Description

Technical Field

[0001] The present invention relates to a gate device having a gate capable of opening and closing a passage.

Background Art

[0002] Conventionally, many gate devices such as automatic ticket gates include a passage sensor composed of a photoelectric sensor including a plurality of light emitting elements and light receiving elements arranged along the passage direction of the passage, and this passage sensor detects a person trying to pass through the passage (hereinafter referred to as "passenger") (see Patent Document 1 etc.). When this type of device determines that so-called "tailgating" has occurred based on the detection result of the passage sensor, it is often configured to close the gate and prevent passage through the passage.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the aforementioned passage sensors may misdetect the luggage carried by a pedestrian as a person (i.e., a different pedestrian) if the pedestrian is carrying luggage such as a suitcase, meaning the pedestrian and luggage are moving separately. Such misdetections are undesirable because they can lead to the gate device misidentifying "tailgating" and unnecessarily closing off passages, potentially hindering smooth passage. As a countermeasure, it is conceivable to add a configuration to the gate device that detects luggage using cameras or 3D sensors. However, since cameras and 3D sensors need to be installed at relatively high positions, the space required to install the gate device (i.e., installation space) increases, limiting the installation location of the gate device. Furthermore, it would lead to increased system complexity, such as the need to add a dedicated processing unit.

[0005] Therefore, the present invention aims to provide a gate device that can prevent the misidentification of luggage carried by passersby as people, while suppressing an increase in installation space and complexity of the system configuration, thereby reducing the unnecessary closure of passageways by the gate. [Means for solving the problem]

[0006] According to one aspect of the present invention, a gate device is provided. This gate device is positioned to the side of a passageway, Information reading unit that reads the information on the toll ticket, The device body includes a gate that opens and closes the passage at the exit side of the passage, a position sensor that detects the position of an object passing through the passage, a temperature sensor that detects the temperature of the object, and a height sensor that detects the height of the object. The system includes a control unit that operates the gate based on the pass information read by the information reading unit and the detection signals from the position sensor, the temperature sensor, and the height sensor. Based on the detection signal from the position sensor, it is determined that an object has entered the passage. Based on the detection signals from the temperature sensor and the height sensor, it is identified whether the object that entered the passage is a person or luggage. If the object is a person, the gate is closed. And, before The control unit is a person. The aforementioned Following the object Following If the object enters the passage, FollowingIf the object is luggage, then Following The gate is closed after waiting for the object to pass through the gate, Following If the object is a person Preceding When the object, which is a person, passes through the gate In order to prevent the subsequent object from passing The gate is closed immediately. [Effects of the Invention]

[Figure 7] This flowchart shows an example of processing by the control unit of the gate device according to the embodiment. [Modes for carrying out the invention]

[0009] Hereinafter, embodiments of the present invention will be described based on the attached drawings.

[0010] Figure 1 is a diagram showing the external configuration of a gate device 1 according to one embodiment of the present invention, and Figure 2 is a block diagram showing the control system configuration of the gate device 1. The gate device 1 according to this embodiment includes a device body 3 and a control unit 5 that controls the overall operation of the device body 3.

[0011] The main body of the device 3 is positioned adjacent to the passage T, to the side of the passage T. The main body of the device 3 includes an information reading unit 31, a gate 32, a position sensor 33, a temperature sensor 34, a height sensor 35, and a notification unit 36.

[0012] The information reading unit 31 is located on the side closest to a pedestrian approaching the passage T, that is, on the entrance side of the passage T in the main body of the device 3. The information reading unit 31 is configured to read the passage ticket information recorded on the passage ticket medium when, for example, a pedestrian holds their passage ticket medium over the information reading unit 31. The read passage ticket information is output to the control unit 5. The passage ticket information is the information necessary to pass through the passage T. In other words, a pedestrian intending to pass through the passage T can do so by holding a passage ticket medium with the correct (or valid) passage ticket information recorded on it over the information reading unit 31. The passage ticket medium is various types of medium capable of recording the passage ticket information, including admission ticket mediums, passenger ticket mediums, and boarding ticket mediums.

