Description

This invention relates to a gate device having a gate capable of opening and closing a passageway.

Conventionally, many gate devices, such as automatic ticket gates, include a passage sensor consisting of a photoelectric sensor with multiple light-emitting and light-receiving elements arranged along the direction of passage. This passage sensor detects a person attempting to pass through the passage (hereinafter referred to as "passenger") (see Patent Document 1, etc.). This type of device is often configured to close the gate and prevent passage through the passage if it determines, based on the detection results of the passage sensor, that so-called "tailgating" has occurred.

Japanese Patent Publication No. 2001-216540

However, the aforementioned passage sensors may misdetect a person (i.e., another person) when a 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 incorrect "tailgating" detection by the gate device and unnecessary closure of passageways, potentially hindering smooth passage. As a countermeasure, adding a configuration to the gate device that detects luggage using cameras or 3D sensors could be considered. However, cameras and 3D sensors need to be installed at relatively high positions, increasing the space required for gate device installation (i.e., installation space) and limiting the location of the gate device. Furthermore, it would complicate the system configuration by requiring the addition of dedicated processing units.

Therefore, the present invention aims to provide a gate device that prevents the misidentification of luggage carried by passersby as people, while suppressing an increase in installation space and complexity of the system configuration, thereby reducing unnecessary closure of passageways by the gate.

According to one aspect of the present invention, a gate device is provided. This gate device includes a device body positioned to the side of a passageway and having an information reading unit for reading pass information, a gate for opening and closing the passageway on the exit side of the passageway, a position sensor for detecting the position of an object passing through the passageway, a temperature sensor for detecting the temperature of the object, and a height sensor for detecting the height of the object, and a control unit for operating 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. The control unit determines that an object has entered the passage based on the detection signal from the position sensor, identifies whether the object that entered the passage is a person or luggage based on the detection signals from the temperature sensor and the height sensor, closes the gate when the object is a person passes through the gate , and if a subsequent object enters the passage following the person, the control unit closes the gate after waiting for the subsequent object to pass through if the subsequent object is luggage, and closes the gate after the preceding person has passed through the gate to prevent the subsequent object from passing through if the subsequent object is a person.

According to the present invention, it is possible to provide a gate device that prevents the misidentification of luggage carried by passersby as people, while suppressing an increase in installation space and complexity of the system configuration, thereby reducing unnecessary closure of passageways by the gate.

The embodiments of the present invention will be described below with reference to the attached drawings.

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.

The main unit 3 is positioned adjacent to the passage T, to the side of the passage T. The main unit 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.

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 within 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. This passage ticket information is necessary for passing through passage T. In other words, a pedestrian intending to pass through passage T can do so by holding a passage ticket medium containing the correct (or valid) passage ticket information 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, train ticket mediums, and boarding ticket mediums.

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.

The gate 32 is located on the far side of the passage T from the perspective of a passerby approaching the passage T, that is, on the exit side of the passage T within the device body 3. The gate 32 is configured to open and close the passage T by rotation. Specifically, one end of the gate 32 is rotatably supported by the device body 3, and it is configured to rotate between a first position (shown by a dashed line in Figure 1) where the gate 32 is approximately parallel to the passage T-side surface of the device body 3, and a second position (shown by a solid line in Figure 1) where the gate 32 is approximately perpendicular to the passage T-side surface of the device body 3. The gate 32 is configured to open the passage T when in the first position, allowing passersby to pass through the passage T in the direction of the arrow, and to close the passage T when in the second position, preventing passersby from passing through the passage T in the direction of the arrow. The gate 32 is operated by the control unit 5.

In this embodiment, the normal position of the gate 32 is the second position. That is, the gate 32 is normally in a state where it closes the passage T, preventing pedestrians from passing through the passage T in the direction of the arrow. In the following description, changing the position (rotating) of the gate 32 from the first position to the second position, that is, operating the gate 32 to close the passage T, is referred to as "closing the gate 32." Conversely, changing the position (rotating) of the gate 32 from the second position to the first position, that is, operating the gate 32 to open the passage T, is referred to as "opening the gate 32."

The position sensor 33 detects the position of an object moving through the passage T. More specifically, the position sensor 33 is configured to detect the entry of an object into the passage T, the position of an object within the passage T, and the exit of an object from the passage T. While not particularly limited, in this embodiment, the position sensor 33 is composed of two sets of transmissive photoelectric sensors, comprising an upper light-receiving unit 33a and a lower light-receiving unit 33b installed in two upper and lower stages on the passage T-side surface of the device body 3, and an upper light-emitting unit and a lower light-emitting unit (both not shown) facing these on either side of the passage T.

