摘要 洛阳理工学院毕业设计（论文） PAGE IV  PAGE 4 皮带机智能检测仪表的开发设计 摘 要 皮带运输机是一种连续运输设备，它是现代传输系统中的一个重要环节。主要用来输送块状、粒状和散状等物料，被广泛用于工业生产中。 本设计主要研究内容为自行开发的智能仪表，仪表的核心采用TI公司的16位低功耗单片机MSP430F147，用该单片机的USATR口与MAX485芯片相连实现与上位机的通信功能。利用单片机MSP43F147与其他芯片实现数字量输入输出电路，主要包括通信接口电路、显示电路、电源电路，采样接口电路。在设计当中主要用到Protel 99 SE软件，用Protel 99 SE软件来实现电路原理图设计部分。仪表软件开发使用C语言，采用模块化编程，方便功能模块的增减。 该保护系统提高了整个智能系统的智能化程度，这使智能化保护仪表也具有很大的应用推广价值。 关键词：皮带机保护，MSP430单片机，Protel 99 SE,智能仪表 Belt Conveyor Design and Development of Intelligent instrumentation ABSTRACT When a continuous conveyor belt transport equipment. It is a modern transport system, an important part. Mainly used to transport massive, granular and other bulk materials, are widely used in industrial production. The main research content of the design of intelligent self-developed instrument that uses the core of ITs 16-bit low-power microcontroller MSP430F147, with the SCM USATR mouth and connected to MAX485 chip to achieve communication with the host computer. SCM MSP43F147 and other chips used for digital input output circuit, including communication interface circuit, display circuit, power circuit, sampling interface circuit. The major use in the design of software Protel 99 SE, with Protel 99 SE design software to achieve the schematic circuit diagram part. Instrument software development using C language, modular programming, to facilitate changes in modules. The protection system has improved the intelligence of the intelligent system, which makes intelligent protection devices are also of great value in applications.
