Description

An embodiment of the present invention relates to a gas container management device and a gas container management program.

Gases that are generally distributed in the market, such as propane gas, acetylene gas, oxygen gas, and nitrogen gas, are first filled into gas containers at a filling plant, and then transported to affiliated sales outlets by collection and delivery staff. Then, it is delivered from each store to the final customer (user) such as a home or office. Also, the empty gas containers collected by each store or delivery company are collected by the filling factory or by the collection and delivery vehicle of each store and transported to the filling factory. Then, it is refilled with gas and sent to each store or user again.

In the buying and selling of such various gases, the object of the buying and selling is the filled gas, not basically the gas container containing the gas. And, as is clear from the distribution of the gas described above, the gas container is circulated and used repeatedly among filling factories, dealers, and users. Therefore, from the aspect of safety management regarding the gas container itself, it is necessary to reliably perform registration of the owner of the gas container, inspection based on the material of the gas container, and disposal in some cases.

On the other hand, it is important for filling factories, dealers, and users in which gas containers are circulated to know the exact location of the gas container at all times. In particular, in the case of storing high-pressure gas, if the storage amount exceeds a certain amount stipulated by law, the gas storage permission category will change, so a new storage permission or notification will be required.

Therefore, regarding the management of gas cylinders, the relationship between the user of the gas cylinder management server, the gas cylinder owner, and the actual manager of the gas cylinder is defined together with the gas cylinder management information specified by the cylinder symbol/number as the administrator attribute. A method of managing by a container management server and displaying its attributes has been proposed.

That is, by displaying the manager attribute of each gas container from the viewpoint of the user of the gas container management server, the actual manager can be clarified even if the owner and manager of the gas container are different. can be done.

Patent No. 5409943

Certainly information about who is using the gas container is important. For example, the place where the gas container is installed is the place where the person who actually uses the gas exists, and is often different from the person who pays for the amount of gas used. In addition, gas containers are often large and heavy, and when it is necessary to collect and deliver to a user who is far away from the store, there may be circumstances such as requesting a store near the user to collect and deliver.

On the other hand, when managing gas cylinders, it is not only the relationship between those who handle the gas cylinders in their respective positions, such as the person who uses the gas and the person who bears the costs, but also the information on the gas cylinders themselves, as mentioned above. There is a wide variety of information that is essential and required from a security point of view related to gas containers.

In other words, the object of sale is a gas that requires careful handling, and for that reason, there are regulations and restrictions from various perspectives regarding its safety, and as mentioned above, there are people who handle gas containers in various positions. Considering that the locations of gas containers are frequently changed, it is very important to manage gas containers, especially to manage and update safety information, while complying with laws and regulations.

On the other hand, if we are always aware of the need to manage and update a wide range of safety information, and we also have to manage gas cylinders, we will not only be unable to manage and update reliable safety information, but we will also be unable to manage gas cylinders. It may also be difficult to achieve compatibility with management.

The present invention uses information necessary for managing gas cylinders, and in daily processing, it is possible to execute reliable management of safety information without being particularly conscious of it, and to reflect the safety information in the management of gas cylinders. An object of the present invention is to provide a gas container management device and a gas container management program.

It has a security information acquisition unit that acquires security information related to the content of the process from the storage unit, and in the storage unit, there are multiple people related to the gas cylinder, and when multiple roles are recognized for each position. , the information of the persons concerned with these gas containers is stored in a hierarchically divided manner for each role in the standpoint of the person concerned with one gas container.

The control unit further includes a notification unit that notifies the manager of the gas container management device based on the acquired security information.

In the gas container management device according to the embodiment of the present invention, the persons related to the gas container are displayed on the display unit in a hierarchical manner as they are stored, and the persons related to the gas container are displayed in each hierarchy. It is displayed by changing the display mode of the person who does it. Also, the hierarchy displayed on the display unit is divided into three.

In addition, the control unit refers to the security information for words and phrases used in the gas container management process according to the container ownership classification that classifies the owner of the gas container of the person related to the gas container to which the gas container is delivered. Convert automatically.

Further, the gas container management program according to the embodiment of the present invention comprises the step of storing safety information related to the gas container in the gas container management device, A step of acquiring and displaying related safety information from the storage unit for each management process; The information of the person concerned with one gas container is divided into layers for each role in the position of the person related to one gas container, and the information of the person related to the gas container, the gas container to which the gas container is delivered. and a step of obtaining and displaying the security information of the gas container linked to the information of the person related to the person concerned .

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the embodiment described below shows an example of the present invention. In addition, various modifications or improvements can be added to the present embodiment, and the embodiments to which such modifications or improvements are added can also be included in the present invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the scope of the invention described in the claims and its equivalents.

[Configuration of gas container management system]
FIG. 1 is a configuration diagram showing the overall configuration of a gas container management system S including a gas container management device 1 according to an embodiment of the present invention. The gas container management system S is configured, for example, by connecting each device constituting the gas container management system S to an information communication network N such as the Internet.

As described above, the gas container management system S connected to the information communication network N in FIG. 1 is configured by being used at a store 2 , a filling plant 3 and a user 4 . Therefore, FIG. 1 shows a state in which the gas container management device 1 is installed at each of the store 2, the filling factory 3, and the user 4. As shown in FIG.

The store 2 is a person who sells gas to a user 4 who is a gas user. The store 2 delivers the gas container filled with the necessary gas to the user 4 based on the user's request. Also, after the user 4 has used up the gas, the empty gas container is recovered and the gas container is refilled with gas.

The filling factory 3 is a factory that fills gas containers with gas, and corresponds to a so-called manufacturer. The store 2 has the gas container filled with the gas in the filling factory 3 and keeps it as an inventory in order to respond to the order from the user. Then, according to the order from the user 4, the gas container filled with the corresponding gas is delivered to the user 4. Alternatively, if the store 2 has the same function as the filling factory 3 , the store 2 fills the gas and delivers it to the user 4 .

The user 4 is a person who is related to the gas container and who uses the gas in the gas container delivered from the store 2 like the store 2 and the filling factory 3 . The user 4 can be an individual, various factories, or a hospital.

Here, for example, when the user 4 is an individual, the person who uses the gas and the person who bears the costs generated by the use of the gas are often the same. On the other hand, in the case of a company, the person who actually uses gas and the person who bears the cost may be different, for example, the former is a factory and the latter is the head office.

In this way, from the viewpoint of cost sharing for gas use, the gas user and the cost bearer are not necessarily the same. On the other hand, security information must be grasped for each location where gas containers actually exist.

Therefore, in the following embodiments of the present invention, these are collectively and broadly referred to as "users" as appropriate. On the other hand, in cases such as confirmation of security information in conjunction with gas container management processing, there are cases where persons involved in gas containers included in the concept of the user are explained in detail in a case-by-case basis.

As described above, the gas container circulates and moves among the store 2, the filling factory 3, and the user 4 shown in FIG. Therefore, the store 2, the filling factory 3, and the user 4 need to use the gas container management device 1 from their respective standpoints to manage gas containers and safety information as necessary. Therefore, as shown in FIG. 1, the gas container management device 1 can be installed in each store 2 or the like.

However, the following description is based on the premise that the gas container management device 1 installed at the store 2 is used. Various types of information including gas container management information and security information are managed by the gas container management device 1. These information are stored in a cloud server (not shown) placed on the information communication network N, for example. It may be stored.

In addition to the gas container management device 1 installed in the store 2 or the like, the gas container management system S shown in FIG. ) are also connected via the information communication network N. The portable information terminal 5 is used, for example, by a collection and delivery staff when collecting and delivering gas containers to various places such as the user 4 described above.

Such a portable information terminal 5 is, for example, a device used for reading a bar code or the like provided on a gas container to specify the gas container and manage the gas container at the place of work. Therefore, for example, even if all the functions of the gas container management device 1 described below are executable, or even if only selected functions among the functions of the gas container management device 1 are executable, good.

Here, FIG. 1 shows three portable information terminals 5: portable information terminals 5A and 5B, which are so-called handy terminals, and portable information terminal 5C having the form of a smart phone, for example. ing. However, in addition to these forms, the portable information terminal 5 may be any form such as a tablet or various devices included in a PDA (Personal Digital Assistant) as long as it is a device capable of executing the functions described above. It's okay to be there.

The information communication network N connects the gas container management devices 1 installed at various locations of the store 2, the filling factory 3, and the user 4, and the portable information terminals 5, respectively. By being connected to the information communication network N, these devices are enabled to exchange, for example, security information about the gas container and information about the persons involved in the gas container. Examples of the information communication network N include a network such as the Internet and a LAN (Local Area Network).

In FIG. 1, the information communication network N is connected to the store 2, the filling factory 3, and the gas container management device 1 installed at each location of the user 4, and the portable information terminal 5. are shown, devices other than these devices may be connected.

Further, in the gas container management system S shown in FIG. 1, each of the store 2, the filling factory 3, and the user 4 is shown connected to the information communication network N by solid lines. This indicates that these devices and locations are connected to the information communication network N by wire.

However, each of these units may be configured to be wirelessly connected to the information communication network N, respectively. On the other hand, the portable information terminal 5 is shown to be wirelessly connected to the information communication network N. FIG.

[Internal configuration of gas container management device]
Next, the gas container management device 1 will be described in further detail below. FIG. 2 is a block diagram showing the internal configuration of the gas container management device 1 according to the embodiment of the invention.

The gas container management device 1 has a configuration in which a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, and an input/output interface 14 are connected via a bus B. there is Further, the input/output interface 14 is connected with an input unit 15 used by a person who operates the gas container management device 1, a display unit 16, a communication control unit 17, a storage unit 18, and a control unit 19. .

