Description

Wireless Automation Water Level Control System {Wireless Automation Water Level Control System}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless automatic water level control system. More particularly, the present invention relates to a constant water, leachate, or wastewater including groundwater (hereinafter, abbreviated as raw water). When the distance from the existing point to the desired storage means through the water pipe is far (10s to several kilometers), the pressure sensing means mounted on one side of the water pipe detects the water pressure and automatically stores the amount of raw water. By determining and controlling, the present invention relates to a wireless automatic level control system that enables efficient level adjustment.

Conventionally, a water level control device installed in a predetermined area to store raw water as a storage means pumps raw water from a predetermined reservoir, reservoir or basement by a pumping means, and supplies it through a water pipe to a storage means installed at a predetermined distance, and stores it. The means detects the amount or level of raw water stored in the sensing means and transfers it to the controller through the 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, when the controller fails to transmit a normal control signal to the pumping means, there is a problem that raw water stored in the storage means overflows. 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, by eliminating the wiring connected to the wire and by installing a pressure sensing means for sensing the water pressure formed in the water pipe at the end of the water pipe to automatically adjust the amount or level of raw water stored in the storage means, It was possible to solve all the problems caused by the wiring and to adjust the water level more accurately.

Referring to the configuration of FIG. 1, the wireless automatic water level control device is equipped with a pumping means 3 for pumping raw water into a water extraction well 2 excavated to a predetermined depth, and the pumping means 3 has a predetermined diameter. The water supply pipe 5 is connected, the intake well 2 has one or more electrode rods 4 having a predetermined length, and the pressure for detecting the water pressure of the raw water supplied from the water supply pipe 5 inside the water supply pipe 5 The sensing means 6 is configured, and the storage means 9 for storing raw water of a predetermined capacity is installed at the end of the water pipe 5, and the controller 1 for controlling the pumping means 3 is pressure sensing. The signal sensed from the means 6 is judged to turn on or off the power applied to the pumping means 3 via the power supply line 7.

One or more electrode 4 is installed, and detects the amount or level of fresh water contained in the water extraction well 2 and outputs it to the controller 1 through the signal line 8, the electrode 4 is detected raw water Since the resistance value changes according to the position of, it is possible to determine the water level according to the output current value. In other words, the installation of the electrode 4 is driven by the pumping means (3) is driven by the power applied from the controller 1 through the power supply line (7) while discharging the raw water to the water pipe (5), the water level is reduced as the amount of raw water is reduced When lowered, the pumping means 3 may pump only raw water and not discharge it. Therefore, the controller 1 determines the signal received from the electrode 4 and cuts off the power applied to the pumping means 3 to prevent the loss of the pumping means 3.

On the other hand, if the raw water is filled in the intake well 2 after the pumping means 3 is stopped, the electrode 4 detects the water level, and the detected water level is determined by the controller 1 and the pumping means ( Supply power to 3) and restart it so that raw water can be pumped.

As described above, in the case of the conventional wireless automatic water level control device, the controller determines the level of the water intake well detected by the electrode to control the pumping means, and the controller controls the water level (or quantity) stored in the storage means from the pressure sensing means in the water pipe. Although it is possible to control the driving of the pumping means by judging the detection signal, the pumping means and the electrode mounted in the intake well are installed and embedded at a predetermined depth from the ground, so the level of raw water cannot be detected accurately due to the loss of the electrode. If the controller fails to detect the water level due to the disconnection or short circuit of the buried signal line even if it is not detected or detected, the controller cannot control the pumping means, which may cause deterioration or loss of the pumping means. I have no choice but to do this. Am, there was a problem that it takes a lot for the replacement.

As such, if the amount of raw water in the well is not accurately detected by the electrode, the pumping means cannot be controlled, resulting in inconvenience in use.

In addition, since the controller senses the input of a simple electrical signal and controls the pumping means by driving a counter or an electronic switch, various control functions cannot be secured, so that more precise control is difficult.

The present invention has been made to solve the above problems, in accordance with the pressure of the raw water pumped from the pumping means by mounting a pressure sensing means in the water pipe instead of installing an electrode to detect the amount or level of raw water in the intake well It is an object of the present invention to provide a wireless automatic level control system for controlling the driving of the pumping means by sensing the amount or level of raw water in the water well.

