摘要:近年來，我國經(jīng)濟迅速發(fā)展，生產(chǎn)力不斷提高，電力作為經(jīng)濟的動力得到了迅速的發(fā)展。在發(fā)展過程中電廠無疑起著巨大作用，我國的發(fā)電廠越來越多，其中火電廠數(shù)量位居第一?；痣姀S是我國最主要的廢氣排放源，也是廢氣污染問題治理的重點。這些廢氣不僅對大氣有一定的污染，還給周圍居民的生活帶來不便，給他們的健康帶來很大的危害。因此，火電廠廢氣的治理刻不容緩。 本文介紹了一種基于單片機的廢氣傳感器檢測系統(tǒng)，該系統(tǒng)通過單片機驅(qū)動廢氣傳感器，從而對火電廠廢氣實行在線實時監(jiān)測和分析預測,防止由于廢氣濃度過高等各種原因造成的大氣環(huán)境污染。 經(jīng)處理分析后就能客觀、及時地反映火電廠廢氣排放狀況，從而達到環(huán)保生產(chǎn)的目的。 此外，硬件上，該系統(tǒng)由上位機和下位機兩大部分組成。本設計主要完成下位機部分，下位機采用與8051兼容的高性能、高速單片機—STC 12C5A60S2為控制器，它與安裝在煙囪的廢氣傳感器共同完成對火電廠廢氣中有害廢氣濃度的監(jiān)測。然后通過前置放大器將傳感器采集的數(shù)據(jù)放大后，送至ADC進行模數(shù)轉(zhuǎn)換。 關鍵詞：AT89C51；A/D轉(zhuǎn)換；廢氣；傳感器
Abstract:With china's rapid economic development and improving productivity, electric power, obtained as the economic power, has developed rapidly. Power plant plays a huge role in the development undoubtedly, China's power plants are increasing rapidly, and among them the thermal power plant occupies the biggest share. Thermal power plant is the major soot source, so as the focus of the soot pollution management. The dust in the atmosphere not only pollutes the atmosphere, but also brings inconvenience to the surrounding residents such as do great harm to their health, therefore, the management of thermal power plant admits of no delay . This paper introduces a kind of waste gas sensor detecting system based on single chip microcomputer, this system drives the waste gas sensors to get continuous online real-time monitoring, analysis, forecast on the waste gas through single chip microcomputer for fear of the atmospheric pollution caused by the high concentration of waste gas and other reasons. Objective and timely reflect on the emissions of the thermal power plant would be made after disposing and analyzing, so as to ensure the purpose of environmental producing. In addition, the system consists of a PC and an AT89C51 single chip. The design adopts the high performance microprocessor-STC12C5A60S2 compatible with 8051, as the controller, with the waste gas sensor installed in the chimney ,so as to detect the emissions of harmful gas concentration of the thermal power plant, and then the data collected from the sensors will be enlarged through the preamplifier, which would send to the ADC for A /D conversion.
