Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a management system that permits parking of only a specific vehicle in a parking space for a specific vehicle, and in particular, for a specific vehicle that opens or closes the parking space based on vehicle information obtained via wireless communication. The present invention relates to a parking space management system.
[0002]
[Prior art and problems to be solved by the invention]
In general, parking spaces for disabled people are provided in public parking lots or private parking lots from the standpoint of protecting disabled people. And most of the parking spaces are arranged in a space larger than a normal parking space near the facility for the convenience of getting on and off the disabled.
[0003]
However, especially when the parking lot is crowded, it is often the case that unhealthy healthy people park in the parking space dedicated to such disabled people and the true disabled people cannot use the parking space. Yes. In addition, such a problem occurs not only in the parking space dedicated to the handicapped person, but also in a parking space that is originally allowed to park only a specific vehicle such as a contract vehicle or an emergency vehicle.
[0004]
Then, an object of this invention is to provide the parking space management system which opens or closes the parking space so that only a specific vehicle can park in the special parking space for specific vehicles.
[0005]
[Means for Solving the Problems]
In view of the above problems, the invention described in claim 1 is directed to a specific vehicle parking space management system (hereinafter simply referred to as “management system”) for permitting the specific vehicle parking space to be parked only by a specific vehicle on which a disabled person gets. that provides referred to as).
[0006]
Specifically, the present management system includes a parking space opening / closing means that is opened to allow entry of a specific vehicle into a specific vehicle parking space and is closed to prevent entry of a non-specific vehicle, and a specific vehicle. A fixed communication device that is arranged in a parking space for a vehicle and communicates with a vehicle-mounted communication device provided as a part of a license plate of a specific vehicle via a wireless signal, and parking that controls opening and closing of the parking space opening and closing means Space opening / closing control means.
[0007]
As the parking space opening / closing means, for example, a gate that is provided around the parking space (usually in front) and moves up and down according to whether the vehicle is allowed to enter or not is opened, and the gate is driven. However, it is not such a gate type, but it is like a car stop that opens or closes the parking space by sinking on the road surface or protruding from the road surface depending on whether the vehicle is allowed to enter. It may be anything.
[0008]
When the fixed communication device receives information from the in-vehicle communication device that the vehicle about to enter the parking space for the specific vehicle is the specific vehicle, the parking space opening / closing control means Opening and closing means is opened to allow entry of specific vehicles. On the other hand, when a specific vehicle that has once entered the parking space for the specific vehicle enters the parking space, the parking space opening / closing control means closes the parking space opening / closing means to prevent the non-specific vehicle from entering. Specifically, the in-vehicle communication device stores license plate information indicating a vehicle number and personal information that can be used to identify a person with a physical disability as information under government control. The device receives the personal information as information indicating that the vehicle is the specific vehicle.
[0009]
As described above, in this management system, data communication is performed between the fixed communication device and the in-vehicle communication device, and it is confirmed that the vehicle trying to enter the parking space for the specific vehicle is a specific vehicle by this communication. The parking space is only opened if Further, when it is confirmed that the specific vehicle has entered from the parking space, the parking space is automatically closed. For this reason, it is possible to avoid a situation in which a person other than the disabled person parks his / her non-specific vehicle without permission in the parking space. In addition, since communication between the fixed communication device and the in-vehicle communication device is automatically performed via wireless, the disabled person does not need to perform a special operation, and the management system is smoothly operated.
In particular, in this management system, since the in-vehicle communication device is provided as a part of the license plate of the specific vehicle, the in-vehicle communication device does not occupy the vehicle space as a special in-vehicle device and is installed in the vehicle. It is reasonable without having to consider the location. In addition, since the license plate is issued and managed by the Land Transport Bureau, which is a government administrative organization, information on the status of persons with disabilities can be incorporated under government official recognition. Since the identification code and the identification code of the handicapped person can be under the control of the government, the information indicating that the vehicle is a specific vehicle can be given public reliability. In consideration of the convenience of a government administrative organization or the like, it may not be preferable to rewrite information as a specific vehicle as needed. In this case, the license plate may be issued in a state where the in-vehicle communication device in which the vehicle information, the handicapped person information, etc. are written in advance in the storage area is incorporated in the license plate. In this case, the in-vehicle communication device is configured as a read-only device.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below with reference to the drawings.
