When the confirmation switch 23a is pressed, the screen is switched to a screen for selecting the use form in S12, and the selection is made based on the appliance information requested by the user through the operation of the operation unit 23. For example, when gas appliances are used for all purposes of hot water supply, bath, floor heating, cooking, and hot air heating, all are selected. When the above setting is completed, the screen is switched to the completion screen in S13 and the initial setting operation is completed. Note that the contents, display method, and confirmation method of the initial setting navigation are not limited to the present embodiment.

And the registration memory | storage means 16 which inputs and memorize | stores the flow rate pattern corresponding to the appliance information input via the information input means 32 according to "initial setting navigation" is provided. In addition, a storage means 31 is provided which stores a characteristic flow rate pattern of gas flow corresponding to the assumed type or usage pattern of the gas appliance in association with the code number, and the code number is input from the information input means 32 by the above setting operation. By inputting the converted signal, the flow rate pattern stored in the storage unit 31 is taken out in the registration storage unit 16 and stored as registration data.

  Then, when instrument information is input from the information input means 32, an instrument signal registration means for setting and registering an instrument signal specifying the type of gas instrument to be used based on the instrument information stored in the registration storage means 16. 17 and a registration signal of application-specific signal registration means 18 for specifying a usage form according to the use of the gas appliance to be used, and the registration information of the appliance signal registration means 17 and the application-specific signal registration means 18, a gas company or the like can specify a specific service, etc. There is provided an appliance specifying means 20 having appliance classification means 19 for classifying the gas appliances used in the home for each item previously classified for.

  Then, the monitoring item classified according to the service provided by the gas company is selected by the classification item selection means 33, and the monitoring item corresponding to the provided service is set in the appliance classification means 19. This selection instruction to the classification item selection means 33 can be made via the information input means 32 in accordance with “initial setting navigation”.

  Here, the appliance signal registration means 17 sets and registers a signal according to the type of appliance, for example, as shown in the following table (Table 1).

  Further, the application-specific signal registration means 18 sets and registers a signal for specifying a use form for each use of the appliance, for example, as shown in the following table (Table 2).

  In addition, the appliance classification means 19 is a service provided by the gas company, in which the fields subject to gas gas discounts are preset and classified based on the type and usage of the gas appliance, and the above (Table 1) and (Table 2). By applying the gas appliances used in the home based on the information obtained in the above, for example, as shown in the following table (Table 3), if floor heating is performed using a water heater, the discount is A, and the gas fan heater If hot air heating is performed, etc., it is set as discount B, otherwise it is classified as standard, and gas appliances used at home are set and registered.

  An appliance determination unit 24 for determining an appliance in use by comparing the flow rate value obtained by the signal processing unit 14 with the registration data (flow rate pattern) of the registration storage unit 16 is provided. The device-specific monitoring means 21 for monitoring the amount of gas used according to the usage status of the gas appliance determined in (1). This appliance-specific monitoring means 21 inputs the gas flow rate value obtained by the signal processing means 14 of the flow rate measuring unit 12, is managed together with the registration information of the gas appliance determined by the appliance determination means 24, and is requested by the gas company. Based on the above, information such as a cumulative flow rate value for each predetermined period is output.

  Here, the outline of the instrument discrimination performed by the instrument determination unit 24 will be described. As the registration data stored in the registration storage unit 16, for example, a flow rate pattern as shown in FIG. As actual registration data, for example, data of a flow rate value every 0.2 seconds from the start of the instrument is stored for a predetermined time. Note that the data time interval does not need to be limited to 0.2 seconds, and can be arbitrarily set depending on the required appliance discrimination capability.

  The flow rate measuring unit 12 measures the gas flow rate at regular intervals, and when the newly measured gas flow rate value increases by more than a predetermined value from the previous value, it is determined that a new instrument has been used, and the flow rate change and registration memory The flow rate pattern corresponding to the instrument code registered in the means 16 is compared to determine the instrument being used.

  In addition, when a signal such as an abnormal flow rate is input from the flow rate measuring unit 12, safety is ensured by blocking the flow path 11 via the cutoff valve 15.

  In the present embodiment, the discount item service is targeted as a classification item of the appliance identifying means 20, but the service is not limited to this, and services that are considered necessary by gas companies, such as security services, are targeted. A monitoring method for each device can be adopted.

  Next, the case where the old gas meter used until now is replaced with a new gas meter by periodic replacement or the like will be described.

  When replacing with a new gas meter, it is not necessary to start from the initial setting newly, and measurement is performed according to the equipment information used so far, the information classified according to the service provided by the gas company, and the classified information. Since the old gas meter stores data that stores the flow rate values that have been stored, the various types of information stored in the old gas meter can be transferred to the new gas meter. The situation can be monitored.

  Therefore, after the replacement work for the new gas meter is completed, a navigation screen for guiding the replacement work is displayed on the display means 22, and the operator operates the operation unit 23 according to the “data transplantation navigation” guided by the display means 22. Port and register.