In addition, the present invention is one or more pressure-sensing means is built in the water pipe or integrally formed in the water pipe, when the raw water of the water well is pumped by the pumping means for a predetermined time when the amount of raw water is depleted to a certain level or less And, in a non-limiting state in which the amount of raw water is not depleted even after pumping for a predetermined time, respectively, it detects the water pressure or quantity flowing out and inflow through the water pipe and outputs the detected signal or judges the detection signal of the pressure sensing means. Another object is to control the driving speed of the pumping means according to the time or the magnitude of the pressure.

In addition, in the present invention, by adopting a control unit to the controller to give various and improved functions, and to configure a display window that can visually display the operating state to display the water level or quantity, the display of the setting state, the display of the operating state or timer It is easy to set for display, and it turns off when the water pressure of the raw water stored in the storage means rises above the set pressure after the driving of the pumping means, and when the water pressure decreases below the set pressure due to the use of the raw water, the pumping means is restarted. Another object is to be able to easily control so that a certain amount of raw water is always stored in the storage means.

In addition, in the present invention, when the raw water in the intake well is not limited, the pumping means determines the amount of pressure transmitted to the pressure sensing means in accordance with the level of raw water at the time of intake of the raw water, and simultaneously controls the driving of the pumping means. Another object is to prevent the pumping means from being driven and deteriorated and lost by controlling the driving of the pumping means by measuring the amount of change in the current transmitted to the pumping means through the controller.

The first embodiment of FIG. 4 is a case in which the water supply pipe 36 is provided with a pressure sensing means 34, that is, one pressure sensing means, and a condition in which the raw water can be taken indefinitely from the water well 24. The water pressure detected by the pressure detecting means 34 is as shown in the graph of FIG. 5.

In the case where such pressure sensing means 34 is mounted, the raw water taken from the water intake well 24 is limited (when the water can be continuously supplied to a predetermined amount of water taken into the storage means). When pumped to the storage means 300 detects the water pressure is formed in the water pipe 36 is converted into an electrical signal and input to the control unit 16, the control unit 16 increases the amount of change in the input water pressure is already set time If it detects more than the set pressure p3 during t1, the control signal is output and the electronic switch 17 is driven to cut off the power applied to the pumping means 22, and the signal related to the input water pressure is set to the set pressure p1.

Therefore, since the raw water is not withdrawn from the pumping means 22, the pressure sensing means 34 detects only the water pressure of the storage means 300, and the water pressure at this time will be a water pressure ps smaller than the high pressure p3. will be. Thereafter, the raw water stored in the storage means 300 is consumed, and when the amount of raw water consumed reaches the set low water level p1, the pressure sensing means 34 of the water supply pipe 36 is driven to the pumping means 22. Power will be applied.

Next, the second embodiment of FIG. 6 is a case in which the water supply pipe 36 is provided with a pressure sensing means 34, that is, one pressure sensing means, and is a condition capable of withdrawing finite water from the intake well 24. If it is. The water pressure detected by the pressure detecting means 34 is as shown in the graph of FIG.

When the pressure sensing means 34 is installed, the water pressure of the raw water pumped through the water pipe 36 and the water pressure of the raw water stored in the storage means 300 are detected when the raw water withdrawn from the intake well 24 is limited. After converting into an electrical signal and inputting to the control unit 16, the control unit 16 is the number of times the instantaneous change is set for a time (t2, t3, t4) the signal relating to the input water pressure is already set (for example, 5 times) or more, and outputs a control signal to drive the electronic switch 17 to cut off the power applied to the pumping means 22, the electronic switch 17 after a predetermined time (t5, t6, t7) set Re-pumping is performed by supplying power to the pumping means 22 to drive the pump. When a signal related to the input water pressure is detected to be higher than the set water pressure p3 for the set time t8, the pump outputs a control signal. Authorized as 22 It is to drive a magnetic switch (17) so that the power is cut off.

