用于可携式电子装置的操作模式控制方法及相关装置 A method for controlling an operation mode of the portable electronic device and related devices

技术领域 FIELD

[0001 ] 本发明有关一种用于可携式电子装置的操作模式控制方法及相关装置,尤指一种借助重力加速度传感器判断可携式电子装置的上盖是否开启并据以切换操作模式的控制方法及相关装置。 [0001] The present invention relates to an operating mode of portable electronic device and associated method for controlling the apparatus, particularly to a cover by means of the accelerometer is determined whether the portable electronic device is turned on and accordingly switching the operation mode The control method and related apparatus.

背景技术 Background technique

[0002] 笔记本电脑有着体积小、重量轻、携带方便等特性,能够让使用者轻易地在办公室以外的地方进行工作,并使用电脑系统的各种功能,而不必再被笨重的台式电脑限制在桌面之前。 [0002] laptop has a small size, light weight, easy to carry and other features to allow users to easily work in a place outside of the office, and use the various functions of a computer system, without having to be limited to bulky desktop computer Desktop before. 笔记本电脑的方便性及可携性能让使用者随时随地都能拥有强大的计算能力与文书处理功能,并提供完整的影音多媒体功能。 Convenience and portability of a laptop performance allows users to have anytime, anywhere computing power and word processing functions, and provides a complete audio and video multimedia capabilities.

[0003] 请参考图1,图1为现有的一笔记本电脑系统10的示意图。 [0003] Please refer to FIG 1, FIG. 1 is a schematic diagram of a conventional notebook computer system 10. 一般而言,笔记本电脑系统10是由一上盖100及一底座102所组成,上盖100与底座102是由一转轴104相连结。 Generally, a notebook computer system 10 is composed of a top cover 100 and a base 102 composed of the upper cover 100 and base 102 are coupled by a shaft 104. 上盖100可包含屏幕、照相机等,而底座102则包含键盘、触控板、电源开关、主机、扩充接口等。 Cover 100 may include a screen, a camera, etc., while the base 102 includes a keyboard, a touch panel, the power switch, the host, the expansion interface. 当要使用笔记本电脑系统10时,使用者需将主机的电源打开,调整上盖100中的屏幕显示角度至某一特定角度。 When using a laptop to system 10, the user needs to open the main power source, the upper cover 100 to adjust the angle of the display screen to a specific angle. 为了节省电源,笔记本电脑系统10中设有一切换开关,用来根据上盖100开启的角度,切换屏幕的启闭、主机的操作模式等。 To save power, the notebook computer system is provided with a switch 10, according to the angle of the upper cover 100 open, the opening and closing switch the screen, the operation mode of the host or the like. 例如,当使用者开启笔记本电脑系统10后而不需使用笔记本电脑系统10时,使用者可合上上盖100,使得上盖100与底座102间的角度小于一特定值,则笔记本电脑系统10会关闭屏幕,并操作于休眠模式。 For example, when a user opens the system 10 without the laptop computer system 10 using a laptop, the user can close the cover 100, such that the angle between the cover 100 and the base 102 is smaller than a certain value, the notebook computer system 10 It will close the screen, and operates in sleep mode.

[0004] 通过调整上盖100与底座102间的角度,使用者可节省电源消耗,并适时切换笔记本电脑系统10的操作模式。 [0004] By adjusting the angle between the upper cover 100 and the base 102, the user can save the power consumption, and, switching between a laptop mode of operation of the system 10. 因此,准确地检测上盖100与底座102间的角度就显得非常重要。 Accordingly, to accurately detect the angle between the cover 100 and the base 102 is very important. 在现有的技术中,检测上盖100开启角度的方法有许多种,其中之一是通过连结于转轴104的一机械式开关,亦即当转轴104的旋转角度小于一特定值时,即关闭屏幕及执行其它相关运作(如操作于休眠模式)。 In the prior art, the method of detecting the angle of opening the upper lid 100 has many kinds, one of which is a mechanical switch coupled to the shaft 104 by, i.e. when the rotation angle of the spindle 104 is less than a certain value, i.e., closed screen and perform other related operations (such as operating in sleep mode). 然而,机械式开关的组装较困难,且随着使用时间增加,可能产生机械疲乏或故障的情形,而导致可靠性降低。 However, the mechanical switch assembly more difficult, and with increasing time, situations may arise a mechanical failure or fatigue, resulting in decreased reliability.