An example of the “data transplantation navigation” is shown in FIG. 6. First, a guidance as shown in S 21 is displayed as the start screen, and when the confirmation switch 23 a of the operation unit 23 is pressed, S 22 is displayed as the next screen, and the old gas meter Data transmission / reception is started with At this time, if there is a function to send and receive data via wireless communication means, it is necessary to install the old gas meter within the communicable range, and the function to send and receive data via wired communication means It is necessary to connect a communication line between the new gas meter and the old gas meter in advance.

  When the communication with the old gas meter is completed, the screen switches to a screen for guiding the currently registered contract gas company in S23, the contract gas company registered in S24 is displayed, and if there is no change in this registered content, it is confirmed. When the switch 23a is pressed, the screen switches to a screen for guiding the currently registered discount plan in S25, and the discount plan registered in S26 is displayed. If there is no change in the registered content, pressing the confirmation switch 23a switches to a screen for guiding the currently used appliance in S27, and the gas appliance currently registered is displayed in S28. If the confirmation switch 23a is not pressed, the screen switches to a screen for guiding the currently registered usage mode in S29, and the currently registered usage mode is displayed in S30. Then, when the data transplantation of the instrument information is completed, the gas usage data classified and managed are transplanted.

  When there is a change in the device information transplantation process, the change registration can be performed after the change process is performed by operating the switch of the operation unit 23.

  When the above confirmation and change processing is completed, the screen is switched to the completion screen of S32-the porting operation is terminated. Note that the contents, procedure, display method, or confirmation method of data transplantation are not limited to the present embodiment.

  Further, when working in accordance with “initial setting navigation” or “data transplantation navigation”, there is a risk of being operated by a person other than the gas operator. In order to prevent such an action, in the present invention, the front side of the gas meter 2 is used. An opening / closing detection means 29 for detecting that the lid 28 provided on the gas sensor 2 has been removed is provided, and a meter-side wireless communication means 25 capable of transmission / reception is provided in the gas meter 2, and an authentication comprising a wireless key 10 carried by a gas company. When a preset authentication code is transmitted from the code transmitting means, the meter-side wireless communication means 25 receives this authentication code, and when the authentication code confirmation means 26 determines that the received authentication code is normal, the open / close detection means 29 The data transfer by setting processing by the information input means 32 or the specific operation of the switch of the operation unit 23 by invalidating the detection signal of When the cover 28 is removed in a state where the authentication code is abnormal or no authentication code is received, the setting process by the information input unit 32 or the switch of the operation unit 23 via the alarm unit 27 is performed. A warning is given that data cannot be transplanted by a specific operation or the like, or the shutoff valve 15 is activated to shut off the flow path 11 and prohibit the use of the gas meter 2.

  By the above authentication flow, only the gas company or the authorized contractor can perform the data transplantation work by the setting process by the information input unit 32 of the registration storage unit 16 or the specific operation of the switch of the operation unit 23, and the like. This prevents settings that are contrary to or mischievous.

  Moreover, as a structure of the operation part 23, you may provide in the wireless key 10 besides providing in the gas meter 2. FIG.

  In the gas appliance monitoring apparatus configured as described above, the data porting work performed after the completion of the periodic replacement work of the gas meter can be easily performed by the data porting navigation guided by the display means 22, and the work experience is inferior. Even workers can definitely do it.

Further, by storing in the registration storage unit 16 a flow rate pattern for appliance discrimination corresponding to appliance information such as the type or usage pattern of the gas appliance input via the information input unit 32, it becomes possible to make appliance discrimination with high accuracy. In addition, since the appliance registration means 16 can be changed according to the usage status of gas appliances in the home, it can be easily changed when appliances are added, use is stopped, or usage is changed. Can do. Furthermore, the flow measurement data is managed for each monitoring item classified according to the service provided by the gas company, and the monitoring item can be selected according to the provided service. A high value-added gas supply business can be realized. In addition, when changing the appliance registration means and changing the monitoring item, it is not possible to perform a predetermined authentication process, so that it is possible to prevent exchanges that are against the will of the gas company or exchanges due to mischief.

  In addition, after the replacement work of the new gas meter is completed, the stored data of the old gas meter is transferred to the new gas meter according to the guidance of the data transfer navigation. In addition, there is no need to change the billing work for the gas consumption or the service provided by the gas company, and the convenience can be improved.

  Further, since the data porting work at the time of meter replacement is directly performed via the wireless communication unit or the wired communication unit incorporated therein, it is not necessary to prepare a separate porting device, and the configuration can be simplified.

  In addition, when initial setting work or data porting work is performed without performing the predetermined authentication process, it is determined that the replacement is against the gas company's will or mischief, and a warning is issued or the gas flow path is shut off. However, by stopping the use of gas, it is possible to ensure reliability and safety.

  And by using an ultrasonic wave, it is possible to measure an instantaneous flow rate, and to perform instrument discrimination with higher accuracy.

  The present invention is not limited to a monitoring device that specifies the type of gas appliance used in the home and the usage pattern and manages it together with the flow rate data, but also identifies the type and usage pattern for a plurality of appliances used in the office or store, It can also be applied to devices that manage power consumption and water usage.