In this embodiment, the parking space management system for specific vehicles of the present invention (simply referred to as “management system”) is applied to the management of a parking space exclusively for disabled persons (simply referred to as “exclusive space”). It is a conceptual diagram of the said management system.
[0026]
As shown in FIG. 1, the management system according to the present embodiment is a system that parks only a vehicle for disabled persons (simply referred to as “exclusive vehicle”) 2 in a dedicated space 1. 3 is provided. When it is confirmed that the vehicle to enter the dedicated space 1 is a dedicated vehicle, the gate 3a is raised to allow entry of the vehicle (FIG. 1 (a)), confirming that the vehicle is a dedicated vehicle. If not, the vehicle 3 is prevented from entering while the gate 3a is lowered. Whether or not the vehicle to enter the dedicated space 1 is the dedicated vehicle 2 is confirmed between the fixed communication device 5 installed in the gate device 3 and the in-vehicle communication device 6 mounted in the dedicated vehicle 2. The data communication process is performed.
[0027]
As shown in FIG. 1, the fixed communication device 5 is disposed in the front region of the gate device 3, and an activation signal for activating the in-vehicle communication device 6 mounted on the dedicated vehicle 2 from the antenna 11. As a result, pilot signals (for example, 10) are periodically transmitted. Then, when the dedicated vehicle 2 enters a communication area, which will be described later, capable of communicating with the fixed communication device 5, the in-vehicle communication device 6 is automatically started, and after the start, by a command from the fixed communication device 5 side, For example, predetermined communication necessary for management of the parking space is performed such that system ID, vehicle license plate information, handicapped person registration information and the like, which will be described later, are transmitted from the in-vehicle communication device 6 side.
[0028]
On the other hand, as shown in FIGS. 1 and 2, the in-vehicle communication device 6 is provided as a part of a license plate 10 in front of the vehicle. That is, the in-vehicle communication device 6 is configured by arranging, for example, a metal plate-like antenna on the upper surface of a substrate on which a communication circuit is arranged, and housing these in a thin plate-shaped housing made of resin. The plate 10 is fitted and fixed in a through hole 10 a provided in the plate 10. In order to visually recognize that the vehicle is for a disabled person, a disabled person mark 6 a may be attached to the front surface of the in-vehicle communication device 6.
[0029]
And the radio | wireless module registration information shown in FIG. 3 is memorize | stored in the memory | storage device which is not shown in figure which comprises the communication circuit of the vehicle-mounted communication apparatus 6. FIG. The radio wave module registration information is registration information of the dedicated vehicle 2 transmitted from the in-vehicle communication device 6 at the time of communication with the fixed communication device 5. For example, license plate information indicating a vehicle number, passenger personal information, and the like Has been written. For example, as shown in FIG. 3, the predetermined bit of the data for transmission is set to “1” when the person is disabled so that the personal information can be identified as disabled. It can be stored as “0”. In this case, the present management system identifies the radio wave module registration information transmitted from the in-vehicle communication device 6 by the fixed communication device 5 and only confirms that the predetermined bit is “1”. Will be released. Needless to say, as personal information, not only such disabled person registration information but also various information can be registered.
Here, the in-vehicle communication device 6 can be provided as a part of at least one of the license plate of the specific vehicle and the vehicle verification slip of the specific vehicle. If comprised in this way, the vehicle-mounted communication apparatus 6 does not occupy a vehicle space as a special vehicle-mounted apparatus, and it is rational without having to consider the installation position etc. to a vehicle. In addition, considering the fact that license plates are usually issued and managed by the Land Transport Bureau, which is a government administrative institution, the above personal information (the bit is 1) that identifies a specific person such as a disabled person Can be performed under government official recognition, and for example, a vehicle identification code and a specific person identification code can be under government control. Accordingly, it is possible to give official reliability to the information that the vehicle is a specific vehicle.
[0030]
Next, the configuration of the fixed communication device 5 and the in-vehicle communication device 6 constituting the management system will be described with reference to FIG. FIG. 4A is a block diagram illustrating the configuration of the fixed communication device 5, and FIG. 4B is a block diagram illustrating the configuration of the in-vehicle communication device 6. In order to perform communication as described above, data is transmitted between the fixed communication device 5 side and the communication antenna 11 via the antenna 11 and the in-vehicle communication device 6 as shown in FIG. A data transmission / reception unit 12 for performing communication, and a communication control unit 13 for controlling the data transmission / reception unit 12 to transmit / receive predetermined data for managing the dedicated space 1 are provided. A gate driving means 14 such as an actuator for driving opening and closing of the gate 3a in front of the dedicated space 1 is connected according to a command from the communication control unit 13.
