Detailed ways

In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Usually, when people consume in a catering consumption place, they need to order. A common ordering method is that the staff of the restaurant sends the menu to the user, and the order is completed through the records of the staff. With the development of the Internet, there are many ways of self-ordering, for example, ordering by scanning a QR code. The QR code binds the user to the table number of the table where they are located, and enters the corresponding ordering interface by scanning the QR code. The user can select the corresponding menu according to the displayed menu information, thereby reducing the phenomenon of queuing for ordering.

However, the method of ordering by scanning the QR code mainly relies on network communication. In the case of good network conditions, the menu information can be quickly loaded and the order information can be submitted; if the network condition is poor or Unstable network will affect the display of the menu and the submission of the user's order information, which will affect the user's dining experience. The inventor found in the research that ordering can be done through Bluetooth to avoid the influence of the network on ordering. The Bluetooth Serial Port Profile (SPP) protocol is a Bluetooth protocol, and the stack of the protocol may refer to FIG. 1 , which shows a schematic diagram of the stack of the Bluetooth SPP protocol. Among them, the baseband, Link Manager Protocol (LMP) and Logical Link Control and Adaptation Protocol (L2CAP) in Figure 1 correspond to the Open System Interconnection Reference Model (Open System Interconnection Reference). Model, OSI) of the first and second layers. RFCOMM is a Bluetooth adaptation layer protocol that provides a transport layer for the upper analog serial port. The Service Discovery Protocol (SDP) is an auxiliary protocol. The Serial Port API is a real analog serial port, which is provided to the application layer to call. The SPP protocol itself does not limit the format of the communication content, which can include pure data, audio, pictures, videos, and so on. Therefore, it can be used in restaurant ordering. When the user enters the restaurant, various data, such as menu data, can be directly transmitted. Since the Bluetooth connection is not affected by the network, the menu and order data are transmitted through Bluetooth. It can meet various ordering needs of users, including urging orders, adding orders, etc.

Therefore, the inventor proposes the ordering method of the present application, through which the user terminal establishes a Bluetooth connection with the merchant terminal according to the received Bluetooth broadcast message broadcast by the merchant terminal; after the connection is established, the menu data pushed by the merchant terminal is received. , and display the menu data; receive an order instruction from the user based on the menu data, generate order information, and send the order information to the merchant terminal for ordering. The mobile terminal and the merchant terminal are connected by bluetooth in the way of bluetooth connection, so as not to be affected by the network conditions, the connection stability of ordering is enhanced, and the dining experience of the user is improved.

Please refer to FIG. 2 . FIG. 2 shows an application scenario diagram applicable to the ordering method provided by the embodiment of the present application, including a user terminal 110 and a merchant terminal 120 . The user terminal 110 and the merchant terminal 120 are connected through Bluetooth, and the Bluetooth protocol adopted is the Bluetooth Serial Port Profile (SPP) protocol, wherein the SPP protocol itself does not have any restrictions on the format of the communication content, and can include pure data , audio, picture, video, etc.

The user terminal 110 may be an electronic device with a Bluetooth SPP protocol and a payment function, such as a mobile phone and a tablet computer, and a payment account pre-bound by the user is stored in the user terminal 110 . The merchant terminal 120 may be a computer, a cash register and other devices with a display function and a broadcast Bluetooth function. In this application scenario, the merchant terminal 120 can continuously broadcast the Bluetooth message, and when the user terminal 110 enters the radiation range 121 of the merchant terminal 120 broadcasting the Bluetooth message, it can receive the Bluetooth message broadcast by the merchant terminal 120, and according to the The Bluetooth message is connected to the merchant terminal 120 . Wherein, the dotted box 121 around the merchant terminal in FIG. 1 represents the coverage of the Bluetooth message broadcast by the merchant terminal 120 . When the user terminal 110 enters the range of the dotted box 121 , it can receive the Bluetooth message broadcast by the merchant terminal 120 .

