Description

The present disclosure relates to an ozone amount calculation device for calculating the remaining amount of ozone, an ozone storage container, and a method for calculating the residual ozone amount.

Sterilization, cleaning and deodorization using ozone have been widely used in recent years. Patent Document 1 discloses a technique of operating an ozone generator at night when electricity charges are low to store ozone and using the stored ozone in the daytime to reduce operating costs.

Japanese Unexamined Patent Publication No. 9-235103

Conventionally, it is necessary to introduce, for example, an ozone generator as described in Patent Document 1 in an ozone utilization facility that utilizes ozone. However, it may not be easy to introduce an ozone generator in a facility where ozone is used infrequently or in a facility where ozone consumption is low from the viewpoint of cost. Therefore, there is a need to use ozone without installing an ozone generator in the ozone utilization facility.

As a method of using ozone without installing an ozone generator in an ozone utilization facility, the storage container is filled with ozone generated by an ozone generator managed by a business operator other than the user who uses ozone, and the storage container is filled with ozone. A method of using the stored ozone at an ozone utilization facility is conceivable. In this case, the user cannot use the ozone when the ozone stored in the storage container is depleted. In addition, ozone is easily self-decomposed, and self-decomposition depends on the storage environment such as temperature. Therefore, if the ozone storage container is stored in an inappropriate storage environment for a certain period of time or longer, the remaining amount of ozone sharply decreases. Therefore, it is desirable that the ozone storage container be properly managed.

The present disclosure has been made in view of the above, and an object of the present invention is to obtain an ozone amount calculation device capable of supporting appropriate management of an ozone storage container.

In order to solve the above-mentioned problems and achieve the purpose, the ozone amount calculation device according to the present disclosure uses information indicating the storage environment of the ozone storage container installed in the ozone utilization facility using ozone to self-ozone. It is provided with a self-decomposition amount calculation unit that calculates the decomposition rate and calculates the self-decomposition amount using the self-decomposition rate and the installation date of the ozone storage container. The ozone amount calculation device further reflects the self-decomposition amount by using the remaining amount information indicating the remaining amount of ozone in the ozone storage container reflecting the amount of ozone consumed in the ozone utilization facility and the self-decomposition amount. It is provided with a residual ozone amount calculation unit for calculating the residual ozone amount, which is the remaining amount of ozone in the ozone storage container, and an output unit for outputting the residual ozone amount.

The ozone amount calculation device according to the present disclosure has the effect of being able to support the appropriate management of the ozone storage container.

Hereinafter, the ozone amount calculation device, the ozone storage container, and the residual ozone amount calculation method according to the embodiment will be described in detail with reference to the drawings.

Embodiment 1.
FIG. 1 is a diagram showing a configuration example of the ozone management system according to the first embodiment. The ozone management system 3 of the present embodiment includes an ozone amount calculation device 1 and an ozone storage container 2. The ozone management system 3 may include a user terminal 4.

The ozone storage container 2 of the present embodiment is installed in an ozone utilization facility that utilizes ozone, and can store ozone generated by an ozone generator (not shown). The ozone stored in the ozone storage container 2 is used in ozone utilization facilities, for example, for sterilization, cleaning, deodorization, etc., but the use of ozone is not limited thereto. The ozone utilization facility is not equipped with an ozone generator. For example, the ozone storage container 2 is filled with ozone by an ozone generator in an ozone generation facility (not shown), and the ozone-filled ozone storage container 2 uses ozone. It is brought into the facility. Alternatively, when ozone needs to be supplied at the ozone utilization facility, for example, the ozone generator is brought into the ozone utilization facility by a business operator that rents the ozone generator, and the ozone generator puts ozone into the ozone storage container 2. May be supplied. In this case, the ozone generator is returned after the ozone is supplied.

Further, ozone is easily self-decomposed and has a short life, so that it is difficult to store it. However, in the present embodiment, for example, the ozone storage container 2 is filled with an adsorbent such as silica gel and maintained at a low temperature to adsorb it. Ozone and oxygen are separated from the mixed gas containing ozone and oxygen by utilizing the difference in the adsorption and desorption characteristics of ozone and oxygen with respect to the agent. As a result, the ozone storage container 2 can suppress the autolysis of ozone.

The ozone storage container 2 includes a display device 21, a temperature measuring device 22, and a remaining amount measuring device 23. The display device 21 can receive the residual ozone amount, which is the remaining amount of ozone in the ozone storage container 2, from the ozone amount calculation device 1, and display the received residual ozone amount. The temperature measuring device 22 is provided in the ozone storage container 2, and can measure the temperature of the ozone storage container 2 and transmit the measured value of the temperature as measurement information to the ozone amount calculation device 1. The remaining amount measuring device 23 can measure the remaining amount of ozone stored in the ozone storage container 2 with a pressure gauge or the like, and transmit the measured value of the remaining amount of ozone to the ozone amount calculation device 1 as measurement information. Is.

The ozone amount calculation device 1 calculates the residual ozone amount, which is the remaining amount of ozone in the ozone storage container 2. Ozone is easily autolyzed, and the autolysis rate depends on the ozone storage environment such as temperature. On the other hand, since ozone becomes oxygen when it self-decomposes, even if the ozone storage container 2 is provided with the remaining amount measuring device 23, the amount of ozone self-decomposed for the measurement of the remaining amount measuring device 23 using a pressure gauge or the like. Is not reflected. Therefore, even if the user confirms the measured value of the remaining amount measuring device 23, the remaining amount of ozone cannot be correctly grasped. The ozone amount calculation device 1 of the present embodiment calculates the self-decomposition amount according to the ozone storage environment, and reflects the calculated self-decomposition amount to determine the residual ozone amount which is the remaining amount of ozone in the ozone storage container 2. By calculating and outputting the calculated residual ozone amount, the residual ozone amount is presented to the user. As a result, the user can grasp the residual ozone amount more accurately than when the self-decomposition amount is not taken into consideration, such as ordering the ozone storage container 2 filled with ozone or requesting the introduction of the ozone generator. Can be prepared for. In this way, the ozone amount calculation device 1 can support the appropriate management of the ozone storage container 2.

