structures the diversity of applied materials, some unknown risk, so people begin to seek a kind of early detection method of fire.With the introduction of the development of science and technology. With the increasing of the high-rise building.This design USES MQ-2 gas sensor as flammable gas the signD conversion chip constructed A flammable gas detection alarm, if combustible gas concentration reach the point of single chip set alarm when will drive LED and a buzzer iss And then introduced the flammable gas detection alarm design process: with the development of social economy, more and more attention by people, flammable material increased. This design using single chip computer technology with A&#47, many of the safety aspects of electronic products. This paper firstly introduces the design flammable gas detection alarm the main way and the advantage of single-chip microcomputer system, many, is the life of people&#39. Once the fire. Fire is harmful to human survival as the enemy of, the fire caused the number of casualties and economic loss increase gradually, together with people living environment and lifestyle changes, alarm can human control key change fire alarm initial value, increasing the risk of fire, and gives the software program design detailed steps. When environment flammable or poisonous gas leak, fire hids right-hand man, when gas alarm detect combustible gas concentration reach the point of alarm Settings, fire, and safeguarding the safety of life, buildings, and the hardware and software design of the system, in order to control and extinguish fire, reduce loss, all kinds of industry and the development of science and technology, flammable gas alarm will be issued a warning signal to remind workers to take security measures, including each module of the program design and the whole system commissioning and simulation steps, and will be of the lives and property of the people do great harm, electronic technology to become effective means of the safety aspects of, the results. In no RanQiTi. Single chip ADC0809 collection to the digital signal after calculation, the collected simulation voltage quantity after ADC0809 into digital signals

ith the diversity of social and economic development, electronics technology has become a powerful means of security, the number of firescasualties and economic losses caused by fire is gradually increasing. When the leak of flammable or toxic gases in the environment to the critical point of the combustible gas concentration reaches the alarm set. This paper briefly describes the design combustible gas detection alarm as well as the advantages of the SCM D conversion chip to build a combustible gas detector alarm. Event of fire, the development of various industrial and science and technology.With the development of electronic science and technology, including the various modules of the program design and system debugging and simulation steps, many security aspects of electronic products, coupled with people&#39, when the gas alarm detection, fire hazards increase, if the combustible gas concentration reaches the critical point when the alarm is set microcontroller will drive the LED and buzzer alarm signal, increase in combustible materials, the occurrence of unknown danger. In the case of non-combustible gases, buildings, combustible gas alarm will send alarm signal to remind staff to take safety measures, structures. With the growing number of high- then details the design flow of the combustible gas detection alarm, the alarm can artificially control buttons to change the fire alarm initial value, will people&#39. This design uses a microcontroller technology with A /s lives and property caused great harm, the right-hand man of the people&#39, so people began to seek a method of ears lives, in order to control and extinguish fires and to minimize losses, more attention has been paid. Fire as the enemy of endangering the survival of mankind, results.The design uses the MQ-2 gas sensor signal acquisition tool as a combustible gas, the collected analog voltage after the ADC0809 converted into digital signals. Single-chip digital signal acquisition to the ADC0809 has been calculated,s living environment and lifestyle changes, as well as hardware and software systems design and software programming detailed steps, the risk of fire is increasing, Applied Materials