The CPU 11 reads and executes a boot program for activating the gas container management device 1 from the ROM 12 based on the input signal from the input section 15 and reads various operating systems stored in the storage section 18 . The CPU 11 also manages gas containers and security information based on input signals from other external devices (not shown in FIG. 2) via the input unit 15 and the input/output interface 14. Also good.

Further, the CPU 11 reads programs and data stored in the RAM 13, the storage unit 18, etc. and loads them into the RAM 13, and also manages the gas container management device 1 itself and controls the gas container based on the commands of the programs read out from the RAM 13. It is a processing device that realizes a series of processing such as calculation and processing of data required when performing the management processing of .

The input unit 15 is configured by an input device such as a keyboard or a touch panel through which the operator of the gas container management device 1 inputs various operations. An input signal is created based on the operator's operation via the input unit 15 and transmitted to the CPU 11 via the bus B. FIG. In addition, devices provided in the gas container management device 1, such as a microphone and a camera, or various devices connectable to the gas container management device 1 can also be cited as a type of the input unit 15.

The display unit 16 is, for example, a monitor. This display unit receives an output signal from the CPU 11 via the bus B, and displays, for example, information necessary for managing the gas container, user information, or the processing result of the CPU. The display unit 16 may also include a liquid crystal display, an organic EL display, or a device that notifies the operator by voice.

The communication control unit 17 is means such as a LAN card and a modem, and is a means for connecting the gas container management device 1 to an information communication network N such as the Internet or LAN. Data transmitted/received to/from the information communication network N via the communication control unit 17 is transmitted/received to/from the CPU 11 via the input/output interface 14 and the bus B as an input signal or an output signal.

The storage unit 18 is composed of a semiconductor or a magnetic disk, and stores programs and data, such as a gas container management program, which are executed by the CPU 11, for example, for performing gas container management processing, safety information notification, and the like. It is

Also, here, it is assumed that the storage unit 18 is provided inside the gas container management device 1, but for example, an external storage medium such as an external hard disk or flash memory can be used. Alternatively, it is possible to use a server connected to the information communication network N as the storage unit.

FIG. 3 is an explanatory diagram showing an example of the configuration of information stored in the gas container management device 1 according to the embodiment of the present invention. That is, the storage unit 18 stores security management information 181, gas container management information 182, sales management information 183, dealer information 184, filling factory information 185, and user information 186, for example.

It should be noted that FIG. 3 shows that only information necessary for explanation in the embodiment of the present invention is stored. Therefore, the contents of the information stored in the storage unit 18 may include not only the various information shown in FIG. 3, but also various operating systems such as those described above.

The security management information 181 is information relating to the security of gas containers. Security management information (hereinafter referred to as “security information” as appropriate) covers a wide range of fields, and includes, for example, inspection and disposal management of gas containers, and information such as the amount of gas stored in gas containers. In addition, the security management information 181 also includes information on public notices and the like provided when notifying the user 4 of the security information.

In other words, when managing gas cylinders, security information such as the inspection period, disposal period, and gas filling amount must be grasped for each location where the gas is actually used, that is, for each final destination of the gas cylinder. need to keep This is because the gas container exists at the final destination, and managing security information at this location is the most appropriate and contributes to safety.

Therefore, gas container management processing and sales management processing at the final destination are performed, and when these processings are executed, mainly security management information 181 and gas container management information 182 stored in the storage unit 18 are processed. , and sales management information 183 are linked with each other to execute security management.

Here, "security information" is a general term for various information required to ensure the safety of gas containers. In other words, when considering the safety of gas containers, for example, information about the gas container itself, such as the material of the gas container, the inspection period, and the disposal period, as well as the location where the gas container is stored. User information related to the gas container, such as what kind of user is the user, and what is the purpose of use, can also be mentioned.

In this way, security information is stored in various places as information in a wide variety of ways. Therefore, it is difficult for the operator of the gas container management device 1 to manage such security information by appropriately updating it. Therefore, in the gas container management device 1 according to the embodiment of the present invention, during the gas container management process or the sales management process, the safety information related to the execution of these processes is appropriately provided to the operator. The operator can certainly confirm the security information and comply with laws and regulations without having to access the security information and confirm the contents of the information each time.

Therefore, the main security information will be described below. The security information that can be handled by the gas container management device 1 is not limited to the security information described below.

First, the safety information regarding the gas container will be explained. FIG. 4 is an explanatory diagram showing an aspect of the gas container 6 to be managed in the embodiment of the present invention. A re-inspection date 61, a container owner number 62, a container symbol/container number 63, and a filling gas name 64 are stamped on the outer surface of the gas container 6 according to the embodiment of the present invention. The filling gas name 64 is a stamp for indicating the type of gas filled in the gas container 6 .

Note that the term "stamping" here includes not only the case where the surface of the gas container 6 is actually carved and marked, but also the case where information is indicated by a sticker or the like. Also good.

The re-inspection date 61 is the date when the gas container 6 was inspected. As will be described later, the gas container 6 needs to be inspected, for example, at certain intervals, and it may not be allowed to be used beyond the number of years set as the useful life.

Therefore, a re-inspection date 61 is stamped on the outer surface of the gas container 6.例文帳に追加In addition, a symbol number is obtained from a separately attached par-code, and the gas container management device 1 is accessed to confirm whether or not the inspection is necessary, and to inform the expiry of the inspection period. Of course, various types of information related to the inspection, including the re-inspection date, are stored in the security management information 181 and the gas container management information 182 .

The container owner number 62 is a number assigned to the person who owns the gas container 6 . In the gas container 6 shown in FIG. 4, it is a four-digit symbol/number. As for the container owner number 62, for example, there is a number assigned by an organization such as the High Pressure Gas Safety Institute, and the number assigned by the organization is stamped. In addition, when the owner of the gas container 6 is changed due to trading or the like, a new stamp is required.

The container symbol/container number 63 is a symbol/number as identification information for identifying each gas container 6 . The reason why the container symbol/container number 63 is stamped on the gas container 6 is that various information specific to the gas container 6, such as inspection information and gas type information regarding the gas container 6 can be confirmed. is.

From this point of view, in the past, symbols and numbers were given without duplication, but since the self-safety of gas cylinders has become a situation, there are multiple identical symbols and numbers. Therefore, in the gas container management device 1 according to the embodiment of the present invention, the container symbol/container number 63 is changed by increasing the number of digits of the symbol/number for distinguishing the gas container 6 or by adding the symbol/number identification. It is possible to manage without duplication.

Therefore, for example, an operator of the gas container management device 1 or a delivery person using the portable information terminal 5 (hereafter collectively referred to as "operator, etc." as necessary) confirms the state of the gas container 6. In order to access the information of the gas container 6, the necessary information can be obtained by inputting or reading the container symbol/container number 63. FIG.

At the same time, by associating other information such as the gas type, container manager, and container owner, it is possible to make a determination simply by inputting or reading the container symbol/container number 63 stamped on the gas container 6 as before. is made possible.

Specifically, for example, when the container symbol/container number 63 is read by the collection and delivery staff using the portable information terminal 5, if a plurality of identical container symbols/container numbers 63 exist, all Information on the container symbol/container number 63 is listed and displayed. Therefore, the collection and delivery staff can specify the gas container 6 by selecting the corresponding gas container 6 from among the container symbols/container numbers 63 listed on the list, for example, based on information such as the type of gas.

A recording medium 65 for identifying the gas container 6 is attached to the gas container 6 . The recording medium 65 contains various information about the gas container 6 , and the information on the gas container 6 can be accessed by reading the information using the portable information terminal 5 , for example. Further, after processing the information based on the information, the information can be transmitted to the gas container management device 1 .

Here, in the gas container 6 shown in FIG. 4, a bar code is used as the recording medium 65, but any recording medium capable of recording information on the gas container 6, such as a QR code (registered trademark), may be used. ), RFID, etc. can also be adopted.

As described above, each gas container is finally given a unique container symbol/container number. The container symbol/container number is necessary for managing individual gas containers. In this way, gas containers are managed one by one, but there are cases where a plurality of these gas containers are grouped together as one unit and the set is distributed as one mass.

This is used when the user 4 uses, for example, one or more bottles of the same gas type, and is called a "curdle". For this reason, gas containers grouped together as a cardle are filled, delivered, and collected in units of this unit.

As described above, each gas container is assigned a container symbol/container number and managed. As a matter of course, a container symbol/container number is assigned to each bottle.

However, if they are grouped together as a cardle, they move as a group as described above. In addition, if the gas cylinders in such a state are managed one by one each time, the processing will be troublesome. Therefore, in addition to managing each gas container, each cardle is given a container symbol/container number and managed on a cardle basis.

Even when management is performed on a cardle-by-curdle basis, a container symbol/container number is assigned to each cardle. It becomes clear whether it is a single gas container or a single gas container managed as a cardle, and it is possible to prevent designation errors.

In addition, since it will be managed by cardle unit, while the gas container is incorporated as one that constitutes the cardle, management by the container symbol/container number given to each gas container will rather be managed by the operator. It can be confusing.

Therefore, in the gas container management device 1 according to the embodiment of the present invention, when management is executed in cardle units, the controller 19 controls the container symbol of the cardle regardless of which one of the built-in gas containers is specified. • Automatically converted to a container number.

