The problem of this system is that it requires a lot of energy and cost for transportation and treatment of water. There is a problem.

That is, in the past, most of the systems have installed water treatment facilities for using water resources such as rivers, dams, reservoirs, etc., which can secure a large amount of water, and supply water from a water treatment facility to a water treatment water use place . According to such a conventional water treatment system, in order to simultaneously supply treated water from a large-scale water treatment facility to various places of use, not only the installation cost of the pump facility, the piping facility, the reservoir, There is a problem in that the environmental load is largely generated depending on the supply box and the energy efficiency is low.

In addition, the conventional water treatment and distribution system is a one-way supply system using water runoff. It is used for water treatment in accordance with the standards of drinking water, regardless of the water quality required for use, . Thus, water treatment is performed on the basis of drinking water irrespective of the place of use, and the facility cost, processing cost, and transportation cost for securing water resources increase more than necessary.

Conventional water treatment and distribution systems that make facilities such as large-capacity dams and supply them in one direction at a remote location in a remote area, even though water resources such as large and small river water, rainwater, sewage, ground water and sea water exist in each area, are inefficient, Waste is a big problem.

[ The third image reading unit 133 compares the received photographed image with a normal reference image, and reads out an abnormality or abnormal symptom of the photographed portion. Upon detection of an abnormality, the third image reading unit 133 transmits the image and abnormality detection information to the integrated management server 90.

The transit route monitoring unit 140 is for detecting an abnormality or an abnormal state of the water supply route. The monitoring unit 140 may include a ground path monitoring unit 141 for monitoring a transmission path disposed on the ground and an unexposed path monitoring unit 143 for monitoring a water path laid under the ground or underwater . 4, the ground path monitoring unit 141 includes a photographing unit 141a for photographing the ground path 41 located on the ground, a photographing unit 141b for photographing the ground path 41 photographed by the photographing photographing unit 141a And a fourth image reading unit 141b for reading the image. The photographing unit 141a is provided to photograph the ground path 41 located on the ground, and may include a surveillance camera installed every predetermined interval, preferably a surveillance camera having a zoom-in function and a pan-tilting function It is good to do. Therefore, a surveillance camera is installed and photographed mainly on important points or dangerous areas, and the photographed image is transmitted to the fourth image reading unit 141b. The fourth image reading unit 141b compares the image photographed by the photographing unit 141a with the reference image to determine whether the image is damaged, damaged or deformed. In addition, it may be possible to detect changes in the natural environment or other risk factors that may affect the water supply and drainage in hazardous areas. For example, if a natural terrain deformity due to a typhoon, heavy rains, heavy snow, or other dangerous materials (rock, wood, other garbage, etc.) is caught or raised on the water supply route, And transmits the anomaly detection information and the corresponding image to the integrated management server 90.

The unexposed path monitoring unit 143 is for detecting an abnormality or an abnormal symptom of the buried underground waterway path 43. The unexposed path monitoring unit 143 monitors a frequency And a frequency reading unit 143b for analyzing the signals sensed by the frequency sensing unit 143a. The frequency sensing unit 143a is installed every predetermined interval of the underground waterway path 43 and is preferably connected to the frequency readout unit 143b installed on the ground so as to surround the underwater waterway path 43. [ The frequency reading unit 143b reads the frequency sensed through the frequency sensing unit 132a, and reads out the abnormality of the underground waterway path 43 for each predetermined interval. The reference frequency for each flow rate of the process water flowing through the underground water path 43 controlled by the integrated management server 90 is set and the frequency detected by the frequency sensor 143a is compared with the set reference frequency, And transfers the read result to the integrated management server 90. [ Therefore, when a leak occurs due to a crack or the like occurring in the underground water supply path 43, a change in the frequency is detected to detect an abnormality of the underground water supply path 43 buried in the underwater path 40 The status can be confirmed and reflected in the process water supply operation plan.

The connected-channel network monitoring unit 150 is also for detecting abnormalities or abnormalities of the connected-channel network, like the water-supply-path monitoring unit 140. The linked channel network monitoring unit 150 can monitor each of the non-display connection channel networks installed on the ground and the non-display connection channel networks embedded in the ground similarly to the transmission / reception channel monitoring unit 140, A detailed description thereof will be omitted.

