Description

[Technical Field]

[0001] The present disclosure relates to a septic tank management system, a septic tank management sticker, a septic tank management device, a septic tank management method, a septic tank management program, a computer-readable recording medium, and a device on which the program is recorded. [Background technology]

[0002] To purify domestic wastewater and other wastewater, septic tanks are used, which use the power of microorganisms to treat wastewater. These septic tanks must be maintained in an environment that allows the microorganisms to function properly, and regular maintenance and inspection work must be performed by humans. This work is outsourced to specialized businesses. Each prefecture's management department creates a septic tank management ledger, and the history of maintenance and inspection work is registered and managed in the septic tank management ledger.

[0003] However, each operator manages their work individually, and some operators manage it using paper ledgers, making it extremely difficult to grasp the maintenance status of each septic tank.In other words, while each operator generally sends the work they have done to the prefectural management department, the prefectural management department has to manually identify the relevant septic tank from the septic tank management ledger and manually update the information based on the reports from each operator to determine what work was done on which septic tank and when.

[0004] Meanwhile, a septic tank management device has been proposed that claims to be able to properly manage septic tank installation, subsequent inspection, cleaning, statutory inspection, and decommissioning (Patent Document 1). This septic tank management device, as shown in FIG. 35, updates and manages a ledger database 92 that stores management information based on status information for each septic tank transmitted from each septic tank 91. The management information includes ledger information containing any one of unique septic tank identification information, administrator information, maintenance information, operation information, and unique communication device identification information. The septic tank management device 90 includes an operation information update processing unit that updates the operation information based on operation information transmitted from each communication device 93, an abnormality processing unit that transmits confirmation information to the administrator terminal when an abnormality is detected in each septic tank, and a maintenance information update processing unit that updates the maintenance information based on maintenance work completion information. Each septic tank 91 is also equipped with a monitoring unit 94 that monitors its operation status.

[0005] However, this septic tank management device 90 requires the installation of a communication device 93 and a monitoring unit 94 in each septic tank 91, as shown in Figure 35, which is troublesome and costly. In particular, it is difficult to say that it is realistic to install communication functions and the like individually in each of the many septic tanks 91. [Prior art documents] [Patent documents]

Another object of the present disclosure is to provide a septic tank management system, a septic tank management sticker, a septic tank management device, a septic tank management method, a septic tank management program, a computer-readable recording medium, and a device on which the same are recorded, which allow for management without installing a communication function in each septic tank. Note that the description of these objects and objects of the present disclosure does not preclude the existence of other objects and objects. Furthermore, it is not necessary for one embodiment of the present disclosure to solve all of these objects. Furthermore, other objects can be extracted from the description of the specification, drawings, and claims of the present disclosure. Means for Solving the Problems and Effects of the Invention

[0008] A septic tank management system according to a first embodiment of the present disclosure is a septic tank management system for managing a plurality of septic tanks, and includes: a septic tank management database that stores a septic tank number that is individually assigned to each septic tank in advance, the location of the septic tank or the name of the manager of the septic tank, and septic tank maintenance information related to the maintenance of the septic tank; septic tank management stickers that are affixed near each septic tank and have a septic tank number display field for displaying the unique septic tank number assigned to the septic tank, and a code display field for indicating specific information including a pre-recorded arbitrary communication ID that is assigned individually from the septic tank number; a matching data storage area for storing the septic tank number displayed in the septic tank number display field of each septic tank management sticker and the communication ID included in the specific information displayed in the code display field in association with each other; and a matching operation for matching the specific information displayed in the code display field of each septic tank management sticker. a server that reads the specific information displayed in the code display field of the septic tank management sticker from the matching terminal and transmits the communication ID to the server side, associates the communication ID transmitted from the matching terminal with the septic tank number assigned to the communication ID, and stores the associated data in the matching data storage area; and a maintenance terminal that, after maintenance work for each septic tank has been performed by a maintenance worker, reads the specific information displayed in the code display field included in the septic tank management sticker for that septic tank and transmits it to the server, and the server is configured to read the specific information displayed in the code display field of the septic tank management sticker transmitted from the maintenance terminal and transmit the information to the server as maintenance work for the septic tank with the septic tank number associated with the communication ID transmitted. With the above configuration, maintenance work such as cleaning for a large number of septic tanks, which was previously performed individually by a large number of different companies, was checked manually using the septic tank numbers, making the work extremely cumbersome.However, by attaching a septic tank management sticker with a communication ID to each septic tank and reading the communication ID, this process can be automated.Furthermore, by assigning a communication ID separately from the septic tank number, it becomes possible to assign any communication ID to the septic tank number, eliminating the need to use a specific septic tank management sticker for each septic tank and providing the advantage of making it easier to link communication IDs.

[0009] In addition, the septic tank management system of form 2, in the above form, further includes a septic tank inspection form for each septic tank, which includes the septic tank number of the septic tank and septic tank maintenance information related to the maintenance of the septic tank, and when the communication ID is sent from the matching terminal to the server, the septic tank number printed on the septic tank inspection form of the septic tank to which the communication ID is to be assigned is read and sent to the server, thereby associating the communication ID with the septic tank number and recording it in the matching data storage area.

[0010] Furthermore, in the septic tank management system according to a third aspect, in any of the above aspects, the septic tank inspection slip includes a septic tank number code obtained by encoding the septic tank number, and when the communication ID is transmitted from the matching terminal to the server, the coded septic tank number printed on the septic tank inspection slip of the septic tank to which the communication ID is to be assigned is read and transmitted to the server, thereby associating the septic tank number with the communication ID and recording it in the matching data storage area. This makes it possible to prevent input errors in the septic tank number when matching the septic tank number with the communication ID.

This allows for the septic tank numbers, individually assigned in advance to be associated with arbitrary communication IDs, making it possible to identify the septic tanks by their communication IDs for subsequent work, resulting in the advantage of reducing the labor required to update the septic tank management database.

[0047] A septic tank management program according to a thirty-eighth aspect is a septic tank management program for managing a plurality of septic tanks, the program causing a computer to implement the following functions: for a septic tank management sticker affixed near each septic tank, the sticker having a septic tank number display field for displaying a unique septic tank number assigned to the septic tank, and a code display field for indicating specific information including a pre-recorded arbitrary communication ID, the communication ID being assigned separately from the septic tank number; having a matching operator read the specific information with his / her matching terminal and transmit the specific information to a server; and having the server associate the communication ID included in the specific information transmitted from the matching terminal with the septic tank number assigned to the communication ID and record the associated communication ID in a matching data storage area. This significantly reduces the labor required for recording the results of cleaning and inspections of a large number of septic tanks by a plurality of operators in a septic tank management database.

