Below in conjunction with accompanying drawing, the utility model is described in further detail:
1. general system proposal design
When each several part circuit is when there is something special, send low level alerting signal, after combiner circuit, produce low level signal, this signal divides 3 tunnels: the one, trigger onsite alarming system, scene is just known and is occurred leaking or electric leakage situation; The 2nd, trigger indoor GSM short message communication module, send alerting signal to master cellular phone, notify owner; The 3rd, this signal is delivered to security personnel's duty room call alerts system, person on duty just knows where sent warning demand by demonstration situation (showing and warning unit's correspondence one by one), and then visits and sue and labour and notify owner.See Fig. 1
2. water leakage alarm: discharge sensing circuit
Discharge sensing circuit is first with water flow sensor (including the current detection circuit that leaks), and it is to utilize the Hall effect of Hall element to measure Physics of Magnetism amount.Positive pole at Hall element seals in pull-up resistor, simultaneously the DC voltage of logical upper+5V and make direction of current and magnetic direction orthogonal.In the time that water promotes magnet rotor rotation by turbine switch housing, produce the rotating magnetic field of different magnetic poles, cutting magnetic induction is answered line, produces height impulse level.Because the output pulse signal frequency of Hall element is directly proportional to the rotating speed of magnet rotor, the rotating speed of rotor is directly proportional to discharge again, and therefore output pulse signal frequency is directly proportional to discharge again.
Discharge is divided into tri-sections of 0--Q1--Q2--, do not report to the police in 0--Q1 (Q1 is very little) section, Q1 – Q2 section as the stream section of leaking report to the police, be greater than Q2 current section as family or unit in the time normally making water, certainly also do not report to the police.Discharge sensing circuit is made up of four parts: the current detection circuit that leaks, 100 frequency multiplier circuits, frequency/voltage change-over circuit: tri-sections of discharge 0--Q1--Q2--are converted into voltage 0--V1 (V1 is very little) the most at last--tri-sections of V2--, window comparator circuit.Because window comparator has two turning points, therefore can accomplish that output low level is reported to the police within the scope of V1--V2, in the time being less than V1 and being greater than V2, export high level and do not report to the police.
See Fig. 3, water flow sensor 301 is received on the water inlet supervisor of family 302, while having water flow, it is output frequency signal, compare littlely with normal water due to normal conditions unit interval water leakage, therefore output frequency is lower, by 100 frequency multiplier circuits, frequency is improved to 100 times (according to circumstances, also can improve 10 times or N times), to ensure frequency-voltage conversion circuit work efficiency below.100 frequency dividing circuits that series connection is made up of counter CD4518 in the backfeed loop of phaselocked loop CD4060 if the frequency input signal of frequency multiplier is 1Hz～150Hz, just obtain the output frequency of 100Hz～15kHz after 100 frequencys multiplication.
The frequency signal fout of output delivers to the frequency-voltage conversion circuit being made up of LM331, see Fig. 4, in figure, LM331 is precise frequency voltage (F/V) converter, wherein R5=R6, U1, R5, R6 form phase inverter, incoming frequency is fi, and output voltage is Vo, and the pass of input and output is:
Wherein fi=0～15kHz, Vo=0～10V, nonlinear distortion are ± 0.01%.
Fig. 5 a is shown in by window voltage comparator circuit, Fig. 5 b is its transfer curve, as input signal Vi (being the Vo in Fig. 4) < V1 (can regard as cannot detect insignificant leaks or without leaking) or Vi > V2 (can regard family as and normally make water), output Uout is high level, does not report to the police;
As V1 < Vi < V2, output Uout is low level, reports to the police.
V1 and V2 obtain by resistance (potentiometer) dividing potential drop, by regulating RW1, RW2 with regard to capable of regulating V1 and V2.They correspond respectively to faint discharge (Q1) and the normal discharge lower limit Q2 using.
When actual debugging, first determine rational alarm stream weight range Q1～Q2, be the numerical value of Q1, Q2, conventionally Q1 is close to 0, determine respectively the numerical value of V1 and V2 according to the numerical value of Q1, Q2, in the time that flow is slightly larger than Q1, regulate RW1, RW2, make it just in time in critical alarm condition (output just transfers level "0" to from level"1"), V1 value is now corresponding to Q1 value; In the time that flow is slightly less than Q2, regulate RW1, RW2, make it just in time in critical alarm condition (output just transfers level "0" to from level"1"), V2 value is now corresponding to Q2 value; RW1, RW2 be to repeatedly adjust, the accurate corresponding Q1 of numerical value of V1 and V2, the numerical value of Q2 made.
Being less than Q1, for the non-detectable stream that leaks, being greater than Q2, is normal water, so do not report to the police;
Between Q1～Q2, be water leakage alarm section, report to the police.
Water flow sensor is received to the water inlet supervisor of family upper, when discharge is in Q1～Q2 scope, this circuit output level "0" is reported to the police.Now note: family can not low discharge water, in order to avoid false alarm.
3. leakage-current alarm: leakage current sensing circuit
As shown in Figure 6, TAN is zero sequence current mutual inductor, is again leakage current transformer, for detection of leakage current.When without electric leakage, in zero sequence current mutual inductor coil TAN, total magnetic flux is zero, and output voltage is 0, makes triode T cut-off, and finally exporting Uo is 1 level, and now leakage current warning circuit part is not reported to the police; In the time having leakage current; but while not exceeding family's earth leakage protective device action current value; at this moment switch for leakage protector is not jumped; in zero sequence current mutual inductor coil TAN, total magnetic flux is non-vanishing; just have Voltage-output, this Voltage-output after treatment, makes triode T saturation conduction; finally making to export Uo is 0 level, is used for reporting to the police.The leakage current concrete numerical value of reporting to the police is determined by circuit parameter.Zero sequence current mutual inductor is arranged on point of incoming cables in family's block terminal, allows phase line L and center line N through mutual inductor, and output line extracts.During without electric leakage, circuit output level"1" is not reported to the police; While having electric leakage, circuit output level "0" is reported to the police.
4. indoor warning circuit
