摘　　要：为了提高现在市场上国产喷气织机的纬纱检测技术,提出了一种新的改进方案,该方案采取了数字电位器代替原有模拟电位器,修改前置放大滤波电路,ARM处理器替代逻辑组合电路等措施。实际测试结果表明:该改进方案能够更好地提高喷气织机的信噪比,且在探纬灵敏度和抗干扰能力方面均优于津田驹探纬板FU203。Aiming at improving the air-jet loom weft detection technology, a new method was presented. Digital potentiometers were taken to use instead of the original analogous potentiometers, the pre-amplifieation filter circuit was greatly ameliorated, and the logical combination electric circuit was substituted by ARM processor. The testing results indicate that siginal to noise ratio （SNR） can be improved by the enhanced scheme, and the sensitivity and performance of anti-interference are superior to that of TSUDAKOMA weft detection board FU203.