[0031]
On the other hand, on the side of the in-vehicle communication device 6 mounted on the dedicated vehicle 2, as shown in FIG. 4 (b), a communication antenna 21 and a power source 22 that generates a constant power source voltage (supplied from the in-vehicle battery). The data transmission / reception unit 24 that operates by receiving power supply from the power supply unit 22 through the power switch 23 and performs data communication with the fixed communication device 5 through the antenna 21. The communication control unit 25 operates by receiving power supply from the power supply unit 22 through the power switch 23 and controls the data transmission / reception unit 24 to transmit / receive predetermined data, and the power supply unit 22 directly supplies power. It is always operated by receiving the supply, and the dedicated vehicle 2 (that is, the in-vehicle communication device 6) is in a communication area in which data communication with the fixed communication device 5 is possible based on the received signal from the antenna 21. It is determined whether Tsu, by turning on the power switch 23 upon entering the communication area, and the start determination unit 26 to start the data transmission / reception unit 24 and a communication control unit 25 is provided.
[0032]
Here, the communication control units 13 and 25 provided in the fixed communication device 5 and the in-vehicle communication device 6 are each configured by a one-chip microcomputer including a CPU, a ROM, a RAM, and the like. And the communication control part 13 by the side of the fixed communication apparatus 5 not only performs the data communication between the vehicle-mounted communication apparatuses 6, but every fixed time (10 msec. In a present Example) for a fixed time (in a present Example). 1 msec.), A pulse signal of 10 kHz (1 cycle: 0.1 msec.) Is output to the data transmission / reception unit 12, so that the pulse signal is transmitted from the data transmission / reception unit 12 via the antenna 11. Send the corresponding outgoing signal. In other words, from the antenna 11 on the fixed communication device 5 side, the transmission radio wave is transmitted every 10 msec. For 10 msec. At intervals of 0.05 msec. The transmitted radio wave becomes a pilot signal (that is, a start signal) for starting the internal circuit (that is, the data transmission / reception unit 24 and the communication control unit 25) of the in-vehicle communication device 6. In addition, a signal for data communication is also transmitted and received between the fixed communication device 5 and the in-vehicle communication device 6, but this signal is modulated by serial data generated in synchronization with a 100 kHz transmission clock. It changes faster than the pilot signal.
[0033]
On the other hand, on the in-vehicle communication device 6 side, the activation determination unit 26 receives the pilot signal transmitted as described above from the fixed communication device 5 side, and the in-vehicle communication device 6 communicates with the fixed communication device 5. When it is determined that a possible communication area has been entered, the power switch 23 is turned on to supply the power supply voltage to the communication control unit 25 and the data transmission / reception unit 24 to start the operation.
[0034]
Next, a specific method for managing the dedicated space 1 will be described with reference to FIG.
In FIG. 5, a region indicated by a two-dot chain line is a communication area between the fixed communication device 5 and the in-vehicle communication device 6, and is a predetermined centered on the antenna 11 of the fixed communication device 5 installed on the right front side of the dedicated space 1. The sector area is set as the communication area.
[0035]
In this communication area, the above-described pilot signal is transmitted from the antenna 11 on the fixed communication device 5 side. When the dedicated vehicle 2 enters the communication area, the in-vehicle communication device 6 is activated, and the in-vehicle communication device 6 transmits predetermined radio wave module registration information in response to a request from the fixed communication device 5 (FIG. 5A )).
[0036]
And if the fixed communication apparatus 5 confirms that the said vehicle is the exclusive vehicle 2 from this radio wave module registration information, it will drive the gate drive means 14 and will open the gate 3a. Thus, the exclusive vehicle 2 can enter the exclusive space 1 and park it (FIGS. 5B and 5C).