[0013] Furthermore, the information reading unit 31 may be configured as an information reading / writing unit capable of not only reading the toll ticket information recorded on the toll ticket medium, but also writing information to the toll ticket medium.

[0014] The gate 32 is provided at the back side as viewed from a passerby moving toward the passage T, that is, at the exit side of the passage T in the apparatus main body 3. The gate 32 is configured to open and close the passage T by rotation. Specifically, one end side of the gate 32 is rotatably supported by the apparatus main body 3, and it is configured to rotate between a first posture (the state shown by the dashed line in FIG. 1) substantially parallel to the surface of the apparatus main body 3 on the passage T side and a second posture (the state shown by the solid line in FIG. 1) substantially perpendicular to the surface of the apparatus main body 3 on the passage T side. And the gate 32 is configured to open the passage T when in the first posture and allow a passerby to pass through the passage T in the arrow direction, and to close the passage T when in the second posture and prevent a passerby from passing through the passage T in the arrow direction. The gate 32 is operated by the control unit 5.

[0015] In the present embodiment, the normal posture of the gate 32 is the second posture. That is, the gate 32 is normally in a state of closing the passage T and preventing a passerby from passing through the passage T in the arrow direction. In the following description, changing the posture (rotation) of the gate 32 in the first posture to the second posture, that is, operating the gate 32 to close the passage T, is referred to as "closing operation of the gate 3"2. Also, changing the posture (rotation) of the gate 32 in the second posture to the first posture, that is, operating the gate 32 to open the passage T, is referred to as "opening operation of the gate 32".

[0016] The position sensor 33 detects the position of an object passing through the passage T. More specifically, the position sensor 33 is configured to be able to detect the entry of an object into the passage T, the position of the object in the passage T, and the exit of the object from the passage T. Although not particularly limited, in the present embodiment, the position sensor 33 is composed of two sets of transmissive photoelectric sensors, and has an upper light receiving part 33a and a lower light receiving part 33b installed in two upper and lower stages on the surface of the apparatus main body 3 on the passage T side, and an upper light projecting part and a lower light projecting part (both not shown) facing these across the passage T.

[0017] The upper light-receiving part 33a includes a plurality of light-receiving elements arranged along the passage T, and the upper light-projecting part includes a plurality of light-projecting elements arranged to face the plurality of light-receiving elements of the upper light-receiving part 33a with the passage T interposed therebetween. Further, the lower light-receiving part 33b includes a plurality of light-receiving elements arranged along the passage T, and the lower light-projecting part includes a plurality of light-projecting elements arranged to face the plurality of light-receiving elements of the lower light-receiving part 33b with the passage T interposed therebetween.

[0018] And the position sensor 33 is configured to detect the presence and position of an object in the passage T when the light-receiving elements of the upper light-receiving part 33a do not receive light from the corresponding light-projecting elements of the upper light-projecting part and / or when the light-receiving elements of the lower light-receiving part 33b do not receive light from the corresponding light-projecting elements of the lower light-projecting part, that is, when the light from the upper light-projecting part and / or the lower light-projecting part is blocked by an object. The signal (detection signal) of the position sensor 33 is output to the control unit 5.

[0019] Here, a set of transmissive photoelectric sensors (one position sensor) is constituted by the upper light-receiving part 33a and the upper light-projecting part, and another set of transmissive photoelectric sensors (another position sensor) is constituted by the lower light-receiving part 33b and the lower light-projecting part. Also, in the present embodiment, the upper light-receiving part 33a and the upper light-projecting part are arranged above by the intermediate position in the height direction of the apparatus main body 3, and the lower light-receiving part 33b and the lower light-projecting part are arranged below the intermediate position. Therefore, it can also be said that the position sensor 33 is constituted by an upper position sensor 33U that detects the position of an object passing through the passage T above the intermediate position and a lower position sensor 33L that detects the position of an object passing through the passage T below the intermediate position.

