Description

An intelligent weight measuring instrument

technical field

The utility model relates to the field of smart household equipment, in particular to an intelligent body weight and foot code measuring instrument.

Background technique

With the development of microelectronics technology, the application fields of intelligent hardware are becoming more and more extensive. Scales are a common household item that allow people to keep an eye on their body weight at any time. However, most of the scales currently on the market can only measure body weight. They have single functions and uneven technologies, which cannot satisfy people's pursuit of a healthier and more convenient life. .

Online shopping is a rising lifestyle, accepted by more and more people, but because consumers can't choose the shoes that suit their own feet by actually wearing them when buying shoes online, it often causes unnecessary troubles such as returns and exchanges. In particular, the size of the feet of children and adolescents changes constantly during the growth and development process. Parents are prone to inconvenience when buying shoes online for their children. Shoes that are not suitable for their feet will affect the healthy development of their children. Not only that, the size of the feet of the elderly will also change due to changes in their physiological structure during aging, and uncomfortable shoes will bring more damage to the fragile elderly. In addition, the traditional foot measurement method uses a tool ruler or other mechanical manual measurement. Compared with intelligent electronic measuring instruments, it is not only inconvenient to operate, but also leads to large errors due to lack of mastery of measurement skills. Therefore, it is necessary to design an intelligent body weight and foot size measuring instrument, which can not only measure simply and conveniently, but also allow people to pay attention to their own body weight, and can also grasp the size of their feet in real time. It is of great significance for satisfying people's life pursuits and improving people's quality of life.

Contents of the invention

The technical problem to be solved by the utility model is to provide an intelligent body weight and foot size measuring instrument. While the intelligent body weight and foot size measuring instrument can measure the user's weight, it can also measure the measurer's foot size, and at the same time, it can Send the measurement information to the user's mobile terminal.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

An intelligent body weight and foot code measuring instrument is characterized in that: it includes an upper panel and a lower panel, a weighing sensor is fixed between the upper panel and the lower panel, and an OLED display screen is fixed on the side of the upper panel. The front end of the upper panel is fixed with two ultrasonic sensors, and the rear end of the upper panel is fixed with two rear baffles, and the positions of the rear baffles are opposite to those of the ultrasonic sensors.

In order to optimize the above-mentioned utility models, the specific measures taken also include:

Both the load cell and the ultrasonic sensor are signal-connected to the input terminal of the microcontroller under the OLED display screen, and the output terminal of the microcontroller is signal-connected to the Bluetooth module and the OLED display screen.

The load cell is a combination of piezoresistor and HX711AD module.

Described microcontroller adopts the Arduino UNO processor of ATmega328 kernel.

The bluetooth module adopts bluetooth 4.0 module.

Both the upper panel and the lower panel are made of acrylic material.

The work of the load cell, ultrasonic sensor, microcontroller, bluetooth module and OLED display is all provided by the lithium battery pack fixed inside the lower panel.

This kind of intelligent weight and foot size measuring instrument measures the weight data of the measurer through piezoresistors, and sends the data to the microcontroller after processing the data through the HX711AD module. At the same time, the ultrasonic sensor measures the distance between the toe tip and the ultrasonic sensor and the back The distance between the baffle and the ultrasonic sensor is only the length of the measurer’s foot, and the data is transmitted to the microcontroller. The microcontroller compares the data with the internally stored data, and can separately calculate the data according to the characteristics of the data. Men and women can also be distinguished as adults, minors and the elderly. The output of the microcontroller outputs the data and displays the data on the OLED display for the user to understand in real time. At the same time, the data is transmitted to the user through the Bluetooth module. and stored on the mobile terminal, allowing users to observe and understand long-term data.
