Description

  The present invention relates to a gas management system and a gas supply mode change acceptance method.

  Conventionally, LP gas is divided into imports from gas producing countries and domestic production by-produced in the production process of petroleum products. The import base for storing LP gas transported by tankers from oil-producing countries and the oil refining base are called primary bases. LP gas is loaded into coastal ships and tanker trucks from the primary bases, either on the coast or inland. Shipped to a secondary base, which is a relay base for transporting certain LP gas. Next, the LP gas that has been transported to the secondary base is transported to LP gas filling stations (delivery bases) at various locations and filled into gas cylinders at the delivery bases. The gas cylinders filled at each delivery base are delivered to consumers such as ordinary households, apartment houses, and offices by delivery personnel. This is a supply method using a gas cylinder. Another supply method is a gas bulk supply method. This is a method of directly replenishing a gas bulk installed at a customer site with a tank truck. In the present specification, the gas cylinder and the gas bulk may be collectively referred to as a “gas container”.

  On the other hand, LP gas supplied by these methods may lead to pollution such as gas leakage and explosion. For this reason, Japan has established laws with the main objectives of ensuring the safety of pollution, pollution prevention, and the appropriateness of LP gas transactions, and conducting periodic surveys of gas supply facilities and consumption equipment for gas utilities. Mandatory. The supply facility refers to the gas container to the exit of the gas meter, and it is obliged to conduct periodic surveys under the responsibility of the gas company. The consumption equipment refers to the gas equipment (for example, gas stove and water heater) from the outlet of the gas meter. This is the responsibility of the consumer, but as with the supply equipment, regular surveys by gas companies Is required.

  The laws that require periodic surveys are the “Law Concerning the Securing of Liquefied Petroleum Gas and the Optimization of Transactions” (hereinafter referred to as the “Liquid Stone Law”) and the “Gas Business Law” (hereinafter referred to as the “Gas Law”). ) And two types, which are distinguished by the supply form. In the liquid stone method, LP gas is supplied directly to customers (for example, “general supply”) such as delivering cylinders to customers, and a simple gas generator, also called a gas workpiece, is installed. In addition, a mode is defined in which the gas generated by vaporizing LP gas is supplied to a plurality of consumers through a conduit. However, in the liquid stone method, it is applied to a scale where there are less than 70 suppliers, that is, customers. If this is more than 70 units, the Gas Business Law will apply. In this way, the equipment does not change, but the applicable laws differ depending on the supply scale, distinguishing each supply type, the liquid gas method is “concentrated gas (supply)”, the gas method is “simple gas” (Supply) ”.

  By the way, the consumer can change the gas supply mode as described above. When a customer changes the gas supply mode, the required law is changed (from the gas law to the liquid stone method or vice versa), and the supply or consumption equipment installed in the customer's home until now is changed. It may be necessary to collect and install new equipment in the changed supply form. In addition, since the gas supply form is different, the charge system is also different, and when accepting the change, the payment of the gas charge in the charge system before the change is settled and the gas charge of the customer in the charge system after the change is paid Management is required.

