摘　　要：压力测控系统是工业生产过程自动化中的重要测量设备,可以用来测量压力、液位等工程参数。本文就可以同时测量压力和温度信号的,基于总线技术的智能压力测控系统的硬件和软件设计加以介绍。在硬件部分重点介绍了压力和温度传感器模块,Wor1dFIP通信卡以及点阵式液晶显示接口的设计。Pressure transmitter is important measurement device of process automation. It can be used to measure pressure, fluid level and other parameters. This paper introduces the hardware design and software program of a pressure transmitter based on WorldFIP fieldbus technology, which can measure pressure and temperature simultaneously. In the hardware design part, the sensor module, round card based on WorldFIP technology and the interface between dot matrix LCD and Micro-controller is introduced.
