基于称重传感器的电子元器件智能管理系统

Intelligent Management System of Electronic Components Based on Load Cell

摘要: 针对人工管理电子元器件存在的工作效率低、实时性差和人工成本高等问题，设计并开发了电子元器件智能管理系统。该系统包括电子元器件智能存储柜、服务器端和Web客户端。采用双孔平行梁式传感器结合HX711采集元件重量信息，以实现元件的准确计数；利用RFID识别用户，结合电控锁实现柜门控制；利用语音模块与串口屏实现信息播报、库存显示与查询。利用SSM框架搭建后端服务器，利用MySQL数据库存放元件信息、用户信息和元件领取记录；利用Vue开发Web端。经系统测试表明，该系统具有元件自动计数、用户权限管理、元器件领存数据存储和可追溯等功能。电子元器件的平均计数准确率为98.8%，系统平均响应时间为3秒。

Abstract: As an essential material in the intelligent manufacturing process, electronic components have the characteristics of small size, high value and kinds of types. The manual management mode of electronic components has the problems of low efficiency, non-real-time and high labor cost. The intelligent management system of electronic components was designed and developed, including electronic components intelligent storage cabinet, server side and Web client. The double-hole parallel beam sensor combined with HX711 was used to collect the weight information of components for automatic counting; RFID was used to identify users, and combined with electric locks to realize cabinet door control; voice module and serial screen were used to realize information broadcasting, inventory display and query. The SSM framework was used to build the back-end server; the MySQL database was used to store component information, user information and component receipt records; Vue was used to develop the web side. The test showed that the system had the functions of component automatic counting, user rights information management, component management, data record storage and traceability. The average counting accuracy of electronic components is 98.8%, and the average response time of the system was about 3 seconds.
