相关技术中,无人机的播撒系统在播撒物时,是将物料颗粒水平甩出,物料颗粒经平抛的方式落至地面,物料颗粒向下的运动仅依靠重力,无法实现控制物料按预定方向定向播撒。
发明内容
针对现有技术中的上述缺陷,本发明实施例提供一种农业植保无人机、播撒控制方法及存储介质。
本发明实施例第一方面提供一种农业植保无人机,包括机身和播撒设备,所述播撒设备安装于所述农业植保无人机的机身上,所述播撒设备包括:
播撒盘,包括进料口、播撒口以及甩盘,在所述安装状态下,所述甩盘的转动平面与所述农业植保无人机的航向轴的夹角大于或等于0°,且小于90°;播撒物通过所述进料口进入所述甩盘内,并通过所述播撒口甩出;所述播撒口朝向所述农业植保无人机的下方或斜下方;
驱动装置,与所述播撒盘连接,用于驱动所述甩盘转动,从而产生离心力给所述甩盘内的播撒物,以使所述播撒物在所述离心力的作用下从所述播撒口甩出。
本发明实施例第二方面提供一种农业植保无人机的播撒控制方法,包括:

调节所述驱动装置的驱动参数,以调整所述播撒物向下抛出的倾斜角度。
本发明实施例第三方面提供一种计算机可读存储介质,其上存储有计算机程序,所述计算机程序可被处理器执行以下方法:

调节所述驱动装置的驱动参数,以调整所述播撒物向下抛出的倾斜角度。
本发明实施例提供的农业植保无人机、播撒控制方法及存储介质,通过将播撒设备的甩盘设计成转动平面与农业植保无人机的航向轴的夹角为大于或等于0°且小于90°的形式,而甩盘上的播撒口朝向农业植保无人机的下方或斜下方,使得物料颗粒在农业植保无人机的下方或斜下方通过离心力直接甩出,而非以平抛的形式甩出,竖直方向上的初速度大,因此有效提高了播撒设备的定向播撒的能力,并且具有高效、便捷的优点。

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。
除非另有定义,本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的,不是旨在于限制本发明。
在通篇说明书及权利要求当中所提及的“包括”为一开放式用语,故应解释成“包括但不限定于”。“大致”是指在可接收的误差范围内,本领域技术人员能够在一定误差范围内解决所述技术问题,基本达到所述技术效果。

发明人经过创造性地劳动发现,现有技术中对于农业播撒物的播撒,通常采用以下传统的播撒方式:1、轮式拖拉机搭载播撒机,该种方式效率低,且容易压坏农作物。2、人工背负式播撒机,该种方式人工作业强度高,有毒物料损伤人体,且效率低。3、手抛式,人工作业强度高,有毒物料损伤人体,且效率低。
为解决上述传统播撒方式的弊端,相关技术中有利用农业植保无人机播撒物料的方式,但其是利用高速气流将种子、肥料等固体颗粒喷向地面,但是由于无人机在飞行时,螺旋桨高速转动,气流较大,而播撒系统的气流没有无人机螺旋桨的气流强,会使得螺旋桨的气流阻碍播撒物料按照预设方向播撒,使得颗粒物反向拍回地面,无法达到精准定向播撒的目的。
为解决现有技术中的上述技术问题,本发明提供一种农业植保无人机及农业植保无人机的控制方法,能够提高定向播撒的能力,并且具有高效、便捷的优点。
实施例一
图1为本发明一实施例提供的农业植保无人机的结构简图;图6为本发明实施例提供的农业植保无人机的电控原理图一。请参照附图1和附图 6,本实施例提供的农业植保无人机,包括机身10和播撒设备20,播撒设备20安装于农业植保无人机的机身10上,播撒设备20包括:播撒盘21和驱动装置30。具体的,播撒设备20可以固定地挂载于农业植保无人机的下方,以保证农业植保无人机的重心平稳。播撒设备20可以单独从农业植保无人机上拆卸下来,以便于对播撒设备20的维修或更换。
