背景技术 Background technique

[0003] 现有技术中,经常使用以内置有锂离子电池、NiCb电池、镍氢电池等二次电池的电池组作为电源的摄像机或数码照相机这样的摄像装置、便携式电话、或个人计算机等电子 [0003] prior art, often used with the built-in lithium ion battery, NiCb batteries, nickel hydrogen batteries, secondary batteries as a power source of the battery pack camcorder or digital still camera imaging device such as a portable phone, a personal computer or other electronic

目.ο Head .ο

[0004]这种用于电子装置的电池组内置有:例如,微型计算机(以下也简称为微计算机),用于执行电池的剩余电量计算或执行与将该电池作为电源的电子装置之间的通信;该微计算机的外围电路;以及内置的该微计算机执行电池的剩余电量计算等所需要的、电池组电池的状态检测电路等。 [0004] Such a battery pack for an electronic device built: for example, a microcomputer (hereinafter also referred to as a microcomputer) for performing the remaining battery charge calculation or perform the battery as a power source for electronic devices between communication; peripheral circuits of the microcomputer; and a built-in micro computer to perform the remaining battery power calculation required, the battery cell state detection circuit. 作为这种电池组,有日本特开平09-297166号公报中所记载的电池组。 As such a battery pack, Japanese Unexamined Patent Publication No. 09-297166 discloses described battery pack.

[0005] 此外,便携式信息终端(PDA:Personal Digital Assistant,个人数字助理)等便携式信息处理装置具有网络连接功能,随着处理能力的提高,为了与使用这些装置的电子结算等对应,而执行用于确认用户的用户认证处理。 [0005] In addition, a portable information terminal (PDA: Personal Digital Assistant, a personal digital assistant) and other portable information processing apparatus having a network connection function, with the increase of the processing capacity in order to correspond with electronic settlement using such devices, is performed by to confirm the user authentication process of the user. 例如,在充电装置与便携式信息处理装置内的控制单元之间执行关于认证的信息通信,根据认证确认的结果,对存储在便携式信息处理装置内的个人及秘密信息进行保护。 For example, the implementation of the authentication information and communication, according to the results certified confirmation of personal and confidential information stored in the portable information processing apparatus for protection within and between the charging device and the portable information processing apparatus control unit. 作为具备这种功能的装置,有日本特开2004-310387号公报中所记载的装置。 As an apparatus with such a function, there are means JP 2004-310387 discloses described.

[0006]但是,在以内置有二次电池的电池组为电源的电子装置中,多数是每台装置使用专用的电池组,但是在该装置上使用专用的电池组往往成为导致装置主体的破损、损坏等的原因。 [0006] However, there is a built-in secondary battery battery-powered electronic devices, each device uses mostly dedicated battery pack, but used on the device-specific battery packs often become damaged resulting in the apparatus body , damage and other causes.

[0007]此外,现有技术中,在充电装置和便携式信息处理装置内的控制单元之间执行信息通信、进行电池的认证时,是在其他处理之前进行电池的认证处理,在未完成电池认证处理时,不能进行其他的处理。 When [0007] In addition, the prior art, performed between the charging device and a portable information processing apparatus of the information communication control unit, the battery authentication is performed prior to other processing of the battery authentication process is not completed in the battery authentication processing, other processing can not be performed.

[0008]此外,即便是相同的电池,在接通电源后、进行其他的处理之前,每次都要进行电池认证。 [0008] Moreover, even the same cell, until after power, to perform other processing, every time the battery authentication.

[0009]在现有技术中,统一进行使用于同种电子装置的电池的认证处理,所以想要制造假冒电池的人很容易破解电池的认证方法。 [0009] In the prior art, unified use of the battery of the same kind of electronic device authentication process, so people want to create counterfeit batteries is very easy to hack battery authentication method. 此外,还存在以下问题:因为装置侧(set side)及电池侧的微型计算机的负载大,所以需要高速驱动的微型计算机,导致成本高,并且,因为装置侧及电池侧的微型计算机的负载大,所以需要高速驱动微型计算机,导致消耗功率大。 In addition, there is a problem: since the load of the microcomputer device side (set side) and the battery side is large, it requires high-speed drive of the microcomputer, resulting in high cost, and because the load of the microcomputer device side and a battery side by a , it is necessary to drive high-speed microcomputer, resulting in large power consumption.

