Title:
CONSTRUCTION WORK CONTROLLER
Document Type and Number:
Japanese Patent JP2953137
Kind Code:
B2
Abstract:
PURPOSE: To provide a construction work controller which is superior in portability and easily installed and precludes a malfunction.
CONSTITUTION: The construction work controller is set on a construction machine. A vibration sensor 12 detects the vibration generated by the construction machine and a control part 21 generates vibration data. When the vibration data are varied while crossing a predetermined threshold level, the control part 21 generates operation data including the vibration data and time data. A reader writer 24 writes operation data on a noncontact type IC card 2. The vibration sensor 12 is incorporated in a case 10, so no external noise enters the vibration sensor 12, etc. Further, the construction work controller can easily be set on the construction machine.
