Description

Reserve water controlling system for water works

The present invention relates to a water storage control system for waterworks, and more particularly, to more precise wireless data transmission and reception between a motor pump for pumping water into a water source including groundwater and a water intake tank for storing water pumped by a motor pump. The present invention relates to a water supply control system for controlling water level in an intake tank.

In general, rural areas or remote mountain ranges far from urban areas still have insufficient water supply rates. In these areas, groundwater or surface water is pumped up and stored in storage or intake tanks, and then located remotely from the storage or intake tanks. You will use a small water supply to your home.

As such, the water supply facility is provided with a motor pump and a controller for controlling the on / off control of the motor pump in a water supply source, and a water intake tank for storing water while sensing the water level of the pumped water at a distance from the motor pump of the water supply source. A controller for controlling the motor pump is installed in the intake tank when water is completed, and the water drawn from the motor pump is stored in the intake tank through a water supply pipe embedded between the motor pump and the intake tank.

When the water is stored in the water intake tank, when the water reaches the water storage tank below a predetermined water storage standard, the controller of the intake tank sends a signal to the controller of the motor pump to drive the motor pump to pump the water pumped by the motor pump. The water level is stored in the water intake tank through a water supply pipe, and the water level is sensed through a water level sensing means. When the water level reaches a predetermined low water level, the controller of the motor pump is connected to the wired line from the controller of the water intake tank. By sending a control signal to the motor to stop the driving of the motor pump, it is used while storing water in the intake tank.

Conventional water supply facilities to be used in this way is to control the motor pump using a wired line between the motor pump and the water intake tank of the water source.

And the length of the wire line is usually several tens of meters-several kilometers, which is to be buried in the hypothesis or ground in Jeonju.

Therefore, in case of wired lines installed on the electric poles, they are easily affected by the surrounding environment (climate, temperature, etc.), and when they are buried in the ground, they are easily affected by landslides and floods, and are frequently disconnected, shorted or leaked. In addition, due to the frequent failures, there is an uneconomical problem in that the cost of repair and maintenance is high.

Therefore, in order to solve the problem of facility maintenance due to the construction and laying of the wireline, a flow rate detecting means for detecting the flow rate of water supplied to the water supply pipe between the motor pump and the water intake tank of the water source or Pressure sensing means for sensing a pressure state of water; One or more timers or counters and relays may be configured to control the motor pump by the pressure or flow of water supplied from the motor pump to the intake tank, and may also include a radio signal inside the controller provided in the motor pump of the water supply. A wireless receiver for receiving at a common frequency and a wireless transmitter for transmitting a radio signal according to a signal sensed by the water level sensing means to a controller of the intake tank, and receiving a signal transmitted from the radio transmitter at the radio receiver. There was a thing to control the drive of the motor pump.

However, in the former case, the water level of the intake tank can be adjusted while controlling the motor pump without using the wire line between the water pump motor and the intake tank to solve the economic problems due to the construction, laying and maintenance of the wire line. However, in the case of the flow rate or pressure sensing means, since the operation is performed by the action of water directly applied, for example, when the pipe contains a lot of foreign matter in old or pumped water, the foreign matter is flow rate or pressure sensing means normally Not only does it interfere with operation, but it causes a problem that causes frequent failures.

On the other hand, in the latter case, the radio signal (common frequency) transmitted and received is easily affected by the harmonic signal of the surrounding environment, so that the radio signal transmitted from the intake tank is not normally received by the motor pump or is received as an erroneous signal. The motor pump control is not performed normally or does not operate.

In addition, the radio signal transmitted from the intake tank is unilaterally received and operated by the motor pump side, so that the motor pump does not operate on the receiver side when the signal transmitted from the transmitter side is not correctly received on the receiver side. Water can not be stored in the intake tank, or water overflowed in the intake tank has caused a user has to check the abnormality of the motor pump and the intake tank of a remote water source located at a distance from time to time.

Accordingly, an object of the present invention is to provide a two-way transmission and reception wireless data signal using a dedicated frequency between a motor pump of a water supply and a remote intake tank for storing water so that the water level can be controlled while checking the operation state in the intake tank. In order to provide a more reliable reservoir control system without being influenced by the surrounding environment.

