Technical Field
The invention relates to the field of subway traffic, in particular to a ticket checking system and a ticket checking method for a subway access passage.
Background
In the existing transportation field, a scheme of using a plurality of ticket checking modes in a mixed mode is often adopted. However, because the face recognition is a passive process, in the traditional mixed multiple ticket checking scheme, the adopted layout mode cannot accurately distinguish the ticket checking intentions of passengers, which easily causes that the faces of passengers who are swiping cards or performing two-dimensional code scanning are captured by a face recognition camera, so that the currently collected face images of passengers are not images capable of accurately identifying the identities of users, and therefore, the accuracy of the identification results of the ticket checking intentions of the users is seriously affected, thereby causing errors in ticket checking and charging of the subway and reducing the passing rate of the users in and out of the ticket checking channel. That is, the number of comparison times (RN) is greatly increased due to the existence of a large number of accidental captures, and the total number of Errors (ERN) of the user ticket checking intention recognition result is also greatly increased.
In addition, the existing face recognition algorithm cannot guarantee 100% accuracy, and the probability of recognizing two different user faces as the same person is generally measured by using a false recognition rate (FAR) index; the probability of two photos of the same user being recognized as not being the same person is measured by the rejection rate (FRR). The two indexes have relevance, and generally, the lower the FAR, the higher the FRR; on the contrary, the existing face recognition algorithm cannot provide a technical solution to make FAR equal to 0. Therefore, on the basis that the accuracy of the user ticket checking intention identification result caused by the fact that the face image is captured accidentally is reduced, the ticket checking intention identification result is further reduced due to the false identification rate of the face identification algorithm, and the error rate of charging when the subway ticket checking is carried out and the passing rate of the ticket checking passage are further influenced.

Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
Additionally, the steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
In the existing transportation field, a scheme of using a plurality of ticket checking modes in a mixed mode is often adopted. However, because the face recognition is a passive process, in the traditional mixed multiple ticket checking scheme, the adopted layout mode cannot accurately distinguish the ticket checking intentions of passengers, which easily causes that the faces of passengers who are swiping cards or performing two-dimensional code scanning are captured by a face recognition camera, so that the currently collected face images of passengers are not images capable of accurately identifying the identities of users, and therefore, the accuracy of the identification results of the ticket checking intentions of the users is seriously affected, thereby causing errors in ticket checking and charging of the subway and reducing the passing rate of the users in and out of the ticket checking channel. That is, the number of comparison times (RN) is greatly increased due to the existence of a large number of accidental captures, and the total number of Errors (ERN) of the user ticket checking intention recognition result is also greatly increased.
In addition, the existing face recognition algorithm cannot guarantee 100% accuracy, and the probability of recognizing two different user faces as the same person is generally measured by using a false recognition rate (FAR) index; the probability of two photos of the same user being recognized as not being the same person is measured by the rejection rate (FRR). The two indexes have relevance, and generally, the lower the FAR, the higher the FRR; on the contrary, the existing face recognition algorithm cannot provide a technical solution to make FAR equal to 0. Therefore, on the basis that the accuracy of the user ticket checking intention identification result caused by the fact that the face image is captured accidentally is reduced, the ticket checking intention identification result is further reduced due to the false identification rate of the face identification algorithm, and the error rate of charging when the subway ticket checking is carried out and the passing rate of the ticket checking passage are further influenced.
In order to solve the technical problem, the invention provides a ticket checking display screen with two different angles, which separates the passenger card swiping behavior and the passenger passage behavior, so as to avoid the situation of accidentally capturing the facial image. Furthermore, on the basis of avoiding the occurrence of accidental face image capturing, any one of various mixed ticket checking modes can be adopted, and the various ticket checking modes can be jointly used, so that each passenger can quickly and accurately pass through the access passage, the billing error rate is reduced, and the accuracy of the passenger ticket checking intention identification result and the passing rate of the passenger through the access passage are improved.
Fig. 1 is a schematic application environment diagram of a ticket checking system for a subway entrance/exit passage according to an embodiment of the present application. Fig. 2 is a schematic structural diagram of a ticket checking system for a subway entrance/exit passage according to an embodiment of the present application. The ticket checking system according to the present invention will be described in detail with reference to fig. 1 and 2.