  Here, the conventional process in the case of changing the gas supply form of the consumer in a gas company is demonstrated below. First, the salesperson of the gas company receives a document in which the details of the change in the gas supply form are described by the customer by mail (step 1). This document describes at least the changed gas supply form and the scheduled date of change. Next, the security company's security officer visits the customer's house on the scheduled date of change described in the above document and confirms the amount of gas used at the time of change (step 2). The amount of gas used is confirmed by referring to the guideline value of the gas meter installed at the customer's house. Next, the security officer collects unnecessary equipment in the gas supply form after the change among the supply equipment and / or consumption equipment used in the gas supply form before the change (step 3). By this work, the gas is closed in the gas supply form before the change, and the gas is opened in the new gas supply form. Next, the security staff installs supply facilities and / or consumption facilities necessary for the changed gas supply form (step 4). In addition, the supply equipment and / or consumption equipment used before and after the change is replaced and / or investigated for equipment that needs to be replaced or surveyed, and the equipment that needs to be replaced is replaced (step 5). For equipment that needs to be investigated or replaced, a predetermined period is set for each equipment, and the security officer judges based on the installation time of the equipment and the most recent survey date. For example, a gas meter has a replacement deadline for each device, and the presence or absence of replacement work is determined based on whether or not the replacement deadline has passed. Next, the security officer performs a gas opening operation in a new gas supply form (step 6). At this time, the gas can be supplied in a new gas supply form. Next, the security officer returns to the sales office of the gas company in charge and reports the above gas usage to the sales staff, and the sales staff confirms the gas usage and the unit price of the gas charge corresponding to the gas supply form before the change. Based on the above, the gas usage fee in the gas supply form before the change is calculated (step 7). The unit price of the gas fee is determined according to the gas supply form. Next, the sales staff inputs the calculated gas charge into the gas management system (step 8), and settles the gas use charge in the contract in the gas supply form before the change of the consumer. Here, the adjustment of the gas usage fee in the contract in the gas supply form before the change is to register the adjusted amount in the gas management system, and when the next gas fee is charged (when the next gas fee is charged, (The gas usage fee is calculated based on the unit price in the contract in the gas supply configuration after the change), and the adjustment amount is added, and the gas usage fee in the contract in the gas supply configuration after the change and the above adjustment amount are added up Means being charged. Next, the sales staff inputs the changed gas supply form to the gas management system, and updates the gas supply form information associated with the customer (step 9). Finally, the sales staff issues a predetermined document or notice corresponding to the law corresponding to the changed gas supply form, and mails the document to the customer (step 10).

  Under such a mechanism, a system for improving the collection of gas charges has been proposed (see Patent Document 1).

JP 2008-117247 A

  As disclosed in Patent Document 1, although a system for improving the collection efficiency of the gas charge has existed conventionally, reception of a request for changing the gas supply form, adjustment of the gas charge in the gas supply form before the change, and change There has been no system that collectively performs payment management of gas charges in later gas supply forms, changes in supply equipment and consumption equipment information to be managed, security work management, and issuance of predetermined documents.

  Therefore, in the past, when accepting a change in the gas supply form of a consumer, manual calculation such as calculating a gas charge in the gas supply form before the change or mailing a predetermined document in accordance with the law. There were many situations that depended on work, and the burden on the workers was excessive. Further, mistakes due to manual work (for example, calculation error of gas charges) often occurred. In addition, there was a time difference between the plugging and unplugging work at the customer's house and the change registration work for the gas supply system to the gas management system, which could cause inconsistencies due to delays in the registration work. It was.

  Therefore, in view of such circumstances, the object of the present invention is to accept the change request, adjust the gas charge in the gas supply form before the change, and supply the gas after the change when the gas supply form is changed. Gas that can perform payment management of gas charges in the form, change of supply equipment and consumption equipment information to be managed, management of equipment replacement work and security investigation work, and issuance of predetermined documents in a lump The object is to provide a management system and a gas supply mode change acceptance method.

  In order to solve the above-described problems, a gas management system according to the present invention is a computer system that is connected to one or a plurality of communication terminals via a network and receives a gas supply mode change request from a consumer who receives the gas supply. Display means for displaying on the display unit of the one or more communication terminals to generate an input interface screen, wherein the input interface screen is a first unit that receives an input of a customer ID for identifying information about the customer. Display means including: a second screen that accepts an input of a classification of the gas supply form after the change of the consumer; and a third screen that accepts an input of an indicator indicating the gas usage of the consumer; The customer ID input on the first screen, the changed gas supply mode classification input on the second screen, and the third screen An input means for receiving from the one or more communication terminals, a first database for storing information relating to the consumer, and a second database for storing information relating to the unit price of gas charges The gas supply mode change of the consumer based on the third database for storing information on the payment status of the gas charge of the consumer, the received indicator, the first database, and the second database A gas charge calculation means for calculating a gas charge in the previous charge system, an unpaid amount calculation means for calculating an unpaid amount before the gas supply mode change of the consumer based on the third database, and the calculated gas A first updating means for updating the third database based on the charge and the calculated unpaid amount, and the received change Characterized in that it comprises a second updating means for updating the first database based of the classification of the gas supply form.

