【Abstract】 This paper is about the designing ideology, functions of various parts, system software-controlled structure and the purpose of the microcomputer controlled system used for hunting, selecting and data handling for the working series on lines of CO2 frequency-selecting laser in device. The system can guarantee the accuracy and high speed of the working series of lines’ detecting and transmitting of the CO2 laser when BAIL device measurer atmosphere pollution on real time. It can also ensure better results by reducing errors caused by atmosphere turbulence.更多还原
