DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a management apparatus capable of unmannedly managing a bicycle parking lot including a motorcycle such as a motorbike.

[0002]

2. Description of the Related Art Conventionally, as the use of bicycles, motorcycles and the like has increased, the number of "parked bicycles" and "parked bicycles" has become a social problem. Local governments,
Railway companies and individuals are constructing “parking lots for bicycles” (hereinafter referred to as “bicycle parking lots”). In order to use bicycle parking lots effectively, it is necessary to manage them appropriately.
A “manager” is often assigned to manage bicycle parking facilities and users. In most cases, the manager is an "elderly person" whose age group is high. If an elderly person is a manager, it is difficult to work early in the morning or late at night, so the parking lot is unmanned. In such an unmanned time zone, the management of the bicycle parking lot is practically impossible, and the bicycle parking lot is closed and cannot be used.

FIG. 10 shows a configuration of an unmanned "automobile" parking lot. An entrance 2 is provided in the parking lot 1,
The entrance vehicle 3 enters from the outside. The entrance vehicle 3 stops at the parking ticket issuing machine 4 and receives the parking ticket. As a result, the entrance gate 5 opens, and the entrance vehicle 3 can enter the parking lot 1. At the exit 6 of the parking lot 1, the participating vehicles 7 stop at the automatic toll settlement machine 8, and when the toll has been settled, the exit gate 9 opens to allow entry to the outside.

[0004] In the parking lot 1, a parking area 10 is provided between the entrance 2 and the exit 6, and parking can be continued until the entering vehicle 3 enters. Generally, from the time when the parking ticket issuance machine 4 issues a parking ticket to the time when the fee is automatically settled by the automatic fee adjustment machine 8, the entry vehicle 7 sends the charge to the automatic price adjustment machine 8 in accordance with the time. Payment is made. For this reason,
Loop coils 11, 12, 13, and 14 are buried in the passage, and a parking ticket issuing machine 4, an entrance gate 5, an automatic fare adjusting machine 8
And whether or not the entrance vehicle 3 and the exit vehicle 7 are present at the exit gate 9. The detection of the vehicle includes an oscillation circuit 15 connected to each of the loop coils 11, 12, 13, and 14,
The change is detected as a change in the oscillation frequency of 16, 17, or 18.

In a rush hour, etc., the entrance vehicles 3 are often congested at the entrance 2, whereas the exit vehicles 7 at the exit 6 vary in entry time, and are relatively less congested. For this reason, the automatic payment machine 8 is often provided at the exit 6.

[0006] In a bicycle parking lot such as a bicycle or a motorcycle, if the same unmanned system as the parking lot is provided, it is possible to manage the bicycle parking lot even in the unmanned time zone. In order to carry out management in such a time zone, some physical method such as an entrance gate is installed at the entrance of the bicycle parking lot premises, a bicycle parking fee is collected with a commuter pass or coin, etc. It is necessary to prevent the burden from being differentiated from other users.

[0007]

In an unmanned parking system for an automobile as shown in FIG.
And the participating vehicle 7 with the loop coils 11, 12, 13, 1
4, and is electromagnetically detected. However, for a bicycle, a motorcycle, or the like, the loop coils 11, 12, 13, and 14 buried in such a passage cannot sufficiently detect the situation. This is because, in the case of an automobile, an iron plate having a somewhat large area can be regarded as passing over the loop coil, whereas a bicycle or the like cannot obtain a sufficient projection area.

A method of optically detecting passage of a bicycle or the like has been considered. For example, there is a prior art in which, when a user or a bicycle is sensed by a photoelectric sensor or the like, an entrance gate is opened to enable entry into a bicycle parking lot. The basic principle of a photoelectric sensor is to detect the presence or absence of an object based on the amount of light received. Therefore, not only people and bicycles, but also other objects are packed, especially intentional papers,
Packing of gum or leaves, temporary placement of objects,
For example, there is a response with a bag, an umbrella, and the like. In addition, they are easily soiled by dust, rainwater, muddy water, and the like, and are likely to cause false reactions due to the soiling. In order to prevent this, periodic inspection and maintenance are required. Further, with a photoelectric sensor, it is impossible to discriminate a person from a bicycle or the like, and it is not possible to accurately manage the number of bicycles or the like parked in a bicycle parking lot.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a bicycle parking lot management apparatus capable of accurately detecting the entry of a bicycle or a motorcycle into a bicycle parking lot or the departure of a bicycle or a motorcycle from the bicycle parking lot, and reliably managing the bicycle parking lot. That is.

