　　摘 要：傳統水文測站通過感知層、通信層、應用層建立水文遙測系統，系統在可擴展性、容災能力、地理空間要求等方面存在一定的局限和要求。基于物聯網的虛擬水文測站架構的提出，可以通過傳感采集并將數據傳輸到短距離無線通信系統，水文測站的物聯中心接收到數據后，并對接收到的數據進行分析、處理，然后輸出，利用GPRS、北斗等各種通信信道進行數據傳輸，可傳輸至各省市縣的數據中心。這種方式解決現有遙測系統遇到的常見問題，有利于提高水文測站的可擴展性、穩定性和健壯性，保證水文測報采得到報得出。該架構方式基于物聯網概念和傳統水文業務的實際情況提出，可為水文測站現代化建設提供參考。

　　Abstract: 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.
