摘　　要：针对传统力传感器只能以模拟量形式输出而在数据处理时又往往需转换为数字量的问题,基于力敏Z元件的频率输出特性原理,辅以单片机处理电路,提出了一种数字形式输出的力传感器的设计方法,经实际应用表明,无需A/D转换便可以直接被计算机拾取,具有使用方便、抗干扰能力强的特点,从而为力参量的测量提供了另一种手段。Considering the problem that force sensors now can only put out analogue value, but it is always needed to convert to the digital value before it can be dealt with, a kind of force sensor is designed which is based on Z-elements' property of output frequency and circuit of SCM. Through practice using, it shows the value can be directly used by computer without the convertion of A/D and has the characters of using convenient and better anti-jamming. So it presents another method of measuring force parameter.
