Description

Multifunctional consumption machine

Technical Field

The invention relates to the technical field of consumption machines, in particular to a multifunctional consumption machine.

Background

At present, because the existing consumer computer is not provided with corresponding authority management, sensitive setting items (such as parameters of network port and serial port communication, machine time, factory setting recovery, language setting and the like) in a menu interface or a function setting interface are likely to be changed randomly in the using process, and then the results of data confusion, communication failure, change of transaction flow and the like in the consumer computer are caused; meanwhile, when the consumption machine is in transaction, after the consumption machine processes the transaction data, the consumption machine rewrites the updated data into the card. Therefore, if the consumer cannot continue to work (power off, crash) or the card is suddenly removed due to a special reason during the writing process, the data in the card may not be completely updated successfully. At this time, the data in the card is incomplete, and if there is no processing mechanism, the wrong data will be used all the time in the later use of the card, which causes data confusion and problems in the transaction bill. Meanwhile, the existing consumption machine does not have the function of unlocking/locking the card, and can not process abnormal consumption data, so that even if abnormal consumption records exist, such as the abnormal consumption records of successful payment and the like, the IC card can be continuously used for transaction, and economic loss is brought to a consumer machine holder; moreover, at present, when the consumer machine uploads data, the uploaded data can not be uploaded next time after the uploading is finished. Therefore, when data is uploaded, uploading fails due to self problems or external reasons, and data loss occurs if the data is not processed; that is, when the consumer computer communicates with the upper computer software, the communication is easily interrupted due to a problem (such as the consumer computer going down) or an external problem (such as power failure and network interruption), thereby causing a problem of data loss.

Specifically, in this embodiment, the operation permission of the consumer computer needs to design the use permission of the consumer computer corresponding to different users through upper computer software, and transmit the use permission to the permission management module of the consumer computer through a communication mode of a network port or a serial port.

Firstly, information of operators is added through upper computer software, numbers are mainly set for different operators, corresponding roles are granted to the operators, and each role is set with corresponding authority. In the embodiment, the set authority comprises an interface login authority and an interface data modification authority; the interface login authority comprises a consumer machine menu interface login authority and a consumer machine function setting interface login authority, and the interface data modification authority comprises a consumer machine menu interface data modification authority and a consumer machine function setting interface data modification authority. The type of the role is determined, the authority range of each role is also determined, generally, the roles are divided into a security manager, a system engineer, a configuration engineer, a super operator, a common operator and the like, the authority range of the role of the security manager is the related authority of creating the role of a user, the corresponding authority of the role and the like, the authority range of the configuration engineer is the related authority of the configuration project, and the authority ranges of the super operator and the common operator are the authorities of operation control and the like. The user's scope of authority is related to his role. And if the user is a common operator, setting the authority of the user in the authority range corresponding to the common operator. And then storing the set user number, role and corresponding authority into an authority database unit. Specifically, the authority settings for the operator may be as shown in table 1:

table 1 permission setting situation table

As shown in table 1, the super operator may have both an interface login authority and an interface data modification authority, that is, may log in the menu interface and modify data in the menu interface, or may log in the function setting interface and modify data in the function setting interface, such as user 0001 and user 0002; however, some of the ordinary operators only have interface login permission, that is, only can log in a menu interface or a function setting interface to check corresponding settings, but cannot make modifications or changes, such as the user 1002; some devices have login authority of a menu interface and a function setting interface, but only have data modification authority of the function setting interface, but do not have data modification authority of the menu interface, that is, only data in the function setting interface can be modified or changed, and data in the menu interface cannot be modified or changed, for example, a user 1001.

Further, as an optional specific implementation manner, each role in the permission database unit corresponds to one sub-library, as shown in table 2, after permission of a user corresponding to a role is determined, a permission table corresponding to the user name (which may be the same name) is created in the sub-library corresponding to the role, and specific permission information of the user in the role is stored in the permission table.

