Block chain based charging pile charging transaction communication method and device

Abstract

The invention relates to a block chain based charging pile charging transaction communication method which overcomes the defects of the prior art. The technical scheme is that: a first step, a charging pile node generates a charging transaction, and the charging pile node requests a timestamp server for timestamp information; a second step, the charging pile node performs random hashing on charging transaction information, and adds a timestamp to the charging transaction information and performs block packaging; a third step, the charging pile node having the transaction broadcasts the charging transaction information to the whole network of a charging pile network, and charging pile nodes in the charging pile network update charging transaction block information; a fourth step, a charging pile transaction service gateway regularly updates block chain information to keep the complete block chain information; a fifth step, the charging pile transaction service gateway analyzes the changed block chain charging transaction information, and the block chain charging action information is structuralized and stored in a database; and a sixth step, the charging pile transaction service gateway determines if the block chain charging transaction information is complete or not, and the fourth step is executed again if not.

Description

technical field [0001] The present invention relates to a charging pile charging transaction communication method and device, in particular to a charging pile charging transaction communication method and device based on a block chain. Background technique [0002] The traditional charging pile communication mode mainly uses the TCP / IP protocol to communicate with the central server to realize functions such as status monitoring and charging transactions. The defect of the current IoT communication method is that when the hardware or the network fails, the key communication transaction records are easily tampered with, and the communication pressure on the central server is too high. Once there is a problem with the central server, the charging pile operation network service will be interrupted, and the risk of charging piles connecting to the cloud will also be passed on to the network security of the entire operation platform. Contents of the invention [0003] The purp...