[0048] Furthermore, the septic tank management program according to a 39th aspect, in any of the above-mentioned aspects, further includes a function of having a maintenance worker performing work related to the maintenance of a septic tank, after performing the work related to the maintenance of the septic tank, read the specific information displayed in the code display field of the septic tank management sticker using a maintenance terminal owned by the maintenance worker, and transmit septic tank maintenance update information related to the maintenance of the septic tank together with the communication ID included in the specific information to the server side; and a function of having the server receive the communication ID and septic tank maintenance update information transmitted from the matching terminal, and record the maintenance work related to each septic tank together with the communication ID in a maintenance work holding area. and a function for the server to access a septic tank management database for storing the septic tank number individually assigned in advance to each septic tank, the location or manager's name of the septic tank, and septic tank maintenance information related to the maintenance of the septic tank, identify the septic tank number associated with the septic tank maintenance update information recorded in the maintenance work holding area from a septic tank ledger database in which the septic tank number corresponding to the septic tank maintenance update information recorded in the maintenance work holding area is registered by referring to the matching data holding area, and update the septic tank maintenance information related to the relevant septic tank with the septic tank maintenance update information performed by the maintenance worker who owns the maintenance terminal.

[0049] Furthermore, a septic tank management program according to a fortieth aspect is a septic tank management program for managing a plurality of septic tanks, the program having a septic tank management sticker having a septic tank number display field displaying a unique septic tank number assigned to each septic tank and a code display field showing specific information including a pre-recorded arbitrary communication ID, the communication ID being assigned separately from the septic tank number, affixed near the septic tank, the program having a function of, after a maintenance worker performs work related to the maintenance of the septic tank, the maintenance worker reads the specific information displayed in the code display field of the septic tank management sticker using a maintenance terminal owned by the maintenance worker, and transmitting septic tank maintenance update management information related to the maintenance of the septic tank together with the communication ID included in the specific information to a server side; and the server has a function of transmitting the septic tank maintenance update management information related to the maintenance of the septic tank to the maintenance terminal. and a server accesses the septic tank management database, identifies the septic tank number associated with the communication ID of the septic tank maintenance update information from a septic tank ledger database that registers the septic tank number corresponding to the septic tank maintenance update information recorded in the maintenance work holding area by referring to a matching data holding area in which the communication ID and the septic tank number are associated and recorded, and updates the septic tank maintenance information for the relevant septic tank with the septic tank maintenance update information performed by the maintenance worker who owns the maintenance terminal. This significantly reduces the labor required to record the results of cleaning and inspections by multiple workers for a large number of septic tanks in the septic tank management database.

[0050] Furthermore, a computer-readable recording medium or device storing the program according to any of the above embodiments is provided in accordance with the 41st aspect.

[0052] Embodiments of the present disclosure will be described below with reference to the drawings. However, the embodiments described below are merely examples for embodying the technical concepts of the present disclosure, and the present disclosure is not limited to the following. Furthermore, this specification does not in any way specify the components set forth in the claims to be those of the embodiments. The dimensions, materials, shapes, relative positions, etc. of components described in the embodiments are not intended to limit the scope of the present disclosure, and are merely illustrative examples, unless otherwise specified. The size and positional relationships of components shown in the drawings may be exaggerated for clarity. Furthermore, in the following description, the same names and symbols indicate components that are identical or of the same quality, and detailed descriptions will be omitted as appropriate. Furthermore, the elements constituting the present disclosure may be configured with the same components, such that multiple elements are shared by one component, or conversely, the functions of one component may be shared by multiple components. [Embodiment 1]

[0053] A septic tank management system 1000 according to a first embodiment of the present disclosure is shown in Fig. 1. The septic tank management system 1000 shown in this figure is a system that stores information for managing multiple septic tanks 1 in a septic tank management database 40. This septic tank management system 1000 is composed of the septic tank management database 40, a matching data storage area 20, septic tank management stickers 10 provided on each septic tank 1, a worker database 50, a server 30, and a worker terminal 2. The server 30 has a maintenance work storage area 52.

[0054] The management work storage area 52 may be configured separately from the server 30. For example, in a septic tank management system 2000 according to a modified example shown in Fig. 2, the management work storage area 52 is configured as a storage area, for example, a database, separate from the server 30.

[0055] The server 30 and the worker database 50 constitute the septic tank management device 100. In the example of FIG. 1 etc., the server 30 and the worker database 50 are realized by a cloud computing service. The septic tank management system and the septic tank management device may be configured on a dedicated server, or may be configured as a rental server or a cloud server. For example, in the septic tank management system 3000 according to a modified example shown in FIG. 3, the server 30, the matching data storage area 20, the septic tank management database 40, the worker database 50, and the maintenance work storage area 52 are configured as a cloud server. (Septic tank 1)

[0056] Septic tank 1 uses the action of microorganisms to treat wastewater, such as human waste and domestic wastewater, by purifying it. It is necessary to maintain an environment in the tank that allows the microorganisms to function properly, and maintenance work is required to be done by humans.

[0057] Maintenance work includes regular maintenance inspections, cleaning, and statutory inspections, and each of these maintenance tasks is outsourced to specialized companies. Maintenance inspections are performed by maintenance inspection companies and include tasks such as adjusting the sludge in the septic tank and inspecting the blower. While this varies depending on the tank size and model, it is usually performed at least three times a year. Cleaning is performed by cleaning companies and involves removing the sludge and scum that is generated when microorganisms treat water in the septic tank, and cleaning and sanitizing the equipment and machinery to restore the tank's functionality. While this varies depending on the tank size and model, it is usually performed at least once a year.

[0058] Furthermore, legal inspections are carried out by legal inspection businesses (designated inspection agencies). Legal inspections include an Article 7 inspection, which is carried out 3 to 8 months after the start of use to check whether construction has been carried out properly and whether the septic tank is functioning as intended, and an Article 11 inspection, which is carried out once a year. The Article 11 inspection checks whether maintenance, inspection, and cleaning have been carried out properly and whether the septic tank is functioning normally.

[0059] In this disclosure, workers who perform these maintenance tasks are referred to as maintenance workers. Meanwhile, workers who perform the matching work described below are referred to as matching workers. In this disclosure, the term "worker" includes both maintenance workers and matching workers. Furthermore, among the worker terminals 2 operated by the workers, the worker terminal 2 operated by the maintenance worker PB is referred to as the maintenance terminal 2B, and the worker terminal 2 operated by the matching worker PA is referred to as the matching terminal 2A. These maintenance terminals 2B and matching terminals 2A can be network-connectable mobile devices such as general-purpose smartphones, tablets, and PCs. Furthermore, when executing the maintenance program or matching program as the septic tank management program described below on the maintenance terminal 2B or the matching terminal 2A, a web application using an Internet browser can be suitably used. However, a dedicated application for executing the septic tank management program may be prepared and installed on each worker terminal for execution.

[0060] In order to keep track of each stage of the installation, maintenance, and decommissioning of septic tanks, prefectural management departments create and manage septic tank management ledgers, and the history of the above-mentioned maintenance, inspection, and cleaning is registered in these septic tank management ledgers.

[0061] However, each company that performs maintenance, inspections, cleaning, and statutory inspections manages their work individually, and some companies even use paper ledgers, making it extremely difficult to grasp the maintenance status of each septic tank. Generally, each company sends the work they have performed to the prefectural management department. Based on reports from each company, the prefectural management department must manually identify the relevant septic tanks in the septic tank management ledger and update the information to reflect when maintenance, inspection, cleaning, and statutory inspections were performed. For example, in Tokushima Prefecture alone, there are approximately 200,000 septic tanks as of the end of March 2023. The maintenance work is extremely tedious, and a more labor-saving and error-free management method is highly desirable.

