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.

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.

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.

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.

A security system of a construction machine of the present invention has a construction machine, a base station and a communication device. The construction machine comprises a data sending and receiving portion for sending first information, a storage portion for storing received information, and a control portion for controlling an operation of the construction machine. The base station receives the first information from the data sending and receiving portion of the construction machine and sends second information to the construction machine and manages the construction machine. It is configured so that the communication device is connected to the base station through a communication network and can send third information to the construction machine through the base station.
摘要:
Hydraulic excavators 1 working in fields each include a controller 2, and an operating time is measured for each of an engine 32, a front 15, a swing body 13 and a track body 12. The measured data is stored in a memory of the controller 2, transferred to a base station computer 3 through satellite communication, an FD, etc., and stored in a database 100 of the base station computer 3. In the base station computer 3, the data stored in the database 100 is read out for each of the hydraulic excavators to obtain a value of an index (e.g., a travel ratio) regarding the state of use of a particular one of the hydraulic excavators and a distribution of the number of operated hydraulic excavators of the same model as the particular hydraulic excavator with respect to the index. The index value and that distribution are compared with each other to determine whether the particular hydraulic excavator is an optimum model. It is therefore possible to make an evaluation after confirming how a customer employs a machine, and to give an advice about the optimum model depending on the state of use of the machines.

A construction machine comprises a location detector for detecting location information for the construction machine, a determination device for determining whether or not location information is to be transmitted and outputting a transmission signal if it is determined that information is to be transmitted, and a transmitter for transmitting the detected location information to a base station in response to the transmission signal.

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 security system for a construction machine including a construction machine equipped with a body controller for storing a first password, management apparatus arranged in a location apart from the construction machine and a portable communications unit for storing a second password provided communicably with the management apparatus and the body controller. The portable communications unit, receiving the first password from the management apparatus, replaces the second password with the first password. The body controller determines whether the second password output from the portable communications unit coincides with the first password. In case these passwords coincide with each other, an engine drive signal is output. Otherwise the engine is kept inoperable. This prevents possible theft of a construction machine.
