Description

可移动平台的作业规划方法、设备和存储介质 技术领域
本发明涉及可移动平台领域,尤其涉及一种可移动平台的作业规划方法、设备和存储介质。
背景技术
随着农业的发展,农业机械化由于可以解放较多的农业人力,也得到越来越多的重视。特别是,在农业植保范围内,可以利用植保设备或植保平台来在植保区域中进行喷洒或播撒等植保作业。
然而,很多情况下作业区域对应的作业量的分布并不均匀,例如长势较好的区域需要喷洒的农药较少,而受虫害影响较大的区域需要喷洒的农药较多。目前的植保作业过程中可移动平台的最大移动速度取决于作业区域中的最大作业量,以保证最大作业量对应的区域实施了充分的作业。这就可能导致根据最大作业量确定的最大移动速度过小,使得整个植保作业过程中移动速度过慢,严重影响作业效率。因此,如何保证植保作业效率以及植保作业需求是很重要的问题。
发明内容
本发明实施例提供了一种可移动平台的作业规划方法、设备和存储介质,既可以保证植保作业的效率又可以满足植保作业需求。
本发明实施例的第一方面是为了提供一种可移动平台的作业规划方法,所述方法包括:获取可移动平台的作业区域中各个子区域对应的作业量中的最大作业量;根据所述最大作业量确定所述可移动平台的第一移动速度;若所述第一移动速度大于预设速度阈值,则将所述第一移动速度作为所述可移动平台对所述作业区域进行作业时的最大移动速度;若所述第一移动速度小于预设速度阈值,则根据所述各个子区域对应的作业量确定平均作业量,根据所述最大作业量和所述平均作业量确定所述可移动平台的第二移动速度,并将所述第二移动速度作为所述可移动平台对所述作业区域进行作业时的最大移动速度,所述第二移动速度大于或等于所述第一移动速度。
本发明实施例的第二方面是为了提供一种可移动平台的作业规划方法,所述方法包括:获取可移动平台的作业区域中各个子区域对应的作业量;根据所述各个子区域对应的作业量确定平均作业量;根据所述平均作业量和预设补偿比例,确定所述可移动平台对所述作业区域进行作业时的最大移动速度。
本发明实施例的第三方面是为了提供一种可移动平台的作业规划设备,包括:存储器、处理器;所述存储器,用于存储计算机程序;所述处理器调用所述计算机程序,以实现如下步骤:获取可移动平台的作业区域中各个子区域对应的作业量中的最大作业量;根据所述最大作业量确定所述可移动平台的第一移动速度;若所述第一移动速度大于预设速度阈值,则将所述第一移动速度作为所述可移动平台对所述作业区域进行作业时的最大移动速度;若所述第一移动速度小于预设速度阈值,则根据所述各个子区域对应的作业量确定平均作业量,根据所述最大作业量和所述平均作业量确定所述可移动平台的第二移动速度,并将所述第二移动速度作为所述可移动平台对所述作业区域进行作业时的最大移动速度,所述第二移动速度大于或等于所述第一移动速度。
本发明实施例的第四方面是为了提供一种可移动平台的作业规划设备,包括:存储器、处理器;所述存储器,用于存储计算机程序;所述处理器调用所述计算机程序,以实现如下步骤:获取可移动平台的作业区域中各个子区域对应的作业量;根据所述各个子区域对应的作业量确定平均作业量;根据所述平均作业量和预设补偿比例,确定所述可移动平台对所述作业区域进行作业时的最大移动速度。
本发明实施例的第五方面是为了提供一种计算机可读存储介质,所述存储介质为计算机可读存储介质,该计算机可读存储介质中存储有程序指令,所述程序指令用于第一方面和第二方面所述的方法。
本发明实施例将根据最大作业量确定的可移动平台的第一移动速度与预设速度阈值进行比较;若第一移动速度大于预设速度阈值,则将第一移动速度作为可移动平台对作业区域进行作业时的最大移动速度;若第一移动速度小于预设速度阈值,则根据最大作业量和平均作业量确定可移动平台的第二移动速度,并将第二移动速度作为可移动平台对作业区域进行作业时的最大移动速度,第二移动速度大于或等于第一移动速度。由此可以提高可移动平 台的作业速度,从而提高可移动平台的作业效率。同时,由于第二移动速度是基于最大作业量和平均作业量来确定的,还可以兼顾作业区域中的作业量,以满足作业需求。
相对的,本申请实施例还可以直接根据各个子区域对应平均作业量和预设补偿比例,确定可移动平台对作业区域进行作业时的最大移动速度,从而兼顾作业需求以及作业效率。

