TOPICS: generator_status

Fields

参数名	类型	Unit [Frame]	Range/Enum	描述
timestamp	uint64			time since system start (microseconds)
status	uint64			Status flags
battery_current	float32	A		Current into/out of battery. Positive for out. Negative for in. NaN: field not provided.
load_current	float32	A		Current going to the UAV. If battery current not available this is the DC current from the generator. Positive for out. Negative for in. NaN: field not provided
power_generated	float32	W		The power being generated. NaN: field not provided
bus_voltage	float32	V		Voltage of the bus seen at the generator, or battery bus if battery bus is controlled by generator and at a different voltage to main bus.
bat_current_setpoint	float32	A		The target battery current. Positive for out. Negative for in. NaN: field not provided
runtime	uint32	s		Seconds this generator has run since it was rebooted. UINT32_MAX: field not provided.
time_until_maintenance	int32	s		Seconds until this generator requires maintenance. A negative value indicates maintenance is past-due. INT32_MAX: field not provided.
generator_speed	uint16	rpm		Speed of electrical generator or alternator. UINT16_MAX: field not provided.
rectifier_temperature	int16	degC		The temperature of the rectifier or power converter. INT16_MAX: field not provided.
generator_temperature	int16	degC		The temperature of the mechanical motor, fuel cell core or generator. INT16_MAX: field not provided.
