具体实施例
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述。
本申请可以应用于无人飞行器的启动过程,无人飞行器可以是用于任意领域的飞行器。无人飞行器存在不同的工作模式,每种工作模式都对应一个特定螺旋桨状态信息,若在启动时,无人飞行器的当前螺旋桨状态信息不是工作模式对应的特定螺旋桨状态信息,则以该工作模式启动无人飞行器会出现无人飞行器的异常,导致安全隐患。例如,在农业领域中,无人飞行器可以用于向农作物喷洒农药,无人飞行器可以存在两种模式:大田模式和果树模式,其中,大田模式下无人飞行器可以用于向平坦的农作物进行喷洒农药,例如,向小麦、水稻、油菜等喷洒农药,果树模式下无人飞行器可以用于向高低不同的农作物进行喷洒农药,例如,向果树喷洒农药。
如图1所示的大田模式下无人飞行器的螺旋桨状态示意图,无人飞行器主要包括如下部件:机身、螺旋桨、电机、喷杆、喷嘴以及连接部件,如图1所示,螺旋桨设置于电机上,以使电机为螺旋桨提供旋转所需的电能,喷杆连接于电机上,并垂直于机身,喷嘴连接于喷杆上并且喷嘴的朝向垂直于机身,在大田模式下,无人飞行器的螺旋桨通常被设置为与无人飞行器的机身位于同一平面,以使得无人飞行器在水平面上飞行时螺旋桨也与水平面平行,又由于喷嘴的朝向垂直于无人飞行器的机身,即平行于螺旋桨,从而喷嘴的朝向垂直于农作物,有助于喷嘴将农药均匀的喷洒到平坦的农作物上。
如图2所示的果树模式下无人飞行器的螺旋桨状态示意图,在果树模式下,无人飞行器的螺旋桨通常被设置为与无人飞行器所在的平面呈一定角度,以使得无人飞行器在水平面飞行时,螺旋桨与水平面呈一定角度,又由于喷嘴的朝向垂直于无人飞行器的机身,即平行于螺旋桨,从而喷嘴的朝向垂直于果树的树叶上,有助于将农药均匀的喷洒到果树的树叶上。
基于上述不同的螺旋桨状态,本申请在无人飞行器启动之前进行检测,若检测到螺旋桨状态信息和工作模式匹配时才会启动无人飞行器,避免在螺旋桨状态信息和工作模式不匹配的情况下启动无人飞行器,如此,有助于避免无人飞行器的异常,进而减少了安全隐患。
下面通过列举几个具体的实施例详细介绍本申请提供的一种无人飞行器启动方法、装置及无人飞行器。
参照图3,示出了本申请实施例的一种无人飞行器启动方法的流程图,具体可以包括:
101,获取所述无人飞行器的螺旋桨状态信息和工作模式。
其中,螺旋桨状态信息是指螺旋桨与机身的相对位置关系,可以用螺旋桨与机身之间的角度表示。螺旋将状态信息可以通过特定的外部设备检测得到。
工作模式是无人飞行器的模式,对于不同领域、不同型号的无人飞行器,其工作模式可能不同。例如,对于农业领域中,无人飞行器的工作模式分为大田模式和果树模式 两种。工作模式可以通过获取无人飞行器的控制器中的工作模式标识得到。
102,若所述螺旋桨状态信息与所述工作模式匹配,则以所述工作模式启动所述无人飞行器。
其中,螺旋桨状态信息为当前的真实螺旋桨状态信息。
在实际应用中,每个工作模式都设置有一个特定螺旋桨状态信息,若真实螺旋桨状态信息与该特定螺旋桨状态信息一致,则代表螺旋桨状态信息与工作模式匹配,此时可以以该工作模式启动无人飞行器。
此外,若真实螺旋桨状态信息与该特定螺旋桨状态信息不一致,则代表螺旋桨状态信息与工作模式不匹配,此时不可以以该工作模式启动无人飞行器。为了启动无人飞行器,可以调整工作模式,以使调整之后的工作模式的特定螺旋桨状态信息与真实螺旋桨状态信息一致;此外,还可以调整真实螺旋桨状态信息,以使调整之后的真实螺旋桨状态信息与工作模式的特定螺旋桨状态信息一致。
