The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Fig. 1 is a schematic flow chart of a maintenance early warning method for a card reader device according to a first embodiment of the present invention, and as shown in fig. 1, the maintenance early warning method for a card reader device according to the embodiment of the present invention includes:
s101, acquiring state data of card reader equipment, wherein the state data comprises a plurality of first state parameters;
specifically, when the card reader device is used, the real-time recording data of the card reader device may be sent to a server, and the server may acquire the state data of the card reader device according to the real-time recording data of the card reader device.

The status data may include a plurality of first status parameters, and the first status parameters may include parameters such as the number of times of card swiping success of the magnetic stripe, the total number of times of card swiping of the magnetic stripe, the number of times of card swiping success of the contact IC card, the total number of times of card swiping of the contact IC card, the response time of card swiping of each time of the radio frequency IC card, the number of times of success of reading the identification card, the total number of times of reading the identification card, the response time of reading each time of the identification card, and the like. The real-time recording data is real-time data generated when the card reader device works, such as response time of card swiping, whether card swiping succeeds, reading time of an identity card, whether the identity card succeeds, the working temperature of the whole machine, the working voltage of the whole machine and the like, and is set according to actual needs, and the embodiment of the invention is not limited. The executing body of the maintenance early warning method of the card reader device provided by the embodiment of the invention comprises but is not limited to a server.
S102, obtaining at least one early warning parameter according to each first state parameter;
specifically, after the server obtains that the state data includes a plurality of first state parameters, at least one early warning parameter may be obtained according to each first state parameter. The early warning parameters may be a card swiping success rate of the magnetic stripe card, a card swiping success rate of the contact IC card, an average response time of card swiping of the radio frequency IC card, a reading success rate of the identity card, and an average response time of reading the identity card, and are set according to actual situations, which is not limited in the embodiments of the present invention.
S103, if the early warning parameters are judged to exceed the corresponding threshold value range, first early warning information is sent.
Specifically, after the server obtains the at least one early warning parameter, for each early warning parameter, the server may determine whether the early warning parameter exceeds a threshold range corresponding to the early warning parameter, and if the early warning parameter exceeds the corresponding threshold range, send first early warning information, and may notify relevant operation and maintenance personnel through an email or a short message, so as to maintain the card reader device corresponding to the early warning parameter in advance. Wherein the first warning information may indicate which module of the card reader device needs to be maintained.
According to the maintenance early warning method for the card reader equipment, provided by the embodiment of the invention, the state data of the card reader equipment can be obtained, at least one early warning parameter is obtained according to each first state parameter included in the state data, after the early warning parameter is judged and obtained to exceed the corresponding threshold range, the first early warning information is sent, maintenance early warning can be carried out when the card reader equipment does not meet the functional requirements, so that action is taken in advance to maintain the card reader equipment, passive maintenance is avoided when the card reader equipment breaks down, active maintenance of the card reader equipment is realized, and the reliability of the card reader equipment is improved.
On the basis of the above embodiments, further, the first state parameter includes the number of times that the magnetic stripe is successfully swiped in the card and the total number of times that the magnetic stripe is swiped in the card within a first preset time period; correspondingly, the obtaining at least one early warning parameter according to each first state parameter includes:
and if the total number of times of swiping the magnetic stripe card is larger than a first threshold value, calculating to obtain the card swiping success rate of the magnetic stripe card according to the successful number of times of swiping the magnetic stripe card and the total number of times of swiping the magnetic stripe card.
Specifically, when the card reader device includes the magnetic stripe type read-write module, the magnetic stripe card swiping record of the magnetic stripe type read-write module in use can be sent to the server in real time, the server can count the magnetic stripe card swiping success times of the magnetic stripe type read-write module in a first preset time period, obtain the magnetic stripe card swiping success times in the first preset time period, count the sum of the magnetic stripe card swiping times of the magnetic stripe type read-write module in the first preset time period, and obtain the magnetic stripe card swiping total times in the first preset time period. The first state parameters comprise the number of successful card swiping times of the magnetic stripe and the total number of card swiping times of the magnetic stripe in a first preset time period. The first preset time period is set according to actual needs, for example, set to 1 day, and the embodiment of the present invention is not limited.
