DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle monitoring system for monitoring vehicles in a parking lot.

[0002]

Conventionally, as a vehicle monitoring system for monitoring vehicles in a parking lot, for example, Japanese Unexamined Patent Publication No. Hei 10-230830 discloses an abnormality (for example, unnatural shaking) in a vehicle. Then, a configuration in which an in-vehicle camera mounted on the vehicle captures an image around the vehicle is disclosed. According to this method, the user who is the owner of the vehicle or the parking lot manager not only knows that the vehicle has an abnormality, but also looks at the image taken by the on-board camera to detect the abnormality. It is possible to know the situation around the vehicle that has occurred.

However, in such a configuration in which the vehicle-mounted camera captures an image around the vehicle, an area where the vehicle-mounted camera generally cannot capture images (a so-called blind spot) is wide, so that the area around the vehicle in which an abnormality has occurred is located. There has been a problem that the situation may not be properly notified in some cases.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to appropriately notify a situation around a vehicle in which an abnormality has occurred when an abnormality occurs in a vehicle in a parking lot. It is to provide a vehicle monitoring system that can perform the monitoring.

[0005]

According to the vehicle monitoring system of the present invention, an abnormality occurrence signal indicating that an abnormality has occurred in the vehicle from the vehicle and a parking position signal indicating the position of the vehicle are received. When received by the means, the abnormality occurrence detecting means detects that an abnormality has occurred in the vehicle in the parking lot, and the position specifying means specifies the position of the vehicle in which the abnormality has occurred. When the abnormality occurrence detecting means detects that an abnormality has occurred in the vehicle in the parking lot, the photographing direction control means controls the photographing direction of the photographing means to the direction of the position specified by the position specifying means.

That is, when an abnormality occurs in the vehicle in the parking lot, the photographing means controls the photographing direction of the vehicle in which the abnormality has occurred so that the photographing means photographs the vehicle in which the abnormality has occurred. Therefore, compared to the conventional camera in which the on-board camera captures the surroundings of the vehicle, the area that cannot be captured (so-called blind spot) can be reduced,
This makes it possible to appropriately notify the situation around the vehicle in which the abnormality has occurred.

According to the vehicle monitoring system of the second aspect, when sound is generated in the parking lot and the sound is collected by the sound collecting means having directivity, the abnormality occurrence detecting means sets the vehicle in the parking lot. Detects that an abnormality has occurred,
Identify the position of the vehicle where the abnormality occurred. When the abnormality occurrence detecting means detects that an abnormality has occurred in the vehicle in the parking lot, the photographing direction control means controls the photographing direction of the photographing means to the direction of the position specified by the position specifying means.

That is, also in this case, the above-mentioned claim 1
In the same manner as described in the above, when an abnormality occurs in the vehicle in the parking lot, the photographing unit controls the photographing direction of the photographing unit to the direction of the position of the vehicle in which the abnormality has occurred, so that the photographing unit , You can reduce the area that cannot be photographed,
It is possible to appropriately notify the situation around the vehicle in which the abnormality has occurred.

According to the vehicle monitoring system of the present invention, a plurality of photographing means are provided so as to photograph the vehicle from multiple directions, so that the area where photographing is impossible can be further reduced. In addition, the situation around the vehicle in which the abnormality has occurred can be more appropriately (in detail) notified.

According to the vehicle monitoring system of the present invention, the vehicle advance control means attempts to advance from the parking lot when the abnormality occurrence detecting means detects that an abnormality has occurred in the vehicle in the parking lot. Since control is performed so that the vehicle does not advance, for example, in the event of a collision accident between vehicles or artificial mischief, etc., a collision accident may be prevented by prohibiting the vehicle from entering the parking lot. It is possible to prevent a person who wakes up or mischief from getting on the vehicle from the parking lot and fleeing.

