Based on the display abnormality detection device of the POS machine, an embodiment of the invention provides a display abnormality detection method of the POS machine, and referring to fig. 2, fig. 2 is a flow chart of a first embodiment of the display abnormality detection method of the POS machine according to the invention.
In this embodiment, the method for detecting abnormal display of the POS machine includes the following steps:
step S10: acquiring initial display information of a POS machine at the current moment and a transaction flow corresponding to the POS machine, and carrying out information matching on the initial display information and the transaction flow.
It should be noted that, the execution body of the embodiment may be a computing service device, such as a computer, with functions of data processing, network communication and program running, or an electronic device or a display abnormality detection device of a POS device, which can implement the above functions. The present embodiment and the following embodiments will be described below with reference to the display abnormality detection device of the POS machine.
It is understood that the initial display information refers to information displayed on a screen of the POS machine at the current time, for example, information such as connection request, card number input request, etc. The transaction flow refers to the flow of the POS machine at the current moment in the use process, and the transaction flow can comprise: 1. turning on a POS machine power supply, and inputting an operation number and a corresponding password; 2. after the input is finished, the user goes to a POS machine card swiping interface; 3. after 'confirm', input '1' and choose to consume; 4. after the consumption amount is input, the user presses the 'confirmation' and then goes to a 'please insert or swipe card' interface; 5. firstly, operating to swipe the magnetic stripe card, enabling the side, provided with the magnetic stripe, of the bank card to face the POS machine, then placing the bank card into a groove of the POS machine, and pulling the bank card from top to bottom; 6. the POS machine reads the card number of the bank card and presses the confirmation after no error; 7. after the POS machine finishes the paper output, the transaction is completed.
In a specific implementation, the embodiment may match the initial display information with the transaction flow, specifically, may obtain the information that should be displayed by the transaction flow of the POS machine at the current time, for example, in the 4 th transaction step, the information that should be displayed is the input consumption amount, after the "confirm" is pressed, the information that should be displayed is the "please insert card or swipe card", and then the information that should be displayed is compared with the initial display information, if the initial display information is basically the same, the matching is illustrated to be successful, if the initial display information is completely different, the matching is illustrated to be failed, and at this time, the POS machine may have abnormal display.
Step S20: and when the matching fails, acquiring input information input to the POS machine by a user before the current moment.
It can be understood that when the matching between the initial display information and the transaction flow fails, it can be initially determined that the POS machine may have abnormal display, and at this time, information input to the POS machine by the user at all times before the current time, that is, input information, is input to the POS machine by the user at all times between the current time and the time of starting the transaction, where the time of starting the transaction is the time of starting the transaction on the POS machine for the same bank card corresponding to the current time.
Further, in order to display the complete information on the POS machine, in this embodiment, before step S20, the method further includes: when the matching is successful, judging whether the missing display information type exists in the initial information type corresponding to the initial display information according to the transaction information type corresponding to the transaction flow; if yes, acquiring missing display information corresponding to the display information type; and displaying the missing display information on the POS machine.
It should be understood that when the matching is successful, it is indicated that there is no abnormal display condition of the POS machine, but a situation may occur in which part of the information is not displayed, in order to display the complete information on the POS machine, in this embodiment, the transaction information types corresponding to the transaction flows may be obtained, the transaction information types corresponding to the different transaction flows may be different, and it may be determined that the transaction information types corresponding to the transaction information are "please insert or swipe cards", for example, the transaction information types may be request types, and the initial display information may also correspond to the initial information types.
In a specific implementation, whether the missing display information type exists in the initial information type can be judged, namely, the initial information type is matched with the transaction information type, the information types except the initial information type in the transaction information type are used as the missing display information type, missing display information corresponding to the display information type is obtained, for example, when the missing display information type is a connection state type, the corresponding missing display information can be obtained to be in connection, connection is successful, and the like, and the missing display information is displayed on a POS machine.
Step S30: and detecting abnormal display of the POS machine according to the initial display information and the input information.
It can be understood that in this embodiment, further display abnormality detection can be performed on the POS machine according to the initial display information and the input information, specifically, information that should be displayed at the current moment can be obtained approximately according to the input information, and the information is matched with the initial display information, so as to perform display abnormality detection on the POS machine.
