This application can realize risk classification early warning through the analysis to waste product signal and good product signal to arouse staff's attention of different degree, the staff takes different measures according to the early warning difference. Specifically, the banknote paper flow direction online monitoring method comprises the following steps:
step 101, optical sensors are respectively arranged at a waste paper bin dividing port and a good paper bin dividing port of a cutting and sorting machine, a waste product signal is generated when the optical sensor arranged at the waste paper bin dividing port detects a waste product, and a good product signal is generated when the optical sensor arranged at the good paper bin dividing port detects a good product.

The waste products refer to banknote paper which does not accord with the regulation, and the good products refer to banknote paper which accords with the regulation.
And step 102, judging whether continuous waste discharge occurs or not according to the waste signal, and starting a first alarm to give an alarm if the continuous waste discharge occurs.
When the method is implemented, the process of judging whether continuous waste discharge occurs according to the waste signal comprises the following steps: counting the number of the waste signals in a first time period after the generation of the waste signals, and if the number of the waste signals in the first time period is greater than a first preset risk threshold, if the first preset risk threshold is 4, and 5 waste signals are monitored within 1 second, determining that continuous waste discharge occurs.
And 103, judging whether continuous waste discharge is finished or not and whether waste discharge is missed or not according to good product signals generated in the alarm period of the first alarm, finishing the alarm of the first alarm if the continuous waste discharge is finished, and starting the second alarm if the waste discharge is missed.

counting the number of good signals in a second time period from the time when the first alarm generates the good signals in the alarm period, if the number of the good signals in the second time period is less than or equal to a second preset risk threshold, if the second preset risk threshold is 4, monitoring 1, 2, 3 or 4 good signals in 1 second, determining that the waste discharge is missed (the waste is shunted to the good), and otherwise, determining that the continuous waste discharge is finished.
In this embodiment, in order to distinguish the alarm level, the first alarm is a yellow sound and light integrated alarm, and the second alarm is a red sound and light integrated alarm.
In an embodiment of the application, the first preset risk threshold is determined according to the limit number of pages of paper passing through the cutting machine in a first time period; the second preset risk threshold is determined according to the limit number of paper sheets passing through the paper selector in the second time period.
In some embodiments, the first time period is 1s, the second time period is 2s, and the second preset risk threshold is 2 times the first preset risk threshold. In other embodiments, the first time period and the second time period are both 1s, and the first preset risk threshold is the same as the second preset risk threshold.

The third alarm is an audible and visual alarm with a color different from the first alarm and the second alarm, such as a blue audible and visual alarm.
In an embodiment of the present application, the distribution rules of the waste signals and the good signals of the continuous waste discharge under various reasons can be analyzed in advance, and the generation reason of the continuous waste discharge to be analyzed can be determined according to the rules analyzed in advance.
The continuous waste discharge is mainly caused by the following reasons: 1) because the currency paper needs to be embedded with the anti-counterfeiting safety line, the process of replacing the safety line roller each time can lead to batch 'wireless paper', and the paper is regarded as 'continuity risk product' in the subsequent quality inspection process; 2) the paper making equipment is large and complex, and batch 'continuity risk products' can be generated when each mechanism breaks down; 3) in the paper making process, paper advances forwards along a large number of guide rollers, felts, traction rollers and calender rollers, and once sundries are attached, batch 'continuity risk products' can be generated; 4) operator-generated malfunctions can also generate batches of "continuity risk products". The product quality risks cannot be completely eradicated, and the continuous risk products are eliminated in a subsequent quality inspection link.

the second optical sensor 202 is arranged at a good paper bin opening of the cutting and sorting machine and used for detecting good products, and when a good product is detected, a good product signal is generated and sent to the processor 303;
the processor 203 judges whether continuous waste discharge occurs or not according to the waste signals, and if the continuous waste discharge occurs, the first alarm 204 is started to alarm; and judging whether continuous waste discharge is finished or not and whether waste discharge leakage occurs or not according to a good product signal generated in the alarm period of the first alarm, finishing the alarm of the first alarm 204 if the continuous waste discharge is finished, and starting the second alarm 205 to alarm if the waste discharge leakage occurs.
In some embodiments, the first optical sensor 201 and the second optical sensor 202 are DATALOGIC-PP-200 sensors, and two optical sensors are respectively arranged at the waste paper bin dividing port and the good paper bin dividing port.
In some embodiments, the first alarm 204 is a yellow sound and light integrated alarm, the second alarm 205 is a red sound and light integrated alarm, and the first alarm and the second alarm are disposed at the corresponding bin splitting openings through the fixing brackets.
In some embodiments, the first time period and the second time period are a unit time, such as 1 s. The first preset risk threshold and the second preset risk threshold are determined according to the limit number of paper sheets passing through the paper cutting machine in unit time.
In some embodiments, the process of determining whether continuous waste discharge occurs by the processor 203 according to the waste signal includes: counting the number of the waste signals in a first time period after the generation of the waste signals, and determining continuous waste discharge if the number of the waste signals in the first time period is greater than a first preset risk threshold.
In some embodiments, the process of determining whether the continuous waste discharge is finished and whether the waste discharge is missed by the processor 203 according to the good signal generated during the alarm period of the first alarm comprises the following steps:
and counting the number of good signals in a second time period from the time when the good signals appear in the alarm period of the first alarm, if the number of the good signals in the second time period is less than or equal to a second preset risk threshold value, determining that the waste discharge is missed, and otherwise, determining that the continuous waste discharge is finished.

Whether continuous waste discharge occurs or not can be judged by monitoring and analyzing the waste product signals and the good product signals, and whether waste discharge leakage occurs or not (the risk products enter the good paper channel) exists or not during the continuous waste discharge. If continuous waste discharge occurs, a first alarm is started to alarm on a first layer, and if the first alarm alarms in a period of missing waste discharge, a second layer is started to alarm. According to the method and the device, risk grading early warning can be realized, so that corresponding measures can be taken by workers according to different early warnings, and serious quality risks caused by 'continuous waste discharge' and 'waste leakage discharge' are avoided.
