传统电工电子学实验以理论验证为主,缺乏综合性和应用性,文章提出了基于薄膜压力信号处理的综合实验设计,针对分布式薄膜压力传感器的阵列可变电阻存在交叉耦合的现象,设计输入和输出电路,依次得到受力下阵列中每一个电阻的单点压降,满足不同应用需求。该实验将电工电子学课程中丰富的理论知识综合运用,具有创新性和趣味性。 Traditional electrical and electronic experiments to verify the theoretical basis, the lack of comprehensive and applicability, the paper proposed a comprehensive experimental design based on the film pressure signal processing, the array of variable resistance for the distributed film pressure sensor cross-coupling phenomenon exists, the design input And the output circuit, in order to get a single point pressure drop of each resistor in the array under stress, to meet different application requirements. This experiment combines the rich theoretical knowledge in the course of electrotechnics and electronics with innovativeness and fun.
