Abstract
L'invention concerne un système et un procédé d'alarme intégrés à une station de sécurité publique mobile et à un robot. Le système est caractérisé en ce que : lorsqu'une station de contrôle de qualité d'eau dans une ville présente une qualité d'eau sur site chutant en dessous d'une norme, une plateforme d'alarme de qualité d'eau (101) peut calculer une distance linéaire entre les informations de position de chacune des stations de sécurité publique mobiles enregistrées dans la ville et les informations de position de ladite station de contrôle de qualité d'eau ; s'il est déterminé qu'il existe une station de sécurité publique mobile cible (102) dont la distance linéaire par rapport aux informations de position de ladite station de contrôle de qualité d'eau est inférieure à un seuil spécifié, des informations d'alarme de qualité d'eau incluant les informations de position de ladite station de contrôle de qualité d'eau ayant une qualité d'eau sur site en dessous de la norme sont envoyées à la station de sécurité publique mobile cible (102) et à un premier serveur (200) au moyen de l'internet des objets ; et la station de sécurité publique mobile cible (102) émet les informations d'alarme de qualité d'eau. Le système permet une alarme opportune liée à la qualité d'eau en dessous d'une norme, garantissant ainsi une utilisation sûre de l'eau dans une ville. La présente invention réalise une gestion financière sur un compte de gestion financière correspondant à un identifiant d'utilisateur correspondant d'un robot cible, fournissant par conséquent à un robot une incitation à participer à une activité d'alarme liée à la qualité d'eau chutant en dessous d'une norme.
