摘要:

在主单片机80C196KC的控制下，应用HIP9011爆震信号处理专用芯片和ATmega16L微处理器，实现了对基于机体振动法的非共振型压电式爆震传感器输出的汽油机爆震信号的处理，研究了基于HIP9011的汽油机爆震判别方法，设计了爆震判定程序，研究证明采用HIP9011芯片对爆震信号进行处理从而对爆震进行控制是可行的，能够满足现代汽油机点火和发动机管理系统对爆震检测的要求。

Abstract:

A common used non-resonance piezoelectric knock sensor based on body vibration principle was studied. The knocking signal was processed using knocking signal processing chip HIP9011 and ATmega16L microprocessor under the control of main singlechip 80C196KC. Moreover, a knocking judgment method was studied based on HIP9011 and knocking judgment procedure was designed. The results prove that processing knocking signal using HIP9011 and further actualizing knocking feedback control is feasible. The method can satisfy the demand of engine ignition and management system to the knocking check.  
