电子装置及其电池模块的认证方法 Electronic device and method of authentication of battery modules

技术领域 Technical Field

[0001] 本发明涉及一种电子装置的电池模块的认证装置及其认证方法。 [0001] The authentication apparatus and authentication method of the present invention relates to an electronic device battery module.

背景技术 Background

[0002] 请參照图1,图I绘示已知的电子装置100的示意图。 [0002] Referring to Figure 1, a schematic view of FIG. I painted known electronic device 100 is shown. 在这种的已知技术领域中,用来连接至电子装置100以提供电カ的电池110中设置有ー个下拉电阻RPL。 In this known art, for connection to the electronic device 100 to provide electrical ka battery 110 is provided with a pull-down resistor ー RPL. 下拉电阻RPL串接在电池110的连接端CNl与接地电压GND间。 RPL pull-down resistor is connected in series between the ground voltage GND terminal CNl battery 110. 而电子装置100中用来进行电池认证的电池认证模块120中则包括上拉电阻RPU、晶体管Ml、电阻RSDl以及处理器121及122。 The electronic device 100 used for battery authentication battery authentication module 120 includes pull-up resistor RPU, transistor Ml, resistance RSDl and a processor 121 and 122. 上拉电阻RI3U连接至电压Vl以及晶体管Ml的栅极,晶体管Ml的漏极则耦接至电压V2以及处理器121,晶体管Ml的源极则耦接至接地电压GND。 RI3U pullup resistor connected to the gate voltage and transistor Ml Vl, the transistor Ml is coupled to the drain and source voltage V2 processor 121, the transistor Ml pole is coupled to the ground voltage GND. 电阻RSDl则串接在端点DT及处理器122间。 Resistance RSDl is connected in series between the endpoints DT and the processor 122. 另外,电池认证模块120还连接至连接端CN2。 In addition, the battery authentication module 120 is also connected to the connecting terminal CN2.

[0003] 当电池110通过其连接端CNl与电池认证模块120所连接的连接端CN2相互连接时,端点DT上的电压会等于电压Vl依据上拉电阻RPU以及下拉电阻RPL的电阻值来进行分压所产生的电压值。 [0003] When the battery 110 is connected by its end CNl battery authentication module 120 is connected to the connecting terminal CN2 are interconnected, the voltage at the terminal DT will be equal to the voltage Vl based on pull-down resistors RPU and the resistor value to be divided RPL Pressure generated voltage value. 此时处理器122则读取端点DT上的电压,以区别电池110的厂牌。 At this point processor 122 reads the voltage at the terminal DT on the label to distinguish the battery 110. 另外,在电池110有效连接至电池认证模块120时,端点DT上的电压会降低并使晶体管Ml关闭。 In addition, the battery 110 is operably linked to a battery authentication module 120, the voltage at the terminal and DT will reduce the transistor Ml is turned off. 因此,处理器121接收到等于电压V2的电压值,并据此判断电池110已经被连接至电子装置100上。 Thus, the processor 121 receives a voltage equal to the voltage value V2, and accordingly determines that the battery 110 has been connected to the electronic device 100.

[0004] 由于在这种已知的电池识别方法下,非原厂的电池仅需要在其中配置ー个与原厂电池中的下拉电阻RPL相同阻值的电阻,就可以使电池认证模块120无法辨识是否为原厂的电池。 [0004] Since in this known battery identification method, non-original batteries which need only be configured with the original battery ー a pull-down resistor RPL equal value resistors, you can make the battery authentication module 120 can not Identification of whether the original battery. 如此ー来,当电子装置100对此种非原厂的电池进行充电的动作时,就有可能因为电压过充而产生安全上的顾虑。 So ー way, when 100 pairs of such non-original battery charging operation of the electronic device, it is possible because overcharge voltage generated safety concerns.

具体实施方式 DETAILED DESCRIPTION

[0035] 请參照图2,图2绘示本发明ー实施例的电子装置200的示意图。 [0035] Referring to Figure 2, Figure 2 illustrates a schematic view of an example of an electronic apparatus 200 of the embodiment of the present invention ー. 电子装置200包括电池模块210以及电池认证模块220。 The electronic device 200 includes a battery module 210 and the battery authentication module 220. 电池模块210具有认证电路211以及识别电阻RPL,其中,识别电阻RPL的一端耦接至參考电压GND,识别电阻RPL的另一端则耦接至认证电路211。 The battery module 210 includes an authentication circuit 211 and an identification resistor RPL, wherein one end of the RPL identification resistor coupled to the reference voltage GND, and the other end of the RPL identification resistor coupled to the authentication circuit 211. 电池认证模块220则具有參考电阻RUP耦接至參考电压VI。 Battery Authentication module 220 has a reference resistor RUP coupled to the reference voltage VI. 其中,电池模块210以及电池认证模块220各具有连接端点CNl以及CN2。 Wherein, the battery module 210 and the battery authentication module 220, and each having a connection end CNl CN2.

