  FIG. 1 is a block diagram illustrating a configuration of an entire water treatment management facility including the water treatment facility management system 100 according to the first embodiment of the present invention.

  This water treatment management facility is a water treatment process in which a water treatment facility management system 100 including a data input means 1, a display means 2, a database unit 10, and an information processing device 20 generates purified water from raw water via a network 210. Is connected to the monitoring control server 201 of the water supply facility 200 equipped with

  Here, the water treatment facility management system 100 is a water treatment process executed by the water treatment process execution unit 203 from the raw water in the water supply facility 200 through the water treatment process execution unit 203 and the water distribution facility 204 until purified water is obtained. Receiving water treatment data for a plurality of processes 1 to N and various management data required for the data (data contents corresponding to management operation instructions) in accordance with a monitoring cycle determined for each data from the monitoring control server 201 Then, it accumulates and stores in various databases of the database unit 10. In this water treatment facility management system 100, the HACCP method is applied, and it has a function of setting a management reference value (CL) with respect to a monitoring value of a critical control point (CCP), and an operator (manager) at the time of crisis management. It has a function for presenting corresponding examples to support operation judgment and technology inheritance.

  For each part of the water treatment facility management system 100, the data input means 1 attached to the information processing apparatus 20 is used for inputting necessary information to the database unit 10 in this system, and is a keyboard provided in a normal computer. It is also possible to configure using, for example. Similarly, the display means 2 attached to the information processing apparatus 20 is a series of water treatment data related to past management operation instructions executed in a plurality of water treatment processes accumulated and stored in various databases of the database unit 10. In addition, the data content of various management data is to display the fluctuation of the water quality status, countermeasures, operation methods, and alarm output in time series on the display screen, and be composed of a normal display etc. Is possible. Thereby, the management / operator of the water supply facility which is an operator can confirm the management operation content on the display screen.

  The database unit 10 includes a water quality database 11, a management reference value database 12, an operation history process database 13, a learning history information database 14, and a display speed management database 15. The information processing apparatus 20 includes a data collection processing unit 21, an alarm output processing unit 22, a reproduction display processing unit 23, a display speed change processing unit 24, and a selection operation method / operation history information comparison processing unit 25. Is done.

  The configuration of each unit in the database unit 10 will be described. The water quality database 11 accumulates and stores water quality data including the results of water quality inspections and measurement results of the water supply facilities during management and operation of waterworks facilities. This is for collecting and updating necessary data for reviewing the data.

  The management reference value database 12 is for storing management reference values set as management indicators for water quality data when managing and operating waterworks facilities.

  The operation history process database 13 accumulates and stores operation histories performed on the raw water in the water supply facility 200 over time, and stores the data contents in each step 1 to N of the water treatment process in which the operation was performed. When storing and storing, and diagnosing that the data content related to the water treatment process of the water supply facility 200 is within the preset management reference value, and detecting data indicating out of the management reference value range This is for accumulating and storing the date and time of alarm output and the content of the alarm.

  The learning history information database 14 reproduces and displays the water quality on the display unit 2 based on the past accumulated data contents corresponding to the management operation instructions executed in each step of the water treatment process received via the monitoring control server 201. When iterative confirmation (learning) is performed as a time-series flow of status change, response means, operation method, and alarm output, the results are accumulated and stored as learning information history data. Further, an education support plan for a case where the operator becomes a newly appointed person or takes over is similarly accumulated and stored as learning information history data.

  When the display speed management database 15 reproduces and displays on the display means 2 based on the past accumulated data content corresponding to the management operation instruction performed in each step of the water treatment process received via the monitoring control server 201, This is for storing a management table before change corresponding to data before changing the display speed as shown in FIG. Further, during the reproduction display, when the water quality data is close to the management reference value, it corresponds to the data after the display speed change as shown in FIG. 3 which is referred to when the reproduction display speed is temporarily changed. The post-change management table is also stored.

