Description

Technical Field

[0001] This invention relates to the field of smart shopping carts, and more specifically, to a method, system, and apparatus for identifying smart shopping carts. Background Technology

[0002] With the development of the information age, more and more industries are undergoing intelligent upgrades. Traditional shopping carts in supermarkets are becoming increasingly difficult to adapt to the needs of smart supermarkets, and new types of intelligent shopping carts are emerging in greater numbers.

[0003] Currently, most smart shopping carts use a continuous interleaved contact (plug-in) charging method. However, when using contact charging, it is impossible to determine which charging station the shopping cart is charging at or which number of carts it is on. If an abnormality occurs while a shopping cart is charging, it is impossible to know which charging station and which shopping cart it is on, and therefore, corresponding safety measures cannot be taken. This can easily lead to accidents.

[0004] Chinese patent application No. 201910885974.5, published on February 7, 2020, discloses a smart shopping cart, including a shopping cart and a controller. The controller, installed on the shopping cart, is used to locate the cart's position in real time, display product information to customers in real time, optimize the path for desired products, provide related information about the products, and provide a search interface for customers to quickly search for the location of the products. This invention, through the setting of the positioning system, requires the shopping cart to reach a specific location before disconnecting from the mobile phone during use and return. This setting helps shopping malls strengthen the management of shopping carts and promotes their neat and orderly placement. Furthermore, the positioning device can pinpoint the location of the shopping cart and establish an optimal path between the cart and the selected products, thus facilitating consumers to quickly locate the products they need, saving time and reducing unnecessary time wasted during shopping. However, due to the inaccuracy of the positioning system, it is difficult to accurately identify shopping carts with charging issues when there are many carts present. Summary of the Invention

[0005] 1. Technical problems to be solved

[0051] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0052] Example 1

[0053] Currently, smart shopping carts (1) often use a continuous interlocking contact charging method to reduce space requirements and facilitate management. However, this method has certain drawbacks. When shopping carts (1) are not aligned, or when they are tilted to a certain extent relative to each other or to the charging station (2), the contact area of ​​the metal contacts becomes insufficient, increasing the resistance between the contacts and causing the temperature of the metal contacts to rise. If the temperature of the metal contacts reaches the melting or ignition point of the ABS material surrounding them, the ABS material may melt, deform, smoke, or catch fire, leading to an accident. Therefore, when using continuous interlocking contact (plug-in) charging for smart shopping carts (1), it is essential to accurately know which charging station (2) the smart shopping cart (1) is charging at and its sequence number. If an abnormality is detected, an emergency procedure should be immediately activated, disconnecting the power supply circuit of either the charging station (2) or the smart shopping cart (1) based on pre-defined logic. Current technologies often only address problems after they occur or rely on manual checks, resulting in low timeliness and safety. While most existing smart shopping carts 1 are equipped with wireless communication modules and can transmit their own identification code information to the backend system, when the smart shopping cart 1 uses continuous interlocking contact (socket-type) charging, due to user usage, when a specific shopping cart 1 returns to the charging position, the system, relying solely on the wireless communication module, even with the addition of a positioning module, cannot determine which cart 1 is in a row or group of shopping carts 1 due to positioning accuracy issues. It also cannot determine which charging station 2 the smart shopping cart 1 is charging on or its sequence number. Therefore, other methods and devices are needed to determine which charging station 2 the smart shopping cart 1 is charging on and what its sequence number is, to facilitate subsequent security management.

[0054] This solution combines the structure of the continuously interleaved contact shopping cart 1 system with the structure of the charging pile 2 to construct a method and system that can quickly obtain the corresponding charging identity and respond quickly to problems, such as cutting off power or triggering an alarm.

[0055] In this implementation application, the charging pile 2 can identify the identity code of each smart shopping cart 1 when it is charging, based on the identity code information transmitted during charging. This allows the charging pile 2 to accurately determine which charging pile 2 the smart shopping cart 1 is charging at and its sequence number. Once the main control system detects an abnormal charging of the smart shopping cart 1, it can quickly cut off the power supply circuit of the charging pile 2 or the smart shopping cart 1 according to the judgment logic, ensuring the safety of the plug-in charging process of the smart shopping cart 1.