  According to the gas management system according to the present invention, communication for receiving a change request that has been performed manually in the past, for adjusting the gas charge in the charge system before the change, and for managing the payment of the gas charge in the charge system after the change is performed. By simply inputting the customer ID, the gas supply form classification after the change of the customer, and the indicator indicating the gas usage amount of the consumer from the terminal, the gas charge in the charge system before the change is calculated, and before the change Calculate the unpaid amount of the customer, update the information about the customer's payment amount based on the gas fee and unpaid amount in the previous fee structure, and update the customer information based on the changed gas supply type classification Therefore, it is possible to automate all the operations that have been performed manually.

  Hereinafter, a gas management system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a diagram showing a network configuration according to an embodiment of the present invention. In FIG. 1, for example, a gas management server 101 installed in a data center or the like is connected to a plurality of mobile terminals 103a, 103b,. ")"). A mobile terminal is carried by a person who performs security work such as each security worker. Further, the mobile terminal 103 can read the two-dimensional code assigned to the consumption facility 104 and the supply facility 105. The mobile terminal 103 is preinstalled with a two-dimensional code reading application and a menu display application. For example, in one embodiment, a two-dimensional code reading application displays a two-dimensional code reading screen when activated, and when the two-dimensional code of a consumption facility or a supply facility is successfully read, the read two-dimensional code data is gas-managed. This is transmitted to the server 101. The menu display application downloads customer data created by the gas management server 101, displays the downloaded data on the screen, and checks the input data when the security officer performs input according to the menu display, Input data is transmitted to the management server 101.

  The consumption facility 104 and the supply facility 105 are each affixed with a two-dimensional code label in which data for identifying each customer data is embedded.

  When the two-dimensional code attached to the consumption facility 104 or the supply facility 105 is read by the mobile terminal 103, the two-dimensional code reading application of the mobile terminal 103 transmits the read two-dimensional code data to the gas management server 101. .

  When the gas management server 101 receives the two-dimensional code data, the gas management server 101 acquires a record from the customer data storage unit based on the two-dimensional code data, creates customer data, and transmits it to the mobile terminal 103. The mobile terminal 103 receives customer data and displays it on the display screen. Next, when a gas supply mode change request is input via the input device of the mobile terminal 103, the menu display application checks the input data and then transmits the input data to the gas management server 101.

  The gas management server 101 receives the input data and stores it in the temporary storage area.

  Next, the configuration of the above-described gas management system will be described in detail with reference to the block diagram of FIG. The gas management server 101 includes a control unit 201, a main storage unit 203, an auxiliary storage unit 204, an input unit 205, an output unit 206, a communication control unit 207, and a database 208, and these elements are connected via a system bus 202. Is done.

  The control unit 201 is also called a central processing unit (CPU), performs control of each of the above-described constituent elements and data calculation, and reads various programs stored in the auxiliary storage unit 204 to the main storage unit 203 and executes them. To do. The main storage unit 203 is also called a main memory, and stores input data received by the gas management server 101, computer-executable instructions, data after arithmetic processing by the instructions, and the like.

  The auxiliary storage unit 204 is a storage device typified by a hard disk (HDD) and is used when data and programs are stored for a long period of time. Since the main storage unit 203 has a relatively smaller storage capacity than the auxiliary storage unit 204, it is used for temporary data storage, arithmetic processing, and the like, whereas the auxiliary storage unit 204 stores necessary data and information. Used for long-term storage and storage. That is, when the control unit 201 executes a program to perform data calculation, the necessary data or program is read from the auxiliary storage unit 204 to the main storage unit 203, and the calculation result data is stored and stored for a long time. In this case, the control unit 201 writes the calculation result data in the auxiliary storage unit 204. The database 208 includes data tables of a customer data storage unit, a gas unit price data storage unit, a payment data storage unit, and an equipment data storage unit, which will be described later.

  The mobile terminal 103 connected via the network 102 includes a communication control unit 211, a display unit 212, an input unit 213, and a control unit 214 connected via a system bus 215, and gas is transmitted via the communication control unit 211. Information is exchanged with the management server 101.

  An input interface screen provided by the gas management system is displayed on the display unit 212, and the security officer inputs a request for changing the gas supply form via the input interface screen. The input data is transmitted to the gas management server 101 and temporarily stored in the main storage unit 203 or the auxiliary storage unit 204.

