Realize the monitoring to system.
The water level in water tank is detected by the first liquid level sensor, the first water level value of acquisition is sent to control
Device processed, controller determine whether water tank water filling according to first water level value, when needing then to control during water tank water filling
One magnetic valve is opened, and controls the first transducer drive pump motor to start and the water in well is injected into water tank, when
Then control the first closed electromagnetic valve when need not be water tank water filling, and control the first frequency converter to be stopped, so as to stop to
Water tank water filling, domestic water-storage system is automatically controlled so as to realize, brought great convenience for user, improves work
Efficiency, reduce the waste of water resource and electric power resource.
The embodiment of the invention discloses a kind of control device of domestic water-storage system, relative to a upper embodiment, this implementation
Example has made further instruction and optimization to technical scheme.Specifically：
Fig. 2 is refer to, Fig. 2 is that the structure of the control device of another domestic water-storage system provided in an embodiment of the present invention is shown
It is intended to.
Whether there is enough water to be irrigated into water tank because the number of reservoir storage in well is directly connected to, therefore
Reservoir storage in well can also be detected, it is specific as follows：
Further, said apparatus can also include being arranged inside well, output end and the 5th end of controller 1 connects
The second liquid level sensor 6 connect, for detecting the water level in well, and the second water level value is obtained, so that controller 1 is according to first
Water level value and the second water level value determine whether to control being turned on and off for the first magnetic valve 4 and the first frequency converter 3.
It should be noted that the second liquid level sensor 6 can also be set in well, second liquid level sensor 6 is used for
Water level in well is detected, and the second acquired water level value is fed back into controller 1, controller 1 can be according to this
Second water level value is judged the water in well, when the water in well is more than a certain preset value, or the second water level
When value is more than four predetermined threshold values, then illustrate that the water in now well is more abundant, if now judging by the first water level value
Water in water tank is less, i.e. the first water level value is less than the first predetermined threshold value, then can now control the first magnetic valve 4 to open
Opening, the first frequency converter 3 of control starts, the further water filling into water tank, namely only when the second water level value corresponding to well is big
In the 3rd predetermined threshold value, and when the first water level value corresponding to water tank is less than the first predetermined threshold value the ability control system of controller 1 to
Water filling in water tank, other situations stop the water filling into water tank.
In order to further provide the user safe and reliable domestic water, the water quality of the water in well can also be examined
Survey, to ensure water safety, provide the user the domestic water of high quality.
Further, in addition to be arranged inside well, output end and controller 1 six end connecting water quality inspection
Instrument 7 is surveyed, for detecting the water quality of well reclaimed water, and water quality detection value is obtained, so that controller 1 is according to the first water level value, second
Water level value and water quality detection value determine whether to control being turned on and off for the first magnetic valve 4 and the first frequency converter 3.
It should be noted that the water quality testing meter 7 in the embodiment of the present invention is used to analyze water quality component content in well, it is main
If it is to pass through electrification to measure information, its principle such as BOD, COD in well, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, PH, dissolved oxygen
Learning reaction or chemical agent reaction makes the respective substance in water participate, and is then calculated by modes such as conductivity measurements
The content of respective substance in water, in actual applications, the water quality testing meter 7 can be fixedly mounted on apart from well shaft bottom 30cm
Place, the scope of measurement is 0-40 DEG C, and the data message that water quality testing meter 7 detects can turn RS-485 strings by configuring RS-232
Oral instructions are transported in PLC, so that PLC is controlled water storage system accordingly according to corresponding data message.
Specifically, can when the first water level value less than the first predetermined threshold value, the second water level value higher than the 3rd predetermined threshold value and
When water quality detection value is less than corresponding predetermined threshold value, can control the first electronic valve open, control the first frequency converter 3 start so as to
The water filling into water tank；When the first water level value is less than the 3rd predetermined threshold value or water quality higher than the first predetermined threshold value or the second water level value
When detected value exceedes preset standard value, then controller 1 controls the first electronic valve to close, and the first frequency converter 3 of control is stopped, with
Stop the water filling into water tank.
More specifically, the control device can also include the second frequency converter 8, electric pump machine 9, second solenoid valve 10 and pharmacy jar
11, wherein：
7th end of controller 1 is connected by the second frequency converter 8 with the drive end of electric pump machine 9, and electric pump machine 9 is used to drive medicine
Purifying agent for polluted water in agent tank 11 flows into well by second solenoid valve 10；
The control terminal of second solenoid valve 10 is connected with the 8th end of controller 1, for when the control for receiving the transmission of controller 1
Opened after system instruction.
It should be noted that when the water quality detection value in well exceedes preset standard value, then now need in well
Water carry out purified treatment, specifically can by controller 1 control the second valve opening, control the second frequency converter 8 start, pass through
Second frequency converter 8 driving electric pump machine 9 works, and electric pump machine 9 can lead to the purifying agent for polluted water prestored in pharmacy jar 11 after working
It is injected into after crossing the second electronic valve in well, purified treatment is carried out to the water in well so as to realize, to improve well reclaimed water
Water quality, and when the water quality detection value in well reaches water standard, i.e., less than corresponding predetermined threshold value when, then pass through control
First magnetic valve 4 and the first frequency converter 3 are opened so as to the water filling into water tank, to ensure the safety of the water injected into water tank
Property.
In addition, the second frequency converter 8 in the embodiment of the present invention can control on the spot with unified being arranged on of the first frequency converter 3
In cabinet, switch board can be arranged at 3~5 meters of well, and certainly, specific distance can be determined according to actual conditions,
The application does not do special restriction to this.
More specifically, the control device of domestic water-storage system described above, can also include connecting with the input of controller 1
The touch-screen connect, for receiving the option information of user's input, and option information is sent to controller 1, so as to the control
Device 1 controls corresponding equipment according to the option information.
It should be noted that the touch-screen in the embodiment of the present invention is used for man-machine interaction, the touch-screen can be arranged on
Position pusher side, is placed in user's control room, and because touch-screen and controller 1 are provided separately, PLC is installed at the scene, and two