5, the accident prediction monitoring unit 160 includes a weather forecast information collecting unit 161 for monitoring weather forecasts, a filtering unit 160 for filtering key information among the information collected by the weather forecast information collecting unit 161, And an accident trigger weight generation unit 165 for analyzing the information filtered by the filtering unit 163 and the filtering unit 163 to generate an accident trigger weight.

The weather forecast information collection unit 161 can acquire regional weather forecasts from a server 220 of an affiliated organization that performs weather forecasts, for example, from a weather station server or the like, and also provides major weather forecasts announced by other similar agencies, for example, , Storm warning, storm warning, storm warning, flood warning, landslide warning, lightning warning,

The collected weather forecast related information is transmitted to the filtering unit 163. The filtering unit 163 filters and selects major weather forecasts (such as plate wave related information, typhoon related information, flood warning, regional landslide warning, and lightning warning) for giving images to the waterworks management facility from among the delivered weather forecast related information , And the remaining weather forecasts are noise processed. The main weather forecast information filtered by the filtering unit 163 is transmitted to the accident trigger weight generation unit 165. The accident occurrence weight generation unit 165 divides the major weather forecast information by region and generates a weight by judging the possibility of causing an accident for each water service related facility installed in each region. For example, in the case of a cold weather warning, the weight is set to 1 at minus 5 degrees to 10 degrees, the weight 2 at minus 10 degrees to minus 15, the weight 2 at minus 16 degrees to minus 20 degrees, and the weight 3 at minus 21 degrees Can be generated by increasing the trigger weight. The generated accident-induced weights are transmitted to the integrated management server 90. In the integrated management server 90, in accordance with the dynamics control process reflecting the incident-induced weights transmitted, the operation management plan is modified .

In addition, the accident prediction monitoring unit 160 can collect information on the uninterruption status and the unstoppable schedule for each region from the KEPCO (power supply agency) server. The information gathered thus can reflect the occurrence of downtime and the information on the downtime for each region in the operation plan.

In addition, it is preferable to install the emergency generator in each regional facility in preparation for the occurrence of a power failure at a regional operation facility, and to supply power generated from the installed emergency generator with priority. For example, it is advisable to supply the treatment water in the order of low storage capacity of the treated water for each facility, or set the power supply priority so that the treated water can be processed.

According to the above configuration, the monitoring results of the respective facilities acquired by the emergency situation monitoring unit 100 are transmitted to the integrated management server 90. The integrated management server 90 applies the received monitoring result to the system dynamics control process, and reflects the monitoring result in the operational plan so that the best operational state is maintained. For example, when it is detected by the water treatment plant monitoring part 120 that a problem has occurred in the treatment facility of the water treatment plant 20 in a specific area (area A), the integrated management server 90 determines, It is possible to increase the throughput in the water treatment plant in the adjacent region (B region) by increasing the processing capacity in the water treatment plant 20 in the vicinity of the treatment plant 20, And to further supply water to the water treatment plant in area B. Therefore, the water treatment plant 20 of the A region can reduce the driving load, thereby preventing the deterioration of the condition, and the supply amount of the treatment water that can be scarce can be treated in other regions.

In addition, when the emergency management server 90 confirms the occurrence of the emergency situation or receives the expected information from the emergency monitoring apparatus 100, the integrated management server 90 delivers the information to the manager terminal 210 of the facility, You can check the status immediately so you can take follow-up action.

In other words, the integrated management server utilizes the buffer function of the reservoir based on the demand forecast, establishes the appropriate operation plan, and provides the intelligent distribution and supply by providing the established operation plan for each facility.

As described above, according to the SD-based multiple water source water loop number management system considering the abnormal situation of the present invention, it is possible to easily obtain the raw water by taking multiple water sources that can be secured in each of the various areas, By blending the raw water with the treated water, supplying treated water to the use area of the area or by providing mutual supply or supply distribution equipment in connection with other areas, it is possible to prevent water shortage and efficiently supply water. have. That is, there is no need to equip a large-scale water intake facility, a storage facility, and a water purification facility at a remote place as in the prior art, and a small-capacity facility can be installed for each region. Therefore, a facility cost is reduced and a large- It is possible to use not only the installation cost but also the operation cost.

