完成or in formerly in the related sensor aspect research subject foundation (specially was bui
lding class specialty) examines in the laboratory in the College of engineering the application.
First, this article proposed the fission type sensor laboratory bench's concept, and halves the writing style sensor laboratory bench the characteristic, the key technologies, the historical development, the research direction and the application prospect did said that simultaneously the sensor laboratory bench's situation has also made the analysis to the current market condition, proposed that manufacture laboratory bench necessity which tested in view of the College of engineering.
Next, the half writing style sensor laboratory bench has made the thorough analysis, mainly carries on from the following two aspects studies one is in the fission type sensor laboratory bench sensor principle; second, distributed body sensor laboratory bench major component's choice.
This sensor laboratory bench may widely apply in the College of engineering tests in the teaching, has the widespread application background and market development space.

在基础学科研究中,传感器具有突出的地位。现代科学技术的发展,进入了许多新领域:例如在宏观上要观察上千光年的茫茫宇宙,微观上要观察小到nm的粒子世界,纵向上要观察长达数十万年的天体演化,短到s的瞬间反应。此外,还出现了对深化物质认识、开拓新能源 、新材料等具有重要作用的各种极端技术研究,如超高温、超低温、超高压、超高真空、超强磁场、超弱磁场等等。显然,要获取大量人类感官无法直接获取的信息,没有相适应的传感器是不可能的 何希才,薛永毅:《传感器及其应用实例》,机械工业出版社,第8页。

作为现代工科大学实验教学的重要组成部分,传感器实验具有重要地位。本次毕业设计针对大学教学实验要求,以更好的帮助学生理解传感器原理,掌握其使用方法为目的设计实验台。该设计中大部分是工业结构,便于学生加强对书本知识的理解,并在实验过程中,通过信号的拾取,转换,分析,培养学生作为一个科技工作者具有的基本操作技能与动手能力。由于电路板采用模块结构,可以灵活组合,以便于各学校根据基本原理配置开出极多的实验,因此我的设计方案采用分体式实验台。
传感器是新技术革命和信息社会的重要技术基础,是现代科技的开路先锋,美国早在80年代就声称世界已进入传感器时代,日本则
