Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The cash register system based on the fusion of the C/S and the B/S comprises: the system comprises a database platform, a double-screen cash register platform, a code scanning gun and a C/S server.

The database platform comprises a commodity database and a consumption database. The commodity database is used for storing commodity information. The consumption database is used for storing information related to consumption such as orders, bills, payment and the like.

The code scanning gun is used for scanning the commodity information and the payment information and sending the commodity information and the payment information to the main screen cash registering module.

The double-screen cashier platform comprises a main screen cashier module and an auxiliary screen display module. The main screen cashier module is provided for cashiers and can provide functions of logging in, displaying shop information, order information, payment information and the like. The auxiliary screen display module is provided for the consumer and can provide functions of displaying order information, payment information and the like.

The main screen cashier module and the auxiliary screen display module are realized based on a browser of a B/S mode, and the main screen cashier module and the auxiliary screen display module are communicated through a C/S server. The information interaction is carried out through the C/S communication, the main screen and the auxiliary screen respectively provide corresponding functions of a cashier and a customer, the more visual consumption amount of the customer is provided, the information interaction safety is improved, and the equipment development and maintenance cost is reduced.

Preferably, the main screen cashier module comprises a first communication module, a socket library is loaded in the first communication module, and the first communication module is used for establishing connection and communication with the C/S server; the auxiliary screen display module comprises a second communication module, a socket library is loaded in the second communication module, and the second communication module is used for establishing connection and communication with the C/S server; the C/S server is used for loading a socket library, creating a communication socket for the first communication module and the second communication module respectively, and binding the communication socket to the IP address and the port of the C/S server.

Preferably, the main screen cashier module further comprises a shop information display module and an order information display module. The shop information display module can visually display the shop turnover and the order number, and a corresponding detail page can be accessed by clicking the corresponding turnover or order small module. The order information display module can display the order information of the consumer. The cashier clicks a cash register button, enters a cash register page of the system, and pays for cash by scanning the code gun.

Preferably, the main screen cashier module comprises a user login module, and the user login module supports two modes of password authentication login and mobile phone number authentication login.

Fig. 1 is a schematic diagram of a user login process.

In the login module page, a cashier needs to input a user name and a password, and enters a mobile phone number verification code stage after the user name and the password are successfully matched with the password stored in the database platform. If the user name does not exist or the user name is input wrongly, the system prompts that the user name does not exist or the user name is input wrongly; if the password input is wrong, the corresponding password input is correspondingly prompted to be wrong.

The user login module of the embodiment of the invention is additionally provided with a mobile phone number verification mode, and is a protective measure which is added for preventing the login account number from being maliciously logged in by a non-business clerk and ensuring the personal benefit of the cashier.

Specifically, when the user name and the password input by the cashier are successfully matched with the system background, the mobile phone verification code stage is started, the cashier is not allowed to modify the mobile phone number in the mobile phone verification code stage, and the user name and the password are prevented from being not matched with the login user name. The cashier can successfully log in the cashier system by inputting a correct verification code according to the short message of the mobile phone.

Preferably, the user login module sends the password input by the user to the C/S server in the C/S communication mode for encryption. The login module also comprises a password remembering function, wherein the password remembering function abandons the mode of storing the account password by cookie of the browser in the original B/S mode, but clicks the remembered password through the communication mode of the C/S, sends the account password to the C/S terminal, and stores the account password through the file encryption processing of the C/S terminal. The original cookie mode is abandoned, so that the user information is prevented from being always stored in the browser end in the original cookie mode, if the expiration time is not set in the browser, the cookie is stored in the memory, and the life cycle is ended along with the closing of the browser; if the expiration time of the cookie is set in the browser, the cookie is stored in the hard disk, and after the browser is closed, cookie data still exist until the expiration time disappears. I.e. the day the saved user information will always disappear. And if the user deletes the cookie of the browser, the user logs in again and needs to refill the login related information. At the same time, the user may manipulate cookies on their computer, causing the cookies to be tampered with, which represents a potential risk to security. And the user information is always stored in the xml file through the C/S file storage, so that the user cannot modify the user information and the user information cannot disappear, and the C/S encryption avoids using a transmission protocol of a B/S plain text, thereby ensuring the safety of the account password.