TABLE 2

As shown in table 3:

TABLE 3

Operation ID	Device ID	Operation authority ID
			2541	7859	255
1479	7125	255

Specifically, the operation flow when the setting item of the consumer machine is to be modified is shown in fig. 3, and the consumer machine authority management module can set the consumer machine to be in two modes of requiring startup login and not requiring startup login; when the consumer computer is in a starting-up login mode, jumping to a user login interface after the consumer computer is started up so that an operator can input a number (or an account number) and a password to log in; when the mode does not need the startup login mode, the main interface is directly displayed after the consumption machine is started. In the startup login mode, a user jumps to a main interface after login is successful, and the main interface displays a menu key, a function key and a return key; when a user presses a 'menu' key or a 'function' key, the system can judge whether the user logs in at present, at the moment, if the user does not need a startup login mode, the system can judge that the user does not log in at present, and jump to a user login interface for an operator to input a number (or an account) and a password for login, and after the user logs in successfully, user information is obtained; if the user needs to be logged in, the system can judge that the user logs in currently, and then the user information is directly acquired. According to the acquired user information, calling data stored in a permission database, and according to the information stored in the permission database unit, performing permission authentication on the user; and displaying a corresponding setting interface according to the authentication result, wherein the setting interface comprises a menu setting interface and a function setting interface. Specifically, the right management method of the consumption machine comprises the following steps:

s1, obtaining user information, wherein the user information comprises a user login account and a password;

s2, calling information stored in the permission database unit;

s3, performing authority authentication on the user according to the information stored in the authority database unit;

and S4, displaying a corresponding consumer machine setting interface according to the authentication result, wherein the consumer machine setting interface comprises a menu setting interface and a function setting interface.

Specifically, the step S2, that is, the step of retrieving the information stored in the permission database unit, includes:

s201, detecting whether a display interface of a consumption machine jumps to a setting interface of the consumption machine;

s201-1, when detecting that the display interface of the consumer computer jumps to the setting interface of the consumer computer, calling the information stored in the permission database unit;

s201-2, when the display interface of the consumer computer is detected not to jump to the setting interface of the consumer computer, the authority of the user is not authenticated.

In this embodiment, when it is detected that the "menu" key or the "function" key is clicked, it indicates that the display interface of the consumer computer is to jump to the setting interface, that is, to jump to the menu interface or the function setting interface; and if the 'menu' key or the 'function' key is not detected to be clicked, the fact that the corresponding interface login authority authentication of the user is not needed is shown.

The step S3, that is, the step of performing the authority authentication on the user according to the information stored in the authority database unit, specifically includes:

s301, identifying user information, wherein the user information comprises a user login account and a password;

s302, searching the user information and the authority information corresponding to the user in an authority database unit;

and S303, authenticating the user according to the user information and the authority information corresponding to the user.

In this embodiment, the permission setting table or the role permission table stored in the permission database unit may be adjusted and taken out, and whether the user has a corresponding operation permission is searched. Specifically, whether the information of the user is stored in the permission database unit is searched, and if not, the user is judged not to have the login interface permission and the interface data modification permission. And if the information of the user is stored in the authority database unit, calling the role corresponding to the user and the authority information of the user, authenticating the user according to the authority information, jumping to a corresponding interface for the user to operate after the authentication is passed, and jumping out a prompt interface of login failure or popping up a prompt window without setting authority when the authentication is failed. For example, the authority management module detects that a "menu" key is clicked, at this time, identifies information of a login user, obtains an account number 1001 of the login user, calls out an authority setting table or a role authority table stored in an authority database unit, and searches whether the user 1001 has a corresponding operation authority, that is, whether the user has an authority to login a menu interface, if so, jumps to the menu interface, and if not, jumps to a prompt interface with login failure. Assuming that the user 1001 has the authority to log in the menu interface, the user 1001 successfully logs in the menu interface, at this time, if it is detected that the user 1001 needs to modify data in the menu interface, such as resetting parameters of internet access and serial port communication, the role corresponding to the user and the authority information are further called, and the user is authenticated according to the authority information, at this time, if the user 1001 has the authority to modify the menu interface data, the parameters of internet access and serial port communication can be reset, and if the user 1001 does not have the authority to modify the menu interface data, a reminding window without the authority is popped up.

