Embodiment Construction

[0040] Next, preferred embodiments of the present invention will be described with reference to the drawings.

[0041] Figure 1 schematically illustrates the structure of the overall system forming the basis of the mechanical function changing system according to the invention. In this embodiment, a hydraulic excavator is shown as an example of the machine in the figure. As elements forming this entire system, a manufacturer 2 that produces and sells hydraulic excavators 1 and a user 3 that uses hydraulic excavators are shown in the figure.

[0042] In the above overall system, the hydraulic excavator 1 is used at a construction site or its vicinity. Manufacturer 2 and user 3 are located at locations separated from hydraulic excavator 1 spatially or geographically. In this entire system, IT (Information Technology) is actively used to connect the hydraulic excavator 1, the manufacturer 2, and the user 3. Internet 11, indoor LAN 12, and communication lines using telecommunic...

Abstract

A system comprising a hydraulic shovel (1) and a base station (16). The hydraulic shovel (1) is placed in a work site and provided with a rewritable memory (402) where a control program needed for control of a work machine is stored, a CPU (401) for reading the control program from the memory (402) and executing the program, and a communication device (42). The base station (16) comprises a communication device (16a), a management server (17) for identifying the number of the hydraulic shovel and communicating information with a control unit, and a database (18) which is managed by the management server (17) and in which control programs for the respective types of hydraulic shovels used adapted to the hydraulic shovel are stored. When the attachment of the hydraulic shovel is exchanged, information is communicated with the management server of the base station so as to rewrite the control program and alter the data stored in a storage and to do a work suitable for the exchanged attachment.

Description

technical field [0001] The present invention relates to a function changing system and a base station of a working machine, and particularly relates to a function changing system of a processing machine, which can utilize a base station equipped by a company manufacturing the machine or another company related to the machine The information sent from the central server of the machine rewrites the control program or data stored in the storage device, so that when the working surface or attachments of construction machinery such as hydraulic excavators are changed, the work suitable for the changed components can be performed. In addition, the present invention relates to a base station for managing a large number of work machines. Background technique [0002] As references disclosing conventional machines, there are Japanese Unexamined Patent Publication (Kokai) No. 7-166582 and Japanese Unexamined Patent Publication (Kokai) No. 6-20127. [0003] Japanese Unexamined Patent ...