The login module simultaneously sets the functions of forgetting the password and modifying the password.

Fig. 2 is a schematic flow diagram of cashier.

For example, a cashier enters a login page of the cash register platform, and first inputs a user name and a password to match the user name and the password. And entering a verification code stage after successful matching, clicking by a cashier to acquire the verification code, sending the verification code to the mobile phone of the user by the database platform, correctly inputting by the cashier through the received verification code, and finally clicking a login button to login the platform. If the cashier forgets the login password, the cashier can click the forget password button on the login page to enter a password modification stage. The password modification interface requires the cashier to input a modification password, and simultaneously input a confirmation password again according to the prompt of the page, if the passwords input twice are inconsistent, the system prompts that the passwords input twice are inconsistent, the passwords need to be input again, and only when the passwords input twice are consistent, the password modification can be successful, and the password modification interface returns to the login interface.

After the cashier logs in the cashier platform, the cashier enters a platform head page. The platform home page mainly shows the order quantity and turnover in the month and day. The method mainly comprises 4 small modules, the corresponding small modules are clicked to enter a corresponding list detail page, and the page mainly displays information such as order amount, order user mobile phone numbers and the like. While the page contains a de-pay button.

Specifically, when the consumer comes to a cash register, the cashier scans and reads the bar code of the commodity purchased by the consumer through the bar code scanning gun 100; the background of the cashier platform immediately acquires corresponding payment amount, when a plurality of commodities are purchased, the commodities are sequentially added in a code scanning manner, and meanwhile, a secondary screen of the cashier platform displays specific commodities and price information to a user; after all the commodities are scanned, a cashier clicks a money collection button, the main screen of the platform displays the total amount, the auxiliary screen displays the amount to be paid to a user, and meanwhile voice broadcasting is carried out; the consumer pays the cashier; the system confirms whether the payment is successful or not, the successful voice prompts 'payment is successful', and the failure prompts 'payment is failed and re-payment is requested'.

For example, when a consumer comes to a pay desk, the cashier first scans all the bar codes of the purchased commodities; the background of the payment desk immediately acquires the corresponding amount to be paid and informs the consumer of the amount to be paid by voice and sub-screen text information; the consumer pays the cashier; the cashier collects the money, verifies the cash and confirms whether the payment is successful or not; if change is required, confirming whether payment is successful or not after change is made; and after the cashier confirms that the payment is successful, the payment process is finished.

The payment process requires establishing communication between the primary screen cashier module and the secondary screen display module. And the main screen of the B/S (Browser/Server) end realizes the communication with the auxiliary screen through Socket. A browser kernel is built in a C/S (Client/Server) program, preferably, a Chrome browser kernel is built in and then is sleeved in a B/S program, and the B/S program is disguised as a program with a C/S function, namely, the browser is simulated as a Client of the C/S. The benefits of applying the above approach to traffic handling here are as follows: the main screen and the auxiliary screen are two browsers, communication between the two browsers needs to be carried out, the original communication mode is that communication is realized by utilizing localStorage, updating localStorage in one window and monitoring storage events of window objects in the other window. This communication requires that the two pages be homologous, i.e. the protocol, domain name and port of the URL are the same and cannot cross the browser. However, the method is simulated to be a C/S mode, the sockets are used for communication, the problems can be avoided, all the sockets monitor the same server address, send information by using the send, not only can windows, but also can cross browsers, the compatibility is good, and only point server resources need to be consumed. Meanwhile, in the C/S mode, the WinForm program component is used for realizing split screen display, and main screens and auxiliary screens can be cut at will, the number of split screens is increased, attributes are set, and the like.

The communication process of the first communication module of a particular home screen is as follows:

1. the method comprises the steps that a cashier desk main screen sends a message, wherein the main screen is a Client end of a C/S (Client/server) mentioned later, the Client loads a socket library and creates a socket (WSAStartup ()/socket); if the socket library loading is successful, returning to 'success of socket library initialization', and if the socket library loading is failed, prompting 'failure of socket initialization'; checking the socket library version number, if not, prompting that the socket library version number does not accord, and if the socket library version number is correct, prompting that the socket library version is correct.

