Detailed Description

Embodiments and examples of a gate system and a gate system control method according to the present invention are described below with reference to the drawings.

< first embodiment >

First, a brief configuration of the gate system according to the first embodiment will be described.

In the present invention, "front", "rear", "left" and "right" are front, rear, left and right directions when facing the inlet side of the gate system. "front" refers to the inlet side of the gate system and "rear" refers to the outlet side of the gate system. That is, the front-rear direction is a direction in which a passer-by passes through the gate system, and the direction of passing first is set as the front, and the direction of passing later is set as the rear. "left" is the left hand side of a passer-by through the gate system and "right" is the right hand side of a passer-by through the gate system.

Fig. 1 is a schematic diagram showing a schematic configuration of a gate system according to a first embodiment of the present invention. Fig. 2 is a schematic diagram showing functional modules of a gate system according to a first embodiment of the present invention.

As shown in FIGS. 1-2, the gate system 100 includes: a gate case 1, a gate 2, and a control device 40. Specifically, a gate 2 is installed on the gate casing 1. The gate casing 1 may include two gate casings respectively located at left and right sides of the gate 2. The control device 40 controls the opening and closing of the shutter 2. By default, the gate 2 is in a closed state.

As shown in fig. 1-2, the gate system 100 further includes: an access voucher information acquisition device 13 and a hazardous chemicals acquisition device 14. The access receipt information collecting device 13 and the hazardous chemical collecting device 14 are mounted on the gate case 1 at a portion outside the gate 2. The outside of the gate 2 is an upstream side in the passing direction of the passer.

The access voucher information acquisition device 13 acquires access voucher information for passers-by in an acquisition area, and the dangerous chemical acquisition device 14 acquires dangerous chemicals for passers-by in the acquisition area, wherein the acquisition area is positioned outside the gate 2.

Specifically, a predetermined range of the outside of the gate 2 at the entrance of the gate system 100 may be taken as the collection area. For example, a region between the gate 2 and a line having a predetermined distance from the gate 2 may be used as the collection region. The acquisition area may be preset according to the object to be acquired, the installation position of the acquisition device, and the like.

For example, in the case where the in-and-out voucher information collection device 13 and the hazardous chemical collection device 14 are mounted on the gate case 1, a portion of the passage between the gate cases 1 on the left and right sides, which portion is located outside the gate 2, may be used as a collection area.

The access voucher information acquisition device 13 is used for acquiring information, such as text information and/or picture information, on the access voucher carried by the passer. Here, the access certificate refers to any ticket or certificate indicating the access authority or identity of a passer, and examples thereof include train tickets, air tickets, subway tickets, entrance tickets, access cards, identification cards, passports, and driver licenses.

The hazardous chemical collecting device 14 is used to collect hazardous chemicals (hereinafter, also simply referred to as "hazardous chemicals"). Here, the hazardous chemicals include at least one of inflammable and explosive substances, drugs, and toxic gases. The flammable explosive may include: alcohol, gasoline, trinitrotoluene (TNT), hexogen (RDX), Black Powder (BP), Taian (PENT), Nitroglycerin (NG), Ammonium Nitrate (AN), but are not limited thereto. The drugs may include: opium, heroin, methamphetamine (methamphetamine), morphine, marijuana, cocaine, K powder, ecstasy, but not limited thereto. Toxic gases may include: ammonia, ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, hydrogen sulfide, but is not limited thereto. Here, the hazardous chemical may be solid particles, or may be liquid or gas.

The access receipt information collection device 13 and the hazardous chemical collection device 14 are functionally divided, and may be physically integrated or separate devices. For example, both the access ticket information collection device 13 and the hazardous chemical collection device 14 may share a partial structure, such as an access ticket insertion structure or the like. The access receipt information collection device 13 may be implemented by an existing device such as a card reader.

Since the dangerous chemical collecting device 14 is installed at a portion outside the gate 2 on the gate housing 1, the collecting and detecting functions of the dangerous chemicals can be integrated on the gate housing of the gate system. Further, collection of hazardous chemicals can be performed outside the gate 2 in parallel with collection of the access certificate information.

< dangerous chemical Collection device 14>

Hereinafter, a specific embodiment of the hazardous chemical collecting apparatus 14 will be described in detail.

(example 1)

In example 1, the collection of the access certificate information and the dangerous chemical is performed for the access certificate. The reason why the access receipt is used as the collection object of the dangerous chemicals is that, in general, a carrier of the dangerous chemicals has a trace amount of dangerous chemicals left on hands during the manufacturing and carrying processes, and transfers the dangerous chemicals to clothes, a pocket, the access receipt and the like. Therefore, the collection is performed with the access voucher as the target, and the dangerous chemicals satisfying the detection sensitivity of the dangerous chemical detection device can also be collected. For example, the drug addict may have drug powder on his hand or drugs in sweat on his hand, and when taking out the certificate, he will stick to the surface of the certificate, so as to collect the certificate and collect the drugs.

Thus, in embodiment 1, the hazardous chemical collecting apparatus 14 includes: a vibrating portion 141 and a collecting portion 142 (see fig. 3 for example 3 described later). The vibrating portion 141 is a member capable of vibrating the access ticket. The collecting unit 142 is a member capable of collecting hazardous chemicals that have come off the access certificate. The collecting part 142 is located below the vibrating part 141 and the access voucher. The access voucher at this time can be supported by an access voucher support portion and the like. The collecting unit 142 is connected to a dangerous chemical detection device 60 described later, and transfers the collected dangerous chemical to the dangerous chemical detection device 60 to perform detection analysis. The collecting part 142 may be a tapered collecting member having a large upper portion and a small lower portion in a longitudinal section.

The vibrating portion 141 may include a driving mechanism and a moving mechanism, wherein the driving mechanism is connected to the moving mechanism and drives the moving mechanism to perform a translational motion or a rotational motion. The movement mechanism applies vibration to the in-out voucher in the moving process. The movement mechanism may be a tapping mechanism or a shaking mechanism.

For example, the drive mechanism receives a control signal (e.g., a pulse signal) from the control device 40 and, in response to the control signal, moves the movement mechanism between a first limit position away from the access document and a second limit position proximate to the access document to impart a vibration to the access document surface.

The drive mechanism may be an electromagnet, a motor, or the like, and any component that can move the movement mechanism between the first limit position and the second limit position is sufficient. The movement mechanism may be, for example, a knocking portion for knocking the access ticket or a shaking portion for shaking the access ticket, but is not limited thereto, and may be any member that can vibrate the access ticket during movement. For example, the striking unit may be a hammer member that strikes the access ticket when moving from the first restriction position to the second restriction position. For example, the shaking portion may be a holding member that holds the access ticket and shakes off the hazardous chemical attached to the access ticket while the access ticket reciprocates between the first limit position and the second limit position.

The first and second restricting positions may be defined in advance according to a distance between the moving mechanism and another structure such as an access document supporting portion (e.g., a holder), and may be positions where the moving mechanism does not contact another peripheral structure. In other words, the relative position between the vibrating portion 141 and the in-out document support portion is fixed. Specifically, the relative positions of the first and second restricting positions and the document access support portion are fixed. For example, the relative positions of the holder base of the document support part and the fixed mount of the vibration part may be fixed by connecting them.

As an example, when the driving mechanism comprises a rotary electromagnet and the movement mechanism comprises a rotary shaft and a knocking head, the rotary electromagnet drives the rotary shaft and the knocking head to rotate, and the knocking head knocks the surface of the in-out document to enable the dangerous chemical to fall off from the surface of the in-out document. At this time, the control device 40 supplies a control signal (for example, a pulse signal) that alternately cycles positive and negative to the rotary electromagnet. When the rotating electromagnet is supplied with a positive 24V current, the rotating shaft rotates anticlockwise to a first limiting position, when the rotating electromagnet is supplied with a negative 24V current, the rotating shaft rotates clockwise to a second limiting position, and the knocking head knocks the in-out voucher once. The control device 40 provides a positive and negative alternate control signal to the rotary electromagnet, and the movement mechanism completes one knocking of the in-out voucher.

