Description

  The present invention relates to a gas cylinder management system. In particular, the present invention relates to a gas cylinder management system that manages the route of gas cylinders from initial delivery, delivery from a filling station to a consumer's house, and collection and disposal from the consumer's house.

  The liquefied petroleum gas (LP (Liquefied Petroleum) gas) used in ordinary households is mainly imported from the gas-producing countries (imported LP gas) and refined in the production process of petroleum products. It is divided into what is made (domestic production LP gas). Gas supply companies that supply LP gas are import bases for storing LP gas transported by tankers from gas-producing countries (for storage of imported LP gas), and oil refineries (refiners for domestically produced LP gas). Each of which is called a primary base.

  In addition to the primary base, the gas supply company has a secondary base that functions as a relay base for delivering LP gas nationwide. LP gas is loaded from a primary base onto a coastal ship or trailer and shipped to a secondary base. In addition, gas supply companies have filling stations in various locations where LP gas is filled. The LP gas that has been transported to the secondary base is transported to the gas filling station, and gas is filled into the gas cylinders. The

Furthermore, gas supply companies have facilities called depot stations in various places. A depot station is a facility for storing gas cylinders delivered from a filling station. Is delivered to a depot station, where it is transshipped to a small delivery vehicle.

  The gas cylinders filled at each filling station are delivered to consumers such as ordinary households, apartment houses, and offices (in some cases via a depot station) by the workers of the gas supplier. In addition, the worker replaces the empty gas cylinder installed in the consumer's home with a filled gas cylinder, and the empty gas cylinder is collected at the filling station (in some cases, via a depot station). Is done.

Japanese Patent Laying-Open No. 2015-207869

  The gas supply company assigns an identification number to each gas cylinder, and manages where the gas cylinder is currently installed in the computer system. For example, when a gas cylinder to which an identification number is assigned is installed in a consumer's house, the gas cylinder is managed as being installed in the consumer's house (by assigning an identification number to each consumer as well) ). Since gas cylinders are dangerous goods, management of such gas cylinders is also required by law.

  As described above, the location of the gas cylinder can be managed in a state where the gas cylinder is installed in the consumer's house. However, if the gas cylinder that is to be delivered from the filling station to the depot station, from the filling station to each consumer house, or from the depot station to each consumer house, is lost in the middle of the route, the lost gas cylinder The location may be unknown.

  In fact, gas cylinders loaded on trailers may be stolen during delivery (for example, on the route from the depot station to each consumer's house). With the current management system, The location of the gas cylinder cannot be ascertained. This is a problem that should be improved because the gas supplier has an obligation to handle gas cylinders safely.

  Patent Document 1 discloses a centralized management system for object information in which a central management center manages an installation storage location of a gas cylinder by monitoring an ID number of an information management unit provided with an ID number and integrated with the gas cylinder. Is disclosed.

  In the system according to Patent Document 1, the information management unit includes a GPS (Global Positioning System) sensor and a seismic intensity sensor. Regarding the management of the gas cylinder, the movement of the gas cylinder is detected by using GPS information obtained from the GPS sensor, PHS (Personal Handyphone System) base station information, or output information of the seismic intensity sensor.

  The system according to Patent Literature 1 manages a gas cylinder in a delivery route such as a route from a depot station to a consumer's house when delivering a gas cylinder filled with gas or collecting a gas cylinder in which gas is emptied. This is not the main purpose.

  When a gas cylinder is delivered or collected, the gas cylinder moves through a filling station, a depot station, or a consumer's house and a predetermined location (route). From such a background, it is sufficient to grasp only the gas cylinder that deviates from the predetermined place (route). Nevertheless, in the system according to Patent Document 1, the movement is always managed by installing an information management unit in each gas cylinder. This may detect an incorrect movement based on output information from the seismic intensity sensor, such as when detecting a movement of a gas cylinder.

  In addition, in the system according to Patent Document 1, it is necessary to install an information management unit in each gas cylinder. For a gas supply company storing a huge number, it is practical to install information communication units in all gas cylinders. Absent. In addition, the information communication unit itself needs a power source, and there is a problem of securing an appropriate power source.

