Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1; a kind of passive outage autoalarm; comprise insurance RD; transformer B; bridge rectifier filtering D; triode Q; the first filter capacitor C1; the second filter capacitor C2; large bulk capacitance C3; regulator block W; music integrated block IC (HFC9300); loudspeaker RL; described transformer B input end is that power input P1 connects with insurance RD; described transformer B output terminal through bridge rectifier filtering respectively with the end of three-terminal regulator block W; the end of the first filter capacitor C1 connects; the described first filter capacitor C1 other end respectively with bridge rectifier filtering; the three-terminal regulator block W other end connects; the described second filter capacitor C2 is connected between the other end and all the other ends of three-terminal regulator block W; the protection diode D5 of described relay J; relay J; the second filter capacitor C2 parallel connection; described charging diode D6 one end is connected with relay J one end; the other end is connected with relay J normally closed contact one end; described music integrated block IC (HFC9300) 1 pin links to each other with relay J normally closed contact one end; 2 pin link to each other with the other end of relay J normally closed contact; 3 pin link to each other with the other end of relay J; 4 pin triode Q, one end links to each other; the described triode Q other end respectively with music integrated block IC (HFC9300) 3 pin; large bulk capacitance C3 one end connects; all the other ends of described triode Q are connected with electric bell RL one end, the described electric bell RL other end respectively with 1 pin of music integrated block IC (HFC9300); the large bulk capacitance C3 other end connects.1 pin of described music integrated block IC (HFC9300) is positive voltage power supply input end, and 2 pin are the control signal input end, and 3 pin are the shared grounding end, and 4 pin are audio output.
As shown in Figure 1, principle of work of the present utility model is as follows: do not having outage, the input power supply is input to power transformer B through insurance RD, the low tension of transformer B output is through the filtering of integral expression bridge stream, through the first filter capacitor C1, three-terminal regulator block W, the second filter capacitor C2 filtering voltage regulation, become DC voltage stably again.Relay J obtains operating voltage control normally closed contact and disconnects, and the voltage at the second filter capacitor C2 two ends is supplied with music integrated block IC, triode Q, loudspeaker RL power supply through diode D6, simultaneously to capacitor C 3 chargings.1 pin of music integrated block IC (HFC9300) is positive voltage power supply input end, and 2 pin are the control signal input end, and 3 pin are the shared grounding end, and 4 pin are audio output.This moment, loudspeaker RL just can not send the sound because the normally closed contact of relay J continues out, and 2 pin of music integrated block IC (HFC9300) can not get the positive voltage input, and 4 pin of IC just do not have audio frequency output.
If have a power failure suddenly, the utility model has not just had the power supply input, the capacity of the first filter capacitor C1 and the second filtering C2 is very little, the first filter capacitor C1 and the second filter capacitor C2 are by the coil discharge of relay J, electric weight has disappeared soon, and relay J has lost the operating voltage normally closed contact and recovered conducting.The voltage that fill on the large bulk capacitance C3 this moment begins to supply with music integrated block IC (HFC9300), triode Q, loudspeaker RL power supply.Because the unilateral conduction of charging diode D6, the voltage on the large bulk capacitance C3 can not powered to relay J by charging diode D6.Large bulk capacitance C3 positive pole is by the normally closed contact of relay J, supply with 2 pin positive voltages of music integrated block IC (HFC9300), 4 pin of music integrated block IC (HFC9300) are with regard to the base stage of output audio signal to triode Q, amplify through triode Q, the collector of Q exports audio frequency to loudspeaker RL, and loudspeaker RL sends the sound.The post operator on duty has just obtained the information that has a power failure immediately, takes corresponding treatment measures at once.
