Description

Technical Field

[0001] The present disclosure relates to a septic tank management system, a sticker for septic tank management, a septic tank management device, a septic tank management method, a septic tank management program, a computer-readable recording medium, and a recording device.

Background Art

[0002] In order to purify domestic sewage and the like, septic tanks that treat sewage by utilizing the action of microorganisms are used. In such septic tanks, it is necessary to maintain an environment in which microorganisms can properly act in the tank, and it is required that a person perform regular maintenance and inspection work. Such work is entrusted to specialized contractors. And in each prefecture, a septic tank management ledger is created in the management department, and the history of maintenance and inspection work and the like are registered and managed in the septic tank management ledger.

[0003] However, each contractor manages the work individually, and some contractors manage it with a paper ledger, so it has been extremely difficult to grasp the maintenance management of each septic tank. That is, generally, the work performed by each contractor is sent to the management department of the prefecture. At the management department of each prefecture, based on the reports of each contractor, it is necessary to manually identify the corresponding septic tank from the septic tank management ledger and manually reflect what kind of work was done on which septic tank and when.

[0004] On the other hand, a septic tank management device has been proposed that claims to be able to properly manage everything from the installation of septic tanks to subsequent inspections, cleaning, statutory inspections, and decommissioning (Patent Document 1). According to this septic tank management device, as shown in Figure 35, a ledger database 92 that stores management information is updated and managed based on the status information of each septic tank transmitted from each septic tank 91. The management information includes ledger information that includes one of the following: 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 operation information based on operation information transmitted from each communication device 93, an abnormality processing unit that sends confirmation information to the administrator terminal when an abnormality is detected in each septic tank, and a maintenance information update processing unit that updates maintenance information based on maintenance work completion information. In addition, each septic tank 91 is equipped with a monitoring unit 94 that monitors its operating status.

[0005] However, as shown in Figure 35, this septic tank management device 90 requires the installation of a communication device 93 and a monitoring unit 94 in each septic tank 91, which presents problems in terms of time and cost. In particular, individually installing communication functions, etc., in all of the numerous septic tanks 91 is not very practical. [Prior art documents] [Patent Documents]

Another issue is to provide a septic tank management system, septic tank management stickers, a septic tank management device, a septic tank management method, a septic tank management program, a computer-readable recording medium, and a recording device that enable management without installing communication functions in each septic tank. The description of these objectives and issues in this disclosure does not preclude the existence of other objectives and issues. Furthermore, one aspect of this disclosure does not need to solve all of these issues. It is also possible to extract other issues from the description in the specification, drawings, and claims of this disclosure. Means for solving the issues and effects of the invention.

[0008] The septic tank management system according to Embodiment 1 of this disclosure is a septic tank management system for managing multiple septic tanks, comprising: a septic tank management database storing a septic tank number assigned to each septic tank in advance, the location or name of the manager of the septic tank, and septic tank maintenance information relating to the maintenance of the septic tank; a septic tank management sticker affixed near each septic tank, having 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, which is assigned separately 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, and matching the specific information displayed in the code display field of each septic tank management sticker. The system comprises a matching terminal for reading the communication ID and transmitting it to the server, a server for reading the specific information displayed in the code display field of the septic tank management sticker from the matching terminal and transmitting the communication ID, associating it with the septic tank number assigned to the communication ID, and storing it in the matching data storage area, and a maintenance terminal for reading the specific information displayed in the code display field included in the septic tank management sticker of each septic tank and transmitting it to the server after maintenance work for each septic tank has been performed by a maintenance worker, wherein the server is configured to reflect in the septic tank management database the maintenance work for the septic tank associated with the septic tank number, which is transmitted by reading the specific information displayed in the code display field of the septic tank management sticker transmitted from the maintenance terminal and associated with the communication ID. With the above configuration, maintenance work such as cleaning was performed individually on numerous septic tanks by numerous different businesses. Previously, this process was extremely cumbersome because it was done manually by relying on the septic tank number. However, by attaching a septic tank management sticker with a communication ID to each septic tank and reading the communication ID, the 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 simplifying the process of linking communication IDs.

[0009] Furthermore, the septic tank management system according to Embodiment 2 is configured to further include, for each septic tank, a septic tank inspection sheet containing the septic tank number of the septic tank and septic tank maintenance information relating to the maintenance of the septic tank. When the matching terminal transmits the communication ID to the server, it reads the septic tank number printed on the septic tank inspection sheet of the septic tank to which the communication ID is to be assigned, and transmits it 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 Embodiment 3, in any of the above embodiments, the septic tank inspection slip includes a septic tank number code which encodes the septic tank number, and when the matching terminal transmits the communication ID to the server, it reads the encoded septic tank number printed on the septic tank inspection slip of the septic tank to which the communication ID is to be assigned, and transmits it to the server, thereby associating the communication ID with the septic tank number and recording it in the matching data storage area. This makes it possible to prevent input errors of the septic tank number when matching the septic tank number with the communication ID.

[0011] Furthermore, the septic tank management system according to form 4 is a septic tank management system for managing multiple septic tanks, comprising: a septic tank management database storing a septic tank number assigned to each septic tank in advance, the location or name of the manager of the septic tank, and septic tank maintenance information relating to the maintenance of the septic tank; a septic tank management sticker affixed near each septic tank, having 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, which is assigned separately 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 in association with the communication ID included in the specific information displayed in the code display field; a matching terminal for a matching worker to read the specific information displayed in the code display field of each septic tank management sticker and transmit the communication ID to the server; and a matching data storage area for each septic tank. The system includes a maintenance terminal for reading the specific information displayed in the code display field included in the septic tank management sticker of the septic tank after the maintenance worker has performed the maintenance work, and transmitting the communication ID to the server; a maintenance work storage area for storing septic tank maintenance update information indicating the maintenance work for each septic tank together with the communication ID; and a server for recording the communication ID transmitted from the matching terminal in the maintenance work storage area together with the septic tank maintenance update information, and also accessing the septic tank management database, and by referring to the matching data storage area, identifying the septic tank number associated with the communication ID of the septic tank maintenance update information, and updating the septic tank maintenance information for the corresponding septic tank with the septic tank maintenance update information related to the maintenance work performed by the maintenance worker. The above configuration significantly reduces the effort required to record the results of maintenance work, such as cleaning and inspection, performed by multiple workers on numerous septic tanks in a septic tank management database.In particular, the previously cumbersome task of identifying which septic tank a worker performed work on can now be eliminated by reading specific information displayed on the septic tank management sticker. This information is then linked to the communication ID assigned to the sticker, and the septic tank number is referenced in the matching data storage area. As a result, the manual matching process that was previously required is eliminated, and the results of each worker's work can be smoothly reflected in the septic tank management database, enabling efficient recording and management of work. In this way, the workload of updating the septic tank management database is significantly reduced, and the digital transformation of septic tank management can be achieved.

