For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

In the embodiment of the present invention, the "plurality" may mean at least two, for example, two, three, or more, and the embodiment of the present invention is not limited.

In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified.

Some terms referred to herein are explained below to facilitate understanding by those skilled in the art.

1. The bus code is a two-dimensional code used by a user to take a vehicle such as a bus or a subway, and the bus code contains information such as an identity (also called as a user identity), a payment mode, a timestamp (generation time of the bus code) and the like of the user. In addition, the riding code also comprises an expandable data area, and data can be written or modified in the expandable data area, so that the expansion application of the riding code is realized.

The ride codes may be refreshed periodically, for example, every 20 seconds or 10 seconds, and ride codes generated by different ride code clients may have different refresh periods. In addition, the bus codes can be distinguished from the use scene into inbound bus codes and outbound bus codes, for example, when taking a subway, the bus codes used when entering the station can be understood as inbound bus codes, and the bus codes used when exiting the station can be understood as outbound bus codes.

2. The riding code client is used by depending on the terminal device, specifically, the riding code is generated and displayed through the riding code client running in the terminal device, and the riding code client can be understood as an application client. In practice, the bus code client may be an independent Application (APP), such as a bus code client issued by a certain subway company or a certain public transport company and dedicated to use by taking a vehicle within the jurisdiction of the subway company or the public transport company, for example, heaven city expert, sheep city expert, and the like, or the bus code client may also be a functional module embedded in an existing APP, for example, the current payment treasures and the existing wechat both support the use of the bus code, so the payment treasures client and the wechat client may be understood as the aforementioned bus code client, and since the payment treasures and the wechat are relatively wide in use range and the user group is relatively large, the popularity of the corresponding bus code can be increased by carrying the bus code in this way.

Taking the wechat client as an example, the riding code function can be embedded in the wechat client in a small program mode, the traffic can be saved in the small program embedded mode, and the wechat client can run quickly, when a user needs to use the riding code, the riding code small program can be found through a pull-down wechat main interface or a searching mode, and then the user enters a running interface of the riding code small program, and then a display interface of the riding code can be called through some operations. Taking the terminal device as a mobile phone as an example, the mobile phone is installed with a riding code client, and after the riding code client is operated, a display interface of the riding code is shown in fig. 1.

3. A traffic code scanning device is a device for scanning a riding code, and may also be referred to as a code scanning device, a ticket checking machine, and the like in some cases. The traffic code scanning device can obtain the two-dimensional code image of the bus code in a code scanning mode, and the two-dimensional code image of the bus code needs to be obtained in a code scanning mode, so that a camera is arranged in the traffic code scanning device and is used for scanning the bus code displayed by a user to obtain the two-dimensional code image of the bus code. Because the bus code is displayed in the terminal device (such as a mobile phone) in a two-dimensional code image mode, when a user needs to take a certain vehicle through the bus code, the bus code can be called out in the mobile phone, and then the bus code displayed by the mobile phone is aligned to a camera of the traffic code scanning device, so that the traffic code scanning device obtains the two-dimensional code image of the bus code.

According to different use scenes of the bus codes, the traffic code scanning device can be divided into an inbound code scanning device and an outbound code scanning device, and by taking a subway as an example, the traffic code scanning device for scanning the inbound bus codes can be understood as the inbound code scanning device when entering the station, and the traffic code scanning device for scanning the outbound bus codes can be understood as the outbound code scanning device when exiting the station. In another traffic scenario, for example, a bus, because there is no obvious distinction between an arrival and an exit, there is only one traffic code scanning device on the bus, and thus this traffic code scanning device can be understood as both an arrival code scanning device and an exit code scanning device, i.e. at this time, the arrival code scanning device and the exit code scanning device are the same device. According to different traffic scenes, the traffic code scanning device may correspond to different devices, for example, in traffic scenes such as subways, Bus Rapid Transit (BRT), light rails and the like, the traffic code scanning device may be a gate (including an inbound gate and an outbound gate), or in traffic scenes such as buses and the like, the traffic code scanning device may be a code scanning tool (such as a code scanning gun) arranged on the buses.

In addition, in order to enable the system to be applicable to multiple modes of taking a bus, a Near Field Communication (NFC) function may be further integrated into the traffic code scanning device, a conventional physical bus card is inductively identified through an NFC sensing area, and a ticket drop-off port may be further provided to facilitate the recovery of temporary tickets, taking the traffic code scanning device as a gate in a subway as an example, one possible subway gate that has been put into use at present is shown in fig. 2, and a schematic diagram of a user scanning a taking code in a mobile phone by using a camera of the subway gate is shown in fig. 3.

