Description

电子设备、通道切换的控制方法及控制电路 技术领域
本申请涉及计算机技术领域，尤其涉及电子设备、通道切换的控制技术。
背景技术
不同系统都有各自的优点，基于软件兼容、使用不同的系统等需求，越来越多的用户为电子设备安装双系统，厂商也积极研制生产具有双系统的电子设备，特别是两个系统能够同时运行的电子设备(以下简称双系统电子设备)，以吸引更多用户。而要使两个系统能够同时运行，目前采用的方法主要是使用两个主板，每个主板安装一个系统，由于每个系统拥有一个独立的中央处理器(Central Processing Unit，CPU)，从而两个系统能够同时运行。
以目前常见的具有windows系统和Android系统的双系统电子设备为例，每个系统均可能需要通过外设接口与外设传输数据，目前通常在外设接口与两个操作系统之间设置有切换器，在需要时将外设接口从其中一个操作系统的通道切换到另一个操作系统的通道。
由于windows系统一些功能是基于Android系统来驱动的，例如屏幕显示数据的功能，需要Android系统始终处于运行状态，windows系统才能实现显示功能。但是Android系统经常需要接入加密外设(例如加密狗)对系统进行解密，当window系统需要连接外设时，切换器会将连接加密狗的通道切换到window系统的通道，导致Android系统被锁定，从而整机被锁定无法使用。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
在本申请使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本申请可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
本申请所涉及的电子设备具有两个操作系统，每个系统配置一个主板及中央处理器，因而两个操作系统能够同时运行。操作系统包括Windows系统、Unix系统、Netware系统、Linux系统、Mac系统、Android系统、iOS系统等，两个操作系统的类型可以相同也可以不同，本申请的电子设备通过提供两种操作系统，可以增加电子设备的适用性，每一操作系统可以为用户提供不同的应用环境。操作系统需要与外设连接时，一般是通过外设接口进行连接，由于每一操作系统具有独立的主板及中央处理器，因此，每一操作系统均有相应的接口用于连接外设。
如图1所示的电子设备100，第一操作系统110可以通过外设接口131与外设191连接，第二操作系统120可以通过外设接口132与外设192连接、通过外设接口133与外设193连接，当第二操作系统120中该类接口的数量有限，不能直接与外设接口132、外设接口133连接时，可以通过集线器141扩展接口数量。然而，该设计方式下，虽然电子设备100的接口模块130具备3个外设接口，但是，第一操作系统110只能使用外设接口131，第一操作系统120只能使用外设接口132、外设接口133。当用户在第一操作系统110使用外设191后， 切换到第二操作系统120仍希望使用外设191时，需要手动将外设191插到外设接口132或外设接口133中，才能在第二操作系统120中使用外设191，接口模块130的利用率低，而且使用不便捷。
通过增加一个切换设备即可解决上述问题，如图2所示，与图1相比仅增加了1个多端切换器242，多端切换器242根据第一操作系统210的控制指令进行切换，在使用第一操作系统210时，多端切换器242连通接口模块230与第一操作系统210间的通道，切换系统到第二操作系统220时，多端切换器242连通接口模块230与第二操作系统220间的通道。然而，由于接口模块230中的外设接口231、外设接口232、外设接口233均与多端切换器242连接，多端切换器242每次切换都会同时改变外设接口231、外设接口232、外设接口233连通的通道，且第一操作系统210发送的用于控制多端切换器242切换的控制指令也简单，仅用于控制多端切换器242切换到与当前使用的操作系统连通，不能根据实际使用需求切换通道。例如，当用户从第一操作系统210发送数据到外设291中，未发送完毕时切换到第二操作系统220，多端切换器242随之切换，中断了外设291与第一操作系统210的通路，数据发送终止。
图3a是本申请一示例性实施例示出的一种电子设备的结构示意图；如图3a所示，该电子设备300包括接口模块330、切换模块340、第一操作系统310和第二操作系统320，接口模块330通过切换模块340与第一操作系统310或第二操作系统320连接，切换模块340根据第一操作系统310的控制指令切换接口模块330与第一操作系统310或第二操作系统320之间的通道；
第一操作系统310在与接口模块330连通的状态下，检测到接口模块330与第二操作系统320的连接请求时，控制切换模块340连通接口模块330与第二操作系统320的通道，并确定是否控制切换模块340断开接口模块330与本操作系统的通道。
接口模块330中外设接口的数量可以任意设置，为便于描述，本实施例中以接口模块330包含3个外设接口(外设接口331、外设接口332和外设接口333)为例进行说明。