  The input unit 213 receives the two-dimensional code read from the input interface screen displayed on the display unit 212. The received two-dimensional code data is converted into digital data and transmitted to the gas management server 101 via the communication control unit 211.

  The control unit 214 performs processing for switching the input interface screen displayed on the display unit 212 based on the data transmitted from the gas management server 101.

  FIG. 3 is a diagram showing an example of a customer data storage unit of the gas management system according to the present invention. The customer data storage unit stores information related to a customer who receives a gas supply service from a gas company. In one embodiment, as shown in FIG. 3, the customer data storage unit includes a “customer code”, “name”, “address”, and customer equipment (consumed equipment) for identifying a customer according to the liquid stone method. “Customer category” indicating whether the product is related to the Gas Act or “Gas Heat” of the supplied gas, “Opening status” of the gas at the customer's house, “Meter code” identifying the gas meter installed at the customer's house ”, A“ supply equipment code ”for identifying the installed supply equipment, and a“ consumption equipment code ”for identifying the installed consumption equipment. “Customer classification” is “0” when the customer equipment (consumption equipment) is related to the liquid stone method, that is, the general supply type equipment or the concentrated gas supply type consumption equipment. “1” is stored in the case of the related equipment, that is, the consumption equipment of the simple gas supply form. As will be described later, the gas charge is determined for each “customer category” and “heat quantity”, and these pieces of information are used to specify the unit price of the gas charge of the consumer. “Opening status” is used to determine whether or not to settle the gas fee, which will be described later, and is a situation where there is no facility for a new customer to enter and supply gas. There are “no occupancy: 0”, “opening: 1” in which gas is normally supplied, and “capping: 2” in which gas supply is stopped for some reason. The above-mentioned “new occupancy” and “clogging” indicate a situation in which no gas is supplied to the customer's house. “Meter code” identifies a gas meter installed at a customer's house. Based on this code, by referring to data in an equipment data storage unit to be described later, the gas meter installed at the customer's house can be replaced. The necessity can be determined. “Supplied equipment code” and “consumed equipment code” identify equipment installed at the customer's house, and by referring to the data in the equipment data storage unit based on that code, it is possible to It is possible to grasp the necessary replacement time and survey date. In the present embodiment, the customer data storage unit includes information related to the “customer” that is the partner of the gas supply contract (customer classification, etc.) and information related to the “customer” such as name and address. However, for example, a customer data storage unit storing a “customer code”, “name”, “address” and the like for identifying a customer is provided separately, and the customer data storage unit is linked. Good.

  FIG. 4 is a diagram showing an example of the gas unit price data storage unit of the gas management system according to the present invention. The gas unit price data storage unit stores information related to the unit price of the gas usage fee. In one embodiment, as shown in FIG. 4, the gas unit price data storage unit is composed of “customer category”, “heat quantity”, “basic charge”, and “unit price”. In the present embodiment, the basic charge and the unit price are determined for each “customer category” and “heat quantity”, and a record exists in that unit. However, the unit for determining the basic charge and the unit price is not limited to the elements described above.

  FIG. 5 is a diagram showing an example of a payment data storage unit of the gas management system according to the present invention. The payment data storage unit stores information indicating the payment status of the gas usage fee paid by the customer every year or every month. In one embodiment, as shown in FIG. 5, the payment data storage unit is composed of “customer code”, “year / month”, “gas usage fee”, and “paid flag” indicating whether or not the gas fee has already been paid. Is done. In this embodiment, for example, a customer whose customer code is “00000001” pays a monthly gas usage fee by monthly payment, and a record indicating whether or not the monthly gas usage fee and the fee have been paid is created. . When the “paid flag” is “1”, it indicates that the payment has already been completed, and when it is “0”, it indicates that the payment has not been made. That is, in FIG. 5, the customer whose customer code is “00000001” has already paid the gas charge from June 2012 to December 2012, and has not paid for January 2013. This data is used when calculating the billed amount of the gas charge of the consumer. Taking the consumer code “00000001” as an example, the gas charge for January 2013 is unpaid. When the amount of gas charge for February 2013 is confirmed, a new record is created in the payment data storage unit (“year” is February 2013), and the unpaid amount of 14,350 yen is It is added to the gas usage fee for the month (the unpaid amount is added to the determined gas fee for February, and the amount added to the “gas usage fee” of the new record is set).

