Description

The present invention relates to a device for detecting an abnormality in the maintenance status of a septic tank. More specifically, the present invention centrally manages maintenance information of a septic tank and automatically evaluates the maintenance status based on the information. It relates to a device for promptly detecting an abnormality in the operation status and enabling more accurate maintenance and management of septic tank equipment and water quality maintenance.

In large cities, sewage treatment systems equipped with large-scale sewers have been developed as sewage treatment systems from receiving sewage discharged from buildings and facilities to treating and draining it. On the other hand, in areas where buildings and facilities are dispersed, it is difficult to install a large-scale sewerage system in terms of costs. Therefore, decentralized septic tanks are often used in these areas. Septic tanks play an important social role in preventing environmental pollution.

Septic tanks used in private houses and local facilities have various equipment and equipment configurations depending on the processing capacity and treatment content, and even septic tanks of similar scale have different equipment and equipment manufacturers. In fact, each septic tank has a different configuration. Conventional septic tanks are manufactured in accordance with the structural standards stipulated by laws and regulations, but new septic tanks newly installed in recent years are manufactured to comply with the performance standards stipulated by laws and regulations, which also contributes to the diversification of septic tanks. It has become.

Generally, septic tanks are installed by contractors. The installed septic tanks are obliged to be maintained and inspected and cleaned several times each year depending on the human tank, and the practice is generally outsourced to businesses such as local organizations and companies. Maintenance and inspection, cleaning and water quality inspection of septic tanks are collectively called maintenance, and are conventionally performed as follows. When a private house or local facility is constructed and a septic tank is installed, the business operator entrusted with the maintenance of the septic tank manages the matters to be managed based on the processing capacity, processing content, scale, and composition of the septic tank. List up and create an administrative checklist. In that case, identify the equipment and devices used in the septic tank one by one and list the items to be managed for each. The checklist for managing each septic tank created in this way is stored by the septic tank manager and the business operator entrusted with the management of the septic tank, and is taken out and used when managing the septic tank.

The maintenance and inspection of a typical conventional septic tank is performed as follows. The business operator entrusted with the maintenance and inspection of the septic tank first extracts a management checklist of a plurality of septic tanks to be maintained and inspected in one day, and the worker goes around with it. The order of patrol of septic tanks is decided in advance, and patrols are performed in that order. When you arrive at the septic tank installation location, select the management checklist that corresponds to the septic tank, and carry out maintenance and inspection work for each displayed item. Then, enter the fact that it was carried out in the relevant part of the management checklist. Repeat this for all items. If you receive a fee from the requester, also indicate that you have collected the fee on the management checklist. When the maintenance and inspection of the septic tank is completed, look at the list to find the next septic tank that has not been maintained and inspected, and move to that location. Then, the same maintenance and inspection work as the previous septic tank is repeated. After completing the maintenance and inspection of all septic tanks, bring back the management checklist and organize it, and make the necessary tabulations for the rest. The same procedure is used for cleaning by a business operator entrusted with cleaning the septic tank and water quality inspection of the septic tank by an inspection organization.

As described above, the operation of maintenance of septic tanks involves a plurality of businesses such as manufacturers, contractors, maintenance and inspection companies, cleaning companies, and inspection organizations. Therefore, in the conventional septic tank maintenance system, maintenance is rarely performed by a single operator, and the septic tank is a network of operators consisting of manufacturers, contractors, maintenance and inspection companies, cleaning companies, inspection organizations, etc. It is common for maintenance systems to be operated. However, since the septic tank management information in the maintenance management system is managed individually by each member, it is not possible to evaluate and confirm the operation status of the maintenance management system as a whole. For this reason, it is difficult to detect inconsistencies and inconsistencies in information between business network, and as a result, after individual problems occur, the relevance is discovered by the ex-post investigation. In fact, the frequency of inspections of general household septic tanks, which are installed most frequently in Japan, is at least once every four months (as of 2015) by law, and it is also possible to obtain management information between septic tank maintenance networks. Since there are individual time differences, the provision of real-time maintenance services is hindered due to delays in treatment measures and the like.

