Research on a General Intelligent Information Service System for the Internet of Things **

With the rapid increase in information quantity in the Internet of Things (IoT) era, traditional methods of acquiring information can no longer meet the present situation of diversified demand for information acquisition. In this paper, an open general intelligent IoT information service system based on Bluetooth Low Energy (BLE) tags, mobile devices and cloud services is studied and designed. On the one hand, the system deploys the BLE tag in the application object. On the other hand, it automatically selects the BLE tag in real time and obtains the corresponding information of the tag in the cloud through the self-developed Mini Program. Meanwhile, a data storage servicer is designed and developed based on the public cloud to store the BLE tag and the data of application object. After the final multi-scenario test, the system has good scalability, and has the characteristics of real-time, efficient and intelligent.
