[0043] The main control module 11 is connected to the two-dimensional code scanning module 12 through a first USB interface, is communicatively connected to the RFID card reader module 13 through a serial port, and is communicatively connected to the door lock control module 14 through a first RS485 interface.
[0044] The door lock control module 14 is connected to the return door electronic lock 15 through the first solenoid valve interface and is connected to the return door micro switch 16 through the first feedback signal interface. The return door electronic lock 15 is equipped with a return lock micro switch. When the door lock control module 14 supplies power to the return door electronic lock 15, the lock tongue retracts and the return door can be pushed open. At the same time, the retraction of the lock tongue triggers the return lock micro switch, and the door lock control module 14 determines the door lock state of the return door electronic lock 15 by acquiring the state of the return lock micro switch.
[0045] The two-dimensional code scanning module 12 is used to scan the two-dimensional code of the product.
[0046] The RFID card reading module 13 is used to read the electronic tag of the commodity.
[0047] The door lock control module 14 is used to open or close the electronic lock of the return door.
[0048] The main control module 11 is used to receive the QR code, and when the QR code is a valid code, send a first unlocking instruction to the door lock control module 14 to open the return door electronic lock 15; and receive a first micro-motion signal output by the return door micro-switch 16, and control the RFID card reader module 13 to read the electronic tag of the product according to the first micro-motion signal; and when the electronic tag is a valid tag, send a first locking instruction to the door lock control module 14 to close the return door electronic lock 15.
[0049] In this embodiment, the QR code of the goods sold by the self-service goods rental, sale and return device is scanned by the QR code scanning module to confirm whether the goods are valid goods. When the goods are confirmed to be valid goods, the main control module controls the electronic lock of the return door of the self-service goods rental, sale and return device to open. If the goods are correctly returned to the self-service goods rental, sale and return device through the return door, at this time, the return door microswitch generates a first micro signal, the main control module receives the first micro signal, turns on the RFID card reading module to read the electronic tag of the goods, and further confirms the validity of the goods. When it is confirmed that the electronic tag of the goods is a valid tag, the main control module controls the door lock control module to close the electronic lock of the return door to ensure the validity of the returned goods, thereby realizing the effective return of the rental and sale goods.
[0050] In another embodiment, Figure 2As shown, a self-service commodity rental and sale return device is provided. In addition to the following Figure 1 In addition to the modules shown, it also includes a cargo lane control module 17, a grating beam detector 18, a cargo lane motor module 19, a pickup door electronic lock 20, and a pickup door micro switch 21.
[0051] The cargo lane control module 17 is connected to the main control module 11 through the second RS485 interface. The grating detector 18 is connected to the cargo lane control module 17 through the grating detection interface, and the cargo lane motor module 19 is connected to the cargo lane control module 17 through various motor interfaces.
[0052] The door lock control module 14 is connected to the pickup door electronic lock 20 through the second solenoid valve interface and is connected to the pickup door micro switch 21 through the second feedback signal interface. The pickup door electronic lock 20 is equipped with a pickup lock micro switch. When the door lock control module 14 supplies power to the pickup door electronic lock 20, the lock tongue retracts and the pickup door can be pushed open. At the same time, the retraction of the lock tongue triggers the pickup lock micro switch, and the door lock control module 14 determines the door lock state of the pickup door electronic lock 15 by obtaining the state of the pickup lock micro switch.
[0053] The cargo lane control module 17 is used to receive the shipping instructions sent by the main control module and control the motor in the cargo lane motor module 19 to rotate and drop the goods.
[0054] The cargo lane motor module 19 is used to store the commodities. The cargo lane motor module 19 is composed of various motors, tracks, cargo push plates and cargo lane micro switches, wherein the cargo push plates are fixed on the tracks.
