The system has the characteristic of precision 、 ascendant full - optical 、 insulation 、 flameproof 、 antijamming emi ( electro - magnetic - interference ) and enduring high temperature . it especially fit for axis torque measurement under atrocious surrounding and has a promising applied future . the paper make a thorough discuss and study on the grating torque sensor and its data collection card 该系统具有测量精度高、优越的全光性、绝缘性、防爆性、抗电磁干扰、耐高温等特点，特别适合于恶劣环境下细长轴的扭矩测量，有较好的应用前景。
Introduced the antijamming in the numerical control system design , from the shield ( including electric field shield , magnetic screen and electromagnetic field shield ) designs mentions , added the absorbing circuit to the perceptual load to suppress the transient state noise to give the specify , might avoid the numerical control system which disturbed creates " softly " the breakdown 摘要介绍数控系统中的抗干扰技术，对屏蔽（包括电场屏蔽，磁场屏蔽和电磁场屏蔽，正确的布线方式）和感性负载加吸收电路来抑制瞬态噪声做了详细说明，可避免干扰造成的数控系统的“软”故障。