电子设备300开机时，第一操作系统310和第二操作系统320均启动运行，通常会设置开机默认使用的系统，或在开机时提供选择界面，根据用户的指令选择使用的系统。在当前使用的为第一操作系统310时，第一操作系统310与接口模块330连通，接口模块330与第二操作系统320的连接请求相当于用户要切换到第二操作系统320，第一操作系统310根据与接口模块330连接的外设的情况发送切换指令，以控制切换模块340连通接口模块330与第二操作系统320的通道，并确定是否控制切换模块340断开接口模块330与本操作系统的 通道。显然，控制指令可以由第一操作系统310或第二操作系统320发出，或者由第一操作系统310和第二操作系统320共同控制切换模块340的切换，为了便于描述及控制方便，本实施例选择控制切换模块340进行切换的控制指令由第一操作系统310发出。可以直接由第一操作系统310控制切换模块340的切换，也可以如图3b所示，由控制器350根据第一操作系统310的控制指令控制切换模块340，由于电子设备300的开关机键(图中未求出)等是通过控制器350进行控制的，因此通过扩展原有控制器350的功能即可控制切换模块340，且切换模块340需要根据控制指令保持连接的状态，通过控制器350进行控制的方式能够极大的降低功耗，且无需增加元器件。
第一操作系统310在检测到切换系统的指令时，需要控制切换模块340进行切换，以使接口模块330与第二操作系统320连通，但是，接口模块330与第一操作系统310是否能够断开还需要视情况而定，本申请一实施例中，第一操作系统310确定是否控制切换模块340断开接口模块330与本操作系统的通道的方式包括以下任一种：
第一操作系统310若检测到与本操作系统连接的外设为解密外设，则控制切换模块340不断开接口模块330与本操作系统的通道；
第一操作系统310若检测与本操作系统连接的外设处于持续通信状态，则控制切换模块340不断开接口模块330与本操作系统的通道。
如前所述，当第一操作系统310与外设391持续通信时通路断开，则通信终止，接收的数据可能不完整，因此，第一操作系统310发送的控制指令会保持处于持续通信状态的通道不断开，当然，还可以在持续通信结束时控制切换模块340切换通道使外设391与第二操作系统320连通。有些程序加密后需要连接解密外设(例如加密狗)才能正常运行，为了便于描述，此处以目前常见的具有windows系统(第二操作系统320)和Android系统(第一操作系统310)的电子设备300为例，由于windows系统一些功能是基于Android系统来驱动的，例如屏幕显示数据的功能，需要Android系统始终处于运行状态，windows系统才能实现显示功能。当电子设备300的Android系统加密后，只有在Android系统与解密外设连接时电子设备300才能正常使用，当外设接口332连接的外设392为解密外设时，第一操作系统310会控制外设接口332保持与本操作系统的通道连通，即便切换系统时也会控制切换模块340不断开接口模块330与本操作系统的通道，避免出现Android系统与解密外设断开后锁定导致整机锁定无法使用的情况。
显然，要实现本申请的方案，需要切换模块340为不同的外设接口架设不同的通道，使接口模块330中的外设接口都能与第一操作系统310、第二操作系统320连通，又能独立对 每一外设接口所处的通道进行切换。通道设计方案形式各异，只要能达到对每一外设接口所处的通道进行独立切换即可，接下来将具体介绍几种方案。
图4是本申请又一示例性实施例示出的一种电子设备400的结构示意图；切换模块440包括单端切换器441、442、443及多端切换器444，单端切换器441与外设接口431连接，单端切换器442与外设接口432连接，单端切换器443与外设接口433连接，第一操作系统410、多端切换器444均与单端切换器441、442、443连接；第一操作系统410、第二操作系统420均与多端切换器444连接；
单端切换器441、442、443根据第一操作系统410的控制指令连通外设接口431、432、433与第一操作系统410或多端切换器444之间的通道，多端切换器444根据第一操作系统410的控制指令连通单端切换器441、442、443与第一操作系统410或第二操作系统420之间的通道；
第一操作系统410在检测到本操作系统与解密外设通过多端可切换通道连通时，控制切换模块440连通解密外设与本操作系统之间的单端可切换通道；
第一操作系统410在与接口模块430连通的状态下，检测到接口模块430与第二操作系统420的连接请求时，控制切换模块440连通接口模块430与第二操作系统420的通道，并控制切换模块440不断开解密外设、持续通信状态的外设与本操作系统的通道；
其中，单端可切换通道是不通过多端切换器444建立的通信通道；多端可切换通道是通过多端切换器444建立的通信通道。
如图4所示，外设491通过外设接口431、单端切换器441、多端切换器444与第一操作系统410连接的通道为多端可切换通道，外设491通过外设接口431、单端切换器441与第一操作系统410连接的通道为单端可切换通道。