Based on the above-described system and system operation process, the following will describe in detail the ordering method, device, electronic device, and storage medium provided by the embodiments of the present application through specific embodiments.

The embodiments of the present application will be described in detail below.

Referring to FIG. 3 , an embodiment of the present application provides a method for ordering meals, which can be applied to a user terminal. This embodiment describes the step flow on the user terminal side. The specific method may include:

Step S110: Establish a Bluetooth connection with the merchant terminal according to the received Bluetooth broadcast message broadcast by the merchant terminal.

The Bluetooth broadcast message is a broadcast message sent by the merchant terminal according to a preset frequency. When the user terminal enters the radiation range of the Bluetooth broadcast message broadcast by the merchant terminal, the Bluetooth broadcast message broadcast by the merchant terminal can be received. When the user terminal receives the Bluetooth broadcast message, it can establish a Bluetooth connection with the merchant terminal according to the Bluetooth broadcast message.

Specifically, the Bluetooth broadcast message may carry a connection request. When the user terminal receives the Bluetooth broadcast message, it parses the connection request carried in the Bluetooth broadcast message, responds to the connection request, and sends a message to the merchant. The terminal sends a confirmation connection response to complete the Bluetooth connection. After the user terminal and the merchant terminal establish a Bluetooth connection, it means that the user terminal and the merchant terminal can transmit data through the Bluetooth protocol. The Bluetooth protocol can be the SPP protocol, and the SPP protocol itself does not limit the format of the communication content. , which can be pure data, audio, picture, video, etc. In this way, menu data can be sent through the Bluetooth SPP protocol, and the menu data can be simple text or a menu with pictures, etc., so as to realize various display modes of the menu.

Step S120: Receive the menu data pushed by the merchant terminal, and display the menu data.

After the user terminal establishes a Bluetooth connection with the merchant terminal, the user terminal may receive menu data sent by the merchant terminal through the Bluetooth protocol. When receiving the menu data, the user terminal may analyze the menu data to display the menu data. It can be understood that, if the menu data sent by the merchant terminal through the SPP protocol is simple text information, then the user terminal parses the menu information and displays it as simple text information; If the menu data is picture information, then what the user terminal parses the menu information for display is picture information; if the menu data sent by the merchant terminal through the SPP protocol is video information, then the user terminal parses the menu information for display. Also for video information.

Step S130: Receive an ordering instruction from the user based on the menu data, generate ordering information, and send the ordering information to the merchant terminal for ordering.

After the user terminal parses and displays the menu information pushed by the merchant terminal, the user can select dishes through the displayed content to generate corresponding order information. For example, according to the displayed content, the user selects one dish each of Yuxiang Shredded Pork, Mapo Tofu, Kung Pao Chicken, and two pieces of rice, then the generated order information can be Yuxiang Shredded Pork x1, Mapo Tofu x1 x1, Kung Pao Chicken x1, Rice x2. After the order information is generated, the user terminal can send the order information to the merchant terminal for ordering, so that the staff of the merchant can prepare dishes according to the order information.

The present application proposes a method for ordering meals. The user terminal establishes a Bluetooth connection with the merchant terminal according to the received Bluetooth broadcast message broadcast by the merchant terminal; after the connection is established, the menu data pushed by the merchant terminal is received, and the The menu data is displayed; the user's ordering instruction based on the menu data is received, the ordering information is generated, and the ordering information is sent to the merchant terminal for ordering. The user terminal is connected with the merchant terminal through Bluetooth connection, so as not to be affected by the network conditions, the connection stability of ordering is enhanced, and the user's dining experience is improved.

Referring to FIG. 4 , another embodiment of the present application provides an ordering method. Based on the foregoing embodiments, this embodiment focuses on the process of ordering and payment at a user terminal. The method may include:

Step S210: Establish a Bluetooth connection with the merchant terminal according to the received Bluetooth broadcast message broadcast by the merchant terminal.