The upper light-receiving section 33a includes a plurality of light-receiving elements arranged along the passage T, and the upper light-emitting section includes a plurality of light-emitting elements arranged opposite to the plurality of light-receiving elements of the upper light-receiving section 33a across the passage T. Furthermore, the lower light-receiving section 33b includes a plurality of light-receiving elements arranged along the passage T, and the lower light-emitting section includes a plurality of light-emitting elements arranged opposite to the plurality of light-receiving elements of the lower light-receiving section 33b across the passage T.

The position sensor 33 is configured to detect the presence and position of an object in the passage T when the light-receiving element of the upper light-receiving unit 33a does not receive light from the corresponding light-emitting element of the upper light-emitting unit, and/or when the light-receiving element of the lower light-receiving unit 33b does not receive light from the corresponding light-emitting element of the lower light-emitting unit. In other words, when the light from the upper light-emitting unit and/or the lower light-emitting unit is blocked by an object. The signal (detection signal) from the position sensor 33 is output to the control unit 5.

Here, the upper light-receiving unit 33a and the upper light-emitting unit constitute one pair of transmissive photoelectric sensors (one position sensor), and the lower light-receiving unit 33b and the lower light-emitting unit constitute another pair of transmissive photoelectric sensors (another position sensor). Furthermore, in this embodiment, the upper light-receiving unit 33a and the upper light-emitting unit are positioned above the intermediate height of the device body 3, while the lower light-receiving unit 33b and the lower light-emitting unit are positioned below the intermediate height. Therefore, the position sensor 33 can also be said to consist of an upper position sensor 33U that detects the position of an object passing through the passage T above the intermediate height, and a lower position sensor 33L that detects the position of an object passing through the passage T below the intermediate height.

The temperature sensor 34 detects the temperature (surface temperature) of objects passing through the passage T. While not particularly limited, in this embodiment, the temperature sensor 34 is configured as a radiation thermometer capable of non-contact measurement of the object's temperature. The temperature sensor 34, like the position sensor 33, is positioned on the passage T-facing side of the device body 3. Specifically, in this embodiment, the temperature sensor 34 is located on the entrance side of the passage T's center in the passage direction, and in the height direction, it is positioned 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 objects entering the passage T.

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"). Although not particularly limited, the height threshold can be set at any height between 1.0 m and 1.5 m from the road surface of the passage T. Also, although 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 surface 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 in the passage direction, 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 configured as a transmissive photoelectric sensor, similar to the position sensor 33.

Here, although not shown in the figure, the gate device 1 may have another device body paired with the device body 3. This 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 paired with gate 32 and that interlocks with gate 32. Furthermore, the upper and lower light-emitting units may be installed in two tiers, upper and lower, on the passage T-side surface of the other device body. Additionally, 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.

The notification unit 36 is provided at any part of the main body 3 of the device. The notification unit 36 is primarily provided to notify pedestrians and staff when their passage through the passage T is being blocked. While not particularly limited, the notification unit 36 may include 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.

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.

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 illustrating an example of the processing performed by the control unit 5.

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.

In step S2, the control unit 5 determines whether or not the object has entered the passage T. This determination is made based on the detection signal from the position sensor 33. If the object has entered the passage T (step S2: YES), the control unit 5 proceeds to step S8 (Figure 5). On the other hand, if the object has not entered the passage T (step S2: NO), the control unit 5 proceeds to step S3.

In step S3, the control unit 5 determines whether or not the toll ticket information has been entered. If the toll ticket information has been entered (step S3: YES), the control unit 5 proceeds to the process in step S4. On the other hand, if the toll ticket information has not been entered (step S3: NO), the control unit 5 returns to step S1 and maintains a waiting state for the input of the toll ticket information.

In step S4, the control unit 5 determines whether the toll ticket information entered in step S3 is valid or incorrect. If the toll ticket information is valid (step S4: YES), the control unit 5 proceeds to step S5. On the other hand, if the toll ticket information is incorrect or incorrect, the user is not permitted to pass through passage T. Therefore, if the toll ticket information is incorrect or incorrect (step S4: NO), the control unit 5 proceeds to 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 other authorized person (steps S31-S33).

