Description

A self-scanning code settlement device for shopping carts

technical field

The utility model relates to the field of intelligent technology, in particular to an autonomous code-scanning settlement device for shopping carts. Especially when there are many consumers in large shopping malls, and the cashiers are congested when the consumers buy many commodities, the shopping cart installed with the device can reduce the queuing time. It can also be used when merchants need to promote their own products, and the device can play advertisements along with the shopping cart. The device is suitable for large shopping malls, as well as small and medium-sized supermarkets where cashier counters may be congested during peak shopping hours.

Background technique

With the progress and development of our society, people are more and more inclined to shop in large shopping malls. "One-stop shopping" is one of the reasons why large shopping centers are so popular, and the products are clearly marked and classified for consumption, and electronic settlement can be realized, all of which will undoubtedly help reduce the time cost of purchasing. However, in the actual research, the contradiction of paying in long queues in supermarkets has become more and more prominent, and the promotion methods of enterprises sometimes fail to achieve the best results, which brings great troubles to consumers, supermarket operators and enterprises. The survey found that customers spend about 30 minutes to an hour each time they go shopping in the supermarket, and the time spent waiting in line to pay the bill accounts for more than 20% of the shopping time. Sometimes the time to wait in line is longer than the time to buy things. People began to complain that it was originally for convenience, but now it wastes a lot of time. Therefore, when asked whether they can accept the current waiting time in line to pay bills, 67% of consumers think they cannot. When asked whether they would experience blind shopping due to incomplete understanding of product information, 71% of consumers said they had such an experience. At the same time, 45% of the supermarket operators in the survey said that there will be at least three checkout congestions every month. On weekends and weekends, merchants have a dazzling array of promotional information, and consumers are often dazzled, so that good publicity effects cannot be achieved. Therefore, it is very necessary to design a device that can automatically scan codes and prompt product information, reduce queuing time to a certain extent, and facilitate enterprise publicity.

Utility model content

In order to solve the problems of long queues for checkout, incomplete understanding of product information by consumers, and ineffective promotion of products by merchants in supermarkets, the utility model provides: a self-scanning code settlement device for shopping carts. The device obtains the corresponding product information by scanning the bar code of the product, realizes automatic pricing, and plays the purchased product information and the merchant's promotional information through the display screen and the voice device.

The technical solution of the utility model to solve the above-mentioned problems is: to design a self-scanning code settlement device for shopping carts, which is characterized in that it includes a reset button, a code scanner, a confirmation button, a controller, a display screen, and a wireless transmission module , Voice module; wherein, the controller is respectively connected with the reset button, code scanner, confirmation button, display screen, wireless transmission module and voice module.

The controller is an embedded single-chip microcomputer, including various pins, wherein, the reset button, the confirmation button, the display screen and the voice module are connected to the I/O port pins respectively, and the code scanner and the wireless transmission module are respectively It is connected to its serial port communication pin; and, the wireless transmission module transmits information to an external computer through a wireless transmission mode.

The beneficial effects of the utility model are: after the reset button is pressed in the commodity barcode acquisition subsystem, the controller detects that the barcode scanner obtains the commodity barcode information and sends it to the controller for data matching, thereby judging the commodity. At the same time, the controller automatically accumulates commodity prices and stores them. Afterwards, the controller invokes the pre-stored product information data, and prompts through the display screen and voice. When the controller detects that the confirmation button is pressed, it will automatically send the accumulated price and the detected product information to the computer. In addition, the controller also plays other stored commodity information through the display screen and voice within a preset time. The utility model has the advantages of simple structure, convenient operation, low power consumption, and controllable switch. It can detect the input of commodity barcode information for a long time and take corresponding prompts, which greatly reduces the time of queuing and waiting for checkout, and prevents customers from shopping blindly. It facilitates the operation of supermarket operators and corporate publicity.

Detailed ways:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is described further.

The self-scanning code settlement device (device for short) used in the shopping cart of the present invention is characterized in that it includes a reset button 1, a code scanner 2, a confirmation button 3, a controller 4, a display screen 5, a wireless transmission module 6, and a voice module 7. Wherein, the controller 4 is respectively connected with the reset button 1, the code scanner 2, the confirmation button 3, the display screen 5, the wireless transmission module 6, and the voice module 7.

Described controller 4 is embedded single-chip microcomputer, comprises various pins, and wherein, described reset button 1, confirmation button 3, display screen 5 and speech module 7 are connected with its I/O port pin respectively, and described scanner 2 and the wireless transmission module 6 are respectively connected to their serial port communication pins; and, the wireless transmission module 6 transmits information to an external computer through a wireless transmission mode, and the whole device is powered by a 5V lithium battery.

The code scanner 2 is a laser code scanner, the model is Shangchen 558, and the manufacturer is Guangzhou Shangchen Electronics Co., Ltd.

The controller 4 is a Hetai 32-bit embedded micro-control chip, the model is HT32F1765, and the manufacturer is Hetai Semiconductor (China) Co., Ltd.

The display screen 5 is an LCD control module, its screen is a 320*240 dot matrix LCD screen, the model is ILI9341, and the manufacturer is Shenzhen Ruidawei Technology Co., Ltd.

The wireless transmission module 6 is a bluetooth communication module, the model is HC-05, and the manufacturer is Guangzhou Huicheng Information Technology Co., Ltd.

The voice module 7 is a TTS serial speech synthesis module, the chip model is SYN6288, and the manufacturer is Beijing Yuyin Tianxia Technology Co., Ltd.

The core of the device is the embedded microcontroller as the controller 4. The main function of the controller 4 is to determine which commodity the scanned commodity is, and it mainly relies on the barcode information collected from the scanner 2 for data matching. The reset button 1 is mainly used to update the existing information after opening the shopping cart. Pressing the button will cause the controller 4 to automatically clear the previously stored shopping information of the previous consumer; the code scanner 2 is mainly used to confirm the purchase The barcode information of the commodity is obtained, and the data is sent to the controller 4. The controller 4 compares the collected barcode information with the array information in the database. After the complete match, the commodity can be judged. In the controller 4 Accumulate the unit price of the product, and at the same time call out the prompt data corresponding to the product, such as unit price, manufacturer, precautions, etc. The display screen 5 and the voice module 7 mainly receive the control instructions from the controller 4 to prompt the information of the product, wherein the screen 5 can display pictures and text, and the voice module 7 can play the information to be prompted, which is mainly convenient for people with poor eyesight.
