所述固定值包括第一固定值和第二固定值,第一固定值和第二固定值不同,所述第一固定值大于所述第二固定值。在一种可能的场景中,考虑到精度较低的驱动模块可能未配置有关闭功能或者基于某些考虑并未关闭驱动模块,则在关闭所述PWM模块且未关闭所述驱动模块的情况下,从所述电机的三相输入端处测得的相电压的值基本保持在所述第一固定值,所述第一固定值的大小与实际阻容参数有关,所述第一固定值大于零。在另一种可能的场景中,精度较高的驱动模块可能配置有关闭功能,则在关闭所述PWM模块和所述驱动模块之后,从所述电机的三相输入端处测得的相电压的值基本保持在所述第二固定值,所述第二固定值为零。

由于在所述可移动平台的电机开始起转前,当所述可移动平台的预设接口不存在插入事件时,所述可移动平台随时可能通过油门通道发送非0的油门信号,因此所述电调保持与所述油门通道相关的部件处于工作状态,以便所述电调可以随时响应通过所述油门通道发送的油门信号。
其中,在所述第二功耗模式下,所述可移动平台可以控制所述电调关闭与所述电机的驱动事件相关的部分部件以及与油门通道相关的部件。
示例性的,上述内容提到,在所述可移动平台的电机还未起转之前,所述可移动平台可以通过向电调发送控制信号,以控制所述电调至少关闭与所述电机的驱动事件相关的部分部件,其中,所述控制信号还包括通过通信通道发送的第二信号。作为例子,所述通信通道可以是串口通信信道,所述电调可以通过所述串口通信通道上报自身的状态,比如当电调检测到相关故障,如电调硬件故障,电机故障等,可以通过所述串口通信信道告知控制系统,让控制系统做相应的保护逻辑;当然,所述通信通道 也可以是其他通信通道,本实施例对此不做任何限制。
在所述第二功耗模式下,或者说在所述可移动平台的电机开始起转前且所述可移动平台的预设接口存在插入事件的情况下,可移动平台不会通过油门通道发送油门信号,则所述可移动平台可以通过所述通信通道向所述电调发送第二信号,所述电调响应于所述第二信号关闭与所述电机的驱动事件相关的部分部件以及与油门通道相关的部件,从而有利于节省所述电调的功耗,提高可移动平台的续航能力。
其中,在关闭所述与油门通道相关的部件之后,在所述电调的油门接口处测得的数字信号为0或1。在一个例子中,所述油门接口可以是SPI接口;当然,也可以是其他接口类型,本实施例对此不做任何限制。

在关闭与所述电机的驱动事件相关的部分部件时,针对于所述第一部件,所述电调中的MCU芯片可以通过所述预设通信接口向所述第一部件发送配置指令,所述配置指令用于配置所述部件的寄存器的参数以关闭所述部件;针对于所述第二部件,所述电调可以关闭第二部件的时钟,以实现关闭所述第二部件。
在关闭与油门通道相关的部件时,所述电调也可以通过关闭与油门通道相关的部件的时钟,以实现关闭所述与油门通道相关的部件;其中,所述与油门通道相关的部件集成在所述MCU芯片内部。其中,所述与油门通道相关的部件包括油门通信接口。
在一些实施例中,为了进一步节省功耗,在第一功耗模式下,可以控制所述电调关闭除以下部件之外的其他部件:与所述油门通道、所述通信通道和电调灯相关的部件,即并不限于只关闭PWM模块、ADC模块、PGA模块和/或驱动模块等,可以关闭除上述部件(与所述油门通道、所述通信通道和电调灯相关的部件)之外的所有部件,以进一步节省所述电调的功耗。
在第二功耗模式下,可以控制所述电调关闭除以下部件之外的其他部件:与所述通信通道和电调灯相关的部件,即可以关闭除上述部件(与所述通信通道和电调灯相关的部件)之外的所有部件,以进一步节省所述电调的功耗。
在一示例性的实施例中,以所述可移动平台为无人机为例,无人机飞行时,是由飞行控制系统通过油门通道发送油门信号给电调,电调根据油门信号去控制电机加速或者减速。飞行控制系统和电调之间也是有串口通信通道,当电调检测到相关故障,如电调硬件故障,电机故障等,都会通过所述串口通信通道告知飞行控制系统,让飞行控制系统做相应的保护逻辑。
当无人机静止在地面时,所述无人机通过油门通道发送给电调的油门信号(第一信号)是0,表示电调此时不需要控制电机运转,电机处于静止状态。这种情况下,无人机进入第一功耗模式,电调只需要保证与飞行控制系统之间的串口通信通道、油门通道以及所述电调的电调灯正常运行即可,可以关闭与所述电机的驱动事件相关的控件,如ADC(模数转换)外设、PWM(脉冲宽度调制)外设、PGA(可编程增益放大器)外设、driver(驱动)模块等。当无人机需要起飞时,所述无人机会重新发送油门信号(该油门信号非0)给电调,则所述无人机退出第一功耗模式,电调重新打开相关外设,进入正常模式,控制电机起转。
在用户将无人机的USB接口插上usb数据线拷取数据或者升级固件时,这种情况下,所述无人机可以进入第二功耗模式。在这种场景中,电调不用响应通过油门通道发送的油门信号,即除了关闭与所述电机的驱动事件相关的部件外,还可以将与油门通道相关的部件关闭。在无人机的USB接口存在插入事件时,所述无人机进入第二功耗模式,所述无人机通过串口通信通道发送通信信号(第二信号)告知电调将不用的功能关闭,以减少功耗,所述电调关闭与所述电机的驱动事件相关的部分部件以及与油门通道相关的部件。当用户拔出usb数据线后,所述无人机退出第二功耗模式,可以先开启与油门通道相关的部件,如果此时无人机通过油门通道向电调发送油门信号(该油门信号为0),则进入第一功耗模式,所述电调不开启与所述电机的驱动事件相关的部分部件;如果无人机需要起飞,比如通过油门通道向电调发送油门信号(该油门信号非0),则进入正常模式,所述电调开启相关外设(如与所述电机的驱动事件相关的部分部件),控制电机运转。
