Abstract

The present application provides a method for filtering and detecting a receipt state and a receipt printing device. The method for filtering and detecting a receipt state includes the following steps: continuously sensing the receipt, and outputting data "1" at the moment when the receipt is sensed; Output data "0" at the moment when the receipt is sensed; store the data in a fixed-length window in turn according to the time relationship; perform summation processing on the data falling in the window; compare the value obtained from the summation processing with the set threshold Comparison, if the value obtained by the summation processing is less than the set threshold, it is judged that there is no receipt, otherwise it is judged that there is a receipt; the filter detection method of the receipt state of the present application first digitizes the initial sensing data, and then stores the data in the The summation is performed in a fixed-length window, and the receipt status is judged again, which can not only ensure the judgment accuracy of the receipt status, filter the sliding window, but also reduce the delay time and improve the response time of the output result.

Description

technical field [0001] The present application belongs to the technical field of self-checking channels, and more particularly, relates to a method for filtering and detecting a receipt state and a receipt printing device. Background technique [0002] The self-service inspection channel needs to print the information receipt after the certificate verification is completed. Because of laws and regulations, the receipt needs to be verified in the follow-up process, so passengers need to take the initiative to take the receipt, otherwise the follow-up process will be abnormal. [0003] At present, there are two main ways to use self-service inspection channels on the market. The first method is to make a paper receiving box at the paper outlet of the printer. After the inspection channel is completed, the receipt will be printed and cut, so that the receipt will fall into the box. The screen is displayed as an interface prompt to take away the receipt. After the receipt is dro...
