Design Of Wireless Fire Remote Alarm For Intelligent Security System

With the modern household electricity consumption,the use of fire is increasing year by year,the frequency of home fires are also getting higher and higher.Wireless multi-function fire alarm is also widely used in various occasions.Disaster caused by the fire and the losses caused by it are also on the rise.Therefore,it is very important to develop a fire detector with good stability and high accuracy.In this paper,it has depth study in fire-induced factors and the occurrence of fire during the germination and early spatial environment changes.Through the simultaneous detection of temperature,CO concentration and smoke concentration of these three signals,we designed a comprehensive,multi-angle smart wireless fire alarm.The alarm mainly composed by the detection module,microcontroller module,wireless data transmission module and mobile phone client.The alarm simultaneously collects three kinds of signals of temperature,CO concentration and smoke concentration.It uses microprocessors to discriminate police intelligence based on fire information processing algorithms.It realizes the high reliability and real-time monitoring of fire information.This text chooses STM32 series one-chip computer as the microprocessor of the alarm.The temperature,CO concentration and smoke concentration were measured with a thermistor,a UL2075 sensor and an MQ-5 gas sensor,respectively.The sensor output signal is amplified.Then it is sent into the microprocessor chip A / D converted to digital signals.Microprocessor based on fire information processing algorithms to deal with the three detection signals to determine whether there is a fire.The system also based on this result to determine the alarm level.In the event of a fire,the system transmits alarm information to the Internet via Wi Fi module and wireless router.Users can read the alarm information in real time through the mobile APP,and find out the dangerous situation in time.This System achieved the fire alarm information Internet transmission through the Wi Fi technology.This method is not limited by the spatial distance.So that it solved the fire safety issues in unmanned space.Each sensor detection system reduces power consumption through the way of intermittent work.This approach enables the long-term continuity of the detection module.Compared with the traditional fire alarm,the system has low power consumption,low cost,high reliability and so on.