4. The bus code image is a two-dimensional code image of the bus code, such as a two-dimensional code image of the bus code generated and displayed in the mobile phone, and a two-dimensional code image obtained by scanning the bus code displayed in the mobile phone through a camera by the traffic code scanning device.

5. The duplication of the ride code is to be used by the user after the ride code of the user is duplicated, for example, the ride code in the mobile phone of the user of the third party is duplicated and then used by the user of the fourth party, where the duplication may include multiple implementation manners, and continuing the example that the ride code of the third party is duplicated and used by the fourth party, the duplication may refer to that the ride code of the third party is photographed by the third party or that a screenshot is sent to the fourth party, that is, the ride code is actively duplicated and sent to other users by an actual user of the ride code (that is, the third party) and used by other users, for example, this manner may be called as active duplication and use, or may also refer to that the ride code of the third party is photographed by the fourth party and used, for example, the ride code of the third party is secretly photographed by the fourth party and used, for example, this manner may be called as passive duplication and use, and so on the whole, the duplication and use of the ride code may be understood as being used by other users, rather than the actual user of the ride code.

According to the difference of the using places of the bus codes after being copied, the bus code copying and using can be divided into cross-station copying and using and co-station copying and using, wherein the cross-station copying and using means that users using the copied bus codes and actual users using the bus codes are located at different sites currently, namely different positions of the cross-station, and according to the same understanding, the co-station copying and using means that the users using the copied bus codes and the actual users using the bus codes are located at the same site currently. Continuing with the foregoing example, please refer to the schematic diagram of the subway line including multiple stations shown in fig. 4, and it can be seen that the subway line includes 5 subway stations, namely, station a, station B, station C, station D, and station E, assuming that zhang is at station a at this time and sends its riding code to lie quan for use after taking a picture, if lie quan is at another station (e.g., station F) different from station a at this time, the riding code is copied across stations for use, and if lie is also at station a at this time, the riding code is copied at the same station for use.

6. The broadcast device refers to a device with broadcast capability, and may broadcast and transmit information through a certain communication mechanism. According to different communication mechanisms, the range in which information broadcasted by different broadcasting devices can be transmitted is different, that is, different broadcasting devices may have different broadcasting ranges, and in the embodiment of the present invention, the range in which the broadcast information of a broadcasting device can be transmitted is referred to as an effective broadcasting range of the broadcasting device, as long as devices located within the effective broadcasting range can detect the broadcast information broadcasted by the broadcasting device.

7. The iBeacon device, which may also be referred to as an iBeacon base station, refers to a device that can broadcast information through the iBeacon technology, wherein the iBeacon technology is an accurate micro-positioning technology based on Bluetooth Low Energy (BLE) technology, which is introduced by apple in the world developer conference (WWDC) in 2013, and BLE is also known as Bluetooth 4.0 or Bluetooth Smart. The iBeacon base station may create a signal area, and when other devices enter the signal area, the signal network in the signal area may be accessed, so as to detect all information broadcast by the iBeacon base station, and the signal area created by the iBeacon base station may be understood as an effective broadcast range of the iBeacon base station, that is, the iBeacon device broadcasts information based on BLE technology.

The iBeacon device has an iBeacon Identifier, which may include a Universal Unique Identifier (UUID), a Major ID, and a Minor ID. The UUID can be understood as an identification number of a manufacturer of the iBeacon equipment; the Major ID is equivalent to a group number, namely all iBeacon devices in the same group have the same Major ID; the Minor ID is equivalent to identifying the individual iBeacon devices in the group. In general, the iBeacon identifier of the iBeacon device can uniquely represent the iBeacon device, that is, the iBeacon identifier has uniqueness.

8. A user identification is an identification that uniquely identifies a user, such as a virtual card number, a user nickname, or a set of random strings, among others.

As mentioned above, the car code may be copied during the use process, so that the car code may be used in an irregular manner, and in some cases, the car code may also cause property loss of the user or a public transportation operation company (e.g., a public transportation operation company or a subway operation company).