[0020] The temperature sensor 34 detects the temperature (surface temperature) of an object passing through the passage T. Although not particularly limited, in this embodiment, the temperature sensor 34 is configured as a radiation thermometer capable of measuring the temperature of an object non-contact. The temperature sensor 34, like the position sensor 33, is located on the passage T-side surface of the device body 3. Specifically, in this embodiment, the temperature sensor 34 is located on the entrance side of the center of the passage T, and in the height direction, it is located between the upper position sensor 33U and the lower position sensor 33L that constitute the position sensor 33. The signal (detection signal) from the temperature sensor 34 is output to the control unit 5. The temperature sensor 34 can also detect the temperature of an object that has entered the passage T.

[0021] The height sensor 35 detects the height of an object passing through the passage T. Specifically, in this embodiment, the height sensor 35 detects whether an object passing through the passage T has a height equal to or greater than a predetermined height (hereinafter referred to as the "height threshold"). The height threshold is not particularly limited, but can be set at any height between 1.0m and 1.5m from the road surface of the passage T. Also, not particularly limited, in this embodiment, the height sensor 35 is composed of a reflective photoelectric sensor including a light-emitting unit and a light-receiving unit. The height sensor 35 is located on the passage T side of the device body 3, similar to the position sensor 33 and the temperature sensor 34. Specifically, in this embodiment, the height sensor 35 is located on the entrance side of the center of the passage T and near the top of the device body 3 (above the position sensor 33). The signal (detection signal) from the height sensor 35 is output to the control unit 5. The height sensor 35 can also detect the height of an object that has entered the passage T. Furthermore, the height sensor 35 may be composed of a transmissive photoelectric sensor, similar to the position sensor 33.

[0022] Here, although not shown in the figure, the gate device 1 may have another device body that is paired with the device body 3. The other device body is positioned opposite the device body 3 across the passage T. In this case, the other device body may have another gate that is paired with gate 32 and interlocks with gate 32. Furthermore, the upper light-emitting unit and the lower light-emitting unit may be installed in two stages, upper and lower, on the passage T-side surface of the other device body. In addition, another temperature sensor paired with temperature sensor 34, and / or another height sensor paired with height sensor 35 may be installed on the passage T-side surface of the other device body.

[0023] The notification unit 36 ​​is provided at any part of the main body 3 of the device. The notification unit 36 ​​is mainly provided to notify passersby and staff when it is necessary to prevent them from passing through the passage T. The notification unit 36 ​​may include, but is not limited to, a light-emitting unit that emits notification light, a sound-generating unit that generates notification sound, and / or a display unit that displays notification information. The operation of the notification unit 36 ​​is controlled by the control unit 5.

[0024] The control unit 5 is located inside the main body 3 of the device. The control unit 5 receives the pass information read by the information reading unit 31, the detection signal from the position sensor 33, the detection signal from the temperature sensor 34, and the detection signal from the height sensor 35. Based on the input pass information and the detection signals from each sensor, the control unit 5 is configured to control the opening and closing of the gate 32 and the operation of the notification unit 36.

[0025] Next, we will specifically explain the processing performed by the control unit 5 (in other words, the operation of the gate device 1). Figures 3 to 6 are flowcharts showing an example of the processing performed by the control unit 5.

[0026] In step S1 of Figure 3, the control unit 5 awaits input of the toll ticket information. In other words, the gate device 1 waits for the information reading unit 31 to read the toll ticket information recorded on the toll ticket medium.

[0027] In step S2, the control unit 5 determines whether an object has entered the passage T. This determination is made based on the detection signal of the position sensor 33. When the object has entered the passage T (step S2: YES), the control unit 5 proceeds to the process of step S8 (Fig. 5). On the other hand, when the object has not entered the passage T (step S2: NO), the control unit 5 proceeds to the process of step S3.

[0028] In step S3, the control unit 5 determines whether the pass information has been input. When the pass information has been input (step S3: YES), the control unit 5 proceeds to the process of step S4. On the other hand, when the pass information has not been input (step S3: NO), the control unit 5 returns to step S1 and maintains the waiting state for the input of the pass information.