[0010]此外,还存在以下问题:在现有的电池组中,仅装载有电池剩余电量显示功能和电池认证处理功能中的任意一种,同时装载有两种功能、同时进行电池剩余电量显示和电池认证处理,则需要两个独立的装置和电池的通信系统,通信线需要两个系统,从而导致硬件的成本高,而且,通信用的驱动器需要两个系统,软件开发成本高。 [0010] In addition, there is a problem: the conventional battery pack, loaded with only battery residual quantity display and battery authentication processing function in any one, while loaded with two functions, while the battery residual quantity display and the battery authentication processing, the communication system requires two independent devices and battery systems require two communication lines, thereby resulting in the high cost of hardware, but also, the drive requires two communication systems, the high cost of software development.

发明内容 SUMMARY

[0011]鉴于上述技术问题,本发明的目的在于提供一种不增大微型计算机的负载、可同时装载电池剩余电量显示功能和电池认证处理功能两种功能的电池剩余电量显示方法及电子装置。 [0011] In view of the above technical problems, an object of the present invention is to provide a microcomputer without increasing the load can be loaded simultaneously display the remaining battery power and battery authentication processing function of two functions battery residual quantity display method and electronic device.

[0012] —种电子装置中的电池剩余电量显示方法,所述电子装置包括:装载具有通信功能的微型计算机的装置主体;以及电池组,用于向该装置主体提供电源,其装卸自由地安装该装置主体上,并装载有具有与装置主体侧的微型计算机进行串行通信的通信功能的微型计算机。 [0012] - electronic device in the battery residual quantity display method, said electronic device comprising: a device body microcomputer loaded with a communication function; and a battery for providing power to the device body, which is removably mounted on the apparatus main body, and having a microcomputer loaded with a main body side apparatus communicate serially across a communication function of a microcomputer. 该方法为:在装置主体侧的微型计算机接通电源时,首先通过串行通信从安装在该装置主体上的电池组侧的微型计算机取得用于电池剩余电量显示的信息,根据取得的信息进行电池剩余电量显示。 The method comprises: when the body side microcomputer device is powered first by serial communication from the microcomputer of the battery pack is installed on the side of the apparatus main body to obtain information for battery residual quantity display, according to the obtained information battery residual quantity display. 接着,装置主体侧的微型计算机通过串行通信从安装在该装置主体上的电池组侧的微型计算机取得用于认证处理的信息,根据取得的信息进行认证处理以判断连接于该装置主体上的电池组是否为正规电池组。 Then the microcomputer, the microcomputer of the apparatus main body side through a serial communication from a device mounted on the main body of the battery pack side to obtain information for authentication processing, authentication processing based on the acquired information to determine whether the apparatus is connected to the body battery pack is a regular battery. 装置主体侧的微型计算机在进行认证处理后,根据通过串行通信从电池组侧的微型计算机取得的用于电池剩余电量显示的信息,更新电池剩余电量显示的内容。 After the microcomputer device body side during the authentication process, according to information obtained through serial communication from the microcomputer side of the battery pack for battery residual quantity display updates the display of remaining battery power.

[0013]另外,本发明提供一种电子装置,包括:装置主体,安装具有通信功能的微型计算机;以及电池组,用于向该装置主体提供电源,装卸自如地安装在装置主体上,并装载有具有与装置主体侧的微型计算机进行串行通信的通信功能的微型计算机。 [0013] Further, the present invention provides an electronic device, comprising: a device body, mounting a microcomputer having communication function; and a battery for providing power to the apparatus main body, is detachably mounted on the apparatus main body, and loading apparatus having a body side and a microcomputer communicate serially across a communication function of a microcomputer. 采用本发明的电子装置在接通电源时,装置主体侧的微型计算机首先通过串行通信从安装在该装置主体上的电池组侧的微型计算机取得用于电池剩余电量显示的信息,根据取得的信息进行电池剩余电量显示。 Microcomputer electronic device of the present invention, when power is turned on, the microcomputer device body side from the first through the serial communication device mounted on the side of the main body of the battery pack is used to obtain information on the remaining battery charge displays, based on the acquired information battery residual quantity display. 接着,装置主体侧的微型计算机通过串行通信从安装在该装置主体上的电池组侧的微型计算机取得用于认证处理的信息,根据取得的信息进行认证处理,判断连接于该装置主体上的电池组是否为正规电池组;装置主体侧的微型计算机在进行认证处理后,根据通过串行通信从电池组侧的微型计算机取得的用于电池剩余电量显示的信息,更新电池剩余电量显示的内容。 Then the microcomputer, the microcomputer of the apparatus main body side through a serial communication from a device mounted on the main body of the battery pack side to obtain information for authentication processing, authentication processing based on the acquired information, determines the device connected to the body battery pack is a regular battery pack; microcomputer device body side after performing the authentication processing, according to information obtained through serial communication from the microcomputer side of the battery pack for battery residual quantity display updates the display of remaining battery power .

