The coin outlet driving module drives and controls the coin outlet to release coins with corresponding coin values and quantity according to the coin outlet information transmitted by the MPU, such as the number of coins with the coin value to be output.

The power supply module provides required electric energy for the whole paper money machine, ensures normal operation of other modules, and manages distribution of electric energy so as to prevent overload or damage. For example, to power a motor drive module or the like. When the paper money machine is also connected with the coin outlet machine, the power supply module is also used for providing the required electric energy for the coin outlet machine. As shown in fig. 4, a circuit diagram of the connection of the power supply module 51, the motor driving module 52 and the coin outlet driving module 53 is shown.

In one embodiment, the power supply module includes an energy storage battery, such as a lithium battery, and a power management chip, where the power management chip transforms, converts, rectifies and stabilizes the electric energy in the energy storage battery and outputs the electric energy to each module in the circuit.

In one embodiment, as shown in fig. 5, the sensor module includes an input detection sensor, a banknote check sensor, and a banknote out detection sensor, wherein the input detection sensor is primarily responsible for monitoring the input mechanism of the banknote machine to determine whether a user has placed a banknote and to check whether the banknote is properly placed. When the user attempts to insert or deposit a banknote, the input detection sensor detects this action and then notifies the banknote input mechanism to begin accepting the banknote. If the banknote is not properly placed or if there is an abnormality, the input detection sensor may trigger an alarm or inform the banknote input mechanism to reject the banknote, ensuring proper operation of the banknote and avoiding erroneous operation. Fig. 6a is a schematic circuit diagram of the input detection sensor. The circuit implements banknote input detection using a plurality of phototransistors (Q1 to Q4), photodiodes (D1, D4) and a comparator (U1A, U B).

The main task of the banknote checking sensor is to verify the authenticity and denomination of the banknote. The banknote sensor will detect various characteristics of the incoming banknote, such as size, paper, watermark, texture, optical characteristics, etc., and compare it to known banknote information. If the banknote detection sensor determines that the banknote is authentic and recognizes its denomination, it will inform the banknote machine to continue the transaction process. If there is a problem, such as detecting counterfeit notes, the note verification sensor may trigger an operation to reject the note (e.g., withdraw the note) or an alarm.

The banknote outlet detection sensor is used for monitoring an output mechanism of the banknote machine so as to ensure successful banknote outlet or banknote returning operation. When a user needs to withdraw the paper money from the paper money machine, the paper money outlet detection sensor can detect the paper money outlet process of the output mechanism. If the banknote discharging operation is successful, the banknote discharging detection sensor informs the banknote discharging mechanism of releasing the banknote. If an abnormal condition occurs, such as a jammed banknote or a failure to properly eject a banknote, the banknote eject detection sensor may trigger a fault handling procedure, such as a beep, a voice, or an alarm. A schematic circuit diagram of the banknote detection sensor is shown in fig. 6 b.

The first LED time sequence control module is connected with the input detection sensor and used for controlling the color and/or the switching state of the first LED. The first LED time sequence control module is used for prompting the banknote input state according to the signal of the input detection sensor. For example, it may instruct the user to insert or insert a banknote by controlling the first LED to blink (switch) red continuously, by controlling the first LED to display green to indicate the user to insert or insert a banknote correctly, and by controlling the first LED to display yellow to indicate the user to insert or insert a banknote incorrectly.

The second LED time sequence control module is connected with the paper money detection sensor and used for controlling the color and/or the switching state of the second LED. The second LED time sequence control module is used for prompting the banknote checking state according to the signal of the banknote checking sensor. For example, it may indicate the authenticity and denomination of the banknote by controlling the color or flashing of the second LED. The second LED is controlled to continuously flash red to indicate that the paper money is counterfeit money, and the second LED lamp is controlled to display green to indicate that the paper money is genuine money.

The third LED time sequence control module is connected with the cash discharge detection sensor and used for controlling the color and/or the switching state of the third LED. The third LED time sequence control module is used for prompting the output state of the paper money according to the signal of the paper money output detection sensor. It can indicate whether the banknote is successfully ejected or ejected by controlling the color or flashing of the third LED. For example, a banknote abnormality such as a jam or no banknote is indicated by controlling the third LED to blink red continuously, and a successful banknote withdrawal is indicated by controlling the third LED to display lawyers.

Fig. 6c is a schematic circuit diagram of the first LED timing control module. The first LED comprises LED lamp beads with three colors of blue, green and red, and the on-off of the LED lamp beads with the three colors is controlled through signals INDI-B, INDI-G, INDI-R and switching tubes Q5, Q6 and Q7, so that different information is indicated. The first LED timing control module and the third LED timing control module are similar to the first LED timing control module. Through the cooperation of the LED time sequence control module and the MPU, a user can clearly know the working state of the paper money machine, so that visual feedback of user experience and operation is improved, and normal operation of the paper money machine is ensured.

The voice reminding module drives the external loudspeaker to send out voice reminding of 'normal banknote entering', and when banknote entering is abnormal, the voice reminding module drives the external loudspeaker to send out voice reminding of 'abnormal banknote entering', and the like.

In one embodiment, as shown in fig. 8, the circuit further includes a banknote box monitoring module, where the banknote box monitoring module is connected to the MPU processor module and is configured to detect the number of banknotes in a banknote box of the banknote machine, and send an alarm or notification when the number of banknotes in the banknote box reaches a preset maximum banknote amount, so as to prompt a user to maintain and empty the banknote box in time.
