Cross-network interaction system and cross-network interaction method

Abstract

The invention provides a cross-network interaction system. The cross-network interaction system comprises an interaction computer, first conversion equipment, one-way transmission equipment and secondconversion equipment in each sub-network; the interactive computer is used for sending a control command for one signal source to the first conversion equipment through a network; the first conversion equipment receives the control command, and converts the control command in the network signal form into a proper form suitable for being transmitted to second conversion equipment in a subnet wherethe signal source is located through the one-way transmission equipment, and the control command in the proper form is transmitted to the second conversion equipment through the one-way transmissionequipment; and the second conversion equipment receives the control command in the proper form, converts the control command into a control command in a network signal form again, and sends the control command to the targeted signal source through the subnet so as to control the signal source. According to the invention, real-time and safe calling of the network cameras in the plurality of subnetsand safe interaction of the network cameras can be realized.

Description

technical field [0001] The invention relates to an interaction device and an interaction method, in particular to a cross-network interaction method and system for interacting signal sources in at least two subnets. Background technique [0002] In some monitoring fields, it is often necessary to retrieve some monitoring images across the network, such as figure 1 As shown, the three dotted boxes represent three groups of monitoring equipment (such as network cameras), which are respectively located in subnet 1, subnet 2, and subnet 3 (such as figure 1 As shown in the dotted line box in the middle), because subnet 1, subnet 2 and subnet 3 belong to different departments, for security reasons, it is strictly forbidden for the information between these subnets to flow with each other, that is, it is necessary to prevent the subnet The content of the monitoring device of 1 flows into the monitoring device of subnet 2, or the monitoring device of subnet 1 affects the operation ...

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