As described above, the vibration unit 141 vibrates the access receipt by, for example, knocking or shaking, so that the hazardous chemical attached to the surface of the access receipt is detached from the access receipt, thereby effectively collecting the hazardous chemical. In particular, particles of dangerous chemicals having no volatility can be easily detached from the access certificate, and a good collecting effect is achieved.

The hazardous chemical collecting apparatus 14 described above may be shared with the access certificate information collecting apparatus 13. In other words, the access receipt information collecting device 13 collects information of the access receipt supported by the access receipt supporting portion. Through the partial structure of discrepancy voucher information collection device 13 and dangerous chemical collection device 14 sharing, can be easily with dangerous chemical collection device 14 with discrepancy voucher information collection device 13 integration together, can make the structure compacter, realize the miniaturization of equipment easily. In addition, the access voucher information collection and the dangerous chemical collection are easily started simultaneously through the operation that the access voucher is inserted into a card reader and the like.

In this case, the installation positions of the access certificate information collection device 13 and the hazardous chemical collection device 14 are preferably the portions outside the gate 2 of the gate case 1. In this case, the collection area may be set to a range in which the passer can provide the access ticket to the access ticket support, for example, a card reading area, or the collection area may be set without addition, and it is determined that the collection area is occupied when the access ticket is provided to the access ticket support. More preferably, the upper surface of the gate casing 1 or the inner portion of the gate casing 1 is located at an upper position. This facilitates the insertion of the access vouchers and the like by passers-by in a standing position.

In addition, in embodiment 1, since the access ticket is targeted, it is not necessary to collect the dangerous chemical from the body of the passer, and the collection of the dangerous chemical can be started simultaneously and easily by the original operation required for the authentication of the passer inserting the access ticket into the access ticket reader. Dangerous chemical collection process can go on in full-automatic, need not security check personnel and passerby's manual operation, can reduce personnel's work load, improve collection efficiency, improve passerby's current experience. In addition, because the in-out voucher information acquisition and the dangerous chemical acquisition are executed in parallel, the acquisition time can be effectively shortened.

In addition, because need not to carry out dangerous chemical through visible modes such as test paper and gather, can be under the condition that passerby's personnel are not aware of, promptly, under the noninductive state, carry out dangerous chemical and gather and detect, consequently, be difficult to arouse suspicious personnel's attention, be favorable to catching suspicious personnel such as drug carriers. In other words, the non-sensory detection effect is good.

(example 2)

In embodiment 2, the hazardous chemical collecting apparatus 14 includes: an air pump 145, an air blowing pipe 143, and an air suction pipe 144 (see fig. 3 related to embodiment 3 described later), wherein the air pump 145 is connected to the air blowing pipe 143 and the air suction pipe 144, and can provide blowing force and suction force to the air blowing pipe 143 and the air suction pipe 144, respectively.

The outlet of the outlet pipe 143 and the inlet of the inlet pipe 144 may be disposed to face each other. The number of the air pumps 145 may be two, and the two air pumps are respectively connected to the air blowing pipe 143 and the air suction pipe 144.

The air inlet of the air suction pipe 144 is provided below the in-out voucher and the in-out voucher information collection device 13, the air outlet of the air blowing pipe 143 is provided above the in-out voucher information collection device 13, and a plurality of air outlets may be provided above or around the in-out voucher. The diameter of the insufflation port is preferably larger than the insufflation tube 143. The air blown out from the air blowing pipe 143 blows through the access ticket inserted into the access ticket information collecting apparatus 13 and is introduced into the air suction pipe 144. The suction pipe 144 is connected to the hazardous chemical detecting device 60 and transfers the collected hazardous chemical to the hazardous chemical detecting device 60.

As described above, in embodiment 2, the in-and-out voucher can be blown and sucked through the blowing pipe 143 and the suction pipe 144, respectively. In example 2, by collecting hazardous chemicals with the use of the access certificate as a target, the collection time can be shortened and the effect of non-sensitive detection can be obtained as in example 1. And is particularly suitable for collecting dangerous chemicals with volatility.

(example 3)

Hereinafter, embodiment 3 of the dangerous chemical collecting apparatus 14 will be described with reference to fig. 3. Fig. 3 is a sectional view of the upper part of the gate case 1 taken in the longitudinal direction.

As shown in fig. 3, in embodiment 3, the hazardous chemical collecting apparatus 14 includes: a vibration part 141, a collection part 142, an air pump 145, an air blowing pipe 143 and an air suction pipe 144. The structure, positional relationship and connection relationship of the air pump 145, the air blowing pipe 143 and the air suction pipe 144 are the same as those of embodiment 2. The vibrating portion 141 and the collecting portion 142 are the same as in embodiment 1.

The air outlet of the air blowing pipe 143 is provided above or around the vibrating part 141 and the in-out voucher information collection device 13. Preferably, the vibration part 141 is not hindered from moving (e.g., is located outside the first limit position).

The suction port of the suction pipe 144 is provided below the vibrating portion 141 and the in-out voucher information collection device 13, and the suction pipe 144 is connected to the bottom of the collection portion 142. The air blown out from the air blowing pipe 143 blows through the vibrating portion 141 and the in-out voucher provided in the in-out voucher information collecting apparatus 13, and enters the air suction pipe 144. The suction pipe 144 is connected to the hazardous chemical detecting device 60 and transfers the collected hazardous chemical to the hazardous chemical detecting device 60.

In embodiment 3, not only the vibration is applied to the access certificate, but also the air blowing and the air suction are performed to the access certificate, so that the amount of the collected hazardous chemicals can be further increased, thereby increasing the detection rate of the hazardous chemicals and reducing the omission ratio, compared with embodiment 1 in which only the vibration is applied and embodiment 2 in which the hazardous chemical collection is performed only by the structure of the air blowing and the air suction.

(example 4)

The hazardous chemical collecting device 14 further includes a paper taking device and a test paper recovering device (not shown). The test strip taking device stores and provides test strips for collecting dangerous chemicals. The test paper recovery device is used for recovering test paper after dangerous chemicals are collected. The paper taking device and the test paper collecting device are preferably installed inside the gate casing 1, but are not limited thereto. After the test piece is collected by the test piece collecting device, the opening and closing of the shutter 2 may be controlled in conjunction with the collected test piece.

The technology of carrying out chemical collection and detection with the test paper is current, through taking the device with paper and combining together test paper recovery unit and floodgate machine system, can realize the floodgate machine system with simple structure and combine with dangerous chemical safety inspection system, can shorten total transit time with simple mode.

(example 5)

The gate machine case 1 comprises two gate machine cases respectively positioned at the left side and the right side of the gate 2, a blowing hole is arranged on the gate machine case at one side, and a suction hole is arranged on the gate machine case at the other side opposite to the blowing hole. At this time, the collection area may be set to a range where the blow-up hole and the suction hole are provided.

The hazardous chemical collecting device 14 includes the air blowing hole and the air suction hole described above. The shape of the air blowing hole and the air suction hole may be arbitrary as long as they are provided to face each other on both sides of a passage through which a person passes. The number of the air blowing holes and the number of the air suction holes may be plural.

The dangerous chemicals can be collected by blowing air to the body and/or baggage of the person through the blowing holes and collecting the gas after being blown through the body and/or baggage of the person through the suction holes.

Any of the above embodiments 1 to 5 may be combined to collect hazardous chemicals in a multiple manner, so that the amount of the collected hazardous chemicals can be increased, and the accuracy of detection can be further improved.