Next, a configuration example of the ozone amount calculation device 1 will be described. The ozone amount calculation device 1 includes a measurement information acquisition unit 11, an autolysis amount calculation unit 12, a residual ozone amount calculation unit 13, an output unit 14, a facility information storage unit 15, and a facility information acquisition unit 16.

The measurement information acquisition unit 11 acquires measurement information by receiving measurement information from the temperature measuring device 22 and the remaining amount measuring device 23, which are the measuring devices in the ozone storage container 2. Of the acquired measurement information, the measurement information acquisition unit 11 outputs the temperature measurement information to the self-decomposition amount calculation unit 12, and outputs the measurement information of the remaining amount of ozone to the residual ozone amount calculation unit 13.

The facility information acquisition unit 16 acquires facility information by receiving facility information, which is information about an ozone-using facility in which the ozone storage container 2 is stored, from the user terminal 4, and the acquired facility information is stored in the facility information storage unit 15. Store in. The facility information storage unit 15 stores facility information. The facility information includes, for example, information such as an initial concentration which is an ozone concentration when the ozone storage container 2 is fully filled, an installation date indicating a date when the ozone storage container 2 is installed, and the like. The installation date when the ozone storage container 2 is installed is the day when the ozone storage container 2 is carried in when the ozone-filled ozone storage container 2 is carried into the ozone utilization facility, and the ozone generator is ozone. When ozone is supplied to the ozone storage container 2 when it is carried into the facility and the ozone utilization facility is used, it is the day when ozone is supplied to the ozone storage container 2. The initial concentration is the concentration of ozone on the day of installation. The installation date is an example of the installation date and time. That is, the installation date and time may be indicated as a date in units of days or may be indicated by a date and time. If the ozone-filled ozone storage container 2 is brought in or ozone is supplied to the ozone storage container 2 in the ozone utilization facility multiple times, that is, if there are multiple installation dates, the facility information is included. Stores the latest installation date.

The self-decomposition amount calculation unit 12 calculates the self-decomposition rate of ozone using the information indicating the storage environment of the ozone storage container 2, and calculates the self-decomposition amount using the self-decomposition rate and the installation date and time of the ozone storage container 2. do. Specifically, the autolysis amount calculation unit 12 calculates the autolysis rate of ozone using the measurement information of the temperature received from the measurement information acquisition unit 11, and the calculated autolysis rate and the elapsed time from the installation date. And, the autolysis amount of ozone is calculated. The autolysis amount calculation unit 12 outputs the calculated autolysis amount to the residual ozone amount calculation unit 13. The measurement information measured by the temperature measuring device 22 is an example of information indicating the storage environment. Hereinafter, the temperature measurement information is also referred to as temperature measurement information. The method of calculating the amount of autolysis will be described later.

The residual ozone amount calculation unit 13 uses the remaining amount information indicating the remaining amount of ozone in the ozone storage container 2 reflecting the amount of ozone consumed in the ozone utilization facility and the self-decomposition amount to determine the self-decomposition amount. The amount of residual ozone, which is the remaining amount of ozone in the reflected ozone storage container 2, is calculated. Specifically, the residual ozone amount calculation unit 13 uses the measurement information of the remaining amount of ozone received from the measurement information acquisition unit 11 and the self-decomposition amount output from the self-decomposition amount calculation unit 12. The amount of ozone is calculated, and the calculated amount of residual ozone is output to the output unit 14. That is, the measurement information acquired by the measurement information acquisition unit 11 is an example of the remaining amount information indicating the remaining amount of ozone in the ozone storage container 2 reflecting the amount of ozone consumed in the ozone utilization facility. Hereinafter, the measurement information of the remaining amount of ozone is also referred to as the remaining amount measurement information. In detail, the residual ozone amount calculation unit 13 calculates the residual ozone amount by subtracting the self-decomposition amount from the remaining amount indicated by the remaining amount measurement information received from the measurement information acquisition unit 11.

The output unit 14 outputs the residual ozone amount by transmitting the residual ozone amount to the display device 21 and the user terminal 4. In FIG. 1, the output unit 14 transmits the residual ozone amount to the display device 21 and the user terminal 4, but the output unit 14 transmits the residual ozone amount to one of the display device 21 and the user terminal 4. You may. When the output unit 14 transmits the residual ozone amount only to the user terminal 4, the ozone storage container 2 does not have to include the display device 21. The output unit 14 may notify the user terminal 4 of the residual ozone amount when the residual ozone amount becomes equal to or less than a predetermined threshold value. The threshold value may be set as a plurality of values having different values. For example, when a first threshold value and a second threshold value smaller than the first threshold value are set and the residual ozone amount becomes equal to or less than the first threshold value, and the residual ozone amount is the first. When the threshold value of 2 or less is reached, the output unit 14 may notify the user terminal 4 of the amount of residual ozone. For example, the output unit 14 may generate an e-mail notifying the amount of residual ozone and send the generated e-mail to the user terminal 4. Further, the output unit 14 may transmit the residual ozone amount to the user terminal 4 by the application software of the SNS (Social Networking Service).

The user terminal 4 is, for example, a terminal such as a smartphone, a tablet, or a personal computer. When the user terminal 4 receives the residual ozone amount from the ozone amount calculation device 1, the user terminal 4 displays the residual ozone amount. For example, application software for displaying the residual ozone amount in the ozone storage container 2 may be installed in the user terminal 4, and the application software may display the residual ozone amount. Further, when the user terminal 4 receives the residual ozone amount by e-mail, the user terminal 4 displays the residual ozone amount by application software having an e-mail transmission / reception and display function. When the user terminal 4 receives the residual ozone amount by the SNS application software, the user terminal 4 displays the residual ozone amount by the SNS application software.

