Abstract

To enable positive management of construction machines in a management center. There comprises an construction machine 1, and a management apparatus 20 for carrying out the transmission and reception of information with the construction machine 1 through a communication satellite 30 and a base station 32. The construction machine 1 comprises a memory 124 for storing operating information, information amount discrimination means 127 to discriminate if the operating information stored in the memory 124 reaches a fixed amount, information readout means 128 for reading out the operating information when the operating information stored in the memory 12 reaches the fixed amount, and a transmission section 184 for transmitting the operating information read out. The management apparatus 20 comprises a reception section 214 for receiving the operating information transmitted from the construction machine 1, a memory 208 for storing the operating information received, and data processing means 211 for carrying out data processing relative to the operating information.

Claims

1. A management system for a construction machine, comprising:

a memory means for storing a management information of the construction machine, said management information being operating information relating to time of operation of the construction machine;

a communication means for carrying out transmission and reception of said management information of the construction machine with management center for managing said construction machine using said management information;

a read-out means for reading out said operating information stored in the memory means for the purpose of transmitting said operating information to the management center;

a discrimination means for discriminating if said read-out means fulfills predetermined readable conditions of the operating information stored in the memory means; and

an anti-theft device adapted to cause the construction machine to stop operation in case of receipt by the anti-theft device of a control information relating to an operation stop signal transmitted from the management center.

2. The management system for a construction machine according to claim 1, wherein

in a work area of the construction machine is set in advance, position of the construction machine is measured using a GPS, and when the position measured of the construction machine is outside the work area, the operation stop signal is transmitted to the construction machine.

3. The management system for a construction machine according to claim 1, wherein

said anti-theft device cuts off a power circuit to a starter motor of the construction machine.

4. The management system or a construction machine according to claim 3, wherein

said anti-theft device further cuts off a circuit for supply of pressure oil to each of hydraulic actuators of the construction machine.

5. The management system for a construction machine according to claim 3, wherein

said anti-theft device cuts off a circuit for supply of fuel to an engine of the construction machine.

6. The management system for a construction machine according to claim 1, wherein

said anti-theft device cuts off all of a power circuit to a starter motor, a circuit for supply of pressure oil to each of hydraulic actuators, and a circuit for supply of fuel to an engine of the construction machine.