In the graph of FIG. 7, the water pressure sensed by the pressure detecting means 34 is obtained from the water intake well 24 at the initial stage of installing the water well 24, the controller 100, the water pipe 36, and the storage means 300. When the water is taken in, the water pressure starts in the state of p0, and after the water is taken in, the pumping means 22 is automatically driven in the case of the low water level p1. The initial pumping pressure of the pumping means 22 is determined at p2, and it is preferable that the water pipe 36 can sufficiently withstand the hydraulic pressure p2 initially pumped. In addition, the water pressure of the pumped raw water gradually increases in the water pipe 36, and when the raw water that can be withdrawn from the water inlet 24 is limited, the water level of the water inlet is changed with a predetermined number of times for a predetermined time (t2, t3, t4). When generated, the power applied to the pumping means 22 is cut off so that the water can be stopped. At this time, in the blocked state, the pressure sensing means 34 senses the pressure of the raw water stored from the storage means 300, and the pumping means 22 for the time t5, t6, t7 set by the control of the controller 16. The water is stopped and the water is taken again, so that the raw water can be continuously stored in the storage means 300. In addition, if the predetermined pressure continuously rises for a predetermined time t8 after the high water level p3 set by the pressure sensing means 34 during intake, the pumping means (controlled by the control unit 16 of the controller 100) The power applied to 22) is cut off. Therefore, since the raw water is not withdrawn from the pumping means 22, the pressure sensing means 34 detects only the water pressure of the storage means 300, and the water pressure at this time will be a water pressure ps smaller than the high pressure p3. will be. Thereafter, the raw water stored in the storage means 300 is consumed, and when the amount of raw water consumed reaches the set low water level p1, the pressure sensing means 34 of the water supply pipe 36 is driven to the pumping means 22. Water is supplied by applying power.

Next, the third embodiment of FIG. 8 is a case in which the water supply pipe 36 is provided with one or more pressure sensing means, that is, the first pressure sensing means 34 and the second pressure sensing means 35. A check valve 33 is provided between the means 34 and the second pressure sensing means 35, and the first pressure sensing means 34 senses the water pressure of the raw water withdrawn from the well, and the second pressure sensing means. 35 is to detect the water pressure formed in the storage means 300 and the water pipe 36 to output a signal relating to the water pressure detected by the main controller 100, respectively.

It is equipped with a second pressure detecting means 35 in the water pipe 36, the first pressure detecting means 34 detects only the water pressure of the raw water taken out from the intake well 24 and outputs the detected signal to the controller 16 And, the second pressure detecting means 35 is configured to detect only the water pressure formed from the water pipe 36 and the storage means 300 to output the detected signal to the controller 16.

In such a case, a graph showing the relationship between the pressure P1 and the time t of the first pressure sensing means 34 of FIG. 9A, the pressure P2 of the second pressure sensing means 35 of FIG. 9B, and Refer to the graph showing the relationship with time t.

That is, the first pressure detecting means 34 detects only the set water pressure p2 of the raw water being pumped when the raw water withdrawn from the water extraction well 24 is indefinite, and the detected pressure is set for the set time t9. p4) or less, or when the detected signal is greater than or equal to the set water pressure p5 for the set time t9, the controller 16 determines that the abnormal pressure rise or the abnormal pressure drop outputs a control signal and is applied to the pumping means 22. The electronic switch 17 is driven to cut off power.

In addition, in FIG. 9B, the second pressure detecting means 35 detects only the water pressure formed in the storage means 300 and the water pipe 36 irrespective of the water pressure of the raw water withdrawn from the intake well 24. 2 If the signal detected by the pressure detecting means 35 for a predetermined time t10 is greater than the set water pressure p3, the electronic switch 17 outputs a control signal so that the power applied to the pumping means 22 is cut off. When the signal related to the input water pressure is detected below the set water pressure (p1) to output a control signal to drive the electronic switch 17 so that power is applied to the pumping means (22). If the raw water is not withdrawn from the pumping means 22, the second pressure detecting means 35 detects only the water pressure of the storage means 300, and the water pressure at this time is less than the high pressure p3. After that, the raw water is consumed from the storage means 300.

Next, the fourth embodiment of FIG. 10 is a case in which the water supply pipe 36 includes one or more pressure sensing means, that is, the first pressure sensing means 34 and the second pressure sensing means 35. In this case, the amount of raw water withdrawn from the water extraction well 24 is limited.

In this case, a graph showing the relationship between the pressure P1 and the time t of the first pressure sensing means 34 of FIG. 11A, the pressure P2 of the second pressure sensing means 35 of FIG. 11B, and Refer to the graph showing the relationship with time t.

The first pressure detecting means 34 detects the raw water pumped from the pumping means 22 of the water intake well 24 to detect the water pressure continuously pumped after the initial pumping pressure, and then for a predetermined time (t11, t12, t13). If the water level is changed by the predetermined number of times from the water well 24, the controller 16 determines that the raw water in the water well 24 is not normally pumped by the detection signal of the first pressure sensing means 34, and pumping means 22. Cut off the power supply. After the power applied to the pumping means 22 is cut off, it is delayed for a predetermined time (t14, t15, t16), which will be the time that the raw water in the water well 24 is filled to the normal water level. If an abnormal pressure rise or an abnormal pressure drop occurs for a predetermined time t17 during the normal pumping from the water intake well 24, the controller 16 determines this and cuts off the power applied to the pumping means 22. The abnormal pressure rise or abnormal pressure drop is for the protection of the pumping means 22 and the water supply pipe 36 when the normal water is not made due to the failure of the pumping means 22 or the blockage of the water supply pipe 36.