According to the conventional septic tank management system as disclosed in Patent Documents 1 to 7 described above, individual business operators can manage septic tanks reliably and efficiently, but information inconsistencies and contradictions among a plurality of business operators can be caused.

First, the operation of the device 1 for detecting an abnormality in the maintenance status of the septic tank by using the septic tank maintenance status abnormality detection device 1 (hereinafter, also simply referred to as “device 1”) according to the embodiment of the present invention. Explain how to use it. The configuration of the device 1 that realizes the operation of the device 1 will be described later.

The outline of the operation of the device 1 will be described. See FIG. The device 1 performs a primary evaluation, which is a behavioral evaluation of maintenance of the septic tank, based on various input data. The purpose of the primary evaluation is to check the management behavior of the business operator by evaluating the consistency between the actual behavior of maintenance and inspection and cleaning of septic tanks based on laws and regulations and the results of third-party evaluation of the quality of discharged water. Is. Further, the apparatus 1 performs the secondary evaluation using the result of the primary evaluation. The purpose of the secondary evaluation is to automatically extract and identify the problem by evaluating the appropriateness of the management content that is the result of the management action, and to identify the correction request or the cause investigation. The more specific operation of the device 1 is as follows.

The device 1 stores a water quality standard that is a water quality standard that should be satisfied by the inside of the septic tank and the treated water discharged from the septic tank. An example of the water quality standard is shown in FIG.

The user of the device 1 registers the information of the business operator who maintains and manages the septic tank in the device 1. An example of the item of business information is shown in FIG.

When a septic tank is newly installed, the user of the device 1 inputs the basic equipment information including the user of the septic tank, the installation location, the configuration of the equipment and the equipment, etc. into the device 1 based on the application from the installer. .. FIG. 6 shows an example of items of basic equipment information. The basic equipment information input to the device 1 is stored in the device 1.

Furthermore, the user of the device 1 prepares the equipment standard of the septic tank to be installed so as to comply with the laws and guidelines regarding the septic tank and the instruction manual prepared by the septic tank manufacturer based on the basic equipment information, and sets it. Input to device 1. At this time, for various equipment and devices used in the septic tank, the items of the equipment standard corresponding to each are registered in advance in the device 1, and the user of the device 1 uses the septic tank to be installed among those items. By selecting the equipment and equipment used in the above, it is possible to create the equipment standard of the septic tank to be installed. In addition, the equipment standards include inspection items for the quality of the treated water discharged from the septic tank. An example of equipment standard items is shown in FIG. The equipment standard input to the device 1 is stored in the device 1.

The septic tanks that have been installed will be regularly maintained and managed in accordance with the law. Typically, maintenance and inspection are carried out by a maintenance and inspection company, and cleaning is carried out by a cleaning company on behalf of the septic tank manager. When performing maintenance and inspection, the maintenance and inspection company carries, for example, a terminal connected to the device 1 wirelessly via a network in place of (or in combination with the management checklist) the conventional management checklist. To do. Based on the information managed by the device 1, the terminal displays a list of septic tanks in which the maintenance and inspection company carrying the terminal is in charge of maintenance and inspection. The maintenance contractor selects from the list one septic tank for which maintenance is to be performed. Then, the equipment standard of the septic tank stored in the device 1 is displayed on the terminal, and the actual state of each item of the equipment standard can be input. The business operator inputs the actual condition of each item into the terminal on the spot based on the result of maintenance and inspection. The actual condition of each input item is transmitted from the terminal to the device 1 as equipment actual condition data. When the cleaning company cleans the septic tank, it is the same as when the maintenance and inspection company performs maintenance and inspection.

When the device 1 receives the equipment actual condition data, it stores it. Further, the device 1 generates equipment evaluation information by comparing the equipment actual condition data with the equipment standard. The equipment evaluation information is either equipment normal information indicating that all items of the equipment actual condition data conform to the equipment standard, or equipment abnormality information indicating that any item of the equipment actual condition data does not conform to the equipment standard. Is. As an example of a specific evaluation method, for each item of the equipment standard, if there is a value of the corresponding item of the equipment actual condition data (that is, if there is no input omission), all of the equipment actual condition data regardless of the content. It can be evaluated that the item meets the equipment standard. The device 1 stores the generated equipment evaluation information.