[0062] Furthermore, securing toilets has been noted as important to the lives of evacuees in recent disasters, such as the Noto Peninsula earthquake in early 2024. Many evacuees say they would rather live at home than in an evacuation shelter if their toilets are usable, and from a disaster prevention perspective, it is therefore necessary to build a system that can quickly and efficiently inspect and manage septic tanks in the event of a disaster, such as checking whether they have been damaged by an earthquake or other disaster.

[0063] In light of this background, the septic tank management system 1000 according to this embodiment simplifies the recording and updating work for maintenance and management, and aims to digitalize the management of the septic tank 1. Specifically, it simplifies the work of updating the septic tank management database 40, which corresponds to the septic tank management ledger managed by the local government.

[0064] The septic tank management database 40 stores the septic tank number assigned to each septic tank 1 in advance, the location where each septic tank 1 is installed, the name of the manager of the septic tank 1, and septic tank maintenance information related to the maintenance of the septic tank 1, in association with each other. Basically, this corresponds to the existing septic tank ledger system managed by each local government, for example, prefecture. The septic tank maintenance information includes information such as the construction purpose of the septic tank, the date of start of use, the name of the septic tank manufacturer, the construction company, the discharge destination, the type of septic tank, the treatment method, the target water quality for treatment, the amount of septic tank and sewage, etc. (Septic tank management sticker 10)

[0065] The septic tank management sticker 10 displays the septic tank number and is distributed to organizations entrusted by local governments with the management of each septic tank and issued with a septic tank affixing worker's certificate. The septic tank management sticker 10 is affixed near each septic tank 1. While the septic tank management sticker 10 may be affixed directly to the septic tank, septic tanks are generally installed in difficult-to-access locations, such as underground. Therefore, the septic tank management sticker 10 is preferably affixed in an easily accessible or visible location near the septic tank 1. For example, the sticker 10 may be affixed outdoors near the septic tank 1, such as on a water faucet post, a rain gutter, around the outlet for a blower installed outside the septic tank to supply oxygen to the septic tank, or at the entrance or foyer of the building where the septic tank 1 is installed. Preferably, the sticker 10 is affixed to a flat surface under the roof, such as under the eaves, that is less exposed to wind and rain. In this disclosure, the term "affixing the septic tank management sticker 10 to the septic tank 1" may be used for convenience, including affixing the sticker near the septic tank 1.

[0066] Furthermore, it is preferable that the septic tank management sticker 10 be made of a weather-resistant material so that it can be attached outdoors and maintained for a long period of time even when exposed to rain and wind. This makes it possible to read the specific information displayed in the code display field 14 of the septic tank management sticker 10 for a long period of time, even in an exposed environment. For example, it may be made of a resin such as PET or polyester. The surface may also be protected with a protective layer, such as a translucent PET laminate.

[0067] The back side of the septic tank management sticker 10 is an adhesive layer with adhesive properties, and as shown in FIG. 4, multiple stickers are provided attached to a mount. Each septic tank management sticker 10 is assigned a different communication ID. In the example of FIG. 4, a 9-digit number is assigned consecutively from top to bottom as the communication ID. Also, on the mount, next to each septic tank management sticker, a communication ID seal showing the communication ID is attached. (ID sticker for communication)

[0068] It is preferable that the communication ID sticker be affixed to the septic tank inspection slip 60 (see FIG. 6, described later) of the septic tank to which the communication ID of the septic tank management sticker is assigned during the matching process. This physically prevents transcription errors in the communication ID assigned to the septic tank number. The column for affixing the communication ID sticker may be provided on the septic tank inspection slip 60, or it may be affixed to an appropriate position outside the column.

[0069] Returning to the explanation of the septic tank management sticker 10, as shown in Figure 4, each septic tank management sticker 10 has a septic tank number display field 12 and a code display field 14. If necessary, the name and mark of the managing local government may also be added. In the example of Figure 4, the Tokushima Prefecture emblem is displayed along with the words "Tokushima Prefecture Septic Tank Register," indicating that the septic tank is managed by Tokushima Prefecture. (Septic tank number display column 12)

[0070] The septic tank number display field 12 is a field for displaying the unique septic tank number assigned to the septic tank 1. This field is initially left blank so that the matching worker PA can write it in by hand. In other words, by deliberately not specifying a septic tank number when creating the septic tank management sticker 10, any septic tank management sticker 10 can be used. As a result, mistakes such as mix-ups can be avoided when affixing the septic tank management sticker 10 to the septic tank 1. If septic tank management stickers with septic tank management numbers printed on them were to be prepared in advance, the correct septic tank management sticker would need to be brought with them before leaving for the site when affixing the stickers to each septic tank. Furthermore, once at the site, the septic tank management sticker with the correct number would need to be found and affixed, which would make mistakes such as mix-ups more likely to occur. In contrast, the septic tank management system 1000 of this embodiment allows any septic tank management sticker 10 to be used, and when affixing the sticker, the septic tank number of the septic tank 1 in question is written by hand, simplifying the work and greatly reducing the occurrence of errors. (Code display field 14)

[0071] The code display field 14 is a field that shows specific information including a pre-recorded arbitrary communication ID. The communication ID serves to identify the septic tank 1 when communicating with the worker terminal 2, the server 30, etc. In the example of FIG. 4, the communication ID is a nine-digit number, but is not limited to this. The type of characters used is not limited to numbers and may include European letters, symbols, etc., and the number of digits may be increased or decreased. In addition, the communication ID is different for each septic tank management sticker 10. By assigning an arbitrary septic tank number to this communication ID, it becomes possible to uniquely identify and manage the septic tank 1.

[0072] The communication ID is inherently independent of the septic tank number. Although a coincidence between the IDs is probabilistic, the communication ID is essentially an independent number assigned separately from the septic tank number. The matching operator PA can assign any communication ID, i.e., any septic tank management sticker, to any septic tank number. As a result, the communication ID can be used to identify the septic tank in communications using the operator terminal 2, eliminating the need for manual identification and realizing a highly user-friendly septic tank management system. Although the addition of the communication ID separate from the septic tank number requires a new matching task to link the communication ID to the septic tank number, this task is easy to perform. Furthermore, once the matching task is completed, all subsequent tasks can be handled using the communication ID, resulting in increased convenience. Furthermore, if the septic tank management sticker deteriorates or is damaged, the previous records can be retained by simply replacing it with a new one and matching the new communication ID, enabling the septic tank management system to continue operating uninterrupted. (Specific information)

[0073] The specific information displayed in the code display field 14 includes URL information for accessing the server 30 and a character string for initially inputting a communication ID. The initial input refers to accessing the URL and simultaneously specifying the communication ID. This allows the worker terminal 2 to read the specific information, access the corresponding URL of the server 30, and log in with the communication ID specified.