FIG. 2 is a diagram showing a configuration example of the ozone storage container 2 of the present embodiment. The ozone storage container 2 includes a container body 24 for storing ozone. The container body 24 is the same as a container used as a general gas cylinder. Further, as described with reference to FIG. 1, the ozone storage container 2 includes a display device 21, a temperature measuring device 22, and a remaining amount measuring device 23. Further, the ozone storage container 2 may have a cooling function for cooling the container body 24. For example, the container main body 24 may have a structure in which a refrigerant flows or is filled between the outer wall and the inner wall of the container to cool the inside of the container, or a cooling device can be connected or mounted on the outside of the container. The cooling device may be an electronic cooling device such as a Pelche element, or may be a cooling jacket such as a cold insulating material. The cooling method of the ozone storage container 2 is not limited to these.

Further, as the container shape of the container body 24, various containers such as a high-pressure gas cylinder or a simple container such as a spray can can be used depending on the ozone filling amount (number of days of use). In the case of the gas cylinder type, it is desirable, but not limited to, two types of cylinder ports, a carrier gas inlet port and a pump extraction port, to be installed. Further, when the material of the container body 24 is stainless steel or aluminum, ozone decomposition due to contact with the inner wall of the container or friction can be prevented. Further, when the inner surface of the container is smooth, it is possible to prevent ozone decomposition due to contact with the inner wall of the container or friction. The material and shape of the container body 24 are not limited to this. Further, if the inner metal of the container body 24 is passivated in advance by ozone treatment or the like, ozone decomposition due to contact or friction can be further prevented.

In the ozone storage container 2, for example, ozone is adsorbed in the adsorbent at high pressure during filling. When taking out ozone, for example, carrier gas is introduced into the ozone storage container 2 from the outside to desorb ozone and take it out, or ozone is pulled out from the container with a pump or the like without introducing carrier gas to desorb it. Or, ozone is taken out to the outside by using both. The ozone filling method and extraction method are not limited to this example. In the ozone storage container 2, it is desirable to keep a high pressure of atmospheric pressure or higher.

The display device 21 includes a display unit 211 and a communication unit 212. The communication unit 212 receives the residual ozone amount from the ozone amount calculation device 1, and outputs the received residual ozone amount to the display unit 211. The display unit 211 is, for example, a display such as a liquid crystal display, and displays the amount of residual ozone.

The temperature measuring device 22 includes a temperature measuring unit 221 and a communication unit 222. The temperature measurement unit 221 measures the temperature of the ozone storage container 2 and outputs measurement information indicating the measured temperature to the communication unit 222. The communication unit 222 transmits the measurement information to the ozone amount calculation device 1.

The remaining amount measuring device 23 includes a remaining amount measuring unit 231 and a communication unit 232. The remaining amount measuring unit 231 is a pressure gauge or the like that measures the remaining amount of the ozone storage container 2, and outputs measurement information indicating the measured remaining amount to the communication unit 232. The communication unit 232 transmits the measurement information to the ozone amount calculation device 1.

Instead of the temperature measuring device 22 of the ozone storage container 2, the measured value of the temperature of the place where the ozone storage container 2 is stored may be used. FIG. 3 is a diagram showing an example of the ozone storage chamber of the present embodiment. In the example shown in FIG. 3, a plurality of ozone storage containers 2 are stored in the ozone storage chamber 5, and the temperature inside the ozone storage chamber 5, that is, the temperature at the storage location of the ozone storage container 2 is measured in the ozone storage chamber 5. A temperature measuring device 51 is provided. The temperature measuring device 51 transmits the measured temperature as temperature measurement information to the ozone amount calculation device 1. Further, for example, it is assumed that the ozone in the ozone storage container 2 is not used while being stored in the ozone storage chamber 5, and when ozone is used, the ozone storage container 2 is taken out from the ozone storage chamber 5. Further, it is assumed that the ozone storage container 2 is returned to the ozone storage chamber 5 after the use of ozone.

In the case of the above-mentioned usage method, since the ozone in the ozone storage container 2 is not used in the ozone storage chamber 5, the ozone amount calculation device 1 does not have to acquire the remaining amount measurement information. That is, the residual ozone amount calculation unit 13 may calculate the residual ozone amount by subtracting the self-decomposition amount from the capacity of the ozone storage container 2. Even when the ozone storage container 2 is stored in the ozone storage chamber 5, the remaining amount measuring device 23 measures the remaining amount of ozone and the measured value is used as the remaining amount measurement information, as in the example shown in FIG. The ozone amount may be transmitted to the ozone amount calculation device 1 and the residual ozone amount calculation unit 13 may calculate the residual ozone amount by subtracting the self-decomposition amount from the remaining amount indicated by the remaining amount measurement information.

In the case of the above example, the temperature of the ozone storage container 2 changes when it is used, but if it is a short time, it is not necessary to consider the change in the amount of autolysis due to the temperature change during that period. Alternatively, one removable temperature measuring device 22 may be prepared, and the temperature measuring device 22 may be attached to the ozone storage container 2 to be used. In the latter case, the ozone amount calculation device 1 calculates the self-decomposition amount of the ozone storage container 2 used by using the temperature measurement information of the temperature measurement device 22.

The ozone storage chamber 5 may be a place kept at a low temperature such as a refrigerating room or a freezing room, or may be a place kept at a certain low temperature by an air conditioner or the like. The ozone storage chamber 5 does not have to be a dedicated space for storing ozone, and the ozone storage container 2 may be installed in the existing space, and the temperature measuring device 51 may be provided in the space.

