Multi-use LED Screen Based on NB-IoT

With the development of the Chinese economy, informatization has become the label of this era, and the frequency of personalized information replacement has become more and more rapid and frequent. This project proposes a dazzling folding LED screen based on NB-IoT [1](Narrow Band-Internet of Things) technology. Through the program interface visualization and NB-IoT data transmission scheme, the problem that the current display screen can not move and control each lamp in real time is solved. Through the mobile phone APP to achieve the broadcast of one or more LED screens [2], and at the same time to use the software-hardware combination to achieve the function, to meet the user's needs to buy, display, and carry easily. Specifically divided into: upper computer module, lower machine driver module, Matrix display module, mobile phone APP and NB-IoT data transmission module.