具体的,播撒盘21包括进料口211、播撒口212以及甩盘213,播撒物通过进料口211进入甩盘213内,并通过播撒口212甩出;播撒口212朝向农业植保无人机的下方或斜下方。驱动装置30与播撒盘21连接,用于驱动甩盘213转动,从而产生离心力给甩盘213内的播撒物,以使播撒物在离心力的作用下从播撒口212甩出。
具体的,本实施例所描述的播撒物可以包括以下至少一种:粉末状肥料、种子颗粒、农药等。
在本实施例中,对于甩盘213的形状、大小、材料不做限定,本领域技术人员可以根据实际需要来选择或设计。在一优选实施例中,甩盘213的整体形状可以呈圆盘状,并且整个甩盘213可以为金属材料制成,强度较好,性能稳定,不易变形,当然,在其他一些实施例中,甩盘213也可以为塑料材料制成。
需要说明的是,播撒盘21至少包括可转动的甩盘213,在其他一些实施例中,播撒盘21除了包括可转动地甩盘213之外,还可以包括不可转动的固定盘(图中未示出),该固定盘可以包括两个,甩盘213可以设于两个固定盘之间,固定盘可以用于挡住播撒物,防止播撒物在甩盘213的两侧飞溅,更进一步保证播撒物沿预定方向播撒。固定盘的结构形状可以与甩盘213的大小和形状相同,且固定盘的材料可以与甩盘213的材料相同,以便于成型,简化加工工艺。
在本实施例中,播撒口212可以位于播撒盘21的边缘位置,或者靠近边缘的位置,且播撒口212可以仅具有一个,甩盘213在转动过程中, 只有在播撒口212转动到下方时,播撒物才能被甩出。而进料口211可以设于甩盘213的中心位置,以使得播撒盘21在转动时,进料口211不会跟随转动,不影响进料口211的进料。
更进一步的,在本实施例中,优选的,甩盘213的径向边缘具有一开口,该开口形成播撒口212,在甩盘213内具有与播撒口212连通的播撒通道(图中未示出),该播撒通道与还与进料口211连通。
当然,在其他一些实施例中,甩盘213与固定盘之间可以形成播撒通道,而播撒口213可以形成于播撒通道的末端。
在安装状态下,甩盘213的转动平面与农业植保无人机的航向轴的夹角大于或等于0°,且小于90°。也就是说,甩盘213的转动平面并非水平设置,甩盘213可以在例如电机等驱动装置30的驱动下高速转动,以产生较大的离心力,将播撒盘21的播撒物经播撒口212甩出,具体的,播撒物在播撒口212可以以与甩盘213的轮廓相切的方向甩出,由于甩盘213非水平设置,因此,播撒物甩出时,具有竖向初速度,使得播撒物的定向播撒能力得以提高。
值得注意的是,当甩盘213的转速较高时,播撒口212可以在未完全到达正下方时即可将播撒物沿斜向切线甩出,而当甩盘213的转速较低时,播撒口212在接近于或位于正下方时才将播撒物甩出,因此,可以通过控制甩盘213的转速控制播撒物的播撒距离。并且,可以理解的是,当甩盘213的转向不同时,播撒物所甩出的方向也不同,例如,如图1所示,甩盘213逆时针转动,播撒物沿右下方甩出(如图1虚线所示为播撒物甩出轨迹),而甩盘213顺时针转动时,则播撒物会沿左下方甩出。从而可以通过驱动装置控制甩盘213的转速和/或转向来达到定向播撒的目的。