[0074] The specific information can also be a code that encodes a character string representing the specific information. This allows information such as a communication ID to be recorded in the code, reducing errors when the code is read by the worker terminal 2 and allowing for smooth and rapid input of the specific information. The code can be a one-dimensional code such as a barcode, or a two-dimensional code such as a QR Code (registered trademark). QR Code (registered trademark) is particularly preferred due to its versatility, including fast response and easy readability on general-purpose smartphones and tablets. However, the present disclosure does not limit the code to a QR Code (registered trademark). Other two-dimensional codes, such as matrix types (matrix symbol systems) such as Data Matrix and VeriCode, and stacked types (multi-row symbol systems) such as PDF417 and CODE49, can also be used. Alternatively, numbers or character strings can be directly used as the code instead of a code that requires encoding. In this case, the code can be read using OCR. Furthermore, instead of these printed codes, RFID tags embedded in stickers can also be used as the code. In this case, the septic tank management sticker can serve as an IC tag. As such, septic tank management stickers do not necessarily have to be in the form of a seal, and the term is used to include tag-like and plate-like forms as well, not limited to the name.

[0075] It is also preferable that the septic tank management sticker 10 does not include personal information. Here, only the septic tank number is displayed, and personal information such as an address or a person's name is not displayed, nor is it included in the identifying information. This makes it possible to prevent personal information from being leaked from the affixed septic tank management sticker 10. Furthermore, even if information is leaked on the cloud server side, the leakage of personal information can be minimized, thereby enhancing security.

[0076] If the septic tank management sticker 10 deteriorates after a certain period of time, for example, if the specific information in the code display field 14 or the septic tank number in the septic tank number display field 12 becomes unreadable, a new septic tank management sticker 10 is affixed and the matching process is performed again. In this way, the septic tank management system 1000 can be maintained stably over a long period of time, regardless of the lifespan of the septic tank management sticker 10. (Matching data storage area 20)

[0077] The matching data storage area 20 is an area for storing the septic tank number displayed in the septic tank number display field 12 of each septic tank management sticker 10 in association with the communication ID included in the specific information displayed in the code display field 14. The process of associating the septic tank number with the communication ID is called matching (details will be described later). The matching results are stored in this matching data storage area. A local file server or database can be used for this matching data storage area 20. In the example of Figure 1, it is located in the same place as the septic tank management database 40, but it may also be located in a different location and connected to a separate network. Note that the file server function can also use a cloud service as shown in Figure 3, but considering security risks such as information leakage, it is preferable not to upload the data to the cloud as shown in Figure 1. (Septic Tank Management Database 40)

[0078] The septic tank management database 40 stores the septic tank number assigned to each septic tank in advance, the location (address) where the septic tank is installed, the name of the manager who manages the septic tank, and septic tank maintenance information related to the maintenance of the septic tank. Such a septic tank management database can use the existing septic tank ledger system owned by each local government.

[0079] The septic tank management database does not have information on the communication ID, but by referring to the matching data storage area, updates the septic tank maintenance information with the septic tank maintenance work category of the maintenance worker PB, which is sent together with the communication ID. However, after the matching work is completed, the septic tank management database 40 may have a communication ID, or the matching data storage area may be integrated into the septic tank management database. (Worker database 50)

[0080] The worker database is a database for pre-registering worker information including the name of the maintenance worker PB who uses each maintenance terminal 2B. The worker database registers the name, email address, affiliation (management company name), and type of septic tank maintenance work (work category) of the maintenance worker PB who uses the maintenance terminal 2B. Here, by using the email address as a search key, it is possible to obtain the name, affiliation, and type of maintenance work of the maintenance worker PB who operated the maintenance terminal 2B linked to the email address.

[0081] In this example, the worker database is configured to identify worker information from an email address, but the configuration is not limited to using an email address as a search key. It goes without saying that the configuration may also be such that worker information is identified using other worker information, such as the maintenance worker's name or ID number, as a search key. Furthermore, the term "worker" here refers primarily to a maintenance worker who performs maintenance work on septic tanks. In other words, it does not generally include matching workers who perform matching work. However, if a matching worker also serves as a maintenance worker, the worker may be included in the worker database.

[0082] In the example of Figure 5, the maintenance worker PB who performs the statutory inspection is also in charge of the cross-checking work. In other words, among the maintenance workers PB, the maintenance worker PB who performs the statutory inspection also serves as the cross-checking worker PA. By having the maintenance manager who performs the statutory inspection double as the cross-checking worker PA in this way, when performing the statutory inspection that is required for each septic tank, by having them affix a septic tank management sticker and cross-check the communication ID with the septic tank number, the cross-checking work can be carried out sequentially along with the statutory inspection, and the spread of septic tank management systems can be efficiently promoted.

[0083] However, the present disclosure is not limited to this configuration, and a maintenance worker who performs maintenance work other than statutory inspections may also serve as a matching worker. Alternatively, a matching worker may be appointed separately from the maintenance worker. (Maintenance work holding area 52)

[0084] The maintenance work holding area 52 is an area for holding the maintenance work for each septic tank together with a communication ID. After a maintenance worker PB performs maintenance work for each septic tank, the maintenance worker PB reports the maintenance work to the septic tank management system, and the maintenance work is recorded in the maintenance work holding area 52 together with the communication ID as septic tank maintenance update information. A cloud server can be preferably used for such a maintenance work holding area 52. In the example of FIG. 1, the maintenance work holding area 52 is realized as part of the server 30. However, the maintenance work holding area 52 can take any form, such as a file server or a database.

[0085] The contents of the maintenance work recorded in the maintenance work holding area 52 include information identifying the septic tank, in this case a communication ID, the name of the maintenance worker PB who performed the maintenance work, their affiliation, the date and time the maintenance work was performed, the work category, etc. In the maintenance work holding area 52, the septic tank is identified not by the septic tank management number but by the communication ID on the septic tank management sticker 10. Preferably, personal information such as the septic tank number or the location where the septic tank is installed is not included in the maintenance work holding area 52. This reduces the risk of information related to the personal identification of general users being leaked to the outside even if information on the cloud server is leaked, etc.

[0086] Furthermore, when the maintenance worker PB reports the maintenance work he or she has performed to the septic tank management system server 30 via the maintenance terminal 2B, the server 30 registers this septic tank maintenance update information together with a communication ID in the maintenance work holding area 52. The server 30 then further registers the septic tank maintenance update information registered in the maintenance work holding area 52 in the septic tank management database 40. At this time, the server 30 references the matching data holding area 20 to identify the septic tank number linked to the communication ID. As a result, the septic tank maintenance update information registered in the maintenance work holding area 52 is reflected in the corresponding septic tank in the septic tank management database 40.

[0087] Although the maintenance work holding area 52 is shown as a separate database in the example of FIG. 1 etc., the present disclosure is not limited to this configuration, and it may be integrated with other databases, such as the worker database 50. (Server 30)

[0088] During operation of the septic tank management system, the server 30 receives the communication ID sent from the maintenance terminal 2B, identifies the septic tank number associated with the matched communication ID, and accesses the septic tank management database 40. Then, the server 30 updates the septic tank maintenance information for the corresponding septic tank 1 with the work related to the maintenance of the septic tank performed by the maintenance worker PB who owns the maintenance terminal 2B. This allows the report of the septic tank maintenance work performed from the maintenance terminal 2B to be promptly reflected in the septic tank management database.

[0089] Meanwhile, when building a septic tank management system, i.e., during reconciliation work, the server associates the communication ID sent from the reconciliation terminal 2A with the assigned septic tank number and records it in the septic tank management database. This makes it possible to link any communication ID to the septic tank numbers individually assigned to numerous septic tanks, making it possible to identify septic tanks using the communication ID in subsequent work, which has the advantage of reducing the labor required to update the septic tank management database. In particular, by associating any communication ID rather than using a pre-assigned number such as a septic tank number, any septic tank management sticker can be used, reducing the likelihood of mistakes such as attaching the wrong sticker. This improves on-site usability and convenience, reduces tedious work and the labor required to check for errors, and promotes the digitalization of septic tank management.

