Description

Water Level Control Automation Method of Water Tank

The present invention relates to a method and system for automating the water level control of a water tank, and more particularly, such as constant water, leachate, or wastewater including groundwater (hereinafter referred to as raw water). A method for automatically adjusting and controlling the water level (or amount) of raw water stored in the water tank after the water is passed through the water pipe from the point where it exists) to the desired desired water tank.

Conventionally, a water level control device installed in a predetermined area for storing raw water into a water tank is pumped through a water tank installed at a predetermined distance by pumping raw water from a predetermined reservoir or reservoir or underground to a water tank and supplying water. The tank detects the amount or level of raw water stored in the sensing means and transfers it to the controller through a wired wire, and the controller determines the detected signal to control the driving of the pumping means.

However, conventionally, a water pipe for supplying raw water and a wire for transmitting a detection signal are simultaneously buried underground or wires must be connected separately in a processed state, thus requiring double connection work, and processing or buried wiring. Since there is a high possibility of disconnection, short circuit, or leakage due to external influences or conditions, there is a problem that raw water stored in the water tank overflows when the controller cannot transmit a normal control signal to the pumping means. In addition, if the pumping means is always operated in an operating state, the durability of the pumping means is reduced, which has the disadvantage of shortening the life, and the electric wire as well as the loss of leakage or leakage of electric power due to disconnection, short circuit or leakage, electric shock Problems that could cause accidents were also inherent. In addition, since the separate wires are wired, the cost of installing and maintaining the water level regulator was also increased.

In view of such a problem, the applicant of the present invention automatically removes the wiring connected to the wire and installs a pressure sensing means wirelessly detecting the water pressure formed in the water pipe at one end of the water pipe, and automatically measures the amount or level of raw water stored in the water tank. It has been applied for a wireless automatic level control system that can solve the problems caused by the wiring by adjusting, and can adjust the water level more accurately.

However, in the conventional wireless automatic water level control system, the water level is set in advance in order to automatically adjust the water level of the water tank at the beginning, and then the raw water is stored in the water tank by the intake of pumping means, and the raw water is stored in the high water level. When the pumping means is stopped, in this case, after the predetermined time elapses, the detected value is reset to a high water level, and a method of resetting a predetermined pressure value or less from the set high water level to a low water level has been applied.

Therefore, in the case of the conventional wireless automatic water level control system, when the raw water is stored at the initially set high water level, the high water level is reset, and when the water level is discharged again, the high water level is reset to high water level. In other words, the high water level can be reset repeatedly. In addition, by resetting the pumping means by setting the water level value below the predetermined pressure to the low level for each high water level to be reset so that the raw water is stored again in the water tank.

In the case of setting the high water level in the conventional automatic water level control method, if a predetermined pressure is detected by the pressure sensing means for a predetermined time, it is reset to a high water level. In this short case, it is not easy to set a more accurate high water level because the shaking value in the water tank is reset to the high water level at the high water level.

In addition, even in the method of setting the low water level, the pressure or pressure value set from the high water level is set to the low water level so that even when the low water level is detected, the water in the water tank may wait for a predetermined time or when the low water level is set. Even there was a problem that it is not easy to set a more accurate low water level.

The present invention is to set the high water level and low water level of the raw water stored in the water tank by solving the above problems, and the shaking of the raw water after the high water level to more effectively reset the high and low water level of the raw water in the water tank It is an object of the present invention to provide a method for automatically adjusting the water level of the water tank to more precisely set a slight change and to minimize and reset a small water level even when the water level is low.

In addition, the present invention detects and determines the intake or stoppage or retake of raw water according to various water pressure changes formed through the water pipe from the intake of raw water, and resets it by comparing with the initially set value, such as intake from a water well or a pressurized field. Another objective is to provide management convenience by minimizing the management and maintenance of the raw water and to enable more intelligent water level adjustment and control.

Raw water stored in the water tank 300 is discharged or pumped into another water tank through a separate water pipe or discharge pipe.

