摘要
根据微波传播速度快、微波传播模式与边界条件有关等特点,开发了基于微波技术进行输气管道泄漏检测的新方法。提出了管外定位、管内双发射双接收定位和管内单发射单接收定位等3种方式,并通过实验验证了这种检测方法的可行性。最后阐述了这种检测新方法用于实时在线检测尚存在的问题及发展前景。
According to the characteristics of quick microwave transmission, its transmission mode being related with boundary conditions, a new method for leakage detection for gas transmission pipelines is established based on microwave technology. Three patterns, such as positioning outside pipeline, dual emission and dual receiving positioning inside the pipeline and single emission and single receiving inside the pipeline are proposed, and the feasibility of the method is demonstrated by experiment, and the problems and prospects of real-time and online detection of the new method are described eventually.
