Design and implementation of the intelligent electronic weighing system
abstract
The so-called intelligent electronic weighing system is the use of accurate weighing items or the weight of people,it can be intelligently received and feedback information to the user to achieve a convenient and efficient effect. This project has completed the design and implementation of the intelligent electronic weighing system. The system can allow users and electronic scales to carry out human machine voice interaction, and realize data record and upload to facilitate the summary on the .basis of the basic weighing.
Significance and development of the intelligent electronic weighing system are introduced in this project. Then the whole scheme is determined. Then each module is introduced in detail from two aspects of hardware and software. The hardware is mainly composed of the A/D signal conversion module, the speech recognition module, the wireless data transmission module and the data display module. Block, peel and alarm and other modules. The software part mainly focuses on the programming of the master chip, and finally the debugging and summary of the whole function of the system.
Key words: single chip; intelligent electronic scale; speech recognition; wireless data transmission
