Detailed Description
In order to make the technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a flowchart of a communication exception handling method according to an embodiment of the present invention. The embodiment of the invention provides a communication abnormity processing method aiming at the problems that at present, a user can only process the fault by forcibly disconnecting the electrical connection between the intelligent card terminal and the intelligent card, but the intelligent card needs to be plugged or unplugged or the intelligent card terminal needs to be restarted to reestablish the electrical connection between the intelligent card terminal and the intelligent card terminal, so that the user data is easily lost, the operation is inconvenient and a large amount of time is consumed. As shown in fig. 1, the method comprises the following specific steps:
and S101, the intelligent card terminal and the intelligent card perform interaction of preset detection messages, and whether the interaction with the intelligent card is abnormal or not is determined according to an interaction result.
The format of the preset detection message can be preset by a technician, and the preset detection message can be an interactive message which can be identified by the smart card terminal and the smart card, and is used for detecting whether the interaction between the smart card terminal and the smart card is normal. For example, the preset detection message may be a heartbeat message, or a character string, etc.
In this embodiment, the data transmission channel used by the smart card terminal and the smart card for performing the interaction of the preset detection message is a data transmission channel used by the smart card terminal and the smart card for completing the task delivered by the user, and if the interaction of the preset detection message is abnormal, it can be estimated that the interaction of other data through the same data transmission channel is also abnormal.
In this step, the smart card terminal may determine that the interaction with the smart card is abnormal if it is determined that the interaction with the smart card is abnormal according to the result of the interaction of the preset detection message with the smart card, and may determine that the interaction with the smart card is not abnormal if it is determined that the interaction with the smart card is not abnormal.
And S102, if the intelligent card terminal determines that the interaction with the intelligent card is abnormal, sending a reset instruction to the intelligent card so as to reset the intelligent card.
The method and the device are suitable for the scene that the software of the intelligent card is abnormal or the software of the intelligent card terminal is abnormal due to factors such as overweight load of the intelligent card or overweight load of the intelligent card terminal, interaction between the intelligent card terminal and the intelligent card is abnormal, and the hardware of a data transmission channel between the intelligent card terminal and the intelligent card is not abnormal.
In this embodiment, when the smart card terminal detects that the interaction with the smart card is abnormal, the smart card terminal sends a reset instruction to the smart card, so that the smart card automatically resets according to the received reset instruction, so as to reestablish a data transmission channel between the smart card terminal and the smart card, and thus the interaction between the smart card terminal and the smart card returns to normal.
In this embodiment, the process of automatically resetting the smart card may be implemented by using a reset mechanism corresponding to the smart card in the prior art, and since a data protection measure, such as normal shutdown of an ongoing task, is taken before the smart card is reset, data loss may be avoided.
Optionally, a higher priority may be set for the reset instruction to implement that the smart card suspends the execution of other tasks and preferentially responds to the reset instruction. For example, the priority of the reset instruction may be preset to the highest level, so that when the smart card receives the reset instruction, the smart card stops all other processes and preferentially performs automatic reset.
According to the embodiment of the invention, whether the interaction of the preset detection message with the intelligent card is abnormal is monitored by the intelligent card terminal, and the reset instruction is sent to the intelligent card when the interaction with the intelligent card is determined to be abnormal, so that the intelligent card is automatically reset according to the reset instruction, the intelligent card terminal and the intelligent card do not need to be forcibly disconnected by plugging and unplugging the intelligent card or restarting the intelligent card terminal, the operation is convenient and fast, and the condition that the data is lost due to the fact that the electrical connection between the intelligent card terminal and the intelligent card is forcibly disconnected is avoided.