  FIG. 6 is a diagram illustrating an example of updating the above-described payment data storage unit, details of which will be described later.

  FIG. 7 is a diagram showing an example of the equipment data storage unit of the gas management system according to the present invention. The equipment data storage unit stores information related to supply equipment and consumption equipment. In one embodiment, as shown in FIG. 7, the equipment data storage unit “equipment code” for identifying the supply equipment and the consumption equipment, “equipment name”, and “equipment classification” indicating whether the equipment is the supply equipment or the consumption equipment. `` Management category '' indicating whether it is in the gas company's facility or at the customer's house, etc., `` Installation date '', `` Last security work date '' of the relevant equipment, “Re-investigation flag” indicating whether or not a survey is necessary, “replacement years” indicating the number of years that need to be replaced, and “security survey” indicating the number of years that the next security survey is necessary based on the latest security work date It consists of “interval”. When the equipment category is “0”, it is a supply equipment, and when it is “1”, it is a consumption equipment. When the management category is “0”, the equipment is present at the gas company's facility, when “1” is present, the equipment is present at the customer's house, and when “2”, the corresponding equipment is discarded. . The management category has an initial value of “0” and is updated to “1” when the corresponding equipment is installed in the customer's house, and returns to “0” again when collected from the customer's house to the gas company's facility. When it is discarded after the period, it is updated to “2”. The “installation date” is set to the date when the corresponding equipment is installed at the customer's house. The “date of most recent security work” is set to the date of the work date every time a security survey is conducted. “Replacement years” indicates the number of years required for replacement, which is determined for each facility. By adding this number of years to the “installation date” described above, it is possible to determine whether the facility needs to be replaced. The “security inspection interval” indicates the number of years that the next security work is required, calculated from the most recent security work date determined for each facility. By adding this number of years to the “most recent security work day” described above, It is possible to determine whether or not the safety work for the corresponding equipment is necessary.

  Next, with reference to the flowchart of FIG. 8, the gas supply form change acceptance process executed by the gas management server 101 according to the embodiment of the present invention will be described.

  The gas company salesperson receives a notification from the customer that the gas supply mode will be changed, and the security staff visits the customer's home to accept the change in the gas supply mode and to settle the gas fee under the old charge system. Suppose you are visiting. The security officer selects the gas supply mode change acceptance menu from the input interface screen, which is the initial menu screen displayed on the display unit 212 of the mobile terminal 103, thereby starting this processing.

  First, in step 801, an input interface screen for reading a two-dimensional code is displayed on the display unit 212 of the mobile terminal 103. It should be understood that this may be a state where a two-dimensional code can be read and can be replaced by various applications. Next, the security officer uses the mobile terminal 103 to read the two-dimensional code attached to the consumption equipment 104 or the supply equipment 105 before the change installed in the customer's house, and the two-dimensional code is used to control the mobile terminal 103. It is converted into digital data by the unit 214, transmitted to the gas management server 101, and received by the input unit 205 (step 801). Here, the received two-dimensional data code indicates a customer code for identifying the customer.

  Next, the control unit 201 acquires a record from the customer data storage unit using the two-dimensional code data received in step 801 as a key (step 802).

  Next, the control unit 201 transmits the customer data acquired in step 802 to the mobile terminal 103 via the communication control unit 207 (step 803). The customer data transmitted from the gas management server 101 is displayed on the display unit 212 of the mobile terminal 103, and the security officer confirms the customer classification and the heat quantity of the relevant customer at that time (before change).

  Next, the security officer who has completed the above confirmation presses the “subsequent execution” (not shown) button displayed on the display unit 212 to input the gas supply mode change to the display unit 212 of the mobile terminal 103. An input interface screen for accepting is displayed. As shown in FIG. 9, the input interface screen displayed on the display unit 212 of the mobile terminal 105 may be configured to accept selection of a consumer category and a heat amount displayed in a pull-down format. The security officer selects the customer category and heat quantity to be changed from the pull-down menu displayed on the display unit 212 of the mobile terminal 105, and transmits the changed customer category and heat quantity determined by the selection to the gas management server 101. The input unit 205 receives them (step 804). In addition, the item input when changing a gas supply form is not limited to the content mentioned above, The thing including other elements may be combined.

