Disarmed by auto preflight disarming自动上锁

使用px4的无人机，解锁后一段时间（10秒）没有起飞，就会自动上锁

可以修改

PX4-Autopilot/src/modules/commander/commander_params.c

230行的位置

/*** Time-out for auto disarm if not taking off** A non-zero, positive value specifies the time in seconds, within which the* vehicle is expected to take off after arming. In case the vehicle didn't takeoff* within the timeout it disarms again.** A negative value disables autmoatic disarming triggered by a pre-takeoff timeout.** @group Commander* @unit s* @decimal 1* @increment 0.1*/
PARAM_DEFINE_FLOAT(COM_DISARM_PRFLT, 10.0f);

如果10s太短，可以将 10.0f 改成较大的值