Example two
Fig. 2 is a flowchart of a communication exception handling method according to a second embodiment of the present invention. On the basis of the first embodiment, in the embodiment of the present invention, the smart card terminal sends the reset instruction to the smart card to reset the smart card, and the following method may be adopted: the intelligent card terminal sends a local reset instruction to the intelligent card so that the intelligent card restarts the processing process of the current task according to the local reset instruction; the intelligent card terminal receives a local reset response instruction fed back by the intelligent card; and if the intelligent card terminal determines that the intelligent card is failed to reset locally according to the local reset response instruction, sending a card reset instruction to the intelligent card so as to restart the intelligent card. As shown in fig. 2, the method comprises the following specific steps:
step S201, the intelligent card terminal and the intelligent card carry out interaction of preset detection messages, and whether the interaction with the intelligent card is abnormal or not is determined according to an interaction result.
In this embodiment, the smart card terminal performs interaction of the preset detection message with the smart card, and determines whether the interaction with the smart card is abnormal according to the interaction result, which may specifically be implemented in any one of the following manners:
(1) the intelligent card terminal monitors the receiving condition of the health message sent by the intelligent card, and if the intelligent card terminal does not receive the health message within the preset time interval, the intelligent card terminal determines that the interaction with the intelligent card is abnormal.
Specifically, the preset time interval refers to a preset time interval for sending the health message.
In this embodiment, when the detection is started, the smart card sends a piece of health message to the smart card terminal at preset time intervals, and if the smart card terminal receives the piece of health message within the preset time intervals, the smart card terminal continues to receive the next piece of health message until a preset number of health messages are received on time, and it can be determined that no abnormality occurs in the interaction with the smart card; if the smart card terminal does not receive the corresponding health message within the preset time interval, it may be determined that the interaction with the smart card is abnormal. The preset time interval and the preset number may be preset by a technician, which is not specifically limited in this embodiment.
For example, the predetermined time interval is 1 second and the predetermined number is 3. When the detection is started, the smart card sends a first health message to the smart card terminal, and sends a health message to the smart card terminal every 1 second. If the smart card terminal receives a first health message sent by the smart card in the first 1 second after the detection is started, receives a second health message sent by the smart card in the second 1 second after the detection is started, and receives a third health message sent by the smart card in the third 1 second after the detection is started, it can be determined that no abnormality occurs in the interaction between the smart card terminal and the smart card. If the receiving condition of the health message sent by the intelligent card is monitored by the intelligent card terminal, the first health message sent by the intelligent card is not received within the first 1 second after the detection is started; or the intelligent card terminal receives a first health message sent by the intelligent card within the first 1 second after the detection is started and does not receive a second health message sent by the intelligent card within the second 1 second after the detection is started; or, if the smart card terminal receives a first health message sent by the smart card within the first 1 second after the detection is started, receives a second health message sent by the smart card within the second 1 second after the detection is started, and does not receive a third health message sent by the smart card within the third 1 second after the detection is started, it can be determined that no health message is received within a preset time interval, and the smart card terminal determines that the interaction with the smart card is abnormal.
(2) The intelligent card terminal sends a detection message to the intelligent card, and if the intelligent card terminal determines that the response message sent by the intelligent card is not received within the preset time, the intelligent card terminal determines that the interaction with the intelligent card is abnormal.
Specifically, the intelligent card terminal actively sends a detection message to the intelligent card so that the intelligent card feeds back a response message to the intelligent card terminal after receiving the detection message; if the smart card terminal does not receive a response message sent by the smart card within a preset time length, determining that the interaction with the smart card is abnormal; and if the smart card terminal receives the response message sent by the smart card within the preset time, determining that no abnormity occurs in the interaction with the smart card.
In order to more accurately determine the interaction abnormality of the smart card terminal and the smart card, after determining that the interaction abnormality occurs, the repeated confirmation may be performed in the manner of (2).
(3) The intelligent card terminal monitors the receiving condition of the health message sent by the intelligent card, if the health message is determined not to be received within a preset time interval, the intelligent card terminal sends a detection message to the intelligent card, and if the response message sent by the intelligent card is determined not to be received within a preset time length, the intelligent card terminal determines that the interaction with the intelligent card is abnormal.
