The Gauge block calibration information system builds upon an undergraduate thesis titled: Web Application for Analysis of Length Standards Measurement Results Obtained by Differential Method, Teo Braun – FSB, 2015. The undergraduate thesis covered the topic of automating paperwork for the purpose of making gauge block certificates, utilizing web technologies such as HTML, CSS, Javascript, PHP, SQL and AJAX. Continuing the cooperation with the National laboratory for length, this work will build upon the previous topic and expand it with developing the hardware for establishing a communication link between the Mahr Milltron 1240 measurement device and our website. This work will also focus on implementing web security to provide an industry ready product. The centerpiece of our hardware, we'll be a credit card-sized computer, the Raspberry Pi 3, along with a serial port module. We will transform our Raspberry Pi computer into a web server using the following software: Apache 2, PHP 5, MariaDB and phpMyAdmin. We will also be adding access point capabilities with the use of DNSmasq and HostAPD software. The communication link between the measurement device and our website will be established by utilizing Python and PHP with the help of virtual memory for interchanging variables. We will round up this thesis by implementing user authentication with special regard for security measures in order to protect against SQL injecting, session hijacking, physical and brute force attacks. The end result of this thesis will be an industry ready product, that will save time, money and increase reliability by completely eliminating the human error in the process of gauge block measurement and certification.
