摘要
在工业现场中常需要对某一个量(如温度、压力及流量等信号)进行采集和控制,有的还需要对数据进行远程传输、在控制室中对参数的变化趋势进行直观展示,这就需要一种数据采集与远程网络发布系统。本设计从实际应用出发,以STM32为核心控制器实现双路数据采集,利用NRF无线通信模块进行无线数据传输,并采用Lab VIEW软件实现上位机数据的显示和网络发布,达到数据共享的目的。详细阐述了数据采集和无线通信的原理,利用Altium Designer实现PCB设计,搭建实验平台完成设计内容。实验表明:该系统数据采集精确可靠、数据通信快速稳定,并且在局域网内实现了数据的网络发布。
A data acquisition and remote network publishing system was designed for the signals like tempera- ture, pressure, flow and their transmission and visualized display. In which, it has STM32 employed as core controller, the NRF wireless communication module adopted for wireless data transmission and the LabVIEW software based to display the data and realize network publishing; in addition, the principles of data acquisi- tion and wireless c, ommunication were elaborated and making use of Ahium Designer for PCB drawing was im- plemented, including the establishment of test platform to complete the design. The test results shows an accu- rate and reliable data acquisition, fast and stable data communication and the data publishing within local area network (LAN).
