摘要
本文简要介绍了外径仪的工作原理，外径仪在电缆芯线自动生产线中的实际应用，通过在工控机中使用485接口卡和485／232转换器克服了RS232串行口传送距离短，抗干扰能力差的缺点。给出了外径仪与工控机通信的硬件连接和程序框图。
The principle of Accuscan and application in wire automated production line is introduced in the article. By using 485 interface and 485 to RS 232 converter in industrial control computer, overcome the defect that the communication distance is not long in RS 232 and the interference-free ability is not well.The program chart and the hardware connection between the industrial control computer and Accuscan in wire automated production line are given.
