Abstract

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.

Claims

1. A construction machine management system that receives information transmitted from a construction machine at a receiver provided in a base station, wherein:

the construction machine comprises a location detector that detects location information of the construction machine, a determination device that determines whether the location information is to be transmitted and that outputs a transmission signal if it is determined that the location information is to be transmitted, a fault detector that detects whether there is a fault of the construction machine, and a transmitter that transmits the location information that has been detected to the base station for a notification in response to the transmission signal and that also transmits fault information, in addition to the location information, when the fault has been detected at a time of outputting the transmission signal.

3. A construction machine management system according to claim 1, further comprising:

a base station side transmitter, provided in the base station, that transmits the location information received by the receiver to another organization.

2. A construction machine management system that receives information transmitted from a construction machine at a receiver provided in a base station, wherein:

the construction machine comprises a location detector that detects location information of the construction machine, a storage device that stores the location information detected when an engine of the construction machine is stopped, a determination device that determines whether the location information detected when the engine is started is separated from the location information detected and stored when the engine was stopped by a predefined distance or greater and that outputs a transmission signal when there is the predefined distance or greater, and a transmitter that transmits the location information detected when the engine is started to the base station for a notification in response to the transmission signal.

4. A construction machine management system according to claim 2, further comprising:

a base station side transmitter, provided in the base station, that transmits the location information received by the receiver to another organization.
