摘　　要：随着数字化技术的快速发展和应用,电子秤已成为称重计量衡器的重要组成部分,因其称量准确、快速、透明度高、结算简单等特点,深受广大商家和消费者的青睐。但以杆秤、台秤和简易电子称为主的商用电子秤,普遍存在精度差、易损坏、难维修的现象,特别是在称重茶叶、药材等轻微物品时测量误差十分明显。因此,设计了一种能够根据重量信息自动选择称重电路以实现双精度自动测量、自动报警、直观显示等功能,更好地满足中小型市场的需求。With the rapid development and application of digital technology,electronic scale has become an important part of weighing weighing instrument.Because of its accurate,rapid,transparent,simple settlement and so on,it is well received by the merchants and consumers.However,in the commercial electronic scales based on pole scale,platform scale and simple electronic name,there is a common phenomenon of poor precision,easy damage and difficult maintenance,especially in weighing the light items such as tea and medicinal materials.Therefore,in this paper,a weighing circuit can be automatically selected according to the weight information to achieve double precision automatic measurement,automatic alarm,visual display and other functions,and better meet the needs of small and medium market.
