基于单片机的火灾预警系统设计 Abstract With the development of economic,many occasions need to prevent fires and install different accuracy of fire alarm systems ,because the event of fire, will cause serious economic losses, may also result in casualties with very serious consequences. Fire is a combustion process of loss control of human and causing some damage in time and space. Fire is the most common disaster that is harm to human life and property and can cause a big effect on economic development and social stability. Fire’s hidden danger greatly increased along with rapid economic development, building and warehouse increasing. It’s one of the disaster that happened all the time and destructiveness in our country. This paper is based on the single chip’s multisensory fire detection system, this system has the collection site information, and information analysis and forecasting ,the results passed to the relevant personnel and display fire information function, and can be carried out in the field of fire alarm sound and light features. This paper to in-depth research for warning system for the automatic fire situation at home and abroad conducted. It’s comprehensive exposition of the automatic fire warning system hardware and software components of the specific programs. Following is a major work to do this: 1. The main chip of the controller of automatic fire warning system is used in the United States ATMEL Corporation AT89C51 microcontroller series, the chip has a low cost ,high speed, low power consumption.The main chip analyze the data of the sensor’s data, and then sent to the LCD. Early warning system designed with a higher cost performance and has operations personnel management, probe management, pre-alarm, fire processing and other functions. 2. Fire information detected by the smoke sensor MQ-2 and used in conjunction with temperature sensor DS18B20,by nonlinear and linear time series analysis algorithms to predict the on-s