Please refer to a schematic diagram of two users (zhang san and lie san) respectively riding a subway by using respective riding codes shown in fig. 5, it can be known from fig. 5 that zhang san enters the station by using the own inbound riding code at station a and exits the station by using the own outbound riding code at station D, lie san enters the station by using the own riding code at station E and exits the station by using the own outbound riding code at station B, since zhang san enters the station (station a) and exits the station (station D) both use the own riding code and lie san four enters the station (station E) and exits the station (station B) both use the own riding code, the subway background server matches the travel for the users according to the riding codes, the travel of zhang matched by the subway background server is "station a-station D" and the travel of lie si matched by "station E-station B", this is consistent with the actual stroke of zhang san and lie san.

Referring to fig. 6, it can be seen that zhang san enters the station a using the own inbound bus code, and leaves the station D using the outbound bus code of lie si, and lie si enters the station E using the own inbound bus code, and leaves the station B using the outbound bus code of zhang san, and during the process of copying, zhang san and lie si can take a picture of their own bus code or capture a picture of their own bus code and send it to the other side for use after entering the station. Since the subway background server matches the travel for the user according to the riding code, the travel matched by the subway background server for Zhang-Sanqi is station A-station B, and the travel matched by Liqu is station E-station D, which is inconsistent with the actual travel of the user shown in FIG. 5, thereby causing a travel matching error. As can be seen from the analysis, for zhang san, the number of stations included in the trip is less for the trip "station a-station B" matched by the subway background server, compared with the actual trip "station a-station D" of zhang san, and then the number of natural trips is also shorter, and no matter in the subway charging mode in which the charging is performed according to the number of stations or the number of trips, the last fee deducted by zhang san is less than or equal to the fee deducted corresponding to the actual trip, and similarly, the fee deducted by lie is also the same, that is, zhang san and lie are used for achieving the purpose of reducing the traffic fee by mutually copying the riding codes of the other party, so that the charging of the subway operation company is reduced, economic loss is caused, the riding codes are not used in a standard manner, and the income of the traffic operation department is reduced.

Referring to fig. 7, a schematic diagram that two users (zhang san and wang wu) get in the subway from the same subway station is shown, zhang san and wang wu both get in from station a, suppose that zhang san uses their own inbound bus code, and wang wu quickly follows zhang san when zhang su passes through the inbound gate and gets in through the inbound gate, that is, wang wu does not use its own bus code, but arrives in a ticket-evading manner, after arriving, wang wu obtains the image of zhang san by some means (for example, by secretly shooting zhang san bus code), and then goes out by using zhang san bus code, and zhang san is still taken in the subway at this time, as shown in fig. 7, suppose wang wu gets out at station C using zhang bus code of zhang and then arrives at station C, and after going out at station C, it determines a trip of zhang san for the server, namely 'site A-site C', the trip of site A-site C is actually king five, but the final fee deduction is deduction Zhang three, so that the king five realizes the embezzlement of the bus code by copying and using the bus code of Zhang three, the trip fee generated by the ticket evasion behavior of king five is paid by Zhang three, the property loss of Zhang three is caused, the user is not good in use experience, and extra maintenance expenses such as complaints and refunds of passengers can be caused.

Through analysis of the prior art, the inventor of the present invention finds that adverse consequences caused by the duplication and use of the vehicle code in the prior art are serious, so that the duplication and use of the vehicle code needs to be detected, and then corresponding measures are taken to weaken or even avoid negative effects caused by the duplication and use of the vehicle code, however, a related technical scheme for detecting the duplication and use of the vehicle code does not exist at present. In view of the discovery and consideration of the foregoing technical problems, the inventor considers that the detection of the duplication of the riding code can be achieved in some way, and in view of the above, the inventor considers the characteristics of the duplication of the riding code, that is, the ultimate duplication of the riding code can be achieved only by the duplication, so that the possibility of the duplication of the riding code can be reduced or even eliminated from the source in some way, and further, the inventor considers that the generation of the riding code and the use can be bound by the same place, specifically, the place where the riding code is generated and the place where the riding code is used are ensured to be approximately the same by some way (for example, in the same site or in a certain area in a site), because the generation and the use of the riding code are performed at different sites for the duplication of the riding code in general, for example, as shown in fig. 5, when the ride code for the third dispatch to exit at the station D, that is, the ride code for the third dispatch to exit at the station D is generated at the station D, but the ride code for the third dispatch to exit at the station B is used by li four, it is obvious that the generation place (that is, the station D) and the use place (that is, the station B) of the ride code for the third dispatch to exit are different, so that the generation and the use of the ride code are prevented as much as possible from being duplicated and used at different places, and the detection of the duplication and use of the ride code is realized.