[0037]
On the other hand, when the dedicated vehicle 2 enters from the dedicated space 1, the parking space is managed in the reverse procedure. That is, while the dedicated vehicle 2 is parked in the dedicated space 1, the gate remains open (see FIG. 5C), but when the dedicated vehicle 2 enters the dedicated space 1, And since the said vehicle passes a communication area again, communication is performed again between the vehicle-mounted communication apparatus 6 and the fixed communication apparatus 5 at this time. When the radio wave module registration information transmitted from the in-vehicle communication device 6 determines that the vehicle passing through the communication area is the same as the vehicle that has just entered the dedicated space 1, the fixed communication device 5 Judging from the exclusive space 1. When the fixed communication device 5 makes such a determination, it sends a command to the gate drive means to close the gate, and the gate is closed (see FIG. 5A). Thereafter, the gate is kept closed until another dedicated vehicle enters the communication area again.
[0038]
Next, the management processing of the dedicated space 1 executed by the communication control unit of the fixed communication device 5 and the in-vehicle communication device 6 will be described in detail along the flowchart shown in FIG.
First, when the in-vehicle communication device 6 is activated in response to a pilot signal transmitted from the fixed communication device 5 in a predetermined communication area (S110, S310), the in-vehicle communication device 6 itself becomes the main communication device 5 with respect to the fixed communication device 5. A system ID indicating the user of the management system is transmitted (S320). The fixed communication device 5 determines whether or not this system ID has been received (S120). If the fixed communication device 5 does not determine that the system ID has been received (S120: NO), the communication is interrupted and communication with the in-vehicle communication device 6 is performed. No further communication is performed. This is to avoid power consumption due to execution of unnecessary processing on the fixed communication device 5 side, power consumption due to unnecessary information transmission on the vehicle-mounted communication device 6 side, and the like.
[0039]
If it is determined in S120 that the system ID has been received (S120: YES), the fixed communication device 5 authenticates the system ID (S130). When the system ID is authenticated (S140: YES), the fixed communication device 5 requests the in-vehicle communication device 6 for radio wave module registration information, that is, vehicle license plate information and disabled person registration information. (S150). In-vehicle communication device 6 transmits its radio wave module registration information to fixed communication device 5 in response to this request (S330).
[0040]
Then, the fixed communication device 5 determines whether or not the radio wave module registration information has been received (S160). If it is determined that the radio communication module registration information has been received (S160: YES), the registration information is authenticated (S170). In this authentication, it is determined whether information indicating that the person is disabled is written in the information written in the radio module registration information (S180). If it is determined that information indicating that the person is disabled is written (S180: YES), whether or not the registration information of the dedicated vehicle that has been entered last time remains (that is, the current dedicated space 1 has another information). Whether or not the dedicated vehicle is parked) is determined (S190), and if it is determined that no registration information remains (S190: NO), the current radio wave module registration information is set to a predetermined value for determination in the next S190. After storing in the storage area, a drive command is issued to the gate drive means 14 to open the gate 3a (S200, S210). In this way, it is possible to enter and park the exclusive vehicle 2 in the exclusive space 1.
[0041]
On the other hand, if it is determined in S190 that the registration information remains (S190: YES), the fixed communication device 5 reads the registration information stored in a predetermined storage area and compares it with the current radio wave module registration information. (S220).
Then, it is determined whether or not both registered information to be matched match (that is, whether or not they belong to the same vehicle) (S230). If it is determined that they match (S230: YES), the dedicated entry that was entered earlier It is determined that the vehicle 2 has entered, and a drive command is issued to the gate drive means 14 to close the gate 3a (S240).
[0042]
In the comparison in S220 and S230, it is determined whether the dedicated vehicle 2 that has entered the communication area this time is a dedicated vehicle that has just entered the dedicated space 1 or is another dedicated vehicle. This is to prevent the gate 3a from being opened and closed when another dedicated vehicle has passed through the communication area while the dedicated vehicle is already parked in the dedicated space 1.
[0043]
Then, after the gate is closed, the dedicated vehicle registration information stored in the predetermined storage area is deleted for the next determination in S190 (S250).
According to the management system of the present embodiment executed by the series of operations described above, only when it is confirmed that the vehicle attempting to enter the dedicated space 1 is the dedicated vehicle 2, the dedicated space 1 is automatically Open. In addition, when it is confirmed that the dedicated vehicle 2 has entered from the dedicated space 1, the dedicated space 1 is automatically closed. For this reason, it is possible to avoid a situation where an unhealthy healthy person parks majestically in the parking space for such a disabled person and the true disabled person cannot use the parking space. In addition, since communication between the fixed communication device 5 and the in-vehicle communication device 6 is automatically performed via wireless communication, the management system can be smoothly operated without the need for special operations by disabled persons.