Another object of the present invention is to be able to check the abnormal state in a separate receiver at home when the abnormality occurs in the motor pump and the water intake tank of the water source by the natural environment or other causes, so that it can quickly cope with the occurrence of the abnormality, This is to solve the inconvenience caused by the above.

The present invention provides a motor pump for pumping water from a water supply source to realize the above object; A water supply pipe for supplying water pumped from the motor pump; A water intake tank for storing water supplied from the water supply pipe; A pump transmission / reception controller for transmitting a wireless data signal according to whether the motor pump is driven to the intake tank and receiving a wireless data signal from the intake tank to control the pump; Receiving a wireless data signal transmitted from the pump transmission and reception controller, and detects the water level stored in the intake tank, it is configured by the intake tank transmission and reception controller for transmitting a signal according to the detected water level to the motor pump.

The intake tank transmission and reception controller is characterized in that it further comprises a voice synthesis integrated circuit for converting and outputting the abnormal state to the voice data when the abnormality of the motor pump and the water level abnormality of the intake tank.

The intake tank transmission and reception controller is characterized in that it further comprises a separate radio receiver for receiving the transmitted voice data.

Therefore, the present invention provides a more reliable two-way wireless transmission and reception data between remote intake tanks storing water pumped from a motor pump of a water source to operate while accurately recognizing the operating state of the motor pump and the intake tank, Water can not be stored due to the abnormality or damage caused by flooding can be prevented, and the abnormal state of the motor pump and the water intake tank can be easily grasped by voice data at home, thereby promptly responding to the occurrence of the abnormality. Measures can be taken to prevent damage caused by long-term neglect of the abnormal condition and to reduce the life of the device, thereby prolonging the life of the system.

Allow the user to know the abnormal state of the tank 120.

According to the present invention constituted as described above, the motor pump 100 and the pump transmission / reception controller 140 are installed to pump groundwater in a water supply area, and the motor is disposed in a water intake tank 120 remotely installed as the motor pump 100. Intake tank transmission and reception controller 150 is installed so that the wireless data signal transmitted from the pump transmission and reception controller 140 can be easily received.

In the state where the motor pump transmission and reception controller 140 and the intake tank transmission and reception controller 150 are installed in each of the motor pump 100 and the intake tank 120, water is supplied from the motor pump 100 to the intake tank 120. In the description of the water storage process, the central processing unit 153 of the intake tank transmission and reception controller 150 displays the state of the water level from the water level sensor 130 installed in the intake tank 120 through the water level detection input units 151 and 152. Will be entered.

In this case, when the water level input signal is input from the water level detection unit 151 among the water level detection units 151 and 152, the central processing unit 153 determines that the water level is low in the water intake tank 120. In order to store at 120, the motor pump driving data and the identification code designated through the unique identification code unit 155 are output to the wireless transmission / reception module 154 through the data terminal DATA.

The wireless transmit / receive module 154 loads the input motor pump driving data and the designated identification code on a dedicated frequency (447 MHz band) and transmits them to the pump transmit / receive controller 140 located at a remote water source region through an antenna.

The motor pump transmission / reception controller 140 receives wireless data transmitted from the water intake tank transmission / reception controller 150 through a wireless transmission / reception module 144 and inputs the data to the central processing unit 143. In step 143, the input data signal is controlled by the predetermined program to determine whether the input data signal is identical to the identification code specified by the unique identification code unit 145, thereby controlling the input wireless data.

In this case, when the identification codes input from the CPU 143 do not coincide with each other, the CPU 143 does not perform a control operation.

On the other hand, when the designated identification codes match with each other, the CPU 143 controls the input wireless data, and outputs the controlled data to the transistor Q1 of the pump driver 141 to output the transistor Q1. By turning on, the relay RY operates to drive the motor pump 100 so that the motor pump 100 pumps water to pump water from the motor pump 100 to the intake tank 120. Water is stored through the water supply pipe (110).

At this time, in the central processing unit 143 of the motor pump transmission and reception controller 140, the driving signal of the motor pump 100 through the input resistance (R2), bias resistor (R3), zener diode (ZD) of the pump signal input unit 142. Receives and transmits the pump driving data to the wireless transmission and reception module 156 of the intake tank transmission and reception controller 150 through the wireless transmission and reception module 146 together with the identification code specified from the unique identification code unit 145. .

