Disclosure of Invention
Problems to be solved by the invention
However, the following problems exist in the above prior art: the possibility of gas exhaustion is high when sudden gas exhaustion occurs.
Accordingly, an object of the present invention is to provide a gas balance management system that is less likely to cause gas exhaustion when sudden gas consumption occurs in a demand house.
Solution for solving the problem
The gas balance management system of the present invention comprises: a flow rate measurement unit that measures gas flowing from a gas container provided for one or more demand houses to a gas facility; a remaining amount calculation unit that calculates a remaining amount of the gas in the gas container based on a measurement result of the flow rate measurement unit; a replacement time estimation unit that estimates a replacement time of the gas container for each of the demand houses based on a calculation result of the margin calculation unit; and a notification unit configured to notify the demand house when the flow rate measurement unit measures the amount of fuel gas that exceeds a fuel gas usage assumption condition.
According to the present invention, the replacement time estimating unit estimates the replacement time of the gas container for each of the demand houses. When the amount of fuel gas exceeding the fuel gas use assumption condition is measured in the demand house, that is, when sudden fuel gas consumption occurs in the demand house, the notification unit notifies the sudden fuel gas consumption. This allows the service provider to take care of, for example, replacement of the gas container in advance. Thus, when sudden gas consumption occurs in the demand house, gas consumption is less likely to occur.
In the above invention, the remaining amount calculating unit may calculate the remaining amount of the fuel gas based on measurement results obtained from one of the flow rate measuring units or based on a sum of measurement results obtained from a plurality of the flow rate measuring units, based on fuel gas container setting information given to each of the demand houses corresponding to the flow rate measuring units.
According to the above configuration, the remaining amount of the fuel gas can be calculated not only when one fuel gas container is provided corresponding to one demand house, but also when one fuel gas container is provided corresponding to a plurality of demand houses.
In the above invention, the gas remaining amount management system may further include a storage unit that stores a gas production rate of the gas in association with a date, and the remaining amount calculation unit may calculate the remaining amount of the gas using the gas production rate in association with the date on which the measurement result of the flow rate measurement unit was obtained.
According to the above configuration, the gas production rate which may vary depending on the date based on the season is used, so that the reliability of the obtained remaining amount information of the gas can be improved.
In the above invention, the storage unit may store the gas production rate in association with a region, and the surplus calculation unit may calculate the surplus of the fuel gas using the gas production rate in association with the region of the desired house.
According to the above configuration, the gas production rate which may vary depending on the region where the house is located is used, so that the reliability of the obtained remaining gas amount information can be further improved.
In the above invention, the surplus calculation unit may calculate an average value of the usage amount of the gas in a predetermined period for each of the demand houses based on the measurement result of the flow measurement unit, estimate a future usage amount of the gas after the end of the predetermined period for each of the demand houses based on the average value, and estimate a future surplus of the gas in the gas container after the end of the predetermined period for each of the demand houses.
According to the above configuration, the future usage amount of the gas after the predetermined period is completed and the future remaining amount of the gas in the gas container after the predetermined period is completed can be estimated based on the usage trend of the gas in the predetermined period. Thus, highly reliable estimation results of the future use amount of the fuel gas and estimation results of the future surplus amount of the fuel gas can be obtained.
In the above invention, the margin calculation unit may have an artificial intelligence function, and the margin calculation unit may estimate, for each of the demand houses, a future usage amount of the gas in the gas container after the end of the predetermined period based on a measurement result of the flow rate measurement unit in the predetermined period, and may estimate, for each of the demand houses, a future margin of the gas in the gas container after the end of the predetermined period, by the artificial intelligence function.
According to the above configuration, since artificial intelligence is used, the reliability of the estimation result of the future usage amount of the fuel gas and the estimation result of the future surplus amount of the fuel gas can be improved.
In the above invention, the replacement time estimating unit may estimate, as the replacement time of the gas container, a time when the remaining amount of the gas in the gas container calculated by the remaining amount calculating unit becomes smaller than the threshold value, using a threshold value determined based on an actual value of the usage amount of the gas in the demand house per day.
