Abstract

The embodiment of the invention discloses a narrowband Internet-of-Things data transmission method and device, equipment and a storage medium. According to the technical scheme provided by the embodiment of the invention, path division is carried out according to the path planning of the vehicle to obtain a plurality of path segments, the predicted transmission quantity of each path segment underthe corresponding average signal intensity information and the predicted driving time is determined, and the to-be-sent data is split into a plurality of data units and stored in a unit chain table, data units are extracted from the unit linked list according to the current path segment of the vehicle and the corresponding predicted transmission quantity, the data units are combined into a plurality of data blocks according to the corresponding average signal intensity information, and the data blocks are updated to the base station in sequence, according to the embodiment of the invention, the data blocks with suitable sizes are uploaded to the base station according to the network conditions of the narrow-band Internet-of-Things of different path segments, the data volume transmitted each time is reduced, the data volume of data retransmission when data transmission fails is reduced, the data transmission efficiency is improved, and the data transmission effect is ensured.

Description

technical field [0001] The embodiments of the present application relate to the technical field of narrowband Internet of Things, and in particular, to a data transmission method, device, device and storage medium of narrowband Internet of Things. Background technique [0002] NB-IoT has become an important part of realizing the Internet of Everything. NB-IoT can use licensed or unlicensed narrow-band spectrum bandwidth, which is conducive to reducing deployment costs and private network deployment. [0003] Narrowband IoT has penetrated into many aspects of people's work and life, such as shared bicycles, financial payment, security monitoring, vehicle monitoring, etc. For vehicle monitoring narrowband IoT monitoring, an IoT gateway is generally installed in the vehicle, vehicle monitoring data is collected through the IoT gateway and sent to the base station, and the base station forwards the vehicle monitoring data to the server for application. However, under the low t...