  In addition, the gas cylinders are legally obligated to perform a pressure-resistant inspection periodically, and the removal of the information communication unit must be taken into consideration when performing the inspection and repainting the gas cylinder.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a gas cylinder that manages the movement path of each gas cylinder in the delivery / recovery path of the gas cylinder with a simple configuration and high accuracy. To provide a management system.

  In order to solve the above problems, a gas cylinder management system according to the present invention includes a server computer, a portable terminal, and a sensor gate, and is a system for managing a movement path when delivering a gas cylinder, wherein the portable terminal is A first input interface for receiving input of a worker ID corresponding to a worker delivering the gas cylinder, first state information for the gas cylinder, and first waypoint information corresponding to a waypoint where the gas cylinder is located The gas cylinder ID is acquired from a first bar code attached to the gas cylinder and encoded with the gas cylinder ID corresponding to the gas cylinder, and the acquired gas cylinder ID and the received worker ID are displayed. , Including the received first status information and the received first waypoint information, A portable terminal control unit that generates one gas cylinder state message; and a portable terminal communication unit that transmits the generated first gas cylinder state message to the server computer, wherein the sensor gate is located at the sensor gate.

The communication unit 21, the control unit 22, the main storage unit 23, and the auxiliary storage unit 24 have functions equivalent to the communication unit 11, the control unit 12, the main storage unit 13, and the auxiliary storage unit 14 of the gas cylinder management server 1.

  The display unit 25 executes the portable terminal execution program downloaded from the gas cylinder management server 1 so that an operator can input predetermined state change information such as when the gas cylinder 4 is filled with gas. It is a display which displays.

  The camera 26 photographs the two-dimensional barcode 4b attached to the gas cylinder 4. The gas cylinder ID is encoded in the two-dimensional barcode 4b, and the photographed two-dimensional barcode is decoded by the control unit 12, and the control unit 22 acquires the gas cylinder ID by this processing. The camera 26 may be built in the mobile terminal 2 or connected externally according to a data transfer standard such as USB (Universal Serial Bus).

  The sensor gate 3 includes a communication unit 31, a control unit 32, and a storage unit 33, which are coupled to each other. Further, an IC tag 4a and a two-dimensional barcode 4b are attached to the gas cylinder 4. The IC tag includes a communication unit 41, a control unit 42, and a storage unit 43, and these elements are coupled to each other.

  The communication unit 31 is an antenna that generates a radio wave or a magnetic field and communicates with the communication unit 41 of the gas cylinder 4 by an arbitrary short-range wireless method. The IC tag 4a is a passive tag, and the communication unit 41 (antenna) receives a radio wave or a magnetic field from the communication unit 31 and rectifies (in the case of an electric field) or resonates (in the case of a magnetic field) to generate electric power. The control unit 42 and the storage unit 43 operate.

  In the IC tag 4a, the gas cylinder ID is stored in the storage unit 33, and the communication unit 41 transmits the stored gas cylinder ID to the sensor gate 3 by radio waves or magnetic fields. When the communication unit 31 receives the gas cylinder ID from the IC tag 4a, the control unit 32 acquires the gas cylinder ID. The storage unit 33 stores a waypoint identification number (passage point ID) that identifies each filling station and depot station (hereinafter, “passage point”). Then, the communication unit 31 transmits the acquired gas cylinder ID and the waypoint ID stored in the storage unit 33 to the gas cylinder management server 1 via the network 5.

  Next, an example of the gas cylinder management data table 300 according to the embodiment of the present invention will be described with reference to FIG. The gas cylinder management data table 300 is a database table stored in the data storage unit 14a of the gas cylinder management server 1, and reads, adds, updates, and deletes each data record by using SQL (Structured Query Language). Do.

  The gas cylinder management data table 300 has a data record corresponding to each of all the gas cylinders 4 possessed by the gas supplier, and each data record includes data items “gas cylinder ID” and “consumer identification number (consumer ID)”. ”,“ Worker identification number (worker ID) ”,“ route place ”,“ state ”, and“ manufacturing date ”(or“ manufacturing date ”). In the data item “consumer ID”, the identification number assigned to each consumer is associated with the gas cylinder ID corresponding to the gas cylinder 4 when the gas cylinder 4 corresponding to the target data record is installed in the consumer house. Is set.