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 people (passengers) permitted to pass through passage T.

In step S6, the control unit 5 opens the gate 32. This opens the passage T, allowing pedestrians to pass through the passage T in the direction of the arrow.

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.

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

In step S9, the control unit 5 determines whether the toll ticket information entered in step S8 is valid or incorrect. If the toll ticket information is valid (step S9: YES), the control unit 5 proceeds to step S10. On the other hand, if the toll ticket information is incorrect (step S9: NO), the control unit 5 proceeds to 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 other person (steps S31 to S33).

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 opening the gate 32 in step S11, the control unit 5 proceeds to step S12. Note that the processes in steps S8 to S11 are basically the same as those in steps S3 to S6.

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.

Figure 7 is a flowchart illustrating 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 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 step S123.

In step S122, the control unit 5 determines whether the temperature (surface temperature) of the object entering 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 corresponding to the surface temperature of a typical person (on clothing). While not particularly limited, the set temperature range could be, for example, 30 to 45°C. If the temperature of the object entering the passage T is within the set temperature range (step S122: YES), the control unit 5 proceeds to step S124. On the other hand, if the temperature of the object entering the passage T is outside the set temperature range (step S122: NO), the control unit 5 proceeds to step S125.

In step S123, the control unit 5 identifies the object entering 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 entering the passage T as a person (passerby), more specifically, a child passerby. In step S125, the control unit 5 identifies the object entering the passage T as luggage. In other words, in this embodiment, if the height of the object entering the passage T is greater than or equal to the height threshold, or if the height of the object entering the passage T is less than the height threshold and the temperature of the object entering the passage T is within the set temperature range, the control unit 5 identifies the object as a person (passerby). If the height of the object entering the passage T is less than the height threshold and the temperature of the object entering the passage T is outside the set temperature range, the control unit 5 identifies the object as luggage carried by a person (passerby).

Returning to Figure 3, in step S13, the control unit 5 links 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 entering the passage T (i.e., the object moving within the passage T) is a person (pedestrian) or luggage.

In step S14, the control unit 5 determines whether another object entered the passage T following the aforementioned object. If another object entered the passage T (step S14: YES), the control unit 5 proceeds to step S15. On the other hand, if no other object entered the passage T (step S14: NO), the control unit 5 proceeds to step S17 (Figure 4).

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 entering the passage T is a person or luggage (see Figure 7).

In step S16, the control unit 5 associates the identification result from step S15 with another object that 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.

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 the object recognized as a person (hereinafter simply referred to as "person") has reached the center of the passage T. If the person reaches the center of the passage T, the control unit 5 proceeds to the process in step S18.

In step S18, the control unit 5 determines whether the number of passage rights is 1 or greater. 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 have entered passage T without holding up a passage ticket medium with the correct passage ticket information recorded on the information reading unit 31, i.e., 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).

On the other hand, if the number of passage rights is one 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 one or more (step S18: YES), the control unit 5 proceeds directly to the processing in step S19.

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, instead of determining whether the person passed through gate 32, the control unit 5 may determine whether the person exited passage T.

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".

In step S21, the control unit 5 determines whether or not there is an object following the person who 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.

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 closing operation of gate 32 must be performed 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. If the following object (luggage) has passed through gate 32, the control unit 5 proceeds to step S24 to close gate 32.

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 reached 0). Therefore, if the following object is not cargo (step S22: NO), the control unit 5 proceeds to step S24 and quickly closes gate 32 in order to prevent the passage of the following object (person), that is, to prevent a person who is not permitted to pass through passage T from passing through passage T in a tailgating manner.

As described above, the gate device 1 according to this embodiment includes a device body 3 positioned 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 includes 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, temperature sensor 34, and height sensor 35.

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 pedestrians 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 is a person (pedestrian) or luggage based on the detection signals from the temperature sensor 34 and height sensor 35 (see steps S12, S15 in Figure 3 and Figure 6). The control unit 5 then reflects the identification result—whether the object is a person (pedestrian) or luggage—in the operation of the gate 32 (especially the closing operation). That is, 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).

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-facing side of the device body 3. Therefore, 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 previously 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; complex processing is not required. Therefore, the complexity of the system configuration can also be suppressed.

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.

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 configuration. 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.

Furthermore, in the above-described embodiment, the control unit 5 identifies an object (entering 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.

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.