[0005] 另一种现有的方式是通过磁极检测方式,如使用霍尔传感器(Hall Sensor)或磁阻式传感器(Magnetic Reluctance Sensor),检测上盖100与底座102间的距离,以判断上盖100与底座102间的角度。 [0005] Another conventional way by a magnetic pole detection method, such as Hall sensors (Hall Sensor) sensor or a magnetoresistive (Magnetic Reluctance Sensor), the distance between the base 102 and the cover 100 is detected for the determination the angle between the lid 100 and base 102. 以霍尔传感器为例,霍尔传感器可感应磁极、磁力等,因此,只要在上盖100与底座102中,分别增加一个磁铁及一霍尔传感器,即可通过霍尔传感器检测磁铁的磁力,而判断出上盖100与底座102间的距离,进而估算上盖100与底座102间的角度。 In an example a Hall sensor, a Hall sensor may sense magnetic poles, the magnetic force and the like, so long as the upper cover 100 and the base 102, and a magnet is increased by a Hall sensor, the magnetic force can be detected by the Hall sensor magnet, and it is determined that the distance between the cover 100 and base 102 are estimated from the angle between the cover 100 and base 102. 然而,通过磁极检测方式,在设置磁铁及传感器时,必须考虑传感器的灵敏度并搭配磁铁的磁通量,以符合设计需求。 However, the magnetic pole detection method, when the magnet and the sensor is provided, and sensitivity of the sensor must be considered with the magnetic flux of the magnet, to meet the design requirements. 另外,若使用磁阻式传感器时,由于磁阻式传感器的灵敏度高,造成其线性范围低,使得设计上的困难度提高。 Further, if using magnetoresistive sensors, due to the high sensitivity of the magnetoresistive sensor, resulting in low linear range, so that the difficulty of improving the design.

[0023] 为了避免机械式开关及磁极检测方式的缺点,本发明是使用重力加速度传感器(Gravity Acceleration Sensor,简称G-sensor),取得对应于铅垂线的角度(即绝对角度),进而判断笔记本电脑的上盖是否开启。 [0023] To avoid the disadvantages of a mechanical switch and a magnetic pole detection method, the present invention is the use of the accelerometer (Gravity Acceleration Sensor, referred to as G-sensor), to obtain the angle (i.e., an absolute angle) corresponding to the plumb line, so as to determine notebook superstructure computer is turned on. 如本领域具通常知识者所知,在重力场强度大于IG (G表示海平面高度的重力场强度)的环境,重力加速度传感器可用于检测加速度;而在重力场强度小于IG的环境,重力加速度传感器可根据所在位置的绝对角度,产生不同大小的电压、电流等电气或电子信号,因而可用来检测角度,其所对应的角度与输出电压关系如图2所示。 As it is known in the art with ordinary skills in the gravitational field strength greater than IG (G represents gravitational field strength at sea level) environment, the accelerometer operable to detect acceleration; and the gravitational field strength is less than IG environment, gravitational acceleration absolute angle sensor according to the location, produce different in voltage, current, electric or electronic signal, and thus can be used to detect the angle, the angle of its corresponding output voltage relationship shown in Fig. 由图2可知,随着所在位置的绝对角度的不同,重力加速度传感器所输出的电压值亦随之改变。 Figure 2 shows, with different absolute angle position where the voltage value of the gravitational acceleration sensor output also changes. 本发明即是利用此特性,准确判断一可携式电子装置的上盖是否开启,并据以切换可携式电子装置的操作模式,请见以下说明。 I.e., the present invention is the use of this feature, a cover accurately determine whether the portable electronic device is turned on, and accordingly switch the operation mode of the portable electronic device, see below. 特别注意的是,以下是以笔记本电脑系统为例说明本发明的实施方式,凡具有上盖及底座的可携式电子装置,如个人数字助理、 智能型移动电话等,皆适用于本发明。 Special attention is paid, the following system is a notebook computer as an example embodiment of the present invention, where the portable electronic device having a cover and a base, such as personal digital assistants, smart mobile phones, etc., are suitable for use in the present invention. 此外,本发明所使用的重力加速度传感器所输出的信号可以是任何型式的电气或电子信号,如电压、电流等。 In addition, the accelerometer signal is used in the present invention may be output by any type of electrical or electronic signals, such as voltage and current.

[0024] 进一步解释铅垂线、水平线及地表的关系,请参考图11,水平线是指在地表某点上沿水平方向的虚拟直线,而铅垂线则指在该点上垂直于水平线的虚拟直线,本发明所称的“绝对角度”是指相对于铅垂线的角度,例如角度X表示绝对角度为-45度,而角度y表示绝对角度为75度。 [0024] further explanation of the relationship between the vertical lines, horizontal lines and the ground, refer to FIG. 11, the horizontal line is a virtual straight line at a point in the horizontal direction of the surface, and refers to a virtual vertical line at the point on the horizontal line perpendicular to straight line, the present invention is called "absolute angle" means an angle with respect to a vertical line, for example, the angle X represents an absolute angle of -45 degrees, while the angle y represents an absolute angle is 75 degrees. 以此类推,若一笔记本电脑的底座置于水平面上且上盖合盖时,则上盖的绝对角度约为-90度。 So, if a base of the laptop is placed on a horizontal plane and the cover lid closed, the upper cover of the absolute angle of about -90 degrees. 因此,通过检测上盖的绝对角度,可得知上盖是否开启。 Therefore, by detecting the absolute angle of the cover, the cover can be learned is turned on.

