Patent number: 7171188Abstract: Provided is a communication system for working machines, which makes it possible to transmit desired messages from sites, where the working machines are arranged, to their corresponding work administration centers at timings as needed. When a mail switch 10 arranged on a working machine 7 is operated to send information to a server 1, a terminal user-company identification unit 14 identifies, on the basis of a terminal information database 18, a user to which the information so received is to be sent. A user-company-dependent mail selection unit 15 selects customer information 19a on the user from a customer database 19. At a transmission mail creation unit 16, a corresponding new message 16a is created. The mail is then transmitted from a mail output unit 17. In this manner, a desired message can be sent from each working machine 7 at a remote location to the corresponding user at a timing as needed.Type: GrantFiled: May 22, 2000Date of Patent: January 30, 2007Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Hiroshi Watanabe, Koichi Shibata, Genroku Sugiyama, Toichi Hirata, Hiroyuki Adachi, Hideki Komatsu, Yasushi Ochiai
