【Abstract】 In view of the less research on the shock wave overpressure test for human thoracic cavity, a cylindrical target simulating human thoracic cavity is designed, a shock wave overpressure storage and test system embedded in the thoracic cavity target is established, and the real-time extraction technology of shock wave characteristic parameters is studied. The test system is controlled by FPGA(field-programmable gate array), and the ICP-type piezoelectric pressure sensor is adopted. On the basis of the basic functions of the existing shockwave storage and test system, the real-time extraction of shockwave characteristic parameters is realized in combination with the WiFi technology. The system function testing in the laboratory environment and the system function validation in the field test environment are carried out. The results show that the test system can completely record the data curve of the shock wave pressure load on the thoracic target and extract the shock wave characteristic parameters in real time, which provides a new means for the study of the destruction mechanism of the human thoracic cavity under the shock wave pressure load.更多还原