[0090] Such a server 30 may include a matching data storage area 20. In particular, by using a general-purpose cloud service or the like having a file server function to construct the server 30 and the matching data storage area 20, it is possible to obtain the advantage that the septic tank management system 1000 can be constructed inexpensively. (Worker terminal 2)

[0091] The worker terminal 2 is a terminal such as a matching terminal 2A or a maintenance terminal 2B carried by the worker, i.e., the matching worker PA or the maintenance worker PB, and can be a small information device that can be connected to a network, such as a smartphone, tablet, or laptop. In particular, a smartphone with a camera function is preferable, as it can read codes and perform data communication.

[0092] The maintenance worker PB uses the maintenance terminal 2B to read the specific information displayed in the code display field 14 of each septic tank management sticker 10. Then, the maintenance worker PB transmits the communication ID to the server 30 side.

[0093] In this way, the work of recording the results of cleaning and inspections performed by multiple maintenance workers PB on multiple septic tanks 1 in the septic tank management database 40 can be significantly reduced. In particular, the previously tedious work of identifying which septic tank 1 each maintenance worker PB performed work on can be identified by reading the specific information displayed on the septic tank management sticker 10 and referencing the matching data storage area 20 for the septic tank number linked to this communication ID. As a result, the matching work that was previously performed manually is no longer necessary, and the results of each work performed by the maintenance workers PB can be smoothly reflected in the septic tank management database 40, allowing the work to be recorded and managed. In this way, the work of updating the septic tank management database 40 can be significantly reduced, and the digitalization of septic tank management can be achieved. (Setting up a septic tank management system)

[0094] FIG. 5 shows a block diagram illustrating the flow of setting up and operating this septic tank management system 1000. As shown in this diagram, when the septic tank management system 1000 is launched, a necessary setup task involves a matching worker PA matching the communication ID with the septic tank number. Here, the matching worker PA heads to the installation site of the septic tank 1 with a septic tank management sticker 10 and a septic tank inspection slip 60 that lists details of the relevant septic tank. The worker here refers to the matching worker who matches the septic tank number with the communication ID. Typically, the matching worker is an employee of the company that operates the septic tank management system. Furthermore, a statutory inspection of the septic tank may be conducted at the same time as the matching task. (Septic Tank Inspection Sheet 60)

[0095] An example of a septic tank inspection form 60 is shown in Figure 6. The septic tank inspection form 60 is a sheet containing information for each septic tank 1, such as the septic tank number, the address of the installation location, and the name of the person responsible for managing the tank. It is called a field notebook or similar and is generally prepared by an inspection organization designated by the prefectural governor that inspects the septic tank 1. The second row in the upper left corner of the septic tank inspection form 60 has a septic tank number display field 62, which displays the numerical value of the septic tank number. In addition, a septic tank number barcode 61, which encodes the septic tank number, is displayed in the upper right corner as a septic tank number code. By scanning the septic tank number barcode 61, the septic tank number can be accurately entered. Note that the septic tank number code may be a code other than a barcode, such as a two-dimensional code. However, by separating the septic tank number code into a barcode and the communication ID into a QR code, the risk of errors, such as code mix-ups, by the matching worker PA can be reduced.

[0096] Furthermore, the septic tank inspection slip 60 contains information on septic tank maintenance and management, including information on statutory inspections, which are part of the maintenance and management work. (Maintenance work number sticker 65)

[0097] Furthermore, maintenance work number stickers 65 may be prepared that indicate maintenance work numbers for individually identifying work related to the maintenance of the septic tank performed by the maintenance worker PB. Each maintenance work number sticker 65 displays a sticker number. A maintenance work number can be assigned to the sticker number for identifying work related to the maintenance of the septic tank performed by the maintenance worker PB. The sticker number is preferably coded as a barcode, two-dimensional code, or the like. Here, it is written as a JAN code. However, Arabic numerals or symbols may also be displayed directly without coding. In this case, the sticker number can be read using OCR.

[0098] Each time maintenance worker PB performs septic tank management work, he prepares a new maintenance work number sticker 65, preferably affixing it to the sticker field on the septic tank inspection form 60 as shown in FIG. 6, and reads the sticker number on this maintenance work number sticker 65 with the maintenance terminal 2B to register it on the server side. For example, after completing septic tank management work, he reads the QR code in the code display field 14 on the septic tank management sticker 10 to report the septic tank management work, and also reads the maintenance work number sticker 65, and registers the maintenance work number on the server. In this way, the septic tank management work performed by maintenance worker PB is registered on the server side.

[0099] It is possible to prepare multiple sheets of the same maintenance work number sticker 65. For example, three maintenance work number stickers 65 for each sticker number can be set up, and one sticker can be affixed to the septic tank inspection slip 60 when reporting the maintenance work. The remaining two stickers can be affixed to the sample bottle for the liquid sample collected from the septic tank, or to a copy of the receipt issued to the septic tank manager when making a cash payment, making it easier to manage each septic tank maintenance work.

[0100] Furthermore, a new maintenance work number sticker 65 is added for each maintenance work. For example, when regular maintenance work is performed on the same septic tank, a new numbered maintenance work number sticker 65 is affixed to the septic tank inspection slip 60 issued for each maintenance work. This makes it possible to individually identify each septic tank maintenance work for the same septic tank. The example in Figure 6 shows an example of a statutory inspection as a septic tank maintenance work. (Butting work)

[0101] The procedure for the matching worker PA to perform the matching work will be explained below based on the flowchart in Figure 7. First, the matching worker PA goes to the site where the septic tank is installed and manually affixes the septic tank management sticker 10 near the septic tank 1. At this time, the matching worker PA carefully explains the significance and necessity of the septic tank management sticker 10 to the septic tank manager, typically the resident of the house where the septic tank is installed. Then, the matching worker PA attempts to obtain direct consent from the septic tank manager (step S1).

[0102] If direct consent cannot be obtained because the person in charge is not present or is unable to make a decision, an explanatory leaflet like the one shown in Figure 8 explaining the need to affix septic tank management stickers is distributed by hand or by post (step S2).

[0103] Next, the checking worker PA handwrites the septic tank number in the septic tank number display field 12 as shown in FIG. 9 (Step S3). The checking worker PA confirms the septic tank number by referring to the septic tank inspection form 60 shown in FIG. 6 that the checking worker PA has brought with him. When writing the septic tank number by hand, a writing implement using ink with excellent weather resistance is used. For example, an oil-based pen using oil-based ink that does not fade easily is used. In this embodiment, Big Man Powerful Paint Marker or Mitsubishi Pencil Paint Marker (both are product names) are used. This makes it possible to ensure that the septic tank number will not fade easily even if the septic tank management sticker 10 is left exposed to the elements for about five years.