[0036] 当电池模块210连接至电池认证模块220时,參考电阻RUP与识别电阻RPL串接于參考电压Vl及GND间。 [0036] When the battery module 210 is connected to the battery authentication module 220, a reference resistor RUP and identification resistor connected in series between the reference voltage RPL Vl and GND. 也就是说,參考电阻RUP与识别电阻RPL耦接的端点DT上的电压,会等于參考电压Vl依据參考电阻RUP与识别电阻RPL的电阻值所进行的分压的結果。 That is, the voltage reference resistor RUP and identification resistor coupled RPL endpoint DT on dividing the result will be equal to the reference voltage Vl RUP according to the reference resistor and the resistance value of the identification resistor RPL conducted.

[0037] 在本实施例中,电池认证模块220依据端点DT上的电压电平来获得电池模块210的类型信息。 [0037] In the present embodiment, the authentication module 220 based on the battery voltage level on the endpoint DT battery module 210 to obtain the type of information. 在此,所谓的类型信息包括电池模块210厂牌、型号及规格等至少其中之一的信息。 Here, the type of information that includes a battery module 210 brands, models and specifications and other information in at least one. 具体一点来说明,由于具有不同类型信息的电池模块210,其内建的识别电阻RPL的大小是不相同的,因此,在当不同类型信息的电池模块210连接至电池认证模块220时,端点DT上的电压电平也会不同。 Specifically described, since the different types of information having the battery module 210, the size of its built-in identification resistor RPL is not the same, therefore, when the different types of information of the battery module 210 is connected to the battery authentication module 220, the endpoint DT voltage level will be different. 因此,电池认证模块220可以由端点DT上的电压电平来获取电池模块210的类型信息。 Therefore, the authentication module 220 may be made of the battery voltage level on the endpoint DT battery module 210 to obtain the type of information.

[0038] 另外,请特别注意的是,电池认证模块220在确知已与电池模块210产生连接后,电池认证模块220会传送认证需求至电池模块210中的认证电路211,并藉此使认证电路211可以通过參考电阻RUP与识别电阻RPL的耦接路径PTl来传送认证信息至电池认证模块220。 [0038] Also, special attention is the battery authentication module 220 has to ascertain the battery module 210 generates a connection, battery authentication module 220 certification requirements will be sent to the battery module 210 in the authentication circuit 211, and thereby enable authentication circuit 211 authentication information may be transmitted through the coupling path PTl reference resistor RUP and recognition RPL resistance to battery authentication module 220. 附帯一提的是,前述的电池认证模块220会传送认证需求至电池模块210中的认证电路211也是通过同样的路径PTl来将认证需求由电池认证模块220传送至认证电路211。 Bands attached mentioning that the foregoing battery authentication module 220 certification requirements will be sent to the battery module 210 is the authentication circuit 211 through the same path to the certification requirements PTl battery authentication module 220 is transmitted to the authentication circuit 211.

[0039] 在此,认证电路211可以是ー种可以传送数字或模拟格式的认证信息至连接端点CNl的电路。 [0039] Here, the authentication circuit 211 may ー species can transmit authentication information to a digital or analog format CNl circuit connection endpoint. 也就是说,认证电路211可以是利用串接的电阻串、可执行编码的集成电路或是电容网络来产生认证信息。 That is, the authentication circuit 211 may be using a serial resistor string, perform coding integrated circuit or capacitor network to generate authentication information. 其中,当认证电路211可以是利用两个不同电平的电压间串接在电阻串,并利用电阻串所产生的分压电压,来提供生认证信息。 Wherein, when the inter-authentication circuit 211 may be using two different levels of voltage in series with the resistor string, and use the divided voltage generated by the resistor string to provide raw authentication information. 或者,认证电路211可以利用可执行编码的集成电路,来提供编码过的数字数据来作为的认证信息。 Alternatively, the authentication coding circuit 211 can perform the integrated circuit, to provide digital data encoded as the authentication information. 亦或是,认证电路211也可以通过电容网络来以对电压进行分压或是倍压的方式,来产生认证信息。 Also, or, authentication circuit capacitor network 211 can also be at a partial pressure or voltage doubler manner voltage to generate the authentication information.