Further, when the amount of ozone used per unit time is predetermined, or when the amount of ozone used is controlled by a control device (not shown), the ozone storage container 2 is provided with the remaining amount measuring device 23. It does not have to be. In this case, the ozone amount calculation device 1 acquires, for example, the amount of ozone used per unit time by input from the operator. Alternatively, the ozone amount calculation device 1 periodically acquires the usage amount from a control device (not shown). When the amount of ozone used per unit time is input, the residual ozone amount calculation unit 13 indicates the elapsed time from the installation date when the ozone storage container 2 in the facility information is installed in the amount of ozone used per unit time. By multiplying by, the cumulative usage from the installation date is calculated. Then, the residual ozone amount calculation unit 13 calculates the residual ozone amount by subtracting the calculated cumulative usage amount and the self-decomposition amount from the capacity of the ozone storage container 2. In this way, instead of the remaining amount measurement information as the remaining amount information indicating the remaining amount of ozone in the ozone storage container 2 reflecting the amount of ozone consumed in the ozone utilization facility, the capacity of the ozone storage container 2 and the installation Information indicating the remaining amount of ozone in the ozone storage container 2 calculated using the date and time and the amount of ozone consumed per unit time may be used. When the usage amount is periodically acquired from a control device (not shown), the residual ozone amount calculation unit 13 uses the acquired usage amount and uses it from the installation date when the ozone storage container 2 in the facility information is installed. Calculate the cumulative value of the quantity. Then, the residual ozone amount calculation unit 13 calculates the residual ozone amount by subtracting the calculated cumulative usage amount and the self-decomposition amount from the capacity of the ozone storage container 2.

Next, the operation of this embodiment will be described. FIG. 4 is a flowchart showing an example of a procedure for calculating the residual ozone amount in the ozone amount calculation device 1 of the present embodiment. The ozone amount calculation device 1 acquires measurement information (step S1). Specifically, the measurement information acquisition unit 11 acquires the temperature measurement information and the remaining amount measurement information, outputs the acquired temperature measurement information to the autolysis amount calculation unit 12, and outputs the remaining amount measurement information to the residual ozone amount calculation unit 13. Output to. The temperature measurement information may be the measurement information of the temperature measuring device 22 of the ozone storage container 2 or the measurement information of the temperature measuring device 51 for measuring the temperature of the storage location of the ozone storage container 2. That is, the information indicating the storage environment of the ozone storage container 2 may be the measurement information measured by the temperature measuring device 51 that measures the temperature of the storage location of the ozone storage container 2. Further, when the storage location of the ozone storage container 2 is defined and the temperature of the storage location is defined, the temperature of the storage location may be used instead of the temperature measurement information. The temperature of the storage location may be input to the ozone amount calculation device 1 by the user, for example, or may be input to the user terminal 4 by the user and transmitted from the user terminal 4 to the ozone amount calculation device 1.

The ozone amount calculation device 1 calculates the self-decomposition amount according to the ozone storage environment using the temperature measurement information (step S2). Specifically, the autolysis amount calculation unit 12 calculates the autolysis rate of ozone using the temperature measurement information received from the measurement information acquisition unit 11, and the calculated autolysis rate and the elapsed time from the installation date. The self-decomposition amount of ozone is calculated using, and the calculated self-decomposition amount is output to the residual ozone amount calculation unit 13.

Next, an example of the method of calculating the autolysis rate will be described. In the following, an example of using the half-life as a value indicating the autolysis rate will be described. The autolysis amount calculation unit 12 calculates the half-life using the temperature measurement information and the half-life correspondence information indicating the relationship between the ozone temperature and the half-life.

The half-life correspondence information may be a calculation formula for calculating the half-life from the ozone temperature and initial concentration, or the initial concentration and temperature of ozone are divided into a plurality of categories, and the corresponding half-life is determined for each category. It may be determined by a table. A calculation formula for calculating the half-life from the temperature or a table showing the correspondence between the temperature and the half-life may be used without considering the initial concentration. Further, in an ozone utilization facility in which ozone is continuously supplied for a certain period of time, the flow velocity of ozone may be input and the half-life may be calculated in consideration of the flow velocity. The half-life correspondence information may be estimated in consideration of the reaction formula of ozone self-decomposition, or may be acquired in advance by a test or the like using an ozone-filled ozone storage container 2.

The half-life due to self-decomposition of ozone is th, the initial concentration when ozone is fully filled in the ozone storage container 2 is _C0 , and the time elapsed from the installation date when the ozone storage container 2 is fully filled is shown. Assuming that the current time is T and th / T is t, the self-decomposition amount C (T) at the current time T can be expressed by the following equation (1).
C (T) = C ₀ (1- (1/2) ^t ) ... (1)

The self-decomposition amount calculation unit 12 uses the installation date in the facility information stored in the facility information storage unit 15 to obtain T, which is the current time expressed as the elapsed time from the installation date. Then, the autolysis amount calculation unit 12 uses the obtained T, the calculated half-life, and the initial concentration in the facility information stored in the facility information storage unit 15 to determine the autolysis amount according to (1) above. calculate.

Next, the ozone amount calculation device 1 calculates the residual ozone amount using the remaining amount measurement information and the self-decomposition amount (step S3). Specifically, the residual ozone amount calculation unit 13 reduces the residual ozone amount received from the self-decomposition amount calculation unit 12 from the remaining amount indicated by the remaining amount measurement information received from the measurement information acquisition unit 11. calculate. The residual ozone amount calculation unit 13 outputs the calculated residual ozone amount to the output unit 14.

Next, the ozone amount calculation device 1 outputs the residual ozone amount (step S4). Specifically, as described above, the output unit 14 outputs the residual ozone amount by transmitting the residual ozone amount to at least one of the display device 21 and the user terminal 4. That is, the display device 21 and the user terminal 4 display the residual ozone amount calculated based on the self-decomposition amount of ozone calculated using the information indicating the storage environment of the ozone storage container 2. As a result, the user can grasp the amount of residual ozone in consideration of autolysis in the ozone storage container 2. Further, the residual ozone amount calculation unit 13 may instruct the output unit 14 to output an alarm when the residual ozone amount is equal to or less than the threshold value, and the output unit 14 may output the alarm.

Next, the hardware configuration of the ozone amount calculation device 1 of the present embodiment will be described.

The number of air supply ports and return air openings shown in FIG. 6 is an example, and the number of air supply ports and return air ports is not limited to this example.

At the time of heating, the air conditioner 8 generates hot air by heating the outside air and the return air from the sterilization target space 6 using the hot water generated by the heat source machine 9, and the generated hot air is used as a supply duct. It is supplied to the sterilization target space 6 via the 82 and the air supply grills 83-1 to 83-3. At the time of cooling, the air conditioner 8 generates cold air by cooling the outside air and the return air from the sterilization target space 6 using the cold water generated by the heat source machine 9, and the generated cold air is used in the air supply duct 82 and the air conditioner 8. It is supplied to the sterilization target space 6 via the air supply grills 83-1 to 83-3. The ozone storage container 2 may be stored in the ozone storage chamber 5.