[0056] This solution includes a corresponding charging pile system (2), a shopping cart bottom compartment system (1), an identification code, a control panel (3), and an image acquisition device (4). The bottom compartment system is located at the bottom of the shopping cart frame (1). Figure 1 , 2 As shown, several shopping carts 1 are connected in a plug-in manner, and the bottom compartments of the corresponding shopping carts 1 are also connected in sequence. The bottom compartment of the first shopping cart is connected to the charging station 2 for charging.

[0057] The shopping cart 1 in this solution is a smart shopping cart 1. Existing smart shopping carts 1 generally have a corresponding control panel 3 and a corresponding image acquisition device 4 set on the upper part and frame of the shopping cart 1. The specific location can be set according to the needs, and is not limited to the upper part and the frame. The control panel 3 and the image acquisition device 4 can be integrated or separate. As shown in the figure, the image acquisition device 4 is set on the back of the control panel 3 and is integrated with the control panel 3. The control panel 3 receives the information collected by the image acquisition device 4. Our image acquisition device 4 can be any device that can perform image acquisition, such as a camera. Each shopping cart 1 has a unique identification code. Each cart 1 has a different code to prevent confusion. This code can be a QR code or other type of identification pattern. Generally, the image acquisition device 4 of a subsequent shopping cart 1 can capture the identification code of the previous cart, obtain the corresponding image information, process it through the control panel 3, and then bind it, recognizing that the current shopping cart 1 is connected to the previous cart 1. Similarly, each charging station 2 has an identification code to identify the corresponding numbered charging station 2. The first shopping cart 1 connected to a charging station 2 can capture the identification code of the charging station 2 through the acquisition device, obtain the corresponding image information, process it through the control panel 3, obtain the charging station 2's number information, and bind it, recognizing that the current shopping cart 1 is connected to this charging station 2. Subsequent shopping carts 1 will also connect and charge at this charging station 2. The location of the image acquisition device 4 is not limited; it can be located anywhere that can capture the identification code. The identification code for shopping cart 1 can be a paper sticker affixed to shopping cart 1, or it can be generated by control panel 3 and displayed on the screen. This embodiment uses screen display of the identification code. Similarly, the identification code for charging pile 2 can be a paper sticker affixed to charging pile 2, or it can be generated by the control device of charging pile 2 and displayed on the screen. This embodiment also uses screen display of the identification code. The specific method can be selected according to whether charging pile 2 has a screen and the requirements.

[0058] The base system of this solution includes corresponding charging devices and corresponding front and rear charging panels. Charging pile 2 is also equipped with corresponding charging panels, such as... Figure 2As shown, the charging station 2 has a charging panel and the front and rear panels of the bottom compartment system. The panels are mutually compatible. The center of the contact panel has a magnetic attraction device, which is shown here as a cast iron block, but it can also be an electromagnet. The two sides of the magnetic attraction device are power output contacts for connecting the charging circuit. The front panel of the shopping cart bottom compartment is connected to the panel of the charging station 2, and the rear panel of the shopping cart bottom compartment is connected to the front panel of the next shopping cart bottom compartment. The magnetic attraction devices of the corresponding connected shopping cart bottom compartment front panels are matched with each other and can be set according to needs. If one side is an electromagnet and the other side is a cast iron block, when the shopping cart 1 is in contact with the charging station 2, due to the power supply, the electromagnet is energized and attracts the cast iron block, and the shopping cart 1 is fixed on the charging station 2. When the power is turned on, the electromagnet is energized and attracts the cast iron block, and the next shopping cart 1 is fixed on the previous shopping cart 1, which can be charged accordingly. The front and rear panels of each shopping cart bottom compartment system will be connected accordingly to ensure smooth charging. The specific positions of each part on the panel can be set according to requirements. For example, the magnetic device can be set on the side or the top, and the positive and negative terminals of the power contact can be set on one side. As long as the front and rear panels can correspond, there are no specific position restrictions.

