Embodiment Construction

[0043] Such as 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 border server at the data sensing end waits for the synchronization command sent by the clock source in the cloud, and if it receives the synchronization command from the clock source in the cloud, the border server sends the synchronization command from the cloud clock source The clock source is used as a reference node to perform time synchronization; at the same time, the border server detects whether the data collection terminal at the data sensing end needs time synchronization, and sends a synchronization command to the data collection terminal if time synchronization is required. Such as figure 2 As shown, the medical Internet of Things includes the cloud and the data sensing end, in which the cloud server includes a clock source, which serves as a unified time reference for the entire network; t...

Abstract

The invention discloses a time synchronization method and system for a medical Internet-of-things, and a medium. According to the time synchronization method for the medical Internet-of-things, a boundary server of a data sensing end waits for a synchronization command sent by a clock source of a cloud end, and if the synchronization command of the clock source of the cloud end is received, the boundary server takes the clock source of the cloud end as a reference node to execute time synchronization; and meanwhile, the boundary server detects whether the data acquisition terminal of the datasensing end needs time synchronization, and sends a synchronization command to the data acquisition terminal if the time synchronization is needed. The boundary server serves as an intermediate link,time synchronization of the whole medical Internet-of-things can be achieved, it is ensured that the data collection time of the whole medical Internet-of-things is accurate and reliable, and the synchronization mode is good in system expandability and high in synchronization convergence speed.

Description

technical field [0001] The present invention relates to the technical field of medical internet of things, in particular to a time synchronization method, system and medium for 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 working area is relatively scattered, and the entire network system needs to work continuously for a long time. The main task of the equipment in the medical Internet of Things is to collect and forward the patient's vital signs in real time. To accomplish this task, it is necessary to realize the 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 refer...