[0025] 请参考图3,图3为本发明实施例一笔记本电脑系统30的示意图。 [0025] Please refer to FIG. 3, FIG. 3 is a schematic diagram of a notebook computer system 30 of the embodiment of the present invention. 笔记本电脑系统30可适时切换操作模式,用以节省电源消耗,其包含有一上盖300、一底座302及一操作模式控制装置40。 Notebook computer system 30 may be timely switching the operation mode to save power consumption, which includes a top cover 300, a base 302 and an operation mode control unit 40. 上盖300包含屏幕、照相机等,而底座302则包含键盘、触控板、电源开关、主机、扩充接口等。 Cover 300 comprises a screen, a camera, etc., while the base 302 includes a keyboard, a touch panel, the power switch, the host, the expansion interface. 请继续参考图4,图4为操作模式控制装置40的功能方块图。 Please continue to refer to FIG. 4, FIG. 4 is a functional block diagram of the operation mode of the control device 40. 操作模式控制装置40耦接于笔记本电脑系统30的一主机404,其包含有一重力加速度传感器400及一控制单元402。 Operation mode control means 40 is coupled to a host laptop computer system 40430, which includes a gravitational acceleration sensor 400 and a control unit 402. 重力加速度传感器400设于笔记本电脑系统30的上盖300上,用来检测上盖300对应于铅垂线的角度,并将检测结果(如电压、电流等电气或电子信号)输出至控制单元402。 A gravitational acceleration sensor 400 is provided on the upper cover 300 of the notebook computer system 30, for detecting the angle corresponding to the vertical line of the upper cover 300, and the detection result (such as voltage, current, electric or electronic signal) to the control unit 402 . 控制单元402较佳地设于笔记本电脑系统30的一键盘控制器中,用以根据重力加速度传感器400所得的检测结果,控制笔记本电脑系统30的操作模式。 The control unit 402 is preferably disposed on a laptop keyboard controller system 30 to the detection result obtained in the accelerometer 400, the operation mode of the control system 30 of the laptop.

[0026] 因此,通过操作模式控制装置40,笔记本电脑系统30可借助重力加速度传感器400测得上盖300对应于铅垂线的角度,以判断上盖300是否开启。 [0026] Thus, by the operating mode control means 40, a notebook computer system 30 may be a vertical line by an angle corresponding to the gravitational acceleration measured by sensor 400 cover 300, the upper cover 300 to determine whether to open. 特别注意的是,利用重力加速度传感器400判断上盖300是否开启的方式不限于特定程序或步骤,本领域具通常知识者当可设计符合所需的判断流程。 Of particular note is the use of gravitational acceleration sensor 400 determines whether the opening cover 300 is not limited to the specific procedures or steps, the present art having ordinary knowledge can be designed to meet when the required determination process. 举例来说,请参考图5,图5为本发明实施例一操作模式控制流程50的示意图。 For example, referring to FIG 5, which illustrates a schematic diagram of an embodiment 50 of the present invention, the operation mode control flow embodiment. 操作模式控制流程50用于操作模式控制装置40中,用以控制笔记本电脑系统30的操作模式,其包含以下步骤: Operation mode control process 50 is utilized in the operation mode control means 40 for controlling the operation mode of the notebook computer system 30, comprising the steps of:

[0027] 步骤500:开始。 [0027] Step 500: Start.

[0028] 步骤502 :通过重力加速度传感器400检测上盖300相对于铅垂线的一角度A。 [0028] Step 502: the upper cover 300 by detecting a gravitational acceleration sensor 400 with respect to a vertical line of the angle A.

[0029] 步骤504 :由控制单元402比较角度A是否小于一合盖角度A_def。 [0029] Step 504: the control unit 402 by the angle A is smaller than a comparison closing lid angle A_def. 若是,进行步骤506 ;若否,则回到步骤502。 If so, step 506; if not, the process returns to step 502.

[0031] 步骤508 :将笔记本电脑系统30操作于省电模式。 [0031] Step 508: the operating system 30 to the notebook computer power saving mode.