  Next, the control part 201 determines the change classification of a gas supply form based on the received consumer classification and heat amount after a change (step 805). Here, determining the change type of the gas supply mode means that the customer category is changed from the liquid stone method to the gas method, the customer category is changed from the gas method to the liquid method, etc. The change type is determined because the change type is required to control the output of a predetermined document defined by law that is output when the gas is opened as described later. As the determination operation, for example, a change type flag is provided inside the gas management server 101. When the customer category is changed from the liquid stone method to the gas method, the change type flag is set to “0”, and the customer category is When the gas method is changed to the liquid stone method, the change type flag is set to “1”, and when the calorific value is changed from LP gas to city gas, the change type flag is set to “2”. You may comprise. If the received change request is a change in customer category (eg, “Liquid stone method” to “Gas business method”) or a change in calorific value, the change request is the above content via the communication control unit 207 To the mobile terminal 103, the mobile terminal 103 displays a message to that effect on the input interface screen on the display unit 212, and a request for changing the gas supply form is accepted by a confirmation input of the change by the security staff.

  Next, the control unit 201 determines the gas opening status of the consumer at that time (before change) based on the “opening status” included in the record of the customer data storage unit acquired in step 802. (Step 806). Here, the gas opening state of the consumer is determined, for example, when the opening state of the consumer is “new unoccupied” or “capped”, the consumer is currently supplied with gas. This is because the use of gas at that time is not assumed and it is not necessary to perform the subsequent gas charge settlement process.

  If the opening state of the corresponding consumer is “open” in the determination process, the process proceeds to the subsequent step (gas charge settlement process), and if not, the process proceeds to step 814 (step 807).

  Next, when it is determined in step 807 that the opening state is “opening”, an input for accepting an input of a gas usage indicator displayed on a gas meter installed in a consumer's house on the display unit 212 of the mobile terminal 103. The interface screen is displayed. The security officer inputs a gas usage indicator from the input interface screen displayed on the display unit 212 of the mobile terminal 105, the indicator is transmitted to the gas management server 101, and the input unit 205 receives it (step 808).

  Next, the control unit 201 acquires a record in the gas unit price data storage unit using the customer category and the amount of heat included in the record in the customer data storage unit acquired in Step 802 as keys (Step 809).

  Next, the control unit 201 calculates the gas rate before the change based on the basic rate and unit price included in the record of the gas unit price data storage unit acquired in step 809 and the gas usage amount indicator received in step 808 ( Step 810). Thus, since the record of the customer data storage unit can be acquired from the two-dimensional code read from the mobile terminal 103 and the record of the gas unit price data storage unit can be acquired based on the record, the security officer can By simply reading the two-dimensional code from the input and inputting the gas usage indicator, the gas usage fee before the change can be accurately calculated without manual calculation as in the conventional process.

  Next, the control unit 201 uses the two-dimensional code data as a key to acquire a record having a “paid flag” of “0” from the payment data storage unit (step 811). Here, the reason why the record is acquired from the payment data storage unit is that the gas fee including the unpaid portion in the fee system before the gas supply mode change is settled. As shown in FIG. 5, when a customer with a customer code “00000001” is taken as an example, a record whose “paid flag” is “0” is a record whose “year” is January 2013. Records will be obtained.

  Next, the control unit 201 adds a new record to the payment data storage unit (step 812). For the record to be added, the corresponding customer code is set in the “customer code”, and the year and month in which the corresponding process is performed (for example, using the time stamp of the gas management server 101). The gas charge calculated in step 810 is set in “gas charge”, and “0” is set in “paid flag”. If an unpaid data record can be acquired from the payment data storage unit in step 811, the amount of “gas usage fee” included in the unpaid data record is added to the “gas usage fee” of the newly added record, and unpaid The “paid flag” of the data record is updated to “1” (step 813). This example is shown in FIGS. 5 and 6, as described above, in FIG. 5, a record with the customer code “00000001” and “year” as January 2013 is acquired as an unpaid data record. It is assumed that the processing is performed in February 2013. Although not shown, if the pre-change gas usage fee calculated by the control unit 201 in step 810 is “7,120”, the gas fee of the unpaid data record in January 2013 is “14,350”. A gas usage fee of “21,470” is newly added as a payment data record for February 2013. Then, the “paid flag” in the January 2013 record is updated to “1”. In this way, since a new record regarding the gas fee before change including the unpaid portion is added to the payment data storage unit, the gas fee in the gas supply form before change can be managed as unpaid, and at the time of the next payment The amount of the gas charge is also billed at the same time, so that the gas supply form is not input to the gas management system without inputting the adjustment amount of the gas charge in the gas supply form before the change manually calculated as in the conventional process. By simply inputting the request for change and the gas usage amount indicator, it is possible to settle the gas charge in the gas supply form before the change and to manage the payment of the gas charge in the gas supply form after the change.

