Abstract
Along with society's unceasing progress, people to own property safety protection is more and more attention. Therefore, appeared on the market a lot of electronic anti-theft products, people used to install in the dormitory, multi-story buildings, warehouses, and to protect their life and property safety in the family.
This design mainly introduces the triggered by dc regulated power supply, control circuit, the LED indicator circuit and sound alarm circuit consisting of a central control anti-theft alarm circuit, realizing when a circuit when there is abnormal, the circuit of light emitting diode light, diode conduction, relay and, alarm functions.
This article mainly introduces the related knowledge and debugging the production process, the design of simple circuit, easy manufacture and low cost. If mistakes are found, or is incorrect, please the teacher can give correct me.
Keywords: Regulated power supply trigger control circuit The LED indicator circuit Sound alarm circuit
