摘要
以PHILIPS公司的ARM7TDM I处理器LPC2214为核心,设计并实现了一种容量为128MB的数据记录器。该记录器是一种用于记录工控设备之间交换数据的自动记录设备,其目的是为了辅助分析工控系统的工作情况。实际使用表明,该记录器设计方案可行,且与传统的数据记录器相比:高达128MB的容量,使得通过RS-422连续记录数据的时间大幅提高;使用USB接口,则突破了以往数据记录器使用串口上传数据速度慢的限制,缩短了传输时间。
A kind of design and application for a 128MB memory data recorder based on LPC2214 of Philips was introduced, which could record the exchange data between the industrial control equipmentS and help the engineers to analyze the working state of the industrial control system. Practical application indicates the feasibility of this design scheme. Compared with the traditional data recorder, itS 128MB memory make the recording time through RS-422 increase greatly. Instead of serial port, using USB inteffaee can decrease the transmission time evidently.
