It can be transmitted to the control unit 160 to determine whether there is a discrepancy between the supply and demand of water resources flowing through the waterway, and to verify the actual usage of water resources.

On the other hand, the water resource measurement and management system 100 according to the present invention uses the terminal 110 provided with a smart phone to observe a specific area for a certain time and take an image of the water depth target 120, but over time In order to photograph whether or not the water level has changed, the terminal 110 must be able to be maintained in a constant posture for a long time, and power must be continuously supplied.

In addition, it is possible to determine whether to use the self-power of the terminal 110 or the charging power of the solar module 130 in conjunction with the weather information.

The terminal 110 may exhibit a zoom-in/zoom-out function according to the flow rate of the water resource W flowing through the water channel 210 or whether lighting is used. When the flow rate is high, the scale of the depth target 120 may not be accurately photographed due to water droplets generated while the water depth target 120 obstructs the flow of water. When the terminal 110 determines that the flow rate of the water resource W is faster than the reference value, it may operate a zoom-in function to enlarge the scale of the water depth target 120 and take a picture. You can use the zoom in function even after cloudy weather or after sunset. When the flow rate of the water resource (W) reaches the standard value or less or when sunrise occurs, it can return to the zoom-out function.

In addition, the terminal 110 may photograph the water surface of the water depth target 210 and the water channel 210 by using the time lapse function of the camera (photographing unit, 111 ) provided in the terminal 110 . The water resource measurement management system 100 according to the present invention measures the water level using the water level measurement sensor 134 or photographing the water depth target 120 with the photographing unit 111 of the terminal 110 for a long time. Therefore, the image of the depth target 120 taken by the photographing unit 111 is generally in the form of a moving picture rather than an image of a single cut. However, the running time of a moving picture taken according to the lapse of time is inevitably long, and it may take a lot of time to read the image. Therefore, in the water resource measurement management system 100 according to the present invention, the photographing unit 111 applies the time-lapse function to photograph the water depth target 120, thereby reducing the time taken for reading and reducing the capacity of the image.

5 and 6 exemplarily show a waterway network in which the water resource measurement management system 100 according to the present invention is installed.

Referring to FIG. 5 , water resources (water) stored in the water source hole 201, such as a reservoir, are supplied to the beneficiary area (Montridge) through the trunk line 210 and the branch line flow path 230 . Here, the trunk line 210 means a water channel directly connected to the Suwon hole 201 , and the branch channel 230 means a channel branched from the trunk line 210 .

A flow meter 220 may be installed in the trunk line flow path 210 and the branch line flow path 230 . However, since the water resource measurement management system 100 according to the present invention interprets the captured image of the terminal 110 provided with a smart phone or calculates the flow rate from the water level value measured by the water level measurement sensor 134, the flow meter ( 220) is preferably used for verification or auxiliary purposes. For example, by comparing the flow rate calculated by the terminal 110 with the value measured by the flow meter 220 to reduce the error, or use the measured value of the flow meter 220 when the terminal 110 is out of order to manage water resources.

The value measured by the flow meter 220 may be transmitted to the cloud server 140 or the water management control unit 160 .

In the case of FIG. 5 , the depth target 120 , the terminal 110 and the solar module 130 are between the front end of the Suwon hole 201 , the branch line 230 , and the rear end of the branch where the branch line 230 diverges. It may be installed in the bow path 210 . The water resource measurement and management system 100 according to the present invention may determine whether the supply of water resources is properly performed by summing the flow rates (Q1, Q2, Q3) measured at each point. That is, if the combined flow rate of Q2 and Q3 is the same as Q1, it can be determined that there is no leaking or lost water resource, but if Q1 is larger, it is judged that a leaked or lost water resource has occurred, and it is guided to find and solve the cause.

6 shows a branch path 230 leading to the beneficiary 202 . A flow meter (not shown) is also installed between the branch line 230 and the beneficiary 202 to measure the flow rate of water resources actually flowing into the beneficiary 202 .

As described above, the water resource measurement management system 100 according to the present invention is a cloud-type portable water measurement management system using a smart phone, which can reduce operating costs and has a predetermined time interval for a number of points requiring water level measurement. It is easy to implement a system that can collect measurement data at the same time for a specified period of time.
