基于隔离电路的并口设备数据获取系统设计
资料介绍
为了实现对那些仅有标准打印接口的陈旧设备的信息化改造。本文在分析并口通信、设备与打印机交互信息原理的基础上，设计了一款基于隔离电路的并口设备数据获取系统。该系统可以在不影响设备与打印机正常工作的前提下，截获设备与打印机的通信信息，通过这些信息还原设备的原始打印内容。实际应用表明，该系统达到了设计要求，实现了信息的有效共享和使用。
In order to realize information technology transformation of old device which only has standard print interface. The paper proposes and designs a parallel port printer data interception system based on the analysis of the theory of parallel port communication and the theory of the communication between device and printer. The system can capture the communication info of device and printer without disturbance to device＇s and printer＇s normal work, and use the info restore the original content the device want print. The experiment and application show that this system achieves the effective sharing and uses of information, and achieves the design requirement.
