在对数据滤波概念介绍的基础上,针对电器检测系统中试验数据采集过程中的干扰问题,采用硬件滤波器与数字滤波器相结合的滤波技术,结果表明硬件滤波与数字滤波相结合方法在干扰较强的环境中效果比较明显,为低压电器检测试验提供比较精确的数据。 On the basis of introducing the concept of data filtering, aiming at the problem of interference in the test data acquisition process of electrical detection system, the filter technology combined with hardware filter and digital filter is adopted. The result shows that the combination of hardware filter and digital filter Stronger environment, the effect is obvious, for low voltage electrical test to provide more accurate data.