可选地,所述获取所述无人飞行器的螺旋桨状态信息,包括1011:
1011,通过状态信息检测装置检测所述无人飞行器的螺旋桨状态信息。
其中,状态信息检测装置可以安装于电机与机身之间的连接部件上,该连接部件用于改变螺旋桨和机身之间的相对位置关系,即改变螺旋桨状态信息,从而当检测螺旋桨和机身之间的相对位置关系被改变时,状态信息检测装置可以检测到螺旋桨和机身之间的相对位置关系。状态信息检测装置可以是任意可以检测螺旋桨和机身之间的相对位置关系的装置,包括但不限于:惯性测量装置、磁性元件和传感器、液态水银开关、光电编码器或其他光栅类传感器、三轴磁力计,其中,惯性测量装置是用于测量加速度的装置,可以分为宝石支承型、挠性支承型、气浮型、液浮型、磁悬浮型和静电悬浮型,磁性元件和传感器配套使用,传感器用于检测磁性元件。

10111,通过所述第一惯性测量装置测量所述第一惯性测量装置所在方向上的第一惯性加速度。
其中,第一惯性测量装置为用于测量加速度的惯性测量装置,第一惯性测量装置可以是单轴的惯性测量装置,用于测量其中一个方向的惯性加速度,第一惯性测量装置可以设置于机身和电机之间的连接部件上,如图4所示,在大田模式下连接部件平行于机身所在的平面,无人飞行器停在处于水平面的地面上时,安装于连接部件上的第一惯性测量装置和机身均平行于水平面,第一惯性测量装置测量的惯性加速度是水平方向上的惯性加速度,第一惯性加速度接近于0;如图5所示,在果树模式下连接部件与机身呈一定角度,无人飞行器停在处于水平面的地面上时,安装于连接部件上的第一惯性测量装置与水平面呈一定角度,第一惯性测量装置测量的惯性加速度是倾斜角度上的惯性加速度,由于重力加速度的作用,第一惯性加速度不为0,如图6所示,以图4或图5中机身右侧的第一惯性测量装置为例进行说明,a1是连接部件与机身之间的夹角,即第一惯性测量装置与机身之间的夹角,由于无人飞行器在处于水平面的地面上,从而由于重力加速度g的影响,第一惯性测量装置测量的第一惯性加速度ax=g*sin(a1),即a1=arcsin(ax/g)。
基于上述原理,若第一惯性测量装置测量的第一惯性加速度大于0,或根据第一惯性加速度计算得到的角度a1大于0,则代表无人飞行器的螺旋桨与机身呈一定夹角。
基于所述10111,所述若所述螺旋桨状态信息与所述工作模式匹配,则以所述工作模式启动所述无人飞行器,包括1021:
1021,若所述第一惯性加速度和所述工作模式的预设第一加速度一致,则以所述工作模式启动所述无人飞行器。
对于大田模式,预设第一加速度可以为0,但在实际应用中,由于第一惯性加速度可能因为外部原因不会严格的为0,可以将大田模式下的预设第一加速度设置为小于或等于预设加速度阈值,该预设加速度阈值可以是接近于0的很小的取值,即允许第一惯性加速度在接近于0的很小范围内波动。从而,若第一惯性加速度小于或等于该预设加速度阈值,则代表第一惯性加速度和大田模式的预设第一加速度一致,从而确定螺旋桨状态信息与大田模式匹配;若第一惯性加速度大于该预设加速度阈值,则代表第一惯性加速度和大田模式的预设第一加速度不一致,从而确定螺旋桨状态信息与大田模式不匹配。
对于果树模式,预设第一加速度可以为一个大于0的取值,具体地,可以将果树模式的预设第一加速度设置为大于预设加速度阈值,若第一惯性加速度大于该预设加速度阈值,则代表第一惯性加速度和果树模式的预设第一加速度一致,从而确定螺旋桨状态信息与果树模式匹配;若第一惯性加速度小于或等于该预设加速度阈值,则代表第一惯性加速度和果树模式的预设第一加速度不一致,从而确定螺旋桨状态信息与果树模式不匹配。