In addition, the septic tanks that have been installed are regularly inspected by the inspection agency for legal water quality. When performing a water quality inspection, the inspection agency replaces (or together with the water quality inspection checklist) the conventional water quality inspection checklist, for example, with a terminal connected to the device 1 wirelessly via a network. Carry it. The inspection organization selects one septic tank for which the water quality is to be inspected from the list displayed on the terminal 1. Then, a list of water quality standard items is displayed on the terminal, and the inspection results of each item can be input. The inspection organization inputs the result of each inspection item to the terminal on the spot based on the result of the water quality inspection. The input results of each inspection item are transmitted from the terminal to the device 1 as water quality inspection result data.

When the device 1 receives the water quality test result data, it stores it. Further, the apparatus 1 generates water quality evaluation information by comparing the water quality test result data with the water quality standard. The water quality evaluation information is either normal water quality information indicating that all items of the water quality test result data conform to the water quality standard, or water quality abnormality information indicating that any item of the water quality test result data does not conform to the water quality standard. It is either. The device 1 stores the generated water quality evaluation information.

As shown in FIG. 3, when the equipment evaluation information and the water quality evaluation information are stored for one septic tank (referred to as “target septic tank”), the apparatus 1 performs the primary evaluation of the target septic tank according to these evaluation information. .. The primary judgment that is the result of the primary evaluation is one of normal judgment, equipment abnormality judgment, water quality abnormality judgment, and audit judgment. Specifically, the device 1 determines the primary judgment as follows based on the equipment evaluation information and the water quality evaluation information.

When the equipment evaluation information is the equipment normal information and the water quality evaluation information is the water quality normal information, the primary judgment is a normal judgment. When the device 1 outputs a normal judgment as the primary judgment, the user of the device 1 can understand that there is no problem in the maintenance of the target septic tank and the state of the target septic tank is also good.

When the equipment evaluation information is equipment abnormality information and the water quality evaluation information is water quality normal information, the primary judgment is the equipment abnormality judgment. When the device 1 outputs the equipment abnormality judgment as the primary judgment, the user of the device 1 understands that there may be a problem in the maintenance of the target septic tank, but the condition of the target septic tank is good. be able to.

When the equipment evaluation information is the equipment normal information and the water quality evaluation information is the water quality abnormality information, the primary judgment is the water quality abnormality judgment. When the device 1 outputs the water quality abnormality determination as the primary determination, the user of the device 1 can understand that the condition of the target septic tank is not good.

If the equipment evaluation information is equipment abnormality information and the water quality evaluation information is water quality abnormality information, the primary judgment shall be an audit judgment. When the device 1 outputs an audit judgment as the primary judgment, the user of the device 1 may not be in a good condition of the target septic tank, and the cause may be that the maintenance of the target septic tank is improperly performed. It can be understood that there is.

The device 1 can store the primary determination and output or transmit it to the outside as needed. In the septic tank maintenance status abnormality detection device according to another embodiment of the present invention, the primary determination may be the final output and the secondary evaluation described below may not be performed.

Next, the device 1 performs a secondary evaluation of the target septic tank. Secondary evaluation includes progress confirmation evaluation, management abnormality detection evaluation, follow-up / cause investigation evaluation, and guidance-required evaluation. The device 1 selects and executes the first evaluation from these secondary evaluations according to the primary determination, determines the secondary determination as a result of the secondary evaluation, and outputs the result. The relationship between the primary judgment and the secondary evaluation to be performed first, and the content of the secondary evaluation are as shown in FIG. 3, and specifically, are as follows.