[0048] Furthermore, the septic tank management program according to form 39, in any of the above forms, further includes a function that, after a maintenance worker performing maintenance work on a septic tank has performed maintenance work on the septic tank, 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 transmits the septic tank maintenance update management information related to the maintenance of the septic tank, along with the communication ID contained in the specific information, to the server, and the server receives the communication ID and septic tank maintenance update information transmitted from the matching terminal and records the maintenance work for each septic tank in a maintenance work storage area for storing the maintenance work along with the communication ID. The system enables a computer to perform the following functions: recording; accessing a septic tank management database for storing septic tank maintenance information related to the maintenance of each septic tank, including a septic tank number assigned to each septic tank in advance, the location or name of the manager of the septic tank, and the maintenance management information related to the septic tank; identifying the septic tank number associated with the communication ID of the septic tank maintenance management update information from the septic tank ledger database, which is registered by referring to the matching data storage area, and updating the septic tank maintenance information for the corresponding septic tank with the septic tank maintenance management update information performed by a maintenance worker who possesses the maintenance terminal.

[0049] Furthermore, the septic tank management program according to form 40 is a septic tank management program that manages multiple septic tanks, and has a septic tank management sticker attached nearby to a septic tank, the septic tank management sticker having a septic tank number display field that displays a unique septic tank number assigned to each septic tank, and a code display field that displays specific information including a pre-recorded arbitrary communication ID, which is assigned separately from the septic tank number, and after a maintenance worker has performed maintenance work on the septic tank, the maintenance worker uses their own maintenance terminal to read the specific information displayed in the code display field of the septic tank management sticker, and transmits septic tank maintenance update management information related to the maintenance of the septic tank, along with the communication ID included in the specific information, to the server, and the server uses the maintenance terminal This system enables a computer to perform the following functions: receiving the communication ID and septic tank maintenance update information transmitted from the system, recording the maintenance work for each septic tank in a maintenance work storage area for storing the maintenance work for each septic tank along with the communication ID; and a server accessing the septic tank management database, identifying the septic tank number associated with the communication ID of the septic tank maintenance update information from the septic tank ledger database, which is registered by referring to a matching data storage area where the communication ID and the septic tank number are recorded in association, and updating the septic tank maintenance information for the corresponding septic tank with the septic tank maintenance update information performed by a maintenance worker who possesses the maintenance terminal. This significantly reduces the labor required to record the results of cleaning and inspections performed by multiple workers on numerous septic tanks in the septic tank management database.

[0050] Furthermore, a computer-readable recording medium or storage device relating to form 41 stores a program relating to any of the above forms. The recording medium includes magnetic disks such as CD-ROM, CD-R, CD-RW, flexible disk, magnetic tape, MO, DVD-ROM, DVD-RAM, DVD-R, DVD+R, DVD-RW, DVD+RW, Blu-ray, UHD, HD DVD (AOD) (all registered trademarks or product names), optical disks, magneto-optical disks, semiconductor memory, and other media capable of storing programs. In addition to programs stored and distributed on the above recording medium, programs also include those distributed by download via network lines such as the Internet. Furthermore, storage devices include general-purpose or dedicated devices on which the above program is implemented in a state in which it can be executed in the form of software or firmware. Furthermore, each process and function included in the program may be executed by program software that can be executed on a computer, or each part of the processing may be implemented in a form in which program software and partial hardware modules that realize some elements of hardware are mixed.

[0052] The embodiments of this disclosure will be described below with reference to the drawings. However, the embodiments shown below are examples for concretizing the technical concept of this disclosure, and this disclosure is not limited to the following. Furthermore, this specification does not limit the members shown in the claims to the members of the embodiments. In particular, the dimensions, materials, shapes, relative arrangements, etc. of the components described in the embodiments are not intended to limit the scope of this disclosure to those, unless specifically stated otherwise, but are merely illustrative examples. Note that the size and positional relationships of the members shown in each drawing may be exaggerated for clarity of explanation. Furthermore, in the following description, the same name and reference numerals indicate the same or similar members, and detailed explanations are omitted as appropriate. Furthermore, each element constituting this disclosure may be configured such that multiple elements are made of the same member, with one member serving multiple elements, or conversely, the function of one member may be shared among multiple members. [Embodiment 1]

[0053] Figure 1 shows a septic tank management system 1000 according to Embodiment 1 of this disclosure. 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 consists of a 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 is equipped with a maintenance work storage area 52.

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

[0055] The server 30 and the worker database 50 constitute the septic tank management system 100. In the example shown in Figure 1, these server 30 and worker database 50 are implemented using a cloud computing service. The septic tank management system and septic tank management device may be configured using a dedicated server, or it may be configured using a rental server or a cloud server. For example, in the modified septic tank management system 3000 shown in Figure 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 all configured using a cloud server. (Septic tank 1)

[0056] Septic tank 1 treats wastewater by utilizing the action of microorganisms to purify human waste and domestic wastewater. In septic tank 1, it is necessary to maintain an environment in which microorganisms can properly function, and maintenance work is required to be carried out by humans.

[0057] Maintenance work includes periodic inspections, cleaning, and statutory inspections, and each of these maintenance tasks is outsourced to specialized companies. Inspections are performed by maintenance companies and include tasks such as adjusting the sludge in the septic tank and inspecting the blower. The frequency varies depending on the capacity and type of the septic tank, but is performed at least three times a year. Cleaning is performed by cleaning companies and involves removing sludge and scum generated during the process of microorganisms treating water in the septic tank, as well as cleaning and washing equipment and machinery to restore the function of the septic tank. The frequency varies depending on the capacity and type of the septic tank, but is performed at least once a year.

[0058] Furthermore, statutory inspections are conducted by statutory inspection businesses (designated inspection agencies). Statutory inspections consist of two parts: the Article 7 inspection, conducted 3 to 8 months after the start of use, to confirm whether the construction was carried out properly and whether the septic tank is performing its intended function; and the Article 11 inspection, conducted once a year. The Article 11 inspection confirms whether maintenance and cleaning are properly carried out and whether the septic tank's function is being maintained normally.