2. The Client terminal sends a connection request (net ()) to the Server terminal; if the connection is successful, the server connection is successful, and the following information communication is continued, and if the connection is failed, the server connection is failed, and the connection needs to be reestablished.

3. Communicating (send ()/recv ()) with the server; the main screen sends a message, if the sending fails, the main screen prompts 'sending failure', and if the sending fails, the main screen sends the message to the server.

4. And after the information is sent, closing the socket and closing the loaded socket library.

The communication process of the second communication module of the specific secondary screen is similar to that of the first communication module, and is not described in detail.

The communication process of the C/S Server side (Server) is as follows:

5. while the Client terminal carries out the operation, the server terminal also needs to carry out a series of operations. The Server loads a socket library and creates a socket (WSAStartup ()/socket); if the socket library loading is successful, returning to 'success of socket library initialization', and if the socket library loading is failed, prompting 'failure of socket initialization'; checking the socket library version number, if not, prompting that the socket library version number does not accord, and if the socket library version number is correct, prompting that the socket library version is correct.

6. The Server side binds the socket to an IP address and a port (bind ()), and the IP address and the port number are bound here, so that the Client side can find the Server side to be accessed.

7. Setting a socket to a listening mode waiting for a connection request (listen ()); the successful setting of the monitoring state prompts 'the successful setting of the monitoring state', otherwise, prompts 'the failure of the setting of the monitoring state'.

8. After the Client end requests, the Server end receives the connection request and returns a new socket (accept ()) corresponding to the connection.

9. And communicating with the Client terminal by using the returned socket (send ()/recv ()).

10. And returning, and waiting for another connection request.

11. Close the socket, close the loaded socket library (closestoke ()/WSACLeanup ()).

For example, the main screen clicks the receipt confirmation button, and sends a receipt confirmation message to the C/S terminal, and simultaneously sends the current amount of consumption together. And the C/S converts the information into an xml file for storage, establishes communication between the Client terminal and the server terminal, replies XX.XX element of the current consumption to the Client terminal after the server terminal successfully receives the sent information, requests to show a payment code, and simultaneously sends the information to a secondary screen of a cashier desk for the consumer to check the payment information and prompt the consumer to pay, and simultaneously triggers a horn of a cashier system to prompt the cashier to prompt the user to request to scan the code. If the code scanning is successful, returning the code scanning success information to the auxiliary screen through the C/S terminal to display 'money deduction is successful', and displaying 'XX Xiaomaizhu welcome'; if the balance is insufficient, returning information of insufficient balance; the payment code cannot be identified, the two-dimensional code is illegal, and the like, and corresponding information of 'invalid two-dimensional code' and the like is prompted; if the network is overtime or the C/S terminal fails to receive any prompt information after code scanning in more than 3 minutes, the 'failure payment' information is automatically sent back to the auxiliary screen.

And after the consumer successfully finishes payment, all information of the consumer shopping is stored in the background database platform. The connection of the database is mainly carried out by utilizing a database interface through a database address, a port number and a user name password. Storing information to the database platform is for convenience the preferred solution mentioned below.

As a preferred scheme of the present invention, the sub-screen display module includes an electronic bill two-dimensional code display module, which is used for displaying the two-dimensional code of the obtained electronic bill to the user. The database platform is also provided with an electronic bill pushing interface, so that the shopping information of the consumer can be pushed to the consumer after the consumer completes payment. Specifically, the push interface may be a generated two-dimensional code identifier, and the consumer may scan the two-dimensional code, obtain the electronic bill information on the mobile phone, and optionally send the electronic bill to a WeChat or an electronic mailbox of the consumer, or the like. Through adopting the form of electron bill, for the bill of base paper matter, practiced thrift the resource, also make things convenient for the consumer to look over bill information, keep, receipt voucher and payment voucher at any time simultaneously.

It must be noted that in any of the above embodiments, the methods are not necessarily executed in order of sequence number, and as long as it cannot be assumed from the execution logic that they are necessarily executed in a certain order, it means that they can be executed in any other possible order.

It will be understood by those skilled in the art that the foregoing is merely a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included within the scope of the present invention.