  In the data item “worker ID”, an identification number assigned to each worker who has performed such work at the time of delivery / collection of the gas cylinder 4 corresponding to the target data record is assigned to the gas cylinder 4. It is set in association with the corresponding gas cylinder ID.

  In the data item “route point”, a value indicating which filling station or depot station the gas cylinder 4 corresponding to the target data record has been set is set. For example, identification numbers are assigned to all the filling stations and depot stations that the gas supplier has (for example, “01: A filling station”, “02: B filling station”, and “11: a depot station”). Such). Then, “01: A filling station” is set at the timing when the gas cylinder 4 corresponding to the target data record is filled at the A filling station, and then “11: a deposition station” at the timing when it arrives at the a deposition station. Is set. That is, at each filling station and depot station, values indicating the latest filling station and depot station through which the gas cylinder 4 has passed are set by inputting information from the portable terminal by the worker or reading the gas cylinder ID by the sensor gate 3. The

  In the data item “state”, a value indicating the state of the gas cylinder 4 corresponding to the target data record is set. For example, “01: Fill” is set at the timing when the gas cylinder 4 is filled with gas, and “02: Ship” is set when the gas cylinder 4 is shipped from the filling station.

  In the data item “manufacturing date” (or “manufacturing date”), the date of manufacture of the target gas cylinder is set. It is to be noted that LP gas gas cylinders are required by law to discard a gas cylinder when a predetermined period (hereinafter referred to as “filling period”) has elapsed since the date of manufacture. The elapsed gas cylinder is discarded without being filled with gas.

  Each data record of the gas cylinder management data table 300 is newly added when it is delivered from the manufacturer of the target gas cylinder 4 to the gas supplier. That is, when each gas cylinder 4 is delivered, a gas cylinder ID is assigned (an IC tag 4a in which the gas cylinder ID is stored and encoded and a two-dimensional barcode 4b are attached).

  Next, with reference to the flowchart of FIG. 4, the process which the gas cylinder management system which concerns on embodiment of this invention performs is demonstrated. In the process shown in FIG. 4, the worker fills the gas cylinder 4 with gas at the A filling station, and passes through the a depot station (the gas cylinder 4 is shipped from the a depot station) until delivery to the consumer's home. An example will be described.

<Gas filling>
First, the control unit 22 of the mobile terminal 2 executes the mobile terminal execution program (downloaded from the gas cylinder management server 1) stored in the main storage unit 23 to thereby display an initial screen (not shown) displayed on the display unit 25. Is displayed. In this state, when the worker inputs his / her worker ID and password, the control unit 22 executes authentication processing of the input worker ID and password. If this authentication is successful, the gas cylinder state information input interface is displayed on the display unit 25 (step S401).

  FIG. 5 shows an example of the gas cylinder state information input interface 500. The gas cylinder state information input interface 500 is an input interface for selectively inputting the state (for example, filling, shipping, and recovery) of the gas cylinder 4 delivered and collected by the worker and the waypoint where the gas cylinder 4 is currently stored. is there. On the gas cylinder state information input interface 500, the target gas cylinder ID and consumer ID are input by using the camera 26 (by photographing a two-dimensional barcode).

  As shown in FIG. 5, the gas cylinder state information input interface 500 includes a state information input pull-down list 501, a waypoint input pull-down list 502, a gas cylinder ID reading button 503, and a consumer ID reading button 504.

  The state information input pull-down list 501 is a pull-down list for selecting the state of the gas cylinder 4. For example, when the gas cylinder 4 is filled with gas at the filling station, the gas cylinder 4 is in a filled state. “01: Fill” is selected.

  The waypoint input pull-down list 502 is a pull-down list for selecting a filling station and a depot station in which the gas cylinder 4 is currently stored (positioned). For example, the gas cylinder 4 is stored in the A filling station. In this case, “01: A filling station” is selected.