As shown in fig. 1, the ticket checking system includes at least: the system comprises a channel ticket checking device 10, a face camera 20 and a comparison server 30. The channel ticket checking device 10 is disposed inside the channel cabinet housing, and is used as a local server to communicate with the comparison server 30, and is mainly used for identifying whether the current user has a ticket checking intention (an intention to enter or exit from a station) according to the facial image of the passenger captured by the face camera 20. Referring to fig. 1, a (rectangular parallelepiped) space region, which is an effective access duct, is formed between adjacent duct cabinets, and a specific detection region is provided inside the effective access duct and near an entrance. In the invention, the face camera 20 is installed above the effective access passage, so that the detection range of the face camera 20 can only capture the image of the passenger in the detection area, and the image of the passenger entering the effective access passage after the passenger swipes the card can be accurately obtained, and the image of the passenger in the external space of the effective access passage before the passenger swipes the card can not be detected. Thus, the face camera 20 is used to capture an image of the passenger's face as the passenger enters the detection zone. The passenger face image obtained at this time is an image that is captured with an intention of getting on and off the station at a large probability when the passenger enters the detection area when the passenger attempts to pass through the entrance/exit passage after the passenger swipes the card in the space outside the detection area.
Further, in the embodiment of the present invention, the face camera 20 is a camera with three-dimensional detection capability. Preferably the face camera 20 is selected from one of a TOF camera, an RGB binocular camera, a structured light based depth camera.
Further, the passageway ticket checking device 10 is configured to identify whether the current passenger has an intention to enter or exit from the passageway according to the currently acquired passenger face image, and transmit the face image data of the current passenger to the comparison server 30 when it is determined that the current passenger has the intention to enter or exit from the passageway. The comparison server 30 may be disposed in the subway station general control room, networked with the subway service system server, and may access the subway service system server to retrieve and/or edit the internal information of the passenger database at any time. The passenger database stores at least: the subway service system website registers user codes of all passengers, facial image information of each passenger, historical riding record information of each passenger (the historical riding record information comprises the user codes, the station entering position, the station entering time, the station exiting position, the station exiting time and the like), and billing record information of each passenger generated in real time based on the historical riding record of each passenger and the like.
Therefore, in the embodiment of the present invention, the comparison server 30 is configured to search the passenger database for the riding record information of the current passenger according to the acquired face image of the current passenger, update the riding record information of the passenger, generate an instruction (comparison passing instruction) indicating that the current comparison passes after the update is completed, and then send the current comparison passing instruction to the channel ticket checking device 10. When the riding record information of the current passenger is updated, information such as the arrival time and the arrival station position of the passenger needs to be written in the historical riding record of the current passenger. Further, the comparison server 30 is configured to update the charging record information of the current passenger after generating the comparison passing instruction and receiving the behavior signal.
In the present invention, the passage ticket checking device 10 further performs the following method in the process of identifying whether the passenger has the intention of entering or leaving the station: firstly, extracting facial features of an acquired passenger face image; according to the facial feature extraction result, respectively analyzing the face definition in the image, the proportion of the face size in the current image, the angle between the face front and the face camera 20, the distance (feature) data of the face relative to the face camera 20 and the shielding degree of the face by a shielding object to obtain corresponding feature data; and then, comparing each item of feature data with a corresponding preset feature threshold respectively, and determining that the current passenger has the intention of getting in and out when all comparison results reach the corresponding feature threshold. That is to say, when comparing the feature data, it is necessary to compare the face definition feature data with a preset definition threshold, compare the image proportion feature data occupied by the face with a preset proportion threshold, compare the face angle feature data with a preset angle threshold, compare the face shielding degree feature data with a preset shielding degree threshold, and when each feature data reaches or exceeds the corresponding threshold data, determine that the current passenger has the intention of entering or exiting the station.
In addition, when any one or more of the characteristic data does not reach the corresponding threshold standard, the passenger does not have the purpose of entering or exiting the station currently. At this time, the passage ticket gate 10 is configured to generate a warning signal indicating that the detection fails when it is determined that the present passenger does not have the intention to enter or exit the station.
The invention utilizes the setting position of the face camera 20 and the combination structure association of the channel ticket checking device 10, the face camera 20 and the comparison server 30 to avoid the unexpected capture of the passenger face image when the passenger swipes the card or scans the two-dimensional code, thereby improving the accuracy of the passenger intention identification result, reducing the error of the detected system passing rate and the actual situation and improving the passenger billing accuracy.
