The control function of the electric circuit is plished by a microcontroller. The whole electric circuit of alarm is posed by four parts: data acquisition module, data enlarge module, A/D module and microcontroller. The technological process of the alarm is as follows: The analogue signals are collected by two kinds of transducers, and then the signals are transmitted to the ADC after enlargement. The data signals are transmitted by ADC to the 8051 microcontroller. The judgment of the buzzer alarm is made after the fata processed by 8051. Main work in this dissertation is :pleting the choice of the machines, the design of the connection and the development of the procedure for data processing, realizing the autom atically monitor ＣＯ density. As a result it can prevent fatal accidents. It designed with visual Basci and 8051 microcontroller ,and the design of 東華理工大學(xué)畢業(yè)設(shè)計(jì)（論文） 有害氣體檢測(cè)與報(bào)警系統(tǒng)設(shè)計(jì) 李迪 4 hardware , software, data base and distance controll of this system are put forward. The annunciator can be widely used in fam ilies and panies. The occurrence rates of the accidents such as poisoning fire, burst, etc are deeply reduced. Tt has an important and pratical value.