The container symbol/container number of the cardle and the container symbol/container number assigned to each gas container constituting the cardle are associated with each other. Therefore, the processing performed based on the container symbol/container number of the cardle or the processing performed based on the container symbol/container number assigned to each gas container reflects the contents of each processing.

By carrying out such a process, it is possible to reliably manage each cardle unit or each individual gas container.

Furthermore, for example, when the gas type is acetylene, it is conceivable to collectively manage a plurality of gas containers, which should originally be managed individually, in the same way as the cardle described above.

In the case of gas containers filled with acetylene, if the gas container is obtained in bulk at the time of purchase, one lot number is assigned to these bulks. That is, when the gas container registration process is executed, in addition to registration for each gas container, a lot number is given to the group.

This is a special case for acetylene gas cylinders, and when a pressure test is performed on one of the cylinders in the cluster, it constitutes a cluster containing this one (the same lot number is given), etc. This is in line with the fact that the representative gas container has already been inspected for the gas containers in (1) and that the inspection process is performed. In addition to the one inspected, the same date of inspection is stamped on the outer surface of other gas containers to which the same lot number is assigned.

Since such management is performed, when a new inspection for a representative gas container is completed, that fact is registered as security management information 181 and gas container management information 182, and the outer packaging of the gas container is registered. A new stamp is stamped on the surface (re-engraving). For other gas cylinders having the same lot number, the security management information 181 and the gas cylinder management information 182 need to be updated and the gas cylinders need to be changed.

The security management information 181 and the gas container management information 182 are updated automatically by the controller 19 because the lot number is associated with the container symbol/container number of each gas container. On the other hand, re-engraving requires actual work one by one.

Therefore, it is necessary to manage all the gas cylinders to recycle them, and the notification unit 192 notifies the operator or the like to recycle the gas cylinders. It does not matter which order the security management information 181 and the gas container management information 182 are updated and the revise is performed. If 182 is to be updated, it will not be updated if it is not revised, and the effect of informing the operator or the like will be greater.

In this way, although gas cylinders circulate and move through stores 2 and the like, security management is performed individually at the place where the gas cylinder is finally placed and used, thereby further increasing its effectiveness. be able to. This is because management is performed using the container symbol/container number regardless of whether it is an individual unit or a cardle unit. It is possible to smoothly proceed with the management of personnel, etc. without omission.

Next, the gas container is made of aluminum alloy, steel, FRP, or the like, and since all of them are filled with high-pressure gas, the load on the gas container is large. For this reason, gas cylinders are inspected at regular intervals and their expiration dates are set. These inspection deadlines and usage deadlines are safety information, and deadline management is required.

Regarding the inspection and expiration date (deadline for disposal), some gas containers are set on a yearly basis, such as 3 or 5 years, while others have an irregular deadline set on a yearly basis, such as 2 and a half years. Sometimes there are. Therefore, in the gas container management device 1 according to the embodiment of the present invention, these deadlines are displayed in a unified manner, and displayed in units of months, such as December for one year and 30th for two and a half years. I decided to let

Therefore, when the gas container registration process is performed, it is possible to input the inspection deadline and the expiration date on a monthly basis, and these deadlines set on a monthly basis for each gas container are stored in the gas container management information 182. be. Then, the controller 19 of the gas container management device 1 notifies the operator or the like through the notification unit 192 in accordance with the arrival of various deadlines for each gas container.

In addition, when the gas container is an FRP container, its expiration date must be strictly observed. This is due to the material called FRP, but the expiration date is the disposal date, and use beyond the expiration date is absolutely prohibited. Specifically, when the gas container is an FRP container, it is stipulated that it must be discarded after 15 years from the date of manufacture, and after 15 years, its use such as refilling and movement is completely prohibited. Therefore, the time limit also corresponds to safety information, and is appropriately notified to the operator or the like.

In addition, in notifying the operator of the expiration date, for example, a predetermined period until the expiration date is determined in advance, and when the preset period has passed before the expiration date, the notification is performed. is also possible.

Next, let us consider information corresponding to security information from the viewpoint of a person related to the gas container, not from the viewpoint of the gas container explained so far. As for the gas bottle, any of the persons involved in the gas bottle, such as the store 2, the filling factory 3, and the user 4, can own the gas bottle.

Therefore, who owns the gas container to be protected is important information for proper management. Specifically, for example, the response differs depending on which gas container is in the hands of the person related to the gas container whose inspection deadline is approaching.

Also, in the movement of the gas container circulating among these three parties as described above, even if the movement is the same, the concept differs depending on who owns it. Therefore, it is important for safety to clarify who owns the gas container.

Therefore, in the gas container management device 1 according to the embodiment of the present invention, the gas container owner can be registered as the gas container management information 182 . That is, the operator is urged to input a predetermined classification of the gas container when registering the gas container or the user 4 .

In the gas container management device 1 according to the embodiment of the present invention, for example, if the owner of the gas container is the store 2, it is set to "own company: 0"; 4 can be registered as "user container: 2".

From the point of view of safety management, for example, when various processes associated with the movement of the gas cylinder are executed based on the information of the owner of the gas cylinder when the management process of the gas cylinder or the sales management process is performed. In order for the operator or the like to execute the processing appropriately, the control unit 19 automatically converts the words and phrases, and processes the concept in line with the owner's processing.

That is, for example, taking the case where the gas container is owned by the store 2, delivery to the user 4 is the “shipping” of the gas, and receiving the gas container from the user 4 is the “recovery” of the gas. ”. In other words, from the point of view of the store 2, this is a rental of the gas container to the user 4. Therefore, the store 2 can collect the fee for using the gas container from the user 4 .

Further, for example, when the store 2 requests the filling factory 3 to fill the gas container collected from the user 4, the gas container is owned by the store 2, so the request is "delivered by request". Taking over from the filling plant 3 later corresponds to "receipt of requested amount".

Next, when the gas container is owned by the filling plant 3, that is, the manufacturer, the act of delivering the empty gas container to the filling plant 3 in order for the dealer 2 to request filling of the gas container owned by the filling plant 3. is the “return” of the gas container. On the other hand, taking back the gas container after the gas container is filled with the gas corresponds to, so to speak, "receiving" the product. Therefore, from the point of view of the store 2, the relationship between the two is "receiving" and "returning".

Conversely, if the gas container is owned by the filling factory 3, the filling factory 3 receives the filling request from the dealer 2 and receives the gas container as "recovery", and the gas container is shipped to the dealer 2 after filling. What you do is "shipment".

Finally, when the user 4 owns the gas container, in order to fill the gas container with gas, the gas container is moved to the store 2 or to the filling factory 3 via the store 2 and delivered again. This corresponds to "recovery" in the above example. However, since the moving gas container is owned by the user 4, it corresponds to "filling storage" from the point of view of the store 2. And, delivering the gas container filled with gas to the user 4 is "shipping (shipment)".

In this way, when the gas container moves between two parties, there are various concepts other than simply "delivery" and "recovery". Therefore, by automatically converting the expression according to the ownership category registered in the gas container management device 1 so that the expression is more realistic, the operator can perform the processing more intuitively without being confused. I am making it possible.

Next, let us consider security information from the viewpoint of the type of gas that is filled in the gas container and used. Since the gas filled in the gas container is generally filled under high pressure, it is dangerous, for example, if the pressure is suddenly released. In addition, the amount of gas to be stored is strictly regulated for each type of gas, because the gas itself is also flammable.

Specifically, gas species are divided into two types: first-class gases containing inert gases such as helium and neon and air, and second-class gases containing gases other than the first-class gases. Depending on the type of gas to be stored, it is divided into first-class storage and second-class storage, and the amount of storage permitted in each storage is determined.

As described above, security information needs to be managed based on the situation at the place where the gas cylinder is actually stored. Therefore, the storable amount differs for each store 2 , filling factory 3 , or user 4 . Therefore, it is necessary to grasp the amount of gas that can be stored at each location, and to perform safety management while taking into consideration the increase or decrease in the amount of storage due to the movement of the gas container.

Therefore, in the security information acquisition unit 191 of the control unit 19, for example, when information on order processing or sales processing is registered as the sales management information 183, which user 4 has received the order or the like, and how To obtain information on how much quantity of various gas types has been ordered.

Then, based on the information about the storage amount of the user 4, it is determined whether or not the ordered gas is within the range of the storage amount of the user 4 when the ordered gas is delivered. As a result, when the storage amount is exceeded, for example, it is confirmed whether or not it is possible to ship in anticipation of a decrease in the storage amount of the user 4 by recovering the gas container at hand of the user 4 . , etc. are performed.

In addition, Article 9-3 of the Fire Service Law stipulates the notification of storage and handling of ammonia, acetylene gas, etc. Therefore, when storing such types of gas, it is necessary to notify the local fire chief, etc., but whether or not the storage amount is permitted differs depending on the municipality where the storage is located.

Therefore, in the gas container management device 1 according to the embodiment of the present invention, as one of the gas container management information 182 or the sales management information 183, the location where the gas container is stored and the address of the person who manages the gas container are registered. It is possible to

And once a storage location is registered, what gas types are stored in the same storage location, for example in terms of gas containers, and how much, and if further storage is required compared to the amount of storage permitted at that location? It is possible to inform the operator whether or not it is possible, that is, whether or not order reception processing can be executed, for example.

In this way, the storage amount associated with information such as gas type and storage location can also be regarded as one of security information, and it is important to provide security information to operators and the like from this point of view.

In addition, in calculating the amount of storage, it is necessary to grasp what kind of gas is stored and how much. However, depending on the type of gas, for example, how to express the capacity in buying and selling varies.

