Publication number: 20230019724Abstract: A gas meter (10) includes a normal measurement mode in which the flow rate is measured in a predetermined sampling period and a detailed measurement mode in which the flow rate is measured in a sampling period shorter than the predetermined sampling period in the normal measurement mode. A center device (40) gives an instruction to the gas meter (10) to measure the flow rate in the detailed measurement mode. The center device (40) further collects flow rate data measured in the detailed measurement mode from the gas meter (10), and generates, based on the collected flow rate data, failure diagnosis information for diagnosing a failure in a gas appliance. With this configuration, the failure part in the gas appliance can be remotely identified, which accelerates the repair work.Type: ApplicationFiled: January 14, 2021Publication date: January 19, 2023Inventors: TADANORI SHIRASAWA, MITSUO YOKOHATA

Patent number: 8442696Abstract: Setting safety function, as appropriate, according to a user environment is enabled, thereby enhancing safety function. According to selection information from a safety function selection unit 120, a function setting unit 116 sets arbitrary function among a plurality of functions as safety function pertaining to usage of a gas. When operating conditions for safety function are fulfilled, a monitoring unit 112 detects malfunction, which would arise during usage of a gas, and outputs a safety signal to a control unit 114 in accordance with the set safety function. In accordance with a safety signal from the monitoring unit 112, the control unit 114 cuts off a gas supply when an event fulfilling operating conditions for the set function has arisen. When an event fulfilling operating conditions for an unset function has arisen, a communication unit 124 reports occurrence of malfunction pertaining to unset function to the monitoring center 200.Type: GrantFiled: February 24, 2009Date of Patent: May 14, 2013Assignee: Panasonic CorporationInventors: Mitsuo Yokohata, Hirozumi Nakamura, Tadanori Shirasawa, Kazuo Kubo, Mitsuo Namba, Hisashi Saito

Publication number: 20110010110Abstract: A challenge to be met by the present invention is to enable appropriate setting of safety function according to a use environment and enhance safety function. An IC card (118) stores data pertaining to the quantity of available gas and at least one safety function program. An IC card reading unit (122) reads information stored in the IC card (118). From the read information, an IC card determination unit (126) determines whether or not the IC card (118) is normal. A safety function detection unit (128) detects a safety function program from the read information and stores the program in a safety function storage unit (130). When the IC card (118) is normal, a function setting unit (116) imparts a safety function program to a monitoring unit (112). A remaining available quantity count unit (124) determines a remaining quantity of available gas from the read quantity of available gas and a flow determined by a flow computing unit (110).Type: ApplicationFiled: February 24, 2009Publication date: January 13, 2011Applicant: Panasonic CorporationInventors: Mitsuo Yokohata, Hirozumi Nakamura, Tadanori Shirasawa, Kazuo Kubo, Mitsuo Namba, Hisashi Saito
