Patent number: 9334820Abstract: A component monitoring system monitors whether a component fitted to a working machine is a genuine component, and prevents the use of a counterfeit product or the like. A working machine is provided with a plurality of exchangeable components, and each component is provided with a wireless tag. A component ID is stored in advance in the wireless tag. When, on the side of the working machine, a component exchange timing or an engine starting timing is detected, the component ID stored in the wireless tag is acquired, and is transmitted to a working machine management device. The working machine management device checks the component ID which has been received from the working machine and a component ID which is stored in a component ID storage means against one another. And, if these two component IDs do not match one another, an abnormal state detection means outputs a warning signal.Type: GrantFiled: June 10, 2013Date of Patent: May 10, 2016Assignee: Komatsu Ltd.Inventors: Atsutomo Komine, Yukihiro Tsuda, Hidenori Koizumi

Patent number: 8072604Abstract: An apparatus for detecting a property of fuel detects the property of fuel at the time of fuel supply. A measuring chamber member is provided to a fuel tank. The greater portion of fuel supplied from a fuel supply nozzle falls down from a fuel supply aperture via a flow outlet into the fuel tank. However, a part of the fuel remains in a measuring space defined between a portion below the flow outlet and a bottom portion. A fuel property detection sensor is fitted to a main body so as to oppose the measuring space. When application of a cap to the fuel supply aperture has been detected by a fuel supply cap sensor, if increase of the remaining fuel amount has been detected by a remaining fuel amount sensor, or if the engine is started, a controller measures the property of the fuel with the fuel property detection sensor.Type: GrantFiled: May 30, 2007Date of Patent: December 6, 2011Assignee: Komatsu Ltd.Inventors: Shuji Arakawa, Hidenori Koizumi

Publication number: 20100231371Abstract: The fuel nature discriminating system of the present invention discriminates whether or not a fuel fed to a working machine is the normal one, and performs appropriate control operation by analyzing the result of discrimination. The fuel fed from a fuel supply nozzle flows into a fuel tank through a fuel catching portion. Fuel nature detecting means measures the nature of the fed fuel at a predetermined timing (or at the time of refueling). Measured data generating means generates measured data on the basis of the measurement result and also the remaining amount of fuel and the environmental temperature. And, in accordance with the result of analysis of the measured data, a measured data analyzing means executes restriction of the engine output, issues a warning to the user, and alteration of an evaluation of the user.Type: ApplicationFiled: May 30, 2007Publication date: September 16, 2010Applicant: Komatsu Ltd.Inventors: Shuji Arakawa, Hidenori Koizumi

Patent number: 7756736Abstract: A server (10) enables users (A-B) sharing the same working machine (1) to mutually monitor a usage state by each user. The server (10) receives a user ID, the working time, the engine cooling water temperature, and the current position that are detected in the working machine (1) through a satellite communication network, and calculates the usage time, the usage location, the load amount, and a usage proportion for each user. The server (10) sends a warning to the user terminals 20 when the usage time or location is not as planned, or the load amount is excessive. The server (10) periodically reports the usage times and locations, the load amounts, and the usage proportions for the users (A-B) to the user terminals (20). The server (10) allocates maintenance costs of the working machine (1) automatically between the users (A-B) according to the usage proportions of the users (A-B).Type: GrantFiled: October 26, 2004Date of Patent: July 13, 2010Assignee: Komatsu LtdInventors: Tetsuya Nakayama, Shuji Arakawa, Yukie Nishikawa, Hidenori Koizumi
