System for changing function of work machine and base station

A function changing system of machinery characterized by being comprised of:

• machinery deployed at a construction site and provided with a rewritable storage unit storing control programs and/or data required for control of work operation, a control unit for reading out at least control programs from the storage unit to execute the work operation, and a first communications device and
• a base station provided with a second communications device, a center server for identifying a serial number of said machinery and transferring information with said control unit, and a database managed by that center server and storing basic control programs and data each model of machinery and control programs and data for operation of said machinery;
• wherein
• said control unit of said machinery and said center server of said base station are configured to transfer information with each other based on two-way communication through said first and second communications devices and a communications line;
• when it is necessary to change control programs and/or data stored in said storage unit of said machinery, said center server transmits the control programs and/or data to be changed to said control unit of said machinery;
• and
• when receiving said control programs and/or data, said control unit rewrites the stored content of said storage unit by the received content.

• machinery deployed at a construction site and provided with a rewritable storage unit storing control programs and/or data required for control of work operation, a control unit for calling up at least control programs from the storage unit to execute the work operation, and a first communications device, and
• a base station provided with a second communications device, a center server for identifying a serial number of the machinery and transferring information with the control unit, and a database managed by that center server and storing basic control programs and data for each model of machinery and control programs and data for operation of the machinery, wherein
• said center server of said base station transmits information to said control unit of said machinery through said first and second communications devices and a communications line;
• when it is necessary to change control programs and/or data stored in said storage unit of said machinery, said center server transmits the control programs and/or data to be changed to said control unit of said machinery;
• and
• when receiving said control programs and/or data, said control unit rewrites the stored content of said storage unit by the received content.

A base station for managing individually or all together the work capabilities of a large number of machinery deployed at different construction sites, said base station characterized by being provided with:

• a communications device for communicating with the communications device provided at each of the large number of machinery;
• a center server for identifying the serial number of each of said large number of machinery and transferring information with the control unit of said machinery through said communications device;
• and
• a database managed by said center server and storing basic control programs and data for each model of said machinery and control programs and data for operating said machinery.
