摘要
随着工业应用对信号检测与传输的要求不断提高,新型智能仪表将在市场中占有越来越重要的地位。本文在分析压力变送器基本工作原理的基础上,针对新形势下的生产要求,设计了基于MSC-51单片机的智能压力变送器的数据采集电路、看门狗电路以及接口电路。并设计了相应的数据采集算法、通信协议以及其他软件功能。
Along with the requirements of industrial application of signal detection and transmission continues to improve, new intelligent instrument will play more and more important role in the market. Based on the analysis of the basic principle of pressure transducer on the work under the new situation, according to the production requirements, design a data acquisition circuit, the intelligent pressure transmitter MSC-51 microcontroller watchdog circuit and interface circuit based on. And design the corresponding algorithm of data collection, communication protocol and software function.
