The invention provides an arm support telescopic sensing system and engineering machinery, a rolling mechanism is mounted on the cavity wall of a hollow cavity, and a guide groove is defined by the rolling mechanism and a suspension arm; the telescopic mechanism comprises a telescopic frame with a rolling plane, a telescopic driving piece and a locking assembly installed on the telescopic frame, the locking assembly is used for locking or unlocking the telescopic frame and the suspension arm, the telescopic driving piece is used for driving the suspension arm to stretch out and draw back through the telescopic frame, the telescopic frame can be matched with the guide groove in a guiding mode, and the rolling plane is used for being matched with the rolling mechanism in a rolling contact mode; the controller is configured to control the locking assembly to lock the telescopic frame and the suspension arm under the condition that the telescopic frame stretches out and draws back in place relative to the suspension arm, and output a locking signal under the condition that the telescopic frame and the suspension arm are locked in place; acquiring preset coding information and coding combination information of the suspension arm; and according to the code combination information and the preset code information, outputting a suspension arm code of the suspension arm. Through the suspension arm, the rolling mechanism, the telescopic mechanism and the controller, the telescopic operation efficiency of the boom can be improved, and the use safety risk can be reduced.
