Description

  The present invention relates to a system for using information managed by a water utility, and in particular, to use information in a water supply facility that performs management based on the concept of HACCP (Hazard Analysis and Critical Control Point of evaluation). About the system.

  In recent years, the management of food safety has become important, and for example, information disclosure such as displaying the results of all-head inspection as a countermeasure for mad cow disease and the production area of food has been made. Water supply is one of the important lifelines, and it is the responsibility of the water utility to always maintain and manage the safety of water supply.

  There is a demand from customers not only for safety but also for delicious water, and advanced treatment using activated carbon or ozone is performed at water purification facilities in various places. However, at the same time as the water quality of the water source is deteriorating, a certain number of water quality accidents such as oil spills and ammonia nitrogen inflows occur every year.

  For this reason, it is expected that water quality and management information disclosure and accountability will be further required in the future from the viewpoint of safety, as well as food, and the taste that is directly recognized by consumers.

  On the other hand, in Japan, discussions have been held on the integration and widening of multiple water utilities due to the merger of municipalities and the flow of subsidies for water projects. With the widening of the water supply business, it is expected that personnel will be reduced for maintenance and outsourcing, but maintenance will be maintained while maintaining a sufficient level of management for accountability to water consumers. It is necessary to improve the efficiency of management work.

  Patent Document 1 proposes an information disclosure system for water consumers as a circulation type provision / utilization system of environmental information. It collects information on water supply as environmental information, manages water quality information and equipment information at water sources, water purification plants, pumping stations, etc., and discloses it to water customers regarding the safety and taste of water. Here, the water utility takes account of the water consumer, creates information, and transmits it to the water consumer again, thereby fulfilling accountability of the water utility.

  On the other hand, in Patent Document 2, as a management system for a piping network in city gas and water supply, the anticorrosion state and fluid pressure of each piping line are displayed on a map to make it easy to understand the management of the piping network by an administrator. Is disclosed. In this system, display of measurement results at each measurement point and trend of measurement results can be shown. As a result, it is possible to easily display to the administrator the corrosive state of the pipe that progresses in the medium and long term, and the range of pressure drop due to local pipe closure due to construction or the like.

Japanese Patent Laid-Open No. 2003-185100 (summary, other overall)

  In the said patent document 1, it is supposed that the water quality data in a pump station or a water distribution pipe is made into a management object, and can be increased / decreased suitably according to the kind of measurement object and the number of data measurement points. However, there are more than 200 items that are subject to water quality inspection in the water quality standard items and the like, and the water supply range from one pump station is wide, and the water supply population is thousands to tens of thousands. Furthermore, since the water supply is continuously taken, purified, and distributed, the quality of the raw water changes, the generation of disinfection by-products, the plumbing, etc. cause time fluctuations in the water quality. For this reason, in the above-mentioned conventional technology, it is necessary to measure personnel and personnel for manual analysis in order to present the details of water quality data to individual consumers while suppressing the characteristics of water supply such as items, supply ranges, and time fluctuations. There is a disadvantage that the cost including the cost becomes enormous.

  It also provides information by determining the level of “safe water” and “delicious water” from water quality data based on several water quality items. However, as described above, water quality measurement points and frequency are limited in terms of cost effectiveness. In addition, if there is a construction between the water quality measurement point and the water customer, there is a possibility that the water will be contaminated by harmful substances after that point due to the generation of disinfection by-products and the pathogenic bacteria Ligrouse. Therefore, the above-described conventional technique has a drawback that it is not sufficient in providing appropriate information for the expected harm to individual consumers.

  On the other hand, in Patent Document 2, management information such as the anticorrosion potential of the pipe and the measured value of the pressure is displayed in an easy-to-see manner for the administrator, but it cannot fulfill the accountability to the consumer.

  FIG. 1 is a functional block diagram of an information utilization system in a water supply facility according to an embodiment of the present invention. The water supply facility 1 purifies the taken raw water 11 at the water purification facility 12 and supplies it to the water consumer 14 through the water supply / distribution / water supply facility 13. The water purification facility 12 includes processes 12A, 12B, ... 12N. These water purification facilities 12, water supply, water distribution, and water supply facilities 13 are measured and monitored by a measuring device 15, a process data measuring device 16, and a water distribution data measuring device 17.

  An information utilization system in a water supply facility according to an embodiment of the present invention includes a measuring device / information management system 2 that manages the water supply facility 1. The measurement device / information management system 2 can be divided into a measurement data buffer unit 20, a database unit 30, and a calculation unit 40 in a hierarchical manner. On the other hand, the functions are roughly divided into the HACCP system 50, the data analysis system 60, the display means 70, and the data editing means 80.

  These functions will be described first from the HACCP system 50. The HACCP system 50 includes a measuring device 15, a process data measuring device 16, a water quality data buffer 21, a process data buffer 22, a water quality data storage unit 31, a process data storage unit 32, a diagnostic rule storage unit 33, and a diagnostic unit 42. ing.

