将 B3 中计算出的三角形的参数数据与第二设备预置的图形参数相比 较, 对应到最为相似的参数。 由于误差是不可能避免的, 只有减小误差, 在 本发明实施例中第二设备默认一定的误差范围。 根据对比结果和误差允许范 围, 第二设备判断出该三角形的参数与预置正三角形参数相符, 认为是执行 清洗指令。 如果超出了误差范围, 第二设备不能识别此操作指令, 则返回到 歩骤 B2。
B5、 执行清洗指令。
采用本发明实施例二提供的方法的优点是: 通过第二设备触摸屏接触到 不同的触摸图形, 计算该触摸图形的参数, 根据计算的图形参数, 判断计算 出图形参数是否包含在预置的正三角形参数中, 如果是, 执行相应的操作指 令, 完成机械对机械的控制, 因为图形是多变丰富的, 采用图形作为操作指 令大大的增加了操作指令的数目, 其次, 一个图形只用来执行一个操作指 令, 不会因为执行环境不同而使得所述图形代表的操作命令不同, 操作直接 快速。
实施例三、 一种图形触摸命令的执行方法, 该实施例与实施例二的区别 在于, 本发明实施例二中预置的图形参数包括能代表所述图形形状和大小的 参数, 所述的图形通常为规则图形, 如三角形、 四边形等; 而本发明实施例 三中预置的图形只是用面积参数表示, 面积不同图形代表不同的操作指令, 所述的图形可以为不规则图形, 如手印形状、 雨滴形状等, 也可以是规则图 形。 参见图 3, 包括:
Cl、 第二设备预置图形命令, 将面积为 15至 20平方厘米的图形代表 执行清洗操作的指令。
其中, 本实施例中第二设备的触摸屏要能将预置的图形全部容纳, 同 时, 预置的图形面积不小于第二设备的触摸屏的识别最小图形的面积, 即最 大分辨率分辨的面积。
C2、 第一设备将一个面积为 16平方厘米的触控面板触摸第二设备的触 摸屏, 以使第二设备接触到第一设备的触摸图形后, 获取触摸图形的信息。
第二设备的感应设备需要在最大能力范围内感应出尽量多的边界点, 以 达到精确计算出触摸面积大小的目的。
C3、 第二设备获取第一设备的触摸图形信息, 根据所述触摸图形信息 计算该触摸图形的面积。
其中, 第二设备根据传感设备感应到的所有的边界点的位置信息, 计算 边界点所围成的图形的面积。 如果是规则图形, 则面积容易计算出; 如果是 不规则图形, 用求积分计算出所述图形的面积, 具体计算方法为现有技术, 此处不作限定。
C4、 根据计算出的图形面积, 判断图形面积与歩骤 C1中预置的图形面 积是否相符, 如果是, 执行 C5。 如果 C3 中计算出的图形的面积在预置的 面积命令中不存在, 则第二设备返回歩骤 C2。
由于误差是不可能避免的, 只能减小误差, 在本发明实施例三中第二设 备默认一定的误差范围, 如果计算的面积大小在误差范围内, 也认为是执行 清洗指令。 如果超出了误差范围, 第二设备不能识别此操作指令, 则返回到 歩骤 C2。
C5、 第二设备执行该面积参数代表的操作命令, 本实施例为执行清洗 指令。
采用本发明实施例三提供的方法的优点是: 通过第二设备触摸屏接收到 不同的触摸图形, 计算该触摸形状的面积, 判断图形面积预置的图形面积是 否相符, 如果是, 执行相应的操作命令, 完成机械对机械的控制, 因为图形 面积是丰富的, 采用图形作为操作指令大大的增加了操作指令的数目, 同 时, 一个图形只用来执行一个操作指令, 不会因为执行环境不同而使得所述 图形代表的操作命令不同, 操作直接快速。
通过以上是对本发明实施例二、 三的说明, 显而易见的, 可以将图形的 面积和形状结合起来作为图形的命令, 具体操作过程可以结果实施例二和三 容易得到, 采用这种方法更加丰富了图形命令, 其次, 一个图形只用来执行 一个操作指令, 不会因为执行环境不同而使得所述图形代表的操作命令不 同, 操作直接快速。
以上是对本发明实施例提供的方法的描述, 采用上述方法, 可以得到一 种用机械的方法控制设备的方法, 但是因为在具体操作的过程中, 第二设备 的接触屏在接收触摸图形的同时, 会连同噪声一起接收, 对操作指令的识别 产生影响, 所以在第二设备中增加了过滤噪声功能, 有效去除噪声。 其具体 操作歩骤是在实施例二的歩骤 B2之后、 B3之前, 或在实施例三的歩骤 C2 之后、 C3之前, 添加歩骤 D, 分别参见图 2、 图 3, 包括:
D、 对接收的触摸数据进行分析, 消除认为是噪声的触摸点。
其中, 便于理解可以认为接收到的图形信息中包括一些噪声, 单个或者 不相连的点往往被认为噪声。 可以运行噪声算法去除一些与其它点不相连的 点。 使得计算的参数更准确。
通过对实施例二、 三中的方法中增加过滤掉噪声功能, 计算该触摸图形 参数, 根据计算的图形参数, 判断触摸屏接收到的触摸图形与预置的图形是 否相符, 如果是, 执行触摸图形所代表的操作指令, 完成机械对机械的控 制, 采用图形作为操作指令增加了操作指令的数目。 其次, 一个图形只用来 执行一个操作指令, 不会因为执行环境不同而使得所述图形代表的操作命令 不同, 操作直接快速, 再次, 增加过滤操作使第二设备执行命令更准确。
以上是对本发明实施例提供的方法的描述, 本发明实施例还提供了一种 图形触摸命令的执行装置, 包括:

判断单元 45接收第二获取单元 44中计算出的图形参数, 判断单元 45 将计算出的图形参数与预置单元中预置的图形参数对比, 判断接收到的触摸 图形参数是否包含在预置图形参数中, 如果是, 判断单元 45发送执行触摸 图形所代表的操作指令到执行单元 46, 执行单元 46接收到指令后, 执行触 摸图形所代表的操作指令。 如果否, 执行单元 46不执行任何操作, 装置处 于接收触摸图形的状态。
在实际应用中, 所述的第一获取单元 42还可以细化包括: 触摸屏 10和 传感单元 20。
触摸屏 10, 用于与触摸图形接触;

其中, 传感单元 20将触摸屏 10划分为一定数目的坐标系上的点, 所述 点的数目取决于触摸屏 10的灵敏度和分辨率。 传感单元 20中的坐标位置可 以采用笛卡尔坐标系, 如坐标 X和坐标 Y, 也可以是其它坐标系, 如极坐 标系等。 当触摸信号进入传感单元 20 时, 触摸点被映射为坐标, 以坐标的 形式发送到第二获取单元 44。
