In addition, the terms “first” and “second” are used to distinguish different objects, not to describe a specific order.

[0048] The implementation of the present disclosure will be described in detail below in combination with specific drawings:

[0049] Figure 1 is a structural schematic diagram of a travel scenic spot unmanned vending system provided by an embodiment of the present disclosure. Referring to Figure 1 , the travel scenic spot unmanned vending system comprises:

[0050] a personnel detection module 101, a light adjusting controller 102, a light adjusting module 103, a power supply module 104, a touch display screen 105, a weight detection module 106, a central control module 107, a code scanning module 108, a delivery controller 109 and a delivery module 110;

[0051] The light adjusting controller 102 is connected with the personnel detection module 101, the light adjusting module 103 and the central control module 107 respectively;

[0052] The light adjusting module 103 is connected with the power supply module 104 and the touch display screen 105 respectively;

[0053] The code scanning module 108 is connected with the touch display screen 105, the delivery controller 109 and the central control module 107 respectively;

[0054] The weight detection module 106 is connected with the central control module 107;

[0055] The delivery controller 109 is connected with the delivery module 110 and the central control module 107 respectively;

[0056] The personnel detection module 101 is configured to detect whether there is a person in a certain area in front of the unattended vending system;

[0057] The light adjusting module 103 is configured to adjust the brightness of the touch display screen 105.

[0058] In the embodiment, the personnel detection module 101 is configured to detect whether a person is active in front of the unattended vending system. The personnel detection module 101 can be an infrared sensor or a camera, which is used to detect a certain area in front of the unattended vending machine in real time. The area and the position can be set according to the sensitivity of the infrared sensor. When a person is detected in the detection range, an electrical signal is output.

[0059] The light adjusting controller 102 receives the electrical signal of the personnel detection module 101, and controls the light adjusting module 103 to adjust the brightness of the touch display screen 105 according to whether there is a person and other setting conditions. When the personnel detection module 101 detects that a person approaches, the light adjusting controller 102 receives the signal, sends an instruction to the light adjusting module 103, adjusts the brightness of the touch display screen 105 according to the current environmental light and other factors, and transmits the information that a person approaches to the central control module 107, so that the central control module 107 performs other operations, such as starting the code scanning module 108.

[0060] The light adjusting module 103 adjusts the brightness of the touch display screen 105 according to the instruction of the light adjusting controller 102, so as to adapt to different environmental light, and is connected with the power supply module 104 to obtain electrical energy.

[0061] The touch display screen 105 is a human-computer interaction interface, which is used to display commodity information, operation prompt and the like, and receives touch operation instructions of the user. The user can browse commodity types, price and other information through the touch display screen 105, select commodities and perform payment and other operations.

[0062] The weight detection module 106 includes a plurality of weight sensors, which are arranged at different weight detection positions of the commodity shelf and are configured to detect whether the goods on the commodity shelf have been delivered, or judge whether the delivery is normal according to the weight change.

[0063] The central control module 107 is used to coordinate the work between various modules, receive signals from various modules, and then send control instructions to the corresponding modules. For example, when receiving the payment success signal of the code scanning module 108, send the delivery instruction to the delivery controller 109.

[0064] The code scanning module 108 displays the payment QR code, which is used to realize the payment function. The user can pay the amount by scanning the QR code, and send the payment information to the central control module 107.

[0065] The delivery controller 109 controls the delivery module 110 to deliver the goods purchased by the user according to the delivery instruction of the central control module 107, and feeds back the delivery status to the central control module 107. When the central control module 107 receives the payment success signal of the code scanning module 108, it sends a delivery instruction to the delivery controller 109. The delivery controller 109 controls the motor or electromagnet and other equipment to drive the delivery module 110 to push the goods out to the delivery port.

[0066] The delivery module 110 delivers the goods purchased by the user according to the delivery instruction of the delivery controller 109, completes the transaction link, and can be composed of a push rod type delivery structure. Under the control of the delivery controller 109, the goods are moved from the storage position to the delivery port, which is convenient for the user to take the goods.