[0059] In this disclosure, the workers who perform these maintenance tasks are referred to as maintenance workers. On the other hand, the workers who perform the matching tasks described later are referred to as matching workers. In this disclosure, "worker" includes both maintenance workers and matching workers. Furthermore, among the worker terminals 2 operated by the workers, the worker terminal 2 operated by maintenance worker PB is referred to as maintenance terminal 2B, and the worker terminal 2 operated by matching worker PA is referred to as matching terminal 2A to distinguish them. These maintenance terminals 2B and matching terminals 2A can be general-purpose mobile devices such as smartphones, tablets, or PCs that are capable of network connectivity. In addition, when executing the maintenance program and matching program as the septic tank management program described later on the maintenance terminal 2B and 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 also be prepared, installed on each worker terminal, and executed.

[0060] To ensure that each stage of septic tank installation, maintenance, and decommissioning is tracked, prefectural management departments create and manage septic tank management ledgers, and the aforementioned maintenance, inspection, and cleaning history is registered in these ledgers.

[0061] However, each business operator that performs maintenance, cleaning, and statutory inspections manages their work individually, and some operators use paper ledgers, making it extremely difficult to track the maintenance 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 which septic tanks have received maintenance, cleaning, and statutory inspections, and when, based on the reports from each operator, and manually update the information in the septic tank management ledger. There are approximately 200,000 septic tanks in Tokushima Prefecture alone as of the end of March 2023, and the work required for their maintenance is extremely complex, making a more labor-saving and error-free management method urgently needed.

[0062] Furthermore, in recent disasters, including the Noto Peninsula earthquake at the beginning of 2024, the importance of securing toilets for the lives of evacuees has been highlighted. Many evacuees would prefer to stay at home rather than in an evacuation center if their toilets were usable. Therefore, from a disaster prevention perspective, it is necessary to establish a system that can quickly and efficiently inspect and manage septic tanks during disasters, such as checking whether they have been damaged by earthquakes.

[0063] Against this backdrop, the septic tank management system 1000 according to this embodiment aims to simplify the recording and updating work for maintenance and management, thereby promoting digital transformation in the management of the septic tank 1. Specifically, it simplifies the work of updating the septic tank management database 40, which is equivalent to the septic tank management ledger managed by local governments.

[0064] The septic tank management database 40 stores information related to each septic tank 1, including the septic tank number assigned to it in advance, the location where each septic tank 1 was installed, the name of the septic tank 1's manager, and septic tank maintenance information regarding the maintenance and management of each septic tank 1. Basically, this corresponds to the existing septic tank ledger system managed by each local government, for example, a prefecture. The septic tank maintenance information includes information such as the purpose of the septic tank's construction, the date of commencement of use, the name of the septic tank manufacturer, the contractor, the discharge destination, the type of septic tank, the treatment method, the target water quality for treatment, the number of people it can accommodate, and the amount of wastewater it can handle. (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 identification cards for affixing the stickers. The septic tank management sticker 10 is affixed near each septic tank 1. The septic tank management sticker 10 may be affixed directly to the septic tank, but generally septic tanks are installed in hard-to-reach places such as underground. Therefore, it is preferable to affix the septic tank management sticker 10 to an easily accessible and visible location near the septic tank 1. For example, outdoors near the septic tank 1, such as on a water tap post, a rain gutter, around the outlet of a blower installed outside the septic tank to supply oxygen to the septic tank, or at the entrance or front door of the building where the septic tank 1 is installed. Preferably, it is affixed to a flat surface under a roof, such as under an eaves, where it is not directly exposed to rain and wind. In this disclosure, for convenience, the septic tank management sticker 10 may be affixed to the septic tank 1, including affixing it 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 affixed outdoors and maintained for a long period of time even when exposed to rain and wind. This ensures that the specific information displayed in the code display area 14 of the septic tank management sticker 10 can be read for a long period of time, even in environments where it is exposed to the elements. For example, it may be made of a resin such as PET or polyester. Alternatively, the surface may be protected with a protective layer, such as by laminating it with translucent PET.

[0067] The back of the septic tank management sticker 10 has an adhesive layer, and as shown in Figure 4, multiple stickers are provided attached to a backing sheet. Each septic tank management sticker 10 is assigned a different communication ID. In the example in Figure 4, the communication IDs are nine digits numbered sequentially from top to bottom. On the backing sheet, a communication ID sticker displaying the communication ID is attached next to each septic tank management sticker. (Communication ID sticker)

[0068] It is preferable to affix the communication ID sticker to the septic tank inspection form 60 (Figure 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 section for affixing the communication ID sticker may be provided on the septic tank inspection form 60, or it may be affixed in an appropriate position outside the margin.

[0069] Returning to the description of the septic tank management sticker 10, as shown in Figure 4, each septic tank management sticker 10 includes a septic tank number display field 12 and a code display field 14. Additionally, the name or mark of the managing municipality may be added as needed. In the example in Figure 4, the words "Tokushima Prefecture Septic Tank Register" indicating that the septic tank is managed by Tokushima Prefecture are displayed along with the Tokushima Prefecture emblem. (Septic tank number display field 12)

[0070] The septic tank number display field 12 is a field for displaying the unique septic tank number assigned to septic tank 1. This field is initially left blank and is configured for the matching worker PA to fill in by hand. In other words, by 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, it is possible to avoid situations where errors such as mix-ups occur when attaching the septic tank management sticker 10 to septic tank 1. If septic tank management stickers with the septic tank management number printed on them were to be prepared in advance, it would be necessary to take the correct septic tank management sticker with you before leaving for the site, and furthermore, at the site, it would be necessary to find and attach the septic tank management sticker with the correct number, which would easily lead to errors such as mix-ups. In contrast, the septic tank management system 1000 according to this embodiment allows any septic tank management sticker 10 to be used, and by handwriting the septic tank number of the septic tank 1 when attaching it, the work can be simplified and the occurrence of errors can be greatly reduced. (Code display field 14)

[0071] The code display field 14 is a field that displays specific information, including a pre-recorded arbitrary communication ID. The communication ID plays a role in identifying septic tank 1 when communicating with the worker terminal 2, server 30, etc. In the example in Figure 4, the communication ID is a 9-digit number, but it is not limited to this; the characters used are not limited to numbers and may include English letters, symbols, etc., and the number of digits may also be increased or decreased. Furthermore, 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 septic tank 1.

