It should be noted that not all information is necessarily registered in the management table 432. For example, on the delivery date, registration may be performed only when the storage is the cylinder bestker 60.

FIG. 6 is a sequence diagram showing a flow of registration processing of the gas container B of the gas container management system 1 according to the first embodiment. The process of FIG. 6 is executed when the gas container B is delivered.
The imaging unit 31 of the communication device 30 acquires imaging data by imaging the gas container B in response to a user operation (step S101). The imaging unit 31 stores the acquired imaging data in the storage unit 32 via the control unit 35. The control unit 35 acquires container information from the imaged data by analyzing the imaged data stored in the storage unit 32. Specifically, the control unit 35 converts the characters included in the imaged data into text data by performing image analysis of the imaged data by OCR. The control unit 35 displays the container information converted into text data on the display unit 33 (step S102). The control unit 35 selects predetermined information from the container information displayed on the screen. For example, the control unit 35 selects information on the container number, gas name, gas concentration, quality assurance deadline, filling amount, and manufacturing date as predetermined information from the container information. The user may select information from the container information displayed on the screen. If the container information displayed on the screen is incorrect, or if the characters are not recognized and cannot be read, the user inputs essential information via the operation unit 34. Further, the control unit 35 may select essential information from the container information converted into text data and display it on the display unit 33.

The communication unit 36 transmits the selected and input essential information to the management device 40 according to the operation of the user (step S103).
The communication unit 41 of the management device 40 receives the essential information transmitted from the communication device 30. The communication unit 41 outputs the received essential information to the control unit 45. The control unit 45 registers the output essential information in the container table 431 (step S104). For example, when the required information includes information on the container number, gas name, gas concentration, quality assurance deadline, filling amount, and manufacturing date, the control unit 45 controls the container number, gas name, concentration, and quality of the container table 431. Register the acquired required information in the items of warranty period, initial filling amount, and manufacturing date. After that, the management device 40 transmits the specific information to the writing device 50 in response to the user's operation (step S105). Here, it is assumed that the management device 40 transmits the container number selected according to the operation of the user to the writing device 50 as specific information.

The writing device 50 acquires the specific information transmitted from the management device 40. The writing device 50 temporarily stores the acquired specific information (step S106). The writing device 50 writes specific information in the electronic tag 90 according to the operation of the user (step S107). When a plurality of specific information is registered in the writing device 50, the user selects desired specific information and causes the selected specific information to be written to the electronic tag 90. As a result, specific information is recorded in the electronic tag 90. The user attaches the electronic tag 90 on which the specific information is written to the delivered gas container B (step S108).

Then, the user stores the gas container B to which the electronic tag 90 is attached in the cylinder bestker 60 (step S109). The reading device 61 provided in the cylinder 60 is reading the electronic tag 90 periodically (for example, every 3 hours, every day, etc.) or at a predetermined timing (step S110). When the electronic tag 90 is in the cylinder 60, the reading device 61 acquires the specific information stored in the electronic tag 90. At this time, the reading device 61 also acquires the identification information (tag identification information) of the electronic tag 90 in association with the specific information. The reading device 61 outputs the acquired specific information and the identification information of the electronic tag 90 to a communication unit (not shown). The communication unit transmits information including specific information, identification information of the electronic tag 90, identification information of the cylinder 60, and identification information of the reading device 61 to the management device 40 (step S111).

The communication unit 41 of the management device 40 receives the information transmitted from the cylinder bestker 60. The communication unit 41 outputs the received information to the control unit 45. The control unit 45 registers the output information in the management table 432 (step S112). Specifically, the control unit 45 reads the management table 432 from the storage unit 43. The control unit 45 selects the record corresponding to the acquired storage identification information and reader identification information from the records of the read management table 432. The control unit 45 registers the acquired tag identification information and specific information in the tag identification information and specific information items of the selected record. Further, if the value is not registered in the item of the import date of the selected record, the control unit 45 may register this date as the import date.
By the above processing, the delivered gas container B and the storage storage in which the gas container B is stored are registered in association with each other.

