Description

  The present invention is used, for example, in a bicycle parking lot for a bicycle and a motorcycle (herein, `` motorcycle '' means a so-called `` motorcycle '' and includes not only a motorcycle in a narrow sense but also a motorbike). The present invention relates to a device for discriminating between a bicycle and a motorcycle.

  In general, when management is performed at a bicycle / motorcycle bicycle parking lot, collection is made with a difference in charge according to the required parking space. In order to perform unmanned management in such a bicycle / motorcycle parking lot, it is necessary to install a discrimination device between the bicycle and the motorcycle at the entrance / exit (exit or entrance) of the bicycle parking lot. As this type of discriminating device, for example, a groove type discriminating device as described in Patent Document 1 is known.

This groove type discriminating device is provided with a groove having a width wider than the tire width of the bicycle and smaller than the tire width of the motorcycle in the traveling passage of the entrance / exit in the bicycle parking lot, and detects whether the tire can enter the groove. Thus, the type of motorcycle (bicycle or motorcycle) is to be determined.
JP-A-8-296336

  However, in the above groove type, the width of the groove is slightly wider than the tire width of the bicycle and is set very narrow. Care must be taken as thread passes through the hole, and it is not easy for the first time user to perform such a delicate operation with certainty, resulting in confusion for the user. . Further, in the case of a motorcycle, since the tire is wide and cannot pass through the groove, a force work is required to ascend and descend a slope provided separately from the groove. As a result, the efficiency of traffic when entering and leaving the bicycle parking area was significantly reduced, causing traffic jams at the entrance and exit.

  The present invention has been made in view of the above-described conventional problems, and the problem to be solved is to pass through the entrance / exit of a bicycle parking lot in order to realize unmanned management of a bicycle / motorcycle bicycle parking lot. It is an object of the present invention to provide a two-wheeled vehicle discriminating apparatus and method that enable smooth passage while accurately discriminating the type of motorcycle (bicycle or motorcycle).

In order to solve the above problems, the present invention adopts the following configuration.
First, the motorcycle discriminating device of the present invention is an apparatus for discriminating whether a two-wheeled vehicle passing through a predetermined passage at an entrance of a bicycle / motorcycle bicycle parking lot is a bicycle or a motorcycle. Whether the thickness (the “tire portion thickness” referred to here is the total thickness of the tire and the rim including the thickness of the rim that supports the inner peripheral portion of the tire) is greater than a predetermined value. And a discrimination means for discriminating whether the two-wheeled vehicle passing through the passage is a bicycle or a motorcycle based on a detection result by the thickness detection means.

  According to the apparatus of the present invention having such a configuration, when the two-wheeled vehicle passes through the predetermined passage, the thickness of the tire portion is detected by the thickness detecting means, and the type of the two-wheeled vehicle is determined based on the detection result. Made. That is, focusing on the fact that the thickness of the tire portion is different between the bicycle and the motorcycle (the latter is thicker than the former), and depending on whether the thickness is larger than a predetermined value, the motorcycle The type of can be clearly identified. Therefore, when entering and exiting a bicycle parking lot, etc., simply passing the motorcycle along a sufficiently wide passage allows the type of the motorcycle to be automatically and accurately identified without any awareness of the user. It will be. As a result, compared to the above-described conventional technology, the user is not forced to perform delicate work such as passing a bicycle tire through a narrow groove, and the ability to pull up and down a slope by pulling a heavy motorcycle. Work becomes unnecessary.

  Here, various configurations can be adopted for the thickness detection means and the discrimination means within a range in which the type of the motorcycle can be discriminated based on the thickness of the tire portion, and a desirable example is shown below.

  As an example of the thickness detecting means, a first photoelectric sensor composed of a first light projector and a first light receiver that face each other across the passage and is disposed at a first height with respect to the road surface of the passage. A second light projector and a second light emitter facing each other across the passage, located immediately below or near the first photoelectric sensor, and disposed at a second height with respect to the road surface of the passage. The first photoelectric sensor is set at a position higher than the thickness of the tire portion of the bicycle and lower than the thickness of the tire portion of the motorcycle, One in which the second height is set at a position lower than the thickness of the tire portion of the bicycle is conceivable.

  In that case, as the discriminating means, when the first photoelectric sensor is in a light-transmitting state while the second photoelectric sensor is in a light shielding state, it is determined that the two-wheeled vehicle passing through the passage is a bicycle, On the other hand, when the first photoelectric sensor remains in the light-shielded state while the second photoelectric sensor is in the light-shielded state, it is desirable to determine that the motorcycle passing through the passage is a motorcycle. .