[0072] The communication ID is inherently independent of the septic tank number. That is, although it is statistically possible for the numbers to coincide by chance, the communication ID basically exists as an independent number assigned separately from the septic tank number. Furthermore, the matching operator PA can assign any communication ID, that is, any septic tank management sticker, to any septic tank number. As a result, since the septic tank can be identified using the communication ID in communication using the operator terminal 2, manual identification is unnecessary, resulting in a septic tank management system that is extremely easy to manage. In addition, although the addition of a communication ID separate from the septic tank number necessitates a new matching process to link the communication ID to the septic tank number, this process can be easily performed. Moreover, once the matching process is performed, all subsequent work can be handled using the communication ID, increasing convenience. In addition, if the septic tank management sticker deteriorates or is damaged, it can be replaced with a new septic tank management sticker and the new communication ID can be re-matched, allowing the previous records to be carried over and the septic tank management system to be used continuously. (Specific information)

[0073] The specific information displayed in the code display field 14 includes URL information for accessing server 30 and a string for initial input of the communication ID. Initial input means that the communication ID is identified at the same time as accessing the URL. This allows the worker terminal 2 to read the specific information, access the corresponding URL on server 30, and log in with the communication ID identified.

[0074] Furthermore, specific information can be represented using a code that encodes a string of characters representing that specific information. This allows for the recording of information such as communication IDs in the code, reducing errors during reading by the worker terminal 2 and enabling smooth and quick input of specific information. In addition to one-dimensional codes such as barcodes, two-dimensional codes such as QR codes (registered trademark) can also be used. QR codes (registered trademark) are particularly preferred due to their fast response speed and high versatility, as they can be easily read by general-purpose smartphones and tablets. However, this disclosure does not limit the code to QR codes (registered trademark), and other two-dimensional codes can also be used, such as matrix-type codes (matrix symbol systems) like DataMatrix and VeriCode, or stack-type codes (multi-row symbol systems) like PDF417 and CODE49. Alternatively, numbers or strings of characters can be directly used as codes instead of codes that require encoding. In this case, the code can be read using OCR. Furthermore, instead of these printed codes, RFID embedded in stickers can be used as codes. In this case, septic tank management stickers can be used as IC tags. Thus, the term "septic tank management sticker" does not necessarily have to be in the form of a sticker; it is used to include not only the name but also tag-like or plate-like forms.

[0075] Furthermore, it is preferable that the septic tank management sticker 10 does not contain personal information. Only the septic tank number is displayed, and no personally identifiable information such as address or name is displayed, nor is it included in specific identification information. This prevents personal information from being leaked from the affixed septic tank management sticker 10. In addition, even if information is leaked on the cloud server side, the leakage of personal information can be minimized, thereby enhancing security.

[0076] Furthermore, 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 repeated. 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 and associating the septic tank number displayed in the septic tank number display field 12 of each septic tank management sticker 10 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 result of the matching is stored in this matching data storage area. A local file server or database can be used for such a matching data storage area 20. In the example in 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 place and connected to the network separately. Note that the file server function can also use a cloud service as shown in Figure 3, but considering the security risks such as information leakage, it is preferable not to upload 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 was installed, the name of the administrator who manages the septic tank, and septic tank maintenance information related to the maintenance and management of the septic tank. Such a septic tank management database can utilize the existing septic tank ledger system held by each local government.

[0079] Furthermore, the septic tank management database does not contain communication ID information. Instead, it updates the septic tank maintenance information by referring to the matching data storage area and using the septic tank maintenance work category of the maintenance worker PB, which is transmitted along with the communication ID. However, the septic tank management database 40 may be given a communication ID after the matching work is completed, 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 names of maintenance workers PB who use each maintenance terminal 2B. The worker database registers the names, email addresses, affiliations (management company names), and types of septic tank maintenance work (work categories) that maintenance workers PB are responsible for using maintenance terminal 2B. Here, using the email address as a search key, it is possible to retrieve information about the maintenance worker PB who operated the maintenance terminal 2B associated with that email address, including the name of the maintenance worker PB, affiliation, and type of maintenance work.

[0081] In this example, the system is configured to identify worker information from an email address in the worker database. However, it goes without saying that the system is not limited to using email addresses as the search key. For example, it is also possible to configure the system to identify worker information using other worker information, such as the name or ID number of maintenance workers. Furthermore, the term "worker" here refers primarily to maintenance workers who perform maintenance work on septic tanks. In other words, matching workers who perform matching work are generally not included. However, if a matching worker also serves as a maintenance worker, they may be included in the worker database.

[0082] In the example shown in Figure 5, the maintenance worker PB who performs the statutory inspection is also responsible for matching the data. In other words, the maintenance worker PB who performs the statutory inspection also serves as the matching worker PA. By having the maintenance worker who performs the statutory inspection also serve as the matching worker PA, when performing the mandatory statutory inspection at each septic tank, the matching work can be carried out sequentially along with the statutory inspection by having the septic tank management sticker affixed and matching the communication ID with the septic tank number. This allows for the efficient promotion of the septic tank management system.

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

[0084] The maintenance work storage area 52 is an area for storing maintenance work related to each septic tank, along with a communication ID. After a maintenance worker PB performs maintenance work on each septic tank, the maintenance worker PB reports this maintenance work to the septic tank management system, and the maintenance work is recorded in the maintenance work storage area 52 as septic tank maintenance update information along with the communication ID. Preferably, a cloud server can be used for such a maintenance work storage area 52. In the example in Figure 1, the maintenance work storage area 52 is implemented as part of the server 30. However, the maintenance work storage area 52 can be any form, such as a file server or a database.

[0085] The maintenance work recorded in the maintenance work storage area 52 includes information that identifies the septic tank, such as the communication ID, the name and affiliation of the maintenance worker PB who performed the maintenance work, the date and time the maintenance work was performed, and the work category. In the maintenance work storage 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 and the location of the septic tank is not included in the maintenance work storage area 52. This reduces the risk of information related to the identification of general users being leaked to the outside even if information is leaked from the cloud server.

