背景技术
在现有技术中，智能卡等电子设备的线圈与芯片直接相连，将智能卡放置在射频场中，智能卡的芯片电路消耗场能量与读卡器(POS机、NFC手机等)进行通信。在实际应用中，为了节约智能卡的体积，一般不会在在智能卡中设置电池，因此，现有智能卡除了芯片电路一般不会设置耗电元器件。
随着智能卡的发展，在相关技术中，出现需要在智能卡中设置除芯片电路以外的其它耗电元器件。例如，在智能卡上设置显示屏，可以显示交易过程中的信息等。在这种情况下，需要给智能卡提供电能。因此，可能需要在智能卡中设置取电电路，该取电电路从线圈获取电能。在这种情况下，如果芯片电路与取电电路共用线圈则可能无法取得最佳取电效率，而增加一个取电线圈则增大电路难度和成本，同时还会影响智能卡与设备通讯。因此，通信线圈与取电线圈共用必须有效将线圈和芯片之间的射频载波断开。如何将线圈和芯片之间的射频载波断开是相关技术中需要解决的技术问题。

具体实施方式
下面结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明的保护范围。
在本发明的描述中，需要理解的是，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或数量或位置。
下面将结合附图对本发明实施例作进一步地详细描述。
实施例1
本实施例提供了一种通断装置，该通断装置可以应用在具有线圈的电子设备上，用于连通或断开线圈与电子设备的某个功能模块(例如，具有非接触功能的芯片)的连接。
图1为本实施例提供的通断装置的结构示意图，如图1所示，该通断装置主要包括：交流输入端100、交流输出端110、通断模块120、第一隔直组件130、以及第二隔直组件140。其中，线圈的一端与交流输入端100连接，而线圈的另一端可以接地，交流输出端110可以与电子设备的某个功能模块(例如，具有非接触功能的芯片)连接，电子设备的该功能模块与线圈共地，该功能模块的具体结构本申请并不作限定。
其中，如图1所示，通断模块120可以包括：第一端口121、第二端口122、第三端口123、第四端口124以及控制端125，其中，第三端口123与直流电源(VCC)电连接，第四端口124与地端连接，控制端125用于接收控制信号；通断模块120用于在控制信号的控制下导通或断开第三端口123和第四端口124之间的通路，其中，在第三端口123和第四端口124之间的通路导通的情况下，第一端口121与第二端口122之间的通路导通，从而使得 从交流输入端100到交流输出端110的通路导通，在第三端口123和第四端口124之间的通路断开的情况下，第一端口121与第二端口122之间的通路断开，从而使得从交流输入端100到交流输出端110的通路断开。在本实施例中，通断模块120可以包括一个导通模块，第三端口123和第四端口124之间的通路与第一端口121与第二端口122之间的通路可以共用该导通模块，该导通模块可以在通断模块120导通第三端口123和第四端口124之间的通路时导通，在通断模块120断开第三端口123和第四端口124之间的通路时断开，从而可以通过控制第三端口123和第四端口124之间的通路的通断控制导通模块的通断，通过该导通模块的通断达到控制第一端口121与第二端口122之间的通路的通断的目的。
第一隔直组件130连接在交流输入端100与第一端口121之间。其中，第一隔直组件130用于隔断第一端口121与交流输入端100之间的直流信号，传输第一端口121与交流输入端100之间的交流信号。通过第一隔直组件130，在直流电源到地之间的通路连通时，直流信号不会通过第一隔直组件130传输到交流输入端100，从而不会影响线圈的功能。
第二隔直组件140连接在交流输出端110与第二端口122之间。其中，第二隔直组件140用于隔断第二端口122与交流输出端110之间的直流信号，传输第二端口122与交流输出端110之间的交流信号。通过第二隔直组件140，在直流电源到地之间的通路连通时，直流信号不会通过第二隔直组件140传输到交流输出端110，从而不会影响线圈与交流输出端110之后的模块的通讯。
通过本实施例提供的上述通断装置，可以设置在电子设备的线圈与某个功能模块之间，连通或断开线圈与电子设备的某个功能模块(例如，具有非接触功能的芯片)的连接，从而使得该功能模块可以与其它功能模块(例如，取电电路)共用同一个线圈，节约成本。