[0067] For example, an unattended vending machine is set at the entrance of a certain tourist attraction. When the tourist approaches the unattended vending machine, the personnel detection module 101 (infrared sensor) detects a person and sends a signal to the dimming controller 102. The dimming controller 102 sends a dimming instruction to the dimming module 103 to control the dimming module 103 to adjust the brightness of the touch display screen 105 to the brightness suitable for the current environment. The tourist browses the product information on the touch display screen 105, selects the desired product, and uses the mobile phone to scan the code and pay through the code scanning module 108. After the code scanning module 108 recognizes the payment information, it sends the payment information to the central control module 107. After the central control module 107 confirms the payment success, it sends a delivery instruction to the delivery controller 109. The delivery controller 109 controls the delivery module 110 (push rod type structure) to push the goods out to the delivery port. At the same time, the weight detection module 106 detects the weight change of the goods shelf in real time.

[0068] From the above, the present disclosure automatically perceives the arrival of customers through the personnel detection module 101, and the dimming module 103 adjusts the brightness of the touch display screen 105 accordingly, which not only improves the user experience but also realizes energy saving and consumption reduction. As an interactive interface, the touch display screen 105 provides intuitive product information and operation guidance, simplifies the purchase process, and enhances the self-service shopping experience of tourists. Secondly, the introduction of the code scanning module 108 makes the payment method more diversified and convenient, supports quick code scanning payment, and meets the needs of modern consumers for efficient and secure payment. At the same time, the weight detection module 106 ensures the accuracy of the transaction, effectively prevents the situation of mis-selling or loss of goods, and ensures the reliability of the system. Finally, the central control module 107 realizes intelligent management and coordination of each module, ensuring the smoothness and efficiency of the entire sales process. Therefore, the present disclosure can improve the reliability of screen brightness adjustment.

[0069] In an embodiment of the present disclosure, with reference to Figure 2 , the dimming module 103 includes a photodiode U2, a dimming switch U1, a light-emitting diode LED1, a resistor R1, a resistor R2, a resistor R3, and a capacitor C1;

[0070] The first end of the dimming switch U1 is connected to the cathode of the light-emitting diode LED1, and the anode of the light-emitting diode LED1 is connected to the fourth end of the dimming switch U1 and the first end of the resistor R1, respectively;

[0071] The second end of the dimming switch U1 is grounded; the third end of the dimming switch U1 is connected to the cathode of the photodiode U2, and the anode of the photodiode U2 is grounded, and the third end of the dimming switch U1 is connected to the VCC power supply through the resistor R2;

[0072] The fifth end of the dimming switch U1 is connected to the second end of the resistor R1, and the fifth end of the dimming switch U1 is connected to the first end of the resistor R3, and the second end of the resistor R3 is connected to the power supply of the dimming module 103;

[0073] The capacitor C1 is connected in parallel with the resistor R3.

[0074] In this embodiment, the dimming module 103 is used to adjust the brightness of the light-emitting diode LED1, the light intensity is sensed by the photodiode U2, and the current of the light-emitting diode LED1 is controlled by the dimming switch U1 to realize brightness adjustment. The dimming switch U1 can be a chip PT4115.

[0075] When the intensity of the ambient light changes, the reverse current of the photodiode U2 changes accordingly, and the changed current is converted into a voltage signal by the resistor R2 and transmitted to the third terminal of the dimmer switch U1. The dimmer switch U1 adjusts the current output to the light-emitting diode LED1 according to the voltage signal, thereby changing the brightness of the light-emitting diode LED1. The resistor R1 limits the current of the light-emitting diode LED1 to prevent damage to the light-emitting diode LED1 due to excessive current. The capacitor C1 and the resistor R3 form a filter circuit in parallel.

[0076] For example, when the ambient light is strong, the reverse current of the photodiode U2 increases, and the dimmer switch U1 reduces the output current, causing the brightness of the light-emitting diode LED1 to decrease. When the ambient light is weak, the reverse current of the photodiode U2 decreases, and the dimmer switch U1 increases the output current, causing the brightness of the light-emitting diode LED1 to increase.

