Abstract
On the basis of full analysis of gas detection instruments, the use of DSP and ultrasonic technology to design a new type of gas concentration detection system. DSP is the core of the whole system, mainly complete the DDS chip sequence control, special A/D sampling control and external FLAS H and SDRAM memory chip control, and to communicate with PC through serial port. Discussed the principle of ultrasound detection of gas concentration, as well as within the DSP to realize time domain signal autocorrelation operation, to improve the signal-to-noise ratio. Hardware structure diagram and software design of the system are given with the block diagram, the experiment proved that the system well meet the requirements of the gas concentration detection, can be used in a variety of gas detection.
