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。
本示例实施方式中首先提供了一种农业植保无人机。参考图1以及图2所示,该农业植保无人机100可以包括动力系统110、飞行控制器120以及无线通信装置130。
在本公开的一种示例实施方式中,动力系统110可以用于给无人机提供飞行动力;例如,该动力系统110可以是包括电机、电调、螺旋桨以及电池的电动机等;其次,飞行控制器120可以与动力系统110电连接,用于控制所述动力系统调节飞行姿态;例如,该飞行控制器例如可以为CPU或者MCU等等;进一步的,无线通信装置130可以与飞行控制器电连接,并且,飞行控制器120可以通过无线通信装置130与控制终端210通信连接。其中,该控制终端例如可以包括农业植保无人机的遥控器、移动终端、地面基站以及后台服务器等等,本示例以控制终端为农业植保无人机的遥 控器为例进行说明。
在本公开的一种示例实施方式中,无线通信装置130将控制终端210发送的用户作业信息的更新数据包,发送给飞行控制器;当飞行控制器120接收到该用户作业新的更新数据包后,根据所述用户作业信息的更新数据包,更新本地存储(例如可以是存储在植保无人机的内存系统中)的用户作业信息;进一步的,当用户作业信息更新后,所述飞行控制器120可以根据更新后的本地存储的用户作业信息,确定是否进入锁定模式。
上述农业植保无人机,一方面,在无人机不用进入锁定模式的情况下,直接进入作业模式,解决了现有技术中需要人工进行作业引起的作业效率较低且作业效果较差的问题;另一方面,使得用户可以在控制终端将植保无人机的待作业信息布置完成再发送至飞行控制器,避免了用户需要直接在飞行控制器中布置飞行作业导致作业布置流程较为繁琐的问题,提高了作业信息的布置效率;再一方面,使得植保无人机可以在更新后的用户作业信息满足预设条件(例如,待作业的亩数大于可以作业的亩数)时,确定无人机进入锁定模式,避免了用户对植保无人机的过度使用,进而减少了经济损失;同时,当进入锁定模式以后,用户可以通过采用继续付费的模式进行解锁,避免了需要一次性支付较高额度费用导致的购买困难较大,进而使得无人机普及增速得不到保障,从而某程度上导致农业信息化速度较慢的问题。
在本公开的一种示例实施方式中,判断植保无人机是否进入锁定模式例如可以包括:一方面,可用作业亩数:根据喷洒面积计量收费,喷洒流量计获取有效的喷洒亩数面积;例如,可用作业亩数小于更新的用户作业信息中的需要喷洒的亩数,则进入锁定模式;另一方面,可用飞行时长:根据购买使用植保无人机的时长进行结算,时间到了就停止使用;例如,可用飞行时长小于更新的用户作业信息中的需要的飞行时长,则进入锁定模式;再一方面,喷洒流量的亩用量:根据喷洒喷头流出的用量,计算喷洒总流量等;例如,可喷洒流量的亩数小于需要喷洒的亩数,则进入锁定模式;进一步的,可用的起降次数:根据有效的起降次数,计算起降次数最大值限制等;例如,可以用的起降次数小于需要的起降次数,则进入锁定模式;更进一步的,按特定时间结算:以每月/每周/每天/每小时的充值时间段结算;例如,喷洒当天(月/周或者小时数)的可用时长小于需要的时长,则进入锁定模式等等。
在本公开的一种示例实施方式中,为了更新本地存储的用户作业信息,飞行控制器120还可以用于在起飞之前,向所述控制终端210发送包括用户作业信息的更新数据包的请求指令;当控制终端210接收到请求指令后,通知用户对待作业信息进行布置;此处需要说明的是,可以布置任一项上述任务,然后通过换算的方式,得到其他的任务;例如,可以通过布置需要喷洒的亩数,然后飞行控制器可以通过该需要喷洒的亩数,得到需要的飞行时长、需要的喷洒流量以及需要的起降次数等等。更进一步 的,当飞行控制器120接收到控制终端210响应上述请求指令发送的用户作业信息的更新数据包后,可以利用该用户作业信息的更新数据包更新本地存储的用户作业信息。
在本公开的一种示例实施方式中,飞行控制器120还可以用于若所述请求指令的请求时间或次数超过预设条件,则直接进入锁定模式。例如,当上述请求指令的请求时间超过预设时长(控制终端长时间没有响应,例如,5min没有响应等等)或者次数超过预设次数(例如发送了五次请求指令,但是控制终端均没有响应等),则可以直接控制植保无人机进入锁定模式。通过该方法,可以进一步的保护无人机的安全。
在本公开的一种示例实施方式中,飞行控制器120还可以用于若所述请求指令的请求时间或次数超过预设条件,则根据本地存储的当前用户作业信息,确定是否进入锁定模式。例如,当控制终端210未响应是,当本地存储的当前用户待作业信息满足植保无人机的可作业条件时,可以控制该植保无人机进入作业模式;不满足可作业条件时,控制该植保无人机进入锁定模式。
