拥有工具识别电路的无线电动工具
技术领域
本发明涉及无线电动工具，且更具体的是拥有工具识别电路的无线电动工具。
背景技术
广泛种类的电动工具被用于不同的应用中例如建筑应用、火灾和营救应用等等。一些无线电动工具的例子包括但不受限于：无线电钻、无线圆锯、无线往复锯、无线砂磨机、无线螺丝起子和闪光灯。无线电动工具使用一个可充电电池包为其提供能量使其工作。可以容易地将该可充电电池包从无线电动工具移除并将其连接至一个外置电池充电器以达到充电的目的。
该电池包包括一个或多个电池。电池包也包括监测电路，该监测电路用来监测参数，例如电池电压值、放电电流和充电电流。存在着很多不同的无线电动工具和电池包。一个电池包可以应用于多种无线电动工具中。然而没有办法向电池包通报有关于该无线电动工具的任何细节。因此，需要一个工具识别电路，用来向一个插入的电池包通报该无线工具的特定数据。

图6所示为一个实施例的相关操作的流程图。
尽管下文的具体实施方式将参考所示实施例进行，但许多选择、修改和变动对于本领域技术人员是明显存在的。因此，本发明旨在涵盖广泛范围。
具体实施方式
图1所示为无线电动工具100的透视图。无线电动工具100被表示为一个无线电钻，并且在本文相关的实施例中也将如此表示。然而无线电动工具100可以是任何类型的无线电动工具，包括但不受限于：无线圆锯、无线往返锯、无线砂磨机、无线螺丝起子和闪光灯。无线电动工具包括一个可充电电池包102，用来提供能量使工具100工作。可以容易地从无线电动工具100上移除可充电电池包102并将其连接至一个外置电池充电器以达到充电的目的。无线电动工具100还包括一个扳机104。对于电钻，使用者压和放扳机104以控制卡盘142的速度。对于其他工具例如闪光灯，使用者可以设置扳机的位置以控制闪光灯的亮度。
图2所示为图1无线电动工具的电源系统200的电路图。电源系统200包括电池包102、负载240、扳机104和工具识别(ID)电路230。本文任何实施例所使用的“电路”包括：例如单个固定电路、可编程电路、状态机电路，和/或储存由可编程电路执行的指令的固件，或这些电路的任意组合。
电池包102包括一个或多个电池203，用来为系统200提供能量。电池203在一个实施例中可为锂离子电池。电池包102通过放电开关209向负载240提供能量。在一个实施例中，放电开关可为一个场效应晶体管(FET)。电池包102也包括监测和控制电路208。监测和控制电路208为每个电池测量一个或多个电池包电流、温度和电池电压值。
监测电路208比较所测值和相关阈值，并且如果所测值中的一个大于或等于相关阈值监测电路208就识别一个过载状态。例如，过载状态可以是一个大于或等于一个表示最大放电电流的阈值的放电电流。在另一个例子中，过载状态可以是一个提供至电池203的大于或等于一个表示最大充电电流的阈值的充电电流值。在另一个例子中，过载状态可以是一个电池的大于或等于一个电压阈值的电压值。在另一个实施例中，过载状态可以是一个元件的大于或等于一个温度阈值的温度。当检测到过载状态时监测电路208就会提供一个输出控制信号用来保护电源系统200的元件。该输出控制信号被提供至电池包102的一个或多个开关，或被当作一个控制输入通过路径127提供至外置于电池包102的其他电路。在一个实施例中，该输出控制信号被提供至放电开关209用来断开开关209，其中过载状态为一个来自电池203的大于或等于一个最大放电电流阈值的放电电流。
监测和控制电路208还响应扳机104的位置提供一个控制信号至放电开关209。该控制信号在一个实施例中可为一个脉冲宽度调制(PWM)信号218，并且放电开关209响应PWM信号218的占空比控制该放电电流。PWM信号218在一个固定频率工作，例如5到10千赫兹(KHz)。随着PWM信号的占空比增加，放电开关209的闭合时间也增加，因此提供至负载240的放电电流值就增加。类似地，随着PWM信号的占空比减小，放电开关209的闭合时间就减少，因此提供至负载240的放电电流值就减小。
工具识别电路230提供一个工具识别信号至监测和控制电路208。该工具识别信号表示无线电动工具的特定数据，例如特殊无线电动工具的功率参数。例如，该工具识别信号可表示该特殊无线电动工具的一个最大放电电流。例如，工具识别信号还可表示该无线电动工具的热负载点。在一个实施例中，监测和控制电路208提供一个刺激信号至工具识别电路230，并且响应该刺激信号工具识别信号被提供。
工具识别电路230也帮助确认电池包102是否被适当地连接至无线电动工具，并确认该电池包是否支持该特殊无线电动工具的类型。例如，如果电池包102没有被适当地连接至该便携式电动工具，工具识别电路230就不会提供一个工具识别信号。作为响应，电池包102就拒绝提供放电电流，除非它接收到一个适当工具识别信号，因而提高了系统的安全性。
通用的电池包可以连接至不同的无线电动工具，但只能支持某些选择的工具。电池包误连接至错误的无线电动工具将引起工具性能的退化或产生安全问题。更优越的是，工具识别电路230提供了一个表示该特殊无线电动工具的类别的工具识别信号。如果电池包102不支持该工具，那么电池包将拒绝放电电流并提供一个表示该事件的指示，这样进一步提高了系统的安全性。