[0077] As can be seen from the above, the dimming module 103 uses the photodiode U2 in combination with the dimmer switch U1 to achieve intelligent adjustment of the brightness of the light-emitting diode LED1. In this embodiment, the photodiode U2 senses the intensity of the ambient light, and the dimmer switch U1 dynamically adjusts the brightness of the light-emitting diode LED1 according to the sensing result, thereby ensuring clear visibility of the touch display screen 105 in different light environments and effectively saving electrical energy.

[0078] In one embodiment of the present disclosure, with reference to Figure 2 , the power supply module 104 includes a photovoltaic panel, a voltage stabilizing tube D1, a battery, a power detection circuit, a first comparator U4, a second comparator U5, an OR gate U6, a switch K1, a voltage detection circuit, a third comparator U3, an AND gate U7, a triode Q3, a relay K2, and a voltage regulation circuit;

[0079] The cathode of the voltage stabilizing tube D1 is connected to the photovoltaic panel, and the anode of the voltage stabilizing tube is connected to the resistor R3.

[0080] The power detection circuit is connected to the inverting input terminal of the first comparator U4 and the inverting input terminal of the second comparator U5, respectively.

[0081] The non-inverting input terminal of the first comparator U4 receives a reference power Vref1, and the non-inverting input terminal of the second comparator U5 receives a reference power Vref2.

[0082] The output terminal of the first comparator U4 is connected to the first input terminal of the OR gate U6, and the output terminal of the second comparator U5 is connected to the second input terminal of the OR gate U6.

[0083] The output terminal of the OR gate U6 is connected to the control terminal of the switch K1.

[0084] The first terminal of the switch K1 is connected to the battery, and the second terminal of the switch K1 is connected to the anode of the voltage stabilizing tube D1.

[0085] The input end of the voltage detection circuit is connected with the photovoltaic panel;

[0086] The output end of the voltage detection circuit is connected with the inverting input end of the third comparator U3, the non-inverting input end of the third comparator U3 receives the reference voltage Vref3, and the output end of the third comparator U3 is connected with the first input end of the AND gate U7;

[0087] The second input end of the AND gate U7 is connected with the output end of the OR gate U6, and the output end of the AND gate U7 is connected with the base of the transistor Q3;

[0088] The collector of the transistor Q3 is connected with the VCC power supply, and the emitter of the transistor Q3 is connected with the first input end of the relay K2, and the second input end of the relay K2 is grounded;

[0089] The first normally open end of the relay K2 is connected with the voltage regulation circuit, and the common end of the relay K2 is connected with the second end of the resistor R3.

[0090] In the embodiment, the photovoltaic panel is used to convert solar energy into electrical energy. When the output voltage of the photovoltaic panel is less than the voltage of the stabilizing tube D1, the stabilizing tube D1 is cut off; when the output voltage of the photovoltaic panel is greater than the voltage of the stabilizing tube D1, the stabilizing tube D1 is broken down and turned on, at this time, the photovoltaic panel can supply power to the dimming module 103.

[0091] The power detection circuit is configured to detect the power of the storage battery in real time. The first comparator U4 compares the detected power of the storage battery with the reference power Vref1, when the power of the storage battery is greater than the reference power Vref1, the first comparator U4 outputs a signal "0", that is, a low level; when the power of the storage battery is less than the reference power Vref1, the first comparator U4 outputs a signal "1", that is, a high level, and the reference power Vref1 can be 100% of the power.

[0092] The second comparator U5 compares the detected power of the storage battery with the reference power Vref2, when the power of the storage battery is greater than the reference power Vref2, the second comparator U5 outputs a signal "0", that is, a low level; when the power of the storage battery is less than the reference power Vref2, the second comparator U5 outputs a signal "1", that is, a high level, and the reference power Vref1 can be 20% of the power.

[0093] The logic of the OR gate U6 is that as long as one input is high, the output is high. The output signals of the first comparator U4 and the second comparator U5 are combined to control the closing and opening of the switch K1. When the OR gate U6 outputs a high level, the switch K1 is closed, and the photovoltaic panel can charge the storage battery; when the output is low, the switch K1 is opened, and the charging is stopped.