According to the analysis and consideration, the inventor designs a method for binding the terminal device (i.e., the device for bearing the riding code) and the traffic code scanning device (e.g., an inbound gate or an outbound gate) in the geographical position by broadcasting information within a certain range of a station, so that both the terminal device and the traffic code scanning device within the certain range can obtain the broadcast information at the same time, and perform mutual verification through predetermined verification information carried in the broadcast information, thereby judging whether the currently displayed riding code to be used in the terminal device is generated in the vicinity of the traffic code scanning device, and thus realizing the related detection of the copy and use of the riding code.

After the design idea of the embodiment of the present invention is introduced, some simple descriptions are provided below for application scenarios to which the technical solution of the embodiment of the present invention can be applied, and it should be noted that the application scenarios described below are only used for illustrating the embodiment of the present invention and are not limited. In specific implementation, the technical scheme provided by the embodiment of the invention can be flexibly applied according to actual needs.

Referring to fig. 8A, fig. 8A is an application scenario to which the technical solution in the embodiment of the present invention can be applied, and the application scenario shown in fig. 8A is an example of a scenario in which a subway is taken by a bus yard (or other scenarios clearly distinguished between an inbound and an outbound, such as an application scenario in which a BRT or a light rail is taken), where the application scenario includes a terminal device 81, a gate 82, a broadcasting device 83, an application server 84, and a subway backend server 85. The terminal device 81 is a device capable of operating a riding code client, and as described above, for example, a pay bank client or a wechat client may be operated, and the riding code may be directly used in the pay bank client or the wechat client, and since the riding code client is operated in the terminal device 81, an application server 84 is provided corresponding to the riding code client. The gate 82 may be an inbound gate or an outbound gate, that is, the technical solution in the embodiment of the present invention may be applied to detection of inbound bus code copy use, or detection of outbound bus code copy use, the gate 82 may scan a bus code generated and displayed by the terminal device 81 to obtain a bus code image, further may analyze the scanned bus code image to determine whether the currently scanned bus code is the bus code that is copy use, and may obtain a scan code record according to an analysis result of the bus code image, and then send the scan code record to the subway backend server 85 through the network, further, the subway backend server 85 may determine a user's travel according to the received scan code record, and may charge and deduct a fee for the determined travel after determining the travel, to realize the collection of the traffic fee. In addition, the gate 82 may further include a passage blocking device such as a gate leaf door, a gate swing door, or the like, which may be prohibited from opening to block the user from passing through the gate when it is determined that the riding code is duplicated, and may be opened to allow the user to enter or exit through the passage blocking device when it is determined that the riding code is not duplicated.

And, the broadcasting device 83 in fig. 8A refers to a device capable of broadcasting information by a broadcasting method, the information broadcasted by the broadcasting device 83 can be transmitted within a predetermined range, and the predetermined range is, for example, referred to as an effective broadcasting range of the broadcasting device 83, different types of broadcasting devices 83 may have different effective broadcasting ranges according to different communication methods and device performances, for example, the broadcasting device 83 is an iBeacon device that broadcasts information by a BLE technology, the corresponding effective broadcasting range may be, for example, several meters, and the like, and the power consumption of the broadcasting device 83 may be reduced as much as possible by broadcasting information by the BLE technology. The broadcast device 83 and the gate 82 may have a predetermined positional relationship such that the gate 82 is always within the effective broadcast range of the broadcast device 83 to obtain all broadcast information broadcast by the broadcast device 83, for example, the broadcast device 83 may be disposed at a position beside (e.g., 10 cm) the gate 82, or the broadcast device 83 may be disposed directly next to the gate 82, or the broadcast device 83 may be disposed directly within the housing of the gate 82, or the like, and the position of the broadcast device 83 may be fixed to avoid as much change in the effective broadcast range of the broadcast device 83 as possible. In addition, the broadcasting apparatus 83 may broadcast a plurality of pieces of broadcast information at a predetermined period, and the predetermined period may be adjusted according to different scenes, i.e., the broadcasting apparatus 83 may have an adjustable broadcasting period.

The method can be executed in sequence or in parallel according to the method shown in the embodiment or the figures when the method is executed in an actual processing procedure or a device (for example, a parallel processor or an application environment of multi-thread processing).