According to the vehicle monitoring system of the fifth aspect, the abnormality-occurring vehicle feature recognizing means detects the occurrence of an abnormality in the vehicle in the parking lot and detects the abnormality. The feature of the vehicle is recognized, and the advanced vehicle feature recognition means recognizes the feature of the vehicle to be advanced from the parking lot. Then, the vehicle advance control means, if the characteristics of the vehicle to be advanced from the parking lot recognized by the advanced vehicle characteristic recognition means do not match the characteristics of the vehicle recognized by the abnormality occurrence vehicle characteristic recognition means, from the parking lot. The advance of the vehicle to be advanced is permitted, whereas the characteristic of the vehicle to be advanced from the parking lot recognized by the advanced vehicle characteristic recognition means is the characteristic of the vehicle recognized by the abnormality occurrence vehicle characteristic recognition means. , The control is performed such that the advance of the vehicle that intends to advance from the parking lot is prohibited.

Therefore, it is possible to prevent inconvenience from reaching a person who is unlikely to have caused a contact accident or a person who is unlikely to have performed mischief, and minimize the range in which the inconvenience is caused. Can be limited to
Only persons likely to have caused a contact accident or mischief can be detained in the parking lot.

According to the vehicle monitoring system of the present invention, the vehicle entry control unit attempts to enter the parking lot when the abnormality detection unit detects that an abnormality has occurred in the vehicle in the parking lot. Control is performed so that vehicles are not allowed to enter.For example, in the event of a collision accident between vehicles or artificial mischief, entry of vehicles that attempt to enter the parking lot is prohibited, so that vehicles When performing a task to verify the situation of a contact accident or mischief, or to investigate a person who caused a contact accident or performed a mischief,
It is possible to prevent confusion caused by a vehicle that subsequently enters the parking lot.

According to the vehicle monitoring system of the present invention, when the abnormality occurrence detecting means detects that an abnormality has occurred in the vehicle in the parking lot, the abnormality-occurring vehicle characteristic recognizing means detects the abnormality. The feature of the vehicle is recognized, and the approaching vehicle feature recognizing means recognizes the feature of the vehicle to enter the parking lot. If the characteristics of the vehicle entering the parking lot recognized by the entering vehicle characteristic recognition means do not match the characteristics of the vehicle recognized by the abnormal vehicle characteristic recognition, the vehicle entrance control means enters the parking lot. The approaching vehicle is permitted to enter, and the characteristic of the vehicle attempting to enter the parking lot recognized by the entering vehicle characteristic recognizing means matches the characteristic of the vehicle recognized by the abnormal vehicle characteristic recognition. Then, control is performed such that entry of a vehicle that attempts to enter the parking lot is prohibited.

[0015] Therefore, when verifying the situation of a collision accident or mischief between vehicles, or investigating a person who has caused a collision accident or a person who has mischief, troublesome persons may be troubled. This can be avoided beforehand, and the range of inconvenience can be minimized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment A first embodiment of the present invention will be described below with reference to FIGS. First, FIG. 1 schematically shows the overall configuration of the vehicle monitoring system. In the vehicle monitoring system 1, in a parking lot P where the vehicle 2 is parked, four parking vehicle monitoring cameras 3 to 6 (photographing means in the present invention) for photographing the vehicle 2 in the parking lot P, a parking lot An incoming vehicle monitoring camera 7 for capturing the vehicle 2 that is to enter the parking lot P, and an advanced vehicle monitoring camera 8 for capturing the vehicle 2 that is entering the parking lot P are installed. The parked vehicle monitoring cameras 3 to 6, the entering vehicle monitoring camera 7, and the entering vehicle monitoring camera 8 have a well-known zoom function, automatic focusing function, and the like.

At the entrance G1 of the parking lot P, an openable gate 9 is installed. When the entrance gate 9 is open, the vehicle 2 is allowed to enter the parking lot P. On the other hand, when the entrance gate 9 is in the closed state, entry into the parking lot P is prohibited. In addition, parking lot P
An opening / closing entrance gate 10 is installed at the entrance G2 of the vehicle 2. When the entrance gate 10 is in an open state, the vehicle 2 is allowed to advance from the parking lot P. When 10 is in the closed state, entry from the parking lot P is prohibited.

The management terminal 11 (abnormality detecting means, position specifying means, photographing direction controlling means, vehicle advance control means, abnormal vehicle characteristic recognizing means, advanced vehicle characteristic recognizing means, vehicle entering control means, entering vehicle The feature recognizing means) is installed, for example, in a management facility (not shown) adjacent to the parking lot P, and is mainly composed of, for example, a well-known personal computer terminal. The management terminal 11 includes the above-described parked vehicle monitoring cameras 3 to 6, the entering vehicle monitoring camera 7, the entering vehicle monitoring camera 8, and the entrance gate 9.
Also, by being connected to the entry gate 10 through, for example, a coaxial cable 12, various signals are transmitted and received.