[0086] Furthermore, when maintenance worker PB reports the maintenance work they have performed to the septic tank management system server 30 via the maintenance terminal 2B, the server 30 registers this septic tank maintenance update information along with the communication ID in the maintenance work storage area 52. Subsequently, the server 30 further registers the septic tank maintenance update information registered in the maintenance work storage area 52 into the septic tank management database 40. At this time, the matching data storage area 20 is referenced by the server 30 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 storage area 52 is reflected in the corresponding septic tank in the septic tank management database 40.

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

[0088] When the septic tank management system is in operation, server 30 receives a communication ID transmitted 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, it updates the septic tank maintenance information for the corresponding septic tank 1 with the maintenance work performed on that septic tank by the maintenance worker PB who owns the maintenance terminal 2B. This allows reports of septic tank maintenance work performed from the maintenance terminal 2B to be quickly reflected in the septic tank management database.

[0089] On the other hand, when the septic tank management system is being built, that is, during the matching process, the server associates the communication ID transmitted from the matching 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 that are individually assigned to many septic tanks, and in subsequent operations, the septic tank can be identified by the communication ID, resulting in the advantage of reducing the effort required to update the septic tank management database. In particular, by allowing the association of any communication ID rather than using pre-assigned numbers such as septic tank numbers, any septic tank management sticker can be used, reducing the likelihood of errors such as incorrect sticker application, improving usability and convenience on-site, and reducing the effort required for tedious tasks and error verification, thereby promoting the digital transformation 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 with file server functionality to construct the server 30 and the matching data storage area 20, the advantage of being able to construct the septic tank management system 1000 at a low cost can be obtained. (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., a matching worker PA or a maintenance worker PB. It can utilize small network-connected information devices such as smartphones, tablets, or laptop computers. Smartphones with camera functions are particularly preferred as they can read codes and communicate data.

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

[0093] In this way, the process of recording the results of cleaning and inspections performed by multiple maintenance workers PB on numerous septic tanks 1 in the septic tank management database 40 can be significantly streamlined. In particular, the previously cumbersome process of identifying which septic tank 1 each maintenance worker PB worked on can now be achieved by reading the specific information displayed on the septic tank management sticker 10 and referencing the septic tank number linked to this communication ID in the matching data storage area 20. As a result, the matching process that was previously done manually is no longer necessary, and the results of each maintenance worker PB's work can be smoothly reflected in the septic tank management database 40, enabling the recording and management of work. In this way, the update process for the septic tank management database 40 is significantly streamlined, enabling the digital transformation of septic tank management. (Settings for the septic tank management system)

[0094] Figure 5 shows a block diagram illustrating the setup and operation flow of the septic tank management system 1000. As shown in this diagram, when the septic tank management system 1000 is started up, a matching worker PA performs a matching operation between the communication ID and the septic tank number as a necessary setup task. Here, the matching worker PA goes to the installation site of septic tank 1 with a septic tank management sticker 10 and a septic tank inspection form 60 that details the relevant septic tank. The worker here refers to the matching worker who performs the matching operation between the septic tank number and the communication ID. Typically, the matching worker is an employee of the company operating the septic tank management system. In addition, a statutory inspection of the septic tank may be conducted at the same time as the matching operation. (Septic Tank Inspection Form 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 that records information such as the septic tank number, the address of the installation location, and the name of the person responsible for management for each septic tank. It is also called a field notebook and is generally created by the inspection agency designated by the prefectural governor that inspects each septic tank. In the second row from the top left of the septic tank inspection form 60, there is a septic tank number display field 62 where the numerical value of the septic tank number is displayed. In the upper right, a septic tank number barcode 61 is displayed as a septic tank number code, which is a coded representation of this septic tank number. By reading the septic tank number barcode 61, the septic tank number can be entered accurately. Note that a code other than a barcode, such as a two-dimensional code, may also be used for the septic tank number 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 form 60 contains information regarding the maintenance and management of the septic tank. This section includes information regarding statutory inspections as part of the maintenance work. (Maintenance work number sticker 65)

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

[0098] Each time maintenance worker PB performs septic tank maintenance work, they prepare a new maintenance work number sticker 65 and, preferably as shown in Figure 6, affix it to the sticker area on the septic tank inspection form 60. The sticker number on this maintenance work number sticker 65 is then read by the maintenance terminal 2B and registered on the server. For example, after completing septic tank maintenance work, when reporting the septic tank maintenance work by reading the QR code in the code display area 14 of the septic tank maintenance sticker 10, the maintenance work number sticker 65 is also read and the maintenance work number is registered on the server. This registers the septic tank maintenance work performed by maintenance worker PB on the server.

[0099] These maintenance work number stickers 65 can be prepared in multiple copies with the same sticker number. For example, three maintenance work number stickers 65 for each sticker number can be bound together, with one sticker affixed to the septic tank inspection form 60 when reporting maintenance work. The remaining two stickers can be affixed to sample bottles containing liquid samples taken from the septic tank, or to copies of receipts issued to septic tank managers when making cash payments, thereby facilitating the management of each septic tank maintenance task.

[0100] Furthermore, a new maintenance work number sticker 65 is added for each maintenance work performed. For example, if regular maintenance work is performed on the same septic tank, a new maintenance work number sticker 65 with a new number is affixed to the septic tank inspection slip 60 issued for each maintenance work. This allows for the individual identification of each septic tank maintenance work performed on the same septic tank. Figure 6 shows an example of a statutory inspection as a septic tank maintenance work. (Butt joint work)

[0101] The following describes the procedure by which a matching worker PA performs matching work, 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 due to the absence of a person in charge or inability to make a decision, an explanatory leaflet like Figure 8, explaining the necessity of affixing a septic tank management sticker, will be distributed by hand or by placing it in a mailbox (Step S2).

[0103] Next, the matching worker PA writes the septic tank number by hand in the septic tank number display field 12, as shown in Figure 9 (Step S3). The septic tank number is confirmed by referring to the septic tank inspection form 60 shown in Figure 6, which was brought by the matching worker PA. When writing the septic tank number by hand, a writing instrument using weather-resistant ink should be used. For example, an oil-based pen using oil-based ink that is difficult to erase should be used. In this embodiment, Bigman Strong Paint Marker and Mitsubishi Pencil Paint Marker (both product names) are used. This ensures that the septic tank number will not easily fade even if the septic tank management sticker 10 is left exposed to the elements for about 5 years.

