System for controlling operating information of construction machine and construction machine therefor
First Claim
1. A system for controlling operating information of a construction machine comprising:
- operating information collection means at said construction machine for collecting operating information regarding operation of the construction machine;
a first receiving device provided in a base station for said construction machine;
storage means at said construction machine for storing the operating information;
detector means for detecting that the construction machine has left the base station and for detecting that the construction machine has returned to the base station; and
a transmission controller for transmitting the operating information read from the storage means to the first receiving device through a wireless radio having a limited range, including means responsive to a signal from the detector means that the construction machine has returned to the base station for transmitting the operating information read from the storage means to the first receiving device through the wireless radio.

Abstract
The present invention provides an operating information control system of a construction machine comprising: operating information collection device for collecting operating information regarding operation of a construction machine; storage device for storing the operating information; and transmission controller for transmitting the operating information read from the storage device to a first receiving device provided except the construction machine through a wireless radio, the transmission controller capable of transmitting the operating information to the first receiving device when receiving a transmission request from outside of the construction machine, or continuously for a predetermined period. Thereby, since the operating information of the construction machine is transmitted making use of a low power wireless radio without using a communication satellite or a public circuit network, lots of communication cost can be reduced.
