NB-IoT-based automatic lifting trolley case

Abstract

The invention relates to an NB-IoT-based automatic lifting trolley case, including trolley box body, lifting lever, processor, pressure control module, power supply, WiFi module and NB-IoT module. Thebottom of the lifting lever is connected with the bottom of the drawing lever box by a spring. The processor is used for generating a lifting signal of the lifting lever and sending the lifting signal to the pressure control module. The pressure control module is used for controlling the rise and fall of the lifting lever by controlling the spring between the bottom of the lifting lever and the bottom of the pull lever box. The power supply is used to power the processor, pressure control module and WiFi module. A mobile terminal is also provided, which is used for sending a lifting instruction to a processor, wherein the processor receives the lifting instruction and generates a lifting signal, the mobile terminal and the processor communicate with each other through a WiFi module in a WiFi environment, and the mobile terminal and the processor communicate with each other through an NB in a network-free or network-poor environment, and the mobile terminal and the processor communicate with each other through a WiFi module. The IoT module communicates. The invention adopts WiFi and NB-IoT two signal transmission methods, to solve the problem of no network signal or poor signal inthe area of use.

Description

technical field [0001] The invention relates to an automatic lifting trolley case based on NB-IoT. Background technique [0002] At present, most long-distance trips are inseparable from the trolley case. The trolley case is an indispensable thing in life. For people who are unwell but have to travel far, the flexible design of the trolley case is particularly important. In the existing technology, automatic trolley boxes mostly use WIFI and Bluetooth transmission control transmission, the service life is short, the cost of data uploading is high, and must be used in a network environment, which is not conducive to large-scale use. Once the network coverage is poor, The automatic lifting function will not be available, which may cause inconvenience in use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic lifting trolley case based on NB-IoT to solve the above-mentioned technical defects in view of th...