The ozone storage container 2 supplies ozone to the air supply duct 82 based on the control from the control device 7. As a result, ozone is accompanied by the airflow generated by the air conditioner 8 and supplied to the sterilization target space 6. The control device 7 may control at least one of the wind direction and the air volume of the air supply grills 83-1 to 83-3 by transmitting a control signal to the air conditioner 8. In the example shown in FIG. 6, since ozone is sprayed to the sterilization target space 6 along with the air flow of the air conditioner 8, sterilization can be efficiently performed even in a wide space.

When the control device 7 controls the supply of ozone from the ozone storage container 2 as in the example shown in FIG. 6, the ozone amount calculation device 1 (not shown in FIG. 6) uses ozone from the control device 7. And, as described above, the residual ozone amount may be calculated using the acquired usage amount instead of the remaining amount measurement information. Further, the ozone amount calculation device 1 may be provided in the control device 7. Note that FIG. 6 is an example of how to use ozone stored in the ozone storage container 2, and the method of using ozone is not limited to the example shown in FIG.

FIG. 7 is a diagram showing an example of the ozone storage container 2 of the present embodiment incorporating the ozone amount calculation device 1. The ozone storage container 2a shown in FIG. 7 includes an ozone amount calculation device 1. In this case, the ozone amount calculation device 1 may be realized by, for example, a control circuit including a control unit 101, a storage unit 103, and a communication unit 105 shown in FIG. Further, in this case, the display device 21, the temperature measuring device 22, and the remaining amount measuring device 23 are not provided with the respective communication units 212, 222, 232, and the display unit 211, the temperature measuring unit 221 and the remaining amount measuring unit 231 are not provided.

I tried to present it. Thereby, the ozone amount calculation device 1 can support the appropriate management of the ozone storage container 2. Further, even if the remaining amount of ozone in the ozone storage container 2 is measured by the remaining amount measuring device 23 such as a pressure gauge, the self-decomposition amount is not reflected in the measurement result by the remaining amount measuring device 23. On the other hand, since the ozone amount calculation device 1 of the present embodiment calculates the residual ozone amount in consideration of the self-decomposition amount according to the storage environment, compared with the case where the self-decomposition amount is not considered. The amount of residual ozone can be calculated accurately. Further, the environment of the storage location of the ozone storage container 2 may differ depending on the user, such as a refrigerating room, a freezing room, or a room at room temperature.

Embodiment 2.
FIG. 8 is a diagram showing a configuration example of the ozone amount calculation device of the second embodiment. The ozone management system of the present embodiment is the same as the ozone management system 3 of the first embodiment except that the ozone amount calculation device 1a is provided instead of the ozone amount calculation device 1. The ozone amount calculation device 1a is the same as the ozone amount calculation device 1 of the first embodiment except that the expiration date calculation unit 17 is added. Components having the same functions as those of the first embodiment are designated by the same reference numerals as those of the first embodiment, and duplicate description will be omitted. Hereinafter, the differences from the first embodiment will be mainly described.

It is assumed that the ozone storage container 2 is stored in, for example, the ozone storage chamber 5 described in the first embodiment or another place, and is not used. In the present embodiment, the residual ozone amount calculation unit 13 outputs the half-life indicating the autolysis rate of ozone and the residual ozone amount to the expiration date calculation unit 17. The expiration date calculation unit 17 predicts the remaining amount of ozone in the ozone storage container 2 using the self-decomposition rate and the amount of residual ozone, and determines the expiration date of ozone stored in the ozone storage container 2 using the prediction result. do. Specifically, the residual ozone amount and the half-life are used to predict the residual ozone amount after the present time, and the prediction result is used to calculate the expiration date when the residual ozone amount is equal to or less than a predetermined threshold value. For example, when the expiration date calculation unit 17 has a half-life due to self-decomposition of ozone as th and the ozone concentration corresponding to the residual ozone amount received from the residual ozone amount calculation unit 13 is C ₁ , the elapsed time from the present time is set. _{Assuming that Ta is Ta and th / T a is} ta, the residual ozone amount C _a (T) is predicted by the following equation (2).
C _a (T) = C ₁ × (1/2) ^ta ... (2)

Alternatively, the residual ozone amount calculation unit 13 outputs the installation date, half-life, and initial concentration to the expiration date calculation unit 17, and the expiration date calculation unit 17 outputs the installation date, half-life, and initial concentration. May be used to predict the amount of residual ozone.

FIG. 9 is a flowchart showing an example of a procedure for calculating the residual ozone amount in the ozone amount calculation device 1a of the present embodiment. Steps S1 to S3 are the same as those in the first embodiment. After step S3, the ozone amount calculation device 1a predicts the residual ozone amount and calculates the expiration date using the prediction result (step S5). Specifically, as described above, the expiration date calculation unit 17 may predict the residual ozone amount using, for example, the residual ozone amount and the half-life, and the installation date, the half-life, and the initial concentration. May be used to predict the amount of residual ozone. The expiration date calculation unit 17 calculates the expiration date using the prediction result. The expiration date is, for example, the day when the residual ozone amount becomes equal to or less than the threshold value. The threshold value may be 0 or may be set to a value larger than 0 in consideration of prediction error and the like. The threshold may be set by the user. The expiration date calculation unit 17 and the expiration date are output to the output unit 14.

FIG. 10 is a schematic diagram showing an example of the prediction result of the residual ozone amount and the expiration date of the present embodiment. In FIG. 10, the horizontal axis represents time and the vertical axis represents the amount of residual ozone. As shown in FIG. 10, the amount of residual ozone decreases with the passage of time. Although the state of ozone decrease with respect to time due to autolysis is generally not a straight line, FIG. 10 is shown as a straight line because it is schematically shown. As shown in FIG. 10, the expiration date calculation unit 17 obtains the time point when the residual ozone amount becomes equal to or less than the threshold value as the expiration date. The expiration date may be indicated on a daily basis or by a date and time.

