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, in rural areas or remote mountain ranges far from urban areas, water supply is still insufficient, and in these areas, groundwater or surface water is pumped up and stored in storage or intake tanks, and then remotely from the storage or intake tanks. It will use a small water supply system to supply the houses located.

In this way, 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 an intake tank for storing water while sensing the low water level of the pumped water at a distance from the motor pump of the water supply source, and the intake water. A controller is installed in the tank to control the motor pump when water is completed, and is configured to store water drawn from the motor pump into 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 or 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.

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

In the state where the 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. Referring to the storage process, the intake tank transmission and reception controller

In the central processing unit 153 of 150, the water intake tank through the water level detection input unit 151, 152

The water level state is input from the water level sensor 130 installed in the 120.

At this time, when the water level input signal is input from the water level sensing input unit 151 among the water level sensing input units 151 and 152 in the central processing unit 153, the central processing unit 153 currently has a water level in the intake tank 120. Determines that the water level is low and outputs it to the wireless transmission / reception module 154 through the data terminal DATA together with the identification code designated through the motor pump driving data and the unique identification code unit 155 to store the water intake tank 120. Done.

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 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. ) Controls the input wireless data while determining whether the input data signal matches the identification code specified from the unique identification code unit 145 by a predetermined program.

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 and pumps water from the motor pump 100 to the intake tank 120. It is stored through the water supply pipe (110).

At this time, the central processing unit 143 of the pump transmission / reception controller 140 receives the driving signal of the motor pump 100 through the input resistance R2, the bias resistor R3, and the zener diode ZD of the pump signal input unit 142. The pump driving data is transmitted to the wireless transmission / reception module 156 of the intake tank transmission / reception controller 150 through the wireless transmission / reception module 146 together with the identification code designated by the unique identification code unit 145.

Subsequently, when the water intake tank 120 detects the high water level through the water level detection input 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 pump transmission / reception controller 140 receives the motor pump driving stop data through the wireless transmission / reception module 144, and uniquely identifies the motor pump driving stop data received by the central processing unit 143 by a predetermined program. It is determined while matching with the identification code specified from the code unit 145 and outputs the controlled signal to the pump driver 141 to stop the motor pump 100 is no longer pumped.

In addition, the pump transmission / 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 the motor pump stop data in the central processing unit 143. Is transmitted to the intake tank transmission and reception controller 150 through the wireless transmission and reception module 146, the reception tank transmission and reception controller 150 is received through the wireless transmission and reception module 156, the central processing unit 153 By recognizing that the motor pump 100 is stopped, the intake tank transceiving controller 150 no longer transmits the motor pump driving stop signal and stops both the control operation and the water storage operation.

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 input unit 151, the water intake tank transmission / reception controller At 150, the storage operation is performed while repeating the above operation process.