That is, industry convention is to use four types of transaction units: "book", "m ³ ", "Kg", and "L". Therefore, the transaction unit used is often different for each gas type or for each delivery partner. Therefore, for example, conversion information for converting each transaction unit is stored as one of the sales management information 183 .

For example, when the security information acquisition unit 191 acquires security information about the amount of storage, one of the transaction units is selected for the capacity of each gas container, and for gas types that are traded in different transaction units, the conversion described above is performed. Use the information to unify the transaction unit and aggregate the storage amount. Then, it is determined whether or not the accumulated storage amount is equal to or less than the storage amount allowed by the user 4 .

Next, for example, the gas ordered by the user 4 is filled in a gas container and delivered. At that time, in many cases, from the viewpoint of delivery efficiency, gas containers of various types of gas delivered to various users 4 are loaded on the delivery truck. However, there are gas types that cannot be loaded together on one truck and are prohibited from being mixed. For example, a chlorine gas container and a hydrogen gas container cannot be mixed.

Therefore, in the gas container management device 1 according to the embodiment of the present invention, for example, when creating a gas container delivery instruction accompanying order processing, which is one of the sales management information 183, it is possible to load prohibited gas containers on the same delivery truck. It is confirmed that it will not be done, and the above delivery instruction is created.

Specifically, for example, the security information acquisition unit 191 accesses the sales management information 183 and, based on the contents of the order placed by the user 4, determines that a single truck is loaded with gas containers of gas types that are prohibited from being mixed. It is determined whether or not

Then, if there is a possibility that a gas of a gas type prohibited from being mixed-loaded may be mixed-loaded, for example, a warning to that effect is notified to the operator or the like via the notification unit 192, and the delivery is performed. A change is made to the track used for

By executing such processing and providing the safety information in advance to the operator or the like, it is possible to avoid the occurrence of a dangerous state due to mixed loading. It also leads to being able to formulate a better delivery plan.

Next, depending on the type of gas, it may be necessary to notify the user 4 of the information depending on the application. That is, for example, when a user 4 handles a type of gas for the first time, it is necessary for the store 2 to explain to the user 4 the properties of the type of gas, how to handle it, points to be careful of, and the like. Therefore, the store 2 provides an explanation in writing, and this document is called a notice. In addition, there are cases where it is necessary to periodically issue a notice to the user 4 .

Therefore, as one of the security information that constitutes the security management information 181, the time limit for notification is managed. As described above, the time limit is set and managed for each gas type, such as when periodic announcements are made and when there is a gas type to be handled for the first time.

Moreover, even if the gas type is the same, depending on the intended use at the final destination, there may be cases where the presence or absence of well-known information differs. For example, when the gas type is "oxygen", when it is used for "welding/thermal cutting", when it is used for "medical use", or when it is used for "breathing" such as scuba diving, etc. , The same oxygen has various uses, and it is conceivable that the content and period of publicity will differ for each use. Therefore, in the gas container management information 182, not only the type of gas but also the purpose of use is registered, and whether or not the gas is known, the period, the method, etc. are set according to the purpose of use.

During the gas container management process, for example, it is conceivable that an order for a gas type that the user 4 has never dealt with may be received from the user 4 . In such a case, the safety information acquisition unit 191 of the control unit 19 extracts the safety information related to publicity from the safety management information 181, and the reporting unit 192 displays the information related to publicity on the display unit 16, so that gas container management can be performed. The operator of the device 1 is notified.

The gas container management information 182 is information required when managing gas containers for each gas container. Regarding the process of moving the gas container between stores 2, for example, there are collection data (empty bottle data) at the time of performing the processing of filling the gas container with gas and collecting the gas container.

In addition, as information for master management of gas containers, for example, as described above, container manager information, container ownership category information, gas (commodity) information, information related to the storage amount of gas containers, or information attached to containers information such as symbols and numbers that are present.

In addition, gas containers are manufactured from various materials, and there is also a difference between domestically manufactured gas containers and foreignly manufactured gas containers. For this reason, the timing of inspection and the timing of disposal are determined for each gas container. In particular, information about various periods, such as inspection time and disposal time, is also stored due to the above-mentioned restrictions, for example, when the gas container is made of FRP.

Furthermore, due to the revision and abolishment of laws and regulations, inspection cycles and inspection organizations may be changed. Since the applicable laws and regulations differ depending on the date of manufacture of each gas container, the relationship between the period stipulated by the relevant laws and which laws and regulations apply to which gas container is also stored.

The sales management information 183 stores information used when the store 2 or the like executes processing for selling gas, which is a product, to the user 4 . For example, since the order processing uses the information of the contents of the order from the user 4 (for example, gas type, desired amount, etc.), this information is stored.

As the master management information of the sales management information 183, for example, the same information as the gas container management information 182, such as container manager information and container ownership classification information, is stored. On the other hand, information different from the gas container management information 182 may include, for example, contract information, public information, and information on SDS (Safety Data Sheet).

Here, the SDS is a document describing the description of the product, notice of safety, and measures to be taken in the event of an accident, and is delivered from the store 2 to the user 4. In other words, it is necessary to explain the nature of the gas, how to handle it, precautions, etc. for the kind of gas that the user 4 handles for the first time.

Therefore, it is necessary for the well-known processing to be notified from the store 2 to the user 4 based on the well-known information. A letter is issued.

As described above, the safety management information 181, the gas container management information 182, and the sales management information 183 store various information. Therefore, when an operator or the like uses the gas container management information 182 and the sales management information 183 to execute various processes, the control unit 19 acquires the security management information 181 and the gas container management information through the security information acquisition unit 191 . Necessary information is extracted from the information 182 and the sales management information 183 . Then, the safety information obtained from the acquired various information is notified from the notification unit 192 via the display unit 16 to the operator of the gas container management device 1 and the collection and delivery staff using the portable information terminal 5. conduct.

That is, the security information acquisition unit 191 links various information stored in the security management information 181, the gas container management information 182, and the sales management information 183 with each other to provide necessary security information to the operator. It provides.

Specifically, for example, an example will be given of a storage amount that indicates the amount of gas in a gas container that is stored at hand by the user 4 . For example, the store 2 delivers a gas container to the user 4 .

That is, when the operator executes the sales process, he/she refers to the shipping data stored in the sales management information 183 . At that time, since there is naturally information about what kind of gas and how much was sold to the user 4, the security information acquiring unit 191 uses such processing by the operator as a trigger to obtain gas container management information. Product information and container information stored in 182 are extracted.

At the same time, it also obtains information on all the gas containers that the user 4 has at hand from the sales management information 183 and also obtains information on the amount of storage that can be stored by the user 4 from the gas container management information 182 .

Based on the information thus collected, the security information acquisition unit 191 determines whether or not the storage amount of the user 4 exceeds the allowable storage amount when a new gas container is delivered to the user 4 this time. The display unit 16 is caused to display information such as how much the storage amount including the delivered gas container will be.

In this way, when the operator uses the gas container management device 1 to perform various processes such as sales processing, based on the cooperation of the safety management information 181, the gas container management information 182, and the sales management information 183, , to extract and display security information related to the content of processing. By performing such processing, operators and others can manage safety information reliably without consciously acquiring and confirming safety information each time in their daily processing, and can store safety information on gas cylinders. It can be reflected in management.

The store information 184 is various information such as the name and address of the gas store that uses the gas container management device 1 . In the above case, it is basically difficult to deliver the gas to a distant place, so there are cases where the delivery is entrusted to the store 2 close to the user 4 who uses the gas. The store information 184 is used in such cases.

The filling factory information 185 is information about the filling factory that fills the gas. In addition to the name, address, etc., information such as the type of gas that can be filled is stored.

The user information 186 stores information about so-called users such as those who use gas. Specifically, for example, it is information such as address, delivery destination, type of gas to be handled, and how much can be stored. In addition, based on the set address, information regarding the amount of storage prescribed in Article 9-3 of the Fire Service Law is also stored.

Furthermore, with regard to user information, as described above, it is conceivable that the person who actually uses the gas differs from the person who pays for it. Therefore, when the person who bears the cost and the gas user are different, the information is stored in separate layers. Specifically, in the storage unit 18 according to the embodiment of the present invention, the information is divided into three layers and stored.

In the first layer, users who are business partners are stored. The users stored in the first hierarchy are, for example, billing parties. As described above, taking the case of a company with factories as an example, gas is delivered to each factory, but payment is made to the head office. Stored in hierarchy.

In the second layer, users who are route destinations and management destinations are stored. That is, even if it is said to be delivered to a factory, for example, in the case of a large factory, there may be a plurality of delivery destinations within the factory. In such a case, it is conceivable that gas cylinders to multiple delivery destinations within the factory are collectively managed by, for example, the management department of the factory. Therefore, such management departments are stored in the second hierarchy.

Further, for example, because the delivery destination of the gas cylinder is far away as described above, there may be a case where the delivery destination is located in a place where the delivery cannot be made from the store 2 itself. In such a case, it is conceivable to consign the delivery to the store 2 close to the delivery destination (payment on behalf of the customer). In the second layer, information about the store 2 requesting such a substitute payment is stored.

The third layer stores the final destination, which is the place where the gas cylinder is actually delivered. In the case of the example of the factory described above, the information stored in the third layer includes a plurality of delivery destinations (for example, manufacturing section ◯) in the factory. Also, in the case of substitute payment, information on the delivery destination of the substitute store is stored in the third layer.

Here, the final report destination is the third layer, but not all users 4 are layered in this way. User 4 may be the final destination of the report.

