Problems solved by technology

After the data packet sent by the gateway network delay arrives at the server, the serial number of the data packet in the server will be disturbed, and it is impossible to judge whether the data packet is repeated
[0008] When the above three situations occur, the size of the serial number of the data packet can no longer be used to judge whether the data packet is a duplicate data packet or a new data packet

Abstract

The invention discloses an LPWAN technology-based redundant data filtering method for a network communication management platform. The method comprises the steps of receiving a data package through aserver, wherein the data package comprises a low-byte first serial number forming a complete serial number of the data package, and a check code, and the check code is obtained by calculation of the complete serial number of the data package; and when the first serial number of the currently received data package is smaller than a first serial number of a previously received data package, if the check code of the currently received data package is different from a check code obtained according to node restarting calculation and a check code obtained according to high-byte calculation of the data package during node carry, filtering the currently received data package as a repeated data package sent by delay. Through the filtering method, whether the received data package is repeated or notcan be accurately judged, so that the repeated data package is filtered; and meanwhile, a new data package is not filtered mistakenly.

Description

technical field [0001] The present application relates to the field of Internet technology, in particular to a method for filtering redundant data on a network communication management platform based on LPWAN technology. Background technique [0002] In the field of Internet communication technology, there is a many-to-one relationship between nodes and gateways, and between gateways and servers. Therefore, the data packets of nodes may be received by multiple gateways during the transmission process, and then each gateway transmits the data packets to the same server. At this time, the server will receive multiple sets of repeated data packets, and the server will receive multiple sets of The repeated data packets are sent to the application side. Therefore, the repeated sending and processing of data packets is caused, which increases the processing time and running memory of the server. [0003] Existing methods for filtering duplicate data packets such as figure 1 As ...
