The Design Of Family Intelligent Fire-proof And Thelf-proof Alarm System Based On MCU

In recent years, with the rapid development of network communication technology, electronic technology and computer technology, the rapid socio-economic development and the rising of living standards, peoples'housing demands are becoming higher and higher.Not only a warm and comfort room, we also put forward higher requirements on its security and intelligence. The rapid development of modern electronic information and communication technology has provided a strong technical support for the study of the intelligent and safe houses.At present, the main way to install anti-theft is fitting security doors and security lock-based in china, but such equipment achieves the anti-theft goal by increasing the difficulty of breaking into house to the theft. This simple mechanical device, in the case of long time absence, of which the effect of anti-theft is not satisfactory, and it brings difficulties to people in the aspects of housing beauty and fire escape.Home Intelligent Fire Alarm System in this article,which is based on STC89C51 microcontroller and GSM communication module, is an intelligent wireless alarm system of easy operation and reliable running, and it use sensors and existing GSM network to achieve security monitoring required and alarm function which home requests, such as anti-fire, anti-theft, remote control. It adopts IR, temperature, door magnetic, gas and other real-time sensors to monitor home security and, if system is abnormal, it will promptly send short messages to inform the owner; using of GSM communication module solid state relay controlled by MCU, the owner can open the household appliances which you want to open outside, and when no one at home for long-term, it turns on the lights and simulates sound to the effect of a monk to let thieves give up stealing. This system makes the home owners understanding of all family information in a timely manner and allows families to obtain greater security.Now, cell phones have become necessities. The biggest innovation of this design is the introduction of SMS. It can automatically send alarm SMS when the home has an accident and remotely control the use of household appliances through the SMS. It brings great convenience and timeliness to people's life...