After obtaining the card swiping success times and the magnetic stripe card swiping total times, the server judges whether the magnetic stripe card swiping total times is larger than a first threshold value, if the magnetic stripe card swiping total times is larger than the first threshold value, the server divides the card swiping success times by the magnetic stripe card swiping total times, and the card swiping success rate of the magnetic stripe card can be calculated. If the total number of times of swiping the magnetic stripe card is less than or equal to the first threshold value, the number of times of swiping the magnetic stripe card by the magnetic stripe type read-write module is too small, and the card swiping success rate of the magnetic stripe card does not need to be calculated. The first threshold is set according to practical experience, for example, set to 100, and the embodiment of the present invention is not limited.
After the card swiping success rate of the magnetic stripe card is obtained through calculation, whether the card swiping success rate of the magnetic stripe card is larger than or equal to a first card swiping threshold value or not can be judged, if the card swiping success rate of the magnetic stripe card is larger than or equal to the first card swiping threshold value, the card swiping success rate of the magnetic stripe type read-write module meets the functional requirement, and maintenance and early warning are not needed. If the card swiping success rate of the magnetic stripe card is smaller than the first card swiping threshold, the card swiping success rate of the magnetic stripe card is beyond the corresponding threshold range, and first early warning information needs to be sent.
For example, the card swiping success rate C of the magnetic stripe card in the first preset time period1Assuming C is the number of successful magnetic stripe card swipes/total number of magnetic stripe card swipes1When the current value is less than or equal to 75 percent, the failure of the magnetic stripe type read-write module is represented; when it is 75%<C1<When 85%, the magnetic stripe type read-write module is in an unstable working state, and maintenance early warning prompt is required; when C is present1More than or equal to 85 percent, which means that the magnetic stripe type read-write module works normally. Setting the first card swiping threshold to be 85 percent at C1When the number of the read-write modules is less than 85%, first early warning information is sent, so that active maintenance is carried out when the magnetic stripe type read-write modules are in an unstable working state, and passive maintenance is not carried out when the magnetic stripe type read-write modules are in failure, so that the reliability of the magnetic stripe type read-write modules is improved, and the influence on business handling of customers is reduced.
On the basis of the above embodiments, further, the first state parameter includes the number of times of card swiping success of contacting the IC card and the total number of times of card swiping of contacting the IC card in a second preset time period, and/or the response time of each card swiping of contacting the IC card in a third preset time period; correspondingly, the obtaining at least one early warning parameter according to each first state parameter includes:
if the total card swiping times of the contact IC card are judged to be larger than a second threshold value, calculating the card swiping success rate of the contact IC card according to the card swiping success times of the contact IC card and the total card swiping times of the contact IC card; and/or
And calculating and obtaining the average response time of the card swiping of the contact IC card according to the response time of each card swiping of the contact IC card in the third preset time period.
Specifically, when the card reader device includes the contact IC card reading and writing module, the contact card reading record of the contact IC card reading and writing module during use and the response time of each card reading can be sent to the server in real time, and the server can count the card reading success times of the contact IC card reading and writing module in a second preset time period, obtain the card reading success times of the contact IC card in the second preset time period, count the sum of the card reading times of the contact IC card reading and writing module in the second preset time period, and obtain the total card reading times of the contact IC card in the second preset time period. The server can also acquire the response time of each card swiping when the IC card is contacted in a third preset time period. The first state parameter can comprise the card swiping success times of contacting the IC card and the total card swiping times of contacting the IC card in a second preset time period, and/or the card swiping response time of contacting the IC card in a third preset time period. The second preset time period is set according to actual needs, for example, set to 1 day, and the embodiment of the present invention is not limited. The third preset time period is set according to actual needs, for example, set to 1 day, and the embodiment of the present invention is not limited.
After obtaining the card swiping success times of the contact IC card and the card swiping total times of the contact IC card, the server judges whether the card swiping total times of the contact IC card is larger than a second threshold value or not, if the card swiping total times of the contact IC card is larger than the second threshold value, the server divides the card swiping success times of the contact IC card by the card swiping total times of the contact IC card, and the card swiping success rate of the contact IC card can be calculated. If the total card swiping times of the contact IC card are less than or equal to the second threshold value, the card swiping times of the contact IC card read-write module are too few, and the card swiping success rate of the contact IC card does not need to be calculated. The second threshold is set according to practical experience, for example, set to 100, and the embodiment of the present invention is not limited.