[0014] 本发明通过进行电池的认证,在装置侧不会使用粗劣的电池,从而可以防止由于使用适合的电池以外的电池引起的装置主体的破损、损伤等。 [0014] The present invention is carried out by the battery authentication, the device does not use coarse side of the battery, the battery can be prevented due to the use of suitable means other than the battery body due to breakage, damage and the like.

[0015]而且,在本发明中,在电池的剩余可使用时间开始出现之前不进行电池的认证处理而仅仅进行电池剩余电量显示,所以对用户来说,具有价值的电池的剩余电量显示的功能不会因为电池认证处理而受损。 [0015] In the present invention, before the battery remaining usable time began without battery authentication processing only battery residual quantity display, so the user, has a function of the value of the remaining power of the battery display the battery authentication process will not be damaged.

[0016]另外,在本发明中,在一个系统内进行电池剩余电量显示处理和电池认证处理,从而不需要单独地具有装置和电池之间的信号线,可实现硬件成本削减,而且,通信驱动器使用一个系统就足够了,所以可削减软件的开发成本。 [0016] In the present invention, a system battery residual quantity display processing and the battery authentication processing, eliminating the need to have a separate device and the signal lines between the battery, the hardware cost reduction can be achieved, and that a communication driver use a system is sufficient, it is possible to reduce software development costs.

[0017]此外,在本发明中,将电池认证处理分开,在电池的剩余电量显示处理的间歇时进行,从而不仅制造粗劣电池的厂家等具有恶意的人难以破解认证的方法,而且,即使不使用高性能的微型计算机也可以进行电池认证,所以削减了成本,此外,即使不在高速运作微型计算机也可以进行电池认证,所以节省了功率消耗。 [0017] In the present invention, the battery authentication process separately, the remaining battery power display batch processing will be, thus not only create poor battery manufacturers and other malicious people difficult to crack the authentication method, and, if not high performance microcomputer can also be battery authentication, so cut costs. in addition, even if the operating speed is not the microcomputer can also be battery authentication, saves power consumption.

[0018]此外,在本发明中,因为保存有电池认证结果,所以从第二次以后的电源接通时开始,可以专门进行电池剩余电量显示处理,保护对于用户的直接价值。 [0018] In the present invention, since battery authentication result stored, so the start of the second after the power is turned on from, it can be devoted to the battery residual quantity display processing, protection for the user's immediate value.

[0019]本发明的其他目的、根据本发明得到的具体优点,可以从以下参照附图说明的实施方式中进一步明确。 [0019] Other objects of the present invention, according to the specific advantages of the present invention obtained can be further clarified with reference to the embodiments illustrated in the drawings.

[0078]接着,照相机主体I侧的第一微型计算机3和电池组2侧的第二微型计算机7变成电池剩余电量显示通常通信状态ST2,进行18个“电池剩余电量修正值”的通信(步骤SA15〜步骤SA32、步骤5815〜步骤5832)。 [0078] Next, the first microcomputer 3 of the camera body and I side of the battery pack 2 side of the second microcomputer 7 into a battery residual quantity display ordinary communication state ST2, conducted 18 "battery residual quantity correction value 'communication ( step SA15~ step SA32, step 5815~ step 5832).

[0079]接着,照相机主体I侧的第一微型计算机3根据取得的14个+18个=32个“电池剩余电量修正值”,计算电池组2的剩余可使用时间(步骤SA33)。 [0079] Next, the first microcomputer 3 of the camera body side according to I 14 +18 = 32 "battery residual quantity correction value" made in calculating the battery pack 2 remaining usable time (step SA33).

[0080]接着,照相机主体I侧的第一微型计算机3在液晶显示部4上显示电池组2的剩余可使用时间(步骤SA34)。 [0080] Next, the first microcomputer 3 of the camera body side I displayed on the LCD display unit 4 of the battery pack 2 remaining usable time (step SA34).

[0081]接着,照相机主体I侧的第一微型计算机3和电池组2侧的第二微型计算机7变成电池认证通信状态ST4,进行仅一个“装置侧和电池侧共同具有的信息”的通信(步骤SA35、步骤SB33)。 Communications [0081] Next, the first microcomputer 3 of the camera body and I side of the battery pack 2 side of the second microcomputer 7 into a battery authentication communication state ST4, conducted only a "device side and a battery side commonly have information" (step SA35, step SB33).