[0104] Then, a septic tank management sticker with the septic tank number written on it, as shown in FIG. 9, is affixed near the septic tank (step S4). For example, if direct consent is obtained from the septic tank manager, the sticker is affixed in a conspicuous location, such as the entrance to the building. This makes it easier to confirm that the sticker has been registered in the septic tank management system 1000. It also makes it easier for someone else (typically a maintenance worker) to find the septic tank management sticker 10 during inspection or cleaning. On the other hand, if direct consent is not obtained from the septic tank manager (typically, if the manager is not at home when a visit is made to the house where the septic tank is installed), the septic tank management sticker is affixed near the septic tank. For example, the sticker is affixed near the inspection certificate for the septic tank 1. An explanatory leaflet (such as an explanatory leaflet titled "Notice from Tokushima Prefecture") informing the owner that the septic tank maintenance sticker has been affixed is received and placed in a mailbox or similar. In either case, it is preferable to affix the sticker to a flat, smooth surface so that the code displayed on the septic tank management sticker 10 can be easily read. Also, the sticker should be affixed so as not to overlap with other stickers, such as inspection certificates, gas stickers, and broadcasting station stickers.

[0105] It is preferable that the matching worker PA handwrite the septic tank number in the septic tank number display field 12 of the septic tank management sticker 10 immediately before attaching the septic tank management sticker 10. This is because, particularly when the septic tank management sticker 10 is to be attached to a curved surface such as a pipe, it is difficult to write in the septic tank number display field 12 after attachment. However, if the surface to be attached is flat, the matching worker PA may write the septic tank number in the septic tank number display field 12 after attachment.

[0106] The matching worker PA also links the septic tank number with the communication ID of the affixed septic tank management sticker 10 (step S5). After filling in the septic tank number and affixing the septic tank management sticker 10 to the septic tank as shown in FIG. 9, the matching worker PA takes a photo of the affixed septic tank management sticker 10 (step S6). The photo is taken using the camera of the smartphone, which is the matching terminal 2A. This image is sent to the server 30. The image of the septic tank management sticker 10, which has actually been affixed and has the septic tank number written in it, is then saved on the septic tank management database 40 side. This allows the matching worker PA to later check for errors in the handwritten septic tank number, check the communication ID, and recover from any errors that may have occurred during matching (correct errors or rematch). It also allows the matching worker PA to confirm which part of the septic tank management sticker 10 was affixed. Furthermore, if the matching worker PA forgets to perform the on-site matching, matching can be performed by scanning a QR code containing specific information contained in the image without having to go back to the site. To take a photograph, for example, a "take a photograph" button 128 is pressed on the data registration screen 120 in FIG. 15, which will be described later.

[0107] The above-mentioned steps of distributing the explanatory leaflet (step S2), writing down the septic tank number (step S3), attaching the septic tank management sticker (step S4), linking the septic tank number to the communication ID (step S5), and photographing the septic tank management sticker 10 (step S6) may be carried out in any order as appropriate.

[0108] The linking work by the matching worker PA in step S5, i.e., the work of matching the septic tank number and communication ID, is performed using a septic tank management program. The septic tank management program can be a dedicated application installed on the matching terminal 2A held by the matching worker PA, or a web application operated via a web browser. Here, the matching program was built as part of the septic tank management program using Cybozu Inc.'s kintone (service name), but it goes without saying that other cloud services may also be used. A specific procedure for matching work using the matching program will be described with reference to Figures 10 to 14. (matching program)

[0109] First, the septic tank number is entered at the installation site of the septic tank 1. Specifically, a matching terminal 2A is used to access a dedicated site for matching work. Here, as shown in FIG. 10, a septic tank search screen 110 is displayed for searching for the facility to be inspected, i.e., the septic tank 1. In the following example, the septic tank number is referred to as the "facility number." (Septic tank search screen 110)

[0110] The septic tank search screen 110 has a septic tank number input field 112, a barcode read button 114, and a search button 116. The septic tank number can be directly input and specified in the septic tank number input field 112. In this case, the barcode read button 114 is pressed. This starts the camera, making it possible to read the barcode. The septic tank inspection form 60 shown in FIG. 6 is then taken out and the septic tank number barcode 61 displayed in the upper right corner of the septic tank inspection form 60 is read. The septic tank number obtained by decrypting the read septic tank number barcode 61 is then automatically entered into the septic tank number input field 112 as shown in FIG. 11. The matching worker PA confirms that the septic tank number displayed in the read septic tank number display field 12 matches the septic tank number in the septic tank number display field 62 written in the second row from the top left of the septic tank inspection form 60. Then, when the search button 116 is pressed, the septic tank with the corresponding septic tank number is searched for in the septic tank management database 40, and the data registration screen 120 shown in FIG. 12 is displayed. In this way, instead of manually entering the septic tank number, the matching worker PA reads and enters the septic tank number printed on a septic tank inspection sheet such as a field notebook using the matching terminal 2A, thereby preventing input errors in the septic tank number and ensuring reliable matching of the septic tank number and communication ID. Also, as described above, a photo of the septic tank management sticker 10 affixed near the septic tank is taken. Specifically, the "Take Photo" button 128 is pressed on the data registration screen 120 in FIG. 15 to take a photo. (Data registration screen 120)

[0111] The data registration screen 120 includes a facility number (septic tank number) display field 121, a facility name display field 122 showing the name of the facility where the septic tank 1 is installed, a communication ID input field (QR code) 123, and a QR code read button 124. Pressing the QR code read button 124 activates the camera, enabling the QR code to be read. The QR code displayed in the code display field 14 of the septic tank management sticker 10 shown in FIG. 9 is read. The communication ID obtained by decrypting the read QR code is automatically entered into the communication ID input field 123, as shown in FIG. 13. In this state, the matching operator PA scrolls through the data registration screen 120 and presses a result data send button 125, as shown in FIG. 14. This instructs the matching terminal 2A to execute the matching work, and the association between the septic tank number and the communication ID is recorded in the matching data storage area 20. The matching operator PA performs the above work at the site where the septic tank 1 is installed. Then, after returning to the office, the employee creates a daily report and registers it, completing the reconciliation process.

[0112] The above describes an example of matching a septic tank number and a communication ID by data communication using the matching terminal 2A. This method assumes an environment where data communication is possible. However, some locations, such as mountainous areas or remote locations, may be out of communication range, have poor reception, or have unstable communication. Data communication may also be temporarily unavailable due to communication failures. In such cases, as described above, an image of the septic tank management sticker 10 affixed near the septic tank at the site is captured using a smartphone camera. Then, when the matching worker PA leaves the site and enters communication range, the registration work is performed using the captured image. Specifically, as shown in FIG. 15, the data registration screen 120 is displayed and the photo library button 126 is pressed to retrieve the captured image. Here, as shown in FIG. 16, the image of the captured septic tank management sticker 10 is displayed on the image attachment screen 130, and the image is sent to the matching data storage area 20 by pressing the image send button 132. This image is then used for matching. This makes it possible to match the septic tank number with the communication ID regardless of the radio wave conditions at the location where the septic tank is installed.

[0113] Furthermore, by having the matching worker PA handwrite the septic tank number of the septic tank 1 to which the septic tank management sticker 10 is affixed in the septic tank number display field 12 of the septic tank management sticker 10, which is left blank in advance, it becomes possible to link any septic tank number to the communication ID of the septic tank management sticker 10. As a result, compared to, for example, preparing a sticker with the septic tank number printed in advance, it is possible to eliminate the effort of searching for a sticker with the corresponding septic tank number and also to prevent mistakes such as mixing up septic tank numbers, improving convenience.