When a time when the remaining amount of the fuel gas reaches, for example, 10% of the volume of the fuel gas container is uniformly set as a replacement time, fuel gas exhaustion is likely to occur when sudden fuel gas consumption occurs in a demand house. In contrast, according to the above configuration, since the replacement time is estimated using the threshold value of the actual result value based on the amount of fuel gas used in one day, fuel gas exhaustion is less likely to occur when sudden fuel gas consumption occurs in the demand house.
In the above invention, the notification unit may use an average value of the usage amounts of the fuel gas in the demand house for a predetermined period as the fuel gas usage assumption condition.
According to the above configuration, the notification unit can easily detect sudden fuel gas consumption in the demand house.
ADVANTAGEOUS EFFECTS OF INVENTION
According to the present invention, it is possible to provide a gas balance management system that is less likely to cause gas exhaustion when sudden gas exhaustion occurs in a demand house.

Detailed Description
Next, a gas balance management system according to an embodiment of the present invention will be described with reference to the drawings. The gas balance management system described below is merely one embodiment of the present invention. Accordingly, the present invention is not limited to the following embodiments, and can be added, deleted, and modified within a range not departing from the gist of the present invention.
Fig. 1 is a block diagram showing a gas balance management system 100 according to the present embodiment, and fig. 2 is a block diagram showing detailed configurations of a demand house 20 and a center server 10 in the gas balance management system 100 of fig. 1.
As shown in fig. 1, the gas balance management system 100 includes a central server 10 and a plurality of demand residences 20. In addition, although four demand houses 20 are illustrated in fig. 1, in the gas balance management system 100, the demand houses 20 may be three or less, or five or more.
As shown in fig. 2, each demand house 20 is provided with a switch 12, a gas meter 13, two gas containers 11, and two gas facilities 14. The gas meter 13 corresponds to a flow rate measuring unit. Examples of the demand house 20 include hospitals, schools, autonomous facilities, nursing facilities, ordinary households, business facilities, and the like, but are not limited to these, and any building can be used as long as it can use fuel gas.
The gas container 11 is also called a gas tank, and the gas container 11 is filled with a gas such as LP gas (liquefied petroleum gas). In the following description, LP gas will be abbreviated as gas. The switch 12 is configured to switch the gas supply path so that the gas in one of the two gas tanks 11 is supplied to the demand house 20. Thus, even if the gas in one of the two gas containers 11 is exhausted, the gas in the other gas container 11 can be supplied to the gas facility 14.
The above-described gas exhaustion is defined as follows. In the present embodiment, the gas exhaustion refers to the following cases: if the gas container 11 to be used is switched by the switch 12, the gas container 11 used until the switching is in a state of being depleted of gas. In this case, the switch 12 detects a change in pressure applied to the inside of the gas container 11 to switch the gas container 11. Specifically, the switch 12 applies pressure to the gas container 11 to fill the gas, and if the gas is exhausted, the pressure drops. The switch 12 detects the change in the pressure, and switches the gas container 11 at the timing when the pressure drops. Thus, the gas can be regarded as being exhausted according to the pressure drop detected by the switch 12. In addition, the exhaustion of the gas also includes a case where the gas container 11 is manually switched when the pressure drops and the gas device 14 is no longer used. The gas exhaustion includes not only a pressure drop but also a case where, for example, a margin obtained by subtracting the used gas flow from the assumed gas capacity becomes 0 or a value in the vicinity of 0. These definitions apply to the depletion of fuel gas in both fuel gas containers 11.
The gas meter 13 measures the flow rate of the gas supplied to each gas device 14. The gas meter 13 may shut off the gas supply path by the shut-off portion when some abnormality is detected.
The gas meter 13 has a communication unit 13a. The communication unit 13a has a function of communicating with the center server 10 by wireless. As a wireless communication system between the communication unit 13a and the center server 10, for example, a communication network such as the internet, LAN, or LPWA (Low Power Wide Area: low power wide area network) can be used. The communication unit 13a periodically transmits information on the amount of fuel gas used in the demand house 20 to the center server 10 together with date information on the use, ID for specifying the demand house 20, and information on the location of the demand house 20.
The gas appliance 14 is, for example, a gas range, a gas water heater, a gas warm air blower, or the like, but is not limited to these, and may be any appliance that consumes gas.