In such a configuration, the management terminal 11 can control the photographing directions of the parked vehicle monitoring cameras 3 to 6 by transmitting the photographing direction control signals to the parked vehicle monitoring cameras 3 to 6. ing. In this case, the management terminal 1
In the normal state (a situation where no abnormality has occurred in the vehicle 2 in the parking lot P), for example, control is performed such that the photographing directions of the parked vehicle monitoring cameras 3 to 6 are shifted by a predetermined angle in predetermined time units. Thereby, the parked vehicle monitoring cameras 3 to 6 are controlled such that the entire parking lot P is photographed in chronological order.

It should be noted that the management terminal 11 basically captures only the vehicle 2 that the entering vehicle monitoring camera 7 intends to enter into the parking lot P with respect to the entering vehicle monitoring camera 7 and the entering vehicle monitoring camera 8. It is sufficient that the advanced vehicle monitoring camera 8 captures only the vehicle 2 that is going to advance from the parking lot P. Therefore, unlike the above-described parked vehicle monitoring cameras 3 to 6, the capturing direction is controlled. Never.

When the entrance gate 9 detects that the vehicle 2 has approached (stopped just before the entrance gate 9) by, for example, a proximity sensor (not shown) disposed in the vicinity,
The vehicle 2 is opened and the vehicle 2 is opened under the condition that the condition that the vehicle 2 can enter the parking lot P is satisfied (for example, the physical length, width, height, and the like of the vehicle are within the limit values). Is detected to have passed through the entrance gate 9, it is closed. At this time, the approaching vehicle monitoring camera 7 captures an image of the vehicle 2 that is about to enter the parking lot P, and transmits an image signal including the captured image to the management terminal 11.

When the entrance gate 10 detects that the vehicle 2 has approached (stopped just before the entrance gate 10) by, for example, a proximity sensor (not shown) disposed in the vicinity, the entrance gate 10 moves the vehicle 2 to the parking lot P. The conditions that can be entered from are satisfied (for example, parking fees are collected properly)
Is open and the vehicle 2 is in the entry gate 1
When it detects that it has passed zero, it is closed. At this time, the advanced vehicle monitoring camera 8 captures an image of the vehicle 2 that is about to advance from the parking lot P, and transmits an image signal including the captured image to the management terminal 11.

The entrance gate 9 and the entrance gate 10 are
Apart from the opening / closing operation using such a proximity sensor, as described later in detail, when an abnormality occurs in the vehicle 2 in the parking lot P, priority is given to the opening / closing operation based on the proximity sensor, The opening / closing operation is performed based on an opening / closing instruction from the management terminal 11. That is, the management terminal 1
1 can forcibly open the entrance gate 9 and the entrance gate 10 by transmitting an opening signal to the entrance gate 9 and the entrance gate 10, and transmit a closing signal to the entrance gate 9 and the entrance gate 10. By transmitting, the entrance gate 9 and the exit gate 10 can be forcibly closed.

The vehicle 2 has an on-board terminal 13 mounted thereon. The in-vehicle terminal 13 has a GPS receiver for receiving GPS radio waves from the GPS satellites 14, and can calculate the current position by extracting and calculating various parameters from the GPS radio waves received from the GPS satellites 14. It has become. Further, the in-vehicle terminal 13 includes, for example, a shaking detection sensor that detects shaking of the vehicle 2, a contact detecting sensor that detects contact with another vehicle 2, a human body, a stone, or the like, a pneumatic sensor that detects tire pressure, and the like. It is detected whether an abnormality has occurred in the vehicle 2.