With continued reference to fig. 1, the ticket checking system of the present invention further includes: the device comprises a card swiping device 40, a first ticket checking display screen 51, a second ticket checking display screen 52 and a human body detection device 60. The card reader 40 is disposed on the outer casing at the entrance of the channel cabinet, and more specifically, the outer side of the channel cabinet refers to the space outside the effective access channel space. In this way, when the passenger conducts the card swiping behavior in the normal posture, the passenger is out of the detection range of the human face camera 20, and therefore the passenger face image when the card swiping behavior is conducted by the user is prevented from being accidentally captured.
Thus, the card swiping device 40 is used for reading the passenger card swiping information when the user does not enter the detection area (located outside the detection area), so that the card swiping information and/or the current face image are uploaded to the comparison server 30 by the passage ticket checking device 10 when the passenger has the purpose of entering or exiting the station. Wherein, referring to fig. 2, the card swiping device 40 comprises: a two-dimensional code module 41 and an RF card reading module 42. The two-dimensional code module 41 is connected with the channel ticket checking device 10 through an RS232 and is used for reading two-dimensional code data containing passenger identity information, so that the channel ticket checking device 10 can obtain card swiping information containing passenger identity information when a passenger swipes a card. The RF card reading module 42 includes an RF card reader 421 and a card reader antenna 422, the RF card reader 421 is connected to the channel ticket checking device 10 through RS232, and the RF card reader 421 is connected to the card reader antenna 422 through radio frequency. The RF card reading module 42 is used for reading a radio frequency signal containing passenger identity information, so that the passage ticket checking device 10 can obtain card swiping information containing passenger identity information when a passenger swipes a card.
In the practical application process, passengers can enter the effective access passage only by a two-dimensional code card swiping mode, an IC card swiping mode or a face recognition mode directly in a detection area without the card swiping mode, and in order to adapt to different modes when different passengers enter the passage, the invention provides various alternative station entering modes for the passengers entering the effective access passage in different modes by a scheme of mixing various card swiping devices and a face camera, so that each passenger can smoothly pass through the access passage in a respective convenient or customary mode and complete an accurate charging task.
When the passenger uses a two-dimensional code or an IC card to pass through an access passage and determines that the current passenger has the intention of getting in or out of the station, the card swiping information of the current passenger or the facial image of the current passenger can be uploaded to the comparison server, the riding record information of the current passenger is searched in the passenger database by using the corresponding uploading information, and the riding record is updated; the two kinds of information may also be uploaded to the comparison server 30, and any one of the two kinds of information is used to search the current passenger's riding record information and update the riding record.
Further, referring to fig. 1, a first ticket gate display screen 51 is disposed above the card swiping device 40, and is connected with the channel ticket gate device 10 through HDMI. The first ticket checking display screen 51 is used for displaying the card swiping information of the current passenger (after the passage ticket checking device 10 acquires the card swiping information of the passenger) so as to prompt that the card swiping of the current passenger is successful. The second ticket checking display screen 52 is disposed on the casing of the channel cabinet below the face camera 20, and is connected to the channel ticket checking device 10 via HDMI. The second ticket gate display screen 52 is used to display the face image of the current passenger (after the passage ticket gate 10 acquires the face image of the current passenger) to prompt that the image capture of the current passenger is successful. In addition, the first ticket checking display screen 51 is also used for responding to the comparison passing instruction received by the passage ticket checking device 10 and displaying the prompt information that the current passenger passes the comparison. Meanwhile, the second ticket checking display screen 52 is also used for responding to the comparison passing instruction received by the passage ticket checking device 10 and displaying the prompt message that the current passenger passes the comparison.
Further, the first ticket checking display screen 51 is also used for responding to the warning prompt signal generated by the passage ticket checking device 10 and displaying the prompt information that the current passenger fails to pass the comparison. Meanwhile, the second ticket checking display screen 52 is also used for responding to the warning prompt signal generated by the passage ticket checking device 10 and displaying the prompt information that the current passenger fails to pass the comparison. Thus, the present invention displays prompt information on whether the passenger can pass through the currently valid access passage in time through the first ticket checking display screen 51 and the second ticket checking display screen 52.
Further, after the passage ticket checking device 10 receives the comparison passing instruction, the passage ticket checking device 10 is further configured to generate an instruction for controlling the face camera 20 to stop capturing the face image of the current passenger after receiving the comparison passing instruction, so that the face camera 20 stops capturing the image state (face capturing state) under the action of the current instruction.
