Examples
The aim of the embodiment is to realize the many-to-many matching of the payment terminal subsystem and the cash register subsystem, which can allow a user to flexibly carry out. In the conventional WiFi technology, matching between a plurality of payment terminal subsystems and a plurality of cash register subsystems can be achieved by respectively setting static IP for the payment terminal subsystems and the cash register subsystems. However, the device is easy to preempt the set IP address by other devices accessing WiFi in a static IP mode, so that matching errors need to be corrected in time, and the device is inconvenient to use. In order to solve the problem, the invention adopts the following technical scheme:
as shown in fig. 1, the present invention provides an intelligent financial collection system, comprising: a payment terminal subsystem, a cash register subsystem and a data socket core dispatch management subsystem. For ease of understanding and distinguishing the two mating ends of the wireless connection, we refer to the receptacle and plug, respectively.

And receiving the payment service processing module, and sending the returned processing result to a data socket core dispatching management system.
Cash register subsystem
(1) Cash register business processing module
The cashless business is to call the socket passing module to complete the payment business such as bank card, payment treasures, weChat and the like, and then report the successful information to the background purchase, sale and storage system.
The cash register service processing module directly performs data interaction with the socket communication module and transmits: commodity deduction request data such as cash register identity information, order number, transaction amount and the like are received by the socket communication module: treatment results: success or failure, and corresponding auxiliary information, proportion: order number, amount of deduction completed, payment means (bank card, weChat, payment treasury, etc.), POS merchant number, POS terminal number, card number after desensitization of bank card, issuer name, acquirer name, payment serial number, etc.
(2) Socket management module
The system is used for managing and checking the identity information, service requirements, payment terminal types and the like of the socket, and provides an interface for inputting, maintaining and managing or other parameter input updating modes.
Identity information: cash register number, outlet serial number, logical number, network access token, data outlet core system network address, etc. Each socket has its own unique serial number, but is inconvenient to memorize and communicate by personnel. Each receptacle may be renamed a management number or name, such as a machine number, floor number + serial number.
Service requirements: such as to share 1:1 alone, or can share 1: n.
Payment terminal type: and controlling which payment terminals are distinguished by grouping and classifying, or designating a certain payment terminal with a number.
Network communication capability: support the communication protocol type, whether data receiving monitoring is possible, etc.
Payment matching query: information of the already matched payment terminal plug can be seen.
Initializing a socket: by calling the socket communication module, the socket identity information, the service requirement, the payment terminal type and the like are registered to the data socket core dispatching management system. The data socket core will return a responsive message: successful registration gives corresponding control parameters such as communication timeout time.
(3) Socket communication module
And receiving the call of the cash register service processing module and the socket management module, sending data to a data socket core dispatching management system, and returning the data to the call module after receiving and returning the data.
Data socket core scheduling management subsystem
And carrying out information management and security validity check on the terminal of the access system, setting a terminal matching strategy, and completing connection matching of the terminal according to the strategy to realize quick and effective transmission of data among the terminals in real time.
(1) Terminal management module
The information of each payment terminal and each cash register is registered, each terminal must firstly open an account in the system, the information of opening an account comprises information such as numbers, tokens, urban areas and the like, when the terminal is initialized, the transmitted registered information must be checked with the information of opening an account, the check is successful, the income submitted supplementary information is allowed, and the state of the juxtaposed terminal is effective.
In the terminal management module, certain information fields of the terminal can be forced, the effectiveness is higher than that of the self-setting parameter information sent by the terminal, and the information can be forced to be sent down to cover the parameter setting of the terminal.
(2) Terminal matching policy management module
And setting a matching strategy between the cash register and the payment terminal. For example, on a cash line of a large store, a payment terminal and a cash register machine number can be set to be consistent and matched. In the advanced hotel, the cash register and the payment terminal are matched in a consistent floor, the consumption information of a certain layer can be timely pushed to the free payment terminal of the current layer, and service personnel can carry the corresponding payment terminal to find out the consumer to carry out payment operation.
According to the embodiment, the terminal information in the plug management module and the socket management module is registered and matched in the data socket core dispatching management subsystem, so that the matching of the setting rule can be accurately realized even if the IP addresses of the payment terminal subsystem and the cash register subsystem after the internet connection are different every time, adjustment is not needed, and the method is very convenient.
If one cash register subsystem matches multiple payment terminal subsystems, then if there is no explicitly specified payment terminal subsystem, then a further decision is needed as to how to choose the payment terminal subsystem to complete the payment, so the data socket core schedule management subsystem further adds:
(3) Terminal state monitoring module
And updating the state of the terminal in the database in time according to the information sent by the payment terminal and the cash register terminal. Such as states include: available, in use, busy (queued), etc.
Therefore, the data socket core dispatching management subsystem can select according to the states of the payment terminal and the cash register terminal, so that the collection efficiency is improved.
According to the above scheme, the data socket core scheduling management subsystem can select the terminal to collect money according to the actual situation, at this time, if the selected terminal is busy, the newly transmitted collection task is easy to collide with the task in progress or the newly transmitted task is lost, so that the function of the task queue is further increased, specifically including that the data socket core scheduling management subsystem is further increased:
(4) Core data exchange module
And receiving initialization information of the terminal:
financial payment transactions are typically characterized by a communication back and forth, which we call requests and responses.
The data exchange module receives initialization information sent by the cash register and the payment terminal, completes matching of the socket and the plug according to a terminal matching strategy, and timely updates a terminal matching information table.
And receiving payment information of the cash register:
and after finding the matched available payment terminal, marking a time tag and matching the terminal information, putting the information into a data queue, informing the matched payment terminal that the information needs to be received according to the network communication capacity of the payment terminal in one mode, and directly sending the data to the payment terminal in the other mode.
And each time the information submitted by the payment terminal is received, the original request information is found out from the message queue, the corresponding relation of the necessary data fields is checked, and the response time and the like are checked and then sent to the cash register.
If the terminal cannot send, returning to the fact that the cash register payment terminal does not exist according to the matched payment terminal state, and the terminal is not started or is busy.
And for the situation that N can be matched, the core data exchange module sends the data to a specific payment terminal according to the transaction characteristic requirement in the cash register. For example, when the user needs to brush the face, only the payment terminal with the face brushing function can be used.
(5) Core data queue module
And checking the data in the queue at regular time, timely picking out the data invalid in time, and maintaining and refreshing the corresponding terminal state according to the processing result of the queue data.
The task ordering of the payment terminal and the cash register terminal can be realized through the embodiment, so that the mutual conflict between tasks is avoided. On the basis, the priority of each task can be further set, so that the aim of priority processing of important tasks is fulfilled.
In the invention, the collection tasks are all sent to the data socket core dispatching management subsystem by the plug communication module, and then the payment terminal subsystem actively inquires the data socket core dispatching management subsystem for processing the tasks corresponding to the collection tasks. The payment terminal subsystem is isolated from initiating the collection task, so that the condition that the illegal payment terminal subsystem accesses the system to impersonate a merchant for charging can be avoided.
The invention also provides an intelligent financial collection method, which comprises the following steps: the intelligent financial collection system is constructed, a matching strategy is set in the data socket core dispatching management subsystem, the payment terminal subsystem and the cash register subsystem are powered on and initialized, and the cash register and the payment terminal are matched into 1-to-1, 1-to-many, many-to-1 or many-to-many through the matching strategy.