图2A所示为图2工具识别电路230的一个实施例230a。工具识别电路230a包括一个简单的固定电阻250，该电阻有一个固定的电阻值。该固定电阻值表示该特殊无线电动工具的特性。例如，特性可为该特殊无线电动工具的一个热过载点。该固定电阻250接收一个来自监测和控制电路208的刺激信号，例如一个电流信号。然后工具识别电路230响应该刺激信号并有效地把该工具识别信号提供回监测和控制电路208。固定电阻250的电阻值，和一个已知的刺激信号，提供一个可预知的响应，该响应可被测量并和一个特殊工具特性相互关联。
图2B所示为图2工具识别电路的另一个实施例230b。该工具识别电路包括便宜的无源元件，例如并联的电容252和电阻254。
图2C所示为与图2A和图2B的工具识别电路230a/230b一同作用的监测和功率控制电路208a的一个实施例。监测和控制电路包括一个电流源270、开关SW1、模拟-数字转换器(ADC)272、处理器285和存储器287。电流源270提供一个相对小的恒流，例如1毫安，达到一些最大电压Vmax。ADC 272读取电流源270的电压输出，并提供输出至处理器285。当电池包102a没有连接至该无线电动工具时开关SW1是闭合的。开关SW1由处理器285直接或间接控制。由于电流源270无负载，电流源270的电压输出将增加至它的最大电压值Vmax。
当电池包102a连接至该无线电动工具时，电流源270提供一个刺激信号，例如一个电流信号至工具识别电路230a/230b。接着由于电阻280的阻性负载将被连接至电流源270，工具识别电路根据固定电阻280的电阻值有效地提供一个工具识别信号至监测和控制电路208a。电阻280可为图2A实施例中的单独的电阻250或图2B实施例中的电阻254。电阻280的值控制电流源270的从由ADC272转换并提供至处理器285的Vmax开始的电压降。接着处理器285，例如通过从存储器287存取数据，使电流源的被测电压值或电流源的从Vmax开始的电压降与一个特殊无线电动工具特性相关联。一个电动工具特性可表示一个过载电流限制。如果电阻的被测值太小，例如小于100欧姆，这可被视为Vsense端口222与Vpack端口290的短路，那么工具被禁止工作。
由于图2B的实施例拥有并联的电容252和电阻254(或图2C的280)，处理器285在解码取自电阻280的第一个工具特性信息之后使开关SW1断开。这将导致电容252通过电阻280放电。处理器285接着通过例如从存储器287存取数据，使被测放电时间和一个第二无线电动工具特性例如无线电动工具的一个热过载点相关联。如果电容252的充电时间被监测并与一个工具特性相关联，也可通过连接至无线电动工具的电池包102实现这一目的。
工具识别电路230的其他实施例包括其他方法，例如在工具识别电路230中使用一个微控制器，该微控制器可以与监测和控制电路208通信。在其他实施例中也可以使用一个数字串行总线用于工具识别电路230和监测和控制电路208之间的通信。
图3所示为图2电源系统200相关的电源系统300的电路图。图3中与图2相似的元件以相同的参数标注，所以为了清晰在此省略任何重复的描述。图3的负载240a可为一个马达340，用来通过一个相连的齿轮系(未示出)驱动元件142。例如，元件142可为图1电钻的用来控制电钻钻头的卡盘。更优越的是可以去除一个无线电动工具中在马达340输入侧的传统速度控制开关。在它的位置上，放电开关209控制放电电流从而控制由马达340驱动的元件142的速度。
速度选择电路316接收一个来自扳机104表示扳机104位置即表示无线电动工具的元件142的期望速度的信号。然后速度选择电路316提供一个表示期望速度的输入信号至电池包102的监测和控制电路208。接着监测和控制电路208提供一个控制信号至放电开关209，通过控制提供至马达340的放电电流来控制元件142的速度。
在无线电动工具工作时，使用者摁压扳机104至一个期望的量来控制元件142的速度。速度选择电路316响应扳机104的位置提供一个输入信号至监测和控制电路208。监测和控制电路208包括一个PWM发生器，该发生器响应速度选择电路316的输入信号更改PWM信号218的占空比。PWM信号218在一个固定频率工作，例如5至10千赫。当PWM信号的占空比增加时，放电开关209的闭合时间也增加，因此无线电动工具的元件142的速度就增加。类似地，当PWM信号的占空比减少时，放电开关209的闭合时间减少，这样电动工具的元件142的速度就减少。在一个例子中，PWM信号的占空比可以有一个从大约10％(慢速)至75％(快速)的变化。