When the passenger knows that the passing comparison is known through the prompt of the first ticket checking display screen 51 and the second ticket checking display screen 52, if the passenger walks out of the detection area and approaches the exit, it indicates that the passenger currently passes through the effective access passage, so that in order to detect the behavior of passing through the effective access passage, a corresponding human body detection device 60 needs to be arranged in the effective access passage and near the middle part or the exit of the passage to detect the behavior of the passenger currently. Thus, the human body detecting device 60 is disposed in the lower inner side of the effective access duct, and more specifically, the device 60 is disposed on the cabinet housing of the duct below the middle portion of the effective access duct or below the exit. Wherein the human body detecting device 60 is selected from one of an infrared correlation sensor, an infrared proximity sensor, a microwave sensor, and a laser radar sensor.
The human body detection device 60 is connected to the passage ticket checking device 10, and is configured to output a signal (i.e., a behavior signal) indicating that the passenger has a behavior passing through the effective access passage when the passenger passes through the current effective access passage, so that the face camera 20 recovers a face capture state in response to the current behavior signal, and the comparison server 30 updates the billing information of the current passenger. Specifically, after the human body detection device 60 outputs the valid behavior signal, on one hand, when the channel ticket gate 10 obtains the currently valid behavior signal, the face camera 20 is configured to control itself to return to the face capturing state in response to the currently valid behavior signal. Since the passenger who has passed the comparison performs the action of passing through the effective access passage, the passenger has left the detection area and can trigger the human body detection device 60 to output an effective signal, when the face camera 20 recovers to the face capturing state, the current passenger has left the detection area of the camera 20, and the facial image captured again is the next passenger who wants to pass through the current effective access passage.
In addition, when the channel ticket checking device 10 obtains the currently valid behavior signal, the channel ticket checking device 10 is further configured to forward the currently valid behavior signal to the comparison server 30. At this time, the comparison server 30 is further configured to update the charging record information of the current passenger after receiving the valid behavior signal sent by the current channel ticket checking device 10. Therefore, the aim of accurately recording the passenger billing information is fulfilled.
Further, when the passage ticket checking apparatus 10 obtains the currently valid behavior signal, the first ticket checking display screen 51 is also used to restore the default display state in response to the currently valid behavior signal received by the passage ticket checking apparatus 10. Meanwhile, the second ticket gate display 52 is also used for responding to the currently valid behavior signal received by the passage ticket gate 10 to restore the default display state. In this way, by the restoration of the default states of the first ticket checking display screen 51 and the second ticket checking display screen 52, the card swiping information, the face image and the comparison result prompting information of the next passenger are waited to be displayed.
In addition, the passage ticket checking device 10 is further configured to count time after receiving the comparison passing instruction, and if the valid behavior signal output from the human body detection device 60 is not detected within a preset time period, control the first ticket checking display screen 51 and the second ticket checking display screen 52 to restore the default display state, and control the face camera 20 to restore the face capture state to wait for the next passenger. Therefore, in this way, the embodiment of the present invention prevents the first and second ticket checking display screens 51 and 52 from failing to display corresponding information to the next passenger and causing the face camera 20 to fail to quickly acquire the face image of the next passenger when the passenger does not enter the effective access passage even though the comparison is successful.
Therefore, the invention respectively completes the detection of the card swiping action, the identification of the station entrance intention and the effective access passage action for the same passenger, and improves the charging accuracy of the system and the passing rate of the passenger by mixing various ticket checking modes and the layout of the ticket checking system.
Finally, it should be noted that after the comparison server 30 completes updating the riding record information and the billing record information, a corresponding update notification or a corresponding reminder message is sent to the terminal device associated with the current passenger when registering in the subway service system website, so that the passenger can smoothly look up the riding record and the relevant billing information when visiting the subway service system website through the terminal device of the passenger. In addition, when the comparison server 30 searches the riding record information and/or the billing record information of the corresponding passenger in the passenger database according to the uploaded passenger face image or the card swiping information, if the relevant information of the current passenger is not searched, the comparison server feeds back prompt information indicating that the passenger is required to register in time to the passage ticket checking device 10, so that the first ticket checking display screen 51 and the second ticket checking display screen 52 display the current prompt information at the same time, thereby prompting that the current passenger cannot pass through the passage because of unregistered passenger.
With continued reference to fig. 2, the ticket checking system of the present invention further includes: an inspection camera 70, an auxiliary door leaf device 80 and an acoustic control device 90. Wherein, the inspection camera 70 is connected with the passage ticket checking device 10 and is used for recording the video data of the passenger moving near the passage cabinet. More specifically, the audit camera 70 is configured to activate when a passenger enters the checkbox and record video data of the current passenger activity in the vicinity of the current aisle cabinet. Thus, by providing the audit camera 70, the violation of the anomaly through the valid ingress and egress channels is captured.