  The gas cylinder ID reading button 503 is used when reading a two-dimensional bar code attached to the gas cylinder 4, and when the operator depresses the gas cylinder ID reading button 503, the camera 26 is activated, and a photographing screen is displayed on the display unit 25. Is displayed. On this imaging screen, the controller 22 acquires the gas cylinder ID encoded in the two-dimensional barcode 4b by imaging the two-dimensional barcode 4b attached to the gas cylinder 4.

  The consumer ID reading button 504 is used when reading a two-dimensional bar code attached to a gas equipment device (not shown) such as a gas meter installed in a consumer's house, and an operator uses the consumer ID reading button 504. By pressing, the camera 26 is activated and a shooting screen is displayed on the display unit 25. The two-dimensional barcode attached to the gas equipment device is encoded with a consumer ID. On this photographing screen, the control unit 22 acquires the consumer ID encoded in the two-dimensional barcode by photographing the two-dimensional barcode attached to the gas equipment device.

  Returning to the description of FIG. 4, in step S <b> 402, since the gas cylinder 4 is in a state of being filled with gas at the A filling station, the worker selects “01: A filling station” in the status information input pull-down list 501, and the waypoint In the input pull-down list 502, “01: Fill” is selected. Then, the gas cylinder ID reading button 503 is pressed, and the camera 26 is used to photograph the two-dimensional barcode attached to the gas cylinder 4. Thus, the control unit 22 acquires the selected state and waypoint, and the gas cylinder ID encoded in the photographed two-dimensional code (step S402).

  Next, the control unit 22 generates a gas cylinder filling state information message including the worker ID acquired in step 401 (when executing the authentication process) in the state, waypoint, and gas cylinder ID acquired in step S402. To do. The generated gas cylinder filling state information message is transmitted to the gas cylinder management server 1 by the communication unit 11 (step S403).

  When the communication unit 11 of the gas cylinder management server 1 receives the gas cylinder filling state information message transmitted in step S403, the control unit 12 sets target data in the gas cylinder management data table 300 based on the received gas cylinder filling state information message. The record is updated (step S404). Specifically, the worker ID, state, and waypoint value included in the gas cylinder filling state information message are set in the corresponding data items of the target data record. At this stage, since the gas cylinder 4 is not installed in the consumer's home, the value of the data item “consumer ID” is not set, and the gas cylinder 4 and the consumer are not associated with each other.

As described above, when the worker fills the gas cylinder 4, the gas cylinder 4, the filling station filled with the gas cylinder 4, and the worker who filled the gas cylinder 4 are associated with each other. The gas cylinder management server 1 manages that the state is filled.

  The worker ID, state, waypoint, and gas cylinder ID acquired in step S402 are belts that fill the gas cylinder 4 instead of information input via the gas cylinder state information input interface 500 (that is, manual input by the worker). You may acquire by reading the IC tag 4a attached | subjected to the gas cylinder 4 with the sensor (not shown) installed in the conveyor vicinity.

  In the above system, for example, a gas conveyor is provided with a belt conveyor for filling the gas cylinder 4, and a sensor for reading the IC tag 4a attached to the gas cylinder 4 is installed in the vicinity of the belt conveyor. With such a configuration, when filling the gas, the worker can obtain the gas cylinder ID by placing the gas cylinder on the belt conveyor (the gas cylinder management server 1 automatically sets the state and the transit point). ). Since the sensor installed in the vicinity of the belt conveyor has the same configuration as the sensor gate 3 described above, detailed description thereof is omitted.

  Since the sensor that has read the IC tag 4a of the gas cylinder 4 placed on the belt conveyor can identify the gas cylinder 4, it is determined whether or not the filling period has elapsed from the date of manufacture. May be. In this case, the target gas cylinder 4 is not to be transmitted to the gas cylinder management server 1 as described above (that is, the target data record of the gas cylinder management data table 300 is not updated) and is to be discarded. A warning will be output.

<Gas cylinder shipment>
When the gas cylinder 4 is filled with gas, the gas cylinder 4 is loaded on the trailer (or truck), and when the trailer loaded with the gas cylinder 4 leaves the A filling station, it passes through the sensor gate 3 installed at the outlet. (The gas cylinder 4 is shipped from the A filling station). The trailer may be loaded with 100 or more gas cylinders 4. The control unit 32 of the sensor gate 3 reads the IC tag 4a attached to each of the plurality of stacked gas cylinders 4, and acquires each gas cylinder ID (step S405).

