Publication number: 20220021954Abstract: Proposed is an information collection system and method capable of reliably collecting information even from sensors installed at locations where a vehicle cannot pass through, and also promptly collecting information of urgent nature. Each sensor not positioned on a route travelled by a travel vehicle transmits, to sensors of a subsequent stage in multihop wireless communication preset so that information is aggregated in a predetermined sensor positioned on the route travelled by the travel vehicle, information transmitted from sensors of a preceding stage in the multihop wireless communication, as well as its own information, and the sensor positioned on the route travelled by the travel vehicle transmits the aggregated information to a receiver.Type: ApplicationFiled: March 19, 2021Publication date: January 20, 2022Inventors: Keisuke UCHIGATA, Kousuke SHIBATA, Shotaro TANAKA, Takashi TAKAGI

Patent number: 10769767Abstract: A monitoring system monitors a monitoring object apparatus sufficiently for practical use while suppressing battery power consumption. The monitoring system is provided a sensor terminal that is driven by a battery and acquires a measured value(s) of a measuring apparatus mounted in the monitoring object apparatus by executing image analysis processing on a captured image(s) obtained by photographing the measuring apparatus. A manager terminal monitors the measured value(s) of the measuring apparatus which is reported from the sensor terminal. When the measured value is out of a normal range, the manager terminal requests transmission of image data of an image area, which is necessary to check whether the measured value of the measuring apparatus is actually out of the normal range or not. The sensor terminal transmits the requested image data with the requested resolution to the manger terminal in response to the request from the manager terminal.Type: GrantFiled: February 21, 2019Date of Patent: September 8, 2020Assignee: HITACHI, LTD.Inventors: Kazuki Yasukawa, Nobuyuki Shimizu, Kousuke Shibata