  Furthermore, if the structure of the database part 10 is illustrated in detail, the water quality database 11 of the database name includes a water quality analysis item, a water quality analysis result, a measurement place, and a measurement date and time as items. The management reference value database 12 includes, as items, a water quality data management index, a water quality data management reference value, and a water quality reference value for determining a change in the reproduction flow display speed. The operation history process database 13 includes operation history, process data, alarm occurrence date and time, and alarm contents as items. The learning information history database 14 includes a learning history, a learning example, and an education support plan as items. The display speed management database 15 includes, as items, a display speed for reproduction display and a display speed when the water quality data is close to the management reference value.

  The configuration of each unit in the information processing apparatus 20 will be described. The data collection processing unit 21 collects water quality data and operation history process data (including alarm history) including the water quality analysis result and measurement data of the water supply facility 200 transmitted from the monitoring control server 201 via the network 210. , Each has a function of accumulating and storing in the water quality database 11 and the operation history process database 12.

  The alarm output processing unit 22 determines whether or not the instantaneous value and the integrated value are valid in the operation history process data of the water supply facility 200 received from the management control server 201. The operation history process data determined to be valid has a function of comparing a management reference value set in advance and outputting an alarm if it is outside the range of the management reference value. The management reference values applied here include upper and lower limit values, correlation analysis values, statistical analysis values and the like for the operation history process data, and these numerical values are input by the data input means 1 in advance. Further, the contents of the data such as the alarm name and the time of occurrence of the alarm output here are also accumulated and stored in the operation history process database 12.

  The reproduction display processing unit 23 is a management result implemented in each step of the water treatment process accumulated and stored in the operation history process database 13 as a result of the fluctuation of the water quality situation with time change of the water quality data stored in the water quality database 11. Based on past accumulated data contents corresponding to the operation instruction (received via the monitoring control server 201), the display means 2 as a flow visualizing the history of the water quality status, the response means, the operation method, and the alarm output history It has a function to reproduce and display in time series.

  The display speed change processing unit 24 has a function capable of changing the speed of the data content reproduced and displayed on the display screen of the display means 2 by the reproduction display processing unit 23. The normal display speed is the display speed management database 15. 2 is set in advance by referring to the management table before change shown in FIG. 2, and is determined by specifying the data in the management table before change in response to the operation instruction of the data input means 1. With this function, it is possible to shorten the time for displaying and reproducing the flow, and the operator can check the data contents of the flow within a short time, so that it is possible to improve the work efficiency.

  Here, if the flow reproduction display speed is high, the operator cannot clearly (detailed) confirm local fluctuations in the past, signs of change, etc., regarding details of past response cases and fluctuations in water quality data. It is assumed that the reproducible display progresses or an oversight occurs. Therefore, in order to prevent such problems, the reproduction display speed should be set when an operation input for management by the operator is performed, when an alarm is output, or when water quality data is close to the management reference value. It is desirable to provide a function to change (slow) temporarily to assist the operator in confirming the details of the contents displayed in the flow. Specifically, the change of the display speed in such a case is performed by the post-change management table (FIG. 3) stored in the display speed management database 15 preset by the operator according to the operation instruction of the data input means 1. In comparison with the pre-change management table shown in FIG.

  For example, when the water quality data becomes a value in the vicinity of the management standard value, the judgment standard (timing) when starting the change of the reproduction display speed is Xi as the water quality data and Di as the management standard. Value, αi is a criterion, i is an item number for each water quality data. In this case, it is determined whether or not the water quality data and the management reference value satisfy the relational expression (| Xi−Di | / Di) ≦ αi. In addition, since the management standard value of water quality data actually determined in the water treatment plant is different, the management standard value and the judgment standard value are defined for each water quality item, and the management standard value is stored in the management standard value database 12. It shall be stored and stored.

  The selection operation method / operation history information comparison processing unit 25 temporarily stops the display screen reproduced and displayed based on the operation history process data at the timing when the alarm output or the management operation instruction is performed. Then, data of choices on how to perform the next operation for the operator is displayed in a pop-up on the display screen, and the data input means 1 displays the data so that the operator can selectively input operation instructions. Adopt a method. At this time, items to be displayed as option data are quantitative data such as process process names, processes, and injection amounts of chemicals. In addition, it is desirable to adopt an interface that enhances the learning motivation of the operator, for example, by adopting a method of selecting by a three-way selection method.

