Data collection method and data collection device

Abstract

The invention is suitable for the field of data acquisition, and provides a data acquisition method and data acquisition equipment. The data acquisition method comprises the following steps: controlling a first data carrier and a second data carrier to move along a specified direction in sequence from a preset position, wherein a first distance is kept between the first data carrier and the second carrier; if the first distance is smaller than a preset distance, acquiring data recorded by the second data carrier when a second time reaches, a first time is the time when acquisition of the data recorded by the first data carrier is finished at, the second time is time obtained by subtracting a first adjusting time from the sum of the first time and a preset time, the preset time is determined according to the preset distance, and the first adjusting time is determined according to the distance difference between the preset distance and the first distance. By adopting the data acquisition method and the data acquisition equipment, the time for reading the data of the second data carrier can be adjusted adaptively and automatically, and the data of the second data carrier is read fully.

Description

technical field [0001] The invention belongs to the field of data collection, and in particular relates to a data collection method and data collection equipment. Background technique [0002] With the progress of the times, various bills have been widely used, especially the application of financial bills (such as banknotes), making world trade more convenient and faster. While bills are widely used, the problem of information security arises. [0003] In order to realize the safe use of bills, the commonly used means of verifying the authenticity of bills is to load bill data and authenticity verification data in the bills. When checking the authenticity of the bill, the image, magnetism, thickness and other signals in the bill are collected to obtain an analog signal, and the analog signal is converted into a digital signal to verify the authenticity using a preset algorithm. However, the current bill verification devices all detect the information of the interval bills...

AI Technical Summary

Problems solved by technology

However, the current bill verification devices all detect the information of the interval bills respectively at equal time intervals; After completing the information of the previous ticket, the time interval cannot be shortened adaptively to read the information of the next ticket in advance, resulting in only partial reading of the information of the next ticket
