A network data recording system and its network data recording method

Abstract

The invention discloses a network data recording system, comprising: a plurality of remote measurement and control units, a convergence routing device connected to the plurality of remote measurement and control units and providing remote network access functions for the remote measurement and control units and a convergence A user application for monitoring and managing routing equipment, a network control server and a data recording server. The network control server includes a remote measurement and control unit network control server, a convergence routing equipment network control server and a user application network control server. The measurement and control unit data recording server, the aggregation routing device data recording server, and the user application data recording server. The invention proposes a data recording system based on a distributed server network of a network management server and a data recording server, thereby effectively reducing the server's centralized load and facilitating group management; and proposes the use of dynamic key technology to improve the system data security.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a network data recording system and a network data recording method for sensors, telemetry and telecontrol equipment to record data on the network. Background technique [0002] In wireless sensor networks, telemetry systems, and telecontrol systems, users can obtain the status and collected data of remote measurement and control units, and control them. There are usually two solutions: based on direct point-to-point or point-to-multipoint communication systems or Communication system based on web server. figure 1 It is a network architecture diagram of a direct point-to-point or point-to-multipoint communication system. Usually, a dedicated communication network or short message is used to establish a direct communication channel between the user and the remote measurement and control unit, and the remote measurement and control unit directly sends the status and collected data...

AI Technical Summary

Problems solved by technology

For example, using the same server (including its backup server) to manage all remote measurement and control units will overload the server and affect network performance; another example, if user identities are stolen, it may cause information leakage and affect data security
