Description

  In the present invention, inspection and maintenance are performed by circulating through septic tanks of facilities and the like dispersed in private houses and regions, or inspection and cleaning of these septic tanks are performed, and reports and the like are prepared on the spot. The present invention relates to a portable input / output terminal for managing a septic tank for management and a control program used for the terminal.

  Water and sewage systems have been developed since ancient times and are indispensable to human society. Sewage is of particular importance today to prevent environmental pollution. Large-scale sewage systems have been developed in large cities as sewage treatment systems from receiving sewage to processing and draining, but large-scale sewage systems in areas where buildings and facilities are dispersed in terms of cost. It is difficult to lay the wastewater, and distributed septic tank systems are often used.

  Septic tank systems used in private homes and regional facilities have various configurations depending on the processing capacity and processing content.Also, even with similar scales, the equipment used differs, so most septic tanks are configured. It is no exaggeration to say that they are different. On the other hand, septic tanks are required to be inspected several times a year, and maintenance such as cleaning and adjustment is required according to the situation, and the practice is outsourced to local organizations and companies. And, in many cases, a plurality of companies share and manage. Against this background, conventional septic tanks are managed as follows.

  When a private house or local facility is constructed and a septic tank is installed, items to be managed based on the processing capacity, processing content, scale, and configuration of the septic tank are listed, and a septic tank checklist for management is created. Is done. In that case, the equipment and equipment to be used are identified one by one and the items to be managed for each are listed. The septic tank checklist of each septic tank created in this way is stored in the management building of the company entrusted with the management, and is taken out and used for management.

  When managing septic tanks, a consigned company extracts a septic tank checklist for a plurality of septic tanks that are managed in one day, and an operator takes it on a patrol car and patrols. When patrol, first determine the order of patrol of the septic tank, and patrol in that order. When the user arrives at the place where the septic tank is installed, a sheet corresponding to the septic tank is selected, and a management operation is performed for each item displayed. Then, the fact that the operation has been performed is entered in the relevant portion of the sheet, and the same is repeated until all the items are completed. If a fee is received from the requester, the fact that the fee has been stored is also indicated on the septic tank check sheet. When the septic tanks are managed, the user looks at the list and finds the next order of the septic tanks that have not been managed, searches for the place, and moves by car. And the same operation as the previous septic tank is repeated and managed. When all the septic tanks on the list have been managed, the septic tank check sheet is returned and the totals required for the subsequent calculations are calculated.

  The inventors of the present invention described in Patent Document 1 for the purpose of making it possible to efficiently and reliably prepare the septic tank check sheet and to manage the septic tank safely, reliably, and efficiently. A septic tank management system was developed. According to this septic tank management system, the work items are displayed in order on the portable input / output terminal of the worker, so that the worker can perform the work of the item as displayed.

  FIG. 10 shows a transition example of a screen displayed on the portable input / output terminal. As shown in FIG. 10, for example, when performing inspection and maintenance of a raw water pump, work items for inspection and maintenance are displayed in order on the screen of the portable input / output terminal according to the septic tank check list. The worker performs inspection and maintenance of the raw water pump based on the content displayed on the screen of the portable input / output terminal, and inputs the result to the portable input / output terminal.

JP-A-2002-230145

  Incidentally, the management of the septic tank is generally performed as a set of operations including inspection and maintenance. That is, as shown in FIG. 10, the main body of the raw water pump is checked for any abnormality, and if there is an abnormality in the main body, the maintenance is continuously performed. In addition, the fixing condition of the pump equipment is checked, and if there is a defect, the maintenance is continuously performed. Thus, in the management of the septic tank, if any abnormality is found by the inspection, the maintenance is performed following the inspection, but if no abnormality is discovered, the maintenance need not be performed.

  However, in the above-described conventional septic tank management system, even if no abnormality is found by the inspection, the maintenance item corresponding to the inspection item is continuously displayed on the portable input / output terminal. Therefore, when no abnormality is found by the inspection, the operator needs to skip the maintenance item displayed following the inspection item without inputting anything. Therefore, if no abnormality is found by inspection, no maintenance is required, but it is necessary to skip the screen every time for maintenance items displayed on the portable input / output terminal.