[0055] When the cargo lane control module 17 supplies power to the corresponding motor interface, the motor will start to rotate, and the motor will drive the track to rotate. Since the cargo push plate is fixed on the track, the push plate will push the goods forward until the goods fall out of the track. The cargo push plate has an initial position. After the motor drives the track and the push plate to rotate a circle, the push plate will trigger the cargo lane micro switch. The cargo lane motor module 19 will send the state of the cargo lane micro switch, i.e., the motor feedback signal, to the cargo lane control module 17. The cargo lane control module 17 sends the motor feedback signal to the main control module 11, receives the stop-sale instruction returned by the main control module, controls the motor interface to cut off power, and stops the motor from rotating.
[0056] The grating detector 18 is used to output the grating signal changed when the commodity falls. The grating detector 18 includes a transmitting unit and a receiving unit, wherein the receiving unit is connected to the grating detection interface of the cargo lane control module 17, and the receiving unit supplies power to the transmitting unit through a set of wiring harnesses.
[0057] The main control module 11 is also used to send a shipping instruction to the aisle control module 17 to control the motor in the aisle motor module 19 to rotate and drop the goods; and receive the grating signal, and when the grating signal is a valid signal, send a stop-sale instruction to the aisle control module 17 to control the motor to stop rotating; and send a second unlocking instruction to the door lock control module 14 to open the pickup door electronic lock 20; and receive the second micro-motion signal output by the pickup door micro-switch 21, and send a second locking instruction to the door lock control module 14 to close the pickup door electronic lock 20.
[0058] Specifically, in this embodiment, the self-service goods rental and sale are realized through the cargo aisle control module 17, the cargo aisle motor module 19, the pickup door electronic lock 20 and the pickup door micro switch 21. At the same time, the cargo aisle micro switch in the cargo aisle motor module 19 is used to detect the number of rotations of the motor of the cargo aisle motor module. The default setting is that the motor stops rotating after one rotation, which solves the problem of over-shipping of vending machines in the prior art. In addition, a grating beam detector 18 is set. During the falling process of the goods, the grating beam detector 18 will pass through the grating beam detector 18. According to the grating signal output by the grating beam detector 18, it is confirmed whether there is any goods falling. If the grating signal shows that the goods have not fallen, the main control module 11 will continue to send the delivery instruction to the cargo aisle control module 17. If the grating signal shows that the goods have fallen successfully, the main control module 11 sends a second unlocking instruction to the door lock control module 14 to open the pickup door electronic lock 20, which solves the problem of unsuccessful delivery of vending machines in the prior art. After the goods are taken away through the pickup door, the pickup door micro switch 21 outputs a second micro signal to the main control module 11, and the main control module 11 sends a second lock command to the door lock control module 14 to close the pickup door electronic lock 20.
[0059] Furthermore, after the main control module 11 determines that the product has fallen based on the grating signal, it will again send a stop-sale instruction to the aisle control module 17 to control the corresponding motor to stop rotating, thereby avoiding the failure of the aisle microswitch in the aisle motor module 19 and causing continued shipment, thereby realizing a double detection mechanism to ensure that the device will not have the problem of over-shipping.
[0060] Furthermore, the autonomous commodity rental, sale and return device further includes: a display module 22 connected to the main control module 11 via a display interface. In order to prevent the electronic lock 20 of the pickup door or the electronic lock 15 of the return door from being damaged due to excessive temperature caused by long-term power-on, the electronic lock 20 of the pickup door or the electronic lock 15 of the return door will automatically shut down after the power-on time exceeds the set time. The display module 22 is used to display the closing countdown of the electronic lock 20 of the pickup door or the electronic lock 15 of the return door.
[0061] More preferably, the self-service merchandise rental, sale and return device further comprises: a speaker module 23 connected to the main control module 11 via a speaker interface.

[0090] Among them, Figure 7 As shown, a circuit diagram is provided when the door lock control module 14 is in communication connection with the return door electronic lock 15 or the pickup door electronic lock 20 or the replenishment door electronic lock 29 or the recycling door electronic lock 30, including a door control MCU chip, a resistor R50, a resistor R51, a resistor R52, a MOS tube Q1, a connector J3, a capacitor C19, a capacitor C20, a diode D3, a connector J21, and a capacitor C26.