FIG. 7 is a sequence diagram showing a processing flow when the gas container B of the gas container management system 1 according to the first embodiment is moved. The process of FIG. 7 is performed when the gas container B is moved from the cylinder cabinet 60 to the cylinder cabinet 70.
When the cylinder cabinet 70 is refilled with the gas container B, the user carries out the gas container B from the cylinder cabinet 60 (step S201). The reading device 61 provided in the cylinder 60 is reading the electronic tag 90 periodically or at a predetermined timing (step S202). However, it is assumed that the electronic tag 90 is not present at the timing when the reading device 61 reads the electronic tag 90. In this case, the reading device 61 cannot acquire specific information from the electronic tag 90. Therefore, the reading device 61 does not transmit information to the management device 40 (step S203). Alternatively, the communication unit transmits information including two pieces of information, the identification information of the cylinder bestker 60 and the identification information of the reading device 61, to the management device 40.

The control unit 45 of the management device 40 normally cannot obtain the information at the timing when the information is obtained from the cylinder bestker 60, or the identification information and reading of the cylinder bestker 60 are added to the information transmitted from the cylinder bestker 60. When only two pieces of identification information of the device 61 are included, the control unit 45 determines that the gas container B has been carried out from the cylinder bestker 60. That is, when the specific information associated with the storage is not obtained for a predetermined period, the control unit 45 determines that the gas container B has been carried out from the cylinder bestker 60. It should be noted that such a determination is the same for the cylinder cabinet 70. Specifically, when the gas container B is housed in the cylinder cabinet 70, specific information should be acquired from the reading device 71 as in the case of the cylinder cabinet 60. However, when the gas container B is carried out from the cylinder cabinet 70, the specific information is not acquired from the reading device 71. Therefore, as in the case of the cylinder cabinet 60, when the control unit 45 contains only two pieces of information, the identification information of the cylinder cabinet 70 and the identification information of the reading device 71, the gas container B is carried out from the cylinder cabinet 70. Judged as Then, the control unit 45 updates the management table 432 (step S204). Specifically, the control unit 45 reads the management table 432 from the storage unit 43. The control unit 45 selects the record corresponding to the acquired storage identification information and reader identification information from the records of the read management table 432. The control unit 45 deletes the information that could not be obtained from the tag identification information and specific information items of the selected record.

A plurality of gas containers B can be stored in one cylinder cabinet 70 and one cylinder cabinet 70. Therefore, in the management table 432, a plurality of tag identification information and specific information are associated with one cylinder cabinet 70 and one cylinder cabinet 70. Therefore, when a plurality of tag identification information and specific information are associated with one cylinder cabinet 70 and the cylinder cabinet 70, even if one tag identification information and specific information cannot be obtained, other tag identification information can be identified. Information and specific information can be obtained. Therefore, the control unit 45 manages the information associated with the storage by deleting the tag identification information and the information for which the specific information could not be obtained.

It is assumed that the user carries the gas container B carried out from the cylinder cabinet 60 into the cylinder cabinet 70 (step S205). The reading device 71 provided in the cylinder cabinet 70 reads the electronic tag 90 periodically or at a predetermined timing (step S206). When the electronic tag 90 is in the cylinder cabinet 70, the reading device 71 acquires the specific information stored in the electronic tag 90. At this time, the reading device 71 also acquires the identification information (tag identification information) of the electronic tag 90 in association with the specific information. The reading device 71 outputs the acquired container number and the identification information of the electronic tag 90 to a communication unit (not shown). The communication unit transmits information including specific information, identification information of the electronic tag 90, identification information of the cylinder cabinet 70, and identification information of the reading device 71 to the management device 40 (step S207).

The communication unit 41 of the management device 40 receives the information transmitted from the cylinder cabinet 70. The communication unit 41 outputs the received information to the control unit 45. The control unit 45 updates the management table 432 according to the output information (step S208). Specifically, the control unit 45 reads the management table 432 from the storage unit 43. The control unit 45 selects the record corresponding to the acquired storage identification information and reader identification information from the records of the read management table 432. The control unit 45 registers the acquired tag identification information and specific information in the tag identification information and specific information items of the selected record. As a result, the control unit 45 updates the management table 432. Further, if the value is not registered in the item of the import date of the selected record, the control unit 45 may register this date as the import date.

The control unit 45 displays the contents stored in the storage unit 43 on the display unit 44 in response to the user's operation (step S209). 8 and 9 are views showing an example of a screen displayed on the screen of the display unit 44.

For example, the storage status display area 442 indicates where the gas container B is stored. A black circle indicates that the gas container B is housed. These displays are displayed by the control unit 45 referring to the management table 432.

