新型机车速度传感器检测仪中串行通信系统设计

Design of serial communication system for the locomotive speed sensor detector

针对传统的机车速度传感器检测仪功能的不足,设计了一套串行通信系统方案。系统采用RS-232接口与V isualBasic串行通信控制技术,分别对下位机和上位机进行系统功能扩展和设计,并通过对Excel使用对象链接及嵌入(OLE)自动化技术,实现数据报表的生成。

In view of the functional limitations on the traditional locomotive speed sensor detector, given a design of serial commu- nication system. The system used RS-232 serial communication with Visual Basic controling technology, respectively expand the MCU function and design a procedures, and through the using of OLE automation technology for Excel, the system makes a data statement.
