Embodiment
Shown in Fig. 1, novel intelligent ammeter alarm comprises intelligent electric meter, is made up of power supply, light-operated circuit, time circuit, ammeter control circuit and warning circuit, connects through lead therebetween, and all elements are installed in the intelligent electric meter.Power supply is made up of a power transformer, four silicon rectifier diodes, an electrochemical capacitor, two ceramic disc capacitors, a fixing output three terminal integrated voltage stabilizer and a power switch, connects through lead therebetween.Light-operated circuit is made up of a photo-resistor, a NPN triode and an electrochemical capacitor, connects through lead therebetween, when photo-resistor is installed in the intelligent electric meter, should expose the outside at the intelligent electric meter housing to its sensitive surface.Time circuit is made up of a time-base integrated circuit, a resistance, a trimmer potentiometer, a transwitch diode, an electrochemical capacitor and a relay, connects through lead therebetween.The ammeter control circuit is made up of intelligent electric meter inner own circuit, a NPN triode and a relay, connects through lead therebetween.Warning circuit is made up of a warning integrated circuit, a PNP triode and a loudspeaker, connects through lead therebetween.
Like Fig. 2, by power transformer T; Silicon rectifier diode VD1, VD2, VD3, VD4; Electrochemical capacitor C1; Ceramic disc capacitor C2, C3; Fixing output three terminal integrated voltage stabilizer A1 and power switch S form power supply.By photo-resistor RL; NPN triode VT1 and electrochemical capacitor C4 form light-operated circuit.By time-base integrated circuit A2; Resistance R; Trimmer potentiometer RP; Transwitch diode VD5; Electrochemical capacitor C5 and relay K 1 makeup time circuit.By the inner own circuit A3 of intelligent electric meter; NPN triode VT2; Relay K 2 is formed the ammeter control circuit, and VD6 is the warning light emitting diode on the A3.Form warning circuit by warning integrated circuit A4, PNP triode VT3 and loudspeaker B.In Fig. 2, the 220V AC power is through T step-down, VD1, VD2, VD3, VD4 rectification; C1 filtering converts 12V direct supply input A1 into; Convert stable 5V direct supply into through the A1 voltage stabilizing, the effect of C2 is to change the power supply ripple characteristic, and the effect of C3 is a transient response of improving load.When the 5V direct supply of A1 output was imported RL, at night, the sensitive surface of RL was because unglazed photograph is high resistance, and VT1 is in cut-off state, and subsequent conditioning circuit is not worked; In the time of by day, the sensitive surface of RL is owing to there is its resistance of illumination to descend rapidly, and VT1 gets into conducting state, and subsequent conditioning circuit gets the electrician and does, and the effect of C4 is the interchange internal resistance when eliminating the VT1 conducting.After the VT1 conducting, RP charges to C5, and when just beginning, the 2nd pin of A2 is an electronegative potential, and A2 set makes the 3rd pin output noble potential, so K1 gets its normally opened contact closure of electric adhesive; After about 36 seconds, the last terminal potential of C5 (i.e. the 6th pin current potential) rises to supply voltage three/two o'clock, and A2 is reset, and its 3rd pin output electronegative potential is so the K1 dead electricity is broken off.In Fig. 2, ammeter control circuit working power adopts the inner own 5V direct supply of intelligent electric meter; In using intelligent electric meter, if expense is about to use up, A3 can export the control power supply and light VD6 and remind the user to fill expense; When A3 output control power supply was lighted VD6, the power supply of output amplified through the VT2 electric current that power supply makes it to such an extent that its normally opened contact of electric adhesive is closed to K2.Because the working power positive pole of warning circuit is to supply with through the normally opened contact of K1 and K2; So export noble potential about 36 seconds at its 3rd pin of A2 set; K1 gets the closed and A3 output control power supply of its normally opened contact of electric adhesive; K2 supply power under the closed situation of its normally opened contact of electric adhesive, warning circuit will get the electrician and do.After warning circuit got electrician's work, through the VT3 power amplification, driving B sent alarm song loud about 36 seconds and reminds the user to fill expense A4 from the 2nd pin output audio signal.Under the effect of above circuit, if the intelligent electric meter customer charge is about to use up, the utility model will be on daytime every day, sends about 36 seconds loud alarm sound through B and reminds the user to fill expense, if do not need to remind, only need close S and get final product; And the sufficient user of expense, because A3 does not export the control power supply, K2 just can not get electric adhesive, warning circuit can not worked yet.