[0040] 由于电池认证模块220与电池模块210所具有的连接端点CN2及CNl皆为单一条导线的连接端点,因此,电池认证模块220与电池模块210间的信息传送可以通过一种所谓的单线连接协议(one-wire protocol)来进行。 [0040] Since the battery authentication module 220 and the battery module 210 has a connection endpoint CN2 and CNl are all single-connection end of a wire, so battery authentication module 220 and the battery module 210 can transmit information through a so-called single-wire Connection Agreement (one-wire protocol) to carry out.

[0041] 所谓的单线连接协议,指的是利用单一条导线来进行两个电子装置间的数据传输。 [0041] The so-called single connection protocol, refers to the use of a single wire for data transmission between two electronic devices. 简单来说,在单线连接协议的架构下,可以将用来进行数据传输的导线保持在被拉高(pull high)的状态。 Simply put, in the framework of a single connection protocol can be used for data transmission wire holding being pulled (pull high) state. 在其中的一个电子装置(例如装置A)要传送数据给另一个电子装置(例如装置B)时,装置A可以通过拉低(pull low)导线上的电压电平一段时间以告知装置B要进行数据的传递。 In which an electronic device (e.g., device A) to transmit data to another electronic device (e.g., device B), device A may be low (pull low) voltage level over time lead to the device B to be informed transferring data. 在装置B确认获知装置A要进行的数据传递动作后,装置A可以通过拉低导线上的电压电平不同的时间来传递不同(逻辑O或逻辑I)的数据。 After the device B Claim apparatus A to be informed of the data transfer operation, device A may be low voltage level at different times on the wire to pass different (logic O or logic I) data.

[0042] 以下请參照图3,图3绘示本发明实施例的电池认证模块220的ー实施方式的示意图。 Please refer to [0042] Figure 3 below, Figure 3 illustrates the present embodiment of the invention, the battery authentication module 220 ー embodiment schematic view of the embodiment. 电池认证模块220除包括參考电阻RUPタト,尚包括主要处理器221、辅助处理模块222以及分压电阻RBAT_ID。 Battery Authentication module 220 in addition to including a reference resistor RUP Tatari Suites, still including the main processor 221, the auxiliary processing module 222 and dividing resistor RBAT_ID. 主要处理器221耦接至參考电阻RUP未耦接參考电压Vl的端点DT0辅助处理模块222则耦接至主要处理器221,且分压电阻RBAT_ID耦接在辅助处理模块222与主要处理器221的耦接路径间,其中,分压电阻RBAT_ID的电阻值小于參考电阻RUP的电阻值。 The main processor 221 is coupled to a reference resistor connected to the reference voltage Vl RUP endpoint DT0 auxiliary processing module 222 is coupled not coupled to the main processor 221, and the voltage divider resistors RBAT_ID coupled auxiliary processing module 222 and the main processor 221 coupled paths, wherein the partial pressure of the resistance RBAT_ID resistance value is less than the resistance value of the reference resistor RUP. 并且,主要处理器221可以利用其通用型的输入输出(General Purpose InputOutput, GPI0)端ロ的一个脚位来耦接至端点DT。 Also, the main processor 221 can use its general-purpose input and output (General Purpose InputOutput, GPI0) ro a pin end to be coupled to the endpoint DT. 并通过这个与端点DT连接的通用型的输入输出)端ロ的ー个脚位来进行数据的传收。 And through this connection with an endpoint DT universal input and output) terminal ro the ー a pin to send and receive data. [0043] 以下将配合图2以及图3,来具体的说明本发明实施例的电子装置200的电池模块210的认证动作。 [0043] The following will meet Figs. 2 and 3 illustrate an electronic device to a specific embodiment of the present invention, a battery module authentication operation 200 210. 首先,当电池模块210被连接至电子装置200吋,辅助处理模块222依据读取端点DT上的电压值,来获取电池模块210的类型信息。 First, when the battery module 210 is connected to the electronic device 200 inches, the auxiliary processing module 222 reads the voltage value based on the endpoint DT, the battery module 210 to obtain the type information. 在此,辅助处理模块222可以是ー个模拟数字转换器,以将模拟格式的端点DT上的电压转换成数字格式,并提供电池模块210利用数字格式的端点DT上的电压来获得电池模块210的类型信息。 Here, the auxiliary processing module 222 may be ー analog-digital converter, the voltage of the endpoint on the DT analog format into a digital format, and provides the battery voltage at the terminal DT module 210 of the digital format to obtain a battery module 210 The type of information.

