本申请以2005年3月10日向日本申请的日本专利申请号2005-067818为基础主张优先权,通过参照该申请而在本申请中加以引用。 The present application is based on Japanese Patent Mar. 10, 2005 to Japanese Application No. 2005-067818 claims priority basis, by referring to the application and in this application could be applied.

背景技术 BACKGROUND

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装置。 The prior art, often use electronic devices to an internal lithium ion battery, NiCb batteries, nickel hydrogen batteries and other secondary batteries of the battery pack as a power source such as a video camera or digital camera imaging device, a portable telephone, or a personal computer or the like.

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。 This battery pack used in electronic devices built: for example, a microcomputer (hereinafter also referred to as a microcomputer), used to perform the remaining battery charge calculation or perform communications between the battery as a power source for electronic devices; the peripheral circuits microcomputer; and a built-in micro-computer to perform the remaining battery power computing needs, 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 battery, Japanese Unexamined Patent Publication No. 09-297166 discloses a battery pack described.

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。 In addition, a portable information terminal (PDA: Personal Digital Assistant, a personal digital assistant) or the like of the portable information processing apparatus having a network connection function, with the increase of processing capacity, in order to correspond with the use of electronic billing and other such devices, for confirming the user is performed The user authentication process. 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, implementation of the authentication information communication, based on the result of the authentication acknowledgment, personal and confidential information stored in the portable information processing apparatus is protected between the charging means 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 provided with such a function, there is described in Japanese Patent Laid-Open Publication No. 2004-310387 described.

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。 However, there is a built-in secondary battery to a battery pack for power electronic devices, most of each apparatus using a dedicated battery pack, but a battery pack using a dedicated device on the apparatus body tends to be a cause of breakage, damage, etc. reasons.

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。 In addition, the prior art, performed between the charging means and the portable information processing apparatus control information communication unit, the battery authentication is performed prior to other processing of the battery authentication process is not completed in the battery authentication processing, can not perform other processing.

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。 Moreover, even the same cell, after power is turned, prior to other processing, every time the battery authentication.

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。 In the prior art, unified battery of the same kind used in the authentication process of electronic devices, so people who want to manufacture 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 side and the microcomputer of the battery side of the apparatus large Therefore, a high-speed drive microcomputers, resulting in large power consumption.

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。 In addition, there are the following problems: In the conventional battery pack, loaded with only battery residual quantity display function and the battery authentication processing function in any of a loaded simultaneously has two functions, while the battery residual quantity display and battery authentication processing, the communication system requires two independent devices and batteries, communication line requires two systems, thus leading to high cost of hardware, but also, the drive requires two communication systems, the high cost of software development.

发明内容 SUMMARY

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。 Further, the present invention provides an electronic apparatus, comprising: a device main body, mounting a microcomputer having communication function; and a battery for providing power to the apparatus main body, detachably mounted on the apparatus main body, and having loaded microcomputer communication apparatus main body side serial communication function 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。 The microcomputer uses the electronic apparatus of the present invention, when the power is turned, the microcomputer device main body side from the first serial communication means is mounted on the main body of the battery pack side to obtain information for battery residual quantity display, according to the obtained information display remaining battery power. 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 body side by serial communication from the apparatus main body is mounted on the battery pack side to obtain information for authentication processing, authentication processing based on the acquired information, determines the device connected to the body The battery pack is a regular battery pack; apparatus main body side of the microcomputer performing the authentication processing, according to the information acquired by serial communication from the microcomputer of the battery pack side for battery residual quantity display, and update content of battery residual quantity display .

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。 The present invention is by performing battery authentication does not use coarse battery at the device side, thereby preventing the use of the battery for a battery other than the apparatus body due to breakage, damage and the like.

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。 Further, in the present invention, before the battery remaining usable time began battery authentication processing is not performed and only battery residual quantity display, so the user has a function value of the remaining power of the battery will not be displayed damaged by battery authentication processing.

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。 Further, in the present invention, in a system battery residual quantity display processing and battery authentication processing, eliminating the need to separately means having signal lines between the battery, the hardware cost reduction can be achieved, and, using a communication driver system enough, it is possible to reduce software development costs.

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。 Moreover, in the present invention, the battery authentication handled separately, in the remaining battery power display intermittent treatment, thus not only create poor battery manufacturers, who have malicious difficult to crack the authentication method, and, even without using a high-performance The microcomputer also battery authentication can be performed, thus cutting costs, in addition, even if not in the high-speed operation of the microcomputer battery authentication can be performed, thus saving power consumption.

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。 Further, in the present invention, since battery authentication result is stored, so the start of the second and subsequent power-on from, can be specifically battery residual quantity display processing, protection for the user's immediate value.

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。 Here, FIG. 4 (B) shown in the timing shown in the conventional battery authentication method of battery authentication is performed in the first, and FIG. 4 (C), conventional timing shown only carried Compared to the case of the remaining battery charge display remaining battery time than initially displayed using only battery authentication communication state ST4 slow time, but in the video camera 100, first, the remaining battery charge display, then the authentication process, so Compared with the situation only battery residual quantity display remaining battery time than initially displayed slow time.

即,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。 That is, in the present invention uses a video camera 100, initially only battery residual quantity display processing, after the battery authentication process appears on the LCD section 4 of the remaining battery time, it began to appear in the remaining battery time Even if the additional time battery authentication process, but the user has not changed, the function value displays the remaining battery power will not be damaged because the battery authentication process.

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。 Thus, the present invention uses a video camera 100, even if the battery authentication of users as a direct value of the remaining battery time will not be slower than the time initially displayed.

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1的破损等。 Further, in the video camera 100, the battery residual quantity display battery authentication is performed in parallel, it is impossible to use coarse battery is not genuine, may prevent the use of non-genuine battery can lead to damage of the apparatus body 1 and the like.

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1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。 Further, in the video camera 100, the battery residual quantity display and battery authentication processing using both second microcomputer communication system of the first microcomputer 3 of the camera body 1 side and the battery pack 2 side 7 by time sharing processing performed, so only one communication line can system, the hardware cost can be reduced.

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。 In addition, the camera 100, the battery charge remaining in the same system, display processing and battery authentication processing, which is a system of communication can drive, you can reduce the cost of software development.

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。 In addition, the camera 100, by dividing the battery authentication processing, display remaining battery power in the intermittent treatment progresses, thereby creating poor battery manufacturers and other malicious people find it difficult to crack the authentication method.

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。 Further, in the video camera 100, since battery authentication processing performed separately, even if high performance microcomputer is not used can also be battery authentication, thus cutting costs.

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。 Further, in the video camera 100, since battery authentication processing is divided, it is not high speed, even if the use of the microcomputer can also be battery authentication, it saves the power consumption.

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。 In addition, the camera 100, because saving the authentication processing results, so start the second time after the power is turned on, the remaining battery power can be devoted to the display processing, protecting direct value to the user.

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。 Further, since battery authentication can be used immediately after the video camera 100, therefore, especially in such a video camera or digital camera 100 such imaging apparatus, it is possible to shorten the time for battery replacement, reduce the imaging timing may be missed, can be continuously imaged effect.
