Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, a kind of passive automatic power cut off alarm device, comprise insurance RD, transformer B, bridge rectifier filtering D, triode Q, first filter capacitor C1, 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 first end of three-terminal regulator block W, one end of first filter capacitor C1 connects, the described first filter capacitor C1 other end respectively with bridge rectifier filtering, three-terminal regulator block W second end connects, described second filter capacitor C2 is connected between second end of three-terminal regulator block W and the 3rd end, the protection diode D5 of relay J, relay J, second filter capacitor C2 is in parallel, 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, 1 pin positive voltage energization input of described music integrated block IC (HFC9300) is connected with relay J normally closed contact one end, 2 foot control signal input parts are connected with the other end of relay J normally closed contact, 3 pin shared grounding ends are connected with the other end of relay J, 4 pin audio outputs are connected with triode Q first end, described triode Q second end respectively with 3 pin of music integrated block IC, large bulk capacitance C3 one end connects, 3rd end of described triode Q is connected with loudspeaker RL one end, the described loudspeaker RL other end respectively with 1 pin positive voltage energization input of music integrated block IC (HFC9300), the large bulk capacitance C3 other end connects.
As shown in Figure 1, principle of work of the present invention is as follows: do not having outage, input power is input to power transformer B through insurance RD, the low tension that transformer B exports is through the filtering of integral expression bridge stream, again through the first filter capacitor C1, three-terminal regulator block W, the second filter capacitor C2 filtering voltage regulation, become stable DC voltage.Relay J obtains operating voltage and controls normally closed contact disconnection, and the voltage at the second filter capacitor C2 two ends supplies music integrated block IC (HFC9300), triode Q, loudspeaker RL power supply through diode D6, charges to electric capacity C3 simultaneously.1 pin of music integrated block IC (HFC9300) is positive voltage energization input, and 2 pin are control signal input end, and 3 pin are shared grounding end, and 4 pin are audio output.Now because the normally closed contact of relay J continues out, 2 pin of music integrated block IC (HFC9300) can not get positive voltage input, IC(HFC9300) 4 pin just do not have audio frequency to export, loudspeaker RL would not send the sound.
If had a power failure suddenly, the present invention just inputs without power supply, the capacity of the first filter capacitor C1 and the second filtering C2 is very little, first filter capacitor C1 and the second filter capacitor C2 is by the coil discharge of relay J, electricity disappears soon, and relay J loses operating voltage normally closed contact and recovers conducting.The voltage now large bulk capacitance C3 filled starts to supply music integrated block IC (HFC9300), triode Q, loudspeaker RL power supply.Due to the unilateral conduction of charging diode D6, the voltage on large bulk capacitance C3 can not be powered to relay J by charging diode D6.Large bulk capacitance C3 positive pole is by the normally closed contact of relay J, 2 pin positive voltages of supply music integrated block IC (HFC9300), 4 pin of music integrated block IC (HFC9300) with regard to output audio signal to the base stage of triode Q, amplify through triode Q, the collector of Q exports audio frequency to loudspeaker RL, and loudspeaker RL sends the sound.Post operator on duty just obtains the information of power failure immediately, takes corresponding treatment measures at once.
