A SOS platform inside automotive vehicles based on Narrowband-Internet of Things (NB-IoT) technology
แพลตฟอร์มการส่งสัญญาณขอความช่วยเหลือภายในโดยใช้เทคโนโลยี Narrowband-Internet of Things (NB-IoT)
This article presented the development of the SOS platform for automotive vehicles by using narrowband-Internet of Thing (NB-IoT) technology which using low-power. The platform is including 1) the signal transmission device in the vehicle 2) the android OS based application for retrieved notifications in smartphones. The transmission device will retrieve some data from several sensors inside the vehicle including temperature, the carbon monoxide level inside the cabin room. These data will be recorded, processed, and report Via AIS Magellan cloud service. As a result, the platform is able to transmit the SOS signal in distance 0.24 to 64 Km. The experiment has shown that the signal was transmitted correctly but there is some delay of signal transmitting time increasing linearly due to the distance. The developed prototype platform can be further developed for further practical use.