In the acceptance information display area 443, information on the gas container B to be accepted from now on is displayed. “Done” in the acceptance information display area 443 indicates whether or not acceptance has been completed. Whether or not the acceptance is completed is determined by whether or not the target gas container B is stored in the cylinder bestker 60. When the target gas container B is housed in the cylinder bestker 60, the control unit 45 determines that the acceptance is completed. In this case, the control unit 45 makes the display mode of "finished" corresponding to the gas container B for which acceptance has been completed different from the display mode of "finished" corresponding to the gas container B for which acceptance has not been completed. For example, the control unit 45 may erase the display of “done” corresponding to the gas container B for which acceptance has been completed, or may paint black as shown in FIG. On the other hand, when the target gas container B is not housed in the cylinder bestker 60, the control unit 45 determines that the acceptance is not completed.

The storage amount display area 444 displays information on the total amount of gas stored in the room selected in the display selection area 441. The total storage capacity of high pressure gas is regulated by the relevant laws and regulations of high pressure gas. If more than the total storage amount stipulated by the relevant laws and regulations of high pressure gas is stored, notification is required.
In this way, by looking at the screen of the display unit 44, the user can grasp information such as the status of the storage in each room and the amount of gas stored at a glance.

When the user selects one gas container B displayed on the screen, the control unit 45 displays information about the selected gas container B as a pop-up 445 as shown in FIG. In the pop-up 445, information on the storage identification information, the tag identification information, the container number, the state, the filling amount, the manufacturing date, the quality assurance deadline, and the standard delivery date is displayed. The information displayed in the pop-up 445 is not limited to this, and any division method may be used as long as the information is stored in the management device 40. Here, the state represents the state of the gas container B at the time of selection. For example, whether or not the gas container B is currently used. When the gas container B is currently in use, the information of "supplying" is displayed as the state, and when the gas container B is not currently used, the information of "waiting" is displayed as the state. .. The standard delivery date represents the period until the gas container B of the same type as the selected gas container B is delivered. The standard delivery date may be stored in advance by the management device 40 for each gas type of the manufacturer.

When the cylinder cabinet 70 is correctly connected to the cylinder transport carriage 2-2, the cylinder cabinet 70 transmits connection completion information indicating that the connection is completed to the management device 40a (step S434). On the other hand, if the cylinder transporter 60 is not correctly connected to the cylinder transport carriage 2-1, the cylinder bestker 60 transmits error information indicating that the connection is not completed to the management device 40a. Here, it is assumed that the cylinder cabinet 70 and the cylinder transport carriage 2-2 are correctly connected.

The communication unit 41 of the management device 40a receives the connection completion information transmitted from the cylinder cabinet 70. The communication unit 41 transmits the received connection completion information to the operation terminal 100 (step S435).
The communication unit 101 of the operation terminal 100 receives the connection completion information transmitted from the management device 40a. Based on the connection completion information received by the communication unit 101, the control unit 103 inquires the user whether or not to carry the gas container Bf to be carried into the cylinder cabinet 70 (step S436). Specifically, the control unit 103 displays a display such as "Do you want to carry the gas container Bf to be carried into the cylinder cabinet 70?" On the screen of the display unit 104, thereby causing the gas to be carried into the cylinder cabinet 70. Ask the user whether to carry in the container Bf.

The user operates the operation unit 102 to input an answer to the question displayed on the screen of the display unit 104. When an instruction not to carry in the gas container Bf to be carried in is input to the cylinder cabinet 70, the operation terminal 100 ends the process. Here, it is assumed that the user has input an instruction to carry in the gas container Bf to be carried into the cylinder cabinet 70. In this case, the control unit 103 controls the communication unit 101 to transmit a carry-in instruction including an instruction to carry the gas container B into the cylinder cabinet 70 to the management device 40a (step S437). The communication unit 41 of the management device 40a receives the carry-in instruction transmitted from the operation terminal 100. After that, the communication unit 41 transmits the received carry-in instruction to the bomb transport trolley 2-2 (step S438).

