摘要
我们将Proteus仿真软件引入"感测技术"的课程设计,实现了压电式加速度传感器信号调理电路、信号采集电路以及显示电路的设计。我们通过仿真分析了电荷放大器与电压放大器的增益特性差异,高低通滤波器的幅频特性,得出了与理论分析相一致的结果。利用Proteus仿真软件进行课程设计,可以弥补元器件参数选择的不足,增加设计方案的可行性论证,减少设计和调试时间,具有较高的实用价值。
The design of signal amplification circuit for piezoelectric acceleration transducer, data collected modular circuits and LCD display circuit can be simulated with Proteus software in the curriculum project of Sensor and Measurement Technique. This paper analyses the gain characteristic difference between charge amplifier and voltage amplifier and it can shows the graphical chart of amplitude frequency response characteristics in the high-pass filter and low band filter by means of simulation. The results of simulation with Proteus software correspond to theoretical analysis. There are many good features by means of using Proteus software in the curriculum project of Sensor and Measurement Technique, such as covering the shortage of component parameter selection, feasibility assessment, short-time debug and so on for students, so it will be used extensively in the future.
