题 目 车用电磁继电器后端制程计算机量测与控制系统研制 英文题目 Development of a Computer Measurement and Control System for Back-end Processes of Automobile Electromagnetic Relays 摘 要 国内许多车用电磁继电器制造商均没有车用电磁继电器装配及检测自动化生产设备，仅能依赖人工做逐一检测及装配，不仅耗费时间及人力成本，而且生产速度慢、产品质量不稳定。另外，面对淡旺季或订单多寡状况，人力的调节问题很难处理。因此，本文主要目的在研制一套适于车用电磁继电器装配及检测自动化设备计算机量测与控制系统，协助车用电磁继电器制造商将生产制程自动化，提升生产速度及产品质量。 此计算机量测与控制系统硬件架构采用由 RS485 总线、个人电脑及自行设计 PIC 控制模块所建构成分布式监控系统架构，其中PC 当主控制器及以 PIC 控制模块为奴控制器，其中 PIC 控制模块包含自行设计检测及驱动电路。而软件部分包含以 LabVIEW 设计PC 端监控程序及 PIC 控制模块控制、通讯及量测程序。系统经测试，可达成装配及检测自动化控制，且检测数据可传送至计算机端存文件供建立产品履历。检测功能可达成电磁继电器电气接脚受力测试及电气特性量测，满足合作厂商需求。 关键词：车用电磁继电器；分布式监控；计算机量测与控制；电气特性量测；接脚受力测试 Abstract Many automobile electromagnetic relay manufacturers lack automated assembling and measurement equipment, and the assembly and measurement processes can only rely on handwork. Thus, not only the cost in both time consuming and man power is large, but also the production speed is very slow and the product quality is quite unstable. Therefore, the main purpose of this thesis is to develop a computer measurement and control system for automated assembly and measurement of automobile electromagnetic relays. It can help manufacturers automate the production process and promote production speed and product quality. The developed computer measurement and control system in this thesis employs the distributed monitoring and control system architecture which consists of a RS485 bus, a personal computer (PC) and several self-designed PIC control modules being include measurement and driving circuits, and the PC plays the role of master controller and the PIC control modules play the roles of slave controllers. Besides, the developed software include the monitoring and control program in PC designed by using LabVIEW package and the control, measurement and communication programs in the PIC modules. The experiments approve that the developed system not only can functionally approach the automation in assembly and measurement, but also can s