[0044]
In this embodiment, the gate driving means 14 and the gate device 3 (gate 3a) correspond to the parking space opening / closing means, and the communication control unit provided in the fixed communication device 5 corresponds to the parking space opening / closing control means and the collating means. To do. Of the processes executed by the communication control unit, the processes of S210 and S240 shown in the flowchart of FIG. 6 correspond to the process as the parking space opening / closing control means, and the processes of S220 and S230 are the processes as the collating means. Applicable.
[0045]
As mentioned above, although the Example of this invention was described, it cannot be overemphasized that embodiment of this invention can take various forms, as long as it belongs to the technical scope of this invention, without being limited to the said Example at all. Nor.
For example, in the above-described embodiment, the in-vehicle communication device 6 is configured as a part of the front license plate 10. However, it is needless to say that the in-vehicle communication device 6 may be configured as a part of the rear license plate 10. . Further, when strict directivity is given to the antenna of the in-vehicle communication device 6, the in-vehicle communication device 6 can be disposed both in front and rear. In this case, it is convenient because the dedicated vehicle 2 can enter the dedicated space 1 from the front or the back (back). However, in this case, since there are a plurality of transmission sources from the dedicated vehicle 2, it is conceivable that misidentification occurs when the dedicated vehicle 2 enters and leaves the dedicated space 1. In order to avoid this, it is necessary that the fixed communication device 5 can clearly determine which side of the dedicated vehicle 2 communicates with the in-vehicle communication device 6. For this purpose, it is necessary to strictly set the directivity of radio waves received on the fixed communication device 5 side. Further, in this case, if it is configured such that the in-vehicle communication device 6 can receive a pilot signal from the fixed communication device 5 due to directivity, communication can be performed without starting one of the in-vehicle communication devices 6. This is convenient from the viewpoint of power saving.
[0046]
However, for example, if the gate is configured to be opened and closed by a plurality of communications with the in-vehicle communication device 6, it is considered unnecessary to consider such antenna directivity.
Further, as shown in FIG. 7, the in-vehicle communication device 6 may be configured by making the vehicle verification slip sticker 30 into a radio wave module. In this case, the thin plate-like housing in the above embodiment can be configured as a car verification slip sticker. Also in this case, like the above-described embodiment configured as a part of the license plate 10, the in-vehicle communication device 6 does not occupy the vehicle space as a special in-vehicle device, and it is also necessary to consider the installation position on the vehicle. Not reasonable. And since it arrange | positions in a vehicle interior, the vehicle-mounted communication apparatus 6 is not exposed to a wind and rain, and the effect that the lifetime of the vehicle-mounted communication apparatus 6 becomes long is also acquired.
[0047]
Further, in the above-described embodiment, the personal information as a disabled person is stored in a predetermined storage area in the in-vehicle communication device 6 in advance, but the IC card device 40 as shown in FIG. 8 is installed in the vehicle. By doing so, it is good also as a structure which transmits the information to the effect that it is an exclusive vehicle from the vehicle-mounted communication apparatus 6 by inputting the personal information that it is a handicapped at any time. In this case, the handicapped person is not recognized as a dedicated vehicle unless he / she inputs information indicating that he / she is handicapped by passing the registered IC card 41 certifying that he / she is handicapped through the IC card reader 42. It will be. Or it is good also as a structure which inputs disabled person information by the input from a key input device instead of such an IC card apparatus 40. FIG. In this case, it may be configured such that information indicating that the person is disabled can be input by inputting a password in advance. In this way, there is no problem that another person who cannot input information indicating that he / she is physically disabled uses the vehicle illegally and parks the vehicle in the exclusive space 1.
[0048]
Further, in the above-described embodiment, in S190 of FIG. 6, the determination as to whether or not the dedicated vehicle is parked in the dedicated space 1 is collated with the vehicle registration information received when the dedicated vehicle enters first. Although it went, it is also possible to make it the structure which detects the presence or absence of the vehicle in the said parking space with a sensor. In this case, the gate driving means is driven and the gate is closed when the sensor detects that no vehicle is present in the dedicated space 1. In this way, although it is necessary to install a separate sensor, the control process can be further simplified.
