Testador de cabo digital com informação de temperatura e umidade utilizado em sistemas de termometria com comunicação TIA/EIA-485

Abstract

The present study deals with the realization of improvements for a digital cable tester with temperature and humidity information with TIA/EIA-485 communication, being portable and discarding the use of notebooks, improving locomotion, streamlining the testing process and eliminating possible damage and loss of high-cost equipment. Currently, the process is limited because it does not have a tool that is easy to use and because it is dependent on other physical means (converters, notebooks and software). Based on this premise, this work aims to develop a product to read the sensors of the Qualycable cable. The tester requests temperature and humidity data provided by the SHT15 sensor, these data are sent via TIA/EIA-485 communication to the master product, which will be processed by a LPC2368FBD100 SMD microcontroller, responsible for acquiring and storing the data received from the cable sensors. Therefore, this process will be visualized and commanded by an LCD display to make possible to analyze the temperature and humidity data reported by the slave sensors, being able to detect sensors with and compliance. This project will be developed in an electronics company in Rio Grande do Sul, through the making the prototype.