A unique user number is assigned to each user 4. Among the users 4 stored in a hierarchical manner, the users 4 stored in the lower hierarchy are the users 4 stored in the upper hierarchy. has taken over the user number given to

That is, for example, when a user number "010601" is assigned to the first layer, the user number to user 4 stored in the second layer is "01060101", taking over the number of the first layer and It is a number composed by adding a 2-digit number to the end.

Similarly, the third layer inherits the user number "01060101" of the second layer and adds a number to the end, resulting in a user number "0106010101". Then, when the number of users 4 increases in the same layer, for example, it is handled by increasing the number at the end indicating the layer to "0106010102".

In this way, users 4 are hierarchized and stored, and each user 4 in all hierarchies is associated with the given user number. Therefore, for example, even when the user 4, who is stored in the first layer, is billed for the cost of delivery to the final destination, the operator does not have to specify the destination each time if the final destination is specified. Both are automatically specified by the gas container management device 1 . Therefore, it is possible to save the labor of the operator and reduce errors such as input errors.

In addition, when the user 4 is displayed on the display unit 16 as the user 4 is stored in a hierarchical manner, the user 4 is displayed on the display unit in a hierarchically divided display mode as stored. Is displayed. FIG. 5 is an explanatory diagram showing a user's display mode displayed on the display unit 16 in the gas container management device 1 according to the embodiment of the present invention.

In the screen example shown in FIG. 5, search contents and input items are displayed side by side in the upper row. User 4 is displayed below it. In the screen example shown in FIG. 5, there are five items: "delivery partner code", "delivery partner classification", "delivery partner abbreviated name", "delivery partner name" and "delivery partner department name". They are lined up from left to right. Here, of the displayed users 4, "Aki△ Industry Co., Ltd." will be described as an example.

First, for the sake of understanding, the second from the left, "Delivery destination classification," will be explained. In the case where the user who is the delivery destination of the gas cylinder and the user who bears the cost are separated, this delivery destination classification includes the user who is the customer, the user who is the destination and the management destination, and This is a division for distinguishing from the user who is the final destination.

In the case of "Aki△ Industry Co., Ltd.", "0 Customer (business partner)" (1st layer), "1 Recipient 1 (via destination or management)" (2nd layer), "2 Recipient 2 (final destination) )” (3rd layer), and especially for the final destination “2 destination 2”, three are registered. That is, looking at the "delivery destination name", "0 Customer" is "Aki △ Kogyo Co., Ltd." It can be said that there is.

On the other hand, if you look at the "delivery destination name" of "1 Destination 1 (transit destination or management destination)", it is "Aki △ Kogyo Co., Ltd. Tokyo Branch", so the branch of "Aki △ Kogyo Co., Ltd." It can be seen that it is. Further, under this branch office, three of "Ginza Sales Office", "Koto Sales Office", and "Setagaya Sales Office" are registered. The "delivery destination classification" of these three business offices is "2 destination 2", and these three business offices are, so to speak, the final destination.

The display for each of these categories is displayed as displayed in the "delivery partner's abbreviated name" section. In other words, based on the display of "Aki △ Kogyo Co., Ltd." in the "0 Customer" column, the display of "1 Recipient 1" ("Aki △ Kogyo Tokyo") is is displayed shifted by one character.

In addition, each business office corresponding to "2 Addressee 2" is displayed shifted one character further to the right from the display in the column "1 Addressee 1". In other words, it is shifted two characters to the right from the reference "0 customer". The three business offices, which are the final delivery destinations, are displayed at the same position because they all correspond to delivery destinations belonging to the same hierarchy as the third hierarchy.

As shown in the "delivery destination abbreviation", by shifting and displaying the notation for each hierarchy, for example, when the user 4 is stored in a plurality of hierarchies, one hierarchy can be displayed. User 4 is displayed in a reverse staircase pattern from the first to the third layer. Therefore, it is possible for the operator or the like to understand at a glance which hierarchy the displayed delivery partner belongs to.

The "delivery partner code" displayed at the leftmost of the display items is a code given to each user 4. FIG. In this example, an 8-digit code is assigned as a base, and in the case of "Aki △ Industry Co., Ltd.", it is "10112010".

As described above, the code assigned to the customer on the first layer is used in the third layer, such as the transit destination on the second layer, by increasing the number of digits for the final destination on the third layer. In this example, a code of "1011201001" with two digits added to the end is assigned to the Tokyo branch.

Furthermore, a code of "101120100101" is added to the end of the code of the Tokyo branch on the second layer by adding two digits to the business office, which is the final destination. However, since it is necessary to distinguish between delivery destinations belonging to the same hierarchy, three different codes "101120100101" to "101120100103" are assigned to each of the three sales offices in this example.

The user information 186 has been described as an example of the method of storing in the storage unit 18 by hierarchization. Information about the displayed menu may be hierarchically stored.

For example, when the store 2 purchases gas, suppliers and the like may be hierarchized and stored. For example, some filling factories 3 (manufacturers) have a plurality of filling factories 3 for each type of gas. When the store 2 issues a gas filling request to such a manufacturer, the request destination (supplier) is the manufacturer. However, depending on the type of gas, it is conceivable that only the name of the filling plant 3 is described on the delivery note when the requested gas is delivered.

In such a case, the supplier and the actual filling factory (warehousing destination) will be different, and from the point of view of dealer 2, it seems that the delivery was received from a party that did not request gas filling. It looks like

However, as described above, the vendor and the receiving destination are associated with each other, for example, "0 vendor", "1 receiving destination 1", and "2 receiving destination 2", and stored in a hierarchical manner. This facilitates confirmation when a gas container filled with gas is delivered. Moreover, since it becomes clear from where the delivered gas container was delivered by storing in this way, it is also useful when returning the gas container owned by the filling factory 3 .

[motion]
Next, as for the flow in which the store 2 executes the gas container management process using the gas container management device 1, a series of flow from the receipt of the shipment request from the user 4 to the shipment by the store 2 will be taken as an example. are explained below.

That is, by causing the gas container management device 1 to execute a gas container management program stored, for example, in the storage unit 18 in the gas container management device 1 provided in the store 2, various processes described below can be performed. done.

6 to 14 are flowcharts showing the flow of processing when gas container management is performed using the gas container management device 1 according to the embodiment of the present invention. Of these, the flowchart in FIG. 6 shows a rough flow of the series of flows described below. On the other hand, FIG. 7 and subsequent figures are flow charts used to explain each flow shown in FIG. 6 in detail.

In each flowchart used in the following explanation, in addition to the flow of processing in the gas container management device 1, actions of a collection and delivery staff, for example, are also described to facilitate understanding.

Also, although "user 4" is described here, as described above, the user information 186 of the gas container management device 1 stores user 4 in three layers. Therefore, the supplier stored in the first layer, the transit destination and management destination stored in the second layer, and the final destination stored in the third layer are all related to the gas cylinder. , corresponds to user 4.

Here, in the flow of processing, user 4 has details of user 4, such as, for example, an order is received from a business partner in the first hierarchy, and the destination to which the gas cylinder is delivered based on the order is the final destination. may be different. However, in the following, for convenience of explanation, those who are related to the gas container on each level are collectively referred to as user 4 .

First, with reference to FIG. 6, a series of flow from the receipt of a shipment request from the user 4 to the shipment by the store 2 will be roughly described. In preparation for an order from the user 4, the store 2 first purchases. In other words, this is a process in which the store 2 stocks the products in its own store (ST10). The store 2 receives an order for gas from the user 4 (accepts the order) while stocking the gas container filled with the gas (ST30).

Based on the order from the user 4, the store 2 arranges the gas (gas container), which is the product, and delivers (delivers) it from the store 2 to the user 4 (ST50). At this time, along with the delivery, the unnecessary gas container is collected from the user 4 (ST70).

In preparation for the next order from user 4, store 2 collects (accepts) gas containers from user 4, and stores empty gas containers according to their ownership categories. and request the filling factory 3 to fill a certain gas container with gas (ST90).

At the filling factory 3, which has been requested to fill the gas by the store 2, the gas container is filled with the gas according to the request (ST110).

In such a flow, the gas is delivered from the store 2 to the user 4, and the gas container is circulated among the store 2, the filling plant 3, and the user 4 in order.

Next, detailed processing in each flow will be described below along with a series of rough flows from when the above-mentioned store 2 receives a shipping request from the user 4 to shipping. First, there is a flow in which the store 2 stocks up in preparation for an order from the user 4 .

For example, if the user 4 is a new customer, the store 2 ships (delivers) a gas container filled with gas in response to a request from the user 4 . And from the next request, we will deliver in the form of exchanging the empty gas container for the filled gas container. Therefore, the store 2 must have gas containers filled with gas to be delivered to the user 4 in advance as an inventory.

FIG. 7 shows a flow for the store 2 to stock inventory among the flow of processing when executing gas container management using the gas container management device 1 according to the embodiment of the present invention. First, the store 2 requests (orders) filling of the gas container with gas from the filling factory 3 (ST11). The filling factory 3 fills the gas container based on the request, and the flow of this process will be described later.

When the gas container is filled with gas at the filling factory 3 , the gas container is delivered from the filling factory 3 to the store 2 . From the point of view of the store 2, this means that the gas container filled with the ordered gas has arrived, and the store 2 has purchased the gas (ST12).

Then, the store 2 that has purchased the gas starts warehousing processing for receiving the gas container filled with the product gas. First, the store 2 checks the request destination to confirm whether or not the received gas container was received from the supplier to whom the gas filling request was requested (ST13).

