摘要
针对变电站二次设备串口打印速度慢、造价高等缺点,提出一种基于以太网打印协议的变电站二次设备网络打印方案。介绍了具体设计细节以及在变电站内不同通信拓扑下的实施方法,并在打印介质、通信可靠性、打印时间等方面将网络打印与串口打印以及后台打印方式进行了对比。结果表明在保持打印内容不变的条件下,能较大幅度的增加二次设备的打印速度,提高工作效率。
On account of costly but slow serial port printing for substation secondary equipment, this paper puts forward a network printing scheme for substation secondary equipment based on the Ethernet Printing Protocol. It introduces design details of the scheme as well as its implementation method under different communication topologies of the substation. Comparisons are made among network printing, serial port printing and background printing in the respect of printing media, communication reliability and printing time. The results show that this scheme can significantly raise the printing speed and improve working efficiency of secondary equipment under the condition that printing contents remain unchanged.