在本发明实施例的一个可选实施方案中，如图2所示，通断模块120还可以包括：第一负载126、第二负载127、控制模块128以及第一单向导通模块129。
其中，控制模块128与控制端125连接，且控制模块128连接在第三端口123与第一负载126之间，或者控制模块128连接在第四端口124与第二负载127之间，用于在控制信号的控制下导通或断开第三端口123和第四端口124之间的通路。即在本实施例中，控制模块128可以连接在第三端口123与第一负载126之间，通断直流电源与第一负载126之间的电连接(如图2所示)，也可以连接在第四端口124与第二负载127之间，通断第二负载127与地之间的电连接。具体本实施例不作限定。
在本发明实施例的一个可选实施方案中，控制模块128可以包括：第一连接端、第二连接端和控制端。其中，第一连接端与第三端口123电连接，第二连接端与第一负载126电连接；或者，第一连接端与第二负载127电连接，第二连接端与地电连接。控制端用于接收控制信号，并配置成根据控制信号控制第一连接端和第二连接端断开或导通。采用该可选实施 方案提供的方式，使得控制模块128即可以通过现有的器件实现，也可以通过集成芯片实现，扩展了控制模块128的实现方式。
在本发明实施例的一个可选实施方案中，控制模块128可以为NMOS管，其漏极(D)作为控制模块128的第一连接端，其源极(S)作为通断模块的第二连接端，其栅极(G)作为通断模块的控制端。在栅极(G)输入的控制信号的情况下，通断源极(S)与漏极(D)之间的电连接。当然，该控制模块128也可以为PMOS管，其各端连接参照PMOS管的导通条件来设定，这里不做限制。采用MOS管实现控制模块128，可以简化电路实现方式，节约成本。
第一单向导通模块129连接在第一负载126与第二负载127之间，以及第一端口121与第二端口122之间，用于在第三端口123和第四端口124之间的通路的导通的情况下，导通第一端口121与第二端口122之间的通路，在第三端口123和第四端口124之间的通路的断开的情况下，断开第一端口121与第二端口122之间的通路。即在本实施例中，第一单向导通模块129具有这样的功能：在第三端口123与第四端口124的通路导通的情况下，第一单向导通模块129相当于一个具有很小阻值的电阻，交流输入端100输入的交流信号可以通过第一隔直组件130、第一单向导通模块129和第二隔直组件140传输到交流输出端110；而当在第三端口123与第四端口124的通路断开的情况下，第一单向导通模块129相当于一个具有很大阻值的电阻，等效于断开，交流输入端100输入的交流信号不能通过第一单向导通模块129传输到交流输出端110，即交流输入端100到交流输出端110的通路断开。
在本实施例的一个可选实施方式中，第一单向导通模块129可以包括：第一PIN二极管。即第一单向导通模块129可以采用PIN二极管实现。PIN二极管在关断时，具有良好的关断特性，在断开时，等效为一个0.2pF电容，可以阻断交流输入端100与交流输出端110之间的交流信号，即阻断从交流输入端100到交流输出端110的载波信号。PIN二极管在控制导通时，等效为一个电阻，电阻值与导通电流成反比，导通电流越大，电阻越小，交流信号可以从交流输入端100传输到交流输出端110。在该可选实施方式中，第一单向导通模块129采用PIN二极管实现，电路结构简单，并且，成本也比较低廉。当然，并不限于，第一单向导通模块129除了可以采用PIN二极管以外，还可以采用其它方式实现，例如，采用集成芯片实现，具体本实施例不作限定。
在本发明实施例的一个可选实施方案中，为了保证交流输入端100连接的线圈的谐振Q值，第一负载126与第二负载127的阻值相同，且，第一负载126和第二负载127的阻值大于预定值。在具体应用中，第一负载126和第二负载127可以为电阻，例如，第一负载126和第二负载127可以为阻值为1.6K欧的电阻。当然，并不限于此，在实际应用中，第一负载126和第二负载127还可以为其它具有一定阻值的元器件或组件，具体本实施例不作限定。
其中，第一负载126和第二负载127的阻值可以根据第一单向导通模块129采用的PIN二极管的导通条件确定，即第一负载126和第二负载127的阻值满足以下条件：在第三端口123和第四端口124之间的通路导通的情况下，在满足第三端口123和第四端口124之间的通路的电流不小于第一单向导通模块129采用的PIN二极管的导通电流的条件下，其阻值最大。