The driver controller 110 processes and outputs electrical data input from the pressure sensing means 34. The driver controller 110 converts the data into digital signals to minimize the loss of signal lines of the pressure sensing means 34. It is to.

The main controller 100 is for monitoring, controlling and displaying various situations of the system. Referring to the system block diagram of FIG. 1, the main components of the main controller 100 and the driver controller 110 are shown.

That is, the power supply unit 10 of the main controller 100 outputs the AC power AC220V input from the outside or converts the DC power to DC power, and the power supply unit 10 outputs the surge voltage of the input AC power. Alternatively, after the noise is blocked, the pumping means 22 is directly connected to or outputted by stepping down, rectifying, and smoothing a DC power of a predetermined size for driving an electronic circuit configured in the controller 100.

The control panel unit 12 sets the driving of the pumping means 22 and displays the driving state. The control panel unit 12 is mounted on the front surface of the main controller 100 and has electric and electronic circuits for controlling the system. . The control panel unit 12 allows the user to recognize and control the information regarding the setting and the state of the mode related to the driving of the pumping means 22 at a glance.

The controller 16 determines the input signal set by the control panel unit 12 and outputs the signal to the control panel unit 12 again or outputs a signal for controlling the driving of the pumping means 22. Contains a program for control, and microcomputer is preferably applied. The control unit 16 is composed of, for example, A, B contacts and common contacts to control the pumping means 22.

The memory unit 18 outputs set data or stores input data. The memory unit 18 outputs a program or data set at the request of the controller 16 or stores information data input from the outside.

Interface unit 112 for digitizing the main controller 100 and RS-232C communication, and a display unit 114 for displaying the state of the driver controller 110 is included.

Referring to the automatic water level adjustment method of the water tank of the present invention configured as described above, it is as shown in the flowchart of FIG.

First, according to the present invention, after installing the water level control automation system of the water tank in the first step (S10), various initial values relating to the water pressure of the raw water stored in the water tank 300 in advance to the memory unit 18 Will be set. That is, when the installation of the system is completed, the high water level, low water level, reference value, stable value and average value of the raw water to be stored in the water tank 300, time and cycles are set in advance.

In the second step S11, the pumping means 22 is driven by the control of the main controller 100 for the initial intake from the intake well 24. At this time, the control signal is applied from the main controller 100 to the electronic switch 17 by the user's operation so that the driving power is applied to the pumping means 22. Therefore, when the water is drawn from the pumping means 22 of the water intake well 24, the raw water is made into the water tank 300 through the water pipe 36.

In the third step (S12), the raw water taken by the pumping means 22 is supplied to the water tank 300 through the water supply pipe 36, and the initial value set after pumping from the pressure sensing means 34 in the water supply pipe 36 From it, it is determined whether the change in the water pressure satisfies the set first condition. The first condition is a stable value s1 set in FIG. 8 for a predetermined time t2, for example, 1 second to 5 minutes, preferably 30 seconds, for example, +0.01 to +0.5 kg / cm ² , preferably. For example, + 0.02kg / cm ² is maintained. At this time, the average of the sensed stable value s1 is set as the initial value. The predetermined number of times (eg, 2 to 32 times, preferably 16 times) can be counted during the predetermined time. In addition, when the detected value for a predetermined time t2 is maintained for a predetermined time t2, for example, +0.5 kg / cm ² or more, the pumping means 22 is turned off, which is an on / off valve 32. ) Is locked or the abnormal pressure due to freezing of the water pipe 36 rises, thereby stopping the driving of the pumping means 22 to prevent excessive load on the pumping means 22.

In addition, the bypass pipe 37 when the change in the water pressure detected after the first condition is constantly lowered to a predetermined pressure s2, for example, -0.01 kg / cm ² or less for a predetermined time t2. It is judged that the use of the raw water by the opening and closing of the valve 38.

Referring to FIG. 8 as a graph of detecting a change in water pressure of the pressure sensing means by the water tank level adjusting method of the present invention, it is shown in Table 1.

