Wibrometr mikroprocesorowy do pomiaru drgań maszyn

W ramach niniejszej pracy przedstawiono projekt wibrometru mikroprocesorowego do pomiaru drgań maszyn. Zadaniem urządzenia jest pomiar i rejestracja przyspieszeń z możliwością odczytania zdalnego lub z karty SD. Urządzenie powstało na bazie układów ATMega oraz modułu pomiarowego, opartego o scalony układ elektroniczny firmy Analog Devices – ADXL001. Przedstawiono podstawowe dane dotyczące projektu elektrycznego urządzenia. Wykonano porównanie prototypowego systemu pomiarowego z komercyjnym systemem pomiarowym Spider 8.

This paper presents the design of a microprocessor based vibrometer for measuring machine vibrations. The task of the device is to take measurements and record accelerations with the ability to read the data remotely or from the SD card. The device was designed based on ATMega systems and a measuring module based on the integrated circuit electronics Analog Devices - ADXL001. The project was realized on the basis of surface elements (SMD), using the keypad backlit capacitive buttons and a large graphic display. A vibration sensor, developed on the basis of the ADXL001, is characterized by similar parameters to those of transmitters available on the market. The communication protocol (SPI) between the microcontroller and the sensor - after using a suitable converter - allows you to use other types of sensors that can be adjusted through the access to calibration parameters of the vibrometer. The basic data for the design elements of the device are described. A comparison of a prototype measurement system with a commercial measuring system Spider 8 is presented. Preliminary studies were carried out using a vibration exciter, further measurements were made for the acceleration of a body singlepiston compressor. The experiments were conducted in a room designed for the operation of the compressor, under real conditions.