[0082]接着,照相机主体I侧的第一微型计算机3和电池组2侧的第二微型计算机7变成电池剩余电量显示通常通信状态ST2,进行仅一个“电池剩余电量修正值”的通信(步骤SA36、步骤SB34)。 [0082] Next, the second microcomputer first microcomputer 3 of the camera body and I side of the battery pack 2 side 7 into battery residual quantity display ordinary communication state ST2, perform a "battery residual quantity correction value" communication only ( step SA36, step SB34).

[0083]而且,照相机主体I侧的第一微型计算机3和电池组2侧的第二微型计算机7在电池认证通信状态ST4中反复重复共8个“装置侧和电池侧共同具有的信息”,直至通信结束(步骤SA35〜步骤SA36、步骤SB33〜步骤SB34)。 [0083] Also, the first microcomputer 3 of the camera body and I side of the battery pack 2 side of the second microcomputer 7 of the battery authentication communication state ST4, repeating a total of eight "device side and a battery side commonly have" until the end of communication (step SA35~ step SA36, step SB33~ step SB34).

[0084]接着,照相机主体I侧的第一微型计算机3读出保存在照相机主体I侧的非易失性存储器5中的共同信息,与从电池组2侧的第二微型计算机7得到的信息进行比较(步骤SA37)0 [0084] Next, the first microcomputer 3 of the camera body side I read I saved in the camera body side of the non-volatile memory 5 together information from the battery pack 2 side and the second microcomputer 7 of the information obtained (step SA37) 0

[0085]而且,照相机主体I侧的第一微型计算机3在两个信息一致时判断为是正品电池,在非易失性存储器5中存储表示“电池认证结束”和表示“插入的电池为正品”的信息(步骤SA38)。 [0085] Also, the first microcomputer 3 of the camera body side I both agreed it is determined that the information is genuine battery, non-volatile memory 5, that "battery authentication end" and that "the inserted battery is genuine "message (step SA38). 然后,变成“电池剩余电量显示通常通信状态” ST2,只进行“电池剩余电量修正值”的通信。 Then, into a "battery residual quantity display ordinary communication state" ST2, only "battery residual quantity correction value" communication.

[0086]而且,照相机主体I侧的第一微型计算机3在两个信息不一致时判断为是假冒电池,然后在液晶显示部4上显示“当前插入的电池为假冒电池,请使用正品电池”的信息,同时在非易失性存储器5中存储表示“电池认证结束”的信息和表示“插入的电池不是正品”的信息,经过一定时间后,将照相机主体I的电源断开(步骤SA39)。 [0086] Also, the first microcomputer 3 of the camera body side I judgment in two inconsistent information to be counterfeit batteries, and then displayed on the liquid crystal display unit 4 "counterfeit battery currently inserted battery, please use genuine battery" information, while in the non-volatile memory 5, that "battery authentication end" message and indicates "battery inserted is not genuine" message after a certain time, the camera body I is powered off (step SA39).

[0087]在该摄像机100中,由照相机主体I侧的第一微型计算机3和电池组2侧的第二微型计算机7执行图3的流程所示的处理,如图4(A)所示的时序所示,当装置主体I的电源接通时,首先,经由电池剩余电量显示初始通信状态STl变成电池剩余电量显示通常通信状态ST2,最初,在液晶显示部4上显示电池的剩余可使用时间,然后,交替切换电池认证通信状态ST4和电池剩余电量显示通常通信状态ST2,当认证处理结束时,反复进行电池剩余电量显示通常通信状态ST2,更新电池剩余电量显示的内容。 [0087] In the video camera 100, 3 and the second microcomputer 7 of the battery pack 2 side performed by the first microcomputer side of the camera body I flow processing shown in FIG. 3, as shown in Figure 4 (A) of timing, when the device is powered on the subject I, first of all, via a battery residual quantity display initial communication state STl into battery residual quantity display ordinary communication state ST2, initially, on the liquid crystal display unit 4 displays remaining usable battery time, and then, alternately switching the battery authentication communication state ST4 and the battery residual quantity display ordinary communication state ST2, when the certification process is finished, repeatedly battery residual quantity display ordinary communication state ST2, update the battery residual quantity display content.

[0088]这里,如图4中(B)所示的时序所示的在最先进行电池认证的现有电池认证方法中,与如图4中(C)所示的时序所示的现有的仅仅进行电池剩余电量显示的情况相比,电池的剩余可使用时间比最初显示的时间仅慢电池认证通信状态ST4的时间,但是在该摄像机100中,首先进行电池剩余电量显示,然后进行认证处理,所以与仅仅进行电池剩余电量显示的情况相比,电池的剩余可使用时间不比最初显示的时间慢。 [0088] Here, as shown in FIG. 4 (B), the timing shown in the conventional battery authentication method of battery authentication may be performed for the first, and in FIG. 4 (C) shown in the timing shown in the conventional compared with the case only battery residual quantity display of the battery remaining usable time than initially displayed only slow battery authentication communication state ST4 time, but in the video camera 100, first battery residual quantity display, and then authenticate treatment, as compared with the case where only battery residual quantity display of the battery remaining time slower than the time initially displayed.