[0032] 因此,通过操作模式控制流程50,当重力加速度传感器400所测得的角度A小于合盖角度A_def时,控制单元402可判断上盖300已合盖,进而将笔记本电脑系统30操作于省电模式。 [0032] Thus, by controlling the operation mode of the process 50, when the gravitational acceleration sensor 400 is measured by the angle A is smaller than the angle closing lid A_def, the control unit 402 may determine the upper lid cover 300 is closed, and then the notebook computer system 30 is operating in power-saving mode. 在此情形下,只需将重力加速度传感器400固定于上盖300上,则重力加速度传感器400可随着上盖300不同的开启角度,产生不同大小的电压、电流等电气或电子信号(如图2所示)。 In this case, only the gravitational acceleration sensor 400 is fixed to the upper cover 300, the accelerometer 400 may cover 300 with different opening angles, produce different in voltage, current, electric or electronic signal (FIG. FIG 2). 如此一来,不需担心机械疲乏或故障的情形,且重力加速度传感器400固定于上盖300的位置不需特别考虑,因而可降低设计上的困难度。 Thus, the case without fear of mechanical failure or fatigue, and the gravitational acceleration sensor 400 is fixed to the upper cap 300 positions without special consideration, thus reducing the degree of difficulty in design.

[0033] 借助操作模式控制流程50,操作模式控制装置40可准确判断上盖300的绝对角度,并据以控制笔记本电脑系统30的操作模式。 [0033] 50 by means of a control flow of the operation mode, the operation mode control unit 40 may accurately determine the absolute angle of the upper cap 300, and accordingly the operation mode of the control system of the laptop 30. 为避免使用者在使用笔记本电脑系统30的过程中,搬动或移动笔记本电脑系统30使得笔记本电脑系统30不是静止的水平面上不动, 而造成误判而进入省电模式,本发明另提供一控制方式。 To avoid the user during use of the laptop system 30, lift or move the laptop notebook computer system 30 so that system 30 is not stationary horizontal plane does not move, and the misjudgment enter the power saving mode, the present invention further provides a control method. 请参考图6,图6为本发明实施例一操作模式控制流程60的示意图。 Please refer to FIG. 6, FIG. 6 a schematic view of embodiment 60 according to a flow control mode of operation of the present invention. 操作模式控制流程60用于操作模式控制装置40中,用以控制笔记本电脑系统30的操作模式,其包含以下步骤: Operation mode control process 60 for operating the mode control means 40 for controlling the operation mode of the notebook computer system 30, comprising the steps of:

[0034] 步骤600:开始。 [0034] Step 600: Start.

[0035] 步骤602 :通过重力加速度传感器400检测上盖300相对于铅垂线的一角度Al。 [0035] Step 602: cover 300 at an angle Al with respect to a vertical line through the sensor 400 detects the acceleration of gravity.

[0036] 步骤604 :延迟时间t。 [0036] Step 604: the delay time t.

[0037] 步骤606 :通过重力加速度传感器400检测上盖300相对于铅垂线的一角度A2。 [0037] Step 606: cover 300 with respect to a vertical line angle A2 by the gravitational acceleration sensor 400 detects.

[0038] 步骤608 :由控制单元402比较角度Al与角度A2是否相等。 [0038] Step 608: A2 are equal to the angle of the control unit 402 comparing the angle Al. 若角度Al与角度A2 相等,进行步骤610;若角度Al与角度A2不相等,则回到步骤602。 If the angle is equal to angle A2 and Al, step 610; if the angle is not equal to angle A2 and Al, the process returns to step 602.

[0039] 步骤610 :由控制单元402比较角度A2是否小于一合盖角度A3。 [0039] Step 610: the control unit 402 by the comparator A2 is smaller than angle a closing lid angle A3. 若是,进行步骤612 ;若否,则回到步骤602。 If so, step 612; if not, then returns to step 602.

[0040] 步骤612 :判断上盖300已合盖。 [0040] Step 612: determining whether the upper lid 300 is closed cover.

[0041] 步骤614 :将笔记本电脑系统30操作于省电模式。 [0041] Step 614: the operating system 30 to the notebook computer power saving mode.