In summary, the rights management module of the consumer machine in this embodiment has the following advantages:

the embodiment of the invention can use the consumption machine with permission by arranging the permission management module, can appoint part of professionals or operators to correspondingly modify some functions of the consumption machine, can effectively avoid the problems of data confusion, communication failure, change of transaction flow and the like caused by random operation of other people on the consumption machine, can also prevent non-working personnel from illegally and maliciously using the consumption machine, and avoids economic loss.

Further, as an optional implementation manner, the exception data processing unit includes:

the reading subunit is used for reading the transaction data of the card;

The abnormal data processing unit also comprises a storage subunit;

the storage subunit is used for storing all transaction data of the card.

The reading subunit includes:

First, a specific process of processing each transaction data by the consumer machine needs to be described, as shown in fig. 4, when the consumer machine performs a certain transaction, for example, when a payment amount of a certain consumption is received, the CPU module of the consumer machine sends a command for writing the card locking mark to the RF card reader module, and after receiving the command for writing the card locking mark, the RF card reader module returns a response to indicate whether the card locking mark is successfully written into the card. If the RF card reader module returns a response of write failure and needs to swipe the card again, at this time, if the user exits the transaction state, for example, the user does not swipe the card for the second time, or the operator presses a cancel key and exits the current transaction interface, the consumption machine stores the transaction data of the time into the external storage module, attaches a card locking mark to the transaction data of the time, and marks the transaction data as abnormal data; at this time, since the card does not normally complete payment, the card enters a card locking state, and the card can be reused only by unlocking the card. And if the RF card reader module returns a response of successful writing, the consumer machine writes the card locking mark into the card and continues to write the transaction data of the time into the card for payment through the RF card reader module, and the specific process is as follows: the CPU module of the consumption machine sends a command for writing the transaction data to the RF card reader module, and the RF card reader module returns a response after receiving the command for writing the transaction data so as to indicate whether the transaction data is successfully written into the card; if the RF card reader module returns a response of write failure, the card needs to be swiped again, at this time, if the user exits the transaction state, for example, the user does not swipe the card for the second time, or the operator presses a cancel key, and exits the interface of the current transaction, the consumption machine stores the transaction data of the current time into the external storage module, and similarly, the card locking mark is attached to the transaction data of the current time and is marked as abnormal data; if the RF card reader module returns a response of writing success, the consumer writes the transaction data of the time into the card and simultaneously clears the previously written card locking mark, wherein the specific operation of clearing the previously written card locking mark is as follows: the CPU module of the consumer computer sends a write command to the RF card reader module, and writes a value different from the card locking mark into the card to cover the previously written card locking mark, and the RF card reader module returns a response after receiving the command to indicate whether the previously written card locking mark is successfully cleared; if the RF card reader module returns a response of write failure, the card needs to be swiped again, at this time, if the user exits the transaction state, for example, the user does not swipe the card for the second time, or the operator presses a cancel key, and exits the interface of the current transaction, the consumption machine stores the transaction data of the current time into the external storage module, and similarly, the card locking mark is attached to the transaction data of the current time and is marked as abnormal data; and if the RF card reader module returns a response of successful writing, the consumption module stores the transaction data of the time into an external storage module and exits the transaction state.

As can be seen from fig. 4, if no transaction is successful and a card is swiped for the second time, the user exits the transaction state, or the operator presses the cancel key and exits the interface of the current transaction, the consumer will store the transaction data of this time in the external storage module, attach the card locking mark to the transaction data of this time, and mark the transaction data as abnormal data, and at this time, because the card does not normally complete payment, the card enters the card locking state, and the card needs to be unlocked and can be reused.

In the embodiment, when the consumer machine transacts through the card, the consumer machine firstly reads the data in the card, then judges whether the read data in the card has the card locking mark, if not, the consumer machine continues the normal transaction flow, if so, the consumer machine prompts the card to be locked and displays the card on the display screen; at this time, the card needs to be unlocked to be reused. The embodiment processes abnormal data together through the upper computer and the consumption machine, and specifically comprises the following steps:

(1) the upper computer recovers transaction data in the consumption machine and displays the transaction data in upper computer software, wherein the transaction data comprises abnormal consumption data, namely abnormal data;

(2) the upper computer software reads the transaction data in the card through the RF card reader module of the consumption machine, and specifically comprises the following steps: sending a command for reading transaction data to an RF card reader module, wherein the RF card reader module receives the command and returns the transaction data in the card;

