Abstract
The project aims to develop a platform for supporting Internet of Things - IoT LPWAN, bidirectional, responsible for the acquisition, processing and transmission of data generated by sensing, actuators, that enables the attendance of the needs presented by numerous applications. In its development, the necessary requirements will be observed for the Hardware and Software Platform consisting of: a LPWAN Device, Microprocessor, GPS Location, Bluetooth (BLE), WiFi, Long-life battery, Digital and Analog Interface, Actuators; and a Middleware, Gateway and Application Programing Interface - API. Multi-device communication is challenging in that the sensors marketed by the manufacturers adopt technologies, proprietary protocols, profiles to be studied and contemplated in the system architecture. This will require a survey and development of a flexible, open, customizable structure for capturing and processing the generated data, aiming at customization, performance, scalability and system security. Interoperability and diversity of protocols are the main challenges to overcome. Regarding the LPWAN communication, the technology standards regarding characteristics, certifications, national presence, area of coverage, reliability, costs, and defined to be adopted will be evaluated - LoRaWAN, Sigfox, Lora, NB-IoT, LTE Cat-1, Cat-M LTE. The system provides a contingency of communication via WiFi or Bluetooth (BLE), to send the data not transmitted to the carrier's gateway in order to provide greater security and reliability to the operation. Proof of concept of the LPWAN Terminal, its requirements and specifications, will occur through the integration of an Automotive Fuel Analysis Sensor. The validation of the Hardware and Software Platform in benches and in the field will occur through prototypes installed in the vehicles of the fleet partners. (AU)