[0042] 因此,通过操作模式控制流程60,重力加速度传感器400先测得的角度Al,延迟时间t后,再测得的角度A2。 [0042] Thus, by the operating mode control process 60, 400 first angle Al measured by the accelerometer, the delay time t, then the measured angle A2. 接着,若角度Al与角度A2相等,则控制单元402比较角度Al是否小于合盖角度A3,并于角度Al小于合盖角度A3时,判断上盖300已合盖,进而将笔记本电脑系统30操作于省电模式。 Next, if the angle is equal to angle A2 and Al, the comparison unit 402 controls whether the angle is less than the closing lid angle A3 Al, and Al is smaller than the angle angle A3 closing lid when the lid is closed is determined upper cap 300, and thus the notebook computer 30 operates the system in power-saving mode. 简单来说,在操作模式控制流程60,角度A1、A2皆为重力加速度传感器400所测得的绝对角度(即相对于铅垂线的角度),而合盖角度A3则为系统预设的临限角度。 Briefly, the operation mode control process 60, the angle A1, A2 gravitational acceleration sensor 400 are all measured absolute angle (i.e. an angle with respect to a vertical line), the closing lid for the system preset angle A3 Pro limit angle. 亦即,当角度A2小于合盖角度A3时,表示上盖300已合盖;相反地,当角度A2大于合盖角度A3时,则表示上盖300已开启。 That is, when the angle A2 is less than angle A3 closing lid, the upper lid 300 is closed indicates a cover; the contrary, when the angle A2 is greater than angle A3 when closing lid, said upper lid 300 is turned on. 如此一来,可据以决定笔记本电脑系统30 的操作模式。 In this way, it can determine the mode of operation according to the notebook computer system 30.

[0043] 比较操作模式控制流程60与操作模式控制流程50可知,操作模式控制流程60是在时间t内,检测上盖角度两次。 [0043] Comparison of the operating mode control process 60 and process 50 can be seen the operating mode control, the operating mode control process 60 at time t, the angle detecting cover twice. 当两次角度相等时,可判断笔记本电脑系统30未被搬动或移动,才继续判断上盖300是否已达合盖角度A3。 When the two angles are equal, it can be determined laptops or mobile system 30 is not moving, it continues to determine whether the upper lid 300 closing lid has reached an angle A3. 相反的,若两次角度不相等,表示笔记本电脑系统30被搬动或移动,则不判断上盖300是否已达合盖角度A3。 Conversely, if the two angles are not equal, the system indicates the notebook 30 is moving or moved, is not reached is determined whether the upper lid 300 closing lid angle A3. 如此一来,通过操作模式控制流程60,操作模式控制装置40可准确判断上盖300的角度,并可避免搬动笔记本电脑系统30所造成的误判。 Thus, by the operating mode control process 60, the operating mode of the control device 40 can accurately determine the angle of the upper cover 300, and can avoid misjudgment caused by moving Notebook System 30.

7[0044] 操作模式控制流程60可避免搬动笔记本电脑系统30所造成的误判,但若使用者躺着或以仰望方式使用笔记本电脑系统30,例如图12所示的情形,造成上盖300相对于铅垂线的角度小于合盖角度,则操作模式控制流程60仍可能发生误判的问题。 7 [0044] The operating mode control process 60 can avoid moving notebook system 30 caused by the misjudgment, but if a user to look up or lying down manner using laptop system 30, for example, the case shown in FIG. 12, causing the upper cover 300 angle relative to the vertical line is smaller than the angle of closing the lid, the operation mode control process 60 is still the problem of false positives that may occur. 因此,本发明另提供一控制方式。 Accordingly, the present invention further provides a control. 请参考图7,图7为本发明实施例一操作模式控制流程70的示意图。 Please refer to FIG. 7, a schematic diagram of FIG. 7 embodiment a process 70 according to the present invention, the operating mode control. 操作模式控制流程70用于操作模式控制装置40中,用以控制笔记本电脑系统30的操作模式,其包含以下步骤: Operation mode control process 70 for operating the mode control means 40 for controlling the operation mode of the notebook computer system 30, comprising the steps of:

[0045] 步骤700:开始。 [0045] Step 700: Start.

[0046] 步骤702 :通过重力加速度传感器400检测上盖300相对于铅垂线的一初始角度Al。 [0046] Step 702: an upper cap 300 with respect to the initial angle Al by a vertical line sensor 400 detects the acceleration of gravity.

[0047] 步骤704 :通过重力加速度传感器400检测上盖300相对于铅垂线的一角度A2。 [0047] Step 704: cover 300 with respect to a vertical line angle A2 by the gravitational acceleration sensor 400 detects.

[0048] 步骤706:延迟时间t。 [0048] Step 706: the delay time t.

[0049] 步骤708 :通过重力加速度传感器400检测上盖300相对于铅垂线的一角度A3。 [0049] Step 708: cover 300 with respect to the vertical line at an angle A3 of gravitational acceleration detected by the sensor 400.

[0050] 步骤710 :由控制单元402比较角度A2与角度A3是否相等。 [0050] Step 710: A3 by the control unit 402 are equal to angle A2 and an angle comparison. 若角度A2与角度A3 相等,进行步骤712 ;若角度A2与角度A3不相等,则回到步骤704。 If the angle A2 and an angle A3 is equal to, step 712; if the angle A2 and an angle A3 are not equal, the process returns to step 704.

