需要说明的是，电容感应层只有在接收到控制指令时，才产生电容感应值。在未接收到控制指令时，只存在对地电容的电容值。当接收到控制指令时，电容感应层与进行控制操作的控制物体之间形成一个控制电容，该控制电容与电容感应层的对地电容并联，因此，电容感应层产生的感应电容值为该控制电容的电容值与对地电容的电容值的和。其中，该控制物体可以是人体、导体或非导体的机械物件。
还需要说明的是，在未接收到控制指令，且缓冲层未发生形变时，电容感应层与基板之间的极间电容的电容值为初始电容值，当缓冲层发生形变后，初始电容值增大，产生与所述控制指令对应的极间电容值。
应用本发明实施例提供的系统，根据按键外壳、电容感应层、缓冲层和基板的组成结构，在终端按键接收到控制指令时，产生与所述控制指令对应的感 应电容值和极间电容值，以通过检测芯片对感应电容值和极间电容值的检测，确定终端按键所受到的控制类型，有效的避免终端按键因为误触碰而导致的误操作，提高用户体验感。
本发明实施例提供的终端控制系统中，上述系统中的检测芯片100的内部组成结构，如图3所示，具体包括：
第一检测模块110、第二检测模块120和触发模块130；
所述第一检测模块，用于检测所述电容感应层的对地电容，当所述电容感应层产生感应电容值时，检测与所述感应电容值对应的感应电容变化量，并确定所述感应电容变化量是否大于预先设置的第一阈值；
所述第二检测模块，用于检测所述电容感应层与所述基板之间的极间电容，当所述电容感应层与所述基板之间产生大于初始电容值的极间电容值时，检测与所述极间电容值对应的极间电容变化量，并确定所述极间电容变化量是否大于预先设置的第二阈值；
所述触发模块，用于当所述感应电容变化量大于预先设置的第一阈值，且所述极间电容变化量大于预先设置的第二阈值时，确定所述控制指令对应的控制类型为用户按压控制，并触发所述终端设备执行与所述用户按压控制对应的按压控制操作；当所述感应电容变化量不大于所述第一阈值，且所述极间电容变化量大于所述第二阈值时，确定所述控制指令对应的控制类型为机械按压控制，不触发所述终端设备执行任何的控制操作；当所述感应电容变化量大于所述第一阈值，且所述极间电容变化量不大于所述第二阈值时，确定所述控制指令对应的控制类型为用户触摸控制，并触发所述终端设备执行与所述用户触摸控制对应的触摸控制操作；当所述感应电容变化量不大于所述第一阈值，且所述极间电容变化量不大于所述第二阈值时，确定所述控制指令对应的控制类型为机械触摸控制，不触发所述终端设备执行任何控制操作。
在本发明实施例提供的终端控制系统中，如图3所示的检测芯片中具体包括了第一检测模块、第二检测模块和触发模块。其中，第一检测模块与终端按键中的电容感应层连接，用于检测电容感应层的对地电容的电容值C1。当终端按键接收到外部的控制指令时，电容感应层将产生感应电容值C1'，并检测出该感应电容值C1'，根据该感应电容值，确定电容感应层的感应电容变化量 ΔC1，其中ΔC1＝C1'-C1。并确定感应电容变化量是否大于预先设置的第一阈值ΔC a。该第一阈值的设置方式，可以根据用户的人体介电常数与各个机械设备的介电常数之间的区别进行设置，由于人体介电常数远大于各个机械设备的介电常数，因此利用介电常数之间的差别设置第一阈值，以区分终端按键是用户进行控制操作还是机械的误触碰。
第二检测模块分别与终端按键中的电容感应层和基板连接，用于检测电容感应层与基板之间的极间电容的初始电容值C2，当缓冲层发生形变，使得极间间距变小时，极间电容将增大，产生与该形变对应的极间电容值时，由第二检测模块检测出产生的与该形变对应的极间电容值C2'，确定极间电容变化量ΔC2，其中，ΔC2＝C2'-C2。并确定该极间电容变化量是否大于预先设置的第二阈值ΔC b。其中，第二阈值的设置方式根据极间间距进行设置，当电容感应层发生形变时，极间间距发生改变，根据极间间距的变化程度，可以确定终端按键是受到触摸控制还是按压控制。当终端按键受到的是按压控制时，电容感应层变形明显，极间间距变小，极间电容变大。当终端按键受到的是触摸控制时，电容感应层变形不明显，极间间距基本不变，极间电容的变化也不明显，因此当极间间距变小到一定程度时，极间电容明显增大，因此极间电容变化量也将大于第二阈值。
