在一些可行的实施方式中,中央控制器30与无人机飞行控制器20连接,同时中央控 制器30也可以分别与数据采集终端40a至数据采集终端40n连接。中央控制器30可以通过通讯接口实现与无人机飞行控制器20和数据采集终端40a至数据采集终端40n之间的直接通讯(如下发控制指令),传输速度快。这里的通讯接口可以为并行通讯接口或者串行通讯接口,比如,串行总线(universal serial bus,USB)通讯接口,千兆以太网(gigabit ethernet,GE)通讯接口,异步传输标准接口(recommended standard 232,可以简称为RS232通讯接口)或者其它通讯接口。其中,RS232通讯接口也可以称为EIA-RS232(electronic industries association-recommended standard 232)通讯接口或者232通讯接口。可选的,无人机飞行控制器20、中央控制器30以及数据采集终端40a至数据采集终端40n之间也可以进行无线通讯,可减少通信接线,降低安装要求,适用性更强。需要说明的是,无人机飞行控制器20、中央控制器30以及数据采集终端40a至数据采集终端40n之间的连接关系具体可根据实际应用场景确定,在此不做限定。
通常来说,无人机飞行控制器20中可以包含主控单元、惯性测量单元(iertial measurement unit,IMU)、全球定位***(global positioning system,GPS)指南针单元(这里的GPS指南针单元可以包含GPS单元和指南针单元)、发光二极管(light emitting diode,LED)指示灯单元等部件。该主控单元是无人机飞行控制器20的核心,可以通过主控单元将惯性测量单元、GPS指南针、舵机和遥控接收机等设备接入无人机飞行控制器20中,从而实现无人机10的自主飞行功能。此外,主控单元也可以记录无人机10的飞行数据,该主控单元还可以通过通讯接口(如USB接口)调节飞行参数。该惯性测量单元一般可以包含3轴加速度计、3轴角速度计和气压高度计,可以通过其3轴加速度计、3轴角速度计和气压高度计来高精度感应无人机10的飞行姿态、飞行角度、飞行速度以及飞行高度。该GPS指南针单元可以用于精确确定无人机10的方向及经纬度,从而可以实现无人机失控保护自动返航以及无人机精准定位悬停等功能。LED指示灯单元可以用于实时显示无人机10的飞行状态。因此,中央控制器30可以向无人机飞行控制器20下发飞行控制指令,以使无人机飞行控制器20通过其中的主控单元、惯性测量单元、GPS指南针单元以及LED指示灯单元控制无人机10的飞行,实现无人机10全方面巡视电站(如上述光伏电站2)。
