Charging pile data storage method and storage device based on peer-to-peer network

Abstract

The present invention relates to a peer-to-peer network-based charging pile data storage method, overcoming defects of the prior art. The method comprises a first step that a charging pile generates service data, the charging pile adds a time stamp in the service data, so as to form charging operation data, and node data is broadcasted globally; a second step that a node in the network receives broadcast information, the node in the network receives a data verification request, and then broadcasts its own determining condition, a quantity of online nodes in the network is determined, and if the quantity of the online nodes in the network exceeds a preset quantity of online nodes in the network, it is determined that the charging operation data is effective; a third step that the charging pile receives information that the charging operation data is effective, performs hash operation on the charging operation data, and then adds the charging operation data into a data link; a fourth step that after the charging operation data is added to the data link successfully, the network node is informed of the successful adding of the charging operation data through broadcasting, and it is determined that the nodes of which the quantity exceeds the preset quantity of nodes at least confirm the successful adding of the charging operation data; and a fifth step that data combination is performed on data link data according to a multi-hash tree structure.

Description

technical field [0001] The invention relates to a charging network operation situation analysis method and device, in particular to a peer-to-peer network-based charging pile data storage method and a storage device thereof. Background technique [0002] With the construction of the charging pile operation platform, especially the construction of large-scale charging stations, the demand for the charging pile network access platform is getting higher and higher. To connect the ordinary charging pile to the operation platform, it first needs to have the ability of remote networking; while charging Even if the pile network fails, the offline charging demand can still be guaranteed. [0003] Relevant teams at home and abroad have made charging equipment with networking functions. The relevant information of the charging equipment will be uploaded to the central server for management, and the system can also send instructions to the equipment as needed; however, since the busin...