When the in-vehicle terminal 13 detects that an abnormality has occurred in the vehicle 2 due to input of detection signals from the motion detection sensor, the contact detection sensor, the air pressure sensor, and the like, the abnormality occurs in the vehicle 2. The service center 15 (signal receiving means according to the present invention) transmits an abnormality occurrence signal indicating the occurrence of the abnormality through a telephone network including a mobile telephone network and a fixed telephone network.
And the GP received from the GPS satellites 14
The current position is calculated based on the S radio wave, and the calculated current position, that is, a parking position signal indicating the position of the vehicle 2 is transmitted to the service center 15 through the telephone network. At this time, the on-board terminal 13 stores the registration number (vehicle number) of the vehicle 2.
Is transmitted to the service center 15 through the telephone network. Note that the above-mentioned in-vehicle terminal 13 may be a dedicated terminal or may be substituted by a known car navigation device.

Next, the operation of the above configuration will be described with reference to FIG.
This will be described with reference to FIG. Here, FIG. 2 shows, as a sequence diagram, transmission and reception of various signals performed between the on-board terminal 13, the service center 15, the parked vehicle monitoring cameras 3 to 6, and the management terminal 11. FIG.
FIG. 4 shows, as a flowchart, the contents of the processing performed by the service center 15, and FIG. 4 shows, as a flowchart, the contents of the processing performed by the management terminal 11. Also,
Here, a case where a collision accident between vehicles occurs in the parking lot P will be described.

The management terminal 11 normally monitors the entering vehicle when the vehicle 2 attempts to enter the parking lot P (normally, when no abnormality occurs in the vehicle 2 in the parking lot P). When an image signal including an image captured by the approaching vehicle monitoring camera 7 is received from the camera 7, the received image signal, that is, the image of the vehicle 2 entering the parking lot P is displayed. By analyzing the parking lot P
Data relating to the vehicle 2 about to enter the vehicle, specifically, the registration number and characteristics (shape, color, etc.) of the vehicle 2 are shown in FIG.
As shown in (1), it is stored as a parked vehicle database.

Also, the management terminal 11 usually has the vehicle 2
When an image signal containing an image captured by the advanced vehicle monitoring camera 8 is received from the advanced vehicle monitoring camera 8 with the attempt to advance from the parking lot P, the received image signal, By analyzing an image showing the vehicle 2 that is going to enter the parking lot P, data on the vehicle 2 that is going to enter the parking lot P is deleted from the parked vehicle database described above.

Now, a case where a collision accident between vehicles occurs in the parking lot P will be described. In-vehicle terminal 13 mounted on vehicle 2 involved (touched) in a contact accident
As described above, when a detection signal is input from a motion detection sensor, a contact detection sensor, a pneumatic sensor, or the like, when the fact that the user is involved in a contact accident is detected, an abnormality that indicates that the user is involved in a contact accident occurs. A signal, a parking position signal indicating the position of the vehicle 2 and a registration number signal indicating the registration number of the vehicle 2 are transmitted to the service center 15 through the telephone network.

When the service center 15 receives the abnormality occurrence signal, the parking position signal, and the registration number signal from the onboard terminal 13 ("YES" in step S1 in FIG. 3).
By analyzing the parking position signal, the position of the parking lot where the vehicle 2 involved in the contact accident exists is specified (FIG. 3).
Middle, step S2). Here, the reason why the service center 15 specifies the position of the parking lot is as follows. That is, in the present embodiment, the description has been given on the premise that the system configuration includes one parking lot P and one management terminal 11. However, when the system configuration includes a plurality of parking lots P, the service center 15 is used. Receives the abnormality occurrence signal, the parking position signal, and the registration number signal from the plurality of parking lots P, and it is necessary to specify any one of the parking lots P in which the contact accident has occurred from the plurality of parking lots P. is there.

Then, the service center 15 transmits the abnormality occurrence signal, the parking position signal and the registration number signal received from the in-vehicle terminal 13 to the management terminal 11 (step S3 in FIG. 3).

When the management terminal 11 receives the abnormality occurrence signal, the parking position signal and the registration number signal from the service center 15 ("YES" in step T1 in FIG. 4).
By analyzing the parking position signal, the position of the vehicle 2 involved in the contact accident in the parking lot P is specified (FIG. 4).
Middle, step T2). Next, the management terminal 11 transmits the shooting direction control signal to the parked vehicle monitoring cameras 3 to 6 to control the shooting direction of the parked vehicle monitoring cameras 3 to 6 to the direction of the specified position (in FIG. 4). , Step T
3).