  FIG. 6 is a diagram illustrating an example of a state in which the trailer 6 loaded with a plurality of gas cylinders 4 passes through the sensor gate 3. As shown in FIG. 6, the sensor gate 3 has an arch shape formed by two support portions 3 a and a sensor portion 3 b that is orthogonal to the support portion 3 a and extends substantially horizontally. Instead of the shape described above, the sensor gate 3 may have an L-shape formed by a single support portion 3a and a sensor portion 3b that is orthogonal to the support portion 3a and extends substantially horizontally. Or it may have any other shape.

  Each of the plurality of gas cylinders 4 is installed vertically on the loading platform of the trailer 6 in the longitudinal direction. As shown in FIG. 7, an IC tag 4a is attached to the upper surface in the length direction of each gas cylinder 4 so that the reading surface faces upward.

  In this state, when the trailer 6 loaded with a plurality of gas cylinders 4 passes below the sensor unit 3b of the sensor gate 3, the sensor unit 3b reads all the IC tags 4a attached to the plurality of gas cylinders 4. The gas cylinder IDs of all the gas cylinders 4 are acquired.

  As shown in FIG. 6, the length X in the horizontal direction of the sensor portion 3b extending between the two support portions 3a is at least the length in the short direction of the loading platform with reference to the front or rear of the trailer 6. Y or more. That is, the radio wave or magnetic field emission surface of the sensor unit 3b is configured to face the reading surfaces of all the IC tags 4a. With such a configuration, the IC tags 4a of all the gas cylinders 4 loaded on the cargo bed are within the range of radio waves or magnetic fields transmitted from the sensor unit 3b (antenna). As a result, the sensor unit 3b All IC tags 4a can be read.

  The sensor unit 3b is not limited to the configuration extending in the horizontal direction as described above, and may be any configuration such as extending in the vertical direction. Even when the configuration other than that shown in FIG. 6 is adopted, it is necessary that at least the radio wave or magnetic field emission surface of the sensor unit 3b is configured to face the reading surfaces of all the IC tags 4a.

  Returning to the description of FIG. 4, in step S406, the control unit 32 of the sensor gate 3 includes a gas cylinder shipment state information message including all the gas cylinder IDs acquired in step S405 including the waypoint ID stored in the storage unit 33. Is generated. The generated gas cylinder shipment state information message is transmitted to the gas cylinder management server 1 by the communication unit 31 (step S406).

  When the communication unit 11 of the gas cylinder management server 1 receives the gas cylinder shipment status information message transmitted in step S406, the control unit 12 performs the target data of the gas cylinder management data table 300 based on the received gas cylinder shipment status information message. The record is updated (step S407). Specifically, the data item “route point” of the target data record is updated to a value corresponding to the value of the route point ID included in the gas cylinder shipment status information message (for example, “01: A filling station”). . The data item “state” is updated to, for example, “02: Shipment”. The value set in the data item “state” may be determined to be updated based on the value already set by the state machine, for example (for example, in the case of state “01: filling” The value to be updated is “02: Shipment”). At this stage, since the gas cylinder 4 is not installed in the consumer's home, the value of the data item “consumer ID” is not set, and the gas cylinder 4 and the consumer are not associated with each other.

<Gas cylinder storage>
When the gas cylinder 4 is shipped from the filling station A, when the trailer 6 loaded with the gas cylinder 4 enters the a depot station, it passes through the sensor gate 3 installed at the inlet (the gas cylinder 4 is a depot station). To be received). When passing, the control unit 32 of the sensor gate 3 reads the IC tag attached to each of the plurality of stacked gas cylinders 4 and acquires each gas cylinder ID (step S408). The details when the sensor gate 3 reads the IC tag at this time have been described in step S405 and will not be described.

  Next, the control unit 32 of the sensor gate 3 generates a gas cylinder warehousing state information message including all the gas cylinder IDs acquired in step S408 including the waypoint ID stored in the storage unit 33. The generated gas cylinder storage state information message is transmitted to the gas cylinder management server 1 by the communication unit 31 (step S409).

