基于CAN总线的活塞销外圆直径监测系统

摘要

针对活塞销生产质量现场监测的现状,设计了一种基于CAN总线技术与数据库技术的监测系统,实现了活塞销外圆直径的在线检测和测量数据的统一管理.该系统将电涡流传感器作为主要测量器件,结合STC89C58单片机与CAN接口器件设计数据采集节点,利用Delphi语言设计数据库和用户界面实现测量数据和结果的存储和实时显示.实验证明:系统运行稳定,测量结果准确.%A remote monitoring system based on CAN-bus and database is developed to improve the on-line detection condition of the piston pin. The system can accomplish the integrated management of the excircle diameter measuring and data processing of the piston pin and utilizes eddy current transducer ( ECT) as main measure device, STC89C58 microcontroller unit (MCU) and CAN-bus interface device as data acquisition board. The database and graphical user interface ( GUI) are developed by programming Delphi procedure to achieve the storage and real-time display of the measuring data and results. The experiment result proves that the system runs stably and its measuring data is precise.