Returning to FIG. 1, the gate system 100 is next described. The gate system 100 may further include: at least one of the guide screen 15, the pass indicator light 16 and the trailing detection device 17 may be further mounted on the gate casing 1, in other words, at least one of the guide screen 15, the pass indicator light 16 and the trailing detection device 17 may be further mounted on the gate casing 1. The guide screen 15 is used to display a prompt message or the like to the passer, for example, to prompt the passer to put an access ticket into the access ticket information collection device 13. The traffic light 16 is used to indicate whether or not a traffic person can pass through the gate 2, and may be an LED light showing an arrow shape or the like, for example, an arrow showing green indicates that the traffic person can pass through. The trailing detection device 17 is used to detect whether a person is trailing, and the trailing detection device 17 may be any existing device capable of detecting a trailing person.

The gate system 100 further includes: an authentication device 50 and a hazardous chemical detection device 60.

The authentication device 50 is connected to the access credential information collection device 13, receives access credential information collected by the access credential information collection device 13, and authenticates the identity of a passer-by who passes through the gate passage 30 based on the access credential information collected by the access credential information collection device 13. The identity authentication is to determine whether the passer-by has the right to pass through the gate system 100.

The identity authentication device 50 may include a face recognition module 51 and a testimony comparison module.

The face recognition module 51 is used for recognizing the face of the passer-by passing through the gate passageway 30 and obtaining a face image. The face recognition module 51 may include a camera or the like that photographs a human face. The face recognition module 51 may also have an infrared temperature measurement function, a display function, and the like.

The face recognition module 51 may include a face recognition display screen having a photographing and displaying function. The face recognition module 51 may be disposed on the gate housing 1. In addition, the face recognition module 51 may be integrated with the guide screen 15 and installed on the gate housing 1, that is, the guide screen 15 has not only a function of displaying guide information but also a function of photographing a face image.

The testimony comparison module is used for comparing testimonies, and the testimony comparison is to compare the face image with the picture on the access voucher to judge whether abnormity exists or not. For example, if the face image matches the photograph on the access certificate, it is determined that there is no abnormality in the authentication result, and if the face image does not match the photograph on the access certificate, it is determined that there is an abnormality.

The identity authentication device 50 may include an identity information comparison module. The identity information comparison module is used for comparing the personnel identity information acquired through the access certificate information acquisition with the personnel permission information stored in the internal or external memory of the gate system 100 to judge whether the abnormality exists. Here, the personal authority information stored in the internal or external memory of the gate system 100 may be white list information or black list information. For example, it may be determined that there is no abnormality when the collected personal identification information is consistent with the white list information, or determined that there is an abnormality when the collected personal identification information is inconsistent with the black list information, or determined that there is an abnormality when the collected personal identification information is consistent with the black list information, or determined that there is no abnormality when the collected personal identification information is inconsistent with the black list information.

The identity authentication device 50 may also include a face comparison module instead of a witness comparison module. The face comparison module compares the face image recognized by the face recognition module 51 with the face image information stored in the internal or external memory of the gate system 100. For example, if the face image recognized by the face recognition module 51 matches the face image information stored in the internal or external memory of the gate system 100, it is determined that the authentication result is abnormal, and if the face image does not match the face image information, it is determined that there is an abnormality.

The testimony comparison module, the identity information comparison module and the face comparison module can be installed in the gate case 1, can be physically and independently arranged with the gate case 11, and can be contained in the control device 40. The testimony comparison module, the identity information comparison module and the face comparison module can be integrated into a hardware to be realized.

Next, as shown in fig. 2, the dangerous chemical detecting device 60 is connected to the dangerous chemical collecting device 14, and receives the dangerous chemical collected by the dangerous chemical collecting device 14 and detects it.

The hazardous chemical detection device 60 may include at least one of a flammable and explosive substance detection module, a drug detection module, and a toxic gas detection module. The trace detector can be used for realizing a combustible and explosive substance detection module and a drug detection module. The trace detector can detect inflammable and explosive substances and drugs. The detection module of the hazardous chemical detection apparatus 60 may be set to correspond to the type of the collected hazardous chemical.

Aiming at the detection of inflammable and explosive objects, drugs and toxic gases, for example, collected dangerous chemicals can be used as the objects to be detected and divided into 3 parts (if only two of the objects are detected, the objects are divided into 2 parts) to be respectively sent into an inflammable and explosive object detection module, a drug detection module and a toxic gas detection module.

Preferably, the trace detector of the synchronous dual-mode ion mobility spectrometry technology is used for realizing the inflammable and explosive detection module and the drug detection module, and at the moment, the detection results of the inflammable and explosive and the drug can be obtained simultaneously for the same object to be detected without switching modes. The detection time can be shortened, and the detection accuracy can be improved.

(method of controlling Gate System)

Hereinafter, a method of controlling the gate system according to the first embodiment will be described in detail. Namely, a control method executed in the control device 40.

The control device 40 may be connected to other components of the gate system 100 such as the gate 2, the entrance/exit voucher information collecting device 13, the dangerous chemical collecting device 14, the identification device 50, the dangerous chemical detecting device 60, the guide panel 15, the traffic light 16, and the trailing detecting device 17, and controls the operations thereof.

The control device 40 may be installed inside the gate enclosure 1, or may be provided physically independently of the gate enclosure 1. The control device 40 may be provided as a whole, or may be provided separately in different devices or components in accordance with the functions.

The control device 40 may be a personal computer, a single chip microcomputer, or the like, and may include, for example, a CPU (Central processing unit), a ROM (Read Only Memory) in which programs and various data are stored, and a RAM (Random access Memory) used as a work area of the CPU. The CPU executes a program stored in the ROM or the storage section.

When a person arrives at the acquisition area outside the gate 2, the control device 40 controls the access voucher information acquisition device 13 and the dangerous chemical acquisition device 14 to acquire access voucher information and dangerous chemicals in parallel, controls the identity authentication device 50 to perform identity authentication after the access voucher information acquisition is completed, controls the dangerous chemical detection device 60 to perform dangerous chemical detection after the dangerous chemical acquisition is completed, and controls the gate to be opened and closed according to the authentication result of the identity authentication device and the detection result of the dangerous chemical detection device.

Specifically, as shown in fig. 4, in step S11, it is determined whether or not a passer-by has come to the collection area outside the gate 2. I.e. to determine whether a person is present in the collection area.

An infrared sensor, a radar sensor and the like which can detect people can be arranged in the acquisition area, and whether people enter the acquisition area is judged.

Instead of installing an additional sensor, the access voucher is provided to the access voucher information acquisition device 13 by the passer-by, and it is determined that someone enters the acquisition area.

When a pedestrian comes to the collection area of the gate system 100 (step S11: yes), the process proceeds to step S12 and step S13 at the same time.

In step S12, the access ticket information collection device 50 is controlled to collect information on the access ticket carried by the passer, that is, to collect access ticket information.

In step S13, the dangerous chemical collecting device 60 is controlled to collect dangerous chemicals.

In step S14, it is determined whether the collection of access ticket information by the access ticket information collection device 50 is completed, and if the collection is completed (step S14: yes), the process proceeds to step S16.

In step S15, it is determined whether or not the collection of the hazardous chemical by the hazardous chemical collecting device 60 is completed, and if the collection is completed (step S15: yes), the process proceeds to step S17.

In step S16, the authentication device 50 is controlled to perform an authentication process.

In step S17, the control unit controls the hazardous chemical detection device 60 to perform the hazardous chemical detection process. The specific processing can be found in the above description of the hazardous chemical detection apparatus 60.

If the identity authentication processing at step S16 and the hazardous chemical detection processing at step S17 are both completed and there is no abnormality (step S18: yes), the process proceeds to step S19. In step S19, the shutter 2 is opened.

If the authentication processing in the step S16 and the hazardous chemical detection processing in the step S17 are abnormal (no in the step S18), the routine proceeds to the step S20. In step S20, an alarm is issued without opening the shutter 2. If there is no abnormality (step S18: YES), the flow proceeds to step S19, where the shutter 2 is opened.

< specific examples of Collection of Access voucher information and Collection of hazardous chemical >

Hereinafter, the access receipt information collection by the access receipt information collection device 13 and the hazardous chemical collection process by the hazardous chemical collection device 14 will be specifically described.