Referring to fig. 12, an embodiment of the present invention provides a detection system for vehicle code duplication, where the detection system for vehicle code duplication includes a terminal device, a broadcasting device, a traffic code scanning device, and may further include a server. The terminal device may be the aforementioned terminal device 81, terminal device 91, terminal device 101, or terminal device 102, the broadcasting device may be the aforementioned broadcasting device 83 or broadcasting device 103, the traffic code scanning device may be the aforementioned gate 82, gate 92, bus code scanning device 102, or bus code scanning device 112, and the server may be the aforementioned subway backend server 85, subway backend server 94, bus backend server 105, or bus backend server 114, it should be understood that, when the traffic code scanning device is a device with broadcasting capability (for example, the gate 92 or the bus code scanning device 112), the detection system for bus code duplication at this time may not include the broadcasting device any more, that is, it may be understood that the broadcasting device and the traffic code scanning device are integrated into one device, and then the detection system for bus code duplication at this time is shown in fig. 13.

Specifically, the detection system for use in copying the riding code in the embodiment of the present invention may be, for example, a system composed of all the devices included in any application scenario in fig. 8A to 8C and fig. 9 to 11, which is not described herein any more.

For convenience of understanding, the technical solution in the embodiment of the present invention is described below by taking as an example a traffic scene (for example, an application scene shown in fig. 8C) in which a traffic code scanning device and a broadcasting device are separately provided and a subway is taken by a car.

The following describes a technical solution in an embodiment of the present invention with reference to an interaction diagram of a detection method for duplication of a ride code in an embodiment of the present invention shown in fig. 14.

Step 1401: the broadcasting equipment broadcasts the broadcast information carrying the preset verification information.

In the specific implementation process, the broadcasting equipment can continuously broadcast information according to a preset period, for example, the information is broadcast once every 20 seconds, so that the power consumption can be reduced as much as possible, because a broadcasting mode is adopted, as long as the equipment in the effective broadcasting range of the broadcasting equipment can detect the information broadcast by the broadcasting equipment, in the embodiment of the invention, the positions of the traffic code scanning equipment and the broadcasting equipment are set to be a preset position relation, so that the traffic code scanning equipment can be ensured to be in the effective broadcasting range of the broadcasting equipment, so that all the broadcasting information broadcast by the broadcasting equipment can be received, taking a subway scene as an example, one broadcasting equipment can be arranged at each exit and each entrance of a subway station, and for each broadcasting equipment, the effective broadcasting range can cover all subway gates (entrance gates or exit gates) at the corresponding exit or entrance, or, a broadcasting device may be provided in one subway station, so that the effective broadcasting range of the broadcasting device may cover all gates in the whole subway station.

The predetermined authentication information in the embodiment of the present invention may be a device identifier of the broadcasting device, or may be other authentication information obtained based on the device identifier of the broadcasting device, where the device identifier of the broadcasting device has uniqueness. For example, assuming that the device id of the broadcasting device is 9sd65y, the predetermined authentication information may be 9sd65y, which is the same as the device id of the broadcasting device, or other authentication information may be obtained based on 9sd65y, in one possible embodiment, unique predetermined authentication information may be generated based on the device identification and the current generation time, for example, 9sd65y20180626153327, wherein 20180626153327 is the current generation time, that is, it indicates that 9sd65y20180626153327 is generated at 33 minutes and 27 seconds at 26, 15 and 6 months in 2018, alternatively, the predetermined verification information may be generated according to a combination of the device identifier and the current site identifier, the current geographical location information, or other random character strings, etc., in a manner similar to the manner described above according to the current generation time, and the description is not repeated here.

In this embodiment of the present invention, the broadcasting device refers to a device with a broadcasting capability, for example, the device may be an iBeacon device that broadcasts information by using a BLE technology, and the device identifier of the broadcasting device may be an iBeacon identifier of the iBeacon device at this time, or may be another type of device that broadcasts information by using another communication technology, which is not limited herein.

Step 1402: the traffic code scanning device obtains broadcast information carrying predetermined verification information.

Since the traffic code scanning device is within the effective broadcasting range of the broadcasting device, the traffic code scanning device can obtain the broadcasting information after the broadcasting information is broadcasted by the broadcasting device.

Step 1403: after the traffic code scanning device obtains the broadcast information, the traffic code scanning device can obtain the preset verification information in the broadcast information, and then generates the reference verification information according to the obtained preset verification information.

In one possible implementation, the traffic code scanning device may directly use the obtained predetermined verification information as the reference verification information, that is, the reference verification information and the predetermined verification information are substantially the same.

In another possible implementation, the traffic code scanning device may further perform predetermined processing on the obtained predetermined verification information according to a predetermined processing rule, so as to obtain the reference verification information. The predetermined processing rule in the embodiment of the present invention may be, for example, adding the current time to the predetermined verification information to obtain the reference verification information, or adding a specified character or number to one or more positions of the predetermined verification information, or adding the device identifier of the traffic code scanning device to the predetermined verification information to obtain the reference verification information.