  Next, the control unit 201 acquires a record in the customer data storage unit based on the change type determined in step 805, using the two-dimensional code data received in step 801 as a key, and the demand included in the record The customer data storage unit is updated by changing the house classification and / or the amount of heat (step 814). For example, when the change type is determined to be a change from “liquid stone method” to “gas business method”, the customer category is changed from “0” to “1”. At this point, the gas management system has accepted the gas supply form of the relevant customer. At this point, the supply equipment and / or consumption equipment used before the change by the security officer is collected. Then, the gas supply plugging work before the change is performed.

  Next, the control unit 201 acquires a record from the facility data storage unit using the “meter code” included in the record of the customer data storage unit acquired in step 802 as a key (step 815). The “meter code” included in the customer data storage unit corresponds to the “equipment code” included in the facility data storage unit.

  Next, the control unit 201 determines whether or not the gas meter needs to be replaced based on the “installation date” and the “year of replacement” included in the record of the equipment data storage unit acquired in step 815 ( Step 816). Such determination will be described with reference to FIG. Assume that a customer having a gas meter with an equipment code (meter code) “A0000001” changed the gas supply form in December 2012. Since the installation date of the gas meter with the equipment code “A0000001” is November 2, 2002 and the replacement year is 10 years, it is determined that the gas meter needs to be replaced in this step. In the present embodiment, the above-described replacement years and security inspection intervals are set for each facility, but another table may be provided in which these pieces of information are determined for each facility category.

  As a result of the determination process, if it is determined that the gas meter needs to be replaced, the control unit 201 displays an indicator indicating that the corresponding equipment code or name and the replacement work are necessary, and a communication control unit 207. Is transmitted to the mobile terminal 103 (step 817). Even when it is determined that the gas meter replacement work is not necessary, a screen on the display unit 212 of the mobile terminal 103 to be described later transmits a signal for transition of a “multifunction transition menu” to the mobile terminal 103.

  Next, in step 818, in response to the reception of the equipment code or equipment name and indicator, or the signal for transition, an input interface screen that becomes a “multi-function transition menu” on the display unit 212 of the mobile terminal 103 Is displayed. Here, opening work by security personnel is necessary following the above-described closing work, but the input interface screen, as shown in FIG. 10, is a gas meter exchange and security investigation work for opening the opening work. This is a screen for entering presence / absence. For example, when a security investigation is performed based on the security officer's own judgment, a “security investigation” menu button shown in FIG. 10 is pressed to transition to the “security investigation” input screen.

  Referring to FIG. 10, the menu buttons other than “Replace Gas Meter” are shaded to indicate that they are inactive buttons (does not accept input), which is installed at the customer's home in step 816. Since it is determined that the gas meter needs to be replaced, it is necessary to replace the gas meter first, and the control is performed to prompt the input of the security staff in preference to the other menu buttons. In this control, the gas management server 101 transmits an indicator indicating that the customer's meter needs to be replaced in step 817, and the mobile terminal 103 displays the input interface in response to the reception of the indicator. I have control. In this embodiment, it is determined that the gas meter needs to be replaced, and the menu buttons other than “replace gas meter” are inactive, but if the menu button for “replace gas meter” is not pressed after displaying the above, You may control so that it cannot change to this screen, and you may comprise so that a warning message may be displayed when changing to another screen. On the other hand, if it is determined in step 816 that the gas meter does not need to be replaced, all menu buttons shown in FIG. 10 are activated, and the work is performed when replacement work or security investigation work is performed according to the judgment of the security staff. It is possible to change to a menu for inputting.

