Management system for construction machines

The invention relates to a management system for construction machines. The system comprises a construction machine and a management center allowing transmission and reception of control information between these components. The management system includes an anti-theft device which is adapted to cause the construction machine to stop operation in case of receiving a control information relating to an operation stop signal transmitted from the management center. A work area of the construction machine may be set in advance and the actual position of the construction machine can be measured using a GPS. When the position of the construction machine is outside the work area, the operation stop signal is preferably transmitted to the construction machine.
