| Summary: | 碩士 === 國立政治大學 === 資訊科學系碩士在職專班 === 105 === Generally speaking, the application services of the Internet of Things is constructed in a distributed environment typically include many various devices. In such environments, the provision of service is achieved through the information exchange mechanism among smart devices, which are sensor nodes monitoring and sending data via wireless transmission infrastructure. Based on BLE (Bluetooth Low Energy) and CoAP, this research proposes an architecture for the lightweight smart ward information system. Based on this system architecture, new sensor modules can join the system dynamically. The collected data can be visualized on the web page so that the nursing staffs can adjust the intervention more effectively. To evaluate the proposed system architecture, we also implement a prototype based on the design and then test its performance. The main function of this prototype is to inform the nursing staff of the situation of intravenous infusions voluntarily by collecting the data of intravenous injection or the weight of the blood bags from the sensor modules.
