Abstract

The embodiment of the present application discloses a vehicle monitoring method, device, equipment and storage medium based on narrowband Internet of Things. The technical solution provided by the embodiment of the present application obtains multiple path segments by dividing the path according to the path planning information of the vehicle and the signal coverage information of different base stations on the corresponding driving path, splits the data to be sent into multiple data units, and Store it in the unit linked list, and determine the estimated transmission volume of each path segment under the corresponding average signal strength information and estimated travel time, and extract the data unit from the unit linked list according to the current path segment of the vehicle and the corresponding expected transmission volume , and according to the corresponding average signal strength information, the data unit is combined into multiple data blocks, and the data blocks are uploaded to the base station in turn, and the data blocks of the appropriate size are uploaded to the base station according to the narrowband IoT network conditions of different path segments, reducing The amount of data retransmitted when data transmission fails to ensure the effect of data transmission.

Description

technical field [0001] The embodiments of the present application relate to the technical field of the narrowband Internet of Things, and in particular, to a vehicle monitoring method, apparatus, device, and storage medium based on the narrowband Internet of Things. Background technique [0002] NB-IoT has become an important part of realizing the Internet of Everything. Narrowband IoT can use licensed or unlicensed narrowband spectrum bandwidth, which is conducive to reducing deployment costs and deploying private networks. [0003] NB-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 set in the vehicle, and vehicle monitoring data is collected through the IoT gateway and sent to the base station, and the base station then forwards the vehicle monitoring data to the server for application.