  Such discrimination processing is performed for the following reason. That is, in the middle of the passage of the motorcycle, the first photoelectric sensor is set to the first height (that is, a position higher than the thickness of the tire portion of the bicycle and lower than the thickness of the tire portion of the motorcycle) as described above. When the second photoelectric sensor is installed at a second height (that is, a position lower than the thickness of the bicycle tire portion), when the motorcycle passes through the second photoelectric sensor, the thickness of the tire portion is set. Accordingly, since the states of the first and second photoelectric sensors transition, it becomes possible to accurately determine the type of the motorcycle based on the difference in the transition pattern.

  More specifically, first, the second photoelectric sensor installed at the second height is always temporarily blocked by the tire portion passing there regardless of the type of motorcycle (the light from the projector is blocked). By detecting this state, it is determined that the two-wheeled vehicle is about to pass therethrough. In this state, if the two-wheeled vehicle tries to pass as it is, the first photoelectric sensor is a bicycle if the two-wheeled vehicle is a bicycle from the relationship between the thickness of the tire portion and the installation height (first height) of the first photoelectric sensor. The sensor temporarily enters a light-transmitting state (a state in which light from the projector is incident on the light receiver without being blocked). On the other hand, in the case of a motorcycle, the first photoelectric sensor remains in a light-blocking state. Therefore, it is possible to accurately determine the type of the two-wheeled vehicle passing through the passage only by confirming the state of the first photoelectric sensor during the period in which the second photoelectric sensor is in the light shielding state.

  As another desirable example of the thickness detecting means, a plurality of sets of the first and second photoelectric sensors are provided, and each set is located at different positions along the traveling direction of the passage (that is, to some extent with respect to each other). It is also possible to arrange them at intervals.

  In that case, as the discriminating means, in at least one of the plurality of sets of the first and second photoelectric sensors, the first photoelectric sensor is in a light-transmitting state while the second photoelectric sensor is in a light shielding state. When the two-wheeled vehicle passing through the passage is a bicycle, on the other hand, while the second photoelectric sensor is in a light-shielding state in all of the plurality of sets of the first and second photoelectric sensors. In addition, when the first photoelectric sensor is also in the light-shielded state, it is desirable to determine that the motorcycle passing through the passage is a motorcycle.

  In this case, if a bicycle nozzle passing through the passage from the tire portion of the bicycle toward the center of the wheel becomes an obstacle, it is supposed to be in a translucent state. Even in the case where one photoelectric sensor is in a light-shielded state, the above-described air-filling nozzle or the like is used for the other first photoelectric sensor arranged with a positional shift with respect to the traveling direction of the passage. Does not become an obstacle and can be accurately detected. Therefore, by comprehensively judging the state of the first and second photoelectric sensors provided in a plurality of sets, an erroneous determination due to an obstacle is made as compared with the case where only one set of the first and second photoelectric sensors is arranged. By avoiding as much as possible, more accurate discrimination becomes possible.

  The second photoelectric sensor is not necessarily a photoelectric sensor because it is only intended to detect the presence or absence of the passage of the motorcycle. For example, the second photoelectric sensor is a pressure switch arranged on the road surface of the passage. May be.

  Next, the motorcycle discriminating method of the present invention is a method for discriminating whether a two-wheeled vehicle passing through a predetermined passage at a doorway of a bicycle / motorcycle parking lot is a bicycle or a motorcycle. A first sensor (corresponding to the second photoelectric sensor and pressure switch described above) that detects and turns on the tire portion regardless of the type of motorcycle passing therethrough is disposed, and the first sensor is arranged with respect to the traveling direction of the passage. The presence or absence of an object passing through the predetermined height is detected at a predetermined height that is higher than the thickness of the bicycle tire and lower than the thickness of the motorcycle tire. A second sensor (corresponding to the first photoelectric sensor described above) is disposed, and when the second sensor detects the absence of an object when the first sensor is in the ON state, If the passing two-wheeled vehicle is determined to be a bicycle, and the second sensor is still detecting the presence of an object when the first sensor is on, the two-wheeled vehicle passing through the passage is automatically It is characterized by discriminating that it is a two-wheeled vehicle.

  According to the method of the present invention having such a configuration, the two-wheeled vehicle can be simply passed through the passage by the same principle as in the case of the above-described device of the present invention. The type can be automatically and accurately determined.