[0104] Then, a septic tank management sticker with the septic tank number written on it, as shown in Figure 9, is affixed near the septic tank (step S4). For example, if the direct consent of the septic tank manager is obtained, it is affixed in a conspicuous place such as the entrance of the building. This makes it easier to confirm that it is 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 inspections or cleaning. On the other hand, if the direct consent of the septic tank manager cannot be obtained (typically when the manager is absent when visiting the house where the septic tank is installed), the septic tank management sticker is affixed near the septic tank. For example, it is affixed near the inspection certificate of septic tank 1. In addition, an explanatory document (such as an explanatory leaflet titled "Notice from Tokushima Prefecture") informing the resident that the septic tank maintenance sticker has been affixed is received and placed in the mailbox. In either case, it is preferable to affix the septic tank management sticker 10 to a flat and smooth surface so that the code displayed on it can be read reliably. Furthermore, the sticker should be affixed in a way that it does not overlap with other stickers, such as inspection certificates, gas company stickers, or broadcasting station stickers.

[0105] It is preferable that the matching worker PA handwrites the septic tank number in the septic tank number display field 12 of the septic tank management sticker 10 immediately before attaching the sticker. This is especially true when attaching the septic tank management sticker 10 to a curved surface such as a pipe, as it is difficult to write in the septic tank number display field 12 after attachment. However, if the surface to which the sticker is 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 operator PA also links the septic tank number with the communication ID on the septic tank management sticker 10 that has been attached (step S5). Furthermore, as shown in Figure 9, the septic tank number is written on it, and after attaching the septic tank management sticker 10 to the septic tank, a photograph of the septic tank management sticker 10 in its attached state is taken (step S6). The camera of the matching terminal 2A, which is a smartphone, is used to take the photograph. This image is sent to the server 30. The septic tank management database 40 then saves the image of the septic tank management sticker 10 that has actually been attached and has the septic tank number written on it, so that at a later date, it is possible to check for errors in the handwritten septic tank number, check the communication ID, and recover from any errors that may have occurred during matching (correcting errors or rematching). It is also possible to check which part the septic tank management sticker 10 was attached to. Furthermore, if the matching operator PA forgets to perform the matching work at the site, it is possible to perform the matching by reading the QR code of specific information contained in the image without having to go back to the site. To take a photograph, for example, press the "Take a photo" button 128 on the data registration screen 120 shown in Figure 15, which will be described later.

[0107] The above steps—distributing the explanatory leaflet (Step S2), filling in the septic tank number (Step S3), attaching the septic tank management sticker (Step S4), linking the septic tank number with the communication ID (Step S5), and taking a photograph of the septic tank management sticker 10 (Step S6)—may be carried out in any order as appropriate.

[0108] The matching operation in Step S5, performed by the matching operator PA, that is, the matching of the septic tank number and the communication ID, is carried out using the septic tank management program. The septic tank management program can be a dedicated application installed on the matching terminal 2A held by the matching operator 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's kintone (service name), but it goes without saying that other cloud services can also be used. The procedure for the matching operation using the specific matching program will be explained with reference to Figures 10 to 14. (Program for matching)

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

[0110] The septic tank search screen 110 includes a septic tank number input field 112, a barcode reading button 114, and a search button 116. The septic tank number can be directly entered into the septic tank number input field 112. Here, the barcode reading button 114 is pressed. This activates the camera, enabling barcode reading. At this point, the septic tank inspection form 60 shown in Figure 6 is taken out, and the septic tank number barcode 61 displayed in the upper right corner of the septic tank inspection form 60 is read. As a result, the decoded septic tank number obtained from the read septic tank number barcode 61 is automatically entered into the septic tank number input field 112, as shown in Figure 11. The matching operator 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, which is 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 Figure 12 is displayed. In this way, instead of manually entering the septic tank number, the septic tank number printed on the septic tank inspection sheet such as a field notebook is read by the matching worker PA using the matching terminal 2A and entered, thereby preventing input errors of the septic tank number and ensuring that the matching work between the septic tank number and the communication ID is performed reliably. Also, as mentioned above, a photograph of the septic tank management sticker 10 affixed near the septic tank is taken. Specifically, on the data registration screen 120 in Figure 15, the "Take a photo" button 128 is pressed to take the image. (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 septic tank 1 is installed, a communication ID input field (QR code) 123, and a QR code reading button 124. When the QR code reading button 124 is pressed, the camera is activated, and the QR code can be read. Here, the QR code displayed in the code display field 14 of the septic tank management sticker 10 shown in Figure 9 is read. As a result, the communication ID decoded from the read QR code is automatically entered into the communication ID input field 123 as shown in Figure 13. In this state, the matching worker PA scrolls through the data registration screen 120 and presses the result data transmission button 125 as shown in Figure 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 worker PA performs these steps at the site where septic tank 1 is installed. Then, after returning to the office, a daily report is created and registered, completing the reconciliation process.

[0112] The above describes an example of matching septic tank numbers and communication IDs by performing data communication using the matching terminal 2A. This method assumes that data communication is possible in the environment. However, in some locations, such as mountainous areas or remote areas, there may be no communication range, the radio waves may not be received well, or the communication may be unstable. In addition, data communication may be temporarily impossible due to communication failures, etc. In such cases, as described above, the septic tank management sticker 10 affixed near the septic tank is photographed with a smartphone camera at the site. Then, the matching worker PA moves away from the site and, once within the communication range, performs the registration work using the image of the photograph taken. Specifically, as shown in Figure 15, the data registration screen 120 is displayed and the photograph taken is read by pressing the photo library button 126. Here, as shown in Figure 16, with the image of the septic tank management sticker 10 that was photographed displayed on the image attachment screen 130, the image transmission button 132 is pressed to send this image to the matching data storage area 20, and matching is performed using this photograph. This makes it possible to match the septic tank number with the communication ID, regardless of the radio wave conditions at the septic tank's installation location.

[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 beforehand, 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 stickers with the septic tank number printed on them beforehand, it is possible to save the trouble of searching for the sticker with the correct septic tank number, prevent errors such as misidentifying septic tank numbers, and improve convenience.

[0114] If stickers with QR codes that directly encode the septic tank numbers were created, the matching process would be unnecessary. However, in this case, the QR code stickers would need to be printed on-site. This would require each worker to have a printer with communication capabilities, and the workers would have to carry these printers with them to print on-site, resulting in significant equipment investment and considerable effort.

[0115] On the other hand, it is also possible to print stickers with QR codes that encode the septic tank number in advance and carry them to the site. However, in this case, it is necessary to find the sticker corresponding to the septic tank number of the site to be visited and prepare it before the visit, and at the site, it is necessary to find the necessary sticker from among the multiple stickers carried, which is a cumbersome process. In addition, mistakes such as mixing up stickers or applying them incorrectly may occur.

