Embodiment 1

[0040] figure 1 It is a flowchart of a data transmission method provided by Embodiment 1 of the present invention. This embodiment can be applied to an intranet server, and the method can be executed by a data transmission device. Specifically, refer to figure 2 , figure 2 It is a schematic diagram of the system architecture based on data transmission. Intranet server 220 is connected to intranet terminal 210 and serial port display screen 230 respectively. When intranet terminal 210 uploads data to intranet server 220, intranet server 220 Types are processed respectively, and the processed data are transmitted to the serial display screen 230 by the serial port line or the USB line, and are displayed by the serial port display screen 230. At this time, the image acquisition device 240 collects the image on the serial port display screen 230, and collects The image is transmitted to the external network server 250, identified by the external network server 250, and finall...

Embodiment 2

[0049] image 3 The flow chart of a data transmission method provided by Embodiment 2 of the present invention is embodied on the basis of the above-mentioned embodiments. When the data is text data, the data transmission method specifically includes the following steps:

[0050] S210. Receive data sent by the intranet terminal.

[0051] S220. Generate an information two-dimensional code image according to the attribute information of the data, and display the information two-dimensional code image on the serial port display screen.

[0052] Wherein, the attribute information includes: text path, text size, text read and write attributes, text access time and text modification time. The information two-dimensional code image can be understood as a two-dimensional code image containing text data attribute information. Specifically, the text path is used to identify the path where the text content is currently stored, so as to find the corresponding text content according to t...

Embodiment 3

[0084] Figure 5 The flow chart of a data transmission method provided by Embodiment 3 of the present invention is applied to an external network server, and the external network server is respectively connected to an external network terminal and an image acquisition device, and the image acquisition device collects the two-dimensional code image on the serial display screen , and transmit the collected two-dimensional code image to the external network server, the external network server analyzes the obtained two-dimensional code image, obtains the original data, and sends it to the external network terminal. Specifically, the method includes:

[0085] S310. Acquire the two-dimensional code image captured by the image acquisition device at a set time interval.

[0086] Wherein, the two-dimensional code image is displayed on a serial display screen connected to the intranet server. Specifically, the image acquisition device can be a device that can collect images such as a ...

Abstract

Embodiments of the invention disclose a data transmission method and device, a server and a computer storage medium. The method comprises steps of partitioning data sent by an intranet terminal and acquiring at least one data slice, and generating a slice two-dimensional code image of the data slice, wherein the data is text data or TCP data; and showing the slice two-dimensional code image on a serial port display screen in sequence. Through adoption of the method, the data can be transmitted in one way in a form of a two-dimensional code image, so that information is not disclosed, and the method is simple and convenient, and guarantees information consistency and real-time performance.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data transmission, and in particular, to a data transmission method, device, server, and computer storage medium. Background technique [0002] With the development of technology, it is very common to exchange information between systems to obtain the required information or resources. For the government or enterprises that pay special attention to information security, it is often required to isolate the internal network system from the external network system, and only allow A small amount of information is transmitted to the external network system. Traditional data transmission mostly uses U disks or one-time read-write CDs, which cannot obtain data in real time, and there are certain security risks in the transmission process, which is very inconvenient. Contents of the invention [0003] The invention provides a data transmission method, device, server and computer storag...