  The measuring device 15 and the process data measuring device 16 are indirectly related to the hazardous substance concentration or the hazardous substance concentration in the process (for example, the B process 12B of the water purification facility 12) set in the important control point (CCP) of the target water system. Measurement and measurement of process data at a predetermined frequency. For example, when a pathogen is set as a hazardous substance, a chlorine mixing pond as CCP, a residual chlorine concentration measuring device that is a measurement related to the hazardous substance concentration as a measuring device 15, and a flow rate and chemical addition rate as a process data measuring device 16 are measured. It can be set as a device. These data are transmitted and recorded using a public telephone line, the Internet, an optical fiber communication network, etc. in addition to a dedicated line.

  The water quality data storage means 31 and the process data storage means 32 record the data obtained by the measuring device 15 and the process data measuring device 16 together with date / time information. The diagnostic rule storage means 33 records an appropriate range (upper limit value or lower limit value) of measurement values of the measuring device 15 and the process data measuring device 16 and a warning content when the measurement value deviates from this range. The value of the appropriate range shall be set to a value that satisfies these criteria by direct measurement for hazardous substance items for which tap water quality standards and guidelines exist, or a value that is necessary to satisfy the criteria for indirect measurement. For example, “abnormal” is set as the warning content. In setting the appropriate range, not only the upper and lower limit values but also stepwise numerical values can be set in order to determine how much value the appropriate range is. The warning content at this time can also be set as “n% of set value”, “large”, “small” or the like according to the stage.

  The diagnosis means 42 compares the value set in the diagnosis rule storage means 33 with the data recorded in the water quality data recording means 31 and the process data recording means 32 or the value obtained by the concentration analysis means 41 with the set value, and the measurement data Warning content is output when the value deviates from the set value.

  Next, the data analysis system 60 includes the water distribution data measuring device 17, the water distribution data buffer 23, the geographical information storage means 34, the water distribution data storage means 35, the concentration analysis means 41, and the display information selection means 43.

  The water distribution data measuring device 17 measures the amount of treated water and the flow rate, water pressure, water temperature, and water level in the water supply / distribution / water supply facility 13. These data are transmitted using a public telephone line, the Internet, an optical fiber communication network, etc. in addition to the dedicated line, and are recorded in the water distribution data storage means 35. Moreover, the demand pattern of water is also recorded here.

  The geographic information storage means 34 records geographic information about the intake of the raw water 11, the water purification facility 12, the water supply / distribution / water supply facility 13, and the water customer 14. In addition to the geographical information of the water distribution pipes in the water transmission / distribution / water supply facility 13, the pipe diameter, the pipe length, the material, and the connection relationship between the pipes are also recorded.

  The concentration analysis unit 41 estimates the flow time and hazardous substance concentration at an arbitrary point using the information in the geographic information storage unit 34, the water distribution data storage unit 35, the water quality data storage unit 31, and the process data storage unit 32. As a specific method, pipe network calculation is performed. First, the expected demand pattern, process data, and measured values of the flow rate are read, and the flow rate calculation is performed using a pipe network model. Next, the actual value and the estimated value of the flow rate are compared, and the demand pattern is adjusted as necessary. Then, after the flow rate calculation is completed, the concentration of the hazardous substance is estimated. In the concentration estimation, in addition to the change in the outlet water quality of the water purification facility 12, decomposition in the pipe network such as residual chlorine and generation in the pipe network such as disinfection by-products are considered. As a means for estimating the concentration, a flow time map for a plurality of water distribution patterns other than the pipe network calculation is prepared in advance, and the concentration of the hazardous substance at an arbitrary position using the data of the outlet water quality of the water purification facility 12 May be estimated.

  The display information selection means 43 sets and displays information to be displayed on the display means 70 using the water quality data, process data, geographic information, and the analysis result by the concentration analysis means. The display information selection means 43 selects one of the two types of presentation information as display information. As an information presentation function, one is a display function when a monitoring result deviates from a set value and a processing condition or water quality value in CCP deviates from a preset range. This is to predict the spread of hazardous substances (concentration prediction), and to show how the concentration of hazardous substances contained in treated water changes temporally and geographically in the pipe network. is there. The other is a processing history display function in the case where harm occurs to water customers or a possibility of harm occurs. This is one of the functions for clarifying the cause of the occurrence of harm or the possibility of occurrence, and shows the processing conditions at least in the CCP for the water supplied to the customer. .

  In the display information selection means 43, the data sources for which display is selected include water quality data in CCP, process data, and concentration analysis data obtained by the concentration analysis means 41. In addition to these, there are data obtained by other than CCP, for example, raw water quality, water quality at the faucet, process data at water intake facilities, water purification facilities, water distribution facilities, and the like. It is also effective to present these data as indicators that are easy for water consumers to understand. For example, the relative evaluation value R of the hazard may be calculated from the equation (1) by using water quality data related to the hazard similar to the hazard related to the item diagnosed as abnormal or a concentration analysis result.

Here, M ⁱ _n data measurement or analysis item i about harm substance n, S ⁱ _n the set value of the measurement or analysis item i about harm substance n, m is the number of harm material regarding similar hazards.

