基于物联网云计算技术的智慧界桩系统研究

Research on Intelligent Boundary Stake System Based on IoT Cloud Computing Technology

针对界桩监管难度大、定位不准确等问题,基于物联网云计算技术对智慧界桩进行研究。采用北斗卫星与全球定位系统相结合的双模定位,为智慧界桩提供精确的经纬度定位信息;利用传感器对界桩的形态、温湿度等数据进行采集;使用窄带物联网对采集到的数据进行收集,并将定位信息和数据信息传输给云计算平台,可实现对界桩异常部分进行报警提醒和远程监控。通过试验验证了双模定位较单独使用全球定位系统有更高的精确度,且稳定性也更好;窄带物联网的通信效果在通信设备数量较多且传输的数据量较多的情况下,其传输功耗低于标准值,满足智慧界桩的通信需求,为界桩的监管提供了一份强有力支持。

In response to issues such as difficult supervision and inaccurate positioning of boundary stakes,the research was conducted on smart boundary stakes based on IoT cloud computing technology.A dual mode positioning system was adopted,combining Beidou satellite and global positioning system to provide accurate longitude and latitude positioning information for smart boundary markers;the sensors were used to collect data on the shape,temperature and humidity of boundary piles;the narrowband IoT was used to gather collected data and transmit positioning and data information to cloud computing platforms,which can achieve alarm reminders and remote monitoring of abnormal parts of boundary markers.Through experiments,it has been verified that dual mode positioning has higher accuracy and better stability compared to using global positioning systems alone;the communication effect of narrowband IoT is that when there are a large number of communication devices and a large amount of data transmitted,its transmission power consumption is lower than the standard value,meeting the communication needs of smart boundary posts and providing strong support for the supervision of boundary posts.
