Abstract

The embodiment of the invention discloses a vehicle monitoring method, device and equipment based on the narrow-band Internet of Things, and a storage medium. According to the technical scheme provided by the embodiment of the invention, path division is performed according to the path planning information of the vehicle and the signal coverage information of different base stations on the corresponding driving path to obtain a plurality of path segments, the to-be-sent data is split into a plurality of data units, and the data units are stored in the unit chain table; the estimated transmission quantity of each path segment under the corresponding average signal intensity information and the estimated driving time is determined, data units are extracted from the unit linked list accordingto the current path segment of the vehicle and the corresponding estimated transmission quantity, and the data units are combined into a plurality of data blocks according to the corresponding average signal intensity information; the data blocks are uploaded to the base station in sequence, and the data blocks with suitable sizes are uploaded to the base station according to the narrow-band Internet-of-Things network conditions of different path segments, so that the data volume of data retransmission when data transmission fails is reduced, and the data transmission effect is ensured.

Description

technical field [0001] The embodiments of the present application relate to the technical field of NB-IoT, and in particular to a vehicle monitoring method, device, device and storage medium based on NB-IoT. 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 transmission rate of the narrowband Inter...
