Abstract

The application provides a dynamic authority identification method, a dynamic authority identification system, a dynamic authority identification medium and a dynamic authority identification product for a charging pile, and relates to the technical field of cloud coordination. The method comprises the steps of firstly storing a user account and corresponding NFC information in a local storage of a cell charging pile. When a vehicle or a mobile phone approaches, the charging pile performs local identification by the built-in NFC module preferentially. If the matched local NFC information is detected, the system directly invokes an account and starts charging, so that millisecond response and network disconnection availability are realized. If NFC information is not recognized locally or recognition fails, the system automatically switches to a code scanning mode, a user is guided to carry out identity verification through a cloud of a server, and charging is started after verification is passed. The layered verification logic not only meets the quick charging requirement of the high-frequency user, but also guarantees the normal use authority of the temporary user, and effectively balances the verification efficiency and the system compatibility.

Description

Dynamic authority identification method, system, medium and product of charging pile Technical Field The application relates to the technical field of cloud coordination, in particular to a dynamic permission identification method, a system, a medium and a product of a charging pile. Background With popularization of low-carbon trip concepts and rapid increase of electric vehicle conservation quantity, construction of centralized charging facilities in a community has become an important component of an intelligent community. In order to improve user experience and management efficiency, modern charging piles generally integrate the internet of things technology and support a plurality of identity recognition and payment modes such as code scanning, IC card or NFC (near field communication). The NFC technology gradually replaces the traditional coin-in mode due to the characteristics of non-contact, quick response and convenient operation (such as using a mobile phone or a bracelet to directly sense), and becomes an authentication means for high-frequency use by users. In the existing charging pile technical architecture, authority identification mainly depends on an end-cloud interaction mode. Specifically, when a user touches a charging pile through NFC equipment, the charging pile uploads the read card number or equipment information to a cloud server, the server inquires the balance and the authority state of the account in a database, and after verification, an opening instruction is issued to the charging pile. In order to improve the response speed, part of the prior art schemes can locally cache a white list, or is designed into logic of sensing and starting, namely, once the NFC module detects legal identity tags, a relay is immediately closed to supply power, so that the waiting time of a user is reduced. However, the above prior art has significant drawbacks in practical applications. The cloud verification mode is limited by a network environment, communication timeout easily occurs in an underground garage or a signal shielding area, so that charging cannot be performed, and the local storage verification is fast in response, but a conventional electric vehicle charging pile usually adopts a low-performance MCU, so that the storage space is extremely limited, and the storage capacity is too small, so that the situation that the number of users is large is inconvenient. Therefore, a charging pile dynamic permission identification method which combines the verification response speed and the storage resource optimization is needed. Disclosure of Invention The application provides a dynamic authority identification method, a system, a medium and a product of a charging pile, which are used for optimizing the response efficiency and the storage resource utilization rate of NFC authority identification of the charging pile in a community and improving the stability of charging service of an intelligent community. In a first aspect, the present application provides a method for identifying dynamic rights of a charging pile, applied to a charging pile management system, the method including locally storing user account information through a plurality of charging piles disposed in a cell; the method comprises the steps of extracting NFC information in user account information and storing the NFC information in a local database of a cell, acquiring target NFC information through an NFC identification module arranged in a charging pile when a target electric vehicle or a target mobile phone enters a preset NFC detection range, detecting whether NFC information corresponding to the target NFC information exists in the local database of the cell, accessing a corresponding user account and starting charging and broadcasting a charging prompt if the NFC information corresponding to the target NFC information exists, and carrying out server cloud verification after the target user scans codes or not identifying NFC corresponding to the target NFC information, and broadcasting a charging prompt after the target user passes through the server cloud verification. By adopting the technical scheme, the charging pile locally stores the user account and NFC information and links with the local database of the cell, the user performs local verification preferentially when NFC induction is performed, cloud communication is not needed, the problem of communication timeout of signal blind areas such as underground garages is directly avoided, verification response speed is greatly improved, meanwhile, cloud code scanning verification is triggered only when the local verification does not pass or does not recognize NFC, and a double-layer verification mechanism of 'local priority and cloud spam' is formed. The layered verification logic not only meets the quick charging requirement of the high-frequency user, but also guarantees the normal use authority of the temporary user, effectively balances the verification efficie