本申请可以通过第一惯性测量装置测量第一惯性加速度,并根据第一惯性加速度确定螺旋桨状态信息与工作模式是否匹配。
可选地,所述若所述螺旋桨状态信息与所述工作模式匹配,则以所述工作模式启动所述无人飞行器,包括10211至10212:
10211,根据重力加速度和所述第一惯性加速度确定所述第一惯性测量装置所在方向与水平面的夹角。

10212,若所述第一惯性测量装置所在方向与水平面的夹角和所述工作模式的预设第一夹角一致,则以所述工作模式启动所述无人飞行器。
对于大田模式,预设第一夹角可以为0,但在实际应用中,由于第一惯性测量装置所在方向与水平面的夹角可能因为外部原因不会严格的为0,可以将大田模式下的预设第一夹角设置为小于或等于预设夹角阈值,该预设夹角阈值可以是接近于0的很小的取值,即允许第一惯性测量装置所在方向与水平面的夹角在接近于0的很小范围内波动。从而,若第一惯性测量装置所在方向与水平面的夹角小于或等于该预设夹角阈值,则代表第一惯性测量装置所在方向与水平面的夹角和大田模式的预设第一夹角一致,从而确定螺旋桨状态信息与大田模式匹配;若第一惯性测量装置所在方向与水平面的夹角大于该预设夹角阈值,则代表第一惯性测量装置所在方向与水平面的夹角和大田模式的预设第一夹角不一致,从而确定螺旋桨状态信息与大田模式不匹配。
对于果树模式,预设第一夹角可以为大于0的取值,具体地,可以将果树模式的预设第一夹角设置为大于预设夹角阈值,若第一惯性测量装置所在方向与水平面的夹角大于该预设夹角阈值,则代表第一惯性测量装置所在方向与水平面的夹角和果树模式的预设第一夹角一致,从而确定螺旋桨状态信息与果树模式匹配;若第一惯性测量装置所在方向与水平面的夹角小于或等于该预设夹角阈值,则代表第一惯性测量装置所在方向与水平面的夹角和果树模式的预设第一夹角不一致,从而确定螺旋桨状态信息与果树模式不匹配。
本申请还可以通过第一惯性测量装置所在方向和水平面的夹角确定螺旋桨状态信息与工作模式是否匹配。
可选地,所述状态信息检测装置还包括:第二惯性测量装置和第三惯性测量装置, 所述螺旋桨状态信息还包括:第二方向上的第二惯性加速度和第三方向上的第三惯性加速度,所述若所述螺旋桨状态信息与所述工作模式匹配,则以所述工作模式启动所述无人飞行器,包括10213至10215:
10213,通过所述第二惯性测量装置测量第二方向上的第二惯性加速度。
其中,第二惯性测量装置是用于测量第二方向上的惯性加速度的惯性测量装置,在本申请中,将第二方向上的惯性加速度称为第二惯性加速度。
10214,通过所述第三惯性测量装置测量第三方向上的第三惯性加速度,所述第二方向垂直于所述第一惯性测量装置所在方向,所述第三方向垂直于所述第一惯性测量装置所在方向和所述第二方向所在的平面。
其中,第三惯性测量装置是用于测量第三方向上的惯性加速度的惯性测量装置,在本申请中,将第三方向上的惯性加速度称为第三惯性加速度。本申请中的第一方向、第二方向、第三方向形成了一个三维坐标系。如图7所示,以图4或图5中机身右侧第一惯性测量装置为例,X轴为第一方向,Y轴为第二方向、Z轴为第三方向,三者形成了一个三维坐标系,X轴上设置有第一惯性测量装置,Y轴上设置有第二惯性测量装置,Z轴上设置有第三惯性测量装置,图7中x轴和y轴分别是X轴和Y轴在水平面上的投影。

在实际应用中,螺旋桨在几个方向上均可能有一定程度的变化,为了更准确的确定螺旋桨状态信息,本申请结合了三个方向上的惯性加速度来进行判断。
