Patent number: 8924050Abstract: In a railway signalling system which transmits a control order to an on-board signalling system by a trackside signalling system, the on-board signalling system being mounted on a train running on a line and the control order being compliant with a signalling system of the line, the present invention allows the train to run through into lines with different signalling systems using a single on-board signalling system. When the train enters a line with a different signalling system from a current line, the on-board signalling system installs a train control application program compliant with the signalling system of the entering line. Then, the on-board signalling system executes the train control application program, allowing the train to be controlled on the entering line according to a control order created by the trackside signalling system of the entering line.Type: GrantFiled: July 17, 2012Date of Patent: December 30, 2014Assignee: Hitachi, Ltd.Inventors: Keiichi Katsuta, Yoichi Sugita, Keiji Maekawa, Naoki Shibata, Kenji Imamoto, Motonari Suzuki

Patent number: 7954334Abstract: An inverter system having a semiconductor device, and a railway vehicle using this inverter, provide a more accurate determination of whether an abnormal heat generation from the inverter is associated with an error of the inverter system or is due to other causes, by use of a plurality of temperature detecting elements at a plurality of sites associated with the semiconductor device. An error detection section applies inputs from the temperature detecting elements, captures a trend of the differential value based on the plurality of temperature inputs using period sampling wherein an error associated with the semiconductor device, and not from some other condition such as outside environment temperature, is determined based on differences from, or a change in, the initial trend.Type: GrantFiled: August 18, 2004Date of Patent: June 7, 2011Assignee: Hitachi, Ltd.Inventors: Masataka Sasaki, Hideki Miyazaki, Katsumi Ishikawa, Keiji Maekawa

Publication number: 20050132726Abstract: The object of the invention is to provide an inverter system and vehicles using this inverter wherein accurate detection of the abnormal heat generation from the inverter is ensured, despite a large amount of noise signals, a substantial fluctuation in environmental temperature, or a change of cooling performances resulting from the environmental conditions. Based on the output value of an outside air temperature detecting means 150 and temperature calculation parameters inputted from outside the inverter system, the temperature calculation circuit 144B of an error detecting section 144 calculates the temperature Tcal where a temperature detecting means below semiconductor device 152 is installed.Type: ApplicationFiled: August 18, 2004Publication date: June 23, 2005Applicant: HITACHI, LTD.Inventors: Masataka Sasaki, Hideki Miyazaki, Katsumi Ishikawa, Keiji Maekawa
