摘　　要：泄漏检测是化工安全防范中重要的部分,传统的化工企业泄漏检测过于依赖气体的浓度特征,当对于大范围的化工毒气泄漏时,扩散速度随机性很大,很难准确定位大范围的泄露源头;为此提出基于PSO-BP的化工企业泄漏点定位技术,将毒气传感装备节点形成一个监测网络,对节点跨区域采集到的浓度特征完成检测;对采集得到的传感器信息使用PSO全局搜索算法进行泄露传感器节点最佳浓度寻优操作,完成化工厂的污染源定位;实验结果证明,这种方法的泄漏点定位准确,定位误差不超过10m。Leak detection is important to chemical safety and protection, the traditional chemical enterprise leak detection too dependent on gas concentration characteristics, when for a wide range of chemical gas leakage, diffusion velocity randomness is very large, it is difficult to accurately positioning a wide range of leakage source. Therefore based on PSO -- BP chemical enterprise leakage point positioning technol- ogy, will form a monitoring network of gas sensing equipment node, the node cross area to the collected concentration characteristics comple- tion of the inspection. To collect information for sensor using PSO global search algorithm for leakage sensor node optimal concentration opti- mization operation, complete chemical plant pollution positioning. The experimental results show that this method of leak point positioning accuracy, positioning error is no more than 10 meters.
