Network monitoring filtering system based on hardware control

Abstract

The invention discloses a network monitoring filtering system based on hardware control. The network monitoring filtering system comprises a PC unit and a monitoring filtering unit, the PC unit and the monitoring filtering unit transfer data through a serial bus, and the PC unit comprises a password setting unit, a monitoring filtering processing unit, a network card control unit and an instruction control unit which are connected two by two. The monitoring filtering unit comprises a single-chip microcomputer and a USB / serial-port transition unit. The single-chip microcomputer is a core processing module of the monitoring filtering unit, and the single-chip microcomputer comprises a password memory and an input unit; and the password memory is used to save a system password, and the input unit is used to input an instruction to the instruction control unit of the PC unit. The network monitoring filtering system can effectively manage network usage and is also convenient to use by teenager parents; a role of the network monitoring filtering system can be effectively played, a green network environment can be restored, and teenager users can obtain knowledge from a network but are not interfered by bad information.

Description

technical field [0001] The invention relates to a network monitoring and filtering system based on hardware control. Background technique [0002] Internet technology has brought revolutionary changes to information dissemination, for example, the "decentralization" of the network, which is open to everyone, has unlimited information sources, and everyone can be both a user and a provider of information . Moreover, the network is also interactive, and users can independently choose and control the information they receive. [0003] These characteristics have broken through all previous forms of communication and provided great convenience for the diversification of information and the expansion of free speech space. However, the network requires a relatively free connection with the outside world, so it is more vulnerable to threats from many aspects, such as physical threats, threats caused by system vulnerabilities, identity authentication threats, cable connection threa...

AI Technical Summary

Problems solved by technology

[0005] At present, the technology in this area is relatively immature, and there are problems such as low use efficiency. For example, many parents of students want to use the network filtering system to control their children's network use, but as teenagers themselves, due to self-control Insufficient power, and can easily avoid or cancel the use of software-related software, so parents cannot achieve the purpose of control, and at the same time lose the real meaning of using this type of system
