3、使之在最佳狀態(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(cè)系統(tǒng)和監(jiān)控分站，且都以PIC單片機(jī)為核心構(gòu)成。瓦斯檢測(cè)系統(tǒng)采用新型載體催化元件作為檢測(cè)傳感器，具有高精度，高可靠性，功能強(qiáng)大，功耗低的特點(diǎn)。監(jiān)控分站既可以采集各種現(xiàn)場(chǎng)信號(hào)，進(jìn)行判斷處理，又可將數(shù)據(jù)傳送至地面的監(jiān)控主機(jī)，由地面的監(jiān)控主機(jī)也進(jìn)行控制，實(shí)現(xiàn)對(duì)對(duì)象的“雙重控制”，增加了整個(gè)系統(tǒng)的可靠性。關(guān)鍵詞 關(guān)鍵詞：瓦斯監(jiān)控；新型載體催化元件；監(jiān)控分站；PIC 單片機(jī)。Abstrac

4、tThe 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.

5、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

6、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

7、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 detecti

8、on 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

9、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