[0029] In step S4, the control unit 5 determines whether the pass information input in step S3 is appropriate (valid). When the pass information is appropriate (valid) (step S4: YES), the control unit 5 proceeds to the process of step S5. On the other hand, when the pass information is not appropriate (valid), passage of the passage T by the passerby is not permitted. Therefore, when the pass information is not appropriate (valid) (step S4: NO), the control unit 5 proceeds to the process of step S31 (Fig. 6), activates the notification unit 36, and then continues to activate the notification unit 36 until a release operation is performed by a staff member or the like (steps S31 to S33).

[0030] In step S5, the control unit 5 increments the number of passage rights. Specifically, the control unit 5 changes the number of passage rights from "0" to "+1". The number of passage rights corresponds to the number of passersby (persons) permitted to pass through the passage T.

[0031] In step S6, the control unit 5 opens the gate 32. As a result, the passage T is opened, and it becomes possible for the passerby to pass through the passage T in the arrow direction.

[0032] In step S7, the control unit 5 determines, similar to step S2, whether or not the object has entered the passage T. If the object has entered the passage T, the control unit 5 proceeds to the process in step S12.

[0033] If the process in step S2 described above determines that an object has entered passage T, in step S8 (Figure 5), the control unit 5 determines whether or not the toll ticket information has been entered, similar to step S3. If the toll ticket information has been entered (step S8: YES), the control unit 5 proceeds to the process in step S9. On the other hand, if the toll ticket information has not been entered (step S8: NO), the control unit 5 proceeds to the process in step S12.

[0034] In step S9, it is determined whether the toll ticket information entered in step S8 is valid or not. If the toll ticket information is valid (step S9: YES), the control unit 5 proceeds to the process in step S10. On the other hand, if the toll ticket information is not valid (step S9: NO), the control unit 5 proceeds to the process in step S31 (Figure 6), activates the notification unit 36, and continues to operate the notification unit 36 ​​until it is deactivated by an attendant or the like (steps S31 to S33).

[0035] In step S10, the control unit 5 increments the number of passage rights, and in step S11, the control unit 5 opens the gate 32. After the control unit 5 opens the gate 32 in step S11, it proceeds to the process in step S12. Note that the processes in steps S8 to S11 are basically the same as the processes in steps S3 to S6.

[0036] In step S12, the control unit 5 performs an identification process for the object that has entered the passage T. Specifically, in this embodiment, the control unit 5 identifies whether the object that has entered the passage T is a person or luggage.

[0037] Figure 7 is a flowchart showing an example of the object identification process in step S12. In step S121 of Figure 7, the control unit 5 determines whether the height of the object entering the passage T is equal to or greater than the height threshold. This determination is made based on the detection signal from the height sensor 35. If the height of the object entering the passage T is less than the height threshold (step S121: NO), the control unit 5 proceeds to the process in step S122. On the other hand, if the height of the object entering the passage T is equal to or greater than the height threshold (step S121: YES), the control unit 5 proceeds to the process in step S123.

[0038] In step S122, the control unit 5 determines whether the temperature (surface temperature) of the object that has entered the passage T is within the set temperature range. This determination is made based on the detection signal from the temperature sensor 34. The set temperature range is a temperature range that corresponds to the surface temperature (on clothing) of a typical person. Although not particularly limited, the set temperature range may be, for example, 30 to 45°C. If the temperature of the object that has entered the passage T is within the set temperature range (step S122: YES), the control unit 5 proceeds to the process in step S124. On the other hand, if the temperature of the object that has entered the passage T is outside the set temperature range (step S122: NO), the control unit 5 proceeds to the process in step S125.

[0039] In step S123, the control unit 5 identifies the object that has entered the passage T as a person (i.e., a passerby), more specifically, an adult passerby. In step S124, the control unit 5 identifies the object that has entered the passage T as a person (passerby), more specifically, a child passerby. In step S125, the control unit 5 identifies the object that has entered the passage T as luggage. In other words, in this embodiment, if the height of the object that has entered the passage T is greater than or equal to the height threshold, or if the height of the object that has entered the passage T is less than the height threshold and the temperature of the object that has entered the passage T is within the set temperature range, the control unit 5 identifies the object as a person (passerby), and if the height of the object that has entered the passage T is less than the height threshold and the temperature of the object that has entered the passage T is outside the set temperature range, the control unit 5 identifies the object as luggage carried by a person (passerby).