In addition, the second pressure detecting means 35 detects the water pressure of the raw water taken out from the pumping means 22 and supplied to the storage means 300 through the water supply pipe 36, and simultaneously with the driving of the pumping means 22. After the initial pumping pressure p2, the pressure gradually increases, and then the second pressure sensing means 35 occurs when the controller 16 stops driving the pumping means 22 according to the detected signal of the first pressure sensing means 34. ) Detects only the water pressure applied from the water pipe 36 and the storage means 300 during the time t18, t19, t20 is not pumped and outputs to the controller 16. Furthermore, when the second pressure detecting means 35 senses the water pressure formed in the water pipe 36 and detects the pressure p8 or more for a predetermined time t21, the controller 16 controls the electronic switch 17. The control signal is output to cut off the power applied to the pumping means 22 to stop the driving of the pumping means 22. This is to determine that the storage of raw water is completed in the storage means 300, and when the intake of raw water is finished, the second pressure sensing means 35 is not collected from the pumping means 22, so the storage means 300 Only the pure water pressure is detected, and the water pressure is a water pressure (ps) smaller than the high water pressure (p8), after which the raw water is consumed from the storage means (300). Thereafter, after the consumption of the stored raw water is made, when the water pressure detected by the water supply pipe 36 reaches the set low water level p1, the controller 16 drives the electronic switch 17 to supply power to the pumping means 22, thereby pumping means. (22) is operated to intake water.

12 is another embodiment, by installing one pressure sensing means in the water pipe 36 to detect the water level of the storage means 300 by the detection of the water pressure in the water pipe 36, and to detect the water level in the water well 24 It is equipped with a pneumatic pipe 37 and a pneumatic sensor 35 (second pressure sensing means) to detect the water level change in the water intake well 24. At this time, the water intake well 24 may take in a finite number of raw water, and when the raw water is exhausted during the pumping of the raw water, the driving of the pumping means 22 is stopped, and when the raw water returns to a predetermined level, the pumping means 22 is It is driven again to take in the raw water.

In this case, by detecting the water level of the water intake well 24 using the pneumatic pipe 37 and the pneumatic sensor 35, it is possible to prevent the pumping means 22 from being driven in an unauthorized manner.

That is, when the raw water of the water intake well 24 is at the position of the high water level (H), the pumping means 22 ingests and supplies the raw water through the water supply pipe 36 without any difficulty, but the raw water of the water intake well 24 is depleted and is low. (L), the pumping means 22 is unable to normal intake, which means that when the air pressure formed in the pneumatic pipe 37 is the high water level of the raw water of the water well 24, the air in the pneumatic pipe 37 by the atmospheric pressure Since the pressure is applied to the pneumatic sensor 35 is increased, and this value is input to the main controller 100 via the driver controller 111, the main controller 100 is compared with the set value and judged after the pumping means ( 22) It continuously supplies the driving power applied. However, as the water level of the raw water in the intake well 24 decreases, the air pressure of the pneumatic pipe 37 decreases, and thus the detected value of the pneumatic sensor 35 is input to the main controller 100 via the driver controller 110. After comparing and calculating the set value and the input value, the main controller 100 stops the intake by cutting off the driving power applied to the pumping means 22 when it is determined that the water level is at the low water level (L).

Therefore, the pumping means 22 is normally driven only when there is raw water above the low water level L in the intake well 24, and the driving power applied when the pumping means 22 withdraws the normal raw water is constant, When the water level is lowered in 24) and the amount of raw water taken by the pumping means 22 becomes smaller, the size of the driving power applied to the pumping means 22 also becomes smaller.

Accordingly, even if the pneumatic sensor, that is, the second pressure detecting means 35 does not sense the amount of raw water in the water intake well 24, the main controller 100 determines the size of the driving power applied to the pumping means 22 to determine the intake well ( It is possible to determine whether the enemy of 24) is exhausted.

