Description

一种计算机的回控系统及方法 技术领域
本发明涉及信息传输领域，尤其涉及一种计算机的回控系统及方法。
背景技术
在很多应用场景中，例如，在开远程会议时，常常需要用户对远端的计算机进行回控。在现有技术中，结合图1所示的计算机的回控系统，鼠标、显示屏、触控屏等外接HID(Human Interface Device，用户接口装置)装置通过USB接到一无线收发盒子上，当用户通过鼠标或触控屏输入控制信息时，该无线收发盒子便可通过USB获取到该控制信息，并对所接收的USB数据包进行解析，以获取鼠标或触控屏的坐标及动作信息，然后，该无线收发盒子再将解析出的坐标及动作信息通过网络传输至远端的PC(计算机)。PC上安装有应用软件，该应用软件通过OS(Operating System，操作系统)提供的API(Application Program Interface，应用软件接口)来实现以下两个功能：1.根据坐标及动作信息来仿真鼠标或触控屏的动作，即，回控功能；2.将PC当前显示的界面通过该无线收发盒子传输至显示屏或触控屏，即，镜像功能，从而实现用户对远端的PC进行回控。
但是，上述计算机的回控系统具有以下缺陷：
1.必须在PC上安装应用软件，而且，由于每台PC上的OS类型/版本并不完全相同，就需要针对不同的OS类型/版本开发不同的应用软件；
2.用户对PC的回控严重依赖于应用软件的功能，这样，有可能发生部分动作无法仿真的情况。例如，用户可对鼠标的左键、右键以及中间滚轮进行操作，但是，所安装的应用软件在对OS的API参数进行设定时，只做了左键、右键操作的参数设定，而没去做中间滚轮操作的参数设定，所以，用户对中间滚轮的操作就无法实现动作仿真；
3.控制信息需要经过无线收发盒子的处理及PC上应用软件的处理，在回控的实时性上较不佳。
发明内容
本发明要解决的技术问题在于，针对现有技术中上述缺陷，提供一种计算机的回控系统及方法。
本发明解决其技术问题所采用的技术方案是：构造一种计算机的回控系统，用于实现用户通过HID装置对远端的计算机进行回控，包括第一通讯装置及至少一个第二通讯装置，而且，

第四接口，用于从所述计算机接收当前显示的界面信息。
优选地，所述第一接口和所述第三接口分别为USB接口。

本发明还构造一种计算机的回控方法，用于实现用户通过HID装置对远端的计算机进行回控，第一通讯装置进行以下步骤：
与第二通讯装置进行配对联机；
从HID装置接收用户输入的控制信息，并将所述控制信息发送至第二通讯装置；
从第二通讯装置接收当前显示的界面信息，并将所述界面信息发送至HID装置。
优选地，从HID装置接收用户输入的控制信息，包括：
通过USB从HID装置接收用户输入的控制信息。
优选地，将所述界面信息发送至HID装置，包括：
通过HDMI将所述界面信息发送至HID装置。
本发明还构造一种计算机的回控方法，用于实现用户通过HID装置对远端的计算机进行回控，第二通讯装置进行以下步骤：
与第一通讯装置进行配对联机；
从第一通讯装置接收用户输入的控制信息，并将所述控制信息发送至计算机；
从计算机接收当前显示的界面信息，并将所述界面信息发送至第一通讯装置。
优选地，将所述控制信息发送至计算机，包括：
通过USB将所述控制信息发送至计算机。
优选地，从计算机接收当前显示的界面信息，包括：
通过HDMI从计算机接收当前显示的界面信息。
优选地，与第一通讯装置进行配对联机，包括：
接收配对文档，所述配对文档包括第一通讯装置的SSID；
进行WIFI扫描，并将扫描结果与所述配对文档中的SSID进行匹配；
若匹配成功，则接入所述第一通讯装置的AP，以完成配对联机。
优选地，所述配对文档还包括第一通讯装置的标识信息和/或密码信息，而且，所述接入所述第一通讯装置的AP包括：

若匹配成功，则接入所述第一通讯装置的AP。
优选地，与第一通讯装置进行配对联机，包括：
