Embodiment Construction

[0043] like figure 1 and figure 2 As shown, the implementation steps of the time synchronization method for the medical Internet of Things in this embodiment include: the boundary server at the data-aware end waits for a synchronization command sent by a clock source in the cloud, and if receiving a synchronization command from the clock source in the cloud, the boundary server sends the synchronization command to the cloud. The clock source is used as a reference node to perform time synchronization; at the same time, the border server detects whether the data acquisition terminal at the data sensing end needs time synchronization, and sends a synchronization command to the data acquisition terminal if time synchronization is required. like figure 2 As shown in the figure, the medical Internet of Things includes the cloud and the data-aware end. The cloud server includes a clock source, which serves as the benchmark for the unified time of the whole network; the data-aware...

Abstract

The invention discloses a time synchronization method, system and medium oriented to the medical Internet of things. In the time synchronization method oriented to the medical Internet of things of the present invention, the boundary server at the data sensing end waits for a synchronization command sent by a clock source in the cloud. The edge server uses the cloud's clock source as a reference node to perform time synchronization; at the same time, the edge server detects whether the data acquisition terminal at the data sensing end needs time synchronization, and sends a synchronization command to the data acquisition terminal if time synchronization is required. The invention uses the boundary server as an intermediate link, can realize the time synchronization of the entire medical Internet of things, ensures that the data collection time of the entire medical Internet of things is accurate and reliable, and the synchronization mode system has good scalability and fast synchronization convergence speed.

Description

technical field [0001] The invention relates to the technical field of the medical Internet of things, in particular to a time synchronization method, system and medium oriented to the medical Internet of things. Background technique [0002] Time synchronization technology is extremely important for IoT technology, especially medical IoT. Devices in the medical Internet of Things often self-organize into a multi-hop distributed wireless network. The work area is relatively scattered, and the entire network system needs to work continuously for a long time. The main task of the devices in the medical Internet of Things is to collect and forward the vital signs of patients in real time. To accomplish this task, it is necessary to achieve time synchronization of the global network or the local network. [0003] At present, there are many time synchronization methods based on reference nodes at home and abroad, such as TPSN, RBS, FCSA and so on. In these algorithms, the refe...
