[0032] 本发明提供一种具有省电功能操作的嵌入式电子装置,在此所指省电功能操作的部分是指嵌入式电子装置在进入省电模式操作之后,可通过一种更为省电的方式来更新嵌入式电子装置所使用电池的电量状态,以达到在更新过程中能减少电池电量消耗的效果。 [0032] The present invention provides an embedded electronic device having a power saving function is operated, the power saving function as referred to herein refers to the operation portion is embedded in the electronic device after entering the power saving mode operation may be achieved by a more province electrically embedded electronic device to update the battery state of charge, in order to achieve the effect of the update process can reduce battery consumption.

[0033] 接下来请参阅图3,其为本发明优选实施例的嵌入式电子装置的功能方块图。 [0033] Next, please refer to FIG. 3, which present a functional block diagram of an embedded electronic device according to a preferred embodiment of the invention. 本实施例所述的嵌入式电子装置2指一种通过电池24取得电源供应的装置,例如可以为笔记本型电脑、个人数字助理、可携式导航设备……等,在此上述装置仅用于举例说明且仍可包括其他种类的电子装置。 The embedded electronic device of Example 2 of the present embodiment refers to a device by a battery power supply 24 made, for example, may be a notebook computer, a personal digital assistant, portable navigation devices ...... like, this is only for the above-described means illustrate and still include other types of electronic devices. 嵌入式电子装置2主要包括运算系统20及微处理器22。 2 includes an embedded electronic device 20 and microprocessor 22 computing system. 其中运算系统20为嵌入式电子装置2的运算核心,并根据不同种类的嵌入式电子装置2而相对提供所需的功能操作,并且此运算系统20至少提供有省电模式的功能操作,此省电模式在执行时仅保持嵌入式电子装置2必要的电源供应,如唤醒省电模式操作所需的相关电路部分的电源即予以保留供应,而其余电路部分则予以断电或仅以最小耗电模式供电。 Wherein the computing system 20 is embedded as the core operation of the electronic device 2, and the relative operation to provide the desired functionality depending on the type of the embedded electronic device 2, and this operation provides at least 20 functional operating system has the power saving mode, this provincial mode while performing the electrical holding power supply need only 2 embedded electronic device, such as a power-related portion of the wake-up circuitry required to operate the power saving mode, i.e. the supply to be retained, while the remaining part of the circuit to be powered down or only minimum consumption mode power supply.

[0034] 而至于微处理器22的部分则耦接于运算系统20与电池24之间,微处理器22主要是用来检测电池24的电量变化,并可在嵌入式电子装置2进入省电模式之后,以一种更为省电的方式来唤醒嵌入式电子装置2以进行电池24的电量更新。 [0034] As for the microprocessor portion 22 is coupled to the computing system 20 and the battery 24, microprocessor 22 is mainly used to charge the battery 24 detected a change, the electronic device can be embedded into the power 2 after the pattern, in a more energy-efficient way to wake up the embedded electronic device 2 to charge the battery 24 for updates. 鉴于传统更新电池电量的方式是每隔一段固定时间即对省电模式中的嵌入式电子装置2予以唤醒操作,但此种方式因执行过多的唤醒次数而导致了电池24电量的更快速消耗。 In view of the conventional approach is to update the battery at intervals of a fixed time, i.e. the power saving mode of the electronic device 2 to be embedded wake-up, but this way too many times due to the implementation of wake-up leading to charge the battery 24 more rapidly consumed . 因此本实施例的微处理器22仅有在电池24电量达到特定的电量时,才会对嵌入式电子装置2予以唤醒以进行电池24的电量更新。 Therefore, this embodiment of the microprocessor 22 only when the battery 24 reaches a certain amount of electricity, will wake up to be embedded in the electronic device 2 for charge of the battery 24 is updated.

[0035] 前述本实施例的运算系统20可视为中央处理器及操作系统的组合,并通过中央处理器提供的运算处理及操作系统的功能服务来完成嵌入式电子装置2所需的功能操作; 而微处理器22可通过单芯片微处理器来实施。 [0035] The computing system 20 of the present embodiment may be considered as a central processing unit and operating system combination, the arithmetic processing by the central processor and providing operating system functionality and services to achieve the desired functionality 2 embedded electronic device operates ; and the microprocessor 22 may be implemented by a single chip microprocessor. 然而在此对运算系统20及微处理器22的实施方式做说明仅是为了更进一步说明本发明的技术特点,并非用以限制本发明的范围, 凡本技术领域人员所想到的等同实施方式,均落在本发明的保护精神中。 However, in this embodiment of the computing system 20 and the microprocessor 22 to do further description it is only for describing the technical features of the present invention is not intended to limit the scope of the present invention, where the present embodiment equivalents that occur to those skilled, as fall protection spirit of the present invention.