Further, the auxiliary door device 80 includes: a main control panel 81, a door controller 82, a door 83, and an aisle indicator 84. The main control board 81 is connected to the channel ticket gate apparatus 10, and is configured to receive a door leaf state instruction sent by the channel ticket gate apparatus 10, and generate a signal for controlling the opening and closing state of the door leaf according to the door leaf state instruction. The door controller 82 is connected to the main control board 81 through RS232, and is configured to mechanically control a door opening and closing operation according to a door opening and closing signal, so that the door 83 completes a corresponding opening and closing operation. The channel indicator 84 is connected to the main control panel 81 and is responsive to a door opening and closing signal (e.g., the indicator 84 is on when a door opening and closing signal indicating a door opening state is received and the indicator 84 is off when a door opening and closing signal indicating a door closing state is received).
It should be noted that, in the practical application process, for the control of the auxiliary door leaf device 80, the subway is managed by adopting two modes, namely a normally open mode and a normally closed mode, and if the subway selects the normally open mode, the auxiliary door leaf device 80 can continuously receive the door leaf state instruction which is sent by the channel ticket checking device 10 and indicates that the door leaf state is kept in the door opening state, and no other setting is performed. In addition, the auxiliary door device 80 receives a door state command indicating a door closing state sent by the passage ticket gate 10 to control the door 83 to close in case of an emergency (for example, a special situation such as a pedestrian tailgating or a reverse gate break).
Further, the voice control device 90 includes a power amplifier 91 and a speaker 92. The sound control device 90 is used for responding to the comparison passing instruction so as to perform sound prompt when the current passenger passes the comparison and verification. In addition, the voice control device 90 is also used for responding to the above-mentioned warning prompt signal generated by the passage ticket checking device 10 to make a voice prompt. It should be noted that the voice control device 90 distinguishes two different situations by comparing the different meanings through the instruction and the corresponding different warning sounds of the warning prompt signal.
Further, the channel display screen 53 is disposed on the outer side of the middle portion of the channel cabinet and used for displaying the content of the notification of the subway service system, the notification of the subway platform, the propaganda information, the card swiping information of the passenger and the like.
Fig. 3 is a schematic workflow diagram of a system when a passenger uses a card swiping device to enter a station in the ticket checking system for the subway access passage according to the embodiment of the application. The ticket checking process of a passenger who enters the passageway in a card swiping manner will be described below with reference to fig. 3. Step S301, the passenger stands in front of the card swiping device 40 and swipes the card by adopting a two-dimensional code or an IC card, step S302, the channel ticket checking device 10 obtains the card swiping information of the current passenger, and then the step S303 is carried out. Step S303, after the current passenger finishes swiping the card, the current passenger enters the detection area and the face camera 20 in the face capture state captures the face image of the current passenger. Then, in step S304, the lane ticket gate apparatus 10 determines whether or not the present passenger has an intention to enter or exit from the station based on the face image of the passenger currently acquired, and if so, it proceeds to step S305. Step S305, the channel ticket checking device 10 transmits the face image and/or the card swiping information of the current passenger to the comparison server 30, step S306, the comparison server 30 searches the riding record information of the current passenger in the passenger database through the face image or the card swiping information of the current passenger, if the information of the current passenger is searched, step S307 updates the riding record information of the current passenger, step S308 generates a comparison passing instruction for the current passenger, and returns the instruction to the channel ticket checking device 10, thereby entering step S309. In addition, if the relevant record information of the current passenger is not searched in step S306, step S318 transmits the prompt information of please register to the passage ticket gate apparatus 10 so that all the ticket gate display screens display the current prompt information at the same time.
After receiving the comparison passing instruction, the channel ticket checking device 10 stops capturing the face image of the current passenger in step S309, and the first ticket checking display screen 51 and the second ticket checking display screen 52 simultaneously respond to the comparison passing instruction in step S310 to display the prompt information that the current passenger passes the comparison. Then, after receiving the comparison passing instruction, the channel ticket checking device 10 starts timing in step S311, and if an effective behavior signal indicating that the current passenger passes through an effective access channel is detected within a preset time period, the process goes to step S313; if no valid behavior signal indicating that the current passenger passes through the valid ingress/egress channel is detected within the preset time period, the process proceeds directly to step S314. In addition, after the current passenger sees the prompt information of passing the comparison, the human body detecting device 60 outputs an effective behavior signal triggered when the passenger passes the effective entrance/exit passage in step S312. Step S313 compares that the validity of the current passenger received by the server 30 through the passage ticket gate 10 is a signal, and based on this, updates the charging record information of the current passenger, thereby completing accurate charging for the current passenger, and then proceeds to step S314.