在本发明实施例的一个可选实施方案中，该装置还可以包括：滤波组件，其中，滤波组件的一端电连接在直流电源与第三端口123的连接点，另一端接地。作为一种可选方式，滤波组件可以为电容或其他可以滤波的组件，本实施例不做限制。通过该滤波组件对直流电源提供的电能进行储能，可以有效去掉从第三端口123接入的直流电源的高电平信号中的毛刺，使高电平信号平滑。
在具体应用中，上述第一隔直组件130和第二隔直组件140可以采用容量大于预定值(即，该预定值使得该电容可以达到隔直的作用，且能导通加载到两端的连接，例如，0.2pF)的电容来实现，当然，并不限于此，在具体应用中，也可以其他可以隔离直流的组件实现，具体本实施例不作限定。
图3为本实施例提供的一种可选地通断装置的电路原理示意图，如图3所示，本实施例中，交流输入端TA与电容C39、PIN二极管D29、电容C40以及交流输出端LA依次串联，其中，PIN二极管D29的负极与电容C39连接，正极与电容C40连接。电阻R12一端连接在D29与C40的连接点上，另一端与直流电源连接，电阻R13一端连接在C39与D29的连接点上，另一端与NMOS管Q8(可以采用FDV301型号的NMOS管)的D极连接，NMOS管Q8的S极接地，NMOS管Q8的G极与控制端连接，用于接收控制信号(CTRL)，NMOS管Q8在控制信号的控制下导通或断开，从而使从直流电源到地的通路导通或断开。电容C36一端连接在直流电源与电阻R12的连接点上，另一端与地连接。在从直流电源到地的通路导通的情况下，由于PIN二极管的特性，在控制导通时，等效为一个电阻，因此，从交流输入端TA输入的交流信号可以通过D29传输到交流输出端LA，而且，由于电容具有隔直通交的功能，因此，从直流电源出来的直流信号不会通过电容C39和C40流到交流输入端TA和交流输出端LA，从而不会影响交流信号的传输。在从直流电源到地的通路断开的情况下，由于PIN二极管的特性，在断开时，等效为一个0.2pF电容，可以阻断交流输入端TA与交流输出端TB之间的交流信号，即阻断从交流输入端TA到交流输出端TB的载波信号。
在上述实施例中，电容C36、C39和C40可以采用10nF的电容。电阻R12和R13可以采用阻值为1.6K欧的电阻，当然，并不限于此，在实际应用中，也可以采用其它类似的器件。

即在本实施例中，第二单向导通模块4202具有这样的功能：在第三端口423与第四端口424的通路导通的情况下，第二单向导通模块4202相当于一个具有很小阻值的电阻，交流输入端400的第一端401输入的交流信号可以通过第一隔直组件430、第二单向导通模块4202和第二隔直组件440传输到交流输出端410的第一端411；而当在第三端口423与第四端口424的通路断开的情况下，第二单向导通模块4202相当于一个具有很大阻值的电阻，等效于断开，交流输入端400的第一端401输入的交流信号不能通过第二单向导通模块4203传输到交流输出端410的第一端411，即交流输入端400的第一端401到交流输出端410的第一端411的通路断开。相似的，第三单向导通模块4205具有这样的功能：在第三端口423与第四端口424的通路导通的情况下，第三单向导通模块4205相当于一个具有很小阻值的电阻，交流输入端400的第二端402输入的交流信号可以通过第三隔直组件450、第三单向导通模块4205和第四隔直组件460传输到交流输出端410的第二端412；而当在第三端口423与第四端口424的通路断开的情况下，第三单向导通模块4205相当于一个具有很大阻值的电阻，等效于断开，交流输入端400的第二端402输入的交流信号不能通过第三单向导通模块4205传输到交流输出端410的第二端412，即交流输入端400的第二端402到交流输出端410的第二端412的通路断开。
在本发明实施例的一个可选实施方案中，第二单向导通模块4203可以包括：第二PIN二极管；第三单向导通模块4205可以包括：第三PIN二极管。即第二单向导通模块4203和第三单向导通模块4205可以采用PIN二极管实现。PIN二极管在关断时，具有良好的关断特性，在断开时，等效为一个0.2pF电容，可以阻断交流输入端400与交流输出端410之间的交流信号，即阻断从交流输入端400到交流输出端410的载波信号。PIN二极管在控制导通时，等效为一个电阻，电阻值与导通电流成反比，导通电流越大，电阻越小，交流信号可以从交流输入端400传输到交流输出端410。在该可选实施方式中，第二单向导通模块4203和第三单向导通模块4205采用PIN二极管实现，电路结构简单，并且，成本也比较低廉。当然，并不限于，第二单向导通模块4203和第三单向导通模块4205除了可以采用PIN二极 管以外，还可以采用其它方式实现，例如，采用集成芯片实现，具体本实施例不作限定。
