The present invention is when using first, and system needs a learning process, so that the water tank volume of record solar energy water heater.If sun power is furnished with ball-cock assembly, learning process is finished automatically.Under the situation of not being furnished with ball-cock assembly, need artificial cooperation in this process.
The present invention requires the sun power water supply pipeline unimpeded when first the use, can normally go up water, and solar water container is in the emptying state, so that the present invention can finish the automatic calculating to water tank capacity automatically.
The present invention is provided with 3 modifier keys, as shown in Figure 3.Button S1 is " manually waking up " button, and S2 is " using first " button, and S3 is " it is full to go up water " button." manually waking " button S1 up is usually used in not being furnished with ball-cock assembly and is furnished with the semi-automatic water of going up under solenoid valve (the mode 1 of the present invention) situation; " use " button S2 to be used for the initializing set value first, " it is full to go up water " button S3, be used for not being furnished with ball-cock assembly and be furnished with under solenoid valve (the mode 1 of the present invention) situation, artificial reporting system " solar water container is filling up water " when using first, so that the setting value that system log (SYSLOG) is new is closed solenoid valve simultaneously.
Below in conjunction with Fig. 4 and with reference to figure 3, describe the course of work of the present invention and step in detail.
1, " powers on, opens solenoid valve "
When powering on, behind the single-chip microcomputer electrification reset, the program that is solidificated in the single-chip microcomputer is carried out initialization, sends simultaneously and opens the solenoid valve instruction, and making the P1.6 (18 pin) of Chip Microcomputer A tmel89c2051 is high level, and LED3 goes out.Although selected is normal-open electromagnetic valve, to guarantee that also solenoid valve is in open mode when powering on, unimpeded to guarantee the sun power water supply pipeline, so that go up water; System power-on reset wakes Single Chip Microcomputer (SCM) system up automatically, makes single-chip microcomputer be in the water monitor state.
If upper hose does not have current (may owing to water meter main valve reason such as do not open cause) at this moment, then single-chip microcomputer enters dormant state.
2, go up the water monitor state
Last water monitor state is divided into two kinds of situations, promptly " uses " situation and " non-use first " situation first.
" use " under the situation storer E of record " setting value " first
2What store among the PROM 24C01 is that particular value " 0FFFFFFFFH " represents that the water tank capacity of sun power is for infinitely great.Last water process is by microcomputer monitoring, and the last water yield is measured by single-chip microcomputer, and in this process, the P1.7 of single-chip microcomputer is output pulse signal periodically, and LED1 is glittering, constantly allows the CD4060 zero clearing, and the Q4 of CD4060 is output as low level, and triode V2 ends.
Be furnished with under the situation of ball-cock assembly, during water tank waterborne full, ball-cock assembly is under buoyancy function, automatically close, last water stops, in the setting-up time by the control of the timer T0 in the single-chip microcomputer, single-chip microcomputer detects less than the pulse signal by the water flow sensing unit input, and single-chip microcomputer just stores the flow value that is write down into E automatically
2In the prom memory, as new setting value (being different from initial set value).The clear water gauge will that goes up, send the dormancy instruction, make single-chip microcomputer be in dormant state, at this moment, the P1.7 of single-chip microcomputer is a low level, and LED 1 is bright, 12 pin (RESET) of CD4060 are low level, be in normal count status, for waking single-chip microcomputer up, so that be that next real-time monitoring of going up the water process is got ready.
Under the situation of not joining ball-cock assembly, use first and will whether go up full by the water of manually judging water tank according to refluxing.When waterborne expiring, manually press " waterborne full " button in good time, at this moment single-chip microcomputer at first cuts out solenoid valve, and LED3 is bright, stops to go up water, under the situation of not being furnished with solenoid valve, should close manual ball valve in good time; At this moment single-chip microcomputer just stores the flow value that is write down into E automatically
2In the prom memory, as new setting value (being different from initial set value).The clear water gauge will that goes up is sent the dormancy instruction, makes single-chip microcomputer enter dormant state.At this moment, the P1.7 of single-chip microcomputer is a low level, and LED1 is bright, and 12 pin (RESET) of CD4060 are low level, are in normal count status, breaks away from dormant state for making single-chip microcomputer, so that ready to monitoring of water process on the next one.
Under " non-first use " situation, last water monitor procedure is that the dormant state from single-chip microcomputer begins.Be at single-chip microcomputer under the situation of dormant state, the current of upper hose drive the turbine rotation in the water flow sensing unit 1, the water flow sensing unit output pulse signal, and wake-up circuit is counted this pulse, and the purpose of counting is in order to improve the antijamming capability of system.If water flow sensing unit 16 pulses of output continuously, i.e. the normal water of going up of expression, the 7 pin Q4 output high level of CD4060, by diode D2, resistance R 9, resistance R be makes triode V2 conducting, and capacitor C 1 is discharged rapidly by triode V2.When water flow sensing unit continues to output to the 32nd pulse, the 7 pin Q4 of CD4060 are output low level again, and triode V2 ends, and power supply passes through R7, C1, form a positive pulse signal on R11, RST (the 1st pin) end by diode D1 delivers to single-chip microcomputer resets single-chip microcomputer, wake single-chip microcomputer up, make single-chip microcomputer enter monitor state, put water gauge will, and the last water yield is measured.