  As described above, in the conventional septic tank management system, the operator determines whether the maintenance item is required at that time from the maintenance items displayed on the portable input / output terminal following the inspection item. It is necessary to make a judgment and, based on the judgment, skip the screen for unnecessary maintenance items. Therefore, if the operator makes a mistake, there is a possibility that necessary maintenance may be skipped or unnecessary maintenance may be performed. If necessary maintenance is skipped, it is necessary to start over again later, so that the screen of the portable input / output terminal must be returned in order, thereby lowering work efficiency.

  Therefore, the present invention provides a portable input / output terminal for septic tank management capable of efficiently performing an operation by eliminating an artificial necessity determination regarding maintenance performed based on an inspection result, and a control program used therefor. The purpose is to provide.

  A portable input / output terminal for septic tank management according to the present invention is a portable septic tank management portable terminal for sequentially displaying each check item and each maintenance item included in a septic tank check sheet used for management work including inspection and maintenance of a septic tank. Input / output terminal having means for switching the display of each maintenance item between display and non-display in accordance with the input content of each inspection item corresponding to each maintenance item.

  According to the portable input / output terminal for septic tank management of the present invention, among the maintenance items included in the septic tank check sheet displayed in order, depending on the inspection result of each inspection item, maintenance corresponding to the inspection item is required. Unnecessary or unnecessary items are automatically switched on or off.

  The portable input / output terminal for septic tank management according to the present invention includes a control for functioning as a means for switching display of each maintenance item to display or non-display in accordance with the input content of each inspection item corresponding to each maintenance item. This can be realized by executing a program.

  The portable input / output terminal for septic tank management according to the present invention is preferably further provided with means for switching the display of inspection items between display and non-display in accordance with the execution cycle of each inspection item. As a result, among the inspection items, items that require or do not require the current inspection depending on the execution cycle are automatically switched to be displayed or hidden.

  This portable input / output terminal for septic tank management can be realized by a control program for functioning as a means for switching the display of inspection items between display and non-display in accordance with the execution cycle of each inspection item.

  According to the present invention, the following effects can be obtained.

  Next, a septic tank management method by the septic tank management system according to the present embodiment will be described with reference to the flowchart of FIG.

(S1) When starting the management of the septic tank, first, the management computer 1 and the mobile computer 2 in the management building 10 are connected by wire or wirelessly, and the original management file 16 stored in the storage device 15 of the management computer 1 is read. From inside, the check sheets 261 of the septic tanks patrol on that day or all the septic tanks patrol for several days are downloaded and stored in the storage device 25 as the child management file 26. Then, the mobile computer 2 is mounted on the traveling vehicle 20.
(S2) When the mobile computer 2 is started, the location information including the location of the septic tank 4 or the map information is displayed on the display device 23 based on the information included in the child management file 26. Head to septic tank 4.

(S3) When arriving at the septic tank 4 to be inspected, the mobile computer 2 and the portable input / output terminal 3 are connected by wire or wirelessly, and only the check sheet 361 of the septic tank is downloaded from the mobile computer 2 and the portable input / output is performed. It is stored in the storage device 35 of the terminal 3.
(S4) The worker gets off the car with the portable input / output terminal 3 and moves to the septic tank.
(S5) When the portable input / output terminal 3 is activated, the first work item of the septic tank check sheet 361 is displayed, and if it is the second time or later, the work items in order are displayed.

  Here, the display device 33 of the portable input / output terminal 3 displays only inspection items that need to be inspected at that time in accordance with the execution cycle of the operation items. Do not show. This is due to the operation of the control program described above. For example, the condition of the execution cycle of each check item is set to a period such as once a year such as a check of insulation resistance or once a month such as a check of the state of formation of accumulated sludge.

  In the septic tank management system according to the present embodiment, as described below, all data of the work execution status is uploaded to the management computer 1 via the mobile computer 2 and is managed, so that the management computer 1 2, the data downloaded to the portable input / output terminal 3 includes the last inspection date, that is, the last inspection date of each work item. Therefore, the portable input / output terminal 3 displays, on the display device 33, only the items to be inspected at that time among the respective operation items based on the number of days elapsed from the final inspection date to the current operation date. .

