Description
Technical field:
The present invention relates to a kind of alarm technique.
Background technology:
Existing warning circuit, the duty that the multiple electronic device of forming circuit all need to be in awaiting orders, therefore, energy consumption is high, and some warning circuit is by reducing the energy consumption that reduces of measuring ability, but reduced again the alert capability of warning circuit.
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of warning circuit of multi-functional, low energy consumption.
The present invention realizes like this, comprise pressure switch, thin plain conductor, CD4011BCN integrated package, on-off circuit, the relay of gauge tap K1 folding, buzzer, power supply is successively by K switch 1, ground connection after buzzer, power supply is successively by high resistance measurement R5, thin plain conductor, low resistance resistance R 4 ground connection, the pin 1 of CD4011BCN integrated package, pin 2 is connected to high resistance measurement R5 by resistance R 6, between thin plain conductor, the pin 3 of CD4011BCN integrated package is connected to by resistance R 8 on the pin 8 of CD4011BCN integrated package, the pin 9 of CD4011BCN integrated package is by resistance R 2, capacitor C 1 ground connection, the pin 10 of CD4011BCN integrated package and the pin 12 of CD4011BCN integrated package, pin 13 is connected, the pin 11 of CD4011BCN integrated package is connected to the trigger end of on-off circuit by resistance R 1, the pressure switch of often opening without pressure is attempted by high resistance measurement R5.
When work, the pin 3 of CD4011BCN integrated package is low level, not conducting of on-off circuit, relay, buzzer all do not power on, as at least one situation in pressure switch closed, thin plain conductor disconnection under pressure occurs, the pin 3 of CD4011BCN integrated package is exported high level so, on-off circuit conducting, the actuating of relay makes K1 closure, thus trigger alarm. Delay circuit R2, C1 ensure on-off circuit conducting 100s left and right.
Here, resistance R 6 is serially connected with by resistance R 5, capacitor C 4 low-pass filter circuit that connects, by and the resistance R 7 connecing, low-pass filter circuit one end ground connection that capacitor C 3 forms, one end is connected on the pin 3 of CD4011BCN integrated package, and two low-pass filter circuits can suppress startup and shutdown makes the impact of voltage jump on circuit working.
Because high resistance measurement R5(resistance reaches 12M, and the pin 3 of CD4011BCN integrated package is low level under normality, like this, the electric current of whole circuit is little, energy consumption is very low, adopts pressure switch, thin plain conductor can ensure that again warning circuit has the Trigger Function under various states, therefore, compared with the prior art the present invention, has advantages of multi-functional, low energy consumption.