[0010]

SUMMARY OF THE INVENTION The present invention relates to a bicycle parking lot management apparatus for managing the entry and exit of bicycles and motorcycles to and from a bicycle parking lot, which is provided along at least one of an entrance passage and an exit passage. A handrail that is partitioned to have a width equivalent to one bicycle or a single vehicle, and a gate that is provided at an intermediate portion of the passage and that can switch between a state in which traffic along the handrail is blocked and a state in which traffic is allowed, A coil that generates a line of magnetic force in a direction intersecting a plane including a passing wheel in the passage, detecting means for detecting passage of a bicycle or a single vehicle from a change in inductance of the coil, and a detection result from the detecting means. And a control means for switching gates so that the number of bicycles or motorcycles entering and exiting the bicycle parking lot through the passage is limited to one by one. It is a field management device. According to the present invention, a magnetic field line is generated from a coil disposed at at least one of the entrance and the exit of a bicycle parking lot in a direction intersecting a plane including wheels of a bicycle or the like passing through a passage. When a bicycle or the like passes along a handrail partitioning a passage, an eddy current flows through a conductor of a wheel or a frame of the bicycle or the like, so that the inductance of the coil changes. Since the detecting means detects the passage of a bicycle or the like from the change in the inductance of the coil, the managing means switches the gate to reliably limit the passage of a bicycle or a single vehicle at a time and to accurately manage the bicycle parking lot. Can be.

In the present invention, the handrail, the gate,
The coil and the detection means are provided in an entrance passage and an exit passage of the bicycle parking lot, respectively, the management means manages the number of bicycles or motorcycles in the bicycle parking lot based on a detection result from each detection means, The present invention is characterized in that the status display of full or empty in the hall is performed according to the number of vehicles.
According to the present invention, in the entrance passage and the exit passage of the bicycle parking lot,
Since the coil and the detection means are provided, it is possible to accurately detect a bicycle or the like entering and exiting a bicycle parking lot. Since the management means can accurately grasp the number of bicycles or motorcycles entering or exiting the bicycle parking lot, it should also accurately manage the number of bicycles or motorcycles in the bicycle parking lot and display the status of full or empty vehicles in the parking lot. Can be.

Further, the present invention is characterized in that a pair of coils having a diameter equivalent to a wheel diameter of a bicycle or a motorcycle are arranged so as to face each other and connected in series. According to the present invention, when a bicycle or the like passes through an entrance or an exit, it passes between a pair of coils arranged to face each other. Since the diameter of each coil is substantially the same as the wheel diameter of a bicycle or a motorcycle, the passage of wheels of a bicycle or the like can be detected efficiently.

1, 32; 33, 34 are stored respectively. Each of the loop coils 31, 32; 33, 34 is disposed so as to face each other across the passage. Near the ends of the entrance gate 25 and the entrance 22, passage detection lines 35 and 36 for detecting the presence of an object by infrared rays are provided, respectively. Also at the exit section 26, near the exit gate 29 and the end of the passage, the passage detection line 3 by infrared rays is used.
7, 38 are provided respectively. A metal detection coil 39 is buried in the vicinity of the start end of the passage of the entrance section 22 so that a metal passing therethrough can be detected. Exit 26
A vehicle type discriminating device 40 is installed near the beginning of the aisle.
The type of a passing bicycle, a motorbike, a motorcycle, etc. is determined.

FIG. 3 shows a schematic electrical configuration of the management device shown in FIGS. The detection means 42 and the output of the passage detection lines 35 and 36 and the output from the metal detection coil 39 are input from the entrance 22 to the management means 41 realized by a computer or the like, and the detection means 43 and the passage detection Outputs from the lines 37 and 38 and the vehicle type discriminating device 40 are input, respectively. The detecting means 42 and 43 include loop coils 31 and 32;
Are respectively connected. From the management means 41, the entrance 2
Outputs to the second entrance gate 25, the exit gate 29 of the exit section 26, and the full / vacant indicator 44 are derived. Further, the charge settlement device 30 issues a command such as display of charge and data reception such as receipt of charge.