When the primary determination is a normal determination, the device 1 performs a progress confirmation evaluation as the first secondary evaluation. The result of the progress confirmation evaluation is either a judgment of no abnormality or a judgment of past inspection water quality abnormality. The contents of the progress confirmation evaluation are as follows. That is, the device 1 has all or a part (for example, the latest two cases) of the past equipment actual condition data (referred to as "past equipment actual condition data") of the target septic tank that is stored in the septic tank. Compare the water quality data (referred to as "past inspection water quality data") inspected during maintenance or cleaning with the water quality standard. The result of the progress confirmation evaluation is judged as no abnormality if all the past inspection water quality data compared with the water quality standard conforms to the water quality standard, and if any of the past inspection water quality data does not conform to the water quality standard, the past inspection Judgment of water quality abnormality. If the result of the progress confirmation evaluation is a judgment without abnormality, the judgment without abnormality is used as a secondary judgment as it is. The user of the device 1 can understand that there is no problem in the target septic tank when the device 1 outputs a no abnormality determination as the secondary determination. On the other hand, when the result of the progress confirmation evaluation is the past inspection water quality abnormality determination, the device 1 subsequently performs the management abnormality detection evaluation to determine the secondary determination. In the septic tank maintenance status abnormality detection device according to another embodiment of the present invention, when the result of the progress confirmation evaluation is the past inspection water quality abnormality determination, the past inspection water quality abnormality determination is performed without performing the management abnormality detection evaluation. May be used as the secondary determination.

When the primary determination is the equipment abnormality determination, the device 1 performs the first management abnormality detection evaluation as the first secondary evaluation. Further, even when the result of the above-mentioned progress confirmation evaluation is the past inspection water quality abnormality determination, the device 1 performs the first management abnormality detection evaluation. The contents of the first management abnormality detection evaluation are as follows. That is, the device 1 compares each of all or a part of the stored past equipment actual data (for example, the latest three) with the stored equipment inspection standard. The equipment inspection standard is a standard for the actual equipment data set to detect the management problem of the septic tank. An example of the equipment inspection standard is shown in FIG. The result of the first management abnormality detection evaluation is follow-up observation / cause investigation judgment when all past equipment actual condition data compared with the equipment inspection standard conforms to the equipment inspection standard, and one of the past equipment actual condition data. If does not meet the equipment inspection standards, it will be judged as a management status confirmation. In any case, the result of the first management abnormality detection evaluation is used as the secondary determination. When the device 1 outputs a follow-up observation / cause investigation judgment as a secondary judgment, the user of the device 1 can understand that there is a problem in the target septic tank but the cause is other than maintenance inspection or cleaning. Yes, more specifically, improper installation or incorrect water quality inspection will be suspected. Therefore, the user of the device 1 can investigate the installation state of the target septic tank and the record of the water quality inspection to investigate the cause, or can observe the progress as it is. On the other hand, when the device 1 outputs a management status confirmation judgment as a secondary judgment, it can be understood that the target septic tank has a problem due to maintenance inspection or cleaning, and the problem is pointed out to the operator. Improvements can be requested.

When the primary determination is a water quality abnormality determination, the apparatus 1 performs follow-up observation and cause investigation evaluation as the first secondary evaluation. The contents of the follow-up / cause investigation evaluation are as follows. That is, the device 1 is the equipment of the target septic tank from all or a part (for example, for the last three years) of the past equipment actual condition data (referred to as "multiple equipment actual condition data") of the plurality of septic tanks stored. Extract the data created during maintenance and inspection or cleaning by the same operator as the actual data, and compare each with the equipment inspection standard. The result of the follow-up observation / cause investigation evaluation is the follow-up observation / cause investigation judgment when all the past equipment actual condition data compared with the equipment inspection standard conforms to the equipment inspection standard, and one of the past equipment actual condition data is used. If it does not meet the equipment inspection standards, it will be judged as needing improvement. If the result of the follow-up observation / cause investigation evaluation is the follow-up observation / cause investigation judgment, the follow-up observation / cause investigation judgment is regarded as the secondary judgment as it is. As described above, when the device 1 outputs a follow-up observation / cause investigation judgment as a secondary judgment, the user of the device 1 states that there is a problem with the target septic tank, but the cause is other than maintenance inspection or cleaning. I can understand. On the other hand, when the result of the follow-up observation / cause investigation evaluation is an improvement determination, the apparatus 1 subsequently performs a guidance evaluation to determine a secondary determination. In the septic tank maintenance status abnormality detection device according to another embodiment of the present invention, when the result of the follow-up observation / cause investigation evaluation is an improvement determination, the improvement determination is made without performing the guidance evaluation. It may be the next judgment.