In embodiment 1, both the access receipt information collection device 13 and the hazardous chemical collection device 14 collect access receipts. This embodiment can be realized by the structure of embodiment 1 of the hazardous chemical collecting apparatus 14 described above.

Fig. 5 is a flowchart illustrating the access ticket information collecting apparatus 13 and the hazardous chemical collecting apparatus 14 performing the steps S12 and S13 in fig. 4 in parallel.

Specifically, in step S131, it is determined whether or not an access voucher is provided to the access voucher support section of the access voucher reader (corresponding to the access voucher information collection device 13) in the gate box 1, and when an access voucher is provided (step S131: yes), the process proceeds to step S132. The above-mentioned "provided" may be placed in a predetermined distance above the access receipt support portion, or may be inserted into the access receipt support portion, that is, the method includes a normal insertion, swiping, and scanning, as long as the access receipt information collection device 13 can be provided with the access receipt. This step S131 may also be considered as an example of the step S11 of fig. 4 described above.

In step S132, the access voucher is scanned and identified, so as to collect the picture and/or text information on the access voucher.

In step S133, it is determined whether the scanning and identification of the access voucher are completed, and if the scanning of the access voucher is completed (step S133: yes), the process proceeds to steps S134 and S135. If the access voucher scanning is not completed (step S133: NO), the access voucher scanning can be continued and whether the access voucher scanning is completed or not can be periodically judged.

In step S134, the collected access credential information is transmitted to the authentication device 50.

In step S141, a vibration is applied to the access ticket.

The vibration of the above step S141 may be performed as follows: the control drive mechanism receives a control signal (e.g., a pulse signal) from the control device 40, and in response to the control signal, the drive mechanism moves the movement mechanism between a first limit position away from the access credential and a second limit position proximate to the access credential to impart a vibration to the access credential. Specific modes can be found in the description of embodiment 1 of the hazardous chemical collecting apparatus 14.

In step S142, it is determined whether the vibration of step S141 is completed. If the vibration is completed (step S142: YES), the process proceeds to step S135 and step S143. If the vibration of the access voucher is not finished (step S142: No), the vibration of the step S141 can be continuously performed, and whether the vibration is finished or not can be periodically judged.

In step S143, the collected hazardous chemical is sent to the hazardous chemical detection device 60. After step S143, the process may proceed to step S17 in fig. 4, and the hazardous chemical detection device 60 is controlled to perform hazardous chemical detection.

In step S135, it is determined whether the collection of the access receipt information and the collection of the hazardous chemical are both completed, and if both are completed (step S135: yes), the process proceeds to step S136.

In step S136, the retrieval of the access ticket is prompted. For example, the user may be prompted to take out the entry ticket by displaying a prompt on the guide screen 15 or by turning on a prompt light, or the entry ticket may be automatically popped up.

Among the above-described steps of fig. 5, the steps S131 to S136 correspond to the collection of access ticket information (corresponding to steps S11 to S13 in fig. 4), and the steps S141 to S143 correspond to the collection of hazardous chemicals (corresponding to steps S14 to S15 in fig. 4).

Embodiment 1 of the hazardous chemical collecting process can obtain the same effects as embodiment 1 of the hazardous chemical collecting apparatus 14.

(example 2)

Example 2 is also an example in which access voucher information and collection of dangerous chemicals are performed with access voucher as a subject. This embodiment can be realized by the structure of embodiment 2 of the hazardous chemical collecting apparatus 14 described above.

Fig. 6 is a flowchart showing a specific example in which the access ticket information collection apparatus 13 and the hazardous chemical collection apparatus 14 perform access ticket information collection and hazardous chemical collection in parallel.

Since steps S131 to S136 and S143 are the same as those in embodiment 1, they are not repeated.

In step S144, a timer is started, which is used to time the time for blowing and sucking air into and out of the voucher.

In step S145, the access voucher is blown and sucked. Specifically, the control device 40 may control an air pump connected to the air blowing pipe and the air suction pipe to perform air suction and air blowing.

In step S146, it is determined whether the timer has reached a predetermined time. If the timer has reached a predetermined time (step S146: YES), the air blowing and air suction of the access receipt is completed, and the process proceeds to step S135 and step S143.

Among the above-described steps of fig. 6, the steps S131 to S136 correspond to the collection of access ticket information (corresponding to steps S11 to S13 in fig. 4), and the steps S143 to S146 correspond to the collection of hazardous chemicals (corresponding to steps S14 to S15 in fig. 4).

Embodiment 2 of the hazardous chemical collecting process can obtain the same effect as embodiment 2 of the hazardous chemical collecting apparatus 14.

(example 3)

In embodiment 3, both the access ticket information collection device 13 and the hazardous chemical collection device 14 collect access tickets. This embodiment can be realized by the structure of embodiment 3 of the hazardous chemical collecting apparatus 14 described above.

Fig. 7 is a flowchart showing a specific example in which the access ticket information collection apparatus 13 and the hazardous chemical collection apparatus 14 perform the access ticket information collection and the hazardous chemical collection in parallel.

Since steps S131 to S136 are the same as in embodiment 1 and steps S141 to 146 are the same as in embodiment 2, they are not repeated.

The point of difference from embodiment 1 is that if it is determined in step S142 that the vibration has been completed (step S142: yes), the flow proceeds to steps S135 and S146.

Since the step S146 is not performed until it is determined in the step S142 that the vibration is completed, the expiration of the timer in the step S146 also indicates that the collection of the hazardous chemical is completed, and the step S143 is performed after the step S146, and the collected hazardous chemical is sent to the hazardous chemical detection device 60.

In step S146, the timer arrival time (i.e., the time for performing the air suction and the air blowing) is preferably set to be longer than the time for vibrating the access voucher in step S141, so as to ensure that the air blowing and the air suction are performed on the access voucher all the time during the vibration of the access voucher, thereby increasing the collection amount of the hazardous chemicals.

Among the above-described steps of fig. 7, the steps S131 to S136 correspond to the collection of access ticket information (corresponding to steps S11 to S13 in fig. 4), and the steps S141 to S146 correspond to the collection of hazardous chemicals (corresponding to steps S14 to S15 in fig. 4).

Embodiment 3 of the hazardous chemical collecting process can obtain the same effect as embodiment 3 of the hazardous chemical collecting apparatus 14.

(example 4)

Example 4 is an example in which access voucher information is collected for access vouchers, and dangerous chemicals are collected for passers-by bodies and/or luggage. This embodiment can be realized by the structure of embodiment 4 of the hazardous chemical collecting apparatus 14 described above.

The access voucher information collection in the embodiment 4 is the same as the steps of the above embodiment 1 except that the step S135 is not included, that is, the steps S131 to 134 and S136 are included, and the hazardous chemical collection is different from the embodiment 1.

Hereinafter, the hazardous chemical collecting process of example 4 will be described.

Fig. 8 is a flowchart showing a specific example of hazardous chemical collection performed by the hazardous chemical collection device 14.

In step S241, the test piece taking device is controlled to supply the test piece. The providing may be provided in a pop-up or the like. After the test paper is supplied, a guidance screen 15 provided in the gate housing 1 may display a prompt for a passer to take out the test paper and put it into an inlet of the test paper collecting apparatus after wiping the body and/or the surface of the baggage. Alternatively, a paper notice is attached to the gate box 1, and the notice is described with the above-mentioned contents.

In step S242, it is detected whether or not there is a test strip subjected to dangerous chemical collection at the input port of the test strip collecting device, where the test strip subjected to dangerous chemical collection is a test strip after a person wipes the surface of the body and/or the baggage from the test strip provided by the test strip taking device.

In step S243, the test strip collection device is controlled to collect the test strip subjected to the collection of the hazardous chemical.

In step S244, the test paper is sent to the dangerous chemical detecting means 60.

Embodiment 4 of the hazardous chemical collecting process can obtain the same effect as embodiment 4 of the hazardous chemical collecting apparatus 14.

