Embodiment

As Fig. 1, shown in Figure 2, intelligent residential district of the present utility model water power supervising device, comprise line voltage testing circuit 1, water storage tank water level detection circuit 2 and single chip machine controlling circuit 3, the signal that described line voltage testing circuit 1 is gathered exports GSM short message receiving-transmitting circuit 31 to through single chip machine controlling circuit 3 controls, GSM short message receiving-transmitting circuit 31 and single chip machine controlling circuit 3 bidirectional data communications, the signal that described water storage tank water level detection circuit 2 is gathered sends to single chip machine controlling circuit 3 through comparator circuit 21, exports reserve tank driving circuit for electromagnetic valve 32 to by single chip machine controlling circuit 3 controls.

Described line voltage testing circuit 1 connects voltage transformer (VT) B by the output of AC220V loop, the 2.2V ac voltage signal of B level output of voltage transformer (VT) sends to rectification, filtering, the adjustment circuit constitutes, as live wire L1, when zero line N constitutes the AC220V loop, B level of voltage transformer (VT) was with 100: 1 output 2.2V ac voltage signals, this signal is through diode D1 rectification, capacitor 1C1 filtering, resistance 1R1 current limliting, adjust adjustable resistance W1 and be used for check and correction and the linear output of input voltage, the 33rd pin I/O end of this voltage signal input single-chip microcomputer IC1, after single-chip microcomputer IC1 internal processes is judged, do not send control signal.When line voltage is lower than 110V, the following ac voltage signal of voltage transformer (VT) B level output 1V, this signal is after diode D1 rectification, be input to single-chip microcomputer IC1 the 33rd pin I/O end and be low level state, be judged as power fail or power failure through single-chip microcomputer IC1 internal processes, by the 7th of GSM short message transceiving module IC2 and single-chip microcomputer IC1,8,27,14 pin are formed datel circuit, send the driving data instruction by single-chip microcomputer IC1 to GSM short message transceiving module IC2, GSM short message transceiving module IC2 sends to the owner and has a power failure or the power fail warning message, notifies the owner to carry out work of treatment.

When GSM short message transceiving module IC2 receives cutting off the water during notifying messages of property department, after the inner decoding of GSM short message transceiving module IC2, send data to single-chip microcomputer IC1, single-chip microcomputer IC1 reading of data is after internal logic is judged, the current potential of its 37th, 34 pin I/O is read in scanning, when after scanning, finding to be in electronegative potential, illustrate that cistern water level is full, single-chip microcomputer IC1 does not export driving signal makes solenoid valve open valve.

Described water storage tank water level detection circuit 2 is made of lack of water point exploring electrode A, low-water level point exploring electrode B, the water exploring electrode C that works to the last minute, as lack of water point exploring electrode A, when low-water level point exploring electrode B point is not invaded in water, GSM short message transceiving module IC2 receives note, and single-chip microcomputer IC1 detects the noble potential that its I/O the 37th, 34 pin are read in scanning.When input voltage is 0V, direct supply voltage is through resistance R 1 current limliting, the 3rd pin current potential that is input to LM358 comparer IC3/A also is zero, this moment, LM358 comparer IC3/B the 5th pin current potential was provided with current potential when high than the 3rd pin of LM358 comparer IC3/A, the upset of LM358 comparer IC3/B internal circuit, by its 7th pin output high level signal, at this moment, by the 32nd pin output noble potential of single-chip microcomputer IC1, through resistance R 10 current limlitings, make triode Q1 conducting, the relay J adhesive, its contact J-1 transfers normally closed point to, promotion solenoid valve M opens valve and begins to the water tank water filling, the 25th pin output low level of single-chip microcomputer IC1 through resistance R 11 current limlitings, makes news Chinese percussion instrument YD send alarm sound simultaneously, illustrate just in water filling, after 10 seconds, the output high level signal makes news Chinese percussion instrument YD stop to send chimes of doom through single-chip microcomputer IC1 internal delay time.When water level is added to water when working to the last minute exploring electrode C point, supply voltage is through the R1 current limliting, be input to the 3rd pin of LM358 comparer IC3/A, the 3rd pin current potential of LM358 comparer IC3/A is than LM358 comparer IC3/B the 5th pin current potential height, LM358 comparer IC3/A upset, the 1st pin of LM358 comparer IC3/A transfers electronegative potential to by original noble potential, single-chip microcomputer IC1 detects scanning the 37th, when 34 pin I/O end all is in low level, single-chip microcomputer IC1 the 32nd pin output low level, make triode Q1 be in cut-off state, relay J discharges, solenoid valve M dead electricity, stop to supply water, reach the purpose of Intellectualized monitoring water power.

Above-described only is a preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