  When the security officer displays the “Gas meter replacement” menu button, the screen changes to the gas meter replacement screen, and an input interface screen for accepting the completion of the gas meter replacement operation is displayed in the display diagram 212 (see FIG. 11). When the security personnel have finished the predetermined replacement work, the pull-down of “work completion” is set to “complete”, and the meter code of the gas meter after replacement is input. The date of work is displayed as an initial value for the replacement date. Finally, the security officer inputs a “confirm” button, so that the meter code, the replacement date, and the completion of replacement are transmitted to the gas management server 101, and the input unit 205 receives the information (step 818).

  Next, the control unit 201 acquires a record from the customer data storage unit using the two-dimensional data code received in step 801 as a key, and converts the “meter code” included in the record into the meter code received in step 818. Change and update the customer data storage unit (step 819). Further, using the meter code received in step 818 as a key, a record is acquired from the equipment data storage unit, the “installation date” included in the record is changed, and the equipment data storage unit is updated (step 820). In this embodiment, when the security officer sets the “replacement work completion” pull-down to “completed” in step 818, the “replacement” displayed as the initial value shown in FIG. Date "(February 2, 2013 shown in FIG. 11) is set. According to this step, the gas meter replacement work by the security staff is completed, and it is registered in the gas management system according to the present invention that the gas meter replacement work is completed. An input interface screen serving as a multi-function transition menu is displayed again on the unit 212. When a security worker performs a security survey or the like based on his / her own judgment, the security officer presses a “security survey” button on the input interface screen displayed again, and transitions to a security survey menu. Then, when the work by the security officer is completed, the work date and work completion may be input in a pull-down format from the screen of the security investigation menu in the same manner as the gas meter replacement menu shown in FIG. When the completion of the security survey is input, the control unit 201 uses the “supplied facility code” or “consumed facility code” included in the record of the customer data storage unit acquired in step 802 as a key (research for both facilities). If you do, update the records in the equipment data storage section using the "Supply Equipment Code" and "Consumed Equipment Code" as keys), get the record from the equipment data storage section, The date may be changed and the equipment data storage unit may be updated.

  Next, the control unit 201 transmits the change type determined in step 805 to the mobile terminal 103 via the communication control unit 207 (step 821).

  When the work so far is completed by security personnel, it is necessary to open the gas supply after the change, and after completing the opening, it is necessary to issue a prescribed document prescribed by law to the customer There is. Here, the prescribed document stipulated by law is, for example, when the demand classification is changed from the “Liquidstone Law” to the “Gas Law”, or when the calorific value exceeds a predetermined value, When changing to gas, it is necessary to issue a “gas supply agreement”. When the demand classification is changed from the “Gas Law” to the “Liquidstone Law”, it is necessary to issue the “Documents stipulated in Article 14 of the Liquid Stone Law” and the “Notice of Safety Agency Communication”. Accordingly, it is assumed that the security officer selects the “document opening printing” menu shown in FIG. 10 after performing the opening operation.

  The mobile terminal 103 may be configured to receive the change type transmitted from the gas management server 101 in step 821 and output a document according to the change type. For example, when the demand classification is changed from “Liquid stone method” to “Gas law”, the value of the indicator corresponding to the type of the change is set, and the security officer shows the “document at opening” shown in FIG. By pressing the “Print” menu button, a “gas supply contract” may be output. An output device (not shown) connected to the mobile terminal 103 may be configured to output the above-described document in response to a document issue command from the mobile terminal.

  In this way, the gas management server 101 determines the change type, transmits the indicator to the mobile terminal 103, and the mobile terminal 103 controls the output, so that the security staff outputs from the input interface screen of the mobile terminal. A document corresponding to the change type can be output without inputting the selection.

  As described above, according to the gas management system according to the embodiment of the present invention, operations such as calculation of gas charges that have been performed manually in the past can be automated, and the burden on the operator can be greatly reduced. In addition, it is possible to prevent calculation errors and the like in calculating work costs due to human error. In addition, the security personnel visiting the customer's house perform the plugging and opening work, and at the same time, the gas management system is accepted to change the gas supply form. It is possible to prevent the occurrence of inconsistency due to a delay in registration work caused by a time difference from the change registration work of the gas supply form to the gas.
