"Three Preventions" System Design Based On Single-Chip Microcomputer (SCM) Control

With the rapid development of social economy, Science and technology level are increasingly improving, especially accelerated pace of life, People demand for fireproof, anti-theft and anti-gas equipment is greatly increased, and for theft, fire and other accident monitoring and alarm system requirements are also higher. In the research of this thesis is based on AT89S52 SCM as the core of the fireproof and anti-theft alarm system, not only can call the police, but also can display the alarm information category. This system selects the smoke sensor, gas sensor, pyroelectric infrared sensor for detecting element, and uses multi-sensor information fusion technology designed to be used for fire and theft alarm in small-scale agricultural production, etc. This design is reasonable, the product performance and reliable, and can replace some expensive product.
