基于物联网的虚拟水文测站构架

Framework of virtual hydrological station based on Internet of Things

传统水文测站通过感知层、通信层、应用层建立水文遥测系统,系统在可扩展性、容灾能力、地理空间要求等方面存在一定的局限和要求。基于物联网的虚拟水文测站架构的提出,可以通过传感采集并将数据传输到短距离无线通信系统,水文测站的物联中心接收到数据后,并对接收到的数据进行分析、处理,然后输出,利用GPRS、北斗等各种通信信道进行数据传输,可传输至各省市县的数据中心。这种方式解决现有遥测系统遇到的常见问题,有利于提高水文测站的可扩展性、稳定性和健壮性,保证水文测报采得到报得出。该架构方式基于物联网概念和传统水文业务的实际情况提出,可为水文测站现代化建设提供参考。

The traditional hydrological station establishes hydrological telemetry system through sensing layer,communication layer and application layer.The system has some limitations such as scalability,disaster tolerance and geographical space requirements.The virtual hydrological station architecture based on the Internet of Things(IOT)can output the data to the short-distance transmission system after sensor collection,and then transmit the data to the IOT center of the hydrological station,by which the data is analyzed,processed and output to the data center of the province,city and county through various communication channels,such as GPRS,Beidou Satellite.This method solves the common problems of the existing telemetry system,improves the scalability,stability and robustness of the hydrological station,and ensures the arrival and delivery of hydrological data.The system architecture is proposed based on the concept of IOT and the actual situation of traditional hydrological services,which can provide reference for the modernization construction of hydrological stations.
