A further description of a bridge system based on a face brushing device in the present exemplary embodiment will be provided below.

In an embodiment of the present invention, the specific modes of the initialization configuration module include a self-service cash register mode and a non-self-service cash register mode; when the specific mode is the self-service cash register mode, the bridging system and the numeric keyboard perform transaction and communication, or when the specific mode is the non-self-service cash register mode, the bridging system and the third-party cash register device perform transaction and communication.

It should be noted that the bridging system of the present invention can divide the specific mode into a self-service cash register mode and a non-self-service cash register mode according to the diversification of the use modes and scenes and whether the system is used in combination with a cash register; the self-service cash register mode is that the bridge system is used independently and is matched with a digital keyboard to initiate transaction; in the self-service cash register mode, the bridge system cannot communicate with external equipment, can independently initiate a transaction request and can be regarded as an independent cash register system; the non-self-service cash register mode is that the bridging system is matched with a third-party cash register device, the bridging system is communicated with the third-party cash register device through the data communication transceiving module, and the third-party cash register device initiates a transaction; in the non-self-service cash register mode, after calling the face brushing application to complete the transaction, the bridging system needs to inform a third-party cash register device; meanwhile, the use of a numeric keyboard is forbidden under the non-self-service cash registering mode.

When the initialization configuration module is used for initialization configuration, the bridging system determines which specific mode is used so as to configure the parameter information in the specific mode; if the user uses the voice broadcasting module matched with the bridging system to realize the voice broadcasting function, the input overtime is started by the numeric keyboard in the self-service cash register mode, when the face-brushing application is called, whether the face-brushing application shows a transaction result when the transaction is finished, whether a transaction receipt is printed, parameter information setting under some special scenes and the like are carried out.

In addition, when the bridging system is in an idle state, the related configuration of the bridging system can be modified by entering a configuration page through the initialization configuration module, and the modified bridging system takes effect immediately without restarting the bridging system; when the bridging system is in an idle state, the bridging system can circularly play the merchant propaganda advertisement picture, and enters the idle state after the initialization of the merchant propaganda advertisement picture is completed.

As an example, after the initialization is completed, the bridging system of the present invention enters an idle state, and the idle state calls an advertisement module to perform carousel of advertisements; meanwhile, the thread maintained by the transaction processing pool module can also initiate transaction request processing when detecting that the transaction processing pool module has a request; in the idle state, a numeric keyboard or a user can manually click and call out a configuration page of the bridging system, and the related configuration of the bridging system is changed or switched; and after the relevant configuration is switched, the system can be effective without restarting the bridging system.

In an embodiment of the present invention, the data communication transceiver module includes a bluetooth communication unit and a serial communication unit; when the transaction initiating request is the third-party cash register of the Windows system, the data communication transceiver module is the serial port communication unit; and/or when the transaction initiating request is the third-party cash register equipment of the Android system, the data communication transceiver module is the Bluetooth communication unit; and/or when the transaction initiation request is a numeric keyboard, the data communication transceiver module is one of the serial port communication unit and the Bluetooth communication unit.

It should be noted that the transaction data refers to the transaction request and the transaction amount obtained by converting a preset format; when the transaction data of the numeric keyboard is received, the bridging system is required to perform format conversion on the transaction data according to a format conversion unit of the transaction processing pool module; when transaction data of third-party cash register equipment are received, the bridging system is required to perform format conversion on the transaction data according to a format conversion unit of the transaction processing pool module; when transaction data defined by a non-bridging system is received, if the third-party cashier equipment does not agree with the bridging system in a data format, processing illegal data; if the third-party cashier device and the bridging system agree on a data format, the bridging system acquires transaction elements required by the transaction processing pool according to the agreed data format, and the bridging system performs format conversion on transaction data according to a format conversion unit of a transaction processing pool module; meanwhile, whether the original data sent by the third-party cash register device is stored is determined according to needs.

It should be noted that, in the communication mode with the third-party cash register device, considering different operating systems possibly existing in the third-party cash register device, the bluetooth communication unit of the bridge system supports bluetooth communication and the serial communication unit supports serial communication:

as an example, when the bluetooth communication is implemented by the bluetooth communication unit, the bridging system uses itself as a bluetooth server, starts a thread to monitor the bluetooth state in real time by using a fixed UUID (universal Unique Identifier), and starts the thread to receive transaction data transmitted by bluetooth in real time when the bluetooth communication unit is connected by a third-party cashier device; after receiving the transaction data, firstly checking whether the transaction data is complete or not and whether the data format of the transaction data is correct or not according to the communication protocol, and directly returning a result to a third-party cashier device when the transaction data is wrong, so that the next state cannot be entered; in a specific embodiment, when the bridge system realizes bluetooth communication through the bluetooth communication unit, the device opens the bluetooth with a fixed UUID during initialization, and uses itself as a server to wait for connection of the third party cash register device; the Bluetooth connection adopts a long connection, and when the bridge system is abnormally disconnected for some reasons, the Bluetooth service can be automatically turned on again to wait for the reconnection of the cash register device.