Pressure value Explanation P0 On point of initial pumping means P1 Maximum pressure sensing after initial pumping P2 Pumping stability and initial value setting P3 High water level setting P4 Pump off means to high water level P5 Low water level setting P6 Set low water level and pumping restart

In addition, Table 2 is a description of the hydraulic pressure change between the pressure values of Table 1.

Pressure value Explanation P0-P1 Initial pumping pressure rise section P1-P2 Initial Normal Pumping Section P2-P3 Section for resetting high water level with normal pumping where pumping means and water supply pressure are formed P3-P4 Stopping section of pumping means due to high water level P4-P5 Variable pressure range due to altitude difference between water well and water tank P5-P6 The actual water level detection section on the water pipe and the consumption and retake section of raw water

As described above, in the graph of FIG. 8, the change in the water pressure sensed by the pressure sensing means 34 is the initial water pressure P0 for driving the pumping means 22 through the main controller 100 to initially take in the raw water. ), A first water pressure P1 which is the highest pressure sensed after the pumping means 22 is pumped, a second water pressure P2 which is an initial average value at which the pumping is normally stabilized after the pumping means 22 is pumped, A third water pressure P3 at which the water level of the water tank 300 is reset to a high water level value, a fourth water pressure P4 at which the pumping means 22 is stopped after the high water level is reset, and the pumping means 22 is stopped. After the low water level is set, the fifth water pressure P5 at which the low water level is set, and the sixth water pressure P6 at which the pumping means 22 is restarted as the low water level is set.

In addition, as shown in the graph of FIG. 8 in the third step (S12), when a sudden hydraulic pressure is applied between the first hydraulic pressure P1 and the second hydraulic pressure P2, the water pipe 36 is blocked or opened due to a foreign matter. When the valve 32 is locked, or freezes, etc., the pumping means 22 is stopped and an alarm is generated after comparison with a previously set value.

That is, when the change in the water pressure sensed between the first water pressure P1 and the second water pressure P2 is equal to or greater than a predetermined pressure (for example, 0.5 kg / cm ² ) for a predetermined time, it is determined that the valve is closed or frozen. The driving of the pumping means is stopped.

The initial water pressure P0 due to the initial pumping gives a predetermined waiting time t1 so that the water pressure detected from the pressure sensing means 34 is ignored. This is to prevent the pumping means 22 from being stopped when the water pressure detected by the pressure sensing means 34 is higher than the average value or the high water level stored in the main controller 100.

Next, when the first condition is satisfied in the fourth step S13, the average water pressure satisfied is reset to an initial value. The reset value is stored in the memory unit 18 and used as a comparison value when the next initial value is reset. When the reset initial value is input again, this value is stored.

In a fifth step S14, after the initial value is reset, a change in water pressure is sensed to determine whether the second condition is satisfied from the set initial value.

In other words, the second condition is a predetermined time t3, for example, 1 second to 5 minutes, preferably 30 seconds for a predetermined number of times, for example, 2 to 32 times, preferably 16 times of the set reference value a1, for example. , -0.01 to -0.1kg / cm ² , preferably -0.03kg / cm ² . The second condition is that the raw water is stored in the water tank while detecting and determining whether the water tank is a set high water level, thereby setting the actual high water value.

In addition, when the change of the water pressure is satisfied to the initially set reference value a1 at a predetermined number of times c1 during the predetermined time t3, the same time t3 is detected when the set reference value a1 is not satisfied. While detecting the same number of times c1 continuously, and when the set reference value a1 is met, a predetermined number of times c4, e.g., 1 second to 5 minutes, preferably 10 seconds, For example, it detects whether the reference value a2 is initially set 2 to 32 times, preferably 16 times, and when the reference value a2 is not satisfied, the predetermined number of times (t3) is again performed. It is detected whether the reference value a1 set by c1) is satisfied. This is a condition for setting the high water value by judging the change in the water pressure more actively.

