The door control device is controlled by a field controller and is used for driving an electric control door of a shop to open or close; the door control device is a motor driver which is connected with the door lock and controls the opening and closing of the door lock.

Further, the system also comprises a server which is in communication connection with the field controller.

The system has two modes, one is a member fee deduction mode; the other is the normal charging mode.

In the member fee deduction mode, a customer opens an account in a server, money is prestored in the account, the server transmits account information to a field controller in a wireless or wired mode, and after the field controller receives a plurality of account information, an identity authentication code set is formed locally on the field controller.

When a customer is in a shop, the mobile phone of the customer is in the receiving range of the Bluetooth communication module, the Bluetooth communication module establishes communication with the Bluetooth SIM card, and the Bluetooth SIM card carries encrypted user information.

The Bluetooth communication module decrypts the encrypted identity information at the Bluetooth SIM card side to obtain a decrypted identity authentication code, and transmits the identity authentication code to the field controller; the local storage module of the field controller is provided with an identity authentication code set, the identity authentication code is inquired in the prestored identity authentication code set, and if the corresponding identity authentication code is inquired, the customer is judged to be a member.

When the customer settles accounts, the commodity settlement device sends the order to the server, the server finds the account stored in the local server according to the customer identity authentication code, and the commodity charge is deducted from the account. After deduction is completed, the server sends information to the field controller, and the field controller opens the electric control door through the door control device.

Further, the payment system also comprises a two-dimensional code scanning box, wherein the two-dimensional code scanning box is electrically connected with the field controller, and the two-dimensional code scanning box is used for scanning the payment two-dimensional code.

Further, the commodity settlement device comprises a two-dimensional code scanning gun; the two-dimensional code scanning gun is used for scanning a bar code or a two-dimensional code on a code commodity, and a shopping list and payment amount are generated at the site controller.

And further, the system also comprises a display screen connected with the field controller, and the display screen is used for displaying the amount information.

The electronic label is attached to the outer package of the commodity and used for storing commodity information; the commodity information at least comprises a name, a price and a specification. The customer scans the electronic tag through the smart phone to know the commodity information.

And the electronic scale is electrically connected with the field controller and is used for weighing the commodities on the goods shelf and reflecting the weighing result to the field controller in real time. The weight loss represents the customer taking the goods away.

And further, the system also comprises a goods shelf for bearing the goods, wherein an infrared sensing device is further arranged on the goods shelf, and the infrared sensing device is used for sensing whether the goods are taken away in real time and sending a sensing result to the field controller.

When the infrared sensing device senses that the article is taken and the electronic scale detects weight change, the field controller compares the article detected by the infrared sensing device with the weight change detected by the electronic scale, if the comparison result is consistent, the commodity is taken away by a user, and the field controller sends a settlement instruction to the commodity settlement device; the commodity settlement device generates an order.

Further, a human body sensor is included, which is provided at an entrance and exit position of the shop, for detecting whether a person enters or leaves.

The system also comprises a monitoring module, wherein the monitoring module is used for monitoring the inside and the outside of the shop in real time and sending the monitoring video to the server in real time. The monitoring module is a camera.

The system further comprises a first NFC communication module, wherein the first NFC communication module is integrated in the field controller or is electrically connected with the field controller; after the first NFC communication module is in communication connection with the intelligent mobile terminal or the IC card integrated with the second NFC communication module, the field controller and the intelligent mobile terminal or the IC card can perform data interaction. The first NFC communication module establishes near field communication with the intelligent mobile terminal so as to carry out NFC payment.

Further, the Bluetooth SIM card is bound with the electronic account.

After the field controller and the intelligent mobile terminal can perform data interaction, if the authentication is not passed, the customer is not a member of the store, and the normal charging mode is entered.

In normal charging mode, when the user wants to pay, the SIM card sends the payment information to the banking system, which transfers the payment from the bound electronic account to the banking account controlled by the system server. And after receiving the payment, the server sends information to the field controller, and the field controller opens the electric control door through the door control device.

The system provides a new self-service purchase settlement system by using the Bluetooth SIM card in the intelligent mobile terminal, so that the intelligent mobile terminal which is provided with the Bluetooth SIM card but does not have the NFC function can also carry out non-contact payment; the system can realize 24-hour unattended self-service shopping, greatly saves the labor cost and achieves the benefit of convenience for people; the picking and placing and payment flow direction of the commodities can be monitored, and the commodities are prevented from being stolen; the system has the advantages of extremely wide application range, great saving of the application cost of mobile payment, extremely high payment safety, easy acceptance by users and merchants, easier popularization and application, higher popularization rate and contribution to market development, thereby achieving commercial success.

One characteristic of this scheme of adoption is based on bluetooth communication, but the distance of bluetooth communication is generally within 0-100 meters (according to the power size), therefore, in order to avoid a plurality of different bluetooth SIM cards to interact with the card reader (like the machine for punching the card of bus, the payment machine of shop, entrance guard's machine etc.) simultaneously, cause the communication confusion, can solve through multiple mode: mode 1: the card reader reduces the rf power (power for transmitting and receiving signals), for example, the rf power is reduced by designing or modifying the antenna (for example, using a specially-made smaller antenna), or the bluetooth main control chip controls the rf power, which is specifically the prior art. Mode 2: and a shielding box (shielding cover) is added to shield signals of other Bluetooth SIM cards, so that the Bluetooth SIM cards can only communicate with the mobile phone with the Bluetooth SIM cards in the shielding box at each time.

It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