[0036] 再参阅图3,微处理器22以持续性检测或间隔性检测来得知电池24目前的即时电量状态,并将此电池的即时电量状态与微处理器22内部所预设的至少一组警示电量做比较,且只在比对结果相等时,即电池24的即时电量等于警示电量时,微处理器22即会通知嵌入式电子装置2需从省电模式中唤醒且需更新电池24的电量状态。 [0036] Referring again to FIG. 3, the microprocessor 22 to continuously or intermittently detection 24 that detects the current instant to the state of charge of the battery, and the instant state of charge of the battery of this the microprocessor 22 with the interior of at least a predetermined when the battery warning group compared, and only when the comparison result is equal, i.e., the battery 24 is equal to power instant power warning, the microprocessor 22 will notify the embedded electronic device 2 needs to wake from the power saving mode and the battery 24 to be updated the state of charge.

[0037] 接下来更进一步说明嵌入式电子装置2如何被唤醒及更新电池24的电量状态,当微处理器22检测得知电池24电量等于警示电量时,微处理器22输出中断信号(Interrupt)及电池24目前电量的信息(Information)给运算系统20,使得运算系统20 可根据收到的中断信号而从省电模式中被唤醒,且根据收到电池目前电量的信息来更新电池24的电量状态。 [0037] Next, further explanation how the embedded electronic device 2 and is awakened state of battery 24 is updated, when the microprocessor 22 detects that the battery charge warning level is equal to 24, microprocessor 22 outputs an interrupt signal (Interrupt) battery 24 and the current charge information (information) to the computing system 20, so that the computing system 20 may be awakened from a power saving mode according to the received interrupt signal, and the charge of the battery 24 is updated based on the information received in the battery charge current status.

[0038] 接着请继续参阅图4,并同时配合参考图3,图4为本发明优选实施例的嵌入式电子装置的省电方法的流程图,执行步骤如下: [0038] Next, please refer to FIG. 4, a flowchart of a power saving method and an embedded electronic device with reference to FIG. 3, FIG. 4 of the present invention in conjunction with the preferred embodiment, perform the following steps:

[0039] 首先,使得嵌入式电子装置2进入省电模式的功能操作(如步骤S401),例如嵌入式电子装置2在一段时间不操作即自动进入省电模式亦或直接将嵌入式电子装置2的工作模式切换至省电模式; [0039] First, such embedded electronic device 2 enters power saving mode operating function (step S401), such as an embedded electronic device 2 does not operate in a period of time or will automatically enter a power saving mode of the electronic device 2 is directly embedded operation mode is switched to the power saving mode;

[0040] 接下来通过微处理器22来检测电池24以取得目前电池的即时电量(如步骤S403); [0040] Next, the battery 24 is detected by the microprocessor 22 to obtain the current real time battery power (step S403);

[0041 ] 之后根据步骤S403的检测结果,微处理器22判断电池24的即时电量是否等于警示电量(如步骤S405); After [0041] detection result of step S403, the microprocessor 22 determines whether the instant power of the battery 24 is equal to the charge warning (step S405);

[0042] 而当步骤S405判断为是时,则微处理器22输出中断信号给运算系统20 (如步骤S407); [0042] When it is determined in step S405, the microprocessor 22 outputs an interrupt signal to the computing system 20 (step S407);

[0043] 之后运算系统20根据收到的中断信号即可以从省电模式中被唤醒(如步骤S409),并通过微处理器22来取得电池24的即时电量; After [0043] The computing system 20 receives an interrupt signal which can be awakened from the power saving mode (step S409), and acquires an instant charge of the battery 24 by the microprocessor 22;

[0044] 然后,运算系统20即可以根据接收到电池24的即时电量而来更新电池24的状态,之后回到步骤S401以使得嵌入式电子装置2再度进入省电模式,且重复前述步骤的执行,直到嵌入式电子装置2通过人为操作方式脱离省电模式而回到正常运作模式为止。 [0044] Then, computing system 20 that is received depending on the state of the instant power of the battery 24 from the battery 24 is updated, then returns to step S401 so that the embedded electronic device 2 again enters the power saving mode, and repeating the foregoing steps performed , 2 until the embedded electronic device from the power saving mode and manual operation mode until the return to the normal operation mode.

[0045] 前述步骤S405当判断为否时,则回到步骤S403继续执行。 [0045] When it is determined in the previous step S405 is NO, the process returns to step S403 to continue.

[0046] 前述步骤S405中判断使用的警示电量预设于微处理器22中,且微处理器22可以预设多组不同的警示电量,以使得电池24在不同时间下的电量变化只要符合这些警示电量的其中之一,均可以被运算系统20得知且更新电池24的状态。 [0046] The foregoing step S405 is determined using a preset alert charge in the microprocessor 22, and microprocessor 22 may be preset different sets of warning amount, so that the power battery 24 changes at different times provided that they meet these one warning electricity, are known and can be updated state of the battery 20 of the computing system 24. 因此通过本实施例所述的方法可以确实将电池电量的变化通过更新而反应出来,且此更新过程中具有较佳的省电效果。 Indeed it is possible to change the battery reacted by the method described in the embodiment by updating it, and this update process has a better power-saving effect.

