ガバナレバーの遠隔操作装置。 Engine speed command means for outputting the engine speed commanded by the driver as an analog signal; and a pulse converter for converting the analog output signal from the engine speed command means into a pulse signal according to the output. is installed in the driver's cabin, while
The engine room contains the engine and the governor lever that controls the engine's rotation speed.
An actuator for operating the governor lever is provided, and the actuator includes a mechanical operation section that mechanically drives the governor lever, a power controller that instructs the mechanical operation section to operate the governor lever, and a power controller that detects the current engine rotation speed. A feedback signal output section that outputs an analog feedback signal, an analog conversion section that returns the pulse signal from the pulse converter to an analog command signal, and an analog conversion section that outputs the analog command signal from the analog conversion section and the feedback signal output section and a calculation processing section that calculates a governor lever operation amount for obtaining a commanded engine rotation speed based on a feedback signal and outputs it to the power controller.
Governor lever remote control device.
