The level information of materials in industrial production needs to be clearly grasped. Level measurement of solid materials due to technical difficulty and high cost of measurement, there is no rich experience in liquid material measurement systems. In order to solve the problem of solid material level measurement in industrial production, a vibration-based solid material level meter measurement module is designed. By collecting the vibration signal, the spectral peak of the vibration signal and the corresponding frequency and its corresponding material level information can be obtained by the least square fitting to obtain the relationship between the vibration signal spectral peak and the corresponding frequency and the material level. Select STM32F103ZET6 microcontroller as the main control unit. ADXL345 acceleration sensor for vibration signal acquisition. The XTR116 voltage-to-current chip outputs the material level information in the form of a 4-20mA standard industrial current loop. A material level system is designed to obtain material level information by collecting vibration signals and performing frequency spectrum calculation. The module has low cost and high accuracy, and meets the requirements of solid material level measurement under industrial conditions.