触发模块分别与第一检测模块和第二检测模块连接，经由第一检测模块和第二检测模块确定感应电容变化量和极间电容变化量后，根据感应电容变化量和极间电容变化量，触发终端设置执行相对应的控制操作。当感应电容变化量大于第一阈值，即ΔC1＞ΔC a，且极间电容变化量大于第二阈值，即ΔC2＞ΔC b时，确定控制指令对应的控制类型为用户按压控制，并由检测芯片中的触发模块触发终端设备执行与用户按压控制对应的按压控制操作；当感应电容变化量不大于第一阈值，即ΔC1≤ΔC a，且所述极间电容变化量大于第二阈值，即ΔC2＞ΔC b时，确定控制指令对应的控制类型为机械按压控制，触发模块将不触发终端设备执行任何的控制操作；当感应电容变化量大于第一阈值，即ΔC1＞ΔC a，且极间电容变化量不大于第二阈值，即ΔC2≤ΔC b时，确定控制指令对应的控制类型为用户触摸控制，触发模块触发终端设备执行与用户触摸控制对应的触摸控制操作；当感应电容变化量不大于第一阈值，即ΔC1≤ΔC a，且极间电容变化量不 大于第二阈值，即ΔC2≤ΔC b时，确定控制指令对应的控制类型为机械触摸控制，触发模块不触发终端设备执行任何控制操作。
可选的，第二检测模块除了可以检测极间电容值之外，可以用于检测终端按键所受到的压力值。当终端按键接收到外部的控制指令时，可通过检测终端按键中电容感应层和基板所受到的压力值变化量，确定该控制指令是不是为按压控制。当压力值变化量大于预先设置的压力阈值时，则确定终端按键受到按压控制。再结合确定感应电容变化量，以确定终端按键接收到的控制指令的控制类型为用户按压控制还是机械按压控制。
应用本发明实施例提供的终端控制系统中，由检测芯片中的第一检测模块、第二检测模块和触发模块，检测终端按键接收到控制指令时，确定与该控制指令对应的控制类型，并触发终端设备执行与该控制类型对应的控制操作，以防止终端设备由于终端按键的控制指令进行误操作，提高用户的体验感。
本发明实施例提供的终端控制系统中，检测芯片与终端按键连接时，可以实时检测终端按键中的感应电容值和极间电容值，并根据感应电容变化量和极间电容变化量确认终端按键的控制类型，以使检测芯片触发终端设备执行相对应的控制操作。为了使终端按键实现的功能更加丰富，本发明实施例还可以包括：

本发明实施例提供的终端控制系统中，方向感应传感器是检测终端设备的屏幕方向的传感器，该方向感应传感器与检测芯片连接，设置于终端设备内的任意一处，可以设置于靠近该检测芯片的一侧。该方向感应传感器用于感应终端设备的屏幕方向。当终端设备的屏幕方向发生改变，例如终端设备的屏幕方向原先为竖屏，后切换为横屏时，方向感应传感器则根据终端屏幕改变的方向，向检测芯片发送切换指令。当检测芯片在接收到方向感应传感器发送的方向切 换指令后，切换终端按键的按键功能。当终端按键在终端设备的屏幕方向已经发生改变的情况下，接收到外部的控制指令，并且由检测芯片检测出与该控制指令对应的控制类型时，则检测芯片可以根据终端按键的按键功能，触发终端设备执行与控制操作对应的按键功能。
在本发明实施例提供的系统中，可以应用于多种终端设备，例如智能手机、平板电脑等。当终端设备为智能手机时，进行以下举例说明：
智能手机的一侧设置第一按键。当用户使用智能手机听音乐时，第一按键在竖屏状态下用于实现智能手机增加音量以及向上翻页的功能。当用户按压第一按键可以增加音量，当用户触摸滑动第一按键时，可以向上翻页。当智能手机的第一按键在竖屏状态下接收到外部的控制指令时，第一按键中的电容感应层产生感应电容值，基板和电容感应层之间产生极间电容值，并由智能手机内部的检测芯片检测感应电容值和极间电容值，确定感应电容变化量和极间电容变化量。当感应电容变化量大于预先设置的第一阈值，且极间电容变化量大于预先设置的第二阈值时，则检测芯片确定该控制指令对应的控制类型为用户按压控制，并触发智能手机根据用户按压控制增大音量。