That is, if the gas container has been received from the requesting party that issued the order, the requesting party and the filling factory 3 (receipt destination) where the gas was filled described in the slip match (YES in ST13). On the other hand, as described above, when filling gas, the supplier may differ from the receiving destination (NO in ST13). Therefore, in such a case, it is confirmed whether or not the gas container was actually delivered by the supplier who requested the filling of the gas (ST14).

As a specific confirmation process, for example, when the supplier and the receiving destination are hierarchized and stored as described above, the receiving destination etc. It is checked whether or not it is stored in association with the destination.

Specifically, the operator inputs the information of the storage destination described in the slip from the input unit 15 of the gas container management device 1 . Based on the input, the security information acquisition unit 191 accesses the filling plant information 185 and extracts information about the related filling plant 3 . The extracted information is displayed on the display section 16 via the notification section 192 . As described above, when the information is hierarchically stored, the relationship between the supplier and the receiving destination can be grasped at a glance, as shown in the screen example of FIG. 5, for example.

If the confirmation is obtained (YES in ST15), the process proceeds to the next process. On the other hand, if the confirmation is not obtained (NO in ST15), the data of the request destination is corrected (ST16).

For example, if the dealer 2 fills its own gas container with gas and delivers it, it can achieve its intended purpose of filling the gas container with the specified gas even if the request destination does not match. . Therefore, if the request destination does not match, that is, the information of the request destination that issued the filling request registered in the gas container management information 182 and the information of the delivery source that actually delivered the gas container do not match. Also, priority is given to information on gas containers filled with gas, which are actual products.

In other words, if the request destination does not match, the information of the request destination is changed based on the information of the gas cylinder actually delivered, and the data of the request destination for filling the gas cylinder concerned is changed to the delivery source (new request destination). process to change to the data of

Then, the process returns to step ST13 for confirming whether or not the request destinations match. Here, as described above, the data of the requester has already been corrected to the data of the delivery source that delivered the gas cylinder to be purchased, so it is assumed that the requester matches (ST13 YES), and the next processing is performed. move to

If the request destination is confirmed, then it is confirmed who owns the gas container. Specifically, it is checked here whether or not the corresponding gas container is owned by the manufacturer (filling factory 3) (ST17).

In other words, from the point of view of the store 2, when the gas container is filled with gas at the request of the store 2 and enters the warehouse, if the gas container is owned by the filling factory 3, the gas container can be borrowed from the filling factory 3. become. Therefore, if the owned gas container is owned by the filling factory 3 (YES in ST17), it is accepted as the gas container owned by the filling factory 3 (ST18). Then, the gas container management device 1 sets the ownership category of the gas container in question in the gas container management information 182 to "1" and processes the display as "borrowed container" (ST19).

On the other hand, for example, if the dealer 2 or the dealer 2 requests the filling factory 3 to fill the gas container owned by the user 4 (NO in ST17), this is the company's own company. Since the owned gas container is returned (stored) after being filled with gas, the gas container management device 1 treats the order (filling request) as accepted (ST20).

This completes the warehousing process based on the order placed by the store 2 to the filling factory 3 (ST21). As a result, the store 2 can keep the gas in stock and prepare for an order from the user 4 .

Next, the flow when the store 2 receives a gas purchase request (order) from the user 4 (ST30 in FIG. 6) will be described. FIG. 8 and FIG. 9 show the processing when the gas container management device 1 according to the embodiment of the present invention is used to manage the gas containers, particularly when the store 2 receives an order from the user 4. is a flow chart showing the flow of

The store 2 receives (accepts) an order for gas purchase from the user 4 (ST31). Although any medium may be used to receive an actual order, the content of the received order is input to the gas container management device 1 .

The gas container management device 1 draws up a delivery schedule based on the content of the received order (ST32). Here, "delivery schedule planning" is a process of putting together various requests from various users 4 into a delivery schedule.

As described above, the gas to be delivered requires consideration of safety, and the gas container is a heavy object. For this reason, it is not possible to deliver goods at the right time, and the safest and most efficient delivery is required. For this reason, the first thing that the dealer 2 thinks about when receiving an order is delivery (arranging a truck).

Note that the delivery schedule includes not only delivery to a specific user 4 but also delivery to a plurality of users 4 in sequence. Also, the delivery schedule is drafted and created for each collection/delivery worker or truck.

When planning the delivery schedule, the security information acquisition unit 191 determines whether gas containers filled with gas whose mixed loading is prohibited are mixed on the same truck. (ST33).

This is because, as described above, it is not permitted to mix different types of gases on a transport vehicle, and this is a matter that must be complied with when transporting gas, which is a dangerous substance. Therefore, the type of gas that must be delivered to the final delivery destination is checked to determine whether mixed loading is possible.

As a result of the determination, if there is a gas type that cannot be mixed-loaded as a result of the determination, it is determined that mixed-loading is not possible (NO in ST33), and the security information acquisition unit 191 causes the display unit 16 to display a warning regarding mixed-loading via the notification unit 192 ( ST34), prompting the operator to distribute the gas cylinders to be delivered to a plurality of trucks (change the truck allocation).

On the other hand, if there is no gas type for which mixed loading is not permitted among the gas types to be delivered (YES in ST33), the on-vehicle weight is further taken into consideration with the loadable weight of the truck scheduled to be used for delivery. It is confirmed (ST35). Information about the loadable weight of the truck is stored in the store information 184, for example.

As a result of the security information acquisition unit 191 accessing the store information 184 and acquiring and confirming the information on the loadable weight, there is a possibility that the loadable weight of the truck will be exceeded if all the gas containers scheduled for delivery are loaded. In some cases (in the case of overloading) (NO in ST35), the security information acquisition unit 191 causes the display unit 16 to display a warning regarding the vehicle weight (ST36). Then, the operator is urged to distribute the gas containers to be delivered to a plurality of trucks (to change the truck allocation).

On the other hand, when the safety information acquisition unit 191 determines that the on-vehicle weight is also less than the loadable weight of the truck (YES in ST35), next, the user 4 who placed the order has been traded with store 2 (ST37).

This check is to confirm whether or not a sales contract has been concluded between the so-called store 2 and the user 4 . For example, if the sales contract is not found after confirmation (NO in ST37), such as when the order is related to a new gas type with the user 4, a new contract is entered into, and the sales management information 183 Register (ST38) to create a state that enables gas transactions.

It should be noted that, depending on the store 2, unless a sales contract has been concluded with the user 4, even if an order is received, there are some stores that do not deliver the product. In this case, the process of confirming the presence or absence of the gas transaction shown in step ST37 is executed when the order is received.

On the other hand, if there is a sales contract between the store 2 and the user 4 (YES in ST37), then it is confirmed whether or not a notice is required for the type of gas to be delivered to the user 4. (ST39 in FIG. 9). If a notice that has not been made public so far or that has a well-known deadline is required (NO in ST39), a notice is created (ST40).

Specifically, the security information acquisition unit 191 of the control unit 19 acquires from the security management information 181 security information such as information related to well-known deadlines and information related to the delivery and receipt of well-known documents organized for each gas type. Then, the notification unit 192 causes the display unit 16 to display the acquired information related to publicity. The operator or the like confirms the process of registering a new gas container as described above and the security information required for each gas type and gas container presented in association with the process, and prepares a notice.

It should be noted that the security information acquisition unit 191 may collect the necessary security information as appropriate and automatically create the necessary public notice.

Then, if the notice is unnecessary (YES in ST39) or if the notice is created, it is further checked whether the storage amount of the user 4, who is the final destination of the scheduled delivery, is within the regulation. Confirmation is performed (ST41).

Specifically, the security information acquisition unit 191 acquires information on all gas containers that the user 4 has on hand from the sales management information 183, and also acquires from the user information 186 information on the amount of storage that can be stored by the user 4. Get information too.

Based on the information collected in this manner, the security information acquisition unit 191 calculates the amount of storage at the user 4 when a new gas container is delivered to the user 4 this time. It is determined how much it will be and whether this storage amount exceeds the allowable storage amount.

Specifically, first, the security information acquisition unit 191 grasps the amount of gas filled in the gas container to be delivered, and also grasps the amount of gas currently stored at the user 4 who is the final destination of the notification. , find the total amount of both.

When obtaining the total amount, it is conceivable that the unit of the requested filling amount differs depending on the gas type in the information at the time of ordering. That is, as described above, there is a possibility that multiple units may coexist depending on the type of gas and trade practices.

Therefore, units that may be different for each ordered gas type are unified into one unit using, for example, a conversion table stored in the storage unit 18 . The control unit 19 performs conversion using the conversion table and calculates the total amount. Then, compare the total amount of storage at the final delivery destination, including the amount of gas ordered and delivered, with the permitted storage amount.

If it is determined by the security information acquisition unit 191 that the storage amount allowed by the user 4 will be exceeded by the delivery (NO in ST41), the empty gas when the delivery to the user 4 will be carried out. Assuming that the container will be collected, the user 4 reconfirms the storage amount (ST42).

In other words, the storage amount for the user 4 is calculated based on the capacities of all the gas containers stored by the user 4 . Therefore, even if there is an empty gas container, the storage amount is calculated on the assumption that it is filled with gas. Therefore, for example, the storage amount is confirmed again assuming that there is no empty gas container to be recovered in exchange for the newly delivered gas container.

As a result of the reconfirmation, if the storage amount is within the specified range (YES in ST43), it is determined that the newly filled gas container can be delivered. On the other hand, if the storage amount exceeds the prescribed amount even after such processing is performed (NO in ST43), the delivery to the user 4 is stopped (ST44).