图4所示为图1无线电动工具的电源系统的另一个电路图。放电开关209可为场效应晶体管Q1。场效应晶体管Q1可为一个金属氧化物半导体场效应晶体管(MOSFET)，例如一个p沟道MOSFET(PMOS)或一个n沟道MOSFET(NMOS)。电池包102b也包括多个电池203-1、203-2、...、203-(n-1)和203-n。电池包102b为多个负载提供能量，包括表示为一个马达绕组的负载240b。二极管410与场效应晶体管Q1并联以允许充电电流流入电池203-1、203-2、...、203-(n-1)和203-n，并且防止来自电池的放电电流。电池包102a包括可选择状态指示器406，用来提供来自监测和控制电路208的不同被测状态的指示信号。
速度选择电路316a包括一个可变电阻454，该电阻与另一个电阻452串联。可变电阻454可为一个电位计。可变电阻454的电阻值响应扳机104的位置而被设置。因此可变电阻454的电阻值就表示元件142(见图3)的期望速度。电阻452的电阻值表示一个最大放电电流速度。考虑到低成本无线电动工具，例如闪光灯，速度选择电路316a允许便宜的放电限制和/或可变的电源控制。监测和控制电路208使用第三电池包端口422接收来自速度选择电路316a关于期望速度的信息。然后监测和控制电路208会在一个特定的占空比提供一个PWM信号218以取得所期望的速度。
图5所示为监测和控制电路208的另一个实施例208b。监测和控制电路208b包括开关网络502、模拟-数字转换器(ADC)504、处理器506、驱动器508、存储器534、保护电路524和PWM发生器510。处理器506命令开关网络502选择一个特定电池203-1、203-2、...、203-(n-1)和203-n来监测。然后每个电池各自的模拟电池电压值通过开关网络502被取样。被取样的模拟信号然后被ADC 504转换为相关的数字信号并被提供至处理器506。因此处理器506接收来自ADC 504的代表各个电池203-1、203-2、...、203-(n-1)和203-n的电压值的数字信号，并将这些信号与不同的电压阈值做比较。
例如，当电池包102充电时，监测和控制电路208a监测电池电压值以判断是否有电池电压值超过一个过压阈值。如果有电池电压超过阈值，那么处理器506将采取一些预防举措。例如，通过提供一个信号至驱动器508断开一个特定的开关从而使充电停止。例如，在电池包102放电时，监测和控制电路208a监测电压值以判断是否有电池电压值小于一个欠压阈值。如果有电池电压小于欠压阈值，处理器506将会采取一些预防举措。例如，通过提供一个信号至驱动器508断开一个特定的开关从而使放电停止。
处理器506也命令开关网络502闭合一个开关(例如图2C的开关SW1)以使ADC 504监测电流源270(见图2C)的电压。然后电流源270提供一个刺激信号，例如一个电流信号至工具识别电路，且接着该工具识别电路有效地提供一个工具识别信号至监测和控制电路208b，该信号可以通过例如从存储器534存取数据使不同被测值与不同的工具特性相关联而被测并且与一个特殊工具的特性相关联。
处理器506也接收来自保护电路524的其他信号。保护电路524通常监测流入(充电模式)或流出(放电模式)电池包102的电流以发现不同的电流过载状态，例如过流或短路状态，并且向处理器506警报这些情况使其采取预防措施。例如，一个电流检测元件例如检测电阻404(图4)可在流入或流出电池包的电流值变化时向保护电路524提供一个表示该电流值的信号。保护电路524比较该电流值和不同的阈值，然后向处理器506提供一个信号通知处理器一个过流状态或一个短路状态，这样处理器506就可以采取预防措施了。
PWM发生器510接收一个来自速度选择电路316、316a的信号，并向放电开关例如场效应晶体管Q1(见图4)提供一个输出PWM信号。处理器506允许PWM信号控制放电开关的状态直到一个过载状态发生为止。当过载状态发生时，例如额外的放电电流，处理器506使PWM发生器510失效，并命令驱动器508断开放电开关。这样监测和控制电路208a可以更优越地使PWM发生器510在适当的时候控制放电开关209，并且当过载状态被监测到时监测和控制电路208a也可以使PWM发生器510失效并断开放电开关。
图6所示为一个实施例的工作流程图600。操作602包括连接一个电池包至一个无线电动工具。操作604包括一旦该电池包被适当地连接至该无线电动工具就提供一个来自无线电动工具的工具识别信号至该电池包，该工具识别信号表示该无线电动工具的特定数据。
更优越的是工具识别电路使电池包可以接收一个特殊工具的数据，否则将没有办法得知这些数据。此类数据包括代表该特殊无线电动工具的最大放电电流，或该特殊工具的一个热过载点以指出一个连接的数据。另外，工具识别电路可以提供一个有用的次要指示：电池包已经被正确地插入适当的无线电动工具中。在没有适当的工具识别信号时，电池包将拒绝放电从而改进了系统的安全性。
本文所使用的术语与措辞是揭示内容的术语，但没有局限性，并且在采用这些术语和措辞时不排除其他与本文所展示和描述的特征(或部分特征)相似的等价物，应该明白在权利要求范围内本发明可能有多种修改。本发明还可能存在其他的修改、变动和选择。因此，权利要求旨在覆盖所有这些等价物。
