最后,相对水平角计算单元,再将定点水平角与基准水平角相减,而获得相对水平角。
其中,转动角转换单元依据定点倾斜角定点转动角之几何关系,以及基准倾斜角等于基准转动角之关系,将基准倾斜角转换为基准转动角,定点倾斜角换为定点转动角。

请参阅图1,其系为本发明之角度计算系统示意图,如图所示,本发明之角度计算系统包含基准装置1、定点装置2、终端装置3及中间设备4,其中基准装置1仅有一个,而定点装置2有二个,基准装置1及各定点装置2皆透过中间设备4与终端装置3联机。
其中,基准装置1侦测基准点的惯性,而获得基准数据101,并传送至终端装置3。
其中,各定点装置2分别侦测各定点的惯性,而获得定点数据201,并传送至终端装置3。

当基准装置1及定点装置2分别透过中间设备4将基准数据11及定点数据201传送至终端装置3时,接收单元31接收基准数据101及定点数据201,并传送至处理模块32,再由处理模块32利用倾角换算单元321,获得定点倾斜角9及基准倾斜角13。
当使用者欲获得定点与基准点之间的相对水平角16时,水平角转换单元322先将定点倾斜角9转换为定点水平角6,以及将基准倾斜角13转换为基准水 平角14,再由相对水平角计算单元323将定点水平角6相减于基准水平角14而获得定点与基准点之间的相对水平角16。
当使用者欲获得定点与基准点之间的相对转动角17时,转动角转换单元324先将定点倾斜角9换算为定点转动角12,且将基准倾斜角13转换为基准转动角15,再由相对转动角计算单元325将定点转动角12相减于基准转动角15而获得定点与基准点之间的相对转动角17。

获得该轴向7的定点倾斜角9,其中g 0代表标准重力10、θ axis代表该轴向7的定点倾斜角9、A axis代表该轴向7的定点加速度11。
其中,转动角转换单元324再依据原水平轴8与标准重力10的方向互为垂直的关系,推知定点倾斜角9相等于定点转动角12,进而获得定点转动角12。

请参阅图7,其系为本发明之第一实施例的示意图,如图所示,在沿山坡建造之建筑,或特殊的室内设计等场景中,常有一楼平面非为水平的斜坡阶梯,其可利用本发明之角度计算系统,以一楼平面为基准点100,一楼阶梯为第一定点200a,二楼阶梯为第二定点200b,并将基准装置1放置于基准点100,第一定点装置2a放置于第一定点200a,第二定点装置2b放置于第二定点200b, 再由中间设备4收集基准装置1测得之基准数据101、第一定点装置2a测得之定点数据及第二定点装置2b测得之定点数据后,传送至终端装置3。
终端装置3经过倾角换算单元及水平角转换单元的分析后,得到基准水平角、第一定点水平角、第二定点水平角,再藉由相对水平角计算单元求得基准点100与第一定点200a之间的第一相对水平角,以及基准点100与第二定点200b之间的第二相对水平角,其中:
第一相对水平角=第一定点水平角-基准水平角;
第二相对水平角=第二定点水平角-基准水平角。
藉由第一相对水平角及第二相对水平角,建筑师及土木工程技师可以对阶梯进行调整,或其他工程施工之变形量检测。
请参阅图8,其系为本发明之第二实施例的示意图,如图所示,本发明之角度计算系统适用于检测机器手臂18良率的应用场景,其中机器手臂18共有三个转轴181,分别为第一转轴181a、第二转轴181b、第三转轴181c,且基准装置1放置于第一转轴181a,第一定点装置2a放置于第二转轴181b,第二定点装置2b放置于第三转轴181c。
在第二实施例中,当第一转轴18a转动时,第二转轴18b及第三转轴18c亦随之转动,而位于各转轴18上的基准装置1、第一定点装置2a及第二定点装置2b,以及位于目标桌面19上的第三定点装置2c则会侦测惯性而产生基准数据及定点数据,并直接传送至终端装置3,再计算出在第二转轴18b之各轴向的定点转动角与基准转动角之间的相对转动角,第三转轴18c之各轴向的定点转动角与基准转动角之间的相对转动角,以及目标桌面19与夹爪182之间的相对水平角。
藉由了解第二转轴181b的相对转动角,以及第三转轴181c的相对转动角,检测机器手臂良率的品检人员,可以了解机械手臂在各转轴181之间的转动角误差,进而调整角机械手臂18。
除此之外,本发明之角度计算系统还可以应用于桥梁的水平实时检测,例如在桥梁的二端分别放置基准装置及定点装置,持续监测桥梁二端的相对水平角,有利于即早发现桥梁因台风或其他风灾所造成之损坏,达到预防胜于治疗的效果。
另一方面,在实际应用时,还可以爪182上放置水平基准装置1h,且在目标桌面19上放置水平定点装置2h,藉以量测机器手臂18的夹爪182与目标桌面19之间的水平关系。
本发明亦可应用于半导体制造领域,其中当晶圆片在各机台之间传递时,设备工程师可将基准装置放置于目标机台上,并将定点装置放在终端效应器的夹抓上,藉以确保夹抓与目标机台之间的相对水平角,以避免晶圆在转移过程中因水平误差而有破损之情形。

其中,本发明之定点装置及基准装置为加速度仪、陀螺仪或二者以上之组合。
其中,本发明之中间设备为无线存取点(Wireless Access Point)。
其中,本发明之中间设备为非必要组件,本发明之终端装置亦可利用接收单元直接与定点装置及基准装置联机。
综上所述,本发明利用定点装置、终端装置及执行角度计算方法的处理模块之搭配,达到测量遥远二端水平角及转动角之目的,且本发明之定点装置及基准装置体积轻小,仅有一个铜板般的体积,方便工程师们携带,亦可长期安装于被待测物上,而不会造成待测物的负担,以达到实时监控水平角及转动角之目的。
以上仅为本发明之较佳实施例,并非用来限定本发明之实施范围;如果不脱离本发明之精神和范围,对本发明进行修改或者等同替换,均应涵盖在本发明申请专利范围的保护范围当中。
