摘要
现代物流系统中所用的条码扫描器一般都是有线的条码扫描器。随着科技的进步与发展,这种传统的方式已经渐渐不能满足我们的需要了。本文提出一种基于Zigbee技术的无线扫描系统,并将这一系统应用于现代物流中。我们首先在物流工作现场构建基于Zigbee技术的无线局域网,然后将红外线扫描得到的信号经微处理器处理后通过Zigbee通信模块发射到工作现场的网关节点,再通过有线的方式将网关数据传输到远端的物流中心服务器中,实现工作现场操作人员和物流中心服务器之间的信息交互。
Bar code scanners used in modem logistics system are always wired scanners , With the development of science and technology, this traditional approach has gradually not met our needs. This paper raised a wireless scanning system based on Zigbee technology and used this system in modem logistics . Firstly, we build a wireless LAN based on the Zigbee in work on-site. And then we launch the signal via infrared scanning to the gateway node through Zigbee communications module. Finally we transmit the gateway date to logistics center server through cable manners. So we achieved communications between work on-site operators and logistics center server.