In the present embodiment, the center server 10 includes a margin calculation unit 1, a replacement time estimation unit 2, a notification unit 3, a storage unit 4, and a communication unit 5. The remaining amount management unit 1, the replacement time estimation unit 2, and the notification unit 3 among the above-described components of the center server 10 realize their functions by a microcontroller including a CPU (Central Processing Unit: central processing unit) and a Memory (ROM (Read Only Memory) and RAM (Random Access Memory: random access Memory)) in which programs are stored, an ASIC (Application Specific Integrated Circuit: application specific integrated circuit), or the like. As the storage unit 4, various memories, hard disks, and the like can be used.
The remaining amount calculating unit 1 periodically receives the measurement results of the usage amount of the gas transmitted from the communication unit 13a of the gas meter 13 of each demand house 20 via the communication unit 5. The remaining amount calculating unit 1 calculates the remaining amount of the gas in the gas container 11 from the measurement result based on the gas container setting information given to each demand house 20. The above-described gas container setting information is information indicating the number of houses of the demand house 20 corresponding to one gas container 11. In fig. 2, two gas containers 11 are provided, but the number of houses 20 corresponding to one gas container 11 is one. Further, the manner in which the number of units of the demand house 20 corresponding to one gas container 11 is a plurality of units will be described later.
In the present embodiment, the margin calculation unit 1 has an artificial intelligence 1a. The margin calculation unit 1 estimates, for each demand house 20, the future usage amount of the gas after the completion of the predetermined period based on the measurement result of the gas meter 13 in the predetermined period by the artificial intelligence 1a. In this case, the average usage amount of the fuel gas in a predetermined number of days can be calculated, the calculated average usage amount can be classified into one of a plurality of groups, and the future usage amount of the fuel gas can be estimated for each demand house 20 based on the logic (operation formula) corresponding to each group. Then, the margin calculation unit 1 estimates the future margin of the gas in the gas container 11 after the predetermined period is completed for each demand house 20 by the artificial intelligence 1a. In this case, the average remaining amount of the fuel gas in a predetermined number of days is calculated, the calculated average remaining amount is classified into one of a plurality of groups, and the future remaining amount of the fuel gas is estimated for each demand house 20 based on a logic (operation formula) corresponding to each group.
Alternatively, the remaining amount calculating unit 1 may calculate an average value of the usage amount of the gas in a predetermined period for each demand house 20 based on the measurement result of the gas meter 13. For example, the remaining amount calculating unit 1 can calculate the average value by dividing the cumulative value of the usage amounts of the fuel gas in the past seven days by 7 days. Then, the remaining amount calculation unit 1 estimates the future usage amount of the gas after the end of the predetermined period for each demand house 20 based on the calculated average value, and estimates the future remaining amount of the gas in the gas container 11 after the end of the predetermined period for each demand house 20.
The remaining amount calculating unit 1 may use the gas yield when calculating the remaining amount of the fuel gas. In this case, the remaining amount calculation unit 1 calculates the remaining amount of the gas using the gas production rate corresponding to the region where the demand house 20 corresponding to the gas meter 13 from which the measurement result is transmitted is located, and the gas production rate corresponding to the date on which the measurement result of the gas meter 13 is obtained. This can further improve the reliability of the remaining gas amount information obtained by calculation. The details of the gas production rate will be described later.
The replacement time estimating unit 2 estimates the replacement time of the gas container 11 for each demand house 20 based on the calculation result of the remaining amount calculating unit 1. Specifically, the replacement time estimating unit 2 determines, as the replacement time of the gas container, a time when the remaining amount of the gas calculated by the remaining amount calculating unit 1 becomes less than a threshold value determined based on the actual result value of the usage amount of one day. As the actual result value of the usage amount per day, for example, an average value of the usage amount of the fuel gas in a predetermined period may be used. The replacement time estimating unit 2 estimates the replacement time of the gas container 11 when, for example, the remaining amount of gas in the gas container 11 reaches half the volume of the gas container 11, which is the estimated time of the replacement time.
The notification unit 3 receives information on the amount of gas used by the gas meter 13 of the demand house 20 via the communication unit 5. The notification unit 3 controls a display unit, a sound device, or the like to notify a warning, and performs a warning process for prompting a business who performs replacement of the gas container 11 to replace the gas container 11 when the usage amount of the gas exceeding the gas usage assumption condition is measured by the gas meter 13 in the demand house 20.
