Warehouse Automatic Fire A1arm System Based On MCU

Warehouse is a important place of centralism storage enterprise material,the security of warehouse management is priority target. But warehouse security's threat mainly comes from the artificial destruction and the warehouse commodity change of environment or commodity's from changes, in which warehouse's biggest security threat come from fire of humanself arouse. The event of fire, will cause serious economic losses, may also result in casualties with very serious consequences. Fire is acombustion process of loss control of human and causing some damage in time and space. Fire is the most common disaster that harm to human life and property anddirect impact on econmoic development and social stability. Fire's hidden danger greatly increased along with rapid economic development,building and warehouse increasing. It's one of the most disaster that have high imperfection and destructiveness in our country.This paper is based on the singlechip's multisensor 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 ATmega16 AVR 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, communications and other functions.2. Fire information detected by the smoke sensor NIS-09C and used in conjunction with temperature sensor DS18B20, by nonlinear and linear time series analysis algorithms to predict the on-site fire information whether the alarm value.3. Automatic fire warning system and external communications with the wireless communication, the TC35i wireless communications using GSM module for wireless communication circuit design, TC35i wireless communication module with anti-interference ability, low power consumption. When the main chip deal with the scene information,if this information reached the fire alarm value,the host controller will send the SMS to notify the relevant staff and sound and light alarm on-site.The purpose of this paper is to develop a low cost, simple structure, easy to use and can find timely and effective fire prevention omission, false automatic fire warning system.