As a result of confirming the storage amount at the user 4 who is the delivery destination, if it is within the regulation (YES in ST41, YES in ST43), the storage amount is within the range stipulated in Article 9-3 of the Fire Service Act. A confirmation is made as to whether or not it fits (ST45).

That is, if the type of gas delivered to user 4 this time includes a type of gas regulated by the Fire Service Act, such as ammonia, acetylene gas, etc., the location, that is, the final destination can be stored only within the storage amount permitted by the user 4 .

Therefore, first, the control unit 19 extracts from the user information 186 the information on the address of the user 4 set as the final destination or the information on the storage amount via the security information acquisition unit 191 .

Then, grasp the storage capacity permitted for storage of gas containers. Then, the amount of gas filled in the gas container scheduled to be delivered is grasped, and the amount of gas currently stored at the final delivery destination is grasped, and the total amount of both is obtained. The method for obtaining the total amount of gas is as described above.

If the security information acquisition unit 191 determines that the delivery will exceed the allowable amount stipulated in the Fire Service Act (NO in ST45), when the user 4 goes to deliver the empty Assuming that the gas container will be collected, the user 4 reconfirms the storage amount (ST46).

As a result of the reconfirmation, if the storage amount is within the specified range (YES in ST47), it is determined that the newly filled gas container can be delivered. On the other hand, if the storage amount exceeds the specified amount even if such processing is performed (NO in ST47), the delivery is stopped (ST48).

As described above, the security information acquisition unit 191 confirms various conditions as described above when planning the delivery schedule, and by satisfying all the conditions, delivery from the store 2 to the user 4 who is the final destination is possible. Become. Therefore, a gas container delivery instruction sheet is created based on the finalized delivery schedule (ST49).

In addition, as described above, when the gas container is delivered to the user 4, the empty gas container is collected at the same time. Therefore, a gas container recovery instruction sheet for recovering the gas container is also created.

Next, referring to FIG. 10, the flow of delivery of gas (gas container) ordered by the store 2 to the user 4 (ST50 in FIG. 6) will be described. FIG. 10 shows a flow of processes when the gas container management device 1 according to the embodiment of the present invention is used to manage the gas containers, particularly when the store 2 delivers the gas containers to the user 4. It is a flow chart showing.

As described above, the store 2 receives an order from the user 4 and uses the gas container management device 1 to create a gas container delivery instruction sheet while confirming various security information. Therefore, when the collection and delivery staff from the store 2 deliver the gas bottles to the user 4, the required gas bottles are taken out from the warehouse based on the gas bottle delivery instructions (ST51).

That is, the collection and delivery staff takes out the gas container from the warehouse of the store 2 and loads it onto the truck (ST52). During loading, the courier performs a pre-delivery check on each gas canister. For example, the collection and delivery staff uses the portable information terminal 5 to read the recording medium 65 attached to the gas container 6, or input the container symbol/container number 63 stamped on the gas container 6. , check each one.

Specifically, it is executed by confirming the gas container management information 182 of the gas container 6 from the container symbol/container number 63 of the gas container 6 . First, it is checked whether or not the gas container to be delivered is filled with the necessary gas (ST53). This is to avoid delivering an empty gas bottle to user 4 .

As described above, when an empty gas container is filled with gas, the warehousing process described using the flowchart shown in FIG. 7 is executed. Therefore, for example, if the status of "filling and storage" is not displayed (NO in ST53), it means that the storage processing for the gas container concerned has not been completed. Therefore, after performing necessary processing such as confirming the movement status of the gas container or confirming the actual gas container (ST54), the collection and delivery staff confirm whether the gas container is filled with gas again. Confirm whether or not

On the other hand, if the gas container to be checked is a delivered gas container and has been filled (YES in ST53), the status "Filled in stock" is displayed. In this case, it is recognized that the gas container is filled with a predetermined gas.

Therefore, in such a case, the security information acquisition unit 191 further confirms the material of the gas container. If the gas container is made of FRP, it is checked whether it is before the disposal date of the FRP container (ST55). This is because, as described above, if the gas container is an FRP container, it will be absolutely discarded 15 years after its manufacture.

As will be described later, when the gas container is an FRP container, the confirmation of the expiration date for disposal is also confirmed when the gas container is filled with gas at the filling factory 3 . However, the confirmation processing here is confirmation processing of the expiration date at the time of filling. That is, for example, in the case of a gas container whose disposal deadline is approaching, even though it was before the disposal deadline when it was filled at the filling factory 3, the gas container filled with gas from the filling factory 3 is purchased by the store 2, and then delivered to the user 4. It is possible that the disposal deadline will arrive before the

Therefore, by confirming the disposal deadline when delivering to the user 4 again, it is possible to avoid overlooking the disposal deadline and to thoroughly comply with laws and regulations. Therefore, if the disposal deadline has been reached as a result of confirmation (NO in ST55), the gas container is disposed of (ST56).

If the disposal deadline has not yet arrived at this point (YES in ST55), it is further confirmed whether or not the container manager matches the user 4 who placed the order with the store 2 (ST57). This is a check to prevent the user 4 from mistakenly delivering a gas container that is not under their control.

For example, the security information acquisition unit 191 acquires information about the user 4 who received the order from the sales management information 183, and acquires information about the container manager of the gas container from the gas container management information 182. Determine whether or not As a result, if the user 4 to whom the gas container is to be delivered does not match the container manager of the gas container (NO in ST57), the container manager of the gas container is checked again (ST58).

There is no problem if the confirmation is obtained and they match (YES in ST59), but if the user 4 who is the delivery destination and the container manager do not match (NO in ST59), the delivery of the gas container is canceled. (ST60).

As a result of the confirmation process described above, if there is no problem, the gas container will be delivered to the user 4 (final delivery destination) who ordered the gas (ST61).

Next, the flow (ST70 in FIG. 6) of collecting the empty gas container 6 in exchange for the gas container delivered to the user 4 by the store 2 will be described. FIG. 11 and FIG. 12 show, among the processes when managing gas containers using the gas container management device 1 according to the embodiment of the present invention, especially when the store 2 receives an empty gas container from the user 4. It is a flowchart which shows the flow which collect|recovers.

As described above, gas containers for which various check items have been confirmed, such as that the gas is filled, are delivered to the respective users 4 who are the final destinations based on the gas container delivery instructions. At this time, in many cases, the delivered filled gas container is replaced with the exhausted and emptied gas container 6, and the empty gas container is collected. The collection and delivery staff collects the corresponding gas container according to the gas container collection instruction created together with the gas container delivery instruction (ST71).

Specifically, when loading the gas cylinders onto the truck, the container symbols/numbers 63 of the gas cylinders are read one by one by the portable information terminal 5, and the gas cylinders are read one by one, as in the case of loading the gas cylinders onto the truck for delivery. Proceed with confirmation for each container.

First, it is confirmed whether or not the gas container to be loaded onto the truck is to be collected (ST73). This confirmation is made, for example, by the security information acquisition unit 191 accessing the gas container management information 182 based on the container symbol/container number 63 .

That is, it is confirmed whether or not the user 4 requested that the previously delivered gas container be collected. As for the store 2, if it is a gas container delivered by itself, it can be collected without any problem (YES in ST73). On the other hand, although there is a request for collection, if the gas container was delivered by another store 2 and not delivered by the customer himself/herself, it cannot be collected (NO in ST73).

However, as a result of confirmation, even if the gas container is not subject to collection, for example, rather than asking the store 2 that delivered this gas container to fill it with gas, I would like to request that it be collected and filled at the same time. There is also a user 4 named . Therefore, it is conceivable to collect gas containers that are requested to be filled even if they are not subject to collection.

Therefore, if it is confirmed that there is a filling request again (YES in ST74), the gas containers are subject to recovery, and the recovery is stopped for other gas containers (ST75).

Next, if the gas container is an FRP container, it is checked whether it is before the expiration date (ST76). This is to check whether or not the FRP container disposal deadline has arrived while the user 4 is using it. is displayed on the portable information terminal 5. If the disposal deadline has passed (NO in ST76), the collection and delivery staff reports to the user 4 that the gas container is subject to disposal, and performs disposal processing after collection (ST77).

On the other hand, if the disposal deadline has not yet passed (YES in ST77), the owner of the gas container is confirmed (ST78 in FIG. 12). Here, it is confirmed whether or not the ownership category of the container is "2", that is, whether or not the target gas container is owned by the user 4 or not. In addition, regarding the confirmation process here, it is not only the user 4 who is the final destination stored in the third hierarchy, but also whether or not it corresponds to the user 4 who is the business partner stored in the first hierarchy, for example. may also be confirmed.

As a result of confirmation, if it is confirmed that it is the gas container of user 4 (YES in ST78), based on the safety management information 181, is the gas container before the filling deadline, that is, before the inspection deadline? Whether or not is checked (ST79). Collecting an empty gas container basically means that the collected gas container must be refilled with gas.

Therefore, if it is before the next inspection date at this time, it can be confirmed that filling is possible (YES in ST79), so the control unit 19 changes the status of the collected gas container to "filling storage". Convert automatically (ST80). That is, since the store 2 collects the gas container owned by the user 4 to fill it with gas, the collecting action is an act of depositing the gas for filling the gas container.

On the other hand, if the inspection deadline has passed, that is, the inspection deadline has passed and the inspection deadline has passed (NO in ST79), the gas container to be collected in the gas container management information 182 status is changed to "inspection pending", and the display on the display unit 16 of the portable information terminal 5 and the gas container management device 1 is changed to "inspection pending" (ST81).

