鉴于电子护具在体育竞技方面的广泛应用和跆拳道电子护具的发展，提出了基于光纤传感技术的散打电子护具。利用现有光纤微弯传感器的原理和特点，设计出了合适的微弯调制器和各部分发射接收系统。在一定外部击打力作用下光纤会发生不同程度的弯曲，从而可以得到不同的电压值，并根据输出的电压值来判断运动员打击力的大小。实验测试表明，在一定范围内击打力与输出电压值近似成线性关系，从而可实现散打运动的自动评判得分。

In view of the extensive applications of electronic gears in sports contests and the development of Taekwondo elec-tronic gears,fiber-optic sensor-based Sanda electronic protective gear is proposed.On the basis of the principle and characteris-tics of the existing fiber-optic microbend sensors,an appropriate microbend modulator and sending/receiving system of this gear is designed.Fibers are bended to different degrees under the action of certain external impact force,thus different voltage values obtained,which are used to judge the sizes of the impact force.The experimental test results show that in a certain range,the impact force is approximately linear with the voltage values,realizing the automatic evaluation and scoring for Sanda competitions.
