Problems solved by technology

[0003] Aiming at the characteristics and disadvantages of traditional one-way transmission of images, without changing the physical isolation and one-way transmission characteristics, and with the main goal of solving the problems of transmission rate and decoding pressure, the present invention combines the original high-speed camera + server to take pictures The combination of decoding becomes a multi-channel computing pre-decoding module, which completes the work of image capture and image decoding, and truly realizes that the burden of decoding calculations is distributed to multiple pre-modules, thereby reducing the performance load of the receiving end of the intranet. Also greatly improved the overall transfer rate

Embodiment Construction

[0011] Describe the present invention below in conjunction with specific embodiment:

[0012] In this embodiment, 200KB of data is taken as an example, the coded image is defined as a 30-version QR code image, the inclusion rate of a single QR code image is defined as 1560 bytes, and 8-channel transmission is configured:

[0013] 101. After receiving the 200KB sample, the sending end of the system divides the sample into data blocks of 1500 bytes in sequence, and encodes the description information and the data content of the blocks into a QR code image;

[0014] 102. The image synthesis module at the sending end sequentially takes out 8 images from the encoded two-dimensional code queue, splices the eight images into a large image, and displays it on the monitor, and forms 8 two-dimensional codes on the monitor for fast playback and display Effect, the playback effect is 8 times that of the single-channel case;

[0015] 103. The receiving end is connected to 8 FPGA decoding ...

Abstract

The invention provides a multi-channel efficient image one-way transmission system based on calculation preposition. The sending end divides the sent data into fixed sizes and encodes the data contentinto an image; an image synthesis module of the sending end splices the N images into a large image in sequence according to the number N of channels of the current system and conducts sequential play; the receiving end is connected with N decoding FPGA modules with pre-calculation, and comprises a lens and a decoding processor, and the decoding modules are in one-to-one correspondence with the image positions; and a receiving end reads the decoded data of the N decoding modules through a serial port and completes data merging operation. The system is based on a plurality of decoding channelsof calculation preposition, is different from traditional image single-channel and server decoding, greatly improves the equipment transmission rate, reduces the performance load of the receiving end, and achieves a more efficient image one-way transmission system.

Description

technical field [0001] The invention belongs to the field of information security isolation transmission, and provides a multi-channel high-efficiency image one-way transmission system based on pre-computing, which is suitable for scenes with low transmission rate and heavy load of traditional image systems, and provides a safer, more reliable and more efficient one-way image transmission system. transmission. Background technique [0002] As a cross-network transmission system, one-way image transmission is widely used in industries with confidentiality requirements. It has physical isolation characteristics and complies with relevant confidentiality regulations, which solves the user's demand for one-way data transmission between isolated networks. However, the traditional one-way image transmission system also has certain limitations and deficiencies according to its own working principle: In terms of transmission rate, relying on a single-channel high-speed camera to cap...
