6) controller circuitry and supply module circuit are linked up, water pump is connected on the water pump input interface J3 of supply module, connect the 220V ac power supply and just can use.
Working principle of the present utility model:
When controller of the present utility model is worked, the P1.1 pin generation cycle of single-chip microcomputer is 2 seconds a square signal, single-chip microcomputer is in the current fluid level condition of the interscan in 1 second of P1.1 output low level, because when the P1.1 of single-chip microcomputer pin output low level, not conducting of chip (optocoupler) U5, signal will be exported electrical signal to netting twine by network interface, if this moment, 2 drink water purifying active carbon bags of certain liquid level level were all soaked in water, high level signal can make triode Q1 (8050) conducting by the loop, thus single-chip microcomputer according to programme and just can distinguish that fluid level condition comes the operation of control of pump.Operate in auto state at ordinary times, when liquid level is lower than minimum value (8 bag drink water purifying active carbon bags are exposed in the air).At this moment, the level that single-chip microcomputer is gathered P1.7, P1.6, P1.5, P1.4 is high, program by single-chip microcomputer inside allows P3.0, P3.1, P3.4 and P3.5 export high level, make the LED lamp (diode D1, diode D2, diode D3, diode D4) of four indication liquid levels go out entirely, buzzer (being loudspeaker) in the controller has the continuous sound (representative lack of water) in 3 seconds, and controller output control signal makes water pump draw water to water tower simultaneously.When liquid level arrives peak (8 bag drink water purifying active carbon bags are all under water), the level that single-chip microcomputer is gathered P1.7, P1.6, P1.5, P1.4 is low, program by single-chip microcomputer inside allows P3.0, P3.1, P3.4 and P3.5 output low level, make that the LED lamp of four indication liquid levels is bright entirely, the buzzer in the controller has the interruption sound in 3 times 1 seconds.Exporting control signal simultaneously stops pumping water pump.When the user thought manually-operable, the user can start or stop water pump operation according to the needs of oneself.For example: when the liquid level tutorial light has two bright (below 4 bag drink water purifying active carbon bags of liquid level level under water), at this moment, the level that single-chip microcomputer collects P1.7, P1.6 is low, the level of P1.5, P1.4 is high, if the user thinks that water is not enough, just can just can start water pump by the key that draws water, liquid level when liquid level reaches requiring of user, the user can just can allow water pump stop pumping by the key that stops pumping.In above process, liquid level all is to show in real time, and the user is very clear just can to know in own home's the water tower on earth how much water in addition.Simultaneously, in this process, active carbon bag under water carries out purified treatment to water, and the active carbon bag can sop up airborne harmful gas in the water tower in the air and be exposed at; Having liquid level shows and water purification function.So it will be healthy water that the user drinks, fresh water.
The utlity model has following advantage:
(1) purified treatment of potable water:
This controller is the conductor that adopts the drink water purifying active carbon to detect liquid level and transmit as signal.Exactly because active carbon can adsorb various harmful gases, organic chemical pollutant matter, heavy metal ion in air or water, can eradicate the potential carcinogen trichloromethane (chloroform) that tap water produces because of chlorination, and energy decolouring, taste removal, filtering bacterium and suspended matter, suppress the generation of bacterium, also kept the needed various mineral substance of human body simultaneously.And high temperature resistant (under 1000 ℃ of conditions of high temperature, can not burn), can be heat insulation, acid resistant alkali, can conduct electricity, the 5-10 that can grow up the recycling time can be widely used in air purification, water treatment, medical health care products, sports equipment, automobile making, and even national defense industry numerous areas, the use value height, many characteristics of applied range make it to have possessed the purpose of purifying waste water simultaneously in this system.
The use of this controller can make the user drink health, fresh water like this, significantly reduces owing to water pollutes the various diseases that causes.
(2) need not to increase any sensor, can realize the measurement of liquid level:
Active carbon has satisfactory electrical conductivity and don't can electrolysis in water, when drink water purifying active carbon bag is under water, utilizes the electric conductivity of water, forms the loop of signal naturally, just can not obtain electrical signal acquisition liquid level information so need not increase any sensor.Utilize this controller can show the liquid level of water tower (water tank) in real time, saved the cost that to buy sensor, also do not have sensor installation and maintenance problem simultaneously than traditional piston type domestic water pump controller.
(3) the signal transmission is easy to be reliable:
Signal transmssion line between controller indoor and outdoors part adopts straight through cable (signal transmssion line 2), and the netting twine antijamming capability is strong, and price is also relatively more cheap, and netting twine is installed very convenient simultaneously.Signal input interface on the controller is exactly a network interface, as long as stayed a Network Cable Connector, user only to need on request netting twine to be accomplished directly to be inserted on the Network Cable Connector and just can to use in the common crystal head at the top of water tower.Utilize netting twine simultaneously, maximum level progression shows can reach 7 grades, more accurate than 4 grades, 5 grades water levels demonstrations of traditional piston type domestic water pump controller.
(4) water-saving and electricity-saving:
Current, our on the one hand hydroelectric resources shortage of country exists serious hydroelectric resources wasting phenomena on the other hand.According to the data introduction, global water has 93 percent to be salt water, and 7 percent is fresh water, and the water that can drink has only 0. 8 percent; Concerned power, many local electricity shortages, it is bigger to load, and the peak electricity consumption period is carried out power cuts to limit consumption, and the most basic electric consumption on lighting all is difficult to ensure.
" water is arranged when thinking anhydrous hardship, electricity is arranged when thinking not have pain of electricity ", water is Source of life, and the energy is the power of human development; The sustainable use of the water and the energy is the basis of social development, is to build a well-off society in an all-round way and realize modern important leverage.Do not use water pump controller and power on and draw water by artificial water supply's pump, the completely back water situation of overflowing of water tower often can occur, this phenomenon electricity wasting of promptly wasting water causes extra economic burden for some family.Use this controller to solve the above problems well.
(5) intelligent control: can select automatically or manually boot and switch off the pump according to user's needs.
(6) in the controller buzzer has been installed, can have been sent various prompt tones according to fluid level condition.(as lack of water, water has been expired or the like).
(7) active carbon can reuse for up to 5-10, the user can change drink water purifying active carbon bag (preferably being about 5 centimetre plastic water pipe along the hollow and diameter that punches on every side fixes) at any time according to the needs of oneself, changes to make things convenient for.