For step S210, reference may be made to the corresponding parts of the foregoing embodiments, and details are not described herein again.

Step S220: Receive the menu data pushed by the merchant terminal, and analyze the menu data to obtain layout information and dish information.

When the menu data pushed by the merchant terminal is received, since the menu data is transmitted through the SPP protocol, the menu data needs to be parsed. Among them, the simple text menu includes text and text arrangement. In order to make the menu displayed to the user more abundant, it usually includes pictures, text explanations of the corresponding pictures, prices and other information, then these pictures and texts need to be arranged in a certain way so that they can be displayed to the users. Among them, if the dish information is a plain text menu, the layout information can be arranged from right to left, that is, the text reading order is from right to left, or the layout is from left to right, that is, the text reading order From left to right; if the dish information is the dish image plus text information, the typesetting information can be that the text information is below the dish image, or the dish text information is to the right of the dish image. Then, by parsing the menu data at the user terminal, dish information and corresponding layout information can be obtained.

Step S230: Display the dish information according to the layout information.

After analyzing the menu data, the user terminal can display the dish information according to the typesetting information according to the dish information and layout information obtained by the analysis. For example, if the typesetting information obtained by parsing the menu data is that the text information is below the picture of the dish, then the menu data displayed on the user terminal may refer to FIG. On the display interface of the user terminal 110, the explanation and price 112 corresponding to the dishes 111 and the dishes are displayed; if the typesetting information obtained by parsing the menu data is text information on the right side of the image of the dishes, the menu data displayed on the user terminal can refer to FIG. 6 is a schematic diagram of displaying another menu data provided in an embodiment of the present application, wherein, on the display interface of the user terminal 110 , an explanation and a price 112 corresponding to the dishes 111 are displayed. Thus, the user can view the dish data on the user terminal for the user to select.

Step S240: Receive an ordering instruction from the user based on the menu data, generate ordering information, and send the ordering information to the merchant terminal for ordering.

Based on the display interface shown in Figures 5 and 6 above, the user can select the corresponding menu on the display interface. After the user confirms the selected menu, order information will be generated, and the user terminal will pass the order information through the SPP. The protocol sends the order information to the merchant terminal for ordering. The order information may include information such as the dishes ordered by the user, the user's account, and the price of the dishes. The user's account may be a payment account; it may also be another account bound to the payment account, such as a social account; it may also be an identity identifier of the user terminal, and the like.

Step S250: Receive billing information generated by the merchant terminal according to the ordering information.

After the user terminal sends the order information to the merchant terminal, it can receive bill information generated by the merchant terminal based on the order information for the user to pay the bill. The billing information may include the total amount of dishes that the user needs to pay and other information. The other information includes the dishes ordered by the user, the amounts of various dishes, the merchant's payment account, and the like.

In some implementations, a user may initiate a checkout request through the user terminal, the user terminal may send a checkout request to the merchant terminal, and when the merchant terminal receives the checkout request, it will generate a bill according to the order information The information is sent to the user terminal for the user to pay the bill.

In other implementations, after the user terminal sends the order information to the merchant terminal, the merchant terminal may generate billing information according to the order information at a preset time interval and send it to the user terminal, and the user terminal will After the order information is sent, the bill information generated by the merchant terminal according to the order information is received at preset time intervals. For example, if the preset time is 3 minutes, then 3 minutes after the user terminal generates order information according to the user's order instruction and sends it to the merchant terminal, the bill information generated by the merchant terminal according to the order information can be received.

Step S260: After receiving the payment operation according to the billing information, send payment information to the merchant terminal, where the payment information is used to instruct the merchant terminal to confirm the payment operation.

After receiving the billing information, the user terminal can make payment for the billing information, wherein the user terminal stores a payment account pre-bound by the user, for example, a WeChat payment account, an Alipay account, and the like. Then, when the user performs a payment operation on the billing information, the corresponding amount needs to be deducted from the payment account pre-bound in the user terminal.

