Remote information safety transmission and control system

Abstract

The invention discloses a bandwidth network resource realizing remote information safe transfer and control system, which is composed of lead end device, center server, rear end device and bench client end device, wherein the lead end device is installed in different places, which collects different video information to convert video information into digital signal with software compression technique; the lead end device connects data bank information with different information of non-public net; lead end device links up common PSTN telephone network; the lead end device connects the center server through ADSL bandwidth network, which uses INTERNET internet to transfer various kinds of information and control orders; the center server is used for receiving control order from client end, which controls lead end device through INTERNET internet and receives kinds of information from the lead end device through INTERNET internet; the rear end device is installed between center server and client end device, which convers video information from lead end device which is received by center server into video information in analog signal form with video information; the convered information is sent to the client end device.

Description

technical field [0001] The present invention relates to a transmission and control system capable of realizing long-distance secure transmission of information. More specifically, the present invention relates to a transmission and control system capable of realizing long-distance secure transmission of information without using a private network and only using existing network resources. Control System. Background technique [0002] Since the rise of the Internet, people's ideal of long-distance information exchange has been realized. Moreover, with the rapid development of information technology today, the main means for people to obtain remote information is through the Internet. like figure 1 As shown, when the person at point B wants to obtain information (such as video signals or data in the database) at point A that is far away, the person at point B only needs to send a transmission data message to the person / equipment at point A. Instructions, after the equipment...

AI Technical Summary

Problems solved by technology

Since only digital signals can be transmitted on the Internet, the devices at points A and B need to install hardware video compression / decompression cards to perform analog-to-digital and digital-to-analog conversion on video signals, so as to realize video transmission through the Internet. The transmission of information, which also virtually increases the cost of the user's hardware equipment
