Abstract

An information transmitting device to supply operation data of a machine as needed and without unnecessary data. The information transmitting device includes information control device 4, remote base station 9, transmission means, e.g. communication satellite 6, and selected data outputting means for selecting and transmitting predetermined operation data from operation data collected. Information control device includes operation data collecting unit 4a and communication control unit 4b which includes transmitting and receiving parts. Selected data outputting means includes operation data selecting device 9e (external operating device 12) and, in information control device 4: identifier designating unit 4c for designating an identifier for selected operation data, identifier memory unit 4d, and transmission data preparing unit 4e for reading operation data, which correspond to an identifier designated by identifier designating unit 4c, from operation data collecting unit 4a, and preparing operation data for transmission.

Claims

1. An information transmitting system for a construction machine, said system comprising an information control device, which includes an operation data collecting unit for collecting various operation data 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 operation data collecting unit is provided with a memory area for storing operated dates and identifiers for specifying said various operation data, respectively, wherein details of said operation data are stored together with their corresponding identifiers,

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;

said selected data outputting means comprises an operation data collecting device for outputting a command signal to select said predetermined operation data on a basis of a data pattern consisting of plural operation data, an identifier designating unit arranged in said information control device to designate an identifier for the specification of said operation data selected from said data pattern 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; and

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.

2. An information transmitting system according to claim 1, 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.

3. An information transmitting system according to claim 1, 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.

4. An information transmitting system according to claim 1, 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.
