A remote monitoring balance car system based on nb-iot

Abstract

A remote monitoring balance vehicle system based on the NB-IoT comprises a balance vehicle and a cloud server. The balance vehicle is provided with a master control module, an attitude sensor, a voiceinput and output module, a locating module and an NB-IoT wireless communication module. The master control module compares real-time attitude information with preset attitude information, judges whether a driver is in a suspected falling state or not and controls the NB-IoT wireless communication module to upload locating information, a suspected falling event and balance vehicle identifying information to the cloud server when the time of duration of the suspected falling state is larger than a preset value; and the cloud server sends the locating information and the suspected falling eventto a corresponding communication terminal and establishes voice communication between the communication terminal and the corresponding balance vehicle. When a balance vehicle rider is in the suspectedfalling state for preset time, the system can report the suspected falling event in time and establish communication connection between the balance vehicle and the bound communication terminal, and aremote person can conveniently know the suspected falling event and the condition in time.

Description

technical field [0001] The present invention relates to the field of intelligent self-balancing vehicles, and more specifically, relates to an NB-IoT-based remote monitoring self-balancing vehicle system. Background technique [0002] Dynamic balance car, also known as somatosensory car, thinking car, camera car and so on. There are mainly two types of single wheel and double wheel on the market. Its operating principle is mainly based on a basic principle called "Dynamic Stabilization". Use the attitude sensor (gyroscope and acceleration sensor) inside the car body to detect the change of the car body attitude, and use the servo control system to accurately drive the motor to make corresponding adjustments to maintain the balance of the system. It is a new type of green and environmentally friendly product that modern people use as a means of transportation, leisure and entertainment. [0003] Self-balancing scooters seem simple and easy to carry, but they are powerful. ...

Problems solved by technology

[0003] Self-balancing scooters seem simple and easy to carry, but they are powerful. In recent years, they have become a walking tool for young people on the streets. However, the safety factor of self-balancing scooters is low, and there is no brake alarm device. Most parents are worried about the safety of their children and hope to keep abreast of their children. Travel dynamics, and want to know the condition of the child as soon as possible when there is a possible failure
