現在の合計流量が越えた場合、遮断手段を作動させる。Here, the appropriate usage conditions include items such as the total flow rate, individual maximum flow rate, and safe continuous usage time set according to the capacity of each gas meter. The total flow rate is the total flow rate of gas that passes through the gas meter within a predetermined measurement period.If the current total flow rate exceeds the initially set predetermined value, such as when a gas hose is disconnected or the combustion of a gas appliance goes out, the shutoff means is activated. let

。The individual maximum flow rate is calculated by detecting changes in the gas flow rate at each predetermined measurement period, identifying how many types of gas appliances are currently in use and how much gas each one consumes, and calculating the maximum gas consumption among them. When the amount exceeds a set value, a closing signal is output to the shut-off means to prevent gas leaks such as cracks in the gas hose or combustion going out when the gas valve is half-open. In addition, the safe continuous use time is the continuous use time set for each range based on the statistical data of the time when a gas appliance in a certain combustion range is continuously used. When the time limit is exceeded, an activation signal is sent to the shutoff means to ensure safety even when the user forgets to turn off gas appliances.

になる。If the first temperature determination signal after installing the gas cutoff device is output during the transition from winter to summer, the outside temperature has become the summer temperature TH, and the appropriate gas usage condition setting section 17 has set the appropriate gas usage conditions. The appropriate gas usage conditions at the summer temperature in the storage storage section 16 are compared with the initial conditions in the initial condition setting section 7, and the smaller one is set in the gas appropriate usage condition setting section 17 as the appropriate gas usage conditions. In the first year, the maximum value is stored in the gas appropriate usage condition storage unit 16, so the initial conditions are set in the gas appropriate usage condition setting unit 17, and the usage status storage unit 14 stores the initial conditions while the timer unit 13 is operating. After the timer count ends, the proper gas usage conditions based on the actually measured gas usage pattern during the summer period are stored in the storage unit 16 for proper gas usage conditions.
Stored in storage during summer temperatures. Next, if the second temperature determination signal is output at the time when summer changes to winter, the outside temperature has become the winter temperature TL, and the gas appropriate usage condition setting unit 17 has the gas appropriate usage condition storage unit 16.
The gas appropriate usage conditions at the winter temperature are compared with the initial conditions in the initial condition setting section 7, and the smaller one is set as the gas appropriate usage conditions in the gas appropriate usage condition setting section. In this case, the initial conditions are set in the same way as the first time. Further, the timer section 13 and the usage state storage section 14 store the actual gas usage pattern during the winter period, and the appropriate gas usage conditions are stored in the storage section for the winter temperature in the gas appropriate usage conditions storage section 16 after the timer count ends. It will be stored. The summer and winter gas usage patterns are now stored in their respective memory storage units.
During the transition from winter to summer in the second year, the summer usage conditions of the previous year stored in the gas proper usage condition storage unit 16 and the initial condition setting unit 7 are updated based on the temperature determination signal based on the summer temperature from the temperature condition determination unit. The initial conditions are compared and the smaller value is set in the gas appropriate usage condition setting section 17. At the same time, the gas pattern for the summer period of the second year is actually measured by the operation of the timer section 13 and the usage state storage section 14, and when the timer count ends, the proper gas usage conditions for the summer of that year are stored in the gas proper usage conditions storage section 16. It is stored in the storage section during summer temperatures. Thereafter, in the same way, each time the temperature determination signal from the temperature condition determination section 12 is output, the setting contents of the gas appropriate usage condition setting section 17 are changed.
It compares the initial conditions in the gas proper usage condition initial condition setting section that were actually measured and stored at the same time last year, and the proper gas usage conditions to be used are reset, and at the same time the actual measurement of the gas usage status for that year starts. . In other words, by detecting the temperature of the outside air, determining whether the detected temperature satisfies a predetermined temperature condition, and if it does, issuing a temperature judgment signal, the temperature is automatically set at each home at that time. The most suitable gas usage conditions will be set and the gas usage status will be monitored.

ができる。In addition, in the example, the temperature was divided into two, summer temperature and winter temperature (temperature was set in two patterns). By increasing the number of storage sections corresponding to the number of set temperatures, gas usage conditions can be reset to be more suitable for each season, and a more appropriate and safe gas cutoff device can be achieved.

る安全性を一段と増すことができる。Effects of the Invention As described above, the gas cutoff device of the present invention includes a flow rate measuring means that emits a signal according to the amount of gas passing through the gas passage, and detects the usage state of the gas based on the flow rate signal sent from the flow rate measuring means. A usage state detection unit, a temperature detection means for detecting the outside air temperature, and a temperature detection means for determining whether or not the temperature obtained by the temperature detection means satisfies a predetermined condition, and if it satisfies a predetermined condition, making a temperature determination according to the detected temperature. a temperature condition determination unit that outputs a signal; a timer unit that counts a predetermined time based on the temperature determination signal; a usage status storage unit that stores the gas usage status based on the signal from the usage status detection unit while the timer unit is operating; a gas appropriate usage condition change storage unit that changes and stores gas appropriate usage conditions according to the contents of the usage status storage unit;
a gas appropriate usage condition storage unit that stores the stored contents of the gas appropriate usage condition change storage unit in a predetermined storage unit according to the temperature determination signal; and an initial condition setting that sets the gas appropriate usage conditions as an initial value in advance. The temperature judgment signal is used to compare the initial conditions of the initial condition setting section with the appropriate gas use conditions stored in the gas appropriate use condition storage section according to the previous temperature judgment signal, and the gas to be used is determined. Since it is equipped with a gas proper usage condition setting section that sets proper gas usage conditions, it is easier to set conditions than simply setting conditions based on the capacity (number) of the gas meter.
The actual gas usage pattern of each household in each season is actually measured, and the appropriate gas usage conditions for that year's season are reset every year based on the gas usage pattern at the same time in the morning. It is possible to monitor the gas usage status under suitable gas usage conditions and judge whether there is an abnormality, and if an abnormality occurs, the gas supply is stopped by operating the shutoff means, thereby preventing dangerous gas accidents such as gas explosions and gas poisoning. It is possible to further increase safety in terms of prevention.