Next, the face camera 20 restores the face capturing state in response to the currently valid behavior signal received by the passage ticket gate apparatus 10 at step S314, and simultaneously, the first ticket gate display screen 51 and the second ticket gate display screen 52 restore the default state in response to the valid behavior signal at the same time at step S315. Therefore, whether the current passenger smoothly passes through the effective access passage or not, the information acquisition equipment in the ticket checking system is recovered to the state to be acquired so as to wait for the next passenger.
In the above step S304, when the passage ticket gate 10 detects that the present passenger does not have the intention to enter or exit, the process proceeds to step S316. Step S316, the channel ticket checking device 10 generates a warning prompt signal indicating that the detection fails, and in step S317, the first ticket checking display screen 51 and the second ticket checking display screen 52 simultaneously respond to the current warning prompt signal, and display a prompt message indicating that the comparison of the current passenger fails, so that the process proceeds to step S314, and the ticket checking program is executed again on the current passenger.
Fig. 4 is a schematic workflow diagram of a system when a passenger directly enters a station through a facial recognition mode in the ticket checking system for the subway entrance and exit passage according to the embodiment of the application. The ticket checking process of a passenger who enters the passageway in a card swiping manner will be described with reference to fig. 4. Step S401 the passenger enters the detection area and the face camera 20 in the face capture state captures the face image of the current passenger. Then, in step S402, the lane ticket gate apparatus 10 determines whether the current passenger has an intention to enter or exit from the station based on the currently acquired passenger face image, and if so, the process proceeds to step S403. The channel ticket checking device 10 transmits the face image of the current passenger to the comparison server 30 in step S403, the comparison server 30 searches the passenger database for the riding record information of the current passenger through the face image of the current passenger in step S404, if the information of the current passenger is found, the riding record information of the current passenger is updated in step S405, a comparison passing instruction for the current passenger is generated in step S406, and the instruction is transmitted back to the channel ticket checking device 10, so that the process proceeds to step S407. In addition, if the relevant record information of the current passenger is not searched in step S404, step S416 transmits the prompt information of please register to the passage ticket gate apparatus 10, so that all the ticket gate display screens display the current prompt information at the same time.
After receiving the comparison passing instruction, the passage ticket checking device 10 stops capturing the face image of the current passenger in step S407, and the first ticket checking display screen 51 and the second ticket checking display screen 52 simultaneously respond to the comparison passing instruction in step S408, and display the prompt information that the current passenger passes the comparison. Then, after receiving the comparison passing instruction, the passage ticket checking device 10 starts timing in step S409, and if an effective behavior signal indicating that the current passenger passes through an effective access passage is detected within a preset time period, the process goes to step S411; if no valid behavior signal indicating that the current passenger passes through the valid entry/exit lane is detected within the preset time period, the process proceeds directly to step S412. In addition, after the current passenger sees the prompt information of passing the comparison, the human body detecting device 60 outputs an effective behavior signal triggered when the passenger passes the effective entrance/exit passage in step S410. Step S411 compares that the validity of the current passenger received by the server 30 through the passage ticket checking device 10 is a signal, and updates the charging record information of the current passenger based on the signal, thereby completing accurate charging for the current passenger, and then the process proceeds to step S412.
Next, the face camera 20 restores the face capturing state in response to the currently valid behavior signal received by the passage ticket gate apparatus 10 at step S412, and simultaneously, the first ticket gate display screen 51 and the second ticket gate display screen 52 restore the default state in response to the valid behavior signal at the same time at step S413. Therefore, whether the current passenger smoothly passes through the effective access passage or not, the information acquisition equipment in the ticket checking system is recovered to the state to be acquired so as to wait for the next passenger.
In the above step S402, when the passage ticket gate 10 detects that the present passenger does not have the intention to enter or exit, the routine proceeds to step S414. The passage ticket checking device 10 generates a warning prompt signal indicating that the detection fails in step S414, and the first ticket checking display screen 51 and the second ticket checking display screen 52 simultaneously respond to the current warning prompt signal in step S415, and display a prompt message indicating that the comparison of the current passenger fails, so that the process proceeds to step S412, and the ticket checking program is executed again on the current passenger.