[0040] Returning to Figure 3, in step S13, the control unit 5 associates the object that entered the passage T with the identification result from step S12. This allows the control unit 5 to recognize whether the object that entered the passage T (=object moving within the passage T) is a person (pedestrian) or luggage.

[0041] In step S14, the control unit 5 determines whether another object has entered the passage T following the first object. If another object has entered the passage T (step S14: YES), the control unit 5 proceeds to step S15. On the other hand, if another object has not entered the passage T (step S14: NO), the control unit 5 proceeds to step S17 (Figure 4).

[0042] In step S15, the control unit 5 performs an identification process for another object that has entered the passage T. This identification process is basically the same as the object identification process in step S12, and the control unit 5 identifies whether the other object that has entered the passage T is a person or luggage (see Figure 7).

[0043] In step S16, the control unit 5 associates the identification result from step S15 with another object that has entered the passage T. This allows the control unit 5 to recognize whether the other object that entered the passage T after the aforementioned object (i.e., another object moving within the passage T) is a person (pedestrian) or luggage.

[0044] In step S17 (Figure 4), the control unit 5 determines, based on the results of the linking in steps S13 and S16 and the detection signal from the position sensor 33, whether or not the object recognized as a person (hereinafter simply referred to as "person") has reached the center of the passage T. If the person has reached the center of the passage T, the control unit 5 proceeds to the process in step S18.

[0045] In step S18, the control unit 5 determines whether the number of passage rights is 1 or more. If the number of passage rights is less than 1 (i.e., 0), the person who reached the center of passage T is considered to be a person who entered passage T without holding up a passage ticket medium with the correct passage ticket information recorded on the information reading unit 31, that is, a person who is not permitted to pass through passage T. Therefore, if the number of passage rights is less than 1 (i.e., 0) (step S18: NO), the control unit 5 proceeds to the process in step S31 (Figure 6), activates the notification unit 36, and continues to operate the notification unit 36 ​​until it is deactivated by an attendant or the like (steps S31 to S33).

[0046] On the other hand, if the number of passage rights is 1 or more, the person who reaches the center of passage T is considered to be the person who entered passage T after holding a passage ticket medium with the correct passage ticket information recorded on it over the information reading unit 31, that is, the person who was permitted to pass through passage T. Therefore, if the number of passage rights is 1 or more (step S18: YES), the control unit 5 proceeds directly to the processing in step S19.

[0047] In step S19, the control unit 5 determines whether the person who reached the center of the passage T subsequently passed through gate 32. This determination is made based on the detection signal from the position sensor 33. If the person passes through gate 32, the control unit 5 proceeds to the process in step S20. Alternatively, the control unit 5 may determine whether the person has left passage T instead of determining whether the person has passed through gate 32.

[0048] In step S20, the control unit 5 decrements the number of right-of-way. Specifically, the control unit 5 changes the number of right-of-way from "1" to "0".

[0049] In step S21, the control unit 5 determines whether or not there is an object following the person who has passed through gate 32 (a subsequent object). If a subsequent object exists (step S21: YES), the control unit 5 proceeds to step S22. On the other hand, if no subsequent object exists (step S21: NO), the control unit 5 proceeds to step S24 and closes gate 32.

[0050] In step S22, the control unit 5 determines whether the following object is luggage. This determination is mainly based on the results of the identification process in step S12 and / or step S15. If the following object is luggage, it is considered to be luggage carried by the person who passed through gate 32. Therefore, the gate 32 must be closed after waiting for the object (luggage) to pass through gate 32. For this reason, if the following object is luggage (step S22: YES), the control unit 5 proceeds to step S23 to determine whether the following object (i.e., luggage) has passed through gate 32, and if the following object (luggage) has passed through gate 32, it proceeds to step S24 to close gate 32.

