四川理工学院毕业设计（论文）智能温度仪表设计学 生：杨志刚学 号：专 业：自动化班 级：20指导老师：陈昌忠四川理工学院自动化与电子信息学院二 O 一二年六月摘要传感器是人类了解世界的重要工具，它们能精确检测我们感兴趣的各种物理量，为控制和决策提供依据。在信息时代，人类已经难以独自处理如爆炸般涌现的信息了，我们希望传感器能够更加智能，比如能够独立完成信号采集、数据分析、结果报告以及信息共享等。因此，智能传感器应运而生。本设计介绍智能温度传感器应用系统设计技术，构建通用的软硬件开发平台，并展开应用设计实验，包括智能传感器的基本概念，基于 dsPIC 系列数字信号控制器设计智能温度传感器的方法。采纳能适应各种环境和应用的敏感元件：J 型和 K 型两种热电偶，能够测量—270～+1370℃范围内的温度。尽管这只是一个基本设计，但是这里所描述的应用技术却可以很容易的扩展到更复杂的应用中，比如温度控制与检测应用。关键词：温度；传感器；dsPIC 系列；通信；电路ABSTRACTThe sensor is the important tool of human understanding of the world, they can precisely testing we are interested in all kinds of physical quantities for control and decision provides the basis. In the information age, the human has been difficult to deal such as an explosion as the emerging information, we hope that the sensor can more intelligence, such as independently signal acquisition, data analysis, the results report and information sharing and so on. Therefore, intelligent sensor arises at the historic moment. This design is introduced intelligent temperature sensor technology application system design, the construction of the general hardware and software development platform, and spread application design experiments, including intelligent sensor of the basic concepts, based on dsPIC series digital signal controller design method of the intelligent temperature sensor. Using can adapt to the environment and application of sensitive components: thermocouples. Support J type and...