  According to the present invention, a user of a bicycle parking lot or the like is not forced to perform a delicate work such as passing a bicycle tire through a narrow groove, and a force work such as pulling a heavy motorcycle up and down a slope is also possible. Since it becomes unnecessary, the efficiency of traffic when entering and leaving a bicycle parking lot can be remarkably improved, and the occurrence of traffic jams at the entrance and exit can be suppressed as much as possible.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(First embodiment)
FIG. 1 is a plan view when a two-wheeled vehicle discriminating device according to a first embodiment of the present invention is installed at a bicycle parking lot entrance / exit.

  The configuration of the bicycle parking lot entrance shown in FIG. 1 is only an example, and has a general configuration corresponding to unmanned management, that is, a motorcycle from outside to inside (or from inside to outside) of the bicycle parking lot. A passage S is provided so that 6 can pass through, and a settlement machine (or a ticket issuing machine) 1 is installed on one side across the passage S, and a gate A7 and a gate B8 are installed on the other side. Here, the payment machine (or ticket issuing machine) 1 is a device for collecting parking fees for bicycles and motorcycles and for issuing parking tickets. Further, the two gates A7 and B8 are for arranging the passage of the two-wheeled vehicle 6 in order, and are arranged at an interval of less than one two-wheeled vehicle along the traveling direction of the passage S, and are 90 degrees from each other. The two-wheeled vehicle 6 is configured such that the two-wheeled vehicle 6 is allowed to travel when the other is in a position where the two-wheeled vehicle 6 is not allowed to travel. It is possible to guide one by one in turn.

The two-wheeled vehicle discrimination device installed in such a bicycle parking lot entrance / exit has the following configuration.
That is, it has two upper and lower photoelectric sensors as thickness detecting means for detecting whether or not the thickness of the tire portion of the two-wheeled vehicle 6 passing through the passage S is larger than a predetermined value. The light projector side is referred to as photoelectric sensor light projector 2- (a), and the light receiver side is referred to as photoelectric sensor light receiver 3- (a). The photoelectric sensor projector 2- (a) and the photoelectric sensor receiver 3- (a) are provided with a protective cover for blocking external dirt, and are referred to as a photoelectric sensor cover 4. The photoelectric sensor projector 2- (a) is irradiated with a projection beam 5- (a). In order to receive the projection beam, the photoelectric sensor receives light so as to come to the facing position across the traveling path of the motorcycle 6. Device 3- (a) is installed.

  FIG. 2 is a diagram illustrating detailed positions of the photoelectric sensor projector 2- (a) and the photoelectric sensor receiver 3- (a). The photoelectric sensor projector 2- (a) is composed of two stages. The upper stage is referred to as a discriminating projector 2-1 and the lower stage is referred to as a discriminating command projector 2-2. The discrimination command projector 2-2 is located below the discriminating projector 2-1. It is installed at the position (below or near it). Similarly, the photoelectric sensor light receiver 3- (a) is also composed of two stages. The upper stage is referred to as a discrimination light receiver 3-1, the lower stage is referred to as a discrimination command light receiver 3-2, and the discrimination command light receiver 3-2 is discriminated. It is installed at a position below (below or in the vicinity of) the light receiver 3-1. Note that “below or in the vicinity thereof” means that the position may be slightly deviated from the position immediately below within a range in which detection and determination processing described later can be performed.

  In FIG. 2, the installation height H1 of the discriminating projector 2-1 and the discriminating light receiver 3-1 will be described in detail later, but discriminates whether the type of the motorcycle is a bicycle or a motorcycle based on the thickness of the tire portion. In other words, it is set at a position higher than the thickness of the tire portion of the bicycle and lower than the thickness of the tire portion of the motorcycle. The height H1 is set to an optimum value with reference to tire thicknesses of various types of vehicles in order to ensure the accuracy of discrimination. For example, 60 to 70 mm is appropriate. It is not limited.

  In FIG. 2, a discrimination command projector 2-2 and a discrimination command light receiver 3-2 are used to detect whether or not a motorcycle has passed and issue a discrimination command, as will be described in detail later. The height H2 is set at a position sufficiently lower than the thickness of the tire portion of the bicycle.

  In addition to the photoelectric sensor as the thickness detection unit described above, the two-wheel vehicle determination device according to the present embodiment includes a determination unit that determines the type of the motorcycle based on the detection result. This discrimination means is realized by the control unit shown in FIG.

  Next, the discrimination process executed by the control unit will be described with reference to FIGS. FIG. 3 shows the state transition when the bicycle passes through the passage S, and FIG. 4 shows the state transition when the motorcycle passes through the passage S.

