6, the water information management server 500 includes a scenario generation unit 510, a scenario database 520, a simulation unit 530, and a monitoring unit 540.

The scenario generating unit 510 generates a local water supply / demand scenario considering the multiple water sources and stores it in the scenario database 520. To this end, the scenario generating unit 510 recognizes the water supply abnormality in consideration of the demand amounts of domestic water, agricultural water, and industrial water.

In one embodiment, the scenario generator 510 recognizes a water supply-water purification-water supply abnormality associated with a customer.

In another embodiment, the scenario generator 510 measures the flow rate of multiple water sources available in the area. At this time, the scenario generating unit 510 links measurement information of multiple water sources using a plurality of collecting devices (for example, a three-point automatic flow meter, an image reading type water level meter, etc.).

In addition, the scenario generating unit 510 generates a scenario for a countermeasure against a water shortage based on the data of the remote collector or the remote controller received from the monitoring unit 540, and stores the scenario in the scenario database 520.

[ At this time, the countermeasure plan may include the necessary water withdrawal amount due to an emergency situation or a drought, information on emergency water quantity, and the like.

The scenario database 520 stores a water scarcity scenario for multiple water sources. In the water shortage scenarios using multiple water sources, countermeasures according to the types of water are stored as shown in [Table 1].

In other words, the management stage is classified according to the supply amount with respect to the demand amount for the multiple water resources. For example, as shown in [Table 1], 80% ~ 90% of the demand for multiple sources is classified as the stage of interest. If the supply is 60% ~ 80% of the demand, 50% ~ 60% is classified as boundary step.

Scenarios for the domestic water supply corresponding to the stage of interest should be provided in the normal supply and water conservation promotion, and scenarios for industrial water supply should be supplied in a normal manner, water conservation promotion should be promoted and reuse water utilization should be expanded. Promote and reduce some of the river maintenance water when necessary.

The scenarios for the living water corresponding to the state of the state are the public water supply aiming at the normal supply of domestic water but the reduction of 10% or more, and the adjustment of the operating hours of the water use shops (for example, car wash, bath, swimming pool, etc.) To expand water saving in public buildings and large buildings, to expand the use of water for emergency water use, to stop the use of water for cleaning water, to maintain water, and to provide water conservation promotion.

The scenarios for industrial water corresponding to the stage of Caution are to maintain the normal supply but shorten the plant operation and provide water conservation promotion. Scenarios for agriculture corresponding to caution phase maintain normal supply but reduce some of river water (eg, 20%) and provide water conservation promotion.

The scenarios for domestic water corresponding to the boundary stage recommends the autonomous closing of water use shops (for example, car wash, bath, swimming pool, etc.), declares drought-hazardous areas for the entire area, (For example, 20%), water supply limited on a day or three-day basis, supplies bottles and water supply vehicles of necessary living water, utilizes the priority of domestic water for agricultural groundwater and provides water conservation promotion do.

The scenarios of industrial water corresponding to the boundary stage recommend water shortage or temporary shutdown of large-scale use plants and provide water conservation promotion. Scenarios for agriculture that correspond to the border stage provide priority supply of water supply to urgent crops, minimize supply of river water supply and promote water conservation.

The simulation unit 530 simulates the scenario stored in the scenario database 520. [

For example, regarding scenarios for water welfare (cost aspect) stored in the scenario database 520 as shown in [Table 2] below, in usual times ① measurement of water source ② acquisition of water use plan ③ estimation of demand amount ④ calculation of available water quantity ⑤ selection Water intake ⑥ Water treatment process ⑦ Measuring water level of drainage pond ⑧ Optimizing pump operation ⑨ Measuring flow and pressure in pipe ⑩ Leaking water management ⑪ Measuring usage ⑫ Managing pipeline statistics ⑬ Charging management ⑭ Execute in order to share customer application information However, Short-term water supply and demand evaluation ② Water shortage prediction ③ Selection of response scenario ④ Demand forecast ⑤ Estimation of available water quantity ⑥ Selective water intake ⑦ Operation of recombined water treatment process ⑧ Execute in order of deriving additional water supply status relative to demand quantity.

In the above embodiment, the monitoring unit 540 generates and provides a graph for comparing past data (for example, yesterday data) and current data (for example, today data), and generates a specific pattern graph for each unit . At this time, the pattern graph includes maximum, minimum, average, and analysis data.

In another embodiment, the monitoring unit 540 monitors the position and installation status of the pressure gauge based on the image map.
