Problems solved by technology

Therefore, although the improvement of reliability can be realized at the point of determining the use of a gas appliance based on the information sent from a single gas appliance, a flute device that generates a sound corresponding to the flow rate and a loudspeaker and a loudspeaker for collecting the sound are required. Analyzing circuits, there are problems that require extremely complex circuit configurations
[0011] In addition, in recent years, in addition to gas appliances, accidents related to the durability of appliances powered by oil or electricity are on the rise, and while the necessity of periodic inspections is being re-examined, there is still a reality that the following system has not been constructed system of reporting the appropriate inspection time from the point of view of the durability of the appliance

Embodiment approach 1

[0134] figure 1 It is a structural block diagram of the appliance management system in Embodiment 1 of this invention.

[0135] In the home, there are appliances A, B, and C that use the supplied gas as energy, and they are connected to the flow measurement unit composed of an ultrasonic flowmeter 11 and the like connected to the gas supply pipe 20 of the gas supply pipeline. piping connections. Furthermore, the gas flow rate flowing when the gas appliance is used is detected by the ultrasonic flow meter 11 .

[0136] The ultrasonic flowmeter 11 is connected to the path of the gas supply pipe 20, and uses an ultrasonic signal to obtain a transit time difference caused by the gas flow in the gas supply pipe 20 to detect the instantaneous flow rate of the gas. The flow calculation unit 12 performs various calculations related to the flow rate as follows based on the detected instantaneous flow rate: calculates the flow rate value based on the average of the instantaneous flow ...

Embodiment approach 2

[0144] Next, Embodiment 2 of the present invention will be described. Embodiment 2 is characterized by a configuration in which the main components in Embodiment 1 are installed in a gas shutoff device which is a user's house device.

[0145] first, figure 2 It is a figure which shows the appliance management system which mainly consists of the gas appliance in Embodiment 2.

[0146] exist figure 2 Among them, a management center device (monitoring center) 40 that manages the gas supply pipeline including the gas supply pipe 20, and a user house device 10 installed in a gas user's house or the like are configured. The management center device 40 and the user's house device 10 are connected via a communication section (communication unit) 41 such as a public telephone line, a mobile phone line, an optical communication line, a wired or wireless LAN, a wide area wireless or a relay wireless, or other communication interfaces, and can send and receive Various signals or info...

Embodiment approach 3

[0179] Next, for Embodiment 3 of the present invention, use Figure 9 Be explained. The gas appliance management system according to Embodiment 3 includes a management center device 140 for managing gas supply lines including a gas supply pipe 120 and a user house device 110 installed in a gas user's house or the like. The management center device 140 and the user's house device 110 are connected via communication units 141 such as public telephone lines, mobile phone lines, optical communication lines, wired or wireless LAN, wide area wireless or transit wireless, and other communication interfaces, and can send and receive various signals or information . In addition, the user display device 142 for externally checking the user's use status is connected to the communication unit 141 , and various signals and information can be transmitted and received between the management center device 140 and the user display device 142 .

[0180] The user house device 110 is installed ...

Abstract

Provided is an instrument management system, in which information on an accumulated time period or the like is acquired in real time from the kind and installation of a tool used at home, so that the inspection time can be grasped beforehand to prevent the failure of the tool in advance. The instrument management system comprises a tool discrimination unit (13) for discriminating a gas tool to be used, on the basis of an instantaneous flow rate determined by a predetermined processing operation from the measured value of a flow measuring unit (11), an instrument setting unit (43) capable of inputting arbitrarily the tool information of the monitoring object tool, a tool registering unit (14) for registering the monitoring object tool, on the basis of the discrimination result of the tool discrimination unit (13) and the input result of the instrument setting unit (43), a timer unit (16) for accumulating and storing the elapsed time periods separately of the registered tools from the time instants when the monitoring object tool is stored in the tool registering unit (14), a communication unit (41) connected through communication lines with a monitor center (40), for performing communication operations of flow information or tool information, and a control unit (15) for comparing the accumulated time period of the timer unit (16) and a predetermined monitor time period, and for outputting a signal to inform a gas company or a user when the accumulated time period exceeds the monitor time period.

Description

technical field [0001] The present invention relates to an appliance management system and a gas supply system. The appliance management system uses a gas meter installed in a house or the like to measure the flow rate of gas to grasp the usage status of appliances or gas supply lines, monitor the installation status of appliances, and Administer security processing, etc. Background technique [0002] The gas supply system is a system in which gas companies, propane gas operators, etc. charge users gas fees based on the amount of supplied gas used. When using appliances, in order to prevent accidents caused by forgetting to turn off the gas or gas leakage, etc., it is popularized in the center of the gas user's house and other usage places or gas supply pipeline management centers. A system that notifies or cuts off the gas supply pipeline at any time. [0003] At present, maintenance services such as periodic inspections of gas appliances are regularly performed by gas co...
