Description

  The present invention displays the gas usage data accumulated in the gas meter as a list of each hour of each day, which is color-coded according to the usage, so that there is a danger of gas leakage for a small gas usage. The present invention relates to a technology capable of promptly determining whether or not the above is true.

  Conventionally, a gas meter has a function of displaying a warning as a gas leak when a small amount of gas continues to flow for several days.If such a small gas leak warning occurs, the gas supply is temporarily stopped. After stopping and performing a leak check and a security check by measuring the pressure drop, the gas supply is started again. However, if the gas is always consumed for business use, the above-mentioned function may operate even if there is no gas leakage. Hearing about is also performed. In addition, after repairing a gas leak, it took 15 to 30 days to determine whether or not the situation had improved, which required a great deal of labor and time.

  The present invention has been made in view of the above circumstances, and provides a gas use status display system capable of promptly detecting danger of gas leakage.

  The gas usage status display system according to claim 1 of the present invention includes a gas meter, a data reading unit, and a data display unit, wherein the gas meter has a data storage unit, and the data storage unit has a gas usage amount. The data is stored, the data reading unit reads the gas usage data, and the data display unit divides the gas usage into each hour of each day and displays the data as a list.

  In the gas usage status display system according to claim 2 of the present invention, in addition to the description of claim 1, the gas usage amount divided at each time each day is color-coded according to the gas usage status. The data is displayed on the data display unit.

  According to the first aspect of the present invention, a gas sales company that performs maintenance of gas supply facilities can know the usage status of each consumer every day and every hour without conducting interviews with gas consumers. Therefore, the danger of gas leakage can be promptly detected.

  In addition, since the data of the daily gas use status accumulated in the gas meter is acquired and can be checked on the spot, it is possible to know whether the present invention improves the situation within a few days after the repair.

According to the second aspect of the present invention, the gas usage amount divided into each hour and each day is color-coded according to the usage status, so that it is easy to visually understand and the gas usage status can be grasped at a glance. As a result, danger of gas leakage can be promptly detected.

It is the schematic which shows the list | wrist of the gas usage amount divided | segmented by each day and each time displayed on the data display part. It is an enlarged view of A of FIG. It is an explanatory view showing the composition of a gas use situation display system. It is a schematic diagram showing a calendar display in a data display part. 6 is a sequence chart illustrating an example of a data acquisition method.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 3, the gas usage status display system of the present invention includes a gas meter 1 having a data storage unit 4 for storing gas usage data 203, and a gas usage data 203 from the data storage unit 4. It comprises a data reading section 10 to be read and a data display section 20 for displaying the read data.

  The gas meter 1 is provided with a data storage unit 4 for storing a total of 720 gas usage data 203 every hour for at least 30 days, and every one hour, the data storage unit 4 stores the gas usage for one hour. The amount is recorded. In addition, the gas meter 1 generally incorporates a reed switch (porcelain detector) 2 as a container reset switch for resetting the remaining amount information of the gas recorded inside the gas meter. In addition, an LED (light emitting unit) 3 is mounted in addition to the liquid crystal panel so that a warning by security information can be recognized even at night.

  In the present embodiment, the smartphone 20 on which a dedicated application is installed is used as the data display unit 20 that transmits the data acquisition request signal 31 to the data reading unit 10 that reads the gas usage data 203. When the application is activated, a GUI is displayed on the screen of the smartphone 20. When the operator selects (tap) the button corresponding to the usage status data for 30 days from the selection buttons displayed corresponding to each data name on the pattern selection screen, the smartphone 20 transmits the data to the data reading device 10. An acquisition request signal 31 is transmitted. The connection interface at this time uses a wired connection such as USB or a wireless connection such as Bluetooth (registered trademark).