FIG. 13A illustrates that the control unit 16 of the main controller 100 controls the driving of the pumping means based on the initial set value without first resetting the water level of the storage means 300 to the first setting in the present invention. First, after the raw water is collected and supplied to the storage means 300 and the raw water of the water level desired by the user is filled in the storage means 300, the driving of the pumping means 22 is stopped (a). After the driving of the pumping means 22 is stopped, the user determines a position determined as the high water level p3 as an initial set value. After the initial set value is determined, the raw water is supplied through the water supply pipe 330, and the raw water in the storage means 300 is driven by the pumping means 22 when the raw water in the storage means 300 is supplied to the desired low water level p1. Set to lose. At this time, to set the low water level (p1) that is the pumping start value (c). When the pumping means 22 is pumped again, when the raw water is filled up to the position set at the initial high water level p3 in the storage means 300, the pumping means 22 is stopped at the off value d. In other words, the initial set value (b), the pumping start value (c) and the off value (c) is set to the value detected by the pressure sensing means (34).

In addition, FIG. 13B illustrates an example of a pressurized field, in which an ripple component is generated at an off value (e), in which raw water of the pressurized field is not normally supplied, and FIG. 13C illustrates an example of a well. When the value of the number of circuits changes (f) for a given period of time, i.e., when the momentary value fails to recover as much as the given value, the water level is restored when the water level of the water well is below the standard level, and the pumping means is excessive. So that it can be pumped back normally.

Figure 14 shows a structure for more accurately detecting the water level of the raw water stored in the storage means 300 through the water pipe 36, the pressure sensing pipe connected to the T-shaped pipe 320 coupled to the bottom of the water pipe 36 Connect the fallopian tube 322 to one end of the 321 to sense the atmospheric pressure, that is, the water pressure of the raw water stored in the storage means 300 to deliver to the pressure sensing means 34 through the water pipe 36. The fallopian tube 322 of the storage means 300 is preferably mounted in a position opposite to the water supply pipe 330 or less influence each other. Accordingly, in the case of FIG. 15, the pressure sensing tube 321 and the fallopian tube 322 are configured at a position as far as possible from the portion where the water supply pipe 330 is located.

Figure 16 shows another embodiment for detecting the water level of the storage means 300, by inserting a separate inner tube 325 in the water pipe 36 to supply the raw water to the water pipe 36, the inner pipe 325 In order to detect the water pressure of the storage means 300 to determine a more accurate water level.

Furthermore, FIG. 17 does not apply the mouth of the opening and closing means 310 installed at the end of the water pipe 36 in the form of a sphere, and applies a cone to minimize the fluctuation or movement of the raw water stored in the storage means 300. It is to detect more accurately.

18 is an extension pipe 324 formed with a plurality of hydraulic holes 323 in the fallopian tube 322 connected to the hydraulic pressure sensing pipe 321, the raw water to be supplied to the water supply pipe 330 or the change in water pressure by the shaking of the raw water It is possible to detect the exact water pressure from the change of.

19 illustrates a flow related to the driving of the pumping means 22 in the automatic mode through the main controller 100 of the present invention. When power is supplied to the main controller 100 in step S10, the mode The lamp of the setting key 51 is turned on and is executed in the automatic mode. During operation in the manual mode, the mode setting key 51 is pressed and the lamp of the mode setting key 51 is turned on to operate in the automatic mode.

If the automatic mode in step (S11), the lamp of the motor setting key 52 is turned on, the pumping means 22 is connected to the contact A and the driving state. In step S12, the standby state is maintained for a start delay time, and in step S13, when the pressure is greater than a predetermined time, for example, a pressure of 16 seconds before at a 1 second interval, it is recognized as a pressure increase.

In step S14, it is determined whether it is continuously generated for the end delay time, and when it is continuously generated, the pumping means 22 is stopped while the lamp of the motor setting key 52 is turned off by recognizing the high water level in step S16. However, if it is not continuously generated during the end delay time in step S15, the pumping means 22 is maintained in the driving state.

In step S17, the pumping means 22 is stopped and maintains the standby state for a pressure stabilization delay time (e.g., 2 minutes, self time). In step S18, the lamp is turned on until the water level display means 46 is 'Full' after the standby state passes. At this time, the displayed pressure value and the set value (low water level) of the level setting key 53 are calculated. That is, it is calculated by the set value (cm) of the low water level (cm) = (pressure value in the full state x 1000) (cm)-level setting key.

If the current water level is greater than the low water level in step S19, the current state is maintained. Otherwise, if the current water level is less than or equal to the low water level, the pumping means 22 is driven again.

On the other hand, when the main controller is in the automatic mode, when the groundwater, that is, the raw water in the intake well is depleted, referring to the flowchart of FIG. 20, when the power is supplied to the main controller 100 in step S20, the mode is The lamp of the setting key 51 is turned on and is executed in the automatic mode. During operation in the manual mode, the mode setting key 51 is pressed and the lamp of the mode setting key 51 is turned on to operate in the automatic mode.

