本发明公开一种基于流水线的多队列顺序化缓冲管理电路及方法，本发明电路采用流水线结构，包括：仲裁电路，从读、写、分配缓冲请求中选取一路进行处理；缓冲槽口状态设置模块，设置请求操作的槽口状态和队列号，分配空闲槽口；缓冲槽口滤除模块，滤除不属于当前操作队列且非空闲态的槽口状态，按头指针对齐；队列槽口选择模块，计算头指针指向槽口起的连续空闲槽口数并更新头指针，选出预备态的槽口；队列槽口优先排队模块，用第一个预备态槽口的指针和预备态槽口数分别更新当前操作队列的读指针和结果数；本发明可以支持多个队列共享一个缓冲空间，各类指令队列能对缓冲进行交叉访问，并对指令结果的写入读出进行顺序化管理。

This paper combines with pipeline delivery of our countrys actual conditions and other methods of detection and location. To the leakage characteristic of the fault to the long-distance natural gas pipeline, a method is raised, which is on the basis of wavelet and negative-pressure-wave to detect the leakage and locate. Jobs in this paper are as follows:Multi-resolution decomposition and reconstruction of wavelet transform is utilized to filter the noises, which the leakage brings the noises of negative-pressure-wave. The research is worked in the wavelet and wavelet packet filter. The wavelet transform have a fast and accurate recognition capability to signal singularity. This paper chooses wavelet technology to catch the break point of pressure signal.

本文结合我国管道输送的实际情况和目前现有的各种泄漏检测与定位方法，针对天然气长输管线泄漏故障的特点，提出了基于小波分析和负压波相结合的方法检测泄漏并定位，其中主要进行了以下几个方面的工作：利用小波变换的多分辨率分解和重构技术，对采集到的管道发生泄漏时产生的负压波信号进行降噪处理，并对小波及小波包优化的降噪效果进行对比性研究；利用小波变换技术对信号奇异点的快速、准确的识别能力，捕捉负压波信号的突变点，从而判断是否有泄漏发生。