[0051] 步骤712 :计算初始角度Al与角度A2的一角度差D1。 [0051] Step 712: calculate the initial angle Al with an angle of the angular difference D1 A2.

[0052] 步骤714 :由控制单元402比较角度差Dl是否大于一合盖角度差D2。 [0052] Step 714: the angular difference between the comparison control unit 402 is greater than a closing lid Dl angle difference D2. 若是,进行步骤716 ;若否,则回到步骤704。 If so, step 716; if not, then returns to step 704.

[0053] 步骤716 :判断上盖300已合盖。 [0053] Step 716: determining whether the upper lid 300 is closed cover.

[0054] 步骤718 :将笔记本电脑系统30操作于省电模式。 [0054] Step 718: the operating system 30 to the notebook computer power saving mode.

[0055] 因此,通过操作模式控制流程70,重力加速度传感器400先测得的初始角度Al,再于时间t内,测得的角度A2、A3。 [0055] Thus, by the operating mode control process 70, a gravitational acceleration sensor 400 to the measured initial angle Al, and then at time t, the measured angle A2, A3. 接着,若角度A2与角度A3相等,则控制单元402比较初始角度Al与角度A2的角度差Dl是否大于合盖角度差D2,并于角度差Dl大于合盖角度差D2时,判断上盖300已合盖,进而将笔记本电脑系统30操作于省电模式。 Next, when the angle A2 and an angle A3 equal, comparing the initial angle 402 and the angle Al unit A2 controls whether the angle difference is greater than the closing lid Dl angle difference D2, and the angle difference between the angle difference between the closing lid Dl greater than D2, the cover 300 is determined the cover is closed, and then the notebook computer system 30 is operating in the power saving mode. 简单来说,在操作模式控制流程70,初始角度Al为重力加速度传感器400 —开始(如笔记本电脑系统30刚开机时,或刚启动操作模式控制装置40时)所测得的绝对角度,角度A2、A3则分别为重力加速度传感器400于不同时间(延迟时间t)所测得的绝对角度,角度差Dl为初始角度Al 与角度A2的角度差,而合盖角度差D2则为系统预设的临限角度差。 Briefly, the operation mode control process 70, the initial angle Al is the gravitational acceleration sensor 400 - (when the control means 40, such as a notebook computer system 30 is just machines, or just starting operation mode) starts measured absolute angle, the angle A2 , A3 respectively 400 (delay time t) is the gravitational acceleration sensor at a different time measured absolute angle, the angle difference between the angle difference Dl Al angle A2 is the initial angle, and the angle difference D2 closing lid preset for the system threshold angle difference. 亦即,当角度差Dl大于合盖角度差D2时,表示上盖300已合盖;相反地,当角度差Dl小于合盖角度差D2时,则表示上盖300已开启。 That is, when the angle difference is greater than Dl closing lid when the angular difference D2, showing the upper cover 300 is closed cover; the contrary, when the angle difference between the angle difference between the closing lid Dl less than D2, said upper lid 300 is turned on. 如此一来,可据以决定笔记本电脑系统30的操作模式。 In this way, it can determine the mode of operation according to the notebook computer system 30.

[0056] 比较操作模式控制流程70与操作模式控制流程60可知,操作模式控制流程70是先纪录初始角度Al,然后在时间t内,检测上盖角度两次。 [0056] Comparison of the operating mode control process 70 and process 60 can be seen the operating mode control, the operating mode control process 70 is to record the initial angle Al, then during the time t, the angle detecting cover twice. 当两次角度相等时,可判断笔记本电脑系统30未被搬动或移动,才继续判断上盖300是否已合盖。 When the two angles are equal, it can be determined 30 is not moving or mobile notebook computer system, it is determined whether to continue to cover the upper lid 300 is closed. 相反的,若两次角度不相等,表示笔记本电脑系统30被搬动或移动,则不判断上盖300是否已合盖。 Conversely, if the two angles are not equal, the system indicates the notebook 30 is moving or moved, whether or not the cover is closed the upper cover 300 is determined. 如此一来,通过操作模式控制流程70,操作模式控制装置40可准确判断上盖300的角度,并可避免搬动笔记本电脑系统30所造成的误判。 Thus, by the operating mode control process 70, the operating mode of the control device 40 can accurately determine the angle of the upper cap 300, and can avoid misjudgment laptop moving system 30 caused. 同时,若使用者一开始即以躺着或仰望方式使用笔记本电脑系统30,操作模式控制流程70仍可借助比较角度差Dl与合盖角度差D2,而判断上盖300是否以合盖。 Meanwhile, if the user starts a manner that is lying or look up the system 30 using a laptop computer, the operating mode control process 70 by comparing the angle difference is still with the closing lid angle difference Dl D2, and determines whether the cover 300 closing lid.

