Abstract: The present invention discloses a control device and method for engine coupling of an excavator. The control device includes a main controller, a switch control unit and an engine controller that are electrically connected with one another; by means of a bus, and an electronic monitor, an emergency stop switch and an emergency mode relay are connected onto the man controller. The intelligent start-stop control is achieved by start-stop of controller coupling, and meanwhile, the purpose of uninterrupted control power supplied to a system key switch during flame-out is achieved by coupling shutdown via the controllers; and when the controllers fail, a contact state of a safety relay can be converted to switch a power supply and start a loop, and a start-stop loop can be switched from coupling control to direct control by means of the emergency mode relay, thereby improving the reliability of a start-stop control system.

Abstract: A landscape generation system includes at least one landscape generation module, each landscape generation module includes a base frame, and N telescopic units connected with the base frame and arranged in an array; each telescopic unit includes a landscape creation part, and a driving mechanism mechanically connected with the landscape creation part and the base frame; and the driving mechanism drives, during operation, the landscape creation part to move within a preset interval along a target direction to adjust a distance between an end face of the landscape creation part and the base frame, and stops and locks the landscape creation part at any position in the preset interval so as to generate part of a preset landscape. A landscape can be generated by the landscape generation system to meet a user's needs for landscapes in different occasions and enhance the user experience.

Abstract: A landscape generation system includes M landscape generation modules. Each landscape generation module includes N telescopic units and a control module, where each telescopic unit includes a landscape creation part, and a driving mechanism mechanically connected with the landscape creation part and the base frame and configured to, when working, drive the landscape creation part to move within a preset interval along a target direction and stop and lock the landscape creation part at any position in the preset interval; and the control module is configured to, when working, perform receiving a first instruction that corresponds to a preset landscape, and driving a plurality of driving mechanisms in the M landscape generation modules based on the first instruction to run to move M×N landscape creation parts to respective target positions, thereby generating the preset landscape.
