a control module in the mouse pen.
According to the implementation mode, on the basis of judging whether the mouse pen is close to the desktop and whether the mouse pen moves, whether the mouse pen moves effectively or not is judged according to the motion track, the mouse pen is judged to be in a use state when the mouse pen moves effectively and moves close to the desktop, and a more accurate and effective use state judgment mode is judged to be in an unused state when the mouse pen moves irregularly and does not move although the mouse pen moves close to the desktop is realized, so that more effective energy saving can be realized.
In a specific example, as shown in fig. 4, in the case where the mouse pen is in contact with the desktop, if the mouse pen is not normally used, the user may draw a trajectory similar to the movement trajectories 3 and 5 of fig. 4, that is, a random trajectory within a small range. When the digital signal processor detects that the movement track of the mouse pen in unit time is irregular track in a small range similar to the movement tracks 3 and 5 in the figure 4, the mouse pen is judged not to be used; on the contrary, when the digital signal processor detects that the movement locus of the mouse pen in the unit time is similar to the movement loci 1, 2 and 4 in the figure 4, the mouse pen is judged to be used.
In some optional implementations of this embodiment, the determining, by the optical sensor module, that the motion is the effective motion according to the motion trajectory includes: the optical sensor module is used for dividing an area where a total motion track formed by all motion track line segments in a set time interval is located into a plurality of sub-areas, judging whether the number of the motion track line segments contained in each sub-area in the set time interval is smaller than a set threshold value respectively, and if so, judging that the motion is effective motion.
The implementation mode can accurately and effectively judge whether the movement of the mouse pen is effective movement or irregular movement, can ensure effective realization and save energy consumption, and can avoid misjudgment and close the mouse pen when a user normally uses the mouse pen.
In a specific example, when the mouse pen contacts with the desktop, the data signal processor may establish an x-y rectangular coordinate system in an analog manner, and set the x-y rectangular coordinate system at the initial time t0The position of the mouse pen is (x)0，y0) T after a time interval Δ t1The position of the mouse pen at the moment is (x)1，y1) Then the motion track of the 1 st motion track segment of the mouse pen at the time of delta t is the slave (x)0，y0) To (x)1，y1) The formula of the ith motion trail segment of the mouse pen is represented as route (t)i)＝line(xi-xi-1,yi-yi-1). Assuming that the set period is 10 Δ t, thenChanging the total number of 10 motion trajectory line segments in the set time period, wherein the total motion trajectory composed of the 10 motion trajectory line segments is as shown in fig. 5, equally dividing the region where the total motion trajectory is located into a plurality of sub-regions, determining whether the number of motion trajectory line segments included in each sub-region is less than a set threshold value, for example, 3, if so, determining that the motion in the set time period is an effective motion, otherwise, determining that the motion in the set time period is a random motion, and turning off the control module. It can be understood that the specific values of the setting time period, the specific size of the sub-region and the specific values of the setting threshold can be set according to the precision requirement and the habit of the user.
It will be appreciated that the structure and function of the mouse pen provided by the above embodiments can also be applied to a conventional wireless optical mouse. In addition, the mouse can also be applied to a wired optical mouse to save the energy consumption of a computer host.
