传感器原理及应用课程项目教学与实践——以带有伸缩臂探测距离补偿的有毒有害气体巡检平台为例

传感器为构建智能化系统的重要组成部分,被应用于多个领域,具体包括环境监测、医疗诊断、航空航天、智能楼宇和家用电器等。以学生工作所需理论知识和实践经验为出发点,对传感器原理及应用这门学科实施项目教学,结合化工园区绿色安全发展的趋势,具体以油气管道的自动化巡检为例,紧跟最新的技术发展和技术应用。在项目教学的实践过程当中,使学生根据项目要求收集相关信息,设计解决方案;再针对学生拟解决问题的技术路线进行知识教授并对项目实施加以引导,突出理论可行性和实践操作性。学生对该学科有进一步的认识与理解。在掌握理论知识的前提下,培养学生的创新意识,提高学生科学素养,着重培养应用型人才所需的技能。项目教学法的实施不仅使学生对学科有系统的认识,强化关键知识点的学习,同时也提高学生的动手能力和创新能力。

As an important part of building intelligent system,sensor application technology is widely used in various fields of production and life,including environmental monitoring,medical diagnosis,aerospace,intelligent buildings and household appliances.Based on the theoretical knowledge and practical experience required by students'work,the project teaching of Sensor Principle and Application is implemented.Combined with the development trend of green safety in chemical industry park,the automatic inspection of oil and gas pipeline is taken as an example to keep up with the latest technology development and application.In the practice of project teaching,students can collect relevant information and design solutions according to the requirements of the project;Then,according to the students'technical route to solve the problem,the knowledge is taught and the project implementation is guided,highlighting the theoretical feasibility and practical operability.Students have a further understanding of the subject.On the premise of mastering the theoretical knowledge,it cultivates the students'innovative consciousness,improves the students'scientific literacy,and focuses on the skills required by the applied talents.The implementation of project teaching method not only makes students have a systematic understanding of the subject,but also strengthens the learning of key knowledge points;At the same time,it also improves the students'practical ability and innovation ability.