FIG. 4 shows the operation of the management device 21 at the entrance 22. The operation is started from step a1.
In step 2, the control waits until a bicycle or the like is detected based on a signal from the detection means 42. Step a when a bicycle or the like is detected
It moves to 3 and determines whether or not a bicycle or the like can be newly stored in the bicycle parking lot. When it is possible, the entrance gate 25 is opened in step a4, the output from the passage detection line 35 is monitored in step a5, and the passage of the gate is awaited. In step a6, the entrance gate 25 is closed. In step a7, the output from the passage detection line 36 is monitored, and the flow waits for a bicycle or the like to pass through the entrance 22. After passing through the entrance 22, the process returns to step a1 and waits for the next bicycle or the like to enter. If it is determined in step a3 that a bicycle or the like cannot be stored, the full / vacant indicator 44 indicates fullness in step a8. Step a1 when the full display is completed
Return to

FIG. 5 shows the operation of the exit unit 26 by the management device 21. The operation starts from step b1, and in step b2, the detection unit 43 waits for the bicycle or the like to reach the exit 26. In step b3, the system waits for the user of the bicycle or the like to settle the charge with the charge settlement device 30. When the settlement is completed, the exit gate 29 is opened in step b4,
In step b5, the system waits for passage through the gate while monitoring the output of the passage detection line 37. In step b6, exit gate 2
9 is closed, and the passage detection line 38 is monitored in step b7 to wait for the bicycle or the like to go out of the exit portion 29 to the outside. When the bicycle or the like goes out of the bicycle parking space 20, the process returns to step b2.

FIG. 6 shows the operation of the management device 21 for managing the number of bicycles parked in the bicycle parking lot 20. The operation is started from step c1, and in step c2, it is determined whether or not there is a vehicle such as a bicycle based on the output from the detecting means 42. When it is determined that the vehicle has entered, the number of bicycles parked in the bicycle parking lot is increased by 1 in step c3. When it is determined in step c2 that there is no entry, or when the process of increasing the number of vehicles in step c3 ends, the process proceeds to step c4. Step c
4, the output from the detection unit 43 causes the outlet 29
It is determined whether or not there is a departure of a bicycle or the like that goes out from the outside. When it is determined that there is a departure, the process proceeds to step c5, and the number of bicycles parked in the bicycle parking lot is reduced by one. When it is determined that there is no departure in step c4, or in step c
When step 5 is completed, it is determined in step c6 whether the number of bicycles or the like in the bicycle parking lot has reached a preset maximum value. When it is determined that the maximum value has been reached, the fullness display using the full / empty indicator 44 is performed in step c7. When it is determined in step c6 that the number of bicycles or the like in the bicycle parking lot has not reached the maximum value, or when the full display in step c7 ends, the process returns to step c2. 4, 5, and 6 are repeatedly performed by the management unit 41 of the management device 21 as long as power is supplied. The storage of the number of parked bicycles is performed by a memory in the management means 41.

FIG. 7 shows the principle of detecting a bicycle or a single vehicle by the loop coils 31 to 34. First, FIG.
The coil 5 that determines the resonance frequency of the oscillation circuit 50 as shown in FIG.
Assume that 1 is buried on the road surface. Oscillation circuit 5
A current 52 flowing from 0 to the windings of the coil 51 generates magnetic lines of force 53 around each winding according to the right-hand rule. In this state, as shown in FIG. 7B, when the metal plate 54 is brought close to the coil 51, the lines of magnetic force 53 are generated.
And an eddy current 55 is generated. The eddy current 55 generates a magnetic field 56 that weakens the magnetic field lines 53, so that the inductance of the coil 51 decreases and the oscillation frequency increases. Such an electromagnetic detection principle is widely used for detection by the loop coils 11, 12, 13, and 14 of the automobile shown in FIG. Oscillator circuits 15, 16, 17,
The oscillation frequency of 18 changes as the vehicle passes.
Note that the oscillation frequency is about 200 kHz.

Detecting the passage of a bicycle or the like electromagnetically means that the amount of the "conductor" of a bicycle or the like is smaller than the amount of the "conductor" of the vehicle and the floor of the vehicle has a road surface. In general, bicycles and the like are located at positions where wheels and frames are relatively far from the road surface. For this reason, the loop coils 11, 1 embedded in the road surface
Simply passing a bicycle or the like over 2, 13, 14 or the like cannot obtain a sufficient change in the oscillation frequency, and it is difficult to accurately detect the oscillation frequency. Guidelines for efficient detection of bicycles, etc. include improvements to increase the oscillation frequency variation by devising the shape, quantity, and arrangement of coils, measurement of frequency variation, and measurement by differential processing of variation. Detection may be performed.

