7. The block chain based cloud-edge cooperative parking management time-based charging method according to claim 6, further comprising a charging rule information updating method comprising:
the central platform stores the charging rule information of each parking lot management subsystem and sends the charging rule information to the corresponding edge node to calculate the parking fee;
and after the charging rule information is modified based on an external instruction, the corresponding edge nodes are synchronously updated through the central platform.
8. The block chain-based cloud-edge cooperative parking management time-based charging method according to claim 6 or 7, wherein the block body of the block chain further includes charging rule information adopted by each charging record corresponding to the edge node.
9. The method for cloud-edge cooperative parking management time-based charging based on block chains according to claim 6 or 7, wherein the information contained in the block main bodies of the block chains is packaged according to three levels of city-region-parking lot.
10. A parking guidance method based on cloud-edge cooperative parking management, characterized in that, based on the block-chain-based cloud-edge cooperative parking management time-based charging system of any one of claims 2 to 5, the parking guidance method comprises:
the central platform acquires the number of vehicles entering the parking lot and the number of vehicles exiting the parking lot corresponding to the parking lot in real time through edge nodes of each parking lot management subsystem, and sends the obtained numbers to the parking guidance module;
and the parking guidance module updates the information of the remaining parking spaces of the corresponding parking lot in real time based on the number of vehicles driving into the parking lot and the number of vehicles driving out of the parking lot.
