请一并参阅图1至图3,本发明实施方式的云台100的保护方法包括:
S10:在云台电调30进行固件升级时控制所述云台100进入休眠模式;
S20:在所述云台电调30完成固件升级后检测所述云台电调30与所述云台100的处理器12是否通讯正常;
S30:在所述云台电调30与所述处理器12通讯正常时,控制所述云台100进入唤醒模式;和
S40:在所述云台100进入唤醒模式后根据所述云台100在所述云台电调30进行固件升级前的目标姿态调整所述云台100的当前姿态;
其中,当所述云台100进入休眠模式时,所述云台100的电机20的力矩输出为零;当云台100进入唤醒模式时,所述电机20正常工作。
请结合图3,本发明实施方式的云台100的保护装置10包括一存储器11和所述处理器12。所述存储器11用于存储程序代码,所述处理器12用于执行所述存储器11中的程序代码。本发明实施方式的云台100的保护方法可以由本发明实施方式的云台100的保护装置10实现。具体地,当所述程序代码被执行时,可实现S10、S20、S30和S40中的方法。也即是说,当程序代码被执行时,可实现以下操作:
S10:在云台电调30进行固件升级时控制所述云台100进入休眠模式;
S20:在所述云台电调30完成固件升级后检测所述云台电调30与所述云台100的处理器12是否通讯正常;
S30:在所述云台电调30与所述处理器12通讯正常时,控制所述云台100进入唤醒模式;
S40:在所述云台100进入唤醒模式后根据所述云台100在所述云台电调30进行固件升级前的目标姿态调整所述云台100的当前姿态;
其中,当所述云台100进入休眠模式时,所述云台100的电机20的力矩输出为 零;当云台100进入唤醒模式时,所述电机20正常工作。
可以理解,一般的大型云台都有独立的云台电调板,云台电调进行固件升级是比较常见的情况,但在云台电调完成固件升级后,云台电调固件重启时,云台电调会控制云台的电机进行撞限位以完成自检,从而触发云台的规避限位逻辑,导致云台的朝向发生变化,与用户期望不符,用户可能还需要手动操作使得云台返回云台电调进行固件升级前的朝向。
本发明实施方式的云台100的保护方法和云台100的保护装置10,在云台电调30进行固件升级时控制云台100进入休眠模式,直到云台电调30完成固件升级并与云台100的处理器12正常通讯时,才控制云台100进入唤醒模式并根据云台100在云台电调30进行固件升级前的目标姿态调整云台100的当前姿态,如此,可以保证在云台电调30固件升级后,云台100的朝向不乱,云台100可以重新正常使用,不需要手动操作云台100返回云台电调30固件升级前的朝向,没有不友好的细节。
具体地,云台电调30可通过固件升级进行性能提升、BUG修复或者添加新功能等方面的维护。当云台电调30开始进行固件升级时,处理器12控制云台100进入休眠模式。此时,电机20是没有力矩输出的。本发明实施方式中,处理器12在云台电调30完成固件升级后,不会立即控制云台100由休眠模式进入唤醒模式,而是先检测云台电调30与云台100是否通讯正常,当云台电调30与云台100通讯正常时,处理器12控制云台100进入唤醒模式,使得电机20能够正常工作,处理器12再根据云台100在云台电调30进行固件升级前的目标姿态调整云台100的当前姿态。如此,云台100不会由于电机20进行撞限位自检导致朝向发生变化。
需要指出的是,电机20正常工作时,电机20可以响应云台电调30的控制信号并能够具有力矩输出,即云台电调30能够控制电机20的转动,进而调整云台100的姿态,形成姿态闭环。
请参阅图4,在某些实施方式中,在云台电调30进行固件升级时控制所述云台100进入休眠模式的步骤(即S10)前,保护方法还包括:
S50:检测所述云台100的处理器12是否接收到所述云台电调30发送的心跳包;
本实施方式中,是所述处理器12自身检测是否接收到云台电调30发送的心跳包。
S60:在所述云台100的处理器12未接收到所述心跳包时,判断所述云台100的处理器12未接收到心跳包的持续时长是否大于或等于预定时长;和
S70:在所述持续时长大于或等于预定时长时,确定所述云台电调30在进行固件升级。
在某些实施方式中,当程序代码被执行时,可实现以下操作:
S50:检测所述云台100的处理器12是否接收到所述云台电调30发送的心跳包;
S60:在所述云台100的处理器12未接收到所述心跳包时,判断所述云台100的处理器12未接收到心跳包的持续时长是否大于或等于预定时长;和
S70:在所述持续时长大于或等于预定时长时,确定所述云台电调30在进行固件升级。
具体地,在正常情况下(即云台电调30未进行固件升级时),处理器12与云台电调30是实时通讯的,云台电调30会以固定的频率向处理器12发送心跳包。而云台电调30进行固件升级时,云台电调30不会向处理器12发送心跳包。因此,通过检测处理器12是否接收到云台电调30发送的心跳包可以判断处理器12与云台电调30是否处于通讯状态。当处理器12未接收到云台电调30发送的心跳包表明处理器12与云台电调30通讯断开,当处理器12与云台电调30通讯断开一定时间后,可以确定为云台电调30正在进行固件升级。此时,处理器12将控制云台100进入休眠模式。
预定时长的取值可以大于或等于固定频率的倒数。例如,固定频率为5Hz,则预定时长大于或等于0.2s。
