一种基于电容传感的乘员感应装置

A Passenger Response Installation Based on Electrical Condenser Transduction

安全气囊有时会造成不必要的浪费和对儿童的伤害。为解决这一问题，设计了一种新的基于电容传感原理的乘员感应装置，并介绍了电容传感器的构造及微小电容测量电路的设计。该装置克服了采用超声波原理和质量感应原理系统的不足，能够区分人体与非人体，为乘员感应系统的实用化提供了有效手段。静动态试验均证明了系统的可行性。

The fact that sometimes the safety air bag will cause unnecessary waste and injury to children inspires the authors to design a new passenger response installation based on the electrical condenser transduction function. Small condenser is adopted and its construction and measuring circuit are described. The installation can differentiate human body or not human body, which overcomes the shortage of other systems utilizing the supersonic or mass response function and provides an effective means to make the passenger response system practical. Static and dynamic tests have all proved the feasibility of the system.