通过蓝牙与第一通讯装置进行配对联机。
实施本发明的技术方案，具有以下有益效果：
1.无需在计算机上安装任何应用软件，真正做到了即插即用；
2.由于是将原始HID装置收到的控制信息原封不动地转送到计算机上，所以，所有的动作信息都可仿真出，并不会出现部分动作无法仿真的情况；
3.控制信息未经过处理，直接将从HID装置获取到的原始数据送进计算机的操作系统，回控的即时性有大幅改善。

图4是本发明计算机的回控方法实施例二的流程图。
具体实施方式
下面将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。基于本发明中的实施例，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，都属于本发明保护的范围。
图1是本发明计算机的回控系统与HID装置、计算机实施例一的结构图，在该实施例中，回控系统10用于实现用户通过HID装置20对远端的计算机30进行回控，而且，回控系统10包括第一通讯装置11及第二通讯装置12，应理解，在其它实施例中，第二通讯装置12的数量可为多个。
结合图2，第一通讯装置11包括第一接口111、第二接口112和第一无线收发模块113，第二通讯装置12包括第三接口121、第四接口122和第二无线收发模块123。而且，第一接口111用于从HID装置20接收用户输入的控制信息，所述控制信息例如包括鼠标的左键点击、右键点击、滚轮滚动等操作信息，或者，包括触控板上的点击、滑动、长按等操作信息；第二接口112用于向HID装置20发送界面信息；第一无线收发模块113用于发送所述控制信息及接收所述界面信息。第三接口121用于将所述控制信息发送至计算机30；第四接口122用于从计算机30接收当前显示的界面信息；第二无线 收发模块123用于在与第一通讯装置11配对联机后，从第一无线收发模块113接收所述控制信息，及向第一无线收发模块113发送所述界面信息。在此需说明的是，当HID装置20为触控屏时，第一通讯装置11的第一接口111、第二接口112均与该触控屏连接；当HID装置20包括鼠标和显示屏时，第一通讯装置11的第一接口111与该鼠标连接，第一通讯装置11的第二接口112与该显示屏连接。
在使用该实施例的计算机回控系统时，首先，将HID装置20通过第一接口111、第二接口112接到第一通讯装置11上，及将第二通讯装置12通过第三接口121和第四接口122接到计算机30上。当第一通讯装置11与第二通讯装置12进行联机配对后，用户可通过HID装置20输入控制信息，然后，第一通讯装置11则可通过第一接口111接收到该控制信息，然后通过网络将该控制信息原封不动地发送至第二通讯装置12，第二通讯装置12再将该控制信息通过第三接口121输入到计算机30的OS，从而触发回控功能。与此同时，计算机30上当前所显示的界面信息也会通过第四接口122传输至第二通讯装置12上，第二通讯装置12接收到该界面信息后，通过网络将该界面信息发送至第一通讯装置11，然后，第一通讯装置11再通过第二接口112将该界面信息发送至HID装置20上进行显示，以实现镜像功能。也就是说，在实现回控功能时，由于控制信息在整个传输过程中未进行任何处理，所以计算机30在从第二通讯装置12接收到控制信息后，会认为第二通讯装置12是一个跟接在第一通讯装置11上的HID装置20一样的HID装置。
实施该实施例的技术方案，具有以下有益效果：
1.无需在计算机30上安装任何应用软件，真正做到了即插即用；
2.由于是将原始HID装置20收到的控制信息原封不动地转送到计算机30 上，所以，所有的动作信息都可仿真出，并不会出现部分动作无法仿真的情况；
3.控制信息未经过处理，直接将从HID装置20获取到的原始数据送进计算机30的操作系统，回控的即时性有大幅改善。
在一个优选实施例中，第一接口111和第三接口121分别为USB接口。