This is because the gas container to be collected belongs to the user 4 in these processes. On the other hand, when the gas container to be collected is owned by the company (dealer 2) or owned by the filling plant 3 (manufacturer), processing different from the processing described above is performed.

In other words, if the gas container to be collected is owned by the store 2 or the filling factory 3 (NO in ST78), it is confirmed whether it is within the time limit for filling, that is, before the inspection time limit. is executed (ST82), and if the inspection deadline has passed (NO in ST82), an inspection warning prompting inspection is displayed on the portable information terminal 5 or the gas container management device 1 (ST83). .

The reason why the process is different from the case of the gas container owned by the user 4 is that the collection of such a gas container does not correspond to the "custody" from the user 4 . This is because if a warning is issued to call attention to the store 2 or the filling plant 3 via the store 2, immediate action can be taken.

By completing all the confirmation processes as described above, the check for collecting the gas container from the user 4 is completed, and the gas container can be collected (accepted) (ST84). At that time, it is also possible to issue a document such as a “container receipt” to the user 4 .

Next, the flow after the store 2 collects the gas container from the user 4 (ST90 in FIG. 6) will be described. FIG. 13 shows a process for managing gas containers using the gas container management apparatus 1 according to the embodiment of the present invention, particularly after the store 2 collects an empty gas container from the user 4. is a flow chart showing the flow of

The store 2 collects the gas container to be collected from the user 4 and carries it to its own warehouse, for example. These recovered gas containers need to be refilled with gas or sent for inspection, for example. Here, each such processing will be described.

When the store 2 collects the gas containers from the user 4, it checks what kind of processing is to be performed next for each one. That is, confirmation is made as to whether the collected gas container should be returned or requested (ST91).

It should be noted that "return" here means that if the gas container is owned by the filling factory 3 as confirmed at the time of collection, the store 2 that has taken over the gas container from the user 4 returns the gas container to the filling factory 3. means to return. Also, "request" means "request" from the store 2 to the filling factory 3 for filling or inspection.

However, before executing these processes, it is first confirmed whether or not the recovered gas container is empty (ST92). An operator or the like confirms the condition of each collected gas container by using the container symbol/container number.

That is, since the gas container collected from the user 4 is exchanged for a newly delivered gas container filled with gas, it is generally considered to be empty. However, for example, when the product is received as "returned goods", the gas container remains filled with gas. Alternatively, even an empty gas container may be a gas container that has been subject to an accident or malfunction, for example.

For gas containers in such a state (NO in ST92), the gas container management information 182 does not indicate that the gas container is empty, indicating that the gas container is empty. Therefore, the collection and delivery staff confirms the current status of each gas container, and stops returning gas containers that are not "empty" in the data to the filling factory 3 (ST93). As for the gas cylinders whose return has been canceled, appropriate measures such as disposal will be taken depending on the situation.

On the other hand, if it is confirmed that the collected gas container is empty (YES in ST92), then the ownership category is checked to see who owns the gas container. Here, it is confirmed whether or not the gas container is owned by the filling factory 3 (ownership classification is "1") (ST94).

The safety information acquisition unit 191 confirms whether or not the gas container is owned by the filling plant 3 based on the extracted gas container management information 182. If it is confirmed that the gas container is owned by the filling plant 3, (YES in ST94), the process of returning to the filling factory 3 is performed (ST95).

By this process, the gas container owned by the filling factory 3 collected from the user 4 is returned to the filling factory 3 by the store 2 . Note that the gas container itself is separately delivered from the store 2 to the filling factory 3 .

On the other hand, if the ownership classification is other than "1", that is, if the gas container is owned by the store 2 or owned by the user 4, first, before the deadline for filling, that is, before the inspection deadline, Whether or not there is is confirmed (ST96).

If it is determined that the filling time limit has not passed (YES in ST96), it means that the gas container can be filled with gas. request” (ST97).

That is, as described above, the gas containers collected by the store 2 from the users 4 must be filled with gas and stocked by the store 2 in preparation for future orders from the users 4 .

Therefore, in the shop 2, among the gas containers collected from the user 4, if the gas container owned by the shop 2 or the user 4 is within the filling time limit, the gas container management information 182 is set to "filling request", and filling is requested to the filling factory 3 as appropriate. That is, the store 2 orders the filling factory 3 to send the gas container collected from the user 4 and have it filled with gas.

On the other hand, if it is not within the filling period, that is, if the inspection deadline has passed (NO in ST96), the gas container management device 1 first changes the status of the gas container in the gas container management information 182 to "inspection request." ” (ST98).

After that, the inspection process for the gas container is executed (ST99). This status remains until the inspection process is completed (NO in ST100). On the other hand, if the inspection is completed (YES in ST100), that effect is registered in the gas container management information 182, and the status becomes "inspection returned" (ST101). In this state, the gas container can be filled with gas. Therefore, as shown in step ST97, the status is changed to "filling request" again, and an order is placed to the filling factory 3 to fill the gas container with gas.

As described above, the store 2 fills the gas container with gas in preparation for an order from the user 4 and keeps it as an inventory. Deliver gas containers. At the same time, the gas container is collected from the user 4, and an order is placed with the filling factory 3 to refill the collected gas container with gas.

In this way, the gas cylinder circulates among the store 2, the filling factory 3, and the user 4. So far, along the flow of the gas cylinder centering on the store 2, the security management information 181, the gas cylinder It has been described how the management information 182 and the sales management information 183 cooperate with each other to appropriately provide security information to the operator or the like.

On the other hand, as described above, the filling plant 3 also uses the gas container management device 1 to manage the gas containers. Next, the flow (ST110 in FIG. 6) in the filling factory 3 for filling the gas container 6 with gas based on the order from the store 2 will be described.

FIG. 14 is a flow chart showing the flow of filling the gas containers with gas, especially at the filling factory 3, among the processes when managing the gas containers using the gas container management device 1 according to the embodiment of the present invention. is. At the filling factory 3, when the empty gas container is brought in from the store 2, the filling process for the gas container to be filled is started (ST111).

At the filling factory 3, first, it is confirmed whether or not the gas container to be filled is an FRP container and is before the disposal deadline (ST112). The filling factory 3 is provided with the gas container management device 1 as described above to manage the gas containers. Therefore, the safety information acquisition unit 191 accesses the gas container management information 182 of the gas container and checks the expiration date of disposal of the gas container.

As a result, if it is not before the disposal deadline (NO in ST112), the disposal deadline has arrived, so the operator is notified via the notification unit 192 to perform disposal processing for this gas container. (ST113).

On the other hand, if it is before the disposal deadline (YES in ST112), it is confirmed whether or not the filling deadline, that is, the inspection deadline has arrived (ST114). This is a check item when the gas container is not an FRP container.

This confirmation item is also confirmed by the gas container management information 182, but if the filling time limit has passed and inspection is necessary (NO in ST114), the filling process is stopped (ST115).

It should be noted that the gas container determined in this manner may actually be transferred to inspection processing, or may be discarded according to the owner's intention. Accordingly, detailed processing differs depending on which processing is performed in detail.

Next, if the gas container is within the filling time limit (YES in ST114), the gas container will be filled with gas. A gas container to be filled with the gas type is arranged in the vicinity of the pedestal. Here, the gantry is a device for filling the gas container with gas, and in many cases, different filling locations are prepared for different types of gas. In other words, the pedestals are provided collectively for each type of gas.

A recording medium is provided for each pedestal or near the pedestal. Various types of information such as gas species and filling pressure are recorded on the recording medium. Therefore, the gas container management device 1 in the filling factory 3 first acquires various information such as the type of gas through the recording medium, and also acquires information about the gas container to be filled. Then, the security information acquisition unit 191 compares the two pieces of information and confirms whether or not they match.

That is, first, it is confirmed whether or not the information on the gantry and the information on the gas container with respect to the type of gas match (ST116). As a result, if they do not match (NO in ST116), the filling process is stopped (ST117).

Here, in addition to cases in which the type of gas itself is different, such as oxygen and nitrogen, for example, "liquid oxygen" and "gaseous oxygen" are the same gas species, but their states (phases) are different. are also determined to be inconsistent.

On the other hand, if the gas types match (YES in ST116), then the security information acquisition unit 191 confirms whether or not the information on the gantry and the information on the gas container with respect to the filling pressure match (ST118). As a result, if they do not match (NO in ST118), the filling process is stopped (ST119).

If the filling pressures match (YES in ST118), all the conditions necessary for filling the gas container have been satisfied, and the process of filling the gas container with gas is executed. (ST120). The above is the flow of the process of filling the gas container entrusted to the filling factory 3 by the store 2 with gas.

If the information on the pedestal and the information on the gas container do not match the type of gas and the filling pressure, the filling is stopped. That is, when the gas species are different, for example, when a gas container to be filled with nitrogen is attached to a frame for filling oxygen, the filling process is absolutely stopped (prohibited). This is because there is a risk of explosion or the like when different gas types are used.

On the other hand, regarding the filling pressure, if the filling pressure in the frame is higher than the filling pressure allowed by the gas container, it is dangerous and such a filling process is not permitted. There may be no danger if the filling pressure at the cradle is lower than Therefore, when the filling pressures do not match in this way, filling is not uniformly stopped, and confirmation is made to confirm that there is no danger.

As described above, when the gas container management device 1 is used to manage the gas containers, appropriate safety information is automatically provided. Therefore, by using the information necessary for the management of the gas cylinder, it is possible to manage the security information reliably in daily processing without being particularly conscious of it, and to reflect the security information in the management of the gas cylinder.
