SmartAirCity combo Alba-Iulia

Parametrii monitorizați = umiditatea relativă a aerului, temperatura aerului, gaze (monoxid de carbon, dioxid de azot, etanol, hidrogen, amoniac, metan, propan, iso-butan), trafic (numar de masini / interval de timp / banda de circulatie), parking (ocupare/eliberare locuri de parcare)

In Alba Iulia a fost instalat un dispozitiv de tip SmartAirCity in pachet complet.

Sunt monitorizare diverse locuri de parcare dintr-o zona centrala a orasului, senzorii de parcare raportand schimbarea starii locului (ocupat/liber). Senzorii de parcare au fost folositi si pentru detectia parcarilor ilegale, de tip loc handicap sau parcare ilegala in zona „parcare interzisa”.

De asemenea, au fost instalati senzori de trafic intr-o intersectie pentru contorizarea traficului si pentru raportarea numarului de masini intr-un anumit interval orar.

Toti acesti senzori raporteaza date prin LoRa catre un gateway central, numit ComboGateway. Acesta are rol de interfata catre internet/aplicatie web pentru senzorii de traffic/parking, dar contine si o componenta de tip SmartAirCity, masurand diverse gaze/noxe si temperatura/umiditate/praf din atmosfera. Aceste date sunt in stransa legatura cu datele de traffic si se folosesc pentru a realiza un grafic cu evolutia in timp a poluarii/numar de masini/interval de timp.

De asemenea, in componenta sistemului exista un Gateway intermediar, instalat intr-o locatie din oras, pe o cladire, ce are rol de repetor. In cazul unor de senzori de parking, distanta catre gateway-ul central era prea mare, acoperirea radio fiind insuficienta. Astfel a fost instalat acest repetor pentru a asigura o acoperire LoRa mult mai mare si pentru a facilita comunicatia senzorilor curenti, dar si a senzorilor ce urmeaza a fi instalati pe viitor.

Monitored parameters = relative air humidity, air temperature, gas (carbon monoxide, nitrogen dioxide, ethanol, hydrogen, ammonia, methane, propane, iso-butane), parking (occupying / releasing parking spaces)

A SmartAirCity device in full package was installed in Alba Iulia. Various parking places are monitored in a central area of ​​the city, with parking sensors, reporting the change of location (busy / free). Parking sensors have also been used to detect illegal parking places such as spots for disabled ones or illegal parking in the “forbidden parking” area.

Traffic sensors have also been installed at an intersection for traffic counting and for reporting the number of cars within a certain timeframe.All of these sensors report data via LoRa to a central gateway, called ComboGateway. Its role is to serve as an interface to the Internet / web application for traffic / parking sensors, but it also has a SmartAirCity component, measuring various gases / noxae and temperature / humidity / dust in the atmosphere. These data are closely related to traffic data and are used to plot the time / time of the pollution / number of cars / time interval. In addition, in the system component there is also an intermediate Gateway, installed in a location in the city, on a building that acts as a satellite transmitter. In the case of parking sensors, the distance to the central gateway was too high, making the radio coverage insufficient. Thus, this transmitter has been installed to provide far greater LoR coverage and to facilitate the communication of current sensors but also for future sensors that will be installed.
