图案代码显示是手工地毯编织的一个重要环节.传统的方法是将图案打印在普通纸上,由编织工人逐行阅读并进行编织.该方法不仅造成编织工人阅读困难,而且容易错码.为此,本文提出了使用大容量存储器和微处理器控制来实现图案代码显示的方法,并采用4 M 位的存储器和ATMEL的89C51 单片机实现了该显示器.设计中采用串口通讯和在线存储器编程方法实现代码写入,使用非易失性存储器存储操作状态以实现开机状态自动恢复.所设计的显示器不仅显示准确、阅读方便,而且具有很好的保密特性.
Pattern code display is an important part of hand-woven carpet. The traditional method is to print the pattern on plain paper, which is read by the weaver row by row and weaved. This method not only causes the weaver to read but also misreads , This paper proposes a method of using the mass memory and microprocessor control to realize the pattern code display, and uses the 4 Mbit memory and ATMEL 89C51 microcontroller to achieve the display. Design using serial communication and online memory programming method code Write, use the non-volatile memory to store the operation state to achieve the automatic recovery of the power-on state.The designed display not only shows the accurate, easy to read, but also has a very good security features.