[0047] 接着请继续参阅图5,图5用来说明采用传统方法与采用本实施例的方法所更新电池的比较示意图。 [0047] Next, please continue to refer to FIG. 5, a schematic diagram of FIG. 5 and Comparative Example of the method of the present embodiment uses the updated cell for explaining a conventional method. 图5中的Vbat为电池24的电量,Control A为传统嵌入式电子装置(如图1所示)的工作控制信号,control B为本实施例的嵌入式电子装置的工作控制信号。 Operation control signal in FIG. 5 Vbat is the battery 24, Control A conventional embedded electronic device (FIG. 1), control B work embedded electronic device according to a control signal of the present embodiment. 而上述control A及control B在高电平状态时即代表嵌入式电子装置工作在正常运作下,而control A及control B在低电平状态时即代表嵌入式电子装置工作在省电模式下。 And said control A and control B at the high level state, that is representative of an embedded electronic device operates in the normal operation, the control A and control B at the low level state, that is representative of the embedded electronic device operates in the power saving mode. 从图5可以得知传统方法是每隔一段固定时间就将系统唤醒,以更新电池的状态, 如controlA的控制信号所示;而本实施例所述的新方法则只有在电池电量为3. 9V、3. 7V、 3. 6V时才需唤醒系统,以更新电池的状态,如control B的控制信号所示。 Figure 5 is a conventional method that can be a fixed time interval will wake up the system to update the state of the battery, as shown in FIG controlA control signal; and the new method described in the present embodiment is only in charge of the battery 3. 9V, 3. 7V, 3. 6V when to wake up the system to update the state of the battery, as indicated by the control signal of the control B. 因此从更新次数的比较来看,传统方法远多于本实施例所提供的方法,换言之,本实施例具有较少的更新次数,因而有较佳的省电效果。 So the number of updates from the comparison, the traditional method of far more than the method provided in the present embodiment, in other words, the present embodiment has less number of updates, and thus have a better power savings.

[0048] 今根据图5所示来做举例说明,假设系统工作在正常运作下的耗电量约300mA,而系统闲置在省电模式下的耗电量约为100mA,现以两台嵌入式电子装置的系统作为举例说明,且分别使用传统旧方法与本实施例的新方法来更新电池的状态。 [0048] FIG 5 according to do this illustration, assume that the system power consumption under normal operation work about 300mA, while the system is idle power consumption in the power saving mode is approximately 100mA, are now embedded in two system electronics, as illustrated, and each state using the old method and the conventional method of the present embodiment to update the new embodiment of the battery. 其中传统方法每2秒唤醒系统一次,且系统完成更新电池的状态需1秒;而本实施例的新方法只有当电池降为3. 9V、3. 7V、3. 6V这三种电压时才需更新电池的状态,且系统完成更新电池的状态一样需1 秒。 Wherein a conventional method to wake the system once every 2 seconds, and the completion of the update state of the battery system needs one second; the new embodiment of the method of the present embodiment only when 3 7V, 3 6V battery voltage is reduced to three only 3. 9V,.. need to update the status of the battery, and the battery system to complete the update needs as one second. 另外假设此两台系统所使用的电池特性均相同,因此根据图5所示电池在放电1小时后,电池电量将从充饱的状态降为3. 6V,因此新、旧方法在1小时后的总耗电量差异如下: Further assume that this characteristic of the battery using the two systems are the same, so the battery 5 as shown in FIG. 1 hour post-discharge, battery from the fully charged state is reduced to 3. 6V, thus new and old method after 1 hour the total power consumption differences are as follows:

[0049] 旧方法:3600/(2+1) X (100X2+300X1) = 600000 (mA/s)/3600 = 166. 67 (mA/ hr); [0049] Old Method: 3600 / (2 + 1) X (100X2 + 300X1) = 600000 (mA / s) / 3600 = 166. 67 (mA / hr);

[0050]新方法:(3600-3) X 100+300 X 3 = 360600 (mA/s) /3600 = 100. 17 (mA/hr); [0050] New methods: (3600-3) X 100 + 300 X 3 = 360600 (mA / s) / 3600 = 100. 17 (mA / hr);

[0051] 166. 67-100. 17 = 66. 5 (mA/hr);[0052] 因此从前述计算结果可以清楚得知新、旧方法在总耗电量的差异,本实施例的新方法相对于传统的旧方法可以节省约66. 5 (mA/hr)的总电量消耗,也就是说本实施例可以达到39. 9% (66. 5/166. 67 = 39. 9)的省电,显然本实施例的新方法具有较佳的省电效果。 .
