Detailed description of the invention

The first, rationally effective prosecution rule is formulated:

A, first formulate key parameter, these parameter values directly input through guidance panel:

1, current F is revealed in minimum tolerance _min, default value is 1; 2, maximum flow of inlet water F _max,default value is 7000; 3, clear stream F _qx, be used for determining conscious water, F accomplished _max/ 70>=F _qx>=F _min+ 10, default value is F _min+ 10; 4, ordinary faucet DN15 standard-sized sheet current F under usual pressure _dn, default value is 2000; 4, usual current F during solar energy water inlet pipe standard-sized sheet under pressure _tyn, default value is F _dn; 5, each water terminal cumulative maximum flow Q _max, default value is 50L, minimum 30 L, and maximum 100 L(according to circumstances can suitably amplify); 6, solar water container filling up water required time T _tyn, T _tyncan not be greater than 0.5 hour, default value is 0.25 hour.Current unit is: l/h, accumulated runoff volume unit is: rise, chronomere is: hour;

B, intermediate variable is set:

Work as F _qx> F > F _mintime the accumulated time T1 that starts; As F > F _mintime the accumulated time T2 that starts; F>=3/5 × F _tyntime the accumulated time T3 that starts; F>=F _qxaccumulation Q when entering water yield management and control state, current carried out; Current current accumulation limit value Q _lim, its initial value is Q _max; The previous stationary value F of current current _m, be used for determining the concrete state of water flow variation, F _minitial value be current discharge.Accumulated runoff volume unit is: rise, chronomere is: hour;

C, intermediate variable reset condition:

Misalign a variable to reset when system is in water yield management and control valve-closing process, under stable streamflow regime, perform following operation: T1, T2 are used for monitoring pipeline leakage, and initial value is 0, as F≤F _mintime, T1, T2 are reset; T3 is used for monitoring the upper water of solar water container and so on, as F≤1/5 × F _tynin time, resets T3; As F≤F _qxin time, resets Q; Definition is turned on the tap and is turned off the tap: if F-F _m>=1/2 × F _dnfor turning on the tap, if contrary F _m-F>=1/2 × F _dnfor turning off the tap, after said process judges, F _mbe set to F once, Q when current are turned on the tap _limincrease a Q _max, Q _limmaximum can not more than 2 Q _maxif within half an hour, current close several water tap just needs to reduce several Q _maxif action of not turning off the tap, then subtract a Q automatically _max, note Q _limcan not lower than Q _max, after having judged, all to perform a F _m=F, judges to do next time;

D, to reset to intermediate variable when system is in manual:

T1=0；T2=0；T3=0； Q=0；F _m=F；Q _lim=Q _max；

Valve rule is closed in E, formulation:

T1>1 hour or T2>10 hour or Q>Q _lim+ Q _maxthorough closedown automatic control valve, Q>Q _limand T3>T _tynor Q>Q _limand during T3=0, perform water yield management and control valve-closing process, misalign a variable when performing water yield management and control valve-closing process and reset, only have and just intermediate variable is resetted when system thoroughly closes valve or system is in manual;

F, water yield management and control valve-closing process:

After meeting valve-closing condition, first be send chimes of doom, if when after sending chimes of doom, in certain hour, current have a significant change, the Q of accumulation resets once, chimes of doom disappears, otherwise first cut out automatic control valve opens and points out at once, in case user does not hear chimes of doom, open again after stablizing and current are detected, if current are worth generation significant change before closing, can think to have people with water, the Q of accumulation resets once, valve is not closed, by artificial water or pipeline exception can be distinguished like this, if because of this person with run into during water current close time also need just to change pipeline water flow with water tap with water, recovery water is again eliminated or crosses after certain hour until chimes of doom, otherwise automatic control valve thoroughly turns off, misalign a variable to reset when being in water yield management and control valve-closing process, declare at this, carry out Simple communication than by wireless easy communication of carrying out with water flow variation, without the need to additional more equipment, and accurately, may there is blind area in wireless not necessarily transmitting-receiving,

G, similarly there is the process of solar water heater situation:

When being provided with solar energy and so on water tank and water tank volume is greater than Q _maxtime, there is Q>Q _limtime, see whether T3 is greater than T _tynif, T3>T _tyn, perform valve-closing process;

There is the process situation that valve explosion or feed pipe leak:

Solar energy water inlet pipe there will be continous way or pulsating water inlet pattern, be easy to when occurring that continous way is intake judge abnormal conditions, do not need too much elaboration, when leaking appears in solar water container water outlet side, solar water container pulsating similar to Figure 4 water inlet situation may be there is, intake several times continuously when solar energy rear end pipeline is abnormal regular: during water inlet, inflow is roughly equal several times, and the time is also roughly equal.As F>=4/5 × F _tyntime add up T _tynand Q _tyn, F≤1/5 × F _tynin time, stops adding up, if T _tynon1≌ T _tynon2; T _tYNoff1≌ T _tynoff2; Q _tyn1≌ Q _tyn2(Q _tyn1for T _tynon1the time water yield, Q _tyn2for T _tynon2the time water yield), can think when this situation occurs several times that solar energy exists and reveal, the action of water yield management and control valve-closing can be performed.

The second, according to above control strategy design hardware configuration:

As shown in Figure 1, after native system device 2 is arranged on family's water inlet main valve 1, what Fig. 2 showed is the concrete configuration of native system device: 3 is with central controller and driver element part, the main single-chip microcomputer referring to band programing function, can programme according to formulated prosecution strategy, 4 as system man-machine interface part, be responsible for parameter display, 5 is the operated key of some necessity, and 6 is electromagnetic valve or YE, and 7 is that current detect meter.Fig. 3 is intellectual water meter instrument board, and 8 is manual/auto changeover switch, and time manual, automatic control valve is initially open mode, 9 for arranging key, and 10 is electrodeless knob, and 11 is loudspeaker, 12 is viewing area, the value that instrument must show: (1), the key parameter required; (2), intermediate variable; (3), system specification; Other displays can be configured according to existing intellectual water meter.Key 9 is set and electrodeless knob 10 is used for arranging system core parameter, and by electrodeless knob 10 reading system parameter and systematic direction manual.For making system expand better, system wiring end is provided with alarm terminals, when the system alarm sound, terminal also closes.