[0051] On the other hand, if the following object is not cargo, that is, if the following object is a person, then the following object is considered to be a person who is not permitted to pass through passage T (the number of passage rights has already become 0). Therefore, if the following object is not cargo (step S22: NO), the control unit 5 proceeds to step S24 and quickly closes the gate 32 in order to prevent the following object (person) from passing, that is, to prevent a person who is not permitted to pass through passage T from passing through passage T in a tailgating manner.

[0052] As described above, the gate device 1 according to this embodiment includes a device body 3 arranged adjacent to the passage T on the side of the passage T, and a control unit 5 that controls the overall operation of the device body 3. The device body 3 has an information reading unit 31, a gate 32, a position sensor 33, a temperature sensor 34, and a height sensor 35. The control unit 5 is configured to open and close the gate 32 based on the passage ticket information read by the information reading unit 31 and the detection signals from the position sensor 33, the temperature sensor 34, and the height sensor 35.

[0053] Specifically, the control unit 5 opens the gate 32 if the pass information read by the information reading unit 31 is correct (see steps S3-S6 in Figure 3 and steps S8-S11 in Figure 5), opening the passage T so that people can pass through. Furthermore, when the control unit 5 detects that an object has entered the passage T based on the detection signal from the position sensor 33, it identifies whether the object that entered the passage T is a person (person) or luggage based on the detection signals from the temperature sensor 34 and the height sensor 35 (see steps S12, S15 in Figure 3 and Figure 6). The control unit 5 then reflects the identification result of whether the object that entered the passage T is a person (person) or luggage in the operation of the gate 32 (especially the closing operation). In other words, the control unit 5 closes the gate 32 after recognizing whether each object moving within the passage T is a person or luggage (see steps S12-S16 in Figure 3 and steps S17-S24 in Figure 4).

[0054] Therefore, according to the gate device 1 of this embodiment, misidentification of luggage carried by a passerby as a person (another passerby) is prevented, and unnecessary closure of the passage T by the gate 32 is reduced. Furthermore, the temperature sensor 34 and height sensor 35 used to identify whether an object entering the passage T is a person (passerby) or luggage can be installed on the device body 3, more specifically, on the passage T-side surface of the device body 3. Thus, the installation space for the gate device 1 does not increase, and the gate device 1 can be installed in the space where conventional devices of the same type were installed. Moreover, when the control unit 5 identifies whether an object entering the passage T is a person (passerby) or luggage, it only needs to determine whether the height of the object entering the passage T is above the height threshold and whether the (surface) temperature of the object entering the passage T is within the set temperature range, and complex processing is not required. Thus, the complexity of the system configuration can also be suppressed.

[0055] Furthermore, the control unit 5 identifies whether an object entering the passage T is an adult pedestrian, a child pedestrian, or luggage, based on the detection signals from the temperature sensor 34 and the height sensor 35. Therefore, the control unit 5 can perform different processing depending on whether the pedestrian is an adult or a child. For example, if the object is a child pedestrian, the control unit 5 can treat the object (child) as luggage and process it accordingly.

[0056] In the above-described embodiment, the information reading unit 31 is configured to read the toll ticket information from the toll ticket medium held over itself. However, it is not limited to this. The information reading unit 31 may also be configured to read the toll ticket information recorded on the toll ticket medium of a passerby approaching it.

[0057] Furthermore, in the above-described embodiment, the control unit 5 identifies an object (that has entered the passage T) as an adult pedestrian if its height is equal to or greater than the height threshold, as a child pedestrian if its height is less than the height threshold and its temperature is within the set temperature range, and as luggage if its height is less than the height threshold and its temperature is outside the set temperature range. However, it is not limited to this. The control unit 5 may also identify an object as an adult pedestrian if its height is equal to or greater than the height threshold and its temperature is within the set temperature range, as a child pedestrian if its height is less than the height threshold and its temperature is within the set temperature range, and as luggage if its temperature is outside the set temperature range.

[0058] Although embodiments and variations thereof of the present invention have been described above, the present invention is not limited to the embodiments and variations described above, and further modifications and changes are possible based on the technical concept of the present invention.