In one embodiment, the user terminal may initiate a deduction request to the server corresponding to the payment account, where the deduction request includes the payment account, the deduction amount, and the collection account. When the server receives the deduction request , send a confirmation instruction to the user terminal, after the user confirms that there is no problem with the payment account, the deduction amount and the collection account, he can complete the deduction by entering a password or entering a fingerprint, and the server will send the corresponding amount to the collection. account number.

In another embodiment, if the network condition of the environment where the user terminal is located is poor and it is difficult to establish a network connection with the server, the user terminal can encrypt the debit request and send it to the merchant terminal through a Bluetooth connection, instructing the merchant terminal to A chargeback request is sent to the server. The merchant terminal sends the encrypted debit request to the server. After decrypting the deduction request, the server sends an encrypted confirmation instruction to the merchant terminal, and instructs the merchant terminal to send it to the user terminal. The merchant terminal sends the encrypted confirmation instruction to the user terminal, and the user terminal displays information such as the payment account number, the debit amount, and the collection account number according to the confirmation instruction. Enter your password or enter your fingerprint to confirm the deduction operation. The user terminal encrypts the password entered by the user or the entered fingerprint and sends it to the merchant terminal, and instructs the merchant terminal to send it to the user terminal. The merchant terminal sends the encrypted password or fingerprint to the server. After the server decrypts the password or fingerprint and confirms that it is correct, it debits the payment account and sends the corresponding amount to the receiving account. It is understandable that the encryption method of the information by the user terminal is known to the server and can be decrypted, but the merchant terminal is unknowable and cannot be decrypted; the encryption method of the server to the information is known and decryptable by the user terminal, while the merchant terminal cannot. so it cannot be decrypted.

Step S270: Receive feedback information after the merchant terminal confirms the payment operation, and complete the payment.

After the user completes the payment operation through the user terminal, the merchant terminal can receive the amount corresponding to the billing information, and then the merchant terminal can return a feedback message to the user terminal to remind the user that the payment has been completed.

During the whole process, the user can also input the dining position through the user terminal at any time, then the user terminal can receive the dining position input by the user, and send the dining position and the input time of the dining position to the merchant terminal. Thus, the user can change his dining position according to his choice, and the staff of the restaurant can also know the user's dining position at any time. For example, when the user enters the restaurant for the first time, it is 9:00, and he enters his own dining position as table number 02, and the user terminal sends "table number 02-9:00" to the merchant terminal; after the user completes the ordering , and want to change his dining position to table number 05, then the user enters his dining position as table number 05 through the user terminal at 9:07, then the user terminal sends "table number 05-9:07" to the merchant terminal , the merchant terminal can determine the user's final dining position according to the dining position and time, so that the user can flexibly change his dining position to meet the user's dining needs.

Since the user terminal and the merchant terminal communicate through Bluetooth, the Bluetooth may be disconnected, or the user himself turns off the Bluetooth artificially, so the merchant cannot know the user's needs. Therefore, the connection state between the user terminal and the merchant terminal can be detected by detecting the Bluetooth connection state of the user terminal, so as to avoid the problem of interruption of communication between the user and the merchant. Specifically, please refer to FIG. 7, which shows the process of detecting the connection state of the user terminal. The method may include:

Step S310: Establish a Bluetooth connection with the merchant terminal according to the received Bluetooth broadcast message broadcast by the merchant terminal.

For step S310, reference may be made to the corresponding parts of the foregoing embodiments, and details are not described herein again.

Step S320: Detecting whether the Bluetooth connection is disconnected, if yes, execute step S330, if not, continue to execute step S320.