More specifically, as shown in FIG. 6, the management terminal 11 normally has the parked vehicle monitoring cameras 3-6.
Is controlled so as to reduce the overlap of the photographing ranges (to secure a wide photographing range as a whole). However, when a collision accident occurs between vehicles, as shown in FIG. Then, the photographing direction of the parked vehicle monitoring cameras 3 to 6 is controlled to the direction of the position where the contact accident has occurred. As a result, the vehicle 2 involved in the contact accident is photographed by the parked vehicle monitoring cameras 3 to 6 from multiple directions. still,
In FIGS. 6 and 7, the shooting ranges of the parked vehicle monitoring cameras 3 to 6 are respectively indicated by two-dot chain lines a1 to a2, b1 to b2, and c.
1 to c2 and d1 to d2. 6 and 7, the entrance G1 and the entrance G2
Is omitted.

As described above, in the vehicle monitoring system 1, for example, when a collision accident occurs between vehicles, the photographing directions of the parked vehicle monitoring cameras 3 to 6 are controlled to the direction of the position where the collision accident occurred. This allows the parked vehicle monitoring cameras 3 to 6 to photograph the vehicle 2 involved in the contact accident.

Now, when the management terminal 11 receives an image signal including an image captured by the parked vehicle monitoring cameras 3 to 6 from the parked vehicle monitoring cameras 3 to 6 (in FIG. 4,
Step T4) By analyzing the received image signal, that is, the image showing the vehicle 2 involved in the contact accident, the features of the vehicle 2 that has caused the contact accident are recognized and stored (FIG. 4). , Step T5).

Next, when the management terminal 11 detects that the vehicle 2 is about to advance from the parking lot P by receiving the image signal from the advanced vehicle monitoring camera 8 (step T6 in FIG. 4), the management terminal 11 receives the image signal. The analyzed image, that is, the image showing the vehicle 2 that is going to advance from the parking lot P is analyzed, and the characteristics of the vehicle 2 that is going to advance from the parking lot P are recognized by referring to the parked vehicle database. It is stored (step T7 in FIG. 4). And the management terminal 1
1 compares the characteristics of the vehicle 2 that has caused the contact accident, which has been previously recognized and stored, with the characteristics of the vehicle 2 that is about to enter the parking lot P (step T8 in FIG. 4).

Here, when the characteristics of the two terminals match ("YES" in step T8 in FIG. 4), the management terminal 11 transmits the closing signal to the entry gate 10 to forcibly reset the entry gate 10. Close (Step T in FIG. 4)
9). Accordingly, thereafter, the vehicle 2 having the contact accident or the vehicle 2 having the same characteristics as the vehicle 2 having the contact accident is prohibited from entering the parking lot P.
If the characteristics do not match ("NO" in step T8 in FIG. 4), the management terminal 11 does not transmit the closing signal to the entrance gate 10, and the entrance gate 10 is normally opened and closed. Perform the operation.

By the way, the characteristics of the vehicle 2 that caused the contact accident when the contact accident between the vehicles occurred are described above.
When the characteristics of the vehicle 2 that is going to advance from the parking lot P match, by forcibly closing the entrance gate 10,
It is configured to prohibit the vehicle 2 having the contact accident or the vehicle 2 having the characteristics of the vehicle 2 having the contact accident from entering the parking lot P, but immediately after the occurrence of the contact accident. The entrance gate 10 is forcibly closed, so that all vehicles 2 that intend to advance from the parking lot P after the point of contact accident are prohibited from entering the parking lot P. It is also possible.

In addition to the opening / closing operation of the entrance gate 10, the opening / closing operation of the entrance gate 9 can be controlled, and the characteristics of the vehicle 2 that caused the contact accident and the approach to the parking lot P will be described. When the characteristics of the vehicle 2 match,
By forcibly closing the entrance gate 9, it is also possible to prohibit the vehicle 2 having the characteristics of the vehicle 2 having caused the contact accident from entering the parking lot P. And, by forcibly closing the entrance gate 9 immediately after the occurrence of the contact accident, all the vehicles 2 that are going to enter the parking lot P after the time of the occurrence of the contact accident.
However, it is also possible to prohibit entry into the parking lot P.