在一个优选实施例中，第二接口112和第四接口122分别为HDMI接口。
图3是本发明计算机的回控方法实施例一的流程图，该实施例的回控方法用于实现用户通过HID装置对远端的计算机进行回控，而且，需说明的是，第一通讯装置和第二通讯装置成对出现，或者，第一通讯装置与第二通讯装置是一对多的关系。第一通讯装置设置在用户侧，第二通讯装置设置在计算机侧，该实施例的回控方法应用在第一通讯装置中，且具体包括以下步骤：
S11.与第二通讯装置进行配对联机；
S12.从HID装置接收用户输入的控制信息，并将所述控制信息发送至第二通讯装置；
S13.从第二通讯装置接收当前显示的界面信息，并将所述界面信息发送至HID装置。在此需说明的是，步骤S12和步骤S13并无明显时序关系，可同时执行。
在该实施例中，当第一通讯装置与第二通讯装置联机配对后，用户可通过HID装置输入控制信息，第一通讯装置便可接收到该控制信息，然后通过网络将该控制信息原封不动地发送至第二通讯装置。第二通讯装置再将该控制信息发送到计算机的OS，从而触发回控功能。与此同时，计算机上当前所显示的界面信息也会传输至第二通讯装置上，第二通讯装置接收到该界面信息后，通过网络将该界面信息发送至第一通讯装置，然后，第一通讯装置再 将该界面信息发送至HID装置上进行显示，以实现镜像功能。也就是说，在实现回控功能时，由于控制信息在整个传输过程中未进行任何处理，所以计算机在从第二通讯装置接收到控制信息后，会认为第二通讯装置是一个跟接在第一通讯装置上的HID装置一样的HID装置。
实施该实施例的技术方案，具有以下有益效果：
1.无需在计算机上安装任何应用软件，真正做到了即插即用；
2.由于是将原始HID装置收到的控制信息原封不动地转送到计算机上，所以，所有的动作信息都可仿真出，并不会出现部分动作无法仿真的情况；
3.控制信息未经过处理，直接将从HID装置获取到的原始数据送进计算机的操作系统，回控的即时性有大幅改善。
优选地，在步骤S12中，通过USB从HID装置接收用户输入的控制信息；在步骤S13中，通过HDMI将所述界面信息发送至HID装置。
图4是本发明计算机的回控方法实施例二的流程图，该实施例的回控方法用于实现用户通过HID装置对远端的计算机进行回控，而且，需说明的是，第一通讯装置和第二通讯装置成对出现，或者，第一通讯装置与第二通讯装置是一对多的关系。第一通讯装置设置在用户侧，第二通讯装置设置在计算机侧，该实施例的回控方法应用在第二通讯装置中，且具体包括以下步骤：
S21.与第一通讯装置进行配对联机；
S22.从第一通讯装置接收用户输入的控制信息，并将所述控制信息发送至计算机；
S23.从计算机接收当前显示的界面信息，并将所述界面信息发送至第一通讯装置。在此需说明的是，步骤S22和步骤S23并无明显时序关系，可同时执行。
在该实施例中，当第二通讯装置与第一通讯装置联机配对后，用户可通过HID装置输入控制信息，第一通讯装置便可接收到该控制信息，然后通过网络将该控制信息原封不动地发送至第二通讯装置。第二通讯装置再将该控制信息发送到计算机的OS，从而触发回控功能。与此同时，计算机上当前所显示的界面信息也会传输至第二通讯装置上，第二通讯装置接收到该界面信息后，通过网络将该界面信息发送至第一通讯装置，然后，第一通讯装置再将该界面信息发送至HID装置上进行显示，以实现镜像功能。也就是说，在实现回控功能时，由于控制信息在整个传输过程中未进行任何处理，所以计算机在从第二通讯装置接收到控制信息后，会认为第二通讯装置是一个跟接在第一通讯装置上的HID装置一样的HID装置。
实施该实施例的技术方案，具有以下有益效果：
1.无需在计算机上安装任何应用软件，真正做到了即插即用；
2.由于是将原始HID装置收到的控制信息原封不动地转送到计算机上，所以，所有的动作信息都可仿真出，并不会出现部分动作无法仿真的情况；