本申请实施例提供了可移动平台的作业规划方法,可以在保证作业量需求的同时,提高作业效率。
下面结合附图,对本发明的一些实施方式作详细说明。在各实施例之间不冲突的情况下,下述的实施例及实施例中的特征可以相互组合。
图1为本发明实施例提供的一种可移动平台的作业规划方法的流程示意图;本申请实施例提供方法可以由可移动平台执行,或者由可移动平台的控制设备执行。可移动平台可以是无人机,智能移动机器人、智能移动小车等可移动的智能设备。控制设备可以包括遥控器、手机、电机、平板电脑,笔记本电脑中的一种或多种。该方法100包括以下步骤:
101:获取可移动平台的作业区域中各个子区域对应的作业量中的最大作业量。
102:根据最大作业量确定可移动平台的第一移动速度。
103:若第一移动速度大于预设速度阈值,则将第一移动速度作为可移动平台对作业区域进行作业时的最大移动速度。
104:若第一移动速度小于预设速度阈值,则根据各个子区域对应的作业量确定平均作业量,根据各个子区域对应的作业量中的最大作业量和平均作业量确定可移动平台的第二移动速度,并将第二移动速度作为可移动平台对作业区域进行作业时的最大移动速度。
其中,第二移动速度大于或等于第一移动速度。
以下针对上述步骤进行详细的阐述:
101:获取可移动平台的作业区域中各个子区域对应的作业量中的最大作业量。
其中,作业区域可以是指植保作业中的作业区域,如一块需要待播种的田地。其中,该作业区域还可以按照一定的尺寸被划分为多个小区域,即子区域。每个子区域可以具有对应的作业量。该作业量可以是指该子区域需要作业的需求量,即需要量。如喷洒农药的用量,播撒种子的用量等。凡是可以用于植保作业的作业用量均可。
其中,获取可移动平台的作业区域中各个子区域对应的作业量的方式,可以包括:通过可移动平台的作业区域的处方图,获取可移动平台的作业区域中各个子区域对应的作业量。
其中,处方图指示了作业区域中各个子区域对应的作业量。且该处方图还可以具有对应的地理位置以及各个子区域也具有对应的地理位置。
该处方图的生成过程可以是通过可移动平台的控制设备生成的,也可以 是可移动平台生成。控制设备例如可以是遥控器、手机以及电脑等。该遥控器、手机以及电脑是可以具有显示组件的,如显示器,其可以提供上述生成的处方图给对应的用户进行查看以及修改。此外,还可以提供真实图像,以及该真实图像被划分好的栅格,并由用户来指示该作业区域的最大作业量,也可以由用户来指示各个子区域的作业量。在用户指示了最大作业量后,可以自动地确定作业区域中各个栅格的作业量。例如,对于喷洒农药的植保作业而言,可以对真实图像中的植被进行识别,确定出该图像中植被的生长趋势。基于生长趋势以及用户指定的最大作业量,来确定出各个栅格对应的作业量,如农药喷洒量。当然,也可以直接根据生长趋势确定该对应的作业量。其中,该作业量可以以亩为单位进行作业,也可以以其它为单位进行作业,此处就不再赘述。
针对控制设备生成的处方图,控制设备可以将其上传给可移动平台,如无人机等。如图2所示,可移动平台,如无人机等执行步骤201:获取处方图。
针对可移动平台生成的处方图,可移动平台,如无人机可以直接获取到生成的处方图。即执行步骤201:获取处方图。
在获取到处方图后,对该处方图进行解析,获取到该处方图对应作业区域中各个子区域的作业量。例如,无人机接收到对目标地块中的植被进行农药喷洒的处方图。则执行步骤202:解析处方图,获取处方图中各个栅格的亩用量,即每亩的作业量,如每亩的农药喷洒量。
还需要说明的是,除了通过处方图来获取对应的作业量,也可以直接通过其它形式来获取,如数据表等。其可以记录上述必要的信息,如地理位置,对应的作业量等。
102:根据最大作业量确定可移动平台的第一移动速度。
其中,根据前文所述,可移动平台,如无人机,在获取到该处方图中对应作业区域中各个子区域的作业量。可以确定出最大作业量。例如,如图2所示,执行步骤203:确定亩用量的最大值。在得到亩用量的最大值后,执行步骤204:基于亩用量的最大值,确定对应的第一移动速度。
具体的,根据最大作业量确定可移动平台的第一移动速度,包括:根据最大作业量和可移动平台的最大流量,确定可移动平台的第一移动速度。
然后可以通过下式1)来确定:
Figure PCTCN2020127597-appb-000001
