摘　　要：现有的气体检测仪在技术上无法准确检测现场发生的有毒或可燃气体的泄漏;为了保证安全生产和科学管理,开发并应用适合有毒或可燃气体泄漏的检测系统,具有重要意义;提出了一种分布式多传感器气体检测系统的通用结构,研究了可用于该检测系统的自适应加权数据融合算法;最后介绍了一个应用实例,实验结果显示该检测系统识别准确,不仅能够解决气体传感器交叉敏感问题,而且具有智能化和多功能化等优点。The existing gas detecting instrument can＇t detect the leaking out of the poisonous or flammable gas. To ensure the safety of production and scientific management, it is very important to develop a detecting system suitable to the leak out of the poisonous or flammable gas. A general architecture of the distributed on--line gas detecting system is proposed. The adaptive weighted fusion algorithm is presented. At last, an application example is introduced, the research results show that the identification of the system is precise. It not only solves the problem of the gas cross sensitivity, but also helps to realize the artificial intelligence and multifunction.
