Abstract

To provide an information transmitting device for a construction machine such that operation data of the construction machine can be supplied only as much as needed by its user or the like without unnecessary data, the information transmitting device is provided with an information control device 4, a base station 9 arranged at a remote place, a transmission means such as a communication satellite 6, and a selected data outputting means for selecting and predetermined operation data from operation data collected in an operation data collecting unit 4a of the information control device 4 and transmitting them. The information control device includes an operation data collecting unit 4a and a communication control unit 4b which includes transmitting and receiving parts. The selected data outputting means is constructed including an operation data selecting device 9e (external operating device 12) and as units arranged in the information control device 4, an identifier designating unit 4c for designating an identifier TN or the like for the specification of selected operation data, an identifier memory unit 4d, and a transmission data preparing unit 4e for reading operation data, which correspond to an identifier designated by the identifier designating unit 4c, from the operation data collecting unit 4a and preparing the operation data as transmission data.

Claims

1. An information transmitting system for a construction machine, said system comprising an information control device, which includes an operation data collecting unit and a transmission unit for transmitting operation data collected in said operation data collecting unit, and to be mounted on said construction machine, a base station arranged at a place remote from said construction machine for being inputted with said operation data, and a transmission means for transmitting said operation data, which are transmitted from said transmission unit of said information control device, to said base station, characterized in that:

said information transmitting system is provided with a selected data outputting means for selecting predetermined operation data from said operation data, which have been collected in said operation data collecting unit of said information control device, and transmitting said predetermined operation data.

2. An information transmitting system according to claim 1, wherein said selected data outputting means comprises:

an operation data collecting device for outputting a command signal to select said predetermined operation data;

an identifier designating unit arranged in said information control device to designate an identifier for the specification of said operation data selected in response to said command signal outputted from said operation data collecting device; and

a transmission data preparing unit arranged in said information control device to read operation data, which correspond to an identifier designated by said identifier designating unit, from said operation data collecting unit and to prepare said operation data as transmission data.

3. An information transmitting system according to claim 2, wherein said selected data outputting means comprises:

an identifier memory unit arranged in said information control device to store said identifier designated by said identifier designating unit.

4. An information transmitting system according to claim 2 or 3, wherein:

said operation data selecting device is arranged at said base station; and

said information control device to be mounted on said construction machine has a receiving part for receiving a command signal, which is outputted from said operation data collecting device of said base station, via a predetermined transmitting means.

5. An information transmitting system according to claim 2 or 3, wherein said operation data selecting device comprises a portable, external operating device connectable to said information control device to be mounted on said construction machine.

6. An information transmitting system according to any one of claims 1-3, further comprising an operating device to be arranged on a side of a user, said operating device being connectable to said base station via a communication means such that said data transmitted to said base station can be read.
