Mikrokrmilniško voden industrijski semafor

Rakar, Jan (author), Murovec, Boštjan (mentor)

Industrijski semaforji so bistven del industrijskega okolja, ki operaterjem prek svetlobnega signala sporočajo stanje stroja. Tradicionalni semafor vsebuje večsegmentne sklope različnih barv, ki so pritrjeni na podstavek signalnega stolpa. Za krmiljenje posameznega segmenta se uporabljajo signali programirljivega logičnega krmilnika (PLK). Zaradi števila vsebovanih segmentov je ta rešitev cenovno neugodna. V tej diplomski nalogi je opisana zasnova industrijskega semaforja, ki za ustvarjanje celotnega nabora ustreznih barv uporablja le dva svetlobna segmenta v obliki programirljivih svetilnih diod tipa WS2812. Dva taka elementa potrebujemo, ker morata na semaforju goreti dve barvi hkrati. Vezje upravlja mikrokrmilnik PIC, ki krmili tudi zvočni signal. Semafor vsebuje tudi modul Esp-01s za sporočanje stanja stroja strežniku ThingSpeak.

Abstract

Industrial signal lights are an essential part of the industrial environment, communicating machine status to operators via a light signal. A traditional semaphore contains multi-segmented assemblies of different colours mounted on the base of a signal tower. The number of segments contained makes this solution cost-prohibitive. This thesis describes the design of an industrial signal light that uses only two light segments in the form of WS2812 programmable light-emitting diodes to generate the full range of appropriate colours. Two such elements are needed because the signal light needs to display two colours at the same time. The circuit is controlled by a PIC microcontroller which also controls the audio signal. The semaphore also contains an Esp-01s module to communicate the machine status to the ThingSpeak server.
