摘要
设计了一种多功能全自动布洛维硬度计,可以测量布氏、洛氏和维氏的硬度值。硬件设计采用ARM+高精度AD+组态屏的解决方案,系统软件主要包括电动机控制、传感器数据采集、GUI和与外部通信四部分。实验结果表明,设计的硬度计在布氏、洛氏以及维氏3种硬度试验中,全量程测量误差满足国家标准规定;试验力误差在±1%以内,符合制定的设计要求。设计的硬度计可在硬度测量的全过程均采取自动化操作,实现一键打压、读数、复位,达到高精度的控制与数据处理。其结构设计合理,运行稳定,操作简单,该设计已成功应用于某些工业现场,具有一定的推广应用价值。
A multi-functional fully automatic Blowie hardness tester,which can complete the measurement of Brinell,Rockwell and Vickers hardness values,is designed.The hardware system adopts the solution of ARM+high precision AD+configuration screen.The system software mainly includes four parts:motor control,sensor data acquisition,GUI and external communication.The experiment shows that the full range measurement error of the designed hardness tester in Brinell,Rockwell and Vickers hardness tests meets the national standard.The test force error is within±1%,meeting the design requirements.The designed hardness tester can achieve automatic operation in the whole process of hardness measurement,realize one key pressing,reading and resetting,and achieve high-precision control and data processing.The structure design is reasonable,the operation is stable,and the operation is simple.The design has been successfully applied to some industrial sites and has certain promotion and application value.