After the Bluetooth connection is established with the merchant terminal, it is possible to detect whether the Bluetooth is disconnected, if the user terminal detects that the Bluetooth connection is disconnected. It may be that the user actively disconnects the Bluetooth, or the Bluetooth connection is interrupted due to interference. If it is detected that the Bluetooth connection is disconnected, step S330 is performed; if it is not detected that the Bluetooth connection is disconnected, continue to detect whether the Bluetooth connection is disconnected.

In the embodiment of the present application, after the order is completed and the order information is obtained, this step may be performed at a certain frequency or in real time to monitor whether the Bluetooth connection is disconnected when the payment is not completed.

Step S330: If the corresponding order information has not been paid for, automatically connect with the merchant terminal via Bluetooth.

When the Bluetooth is disconnected, it can be determined whether the payment is completed corresponding to the order information. If the user has completed the payment for the corresponding order information when the Bluetooth is disconnected, no processing is performed; if it is detected that the user has a corresponding order If the payment is not completed for the information, there may be a situation of non-payment, and the Bluetooth connection with the merchant terminal is automatically performed.

If the user has the corresponding order information and fails to complete the payment, the user terminal automatically re-establishes a connection with the merchant terminal after receiving the Bluetooth broadcast message broadcast by the merchant, so that the merchant can respond to the user's needs and locate the user. In some embodiments, it is possible that the user disconnects the Bluetooth actively, and thus, the user terminal can no longer receive the Bluetooth broadcast message broadcast by the merchant terminal. Then, it can be detected whether the disconnection of the bluetooth is the receipt of the disconnection instruction from the user, and if the disconnection instruction from the user is detected, a payment instruction is performed to remind the user that there is still order information and the payment has not been completed.

In the ordering method proposed in the present application, the user terminal establishes a Bluetooth connection with the merchant terminal according to the received Bluetooth broadcast message broadcast by the merchant terminal; after the connection is established, the menu data pushed by the merchant terminal is received, and the The menu data is displayed; receiving the user's order instruction based on the menu data, generating order information, sending the order information to the merchant terminal for ordering, and receiving the order information sent by the merchant terminal according to the order information. Generated billing information, and make payment on the billing information. And users can input their own location information at any time to avoid binding the user with the dining location, so that the user can flexibly choose the dining location and improve the user's dining experience; the judgment of Bluetooth disconnection avoids the communication between the user and the merchant When it is detected that the user has not completed the payment of the order information, the user actively disconnects the Bluetooth connection, and a payment prompt is issued to reduce the phenomenon of non-payment, thereby improving the user's dining experience.

Referring to FIG. 8 , another embodiment of the present application provides a method for ordering meals, which can be applied to a merchant terminal. This embodiment describes the steps on the side of the merchant terminal. The specific method may include:

Step S410: The merchant terminal broadcasts a Bluetooth broadcast message according to a preset frequency, and the Bluetooth broadcast message is used to instruct the user terminal to establish a connection with the merchant terminal according to the Bluetooth broadcast message.

The merchant terminal can continuously broadcast the Bluetooth broadcast message, so that the user terminal entering the radiation range of the merchant terminal's Bluetooth broadcast message can receive the Bluetooth broadcast message. The Bluetooth broadcast message broadcast by the merchant terminal is affected by the power and the current environment, which will affect the receiving range. Usually, when the user terminal enters the range of 5 to 10 meters from the merchant terminal, the Bluetooth broadcast message broadcast by the merchant terminal can be received.

The merchant terminal may broadcast a Bluetooth broadcast message at a preset frequency, and the specific value of the preset frequency is not limited in the embodiments of the present application, and it is appropriate to enable any user terminal that enters the radiation range of the merchant terminal to respond quickly. .

Step S420: After the merchant terminal establishes a Bluetooth connection with the user terminal, push the menu data to the user terminal.

