【摘要】 设计并实现了一种基于TMS320VC33的无线数据采集系统,本系统为解决工业自动化中仪器仪表的数据采集和无线传输可靠性差,采样率低,精度差,接口不规范等问题。系统以TMS320VC33作为数据采集系统的主控制器,与AD1674实现了16路12位的数据采集系统,采用nRF903实现了数据的无线发送和接收。经实验证明本系统采样频率高(达到100k),数据传输稳定可靠,系统测量精度高(误差小于0.5%)等特点,可广泛应用于仪器仪表等领域。更多还原

【Abstract】 A wireless data acquisition system based on TMS320VC33 was designed and realized,this system can overcome the problems of bad reliability,low acquisition rate,poor precision and interface irregular on instruments and meters in industrial automation.TMS320VC33 was used as the main controller of data acquisition system in this system,and realized 16-channels 12-bits data acquisition system with AD1674,data wireless sending and receiving was realized used nRF903.It was proved by experiment that this system has characteristics of high acquisition rate(lOOk),stable and reliable data transmission,high precision system measuring(error was less than 0.5%),can be used widely in instruments and meters field.更多还原