优选的,在本实施例中,在安装状态下,甩盘213的转动平面与农业植保无人机的航向轴的夹角小于等于45度。甩盘213的转动平面与农业植保无人机的航向轴的夹角较小,使得甩盘213在高速转动时所产生的离 心力将播撒物甩出时,播撒物的甩出方向尽可能朝下,而使得竖向初速度尽可能大,水平方向的初速度尽可能小。可以理解的是,在甩盘213以同等转速转动的前提下,甩盘213的转动平面与农业植保无人机的航向轴的夹角越小,播撒物甩出时的竖向初速度越大,定向播撒能力越强。
本发明实施例提供的农业植保无人机,通过将播撒设备的甩盘设计成转动平面与农业植保无人机的航向轴的夹角为大于或等于0°且小于90°的形式,而甩盘上的播撒口朝向农业植保无人机的下方或斜下方,使得物料颗粒在农业植保无人机的下方或斜下方通过离心力直接甩出,而非以平抛的形式甩出,竖直方向上的初速度大,其运动轨迹接近于直线,因此提高了播撒设备的定向播撒的能力,并且具有高效、便捷的优点。
更优选的,在安装状态下,甩盘213的转动平面可以基本平行于农业植保无人机的航向轴。需要说明的是,所谓基本平行,是指在安装或制造误差允许的范围内,两者之间的夹角可以在-5°至+5°范围内。此时,甩盘213的转动平面大致与农业植保无人机的航向轴平行,甩盘213基本竖向布置,使得播撒物基本能够按照预定的落地方向从甩盘213甩出,使得播撒范围最为可控,定向播撒能力最强。
图2为本发明另一实施例提供的农业植保无人机的播撒设备的第一播撒状态示意图;图3为本发明另一实施例提供的农业植保无人机的播撒设备的第二播撒状态示意图;图4为本发明另一实施例提供的农业植保无人机的播撒设备的第三播撒状态示意图;图5本发明另一实施例提供的农业植保无人机的播撒设备的第四播撒状态示意图。请参照附图2-附图5,本实施例提供的播撒盘21包括至少两个(图2至图5中所示出的播撒盘21为两个),在安装状态下,至少两个播撒盘21在农业植保无人机的横滚轴方向上并列或交错设置。在一些实施例中,在安装状态下,至少两个播撒盘21在农业植保无人机的俯仰轴方向上并列或交错设置。
需要说明的是,所谓交错设置,是指至少两个播撒盘21分别相对于 航向轴倾斜设置,以使得至少两个播撒盘21所在的转动平面具有交线。
当至少两个播撒盘21在横滚轴方向上并列或交错设置,并且两个播撒盘21的转向不同时,可以使得播撒物在农业植保无人机的机身10的前后方向播撒。当至少两个播撒盘21在俯仰轴方向行并列或交错设置,并且两个播撒盘21的转向不同时,可以使得播撒物在农业植保无人机的机身10的左右方向播撒。通过设置至少两个播撒盘21,能够有效地提高播撒效率。
当播撒盘21的数量包括至少两个,对应的,甩盘213的数量包括至少两个,在安装状态下,至少两个播撒盘21在农业植保无人机的横滚轴方向上排布设置,至少两个甩盘213的转动平面与农业植保无人机的航向轴之间的夹角大小基本相等,且至少两个甩盘213的转动平面的倾斜方向相反。至少两个播撒盘21在农业植保无人机的横滚轴方向上排布设置,并且,至少两个甩盘213的转动平面的倾斜方向相反,且倾斜角度基本相等,使得至少两个甩盘213的播撒物尽量在机身10的前后方向上对称甩出,提高农业植保无人机的播撒均匀性。
可选的,播撒盘21的数量包括至少两个,对应的,甩盘213的数量包括至少两个,在安装状态下,至少两个播撒盘21在农业植保无人机的俯仰轴方向上排布设置,且至少两个播撒盘21分别朝横滚轴方向倾斜,至少两个甩盘213的转动平面的倾斜方向相反。同样的,至少两个甩盘213的转动平面倾斜方向相反,且倾斜角度基本相同,使得至少两个甩盘213的播撒物尽量在机身10上关于横滚轴和俯仰轴分别对称甩出,提高农业植保无人机的播撒均匀性。