Step 1404: the terminal equipment receives broadcast information carrying predetermined verification information.

Since the terminal device can receive the broadcast information broadcast by the broadcasting device, the terminal device is also necessarily within the effective broadcast range of the broadcasting device, for example, when a passenger needs to enter a subway station to take a subway, the passenger firstly needs to pass through an entrance gate (i.e. a traffic code scanning device), and then the passenger approaches the entrance gate, so that the passenger can naturally be within the effective broadcast range of the broadcasting device, and further obtain the broadcast information broadcast by the broadcasting device.

Step 1405: and the terminal equipment generates the riding code according to the preset verification information in the broadcast information.

That is, once the terminal device receives the broadcast information, it considers that the user has arrived near a certain station, which indicates that the user needs to enter or exit the station by using the bus code, so the terminal device can dynamically generate the bus code in time according to the predetermined verification information.

After the riding code is generated, the terminal device may directly display the newly generated riding code on a display screen of the terminal device so that the user can use the riding code immediately, or, in practice, as described above, if the user wishes to exchange the riding code with other users to achieve the purpose of saving riding cost, the generated riding code may be copied by capturing a picture or taking a picture, and the copied image of the riding code is sent to other users.

In addition, when the terminal device generates the riding code based on the predetermined verification information, the predetermined verification information may be directly added to the riding code, or the predetermined verification information may be processed first and then the processed predetermined verification information may be added to the riding code, as to whether to perform processing and how to perform processing when processing is required, corresponding implementation may be performed according to preset conditions agreed in advance between the terminal device and the traffic code scanning device, that is, the terminal device (specifically, a riding code client running in the terminal device) and the traffic code scanning device may establish preset conditions in advance between for judging the predetermined verification information, so that the terminal device may adopt an appropriate processing manner when generating the riding code and when the traffic code scanning device verifies the riding code.

Step 1406: and the terminal equipment displays the riding code to be used.

In the embodiment of the invention, the riding code to be used can be understood as the riding code which is currently used, for example, the user can get in or out of the station through the brake immediately, and the riding code which is about to be used by the user can be called the riding code to be used.

In practice, the to-be-used riding code displayed by the terminal device may be a newly generated riding code just based on the predetermined verification information in step 1405, or the to-be-used riding code may also be a duplicate image of a riding code generated by other users at other sites through other terminal devices by using other predetermined verification information in the broadcast information broadcast by the broadcast device at the other sites, that is, the to-be-used riding code currently displayed by the user may be a riding code of the user or a riding code duplicated and used by other users, and the purpose of the embodiment of the present invention is to detect whether the to-be-used riding code currently displayed by the user is duplicated and used.

It should be noted that, the order of executing step 1402+ step 1403 and step 1404+ step 1405 is not limited, and in practice, for example, step 1402 and step 1403 may be executed first, and then step 1404 and step 1405 may be executed, or step 1404 and step 1405 may be executed first, then step 1402 and step 1403 may be executed, or they may be executed simultaneously.

Step 1407: the traffic code scanning device scans the riding codes to be used displayed by the terminal device, and then the riding code images of the riding codes to be used can be obtained.

When a user needs to enter a station or leave the station, the to-be-used bus code displayed in the terminal equipment can be aligned to the camera of the traffic code scanning equipment, so that the traffic code scanning equipment can obtain a two-dimensional code image of the to-be-used bus code in a scanning mode, and a bus code image of the to-be-used bus code is obtained.

Step 1408: the traffic code scanning device analyzes the obtained riding code image, and further can obtain the verification information contained in the riding code image. For convenience of description, in the embodiment of the present invention, the verification information in the riding code to be used is referred to as to-be-detected verification information.

Step 1409: the traffic code scanning device judges whether the verification information to be detected and the reference verification information meet preset conditions.

After obtaining the verification information to be detected in the vehicle code to be used, further detecting whether the vehicle code to be used is copied and used according to preset conditions, specifically, the obtained verification information to be detected and the previously obtained reference verification information are matched and compared according to the preset conditions, for example, if the obtained verification information to be detected and the previously obtained reference verification information are consistent, it can be determined that the preset conditions are met, for example, if the obtained verification information to be detected and the previously obtained reference verification information are consistent with a preset matching rule, it can also be determined that the preset conditions are met, for example, if the obtained verification information to be detected is 9sd65y, and the obtained verification information to be detected is 9sd65y and the reference verification information 9sd65y20180627103928, it can be considered that the obtained verification information to be detected and the previously obtained reference verification information are.

