CONSTRUCTION MACHINE MANAGING METHOD AND SYSTEM, AND ARITHMETIC PROCESSING DEVICE |
摘要 |
<p>A controller 2 is mounted on a hydraulic excavator 1 working in fields. An operating time for each of an engine 32, a front 15, a swing body 13 and a travel body 12 is measured and stored in a memory of the controller 2. The measured data is transferred to a base station computer 3 through satellite communication, a FD, etc. and stored in a database 100 inside the base station computer 3. The base station computer 3 reads, per hydraulic excavator, the data stored in the database 100 and then prepares and outputs a distribution graph of the number of operated machines with respect to the working time (engine running time) of the hydraulic excavator. While looking at the distribution graph, a machine maker estimates the number of hydraulic excavators to be renewed and estimates the sales quantity of hydraulic excavators, thereby setting up a production plan of hydraulic excavators. It is hence possible to precisely estimate the sales quantity of construction machines and to set up an adequate production plan of construction machines. <IMAGE></p> |
