摘　　要：一直以来,传感器实验教学普遍采用实验室的教学方式,高度依赖实验室和固定的实验电路。虽然实验室教学有诸多优点,但是实验教学过于依赖实验室,缺乏灵活性。Multisim是一款专业的电路仿真软件,主要用于模拟电路和数字电路仿真。目前,运用Multisim软件对传感器实验电路进行仿真并未被广泛使用,Multisim软件的引入可以使传感器实验教学更加灵活、便捷。通过应变式电阻传感器和差动变压器电路的仿真,验证了传感器原理和相应测量电路的正确性,证明了基于Multisim的传感器实验教学是一种行之有效的教学方式,仿真实验可以作为传感器实验室教学方式的补充。在不具备传感器实验室的院校,传感器仿真实验可以作为首选的实验教学方式。同时,仿真实验也可以增加学生对传感器原理的理解。For a long time,the sensor experiment teaching generally adopts the laboratory teaching method,relying on the laboratory and the fixed experimental circuit.Although the laboratory teaching has many advantages,the experimental teaching is too dependent on the laboratory,lack of flexibility.Multisim is a professional circuit simulation software,mainly used for analog and digital circuit simulation.Multisim is not widely used in the design and simulation of sensor experimental circuit,and the introduction of Multisim software will make sensor experiment teaching more flexible and convenient.Through the simulation experiment of strain type resistance sensor and differential transformer circuit,the correctness of sensor principle and measurement circuit is verified,and the sensor experiment teaching based on Multisim is an effective teaching method.The sensor simulation experiment based on Multisim can be used as a supplement to the laboratory teaching.In colleges and universities without sensor laboratory,sensor simulation experiment can be regarded as the preferred experimental teaching method.At the same time,the simulation experiment also increases students'understanding of sensor principle.