Next, the ozone amount calculation device 1a outputs the residual ozone amount and the expiration date (step S6). Specifically, the output unit 14 outputs the residual ozone amount and the expiration date by transmitting the expiration date together with the residual ozone amount to at least one of the display device 21 and the user terminal 4.

As a result, the user can grasp the amount of residual ozone in consideration of autolysis in the ozone storage container 2, and can grasp the expiration date when the amount of residual ozone is equal to or less than the threshold value. Therefore, the user can place an order for the ozone-filled ozone storage container 2 before the expiration date.

FIG. 11 is a diagram showing an example of a display screen displayed on the display device 21 of the present embodiment. In the example shown in FIG. 11, the amount of residual ozone is shown as a ratio (percentage) to the full amount. The method for displaying the residual ozone amount is not limited to this example, and the residual ozone amount itself may be indicated. Further, for example, the residual ozone amount may be indicated by displaying a bar-shaped figure and displaying the residual ozone amount in different colors corresponding to the residual ozone amount in the figure, or the meter figure and the indication of the residual ozone amount. A figure showing a value may be displayed, or the residual ozone amount may be displayed by a display method other than these. Further, in the example shown in FIG. 11, the expiration date is indicated by a date, but the expiration date may be indicated by a date and time, and for example, "the expiration date will be after A days". Alternatively, the number of days remaining until the expiration date may be indicated, such as "Ozone will be exhausted after A days".

In the example described above, the calculation of the expiration date when the ozone storage container 2 is stored in a state where ozone in the ozone storage container 2 is not used has been described. Next, the calculation of the expiration date when the ozone in the ozone storage container 2 is used will be described.

FIG. 12 is a flowchart showing an example of a procedure for calculating the residual ozone amount in the ozone amount calculation device 1a of the present embodiment when ozone is used. Steps S1 to S3 are the same as those in the first embodiment. After step S3, the ozone amount calculation device 1a predicts the residual ozone amount due to autolysis (step S7). Specifically, the expiration date calculation unit 17 predicts the residual ozone amount when only the self-decomposition amount is considered as the residual ozone amount due to autolysis, as in the prediction in step S5 shown in FIG. The expiration date calculation unit 17 may predict the amount of residual ozone due to self-decomposition by using, for example, the amount of residual ozone and the half-life, or by self-decomposition using the installation date, the half-life, and the initial concentration. The amount of residual ozone may be predicted.

The ozone amount calculation device 1a predicts the consumption amount using the remaining amount measurement information (step S8). The residual ozone amount calculation unit 13 also outputs the remaining amount measurement information to the expiration date calculation unit 17. The expiration date calculation unit 17 stores the remaining amount measurement information, and predicts the ozone consumption by using the stored remaining amount measurement information. For example, the expiration date calculation unit 17 uses the remaining amount measurement information for a certain period from the reference time to reduce the remaining amount indicated by the remaining amount measurement information corresponding to each time from the remaining amount indicated by the remaining amount measurement information at the reference time. By doing so, the consumption amount corresponding to each time is calculated. The expiration date calculation unit 17 obtains a calculation formula for predicting the consumption amount at each time after the present time by regression analysis or the like using the consumption amount at each time within a certain period. Then, the expiration date calculation unit 17 predicts the consumption amount using the obtained calculation formula. Alternatively, the expiration date calculation unit 17 calculates the average ozone consumption, which is the average value of the consumption per unit time, using the consumption within a certain period, and multiplies the average ozone consumption by the elapsed time from the present time. By doing so, the consumption may be predicted.

Here, an example of predicting the consumption amount using the remaining amount measurement information has been described, but the present invention is not limited to this, and for example, the average ozone consumption amount, which is the average value of the ozone usage amount per unit time from the user, is calculated. It is input to the ozone amount calculation device 1a, and the expiration date calculation unit 17 may predict the ozone consumption amount using the average ozone consumption amount. Further, when the ozone usage interval and the one-time usage amount are determined, the usage interval and the one-time usage amount are input by the user to the ozone amount calculation device 1a, and the expiration date calculation unit 17 determines. Ozone consumption may be predicted using the interval of use and the amount of one-time use. Further, for example, when the pattern of using ozone for a certain period at night and not using it for other periods is repeated, the user inputs information indicating this pattern to the ozone amount calculation device 1a, and the expiration date is reached. The calculation unit 17 may predict the consumption amount using the pattern.

After step S8, the ozone amount calculation device 1a predicts the residual ozone amount using the prediction result of the residual ozone amount by self-decomposition and the prediction result of the consumption amount, and sets the expiration date using the prediction result of the residual ozone amount. Calculate (step S9). Specifically, the expiration date calculation unit 17 predicts the residual ozone amount by subtracting the prediction result of the consumption amount obtained in step S8 from the prediction result of the residual ozone amount obtained by self-decomposition in step S7 for each time. do. The expiration date calculation unit 17 uses the prediction result of the residual ozone amount to obtain the expiration date when the residual ozone amount is equal to or less than the threshold value, and outputs the obtained expiration date to the output unit 14. Step S6 is similar to the example shown in FIG. In this way, the expiration date calculation unit 17 predicts the remaining amount of ozone in the ozone storage container 2 using the amount of ozone consumed per unit time, the self-decomposition rate, and the amount of residual ozone, and uses the prediction result to predict ozone. The expiration date of ozone stored in the storage container 2 may be determined.

FIG. 13 is a schematic diagram showing an example of a prediction result of the residual ozone amount and an expiration date of the present embodiment when ozone is used. In FIG. 13, the horizontal axis represents time and the vertical axis represents the amount of residual ozone. As shown in FIG. 13, the amount of residual ozone decreases due to both autolysis and use during the period when ozone is used, and the amount of residual ozone decreases due to autolysis during the period when ozone is not used. Although the state of ozone decrease with respect to time due to autolysis is generally not a straight line, FIG. 13 is shown as a straight line because it is schematically shown. As shown in FIG. 13, the expiration date calculation unit 17 obtains the time point when the residual ozone amount becomes equal to or less than the threshold value as the expiration date.