[0057] 在图3所示的笔记本电脑系统30中,操作模式控制装置40仅使用一重力加速度传感器,即可判断上盖300的开启角度。 [0057] In the notebook computer system shown in FIG. 30, the operation mode control unit 40 uses only a gravitational acceleration sensor 300 can determine the opening angle of the upper cover. 除此之外,为提升判断准确性本发明另可使用二个以上的重力加速度传感器,判断上盖的开启角度。 In addition, to further enhance the determination accuracy of the present invention may use more than two gravitational acceleration sensor, it determines the opening angle of the upper cover. 请参考图8,图8为本发明实施例一笔记本电脑系统80的示意图。 Please refer to FIG. 8, FIG. 8 a schematic view of embodiment 80 of the present invention, a notebook computer system embodiment. 笔记本电脑系统80可适时切换操作模式,用以节省电源消耗,其包含有一上盖800、一底座802及一操作模式控制装置90。 Notebook computer system 80 may be timely switching the operation mode to save power consumption, which includes a top cover 800, a base 802 and an operation mode control means 90. 上盖800包含屏幕、照相机等, 而底座802则包含键盘、触控板、电源开关、主机、扩充接口等。 Cover 800 comprises a screen, a camera, etc., while the base 802 includes a keyboard, a touch panel, the power switch, the host, the expansion interface. 请继续参考图9,图9为操作模式控制装置90的功能方块图。 Please refer to FIG. 9, FIG. 9 is a functional block diagram of the operation mode of the control device 90. 操作模式控制装置90耦接于笔记本电脑系统80的一主机906,其包含有一第一重力加速度传感器900、一第二重力加速度传感器902及一控制单元904。 Operation mode control means 90 is coupled to a host system 80 laptop 906, which includes a first gravitational acceleration sensor 900, a second G sensor 902 and a control unit 904. 第一重力加速度传感器900设于笔记本电脑系统80的上盖800上,用来检测上盖800对应于铅垂线的角度,并将检测结果(如电压、电流等电气或电子信号)输出至控制单元904 ;而第二重力加速度传感器902则设于笔记本电脑系统80的底座802上,用来检测底座802对应于铅垂线的角度,并将检测结果(如电压、电流等电气或电子信号)输出至控制单元904。 A first gravitational acceleration sensor 900 is provided on the upper cover 80 Notebook System 800, for detecting the angle of the upper cover 800 corresponding to the vertical line of the detection result (such as voltage, current, electric or electronic signal) to the control unit 904; and the second G sensor 902 is provided on the base 802 of the laptop computer system 80, the base 802 for detecting an angle corresponding to the plumb line, and the detection result (such as voltage, current, electric or electronic signal) outputted to the control unit 904. 控制单元904较佳地设于笔记本电脑系统80的一键盘控制器中,用来根据第一重力加速度传感器900及第二重力加速度传感器902所得的检测结果,控制笔记本电脑系统80的操作模式。 The control unit 904 is preferably provided in a keyboard controller of the notebook computer system 80, according to a first gravitational acceleration sensor 900 and the detection result obtained in the second G sensor 902, the operation mode of the control system 80 laptop.

[0058] 因此,通过操作模式控制装置90,笔记本电脑系统80可借助第一重力加速度传感器900测得上盖800对应于铅垂线的角度,并通过第二重力加速度传感器902测得底座802 对应于铅垂线的角度,进而判断上盖800是否开启。 [0058] Thus, by the operating mode control means 90, a notebook computer system 80 may by means of the first G sensor 900 measured by the angle of the upper cover 800 corresponding to the plumb line, and measured by a second base 802 corresponding to the accelerometer 902 angle to a vertical line, and then determines whether the cover 800 is turned on. 特别注意的是,利用第一重力加速度传感器900及第二重力加速度传感器902判断上盖800是否开启的方式不限于特定程序或步骤,本领域具通常知识者当可设计符合所需的判断流程。 Of particular note is the use of the first G sensor 900 and the second G sensor 902 determines whether the opening cover 800 is not limited to the specific procedures or steps, the present art having ordinary knowledge can be designed to meet when the required determination process. 举例来说,请参考图10,图10为本发明实施例一操作模式控制流程110的示意图。 For example, please refer to FIG. 10, FIG. 10 is a schematic diagram of embodiment 110 of the embodiment of a flow control mode of operation of the invention. 操作模式控制流程110用于操作模式控制装置90中,用以控制笔记本电脑系统80的操作模式,其包含以下步骤: Operation mode control flow 110 for operating the mode control means 90 for controlling the operating mode of the notebook computer system 80, comprising the steps of:

[0059] 步骤112:开始。 [0059] Step 112: Start.

