摘要
研制了一种应用于电力保护装置的工业级网络打印系统。该系统使得普通打印机成为局域网中独立的设备,从而降低了成本,使网络打印服务更加灵活便利。系统采用了ARM7微处理器并嵌入μC/OS-Ⅱ实时操作系统,在芯片LPC2378上构建了嵌入式网络打印系统的硬件平台,并对系统的总体设计特点和应用设计做了深入的研究和实现。现场应用实验证明,系统运行稳定可靠,并具备设计安装方便和实时性强等优点。
A technical grade network print system used in power protection equipment is developed. It makes the ordinary printer a independent device in the local area network, reduces costs and makes the job in the network print be more flexible and more convenient. The researched system adopted ARM7 microprocessor within which implanting μC/OS-Ⅱ real time operating system, constructing a hardware platform of embedded network print system on the LPC2378 chip, and having a deep development and implement in the overall design feature and application design of the system. The results of field application experiments indicate that the developed network print system works stably and reliably, and the system also has such advantages as convenient design and installation, strong real-time performance in practice.