[0091] The CTL pin of the gate control MCU chip is connected to the resistor R51, and the other end of the resistor R51 is respectively connected to the resistor R52 and the gate pin 4 of the MOS tube Q1; the source pin 1, pin 2, and pin 3 of the MOS tube Q1 are all connected to the system ground, the drain pin 5, pin 6, pin 7, and pin 8 of the MOS tube Q1 are connected to pin 2 of the connector J3, and the 12V power supply is connected to pin 1 of the connector J3; one end of the capacitor C19 is connected to the 12V power supply, and the other end of the capacitor C19 is connected to the system ground; one end of the capacitor C20 is connected to the 12V power supply, and the other end of the capacitor C20 is connected to the system ground; one end of the diode D3 is connected to the 12V power supply, and the other end of the diode D3 is connected to pin 2 of the connector J3, pin 1 of the connector J3 is connected to the positive electrode of the door electronic lock 15, and pin 2 of the connector J3 is connected to the negative electrode of the door electronic lock 15. The DET pin of the door control MCU chip is connected to resistor R50, and the other end of R50 is connected to pin 1 of J21. At the same time, the other end of R50 is connected to capacitor C26 to the system ground. Pin 2 of connector J21 is connected to the system ground, and pin 1 of J21 is connected to the door lock status signal fed back from the lock micro switch.
[0092] The specific manner in which the door lock control module 14 controls the return door electronic lock 15 or the pickup door electronic lock 20 or the replenishment door electronic lock 29 or the recycling door electronic lock 30 is as follows:
[0093] When the door lock control module 14 controls the corresponding door to open, the CTL pin of the door control MCU chip generates a high-level signal. After the voltage is divided by resistors R51 and R52, the gate voltage of the MOS tube Q1 is still high, and the source voltage of the MOS tube Q1 is 0. Therefore, the VGS voltage of the MOS tube Q1 is greater than the MOS conduction threshold voltage, and the MOS tube is turned on, that is, the drain and source of the MOS tube Q1 are turned on. Since the drain of the MOS tube Q1 is connected to pin 2 of the connector J3, and pin 2 of the connector J3 is connected to the negative pole of the door electronic lock, the negative pole of the door electronic lock is connected to the system ground. Since the positive pole of the door electronic lock is connected to the 12V power supply, the door electronic lock will retract the lock tongue after the power supply is turned on, and the door can be opened.
[0094] When the door lock control module 14 controls the corresponding door to close, the CTL pin of the door control MCU chip generates a low-level signal. After the voltage is divided by resistors R51 and R52, the gate voltage of the MOS tube Q1 is also low, and the source voltage of the MOS tube Q1 is 0. Therefore, the VGS voltage of the MOS tube Q1 is 0, which is less than the conduction threshold voltage of the MOS, and the MOS tube Q1 is not turned on. At this time, the negative pole of the door electronic lock is not connected to the system ground. Even if the positive pole of the door electronic lock has a 12V power supply, a loop cannot be formed. The door electronic lock has no power supply and the lock tongue is ejected. At this time, the door cannot be opened and the door is in a closed state. Since the door electronic lock is a magnetic device, a reverse electromotive force will be generated after the door electronic lock is powered off. The freewheeling diode D3 can protect the MOS tube Q1 from being damaged by the reverse electromotive force. The state of the lock micro switch on the door electronic lock is given to the DET pin of the MCU chip of the door lock control module 14 through the 1st pin of the connector J21, and the door lock control module 14 obtains the door lock state of the door electronic lock.
