摘要
针对磨床、风机等只需要进行单面动平衡测试的机械设备动平衡检测需求,提出基于STM32F04配合AD7606的信号采集系统,用于采集和传输由振动传感器所采集到的转子的振动数据,振动数据通过串口传输传送到STM32F103微型处理器上及上位机,在上位机上进行数据处理,用于现场动平衡检测。相对于以前的动平衡检测,通过在STM32F103内写入动平衡算法,应用采集系统传输过来的数据进行动平衡计算。将计算所得的不平衡量及其相角数据显示在STM32F103上的LCD屏,这样除去可以在用于检测的上位机上观察振动值,还可以通过观察LCD屏实时显示机器的振动值。通过实时显示的振动值判断该机器是否处于正常平衡状态。提早发现设备的异常振动,进行处理。防止出现更加严重的问题。
According to the dynamic balance detection requirements of only needing one-sided dynamic balance testing for the grinding machine,fan and other mechanical equipments,a signal acquisition system based on STM32F04 and AD7606 to collect and transmit the vibration data of the rotor collected by the vibration sensor is proposed.And the vibration data is transmitted to STM32F103 microprocessor and upper computer through serial port,and the data is processed on the upper computer to be used for field dynamic balance detection.Compared with the previous dynamic balance detection,the dynamic balance algorithm is written in STM32F103,and the data transmitted by the acquisition system is applied to the dynamic balance calculation.The calculated unbalance and its phase angle data are displayed on the LCD screen of STM32F103,so the vibration value can be displayed in real time by observing the LCD screen in addition to the vibration value can be observed on the upper computer for detection.The vibration value displayed in real time is used to judge whether the machine is in normal balance state.The abnormal vibration of the equipment can be found in advance and is dealt with to prevent more serious problems.
