Global monitoring and support management system for construction machinery using satellite communication

Komatsu Ltd. has been providing construction machine to our customer since 90 years ago and our biggest task is to obtain maximum customer satisfactions with our maximum benefit. The customer satisfaction is to keep their machine good condition and the customer can utilize machine whenever they want to utilize it. On the other hands our benefit is not only profit through our sales of machine itself, parts and service but also information from machine related to their performance, durability and utilization data. In order to implement both tasks we have developed several IT systems such as Komtrax (Komatsu Trucking system) for general construction machine and VHMS (Vehicle Health Monitoring system) for mining equipment through satellite communication or mobile network. We can obtain several data, for example, machine position, operating hours, error codes, fuel consumption and trend health data of each component. We can access the machinery positively without customer call and offer several services to keep machine good condition. In this paper I would like to mention more details about Komtrax and VHMS including the outline of our service operation.