(3) the upper computer stores the read transaction data in the card in software;

(4) the upper computer software searches all transaction data related to the card in the received transaction data in the consumer computer, and extracts abnormal data from all transaction data;

(5) the upper computer software clears the card locking mark in the stored card data;

(6) the upper computer software searches the latest normal transaction data of the card in the received transaction data in the consumer computer;

(7) the upper computer software replaces the stored card data with the latest normal transaction data;

(8) writing the replaced data into the card, specifically: the method comprises the steps that a command for writing data is sent to an RF card reader module, and after the RF card reader module receives the command, the replaced data is written into a card so as to cover original abnormal data of the card;

and deleting the abnormal data processed in the consumption machine.

Referring to fig. 5, another processing mechanism for processing abnormal data of a consumer machine includes the following processing flows:

the consumption machine reads the data in the card and judges whether the card is locked or not, if so, the consumption machine prompts that the card is in a card locking state, enters an unlocking processing mode, clears a card locking mark in the card data, and simultaneously finds a piece of continuous normal transaction data on the card in the consumption machine, thereby restoring the card data to a state of finishing the operation of the previous piece of normal transaction data; if the card is not locked, further judging whether the transaction data is data of wrong transaction amount, if so, converting the data into effective data and inserting the effective data into the transaction data, and returning more or less than the transaction amount in the wrong transaction amount data; if the transaction amount is not the data of the error transaction amount, the transaction data is judged to be normal transaction data, and the processing is not carried out. In this embodiment, a processing method for abnormal data when a transaction is completed in error is provided, for example, the deduct amount is incorrect, and at this time, although the transaction is completed normally, the transaction amount is incorrect, that is, part of data in the transaction data is incorrect, and the data also belongs to the abnormal data. The transaction is normally completed, so the card can not be locked by the consumption machine, at the moment, the specific transaction data with wrong deduction can be directly found out and changed to become valid data and stored as the data of the transaction, and meanwhile, the more-collected amount or the less-collected amount in the wrong transaction amount data can be returned.

In summary, the exception data processing unit of the consumer machine in this embodiment has the following advantages:

Each packet data consists of a packet header, data, a CRC check word and a packet tail. The head and tail of the packet are a fixed segment of data; the CRC check word is used to check the packet data. Similarly, the terminal transmits the data to the application layer after the data is successfully received by the transmission layer. The application layer firstly unpacks the received data, judges whether the head and the tail of the packet are correct, judges whether the CRC check is correct and judges whether the format of the data is correct. If the application layer of the terminal unpacks the packet, the packet header, the packet tail, the CRC check and any field data in the data are incorrect, the data are judged to be unpacked failure, namely data transmission error; similarly, when the consumer receives the response signal data returned by the terminal, the application layer of the consumer first unpacks the received response signal data, determines whether the header and the trailer are correct, determines whether the CRC check is correct, and determines whether the format of the data is correct. If the application layer of the consumer machine unpacks the packet, the packet header, the packet tail, the CRC check, and any field data in the data are incorrect, the unpacking is judged to be a failure, that is, a data transmission error.

In this embodiment, without considering the case of data transmission error, it is assumed that the consumer computer can unpack successfully when receiving the response signal data returned by the terminal and the terminal receives the data to be sent by the consumer computer, that is, the packet header, the packet trailer, the CRC check, and any field data in the data are correct, and the flow of the data processing method is specifically as follows:

1. the consumption machine starts to send data to be sent, and after the application layer of the consumption machine sends a packet of data, the consumption machine enters a receiving state and waits for the terminal to return a response signal data packet. And starts a countdown waiting for reception.

(1) If the consumer machine is sending a packet of data, it has not yet been completely transmitted to the terminal, but the transmission medium is suddenly disconnected. At this time, the transmission layer of the terminal stops receiving due to the fact that data cannot be received;

(2) the application layer of the terminal does not return a response signal data packet to the consumer because the application layer does not receive any data sent by the transmission layer;

(3) the transmission layer of the consumer does not receive any data, and the application layer waits for a period of time before the countdown time is over. The application layer judges that the communication is overtime because no data is received, and then the communication is ended;

(4) at this point there is no loss or duplication of data.

