Remote control system and engineering machinery

The invention proposes a remote control system applied to engineering machinery, which comprises a remote control and a controller connected with an indication device, wherein the remote control comprises an operation unit which correspondingly controls a plurality of execution components of the engineering machinery; the remote control is used for generating and sending first trigger information comprising the identification information of the operation unit; and the controller is used for controlling the indication device on the engineering machinery to indicate the execution component corresponding to the identification information or the controlled action of the execution component according to the identification information of the operation unit after the first trigger information is received. The invention also provides engineering machinery. According to the remote control system, the remote-control convenience of each execution component in the engineering machinery can be improved.