And (3) combining the two modes (1) and (2), in order to more accurately determine the interaction abnormity between the intelligent card terminal and the intelligent card, after the interaction abnormity between the intelligent card terminal and the intelligent card is determined through the mode (1), the intelligent card terminal is determined again through the mode (2) so as to avoid false alarm of the interaction abnormity between the intelligent card terminal and the intelligent card.
Step S202, if the intelligent card terminal determines that the interaction with the intelligent card is abnormal, the intelligent card terminal sends a local reset instruction to the intelligent card so that the intelligent card restarts the processing process of the current task according to the local reset instruction.
Specifically, the smart card terminal sends a local reset instruction to the smart card, so that the smart card performs local reset according to the local reset instruction after receiving the local reset instruction, and feeds back a local reset response instruction.
In this embodiment, when the smart card terminal determines that the interaction with the smart card is abnormal, the smart card terminal first controls the smart card to perform local reset, that is, restarts the processing process of the current task, instead of directly controlling the reset of the smart card, so as to solve the problem of abnormal interaction between the smart card terminal and the smart card caused by the execution of the current task, and if the problem of abnormal interaction can be solved by local reset of the smart card, the forced stop of the smart card terminal and other tasks being executed by the smart card terminal can be avoided, thereby avoiding the loss of data.
And S203, the intelligent card terminal monitors a local reset response instruction fed back by the intelligent card.
In this embodiment, after the smart card terminal sends the local reset instruction to the smart card, the smart card may feed back a local reset response instruction to the smart card terminal after receiving the local reset.
In this step, the smart card terminal monitors a local reset response instruction sent by the smart card to determine whether the local reset is successful or not.
And step S204, if the intelligent card terminal determines that the local reset response instruction fed back by the intelligent card is not received within the preset waiting time, or if the intelligent card terminal determines that the local reset of the intelligent card fails according to the received local reset response instruction fed back by the intelligent card, the intelligent card terminal sends a card reset instruction to the intelligent card so as to restart the intelligent card.
The local reset response instruction carries the result of the local reset of the intelligent card, and the intelligent card feeds back the result of whether the local reset is successful or not to the intelligent card terminal after the local reset is carried out.
In this embodiment, the local reset result carried by the local reset response instruction received by the smart card terminal and fed back by the smart card is a failure, which may determine that the local reset of the smart card has failed, and the smart card terminal sends a card reset instruction to the smart card, so that the smart card is restarted to solve the problem of interaction anomaly.
If the smart card terminal does not receive the local reset response instruction fed back by the smart card within the preset waiting time, the smart card terminal can determine that the interaction between the smart card terminal and the smart card is still abnormal, and then the smart card terminal sends a card reset instruction to the smart card so as to restart the smart card, thereby solving the problem of abnormal interaction.
Optionally, if the smart card terminal does not receive the local reset response instruction fed back by the smart card within the preset waiting time, the smart card terminal may repeatedly execute steps S202-S204, if the smart card terminal does not receive the local reset response instruction fed back by the smart card within the preset waiting time in this execution, the steps S202-S204 are repeatedly executed until the number of times of executing the steps S202-S204 reaches the preset local reset number, and if the local reset response instruction fed back by the smart card is not received within the preset waiting time, a reset instruction is sent to the smart card to reset the smart card, so that false alarm of interaction abnormality between the smart card terminal and the smart card may be avoided.
Optionally, before sending the card reset instruction to the smart card, the smart card terminal queries whether the user allows immediate smart card reset, and if the user confirms the smart card reset instruction, the smart card terminal sends the card reset instruction to the smart card so as to restart the smart card; if the intelligent card reset instruction rejected by the user is received, the intelligent card terminal prompts the user that the interaction between the intelligent card terminal and the intelligent card is abnormal, and the card reset instruction is not sent to the intelligent card, so that the problem that the important task being executed is forcibly closed, data loss is caused, and huge loss is brought to the user is avoided. In addition, after receiving the instruction that the user refuses the reset of the smart card, the smart card terminal can stop detecting whether the interaction with the smart card is abnormal or not so as to reduce the occupation of interaction resources.
