Design of Intelligent Flow Pressure Detection System

传统介入式检测系统具有测量精度低、稳定性差、成本高、不易用于检测系统的缺陷。本文通过研究国内外非介入式流量检测系统与非介入式压力检测系统相关文献，分析得出超声波原理既可应用于智能流量检测也可应用于智能压力检测。针对提高测量精度和系统稳定性的问题，利用超声波原理设计智能流量压力检测系统，并采用外夹式安装的时差法超声波进行测量。通过超声波智能流量检测系统与超声波智能压力检测系统的共性研究，将两个检测系统整合设计到同一系统硬件中，设计不同算法和程序，使之成为具有便携式、低成本、可在线检测特点的超声波非介入式智能流量压力检测设备。
Traditional interventional detection system has low measurement accuracy, poor stability and high cost, which makes it difficult to detect system defects. In this paper, by studying relevant literatures of non-interventional flow detection system and non-interventional pressure detection system at home and abroad, it is concluded that the principle of ultrasonic can be applied to both intelligent flow detection and intelligent pressure detection. In order to improve the measurement accuracy and system stability, an intelligent flow pressure detection system is designed based on the principle of ultrasonic wave, and the time difference method ultrasonic wave is used to measure the flow pressure. Through the common research of ultrasonic intelligent flow detection system and ultrasonic intelligent pressure detection system, the two detection systems are integrated into the same system hardware, and different algorithms and programs are designed to make it a portable, low-cost, online ultrasonic non-interventional intelligent flow pressure testing equipment.
