Abstract

A data recording unit 60 for managing operating situations of a hydraulic excavator 1 comprises a RAM 67 for taking in and storing plural kinds of operational information regarding the hydraulic excavator 1 as operational data, and a CPU 65 for extracting top priority operational data from among the plural kinds of operational data stored in the RAM 67, and transmitting the extracted data to the supervising side via satellite communication. Top priority data among the plural kinds of operational data of the hydraulic excavator, which may bring the hydraulic excavator into rest, can be presented to a supervisor of the hydraulic excavator, etc.

Claims

1. An operational information managing apparatus for use in a construction machine to manage operating situations of said construction machine, wherein said apparatus comprises:

a first storage unit for storing operational data regarding said construction machine;

a second storage unit for storing a first program for extracting a cumulative run time of an engine from among said operational data stored in said first storage unit, a second program for extracting a per-part operating time per unit time from among said operational data stored in said first storage unit, and a third program for extracting alarm data and snapshot data regarding a relevant alarm from among said operational data stored in said first storage unit; and

a control unit for reading a data extracting program from among said programs stored in said second storage unit corresponding to a remote operation made from a supervising side via information communication, extracting top priority operational data from among said operational data stored in said first storage unit in accordance with said data extracting program, and transmitting said top priority operational data to said supervising side via information communication.

2. The operational information managing apparatus for the construction machine according to claim 1, wherein said second storage unit stores a fourth program for computing a daily data from among said operational data stored in said first storage unit, and a fifth program for computing a life data and a daily data from among said operational data stored in said first storage unit.

3. The operational information managing apparatus for the construction machine according to claim 1, wherein said data extraction program read by said control unit can be changed with an input applied by an operator of said constriction machine from a keypad, or an input applied from a portable terminal connected to said operational information managing apparatus, or said remote operation made from said supervising side via information communication.

4. The operational information managing apparatus for the construction machine according to claim 1, wherein a transmission cycle of said top priority operational data can be changed.

5. The operational information managing apparatus for the construction machine according to claim 1, wherein said control unit sends a snapshot start signal to a display control unit for executing control related to display made on a display means on an occurrence of said alarm is detected.

6. The operational information managing apparatus for the construction machine according to claim 1, wherein said first storage unit takes in and stores, as the operational data of said construction machine, a first kind of operational data regarding the operating status of an engine and a second kind of operational data regarding a body of said construction machine and the operating status of an electric lever thereof.

7. An operational information managing system for a construction machine, said system comprising:

an operational information managing apparatus for use in said construction machine to manage operating situations of said construction machine; and

a remote terminal apparatus connected to said operational information managing apparatus via information communication;

wherein said operational information managing apparatus comprises;

a first storage unit for storing operational data regarding said construction machine;

a second storage unit for storing a first program for extracting a cumulative run time of an engine from among said operational data stored in said first storage unit, a second program for extracting a per-part operating time per unit time from among said operational data stored in said first storage unit, and a third program for extracting alarm data and snapshot data regarding a relevant alarm from among said operational data stored in said first storage unit; and

a control unit for reading a data extracting program from among said programs stored in said second storage unit corresponding to a remote operation made from said remote terminal apparatus, extracting top priority operational data from among said operational data stored in said first storage unit in accordance with said data extracting program, and transmitting said top priority operational data to said remote terminal apparatus via information communication.
