摘要
企业ERP(EnterpriseResourcePlanning)系统为了对数控机床进行监测 ,要求在数控系统PLC和机床之间载取信号 ,数据采集量大 ,更新ERP数据库迅速 ,实时性能要求高 ,采集过程中不能影响数控机床的正常工作 ,这里采用ATMEL公司的 89C5 1单片机构建数据采集监测系统 ,信号预处理系统很好地实现了数控系统和数据采集系统的电平匹配和电气隔离 ,输出系统采用串行通讯和TCP IP数据传输方式将数据写入ERP系统数据库 。
In ERP system,NC machines are real time watched on. So lots of signals in NC system,especially in PLC,should be rapidly gained. At the same time,the NC machines can run well. Here,89C51 made by ATMEL Co.is used to design the monitoring system. In the system,before the signal form the NC system is imported to 89C51,it has been processed in order that it can be received by 80C51,and the processed signal has been already insulated with the signal from the NC system. So,The relation between the NC system and the NC machine is not affected by the monitoring system. Though RS232,RS484 serial protocol and TCP/IP protocol,datum gained by 89C51 can be send to the database in ERP system. The system has been practiced very well.