[0095] Among them, Figure 8 As shown, a circuit diagram of the channel control module 17 and the channel motor module 19 is provided when communicating and connecting, including: a channel MCU chip, a motor driver chip U5, a connector J2 of the channel motor module 19, a capacitor C23, a capacitor C24, a capacitor C25, a capacitor C27, a resistor R68, a capacitor C72,
[0096] The MTR_CTL_1_A pin of the aisle MCU chip of the aisle control module 17 is connected to pin 2 of the motor driver chip U5, and the MTR_CTL_1_B pin of the aisle MCU chip is connected to pin 3 of the motor driver chip U5; pin 1 of the motor driver chip U5 is connected to a 3.3V power supply, one end of capacitor C23 is connected to pin 1 of the motor driver chip U5, and the other end is connected to the system ground; pin 5 of the motor driver chip U5 is connected to a 3.3V power supply, one end of capacitor C24 is connected to pin 5 of the motor driver chip U5, and the other end is connected to the system ground; pin 4 of the motor driver chip U5 is connected to a 12V power supply, one end of capacitor C25 is connected to pin 4 of the motor driver chip U5, and the other end is connected to the system ground; pin 8 of the motor driver chip U5 is connected to a 12V power supply, and one end of capacitor C27 is connected to the motor Pin 8 of the driver chip U5 is connected to the system ground at the other end; pins 10, 11, 14 and 15 of the motor driver chip U5 are connected to the system ground, pin 16 of the motor driver chip U5 is connected to pin 4 of the connector J2, and pin 4 of the connector J2 is also connected to the positive pole of the aisle motor, pin 13 of the motor driver chip U5 is connected to pin 3 of the connector J2, and pin 3 of the connector J2 is also connected to the negative pole of the aisle motor, pin 2 of the connector J2 is connected to the MOTOR_DET_1 pin of the aisle MCU chip through resistor R68, and pin 2 of the connector J2 is also connected to the motor feedback signal of the aisle motor; one end of the capacitor C72 is connected to the MOTOR_DET_1 pin of the aisle MCU chip, and the other end is connected to the system ground; pin 1 of the connector J2 is connected to the system ground.
[0097] The specific method in which the cargo lane control module 17 controls the motor of the cargo lane motor module 19 to rotate and drop the goods is as follows:
[0098] When the cargo lane control module 17 receives the delivery instruction, the cargo lane MCU chip MTR_CTL_1_A pin generates a high-level signal, and the MTR_CTL_1_B pin generates a low-level signal. According to the levels of these two sets of control signals, the motor driver chip U5 will output a 12V voltage to the positive pole of the corresponding motor at the 16th pin of the motor driver chip U5, and the motor driver chip U5 will output a 0V voltage to the negative pole of the corresponding motor at the 13th pin. The cargo lane motor will generate positive rotation after there is a positive power supply at both ends. When the motor rotates, the goods will be transmitted to the cargo port through the transmission structure. After the motor rotates one circle, it will trigger the cargo lane micro switch on the cargo lane motor module, and the cargo lane micro switch outputs the motor feedback signal. The MOTOR_DET_1 pin of the cargo lane MCU chip detects that the motor rotates one circle through the motor feedback signal, and then controls the motor driver chip U5 to stop rotating the motor.
[0099] like Figure 8As shown, the circuit also includes a connector J4, a resistor R164, and a capacitor C78 of the grating beam detector 18. One end of the resistor R164 is connected to pin 2 of the connector J4, and the other end is connected to the SHOP_DET pin of the channel MCU chip to output the grating signal; one end of the capacitor C78 is connected to the SHOP_DET pin of the channel MCU chip, and the other end is connected to the system ground; the 4th pin of the connector J4 is connected to the 12V power supply, and the 1st pin of the connector J4 is connected to the system ground.
[0100] As the second level of detection of whether the shipment is successful, when the aisle MCU chip of the aisle control module 17 detects that the shipment is successful through the SHOP_DET pin, even if the aisle microswitch on the aisle motor module 19 fails, it will control the motor driver chip U5 to stop rotating the motor to avoid over-shipping.
[0101] In this example embodiment, the detection mechanism of self-service vending is improved through the cargo lane control module 17, the grating beam detector 18 and the cargo lane motor module 19, which solves the problem of over-delivery and unsuccessful delivery of vending machines in the prior art.