在本示例实施方式中,所述飞行控制器还可以用于若更新后的本地存储的用户作业信息的剩余值小于等于预设值,则不进入所述锁定模式。例如,剩余亩数小于等于预设亩数(可以作业亩数),则可以不进入锁定模式(进入作业模式);进一步的,若更新后的本地存储的用户作业信息的剩余值大于预设值,则进入所述锁定模式。例如,剩余亩数大于预设亩数,则可以进入锁定模式。
在本示例实施方式中,所述飞行控制器还可以用于:实时获取当前的用户作业信息;根据所述当前的用户作业信息,更新本地存储的用户作业信息。例如,用户可以根据当前需要作业的亩数实时的更新遥控器中的待作业信息,然后遥控器可以将该待作业信息实时的发送至无线通信装置;无线通信装置再将该待作业信息发送至飞行控制器,以使飞行控制器实时的更新存储的用户作业信息。通过该方式,可以降低无人机的起降次数,提高作业效率;同时也可以减少由于起降次数过多对无人机的损伤。
在本示例实施方式中,为了可以对植保无人机进行正常使用,还需要对该植保无人机进行激活。其中:所述控制终端还用于接收用户的激活请求,根据所述激活请求生成激活指令,并将所述激活指令发送至飞行控制器;所述飞行控制器还用于根据所述激活指令,激活所述无人机。进一步的,所述控制终端通过与所述无人机对应的秘钥对所述激活指令加密,并将加密后的激活指令发送至飞行控制器。更进一步的,所述飞行控制器通过对加密后的所述激活指令进行解密,并根据解密后的所述激活指令激活所述无人机。例如,值保无人机在出厂时会写入一机一密,此一机一密可为对称密钥,也可为非对称密钥,并且存储服务器的公钥或对称密钥。用户220可以通过控制终端210发送激活请求给服务器230,服务器230根据激活请求,生成激活指令,并由服务器230进行签名加密之后,将该加密后的激活指令发送给控制终端210;控 制终端210再将该激活指令通过无线通信模块130发送给飞行控制器120;当飞行控制器120校验服务器的命令的签名之后,若合法,则进行激活操作。通过使用该方式,避免了由于恶意的激活对无人机造成的损害,进一步的提升了无人机的安全同时也提升了用户在使用过程中的安全。
在本示例实施方式中,为了便于用户在消费到一定程度后,可以有更好的用户体验,还可以对无人机进行解锁。其中:飞行控制器还用于:获取已作业信息的总量,其中,所述已作业信息的总量为所述农业植保无人机的历史已作业信息量之和;根据所述已作业信息的总量,确定是否解除所述锁定模式。进一步的,飞行控制器还用于若所述已作业信息的总量大于预设量,则解除所述锁定模式;其中,用户作业信息可以包括作业里程、作业面积、作业时间、作业药量、飞行时间、起飞次数以及充值金额。例如,可以获取历史的历次已成功作业的信息;然后计算历次已成功作业的信息的总量之后;当该已成功作业的信息的总量大于预设量时(例如,已成功作业的信息的总量为15000亩,预设量为12000亩),则可以接触该植保无人机的锁定模式。
在本示例实施方式中,飞行控制器还可以用于在所述锁定模式时,停止控制所述农业植保无人机的作业部件进行作业;并停止剩余的作业计划;其中,作业部件可以包括水泵、喷头以及播撒器等等;例如,可以控制水泵停止泵水、关闭喷头播撒器等等;进一步的,在锁定模式时,控制所述动力系统不产生起飞动力;更进一步的,在所述锁定模式时,控制所述农业植保无人机立即返航;例如,当农业植保无人机在工作过程中进入锁定模式时,可以立即停止作业部件的作业,并立即返航;更进一步的,在所述锁定模式时,发送锁定的提示信息给所述农业植保无人机的遥控器;例如,飞行控制器可以在植保无人机进入锁定模式时,生成一锁定状态的信息发送至遥控器,然后遥控器将该信息呈现给用户以使用户进行后续处理。
本公开还提供了一种农业植保无人机的控制方法。参考图3所示,该控制方法可以包括步骤S310、步骤S320以及步骤S330。其中:
在步骤S310中,接收控制终端发送的用户作业信息的更新数据包。

进一步的,为了更新本地存储的用户作业信息,该控制方法还可以包括:在起飞之前,向所述控制终端210发送包括用户作业信息的更新数据包的请求指令;当控制终端210接收到请求指令后,通知用户对待作业信息进行布置;此处需要说明的是,可以布置任一项上述任务,然后通过换算的方式,得到其他的任务;例如,可以通过布置需要喷洒的亩数,然后飞行控制器可以通过该需要喷洒的亩数,得到需要的飞行时长、需要的喷洒流量以及需要的起降次数等等。更进一步的,当飞行控制器120接收到控制终端210响应上述请求指令发送的用户作业信息的更新数据包后,可以利用该用户作业信息的更新数据包更新本地存储的用户作业信息。