进一步的,驱动装置30可以通过驱动至少两个播撒盘21以不同的转速和转向转动,可以实现农业植保无人机以不同的播撒模式甩出播撒物,提高农业植保无人机的作业灵活性。
下面具体结合图2至图5,举例来说明农业植保无人机的不同播撒模 式。
如图2所示,两个播撒盘21沿横滚轴方向排布,且两个播撒盘21的甩盘213的转动平面均平行于航向轴。左侧的播撒盘21逆时针转动,播撒物从左侧的播撒盘21的播撒口212沿右下方甩出,右侧的播撒盘21顺时针转动,播撒物从右侧的播撒盘21的播撒口212沿左下方甩出,使得两个播撒盘21下方的播撒物相互靠近地朝中部集中播撒。
如图3所示,两个播撒盘21沿横滚轴方向排布,且两个播撒盘21的甩盘213的转动平面均平行于航向轴。左侧的播撒盘21顺时针转动,播撒物从左侧的播撒盘21的播撒口212沿左下方甩出,右侧的播撒盘21逆时针转动,播撒物从左侧的播撒盘21的播撒口212沿右下方甩出,使得两个播撒盘21下方的播撒物相互远离地朝机身10下方的两侧甩出。
如图4所示,两个播撒盘21沿横滚轴方向排布,且两个播撒盘21的甩盘213的转动平面均平行于航向轴。左侧的播撒盘21逆时针转动,播撒物从左侧的播撒盘21的播撒口212沿右下方甩出,右侧的播撒盘21逆时针转动,播撒物从右侧的播撒盘21的播撒口212沿右下方向甩出,使得两个播撒盘21下方的播撒物朝同一方向甩出,实现右侧定点播撒。
如图5所示,两个播撒盘21沿横滚轴方向排布,且两个播撒盘21的甩盘213的转动平面均平行于航向轴。左侧的播撒盘21顺时针转动,播撒物从左侧的播撒盘21的播撒口212沿左下方甩出,右侧的播撒盘21顺时针转动,播撒物从右侧的播撒盘21的播撒口212沿左下方向甩出,使得两个播撒盘21下方的播撒物朝同一方向甩出,实现左侧定点播撒。
另外,可以理解的是,甩盘213的转速不同,播撒物所甩出的距离也不同,转速越快,播撒物所甩出的距离越远,转速越慢,播撒物所甩出的距离越近,因此可以根据不同的播撒需求,控制每个播撒盘21的甩盘213的转向和转速实现播撒物的定点播撒。
值得注意的是,当农业植保无人机只有一个播撒盘21时,由于甩盘 213转动,播撒物只能在甩盘213向下的180°范围内的任意位置甩出,但是并不一定是正下方甩出,则此时便会出现左右两侧落料稀疏程度不一致的问题,例如如图1所示,落料偏右,会使得右侧落料较密,左侧落料较稀疏。而当采用两个播撒盘21以图2或图3中不同的转动方向转动时,会使得机身左右两侧的落料对称互补,左右两侧落料稀疏程度一致,提高播撒均匀性。
当然,可以理解的是,本实施例的农业植保无人机的播撒盘21并不限于两个,例如还可以为三个、四个等,当农业植保无人机的播撒盘21为三个时,三个播撒盘21可以沿横滚轴的方向排布,机身10前后两端的播撒盘21的甩盘213的转动平面可以分别朝前和朝后倾斜,且倾斜角度相等,中间位置的播撒盘21的甩盘213的转动平面竖直向下。当农业植保无人机的播撒盘21为四个时,沿横滚轴方向上可以排布两个播撒盘21,沿俯仰轴方向上可以排布两个播撒盘21,四个播撒盘21的连线可以构成正方形,且在俯仰轴方向上排布的播撒盘21的甩盘213可以对称设置,在横滚轴方向上排布的播撒盘21的甩盘213可以对称设置。由此,提高了播撒宽度和播撒范围的同时,保证了播撒的均匀性。
