【Abstract】 The "man-machine-environment" feature has become an important performance indicator of weapon equipment,and the test of the gas concentration change process in the weapon test environment will become more and more important. Therefore,a man-machine ambient gas test system is designed and applied in weapon tests,which can automatically record the changes of various gas concentrations during the test. Through the combination of electrochemical sensing technology and storage testing technology,4-channel gas testing is realized with a sampling rate of 48 Sps and a storage capacity of1 GB.The inverse modeling method of the PSO algorithm is used to establish a 5th-order dynamic compensation filter to dynamically compensate the system. It is verified by experiments that the dynamic response time of the system after compensation is reduced from 15.25 s to 3.42 s. Combined with the dynamic compensation link,the test system has reliability and real-time performance,and the dynamic response time is increased by 77.5%,which meets the requirements of the rapid change of the human-machine environment gas in the weapon test.更多还原