According to the embodiment, the initial display information of the POS machine at the current moment and the corresponding transaction flow of the POS machine are obtained, the initial display information is matched with the transaction flow in information, when the matching fails, the input information input to the POS machine by a user before the current moment is obtained, and then abnormal display detection is carried out on the POS machine according to the initial display information and the input information. According to the embodiment, through matching the initial display information of the POS machine at the current moment with the transaction flow of the POS machine, whether the initial display information on the POS machine is normal or not can be primarily judged, when matching fails, namely, the POS display is possibly abnormal, the POS machine is subjected to display abnormality detection according to the initial display information and the input information input to the POS machine by a user, the POS machine can be subjected to display abnormality detection again according to the input information, and therefore accuracy of display abnormality detection of the POS machine can be improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a method for detecting abnormal display of a POS machine according to the present invention.
Based on the first embodiment, in this embodiment, the step S10 includes:
step S101: acquiring an initial display image of the POS machine at the current moment, and performing character recognition on the initial display image through a convolutional neural network to acquire initial display information.
It should be understood that the initial display image refers to an image displayed on a screen of the POS machine at the current moment, and when the POS machine is detected for abnormal display, the initial display image can be obtained through a camera, and the initial display image can be intercepted through a screenshot plug-in installed inside the POS machine.
In a specific implementation, the initial display image may be text-identified by a convolutional neural network, which may be a CRNN network, an ABCNet network, or the like. The characters, numbers and the like on the initial display image can be identified through the network, so that initial display information is obtained.
Step S102: acquiring state information of the POS machine at the current time, and determining a transaction flow corresponding to the POS machine according to the state information.
It can be understood that the state information may refer to information related to a state of the POS machine at a current time, and may include interface information, card insertion port information, connection information, and the like, and may determine a transaction flow in which the POS machine is located at the current time according to the state information.
Further, in order to effectively obtain the transaction flow corresponding to the POS machine, in this embodiment, the step S102 includes: acquiring state information of the POS machine at the current time, wherein the state information comprises: interface information and card insertion port information; judging whether the POS machine is in a normal running state according to the interface information; if yes, determining the transaction state of the POS machine according to the card inserting port information; and determining a transaction flow corresponding to the POS machine according to the transaction state and the request state between the POS machine and the transaction party.
It should be understood that, in this embodiment, the status information may include interface information and card socket information, and the interface of the POS machine may include a USB interface, an ethernet interface, a serial interface, etc., and the interface information may include an interface in a working state on the POS machine, and may also include information such as whether the interface is used normally. The POS machine can also be judged whether to be in a normal running state according to the interface information, specifically, the POS machine is indicated to be in the normal running state when the POS machine is normally connected to a network or a router through an Ethernet interface, and the POS machine is indicated to be in the normal running state when the POS machine is normally connected to the printer, the bar code scanner and other equipment through a USB interface if the POS machine is required to be connected to the printer, the bar code scanner and other equipment.
It can be understood that when the POS machine is in a normal running state, the transaction state of the POS machine can be determined according to the card insertion port information, the transaction state can include a state before transaction, during transaction, after transaction, and the like, when the card insertion port information is a bank card, the transaction state can be a state during transaction or a state after transaction, at this time, whether the POS machine has interaction with a transaction party can be judged, the transaction party can be a bank or the like, if the POS machine has interaction with the transaction party, the transaction state is the state during transaction, if the POS machine has no interaction with the transaction party, the transaction state is the state after transaction; when the card insertion port information is that the bank card does not exist, the transaction state may be a pre-transaction state or a post-transaction state, at this time, whether the POS machine receives information such as a bank card password input by a user or not can be judged, if the information is not received, the transaction state is indicated to be the pre-transaction state, and if the information is received, the transaction state is indicated to be the post-transaction state.
In a specific implementation, the request state refers to a state when interaction occurs between the POS machine and the transaction party, for example, the POS machine sends a request to the transaction party to perform a service such as consumption, or the transaction sends a request to the POS machine to remind that the transaction is completed. And determining a transaction flow corresponding to the POS machine according to the transaction state and the request state, for example, the transaction state is in transaction, the request state is POS and a request is sent to a transaction party, and the transaction flow can be transaction after the POS machine reads the card number of the bank card.
Step S103: and determining transaction display information corresponding to the transaction flow according to the model information of the POS machine, and carrying out information matching on the transaction display information and the initial display information.
It can be understood that, for different POS devices, the displayed information may also be different, and in this embodiment, the model information of the POS device may be obtained first, then the transaction display information corresponding to each transaction flow under the model information, that is, the transaction display information that should be displayed by each transaction flow corresponding to the model information, is determined, and the transaction display information and the initial display information are matched in information.
