摘要 現(xiàn)階段煤礦安全問題已經(jīng)成為全社會關(guān)注的焦點，成為關(guān)系到人民生命財產(chǎn)，甚至影響建立和諧社會的重大問題。研發(fā)出高質(zhì)量、高性能、高可靠性、低成本的煤礦瓦斯監(jiān)控系統(tǒng)無疑對解決這一重大問題有很大幫助。本文提出了一種瓦斯監(jiān)控系統(tǒng)的整體解決方案，該系統(tǒng)集數(shù)據(jù)采集，分析處理狀態(tài)下工作。瓦斯監(jiān)控系統(tǒng)主要有兩部分構(gòu)成，瓦斯檢測系統(tǒng)和監(jiān)控分站，且都以PIC單片機為核心構(gòu)成。瓦斯檢測系統(tǒng)采用新型載體催化元件作為檢測傳感器，具有高精，控制及數(shù)據(jù)通訊等功能于一體，能有效地對瓦斯抽放狀態(tài)進行連續(xù)跟蹤監(jiān)測和實時調(diào)控，使之在最佳度，高可靠性，功能強大，功耗低的特點。監(jiān)控分站既可以采集各種現(xiàn)場信號，進行判斷處理，又可將數(shù)據(jù)傳送至地面的監(jiān)控主機，由地面的監(jiān)控主機也進行控制，實現(xiàn)對對象的“雙重控制”，增加了整個系統(tǒng)的可靠性。

Abstract
The security problem of coal mines has been a focus that all the society is looking for it now. It has been an important problem relating to the property and life of people even influencing building harmonious society. So the research on the Monitor and Control System of Gas with high quality ,high capability, high reliability and low cost will help to resolve this important problem deeply.In this paper, a gas monitoring system of the overall solution is raised. This design scheme includes collection,analysis and treatment of data function, control function and data communication function. It can continuously monitor gas concentration and control gas deflation to make it work in the best condition.The Monitor and Control System of Gas can be divided into two main part, the gas detection system and control unit ,and they are all based on MCU of PIC. In the gas detection system, a new carrier catalytic components is used for the detection sensors,and it can satisfy the user demand of high precision, high reliability,multi function and low power demand.The monitor and control unit can gather ,process, and transmit the data of gas to the main computer. The main computer on the ground also control the system to achieve the object of "dual control",and it can increase the reliability of the entire system.
Key words: gas monitor and control; new carrier catalytic components; the monitor and control unit;mcu of pic.
