摘　　要：烧结机台车侧板在生产过程中容易产生裂缝,不仅会造成烧结矿掉落,而且使侧板稳定性变差,极易引发安全生产事故。针对烧结机台车侧板安全检测问题,设计台车侧板裂缝检测方案,实时获取侧板图像数据,对比U-Net、金字塔场景解析网络(pyramid scene parsing network,PSPNet)、DeepLab V3+三种不同的语义分割网络,试验结果表明,U-Net网络性能较优,对目标特征提取较好,故采用U-Net对侧板边界及裂缝进行检测。在此基础上,根据裂缝类型、长度及数量设定侧板裂缝安全预警判断规则,构建台车侧板裂缝安全预警检测算法,通过试验验证算法总误检率为0.91%。结果表明,该算法为烧结机台车侧板裂缝安全预警提供技术方案,能降低生产事故,对烧结生产安全具有重要意义。The side plate of sinter trolley is easy to produce cracks in the production process,which will not only cause the sinter to fall,but also make the stability of side plate worse.It is easy to cause safety production accidents.Aiming at the safety detection problem of side plate,a crack detection scheme of side plate was designed and the real-time image data of side plate was obtained.Compared with the three different semantic segmentation networks of U-Net,PSPNet,DeepLab V3+,the experimental results prove that U-Net network have better performance and good extraction of target features.Therefore,U-Net was used to detect the side plate boundary and cracks.On this basis,the safety early-warning rules of side plate cracks were set according to the type,length and number of cracks.After that,the safety early-warning detection algorithm for trolley side plate cracks was constructed and total false detection rate of algorithm is 0.91%.The results show that the algorithm can provide technical solutions of safety early-warning for sinter trolley side plate cracks.It can reduce production accidents effectively and has a great significance for sintering production safety.