The wireless transmission / reception module 156 of the intake tank transmission / reception controller 150 receives the designated identification code and the pump driving data and inputs them to the central processing unit 153, and the central processing unit 153 inputs the designated identification. It is determined whether the motor pump 100 is operating normally while judging whether the code and the pump driving data match each other with the identification code designated by the unique identification code unit 155 by a predetermined program.

At this time, if it is determined that the motor pump 100 is operating normally, the CPU 153 no longer transmits a signal for driving the motor, and determines whether a water level signal is input from the water level detection input unit 152. As you proceed to the reservoir.

However, when the motor pump 100 is not driven due to other factors in the motor pump transmission / reception controller 140, there is no signal input to the pump signal input unit 142, and therefore, no operation is performed in the CPU 143. Will not.

At this time, although the intake tank transmit / receive controller 150 has no signal transmitted from the wireless transmit / receive module 144 of the motor pump transmit / receive controller 140, even though the intake tank transmit / receive controller 150 transmits the The wireless data signal is transmitted a predetermined number of times until a signal for driving the motor pump 100 is received from the motor pump transmission / reception controller 140.

If the signal for driving the motor is not received from the motor pump transmission / reception controller 140 even though the wireless data signal is transmitted a predetermined number of times, an error is displayed on the display unit 157 and the water intake tank is transmitted and received. In the controller 150, as shown in FIG. 4, the voice message indicates that an abnormality has occurred in the motor pump 100 or the motor pump transmission / reception controller 140 by a predetermined program through the voice synthesis integrated circuit 160. The radio transceiver module 156 transmits to a separate radio receiver 170.

Therefore, a person or household having the wireless receiver 170 will listen to the voice message received from the wireless receiver 170 and go to the place where the abnormality occurs and take action promptly.

Meanwhile, in the state in which the motor pump 100 operates normally and is stored in the water intake tank 120, the water level sensor 130 is provided by the water level sensor 130 in the central processing unit 153 of the water intake tank transceiver controller 140. The water level being stored in the water intake tank 120 through 152 is stored while detecting whether the high water level has been reached.

Subsequently, when the water intake tank 120 is detected at a high water level through the water level detecting unit 152, the central processing unit 153 may generate the motor pump driving stop data and the unique identification code unit 155 for the detected high water level. Along with the designated identification code through the wireless transmission and reception module 154 is transmitted to the pump transmission and reception controller 140 located in the water supply area.

The motor pump transmission / reception controller 140 receives the motor pump driving stop data through the wireless transmission / reception module 144, and uniquely sets the motor pump driving stop data received by the central processing unit 143 by a predetermined program. The control unit determines whether the identification code unit 145 is identical to the designated identification code and outputs the controlled signal to the pump driving unit 141 to stop the motor pump 100 from being pumped any more.

The motor pump transmission and reception controller 140 inputs a stop signal of the motor pump 100 to the central processing unit 143 through the pump signal input unit 142, and stops the motor pump in the central processing unit 143. The data is transmitted to the intake tank transmission and reception controller 150 through a wireless transmission / reception module 146, and the water reception tank transmission and reception controller 150 is received through the wireless transmission / reception module 156 and the central processing unit 153. By recognizing that the motor pump 100 is stopped at, the intake tank transceiving controller 150 stops both the control operation and the water storage operation without transmitting the motor pump driving stop signal any more.

Subsequently, when the water level of the water intake tank 120 is lowered due to the use of water from the water intake tank 120, and the water level detection signal is input from the water level sensor 130 to the water level detection unit 151, the water intake tank transmission / reception controller At 150, the storage operation is performed while repeating the above operation process.

As described above, the present invention provides a two-way transmission and reception wireless data signal using a dedicated frequency between a motor pump of a water supply and a remote intake tank for storing water, and accurately recognizes and confirms an operation state of the motor pump and the intake tank. By controlling, it is possible to prevent water from being stored due to the abnormality of the motor pump or damage due to flooding.

In addition, the present invention can easily check the abnormal state by using a separate wireless receiver at home when the abnormality occurs in the motor pump and the water intake tank of the water source by the natural environment or other causes, to quickly respond to the occurrence of the abnormality It is possible to prevent the damage caused by long-term neglect of the abnormal state and the deterioration of the life of the device in advance to provide an effect that can prolong the life of the system.