The data reading unit 10 receives data by a proximity switch 11 for detecting proximity to the gas meter 1, an electromagnet 12 for outputting a magnetic signal 32 to the reed switch 2 of the gas meter 1, and an optical signal 33 from the LED 3 of the gas meter 1. And a phototransistor (light receiving unit) 13.
In this embodiment, the proximity switch 11 uses a mechanical proximity switch that switches on mechanically and recognizes a distance when the proximity switch 11 is in contact with the gas meter 1. May be used. The proximity switch 11 detects proximity by coming into contact with the gas meter 1, and the data reading unit 10 starts communication with the gas meter 1 in response to the proximity detection.

When the gas meter 1 detects the data selection signal 32 received by the reed switch 2, the data accumulation unit 4 converts the hourly gas usage information for the past 30 days into an optical signal 33 from the LED 3 and outputs it.
When receiving the optical signal 33 from the gas meter 1, the data reading unit 10 generates data 34 to be transmitted, and transfers the data 34 to the smartphone 20 via the interface.

  The data 34 transferred to the smartphone 20 is displayed on the data display unit 20 as a gas usage list 201 for each hour and each day as shown in FIG. In the present embodiment, the smartphone 20 is used as the data display unit. However, another form such as a personal computer or a dedicated terminal device may be used.

The gas usage data 203 for the 30 days is displayed as a grid-like list 201 separated by each hour and day as shown in FIGS. The grid 202 indicates one hour of a certain day, and the grid 202 is filled with a color along the legend 210 corresponding to the amount of gas used in the hour. The gas usage is displayed in L (liter), and is large (for example, 100 L or more) 211, medium (for example, 21 L or more and less than 100 L) 212, small (for example, 2 L or more and less than 21 L) 213, small 213 and less than 213, and unacquired data 215, respectively. In particular, the small 213 is set to a gas usage that exceeds the lower limit flow rate that can be detected by the gas meter and that is lower than the normal usage (such as cooking and bathing) in a general household. However, since there is a danger of gas leakage, the grid 202 is painted in a conspicuous color different from the color indicating the normal usage amount. When gas leakage is suspected, the small particles 213 are continuously detected for a long time, and therefore, as shown in FIGS. 1 and 2, the squares 202 painted with the color are displayed substantially in a line. You. The thresholds of the large 211, the medium 212, and the small 213 can be freely set in the application. In this embodiment, the large section 211 is colored blue, the middle section 212 is colored light blue, and the small section 213 is colored red.
In addition to the above, the day when the small 213 is detected, that is, the day when there is a time zone in which the square 202 is painted in red, is displayed by scrolling the screen of the smartphone 20. Under the date 221, the graphic 222 is drawn in the same color as the color in which the square 202 is painted out, so that the date on which gas leakage is suspected can be easily confirmed.

According to the above configuration, as shown in FIG. 1, when the list 201 in which the gas usage at each hour and each day is color-coded according to the usage is viewed on the data display unit 20, the gas distributor can display the gas usage status of the day. At a glance, it is possible to judge whether the gas has been used continuously for a short period of time, or whether it is a minute flow that is continuous for a long time, such as a gas leak, without conducting interviews with gas consumers. Enables prompt response.
In addition, if a distinctive color, such as the large 211 or the middle 212, that indicates the flow rate of the gas during normal use is used as the color indicating the small gas flow rate such as the small 213, The fact that the flow rate of the natural gas is detected is conspicuous, and the effect of making it easier to visually determine the expected flow rate is expected.

  In addition, since it is possible to grasp the gas usage status for a certain period, it is possible to determine in a few days the effect of the repair, which conventionally required a period of 15 to 30 days in repairing a gas leak, so that the repair work can be performed. The number of days can be reduced.

In this embodiment, the data reading unit for reading data from the gas meter uses a device independent of the data display unit, but a device having both functions may be used.
In the present embodiment, the accumulated gas use status data is every hour for 30 days. However, the accumulated period may be longer or shorter than 30 days, and the time interval is not limited to every hour. It may be finer or coarser.
In addition, the coloration of the squares according to the gas usage status may be, for example, shades of color or hatching, or may be displayed using symbols in addition to the squares.