如图5所示，当电子设备400开机时，若不需要连接解锁外设解锁时，第一操作系统410(Android系统)控制切换模块440连通接口模块430与当前使用的操作系统间的通道，若需要连接解锁外设解锁时，则控制接口模块430通过多端可切换通道与Android系统连通，当检测到外设接口431中插入了外设491时，判断该外设491是否为解锁外设，当该外设491是解锁外设时，电子设备400解锁，由于多端可切换通道还控制着其它外设接口的通道，为了不影响其它外设接口的正常使用，控制单端切换器441切换，使外设491通过单端可切换通道与Android系统连通，且在后续切换操作系统时，均控制单端切换器441保持当前通道不断开。
由于解锁外设可能被插在外设接口431、432、433中的任意一个，若外设接口431、432、433没有可以区分位置的标志，则还需要通过判断解锁外设插入的是哪个外设接口，一实施例采用的方式是第一操作系统410通过控制器450依次向单端切换器441、442、443发送切换指令，当控制器450控制单端切换器441切换后，解锁外设即通过单端可切换通道与Android系统连通，即解锁外设与外设接口431连接，则无需再控制单端切换器442、443进行切换。
外设接口432、433仍通过多端可切换通道与第一操作系统410连通，当切换到第二操作系统420时，控制切换模块440与第二操作系统420连通，当然，如果外设492和/或外设493与第一操作系统410处于持续通信状态，则先控制切换模块440不切换，直到外设492、493与第一操作系统410的持续通信状态结束时再切换；或者询问用户是否强制切换，根据用户触发的指令控制切换模块440是否切换。通过上述方式即可达到根据实际使用需求控制通道进行切换的目的，且可以独立控制各外设接口的通道。
图6是本申请又一示例性实施例示出的一种电子设备600的结构示意图；切换模块640包括与外设接口631连接的单端切换器641、与外设接口632、633连接的多端切换器642；第一操作系统610、第二操作系统620均与单端切换器641连接，第一操作系统610、第二操作系统620均与多端切换器642连接；
单端切换器641及多端切换器642根据第一操作系统610的控制指令切换接口模块630与第一操作系统610或第二操作系统620之间的通道；
第一操作系统610在与接口模块630连通的状态下，检测到接口模块630与第二操作系统620的连接请求时，控制切换模块640连通接口模块630与第二操作系统620的通道，并控制切换模块640不断开解密外设、持续通信状态的外设与本操作系统的通道。
外设接口631通过单端切换器641与第一操作系统610或第二操作系统620连通，外设接口632、633通过多端切换器642与第一操作系统610或第二操作系统620连通，单端切换器641、多端切换器642根据第一操作系统610的控制指令进行切换，如前所述，也可以将第一操作系统610的控制指令通过控制器650下发到单端切换器641、多端切换器642。接口模块630中的外设接口631、632、633均可与第一操作系统610或第二操作系统620连通，但是，单端切换器641仅用于切换外设接口631与第一操作系统610或第二操作系统620间的通道，因此，对于解密外设等可以通过外设接口631与第一操作系统610或第二操作系统620连接，从而对解密外设通道的切换不影响其它外设对通道的选择情况，本实施例在保持接口模块630中的外设接口631、632、633均可与第一操作系统610或第二操作系统620连通的情况下，还减少了单端切换器641及多端切换器642的数量，降低了成本。
图7是本申请又一示例性实施例示出的一种电子设备700的结构示意图；切换模块740包括单端切换器741、742、743，单端切换器741与外设接口731连接，单端切换器742与外设接口732连接，单端切换器743与外设接口733连接，单端切换器741、742、743用于根据第一操作系统710的控制指令切换外设接口730与第一操作系统710或第二操作系统720之间的通道；
第一操作系统710在与接口模块730连通的状态下，检测到接口模块730与第二操作系统720的连接请求时，控制切换模块740连通接口模块730与第二操作系统720的通道，并控制切换模块740不断开解密外设、持续通信状态的外设与本操作系统的通道。
接口模块730中的每一个外设接口731、732、733都配置有一个单端切换器741、742、743，每一个单端切换器741、742、743均可与第一操作系统710或第二操作系统720连通，单端切换器741、742、743根据第一操作系统710的控制指令进行切换，如前所述，也可以将第一操作系统710的控制指令通过控制器750下发到单端切换器741、742、743。本实施例中每一个外设接口731、732、733均可独立的与第一操作系统710或第二操作系统720连通，提高了接口模块730中各外设接口731、732、733的使用灵活性。
