一种石油设备故障声音定位系统研究

Research of Sound Localization System about Petroleum Equipment Failure

摘要: 本设计以TI公司超低功耗MCU MSP430G2553处理器为核心完成。在一块不大于1 m²的平板四角外侧分别固定安装一个声音接收模块，声音接收模块经过滤波接收石油设备故障位置发出的不正常频率声音信号并将其传输到信息处理模块，声音定位系统控制系统通过查表法根据声音经过空气传播到各声音接收模块的声音信号来判定石油设备故障所在的位置坐标，同时通过12864液晶显示屏将石油设备故障处的X、Y坐标显示出来，从而来制作一个可以检测在500 mm ×350 mm的坐标纸内石油设备故障具体位置的声音定位系统。

Abstract: The design uses TI’s ultra-low power the MCU MSP430G2553 processor as core. We fixed installation a receiver module at all of the four corners of a flat which is not greater than1 m², receiver module receivers the unnor- mal frequency voice signals due to petroleum equipment failure after filtering and transmitted it to the information processing module, control system according to the voice the receiver module received to determine the coordinates of the location of the petroleum equipment failure on look-up table, at the same time 12864 LCD shows the X, Y coordi- nates, so as to produce a sound localization system can determine the coordinates of the location of the petroleum equipment failure in500 mm×350 mmsquared paper.