Further, the reference values a1 and a2 can be set to an initially set average value, and in the second condition, the average value of the change in the water pressure is set initially at a predetermined number of times c1 for a predetermined time t3. while detecting whether it meets the a1), and while detecting whether it meets the initially set average value a2 for a predetermined number of times c2 if the set average value a1 is satisfied. Shake wave values (± 0.03kg / cm ² ) are ignored. This makes it possible to ignore undesirable changes in the water pressure delivered from the wells and water tanks to the water pipes.

In addition, when the second condition is satisfied in the sixth step (S15) and (S16), it is reset to a high water level value and the pressure sensing means 34 detects whether the change in the water pressure satisfies the third condition. 3 The condition is a stable value s3 set for a predetermined time t5, eg 1 second to 5 minutes, preferably 30 seconds, eg +0.01 to +0.1 kg / cm ² , preferably +0.03 kg / This is the case when it is kept at cm ² or more. The predetermined number of times (eg, 2 to 32 times, preferably 16 times) can be counted during the predetermined time.

Therefore, when the third condition is satisfied in the seventh step S17, the driving of the pumping means is stopped.

After the driving of the pumping means 22 is stopped in the eighth step S18 and S19, it is determined whether the change in the water pressure in the water pipe 36 satisfies the fourth condition, thereby setting the low water level value.

That is, the fourth condition is a stable value s3 in which a change in water pressure is initially set for a predetermined time t6, for example, 1 second to 5 minutes, preferably 30 seconds, for example, ± 0.01 to ± 0.1 kg / cm. ² , Preferably, the average value is set to the low water level value when it is kept within ± 0.02kg / cm ² . The water pressure below a predetermined level is automatically set to the low water level from the set high water level. This is to set a predetermined height or less from a high water level (for example, 1 m from a high water level ⁾ or to automatically reset a water pressure of a high water level to a low water level below a predetermined water pressure (10 kg / cm ² from a high water level value ⁾ . That is, the low water level, which is the point where the raw water is not completely discharged from the water tank 300, is reset from the high water level by resetting from the high water level.

In the ninth step (S20) and (S21), it is determined whether the water pressure sensed by the pressure sensing means 34 of the water supply pipe is the set low water level value after a predetermined time that the raw water of the water tank is consumed after the low water level value is set. This is to determine whether the raw water of the water tank has reached the low water level due to the consumption of raw water after the low water level is set in step 8 (S19). At this time, the method for detecting the set low water level is to turn on normally during the set time t7 even when a value that satisfies the low water level value is less than the set "0" value for a predetermined time as shown in FIG. 10. This is further applied when the roof is located in a relatively high area from the roof or above ground, and a timer may be added according to the function setting.

In addition, in the tenth step (S22) and (S23), it is determined whether the change in the water pressure meets the fifth condition in the case of the low water level value, and restarts the pumping means to retake the raw water. The fifth condition is a stable value s4 initially set for a predetermined time t7, for example, 1 second to 5 minutes, preferably 30 seconds, for example, -0.01 to -0.1 kg / cm ² , preferably If less than -0.03kg / cm ² is maintained.

On the other hand, Figure 11 is a configuration diagram showing a case of a pressurized field, Figure 12 is a graph showing the change in the water pressure in the case of a pressurized field.

In the case of a pressurized field, the driving is almost similar to that of the well, but unlike the case of the well, since the raw water is supplied with almost the same pressure, the pumping means drives the initial value after the initial value is set. Will be. In the case of such a pressurized field, the change in the water pressure will be increased under the second condition.