  When the communication unit 11 of the gas cylinder management server 1 receives the gas cylinder warehousing state information message transmitted in step S409, the control unit 12 selects the target data in the gas cylinder management data table 300 based on the received gas cylinder warehousing state information message. The record is updated (step S410). Specifically, the data item “route point” of the target data record is updated to a value corresponding to the value of the route point ID included in the gas cylinder warehousing state information message (for example, “11: a depot station”). . Further, the data item “state” is updated to, for example, “03: warehousing”. The value set in the data item “state” may be determined to be updated based on the value already set by, for example, the state machine (for example, in the case of state “02: shipment”, The value to be updated is “03: Receipt”). At this stage, since the gas cylinder 4 is not installed in the consumer's home, the value of the data item “consumer ID” is not set, and the gas cylinder 4 and the consumer are not associated with each other.

<Gas cylinder transshipment>
When the gas cylinders 4 are stored in the a-depot station, a predetermined number of gas cylinders 4 are transshipped to a small delivery vehicle. At this time, the worker uses the state information input pull-down list on the gas cylinder state information input interface (through authentication processing by inputting his / her worker ID and password) displayed on the display unit 25 of the portable terminal 2. The state of 501 is selected (for example, “04: transshipment”), and the waypoint of the waypoint input pull-down list 502 is selected (for example, “11: a depot station”). Further, the camera 26 is used to photograph the two-dimensional barcode 4b attached to the gas cylinder 4 to be transshipped.

  The control unit 22 of the portable terminal 2 acquires the selected state and waypoint, and the gas cylinder ID encoded in the photographed two-dimensional code (step S411).

  Next, the control unit 22 generates a gas cylinder transshipment state information message including the worker ID used in the authentication process in the state, waypoint, and gas cylinder ID. The generated gas cylinder transshipment state information message is transmitted to the gas cylinder management server 1 by the communication unit 11 (step S412).

  When the communication unit 11 of the gas cylinder management server 1 receives the gas cylinder transshipment state information message transmitted in step S412, the control unit 12 sets the target data in the gas cylinder management data table 300 based on the received gas cylinder transshipment state information message. The record is updated (step S413). Specifically, the gas cylinder ID, the worker ID, the state, and the waypoint value included in the gas cylinder transshipment state information message are set in the corresponding data items of the target data record. At this time, when the worker who delivers the target gas cylinder 4 is changed in the a depot station, the data item “worker ID” is updated with the changed worker ID. At this stage, since the gas cylinder 4 is not installed in the consumer's home, the value of the data item “consumer ID” is not set, and the gas cylinder 4 and the consumer are not associated with each other.

<Gas cylinder shipment>
When the gas cylinder 4 is reloaded into a small delivery vehicle, the small vehicle loaded with the gas cylinder 4 passes through the sensor gate 3 installed at the exit when leaving the a depot station (the gas cylinder 4 is shipped from the a depot station). ) At this time, a process of updating the data record of the gas cylinder management data table 300 when the gas cylinder 4 ships a deposition station is executed. This process is the same as steps S405 to S407, and details of the process are performed. (The data item “route point” in the target data record of the gas cylinder management data table 300 is updated to “11: a depot station” and the data item “status” is updated to “02: shipping”).

<Gas cylinder installation>
When the gas cylinder 4 is shipped from the a depot station, the gas cylinder 4 is installed in each consumer's house. When the worker installs the gas cylinder 4 at the consumer's home, the gas cylinder state information input interface displayed on the display unit 25 of the portable terminal 2 (through an authentication process by inputting his own worker ID and password) Then, the state of the state information input pull-down list 501 is selected (for example, “05: Installation”), and the waypoint of the waypoint input pull-down list 502 is selected (for example, “21: Consumer's house”). Further, the camera 26 is used to photograph the two-dimensional barcode 4b attached to the gas cylinder 4 to be transshipped. Further, the consumer ID reading button 504 is pressed, and the camera 26 is used to photograph the two-dimensional barcode attached to the gas equipment installed in the consumer's house. Thereby, the control unit 22 acquires the selected state and waypoint, and the gas cylinder ID and the consumer ID encoded in the photographed two-dimensional code (step S414).