If the automatic mode in step (S21), the lamp of the motor setting key 52 is turned on, the pumping means 22 is connected to the contact A and the driving state. In step S22, the air condition is maintained for a start delay time, and in step S23, the amount of pressure change is checked, that is, the test is performed at a low pressure to a high pressure, and at a high pressure to a low pressure. One count is decremented when greater than or equal to / cm2. If the phenomenon continues, for example, more than 60 times, the pumping means 22 stops, and when the change amount is less than 0.1 kg / cm2, it is regarded as the normal pressure and is increased by one count every time the count is maintained for 5 seconds or more. .

Therefore, if it is not generated more than the number of times set continuously in step S24, the pumping means 22 is kept on continuously, and in step S25, the pumping means 22 is stopped for a set reset time after stopping. After the standby state, restarting takes place.

In addition, in the manual mode in FIG. 21, first, when power is supplied to the main controller 100 in step S30, the lamp of the mode setting key 51 is turned on and is executed in the automatic mode. In the manual mode, the mode setting key 51 is pressed and the lamp of the mode setting key 51 goes out to operate in the manual mode. This is used when the user wants to operate the pumping means 22 arbitrarily. In step S31, it is determined whether the driving switch of the pumping means 22 is on, so that the contact A is connected and the contact B is not connected. Step S32 which is a state, and step S33 which is a state where the B contact is connected rather than the A contact are connected.

22 is a flowchart illustrating an operation state of the main controller of the present invention. When the detected value of the pressure sensing means 34 is output in step S40, the amplification unit amplifies to a predetermined size through the amplifying means in step S41. In step S42, the voltage is converted into a frequency through a voltage / frequency converter. The converted frequency is input to the control unit in operation S43 and then outputs a control signal. At this time, the display is displayed through the display window in step S44, and the pumping means 22 is controlled by the control of the contact point in step S45.

The first and second pressure sensing means 34 and 35 sense the level of the storage means 300 and the level of the water intake well 24 using one pressure sensing means to provide data to the controller 16. The controller 16 drives the electronic switch 17 to apply power to the pumping means 22, so that the pumping means 22 is operated to take water.

As shown in FIG. 23, the sensing means may be embedded in a predetermined space provided in the inner pipe 39 of the water pipe 36 or may be integrally mounted with the water pipe 36. The pressure sensing means 34 can be mounted to the pressure sensing means 34, and the pressure sensing means 34 is mounted within a range of preventing the raw water from flowing into the water supply pipe 36. 34a is preferably mounted on the same surface as the inner diameter of the water pipe 36. That is, in FIG. 24, the water supply pipe 36 includes an inner pipe 39 and an outer pipe 38, and the pressure sensing means 34 is built in the inner pipe 39. The signal sensed by the pressure sensing means 34 is input to the controller 16 of the main controller 100 along the inner pipe 39 of the water supply pipe 36.

The form in which the pressure sensing means 34 is mounted depends on the cross section secured to the water pipe 36, which is preferably mounted as shown in Figs. 25A to 25D. That is, in FIG. 25A, the thickness of one end of the end face of the water pipe 36 on which the pressure sensing means 34 is mounted is formed thick, FIG. 25B shows the thick end of the inner diameter at the same outer diameter, and FIG. It is formed convexly, FIG. 25D shows that the pressure sensing means 34 is mounted on the outside of the water supply pipe 36, and only the sensing portion 34a is mounted on the surface of the inner pipe 39.

As illustrated in FIG. 26, the first pressure sensing means 34 (or the second pressure sensing means 35 when the second pressure sensing means 35 is included) is pumped into a plurality of storage means 300. When the means 22 and the water pipe 36 are connected, each water pipe 36 is mounted and the amount or level of raw water is displayed on the display window 40 of the control panel 12 under the control of the controller 16, respectively. The value may be stored in the memory unit 18.

In addition, the first pressure sensing means 34 or the second pressure sensing means 35, as shown in Figure 27, when a plurality of storage means 300 is connected from one pumping means 22 and the water supply pipe 36 The water supply pipe 36 is mounted on each water pipe 36 so that the amount or level of raw water can be displayed on the display window 40 of the control panel unit 12 under the control of the control unit 16, and the value can be stored in the memory unit 18. It is.

