基于XBee的无线数据采集系统开发和应用

为了及时、方便地获取车间现场数据,研究开发了一种基于XBee模块的无线数据采集系统,包括手持式数据采集器及连接数据服务器的接收器。手持数据采集器以8052单片机为控制核心,集成了XBee无线通信模块以及满足PS/2协议的条码阅读模块,可通过数字小键盘、条码阅读器在车间现场采集各种工票及其进度等离散数据,并实现实时无线传输。介绍了该数据采集系统的设计原理及其软硬件系统,以及在某企业生产车间的实际应用。实际应用结果表明,该系统使用方便,安全性好,适用于生产现场的离散数据采集和无线传输。

Development and application of an XBee-based wireless data collection system

In order to collect field data in the workshop quickly and conveniently,an XBee-based wireless data collection system was developed,which included a handheld data collector and a transceiver connected with the data server.An 8052 microcontroller was taken as its main control chip,an XBee radio freqency(RF) module,a PS/2 compatible bar code reader,and a numerical keypad were integrated in the handheld data collector.The field data can be collected with keypad and bar code reader,and transmitted wirelessly an...