当用户切换智能手机的屏幕状态，并使用智能手机进行射击类游戏时，由方向感应传感器确定智能手机的屏幕方向，并向检测芯片发送方向切换指令。检测芯片在接收到方向感应传感器发送的方向切换指令后，切换第一按键的按键功能。例如第一按键在横屏状态下用于实现射击游戏中的人物前移和开镜功能。若用户按压第一按键时可以使游戏中的人物前移，当用户触摸滑动第一按键时可以开镜。当智能手机的第一按键在横屏状态下接收到外部的控制指令时，产生感应电容值和极间电容值，并智能手机内部的检测芯片检测感应电容值和极间电容值，确定感应电容变化量和极间电容变化量。当感应电容变化量不大于第一阈值，且极间电容变化量大于第二阈值时，则检测芯片确定该控制指令对应的控制类型为机械按压控制，检测芯片将不触发智能手机进行射击游戏中的开镜功能。
需要说明的是，方向感应传感器可以是重力加速度传感器Gsensor或陀螺仪等其他可感应终端屏幕的方向发生变化的传感器。
可选的，当方向感应传感器在检测到终端设备的屏幕方向发生改变时，也可以向检测芯片发送方向切换指令，使检测芯片关闭终端按键的部分功能。
应用本发明实施例提供的系统中，所述检测芯片可与方向感应传感器进行连接，使终端按键的功能更加丰富，提高了用户的体验感。

各个所述按键外壳按预设的排布方式分别设置在所述终端控制系统的侧表面。
本发明实施例提供的系统中，终端控制系统的侧面可以设置至少一个终端按键，其中终端按键的按键外壳可以设置于侧表面。每个终端按键电容感应层、缓冲层和基板均设置在终端控制系统的内部。且每一个按键外壳均按键预先设置的排布方式设置在终端控制系统的侧表面。例如，该终端控制系统一侧设置的终端按键，全都是可以实现按压控制操作，另一侧都可以实现触摸控制操作。或，该终端控制系统一侧设置的终端按键，均可实现按压控制操作和触摸控制操作，另一侧不设置终端按键等。
本发明提供的终端控制系统中，电容感应层可以为单个条形结构，也可以为设置有至少两个通道以上的滑动条形结构。具体如图4所示。如图4中的图(a)为单个条形结构，当电容感应层为单个条形结构时，主要实现终端按键的按压功能，用户可通过按压所述终端按键，实现终端按键的按键功能。如图4中的图(b)和图(c)，其中图(b)为两个通道的滑动条形结构，图(c)为四个通道的滑动条形结构，当电容感应层为至少两个通道以上的滑动条形结构时，可以实现终端按键的按压或触摸控制操作的功能，用户可以通过按压终端按键或轻触滑动终端按键，实现终端按键的按压控制操作的功能或触摸控制操作的功能。其中，当电容感应层为滑动条形结构时，每一个通道中可以设置一个电容器，用于感应用户触摸终端按键进行滑动操作时，用户滑动终端按键的速度，也可以通过电容感应层上的用户触摸终端按键的滑动速度，确定用户控制类型是按压、轻触还是滑动触摸，以根据不同的控制类型实现不同的控制操作。电容感应层上的通道越多，设置的电容器就越多，对用户滑动终端按键的速度的感应越灵敏。缓冲层位于电容感应层和基板之间，该缓冲层可以是泡 棉或弹簧等其他弹性结构的材料组成的支撑电容感应层的空气间隙层。基板可以是终端设备内部的接地金属。
应用本发明实施例的系统，终端按键的按键外壳、电容感应层、缓冲层与基板的设置方式可以使用户更加便捷的进行操作，提高用户体验感。
与图1所述的系统相对应，本发明实施例提供了一种终端控制方法，用于对所述终端控制系统中各个系统结构的具体实现，本发明实施例提供的终端控制方法可以应用计算机终端或各种移动设备中，其执行主体可以为检测芯片，该方法的方法流程图如图5所示，具体包括：
S501：检测预先设置的终端按键在接收到控制指令时所产生的与所述控制指令对应的感应电容值和极间电容值；
本发明实施例提供的方法中，检测芯片实时检测终端按键的产生的电容值，当终端按键在接收到控制指令时，将产生与所述控制指令对应的感应电容值和极间电容值。检测芯片对终端按键产生的感应电容值和极间电容值进行检测。
S502：依据所述感应电容值和所述极间电容值，确定与所述感应电容值对应的感应电容变化量和与所述极间电容值对应的极间电容变化量；
