La présente invention se rapporte à un système de production autonome d'énergie permettant de surveiller l'ouverture/la fermeture d'une soupape de gaz de manière sans fil et à distance, le système effectuant une production autonome d'énergie en fonction des manœuvres d'ouverture et de fermeture de la soupape à gaz, afin de surveiller immédiatement les états d'ouverture et de fermeture de la soupape à gaz de manière sans fil, ce qui permet d'améliorer la sécurité au moyen d'une réponse rapide. Le système comprend : un détecteur d'ouverture et de fermeture d'une soupape de gaz à production autonome d'énergie, apte à une production autonome d'énergie, et relié à un tuyau de gaz et actionné par l'intermédiaire d'une production autonome d'énergie en fonction de l'ouverture et de la fermeture de la soupape de gaz ; une unité de réception qui reçoit les états d'ouverture et de fermeture de la soupape de gaz en fonction du fonctionnement du détecteur d'ouverture et de fermeture de la soupape de gaz à production autonome d'énergie, par l'intermédiaire d'une communication sans fil, et qui surveille les états ; et une unité d'application qui active une notification en temps réel d'un signal transféré par l'intermédiaire de l'unité de réception. Le détecteur d'ouverture et de fermeture de la soupape de gaz à production autonome d'énergie comprend : une unité de support de corps reliée au tuyau de gaz ; un ensemble corps relié à un levier de soupape sur la partie supérieure de l'unité de support de corps ; une unité d'ouverture et de fermeture de soupape reliée à l'unité de support de corps par l'intermédiaire de l'ensemble corps afin de permettre l'ouverture et la fermeture du tuyau de gaz au moyen d'une rotation ; un rotateur monté dans l'ensemble corps et fonctionnant selon les fonctionnements d'ouverture et de fermeture de l'unité d'ouverture et de fermeture de soupape ; et une unité de détection de production autonome d'énergie étanche à la poussière et à l'eau, montée dans l'ensemble corps et effectuant une production autonome d'énergie en fonction de la rotation du rotateur.