In addition, by monitoring the status of each facility by real-time monitoring, it is possible to predict the occurrence of an emergency situation and an emergency situation, and apply it to the system dynamics control process. By applying the minimum environmental load and operating energy, optimal water treatment and distribution can be performed, And can effectively supply water.

Meanwhile, in order to operate the system according to the dynamics control process, a model for the system is established and modeled, and a control process is derived and applied to the system operation. To this end, an example of a modeling process of the multi-source intelligent distribution and supply system will be described.

First, the computer model using system dynamics consists of three basic elements called storage variables, flow variables, and transformers, and simulates the temporal change of the system by expressing the relationship between these elements in the form of finite difference equations.

The storage variable represents the amount accumulated in the system at the time, the flow variable represents the amount of change of the storage variable during the unit time, and the converter is used to represent the rate of change of the flow variable by the value of the storage variable.

The mathematical meanings and algorithms for the interrelationships of variables in the system dynamics model are as follows.

If there is a function of L = f (I, a, b, R (iR, oR)), the relation between the storage variable and the flow variable is defined as follows.

Where L is the level variable, R is the rate of change variable, iR = inflow, oR = outflow, t = time (t), 0 = initial time.

If equation (1) is differentiated with respect to time t, equation (2) is obtained, which is a relational expression of the storage variable and the flow parameter.

Here, iR (t) = a 占 L (t), oR (t) = b 占 L (t)

The following equation (3) is a spin equation combining the equations (1) and (2) and is a mathematical algorithm of the system dynamics simulation model equation.

Next, the causal map is a method for analyzing the characteristics of the system under study. The causal relationship between variables is represented by using the + and - signs and arrows. The +, - (+) Or negative effect (-) on the change of other variables.

FIG. 6 shows an example of a causal relationship. When the number of births increases as the number of births increases and the number of births increases as the number of the population increases, the behavior of the population increases as the feedback loop (self- , And a model of reduced population as the number of deaths increases as population increases, and the negative feedback loop (target-oriented feedback, stabilization feedback, self-suppression feedback) dominates as the number of deaths increases.

Next, a model for modeling is established.

The components of the system are divided into five categories: stock variable, flow variable, converter variable, time variable, and action connector. A flow diagram is created to show the relationship and the feedback loop. The process of transforming the variables into integral and differential equations and mathematical or logical equations is described as the formulation of the model. , Figure 7 shows the variables and meanings of the tools used to create the system flow diagram.

A model for modeling is established, and a computer simulation using system dynamics is verified through a process as shown in FIG.

FIG. 9 is a simple example of system dynamics, showing a causal map for a system in which a gravity outflow occurs in a reservoir and an example of implementing the system using STELLA. FIG. 10 shows a finite difference equation of a reservoir system dynamics model .

The model is established and validated through a series of validation methods (model structure, model type, policy implication), verification and calibration.

The model shown in FIG. 11 is a model for a hypothetical water supply system, and includes basic components of a multi-source water supply system, that is, a water supply facility, a water intake facility, a house water supply, a water treatment facility, a water supply facility, a reservoir and a pumping facility. Models of facilities are modularized, so that it is easy to modify and expand the model through the combination of modules even if the object of modeling is changed. In addition to the basic water flow, it is possible to estimate the pumping and water treatment costs incurred during the operation of the system, and to determine the amount of water withdrawal by water source according to the variation of the water quality of multiple water sources, , It is also possible to simulate the water level of the reservoir according to the reservoir pumping rule and calculate the pumping cost accordingly. However, the modeling range developed is from the water supply system to the reservoir, and the modeling of the water flow and pressure of the drainage network after the reservoir is not included.

The input information and data required for the development of the multi - source operational system dynamics model are as follows.

  - Suwon: Initial water level of each water source or water availability (water availability), initial water quality, pollutant load by water source

  - Water treatment plant: Initial water treatment capacity of water treatment plant, treatment capacity of water treatment facility, water treatment cost according to pollution load

  - Connection pipeline between facilities: diameter, length, material, etc.