本发明实施例提供的方法中，当检测芯片检测到终端按键对感应电容值和极间电容值时，根据感应电容值和极间电容值，确定终端按键上的感应电容变化量和极间电容变化量。
需要说明的是，在未接收到控制指令时，检测芯片智能检测到终端按键中的对地电容的电容值和极间电容的初始电容值。例如，终端按键在未接收到控制指令时对地电容的电容值为C1，极间电容的初始电容值为C2；在接收到控制指令后，产生与该控制指令对应的感应电容值C1'和极间电容值C2'。则终端按键上感应电容变化量为ΔC1＝C1'-C1，极间电容变化量为ΔC2＝C2'-C2。
S502：依据所述感应电容变化量和所述极间电容变化量确定与所述控制指令对应的控制类型，并触发终端设备执行与所述控制类型对应的控制操作。
本发明实施例提供的方法中，根据感应电容变化量和极间电容变化量，可确定接收到的控制指令对应的控制类型。检测芯片根据控制类型，触发终端设 备根据终端按键的按键功能，执行与该控制类型相对应的控制操作。
需说明的是，控制类型包括用户控制和机械控制；当用户对终端按键进行触摸滑动或按压时，都属于用户控制；当并非用户对终端按键进行触摸滑动或按压时，属于机械控制。
本发明实施例提供的方法中，当所述终端按键接收到外部的控制指令时，检测芯片将根据终端按键在接收到控制指令时，检测由终端按键产生与该控制指令对应的的感应电容值C1'和极间电容值C2'。并根据感应电容值确定感应电容变化量ΔC1，根据极间电容值确定极间电容变化量ΔC2。依据感应电容变化量和极间电容变化量，确定该终端按键接收到的与控制指令对应的控制类型，再根据该控制类型触发该终端按键所在的终端设备，由终端设备执行与该控制类型对应的控制操作。
应用本发明实施例提供的方法，通过调用检测芯片，确定控制指令的类型，使终端设备执行相对应的操作，避免了误操作的情况，提高用户体验感。
本发明实施例提供的方法中，基于上述步骤S503，依据所述感应电容变化量和所述极间电容变化量确定与所述控制指令对应的控制类型，并触发终端设备执行与所述控制类型对应的控制操作，具体包括：
检测所述感应电容变化量是否大于预先设置的第一阈值；
当所述感应电容变化量大于所述第一阈值时，确定与所述控制指令对应的控制类型为用户控制，并触发终端设备执行与所述用户控制对应的控制操作；
当所述感应电容变化量不大于所述第一阈值时，确定与所述控制指令对应的控制类型为机械控制，不触发所述终端设备执行任何的控制操作。
本发明实施例提供的方法中，通过检测感应电容变化量可确定控制指令时用户进行控制操作还是机械进行控制操作。当感应电容变化量大于第一阈值，则为用户进行控制操作，检测芯片可以触发终端设备执行相对应的控制操作。若不大于第一阈值，则不是用户控制操作，检测芯片不会触发终端设备执行任何操作。
本发明实施例提供的终端控制系统中，可以应用在多种领域，例如在智能手机领域中，当智能手机侧键受到外部控制指令时，调用检测芯片检测智能手机侧键中的感应电容值，并确定感应电容变化量是否大于第一电容阈值；当感 应电容变化量大于第一电容阈值时，则确定智能手机侧键收到的控制指令对应的控制类型为用户控制。当确定控制类型为用户控制后，智能手机侧键可触发智能手机根据智能手机侧键的侧键功能，执行与该侧键功能对应的功能操作，提高用户使用智能手机侧键的体验感。
应用本发明实施例提供的方法，通过检测芯片确定控制指令对应的控制类型是否为用户控制，在确定为用户控制后，依据按键功能，触发终端设备执行与按键功能对应的控制操作，提高了用户的体验感。
本发明实施例提供的方法中，基于上述实施例，当所述感应电容变化量大于所述第一阈值时，确定与所述控制指令对应的控制类型为用户控制，并触发终端设备执行与所述用户控制对应的控制操作，具体包括：
当所述感应电容变化量大于所述第一阈值时，检测所述极间电容变化量是否大于预先设置的第二阈值；
当所述极间电容变化量大于所述第二阈值时，确定所述用户控制为用户按压控制，并触发终端设备执行与所述用户按压控制对应的按压控制操作；
当所述极间电容变化量不大于所述第二阈值时，确定所述用户控制为用户触摸控制，并触发终端设备执行与所述用户触摸控制对应的触摸控制操作。
