摘要:
A working machine maintenance system having a plurality of working machines. A center server is provided that manages maintenance on the plurality of working machines by engaging in data exchange through bidirectional communication with each of the plurality of working machines via a communication line. The working machines each include an operation data storage device, an operation device operated to enter a maintenance work completion, a data transmission device, a data reception device, and a display device at which the maintenance information is displayed. The center server includes a data reception device that receives the operation data, the maintenance work completion data, and the maintenance data that have been transmitted, an operation database in which the operation data are stored, a maintenance database, a calculation device that calculates maintenance timing. and a data transmission device that transmits data related to the maintenance information.

Provided is a communication system for working machines, which makes it possible to transmit desired messages from sites, where the working machines are arranged, to their corresponding work administration centers at timings as needed. When a mail switch 10 arranged on a working machine 7 is operated to send information to a server 1, a terminal user-company identification unit 14 identifies, on the basis of a terminal information database 18, a user to which the information so received is to be sent. A user-company-dependent mail selection unit 15 selects customer information 19a on the user from a customer database 19. At a transmission mail creation unit 16, a corresponding new message 16a is created. The mail is then transmitted from a mail output unit 17. In this manner, a desired message can be sent from each working machine 7 at a remote location to the corresponding user at a timing as needed.

A method and system for managing a construction machine and processing apparatus therefor includes a controller 2 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 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.
摘要:
A hydraulic excavator periodically measures its current location at predetermined time intervals by the GPS device in an inoperative state where its engine key is in the off position and sends the current location data and time data to a management server by a main controller and communicator. The management server receives the periodically sent location data at its communicator and successively stores it in its memory. The current location data and the measurement time data to provide a location confirmation service by a location information provider. Changes in location can be confirmed on a map, the movement of the hydraulic excavator can be tracked, and assistance can be given for confirmation of location and prevention of theft.

Assessment information needed to calculate a used vehicle assessment value of a hydraulic excavator 10 is input to a portable telephone 20 and is then transmitted from the portable telephone 20. The transmitted assessment information is received at a manufacturer's base station 40 at a remote location. The used vehicle assessment value of the hydraulic excavator 10 is calculated based upon the received assessment information, and history information and operation information on the hydraulic excavator 10 read out from an operation information database 43 and a history database 42 in correspondence to an ID number assigned to the hydraulic excavator which is included in the assessment information.
摘要:
A method and system for managing a construction machine whereby working time for each of different parts of a hydraulic excavator is measured. Measured data is stored in a memory of a controller and then transferred to a base station computer via satellite communication to be stored in a database. At each repair/replacement of a part in each hydraulic excavator, the base station computer calculates, based on the operation data, a replacement time interval of the part on the basis of the working time per section to which the part belongs, and then stores and accumulates it. The base station computer also reads the stored data for each hydraulic excavator, determines, for each part, a replacement rate of the part having a substantially equal replacement time interval, and calculates a target replacement time interval of the part in accordance with the replacement time interval corresponding to a maximum replacement rate.
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.
摘要:
The position of a working machine is detected, a position signal representing the detected position is transmitted, the position signal is received, management information relating to the working machine is calculated based on the received position signal, and the calculated management information is transmitted to the working machine. Example of management information is type of attachment depending on soil quality, and weather forecasts.

摘要:
A maintenance system of a hydraulic excavator (11) is provided with a maintenance monitoring device (21), a maintenance management server (12) for managing trouble information and operating information for each working machine, a model information server (13), and a service personnel mobile terminal (14) connected to one another through the Internet (15). When trouble occurs in the hydraulic excavator, the maintenance system (21) transmits trouble information to the maintenance management server (12), and the maintenance management server (12) transmits information on occurrence of trouble to the mobile terminal (14) and displays it on a display unit. This system manages the maintenance manuals and other data for each model in a model information database separate from the maintenance database and correlates the two databases based on the model data.
