  "textContent": "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; the main controller is connected to the switch control unit and the engine controller by means of a bus, respectively; and an electronic monitor, an emergency stop switch and an emergency mode relay are connected onto the man controller. The separate control for power supply control and engine start-stop is achieved by the independent design of a power-on switch and a start-stop switch, intelligent start-stop control is further 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.",