  Next, the control unit 22 generates a gas cylinder installation state information message including the worker ID used in the authentication process in the state, waypoint, gas cylinder ID, and consumer ID. The generated gas cylinder installation state information message is transmitted to the gas cylinder management server 1 by the communication unit 11 (step S415).

  When the communication unit 11 of the gas cylinder management server 1 receives the gas cylinder installation state information message transmitted in step S415, the control unit 12 sets the target data in the gas cylinder management data table 300 based on the received gas cylinder installation state information message. The record is updated (step S416). Specifically, the gas cylinder ID, the worker ID, the consumer ID, the state, and the waypoint value included in the gas cylinder installation state information message are set in the corresponding data items of the target data record. At this stage, since the gas cylinder 4 is installed in the consumer's home, the value of the data item “consumer ID” is set as the consumer ID corresponding to the consumer in which the gas cylinder 4 is installed. Are associated with consumers.

  As described above, each of the gas cylinders 4 is filled at the filling station, and is stored / shipped at / from each waypoint, and its state is managed at each timing when installed at the consumer's home. In addition, the latest waypoint through which each gas cylinder 4 passes is managed in association with the worker ID. With such a configuration, for example, when the gas cylinder 4 is lost (for example, while being shipped from the A filling station and entering the a depot station), the data record of the gas cylinder management data table 300 corresponding to the gas cylinder 4 is The state remains “02: Delivery” and the waypoint remains “01: A filling station”. Therefore, since another gas cylinder has been stored in the a depot station along the same route, it is specified that the lost gas cylinder 4 has been lost while being stored in the a depot station after being shipped from the A filling station. be able to.

  Further, the embodiment described above can be realized only by attaching the IC tag 4 a to each gas cylinder 4, and the present invention can be implemented easily and easily as compared with the invention according to the cited document 1.

  Furthermore, since the gas cylinder ID is read by reading the IC tag 4a through the short-range wireless communication and photographing the two-dimensional barcode 4b with the camera 26, the output information from the GPS and the seismic intensity sensor is used. Compared with the invention according to the cited document 1, the location of the gas cylinder 4 can be grasped with higher accuracy.

  In addition, only when the state of the gas cylinder 4 is changed, the gas cylinder ID is read and communication is performed between the gas cylinder management server 1, the portable terminal 2 and the sensor gate 3. Unnecessary communication does not occur, and the location of the gas cylinder 4 can be managed efficiently.

  In the present embodiment, the example of the filling and unloading of the gas cylinder 4 at the A filling station, the loading / reloading / shipping of the gas cylinder 4 at the a depot station, and the installation state of the gas cylinder 4 at the consumer's house have been described. Such state changes and travel paths are merely exemplary. For example, when the gas cylinder 4 is delivered to the filling station in the state of an empty container, or when the gas cylinder 4 is subjected to a pressure resistance test, the waypoint ID corresponding to the delivered waypoint / the waypoint where the pressure resistance test was performed is provided. The target data record of the gas cylinder management data table may be added or updated with the gas cylinder ID corresponding to the target gas cylinder 4. Further, in gas cylinder delivery, the gas cylinder 4 may be delivered via a plurality of depot stations, or the gas cylinder 4 may be delivered directly from the filling station to the consumer's house.

  As described above, the description of the gas cylinder management system according to the present embodiment has been described in detail, but the specific data structure such as the gas cylinder management data table 300 described in the embodiment is merely an example, and claims are made. Changes may be made without departing from the matters to be performed.

  Further, the input items shown by the gas cylinder state information input interface 500 are merely exemplary, and may include other data items. Furthermore, the order of the processing described in FIG. 4 is merely an example, the order may be changed, and the processing of the position portion may be added / omitted.

  In addition, the two-dimensional barcode 4b attached to the gas cylinder 4 and the two-dimensional barcode attached to the gas equipment may be one-dimensional barcodes. In this case, the gas cylinder is added to the one-dimensional barcode. The ID and consumer ID are encoded.