2. After the transmission layer of the terminal successfully receives the data sent by the consumer, the data are transmitted to the application layer, the application layer can store the data, at the moment, the application layer of the terminal can send a response signal data packet to the consumer through the transmission layer, then the application layer enters a receiving state, waits for receiving the next packet of data, and starts a countdown waiting for receiving.

(1) If the terminal sends a response signal data packet to the consumer, the transmission medium is suddenly disconnected, the transmission layer of the consumer stops receiving due to no data being received, and the application layer does not receive any data sent by the transmission layer;

(2) after waiting for a period of time, the application layer of the consumer computer judges that the communication is overtime because no response is received, and then the communication is ended;

(3) similarly, the transmission layer of the terminal does not receive the next packet of data sent by the consumer, and after the countdown of the application layer is finished, the communication is judged to be overtime because no data is received, and then the communication is finished;

(4) at this time, the data in the packet exists in the consumer computer and the upper computer at the same time, and repeated data segments appear.

3. After receiving the response signal data packet, the transmission layer of the consumer machine transmits the response signal data packet to the application layer. The application layer cancels the countdown when receiving the response signal packet.

(1) If the consumption machine is down after the transmission layer of the consumption machine receives a packet of response signal data packet or during the receiving process, the consumption machine loses the communication capability, and the communication is directly finished;

(2) the terminal judges that the communication is overtime because no data is received after the countdown of the application layer of the terminal is finished because the transmission layer does not receive the next packet of data sent by the consumer, and then the communication is finished;

(3) at this time, the packet data exists in the consumer computer and the upper computer at the same time, and repeated data segments appear.

4. And after receiving the response signal data packet, the application layer of the consumer machine judges that the terminal has successfully received the last packet of data. Thus, the consuming machine deletes the last packet of data sent from the consuming machine.

(1) If the consumer machine is down after deleting the previous packet of data, the consumer machine directly finishes the communication;

(3) at this point there is no loss or duplication of data.

5. And the application layer of the consumer computer can judge whether data which needs to be sent still exist after receiving the response signal data packet, and if the data which needs to be sent do not exist, the application layer of the consumer computer can send an empty data packet and transmit the empty data packet to the terminal through the transmission layer.

6. And after receiving the empty data packet, the transmission layer of the terminal transmits the empty data packet to the application layer. And the application layer cancels the countdown when receiving the empty data packet, and simultaneously, the application layer of the terminal judges that the data is completely received after receiving the empty data packet, sends a response signal data packet and sends the response signal data packet to the consumer machine through the transmission layer. The application layer then ends the communication.

7. The transmission layer of the consumer machine receives the response signal data packet of the null data packet and then transmits the response signal data packet to the application layer. And when the application layer receives the response signal data packet of the null data packet, the countdown is cancelled, and the communication is ended.

In this embodiment, if a data transmission error is considered, it is assumed that when the consumer receives the response signal data returned by the terminal and the terminal receives the data to be transmitted sent from the consumer, an unpacking failure may occur, that is, a packet header, a packet trailer, a CRC check, and any field data in the data are incorrect in the data packet, and both the unpacking failure and the data transmission error are determined. At this time, the data processing method flow refers to fig. 6, fig. 6 is one of the processing flows of the data processing method according to an embodiment of the present invention, and the flow specifically includes:

1. the consumer machine starts to send data, and after the application layer of the consumer machine sends a packet of data, the consumer machine enters a receiving state, waits for a response packet to be returned, and starts a countdown waiting for receiving.

(1) If the consumer machine is sending this packet of data, it has not yet been completely transmitted to the terminal, but the transmission medium is suddenly disconnected. At this time, the transmission layer of the terminal stops receiving due to the fact that data cannot be received;

(4) at this point there is no loss or duplication of data.

2. After the transmission layer of the terminal successfully receives the packet data, the packet data is transmitted to the application layer, and the application layer firstly carries out unpacking processing on the received packet data, judges whether the packet head and the packet tail are correct, judges whether CRC (cyclic redundancy check) is correct and judges whether the format of the data is correct.

