Description

Charging pile control method and system Technical Field The application relates to the field of digital information transmission, in particular to a charging pile control method and system. Background As the electric vehicle industry evolves, the charging infrastructure becomes a key complement to it, and its quality of service and user experience become critical. In the process of supplementing energy to the vehicle by using the charging pile, a user needs to timely and accurately acquire charging state information, such as whether charging is completed, whether abnormal interruption occurs or not, so as to reasonably arrange personal time and timely move the vehicle, and avoid resource occupation and unnecessary cost. In related technology, a notification method based on cloud event triggering is provided. The charging pile reports key events in the charging process, such as charging completion or charging interruption, to the cloud server in real time. After receiving the key event, the cloud server sends a push notification to a designated APP on the mobile terminal of the user through the application server so as to inform the user of the state change of the current charging pile. The cloud terminal is used as a core for information transfer and distribution, so that remote notification of the charging state is realized. However, as the charging scenario becomes increasingly complex, the user may be active in areas where network signals are unstable, such as parking lots, malls, or inside buildings, during the waiting period for charging. When the charging state pushing is performed in the related art, if the user is just in the network signal blind area at this time, the mobile terminal cannot timely receive the pushing notification, so that the user cannot know the state that the charging is completed at the first time, and the user can possibly generate unnecessary extra cost due to failure to timely return to move the vehicle, so that the overall experience of the charging service can be influenced. Disclosure of Invention The application provides a charging pile control method and a charging pile control system, which are used for guaranteeing effective access of charging state information in a network poor scene of a user terminal and avoiding economic loss of a user caused by information delay.

In the embodiment, the charging pile control system establishes a local timing notification task at the user terminal, and transfers a trigger mechanism for completing charging from the cloud to the terminal local, so that the problem that notification cannot be reached due to network problems is solved, meanwhile, the accuracy of the local timing task is ensured by dynamically calculating and sending the corrected power-off time in the charging process, and efficient and reliable access of charging state information under a weak network environment is realized. In combination with some embodiments of the first aspect, in some embodiments, after the step of sending an initial power-off time to the user terminal, so that the user terminal configures a local timing notification task based on the initial power-off time to generate charging completion prompt information when the initial power-off time arrives, the method further includes receiving positioning coordinate data and network signal strength reported by the user terminal, calculating network offline probability of the user terminal in a preset time period before triggering the local timing notification task based on the positioning coordinate data and the network signal strength, determining that the network offline probability is greater than a preset probability threshold and a data synchronization time before the preset time period when the network offline probability exceeds the preset probability threshold, acquiring real-time charging information when the data synchronization time, calculating corresponding corr