  FIG. 2 is an example of a specific processing flow by the display information selection unit 43 in the embodiment of the present invention. Here, it is assumed that the above-described evaluation data R and CCP monitoring data are displayed. The user of information selects the date and time, the location (or district), the target hazardous substance (or harm), and the type of display (concentration prediction or history display) regarding the water for which information is to be obtained in step 201. In step 202, the CCP of each hazardous substance is acquired from the diagnosis rule storage means 33 for the set hazard. When the concentration prediction is selected in step 201, the monitoring data in the CCP at the specified date and time is acquired from the water quality data storage means 31 and the process data storage means 32 in step 204. The acquired data is diagnosed by the diagnostic means 42 at step 205, and if the set value is exceeded, the distribution of each hazardous substance in the pipe network is obtained by the concentration analyzing means 41 at step 206. Next, the evaluation value R is calculated in step 207 using the value obtained in step 206. If R ≧ 1, the color corresponding to the value of R is displayed on each facility and pipe on the map.

  On the other hand, when the history display is selected in step 201, the flow time to the set place is calculated in step 211, and the date and time when the vehicle passes through a preset facility such as a water intake facility, a water purification facility, and a water reservoir is calculated in step 212. . Next, in step 213, monitoring data from the date of water intake to the date of arrival at the customer is acquired from the water quality data storage means 31 and the process data storage means 32. In step 214, the hazardous substance distribution is calculated within the time range obtained from the concentration analysis means 41, and in step 215, the R value is calculated. In step 216, the color corresponding to the R value of the date and time when the water whose information is desired passes through each facility / pipe is displayed on each facility / pipe on the map. In step 217, a water treatment process diagram is displayed separately from the map, and in step 218, the R value, water quality data, and process data at the date and time when the target water passes through the CCP are displayed.

  In this example, the R value is mainly used as the information to be displayed, but in addition to this, water quality data, process data, raw water quality, water quality test results at the nearest water tap, etc. in processes other than CCP and CCP are shown. May be. Further, the display of the R value may be displayed on the map for all the R values, or the R value may be displayed limited to a certain range, for example, one or more ranges.

  Thereby, the display means 70 of FIG. 1 displays the information acquired by the display information selection means 43 on the map recorded in the geographic information storage means 34.

  On the other hand, the data editing means 80 in FIG. 1 is used when inputting or correcting water quality data, process data, water distribution data, diagnosis rules, and geographic information. Specifically, it will change hazardous substances and set values associated with changes in raw water quality and water purification processes, change distribution pipe data by renovating and laying pipes, and changing customer information.

  FIG. 3 is an example of a screen displaying a hazardous substance concentration prediction according to an embodiment of the present invention. The display screen 300 displays R values for hazardous substances having a risk of carcinogenesis in a specific area. The magnitude of the R value is displayed on the map as shades 301, and the maximum value, minimum value, and average value within the district extracted in the map are also displayed as a specific numerical value in Table 302.

  FIG. 4 is an example of a screen displaying the concentration change of the hazardous substance in the target water as the water history display according to another embodiment of the present invention. The display screen 400 shows on the map how the R value of the carcinogenic substance in the water supplied to the set date and place changes in the supply route. The R value is displayed only in shading, but a numerical value may be written together.

  According to these embodiments, management of the water supply facilities by HACCP management is streamlined, and necessary and sufficient information covering the hazard items and their temporal variations and their geographical distribution is provided to water consumers, water utilities. And to the maintenance company. Specifically, when the water that is sent to each consumer, which changes every moment, causes harm to the consumer or the possibility of such harm, it is not a simple trend information management for each measurement value. Water quality data and process data in the process having the above importance are used. These data and facility and customer geographic information are used to trace the possibility of water contamination against water that creates or is likely to cause harm. For example, trace the processing operation status such as coagulation sedimentation, filtration, disinfection, etc., and the possibility of water contamination due to ongoing piping work. By clarifying the state of water quality change in the route on the map of tap water obtained in this way, it will be easier to understand the cause of the occurrence of harm or the possibility of harm to consumers, and accountability to consumers Can be fulfilled.

It is the example which displayed the passage date, monitoring data, and R value of CCP of the selected harm for the target water. In this example, the information extracted by the display information selection means and the geographic information are associated with each other, and the information extracted from a plurality of facilities is displayed in the order of the facilities existing on the map. Therefore, it can be recognized as information similar to the case of displaying on the map for a water consumer who sees the screen.

  FIG. 6 is a screen example in which a history of water is displayed on the display screen 600 of the display means 51 according to another embodiment of the present invention. As the water history display, the process, water quality data and concentration analysis results regarding the target water are displayed as trends. The date and time when the target water passes through each process, and the process of CCP are shown. Also in this example, the information extracted by the display information selection means and the geographic information are associated with each other, and the information extracted from the plurality of facilities is displayed in the order of the facilities existing on the map. Therefore, it can be grasped as information similar to the case of displaying on the map for a water consumer who sees the screen.
