Description

TECHNICAL FIELD

[0002] With the development of the information age, more and more industries have entered the era of intelligence, and at present, supermarkets are also innovating intelligence to adapt to the development of the times. Traditional shopping carts are increasingly difficult to meet the needs of smart supermarkets, and will be gradually eliminated in the future, while new intelligent shopping carts will gradually replace them.

[0003] At present, intelligent shopping carts mostly adopt a charging method of inserting a plug, and one charging pile can charge multiple intelligent shopping carts at the same time, which is convenient and fast. However, when the intelligent shopping cart adopts the plug-in charging method, if the metal contact is not in good contact, it will cause the temperature of the metal contact to be too high, and once the temperature reaches the melting point or ignition point of the material wrapped around the metal contact, it is easy to cause an accident. Therefore, the real-time safety of the intelligent shopping cart when using the plug-in charging method is particularly important. In the prior art, the relevant risk information is generally identified through temperature control and other information, but there is no complete safety management method suitable for the field of shopping carts in the field of intelligent shopping carts.

[0046] The application will be described in detail below in conjunction with the drawings and specific embodiments.

[0047] Embodiment 1

[0048] For the above-mentioned target safety of the charging pile, the present scheme has a complete set of charging safety management system, equipment and corresponding method. At present, in order to reduce the occupied space and facilitate management when charging the intelligent shopping cart, the continuous interpenetration contact type charging mode is often used. However, this charging mode also has certain disadvantages. When the shopping carts are not arranged in line, the shopping carts and the charging piles are inclined to a certain extent, which will cause the insufficient contact area of the metal contacts for charging, the increased impedance between the metal contacts, and the temperature rise of the metal contacts. When the temperature of the metal contacts rises to the melting point or ignition point of the ABS material wrapped around the metal contacts, the ABS material will melt and deform or burn, resulting in a safety accident. Therefore, when the intelligent shopping cart uses the continuous interpenetration contact type (sleeve insertion type) charging, it is necessary to detect the power consumption of the charging pile and the intelligent shopping cart and the temperature information of the charging metal contacts in real time. Once the charging pile and the intelligent shopping cart are found to be abnormal, the emergency program is started immediately, and the power supply circuit of the charging pile or the power supply circuit of the intelligent shopping cart is disconnected according to the set logic.

[0049] In this embodiment, by installing a data acquisition module on the charging pile and the intelligent shopping cart, the power consumption and the temperature of the charging contacts during charging of the charging pile and the intelligent shopping cart are monitored in real time. Once an abnormality is found, the charging is stopped in time, and the safety of the intelligent shopping cart charging process is improved. Figures 1-4 As shown in the figure, an intelligent shopping cart charging safety management system includes a shopping cart control module and a charging pile control module,

[0050] Shopping cart control module:

[0051] The shopping cart main control module, i.e. the data processor, is responsible for processing the collected data information, making judgments, and communicating with the background system through the communication module;

[0052] The shopping cart switch module is used to turn the smart shopping cart's own charging circuit on and off.

[0053] The shopping cart communication module is used for communication between the main control module and the backend system;

[0054] The shopping cart data acquisition module includes a power consumption acquisition module and a temperature acquisition module, which are responsible for collecting the charging power consumption of the smart shopping cart and the temperature information of the metal contacts, respectively.

[0055] Charging pile control module:

[0056] The charging pile main control module, also known as the data processor, is responsible for processing the collected data information, making judgments, and communicating with the backend system through the communication module.

[0057] The charging pile switch module is used to turn the main charging circuit of the smart shopping cart on and off.

[0058] The charging pile communication module is used for communication between the main control module and the back-end system;

[0059] The charging pile data acquisition module is responsible for collecting power consumption and temperature information of the charging circuit and metal contacts of the charging pile.

[0060] In actual operation, when the charging station provides power to the smart shopping cart, it collects power consumption information and charging contact temperature information through its built-in data acquisition module. Based on the set threshold, once the power consumption or temperature reaches the threshold, corresponding safety measures are taken to ensure charging safety.

[0061] When using a plug-in charging method, the smart shopping cart collects information such as charging power consumption and charging contact temperature through its built-in data acquisition module. Based on the set thresholds, once the power consumption or temperature reaches the threshold, corresponding safety measures are taken to ensure charging safety.

[0062] Both the charging station and the shopping cart send relevant information to the backend system. The backend system judges based on threshold settings. When the threshold is reached, the backend system sends relevant information to the charging station and shopping cart, controlling the corresponding charging station switch module and shopping cart switch module to disconnect the circuit. This is all done through the main control module. The main control module for the charging station is usually located inside the charging station, while the main control module for the shopping cart is usually the control panel of the shopping cart.

[0063] In this embodiment, when the smart shopping cart is being charged via a plug-in method, the charging station and the smart shopping cart use a data acquisition module to monitor the power consumption and temperature of the charging station and the smart shopping cart in real time. If any abnormality is detected, the charging of the smart shopping cart will be cut off in time and an alarm will be triggered, thereby improving the safety of the smart shopping cart using the plug-in charging method.

[0064] The corresponding solution consists of a corresponding device, which includes a charging station and a shopping cart, and includes the system as described above.

[0065] like Figure 5 , 6 As shown in the figure, this application provides a method for safe charging management of smart shopping carts.

[0066] The first step is to connect the shopping cart to the charging station and the charging line of the shopping cart, and bind and sort the smart shopping cart's identification code with the charging station's identification code.

