Abstract

An embodiment of the invention provides a detector, a detecting system and a detecting method. The method includes a synchronous signal transmitting step, namely generating and emitting frame synchronization signals through GPIO; an acquisition and package step; an initialization step, namely generating GPIO interception according to the received frame synchronization signals, performing the initialization and operating a timer to receive data; a data receiving step; a frame interception determination step; a frame interception processing step; an abnormality processing step, namely triggering timer interception, adding one to the value of an abnormality counter and switching off the timer; a detection determination step. According to the embodiment, the manner of matching the frame synchronization signals and the timer interception is adopted, the bank note data abnormalities can be found and counted timely, the data independence of bank notes is high, the data of the next bank note is free of the influence of the abnormality of one bank note, the rate of undetermined bank notes in batches is reduced, and the detecting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of banknote detection, and in particular relates to a banknote checking device, a banknote checking system and a banknote checking method. Background technique [0002] The existing banknote checking device will immediately generate a frame interrupt after receiving the data of a banknote, and initialize some registers of itself, and then start to receive the data of the next banknote. [0003] However, in the process of checking banknotes, banknotes are often duplicated, consecutive, or data cannot be collected, which will cause data loss. Only after the data of the next banknote is filled will the frame be interrupted, which leads to starting from this banknote. All banknote data are abnormal data, which seriously affects the results and efficiency of banknote inspection. Contents of the invention [0004] The purpose of the embodiment of the present invention is to provide a banknote checking device, a...