Enter in the monitor procedure at single-chip microcomputer, wake-up circuit serves as " house dog " circuit, and single-chip microcomputer can be periodically from P1.7 (the 19th pin) output pulse signal (feeding-dog signal), to guarantee that single-chip microcomputer normally moves in program operation process.
Under " non-use first " situation, the water level in the solar water container can be owing to water reduces, and ball-cock assembly is opened under the effect of gravity, automatic loading water.Because the discontinuity of water, the last water yield in each monitor procedure can not surpass the setting value of using first.Be no more than in the last water yield under the situation of setting value, if the full ball-cock assembly of water is closed, stop to go up water, then single-chip microcomputer sends the dormancy instruction, enters dormant state.
If because watering pipeline breaks, the accident phenomenon of metalling run out appears, and watering pipeline will be gone up water continuously, and the last water yield can exceed setting value (water tank volume that is measured when using first), and at this moment single-chip microcomputer will send alerting signal, closes solenoid valve.The purpose of sending alerting signal is to allow the user note getting rid of pipeline fault, and the purpose of closing solenoid valve is the waste of to metal run out and being caused in order to reduce.Alerting signal is that LED2 is glittering, and alarm LS1 sends alarm sound.
Beneficial effect: solar water heater watering pipeline Based Intelligent Control alarm of the present invention, comprise " water flow sensing unit " that be connected in the watering pipeline, be connected " electromagnetic valve " in the water supply line and be connected sensor and electromagnetic valve between " single-chip computer control system ", also comprise the sound device that is used to report to the police, as loudspeaker, music integrated circuit etc.
1, the water flow sensing unit that is connected in the watering pipeline is made up of turbine that is fixed with magnet steel and housing.The outside of housing is fixed with hall device, and housing constitutes the part of pipeline.When last water, because the mobile drive turbine rotation of water, thereby the magnet steel that is fixed on the turbine also and then rotates.When magnet steel forwarded the hall device correspondence position to, hall device produced pulse.On behalf of water, the pulse that is produced both begin or had been gone up water, also can be used for the metering to the last water yield.That is to say that this sensor promptly can be used as water flow sensing unit, also can be used as flow sensor, thereby cooperate and to measure the last water yield with single-chip microcomputer.
2, Single Chip Microcomputer (SCM) system is used for receiving the pulse signal that " water flow sensing unit " sends, and judges different situations such as " beginning to go up water ", " going up water continuously ", " stopping to go up water ".Under the normal condition, on continuously under the water state on the water yield measure, when the last water yield reaches or be less than set amount (corresponding with the sun power volume), if continue to detect the pulse signal that sends less than " water flow sensing unit " in Single Chip Microcomputer (SCM) system a period of time, illustrate that water stops, at this moment single-chip microcomputer sends the dormancy instruction, and single-chip microcomputer just enters dormant state automatically, reaches the purpose of economize on electricity; When the last water yield surpasses set amount, and single-chip microcomputer is when detecting still on continuing water, illustrating has the phenomenon of metalling run out to take place on the watering pipeline, single-chip microcomputer sends closes the solenoid valve instruction that is connected in the water supply pipeline, close electromagnetic valve, and send " sound, light " alerting signal, get rid of up to fault, in order to avoid cause the waste of metalling run out.
3, the dormancy awakening of Single Chip Microcomputer (SCM) system is finished automatically by the pulse signal driving wake-up circuit of water flow sensing unit output.When Single Chip Microcomputer (SCM) system was in dormant state, the pulse signal of water flow sensing unit output resetted single-chip microcomputer through wake-up circuit, thereby made single-chip microcomputer enter " monitoring and state of a control ".

(mode 1) as shown in Figure 1, it is made up of water flow sensing unit 1, single-chip computer control system 2, warning device 3, solenoid valve 4, watering pipeline 5.Be applicable to the watering pipeline monitoring or the warning of the solar water heater of being furnished with ball-cock assembly or the solar water heater of not being furnished with ball-cock assembly.If solar water heater is furnished with ball-cock assembly, solenoid valve only plays booster action under the normal condition, at this moment can adopt mode 2 (as shown in Figure 2), can save solenoid valve.
Solar water heater watering pipeline Based Intelligent Control alarm, its course of work as shown in Figure 4, solenoid valve is selected open type for use, when the sun power filling up water, stops to go up water automatically by ball-cock assembly, the present invention plays last water and watering pipeline monitoring effect.In case because pipeline breaking is metalled run out above the sun power capacity, Single Chip Microcomputer (SCM) system detects also water on continuing of watering pipeline, then single-chip microcomputer sends failure alarm signal immediately, and closes solenoid valve automatically, gets rid of up to fault.