本发明实施例提供的方法中，为了更进一步确定用户控制是否是用户按压控制还是用户触摸控制，检测芯片检测极间电容变化量是否大于第二阈值。若大于，则为用户按压控制，若不大于，则为用户触摸控制。若为用户按压控制时，则触发终端设备执行与按压控制对应的触摸控制操作，若为用户触摸操作，则触发终端设备执行与触摸控制对应的触摸控制操作。即，当终端按键接收到按压或触摸时，可以执行不同的按键功能。
应用本发明实施例提供的方法，可以更进一步确定控制类型，以使终端设备执行更准确的控制操作，提供用户体验感。
基于上述实施例，另一方面，当所述感应电容变化量不大于所述第一阈值时，确定与所述控制指令对应的控制类型为机械控制，不触发所述终端设备执行任何的控制操作，具体包括：
当所述感应电容变化量不大于所述第一阈值时，检测所述极间电容变化量是否大于预先设置的第二阈值；
当所述极间电容变化量大于所述第二阈值时，确定所述机械控制为机械按压控制，不触发所述终端设备执行任何的控制操作；
当所述极间电容变化量不大于所述第二阈值时，确定所述机械控制为机械触摸控制，不触发所述终端设备执行任何的控制操作。
本发明实施例提供的方法中，在确定控制类型为机械控制后，可以进一步确定是机械按压控制还是机械触摸控制。当检测到极间电容变化量大于第二阈值，则确定是机械按压控制，若极间电容变化量不大于第二阈值，则确定是机械触摸控制。但无论是机械按压还是触摸，都不会触发终端设备执行任何操作。
应用本发明实施例提供的方法，当控制类型为机械按压控制或机械触摸控制时，将不会触发终端设备执行任何的控制操作，防止因为机械触碰导致的误操作，提高了用户的体验感。
基于上述实施例提供的方法，有以下具体实现的实施例，所述实施例的实施方法应用于智能手机侧键，具体如图6所述，包括：
S601：智能手机侧键接收到控制指令；
S602：智能手机内设置的检测芯片检测智能手机侧键中产生的与该控制指令对应的感应电容值，并确定感应电容变化量的是否大于预先设置的第一阈值；
S603：当感应电容变化量大于第一阈值时，则确定控制指令对应的控制类型为用户控制，并执行步骤S605；
S604：当感应电容变化量不大于第一阈值时，则确定控制指令对应的控制类型为机械控制，不触发智能手机执行任何的操作；
S605：当确定控制指令对应的控制类型为用户控制时，再检测智能手机侧键中的极间电容变化量是否大于预先设置的第二阈值；
S606：当极间电容变化量大于第二阈值时，则确定用户控制为用户按压控制，触发智能手机，执行与用户按压控制对应的按压控制操作；
S607：当极间电容变化量不大于第二阈值时，则确定用户控制为用户触摸控制，触发智能手机，执行与用户触摸控制对应的触摸控制操作。
可选的，可以先确定极间电容变化量是否大于第二阈值，确定控制指令对应的控制类型为按压控制还是为触摸控制后，再确定感应电容变化量是否大于 第一阈值，确定控制指令对应的控制类型为用户控制还是机械控制。
本发明实施例提供的方法中，检测芯片除了检测终端按键的电容变化量之外，还可以通过检测方向感应传感器，确定终端设备的屏幕改变方向，从而改变终端按键的按键功能，具体还包括：
当接收到预先设置的方向感应传感器发送的方向切换指令时，依据所述方向切换指令，切换所述终端按键的与所述控制操作对应的按键功能，并在确定所述终端按键接收到的控制指令对应的控制类型为用户控制时，触发所述终端设备执行与所述按键功能对应的控制操作。
本发明实施例提供的方法中，当方向感应传感器在感应到终端设备的屏幕方向发生改变时，向检测芯片发送方向切换指令，以提示检测芯片屏幕方向的改变。检测芯片在接收到方向切换指令后，切换终端按键的按键功能。例如原先终端设备的按键功能是增大音量，在接收到切换指令后，则将按键功能切换成翻页。当终端按键接收到控制指令时，若检测芯片检测到控制指令为用户控制时，则根据切换的按键功能，触发终端设备执行与控制指令相对应的控制操作。
可选的，当检测芯片在接收到方向切换指令后，也可以关闭终端按键的按键功能。
