The work presented in this paper is the design and implementation of an electronic platform, based on the SDK STM32f4-Discovery, dedicated to the implementation of a communication system for the automatic identification of bus using RFID technology. Our goal is to develop passive RFID readers manufactured with materials that respect the environment and having a reduced size. Index Terms—RFID Reader, Blind, Spiral Antenna, STM32 . I.INTRODUCTION(HEADING 1) RFID technology (Radio Frequency Identification) has many applications and is increasingly present in the life everyday people. Opportunities suggests that this powerful technology revolutionary and could affect all citizens. This technology creates a strong interest from companies, because of its effectiveness operational and cost reduction offered. However, it leads to a concern regarding the protection of personal information and life private citizens. RFID fits into the category of contactless identification technology hence the name "Radio Frequency Identification" [1]. As well as barcodes, RFID stands the mainly identify objects at a distance and without contact, read multiple objects simultaneously, to establish the amount of information in identifiers greater than barcodes and with more advanced security [2]. RFID finds its applications in most economic sectors include transportation, logistics, industry, buildings and public works, food, health. However, history shows that any technology that can increase the comfort of the everyday life of citizens, managed to win despite any inconvenience that may arise. Services for people with reduced mobility have been a permanent feature of research and innovation for safety information and guidance of sensory impaired people and especially the blind and visually impaired (BVI), which are the most disabled with information based mainly on the display and visual information [3]. On this theme, two projects have been successfully supported, BIOVAM then RAMPE. In [4],the author present the project BIOVAM was centered on an analysis of information needs and orientation of blind or visually impaired access area multimodal networks rail (metro and train) using infrared technology. RAMPE project [5] analysis needs location information and guidance on the bus mode for which the difficulties are extensive and intense, rich for a problem-based hubs and network surfaces (bus and tram). Continuity, our system based on RFID technology continues to approach services, initiated by BIOVAM and RAMPE, specifying, developing and evaluating finally, technology choices for an information system to the properties of both bearer and transferable innovations for new services for all. This paper is divided into two parts outlining the steps and key points of the design of a passive UHF RFID antenna to resonance frequency of 868MHz, which is dedicated to identifying the bus as well as the implementation of the control system electronic in the second part. Finally, we conclude our paper and we suggest some perspectives. II.THE PROPOSED SOLUTION The use of public transport is for the visually impaired population (Not Psychic and visually impaired) a relatively complex task to perform, which often leads to stress and expenditure of energy. Analysis of movement strategies for blind people and the diversity of situations they face during these trips allowed us to identify their needs and define use cases for the application specifications. We describe these requirements in terms of composition and implementation of hardware, applications and interface command / control / communication. Fig. 1. General architecture of the system.
