Initial Study Of Measure And Control System For Combustion Driven Chemical Laser

Measure and control system is one of the most important proportion to insure the proper function of Chemical Laser. This paper has initially studied the measure and control system which is used on the Combustion Driven Continuous Wave Chemical Laser, using the technology of virtual instrument(VI). The main content is following:At first, the whole configuration of measure and control system on Combustion Driven Chemical Laser has been programmed. It has been divided into five part, including the inspection of pressure and single gas path, the start and operation control of laser, the measurement of air pressure and flow mass, safety alarm, data processing.Secondly, the dissertation introduces the operating principle of the measure and control system in detail. Combined with virtual instrument technology, the paper gives the design and program of the whole hardware system, introduces the function of every part, especially exploited the multifunction of Date Acquisition(DAQ) Card. The author also designs the signal process circuit, has a preliminary study on the way of anti-jamming for the signal in circuit.Thirdly, it is given the method of software make-up with LabVIEW of the system. In the paper, the author introduces the way of Date Acquisition in detail, the design and optimization of the code, figures out how to synchronize multi-board DAQ card, tries to control the digital signal out with multifunction DAQ Card.Fourthly, in the paper the author optimized the design of software. Based on the research of digital filtering, the paper presents a new digital filtering method, which can effectively and quickly do real time signal filtering.At last, the result of the experiment indicates that the system's functions catch the requirement of the devise and applications. Comparing with the traditional method, the new system strikingly reduces manual work and increases the test and processing efficiency.