  First, the case of a bicycle will be described with reference to FIG. Since the wheel to be discriminated is a circular annular body having a certain thickness, when it reaches the detection area of the photoelectric sensor while rotating, as shown in FIG. The projection beam of the discrimination projector 2-1 at (height H1) is shielded by the tire 9. Further, when the center of the wheel exceeds the point A which is the position shown in FIG. 3A, this time, the projection beam of the discrimination command projector 2-2 at the lower position (height H2) is the tire 9 or The rim 10 starts to be shielded from light, and the discrimination command projector 2-2 continues to be shielded until immediately before the center of the wheel reaches the point B as shown in FIG.

  As described above, while the projection beam of the discrimination command projector 2-2 is blocked, it is recognized that the discrimination command is continuously output. Here, since H1 is set at a position higher than the thickness of the tire portion (tire 9 and rim 10) of the bicycle and lower than the thickness of the tire portion of the motorcycle as described above, as shown in FIG. When the bicycle passes, any point in time during which the projection beam of the discrimination command projector 2-2 is shielded by the tire portion (that is, the discrimination command is continuously output), for example, As shown in FIG. 3B, before and at the moment when the center of the wheel reaches the position of the discriminating projector 2-1, the projected beam of the discriminating projector 2-1 reaches the discriminating receiver 3-1. Then, the light blocking state is switched to the light transmitting state. Therefore, when the discrimination light receiver 3-1 receives the projection beam of the discrimination projector 2-1 in a state where the discrimination command is output, it is determined that the type of the two-wheeled vehicle is a bicycle.

That is, the steps for detecting and discriminating a bicycle are as follows.
First, the projection beam of the discriminating projector 2-1 is shielded (FIG. 3A).
Second, it recognizes that the projection beam of the discrimination command projector 2-2 is blocked (FIG. 3B), and outputs a discrimination command.

Thirdly, during the output of the discrimination command, the light projection beam of the discrimination projector 2-1 is received by the discrimination light receiver 3-1 (FIG. 3B).
Fourth, the light projection beam of the discriminating light projector 2-1 is shielded (FIG. 3C).

Fifth, the projection beam of the discrimination command projector 2-2 is received by the discrimination command light receiver 3-2 (FIG. 3C).
Sixth, the projection beam of the discriminating projector 2-1 is received by the discriminating photodetector 3-1 (FIG. 3 (d)).

  Here, in the third step (FIG. 3B), a discrimination command is issued from the discrimination command projector 2-2, and the projection beam of the discrimination projector 2-1 is the discrimination light receiver 3-1. The two-wheeled vehicle is determined to be a bicycle.

On the other hand, in the case of the motorcycle shown in FIG. 4, since the thickness of the tire portion is larger than H1, the detection / discrimination process is as follows.
First, the projection beam of the discriminating projector 2-1 is shielded (FIG. 4A).

Second, it recognizes that the projection beam of the discrimination command projector 2-2 is blocked (FIG. 4B), and outputs a discrimination command.
Third, the projection beam of the discrimination command projector 2-2 is received by the discrimination command light receiver 3-2 (FIG. 4C).

Fourth, the light projection beam of the discriminating projector 2-1 is received by the discriminating light receiver 3-1 (FIG. 4 (d)).
Here, during the second step (FIG. 4B) to the third step (FIG. 4C), the discrimination command projector 2-2 has issued a discrimination command, and the discrimination projector 2- Since the 1 projection beam remains shielded, the motorcycle is determined to be a motorcycle.

The discrimination result obtained in this way is reflected in the settlement of the parking fee, the issuance of the parking ticket, etc. in the settlement machine (or ticket issuing machine) 1 shown in FIG.
As described above, according to the two-wheeled vehicle discrimination device according to the present embodiment, when the two-wheeled vehicle enters and leaves the bicycle parking lot, the user simply passes the two-wheeled vehicle along the sufficiently wide passage S so that the user can Even without being conscious, the type of motorcycle is automatically and accurately determined. In particular, the discriminating projector 2-1 and discriminating photoreceiver 3-1, the discriminating command projector 2-2 and the discriminating command receiver 3-2 are respectively installed at the same heights H1 and H2 with respect to the traveling path surface. Since the projection beam from each projector is parallel to the traveling path surface, the height of the projected beam with respect to the road surface is constant regardless of the position in the width direction of the traveling path. Accurate discrimination results can be obtained no matter where you pass.