The water pipes 36 of FIGS. 26 and 27 are equipped with first or second pressure sensing means 34 and 35, respectively, and detect the amount of raw water supplied through the water pipes 36.

The present invention configured as described above allows the user at the control panel unit 12 of the main controller 100 when the pumping means 22 is separated by a predetermined distance from the water extraction well 24 and the storage means 300. According to the setting of the pumping means 22 can be controlled.

The control of the pumping means 22 is when the amount or level of raw water in the intake well 24 is less than the set value and when the amount or level of raw water stored in the storage means 300 is above or below the set level.

That is, the user can operate the pumping means 22 in the manual mode and the automatic mode by the operation of the control panel unit 12, and in the manual mode, by manipulating the mode setting key 51 of the state unit 50 forcibly. The pumping means 22 can be turned on or off. In this case, the pumping means 22 may be set to be automatically operated by the data set by the mode setting key 51 or the pumping means 22 may be driven by the detection of the pressure sensing means 34. Therefore, when the mode setting key 51 is set to the manual mode, the motor setting key 52 can be operated to directly drive or stop the pumping means 22.

In the automatic mode, when the user uses the stored value set by the user, if the corresponding key of the selection unit 60 is used in the automatic mode, the previous process is ignored and all processes are performed in the automatic mode. When the second pressure sensing means 35 is turned on at the high water level during the cycle time, the process from the automatic mode to the cycle time is repeated several times (for example, 15 times), and the automatic mode is doubled when it is continuously turned on at the high water level. When the second pressure sensing means 35 is continuously turned on at the high water level even after the set process is repeated several times until the cycle time again, all operations of the main controller 100 are turned off until there is an external input. However, when the second pressure sensing means 35 is turned off at the high water level during the cycle time, the pumping means 22 operates to perform the next process, and when the pumping means 22 is in the on state at the high water level, the pumping is performed. The means 22 is off to perform the next process.

In addition, when the setting of the main controller 100 is the manual mode, the user does not use the set value and the stored value, and supplies or cuts off AC power (AC220V, 60Hz) using the motor setting key 52 to pump the means 22. ) Forcibly on or off.

In addition, the main controller 100 increases the current and voltage applied to the pumping means 22 when the raw water is above a predetermined level according to the driving of the pumping means 22 when the raw water in the intake well 24 is not limited. When the water level is below a predetermined level, since the current and voltage applied to the pumping means 22 are reduced, it may be determined to control the driving of the pumping means 22. That is, when the main controller 100 drives the pumping means 22 so that the pumping means 22 withdraws the raw water normally, the magnitude of the current and voltage applied to the pumping means 22 is constant, but the pumping means ( 22) If the raw water is not at the normal level while taking the limited raw water, for example, if the raw water supplied through the pumping means 22 is not 100% supplied and mixed with air, the pumping means 22 is supplied to the pumping means 22. Since the magnitude of the applied voltage and current is smaller than the size normally applied, the main controller 100 detects this and stops the driving of the pumping means 22.

On the other hand, Figure 28 is a flow chart related to the operation of the system for adjusting the water level wirelessly, in step (S100) the water well 24, the water pipe 36 and the storage means 300 and the main including the controller 16 After installing the controller 100, the driver controller 110 and one or more pressure sensing means (34, 35) storage step by the driving of the pumping means 22 for the initial withdrawal from the water well 24 in step S101 Save 300 enemies.

In the state in which the raw water is stored in the storage means 300, in step S102, the high and low water levels of the raw water stored in the storage means 300 are set to initial values. That is, referring to the setting value for converting the variable water level according to the sensing value of Table 1 as an example.

division Pressure sensor (pressure (kg · f / cm2)) Inside of storage means (height (m)) Control Water level Set One 4.0 3.0 High water reset 2 3.9 2.9 ↑ · 3 3.8 2.8 ↑ · 4 3.7 2.7 ↑ · 5 3.6 2.6 ↑ · 6 3.5 2.5 ↑ · 7 3.4 2.4 ↑ · : : : : · 16 2.5 1.5 ↓ · 17 2.4 1.4 ↓ · : : : ↓ · 28 1.3 0.3 ↓ · 29 1.2 0.2 Water level 5 times / min 30 1.1 0.1 － 31 1.0 0.0 －

As shown in Table 1, if the user sets the desired high water level to the controller 16 at 3m from the bottom of the storage means 300, and the pressure applied by the water pressure is 4kg / cm2, for example, the pressure is 0.1kg for every 0.1m. Since / cm2, the water level of the storage means 300 may be determined according to the pressure applied. In addition, if the low water level of the storage means 300 is set to 0.2m from the bottom to the controller 16, the pressure detected at 0.2m becomes 1.2kg / cm2, so the controller 16 determines that 1.2kg / cm2 is the low water level. Done. The low water value may be an absolute value or a relative value.

