Abstract: Intelligent electronic scale is a new type of weighing instrument that combines computer communication technology and digital conversion technology. designed and implemented here. An intelligent electronic scale based on 51 single-chip microcomputer was developed. The smart electronic scale mainly includes 5 modules, which are display module, bluetooth module. Main control module, power supply module and sensor module, and explain each module in detail. The linkage of each module realizes tare and restoration, accurate weighing reset function, and upload the data to the mobile phone. Stable and reliable weighing application program with upper computer management software, and ultra-small keystrokes

Sensitive and accurate, to a certain extent, can continue to meet various demands on weighing.

Key words: single chip microcomputer; intelligent electronic scale; bluetooth; weighing sensor

1 Overview

Traditional electronic scales mainly measure the mass of objects, using the principle

It is Hooke's law or the principle of lever balance. But with the modern

With the development of communication and IT technology, traditional electronic scales can no longer fully meet the needs of people.  

 At present, some smart scales can automatically identify the goods on the weighing pan, and the identification is fast. Speed, accuracy, adapt to different lighting environments and various packaging methods. There is also. Some smart scales support intelligent identification and commodity retrieval, lowering the operating threshold. Learning results can also be shared across stores, simplifying multi-store deployment and improving real-time. Improve deployment efficiency, reduce maintenance costs, realize remote deployment and over-the-air technology

(OTA) upgrades. Because of its excellent hardware quality and artificial intelligence, smart scales

(AI) technology, which can ensure long-term stable operation of equipment. some developers make. Using intelligent algorithms, combining weighing with visual recognition and picture shooting. Simplify handling and enable error-free operations in pick and pack applications.

Connect smart scales directly to production and enterprise resource planning (ERP) systems

system that ensures full data visualization and provides users with information about successful fulfillment. Intuitive Proof of Order. In order to achieve accurate measurement, develop with advanced awareness. Development and design, with the main goal of achieving the best quality, designing and implementing a. A smart electronic scale based on a single-chip microcomputer.

Problem formulation and needs analysis

After the designed smart electronic scale is powered on, it enters the welcome interface——

"Welcome to this smart scale design". When an object is placed on the stage

When, the ADC0832 chip immediately sends the data conversion to the microcontroller for processing, and displayed on a liquid crystal display (LCD). The user enters the corresponding product with the key. After the code number of the corresponding product, you can see the name of the corresponding product, the Price, total weight, total price and other information. In this design, especially the. Yes, the weight of the object to be weighed may exceed the range of the electronic scale, at this time it should be

Allow the electronic scale to issue voice prompts to protect the electronic scale and prolong its service. Its measurement range is designed to be 0~9.99kg, and the specific requirements are analyzed as follows.