Therefore, while making it possible to accurately discriminate in this way, the delicate work of passing a bicycle tire through a narrow groove like a conventional groove type discriminating device, or pulling a heavy motorcycle to ascend the slope. As a result, it is not necessary to perform a power work such as getting off, and as a result, it is possible to remarkably improve the efficiency of traffic when entering and leaving the bicycle parking lot, and it is possible to minimize the occurrence of traffic congestion at the entrance and exit.
(Second Embodiment)
FIG. 6 is a plan view when the two-wheeled vehicle discriminating apparatus according to the second embodiment of the present invention is installed at the parking lot entrance / exit. In addition, the structure of the bicycle parking lot entrance / exit is the same as that of the first embodiment shown in FIG. 1, and the same reference numerals are given to the same elements as those in FIG.

  In this embodiment, in order to prevent the erroneous determination predicted in the first embodiment as much as possible, a plurality of sets of determination projectors, determination receivers, determination command projectors and determination command receivers (here, three sets as an example) It is provided. In other words, in the first embodiment, for example, as shown in FIG. 5, the reflector 12 attached to the bicycle air nozzle 11 or the spokes of the wheel happens to be an obstacle, and the projector of the discriminating projector 2-1. There is a case where the light beam is interrupted. In this case, the light receiving beam of the discriminating projector 2-1 is not received by the discriminating light receiver 3-1, and the bicycle is erroneously determined as a motorcycle. Therefore, in order to reduce the possibility of erroneous determination, a plurality of sets of determination light projectors and determination light receivers, determination command light projectors and determination command light receivers are installed, and the respective sets are set at different positions along the traveling direction of the passage S. (Ie, a predetermined distance from each other).

In FIG. 6, each of the upper and lower two-stage photoelectric sensors constituting each set is composed of a projector and a light receiver as in the first embodiment, and the photoelectric sensor projector 2- (b) is connected to the projector side. The side is referred to as photoelectric sensor light receiver 3- (b). The photoelectric sensor projector 2- (b) is irradiated with a projection beam 5- (b). In order to receive the projection beam, the photoelectric sensor receives light so as to come to the facing position across the traveling path of the motorcycle 6. Device 3- (b) is installed.
FIG. 7 is a diagram illustrating detailed positions of the photoelectric sensor projector 2- (b) and the photoelectric sensor receiver 3- (b). The photoelectric sensor projector 2- (b) has three rows and two stages, and the upper projector side is referred to as a discriminator projector 2-1-1, discriminator projector 2-1, and discriminator projector 2-1-2. Are referred to as a discrimination command projector 2-2-1, a discrimination command projector 2-2, and a discrimination command projector 2-2-2. The discrimination command projector 2-2-1, the discrimination command projector 2-2, and the discrimination command projector 2-2-2 are positioned below the discrimination projector 2-1-1, the discrimination projector 2-1, and the discrimination projector 2-1-2. (Below or near it).
Similarly, the photoelectric sensor light receiver 3- (b) is configured in three rows and two stages, and the upper stage on the light receiver side is a discrimination light receiver 3-1-1, a discrimination light receiver 3-1, and a discrimination light receiver 3-1. -2 and the lower stage on the light receiver side are referred to as a discrimination command light receiver 3-2-1, a discrimination command light receiver 3-2, and a discrimination command light receiver 3-2-2. The discriminating command projector 3-2-1, the discriminating command projector 3-2, the discriminating command projector 3-2-2, the discriminating light receiver 3-1-1, the discriminating light receiver 3-1, and the discriminating light receiver 3-1- 2 below (at or directly below). Also in this case, “below or in the vicinity thereof” means that the position may be slightly deviated from the position immediately below within a range in which detection and determination processing described later can be performed.

  As described above, in the configuration including three sets of the upper and lower two-stage photoelectric sensors, the type of the motorcycle is determined as follows. That is, as the motorcycle passes through the passage S, the state of each of the three sets of photoelectric sensors transitions as shown in FIG. 3 or 4 as in the case of the first embodiment. The state of the three sets of photoelectric sensors is comprehensively determined. Specifically, in at least one of the three sets of photoelectric sensors, when the discrimination beam is received by the discrimination light receiver while the discrimination command is issued from the discrimination command projector, It is determined that On the other hand, if all of the three sets of photoelectric sensors are in the state in which a discrimination command is issued from the discrimination command projector, the projection beam of the discrimination projector remains unreceived by the discrimination light receiver, the motorcycle is a motorcycle. Is determined.

