Embodiment 1

[0025] A physical isolation data transmission method based on infrared data transmission, comprising the steps of:

[0026] a. Build the data sending end and the data receiving end. Both the data sending end and the data receiving end are composed of a power supply module, a peripheral module, an infrared transceiver module, a single-chip microcomputer main control module and a data transmission device. The data transmission device of the data sending end is a data transmission device. The sending device, the data transmission device at the data receiving end is the data receiving device;

[0027] b. The single-chip main control module at the data sending end reads the data obtained from the USB port or serial port through the GPIO port, and after processing according to user needs, sends it to the infrared transceiver module through the UART port;

[0028] c. The infrared transceiver at the data sending end is connected to the data sending interface, and the data is sent out ...

Embodiment 2

[0033] On the basis of Embodiment 1, the power supply module stabilizes and filters the 5V voltage input from the USB or external power supply and steps it down to a 3.3V voltage to supply power to the MCU main control module, peripheral modules and infrared transceiver modules.

Embodiment 3

[0035] On the basis of Embodiment 1, the peripheral module marks the working state of the device, and the working state includes power supply state, data sending and receiving state and switch state. For example, the power supply light indicates whether the power supply is normal, the data sending and receiving light reminds the user whether the data is being sent and received by continuously flashing, and the button switches and resets the device and other functions.

Abstract

The invention discloses a physical isolation data transmission method based on infrared data transmission, belongs to the technical field of data transmission technologies, solves the problem that data information is easy to steal due to the fact that data transmission equipment adopts a physical medium for data transmission in the prior art, and comprises the following steps: a, constructing a data transmitting end and a data receiving end; b, a single-chip microcomputer main control module of the data sending end reads in the data, processes the data and sends the data to an infrared transceiver module; c, an infrared transceiver of the data sending end sends the data outwards in an infrared data form; d, when an infrared data signal appears at the data sending end, an infrared transceiver of the data receiving end collects the data sent by the data sending end and transmits the data to a single chip microcomputer main control module of the data receiving end; e, the data receiving equipment collects the infrared data signals to the single chip microcomputer master control module through the infrared transceiver, and the infrared data signals are sent to a specified storage address after being processed. The method is used for single data transmission and the like of confidential places and confidential equipment.

Description

technical field [0001] The invention belongs to the technical field of information transmission, and in particular relates to a physical isolation data transmission method based on infrared data transmission. Background technique [0002] Data transmission is to transmit data from the data source to the data terminal through one or more data links according to certain regulations. Its main function is to realize the information transmission and exchange between points. A good data transmission method can improve the real-time and reliability of data transmission. [0003] The data transmission part plays an important role in the whole system, which is equivalent to the nerves of the human body transmitting signals to various parts of the body. How to efficiently, accurately and timely transmit the digital information collected by the acquisition module is an important issue. [0004] A data transmission system usually consists of a transmission channel and data circuit term...