(1) If the application layer of the terminal unpacks the packet, the packet header, the packet tail, the CRC check and any field data in the data are incorrect, the data are judged to be unpacked failure, namely data transmission error; at this time, the application layer of the terminal discards the received data, and then, the application layer of the terminal sends an analysis failure response packet to the consumer machine through the transport layer. The application layer enters a receiving state, waits for receiving the packet data again, and starts a countdown waiting for receiving;

(2) and after receiving the response packet of the analysis failure, the transmission layer of the consumer machine transmits the response packet to the application layer. And after receiving the analysis failure response packet, the application layer cancels the receiving countdown and then analyzes the analysis failure response packet. After successful analysis, whether three times of failed analysis response packets are received or not is judged, and if not, the data of the packets are retransmitted. If the application layer of the consumer machine recognizes that the analysis failure response packet is received for three times continuously, the transmission failure is judged, and then the communication is ended;

(3) the application layer of the terminal judges that the receiving is overtime because the receiving countdown is finished and no receiving exists, and then the communication is finished;

(4) at this point there is no loss or duplication of data.

3. After the application layer of the terminal is unpacked successfully, data can be extracted and stored in a database, and then the application layer of the terminal can send a response signal data packet to the consumer through the transmission layer; the application layer of the terminal enters a receiving state, waits for receiving the next packet of data, and starts a countdown waiting for receiving.

(1) If the terminal returns a response signal packet to the consumer, the transmission medium is suddenly disconnected. The transmission layer of the consumer computer stops receiving due to the fact that the data cannot be received, and the application layer of the consumer computer does not receive any data sent by the transmission layer;

(4) at this time, the packet data exists in the consumer computer and the upper computer at the same time, and repeated data segments appear.

4. After receiving the response signal data packet, the transmission layer of the consumer machine transmits the response signal data packet to the application layer. The application layer cancels the countdown when receiving the response signal data packet;

(1) if the transmission layer of the consumer is down after receiving the response signal data packet or during receiving, the consumer loses the communication capability and directly finishes the communication;

5. And after receiving the response signal data packet, the application layer of the consumer computer analyzes the response signal data packet.

(1) If the application layer of the consumer computer unpacks the packet, the packet head, the packet tail, the CRC check and any field data in the data are incorrect, the packet unpacking is judged to be failed, namely, the data transmission is wrong; at this time, the application layer of the consumer machine discards the received data; then, the application layer of the consumer computer sends an analysis failure response packet to the terminal through the transmission layer, the application layer enters a receiving state, waits for receiving the response signal data packet again, and starts a countdown waiting for receiving;

(2) and after receiving the analysis failure response packet, the application layer cancels the receiving countdown and then analyzes the analysis failure response packet. After successful analysis, whether the failure response packet is received three times continuously is judged. If not, the response signal data packet is retransmitted; if the application layer of the terminal recognizes that the analysis failure response packet is received for three times continuously, the transmission failure is judged, and then the communication is ended;

(3) at this time, the application layer of the consumer machine judges that the receiving is overtime because the receiving countdown is finished and no receiving is carried out, and then the communication is finished;

6. If the application layer of the consumer machine successfully analyzes the response signal data packet, the terminal is judged to successfully receive the last packet of data; thus, the consuming machine deletes the previous packet of data from the consuming machine.

(3) at this point there is no loss or duplication of data.

7. The application layer of the consumer machine can judge whether data which needs to be sent exist, if the data which needs to be sent do not exist, the application layer of the consumer machine can send a null data packet, and the null data packet is transmitted to the terminal through the transmission layer.

8. After receiving the empty data packet, the transmission layer of the terminal transmits the empty data packet to the application layer, and the application layer cancels the countdown when receiving the empty data packet; and then the application layer of the terminal unpacks the data packet, after the unpacking is successful, the data is judged to be completely received, a response signal data packet is returned and sent to the consumer machine through the transmission layer, and then the application layer finishes the communication.

9. The transmission layer of the consumer receives the post-acknowledgement signal data packet and transmits the post-acknowledgement signal data packet to the application layer. The application layer cancels the countdown when receiving the packet; then, the application layer of the consumer computer unpacks the response signal data packet, and after the unpacking is successful, the communication is also ended.

10. A complete transmission is thus completed.