In the case of such a pressurized field, it is similar to the water level control method of the intake well, and the adjustment method is the first step of setting various initial values regarding the water pressure of the raw water stored in the water tank after installing the water level automatic control system of the water tank. ; A second step of driving the pumping means under the control of the controller to take the raw water from the pressure field; A third step of determining whether a change in water pressure meets a set first condition from an initial value set while the raw water taken from the pumping means is supplied to the water tank through a water pipe; A fourth step of resetting the average water pressure satisfied when the first condition is satisfied to an initial value; A fifth step of detecting a change in water pressure after the initial value is reset and determining whether a second condition is satisfied from the set initial value; A sixth step of resetting to a high water level value when the second condition is satisfied and determining whether the change in water pressure satisfies the third condition; A seventh step of stopping the driving of the pumping means when the third condition is satisfied; An eighth step of determining whether a change in water pressure in the water pipe satisfies a fourth condition after the driving of the pumping means is stopped, and setting a low water level value; A ninth step of determining whether the water pressure of the water pipe is set to a low water level during a predetermined time period during which the raw water of the water tank is consumed after the low water level is set; In the case of the low water level value, a tenth step of determining whether the change in the water pressure satisfies the fifth condition and restarting the pumping means to retake the raw water is satisfied.

In addition, the method for adjusting the water level of the pressure field is preferably applied when the region is relatively higher than the pressure field, so that the pressure rises by the installation position of the water tank after the first condition is satisfied and the initial value is reset. do. This is the hydraulic pressure to push up the raw water by the difference in altitude from the pressure station to the water tank.

Further, the third condition in the sixth step stops the driving of the pumping means when a predetermined water pressure is satisfied for a predetermined time for a predetermined time, and the method is performed when a plurality of water tanks are connected from one pressurized field. Applicable to

As such, the present invention can be applied when the water level automation method by the system is connected to a plurality of water tanks from one water well and pumping means, the roof of the building or water intake information when the area is relatively high, In addition, the system allows to turn off the driving of the pumping means and to generate an alarm when the predetermined pressure value is maintained for a predetermined time after comparing with the previously set high level value. Alternatively, when the valve is closed or the water pipe is blocked, or when the raw water is used through the bypass pipe, the memory unit 18 is stored because the set high and low water values are stored in a push-pull manner. The capacity of the section 18 does not have to be very large.

On the other hand, in the embodiment of Figure 3 is to extend the end portion (36a) of the water pipe 36 so that the end portion (36a) is submerged in the stored raw water when the raw water stored in the water tank 300 is high water level, It is to make it easy to detect and recognize the change in water pressure without the connection of the ball. At this time, the water pressure sensor 300 for detecting the water pressure of the water tank 300 is connected to the structure.

In addition, Figure 4 is to prevent the large change in the water pressure due to the raw water received from the water supply pipe 36 while the raw water is filled up from the lower end of the water tank 300 when the end portion 36a is extended as shown in FIG. For the purpose, as shown in the detailed view of FIG. 7, the reflector 50 is applied for the purpose of preventing the raw water fed from the water pipe 36 to be repelled or shaken by the raw water filled in the water tank 300, When is filled with more than the reflector 50, there is almost no change in the water pressure due to the shaking of the raw water.

5 is the end portion 36a of the water pipe 36 is connected from the bottom of the water tank 300, which is the raw water is passed through the water pipe 36 is supplied from the bottom of the water tank 300, one water pipe (36) to detect the water supply and pressure of the raw water.

In addition, FIG. 6 is provided with the fitting hole 40 at the end portion 36a of the water pipe 36 connected to the water tank 300, to minimize the change in the water pressure shaking when the high water level is set. Preferably, the high water level value is set without the configuration of the floats 40.

The buoy 40 is supported by a plurality of supports (41, 41a) to move up and down along the guide hole (44, 44a) of the guide line (42, 42a) of the end portion 36a, the low water level or raw water In the state which does not touch 40, the stopper 43 and 43a hang by a guide line by self weight. This is to allow the raw water to be delivered from the water pipe 36 to transmit the increase in the water pressure due to the rise of the float 40, the size of the float 40 is the water supply of the raw water to the end portion (36a) of the water pipe (36) It is to play a role in restraining a little. Therefore, it is desirable to minimize the buckle provided at the end of the water pipe.
