Description of drawings
Fig. 1 is the structural drawing of a kind of embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
With reference to figure 1, a kind of battery tension monitor, it comprises voltage detecting warning integrated circuit (IC), hummer HA, light emitting diode VL, resistance R 1, resistance R 2, small-sized solid potentiometer RP, electrolytic condenser C1, switch S and accumulator GB, and described potentiometer RP and resistance R 1 are connected in series and are connected in accumulator GB both positive and negative polarity by switch S; 8 pin power ends of voltage detecting warning integrated circuit (IC) are connected with accumulator GB is anodal by switch S; 5 pin electric capacity vibration end is connected with accumulator GB negative pole and ground connection by capacitor C1; 7 pin setting voltage input ends are connected with potentiometer RP positive terminal; 4 pin earth terminals are connected with potentiometer RP negative pole end and ground connection; 1 pin output end of pressure-stabilizing is connected in the anode of light emitting diode VL by resistance R 2, and the negative electrode of light emitting diode VL then is connected with 3 pin LED drive ends of voltage detecting warning integrated circuit (IC); The end of hummer HA is connected with anode by S, and the other end is connected with 6 pin logic level output terminals of voltage detecting warning integrated circuit (IC).
Described resistance R 1, resistance R 2 are selected the 1/4W carbon film resistor for use, and light emitting diode VL selects the high brightness LED of Φ 5mm for use, and hummer HA selects for use band to help the piezoelectric buzzer of the operatic tunes.
Principle of work of the present utility model: at the voltage of accumulator GB just often, 7 pin setting voltage input terminal voltages of voltage detecting warning integrated circuit (IC) are higher than internal reference voltage, its 6 pin logic level output terminal output high level, the output of 3 pin LED drive end no signals, this moment, light emitting diode VL did not work, and hummer HA does not ring.When the voltage of accumulator is lower than predetermined value, 7 pin setting voltage input terminal voltages of voltage detecting warning integrated circuit (IC) are lower than internal reference voltage, make the oscillator work of voltage detecting warning integrated circuit (IC) inside, oscillation pulse signal from its 3 pin LED drive end output certain frequency, make light emitting diode VL flicker luminous, drive signal from 6 pin logic level output terminal output low levels of voltage detecting warning integrated circuit (IC), hummer HA is sounded the alarm.