  In addition, for each maintenance item among the work items, normally, following the display of the above-mentioned inspection items, the items corresponding to the respective inspection items are displayed after going through the following steps (S6) to (S9). You. However, in the septic tank management system according to the present embodiment, only necessary maintenance items are displayed according to the input contents of step (S7) described later of each inspection item corresponding to each maintenance item, that is, the inspection result, and unnecessary items are displayed. Is not displayed. This is due to the operation of the control program described above. FIG. 7A shows a transition example of a screen displayed on the display device 33.

(S6) The worker performs the work of the item as displayed on the display device 33 of the portable input / output terminal 3. The operator automatically switches the display or non-display of the inspection items having different execution cycles as described above and displays the inspection items on the display device 33 of the portable input / output terminal 3. In some cases, it is not necessary to judge for yourself what work is necessary or unnecessary. Also, regarding the maintenance item, the display or non-display of the maintenance item is automatically switched and displayed on the display device 33 of the portable input / output terminal 3 according to the inspection result of the previous inspection item. Depending on the inspection results, there is no need to judge for yourself what maintenance is necessary or unnecessary.

(S7) When the displayed work is performed, the fact that the work is performed is input from the input device 31 of the portable input / output terminal 3, and is entered in the relevant portion of the septic tank check sheet 361. Here, for example, when a check is input for "no abnormality" in the display of the inspection item shown on the left side of FIG. 7A, the inspection item corresponding to the inspection item in step (S5) is described above. The maintenance item is hidden, and only when the “abnormal” is checked, the maintenance item corresponding to the inspection item is displayed, and the content of the maintenance can be input.

  FIG. 7B shows an example in which a maintenance item corresponding to each inspection item is displayed when “abnormal” is checked. By the way, there are two types of maintenance: a case where a response can be made on the spot, a case where a response cannot be made, and a case where a situation is observed without a response on the spot. Therefore, when the response can be made on the spot, as shown in FIG. 7B, the content of the maintenance is input in the item of the maintenance. Here, the input maintenance contents and the like are recorded on the septic tank check sheet 361 and remain as past results, so that they can be seen at the next inspection.

  On the other hand, when it is not possible to respond immediately or when looking at the situation, as shown in FIG. 7 (c), enter what kind of situation is in the item of maintenance and check "Maintenance required". The contents of this check are recorded on the septic tank check sheet 361 and are reflected in the next and subsequent schedules, so that the person in charge determines the urgency and responds at a later date. If the response has been completed, it is processed as "maintained". Further, the contents of the maintenance response and the like at this time are recorded on the septic tank check sheet 361 as described above and remain as past results, so that they can be seen at the next inspection.

(S8) The portable input / output terminal 3 determines whether all items of the septic tank check sheet 361 have been completed.
(S9) If all the items have not been completed, the process proceeds to (S5) and the subsequent procedure is repeated.

(S10) If all the items have been completed, the worker brings the portable input / output terminal 3 back to the patrol car 20, and uploads the septic tank check sheet 361 updated with the input data to the mobile computer 2. This completes the inspection of one septic tank. At the end of the work on all items, if there is a payment from the septic tank management requester, that information is also input to the portable input / output terminal 3 and added to the septic tank check sheet.

(S11) Next, the mobile computer 2 determines whether or not the next inspection place remains.
(S12) If it remains, the mobile computer 2 moves to the next inspection place displaying the location information including the location or the map information by the patrol car 20, moves to (S3), and repeats the subsequent procedure.
(S13) If the next inspection place does not remain, the work to be performed for all the septic tanks managed on that day has been completed. Upload to.
(S14) Thus, all the data of the execution status of the work managed on that day is uploaded to the original management file 16 of the storage device 15, and the necessary calculations and the like for the subsequent processes and procedures are appropriately performed.

  In addition, the order of patrol of the inspection place when moving to the next inspection place at (S1) and (S12) is determined in advance so that the patrol can be performed efficiently, and the information is included in the child management file 26. I have. The most efficient route is determined in consideration of the geographical positional relationship, traffic conditions, road conditions, and the like.

  As described above, in the septic tank management system according to the present embodiment, the data of the septic tank for one day or the data of the septic tank for several days in which each worker is in charge of patrol is downloaded to the mobile computer 2. And downloads the data of the septic tank 4 from the mobile computer 2 to the portable input / output terminal 3 and manages the data according to the instructions. Therefore, the management by the worker is surely performed without omission.