具体地,对于大田模式,预设第一加速度为0,且预设第二加速度为0,且预设第三加速度为0,但在实际应用中,由于第一惯性加速度、第二惯性加速度和第三惯性加速度可能因为外部原因不会严格的为0,可以将大田模式下的预设第一加速度、预设第二加速度和预设第三加速度均设置为小于或等于预设加速度阈值,该预设加速度阈值可以是接近于0的很小的取值,即允许第一惯性加速度、第二惯性加速度和第三惯性加速度在接近于0的很小范围内波动。从而,若第一惯性加速度、第二惯性加速度和第三惯性加速度均小于或等于该预设加速度阈值,则代表第一惯性加速度和大田模式的预设第一加速度一致,且第二惯性加速度和大田模式的预设第二加速度一致,且第三惯性加速度和大田模式的预设第三加速度一致,从而确定螺旋桨状态信息与大田模式匹配;若第一惯性加速度大于该预设加速度阈值,或第二惯性加速度大于该预设加速度阈值,或第三惯性加速度大于该预设加速度阈值,则代表第一惯性加速度和大田模式的预设第一加速度不一致,或第二惯性加速度和大田模式的预设第二加速度不一致,或第三惯性加速度和大田模式的预设第三加速度不一致,从而确定螺旋桨状态信息与大田模式不匹配。
对于果树模式,预设第一加速度为大于0的取值,预设第二加速度和预设第三加速度均为0,具体地,可以将果树模式的预设第一加速度设置为大于预设加速度阈值,预设第二加速度和预设第三加速度均设置为小于或等于预设加速度阈值,若第一惯性加速度大于该预设加速度阈值,且第二惯性加速度小于或等于该预设加速度阈值,且第三惯性加速度小于或等于该预设加速度阈值,则代表第一惯性加速度和果树模式的预设第一加速度一致,第二惯性加速度和果树模式的预设第二加速度一致,第三惯性加速度和果树模式的预设第三加速度一致,从而确定螺旋桨状态信息与果树模式匹配;若第一惯性加速度小于或等于该预设加速度阈值,或第二惯性加速度大于该预设加速度阈值,或第三惯性加速度大于该预设加速度阈值,则代表第一惯性加速度和果树模式的预设第一加速度不一致,或第二惯性加速度和果树模式的预设第二加速度不一致,或第三惯性加速度和果树模式的预设第三加速度不一致,从而确定螺旋桨状态信息与果树模式不匹配。

具体地,对于大田模式,预设第一夹角、预设第二夹角和预设第三夹角可以为0,但在实际应用中,由于第一惯性测量装置所在方向与水平面的夹角、第二方向与水平面的夹角、第三方向与竖直面的夹角可能因为外部原因不会严格的为0,可以将大田模式下的预设第一夹角、预设第二夹角和预设第三夹角均设置为小于或等于预设夹角阈值,该预设夹角阈值可以是接近于0的很小的取值,即允许第一惯性测量装置所在方向与水平面的夹角、第二方向与水平面的夹角、第三方向与竖直面的夹角在接近于0的很小范围内波动。从而,若第一惯性测量装置所在方向与水平面的夹角小于或等于该预设夹角阈值,且第二方向与水平面的夹角小于或等于该预设夹角阈值,且第三方向与竖直面的夹角小于或等于该预设夹角阈值,则代表第一惯性测量装置所在方向与水平面的夹角和大田模式的预设第一夹角一致,且第二方向与水平面的夹角和大田模式的预设第二夹角一致,且第三方向与竖直面的夹角和大田模式的预设第三夹角一致,从而确定螺旋桨状态信息与大田模式匹配;若第一惯性测量装置所在方向与水平面的夹角大于该预设夹角阈值,或第二方向与水平面的夹角大于该预设夹角阈值,或第三方向与竖直面的夹角大于 该预设夹角阈值,则代表第一惯性测量装置所在方向与水平面的夹角和大田模式的预设第一夹角不一致,或第二方向与水平面的夹角和大田模式的预设第二夹角不一致,或第三方向与竖直面的夹角和大田模式的预设第三夹角不一致,从而确定螺旋桨状态信息与大田模式不匹配。