FIG. 8 shows the relationship between the coil 51 and the passing position on the assumption that the bicycle 57 is detected.
FIG. 8A shows a state in which a rectangular coil 51 is buried in a road surface and one side thereof is parallel to a traveling direction 58 of a bicycle 57 or the like. That is, the angle α is set to 90 °. Assuming that the bicycle or the like 57 passes outside one side of the coil 51, as shown in FIG. 8A, the direction of the magnetic force line 53 by the current flowing through the coil 51 is orthogonal to the traveling direction 58, and A relatively large amount of eddy current 55 flows through metal plate 59 corresponding to. On the other hand, as shown in FIG. 8B, when the bicycle 57 passes through the inside of the coil 51,
Even when the angle β is 90 °, the amount of lines of magnetic force intersecting the metal plate 59 decreases, and the generated eddy current also decreases. Therefore, the change in the inductance of the coil 51 is reduced,
The amount by which the oscillation frequency of the oscillation circuit 50 rises also decreases. FIG.
As shown in (C), the traveling direction 58 of the bicycle or the like 57 is
In the case of intersecting with each side of the coil 51, the angle γ ≠ 9
It is 0 °, and even if a bicycle or the like 57 passes through the inside of the coil 51, the magnetic force lines 53 intersect with the equivalent metal plate 59, and an eddy current 55 is generated to some extent. Therefore, the oscillation circuit 50
Increases in the oscillation frequency of the IGBT.

FIG. 9 shows a process for deriving the configuration of the loop coils 31, 32, 33 and 34 incorporated in the management device 21 of FIGS. As shown in FIG.
If a pair of coils 61 and 62 are connected in series and a bicycle or the like is allowed to pass through the gap between them, the amount of change in the combined inductance of the coils 61 and 62 increases, and the oscillation circuit 50 The increase in the oscillation frequency of the device also increases. In a bicycle or a motorcycle, a metal plate equivalent to the front and rear wheels and the frame is considered to be divided into three parts. Therefore, a change in the oscillation frequency output in response to a bicycle or the like passing between the coils 61 and 62 also varies. You will have three peaks. It is preferable that the diameters of the coils 61 and 62 are substantially the same as the wheels of a bicycle or a motorcycle. The coils 61 and 62 erected from the road surface 60 are preferably housed in the handrails 23 and 24; 27 and 28 in FIGS.

FIG. 9B shows a state in which one coil 63 is erected and the other coil 64 is buried in the road surface 60, facing each other at an angle of 90 °. The magnetic lines of force synthesized by the coils 63 and 64 are equivalent to the magnetic lines of force generated from the coils inclined to have an angle of about 45 ° with respect to the road surface 60. Although the detection sensitivity is slightly lower than in the case of FIG. 9A, it is possible to almost certainly detect the passage of a bicycle or a single vehicle. FIG. 9 (C) shows an oval coil 65 on the road surface 60 such that the long axis intersects the traveling direction 58 of the bicycle 57 at about 45 °.
An example of installation almost completely to the width of the passage is shown. Also in this case, since the magnetic lines of force generated from the coil 65 with respect to the bicycle have a direction of 45 °, it is possible to always detect the bicycle 57 shown in FIG. 8 regardless of the position of the passage width.

When the passage of a bicycle or a single vehicle is detected by a change in the oscillation frequency, one bicycle or the like is not necessarily one.
Not only one frequency change, but a plurality of frequency changes occur. Therefore, it is erroneous to determine that one bicycle or the like passes through each frequency change. As in the embodiment of FIGS. 1 and 2, the entrance gate 25 and the exit gate 29
, And limit the number of passing bicycles to one by one,
Moreover, at the time of detection, it is necessary to perform a process of regarding a change in the oscillation frequency that continuously occurs within a certain time range as one unit.

[0025]

As described above, according to the present invention, the passage of a bicycle or a motorcycle can be reliably detected from the change in the inductance of the coil. Can be done unattended. If a gate device or the like is provided at the entrance, users who do not accompany a bicycle or the like can be excluded, and mischief can be prevented.

Further, according to the present invention, the number of departures at the entrance of the bicycle parking lot can be accurately grasped, so that the number of parked bicycles can be managed, and appropriate guidance can be provided to the user by displaying whether the vehicle is full or empty. Can also be performed.

Further, according to the present invention, a bicycle or a motorcycle passing between a pair of coils can be reliably detected, so that the operation timing of a gate device or the like can be accurately obtained, and a bicycle or the like passing therethrough can be detected. And the protection of users.
