| Presently, along with the economical development, people's life improves day by day, the people take seriously more and more to the family personal safety and property, and has adopted many measure protection family security. The former procedure is the installment burglar-proof door, the security net, but also exists obstructs artisticly, does not meet the fire protection requirement, not to be able to prevent unprincipled person's shortcomings effectively and so on invasion.At present, in the market exists variously lives at An Fang, the fire protection security alarm system, but they are mostly by part constitutions and so on traditional sensor and program control installment, the system rate of false alarm is high, the reliability to be quite bad.In view of this, this topic is for the purpose of designing one kind of low rate of false alarm, the reliable high intelligence housing safety and protection system. Its collection fire protection security function in a body, may realize the automatic detection and the dial telephone digit dialing warning. This design take MCS-51 series monolithic integrated circuit AT89S51 as a core, unifies the periphery wireless code reception electric circuit, the digital pronunciation recording and sending out electric circuit, the speech circuit, as well as the other periphery auxiliary circuit, constituted section of high performance intelligent wireless peaceful against alarm apparatus. And, the infrared acquisition aid and the microwave detector realize rob the sentiment warning; As the compound expression fire detector which a body constitutes may complete the fire warning take the temperature detector and the optical detector of fire smoke collection. This multi-sensor's application has realized the low rate of false alarm, strengthened system's reliability. Moreover this system separately has carried on the antijamming design from the hardware and the software two aspects, sharpened system's antijamming ability. |