In the above description, the case where a collision accident between vehicles occurs in the parking lot P has been described. The same applies to the case where mischief occurs in the parking lot P. In this case, in addition to controlling the opening and closing operations of the entrance gate 9 for the vehicle 2 to enter and the entrance gate 10 for the vehicle 2 to enter, the entrance gate and the person for the person to enter on foot. If there are entry gates for the entry on foot, the opening and closing operations of those entrance gates and entry gates may also be controlled.

As described above, according to the first embodiment, in the vehicle surveillance system 1, for example, when a collision accident occurs between vehicles, the contact accidents occur in the photographing directions of the parked vehicle monitoring cameras 3 to 6. Since the parked vehicle monitoring cameras 3 to 6 are configured to photograph the vehicle 2 involved in a collision accident by controlling in the direction of the position, the vehicle-mounted cameras mounted on the vehicle photograph the surroundings of the vehicle. It is possible to reduce the area in which photographing is impossible (a so-called blind spot), thereby appropriately notifying the situation around the vehicle 2 involved in the contact accident.

Further, since the plurality of parked vehicle monitoring cameras 3 to 6 are configured to photograph the vehicle 2 from multiple directions, it is possible to reduce the area where photographing is not possible, thereby causing a collision accident. It is possible to more appropriately (detailedly) notify the situation around the vehicle 2 that has occurred.

For example, when a collision accident occurs between vehicles, the entry gate 10 is forcibly closed,
Since the vehicle 2 that attempts to advance from the parking lot P is configured to be prohibited, it is possible to prevent a person who has caused a contact accident from getting on the vehicle 2 from the parking lot P and running away. . Then, in this case, of the vehicles 2 that are going to advance from the parking lot P, the vehicle 2 that has caused the contact accident
Also, by controlling the vehicle 2 having the same characteristics as the vehicle 2 having caused the contact accident so as to prohibit the entry from the parking lot P, a person having a low possibility of having caused the contact accident can be obtained. The inconvenience can be avoided beforehand, and the extent of inconvenience can be minimized.

Further, for example, when a collision accident occurs between vehicles, the entrance gate 9 is forcibly closed,
Since the vehicle 2 that attempts to enter the parking lot P is configured to be prohibited from entering the parking lot P, when performing a task of verifying the situation of the contact accident or a task of searching for the person who caused the contact accident, it is necessary to stop afterwards. It is possible to prevent confusion caused by the vehicle 2 entering the parking lot P beforehand. In this case, the control is performed such that only the vehicle 2 having the same characteristics as the vehicle 2 that has caused the contact accident among the vehicles 2 that are going to enter the parking lot P is prohibited from entering the parking lot P. By doing so, it is possible to prevent inconvenience to a person who does not interfere at all when performing the work of verifying the situation of the contact accident or the work of investigating the person who caused the contact accident, and Can be minimized.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. In addition, the first
The description of the same parts as in the embodiment is omitted, and different parts will be described. In the first embodiment, the in-vehicle terminal 1

By specifying the position of the vehicle 2 and transmitting a shooting direction control signal to the parked vehicle monitoring cameras 3 to 6,
The photographing directions of the parked vehicle monitoring cameras 3 to 6 are controlled to the directions of the specified positions. Then, the management terminal 26 thereafter performs the same processing as in the first embodiment described above. In this case, it is not necessary for the vehicle 2 to be equipped with the in-vehicle terminal 13 described in the first embodiment.

As described above, according to the second embodiment, in the vehicle monitoring system 21, for example, when a collision accident occurs between vehicles, the microphone units 22 to 22 in which a plurality of microphones having directivity are integrated. 2
5 collects the sound, and controls the photographing direction of the parked vehicle monitoring cameras 3 to 6 in the same manner as described in the first embodiment to the direction of the position where the contact accident has occurred, thereby parking the vehicle. Since the vehicle monitoring cameras 3 to 6 take an image of the vehicle 2 involved in the contact accident, it is possible to reduce the area that cannot be photographed, and thereby, the situation around the vehicle 2 involved in the contact accident. Can be properly notified. In this case, the vehicle 2 does not need to be equipped with the in-vehicle terminal 13 described in the first embodiment, so that the overall configuration is simplified as compared with the one described in the first embodiment.