The Bluetooth broadcast message broadcasted by the merchant terminal may carry a connection request, the user terminal may send a connection confirmation response to the merchant terminal in response to the connection request, and the merchant terminal establishes a Bluetooth connection with the user terminal upon receiving the connection confirmation response. After the Bluetooth connection is established with the user terminal, the menu data of the merchant can be pushed to the user terminal, so that the user can view the menu and select dishes.

Wherein, the menu data may include dish information and corresponding layout information. Then, when the user terminal receives the menu data and analyzes the menu data, the menu data of the merchant can be displayed.

Step S430: Receive and display the order information based on the menu data sent by the user terminal.

After the merchant terminal pushes the menu data to the user terminal, the user terminal can select dishes according to the menu data. After the user completes the selection of the dishes, it can generate corresponding order information according to the dishes selected by the user and send it to the merchant. terminal, so that the merchant terminal can receive the order information and display it, and the staff can prepare meals for the user according to the displayed order information.

Wherein, after receiving and displaying the order information based on the menu data sent by the user terminal, it can also be judged whether the Bluetooth connection with the user terminal is disconnected; The terminal successfully establishes the connection, and sends out alarm information corresponding to the user terminal.

After the merchant terminal displays the order information, if the Bluetooth is disconnected, the communication with the user will be lost. Therefore, it can be determined whether the Bluetooth connection with the user terminal is disconnected, and if disconnection is detected, it is detected whether to re-establish a Bluetooth connection with the merchant terminal within a preset time, and if the connection is not successful within the preset time, Then, alarm information corresponding to the user terminal can be issued to prompt the staff of the merchant to handle it. If the Bluetooth connection with the user terminal is reconnected within the preset time, no alarm message will be sent. Specifically, after the user terminal and the merchant terminal are connected via Bluetooth, the merchant terminal can obtain information such as the identity identifier of the user terminal, so that the disconnected user terminal can be determined through the identity identifier of the user terminal.

In some scenarios, there may be a situation where the user does not pay after completing the order. Therefore, the distance between the user terminal and the merchant terminal can be detected in real time, and when the distance is greater than the preset distance, determine Whether the user terminal has completed the payment, if not, it will issue an alarm to instruct the staff to confirm the payment. Specifically, the distance between the user terminal and the merchant terminal can be obtained through the correspondence between the Bluetooth RSSI value and the distance. Generally, the farther the distance from the merchant terminal, the smaller the Bluetooth RSSI value. When the distance between the terminal and the merchant terminal is greater than the preset distance, confirm whether the user terminal has completed the payment, which may be to detect whether the merchant terminal has sent feedback information of successful payment to the user terminal, if the feedback information is not detected. is sent, an alarm message can be issued to instruct the staff to confirm the payment. The alarm information may be that the merchant terminal sends an alarm instruction to the user terminal that needs to be confirmed, instructing the user terminal to issue an alarm, or the merchant terminal may issue an alarm to prompt the staff to confirm payment.

This application proposes a method for ordering meals. A merchant terminal broadcasts a Bluetooth broadcast message according to a preset frequency, and the Bluetooth broadcast message is used to instruct a user terminal to establish a connection with the merchant terminal according to the Bluetooth broadcast message; the merchant terminal and the user After the terminal establishes the Bluetooth connection, the menu data is pushed to the user terminal; the order information based on the menu data sent by the user terminal is received and displayed.

If the Bluetooth connection is disconnected, it will automatically reconnect. It is not necessary to process when it is detected that the Bluetooth is disconnected. If the user does not complete the payment for the corresponding order information and fails to reconnect within the preset time, the cash register can send out a corresponding alarm message to prompt the staff to confirm artificially. If the user actively disconnects the Bluetooth, and If the payment of the corresponding order information is not completed, the user is prompted to pay. In some scenarios, the user may forget to pay for the order information, then the cash register can detect the distance between the mobile phone and the cash register, and when the distance is greater than the preset distance, an alarm will be issued to prompt the staff to confirm. It avoids the situation where no payment is made after the meal, and improves the user's dining experience.