Further, in order to effectively perform information matching, in this embodiment, the step S103 includes: determining transaction display information corresponding to the transaction flow according to the model information of the POS machine, and determining a transaction information type corresponding to the transaction display information; determining an initial information type corresponding to the initial display information; when the initial information type exists in the transaction information types, judging that the matching is passed; and when the initial information type does not exist in the transaction information type, judging that the matching fails.
It should be understood that, for the transaction display information corresponding to each transaction flow, the type corresponding to the transaction display information is the transaction information type, and the initial information type corresponding to the initial display information is determined. When the initial information type exists in the transaction information type, namely, only one type is the same between the transaction information type and the initial information type, the matching can be judged to pass, and when the initial information type does not exist in the transaction information type, the matching can be judged to fail.
According to the embodiment, the initial display image of the POS machine at the current time is obtained, the initial display image is subjected to character recognition through the convolutional neural network, initial display information is obtained, then state information of the POS machine at the current time is obtained, a transaction flow corresponding to the POS machine is determined according to the state information, transaction display information corresponding to the transaction flow is determined according to model information of the POS machine, and the transaction display information is matched with the initial display information. According to the embodiment, the initial display image is subjected to character recognition through the convolutional neural network, so that the initial display information of the POS machine can be accurately obtained, the transaction flow of the POS machine can be accurately obtained according to the state information, and the transaction display information corresponding to the transaction flow is subjected to information matching with the initial display information, so that information matching can be effectively carried out.
Referring to fig. 4, fig. 4 is a flowchart illustrating a third embodiment of a method for detecting abnormal display of a POS machine according to the present invention.
Based on the above embodiments, in this embodiment, the step S30 includes:
step S301: and determining the input type corresponding to the input information, and acquiring the time interval between the input time corresponding to the input information and the current time.
It is understood that the input type refers to a type corresponding to input information, for example, when the input information is a six-digit number, the corresponding input type is a password. The time interval refers to the interval between the time of input of information by the user to the POS machine and the current time.
Step S302: and determining target display information corresponding to the POS machine according to the time interval and the input type.
It should be noted that the target display information refers to information that should be displayed by the POS machine, and may be specifically determined according to a time interval and an input type.
Further, in order to effectively obtain the target display information, in this embodiment, the step S302 includes: determining transaction duration between the POS machine and the transaction party according to historical data transmitted by the POS machine and the transaction party; judging whether the transaction is completed or not according to the time interval and the transaction duration; if yes, determining a target display type according to the input type, and determining target display information corresponding to the target display type.
It should be understood that the historical data may be data transmitted during a previous transaction process to complete a transaction, may be data transmitted between the POS machine and the transaction party during a previous day and a previous two days, and may determine a transaction duration according to the historical data, specifically, the transaction duration may be obtained according to a data amount and a data length corresponding to the historical data transmitted during the completion of a transaction, and generally, the greater the data amount and the longer the data length, the longer the required transaction duration may be, and in this embodiment, the mapping relationship between the data amount, the data length and the transaction duration may be preset, so that the transaction duration may be obtained according to the mapping relationship, and the transaction duration may be in a range.
It is appreciated that when the time interval is less than the transaction duration, it may be determined that the transaction is not complete; when the time interval is greater than the transaction duration, it may be determined that the transaction has been completed. When the transaction is completed, the target display type may be determined according to the input type, for example, when the input type is a password, the corresponding target display type may be a transaction state type, and the corresponding target display information may be in the transaction, specifically, the target display information is related to the model information of the POS machine.
Step S303: and matching the initial display information with the target display information, and detecting abnormal display of the POS machine according to a matching result.
It should be appreciated that the process of matching the initial display information to the target display information may refer to the process of matching the initial display information to the transaction display information described above. When the initial display information is successfully matched with the target display information, judging that the POS machine has no abnormal display; when the initial display information and the target display information fail to be matched, the POS machine can be judged to have abnormal display.
According to the embodiment, the input type corresponding to the input information is determined, the time interval between the input time corresponding to the input information and the current time is obtained, then the target display information corresponding to the POS machine is determined according to the time interval and the input type, then the initial display information and the target display information are matched, and the POS machine is subjected to abnormal display detection according to the matching result. According to the embodiment, the target display information corresponding to the POS machine is determined according to the time interval and the input type, the information which the POS machine should display at the current moment can be accurately obtained, and then the POS machine is subjected to abnormal display detection according to the matching result between the initial display information and the target display information, so that the accuracy of abnormal display detection of the POS machine can be improved.