(example 5)

Embodiment 5 can be realized by the structure of embodiment 4 of the hazardous chemical collecting apparatus 14 described above.

The control device 40 can control the blowing holes to blow air to the body and/or luggage of the person and control the suction holes to collect gas, thereby collecting dangerous chemicals.

< authentication processing >

Hereinafter, the identity authentication process performed by the identity authentication device 50 will be described in detail with reference to fig. 9 to 10. Namely, the specific processing procedure of step S16.

Specifically, the S16 step may include: and S161. In step S161, the control identity information comparison module compares the personnel identity information obtained through the access credential information collection with the personnel authority information stored in the internal or external memory of the gate system 100. The personnel authority information may be information indicating access authority, and may be white list information, black list information, or the like. For example, it may be determined that there is no abnormality when the collected personal identification information is consistent with the white list information, or determined that there is an abnormality when the collected personal identification information is inconsistent with the black list information, or determined that there is an abnormality when the collected personal identification information is consistent with the black list information, or determined that there is no abnormality when the collected personal identification information is inconsistent with the black list information. The personnel identity information acquired through the access voucher information acquisition can be information representing access authority, and can comprise picture information such as a photo on the access voucher and/or character information on the access voucher. By this processing, it is possible to ensure that the access ticket is an access ticket for an authorized person, and it is ensured that only an authorized person can pass through the gate system 100.

The step of S16 may further include: and S162 and S163, in the S162, controlling the face recognition module 51 to recognize the face of the passer who passes through the gate passageway 30 and obtain a face image, and in the S163, controlling the testimony comparison module to compare the face image with a picture on the access voucher obtained by the access voucher information acquisition and judging whether the access voucher is abnormal or not. For example, if the face image matches the photograph on the access certificate, it is determined that there is no abnormality in the authentication result, and if the face image does not match the photograph on the access certificate, it is determined that there is an abnormality. By such processing, the matching of the face and the access certificate information can be ensured, and the passer-by can be prevented from falsely using the access certificate of other people. For example, an unauthorized person may pass through the gate system 100 with an access credential of an authorized intruder.

In addition, the step S16 may include: in addition, the step S16 may include, instead of the step S163, a step S164, and in the step S164, the face image recognized in the step S162 may be compared with face image information stored in a memory inside or outside the gate system 100. That is, the step S16 includes a step S162 of performing face recognition and a step S164 of performing face comparison. For example, if the face image recognized in step S162 matches the face image information stored in the internal or external memory of the gate system 100, it is determined that the authentication result is abnormal, and if not, it is determined that there is an abnormality. By such processing, even if detailed comparison of the access certificate information is not performed, it is possible to prevent unauthorized persons from entering the gate system 100 by only comparing the face images.

As shown in fig. 9, the step S16 may include steps S161 to S163, and when both the results of the determination in the steps S161 and S163 are abnormal, it is determined that the authentication result is abnormal, and when either one of the results of the determination in the steps S161 and S163 is abnormal, it is determined that the authentication result is abnormal. Through the processing, the matching of the face and the access certificate information can be ensured, the access certificate can be ensured to be the access certificate of the authorized personnel, and the reliability of identity authentication can be improved.

As shown in fig. 10, the step S16 may include steps S161 to S162 and S164, and when the determination results of the steps S161 and S164 are both abnormal, it is determined that the authentication result is abnormal, and if any one of the steps S161 and S164 is abnormal, it is determined that the authentication result is abnormal. Through the processing, the matching of the human face and the pre-stored human face image can be ensured, the access certificate of authorized personnel can be ensured, and the reliability of identity authentication can be improved.

As described above, in the first embodiment, since the collection of the entrance/exit certificate information and the identification authentication are performed in parallel with the collection and detection of the hazardous chemical, the functions of collecting and detecting the hazardous chemical can be increased without increasing the passage time as compared with the gate system that performs only the identification authentication.

< second embodiment >

Fig. 11 is a schematic diagram showing a schematic configuration of a gate system according to a second embodiment of the present invention. Fig. 12 is a schematic diagram showing functional modules of a gate system according to a second embodiment of the present invention. The second embodiment differs from the first embodiment in that the second embodiment is a double gate structure, unlike the single gate structure of the first embodiment.

As shown in FIGS. 11-12, the gate system 200 includes: the system comprises an entrance gate 10, an exit gate 20, a gate passage 30, a control device 40, an entrance and exit voucher information acquisition device 13, a dangerous chemical acquisition device 14, an identity authentication device 50 and a dangerous chemical detection device 60. The entrance gate 10 includes a gate case 11 and a gate 12 (also referred to as an "entrance gate"). The gate 12 is installed on the gate case 11. The exit gate 20 includes a gate case 21 and a gate 22 (also referred to as an "exit gate"). The shutter 22 is mounted on the shutter case 21. The gate housings 11 and 21 may include two cases at the left and right sides of the gate passage 30, respectively.

A gate passageway 30 is located between gate 12 at the inlet and gate 22 at the outlet. The gate 12 at the entrance and the gate 22 at the exit may not be located at the edges of the

gate housings

11 and 21, and in this case, both side walls of the gate passage 30 include a box body and a side wall body portion 31 which are a part of the

gate housings

11 and 21. In other words, the side wall body portion 31 is a portion other than the entrance gate case 11 and the exit gate case 21 out of the two side walls of the gate passage. The sidewall body 31 is generally formed of a plate material to secure a shielding effect while saving materials. However, the side wall body 31 may include a case to which another detection module can be attached. The gate passage 30 may have a width of 1 to 1.5m and a length of 1.5 to 2 m. Preferably, the gate passage 30 has a width of 1m and a length of 1.5 m.

When there is no passerby, the gate 12 of the entrance gate 10 and the gate 22 of the exit gate 20 are both in a closed state. When a passer-by comes to the gathering area at the entrance of the gate 12 of the entrance gate 10, if the gate 12 of the entrance gate 10 is opened, the passer-by enters the gate passageway 30 through the gate 12, and then, if the gate 22 of the exit gate 20 is opened, the passer-by goes out of the gate passageway 30 through the gate 22. As shown in fig. 11, a plurality of such gate systems 100 may be arranged in a lateral direction.

The access ticket information collection device 13, the hazardous chemical collection device 14, the identification device 50, the hazardous chemical detection device 60, and the like are the same as those of the first embodiment and will not be described here.

Specifically, the access voucher information collection device 13 and the hazardous chemical collection device 14 may be installed at a portion of the entrance gate housing 11 outside the gate passage 30. Thus, the collection and detection functions of hazardous chemicals can be integrated on the gate cabinet 11 at the entrance of the gate system. Further, collection of hazardous chemicals can be performed outside the gate passage 30 in parallel with collection of access voucher information.

In embodiments 1 to 3 of the hazardous chemical collecting device 14, the installation positions of the access receipt information collecting device 13 and the hazardous chemical collecting device 14 are preferably the upper surface of the gate case 11 of the entrance gate 10 or the upper position of the inside of the gate case 11. This facilitates the insertion of the access vouchers and the like by passers-by in a standing position.

The paper taking device and the test paper recovering device of embodiment 4 of the hazardous chemical collecting device 14 are specifically installed to the gate case 11 of the inlet gate 10. Preferably inside it, but not limited thereto. After the test piece is collected by the test piece collecting device, the gate 12 of the gate 10 at the inlet may be opened in conjunction with the collected test piece.

In embodiment 5 of the hazardous chemical collecting apparatus 14, the inlet gate 10 includes two gate housings respectively located on the left and right sides of the gate 12, the gate housing on one side being provided with an air blowing hole, and the gate housing on the other side being provided with an air suction hole opposite to the air blowing hole.

Specifically, the face recognition module 51 may be provided on the gate passageway 30 or the gate box 21. Preferably, the face recognition module 51 is disposed on the gate case 21 at a position inside the gate 22 (within the gate tunnel 30). The face recognition module 51 may be installed on the

same gate case

11 or 21 as the access certificate information collection device 13. At this time, the passer who provides the access ticket at the access ticket information collection device 13 can more easily enter the shooting range of the camera of the face recognition module 51.