[0094] The voltage detection circuit is used for detecting the output voltage of the photovoltaic panel. The third comparator U3 compares the output voltage of the photovoltaic panel with the reference voltage Vref3 and outputs a corresponding level signal. When the output voltage of the photovoltaic panel is less than the reference voltage Vref3, the third comparator U3 outputs a high level; when the output voltage of the photovoltaic panel is greater than the reference voltage Vref3, the third comparator U3 outputs a low level.

[0095] The logic of the AND gate U7 is that the output is high only when both inputs are high. The AND gate U7 integrates the information of the photovoltaic panel voltage and the battery power, and is used for controlling the transistor Q3. When the AND gate U7 outputs a high level, the transistor Q3 is turned on to provide current for the relay K2. When the transistor Q3 is turned on, the relay K2 is energized to attract and connect to the voltage regulation circuit for supplying power to the dimming module 103; otherwise, the relay K2 is disconnected to stop supplying power to the dimming module 103. The voltage regulation circuit receives the mains and adjusts it to a suitable voltage value to provide stable power for the load.

[0096] From the above, it can be seen that the power supply module 104 realizes intelligent management of the power energy of the unmanned vending system. The embodiment not only improves the energy utilization efficiency, but also enhances the power supply reliability of the system, thereby providing a strong guarantee for the continuous operation of the unmanned vending system.

[0097] In an embodiment of the present disclosure, referring to Figure 3 An unmanned vending system for a cultural and travel scenic area further includes an electronic tag 111;

[0098] The electronic tag 111 is arranged at a plurality of positions of the commodity shelf;

[0101] The pressure detection module 112 is used for being connected with the load-bearing platform;

[0102] The pressure detection module 112 is connected to the central control module 107.

[0103] In an embodiment of the present disclosure, referring to Figure 3 An unmanned vending system for a cultural and travel scenic area further includes a communication module 113 and a remote monitoring center 114;

[0104] The communication module 113 is connected with the central control module 107 and the remote monitoring center 114, respectively.

[0105] In an embodiment of the present disclosure, referring to Figure 3A travel scenic spot unmanned vending system also includes an alarm module 115.

[0106] The alarm module 115 is connected to the central control module 107.

[0107] In this embodiment, the electronic tags 111 are placed at multiple locations on the product shelves and can store detailed information about the products, such as product names, prices, specifications, etc. Users can learn about product details through the electronic tags 111. At the same time, the central control module 107 can control the information modification of the electronic tags 111.

[0108] The load platform is where the products are placed, and the pressure detection module 112 can detect changes in pressure on the load platform. When a product is taken away, the pressure on the load platform will change, and the pressure detection module 112 will convert the pressure change into an electrical signal and send it to the central control module 107.

[0109] The communication module 113 can transmit data between the central control module 107 and the remote monitoring center 114. The central control module 107 will send various operating data of the unmanned vending system (such as sales data, inventory information, equipment status, etc.) to the remote monitoring center 114 through the communication module 113. The management personnel of the remote monitoring center 114 can real-time grasp the operation of each unmanned vending machine, and make decisions such as timely restocking and equipment maintenance. At the same time, the remote monitoring center 114 can also send control instructions to the central control module 107 through the communication module 113, such as adjusting product prices, updating promotional activity information, etc.

[0110] The alarm module 115 is used to issue an alarm when the unmanned vending system encounters an abnormal situation. When the central control module 107 detects an anomaly, such as product misuse (judged by the pressure detection module 112 or other sensors), it will send a signal to the alarm module 115. The alarm module 115 can issue an alarm through sound (such as a beeping sound), flashing lights, etc. to remind the management personnel to handle the problem in a timely manner and ensure the normal operation of the unmanned vending system.

[0111] From the above, it can be concluded that the electronic tags 111 achieve reading of product information. The combination of the pressure detection module 112 and the load platform enables real-time detection of whether a product has been taken away. The connection of the communication module 113 and the remote monitoring center 114 enables management personnel to remotely monitor the vending system status, achieving intelligent management. In addition, the setting of the alarm module 115 enables timely alarm in abnormal situations, ensuring system safety.