The embodiment of the invention provides three implementation modes of determining whether the interaction with the intelligent card is abnormal by the intelligent card terminal, wherein when the interaction with the intelligent card is determined to be abnormal, the intelligent card terminal firstly controls the intelligent card to carry out local reset and restarts the processing process of the current task, thereby avoiding the forced stop of the intelligent card terminal and other tasks being executed by the intelligent card; if the intelligent card terminal determines that the local reset of the intelligent card fails or determines that the interaction abnormality with the intelligent card still exists, the intelligent card is controlled to be restarted to reestablish the electrical connection between the intelligent card terminal and the intelligent card, so that the intelligent card terminal and the intelligent card are not required to be forcibly disconnected by plugging and unplugging the intelligent card or restarting the intelligent card terminal, the operation is convenient and fast, and the data loss caused by the forced disconnection of the electrical connection is avoided.
EXAMPLE III
Fig. 3 is a flowchart of a communication exception handling method according to a third embodiment of the present invention. On the basis of any of the above embodiments, in the embodiments of the present invention, before the smart card terminal performs interaction of the preset detection message with the smart card, a process of starting the anomaly detection is further included. As shown in fig. 3, the method comprises the following specific steps:
and S301, the intelligent card terminal sends an abnormity detection starting instruction to the intelligent card.
In this embodiment, before the smart card terminal and the smart card perform interaction of the preset detection message, an anomaly detection starting instruction is sent to the smart card to notify the smart card to start anomaly detection, so that the smart card terminal and the smart card start interaction of the preset detection message, and a function of communication anomaly handling is started.
In addition, the communication exception handling function state may be used to indicate whether the function of the communication exception handling is on or off, and is set to an on state after the function of the communication exception handling is started, and is set to an off state after the function of the communication exception handling is turned off. The communication exception handling function state may be stored on the smart card terminal, or the communication exception handling function state may be stored on a dedicated management server, which manages the communication exception handling function states of a plurality of different smart card terminals.
In this embodiment, the starting node for sending the abnormal detection starting instruction to the smart card by the smart card terminal may be preset, and the starting node at least includes the following components: after the intelligent card terminal completes the establishment of a data transmission channel with the intelligent card, an abnormal detection starting instruction is sent to the intelligent card; or when the intelligent card terminal interacts with the intelligent card, an abnormal detection starting instruction is sent to the intelligent card; or when the intelligent card terminal receives a starting instruction input by a user, the intelligent card terminal sends an abnormity detection starting instruction to the intelligent card.
Optionally, before the smart card terminal sends the abnormal detection starting instruction to the smart card, determining whether data interaction is being performed with the smart card; and if the data interaction with the intelligent card is determined, sending an abnormal detection starting instruction to the intelligent card after the data interaction is finished so as to avoid influencing the efficiency of completing the task delivered by the user by the intelligent card terminal and the intelligent card.
And step S302, the intelligent card terminal monitors a response instruction of starting the abnormal detection sent by the intelligent card.
In this embodiment, after the smart card terminal sends the anomaly detection starting instruction to the smart card, and after the smart card receives the anomaly detection starting instruction, the smart card terminal may feed back a start anomaly detection response instruction to the smart card terminal.
In this step, the smart card terminal monitors a start anomaly detection response instruction sent by the smart card to determine whether anomaly detection is successfully started.
Step S303, if the smart card terminal does not receive the start anomaly detection response instruction within the preset time range, determining that the interaction with the smart card is abnormal, and sending a reset instruction to the smart card so as to reset the smart card.
The preset time range is allowed waiting time for the intelligent card terminal to wait for the start of the abnormal detection.
