Drainage pump operation control and management system.

In general, the urban management system is designed to solve the local flood damages. As a method to improve the pipelines lacking the capacity of water supply, there is a method of increasing the flow rate by rushing the slope of the pipeline, And a method of expanding the area.

However, most of the improvements to the existing pipelines are not possible due to the existing underground facilities (waterworks, city gas pipelines, telecommunication, electricity, etc.) and structural improvements for improving the slope of existing pipelines Which is not only a huge cost but also a lot of complaints.

As a result, there are measures to install stormwater storage facilities and bypass pipelines, but there are also problems such as civil complaints, many compensation expenses, and construction time lengthened due to traffic volume.

Conventional techniques for solving such problems include a method of efficiently running the pump of the drainage pump station by predicting the amount of inflow to the drainage lane through a program that measures the level of the pumpage drainage lid, .

However, even in the case of the pump operation method using the rainfall measurement and the water level detection, the flooding situation is still frequently occurring due to the fact that the rainfall does not reach the drainage pond (pump station) .

FIG. 8 is a schematic view showing an installation example of a smart drain pump exemplified for explaining an operation of calculating an appropriate pump RPM value by a pump operation algorithm. As illustrated in the figure, the natural descent is performed by the inclination of the drain pipe, It will be possible to calculate the appropriate RPM based on the discharge volume based on the pump RPM so as to smoothly drain excess flow by converting the excess water depth into the flow rate.

For example, when the discharge amount Q, the cross-sectional area A, and the diameter D according to the RPM are 125 mm in the installation state as illustrated in Fig. 8,

Discharge amount (Q) = A (cross sectional area) * V (flow rate)

Cross-sectional area ^{(A) = πD 2/4} = π * (0.125) 2/4 = 0.01227 (m 2)

V = 1 / n * R ^2/3 * S ^1/2

to be. (Where n is the value of 0.015 (empirical value) as the roughness coefficient, R is the mean diameter, and S is the slope).

The radius (R) is R = A / P, A is the cross-sectional area of the channel, P is the circumference,

P =? D- (D / 2) *? = D (? - (? / 2)).

The pipe diameter (D) is 0.125 m, and θ is a value for setting the water level of the pipe. In the case of 360 degrees, the pipe is empty. When the pipe is 0 degree, the pipe is full. As a result, the cross-sectional area A can be estimated to be 0.01227 m 2, and the margin P can be calculated to be 0.393.

The slope (S) is S = (h1-h2) / L where h1 and h2 are the elevation values of the channel inlet and outlet, h1 is 0.74 as an initial value 0.05 (arbitrary value for test) H2 is fixed to zero. At this time, the tube length (L) is set to 100 m.

The water depth (d) in the pipeline is calculated using the following formula.

d = D / 2 * (COSθ / 2 + 1) + h n 1 -h 0 1

Here, the pipe diameter (D) is 0.125 m, h ⁰ ₁ ? Is increased to 0.05 (an arbitrary value for the test) by setting an initial value of 0.74 as an elevation value of the pipe inlet portion to the forced drainage depth of the pump, θ is a value for setting the water level of the pipe. When the pipe is 360 degrees, the pipe is empty. When the pipe is 0 degree, the pipe is full.

As a result, the table of FIG. 9 is summarized based on the inlet depth value. Also, it is possible to select an appropriate RPM for the flow rate based on the discharge amount set value according to the RPM.

According to the present invention, it is possible to improve the flow rate by using the smart drain pump without improving the existing pipeline and improve the piping capacity, thereby improving the situation where the drainage pumping station can not be reached, So that there is an advantage that the local flooding can be improved.