[0060] 步骤114 :通过第一重力加速度传感器900检测上盖800相对于铅垂线的一角度G1。 [0060] Step 114: cover 800 at an angle with respect to a vertical line G1 by the first sensor 900 detects the acceleration of gravity.

[0061] 步骤116 :通过第二重力加速度传感器902检测底座802相对于铅垂线的一角度G2 [0061] Step 116: 902 by detecting a gravitational acceleration sensor base 802 a second angle with respect to a vertical line G2

[0062] 步骤118 :由控制单元904计算角度Gl与角度G2的角度差Dl。 [0062] Step 118: calculating the angle of the angle Gl and G2 of the control unit 904 by the angle difference Dl.

[0063] 步骤120 :由控制单元904比较角度差Dl是否大于一合盖角度差D2。 [0063] Step 120: comparing unit 904 by the control angle difference is greater than a closing lid Dl angle difference D2. 若是,进行步骤122 ;若否,则回到步骤114及116。 If so, step 122; if not, the process returns to step 114 and 116.

[0064] 步骤122 :判断上盖800已合盖。 [0064] Step 122: determining whether the upper lid 800 is closed cover.

[0065] 步骤124 :将笔记本电脑系统80操作于省电模式。 [0065] Step 124: the operating system 80 to the notebook computer power saving mode.

[0066] 因此,通过操作模式控制流程110,第一重力加速度传感器900及第二重力加速度传感器902分别测得的角度Gl、G2后,控制单元904计算角度Gl与角度G2的角度差D1。 [0066] Thus, by controlling the operation mode of the process 110, the first G sensor 900 and the second G sensor 902 are measured angle Gl, G2 later, the control unit 904 calculates the angle and the angle G2, Gl angle difference D1. 接着,控制单元904比较角度差Dl是否大于合盖角度差D2,并于角度差Dl大于合盖角度差D2时,判断上盖800已合盖,进而将笔记本电脑系统80操作于省电模式。 Next, the control unit 904 comparing the difference angle is greater than the closing lid angular difference Dl D2, and the angle difference between the angle difference between the closing lid Dl greater than D2, it is judged cover lid 800 is closed, and then the notebook computer system 80 is operating in the power saving mode. 简单来说,在操作模式控制流程110,角度Gl、G2分别为第一重力加速度传感器900及第二重力加速度传感器902所测得的绝对角度(即相对于铅垂线的角度),两者的差为角度差D1,而合盖角度差D2则为系统预设的临限角度差。 Briefly, the control flow in the operation mode 110, the angle Gl, G2 respectively, the first G sensor 900 and the second G sensor 902 measured absolute angle (i.e. an angle with respect to a vertical line), both difference angle difference D1, D2 and the closing lid for the system angular difference preset threshold angular difference. 亦即,当角度差Dl大于合盖角度差D2时,表示上盖800已合盖;相反地,当角度差Dl小于合盖角度差D2时,则表示上盖800已开启。 That is, when the angle difference is greater than Dl closing lid when the angular difference D2, showing the upper cover 800 is closed cover; the contrary, when the angle difference between the angle difference between the closing lid Dl less than D2, said upper lid 800 is turned on. 如此一来,可据以决定笔记本电脑系统80的操作模式。 In this way, it can determine the mode of operation according to the notebook computer system 80. [0067] 因此,借助操作模式控制流程70,即使使用者以躺着或仰望方式使用笔记本电脑系统80,或是在使用的过程中,搬动或移动笔记本电脑系统80,操作模式控制装置90仍可借助比较角度差Dl与合盖角度差D2,而判断上盖800是否以合盖。 [0067] Thus, by the operation mode control process 70, even if the user to look up or lying down manner using laptop system 80, or the use of the process, moving or mobile notebook computer system 80, the operation mode of the control device 90 is still comparing the angle difference may be by means of the closing lid angle difference Dl D2, and determines whether the cover 800 closing lid.

[0068] 综上所述,本发明是借助重力加速度传感器判断笔记本电脑系统的上盖是否开启,并据以切换操作模式,因而可避免机械疲乏或故障的问题,并可大幅降低设计上的困难度。 [0068] In summary, the present invention is determined by the accelerometer system laptop cover is turned, and accordingly switch the operation mode, thus avoiding the problem of mechanical failure or fatigue, and can significantly reduce design difficulties degree.