在本发明实施例的一个可选实施方案中，为了保证交流输入端400连接的线圈的谐振Q值，第一负载4201、第二负载4202与第三负载4204的阻值相同，且，第一负载4201、第二负载4202和第三负载4204的阻值大于预定值。在具体应用中，第一负载4201、第二负载4202和第三负载4204可以为电阻，例如，第一负载4201、第二负载4202和第三负载4204可以为阻值为1.6K欧的电阻。当然，并不限于此，在实际应用中，第二负载4201、第二负载4202和第三负载4204还可以为其它具有一定阻值的元器件或组件，具体本实施例不作限定。
其中，第一负载4201、第二负载4202与第三负载4204的阻值可以根据第二单向导通模块4203和第三单向导通模块4205采用的PIN二极管的导通条件确定，即第一负载4201、第二负载4202与第三负载4204的阻值满足以下条件：在第三端口423和第四端口424之间的通路导通的情况下，在满足第三端口423和第四端口424之间的通路的电流不小于第二单向导通模块4203和第三单向导通模块4205采用的PIN二极管的导通电流的条件下，其阻值最大。
在本发明实施例的一个可选实施方案中，该装置还可以包括：滤波组件，其中，滤波组件的一端电连接在直流电源与第三端口423的连接点，另一端接地。作为一种可选方式，滤波组件可以为电容或其他可以滤波的组件，本实施例不做限制。通过该滤波组件可以有效去掉从第三端口423接入的直流电源的高电平信号中的毛刺，使高电平信号平滑。
在具体应用中，上述第一隔直组件430、第二隔直组件440、第三隔直组件450和第四隔直组件460可以采用容量大于预定值(即，该预定值使得该电容可以达到隔直的作用，且能导通加载到两端的连接，例如，0.2pF)的电容来实现，当然，并不限于此，在具体应用中，也可以其他可以隔离直流的组件实现，具体本实施例不作限定。
图6为本实施例提供的通断装置的一种可选地通断装置的电路原理示意图，如图6所示，本实施例中，交流输入端的第一端TA与电容C39、PIN二极管D29、电容C40以及交流输出端的第一端LA依次串联，电阻R12一端连接在D29与C40的连接点上，另一端与直流电源连接，电阻R13一端连接在C39与D29的连接点上，另一端与PIN二极管D30与电容C43的连接点连接，其中，PIN二极管D29的负极与电容C39连接，正极与电容C40连接。交流输入端的第二端TB与电容C41、PIN二极管D30、电容C43以及交流输出端的第二端LB依次串联，其中，PIN二极管D30的负极与电容C41连接，正极与电容C43连接。电阻R16的一端与电容C41与PIN二极管D30的连接点连接，另一端与NMOS管Q8的D极连接，NMOS管Q8的S极接地，NMOS管Q8的G极与控制端连接，用于接收控制信号(ANNT_CTRL)，NMOS管Q8在控制信号的控制下导通或断开，从而使从直流电源到地 的通路导通或断开。在从直流电源到地的通路导通的情况下，由于PIN二极管的特性，在控制导通时，等效为一个电阻，因此，假设当前交流输入端的第一端TA的交流信号为正半周，则从交流输入端的第一端TA输入的交流信号可以通过D29传输到交流输出端的第一端LA，而从交流输出端的第二端LB回流的交流信号可以通过D30回流到交流输入端的第二端TB，从而使得从交流输入端到交流输出端的整个回路通，实现交流信号的传输。而且，由于电容具有隔直通交的功能，因此，从直流电源出来的直流信号不会通过电容C39和C40流到交流输入端的第一端TA和交流输出端的第一端LA，也不会通过电容C41和C43流到交流输入端的第二端TB和交流输出端的第二端LB，从而不会影响交流信号的传输。在从直流电源到地的通路断开的情况下，由于PIN二极管的特性，在断开时，D29和D30分别等效为一个0.2pF电容，可以阻断交流输入端TA与交流输出端TB之间的交流信号，即阻断从交流输入端TA到交流输出端LB的载波信号。
