| Popis: | The resulting of advanced technology, the size of Personal Computer (PC) was reduced into the same size as cigarette box. Thus, the Brinell-macro-hardness tester used Raspberry Pi 3 (RPi3) Model B to acted as the Data Acquisition System (DAS) or the mini-PC which used for measuring of Active-Weight-Loading (AWL) parameters. This DAS used the triplex of force-resistive sensors equipped using IC-MCP3008 and interfaced with RPi3. This IC was used to converse the analogue signal of AWL to 10 bits of the digital signal, and then, the digitalized-data were transferred through the Serial Peripheral Interface (SPI) of RPi3, respectively. In the acquisition procedure, the real-time of measuring-data were revealed using the Graphical User Interface (GUI) which developed using the python language version 2.7. Consequently, it was perceived that this DAS can be fabricated using simple and low-cost design. Therefore, this contrivance can be regularly used for AWL measurement which is the one part of Brinell hardness measurement. Finally, the fabrication of electronic parts and software interfacing which manipulated using RPi3 were presented in the discussion section. |
