Avec le nombre croissant de crimes et d'accidents dans lesquels des enfants sont impliqués, il existe une demande croissante de dispositifs permettant de garantir la sécurité des enfants en détectant leur emplacement sur le chemin de l'école. Cet article propose un système qui utilise un réseau standard IEEE802.15.4 pour détecter l'emplacement des enfants. Pour surmonter la susceptibilité aux interférences radio provenant des réseaux locaux sans fil à proximité, le multiplexage par répartition en fréquence est appliqué à ce réseau basé sur IEEE802.15.4, afin d'améliorer l'acquisition de données à partir des unités terminales. L'efficacité du système a été testée sur le terrain auprès d'élèves du primaire qui ont utilisé environ 400 unités terminales conformes à la norme IEEE 802.15.4. Une expérience a vérifié que l'utilisation du multiplexage par répartition en fréquence dans un environnement où les interférences radio des réseaux locaux sans fil sont fortes a permis au réseau de doubler le taux de réussite de la communication d'informations à partir des unités terminales par rapport à celle sans multiplexage par répartition en fréquence. Dans l'expérience de détection des arrivées et des départs des élèves du primaire, le taux de détection terminale était de 99 % et le taux de détection terminale sur les itinéraires scolaires désignés était de 90 %. Ces résultats prouvent l’efficacité du système dans la détection des emplacements.

Abstract: With the increasing number of crimes and accidents in which children are becoming involved, there is a growing demand for devices to safeguard children's security by detecting their locations on their way to and from school. This paper proposes a system that uses an IEEE802.15.4-standard network to detect children's locations. To overcome the susceptibility of radio interference from nearby wireless LANs, frequency division multiplexing is applied to this IEEE802.15.4-based network, toward improving data acquisition from terminal units. The effectiveness of the system was field-tested with elementary school students who used about 400 IEEE 802.15.4-compliant terminal units. An experiment verified that the use of frequency division multiplexing in an environment where radio interference by wireless LANs is strong allowed the network to double the success rate of information communication from terminal units relative to that without frequency division multiplexing. In the experiment for detecting elementary schoolers' arrival at and departure from school, the terminal detection rate was 99% and the terminal detection rate on the designated school routes was 90%. These results prove the effectiveness of the system in detecting locations.