[0044] 接着,辅助处理模块222提供一个上拉电压VUP至分压电阻RBAT_ID的一端(分压电阻RBAT_ID的另一端耦接至端点DT),并且,在辅助处理模块222所提供的上拉电压VUP稳定后,主要处理器221传送低电平电压至端点DT上,以使得端点DT上的电压电平由等于上拉电压VUP的电压电平,被拉至较低的电压电平(例如等于接地电压)。 [0044] Next, the auxiliary processing module 222 provides an end to pull a voltage dividing resistor RBAT_ID VUP (the other end of the voltage divider resistors RBAT_ID is coupled to the end DT), and, in the pull-up voltage provided by the auxiliary processing module 222 After VUP stability, the main processor 221 to transmit low voltage on the endpoint DT, so that the voltage level on the endpoint DT by pull-up voltage is equal to the voltage level of VUP, pulled to a lower voltage level (for example, equal ground voltage). 在此同时,电池模块210的认证电路221则可以检测到端点DT上的电压被拉低的状态,并藉以获知电池认证模块220所提出的认证需求。 In the meantime, the battery module 210 of the authentication circuit 221 can detect the voltage at the terminal DT is pulled low on state and thereby informed of the proposed battery authentication module 220 certification requirements.

[0045] 值得ー提的是,在本实施例中,參考电阻RUP的电阻值是远大于分压电阻RBAT_ID的电阻值的。 [0045] ー worth mentioning that, in this embodiment, the resistance value of the reference resistor RUP is much greater than the resistance value of the resistor divided RBAT_ID's. 在当辅助处理模块222提供的上拉电压VUP至分压电阻RBAT_ID的一端吋, 端点DT上的电压值几乎是由上拉电压VUP的电压值大小所決定。 Pullup voltage VUP when the auxiliary processing module 222 to the dividing resistor RBAT_ID end of inches, the voltage value on the endpoint DT is almost determined by the pull-up voltage VUP voltage value size. 也就是说,此时的端点DT上的电压值约等于上拉电压VUP的电压。 That is, the voltage value at that time on the endpoint DT pull-up voltage is approximately equal to the voltage VUP. 在另一方面,当端点DT上的电压稳定后,主要处理器221通过传送低电平电压至端点DT上,以拉降端点DT上的电压为等于低电平电压。 On the other hand, when the voltage stability on the endpoint DT, primarily processor 221 by sending low-level voltage to the upper endpoint DT, to pull down the voltage at the terminal DT is equal to the low voltage.

[0046] 另外,为进行静电放电的防护,主要处理器221与端点DT间串接电阻RESD。 [0046] In addition, electrostatic discharge protection, between the main processor 221 and the endpoint DT series resistance RESD.

[0047] 电池模块210的认证电路221在获知电池认证模块220所提出的认证需求后,主要处理器221则改变其耦接參考电阻RUP的端点为输入端点,而认证电路221则可以提供端点DT低电平电压,并利用拉低端点DT上的电压电平来序列地传送认证信息。 [0047] The battery module authentication circuit 221 210 is informed of the proposed battery authentication module 220 certification requirements, changing its main processor 221 is coupled to the reference resistor RUP endpoint input terminal, and authentication circuit 221 can provide endpoint DT low voltage, and use low voltage level on the endpoint DT to sequence transmitted authentication information. 其中,主要处理器221可以利用其通用型的输入输出端ロ的一个脚位来耦接端点DT,并藉以传送电压至端点DT上或接收端点DT上的电压电平。 Among them, the main processor 221 can use its general-purpose inputs and outputs of a ro pin end coupled to DT, and thereby transfer voltage to the voltage level on the endpoint DT DT or on the receiving endpoint.

[0048] 此外,在认证需求结束后,辅助处理模块222可通过监测端点DT上的电压变化,来获知电池模块210的电压变化曲线。 [0048] In addition, after the certification requirements, auxiliary processing module 222 may monitor the voltage variation on the endpoint DT, to learn the battery module voltage curve 210.

[0049] 附帯ー提的是,辅助处理模块222提供的上拉电压VUP的动作以及接收端点DT上的电压的动作可以通过主要处理器221的ー个通用型的输入输出端ロ的一个脚位来完成。 [0049] attached Bands ー mentioning that the operation voltage of the auxiliary processing module 222 provides a pull-up voltage VUP action and on the receiving end DT through the main processor 221 ー a general-purpose inputs and outputs of a pin ro to complete. 换句话说,辅助处理模块222是可以内建在主要处理器221中的。 In other words, the auxiliary processing module 222 can be built into the main processor 221.