The antenna 16d of the cylinder transport carriage 2-2 receives the carry-in instruction transmitted from the management device 40a. Since the received carry-in instruction is information related to carry-in, the communication control unit 241 outputs the carry-in instruction to the carry-in / out control unit 242. The carry-in / out control unit 242 controls the holding mechanism 21 and the slide drive mechanism 22 to carry the gas container Bf to be carried into the cylinder cabinet 70 (step S439). When the carry-in target gas container Bf is completed, the carry-in / out control unit 242 notifies the communication control unit 241 that the carry-in target gas container Bf has been carried in. The communication control unit 241 transmits the carry-in completion information indicating that the carry-in target gas container Bf has been carried in to the management device 40a (step S440).

The communication unit 41 of the management device 40a receives the carry-in completion information transmitted from the cylinder transport carriage 2-2. The communication unit 41 transmits the received carry-in completion information to the operation terminal 100 (step S441).
The communication unit 101 of the operation terminal 100 receives the carry-in completion information transmitted from the management device 40a. The control unit 103 inquires the user whether or not to end the work based on the carry-in completion information received by the communication unit 101 (step S442). Specifically, whether or not the control unit 103 ends the work by displaying a display such as "Do you want to return the cylinder transport carriage 2-2 to the accommodation position?"

For example, the cylinder cabinet 60 and the cylinder cabinet 70 automatically close the door when the cylinder carrier 2 receives a signal indicating that the door is closed. Such control is realized by a control box provided in the cylinder cabinet 70 and the cylinder cabinet 70.

(Third Embodiment)
The gas container B requires a certain period (delivery period) from the ordering to the delivery. Therefore, if an order is placed after the remaining amount of gas filled in the gas container B becomes less than the threshold value, it is assumed that the inventory may be insufficient until a new gas container B is delivered. Therefore, in the third embodiment, in addition to the above configuration, a configuration for performing appropriate inventory management based on the consumption tendency of the gas container B will be described. The basic system configuration is the same as that of the first embodiment or the second embodiment. The difference between the first embodiment and the second embodiment is that the configuration of the management device is different. Therefore, in the following description, only the differences will be described.

FIG. 20 is a schematic block diagram showing a functional configuration of the management device 40b according to the third embodiment. The management device 40b includes a CPU, a memory, an auxiliary storage device, and the like connected by a bus, and executes a control program. By executing the control program, the management device 40b functions as a device including a communication unit 41, an operation unit 42, a storage unit 43b, a display unit 44, and a control unit 45b. In addition, all or a part of each function of the management device 40b may be realized by using hardware such as ASIC, PLD and FPGA. Further, the control program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a flexible disk, a magneto-optical disk, a portable medium such as a ROM or a CD-ROM, or a storage device such as a hard disk built in a computer system. Further, the control program may be transmitted and received via a telecommunication line.

The storage unit 43b stores the container table 431, the management table 432, the gas utilization information 434, and the prediction model 435. The gas utilization information 434 is information indicating the remaining amount of each number of days for each gas container B of each gas type in use in the cylinder cabinet 70.
The prediction model 435 is a model learned to output an estimated date when the amount of gas filled in the gas container B is less than the threshold value based on the gas utilization information 434. The prediction model 435 is stored in the storage unit 43b for each gas type.

The control unit 45b controls the operation of the management device 40b. The control unit 45b determines whether or not the gas ordering conditions are satisfied based on the gas consumption forecast by the prediction model 435, the inventory information of the gas container B, and the delivery period of the gas container B, and orders the gas. When the conditions are satisfied, information prompting the order for the gas container B is output. The inventory information of the gas container B may be calculated based on the container table 431. For example, the control unit 45b may calculate the unused gas container B among the gas containers B registered in the container table 431 as the number of stocks of the gas container B. For example, the control unit 45b may determine that the gas container B stored in the cylinder bestker 60 among the gas containers B registered in the container table 431 is unused. The gas ordering condition is a condition for considering that the ordering of the gas container B is necessary. For example, the inventory of the gas container B on the date estimated by the gas consumption forecast (hereinafter referred to as "estimated date") is less than the threshold value. That is. In terms of operation, it is desirable that the gas container B can be delivered before the estimated date while satisfying the above conditions. The control unit 45b learns the prediction model 435 based on the gas utilization information 434.

FIG. 21 is a flowchart showing a flow of order processing performed by the management device 40b according to the third embodiment. The ordering process is a process of placing an order for the gas container B. The process of FIG. 21 is executed at a predetermined timing. For example, the process of FIG. 21 may be executed at a predetermined time, or may be executed at a timing instructed by the user.
The control unit 45b selects one gas type (step S501). For example, when instructed by the user, the control unit 45b selects the gas type selected by the user. When a plurality of gas types are selected by the user, the control unit 45b randomly selects one gas type. Further, when the gas is executed at a predetermined time, the control unit 45b randomly selects one gas type.