After the card swiping success rate of the contact IC card is obtained through calculation, whether the card swiping success rate of the contact IC card is larger than or equal to a second card swiping threshold value or not can be judged, if the card swiping success rate of the contact IC card is larger than or equal to the second card swiping threshold value, the card swiping success rate of the contact IC card read-write module meets the functional requirement, and maintenance and early warning are not needed. If the card swiping success rate of the magnetic stripe card contacting the IC card is smaller than the second card swiping threshold, the card swiping success rate of the magnetic stripe card contacting the IC card is beyond the corresponding threshold range, and first early warning information needs to be sent. The second card swiping threshold is set according to practical experience, and the embodiment of the invention is not limited.
After obtaining the response time of each card swiping of the IC card in the third preset time period, the server can calculate the average value of the response time of each card swiping of the IC card in the third preset time period, and obtain the average response time of the card swiping of the IC card. The server can compare the average response time of the card swiping of the contact IC card with the first response time, and if the average response time of the card swiping of the contact IC card is greater than or equal to the first response time, it indicates that the average response time of the card swiping of the contact IC card exceeds the corresponding threshold range, and first early warning information needs to be sent. If the average response time of the card swiping of the contact IC card is shorter than the first response time, the response time of the contact IC card reading and writing module meets the functional requirement, and maintenance early warning is not needed. The first response time is set according to practical experience, and the embodiment of the present invention is not limited.
The maintenance early warning of the contact type IC card read-write module can be set according to actual needs by adopting the card swiping success rate of the contact type IC card and/or the average response time of card swiping of the contact type IC card, and the embodiment of the invention is not limited.
For example, the card-swiping success rate C of contacting the IC card in the second preset time period2Assuming that C is the number of successful card swipes for contacting the IC card/the total number of card swipes for contacting the IC card2When the current value is less than or equal to 80%, the contact type IC card read-write module is in failure; when the content is 80 percent<C2<When 90%, the contact type IC card read-write module is in an unstable working state, and maintenance early warning prompt is required; when C is present2More than or equal to 90 percent, which means that the contact type IC card read-write module works normally. Setting the second card swiping threshold to be 90 percent at C2And sending first early warning information just less than 90%, so that active maintenance is carried out when the contact type IC card read-write module is in an unstable working state, instead of passive maintenance after the contact type IC card read-write module is in a fault, the reliability of the contact type IC card read-write module is improved, and the influence on the handling of customer services is reduced.
For example, the average response time of the card swiping of the contact IC card is calculated to be t1Suppose when t is1<500 milliseconds, representing that the contact type IC card read-write module works normally; when the time is less than or equal to 500 milliseconds and less than or equal to t1Less than or equal to 1000 milliseconds, the contact type IC card read-write module is in an unstable working state, and maintenance early warning prompt is required; when t is1>1000 milliseconds, representing that the contact IC card read-write module has a fault. Setting the first response time to 500 milliseconds at t1The first early warning information is sent just when the time is more than or equal to 500 milliseconds, so that active maintenance is carried out when the contact type IC card read-write module is in an unstable working state, instead of passive maintenance after the contact type IC card read-write module is in a fault, the reliability of the contact type IC card read-write module is improved, and the influence on the business handling of customers is reduced.
On the basis of the above embodiments, further, the first state parameter includes a response time of each card swiping of the radio frequency IC card in a fourth preset time period; correspondingly, the obtaining at least one early warning parameter according to each first state parameter includes:
and calculating to obtain the average response time of the radio frequency IC card swiping according to the response time of the radio frequency IC card swiping each time in the fourth preset time period.
Specifically, when the card reader device includes the radio frequency IC card read-write module, the response time of each card swiping of the radio frequency IC card read-write module in use can be sent to the server in real time, and the server can obtain the response time of each card swiping of the radio frequency IC card in a fourth preset time period. The first state parameter may include a response time of each card swiping of the radio frequency IC card within a fourth preset time period. The fourth preset time period is set according to actual needs, for example, set to 1 day, and the embodiment of the present invention is not limited.