[0059] The bottom storage system includes various necessary sensors, such as temperature sensors, to transmit essential data to the control panel 3. This essential data includes corresponding charging data, as well as one or more information such as voltage, current, and temperature. In the event of a short circuit or overheating, the system sends necessary data to the control panel 3, which in turn sends it to the corresponding backend control system to identify the shopping cart number and location, and to perform relevant emergency procedures. Information from the bottom storage system can be transmitted to the control panel 3 via wired or wireless means, depending on the design requirements.

[0060] In practice, after installation, charging station 2 displays an identification code containing its unique identifier. When smart shopping cart 1 is charging, its own identification code is displayed on control panel 3. When smart shopping cart 1 comes into contact with charging station 2, it uses its camera to capture the identification code on the charging station 2. Smart shopping cart 1 identifies itself by reading the information contained in the identification code. Simultaneously, smart shopping cart 1 displays its own identification code on control panel 3. Then, the identification codes of smart shopping cart 1 and charging station 2 are uploaded to the backend system.

[0061] When a subsequent smart shopping cart 1 comes into contact with the preceding smart shopping cart 1 for charging, the camera of the following smart shopping cart 1 identifies the identification code displayed on the control panel 3 of the preceding smart shopping cart 1. After reading the information, the following information is uploaded to the backend system: the identification code of the following smart shopping cart 1 and the identification code of the preceding smart shopping cart 1.

[0062] The backend system binds and sorts the identification codes of charging piles 2 and smart shopping cart 1 based on the information uploaded by smart shopping cart 1. If a smart shopping cart 1 using plug-in charging experiences an anomaly during charging, such as a short circuit or overheating, the system sends necessary data to control panel 3 via the bottom storage system. This data is then sent to the corresponding backend control system to identify the corresponding shopping cart 1 number and location, obtain the location of the associated charging pile 2, and determine the specific cart number, allowing for appropriate emergency handling. The system can accurately determine which charging pile 2 the malfunctioning smart shopping cart 1 is on, its sequence number, and thus take appropriate action.

[0063] Example 2

[0064] Example 2 is basically the same as Example 1, except that the identification code in Example 1 is the unique identification code of the shopping cart 1 of the charging station 2, so it can be displayed on a paper label or screen because the label is unique. Example 2 differs from Example 1 in that the corresponding shopping cart 1 identification code includes the identification code information as well as the aforementioned charging station 2, sequence, and other information. This information changes depending on the sequence number of the shopping cart 1 on the charging station 2 and its position on that charging station 2. Therefore, in Example 2, the shopping cart 1 identification code cannot be a paper label and must be displayed on a screen. Of course, this implementation method contains more information in the identification code, resulting in faster background transmission and processing speeds.

[0065] Specifically, for example, charging pile 2 generates unique identification information. The first shopping cart 1 collects the identification code through image acquisition device 4. Control panel 3 combines the identity and sorting code information of shopping cart 1 with the identity code information of charging pile 2 to generate its own identification code. The wireless communication module uploads the identity and sorting code information of smart shopping cart 1 and the identity code information of charging pile 2 to the backend system. The backend system binds and stores the identity code of charging pile 2, the identity code of shopping cart 1, and the serial number based on the received information. When the next smart shopping cart 1 enters the charging area of ​​the previous shopping cart 1, the next shopping cart 1 turns on the camera on control panel 3 to photograph the identification code displayed on the tablet of the previous smart shopping cart 1, obtaining the identity code information of the previous smart shopping cart 1. At the same time, the smart shopping cart 1 system generates an identification code containing its own code information, sorting code information, and charging pile 2 identity code information, and displays it on the screen of the tablet of shopping cart 1. Then, the identity and sorting code information of smart shopping cart 1 and charging pile 2 identity code information are uploaded to the backend system through the wireless communication module. The backend system uses the received information to bind and store the identification code of charging pile 2 and the identification code and serial number of shopping cart 1. This process is repeated sequentially.

[0066] The method used in the embodiment can accurately determine which charging station 2 the shopping cart 1 is charging on and what its order is. Combined with other information, if the charging of the shopping cart 1 is abnormal, the power supply circuit of the charging station 2 or the shopping cart 1 can be precisely disconnected through the control module, thus ensuring the charging safety of the continuously interleaved contact charging smart shopping cart 1.