[0114] If stickers with QR codes that directly encode the septic tank numbers were created, the matching work would be unnecessary. However, in this case, the QR code stickers would need to be printed on-site. In this case, a printer with communication capabilities would need to be prepared for each worker, and the workers would have to carry the printer with them and print the codes on-site, which would require a large capital investment and be time-consuming.

[0115] On the other hand, it is also possible to print stickers with QR codes that encode the septic tank numbers in advance and carry them to the site. However, in this case, it is necessary to search for the sticker that corresponds to the septic tank number of the site and prepare it before the visit, and at the site, it is necessary to search for the necessary sticker from the multiple stickers that you have carried, which is a cumbersome task. There is also the possibility of mistakes such as mixing up the stickers or attaching them to the wrong place.

[0116] In contrast, the septic tank management system 1000 according to this embodiment allows any septic tank management sticker 10 to be affixed on-site, and the work is performed by checking the communication ID assigned to the affixed septic tank management sticker 10, resulting in extremely excellent workability. Furthermore, by having the septic tank number written by hand on the sticker on-site, mistakes such as affixing the wrong septic tank management sticker 10 do not occur. In addition, since the septic tank number on the septic tank management sticker 10 can be confirmed after the septic tank number has been written, any entry errors can be checked.

[0117] In this way, by using a communication ID instead of using the septic tank number as is, on-site work at the installation site of each matched septic tank 1 can be simplified, and a septic tank management system 1000 that is less likely to cause errors can be realized.

[0118] Furthermore, by not storing the matching data storage area 20, which stores the septic tank number, on the cloud, the risk of personal information leaks can be reduced. The matching data storage area 20 is linked to the septic tank management database 40. The matching worker PA sends the communication ID and septic tank number, encoded in a QR code, from the matching terminal 2A and stores them in the matching database. When the matching worker PA creates a daily report of the matching work and registers it, the communication ID is matched with the septic tank number in the septic tank management database 40, and this associated information is recorded in the septic tank management database 40. After the matching is complete, information from the maintenance terminal 2B, etc. is input to the server 30. The server 30 registers septic tank maintenance information using the communication ID to the septic tank number associated with the same communication ID in the septic tank management database 40.

[0119] Furthermore, septic tanks are inspected periodically, such as annually. During this inspection, if the septic tank number on the septic tank management sticker 10 has faded or disappeared due to aging or other reasons, the matching worker PA rewrites the septic tank number. Furthermore, if the septic tank management sticker 10 is significantly deteriorated, a new septic tank management sticker 10 is affixed and the matching work is redone. As a result, a new communication ID is linked to the septic tank number, and the matching data storage area 20 is updated. In this way, it is possible to maintain and update the septic tank management system regardless of the deterioration of the septic tank management sticker 10. (Septic tank maintenance work)

[0120] On the other hand, the maintenance workers PB who perform septic tank maintenance work are generally separate from the checklist workers PA who perform cross-checking work. Typically, the checklist workers PA who perform cross-checking work are employees of the company that operates the septic tank management system. Furthermore, the maintenance workers PB who perform septic tank maintenance work, such as septic tank maintenance and inspection, cleaning, and statutory inspection, are employees of the respective businesses that specialize in these tasks, and are usually employees of an outsourced company that is different from the system operating company. In this disclosure, each maintenance worker PB is registered in advance to distinguish between these maintenance workers PB. Specifically, the email address is used to distinguish between the work they are responsible for, whether it is cross-checking work, septic tank maintenance and inspection, cleaning, or statutory inspection.

[0121] In this disclosure, the maintenance worker is not limited to one person, but is assumed to be multiple maintenance workers who divide the work and perform maintenance work on multiple septic tanks. Specifically, it is assumed that multiple maintenance workers belonging to different contractors share the maintenance work of various septic tanks. Furthermore, in the example of this disclosure, it is assumed that the butting worker who performs the butting work and the maintenance worker who performs the septic tank maintenance work are different persons, but they may be the same person. In this disclosure, among the maintenance work, the butting worker PA performs the statutory inspection. In other words, as shown in Figure 5, the butting worker PA also serves as the maintenance worker PB who performs the statutory inspection, which is one of the maintenance work.

[0122] The following describes the procedure by which a maintenance worker PB performs maintenance work on a septic tank for which reconciliation by a reconciliation worker PA has been completed, and registers the work in a septic tank management program. Here, a maintenance program built as a web application is used as one of the septic tank management programs. Note that, like the reconciliation terminal 2A used by the reconciliation worker PA, the maintenance terminal 2B used by the maintenance worker PB can also be a mobile terminal such as a general smartphone. In other words, there is no difference in hardware between the reconciliation terminal 2A used by the reconciliation worker PA and the work maintenance terminal 2B used by the maintenance worker PB. (Registration of maintenance worker PB)

[0123] Each maintenance worker PB registers the necessary worker information for each task in the worker database 50 in advance. The worker information includes the name of the maintenance worker PB, the affiliation (such as the name of the cleaning company or management company for the septic tank 1), and email address. The worker information can be registered by email or fax using a paper registration application form 140, as shown in FIG. 17. Alternatively, the worker information can be collected in the form of a web form with a structured format, as shown in FIG. 18. This method allows the URL for the web form registration destination to be sent to the maintenance terminal 2B via email, SMS, or the like, making it easy to distribute the worker information registration screen. Furthermore, when changing registered information, the maintenance worker PB's own application can be reflected directly, eliminating the need for manual input. An example of a web form for changing registered information is shown in FIG. 19. For such a web form, an existing service such as Google Forms (product or service name) can be used, or a dedicated registration page can be prepared. The information collected using the email address questionnaires shown in FIGS. 17 to 19 is registered in the worker database 40. (First authentication)

[0124] Furthermore, by periodically undergoing an authentication procedure for the septic tank management system 1000, access by unauthorized parties can be blocked, thereby improving security. A specific procedure for registering a maintenance worker PB will be described with reference to FIGS. 20 to 22. First, as shown in FIG. 20, on an email address input screen 150, the email address used by the maintenance worker PB is entered in an email address input field 151 and a send button 152 is pressed. This automatically sends a login screen guide email 160, as shown in FIG. 21, to the email address specified in the email address input field 151, and a link 161 to the login screen is displayed. Tapping the link 161 to the login screen jumps to a dedicated URL, which displays a worker registration screen 190, as shown in FIG. 24. The worker registration screen 190 displays a category display field 191, a work date and time display field 192, a worker name display field 194, an affiliation display field 193, and a reply button 195. When the worker registration screen 190 is accessed, authentication is automatically performed, and the information is sent to the server 30 and registered in the worker database 50. (Re-authentication)

[0125] The septic tank management system 1000 may also be configured to periodically request re-authentication from the maintenance terminal 2B. This requires the maintenance worker PB to undergo periodic re-authentication, thereby preventing unauthorized access and enhancing security. Re-authentication may be performed, for example, once every two weeks. Once re-authentication is performed, the worker remains logged in to the septic tank management system 1000 until the next re-authentication, maintaining an accessible session. Re-authentication may be performed by the maintenance worker PB periodically voluntarily accessing a predetermined URL. Alternatively, re-authentication may be performed by the server, which determines whether re-authentication is necessary when the worker accesses the septic tank management system 1000, such as by timing the user by scanning the QR code on the septic tank management sticker 10. In the latter case, each maintenance worker PB undergoes re-authentication as needed during their daily work, allowing them to continuously use the septic tank management system without having to worry about when to re-authenticate.