After obtaining the response time of each card swiping of the radio frequency IC card in the fourth preset time period, the server may calculate an average value of the response time of each card swiping of the radio frequency IC card in the fourth preset time period, so as to obtain the average response time of the card swiping of the radio frequency IC card. The server can compare the average response time of the radio frequency IC card swiping with a second response time, and if the average response time of the radio frequency IC card swiping is greater than or equal to the second response time, it indicates that the average response time of the radio frequency IC card swiping exceeds a corresponding threshold range, and first early warning information needs to be sent. And if the average response time of the radio frequency IC card swiping is less than the second response time, the response time of the radio frequency IC card reading and writing module meets the functional requirement, and maintenance early warning is not needed. The second response time is set according to practical experience, and the embodiment of the present invention is not limited.
For example, the average response time of the card swiping of the contact IC card is calculated to be t2Suppose when t is2<280 milliseconds, representing that the radio frequency IC card read-write module works normally; when the time is less than or equal to 280 milliseconds and less than or equal to t2Less than or equal to 360 milliseconds, the radio frequency IC card read-write module is in an unstable working state, and maintenance early warning prompt is required; when t is2>And 360 milliseconds, which represents that the radio frequency IC card read-write module has a fault. Setting the second response time to 280 milliseconds at t2The first early warning information is sent just when the time is more than or equal to 280 milliseconds, so that the radio frequency IC card read-write module is actively maintained in an unstable working state, and the radio frequency IC card read-write module is not passively maintained after the radio frequency IC card read-write module is in a faultAnd the reliability of the radio frequency IC card read-write module is improved, and the influence on the business handling of the client is reduced.
On the basis of the foregoing embodiments, further, the first state parameter includes the number of successful id card readings and the total number of id card readings in a fifth preset time period, and/or the response time of each id card reading in a sixth preset time period; correspondingly, the obtaining at least one early warning parameter according to each first state parameter includes:
if the total reading times of the identity card are judged to be larger than a third threshold value, calculating to obtain the reading success rate of the identity card according to the successful reading times of the identity card and the total reading times of the identity card; and/or
And calculating to obtain the average response time of reading the identity card according to the response time of reading the identity card each time in the sixth preset time period.
Specifically, when the card reader device includes the identity card reading module, the card reading record of the identity card reading module during use and the response time for reading the identity card each time can be sent to the server in real time, the server can count the number of times of success of reading the identity card by the identity card reading module in a fifth preset time period, obtain the number of times of success of reading the identity card in the fifth preset time period, count the sum of the number of times of reading the identity card by the identity card reading module in the fifth preset time period, and obtain the total number of times of reading the identity card in the fifth preset time period. The server can also acquire the response time of each reading of the identity card in a sixth preset time period. The first state parameter may include the number of successful id card readings and the total number of id card readings in a fifth preset time period, and/or the response time of each id card reading in a sixth preset time period. The fifth preset time period is set according to actual needs, for example, set to 1 day, and the embodiment of the present invention is not limited. The sixth preset time period is set according to actual needs, for example, set to 1 day, and the embodiment of the present invention is not limited.
After obtaining the number of successful reading times of the identity card and the total number of reading times of the identity card, the server judges whether the total number of reading times of the identity card is greater than a third threshold value, and if the total number of reading times of the identity card is greater than the third threshold value, the server divides the total number of reading times of the identity card by the number of successful reading times of the identity card, so that the success rate of reading the identity card can be calculated. If the total number of times of reading the identity card is less than or equal to the third threshold, the number of times of reading the identity card reading module is too small, and the success rate of reading the identity card does not need to be calculated. The third threshold is set according to practical experience, for example, set to 100, and the embodiment of the present invention is not limited.
After the reading success rate of the identity card is obtained through calculation, whether the reading success rate of the identity card is larger than or equal to a third card swiping threshold value or not can be judged, if the reading success rate of the identity card is larger than or equal to the third card swiping threshold value, the card swiping success rate of the identity card reading module meets the functional requirements, and maintenance and early warning are not needed. If the reading success rate of the identity card is smaller than the third card swiping threshold, the fact that the reading success rate of the identity card exceeds the corresponding threshold range is indicated, and first early warning information needs to be sent. The third card swiping threshold is set according to practical experience, and the embodiment of the invention is not limited.