  By doing in this way, if the inflating nozzle 11 protruding from the tire portion of the bicycle is an obstacle as shown in FIG. 5, it seems that the projection beam from the projector 2-1 is blocked. Even in such a case, the inflating nozzle 11 does not become an obstacle for the projection beams from the other two projectors 2-1-1 and 2-1-2. In this state, it is possible to reliably receive the projection beam. Further, even if the reflector 12 becomes an obstacle for the projection beam from the projector 2-1-2, there is no obstacle for the light from the other projector 2-1-1. Since it does not exist, reliable detection is possible. As a result, compared with the case where only one set of photoelectric sensors is arranged, erroneous determination due to an obstacle can be avoided as much as possible, and more accurate determination can be performed.

In the second embodiment, three sets of upper and lower two-stage photoelectric sensors are used, but the present invention is not limited to this, and two sets or four or more sets may be used.
(Third embodiment)
FIG. 8 is a diagram illustrating a main part of a two-wheeled vehicle discrimination device according to the third embodiment of the present invention.

  In this embodiment, a pressure switch 13 is installed in the road surface in place of the discrimination command projector 2-2 and the discrimination command light receiver 3-2 in the first embodiment. Here, in the first embodiment, the reason why the light projectors 2-2 and the light receivers 3-2 for determination commands are provided is to reliably detect the presence or absence of the passage of the two-wheeled vehicle regardless of the type thereof. When the center of the wheel of the two-wheeled vehicle is in the vicinity of the discriminating projector, the discriminating command is surely continuously issued. Therefore, as an alternative to the projector 2-2 and the light receiver 3-2, A pressure switch 13 (for example, a so-called tape switch) that is turned on by stepping on a tire anywhere between the discriminating projector and the discriminating light receiver is provided at a position (directly or in the vicinity thereof). In this case, it is desirable that the pressure switch 13 is laid on the base plate 14 on the traveling path, and further, a buffer material 15 such as a rubber plate cover is placed on the pressure switch 13 for the purpose of protecting the pressure switch 13.

  In such a configuration, as shown in FIG. 12, the control unit executes the discrimination process based on the states of the discriminating projector 2-1, the discriminating light receiver 2-2, and the pressure switch 13. That is, in the control unit, as shown in FIG. 8, while the pressure switch 13 is stepped on by the two-wheeled vehicle and is in the on state (that is, while the determination command is issued), the light projection beam from the determination light projector 2-1 Is received by the discriminating light receiver 3-1, it is discriminated that it is a bicycle. On the other hand, while the pressure switch 13 is in the ON state, the light projection beam from the discriminating projector 2-1 is discriminated from the discriminating light receiver 3-. If no light is received at 1, it is determined that the vehicle is a motorcycle.

Even with such a configuration, the same effect as in the first embodiment can be expected.
As shown in FIGS. 9 and 10, a plurality of pressure switches 13 are installed in the traveling direction of the passage S, and a determination light projector and a determination light receiver are installed at positions corresponding to the pressure switches, respectively. It is also possible to obtain the same operation and effect as in the second embodiment. Here, FIG. 9 is a plan view showing a plurality of (in this example, four) pressure switches installed on the road surface, and FIG. 10 is a cross-sectional view taken along the line AA.

  In this case as well, in substantially the same manner as in the second embodiment, a determination command is issued from the pressure switch in at least one of the four sets by comprehensively determining the states of the four pressure switches and the photoelectric sensor. When the light beam of the discriminating projector is received by the discriminating light receiver in the state where the discriminating light is received, the discriminating projector is discriminated as a bicycle. If the projected beam is not received by the discrimination light receiver, it is discriminated that it is a motorcycle.

  By doing in this way, as in the second embodiment, compared with the case where only one set of pressure switch and photoelectric sensor is arranged, it is possible to avoid erroneous determination due to obstacles as much as possible and perform more accurate determination. .

  In the embodiment described above, the photoelectric sensor and the pressure switch are used as means for detecting the presence / absence of the tire portion, but may be configured using other sensors and switches.

Further, the object for installing the present invention is not necessarily limited to the entrance / exit of the bicycle / motorcycle parking lot, and may be installed in other places as necessary.
Furthermore, the discrimination means in the present invention is not necessarily installed near the thickness detection means. For example, the discrimination means is installed at a location far away from the thickness detection means, and the discrimination means and the thickness detection means are wired or wireless. It is also possible to remotely manage the types of motorcycles entering and exiting the bicycle parking lot by connecting with a communication line or network.
