Flaky medium processing system and method for detecting real-time position of flaky medium

Abstract

The invention relates to a flaky medium processing system and a method for detecting the real-time position of flaky medium. Multiple detection positions are arranged in a medium transfer channel of the flaky medium processing system, and one position sensor is arranged at each detection position for detecting the arrival and departure events of the flaky medium in the detection position; and the flaky medium processing system and the method are characterized in that the position sensor at the first detection position along the movement direction of the flaky medium is provided with at least three scattered detection points, each detection point outputs an independent output signal, and each detection point is configured with two counters for obtaining the time attribute of the output signal of the detection point; and the position sensor at each of other detection positions is configured with one counter for obtaining the time attribute of the output signal of the common position sensor.

Description

technical field [0001] The invention relates to the automatic conveying control technology of sheet media, in particular to a processing system which needs to continuously classify the sheet media and store them in predetermined positions and a method for monitoring the real-time position of the sheet media. Background technique [0002] A processing system that automatically and continuously classifies sheet media and stores them in a predetermined location, referred to as a sheet media processing system. For the convenience of description, it is assumed that there is a sheet medium processing system as follows, which includes (a) a built-in main controller for implementing automatic control of each component of the system; (b) a sheet medium conveying channel with branches; ( c) Multiple places for storing sheet media (sheet media storage); (d) Parts for sorting sheet media, such as banknote validators; (e) Multiple sensors for detecting the position of sheet media. (f) M...

AI Technical Summary

Problems solved by technology

[0023] Disadvantages: The position sensor occupies a large space, which makes the entire sheet medium processing system larger; due to the large number of sensors and complicated wiring, it is not conducive to improving reliability; at the same time, it is expensive

[0032] (1) It is difficult to determine the optimal filtering parameters, and when the shape of the sheet medium changes greatly, the filtering parameters need to be re-determined

[0033] (2) The position detection accuracy of sheet media is not high

Existing methods can accurately detect the arrival time of sheet media, but cannot accurately detect the departure time of sheet media

[0034] (3) There is a large delay in the signal reflecting the real-time position of the sheet medium, which is not conducive to real-time control; at the same time, the filtering algorithm needs to frequently occupy the execution time of the CPU inside the controller, and the more the number of sensors, the longer the time taken. It is a disadvantage for systems that require high real-time performance

Therefore, this method is not suitable for use in high-speed sheet media processing systems