Further, the expiration date calculation unit 17 may instruct the output unit 14 to output an alarm when the time until the expiration date is equal to or less than a predetermined value, and the output unit 14 may output the alarm.

The ozone amount calculation device 1a of the present embodiment can also be realized by, for example, the computer system illustrated in FIG. 5, similarly to the ozone amount calculation device 1 of the first embodiment. Further, the ozone storage container 2 may be provided with the ozone amount calculation device 1a, as in the example shown in FIG.

The ozone amount calculation device 1a of the present embodiment calculates not only the residual ozone amount but also the expiration date, and outputs the expiration date as well. Thereby, the ozone amount calculation device 1a can support the appropriate management of the ozone storage container 2.

In this embodiment, both the residual ozone amount and the expiration date are calculated and both are output, but only the expiration date may be calculated and output. For example, regarding the ozone storage container 2 that is stored without being used, for example, the user can consider the schedule of ordering ozone by confirming the expiration date, and appropriately manage the ozone storage container 2. It can be performed.

Embodiment 3.
FIG. 14 is a diagram showing a configuration example of the ozone amount calculation device of the third embodiment. The ozone management system of the present embodiment is the same as the ozone management system 3 of the first embodiment except that the ozone amount calculation device 1b is provided in place of the ozone amount calculation device 1 and the alarm device 52 is added. The ozone amount calculation device 1b is the same as the ozone amount calculation device 1 of the first embodiment except that the monitoring unit 18 is added. Components having the same functions as those of the first embodiment are designated by the same reference numerals as those of the first embodiment, and duplicate description will be omitted. Hereinafter, the differences from the first embodiment will be mainly described.

In the present embodiment, it is assumed that each of the ozone storage containers 2 is provided with the temperature measuring device 22 described in the first embodiment. In the present embodiment, the ozone amount calculation device 1b performs the same operation as that of the first embodiment, monitors the state of the ozone storage container 2, and outputs an alarm when it is determined that the state should be warned to the user. ..

In the present embodiment, the measurement information acquisition unit 11 performs the same operation as that of the first embodiment, and outputs the temperature measurement information to the monitoring unit 18. The monitoring unit 18 monitors the temperature of the ozone storage container 2 using the temperature measurement information, and generates and generates an alarm warning that the temperature is high when the temperature indicated by the temperature measurement information is equal to or higher than the temperature threshold value. The alarm is output to at least one of the output unit 14 and the alarm device 52. The monitoring unit 18 may transmit a signal instructing the alarm output to the alarm device 52 via the output unit 14. Further, although not shown, the monitoring unit 18 may transmit an alarm to the display device 21 via the output unit 14, and the display device 21 may display the alarm. The temperature threshold is calculated from the relationship between the temperature and the half-life of ozone, and is set to a temperature such that the half-life is equal to or higher than a certain value.

The alarm device 52 may be provided in the ozone storage container 2, or may be provided in a management room, a living room, or the like in the ozone utilization facility. The alarm device 52 warns the user that the temperature of the ozone storage container 2 is high, for example, by outputting at least one of sound, light, and vibration as an alarm. When the alarm device 52 outputs a sound, the alarm device 52 may notify the user by voice that the temperature of the ozone storage container 2 is high, or may emit a predetermined alarm sound. When the alarm device 52 outputs light or vibration as an alarm, the alarm device 52 emits light or vibrates in a predetermined pattern, for example. When the alarm is transmitted to the user terminal 4, the monitoring unit 18 may notify the user by voice that the temperature of the ozone storage container 2 is high, or the user terminal 4 may notify the user of a predetermined alarm. It may make a sound or vibrate in a predetermined pattern. Further, the user terminal 4 may indicate that the temperature of the ozone storage container 2 is high. The output unit 14 outputs an alarm to at least one of the alarm device 52 and the user terminal 4.

The higher the temperature, the faster the autolysis of ozone progresses, so it is preferable to store it at a low temperature. FIG. 15 is a diagram showing an example of storage of the ozone storage container 2 of the present embodiment. As shown in FIG. 15, the ozone storage container 2 is stored in the ozone storage chamber 5. By keeping the ozone storage chamber 5 at a low temperature, it is possible to suppress autolysis of the ozone storage container 2 in the ozone storage chamber 5. On the other hand, the ozone storage container 2 is taken out from the ozone storage container 5 such that the ozone storage container 2 is taken out from the ozone storage room 5 or accidentally moved from the ozone storage room 5 to another place. And the ozone storage container 2 cannot be maintained at a low temperature.

In the example shown in FIG. 15, one of the ozone storage containers 2 stored in the ozone storage chamber 5 has moved out of the ozone storage chamber 5. If the ozone storage container 2 is returned to the ozone storage chamber 5 in a short time, the temperature rise can be suppressed, but if the ozone storage container 2 is left in a high temperature environment for a long time, the temperature of the ozone storage container 2 rises. In such a case, the ozone amount calculation device 1b monitors the temperature of the ozone storage container 2 using the temperature measurement information received from the temperature measurement device 22 of the ozone storage container 2, and the temperature becomes equal to or higher than the temperature threshold value. In this case, the above-mentioned alarm is output to at least one of the alarm device 52 and the user terminal 4 via the output unit 14. As a result, the user can be alerted, and the user can quickly return the ozone storage container 2 to the ozone storage chamber 5. As described above, the ozone amount calculation device 1b of the present embodiment can support the appropriate management of the ozone storage container 2.

In the above-described example, the monitoring unit 18 issues an alarm based on the temperature, but when the ozone storage container 2 is away from the specified location for a certain period of time (time threshold value) or longer. May issue an alarm. As a method of detecting whether or not the ozone storage container 2 is separated from the specified place, for example, an installation table for installing the ozone storage container 2 is provided, and it is detected that the ozone storage container 2 is separated from the installation table. A method can be used in which a sensor is provided and the ozone amount calculation device 1b receives a signal from the sensor to detect whether or not the ozone storage container 2 has moved away from a predetermined place, but the present invention is not limited thereto.