[0050] 以下參照图4A及图4B,图4A及图4B分别绘示电池认证模块与电池模块间的信息传送的波形图,在图4A及图4B中,电池认证模块与电池模块间是利用单线连接协议来进行数据的传递。 [0050] with reference to FIGS. 4A and 4B, the FIG. 4A and 4B respectively illustrate waveform diagram battery authentication information transfer between the module and the battery module, in FIGS. 4A and 4B, the authentication between the battery module and the battery module is the use of a single connection protocol for transferring data. 其中,在图4A的绘示中,在时间区间TO中,辅助处理模块提供上拉电压VUP并使端点DT的电压电平維持在约等于上拉电压VUP的电压电平。 In Fig. 4A illustrates the time interval TO, the auxiliary processing module provides a pull-up voltage VUP and DT endpoint voltage level is maintained at about equal to the pull-up voltage VUP voltage level. 在时间区间Tl中,主要处理器则通过提供低电平电压来持续拉低端点DT的电压电平。 In the time interval Tl, the main processor through providing sustained low-level voltage to the low voltage level DT endpoint. 在时间区间T3中,则是电池模块在时间区间Tl接收并获知认证需求已被启动,而对应以拉低端点DT的电压电平来传送认知(acknowledge)信号至电池认证模块。 In the time interval T3, the battery module is received and needs to know the authentication has been started in the time interval Tl, which corresponds to the low voltage level of the endpoint DT transmitted cognition (acknowledge) signal to the battery authentication module.

[0051] 在此请注意,在时间区间Tl及T2间,主要处理器耦接端点DT的端点被设定为输入端点,藉以接收由电池模块所主导产生的端点DT上的电压变化,以接收认证电路所传送的认证信息,并通过所接收到的认证信息来对电池模块进行认证的动作。 [0051] In this note, the time interval between T2 and Tl, the main processor coupled to DT endpoint endpoint is set to the input end, thereby receiving endpoint voltage change DT dominated by the battery module generated on, to receive authentication information transmitting circuit and received by the authentication information to authenticate the operation of the battery module.

[0052] 在图4B的绘示中,认证电路可以通过拉低端点DT的电压的时间长短来传送逻辑信号的认证信息。 [0052] In Figure 4B illustrates, the authentication circuit the authentication information may be transmitted logic signal DT by pulling the end of the duration of the voltage. 以波形410为例,认证电路持续拉低端点DT的电压ー个时间区间TL,以藉以传送逻辑信号“ I”。 In waveform 410, for example, sustained low endpoint authentication circuit voltage ー DT time interval TL, so as to transmit a logic signal "I". 相対的,以波形420为例,认证电路持续拉低端点DT的电压ー个时间区间TH,以藉以传送逻辑信号“O”。 Dui phase to the waveform 420, for example, continued low endpoint authentication circuit voltage ー DT time interval TH, to thereby transfer logic signal "O". 其中,时间区间TH长于时间区间TL。 Wherein the time interval is longer than the time interval TH TL.

[0053] 当然,上述的逻辑信号“I”或“O”与端点DT的电压被拉低的时间区间的长短的对应关系是可以被变更,并非必需固定而不能改变。 [0053] Of course, the corresponding relationship between the logic signal or "O" with the endpoint voltage DT "I" is pulled down the length of the time interval can be changed, is not required but can not change fixed.

[0055] 另外,作为模拟数字转换器的辅助处理模块223或224也可以在认证需求结束后,通过监测端点DT上的电压变化,来获知电池模块210的电压变化曲线。 [0055] In addition, an analog-digital converter auxiliary processing module 223 or 224 may be performed after the end of the certification requirements, by monitoring the voltage variation on the endpoint DT to learn the battery module voltage curve 210.

[0058] 综上所述,本发明除依据电池模块与电池认证模块的连接点上的电压大小来获知电池模块的类型信息,更通过由电池模块传送认证信息至电池认证模块。 [0058] In summary, the present invention is in addition based on the size of the junction voltage battery modules and battery authentication modules to learn the battery module type information, but also through the authentication information transmitted from the battery module to the battery authentication module. 并藉此由电池认证模块对电池模块进行更准确的认证,如此一来,仅有完全符合规格的原厂的电池模块可以通过认证,非原厂的电池模块将不会通过认证而被误用。 And thereby the battery authentication module battery module more accurate authentication, this way, only in full compliance with the specifications of the original battery module can be certified, non-original battery module will not be misused by certified . 有效排除因使用到不良的电池而导致的电子装置的损坏的现象。 Effectively eliminate damage due to inappropriate use of the battery caused by the phenomenon of electronic device.
