《传感器与自动化仪表》课程改革的探索

Discussion about the Course of "Sensor and Automation Instrumentation"

信号处理技术在传感器技术和自动化仪表课程中占有重要的地位。在实际电路分析中,常遇到非理想的运放电路组成的信号测量和处理电路。但在模拟电路课程中,只对理想的运放电路进行了分析。该文对于非理想运放处理电路,提出采用自动控制理论中反馈系统方框图表示方法,分析非理想的运放电路,对现有教材的内容进行改进和补充,这样有利于加强学生的系统分析能力的培养,达到学以致用,融会贯通的目的。

The signal processing technology has played an important role in the course of sensor technology and automation instrumentation technology. In practical circuit, amplifier circuit which used in sensor and processing circuit, is not ideal amplifier circuit. In the course of analog circuit, the ideal amplifier circuit is only analyzed. In this paper, the analysis method of practice circuit based on the feedback analysis in con- trolling principle is introduced. The proposed method compensates the current textbook so that ability of system analysis for student is improved, and the subjective of understanding and application of the knowledge is realized.