Therefore, the controller 16 may determine the level of raw water stored in the storage means 300 according to the initially set value. In addition, the case of Table 1 is described as an example, but it is possible to set the high and low water level according to the user's request, when the pressure sensing means (34, 35) for precise detection (for example, 0.001 or less) Although it is possible to detect a finer water level, it can be seen that the pressure sensing means 34 and 35 can be easily set even if the detection is not very precise (0.1 or more).

In the state set in the control unit 16 as described above, in step S103, the pressure sensing means 34 and 35 sense the pressure of the storage means 300, and then, in step S104, it is determined whether the detected pressure is the set low water level. . That is, it is determined whether the raw water in the storage means 300 is the low water level set in the control unit 16 as shown in the conversion table of Table 1 while the raw water is consumed in the state of being initially stored at the high water level in the storage means 300.

At this time, when the low water level is detected in step S105, the pumping means 22 is applied by supplying power to the pumping means 22 by driving the electronic switch 17 under the control of the controller 16 of the controller 100. By operating, raw water is taken.

In step S106, the pressure sensing means 34 and 35 continuously detect the pressure of the raw water pumped from the intake well 24, and determine whether the reference pressure set in step S107, that is, the set high water level. If the raw water of the water extraction well 24 is limited, if it is detected below the standard pressure value set in the control unit 16 in step S108, it is determined that the raw water is not supplied from the water well 24 and pumping means 22 Stop the power supply to).

After the pumping means 22 is stopped in step S109, it is determined whether the set time has elapsed. If the time elapses, the pumping is restarted in step S110, and the raw water stored from the storage means 300 is stored in step S111. The pressure generated from the water pipe 36 is continuously detected. If it is determined in step S112 whether the detected pressure is a high water level, and reaches a high water level, in step S113, the driving of the pumping means 22 is stopped to stop the water intake.

At this time, in step S114, the controller 16 continues to detect the pressure change of the storage means after resetting the current water level stored in the storage means 300 to a high water level. In other words, when the high water level initially set becomes the high water level set in the next water intake process, the controller 16 resets the current water level to the high water level so that the high water level may be determined at the next water intake. This may vary depending on the sensing capability of the pressure sensing means (34, 35). In other words, when the pressure sensing means 34 and 35 are precise, the initial high water level can be judged as a high water level, but when the detection capacity is somewhat low, the high water level can be reset to prevent an error due to the detection capability. It is to.

Furthermore, in the present invention, the time when the water pressure formed in the water pipe 36 is constantly stabilized after the high water level value is set, recognizes the high water level value many times per predetermined time (for example, 16 times per second). At this time, the setting and recognition of the high water level can be variably set according to the size of the storage means 300 or the pumping capacity of the pumping means, which can be applied to a general building or a household water tank.

If the raw water of the intake well 24 is not limited, the step (S108) and step (S109) will not go through. In addition, when there is more than one pressure sensing means 34 and 35, it is obvious that the conversion table shown in Table 1 may be applied to the controller 16 according to the sensing capability of the corresponding pressure sensing means 34 and 35.

As described above, the wireless automatic water level control system of the present invention makes it easy to adjust the raw water by setting the pressure of the raw water supplied through the water pipe 36 and setting the timer without the need for a separate wiring for remote control. The present invention is not limited to the various embodiments and ranges described above, but can be easily modified, substituted, and changed by those skilled in the art.

As described above, the present invention controls the driving of the pumping means by determining the amount or level of raw water in the intake well with a pressure sensing means mounted in the water pipe without installing a separate electrode in the intake well, thereby increasing the amount or level of raw water in the intake well. The pumping means is prevented from being driven without reference when the reference value is lower than the standard, and the pressure sensing means detects the amount or level of raw water stored in the storage means and controls the pumping means when the raw water is at high or low water level. The water level can be adjusted wirelessly, and the controller and the control panel are configured in the controller to set the intake of raw water by the automatic mode, the manual mode, or the detection of the pressure sensing means, or to set the intake time by the user's operation. To make the intake of raw water more automated It can extend the life of ping means and control the pumping means wirelessly to significantly reduce the cost of installation and maintenance, can be applied to household, industrial and agricultural use, and improve the weather resistance and durability of water pipes. It is effective.
