摘要
针对筒装料管道水力输送过程中管道车瞬时速度测量难的问题,提出了一种新型电磁测量方法,并对该方法进行了理论分析。该方法设计了以ARM控制器为核心的管道车瞬时速度测量系统,系统包括电磁收、发信号调理电路、上位机接收软件及数据库部分。将测速系统装入管道车内,在管道待测量位置加装激励线圈,就能测量管道对应位置处的管道车速度。通过现场实际测量表明该测量方法频率响应快,测量结果准确,安装简单,对管道内物体速度的测量具有重要的应用价值。
In order to solve the measurement problem of instantaneous velocity of the piped hydraulic transportation of tube,contained raw material,the new electromagnetic measurement method was put forward,and the method was analyzed theoretically.The measurement system of instantaneous velocity of the piped carriage based on ARM controller as the core was designed.The system included electromagnetic receiving,signal conditioning circuit,upper computer receiving software and database.The velocity measurement system was installed in the piped carriage,and an exciting coil was installed at the position to be measured,so that the speed of the piped carriage at the corresponding position of the pipe can be measured.The actual measurement showed that the method had the advantages of fast frequency response,accurate measurement result and simple installation,and had important application value in the measurement of the object velocity in the pipeline.
