【摘要】 利用基于IEEE 802.15.4的IP-Link1200模块,设计并实现了能够实时接入现有蜂窝网络的无线传感器网络的验证系统。该方案工作于900 MHz或1 800 MHz的GSM(全球移动通信系统)网络的SMS(短消息业务)平台,把从目标区域采集到的温湿度参数传送给位于远程的任务管理中心。用户只需用普通的支持短消息的手机,向任务管理中心发送固定格式的短消息,就可以实时地获得任意一指定节点的温湿度参数。另外,也可以通过Internet打印历史报表。更多还原

【Abstract】 With the IP-Link1200 module based on IEEE 802.15.4,a scheme of wireless sensor network which can in real time access existing cellular networks is designed and implemented.The data of temperature and humidity which are collected in target area are transmitted to the remote center of management,via SMS(Short Message Service) of existing GSM(Global System for Mobile communication) network at 900MHz and 1800MHz.Sending fixed format SMS to the management center,the consumers can acquire real time data of temperature and humidity.Furthermore,the history reports can be printed online.更多还原
