为适应电力设备测试仪器的低成本、智能化、便携化需求，提出了一种光 IRIG-B/FT3码自适应技术。该技术利用高频时钟对光串口IRIG-B/FT3码流进行处理，并根据两种输入码在编码特征和码流速率上的差异，自动识别光IRIG-B码报文和IEC60044-8（FT3）采样值报文，扩展了智能变电站测试仪器的功能。基于该技术研制的手持式智能变电站测试仪器，已成功应用于多个国内变电站的系统联调和现场测试。实测结果表明该技术的有效性和实用性，从而达到了减少测试仪器接口的数量、降低测试仪器功耗和成本的目的。

To accommodate a low cost, portable and intelligent requirement for test devices of electrical equipments, this paper proposes an adaptive technique for optic IRIG-B codes and FT3 sample value codes. Based on the different structure properties and bit rate between IRIG-B codes and FT3 codes, the technique can automatically recognize those two kinds of codes by processing the input stream through a serial port with high frequency clock signal. This technique extends the functions of test device for smart substation. The handheld test device using this technique has been successfully applied in the system test and field test for several smart substations. The test results demonstrate the validity and practicability of the proposed technique, which reduces the number of ports of test device with decreasing its power consumption and cost.