其中,V max为第一移动速度,flow max为可移动平台的最大流量,如,可移动平台的最大喷洒量或最大播撒量。Mu表示最大作业量,如亩用量的最大值,也可以称为最大亩用量,L表示作业间距,如移动轨迹之间的间距。图3示出了可移动平台的移动轨迹图。如图3所示,可移动平台按照移动轨迹301进行移动,其中,L为302,是两条移动轨迹之间的距离。且该移动轨迹是预置好的,例如,在获取了作业区域的边界信息后,可以基于该边界信息确定移动轨迹。
由此,可以得到第一移动速度。
103:若第一移动速度大于预设速度阈值,则将第一移动速度作为可移动平台对作业区域进行作业时的最大移动速度。
例如,如图2所示,根据前文所述,可移动平台,如无人机在获取到第一移动速度后,执行步骤205:确定第一移动速度是否大于预设速度阈值。若是,则将该第一移动速度作为最大移动速度,即执行步骤209:作为最大移动速度。
104:若第一移动速度小于预设速度阈值,则根据各个子区域对应的作业量确定平均作业量,根据最大作业量和平均作业量,确定可移动平台的第二移动速度,并将第二移动速度作为可移动平台对作业区域进行作业时的最大移动速度,第二移动速度大于或等于第一移动速度。
其中,根据各个子区域对应的作业量中的最大作业量和平均作业量,确定可移动平台的第二移动速度,包括:若最大作业量和平均作业量的差值与平均作业量的比值小于预设比值阈值,则将第一移动速度确定为可移动平台的第二移动速度;若最大作业量和平均作业量的差值与平均作业量的比值大于预设比值阈值,则根据平均作业量,确定可移动平台的第二移动速度。
例如,根据前文所述,当第一移动速度小于预设速度阈值的时候,可以执行步骤206:确定最大作业量和平均作业量的差值与平均作业量的比值。然后,执行步骤207:确定比值是否大于比值阈值。若是,则认为亩用量的最大值与平均亩用量相差过大,大多数子区域所需的实际亩用量更偏向于平均亩用量,则可以执行步骤208:根据平均作业量,确定可移动平台的第二移动速度,即执行步骤209:作为最大移动速度。若否,则认为亩用量的最大值与平 均亩用量之间相差不大,大多数子区域所需的实际亩用量也比较大,此时根据最大亩用量及最大流量计算出该作业区域的移动速度,即第一移动速度可以作为最大移动速度。
除此以外,还可以通过确定最大作业量和平均作业量之间的差值,当该差值大于差值阈值的时候,则根据平均作业量,确定可移动平台的第二移动速度。若差值小于或等于差值阈值,则可以根据最大亩用量及最大流量计算第一移动速度。
需要说明的是,若第一移动速度等于预设速度阈值,则也可以按照上述方式确定第二移动速度,也可以按照上述方式确定第一移动速度。若比值等于比值阈值,则可以按照上述方式确定第二移动速度,也可以按照上述方式确定第一移动速度。
本申请实施例可以根据作业区域中最大作业量和平均作业量之间的差值的比较,可以剔除由于个别子区域对应的作业量需求极大而导致整个作业区域的作业效率特别低的问题,尤其针对变量喷洒或播撒作业,在满足每个子区域的需求的前提下,又兼顾了作业效率,有效提升了可移动平台的作业能力,解决了可移动平台在变量作业领域中长期存在的问题。
其中,上述根据平均作业量,确定可移动平台的第二移动速度的方式,可以包括:根据平均作业量和预设补偿比例,确定可移动平台的第二移动速度。
其中,该预设补偿比例可以是针对作业量的,也可以是针对移动速度的。
当针对作业量的时候,该确定方式可以是具体的为,根据平均作业量和预设补偿比例,确定可移动平台的第二移动速度,包括:根据平均作业量和预设补偿比例,确定目标作业量;根据目标作业量和可移动平台的最大流量,确定可移动平台的第二移动速度。
例如,根据前文所述,可移动平台可以基于平均作业量,如平均亩用量,在该基础上增加15%-20%的作业量,如亩用量,得到目标作业量,如实际作业的亩用量,基于目标作业量和可移动平台的最大流量,通过上式1)得到第二移动速度,此处就不再赘述。应理解,在利用上式1)确定第二移动速度的时候,其中上式1)中的Vmax为第二移动速度,Mu表示为目标作业量。
当针对移动速度的时候,该确定方式可以是具体的为,根据平均作业量和预设补偿比例,确定可移动平台的第二移动速度,包括:根据平均作业量 和可移动平台的最大流量,确定可移动平台的第三移动速度;根据第三移动速度和预设补偿比例,确定可移动平台的第二移动速度。