类似的,在S20中检测云台电调30与云台100的处理器12是否通讯正常也可以通过上述方式来实现,即:检测处理器12是否接收到云台电调30以固定频率发送的心跳包;在处理器12接收到云台电调30以固定频率发送的心跳包时确定云台电调30与处理器12通讯正常,从而处理器12可以在云台电调30与处理器12通讯正常时,控制云台100进入唤醒模式。
请参阅图5,在某些实施方式中,在云台电调30进行固件升级时控制所述云台100进入休眠模式的步骤(即S10)包括:
S12:在接收到用户输入的升级命令后控制所述云台100进入休眠模式;
其中,所述升级命令用于控制所述云台电调30进行固件升级。
在某些实施方式中,当程序代码被执行以实现在云台电调30进行固件升级时控制所述云台100进入休眠模式的操作时,包括执行以下操作:
S12:在接收到用户输入的升级命令后控制所述云台100进入休眠模式;
其中,所述升级命令用于控制所述云台电调30进行固件升级。
具体地,云台100或云台100的控制端可包括电调固件升级按钮,用户可以通过电调固件升级按钮来触发云台电调30进行固件升级。当用户点击电调固件升级按钮后,上位机或应用程序向处理器12推送升级命令,处理器12根据升级命令控制云台电调30进行固件升级;或者,上位机或应用程序同时向处理器12和云台电调30推 送升级命令,云台电调30根据升级命令进行固件升级。本发明实施方式中,处理器12无需判断云台电调30是否在进行固件升级,只需要在接收到升级命令时控制云台100进入休眠模式即可。
在某些实施方式中,在所述云台电调30完成固件升级后,所述云台电调30在与所述处理器12通讯前控制所述电机20通过撞限位完成自检。
具体地,云台电调30控制电机20进行撞限位完成自检,指的是云台电调30控制电机20转动以将云台100的各个轴的关节角调整至关节角零位。其中,云台100可采用角度传感器(例如电位计、霍尔传感器、光电编码器中的至少一种)测量云台100的各个轴的关节角。以云台100是三轴云台为例进行说明,云台100包括横滚轴、偏航轴和俯仰轴,云台电调30控制横滚电机转动以将横滚轴的关节角调整至关节角零位、或/且控制偏航电机转动以将偏航轴的关节角调整至关节角零位、或/且控制俯仰电机转动以将俯仰轴的关节角调整至关节角零位。本发明实施方式中,云台电调30在自身完成固件升级后而与处理器12通讯前控制电机20进行自检,使得云台100能够回到各个轴的关节角为零位对应的位置,从而有利于后续处理器12根据云台100在云台电调30进行固件升级前的目标姿态来调整云台100的当前姿态。
需要指出的是,在云台电调30完成固件升级后,而云台电调30与处理器12通讯前,云台100仍处于休眠模式,云台电调30对电机20的控制不为姿态闭环,但电机20仍可在云台电调30的控制下完成自检。
请参阅图6,在某些实施方式中,保护方法还包括:
S80:获取所述云台100在所述云台电调30进行固件升级前的目标姿态。
在某些实施方式中,当程序代码被执行时,还可实现以下操作:
S80:获取所述云台100在所述云台电调30进行固件升级前的目标姿态。
具体地,在云台100正常工作过程中,云台100的角度传感器可以时刻检测云台100的姿态,处理器12从角度传感器处获取云台100在云台电调30进行固件升级前一时刻的姿态作为目标姿态,以便于在云台电调30进行固件升级后根据目标姿态来调整云台100的当前姿态,保证云台100的朝向不乱。
请参阅图7,在某些实施方式中,所述云台100具有一个轴或多个轴,获取所述云台100在所述云台电调30进行固件升级前的所述目标姿态的步骤(即S80),包括:
S82:获取所述云台100在所述云台电调30进行固件升级前的每一个轴的目标关节角;
在所述云台100进入唤醒模式后根据所述云台100在所述云台电调30进行固件升级前的目标姿态调整所述云台100的当前姿态的步骤(即S40),包括:
S42:在所述云台100进入唤醒模式后,根据每一个轴的所述目标关节角调整每一个轴的当前关节角。
在某些实施方式中,当程序代码被执行时,可实现以下操作:
S82:获取所述云台100在所述云台电调30进行固件升级前的每一个轴的目标关节角;
S42:在所述云台100进入唤醒模式后,根据每一个轴的所述目标关节角调整每一个轴的当前关节角。
具体地,仍以云台100是三轴云台为例进行说明,云台100可采用角度传感器测量云台电调30进行固件升级前云台100的各个轴的目标关节角,例如横滚轴的目标关节角θ1、偏航轴的目标关节角θ2、俯仰轴的目标关节角θ3。然后,处理器12根据横滚轴的目标关节角θ1、偏航轴的目标关节角θ2、俯仰轴的目标关节角θ3,将横滚轴的当前关节角调整为θ1,将偏航轴的当前关节角调整为θ2,将俯仰轴的当前关节角调整为θ3,以使得云台100的姿态返回到云台电调30进行固件升级前的朝向。
当然,本发明实施方式的云台100的轴的数量除了上述举例的3个轴之外,还可以是1个轴、2个轴、4个轴、5个轴等。
请再次参阅图2,本发明实施方式的云台100包括电机20、云台电调30和上述任一实施方式的保护装置10。所述云台电调30用于控制所述电机20。
本发明实施方式的云台100,在云台电调30进行固件升级时控制云台100进入休眠模式,直到云台电调30完成固件升级并与云台100的处理器12正常通讯时,才控制云台100进入唤醒模式并根据云台100在云台电调30进行固件升级前的目标姿态调整云台100的当前姿态,如此,可以保证在云台电调30固件升级后,云台100的朝向不乱,云台100可以重新正常使用,不需要手动操作云台100返回云台电调30固件升级前的朝向,没有不友好的细节。
