采用AVR系列ATmega8單片機(jī)設(shè)計(jì)并研制了紫外火焰探測(cè)器響應(yīng)時(shí)間測(cè)試系統(tǒng)，介紹了該系統(tǒng)的結(jié)構(gòu)和工作原理，論述了系統(tǒng)中高能自動(dòng)點(diǎn)火裝置與時(shí)間測(cè)試儀的同步特性，研究并測(cè)試了不同型號(hào)火焰探測(cè)器的響應(yīng)時(shí)間。樣機(jī)運(yùn)行的測(cè)試結(jié)果表明：該響應(yīng)時(shí)間測(cè)試系統(tǒng)的設(shè)計(jì)是成功的，消除了現(xiàn)行火焰探測(cè)器響應(yīng)時(shí)間測(cè)試方法中存在的點(diǎn)火與計(jì)時(shí)不同步而引起的測(cè)量誤差.

The AVR series mega8 singlechip is used to develop the response time test system of ultraviolet fire detector. This paper presents the components and working principle of the system, and emphasizes the synchronization characteristics of the auto ignition equipment and response time test meter of the system. The response time of different ultraviolet fire detectors was tested by the system. The results show that the design of the response time test system of fire detector is feasible and it avoids the measuring error caused by the asynchronous operation in traditional response time test method.