3.控制信息未经过处理，直接将从HID装置获取到的原始数据送进计算机的操作系统，回控的即时性有大幅改善。
优选地，在步骤S22中，通过USB将所述控制信息发送至计算机；在步骤S23中，通过HDMI从计算机接收当前显示的界面信息。
在一个可选实施例中，步骤S21可包括以下步骤：
接收配对文档，所述配对文档包括第一通讯装置的SSID；
进行WIFI扫描，并将扫描结果与所述配对文档中的SSID进行匹配；
若匹配成功，则接入所述第一通讯装置的AP，以完成配对联机。
在该实施例中，第二通讯装置通过接收配对文档来获取第一通讯装置的 SSID信息。而且，在启动时，会做WIFI扫描，将扫描结果与配对文档中的SSID做比对，如果匹配成功，则接入第一通讯装置的AP，以完成配对。
进一步地，配对文档还包括第一通讯装置的标识信息和/或密码信息，在SSID匹配成功时，还根据扫描结果判断配对文档中的标识信息和/或密码信息是否匹配，只有在标识信息和/或密码信息匹配成功时，才接入第一通讯装置的AP。
在一个具体例子中，可通过USB线缆接收配对文档。具体为：将第二通讯装置上的USB线缆直接接上第一通讯装置的USB端口。第一通讯装置在通电后，会先判断接上来的USB装置是否为第二通讯装置，若是，会将一份配对文档复制到所连接的第二通讯装置中，配对文档里面包括有第一通讯装置的设备信息，具体为：类别、uuid(唯一标识符)、设备名称、SSID、无线加密机制、加密后的联机密码等。第二通讯装置凭着这份配对文档，在启动的时候通过无线网络去寻找附近是否有相同配对文档的第一通讯装置，从而完成第一通讯装置与第二通讯装置的配对。而且，当第二通讯装置上的指示灯或第一通讯装置的OSD画面上所显示的“Pairing”转为OK，即代表配对完成。
在一个具体例子中，还可通过终端设备接收配对文档。具体为：首先说明的是，第一通讯装置的嵌入式网页具有配对文档下载的功能，第二通讯装置的嵌入式网页具有配对文档上传的功能。当需要配对时，通过操控终端设备从第一通讯装置上下载该配对文档，然后，将第二通讯装置的AP开启，通过终端设备连上第二通讯装置的AP，开启第二通讯装置的嵌入式网页，进入配对文档上传界面，点选上传控件(upload)，从而上传事先下载好的配对文档。
在一个具体例子中，还可通过U盘接收配对文档。具体地：将U盘插入第一通讯装置，并按下功能键，此时，第一通讯装置中预先存储的配对文档会复制到U盘中。然后，再将U盘插入第二通讯装置，并将第二通讯装置设置为从设备，此时，U盘中存储的配对文档也会复制到第二通讯装置中。当配对完成时，第一通讯装置的指示灯会变成白色。
在一个具体例子中，还可通过U盘接收配对文档。具体地：将U盘插入终端设备(例如PC)的USB接口，当PC与第一通讯装置连接后，可通过第一通讯装置的嵌入式网页来将配对文档下载到U盘中。然后，将该U盘插入第二通讯装置，此时，第二通讯装置便会从U盘中下载该配对文档，从而完成配对。
当然，在其它实施例中，还可通过以下方式在进行配对：首先，第二通讯装置内也包括嵌入式网页。在配对时，用户可将该第二通讯装置通过以太网络或者无线网络连上其它的终端设备(例如PC、智能手机、PAD等)，并通过终端设备在第二通讯装置中输入第一通讯装置的SSID，必要时再输入密码，从而将第二通讯装置接入第一通讯装置的AP，以完成配对。
以上几个实施例都是通过WIFI进行配对，在另一些实施例中，还可通过蓝牙进行配对。具体地：按下第一通讯装置上的配对按键并进入蓝牙配对模式，再按下第二通讯装置上的主+侧按键并进入配对模式，然后，第二通讯装置会扫描周围附近的第一通讯装置，从而进行蓝牙连接。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何纂改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