[0089] S卩,在采用了本发明的摄像机100中,最初仅仅进行电池剩余电量显示处理,在液晶显示部4上出现电池的剩余可使用时间后进行电池认证处理,所以到开始出现电池的剩余可使用时间的时间即使追加了电池认证处理,但对用户来说也没有改变,有价值的电池剩余电量显示的功能也不会因为电池认证处理而受损。 [0089] S Jie, in using the camera of the present invention, the 100, initially only battery residual quantity display processing, the battery authentication processing after appearing on the liquid crystal display unit 4 Battery remaining usable time, so to begin a battery of time remaining usable time of the battery, even if the additional authentication process, but the user has not changed, valuable battery residual quantity display function will not be damaged because the battery authentication processing.

[0090]这样,在采用了本发明的摄像机100中,即使进行电池认证,作为用户的直接价值的电池的剩余可使用时间也不会慢于最初显示的时间。 [0090] Thus, the present invention uses a video camera 100, even when battery authentication, as a direct user value of the remaining battery time will not be slower than the time initially displayed.

[0091]另外,在该摄像机100中,与电池剩余电量显示并行地进行电池认证,所以不可能使用不是正品的粗劣的电池,可以防止使用非正品的电池而导致装置主体I的破损等。 [0091] In addition, the video camera 100, and the remaining battery power display battery authentication is performed in parallel, it is impossible to use coarse battery is not genuine, it can prevent the use of non-genuine batteries and lead to breakage of the apparatus body I like.

[0092] 此外,在该摄像机100中,电池剩余电量显示和电池认证处理两者都是使用照相机主体I侧的第一微型计算机3和电池组2侧的第二微型计算机7的通信系统,通过分时处理进行,所以只需要一个系统的通信线即可,可以削减硬件的成本。 [0092] In addition, in 100, the battery authentication process between the camera and display the remaining battery power are using the camera side of the body I first microcomputer 3 and the battery pack 2 side of the second microcomputer 7 of the communication system by sharing processing, so only need a communication line to the system, can reduce hardware costs.

[0093] 此外,在该摄像机100中,在相同系统内进行电池剩余电量显示处理和电池认证处理,从而通信驱动器是一个系统即可,可以削减软件的开发成本。 [0093] In addition, the video camera 100, within the same system battery residual quantity display processing and the battery authentication processing, which is a communication system to drive, can reduce software development costs.

[0094] 此外,在该摄像机100中,通过分割电池认证处理,在电池剩余电量显示处理的间歇时进行,从而制造粗劣电池的厂家等怀有恶意的人难以破解认证方法。 [0094] In addition, the video camera 100, the authentication process by dividing the battery, the battery remaining display processing is carried out intermittently, thereby producing poor battery manufacturers and other malicious people find it difficult to crack the authentication method.

[0095]此外,在该摄像机100中,因为电池认证处理分开进行,所以即使不使用高性能微型计算机也可以进行电池认证,所以削减了成本。 [0095] Further, in the video camera 100, since battery authentication processing carried out separately, even if high performance microcomputer is not used can also battery authentication, thus cutting costs.

[0096]此外,在该摄像机100中,因为电池认证处理分开进行,所以即使不是高速使用微型计算机也可以进行电池认证,所以节省了电力消耗。 [0096] Further, in the video camera 100, since battery authentication processing carried out separately, even if the microcomputer is not high velocities can also battery authentication, it saves the power consumption.

[0097]此外,在该摄像机100中,因为保存了认证处理结果,所以第二次以后的电源接通时开始,可以专门进行电池剩余电量显示处理,保护对用户的直接价值。 [0097] In addition, the video camera 100, since saving the authentication processing results, so the start of the second after the power is turned on, can be devoted to the battery residual quantity display processing, protection of direct value to users.

[0098]此外,因为电池认证后可以马上使用摄像机100,因此,尤其是在这种摄像机100或数码照相机这样的摄像装置中,可以缩短更换电池时的时间,减少错过摄像时机的可能,具有可以连续摄像的效果。 [0098] Furthermore, since battery authentication can be used immediately after the video camera 100, therefore, especially in such a digital camera or a video camera 100 such as the image pickup apparatus can shorten the time for battery replacement, reduce the imaging timing may be missed, can have continuous imaging results.