FIG. 16 is a diagram showing an example of the installation table and the ozone storage container 2 of the present embodiment. In the example shown in FIG. 16, the sensor 25 is provided in the ozone storage container 2, and the ozone storage container 2 is placed and stored on the installation table 200. In this example, the defined location is on the pedestal 200. The sensor 25 detects, for example, whether or not it is in contact with the installation table 200, that is, whether or not the ozone storage container 2 is present at a predetermined location by using light, ultrasonic waves, magnetic waves, electric signals, or the like. .. The sensor 25 detects whether or not the ozone storage container 2 is in contact with the installation table 200, and transmits the detection result as movement detection information to the ozone amount calculation device 1b.

As a method of detecting whether or not the ozone storage container 2 is separated from a predetermined place, for example, a sensor 25 which is a position detection device capable of acquiring the position information of the ozone storage container 2 and transmitting the acquired position information is provided. , The ozone amount calculation device 1b may be a method of receiving the position information and determining whether the ozone storage container 2 is away from the specified place. The method for detecting whether or not the ozone storage container 2 has moved away from the specified location is not limited to the above-mentioned example.

When the measurement information acquisition unit 11 of the ozone amount calculation device 1b acquires the movement detection information from the sensor 25, the movement detection information is output to the monitoring unit 18. The monitoring unit 18 carries out the monitoring process described below using the movement detection information.

FIG. 17 is a flowchart showing an example of monitoring processing in the monitoring unit 18 of the present embodiment. The monitoring unit 18 acquires the movement detection information (step S11). Specifically, as described above, the monitoring unit 18 acquires movement detection information from the sensor 25 via the measurement information acquisition unit 11.

The monitoring unit 18 determines whether or not the ozone storage container 2 is present at a predetermined position (step S12). In the monitoring unit 18, for example, when the movement detection information is information indicating whether or not the ozone storage container 2 is in contact with the installation table 200, the movement detection information is the ozone storage container 2 with the installation table 200. When it indicates that they are in contact with each other, it is determined that the ozone storage container 2 is present at a predetermined position.

When the ozone storage container 2 is present at a predetermined position (step S12 Yes), the process from step S11 is performed again. When the ozone storage container 2 does not exist at the specified position (step S12 No), the monitoring unit 18 determines whether or not the measurement of the elapsed time has been started (step S13). The elapsed time is the elapsed time from the time when the ozone storage container 2 leaves the specified position.

If the elapsed time measurement has not been started (step S13 No), the monitoring unit 18 starts measuring the elapsed time (step S14) and repeats the process from step S11. When the measurement of the elapsed time has been started (step S13 Yes), the monitoring unit 18 determines whether or not the elapsed time is equal to or longer than a certain time (step S15).

When the elapsed time is a certain time or more (step S15 Yes), the monitoring unit 18 outputs an alarm (step S16) and repeats the processing from step S11. In step S16, in detail, the monitoring unit 18 generates an alarm warning that the ozone storage container 2 has been away from the specified place for a certain period of time or longer, and issues the alarm to the user terminal 4 via the output unit 14. Send to. Further, the monitoring unit 18 transmits a signal instructing the output of the alarm to the alarm device 52 via the output unit 14.

If the elapsed time is not longer than a certain time (step S15 No), the monitoring unit 18 repeats the process from step S11. If Yes is determined in step S12 after the start of the elapsed time measurement, the elapsed time is reset to 0 and the elapsed time measurement is stopped.

As described above, the monitoring unit 18 uses the movement detection information indicating whether or not the ozone storage container 2 is present in the specified place to determine whether or not the ozone storage container 2 is present in the specified place. Judging, if the time when the ozone storage container 2 does not exist in the specified place continues for more than the time threshold value, an alarm is generated. The above-mentioned fixed time, that is, the time threshold value is determined, for example, according to the amount of self-decomposition of ozone at a temperature corresponding to normal temperature. , It is determined as the time from the amount of ozone at the start of movement to the self-decomposition of ozone in a specified ratio or amount. That is, the time threshold is calculated based on the amount of ozone self-decomposing.

The ozone amount calculation device 1b may perform both the monitoring process of outputting an alarm when the above-mentioned temperature exceeds the temperature threshold value and the monitoring process shown in FIG. 17, or perform either of them. You may. Further, the monitoring unit 18 of the ozone amount calculation device 1b may output an alarm when the temperature becomes equal to or higher than the temperature threshold value for a certain period of time or longer.

Further, in the example shown in FIG. 14, the ozone amount calculation device 1b performs the same operation as that of the first embodiment and also performs the processing by the monitoring unit 18 described above, but is not limited to this, and is not limited to the first embodiment. The processing by the monitoring unit 18 described above may be performed without performing the same operation. That is, the ozone amount calculation device 1b does not have to include the autolysis amount calculation unit 12, the residual ozone amount calculation unit 13, the facility information storage unit 15, and the facility information acquisition unit 16.

The ozone amount calculation device 1b of the present embodiment can also be realized by, for example, the computer system illustrated in FIG. 5, similarly to the ozone amount calculation device 1 of the first embodiment. Further, the ozone storage container 2 may be provided with the ozone amount calculation device 1b as in the example shown in FIG. For example, the ozone storage container 2 may include an ozone amount calculation device 1b and an alarm device 52. In this case, the ozone storage container 2 uses the movement detection information indicating whether or not the ozone storage container 2 is present in the specified place, and the ozone storage time is such that the ozone storage container 2 is not present in the specified place. If it continues for more than the time threshold calculated based on the amount of self-decomposition of ozone according to the storage environment of the container 2, an alarm is output.

As described above, the ozone amount calculation device 1b of the present embodiment performs at least one of the monitoring process by temperature and the monitoring process by the time when the ozone storage container 2 is away from the specified place. When it is judged that it is necessary to take measures to suppress self-decomposition by the monitoring process, an alarm is output.
