The embodiment of the invention provides a
wireless remote controller,
engineering machinery and a
wireless remote control system, and relates to the field of
engineering machinery. The
wireless remote controller comprises a display module, a key module, a
signal transmission module and a
processing module; the display module, the key module and the
signal transmission module are electrically connected with the
processing module; the
signal transmission module is used for receiving working state information sent by the
engineering machinery; the key module is used for receiving
user input information; the
processing module is used for generating a
wireless control instruction according to information input by a user, and the signal transmission module is further used for sending the
wireless control instruction to the engineering
machine. The processing module is further used for generating display information according to the working state information and the
user input information, and the display module is used for displaying the display information. The wireless remote controller, the engineering machinery and the wireless
remote control system can reflect the operation condition of the equipment, and do not provide accurate reference for operators, so that the engineering machinery can be effectively controlled, and accurate operation is ensured.