[0067] When the smart shopping cart is charging via a plug-in method, the smart shopping cart turns on the camera on the control panel to photograph the QR code containing the identity information of the vehicle in front or the charging pile. After obtaining the identification code information, it is uploaded to the back-end system via WIFI network. The back-end system determines which charging pile the smart shopping cart is bound to and its order on that charging pile based on the received information.

[0068] The second step involves the data acquisition module of the shopping cart and charging station monitoring the power consumption and temperature of the metal contacts of the charging station and smart shopping cart in real time during charging.

[0069] When the smart shopping cart is charging at the charging station, the main control module on the smart shopping cart and the charging station obtains its own power consumption and the temperature information of the metal contacts through the data acquisition module.

[0070] The third step is to make a judgment based on the collected power consumption and temperature information.

[0071] The main control unit of the charging pile acquires real-time power consumption and metal contact temperature information through a data acquisition module. When power consumption and temperature are within the normal range, the charging pile supplies power normally. When power consumption and temperature exceed the threshold, the charging pile shuts down the charging circuit through the control unit. The threshold can be set according to requirements.

[0072] The main control module of the smart shopping cart acquires real-time power consumption and metal contact temperature information during charging via a data acquisition module and sends it to the backend control system. When power consumption and temperature are within normal ranges, the smart shopping cart charges normally. When power consumption and temperature exceed thresholds, the smart shopping cart controls the switch module via its control module to shut down the charging circuit. Because it recognizes the corresponding charging station information, it can quickly determine which charging station the shopping cart is on. The backend system sends a cut-off message to the charging station's main control module, which then controls the charging station's switch module to shut down the charging circuit. This ensures the entire charging line is fully charged, guaranteeing overall safety.

[0073] Preferably, an alarm module is also included. This alarm module is installed in the backend system, which directly sends alarm information to the administrator. Alternatively, it can be installed in the charging pile system and / or shopping cart module. The backend system sends a cut-off message to the alarm module, which then sounds an alarm or displays an alarm message to alert staff to take appropriate action.

[0074] To accurately identify the locations of shopping carts and charging stations, this solution employs the following approach:

[0075] This solution designs an identification code, and each shopping cart is equipped with an image acquisition device. Existing smart shopping carts typically have a control panel and image acquisition device located on the top and frame of the cart. The control panel actually includes the shopping cart control module mentioned above. The specific location can be set according to needs, and is not limited to the top or the basket. The control panel and image acquisition device can be integrated or separate. As shown in the figure, the image acquisition device is located on the back of the control panel and is integrated with it. The control panel receives information collected by the image acquisition device, which can be any device capable of image acquisition, such as a camera. Each shopping cart has a unique identification code, ensuring each cart is unique and preventing confusion. This code can be a QR code or other type of identification pattern. Generally, the image capture device on a subsequent shopping cart can capture the identification code of the previous cart, obtain its image information, process it through the control panel, and then bind it to the previous cart, recognizing it as connected to the previous cart. Similarly, each charging station also has an identification code to identify its corresponding charging station. The first shopping cart connected to a charging station can capture the charging station's identification code, obtain its image information, process it through the control panel, and then bind it to that charging station, recognizing it as connected to that station. Subsequent shopping carts will connect and charge at the same charging station. The location of the image capture device is not limited; it can be placed anywhere that can capture the identification code. The shopping cart's identification code can be a paper sticker affixed to the cart, or it can be generated by the control panel and displayed on the screen. This embodiment uses a screen-displayed identification code. Similarly, the charging station's identification code can be a paper sticker affixed to the charging station, or it can be generated by the charging station's control device and displayed on the screen. This embodiment also uses a screen-displayed identification code. The specific method can be chosen based on whether the charging station has a screen and the specific requirements.

[0076] After installation, the charging station displays an identification code containing its unique identifier. When the smart shopping cart is charging, it displays another identification code containing its own unique identifier on the control panel. When the smart shopping cart comes into contact with the charging station, its camera captures the identification code on the station, and the cart identifies the station by reading the information contained within the code. Simultaneously, the smart shopping cart displays its own unique identifier on the control panel. Then, both the smart shopping cart's and the charging station's identification codes are uploaded to the backend system.

[0077] When a subsequent smart shopping cart comes into contact with the preceding smart shopping cart for charging, the smart shopping cart's camera identifies the identification code displayed on the control panel of the preceding smart shopping cart. After reading the information, the smart shopping cart uploads its own identification code and the identification code of the preceding smart shopping cart to the backend system.

[0078] The backend system binds and sorts the charging station's identification code with the smart shopping cart's identification code based on the information uploaded by the smart shopping cart. If a smart shopping cart using plug-in charging experiences an anomaly during charging, such as a short circuit or overheating, the system sends necessary data to the control panel via the storage compartment system. This data is then sent to the corresponding backend control system to identify the shopping cart's number and location, obtain the location of the associated charging station, and determine the specific cart's number, allowing for appropriate emergency handling. The system can accurately determine which charging station and sequence number the malfunctioning smart shopping cart is at, enabling the implementation of appropriate measures.

[0079] Example 2

[0080] 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 at the charging station, 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 identification code includes the identification code information as well as the aforementioned charging station and sequence information. This information changes depending on the sequence number of the charging station the shopping cart is at and its position on that charging station. Therefore, in Example 2, the shopping cart 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 backend transmission and processing speeds.

[0081] The invention and its embodiments have been described above illustratively. This description is not restrictive, and the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