[0126] This re-authentication procedure can be the same as the initial authentication procedure described above. As an example, a procedure for re-authentication performed by maintenance worker PB in the process of reporting septic tank maintenance work will be described with reference to FIG. 23 and other figures. First, as shown in FIG. 23, a re-authentication screen 180 is displayed. Here, “Log in with email address 181” is selected as the re-authentication method. This changes to the email address input screen of FIG. 20, where an email address input field 151 is displayed. When maintenance worker PB enters a registered email address in email address input field 151, a login screen guide email 160 as shown in FIG. 21 is automatically sent to the email address. When maintenance worker PB taps link 161 to the login screen, worker registration screen 190 of FIG. 24 is displayed. Since the contents at the time of connection are displayed in each field, re-authentication is performed without the maintenance worker PB having to touch these fields. If re-authentication is approved, login using the maintenance terminal 2B is permitted.

[0127] As described above, the work of maintaining the septic tank 1 includes maintenance and inspection, cleaning, and legal inspection of the septic tank 1. In order to distinguish between these types of work on the septic tank management system 1000 side, email addresses are used. That is, a maintenance worker PB is registered for each of the maintenance and inspection, cleaning, and legal inspection of the septic tank 1, and the email address is used to distinguish whether the work is maintenance and inspection, cleaning, or legal inspection of the septic tank 1. In other words, a maintenance worker PB needs to be registered for each of the work of maintenance and inspection, cleaning, and legal inspection of the septic tank 1. (Maintenance work report screen 190)

[0128] After performing maintenance inspection, cleaning, and statutory inspection of the septic tank 1, the maintenance worker PB submits a work report at the installation site of the septic tank 1. This work report is made via the maintenance work report screen 190. The maintenance work recorded on the maintenance work report screen 190 is also registered and updated in the septic tank management database 40. Specifically, at the installation site of the septic tank 1, the worker reads the specific information, i.e., the QR code, on the septic tank management sticker 10 to jump to the URL of the maintenance work report screen 190 and submit the work report. (Septic Tank 1 Cleaning Report)

[0129] Here, the procedure for reporting the cleaning work performed on the septic tank 1 will be described with reference to FIGS. 24 to 26. First, the maintenance worker PB activates the camera of the maintenance terminal 2B and reads the QR code on the septic tank management sticker 10 attached near the septic tank 1. This causes a jump to the URL of a maintenance work report screen 190 for the corresponding septic tank 1. Here, as an example of the maintenance work report screen 190, the cleaning work report screen shown in FIG. 24 is displayed. The cleaning work report screen displays a septic tank maintenance work classification display field 191, a work date and time display field 192, an affiliation name display field 193, a worker name display field 194, and the like. In each field, information about the maintenance worker PB who operated the maintenance terminal 2B from which the access originated is acquired from information registered in advance in the worker database 50 based on the email address questionnaires of FIGS. 17 and 18, and is automatically entered. The maintenance worker PB checks each field and, if there are no problems, presses the reply button 195, which causes the report completion screen 210 to be displayed as shown in FIG. 25, and the details of the maintenance work are sent to the server 30 and registered in the septic tank management system 1000. In this way, the maintenance work report screen 190 displays the necessary information pre-entered, and the maintenance worker PB can make a report simply by pressing the reply button 195. Also, on the maintenance work report screen 190, editing of already entered items may be prohibited. This prevents input errors when reporting maintenance work, making it possible to reliably submit work reports. Also, if you want to edit already entered items, you can use the work report editing function described below.

[0130] The information is also registered in the septic tank management database 40. Specifically, as shown in the septic tank maintenance information list screen 220 in Fig. 26, the septic tank maintenance work performed by the maintenance worker PB is displayed as a list as registered information on the server 30 side. Here, information such as the record number, communication ID number, date and time, worker name, and affiliation (work company) is displayed as a list. The server 30 accesses the septic tank management database 40 and updates information such as the date of work performed by the maintenance worker PB, the worker name, and the management company name for each type of maintenance work, i.e., maintenance inspection, cleaning, and statutory inspection.

[0131] The maintenance work number sticker 65 is also used to register the maintenance work number on the server. Specifically, after the septic tank management work is completed, a new maintenance work number sticker 65 is taken out and affixed to the septic tank inspection form 60. In the example of FIG. 6, the maintenance work number sticker 65 is affixed to the left margin. Then, when the QR code in the code display field 14 of the septic tank management sticker 10 is read to report the septic tank management work, the maintenance work number sticker 65 is also read, and the maintenance work number is also registered on the server. In this way, the septic tank management work performed by the maintenance worker PB is registered on the server side. (Procedure for reporting work when out of communication range)

[0132] The above describes the procedure for reporting cleaning work in a data communication environment. However, cleaning work reports can also be submitted in a similar manner in an environment where data communication is unavailable. This procedure will be described with reference to FIGS. 27 to 30. First, the camera of the smartphone, which is the maintenance terminal 2B, is activated to capture an image of the septic tank management sticker 10. Next, the smartphone's camera uses its recognition function to extract information. Specifically, on the camera screen 230 in FIG. 27, the area designation icon 231 shown in the lower right is tapped to enable area designation as shown in FIG. 28. Then, the QR code portion of the code display field 14 of the septic tank management sticker 10 in the image is tapped. This selects the QR code, and the smartphone decodes the QR code and extracts the URL. In this state, work reports can be submitted by opening a web browser. Here, after the maintenance worker PB moves within a data communication range, he or she taps Open in Browser 232 as shown in FIG. 29 to display a maintenance work report screen 190, such as a cleaning report screen. As a result, the contents of each item are automatically entered as described above, and the work report is completed by tapping the reply button 195 as shown in Fig. 30. In this way, it is possible to make a work report without depending on the communication environment of the place where the septic tank 1 is installed.

[0133] In this way, the specific maintenance work performed by the maintenance worker PB is registered in the septic tank management system through the maintenance program and the server 30 by operating the maintenance terminal 2B. Specifically, information such as the work category of the maintenance work, the date and time the maintenance work was performed, the company name, the worker's name, and the septic tank number is stored in the maintenance work storage area 52. After a certain period of time has passed, the server 30 registers the information stored in the maintenance work storage area 52 in the septic tank management database 40 and updates it. The certain period of time for this update can be any timing, such as the day after the maintenance worker PB makes a report or several hours later. Alternatively, the server 30 may update the septic tank management database 40 simultaneously with the report. After the maintenance work is registered in the septic tank management database 40, the maintenance work storage area 52 is deleted. (Work report editing function)

[0134] Furthermore, if the maintenance worker PB submits a work report and some unforeseen circumstances arise, such as misreading the QR code or work being canceled, the work report can be edited or deleted. An example of such a procedure will be described with reference to FIGS. 31 to 34. First, open the report result list screen 240 to be edited.