When the primary judgment is an audit judgment, the device 1 performs a guidance evaluation as the first secondary evaluation. Further, even when the result of the above-mentioned follow-up observation / cause investigation evaluation is a judgment requiring improvement, the apparatus 1 performs a guidance evaluation. The contents of the evaluation required for guidance are as follows. That is, the device 1 is created at the time of maintenance inspection or cleaning by the same operator as the equipment actual condition data of the target septic tank from all or part of the stored multiple equipment actual condition data (for example, for the last 3 years). Extract what has been done and evaluate them based on the auditing criteria that you remember. The audit standard is a standard for equipment actual condition data set to detect improper maintenance and inspection of septic tanks or cleaning. For example, the number of septic tanks managed and maintained by a business operator per day is In monitoring for fraudulent maintenance or cleaning, such as whether the number of septic tanks that can be maintained and inspected per day is exceeded, which is calculated from the time required for maintenance and inspection of one septic tank and the working time per day. Judgment items that have been found to be effective empirically can be included. FIG. 9 shows a specific example of the check contents and check method of the auditing standard. In this example, as a result of the check, when the number of applicable items reaches a predetermined ratio, it is determined that the multiple equipment actual condition data does not conform to the equipment inspection standard. The result of the evaluation requiring guidance shall be an improvement request judgment if the actual data of multiple facilities conforms to the equipment inspection standards, and a judgment requiring guidance if the actual data of multiple facilities does not meet the equipment inspection standards. If the result of the guidance-requiring evaluation is an improvement request determination, the device 1 subsequently performs a second management abnormality detection evaluation to determine a secondary determination. The content of the second management abnormality detection evaluation can be the same as the content of the first management abnormality detection evaluation described above. In the septic tank maintenance management status abnormality detection device according to another embodiment of the present invention, when the result of the guidance-requiring evaluation is an improvement request determination, the improvement request determination is made without performing the second management abnormality detection evaluation. It may be a secondary judgment. On the other hand, in the device 1, when the result of the guidance-requiring evaluation is the guidance-requiring judgment, the guidance-requiring judgment is directly used as the secondary judgment. When the device 1 outputs a guidance-requiring judgment as a secondary judgment, the user of the device 1 has a serious nonconformity in the maintenance inspection or cleaning of the target septic tank, and makes an inquiry or guidance to the business operator. I understand that it should be.

Based on the above, the device 1 determines the secondary determination which is the result of the secondary evaluation of the target septic tank. The device 1 can store the secondary determination and output it to the outside.

The device 1 can notify the user of the device 1 of the secondary determination by e-mail or the like, if necessary. The device 1 may be set to notify all secondary determinations, but according to a given condition, for example, notifying only when the secondary determination is a management status confirmation determination or a guidance requirement determination. It can also be set to notify only some secondary judgments. By receiving the notification of the secondary judgment, the user of the device 1 quickly recognizes the problem related to the management of the septic tank, and if necessary, requests improvement, inquires, and gives guidance to the business operator who maintained the septic tank. It becomes possible to take measures such as.

The device 1 can aggregate and output the secondary determination of each septic tank stored in the device 1 as needed. For example, the device 1 can aggregate the secondary determination of the septic tank for which the business operator is in charge of maintenance and management for each business operator that maintains and manages the septic tank, and output a list. The list can be, for example, a matrix-type table in which the row is the business operator and the column is the type of secondary determination. FIG. 10 shows an example of the output format of the list of the aggregated results of the secondary determination. In this example, "G" in the column name means no abnormality judgment, "O" means management status confirmation judgment, "P" means follow-up / cause investigation judgment, and "M" means guidance required judgment. In addition, the aggregated result of the primary judgment can be output in the same format, and in that case, the normal judgment, the equipment abnormality judgment, the water quality abnormality judgment, and the audit judgment may be displayed in a column. Further, FIG. 11 shows an example of an output format in which the management status such as the number of secondary judgments is displayed for each business operator.
