Abstract

An object of the present invention is to ensure that the amount of time a construction machine has been operated by each operator can be managed. A further object is to ensure that an administrator can learn without delay, in real time, and accurately that a service person has performed services on a construction machine, and to ensure that work instructions are imparted to a service person, and service person performance management and labor management are performed easily and accurately. Another object is to ensure that the attachment situation of a construction machine can be learned accurately and in real time such that customer requests can be dealt with promptly. Another object is to ensure that communication messages can be displayed on the limited space of a monitoring panel display screen together with information which is necessary for driving. When driver identification data (operator ID “010A”) for identifying a driver A is inputted at the operating start time of a work machine 31 (vehicle ID “CAR001”), the inputted driver identification data (operator ID “010A”), the operating time of the construction machine 31 (“2 hours and 15 minutes”), and the time and date (“6:00, May 21”) at which the driver identification data (operator ID “010A”) was inputted are transmitted from the work machine 31 to a terminal device 11. As a result, the amount of time the construction machine 31 was operated by the driver A is displayed on the terminal 11, and the work machine 31 can be managed on the basis of this display content.