Step 1410: and if the verification information to be detected and the reference verification information are determined not to meet the preset conditions, the traffic code scanning device determines that the to-be-used riding code displayed in the terminal device is the copied riding code.

Step 1411: and if the verification information to be detected and the reference verification information meet the preset conditions, the traffic code scanning device determines that the to-be-used riding code displayed in the terminal device is the normally-used riding code.

In the embodiment of the invention, since the bus code which is not copied and used is dynamically generated in real time according to the broadcast information near the current position of the terminal device, since the broadcast information can be obtained to indicate that the terminal device (namely, the user) is in a certain range (for example, the vicinity) of the broadcast device, the reference verification information is also generated according to the broadcast information to indicate that the traffic code scanning device is also in a certain range (for example, the vicinity or the complete approach) of the broadcast device, the method can naturally indicate that the distance between the terminal device and the traffic code scanning device is close, namely, the user needs to use the bus code to enter or exit through the traffic code scanning device, and the relative position between the terminal device and the traffic code scanning device is limited in a broadcast information mode, so that the situation that the bus code is copied and used can be avoided, and the current use can be detected in a preset condition judgment mode through the verification information to be detected and the reference verification information Whether the riding code is the riding code which is copied for use or not is achieved, and effective detection of copying and using of the riding code is achieved.

It can be understood that, since the broadcast information has a certain effective broadcast range, the generation location and the use location of the bus code are bound by the broadcast information, and if the bus code used in the effective broadcast range is not generated in the effective broadcast range, it can be shown that the currently used bus code is the bus code used in duplicate, that is, the embodiment of the present invention realizes effective detection of the duplicate use of the bus code by the predetermined verification information in the broadcast information, and further can standardize the use of the bus code.

Continuing with the foregoing example of fig. 6, when zhang prepares for outbound at station D using the outbound riding code of lie four, zhang aligns the riding code to be used (i.e., the riding code duplicate image of lie four) with the outbound gateway of station D, and the outbound gateway scans to obtain the verification information to be detected in the riding code to be used, which is obtained from the verification information (e.g., referred to as first verification information) carried in the broadcast information (e.g., first broadcast information) broadcast by the broadcasting equipment at station B because the riding code to be used is generated by lie four using a mobile phone at station B, and the reference verification information obtained in advance in the outbound gateway is determined from the verification information (e.g., referred to as second verification information) carried in the broadcast information (e.g., referred to as second broadcast information) broadcast by the broadcasting equipment at station D, and since the verification information carried in the broadcast information of the broadcasting equipment at different places is unique, when the gate compares the obtained verification information to be detected with the reference verification information, the gate finds that the verification information to be detected and the reference verification information do not meet the preset condition, and then determines that the bus code to be used at this time is the bus code which is duplicated to be used at this time.

Further, the following describes the technical solution in the embodiment of the present invention with reference to fig. 15.

Step 1501: after the broadcast information broadcasted by the broadcasting device is obtained in the manner described above, the terminal device may generate the riding code according to the predetermined verification information, the user identifier, and the geographic location information of the current location of the terminal device in the broadcast information.

That is to say, compared with the way of generating the car code by the terminal device shown in fig. 14, in the embodiment of the present invention, the terminal device also adds the user identifier and the geographic location information to the car code when generating the car code, of course, in the specific implementation process, only one of the user identifier or the geographic location information may be added to the car code along with the predetermined verification information, and the specific selection of which information is added to the car code along with the predetermined verification information may be determined according to specific service requirements.

Step 1502: after the ride code is generated in step 1501, the terminal device may copy the newly generated image of the ride code, and further transmit the generated copy image of the ride code to another terminal device, and then the other terminal device may obtain the generated copy image of the ride code.

Step 1503: and the terminal equipment displays the riding code to be used.

Similarly to the aforementioned step 1406, the to-be-used riding code currently displayed by the terminal device may be the newly generated riding code in the manner of step 1501, or may also be a received copied riding code image sent by another terminal device.

It should be noted that step 1502 is not an essential step, for example, if the terminal device displays the car code generated in step 1501 in step 1503, then step 1502 may not be executed without transmitting the copy image of the generated car code to another terminal device.

Step 1504: the traffic code scanning device scans the riding codes to be used displayed by the terminal device to obtain riding code images.