  Further, the selection operation method according to the operation instruction input which is the data content selected by the operator is compared with the operation history information which is the past corresponding case, and the determination result based on the operation instruction input and the past Only when the above operation matches, the display screen that has been paused is canceled and restarted, and the flow display can be confirmed subsequently.

  That is, the function of the selection operation method / operation history information comparison processing unit 25 works, so that it is possible to repeatedly check the water treatment process from raw water to purified water, and it is possible to perform judgment support and training simulation for the operator.

  In addition, the contents corresponding to the management operation instructions in a plurality of steps of the water treatment process, including data on whether or not the judgment according to the result of the input of the operation instructions on the option data by the operator matches the past operation Learning information (implementer's name, date and time of implementation, type of response case, etc.) when iterative confirmation of data is performed is collected as data by the data collection processing unit 21 and accumulated and stored in the learning information history database 14 By doing so, it is possible to visualize the technology acquisition and technology succession schedule necessary for management and operation, and it is possible to systematically promote and support the technology acquisition and technology inheritance.

  In short, the basic function of each part of the information processing apparatus 200 will be briefly described. The alarm output processing unit 22 outputs an alarm when the water quality data deviates from the range defined by the management reference value. The reproduction display processing unit 23 includes, as data contents about a series of water treatment data and various management data in accordance with the management operation instruction, the fluctuation of the water quality status related to the water quality data, the operation method related to the operation history process data, and the alarm output Is reproduced and displayed in time series on the display screen of the display means 2. When the data content corresponding to the management operation instruction is reproduced and displayed on the display screen, the display speed change processing unit 24 variably processes and displays the display speed when the water quality data becomes close to the management reference value.

  In addition, when the selected operation method / operation history information comparison processing unit 25 reproduces and displays the data contents corresponding to the management operation instruction on the display screen, the selection operation method / operation history information comparison processing unit 25 is based on the operation history process data on which the alarm output or the management operation instruction is executed. The display screen is paused, and the option data indicating how the next operation instruction should be given to the operator is displayed on the display screen so that the operation instruction can be input, and the selection according to the operation instruction input As a result of comparing the operation method and the operation history information, only when the judgment based on the operation instruction input matches the past operation, the pause of the display screen is canceled and the reproduction display is resumed. The data collection processing unit 21 includes data indicating whether or not the judgment according to the result of the input of the operation instruction regarding the data of the option by the operator and whether or not the past operation matches, and the management operation instruction in each step of the water treatment process. The learning information when the repeated confirmation of the corresponding content data is performed is collected as a history.

  In the water treatment facility management system 100 according to the first embodiment described above, the water treatment process execution unit until the information processing apparatus 200 obtains purified water from the raw water in the water supply facility 200 through the water treatment process execution unit 203 and the water supply and distribution facility 204. The water treatment data relating to each step 1 to N of the water treatment process executed in 203, and various management data required for the water treatment process are taken from the monitoring control server 201, stored in various databases of the database unit 10, and stored therein. As a data content of a series of water treatment data and various management data according to the management operation instruction in FIG. 10, information on the fluctuation of the water quality status related to the water quality data, the operation method related to the operation history process data, and the alarm output information are displayed. 2 has a function for presenting a corresponding example that is reproduced and displayed in time series on the display screen.

  As a result, it is possible for the operator to repeatedly check the contents of past management operations by performing a simulation. Therefore, as in the case of the water treatment facility management method described above, the technology inheritance between operators (persons in charge) can be performed. Educational tools that can be supported can be provided, and it is possible to effectively support operation judgment and technology transfer for the operator even during crisis management. In addition, since information can be shared among operators, it is possible to systematically and effectively promote and support technical acquisition and technical succession regarding management operations for cultivating the management ability of water quality managers.

  As is well known, the information processing apparatus 20 in the water treatment facility management system 100 described above includes a storage device such as a simplified CPU, main memory, HDD, and the like. Instead of the corresponding example presentation function that can reproduce the rise and fall of water quality data that is constructed in cooperation with each other, and supports the operation judgment and technical succession at the time of management operation instruction to the operator, it was first described In addition to a mode in which the CPU executes a water treatment facility management program having information on each step of the water treatment facility management method, information on each step from the water treatment facility management recording medium in which information on each step is recorded Can be read and executed.