As an example, when serial port communication is realized through a serial port communication unit, a bridging system opens a device node "/dev/ttyS 1" through an RS232 interface corresponding to a device, starts a thread to monitor the serial port in real time to receive transaction data, delays 50 milliseconds after the transaction data is received, and circularly receives the transaction data again, so that the transaction data is prevented from being received mistakenly due to too short time; after receiving the transaction data, checking the integrity of the transaction data and the format problem of the transaction data according to a communication protocol, assembling a new instruction according to the requirement to start the transaction and entering the next state after no error exists; in a specific embodiment, when the bridge system realizes serial communication through the serial communication unit, the device is connected with a third party cash register device through an RS232 interface, and performs data communication through a data protocol defined by the bridge system; the bridge system opens the RS232 node during initialization, sets node information such as baud rate, check type, data bit, stop bit and the like, then starts a receiving thread, and circularly reads transaction data of the node; for receiving the integrity of the transaction data, the loop is delayed by 50ms each time; in order to ensure the stability of transaction data transmission during serial port communication, a long connection mode is adopted, and when the bridge system is abnormally disconnected for some reasons, the bridge system automatically tries to open the nodes again and receives the nodes again.

It should be noted that, when communicating with the third-party cash register device of the Windows system, serial port communication may be adopted; when the system is communicated with the third-party cash register equipment of the Android system, Bluetooth communication can be adopted; meanwhile, communication data all need to meet a data protocol defined by a bridging system; the system can provide various modes to communicate with other third-party cash register equipment, and can be quickly accessed to the existing cash register system; the third-party cash register device may be, but is not limited to, cash registers of different operating systems such as a Windows system and an Android system.

It should be noted that the data communication transceiver module also receives transaction data from the numeric keypad, and mainly includes transaction data such as a transaction request and an opening setting request.

It should be noted that the data communication transceiver module is also responsible for analyzing and recombining the received transaction data; the communication protocol of the third-party cashier device and the bridging system generally uses a data protocol defined by the bridging system, and if the third-party cashier device has a data format, the bridging system can be quickly reconstructed according to the data format; the data format generally adopts a JSON (JavaScript Object Notation) format; after receiving transaction data, extracting key elements for recombination according to a request data format required by face brushing application, and adding the key elements to a transaction processing pool module after the recombination is completed; after the transaction is completed, when transaction result data is received, key elements are extracted according to a used protocol to be recombined, and a result is returned to the third-party cash register device; of course, a transaction request initiated with a numeric keypad does not require a return result.

In an embodiment of the invention, the face-brushing application includes a union pay face-brushing application and a WeChat payment application.

It should be noted that the face brushing application supported by the invention can be unionpay face brushing payment and can also support WeChat face brushing payment in a compatible manner. The call of the unionpay face-brushing payment is an AIDL (Android Interface Definition Language) file provided by the unionpay face-brushing payment, and the WeChat face-brushing payment is an AAR (Android Archive, binary Archive file of Android library item) file for calling a WeChat SDK (Software Development Kit) provided by WeChat, which is still Android cross-process communication essentially.

In an embodiment of the present invention, the transaction processing pool module includes a format conversion unit and a status monitoring unit; the format conversion unit is used for storing the transaction data in a transaction processing pool according to a preset format; the state monitoring unit is used for monitoring the transaction state of the transaction data, wherein the transaction state comprises an unscranslated state and a transacting state.

It should be noted that the transaction processing pool module maintains a single thread and a transaction state, the single thread is used for controlling the transaction sequence, and the transaction entering the transaction processing pool module first is preferentially carried out according to the first-in first-out principle; the transaction state has two states, namely an unsransaction state and a transaction state, which respectively represent whether a transaction is carried out or not; the transaction data entering the transaction processing pool module needs to be subjected to format unification through a format conversion unit; when the transaction processing pool module has no transaction data, the bridging system enters an idle state; when the transaction processing pool module has transaction data, the bridging system can determine to start transaction or wait for the completion of the previous transaction according to the transaction state; when no transaction is currently carried out, namely the transaction state is an unscheduled state, taking out the transaction which is entered preferentially from the transaction processing pool module, starting to initiate the transaction, and simultaneously setting the transaction state as a transaction state; and when the transaction is completed, modifying the transaction state into an unsransactionated state, and returning to the transaction processing pool module to check whether transaction data exists or not.

As an example, when the transaction state is an unsransactionated state, the transaction data in the transaction processing pool module is acquired to perform a transaction; and when the transaction state is the transaction-in state, waiting for the transaction processing to be finished.