After obtaining the response time of each reading of the identity card in the sixth preset time period, the server may calculate an average value of the response time of each reading of the identity card in the sixth preset time period, and obtain the average response time of the reading of the identity card. The server may compare the average response time read by the identity card with a third response time, and if the average response time read by the identity card is greater than or equal to the third response time, it indicates that the average response time read by the identity card exceeds a corresponding threshold range, and first warning information needs to be sent. And if the average response time of reading the identity card is less than the third response time, the response time of the identity card reading module meets the functional requirement, and the maintenance and early warning are not needed. The third response time is set according to practical experience, and the embodiment of the present invention is not limited.
For the maintenance and early warning of the identity card reading module, the reading success rate of the identity card and/or the average response time of the identity card reading can be adopted and set according to actual needs, and the embodiment of the invention is not limited.
For example, the success rate C of reading the identity card in the fifth preset time period3Assume C is the number of successful id card reads/total id card reads3When the content is less than or equal to 50%, representing that the identity card reading module has a fault; when the content is 50 percent<C3<When 85%, representing that the identity card reading module is in an unstable working state, and needing maintenance early warning prompt; when C is present3More than or equal to 85 percent, which represents that the identity card reading module works normally. Setting the third card swiping threshold to 85 percent at C3The first early warning information is sent just less than 85%, so that active maintenance is carried out when the identity card reading module is in an unstable working state, instead of passive maintenance after the identity card reading module is in a fault, the reliability of the identity card reading module is improved, and the influence on the business handling of a client is reduced.
For example, the average response time of the obtained ID card reading is calculated as t3Suppose when t is3<1200 milliseconds, which represents that the identity card reading module works normally; when 1200 milliseconds is less than or equal to t3The time is less than or equal to 1700 milliseconds, which represents that the identity card reading module is in an unstable working state and needs maintenance early warning prompt; when t is3>1700 milliseconds, representing a failure of the identification card reading module. Setting the third response time to 1200 milliseconds at t3The first early warning information is sent just when the time is more than or equal to 1200 milliseconds, so that active maintenance is carried out when the identity card reading module is in an unstable working state, instead of passive maintenance after the identity card reading module is in a fault, the reliability of the identity card reading module is improved, and the influence on the business handling of a client is reduced.
It will be appreciated that the statistical time period may be set shorter, for example 1 day, for a busy banking site where the card reader device is used frequently, and longer, for example 3 or 5 days, for a less busy banking site where the card reader device is used less frequently. The statistical time period here refers to a first preset time period, a second preset time period, a third preset time period, a fourth preset time period, a fifth preset time period and a sixth preset time period.

specifically, by preprocessing the historical record data of the past seventh preset time period of each card reading module of the card reader device, the prediction data of each card reading module can be obtained, and the server can obtain the prediction data of each card reading module of the card reader device. The card reading module can be any one of a magnetic stripe type reading and writing module, a contact type IC card reading and writing module, a radio frequency IC card reading and writing module and an identity card reading module, and the card reader equipment comprises at least one card reading module. The historical record data of each card reading module may include device data, periodic data, salary and social security data, holiday data, usage times statistical data, contemporaneous usage times data, current usage times data, average usage times data, cycle usage times data, and the like, and is set according to actual needs, which is not limited in the embodiments of the present invention. The seventh preset time period is, for example, 3 months, and is set according to actual needs, which is not limited in the embodiment of the present invention.
For example, historical data of each card reading module of the card reader device can be acquired by an internal system of a bank or a web crawler. The device data may include information about the location of the home, the home network site, the number of card reader devices in the network site, the usage window (for public or private), etc. The periodic data may include month, beginning/middle/end of month, number of days of the month, week number of the month, day of the week, etc. information. The salary and social security data may include information such as whether it is a salary day, whether it is salary for the first N days, whether it is salary for the next N days, whether it is a social security day, whether it is social security for the first N days, whether it is social security for the next N days, etc. The holiday data includes information on whether it is a holiday, whether several days in the previous N days are holidays, and whether several days in the next N days are holidays.