The testimony comparison module, the identity information comparison module and the human face comparison module can be installed in the

gate case

11 or 21, can be physically and independently arranged with the gate case 11 at the inlet 10 and the gate case 20 at the outlet 20 and the gate channel 30, and can also be contained in the control device 40.

(method of controlling Gate System)

Hereinafter, a method of controlling the gate system according to the second embodiment will be described in detail. Namely, a control method executed in the control device 40.

In this case, the control device 40 may be connected to other components of the gate system 100, such as the gate 12 of the entrance gate 10, the gate 22 of the exit gate 20, the entrance/exit certificate information collection device 13, the dangerous chemical collection device 14, the identification device 50, the dangerous chemical detection device 60, the guide screen 15, the traffic light 16, and the tail detection device 17, to control the operations thereof.

When a person enters the gate system 100, the gate 12 of the gate 10 at the entrance is in a closed state, and the person does not enter the gate passage 30, the control device 40 controls the access credential information collection device 13 to collect information on an access credential carried by the passerby, controls the hazardous chemical collection device 14 to collect hazardous chemicals in parallel, controls the gate 12 of the gate 10 at the entrance to be opened after the access credential information collection and the hazardous chemical collection are completed, and controls the identity authentication device 50 and the hazardous chemical detection device 60 to perform identity authentication and hazardous chemical detection in parallel.

Hereinafter, the flow of control performed by the control device 40 will be described in detail with reference to fig. 13. That is, fig. 13 is a flowchart showing a control flow executed by the control device 40.

The control device 40 may be installed inside the

gate enclosure

11 or 21, or may be physically provided independently of the

gate enclosure

11 or 21.

First, in step S101, it is determined whether or not a passer-by has arrived at the collection area at the entrance of the gate system 100. When a pedestrian comes to the acquisition area of the gate system 100 (step S101: yes), the process proceeds to step S102. If the collection area is empty (step S101: No), the step S101 is continued, and the user waits until the collection area is accessed.

In step S102, it is determined that the gate 12 of the entry gate 10 is in the closed state, that is, the state in which the passer-by cannot enter the gate tunnel 30 through the gate 12.

If the determination result in step S102 is yes, step S103 and step S104 are executed in parallel.

In step S103, the access ticket information collecting device 50 collects information on the access ticket carried by the passer, that is, collects access ticket information.

In step S104, the dangerous chemical collecting device 60 is controlled to collect dangerous chemicals.

The specific modes of the collection of the access receipt information in step S103 and the collection of the hazardous chemical in step S104 are the same as those described in the first embodiment 1, and therefore, the description thereof is omitted.

If the determination result in the step S102 is "no", the process proceeds to a step S105.

The gate 12 of the entrance gate 10 is in a closed state by default, since there is no person in the collection area and gate passageway 30. As described in step S113, the gate 12 is closed after the passer-by has passed through the entrance gate 10. Thus, the gate 12 of the entry gate 10 is not closed, possibly because the forward passer-by has not yet passed the gate 12.

Thus, in step S105, a pedestrian ahead is waited for to pass through the gate 12, and the gate 12 of the entrance gate 10 is closed.

Instead of performing the above-described processing of S102 and S105, the step S103 and the step S104 may be started directly in parallel when it is determined that the presence of the collecting area is present, based on whether or not the presence of the access ticket is provided to the access ticket information collecting device 50 and whether or not the presence of the collecting area is present in the step S101 is determined.

In step S106, it is determined whether the collection of the access receipt information in step S103 and the collection of the hazardous chemical in step S104 are both completed, and if both are completed (step S106: yes), the process proceeds to steps S107 to S109.

In step S107, the entrance gate 10 is controlled to open the gate 12. Here, before the gate 12 of the inlet gate 10 is opened (i.e., after yes at step S106 and before step S107), the following steps may be further included: it is judged whether or not there is a person in the gate passage 30, and when there is no person in the gate passage 30, the gate 12 is opened.

As can be seen, in the present invention, access credential information and hazardous chemical collection are performed in parallel prior to entering the gate pathway 30, i.e., outside the gate pathway 30.

If the time for collecting the access voucher information in the step S103 is set as T_{In-out voucher collection}Setting the time for collecting the dangerous chemicals in the step S104 as T_{Hazardous chemical collection}Then the waiting time of the passer at the entrance of the entrance gate 10 is Max (T)_{In-out voucher collection},T_{Hazardous chemical collection})。

Simultaneously with the start of the step S107, the steps S108 and S109 are started to be executed in parallel. Here, after step S107 is performed, step S108 and step S109 may be performed in parallel.

In step S108, the authentication device 50 is controlled to perform the authentication process. The specific form of the authentication process is the same as the step S16 of the first embodiment, and therefore, the description thereof is omitted.

In step S109, the hazardous chemical detection device 60 is controlled to perform the hazardous chemical detection process. The specific processing can be found in the above description of the hazardous chemical detection apparatus 60.

If the identity authentication processing in step S108 and the hazardous chemical detection processing in step S109 are both completed and there is no abnormality (step S110: yes), the process proceeds to step S111. If there is an abnormality in the authentication process or the hazardous chemical detection process (step S110: NO), the process proceeds to step S112.

In step S111, the outlet gate 20 is controlled to open the gate 22. While the shutter 22 is opened, the process returns to step S101. In other words, the access receipt information collection device 13 and the hazardous chemical collection device 14 are controlled to be in a state in which collection can be performed for the next person. The state in which the collection can be performed for the next pedestrian means that the processing after the step S101 can be performed as long as the next pedestrian enters the collection area (step S101: yes).

When the passage time for the pedestrian to move from outside the gate 12 (i.e., outside the gate tunnel 30) to inside the gate 12 (i.e., inside the gate tunnel 30) after opening the gate 12 of the entry gate 10 in step S106 is set as T_{Passage 1}The passage time of the person who passes through the gate passage 30 (before the gate 22) is set to T_{Passage 2}In the present invention, the gate 12 is opened in parallel with the authentication and the detection of the hazardous chemical, so that the passage time T can be used_{Passage 1}+T_{Passage 2}For authentication and hazardous chemical detection.

Therefore, if the time for performing the identity authentication in step S108 is T_{Identity authentication}The time for detecting the dangerous chemical in the step S100 is T_{Hazardous chemical substance detection}Then the time after the gate 12 of the inlet gate 10 is opened until the gate 22 of the outlet gate 20 is opened is Max (T)_{Passage 1}+T_{Passage 2}，T_{Identity authentication},T_{Hazardous chemical substance detection})。

In the present invention, since the identity authentication and the hazardous chemical detection are performed in parallel, in some embodiments, the time T for the identity authentication device 50 to perform the identity authentication can be achieved_{Identity authentication}And the time T for the dangerous chemical detection by the dangerous chemical detection device 60_{Hazardous chemical substance detection}Are all less than or equal to the time T for personnel to pass through the gate at the entrance_{Passage 1}And the time T of passage in the gate passage 30_{Passage 2}The sum (T) of_{Passage 1}+T_{Passage 2})。

In this case, it is preferable that the air conditioner,

T_{identity authentication}≤T_{Passage 1}+T_{Passage 2}And T is_{Hazardous chemical substance detection}≤T_{Passage 1}+T_{Passage 2}

Thus, Max (T)_{Passage 1}+T_{Passage 2}，T_{Identity authentication},T_{Hazardous chemical substance detection})＝T_{Passage 1}+T_{Passage 2}

At this time, the pedestrian moves in front of the gate 22 or just before the gate 22 (T or less)_{Passage 1}+T_{Passage 2}Time) of the first time period, the authentication and the detection of the dangerous chemical are finished, and therefore, the passer-by only needs to pass at a normal moving speed, and there is no need to wait for the completion of the authentication and the detection of the dangerous chemical in front of the gate 22.