When water when the water flow sensing unit, water flow sensing unit will output pulse signal, on behalf of watering pipeline, this pulse signal not only go up water, on behalf of a certain amount of water, each pulse signal also flow out from water flow sensing unit.Therefore, utilize this water flow sensing unit not only can detect the last water state of watering pipeline, also can cooperate single-chip microcomputer that the last water yield is measured.
Implementation system figure as shown in Figure 1 and Figure 2, the schematic diagram of single-chip computer control system 2 wherein is as shown in Figure 3.Be elaborated below in conjunction with 3 pairs of principle of work of the present invention of schematic diagram.Used single-chip microcomputer is Atme189c2051 among Fig. 3.By CD4060 and peripheral resistance R 7, R8, R9, R11, Rbe thereof, LED 1, triode V2, capacitor C 1, diode D1, D2 have constituted the reset circuit and the dormancy awakening circuit of single-chip microcomputer.When powering on, the 7th pin (Q4) of CD4060 is output as low level, make NPN triode V2 be in cut-off state through resistance R 9, Rbe, power supply VCC is through resistance R 7, capacitor C 1 forms the positive pulse of a width greater than 10ms on resistance R 11, pass to 1 pin (RST) of single-chip microcomputer through diode D1, single-chip microcomputer is resetted, enter normal working procedure.Single-chip microcomputer is periodically given the 12nd pin (RESET) the input positive pulse signal of CD4060 by P1.7 (the 19th pin) in program operation process, make the counter outputs at different levels " 0 " of CD4060, and promptly keeping the 7th pin is low level, and triode V2 is in cut-off state.R1 serial connection LED1 is as the pull-up resistor of single-chip microcomputer P1.7, P1.7 also provides drive current for LED1 when low level simultaneously, the size of drive current is subjected to the restriction of R1, because the mouth line of single-chip microcomputer can provide the filling electric current of 20mA, so R1 can select 100 Ω-400 Ω, satisfy the normal luminous requirement of LED1, the normal bright expression single-chip microcomputer of LED1 is in dormant state, and glittering expression single-chip microcomputer is in the monitoring state.The pulse signal of the 3rd pin output of Hall element 1-3 (A1141) divides two-way, one the tunnel directly imports the counting pulse signal of the 11st pin (external pulse input pin ZI) of CD4060 as CD4060, the 6th pin (P3.2/INT0) of single-chip microcomputer is sent on another road through resistance R 5, NPN triode V1, the INT0 interrupt response program of single-chip microcomputer is counted this pulse signal, and as the foundation of the water yield on the solar water heater.When the last water yield reached setting value, the P1.6 output low level of single-chip microcomputer made the V3 conducting, and attracting electric relay closes and closes water solenoid valve, P3.7 driven for emitting lights diode (LED) 2 Chang Liang, and expression water has been gone up full, and has stopped going up water.If there is not solenoid valve, automatic pass is closed water and is finished by ball-cock assembly.Judging water when single-chip microcomputer upward expires, and water flow sensing unit still has count pulse output, and then P1.2 output high level triggers the hummer sounding, and P3.7 driven for emitting lights diode (LED) 2 glimmers, and represents that watering pipeline breaks down, and need manually fix a breakdown.Under normal circumstances, after waterborne expiring, ball-cock assembly on the solar water container can be closed automatically, and last water stops, and single-chip microcomputer is when water has stopped on detecting, putting P1.7 is low level, make CD4060 be in normal count status (because water flow sensing unit is not exported count pulse when Shang Shui stops, in fact CD4060 is in the countless states of counting at this moment), at this moment LED1 Chang Liang, single-chip microcomputer sends dormancy (Idle) instruction simultaneously, enters dormant state.Single-chip microcomputer is under the dormant state situation, if because water, cause the solar water container water level to reduce, at this moment ball-cock assembly is opened under action of gravity automatically, last water begins, hall device 1-3 (Hall1) output pulse signal makes the CD4060 counting, and at this moment square-wave signal will appear in the 7th pin (Q4) of CD4060, between the high period of square-wave signal, triode V2 conducting makes capacitor C 1 discharge, and between the low period of square-wave signal, triode V2 ends, power supply is by resistance R 7, and R11 gives capacitor C 1 charging, produces a positive pulse simultaneously on resistance R 11, arrive the reset terminal of single-chip microcomputer by diode D1, single-chip microcomputer is resetted, wake single-chip microcomputer up, make single-chip microcomputer in the monitoring state.If adopt mode 1 as shown in Figure 1, solenoid valve promptly is housed on water supply pipeline, and for a certain reason (as, pipeline breaking fault or pipeline do not have ball-cock assembly will lean on the artificial situation that goes up water) closed solenoid valve automatically, then can manually wake single-chip microcomputer up by manually waking button S1 up, open electromagnetic valve simultaneously, realize the artificial water of going up, monitoring automatically.