For example, preprocessing the history data for each card reading module may include correcting inconsistencies in the history data by filling in missing values, smoothing noise, and identifying outliers. When filling missing values, filling by adopting a mean value and a median; when the noise data and the outliers are processed, the noise data are determined through the upper edge and the lower edge of a box line graph, the outliers are detected through a clustering algorithm, then the noise data and the outliers are labeled according to specific business experience, and finally the average values of the previous period and the later period are calculated to repair the noise data and the outliers.
The preprocessing of the history data of each card reading module may comprise integrating the history data. Because the data acquired by the system has various sources, and attributes representing the same concept may have different names or units in different data sources, which may cause data inconsistency and redundancy, in the embodiment of the present invention, a method of correlation analysis may be adopted to integrate the data.
Preprocessing the history data of each card reading module can include performing a specification on the history data of each card reading module. Simplified representation of data can be obtained through reduction technology, the occupied space of the simplified data becomes smaller, but approximately the same analysis result can be generated, and the data processing efficiency of the maintenance early warning method of the card reader equipment can be improved.
The preprocessing of the historical record data of each card reading module can comprise data transformation of the historical record data of each card reading module, and the historical record data of each card reading module is more suitable for data mining through the data transformation. For example, the conversion of the geographical position information classifies the geographical position information, and the same category uses the same number to represent, so that the text data is converted into discrete numerical data.

specifically, after obtaining the prediction data of each card reading module, the server may perform feature processing on the prediction data of each card reading module to obtain the prediction feature data of each card reading module.
For example, characterizing the prediction data for each card reading module may include feature construction. The feature construction is used for constructing different types of features from the prediction data of each card reading module, the device features can be constructed based on the device data, the period features can be constructed based on the periodic data, the salary starting social security features can be constructed based on the salary sending and social security data, the holiday saving features can be constructed based on the holiday data, the use times statistical features can be constructed based on the use times statistical data, the use times in the same period can be constructed based on the use times in the same period, the use times in the later period can be constructed based on the use times in the later period, the average use features can be constructed based on the average use times data, and the use times in the ring ratio can be constructed based on the use times in the ring ratio.

specifically, after obtaining the predicted number of usage times of each card reading module, the server may further obtain the current accumulated number of usage times of each card reading module, where each card reading module is recorded during usage, and the current accumulated number of usage times of each card reading module may be obtained through statistics. For each card reading module, the server calculates the sum of the predicted use times and the current accumulated use times of the card reading module, and the sum result is used as the predicted accumulated use times of the card reading module. The current accumulated use times of the card reading module refers to the total use times of the card reading module from the beginning of use to the time of use prediction.
And S205, if the predicted accumulated use times of the card reading module are judged to be larger than the corresponding use threshold, sending second early warning information.
Specifically, after obtaining the predicted accumulated use times of each card reading module, the server compares the predicted accumulated use times of the card reading module with the use threshold corresponding to the card reading module for each card reading module, and if the predicted accumulated use times of the card reading module is greater than the use threshold corresponding to the card reading module, it is indicated that the card reading module is about to malfunction, the server may send second warning information, so that a worker can perform operation and maintenance preparation work. And if the predicted accumulated use times of the card reading module is less than or equal to the use threshold corresponding to the card reading module, the card reading module can still be used without maintenance. The use threshold corresponding to each card reading module is set according to actual conditions, and the embodiment of the invention is not limited. It can be understood that the predicted accumulated use times of any card reading module of the card reader device is greater than the corresponding use threshold, and maintenance early warning information can be sent out, wherein the maintenance early warning information can indicate the card reading module which needs to be maintained.
For example, the card reading module is a magnetic stripe type read-write module, which is expected to be able to be refreshed 2000 times, that is, the usage threshold corresponding to the magnetic stripe type read-write module is 2000 times, if the server obtains that the predicted usage number of the next magnetic stripe type read-write module is 300 times and obtains that the current accumulated usage number of the magnetic stripe type read-write module is 1800 times, the server calculates that the predicted accumulated usage number of the magnetic stripe type read-write module is 1800+300 times to 2100 times, because the predicted accumulated usage number 2100 of the magnetic stripe type read-write module is greater than the usage threshold 2000 corresponding to the magnetic stripe type read-write module, the server may send maintenance warning information, for example, to notify a worker in a manner of a mobile phone short message, and the magnetic stripe type read-write module may reach the usage.
