Self-weighing method for intelligent mobile luggage

Abstract

A self-weighing method for an intelligent mobile luggage is disclosed. At least one wheel of a luggage is fitted with a motor therein for driving the wheel. The luggage also includes a microcontrollerunit for controlling the motor to provide the wheel with a driving force. The method includes the steps of, in a case in which the motor does not provide the wheel with the driving force, allowing the luggage to slide freely on a plane and determining first acceleration of the wheel during this period; in a case in which the motor provides the wheel of the driving force, allowing the luggage to advance on the same plane and determining second acceleration of the wheel during this period; and determining the weight of the luggage to correspond to a quotient of the driving force by the difference between the second acceleration and the first acceleration. With this method, the intelligent mobile luggage can be weighed without the use of a separate weighing device or the introduction of a weighing sensor, and the disadvantages of the prior art, such as the need for a separate weighing device or the introduction of a weighing sensor and thus the resulting increase in structural complexityand cost, decrease in reliability and other issues are overcome.

Description

technical field

[0001] The invention relates to an intelligent mobile suitcase, the suitcase has one or more wheels, at least one of the wheels is equipped with a motor, and the motor includes a stator, a rotor and a rotating shaft and is connected to the wheel on which it is located through the rotating shaft To drive the wheels, the luggage case includes a microcontroller unit that controls the motor to provide driving force to the wheels. In particular, the present invention relates to the weighing of smart mobile luggage. Background technique

[0002] Nowadays, suitcases are increasingly becoming an indispensable item in people's lives. With the continuous development of science and technology, people's living standards are gradually improved, and the requirements for suitcases are also getting higher and higher. Luggage suitcases with various additional functions, such as smart suitcases, have emerged.

[0003] Sometimes it is important to determine the weight of a su...

Examples

Embodiment Construction

[0056] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the appended claims.

[0057] The basic idea of ​​the present invention is as follows: adopt modern control theory, design controller and state observer, estimate the weight (mass) of intelligent suitcase as unknown state, estimate the weight of suitcase through the acceleration and deceleration of suitcase. By adopting the invention, the need for a load cell is avoided, which helps to improve reliability.

[0058] The present invention will be further described in detail below.

[0059] The present invention proposes a self-weighing method for an intelligent mobile suitcase, the suitcase has one or more wheels, at least one of the wheels is equipped with a motor, and the motor includes a stator, a rotor and a rotating shaft and passes through The rotating shaft is connected to the wheel where it is loca...
