【摘要】 制定了电机故障检测管理系统上位机与下位机之间的通信协议,基于Visual Basic6.0,采用MSComm控件设计了RS-232串行通信程序,采用ADO方式实现了Visual Basic 6.0与Ac-cess数据库的连接,开发了基于MDI窗体的上位机人机界面,实现了上位机——PC机对底层数据的接收、存储和高级管理。实际应用结果表明,所设计的上位机软件具有界面友好、操作方便和稳定性强等优点。更多还原

【Abstract】 The communication protocol between host computer and slave computer of the motor fault detection and its management system are designed.Based on Visual Basic 6.0,the RS-232 serial communication program is designed by using MSComm.The connection between Visual Basic 6.0 and access database is actualized by ADO mode.Based on MDI window,the host computer MMI(man machine interface) is developed.Data receiving,storing and managing are realized by host computer(PC).The application results indicate that the designed host computer software has the merits of friendly interface,convenient operation and strong stability.更多还原
