Problems solved by technology

[0005] At present, network security detection based on traditional firewall functions cannot prevent many unknown attacks, because these security detections are based on the TCP / IP protocol itself, and the protocol itself has loopholes; in addition, firewalls are passive defenses based on blacklists. This gives hackers an opportunity to attack

Abstract

The invention discloses a multi-information-source communication management device based on a security isolation gateway. The multi-information-source communication management device comprises a security data exchange unit, and a circuit controller, an external data processor and an internal data processor which are connected with the security data exchange unit; the external data processor is connected with a plurality of external network ports; the internal data processor is respectively connected with the memory, the Ethernet control panel, the serial port control panel, the maintenance network port and the field programmable gate array expansion port, is connected with the plurality of network ports through the Ethernet control panel, and is connected with the VGA interface and the USBinterface through the serial port control panel; and the circuit controller controls the safe data exchange unit to be connected with the external data processor and the internal data processor. According to the invention, the security gateway between the intranet and the extranet is realized, the data transmission of external data in a network isolation security environment is ensured, and the security of the comprehensive monitoring system is improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit integrated automation systems, and specifically refers to a communication management device for a multi-information source integrated monitoring system based on a security isolation gatekeeper. Background technique [0002] Urban rail transit is an important means of transportation related to public safety. Its safety is very important. Various standards for urban rail transit safety must be provided, and technical safety is a very important part. If the safety of rail transit cannot be guaranteed technically, it will cause great harm to the society. The management of rail transit is now carried out through the Internet. If criminals use the Internet to try to endanger the safety of rail transit, it will cause serious social unrest and turmoil. [0003] At present, the comprehensive monitoring system of urban rail transit is facing a complex environment. The so-called complex environment is ...
