摘要
为满足企业用户日益对工业现场无线通信的需求,提出了基于无线HART的多功能智能圆卡设计。设计中无线HART模块采用RFM公司的XDM2510H;信号调理部分采用MAX1452芯片,负责对原始信号进行放大、补偿和校准;MCU则选取MSP430F5438A单片机,对经调理的信号进行采集、分析和处理;数据分析结果通过XDM2510H经无线网送达网关提供给上位机使用。圆卡可以接入不同的传感器,并载入对应的软件即可快速开发出一款无线HART变送器,最终实现了无线HART仪表开发难度降低、节约了开发成本。
In order to meet the growing demand of industrial wireless communication enterprise users, we propose a multi - functional smart card design based on wireless HART. The XDM2510H is adopted for the wireless HART module, and MAX1452 for the signal conditioning module, which is responsible for the original signal amplifi- cation, compensation and calibration. The MCU adopts MSP430F5438A microcontroller for the modulation of signal acquisition, analysis, and processing. Data analysis results are sent by XDM2510H via the wireless network to the gateway for PC. The smart card can access different sensors and load corresponding different software, enabling quick development of a wireless HART transmitter, thereby reducing the difficulty of wireless Hart instrument research and saving the cost of development.