If the passage time for the passer to move from the inside of the gate 22 (i.e., the inside of the gate passageway 30) to the outside of the gate 22 (i.e., the outside of the gate passageway 30) after the gate 22 is opened in step S110 is set to T_{Pass 3}Then total time T spent by personnel passing through the passageway_{General assembly}Comprises the following steps:

T_{general assembly}＝Max(T_{In-out voucher collection},T_{Hazardous chemical collection})+Max(T_{Passage 1}+T_{Passage 2}，T_{Identity authentication},T_{Hazardous chemical substance detection})+T_{Pass 3}

Wherein, as described above, access credential information collection and hazardous chemical collection are both performed concurrently outside of the gate pathway 30, so this portion of time is Max (T)_{In-out voucher collection},T_{Hazardous chemical collection}) While identity authentication and hazardous chemical detection are performed in parallel using the time that personnel are moving through the gate 12 and within the gate passageway 30, this portion of time being Max (T)_{Passage 1}+T_{Passage 2}，T_{Identity authentication},T_{Hazardous chemical substance detection})。

In contrast, in the prior art, only identity authentication is performed in the gate system, and a security inspection channel is additionally arranged for dangerous chemical collection and detection, so that the total consumed time T of the passer-by is shortened_{General assembly}' is: t is_{General assembly}’＝T_{In-out voucher collection}+Max(T_{Passage 1}+T_{Passage 2}，T_{Identity authentication})+T_{Pass 3}+T_{Hazardous chemical collection}+Max(T_{Hazardous chemical substance detection}+T_{Passage of security inspection channel}). Because passers pass through the gate system for identity authentication and the security inspection system for security inspection of hazardous chemicals in sequence, the gate system and the security inspection system do not overlap in time, the two times need to be added completely, and the total passing time is long.

Or, even if the security check channel is not additionally arranged and the security check is carried out in the gate machine channel (namely, the security check channel is considered to be arranged in the gate machine channel), after the scanning of the in-out certificate, the personnel enter the gate machine channel, the collection and the detection of dangerous chemicals are waited in the gate machine channel, the identity authentication such as face scanning, ID card comparison and the like is carried out, after the detection and the identity authentication of the dangerous chemicals are not abnormal, the gate of the gate machine at the outlet is opened, so that the total consumption time T of the passerby is shortened under the condition that the personnel pass_{General assembly}"is: t is_{General assembly}”＝T_{In-out voucher collection}+T_{Passage 1}+Max(T_{Passage 2}，T_{Identity authentication}，T_{Hazardous chemical collection}+T_{Hazardous chemical substance detection})+T_{Pass 3}. Because the collection and the detection of the dangerous chemicals are both carried out in the gate passage, the dangerous chemicals need to be detected after the collection of the dangerous chemicals is finished, and the total time T required by the dangerous chemicals and the detection of the dangerous chemicals is_{Hazardous chemical collection}+T_{Hazardous chemical substance detection}The time T that the personnel pass through the gate 12 is longer, the access voucher information acquisition and the dangerous chemical acquisition need to be carried out in sequence and not in parallel, the time of the access voucher information acquisition and the time of the dangerous chemical acquisition are in an addition relationship, and the time T that the personnel pass through the gate 12_{Passage 1}Nor is it utilized efficiently.

As described above, T of the present invention_{General assembly}Due to the parallel collection of the access voucher information and the dangerous chemicals, the parallel identification and the detection of the dangerous chemicals and the full utilization of the time T of the personnel passing through the gate 12_{The number of the passes 1 is the same as the number of the passes,}thus, T of the present invention_{General assembly}Must be less than T_{General assembly}' and T_{General assembly}”。

In other words, in the present embodiment, the entry/exit voucher information and the hazardous chemical are collected in parallel, the identification and the hazardous chemical detection are performed in parallel, and the identification and the hazardous chemical detection are started by the time when the person passes through the gate 12, so that the waiting time of the passers in the collection area can be reduced, and the total passing time through the gate system can be shortened.

After the step S111, the step S101 may be re-entered. That is, in the present invention, the transit time T for a passer to move from inside the gate 22 (i.e., inside the gate tunnel 30) to outside the gate 22 (i.e., outside the gate tunnel 30) is utilized_{Pass 3}The entrance voucher information collection of the step S103 and the dangerous chemical collection of the step S104 are performed for the next person who comes to the entrance of the entrance gate 10.

Specifically, for example, assuming that the i +1 th person has arrived at the entrance of the entrance gate 10 while the i-th person is passing through the exit gate 20, and there is no person passing through the gate 22 before the i-th person, and no person waiting outside the gate 12 after the i +1 th person, the total transit time T of the i-th person and the i + 1-th person_{General (i + (i +1))}Is composed of

T_{General (i + (i +1))}＝Max(T_{In-out voucher collection i},T_{Hazardous chemical Collection i})+Max(T_{Passage 1i}+T_{Passage 2i}，T_{Identity authentication i},T_{Hazardous chemical substance detection i})+Max(T_{Passage 3i}，T_{Collection of access voucher (i +1)},T_{Collection of hazardous chemicals i +1)})+Max(T_{Passage 1(i +1)}+T_{Passage 2(i +1)}，T_{Identity authentication (i +1)},T_{Hazardous chemical substance detection (i +1)})+T_{Passage 3(i +1)}

T_{General (i + (i +1))}＜2×T_{General assembly}

From this, as long as exit gate 22 is opened, just can carry out discrepancy voucher information collection and dangerous chemical collection to next passerby, the personnel in the back need not wait for preceding passerby to walk outside gate 22 completely, can further reduce passerby's latency, can shorten many people total transit time through the floodgate machine system in succession, improved the current efficiency of floodgate machine system. This effect is even more evident in the case of a large number of people queuing up to pass through the gate system continuously.

In step S112, the gate 22 of the gate 20 at the outlet is not opened, and an alarm is issued.

The manner of issuing the alarm may include: sending out alarm sound, calling management personnel, sending information to guard personnel or equipment and the like.

In step S113, after the passer-by passes through the entrance gate 10, the gate 12 is closed. That is, after the step S107 is performed, the pedestrian moves from outside the gate 12 (i.e., outside the gate tunnel 30) to inside the gate 12 (i.e., inside the gate tunnel 30), in other words, the elapsed passage time is set to T_{Passage 1}The shutter 12 is closed.

After the step S107 and before the step S113, i.e., after T is passed after the gate 12 of the entry gate 10 is opened_{Passage 1}After a passer-by enters gate 12, it may further include: and (5) carrying out trailing judgment. In the trailing determination step, the trailing detection device 17 is controlled to detect whether or not there is a trailing, and if there is no trailing, the process proceeds to step S113, and the gate 12 is normally closed. If a person trails, an alarm is given.

In addition, in step S114, after the pedestrian passes through the exit gate 20, the gate 22 thereof is closed. That is, after the step S111 is performed, the passer moves from inside the gate 22 (i.e., inside the gate passage 30) to outside the gate 12 (i.e., outside the gate passage 30), in other words, the elapsed passage time is set to T_{Pass 3}Then the shutter 22 is closed.

In the second embodiment, in the case where the gate system 200 has two gates, i.e., the entrance gate 12 and the exit gate 22, in the double gate structure, since both gates are closed when there is an abnormality as a result, it is possible to close a suspicious person in the gate passageway 30, and it is possible to more easily capture a suspicious person who carries flammable and explosive substances, drugs, toxic gases, etc., and threatens public safety.

As described above, in the second embodiment, the entry/exit voucher information and the hazardous chemical are collected in parallel, the identification and the hazardous chemical detection are performed in parallel, and the identification and the hazardous chemical detection are started when the user passes through the gate 12, whereby the waiting time of the passers-by in the collection area can be reduced and the total passing time through the gate system can be shortened while increasing the number of hazardous chemical collection and detection functions.

< third embodiment >

Hereinafter, specific examples of the third embodiment will be described with reference to fig. 14 to 15.

