And the installed gas consuming device 5.
[0028]
In a gas consuming area, for example, a general house, gas appliances such as a water heater 11, a gas stove 12, a bath 13, and a stove 14 are installed. For these gas appliances, a gas cylinder 15 to a regulator 16 and a gas stove 14 are provided. Gas is supplied through the supply pipe 17.
[0029]
The gas consuming side device 5 communicates with the gas meter 41 with a built-in microcomputer attached to the gas supply pipe 17, the integrated value counter 42 to which the meter reading result of the gas meter 41 is supplied, and the management device 2. Transmission device 43. Further, the integrated value counter 42 and the gas meter 41 are connected to the in-home display 18 and the gas leak alarm 19.
[0030]
The management device 2 can acquire various gas usage data such as the gas usage amount from the consuming device 4 by remote control.
[0031]
(Integrated value counter)
FIG. 2 is a schematic block diagram showing the internal configuration of the integrated value counter 42 of this example. As shown in the figure, the integrated value counter 42 includes a control unit 110 including a microcomputer, a storage unit 120 storing and holding various data, a display unit 130 including a liquid crystal display, and the like. An operation unit 140 for performing switching and the like, and a communication unit 150 for performing communication between the gas meter 41, the transmission device 43, the gas leak alarm 19, and the like are provided. In addition, it has a usage flow rate integrated value counting unit 160 that calculates an integrated value of the gas usage amount at every certain time (usage flow rate integrated value) at regular time intervals based on the gas meter value supplied from the gas meter 41. .
[0032]
The storage unit 120 stores and holds a control program for realizing the functions described later, stores a gas use determination integrated value storage area 121, a continuous use warning time storage area 122, and stores a continuous non-use time. An area 123, a storage area 124 for gas usage data, a storage area 125 for continuous use time and continuous non-use time data, and a storage area 126 for various warning histories are included.
[0033]
The control unit 110 functions as each unit described below by executing the control program. That is, the usage flow rate integrated value for each predetermined time calculated by the usage status flow integrated value counting unit 160 is compared with a predetermined integrated value for gas use determination, and the gas flow rate in the gas consuming area 4 is determined every predetermined time. It functions as a gas use determination unit 111 that determines whether gas is used or not. The integrated value of the usage flow rate and the determination result of gas use / non-use for each predetermined time are stored and held in the storage area 124 as gas usage status data.
[0034]
Further, the control unit 110 uses the continuous use time calculation unit 112 that calculates the continuous use time for continuously using the gas based on the determination result of the gas use determination unit 111, and uses the gas continuously. It functions as a continuous non-use time calculation unit 113 that calculates a continuous non-use time.
[0035]
Further, a continuous use warning determination for determining whether or not the calculated continuous use time exceeds a predetermined continuous use warning time, and a continuous nonuse warning time for which the calculated continuous nonuse time is predetermined. A non-use warning judgment to determine whether or not gas has been exceeded, and during a predetermined period such as one week, if there is at least one gas non-use, it is determined that there is no gas leakage. In this case, it functions as the determination unit 114 that determines that there is gas leakage.
[0036]
Further, when the determination unit 114 determines that the continuous use warning time has been exceeded, when it is determined that the continuous non-use warning time has been exceeded, and when it is determined that there is a gas leak, Each functions as a warning generation unit 115 that generates a continuous use warning, a continuous nonuse warning, and a gas leak warning.
[0037]
Based on a command issued from the warning generation unit 115, a warning display corresponding to the content of the warning is displayed on the display unit 130. Further, the gas leak alarm 19 can be remotely controlled via the communication unit 150 to generate an alarm.
[0038]
In this example, data relating to the continuous use time and continuous non-use time of gas in the gas consuming area 4 is stored and held in the storage area 125, and the history data of various warning occurrences is stored and held in the warning history storage area 126. You.
[0039]
Here, the integrated value for gas use determination, the continuous use warning time, and the continuous non-use warning time stored and held in the storage unit 120 can be changed via the operation unit 140. Instead, these values may be changed from the management device 2 side via a communication line.
[0040]
FIGS. 3A and 3B are an explanatory diagram showing an operation of determining whether or not gas is used in the gas use determining unit 111, and an explanatory diagram showing an example of utilizing the determination result.
[0041]
The gas usage determining unit 111 integrates, for example, meter reading data supplied every 10 minutes from the gas meter 41 side, and compares the usage status flow integrated value integrated every hour with the integrated value for gas usage determination, for example. Then, it is determined whether or not gas is used.
[0042]
In the gas use determination, for example, when the integrated value for gas use determination is zero, it is determined that the gas is not used if the integrated value of the usage status flow rate is zero, and is used if the integrated value of the usage status is greater than 0. Also, if a gas appliance that constantly burns the ignition is used, the gas use determination value is set to a value corresponding to the amount of gas used by the ignition, and if the integrated value of gas use status <the integrated value for gas use determination, If not used, integrated value ≧ integrated value for gas use determination, it is determined to be used.
[0043]
When the determination is made in this manner, the black square in FIG. 3A indicates the time zone in which the gas is used. In addition, as shown in FIG. 3B, a table of one week can be created so that the time zone in which the gas is used can be clearly understood. For example, by entering "1" for the gas use time zone and "0" for the gas non-use time zone, it is possible to grasp the gas use situation in the gas consuming area 4.
[0044]
In the gas use state data storage area 124, the determination result of the gas use state as shown in FIG. 3A and the gas use state integrated value for each time are stored and held in a form associated with each other.

The determination unit 111 compares the gas usage flow rate integrated value obtained by integrating the meter reading data with the gas usage determination integrated value each time meter reading data is supplied every 10 minutes from the gas meter 41 side. It is determined whether or not gas is continuously used.
[0047]
For example, if the integrated value for gas use determination is zero, the gas use flow rate is not used if the integrated value of gas use flow rate is zero, and if the integrated value of gas use flow rate is greater than 0, the use is determined if the integrated value for gas use determination is zero. Is determined. In addition, when a gas appliance that constantly burns an ignition is used, the integrated value for gas use determination is set to ≠ 0, and if the integrated value of gas use flow rate every 10 minutes <the integrated value for gas use determination, If it is not used, the integrated value of gas use flow rate ≧ the integrated value for gas use determination, it is determined to be used.
[0048]
The continuous use time calculation unit 112 and the continuous non-use time calculation unit 113 calculate the continuous use time and the continuous non-use time based on the determination result. When the calculated continuous use time exceeds the preset continuous use warning time, the determination unit 114 outputs a determination signal to that effect to the warning generation unit 115. The warning generation unit 115 drives the display unit 130 to display a warning as shown in FIG.
[0049]
FIGS. 5A and 5B show a case operation in the case where continuous use is not performed and a warning display example thereof.

Furthermore, it is possible to accurately detect abnormalities in the life of a resident at a single-person home. In addition to this, if a home time zone is obtained based on the gas usage status data and, for example, maintenance of the gas meter is performed in that time zone, it is possible to avoid the harmful effects of being unable to work due to absence.
[0052]
Furthermore, based on the history of warnings of continuous use of gas, non-use of gas, and gas leaks, it is possible to take measures such as strengthening the monitoring of gas consumption areas where warnings are frequently generated. Also increase.