Step 1505: and the traffic code scanning equipment determines to-be-detected verification information, user identification and geographical position information in the to-be-used riding code according to the obtained riding code image.

It should be noted that, if the terminal device adds only one of the user identifier and the geographic location information to the vehicle code along with the predetermined verification information when generating the vehicle code, the traffic code scanning device can only parse the vehicle code to obtain one of the user identifier and the geographic location information.

Step 1506: the traffic code scanning device judges whether the verification information to be detected and the reference verification information meet preset conditions.

Step 1506 can be understood with reference to the description of step 1409, which is not repeated here.

Step 1507: if the verification information to be detected and the reference verification information do not meet the preset condition, the traffic code scanning device can further compare the obtained geographic position information with the geographic position information of the current position of the traffic code scanning device, and further obtain the position deviation of the two.

Step 1508: and if the position deviation is determined to be larger than the preset position deviation, determining that the riding code to be used is a riding code which is copied and used in a cross-station mode. The predetermined position deviation may be set according to actual settings, because generally, the actual distance between two sites is larger than the maximum distance within one site coverage, and thus the predetermined position deviation may be set as the maximum distance within one site coverage.

Step 1509: and if the position deviation is smaller than the preset position deviation, determining that the riding code to be used is a riding code copied and used in the same station.

According to the mode of the steps 1506 to 1509, the embodiment of the invention can accurately judge the type of the bus code copy use according to the geographical position information, that is, on the basis of determining that the bus code to be used is the copy use after judging the verification information to be detected and the reference verification information and the preset conditions, the method can further judge whether the copy use is the cross-station copy use or the same-station copy use on the basis of the geographical position information carried in the bus code, so as to carry out more detailed detection on the copy use of the bus code, and further improve the validity and the accuracy of the copy use detection.

Step 1510: if the verification information to be detected and the reference verification information do not meet the preset conditions, the traffic code scanning device can also output alarm information, the passenger code copying is prompted through the alarm information, the output mode of the alarm information can be audio, alarm music, light, images and the like, and the traffic code scanning device is not limited to the above mode, can warn the user who copies and uses the passenger code at present through the alarm information, and can prompt staff at a station to intervene in manual maintenance.

Step 1511: if the verification information to be detected and the reference verification information are determined not to meet the preset conditions, the traffic code scanning device can also generate riding code copying use prompt information, the riding code copying use prompt information is used for indicating that the currently used riding code is the copied riding code, and the riding code copying use prompt information can be written back to the terminal device through a near field communication mode (such as NFC or Bluetooth) so as to prompt a user.

Step 1512: if the verification information to be detected and the reference verification information meet the preset conditions, the traffic code scanning device determines that the riding code to be used is the riding code which is normally used, namely the detection is passed, and at the moment, a passing permission instruction can be sent to the passing blocking device to indicate that the passing blocking device is opened and then released. In a specific implementation process, the traffic blocking device may be an integrated device with the traffic code scanning device, or may be a separate device for blocking traffic, which is not limited in this embodiment of the present invention.

Step 1513: if it is determined that the verification information to be detected and the reference verification information do not meet the preset conditions, the traffic code scanning device can also generate a riding code copying use record, the riding code copying use record can include information such as copying use time and place, and the riding code copying use record and the user identifier are sent to a server (such as a background subway background server) together, so that the server can count the riding code abnormal use record of the user corresponding to the user identifier according to the received riding code copying use record, and recording and maintaining of the riding records of a plurality of users are achieved.

In addition, if the verification information to be detected and the reference verification information meet the preset conditions, the traffic code scanning device determines that the bus code to be used is the bus code which is normally used, at the moment, the code scanning time for scanning the bus code to be used can be obtained, a code scanning record is generated according to the code scanning time, the user identification and the information to be detected, and the generated code scanning record is sent to the server, so that the server can determine the traffic route of the user corresponding to the user identification according to the obtained plurality of code scanning records, further the server can charge and deduct the fee according to the determined traffic route, and the intelligent traffic of 'bus taking before and paying after' is realized.

The foregoing is described with reference to fig. 14 and 15 that the broadcasting device and the traffic code scanning device are two separate devices, and in the case that the broadcasting device and the traffic code scanning device are the same device, the difference is that the traffic code scanning device obtains the predetermined verification information from the broadcast information broadcasted by itself, and can generate the reference verification information based on the obtained predetermined verification information, and for other implementations, reference may be made to the implementations of fig. 14-15, and the description will not be repeated here.
