摘要
为满足矿用风速传感器和煤矿环境监测用气体传感器的检测检验要求,设计了一种基于虚拟仪器的回流式风洞测试系统。其硬件主控单元采用三菱FX系列PLC和三菱A800系列变频器,利用PID控制防爆电机的转速,实现风速的稳定输出;软件开发平台采用LabVIEW,将虚拟仪器技术与测控技术相结合,建立传感器检测系统、数据采集系统、原始数据存储与调用为一体的试验平台,能快速、准确、稳定地进行检测,提高了检测效率。
A reflux wind tunnel testing system based on virtual instrument is designed in order to meet the testing requirements of mine wind speed sensor and mine env ironmental monitoring gas sensor.The hardware main control unit adopts Mitsubishi FX series PLC and Mitsubishi A800 series frequency converter,and uses PID to control the speed of explosion-proof motor to realize the stable output of wind speed.The software development platform uses LabVIEW and combines virtual instrument technology with measurement and control technology to establish a test platform integrating sensor detection system,data acquisition system,original data storage and call,which can quickly,accurately and stably carry out detection and improve detection efficiency.