例如,根据前文所述,可移动平台可以利用上式1)来确定第三移动速度,在确定第三移动速度中,上式1)中的V max为第三移动速度,Mu表示为平均作业量。从而确定出第三移动速度。在此处基础上,可以在第三移动速度上减少15%-20%的第三移动速度,得到最大的移动速度,并作为第二移动速度。
需要说明的是,本申请的方法也可以直接根据平均作业量和预设补偿比例,确定可移动平台的第二移动速度,并作为最大的移动速度。可以无需执行确定第一移动速度的步骤以及第一移动速度是否大于预设速度阈值等步骤。可移动平台可以直接根据确定的第二移动速度进行作业。以此来满足作业量的需求,同时提高作业效率。
在最大作业量和平均作业量相差较大的时候,以计算的第二移动速度作业并不能满足该作业区域中所有子区域对应的作业量需求,为了更好地满足在作业量需求较大的子区域的作业时,适当减小移动速度。
具体的,若第一移动速度小于预设速度阈值,该方法100还包括:根据各个子区域对应的作业量,确定可移动平台的第四移动速度;若第四移动速度大于或等于最大移动速度,则控制可移动平台以最大移动速度对子区域进行作业;若第四移动速度小于最大移动速度,则控制可移动平台以第四移动速度对子区域进行作业。
如果根据作业区域中的作业量对可移动平台的移动速度进行实时调整,会导致在整个作业过程中由于作业量的变化出现可移动平台频繁加减速的情况。而频繁加减速会带来巨大的能耗损失。因此,本发明实施例在第四移动速度大于或等于最大移动速度时,控制可移动平台以最大移动速度对子区域进行作业,只有在第四移动速度小于最大移动速度时,控制可移动平台以第四移动速度对子区域进行作业。如此,可以保持可移动平台在大多数时候以均匀的速度移动,避免频繁加减速的情况。
例如,根据前文所述,可移动平台可以利用上式1)计算处方图中各个栅格对应的移动速度,其中,针对各个栅格而言,上式1)中的V max为第四移动速度,Mu表示为各个栅格对应的作业量,从而得到各个栅格对应的第四移动速度。可移动平台根据预置好的移动轨迹进行移动的过程中,向移动轨迹上的下一个栅格移动的时候,确定下一个栅格对应的第四移动速度。当第四移动速度 点大于或等于第二移动速度。则可移动平台可以继续以最大移动速度,如第二移动速度,进行作业。否则,则可以可移动平台可以下达控制指令,控制最大移动速度变换为第四移动速度,进行下一个栅格的作业。
需要说明的是,由于下达控制指令存在延时,所以需要提前对后续的移动速度进行确定,然后下达控制指令来作业。
当第四移动速度大于或等于最大移动速度,虽然继续以最大移动速度进行作业,但是如果还是以最大流量进行作业,会导致实际作业量和处方图指示的作业量不符,还会浪费资源,如浪费农药或种子等。为了能够更好地进行作业,以及节约流量,还可以通过调整流量的方式来实现:
具体的,若第四移动速度大于或等于最大移动速度,该方法100还包括:根据第四移动速度对应的子区域的作业量和最大移动速度,确定可移动平台对子区域进行作业时的流量。
例如,根据前文所述,可移动平台可以利用上式1)确定流量:
Figure PCTCN2020127597-appb-000002
此时,可以将该式进行变形,得到flow max为未知数值,即待求取数值。V max等于第四移动速度,Mu等于对应的子区域的作业量。从而确定出可移动平台对子区域进行作业时的流量flow max
可移动平台在得到上述流量后,可以基于该得到的流量,对流量进行控制,如通过控制可移动平台上设置的多个喷嘴的开关来控制喷洒流量,或者,通过控制可移动平台上设置的仓门打开幅度的大小来控制播撒流量。
在一个实施例中,若第一移动速度大于预设速度阈值,可以控制可移动平台以第一移动速度对作业区域进行作业,在作业过程中根据上述方法实时调整流量,以使得可移动平台的实际作业量与处方图指示的作业量相符合。
基于上述相似的发明构思,本申请实施例还提供了一种可移动平台的作业规划方法。如图4所示,本申请实施例提供的该方法400可以由可移动平台执行,或者由可移动平台的控制设备执行。可移动平台可以是无人机,智能移动机器人、智能移动小车等可移动的智能设备。控制设备可以包括遥控器、手机、电机、平板电脑,笔记本电脑中的一种或多种。该方法400包括以下步骤:
