Abstract: In some of testing system ,as an non‐electricity acquisition device ,acquisition equipment with high internal resistance and is subject to the charge of am signal is little ,charge of the easy back‐end secondary equipment impedance wasted ,leading to a relatively poor acquisition precision .In order to solve the above problems ,this article designed a charge signal conditioning with high precision ,high stability and strong anti‐interference performance .Compared with the traditional charge signal conversion equipment ,the charge signal conditioning in this paper has a high precision , small error and small volume ,it is more suitable for the application in the complex airborne environment .Through constructing test environment test shows this method is effective and feasible ,this method can be applied in other non‐electricity piezoelectric sensor data acquisition occasion .