The control unit 45b acquires the gas utilization information 434 and the prediction model 435 corresponding to the selected gas type from the storage unit 43b. Then, the control unit 45b acquires the estimated date by inputting the acquired gas utilization information 434 into the prediction model 435 (step S502). The control unit 45b acquires inventory information of the gas container B corresponding to the selected gas type from the container table 431 (step S503). Further, the control unit 45b acquires the delivery date information of the gas container B corresponding to the selected gas type (step S504). The delivery date information of the gas container B corresponding to the gas type may be stored in advance by the management device 40b, or may be included in the essential information transmitted from the communication device 30.

The control unit 45b determines whether or not the gas ordering condition is satisfied based on the acquired gas consumption forecast, the inventory information of the gas container B, and the delivery period of the gas container B (step S505). When the gas ordering condition is satisfied (step S505-YES), the control unit 45b displays information prompting the ordering of the gas container B on the display unit 44 (step S506). At this time, the control unit 45b includes, as information for prompting the ordering of the gas container B, in addition to the necessity of ordering, information such as the number of stocks of the gas container B and how many days the stock quantity becomes less than the threshold value. May be displayed on the display unit 44. The control unit 45b determines whether or not it has been input that an order is required (step S507). When it is input that an order is required (step S507-YES), the control unit 45b orders the corresponding gas container B (step S508). The control unit 45b determines whether or not the end condition is satisfied (step S509). The end condition is a condition for terminating the order processing, for example, an instruction to end the order may be input from the user, or the gas order condition has been determined for all gas types. It may be that the gas ordering condition is determined a predetermined number of times.

When the end condition is satisfied (step S509-YES), the control unit 45b ends the order processing.
On the other hand, when the end condition is not satisfied (step S509-NO), the control unit 45b executes the processes after step S501.
When the gas ordering condition is not satisfied in the process of step S505 (step S505-NO), or when it is input that the order is not required in the process of step S507 (step S507-NO), the control unit 45b is the end condition. Is satisfied or not (step S509).

According to the gas container management system according to the third embodiment configured as described above, the same effect as that of the first embodiment or the second embodiment can be obtained.
Further, in the gas container management system according to the third embodiment, the gas consumption forecast and the inventory information of the gas container B are combined to encourage the ordering of the gas container B. As a result, it is possible to notify the manager or the like that it is necessary to place an order for the gas container B before the gas container B becomes insufficient. As described above, in the gas container management system according to the third embodiment, the gas container B can be easily managed.

(Modified example of the third embodiment)
The control unit 45b may be configured to display the consumption prediction result of the gas container B selected by the user on the display unit 44. When configured in this way, the control unit 45b uses the gas utilization information 434 corresponding to the gas container B selected by the user as the input of the prediction model 435.
This makes it possible to provide the user with the consumption prediction result of the specific gas container B.

The control unit 45b may be configured to automatically order the gas container B when the gas ordering condition is satisfied. In this case, the control unit 45b compares the stock quantity of the gas container B at the time when the gas ordering condition is satisfied with the predetermined stock quantity. Then, the control unit 45b automatically orders the gas containers B in the insufficient number with respect to the predetermined inventory quantity.

Get container information by.

A recording medium other than the electronic tag 90 may be arranged in the gas container B housed in the cylinder cabinet 60 and the cylinder cabinet 70. For example, the gas container B may be affixed with a label printed by converting the information transmitted from the management devices 40, 40a, 40b into code information (for example, a one-dimensional code or a two-dimensional code). When configured in this way, the gas container management system 1 may include a printing device capable of printing a label on which code information is printed, instead of the writing device 50. In this case, the reading device 61 of the cylinder cabinet 70 and the reading device 71 of the cylinder cabinet 70 are provided with a reading device capable of reading the code information printed on the label.

The writing device 50 may acquire specific information from the communication device 30. When configured in this way, the communication device 30 transmits the essential information and the specific information to the management devices 40, 40a, 40b, and also transmits the specific information to the writing device 50. In such a case, the specific information may be automatically generated by the communication device 30, or the information input by the user may be used as the specific information.
