摘要：
A function changing system of construction machinery includes a hydraulic excavator and a base station. The hydraulic excavator is deployed at a construction site and is provided with a rewritable memory storing control programs and/or data required for control of the machinery, a CPU for reading out the control programs from the memory and executing them, and a communications device The base station is provided with a communications device, a center server for identifying the serial number of the hydraulic excavator and transferring information with the control unit, and a database managed by the center server and storing control programs corresponding to the hydraulic excavator. When changing or switching an attachment of the hydraulic excavator, information is transferred with the center server of the base station and the control programs or data stored in the storage unit are rewritten to enable work suited to the changed part.
