step S1: dividing all data lines in a data interface into a first group of data lines and a second group of data lines which are independent of each other in advance;
the specific number of the data lines in the first group of data lines and the second group of data lines may be set autonomously, and the sum of the number of the data lines in the two groups of data lines may be the total number of the data lines in the data interface.
Step S2: sending the image data of the target object to a data receiving end through a first group of data lines;
specifically, in the embodiment of the present invention, the first group of data lines are divided from the unique data interface, and then the image data of the target object is sent to the data receiving end through the first group of data lines, so that the data receiving end can receive continuous image data through the first group of data lines, and thus, the data receiving end can directly store the image data into a complete image of one frame according to the physical receiving sequence, which is convenient for analyzing and processing the image subsequently.
Step S3: sending the temperature distribution data of the target object to a data receiving end through a second group of data lines;
and the sum of the data lines of the first group of data lines and the second group of data lines is the total number of the data lines of the data interface.
Specifically, it should be noted that the first group of data lines should not intersect with the second group of data lines, so that it can be ensured that each group of data lines can exclusively transmit data corresponding to itself, and uniformity of data types transmitted by each group of data lines is ensured, so that the data receiving end can receive continuous data of one type through each group of data lines.
The temperature distribution data of the target object are sent to the data receiving end through the second group of data lines, so that the data can be ensured to be received and continuously received, and the received temperature distribution data can be directly stored into a complete temperature distribution array according to a physical receiving sequence for subsequent processing.
Specifically, the sum of the data lines of the first group of data lines and the second group of data lines is the total number of the data lines of the data interface, so that all the data lines in the data interface can be fully utilized, the utilization rate of the data interface is improved, and the data transmission rate is improved.
Of course, the sum of the data lines of the first group of data lines and the second group of data lines may also be less than the total number of data lines of the data interface, which is not limited herein in the embodiments of the present invention.
The invention provides a data transmission method of an infrared movement, because the invention can continuously transmit image data by using a first group of data lines in a data interface, the second group of data lines in the data interface can be used for continuously transmitting the temperature distribution data, so that the data receiving end can directly store the image data received from the first group of data lines into a complete image of the target object according to a physical receiving sequence, and can also store the temperature distribution data received from the second group of data lines into a complete temperature distribution array of the target object according to the physical receiving sequence.
