  • Multi-user real-time monitoring page the page displays the current location of all online terminal users, user information, terminal power and terminal positioning mode.
  • the terminal device positioning method and system in the embodiment of the present invention adopts multiple positioning modes such as GPS, WIFI or base station to ensure that when the effective GPS positioning data is not obtained, the positioning data of the terminal device is obtained through other positioning methods such as WIFI or base station, thereby realizing Accurate positioning indoors and outdoors; for non-GPS positioning data, call the third-party coordinate conversion interface for coordinate conversion, and use the timing execution plan to check whether the program is abnormally interrupted, and restart the program in time when the program is abnormally interrupted, avoiding the abnormal interruption due to the program.
  • the coordinate conversion fails, at the same time, the positioning data coordinate conversion is separated from the real-time positioning display.
  • the third-party client requests the location of the terminal user, the execution time of the program is reduced, and the operation efficiency of the third-party client is improved.

Abstract

La présente invention concerne un système et un procédé de positionnement intérieur et extérieur pour un équipement terminal. Le procédé de positionnement comprend les étapes suivantes : étape a, recevoir des données de positionnement d'un équipement terminal ; étape b, déterminer si un mode de positionnement de l'équipement terminal est un mode de positionnement par GPS en fonction des données de positionnement reçues ; si le mode de positionnement de l'équipement terminal n'est pas le mode de positionnement par GPS, convertir les données de positionnement en données de positionnement par GPS, et effectuer l'étape c ; si le mode de positionnement de l'équipement terminal est le mode de positionnement par GPS, effectuer l'étape c ; et étape c, convertir les données de positionnement en coordonnées cartographiques, et afficher les coordonnées cartographiques dans la carte, de façon à positionner l'équipement terminal. Dans le procédé et le système de positionnement, de multiples modes de positionnement, tels que des modes de positionnement GPS, Wi-Fi ou de station de base, sont utilisés, il est garanti que des données de positionnement de l'équipement terminal sont obtenues au moyen d'un Wi-Fi ou d'une station de base si des données de positionnement par GPS valides ne sont pas obtenues, ce qui permet de mettre en œuvre le positionnement intérieur et extérieur précis.