[0116] In contrast, the septic tank management system 1000 according to this embodiment allows any septic tank management sticker 10 to be affixed at the site, and a matching operation is performed against the communication ID assigned to the affixed septic tank management sticker 10, resulting in extremely high work efficiency. Furthermore, by having the septic tank number handwritten on the sticker at the site, errors such as incorrectly affixing the septic tank management sticker 10 are prevented. In addition, the septic tank number on the septic tank management sticker 10 can be checked after it has been written, so any errors in writing can be checked.

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

[0118] Furthermore, by not placing the matching data storage area 20, which holds the septic tank number, on the cloud, the risk of leakage of personal information can be reduced. The matching data storage area 20 is linked to the septic tank management database 40. The matching worker PA transmits the communication ID encoded in a QR code and the septic tank number from the matching terminal 2A, and stores them in the matching database. Also, 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 association information is recorded in the septic tank management database 40. After matching, information from the maintenance terminal 2B, etc., is input to the server 30. The server 30 registers septic tank maintenance information from 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 regularly, such as annually. During these inspections, if the septic tank number on the septic tank management sticker 10 has faded or disappeared due to aging, the matching worker PA will rewrite the septic tank number. If the septic tank management sticker 10 is severely deteriorated, a new septic tank management sticker 10 will be affixed and the matching process will be repeated. This links a new communication ID 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. (Maintenance work for septic tanks)

[0120] On the other hand, maintenance workers (PB) who perform maintenance work on septic tanks are generally different from matching workers (PA) who perform matching work. Typically, matching workers (PA) are employees of the company that operates the septic tank management system. Furthermore, maintenance workers (PB) who perform maintenance work on septic tanks, such as maintenance inspections, cleaning, and statutory inspections, are employees of various businesses that specialize in these tasks, and are usually employees of external contractors different from the system operating company. In this disclosure, these maintenance workers (PB) are distinguished by pre-registering each maintenance worker (PB). Specifically, their email addresses are used to distinguish whether their assigned work is matching, septic tank maintenance 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 among themselves to perform maintenance on multiple septic tanks. Specifically, it is assumed that multiple maintenance workers belonging to different companies will share the maintenance work on various septic tanks. In addition, in the example of this disclosure, it is assumed that the matching worker who performs the matching work and the maintenance worker who performs the septic tank maintenance work are different people, but the same person may perform both. In this disclosure, the statutory inspection, which is part of the maintenance work, is performed by the matching worker PA. That is, as shown in Figure 5, the matching worker PA also serves as the maintenance worker PB, who is responsible for the statutory inspection, which is one of the maintenance tasks.

[0122] The following describes the procedure by which maintenance worker PB performs maintenance work on septic tanks that have already been matched by matching worker PA, and registers the information in the septic tank management program. Here, a maintenance program built as a web application is used as one of the septic tank management programs. The maintenance terminal 2B used by maintenance worker PB can be a general-purpose mobile device such as a smartphone, just like the matching terminal 2A used by matching worker PA. In other words, there is no hardware difference between the matching terminal 2A used by matching worker PA and the maintenance terminal 2B used by maintenance worker PB. (Registration of maintenance workers PB)

[0123] Each maintenance worker PB registers the necessary worker information for each work category in the worker database 50 in advance. Worker information includes the maintenance worker PB's name, affiliation (name of the cleaning company for septic tank 1, name of the management company, etc.), and email address. Worker information can be registered using a paper registration application form 140, such as the one shown in Figure 17, via email or fax. Alternatively, worker information may be collected using a web form with a structured format, as shown in Figure 18. With this method, the URL of the web form can be sent to the maintenance terminal 2B via email or SMS, making it easy to distribute the worker information registration screen. Furthermore, changing registered information can be done by simply reflecting the maintenance worker PB's own application, saving time on input. An example of a web form for changing registered information is shown in Figure 19. For such web forms, existing services such as Google Forms (product or service name) may be used, or a dedicated registration page may be prepared. The information collected using these email address survey forms in Figures 17 to 19 is registered in the worker database 40. (Initial Authentication)

[0124] Furthermore, by periodically performing authentication procedures with the septic tank management system 1000, access by unauthorized persons can be blocked, thereby improving security. The specific procedure for registering maintenance workers PB will be explained with reference to Figures 20 and 22. First, as shown in Figure 20, on the email address input screen 150, the email address used by maintenance workers PB is entered in the email address input field 151 and the send button 152 is pressed. As a result, a login screen guidance email 160, as shown in Figure 21, is automatically sent to the email address specified in the email address input field 151, and a link to the login screen 161 is displayed. By tapping the link to the login screen 161, the user is redirected to a dedicated URL, and the worker registration screen 190 shown in Figure 24 is displayed. 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 connected to the worker registration screen 190, authentication is performed automatically, and the information is sent to the server 30 and registered in the worker database 50. (Re-authentication Office)

[0125] The septic tank management system 1000 may also be configured to periodically request re-authentication from the maintenance terminal 2B. This ensures that maintenance workers PB undergo periodic re-authentication, eliminating unauthorized access and enhancing security. Re-authentication may be performed, for example, once every two weeks. Once re-authenticated, the user remains logged into the septic tank management system 1000 and maintains an accessible session until the next re-authentication period. Re-authentication may also be initiated by maintenance workers PB voluntarily accessing a designated URL periodically, or the server may determine whether re-authentication is necessary at the time of access to the septic tank management system 1000, such as by scanning the QR code on the septic tank management sticker 10. With the latter method, each maintenance worker PB undergoes re-authentication as appropriate during their daily work, allowing them to continuously use the septic tank management system without being conscious of the re-authentication schedule.

[0126] Such re-authentication procedures can utilize the same procedures as the initial authentication described above. As an example, the procedure for re-authentication performed by a maintenance worker PB during the process of reporting maintenance work on a septic tank will be explained with reference to Figure 23, etc. First, as shown in Figure 23, the re-authentication screen 180 is displayed. Here, as the method of re-authentication, select Login with email address 181. Then, the email address input screen shown in Figure 20 appears, and the email address input field 151 is displayed. When the maintenance worker PB enters their registered email address in the email address input field 151, a login screen guidance email 160 as shown in Figure 21 is automatically sent to that email address. When the maintenance worker PB taps the link to the login screen 161, the worker registration screen 190 shown in Figure 24 is displayed. Since the contents at the time of connection are displayed in each item, the maintenance worker PB does not need to touch these to perform re-authentication. Once re-authentication is approved, login using the maintenance terminal 2B is permitted.