本实施例的播撒设备还包括外部存储容器,播撒物可以容纳于与播撒盘21相独立的外部存储容器中,并通过外部存储容器的出料口流向播撒盘21中,以从播撒盘21甩出,在该种方式下,播撒盘21的进料口211可以与外部存储容器的出料口连通。具体的,外部存储容器可以为装料箱22,装料箱22设于播撒盘21的上方,装料箱22用于容纳播撒物,装料箱22上可以具有出料口221,出料口221与进料口211通过进料通道连通,进料通道用于引导播撒物从装料箱22进入甩盘213的播撒通道。通过设置装料箱22,保证农业植保无人机可以具有较大的播撒物存储量,而无需频繁添加播撒物,降低劳动程度。
装料箱22包括一个,播撒盘21包括至少两个,装料箱22上的出料 口221的数量与甩盘213的数量相等,每个播撒盘21上各具有一进料口211,装料箱22上的各个出料口221分别对应连通一个播撒盘21的进料口211。或者,装料箱22的数量与播撒盘21的数量相等,且各个装料箱22的出料口221分别对应连通一个播撒盘21的进料口。至少两个播撒盘21共用一个装料箱22,使得播撒物容纳于一个空间内,而避免多个存储容器中所容纳的播撒物的量不同而使得进入到各个播撒盘21的播撒物的量差异较大的问题,有效地减小进入各个播撒盘21的播撒物的量的差异,使得从各个播撒盘21甩出的播撒物的量基本相同,使得播撒物能够更为均匀地播撒。当然,在其他一些实施例中,装料箱22的数量可以与甩盘213的数量相等,一个装料箱22可以对应一个甩盘213。
另外,在其他一些实施例中,播撒盘21内部可以具有用于存储和容纳播撒物的仓体,播撒物可以全部容纳于播撒盘21的内部的仓体,在该种方式下,播撒盘21的进料口211可以与播撒盘21的内部仓体的出料口连通,在甩盘213转动时,播撒盘21内部的仓体的播撒物从出料口流出至播撒盘21的进料口,并经过播撒盘21的播撒口212甩出。
如图6所示,在上述实施例的基础上,进一步的,播撒设备还可以包括:调节装置40。调节装置40用于调节进料口211的进料量。由此可以根据不同的播撒需求调节进料口211的进料量,提高农业植保无人机的播撒灵活性。
具体而言,调节装置40可以设于进料通道,调节装置40可以包括调节阀,调节阀可以具体调节进料口211的开度,从而调节进料口211的进料量。调节装置40可以设于进料通道的任何位置处,例如,可以设于进料口211,也可以设于进料通道的中部。
图7为本发明实施例提供的农业植保无人机的电控原理图二,如图7所示,本实施例的农业植保无人机还包括第一采集装置50,第一采集装置50用于采集播撒物的颗粒信息,调节装置40与第一采集装置50连接,调 节装置40用于根据第一采集装置50所采集的播撒物的颗粒信息而调节进料口211的进料量。
具体的,播撒物的颗粒信息包括以下至少一种:颗粒质量、颗粒大小、颗粒密度。需要说明的是,本实施例中所指的颗粒并不一定是固体颗粒,例如种子颗粒、粉末颗粒;还可以包括液体颗粒,例如农药液化后的颗粒。
在本实施例中,农业植保无人机还可以通信连接有输入装置(图中未示出),输入装置可以为位于地面端的移动终端,或者,输入装置位于机身10上,例如,输入装置为位于机身10上的触摸屏,或者带操作键盘的显示屏。输入装置可以与第一采集装置50连接,第一采集装置50可以采集输入装置所输入的颗粒信息,在利用该植保无人机进行播撒之前,或者在利用该植保无人机进行播撒的过程中,用户可以主动输入颗粒信息。在一些可选的实施例中,第一采集装置50可以包括高浓度颗粒计数器,重量传感器、颗粒检测仪等检测和采集颗粒信息。第一采集装置50将颗粒信息发送给调节装置40,使得调节装置40调节进料口211的进料量。