The third embodiment is different from the first and second embodiments in that, as shown in fig. 14, the gate system 300 includes, in addition to the same configuration as the gate systems 100 and 200: a bio-radar 70 and a health data analysis device 80. The control device 40 may also be connected to and control the bio-radar 70 and the health data analysis device 80. Fig. 14 to 15 illustrate the third embodiment as applied to the gate system of the double gate structure as the second embodiment, however, the third embodiment may be applied to the gate system of the single gate structure as the first embodiment.

The biological radar 70 scans the passer-by using radar waves to obtain health data of the passer-by. The health data includes: parameters of heartbeat, respiration, body movement, etc. For example, a heart rate indicating heart beat, a breathing rate indicating breathing, and the like.

As shown in fig. 14, the bio-radar may be installed inside the gate 22 (located in the gate tunnel 30) on the gate case 21 of the exit gate 20. Specifically, as shown in fig. 14, it may be disposed in front of the face recognition module 51 (in a direction close to the entrance gate).

The health data analysis device 80 can analyze health data of the operator and determine the health state of the operator. The health status may be a predetermined special health status.

In general, in the conventional technology, health data is obtained by directly detecting body temperature using a thermometer, an infrared thermometer, infrared thermography, or the like, and a person with an abnormal health state is prevented from entering or exiting a specific facility.

However, for example, in winter (or other cold weather), the body surface temperature of people is low, and the actual body temperature cannot be detected really, so that the misjudgment rate of people who are not healthy is high. If the body temperature rises, the metabolism is enhanced, the heart rate is accelerated, and the respiration is accelerated. In addition, the physical signs such as heartbeat and respiration are not affected by the weather temperature, so that the health state of the expert can be more accurately judged through the parameters.

In the present embodiment, since the biological radar 70 can obtain the health data such as heartbeat and respiration, the health data analysis device 80 can analyze the current accurate body temperature of the pedestrian based on the obtained data such as heartbeat and respiration.

Thus, in particular, the health data analysis device 80 may calculate the actual body temperature of the passer based on the heart rate, or may calculate the actual body temperature of the passer based on the breathing rate, or may calculate the actual body temperature of the passer based on both the heart rate and the breathing rate. When the calculated actual body temperature is higher than the predetermined temperature, it is considered that there is an abnormality in the health state, and when the actual body temperature is not higher than the predetermined temperature, it is considered that there is no abnormality in the health state.

In addition, the bio-radar 70 may also be used in combination with an infrared thermometry function. For example, when the face recognition module 51 further includes an infrared thermometry function, if the body temperature detected by the face recognition module 51 and the heartbeat detected by the biometric radar 70 do not match the corresponding relationship between the body temperature and the heartbeat in the normal state, the health state is considered to be abnormal. For example, if the body temperature detected by the face recognition module 51 is less than 36 °, but the heartbeat detected by the bio-radar 70 is greater than 90 times/min, it is considered that there is an abnormality.

The third embodiment is also different from the second embodiment in the processing executed by the control device 40.

Specifically, as shown in fig. 15, in addition to the processing shown in fig. 13 which is the same as the second embodiment, there are steps S115 and S116.

If it is determined in step S101 that a person is present in the collection area (step S101: YES), the process proceeds to step S115.

In step S115, it is determined whether or not a person has entered the scanning range of the biometric radar, and if the person has entered the scanning range of the biometric radar (yes in step S115), the process proceeds to step S116.

In step S116, a scan of the biological radar and an analysis of the health data are performed.

Specifically, while scanning partial data of a person to be passed with the bio-radar 70, a part of the health data obtained by the scanning may be transmitted to the health data analyzer 80, and the health data analyzer 80 may analyze the obtained partial data in real time to determine whether or not there is an abnormality.

After the scanning and analysis in step S116, the process proceeds to step S110, where it is determined whether or not there is any abnormality in the authentication result of the authentication device 50, the detection result of the hazardous chemical detection device 60, or the analysis result of the health data analysis device 80.

As described above, according to the third embodiment, while performing authentication and dangerous chemical detection, the health status of the passers can be detected, and not only suspicious persons carrying dangerous chemicals can be excluded, but also persons with abnormal health status, such as persons carrying infectious diseases, can be simultaneously checked to enter and exit a specific facility, so that the checking function of the gate system can be increased. In addition, because the health state detection, the information collection and verification of the access voucher and the collection and detection of dangerous chemicals are executed in parallel, the functions can be added, and meanwhile, the total passing time of the gate system cannot be increased.

In addition, in the present embodiment, by measuring objective and accurate health data using the bio-radar, it is possible to avoid erroneous determination due to environmental conditions such as low temperature, and to improve the accuracy of health status investigation.

< fourth embodiment >

Hereinafter, specific examples of the third embodiment will be described with reference to fig. 16 to 18.

The fourth embodiment is different from the first, second, and third embodiments in that, as shown in fig. 16 and 17, the gate system 300 includes, in addition to the same configuration as the gate systems 100 and 200: a radioactive substance detection device 90. The control device 40 may be connected to the radioactive substance detection device 90 and may control the same. Fig. 16 to 18 illustrate the fourth embodiment applied to the gate system of the double gate structure as the second embodiment, however, the fourth embodiment may be applied to the gate system of the single gate structure as the first embodiment.

The radioactive substance detection device 90 can receive radiation emitted from the radioactive substance, such as α -rays, β -rays, γ -rays, and X-rays. The radioactive substance detection device 90 also analyzes the received radiation, and determines whether or not the person in transit carries the radioactive substance. The presence of an abnormality may be determined when a predetermined amount or more of rays is detected, and otherwise, the absence of an abnormality may be determined.

As shown in fig. 16, two radioactive material detection apparatuses 90 may be installed at both sides of the gate passage 30. As shown in fig. 17, the two radioactive material detection devices 90 may be mounted at diagonally opposite positions of the gate enclosure 11 and the gate enclosure 21, respectively. For example, the corner of the left side gate chassis 11 inside the gate passage 30 and the corner of the right side gate chassis 21 inside the gate passage 30 are installed to face each other. The corner inside the gate passage 30 of the right gate casing 11 and the corner inside the gate passage 30 of the left gate casing 21 may be installed to face each other.

The fourth embodiment is also different from the second embodiment in the processing executed by the control device 40.

Specifically, as shown in fig. 18, in addition to the processing shown in fig. 12 which is the same as the second embodiment, there is a step S117.

In step S107, after the gate 12 of the entry gate 10 is opened, the process also proceeds to step S117. That is, the pedestrian enters the gate passage 30 through the gate 12 and enters the detection range of the radioactive substance detection device 90.

In step S117, the radioactive material is detected, and it is determined whether or not the pedestrian carries the radioactive material, and if so, if an abnormality is present, the determination is no in step S110, and the process proceeds to step S112. If it is judged that the passer-by has not carried radioactive substances, the step is no abnormality, and if the identity authentication in step S108 and the detection of dangerous chemicals in step S109 are both no abnormality (step S110: yes), the routine proceeds to step S111.

In step S117, specifically, the radiation received by the detector of the radioactive substance detection apparatus 90 may be analyzed while receiving the radiation, and when the radiation is detected to be a predetermined amount or more, it may be determined that there is an abnormality, or otherwise, it may be determined that there is no abnormality.

As described above, according to the third embodiment, it is possible to detect whether or not a person in charge carries a radioactive substance while performing authentication and dangerous chemical detection, and it is possible to add a check function of a gate system. In addition, since the radioactive substance detection, the identity authentication and the dangerous chemical detection are performed in parallel, the total passing time of the gate system can not be increased while the functions are added.

As shown in fig. 19, the second, third, and fourth embodiments may be combined with each other, that is, hazardous chemical detection, health status check, and radioactive substance detection are performed simultaneously.

Although the embodiments of the gate system and the control method have been described above, the present invention can be realized as a program for executing the control method and a storage medium storing the program.
