Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
As shown in Figure 1, 2, the utility model comprises current rectifying and wave filtering circuit, voltage stabilizing circuit, controlled battery feed circuit, the input of the output termination voltage stabilizing circuit of current rectifying and wave filtering circuit, the output of the input termination voltage stabilizing circuit of controlled battery feed circuit.Current rectifying and wave filtering circuit is made up of rectifier bridge D1, capacitor C 1, C2; Voltage stabilizing circuit is made up of voltage stabilizing chip U1, voltage-stabiliser tube D2, inductance L 1, capacitor C 3-C6, diode D3; Controlled battery feed circuit is made up of battery BT, resistance R 1, R2, optocoupler U2, external drive signaling switch SW1, triode Q1, relay J 1, diode D4; The input through transformer transformation AC power through rectifier bridge D1 rectification, electrochemical capacitor C1, C2 filtering output to voltage stabilizing circuit, through voltage stabilizing chip U1 voltage stabilizing, again through the further voltage stabilizing of voltage-stabiliser tube D2, after inductance L 1, capacitor C 3-C6 filtering, obtain stable voltage, feed system after diode D3 step-down outputs to controlled battery feed circuit simultaneously, and this moment, the MCU signal was a low level, optocoupler U2 work, triode Q1 conducting, battery BT is given in relay J 1 adhesive charging.When ac input end did not have power supply, the system MCU signal was a high level, deenergization, system power supply disconnects, battery BT is consumed power not, have only when external drive signaling switch SW1 is closed, system just electric work, thereby give the alarm.
Operation principle of the present utility model is:
AC power after the transformer step-down (16.5v) is carried out full-wave rectification through rectifier bridge, obtains the DC power supply of 23V then through capacitor C 1, C2 capacitor filtering.The 23V DC power supply is depressured to direct current 15V through voltage stabilizing chip U1 again, again through the further voltage stabilizing of voltage-stabiliser tube D2, inductance L 1, capacitor C 3-C6 filtering, diode D3 is unidirectional conducting diode, prevent that electric current from pouring in down a chimney, direct current through diode D3 output is pressed with two use, and a function is to charge to 12V lead acid accumulator BT; Also for system provides power supply, controlled battery feed circuit is made of relay J 1, triode Q1, optocoupler U2, diode D4, current-limiting resistance R1, R2.When external communication 16.5V normal power supply, the system MCU signal is by the 2nd pin input low level of optocoupler U2,3, the 4 pin conductings of optocoupler U2, drive triode Q1, thereby drive relay J 1, make the normally opened contact of J1 become closure, lead acid accumulator can be recharged like this; When the AC16.5V AC power disappears, the MCU signal becomes low level, relay J 1 disconnects, system is by the power supply of the lead acid accumulator of 12V, when the conducting of external drive signaling switch, and system's storage battery power supply of getting back, system can work on, when the disconnection of external start signal switch, storage battery stops the power supply to system, thereby reaches the purpose of economize on electricity.