As an example, after receiving a transaction request, the data communication transceiver module of the bridging system of the present invention will add the request to the transaction processing pool module, and a thread maintained by the transaction processing pool module circularly processes all transactions, with the processing principle being first-in first-out; meanwhile, the transaction processing pool module also maintains a variable of a transaction state, the transaction state is a transaction-in state when the bridging system processes a transaction request, and the transaction state is an non-transaction state when the bridging system processes a transaction request; when the thread of the transaction processing pool module acquires that the transaction state is the non-transaction state, acquiring a next transaction request from the transaction processing pool module, putting the transaction request into the next step for transaction processing, changing the transaction state into the transaction state, waiting for the completion of the transaction processing, and sequentially circulating. Transaction processing is performed in a separate thread that invokes the cross-process communication module to process the transaction, while also changing the UI display of the bridge system itself.

It should be noted that, the main transaction elements carried by one transaction request include: and identifying the unique transaction order number and transaction amount of the transaction, controlling whether the face brushing application displays the control parameters of the transaction result or not when the transaction is completed, and controlling whether the printing parameters of the receipt are printed or not after the transaction is completed.

It should be noted that, the transaction processing pool module can set the maximum transaction request number and also includes an exception handling mechanism; the transaction processing pool module can sequentially process a plurality of transaction requests when receiving the transaction requests at the same time, and the problems of transaction flow confusion and the like can be avoided.

In an embodiment of the present invention, the cross-process communication module refers to aid communication in Android.

It should be noted that the cross-process communication module is responsible for communication between the bridge system and the face brushing application, and aid communication in an Android cross-process communication mechanism is mainly adopted. The bridging system and the face brushing application have a common AIDL file, the bridging system binds the Service of the face brushing application (the Service is one of four major components in the Android system, has a long life cycle, has no visual interface and runs in a background Service program) according to the ACTION (the ACTION class is a bridge between a user request and Service logic, and each ACTION serves as a Service agent of a client) provided by the face brushing application, acquires a corresponding interface instance, and calls the corresponding interface of the face brushing application through the instance to initiate a transaction. And when the transaction is completed, the face brushing application can call back the AIDL interface in the bridging system, so that the corresponding transaction result is obtained through the bridging system.

As an example, after receiving a callback result of the face-brushing application, the cross-process communication module transmits data to the transaction data processing module, and the transaction data processing module analyzes the transaction result, acquires key elements of the transaction, reassembles the data, controls and displays the transaction elements, and the like.

In an embodiment of the present invention, the transaction data processing module includes a transaction result analyzing unit, a packaging display data unit and a packaging return data unit; the transaction result analysis unit is used for analyzing according to the callback result to obtain a transaction result; the packaging display data unit is used for performing visual data processing and packaging processing according to the transaction result; and the packaging return data unit is used for adjusting the data suitable for the third-party cash register device according to the transaction result and packaging the data suitable for the third-party cash register device.

It should be noted that the transaction data processing module refers to callback result processing of the face brushing application received by the cross-process communication module; the bridging system can communicate with the face brushing application through the cross-process communication module, call back the bridging system after the face brushing application processes the transaction, process the transaction result through the transaction result analysis unit, return the transaction result to the third-party cash register device through the packaging return data unit, and display the transaction result through the packaging display data unit.

As an example, in a transaction processing process, firstly, a face-brushing application is called to start a transaction through an Android cross-process communication mechanism aid l of a cross-process communication module; when the transaction processing of the face brushing application is finished, the user can call back to the bridging system; after receiving the callback data, the bridging system judges whether the transaction is successful according to the difference of callback interfaces, meanwhile, the transaction key data in the callback result are taken, on one hand, the transaction result is packaged and displayed through the packaging display data unit, and on the other hand, the transaction result is packaged and displayed through the packaging return data unit according to the protocol, and the packaged data is returned to the third-party cash register device.

Specifically, after a transaction result of the cross-process communication module is received, the transaction result needs to be determined firstly, when the transaction is successful, transaction elements such as transaction amount and transaction time are obtained, data required by a transaction result display page is packaged through a packaging display data unit and transmitted to the transaction result display page for informing a user of the transaction condition; meanwhile, a data format required by the third-party cash register equipment is packaged through a packaging return data unit and used for informing the cash register equipment of the transaction result condition; similarly, when the transaction fails, the transaction failure description needs to be acquired, displayed to the user, and simultaneously notified to the cash register device; and according to the configuration of the bridging system, whether to broadcast the corresponding transaction result by voice is determined.

In an embodiment of the present invention, the transaction result display module is configured to display the corresponding transaction result and the key data corresponding to the transaction result according to the processing result.

It should be noted that the transaction result display module is used for displaying the transaction result and the key data of the transaction, and the key data at least includes transaction time, transaction amount and the like.
