Abstract
(EN)
A hybrid wireless network and a working method. The hybrid wireless network comprises an antenna module, a first radio frequency switch array, a matching impedance module, a backscatter impedance module, a second radio frequency switch array, a data collection module, an energy collection module, a data transmission module, an energy storage unit, a single chip microcomputer, and a protection circuit module. Radio frequency energy collection and backscatter communication functions are integrated into the same system. By controlling the switching of the radio frequency switch arrays, the hybrid wireless network can dynamically change its working mode, so that the flexibility of a system is greatly increased, and thus, the system can be applied to more different application scenarios. The hybrid wireless network and the working method implement self-sustainable supply of energy by means of a radio frequency energy collection function, and greatly reduce energy consumption during a communication process by means of backscatter communication.

L'invention concerne un réseau sans fil hybride et un procédé de travail. Le réseau sans fil hybride comprend un module d'antenne, un premier réseau de commutateurs de radiofréquence, un module d'impédance de mise en correspondance, un module d'impédance de rétrodiffusion, un second réseau de commutateurs de radiofréquence, un module de collecte de données, un module de collecte d'énergie, un module de transmission de données, une unité de stockage d'énergie, un micro-ordinateur monopuce, et un module de circuit de protection. Des fonctions de collecte d'énergie de radiofréquence et de communication de rétrodiffusion sont intégrées dans le même système. Par la commande de la commutation des réseaux de commutateurs de radiofréquence, le réseau sans fil hybride peut changer dynamiquement son mode de fonctionnement, de telle sorte que la flexibilité d'un système est considérablement augmentée, et ainsi, le système peut être appliqué à davantage de scénarios d'application différents. Le réseau sans fil hybride et le procédé de travail mettent en œuvre une alimentation autonome en énergie au moyen d'une fonction de collecte d'énergie de radiofréquence, et réduisent considérablement la consommation d'énergie pendant un processus de communication au moyen d'une communication par rétrodiffusion.
