An optoelectronic backhaul partition interaction system that interacts with signal sources in each sub-network

Abstract

The present invention relates to an optoelectronic backhaul partition interaction system and an interaction method for interacting with signal sources of each subnet. The serial-to-network equipment and forwarding equipment in each subnet; the network-to-optical equipment and the optical-to-serial equipment are connected by one-way optical fiber, the optical-to-serial equipment and the serial-to-network equipment are connected by a one-way serial cable, and the forwarding equipment is used The method is to receive the control command sent by the SSN device through the target subnet, and control the target signal source through the target subnet according to the control command sent by the SSN device. The present invention can prevent others from using components in the interactive device as information carriers to carry out reverse transmission of information by means of light or electricity, thereby improving the security of information interaction, especially improving the security of information interaction in each subnet Sex, avoiding the flow of information between subnets or mutual theft during the interaction process.

Description

Technical field [0001] The present invention relates to an interactive system signal source and interaction methods, in particular, it relates to a photoelectric return blocking interaction system and method for interacting in each sub-signal source. Background technique [0002] In some surveillance, often require the transfer of a number of inter-network monitoring images, such as figure 1 , In which three groups of three dashed box monitoring apparatus (such as a network camera), which are located in subnet 1, Subnet 2, the subnet 3 (e.g. figure 1 Shown), a subnet, subnet Subnet between 2 and 3 because of the different sectors belonging, for security reasons the dashed box, is prohibited information between subnets occurs each flow sequence, i.e., the need to prevent subnets content monitoring device 1 flows into the sub-network 2 monitoring device, or monitoring device 1 of the subnetwork affect the operation of the monitoring device 2 subnet. Thus, marked in the figure by "n...

Problems solved by technology

This operation mode that requires frequent connection and disconnection of the network seriously reduces the rate of information acquisition, affects the efficiency of interaction, and increases the cost of personnel operations

In addition, there is also a possibility that other people use electrical signals to use the components used in the above cross-network transfer process, such as connecting lines, as information carriers to steal relevant information
