Alarm signal and the location code encoded by the encoder, through a wireless transmission work, long distance transmission. In the alarm terminals, the encoder will decode the received coded signal, and generates highlow signal transmitted to the single chip processor, to sound alarm signals, while the two digital display alarm for the position, when a number of way simultaneously alarm alarm when the position will exchange。 吉 林 農(nóng) 業(yè) 科 技 學(xué) 院 學(xué) 士 學(xué) 位 論 文 論 文 題 目： 熱釋紅外報(bào)警系統(tǒng) 年 級(jí) 專 業(yè)： 06級(jí) 電子信息科學(xué)與技術(shù) 學(xué) 生 姓 名： *** 學(xué) 號(hào)： *** 指 導(dǎo) 教 師： *** 評(píng) 閱 教 師： 完 成