[0127] As mentioned above, the maintenance work for septic tank 1 includes maintenance inspections, cleaning, and statutory inspections. To distinguish between these types of work, the septic tank management system 1000 uses email addresses. Specifically, a maintenance worker PB is registered for each of the maintenance inspections, cleaning, and statutory inspections of septic tank 1, and this email address is used to distinguish between these three types of work. In other words, a maintenance worker PB needs to be registered for each of the maintenance inspections, cleaning, and statutory inspections of septic tank 1. (Maintenance work report screen 190)

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

[0129] Here, the procedure for submitting a cleaning report when cleaning work is performed on septic tank 1 will be explained with reference to Figures 24 to 26. First, maintenance worker PB activates the camera on the maintenance terminal 2B and reads the QR code on the septic tank management sticker 10 affixed near septic tank 1. This jumps to the URL of the 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 Figure 24 is displayed. The cleaning work report screen displays fields such as the classification of the septic tank maintenance work 191, the work date and time 192, the name of the affiliated company 193, and the worker's name 194. Each item is automatically entered based on the email address of the accessing maintenance terminal 2B, and the information of the maintenance worker PB who operated the maintenance terminal 2B is obtained from information registered in the worker database 50 based on the email address survey form shown in Figures 17 and 18. The maintenance worker PB checks each field, and if there are no problems, presses the answer button 195. As shown in Figure 25, the report completion screen 210 is displayed, 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 is displayed with the necessary information pre-filled, and the maintenance worker PB can submit the report simply by pressing the answer button 195. Furthermore, editing of entered items may be disabled on the maintenance work report screen 190. This prevents input errors when reporting maintenance work and ensures that work reports are submitted reliably. If it is necessary to edit entered items, the work report editing function described later can be used.

[0130] Furthermore, the information is registered in the septic tank management database 40. Specifically, as shown in the septic tank maintenance information list screen 220 in Figure 26, the server 30 displays a list of septic tank maintenance work performed by maintenance worker PB. Here, information such as record number, communication ID number, date and time, worker name, and affiliated company is displayed. The server 30 accesses the septic tank management database 40 and updates information such as the work date, worker name, and management company name performed by maintenance worker PB for each type of maintenance work, namely maintenance inspection, cleaning, and statutory inspection.

[0131] Furthermore, the maintenance work number sticker 65 is used to register the maintenance work number on the server. Specifically, after the completion of the septic tank maintenance work, a new maintenance work number sticker 65 is taken out and affixed to the septic tank inspection form 60. In the example in Figure 6, the maintenance work number sticker 65 is affixed to the left margin. When reporting the septic tank maintenance work by reading the QR code in the code display field 14 of the septic tank management sticker 10, the maintenance work number sticker 65 is also read and the corresponding maintenance work number is registered on the server. This registers the septic tank maintenance work performed by the maintenance worker PB on the server side. (Procedure for reporting work in areas outside of communication range)

[0132] The above describes the procedure for reporting cleaning work in an environment where data communication is possible. However, the same procedure can be followed even in environments where data communication is not possible. This procedure will be explained with reference to Figures 27 to 30. First, the camera of the smartphone, which is the maintenance terminal 2B, is activated and an image of the septic tank management sticker 10 is taken. Next, the smartphone's camera uses its recognition function to extract information. Specifically, on the camera screen 230 in Figure 27, the area selection icon 231 shown in the lower right is tapped to enable area selection as shown in Figure 28, and then the QR code portion of the code display field 14 on the septic tank management sticker 10 in the image is tapped. This selects the QR code, and the smartphone decrypts the QR code to extract the URL. At this point, the work report can be submitted by opening a web browser. Here, after the maintenance worker PB moves into an area where data communication is possible, the browser 232 is opened as shown in Figure 29 to display the maintenance work report screen 190, such as the cleaning report screen. As a result, the contents of each item are automatically entered as described above, so tap the answer button 195 as shown in Figure 30 to complete the work report. In this way, it becomes possible to submit a work report regardless of the communication environment at the location where the septic tank 1 is installed.

[0133] In this way, the specific maintenance work performed by maintenance worker PB is registered in the septic tank management system via the maintenance program and server 30 by operating the maintenance terminal 2B. Specifically, the maintenance work storage area 52 stores 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. After a certain period of time, the server 30 registers and updates the information stored in the maintenance work storage area 52 in the septic tank management database 40. This update period can be any time, for example, the day after maintenance worker PB makes the report, or a few hours later. Alternatively, the server 30 may update the septic tank management database 40 simultaneously with the report. The maintenance work storage area 52 is deleted after the maintenance work is registered in the septic tank management database 40. (Work report editing function)

[0134] Furthermore, if any circumstances arise after a maintenance worker PB has submitted a work report, such as a misreading of the QR code or the cancellation of work, the work report can be edited or deleted. An example of such a procedure is explained with reference to Figures 31 to 34. First, open the report result list screen 240 to be edited. Specifically, on the maintenance work report screen 190 in Figure 24 or the report completion screen 210 in Figure 25, tapping the "Report Result List Here" link 196, the "Report Contents Here" link 211, etc. will display the report result list screen 240 shown in Figure 31. On this report result list screen 240, select the item you want to edit or delete. For example, if you want to delete the report result in the second row from the top in Figure 31, tap the edit icon 241 for the corresponding report result. This will display the report result editing screen 250 as shown in Figure 32. On the report result editing screen 250, tapping the edit button 251 will bring up the maintenance work report screen 190 where you can input the work report, as shown in Figure 33. In this state, as shown in Figure 34, by turning on the delete checkbox in the delete flag column 197 and tapping the answer button 195, the corresponding work report will be deleted, and a delete flag will be displayed next to the corresponding facility in the list table in Figure 26. Also, when accessing the septic tank management database 40, the information for the deleted item will not be updated.

[0135] Note that inputting or changing items is prohibited in the screens shown in Figures 33 and 34. However, it is possible to make the system editable so that maintenance workers (PB) can input and edit items as part of the work report editing function. For example, a maintenance worker (PB) who performed cleaning could select the results of the septic tank inspection and water quality evaluation from a list of options.
