Intelligent suitcase with automatic following function

Abstract

The invention discloses an intelligent suitcase with an automatic following function. The intelligent suitcase comprises a box body, a processor module, a Bluetooth communication module, an obstacle avoidance module, a motor drive module and a motor module; the processor module comprises a processing chip, a debugging interface, a reset circuit, a reset chip, a mini jumper, a No.1 communication interface and a No.2 communication interface; the Bluetooth communication module comprises a Bluetooth module and a voltage conversion chip; the obstacle avoidance module comprises an ultrasonic moduleand an ultrasonic probe; the motor drive module comprises a Hall filter circuit, a non-inductive detection chip, a non-inductive detection circuit, a current drive chip, a grid drive chip, a motor drive circuit and a current detection chip; and the motor module comprises a three-phase direct current brushless motor and a Hall sensor. The intelligent suitcase can realize the following function thatthe suitcase can follow a user to walk at any time, the hands of the user are liberated, and the daily increasing demand of the user is met.

Description

technical field [0001] The invention relates to an intelligent suitcase with an automatic follow function, which realizes the follow function of the suitcase following the user at any time, liberates the user's hands, and satisfies the ever-increasing needs of the user. Background technique [0002] Most of the suitcases currently on the market have a single multi-function structure and a common shape, which can only meet the basic requirements of people. People's demand for suitcases is developing from basic luggage placement to diversification, complexity, and individualization. At present, in the environment of continuous improvement of production technology and deepening requirements for automation technology, many countries in the world are actively conducting research, development and design of intelligent equipment. With the gradual integration of smart homes into daily life, intelligent suitcases have gradually entered people's field of vision. [0003] The smart s...

Problems solved by technology

However, due to the influence of the indoor environment, the ordinary GPS positioning method will be greatly disturbed, and the error of the user's positioning accuracy is relatively large, and the automatic following function cannot be fully realized. In many occasions, it will also be affected by different degrees of interference and influence.

In addition, because the suitcase needs to follow the user to walk and needs the support of the motor, the type, load and use of the motor also affect the weight of the checked luggage, and the energy consumption of the control system will also affect the battery life of the smart suitcase