不同重量,不同密度的颗粒在同样的甩盘213转速下,所甩出的轨迹不同。甩盘213在转动的过程中,播撒口跟随转动,根据颗粒数量和重量的不同,调节进料口211的进料量,即控制进料口211的流量,可以使得甩盘213的转动时,只有播撒口212转动至下方时播撒物才能被甩出,而避免出现播撒物从甩盘213上方甩出的情况发生。
进一步的,调节装置40还与驱动装置30连接,调节装置40还用于根据播撒物的颗粒信息,以及驱动装置30的驱动参数调节进料通道的开度以调节进料口211的进料量。由于驱动装置30是用于驱动甩盘213转动的,甩盘213的转速、转向、转动频率的不同,对播撒物的甩出轨迹也有影响,因此,本实施例的调节装置40根据驱动装置的驱动参数和播撒物的颗粒信息来调节进料口211的进料量,其中,驱动参数包括以下至少一种:电机转速、电机转向、电机频率。由此,来达到播撒口212转动至 下方时播撒物才被甩出的目的。而具体如何根据驱动装置的驱动参数和播撒物的颗粒信息来调节进料口211的进料量,可以根据实际情况具体设计,或者经过多次试验模拟或测试得到,本实施例不做特别限定。
进一步的,本实施例提供的农业植保无人机还包括:处理装置70,处理装置70与驱动装置30连接,用于确定驱动装置30的驱动参数;控制装置60与处理装置70和驱动装置30连接,用于根据处理装置70所确定的目标驱动参数,调节驱动装置30的驱动参数,以使驱动装置30根据所确定的目标驱动参数驱动甩盘213转动。
需要说明的是,在本实施例中,驱动装置30可以为电机,而控制装置60可以为电机内的控制芯片,也可以为独立于电机的控制设备,本实施例不做限定,只要是控制装置60与驱动装置30内的驱动模块具有电连接关系,并且能够给控制信号给驱动模块而使得驱动模块驱动均可,本实施例不做特别限定。
进一步的,本实施例的农业植保无人机还包括:第二采集装置80。第二采集装置80可以用于采集用户输入驱动参数;处理装置70与第二采集装置80连接,处理装置70可以具体用于根据用户输入的驱动参数确定为驱动装置30的目标驱动参数。用户除了可以输入颗粒物的颗粒信息之外,类似的,用户还可以通过输入装置输入所希望驱动装置驱动的驱动参数,例如,用户可以直接在输入装置输入甩盘213的转速、转向等参数,需要说明的是,可以预先定义“+”为正转(顺时针转)“—”为反转(逆时针转),用户可以直接输入“+”或“—”以选择甩盘213的转向。处理装置70可以将用户所输入的驱动参数确定为驱动装置30的驱动参数,控制装置60控制驱动装置30以所确定的目标驱动参数驱动甩盘213转动。
需要说明的是,本实施例中的输入装置可以为与输入颗粒信息所对应的输入装置,也可以为另外设置的其他输入装置,本实施例不做限定。
进一步的,处理装置70还与农业植保无人机的飞行控制系统90和农 业植保无人机的拍摄设备100连接;处理装置70具体用于根据农业植保无人机的轨迹信息、农业植保无人机的姿态信息、拍摄设备所拍摄的图像信息中的至少一个确定驱动装置的驱动参数。
由于农业植保无人机以不同姿态飞行时,播撒设备所甩出的播撒物的落地点也会不同,而农业植保无人机处于不同位置(也就是无人机的飞行轨迹)时,播撒设备上所甩出的播撒物的落地点也会不同,拍摄设备所拍摄的图像信息可以准确反映农业植保无人机下方地面图像,因此可以准确获知待播撒区域,而驱动装置的驱动参数决定甩盘的转速和转向,由此决定播撒物的甩出轨迹和最终的播撒点。因此通过农业植保无人机的轨迹信息、农业植保无人机的姿态信息、拍摄设备所拍摄的图像信息中的至少一个确定驱动装置的驱动参数,能够使得播撒设备根据实际播撒需求进行播撒,实现精准、定向播撒的目的。