The gas use concept conditions in the present embodiment will be described. The gas use assumption condition can be determined for each demand house 20 and stored in the storage unit 4 in advance as an assumption condition table Tg. The estimated condition table Tg records, for example, an average value of the usage amounts of the fuel gas of the demand house 20 within a predetermined period. Specific examples are described below.
Fig. 3 is a diagram showing a concept condition table Tg of gas use concept conditions. In the assumed condition table Tg of fig. 3, demand houses a to C are described so as to identify three demand houses 20, respectively.
As shown in fig. 3, as the gas usage assumption condition for the demand house a, for example, an average value of the usage amount of gas in the past week is used. As the gas use assumption condition for the demand house B, for example, an average value of the gas use amount in the past month can be used. As the gas usage assumption conditions for the demand house C, for example, an average value of the usage amounts of gas in the same week in the past three years or an average value of the usage amounts of gas in days of the same air temperature in the past three years can be used. As described above, for a demand house a, for example, a home, in which the use of gas can be confirmed almost every day, an average value in a relatively short period can be used as a gas use assumption condition. For example, for a demand house B such as one made up of a single person, in which it is difficult to confirm the use of gas almost every day due to an overnight business trip or the like, an average value in a period relatively medium can be adopted as the gas use assumption condition. Further, as the gas use concept conditions, an average value of gas use amounts in a predetermined season in the past years, an average value of gas use amounts in days of the same air temperature (for example, ±5 ℃) in the past years, an average value of gas use amounts in days of the same weather in the past years, or the like can be adopted for the demand house C in which the use of gas is hardly confirmed because the building is, for example, a villa. These gas use concept conditions are examples, and are not limited to the above conditions.
The storage unit 4 stores the threshold value, the estimated condition table Tg, and the table in which the gas production rate of the gas is recorded, etc., which are used when the replacement time estimation unit 2 estimates the replacement time.
Since the gas production rate of the fuel gas is a value that may vary depending on the air temperature, the storage unit 4 stores the gas production rate of each of the four regions, for example. For example, the gas production rate in the case where the region where the house 20 is required is the first region including Hokkaido, qingsen, yankee and autumn fields is 4.69m 3 10kg. The gas production rate in the case where the area where the house 20 is required is a second area including a city, a mountain shape, a foodland, a new, a mountain, and a stone, is 4.78m 3 10kg. In addition, the gas production rate in the case where the region where the house 20 is required is a third region including a washline is 4.80m 3 10kg. And the area where the demand house 20 is located includes the above autonomyThe gas production rate in the case of the fourth region of the county of the other prefecture was 4.82m 3 /10kg。
The storage unit 4 may store the gas production rate of the gas in association with not only the above-described region but also the date. In this case, for example, the spring gas production rate, the summer gas production rate, the autumn gas production rate, and the winter gas production rate may be determined for each of the first to fourth regions. This makes it possible to further distinguish the gas production rates in the respective regions according to seasons.
The communication unit 5 periodically receives information of the amount of gas used, which is transmitted from the communication unit 13a of the gas meter 13, to which the location information of the demand house 20 and the ID for specifying the demand house 20 and the date information of using the gas are added.
Fig. 4 is a block diagram showing a mode in which one gas container 11 corresponds to a plurality of demand houses 20.
As shown in fig. 4, one gas container 11 corresponds to the gas meters 13 of the plurality of demand houses 20A. In this case, the remaining amount calculating section 1 calculates the remaining amount of the gas in the gas container 11 from the sum of the measurement results obtained from the plurality of gas meters 13.
As described above, according to the gas balance management system 100 of the present embodiment, the replacement time estimating unit 2 estimates the replacement time of the gas container 11 for each demand house 20. When the amount of fuel gas exceeding the fuel gas usage assumption condition is measured in the demand house 20, that is, when sudden fuel gas consumption occurs in the demand house 20, the notification unit 3 notifies the sudden fuel gas consumption. This allows the service provider to take care of, for example, replacement of the gas container 11 in advance. Thus, when sudden gas consumption occurs in the demand house 20, gas consumption is less likely to occur.
