三极管测量练习装置的开发

The Development of Triode Measuring Exercise Equipment

该文分析了三极管测量技能教学成效不佳的原因,开发了一个三极管测量练习装置。练习装置利用微控制器产生随机信号,随机选择管子类型,随机分配管脚到测试端口,随机设置故障,引导学生通过测量来判断管子类型、管脚排列和有无故障。实践表明,新装置能有效提高学生测量三极管的技能。

The paper analyzes the reason why the effect on the triode measurement skills teaching is poor, and what tries to develop a triode measuring exercise device. In order to guide students to determine what the triode type is,what＇s wong with pin array and whether there is malfunction by measurement, the exercise device generates random signals with micro controller, randomly selects a NPN or PNP triode, sets fault, and assigns pins to the test port. The study shows that the new equipment effectively improves the skills of students measuring triode.