In this step, if the smart card terminal does not receive the start anomaly detection response instruction within the preset time range, it may determine that the interaction with the smart card is abnormal, and send a reset instruction to the smart card, so as to reset the smart card, which may specifically be implemented in the following manner:
the intelligent card terminal sends a local reset instruction to the intelligent card so that the intelligent card restarts the processing process of the current task according to the local reset instruction; if the intelligent card terminal determines that the local reset response instruction fed back by the intelligent card is not received within the preset waiting time or if the intelligent card terminal determines that the local reset of the intelligent card fails according to the received local reset response instruction fed back by the intelligent card, the intelligent card terminal sends a card reset instruction to the intelligent card so as to restart the intelligent card.
In this embodiment, if the smart card terminal does not receive the start anomaly detection response instruction within the preset time range, it may determine that the interaction with the smart card is abnormal, and send a reset instruction to the smart card, so that the specific implementation manner of resetting the smart card is similar to the process of steps S202 to S204 in the second embodiment, which is not described herein again.
Optionally, in this step, if the smart card terminal does not receive the start anomaly detection response instruction within the preset time range, the smart card terminal repeatedly executes the steps S301 to S303, and if the smart card terminal receives the start anomaly detection response instruction within the preset time range in this execution, the step S304 is executed, and the smart card terminal and the smart card perform interaction of a preset detection message; otherwise, if the smart card terminal does not receive the start anomaly detection response instruction within the preset time range in the execution, the steps S301-S303 are repeatedly executed until the times of executing the steps S301-S303 reach the preset repeated times, and if the interaction anomaly with the smart card is still determined, a reset instruction is sent to the smart card to reset the smart card, so that the false alarm of the interaction anomaly between the smart card terminal and the smart card can be avoided.
And step S304, if the smart card terminal receives the response command for starting the abnormal detection in the preset time range, the smart card terminal and the smart card carry out interaction of preset detection information, and whether the interaction with the smart card is abnormal or not is determined according to an interaction result.
In this step, the process of interacting the preset detection message between the smart card terminal and the smart card and determining whether the interaction with the smart card is abnormal according to the interaction result is the same as step S201 in the second embodiment, and details are not repeated here.
And S305, if the intelligent card terminal determines that the interaction with the intelligent card is abnormal, sending a reset instruction to the intelligent card so as to reset the intelligent card.
The step can be specifically realized by adopting the following mode:
the intelligent card terminal sends a local reset instruction to the intelligent card so that the intelligent card restarts the processing process of the current task according to the local reset instruction; if the intelligent card terminal determines that the local reset response instruction fed back by the intelligent card is not received within the preset waiting time or if the intelligent card terminal determines that the local reset of the intelligent card fails according to the received local reset response instruction fed back by the intelligent card, the intelligent card terminal sends a card reset instruction to the intelligent card so as to restart the intelligent card.
The specific implementation manner of this step in this embodiment is similar to the process of steps S202 to S204 in the second embodiment, and this embodiment is not described herein again.
According to the embodiment of the invention, the process of starting the abnormal detection is added before the intelligent card terminal and the intelligent card interact with the preset detection message, so that the time for detecting the abnormal interaction between the intelligent card terminal and the intelligent card can be set, and the continuous interaction of the preset detection message when the abnormal interaction between the intelligent card terminal and the intelligent card does not occur is avoided, thereby reducing the occupied interactive resources and improving the completion efficiency of the intelligent card terminal and the intelligent card on the task delivered by the user.
Example four
Fig. 4 is a flowchart of a communication exception handling method according to a fourth embodiment of the present invention. On the basis of any one of the above embodiments, in the embodiment of the present invention, the smart card terminal sends an anomaly detection closing instruction to the smart card to stop interaction of the smart card terminal and the smart card for a preset detection message, thereby stopping the communication anomaly handling process. As shown in fig. 4, the method comprises the following specific steps:
and S401, the intelligent card terminal sends an abnormal detection closing instruction to the intelligent card.
