[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic front view showing the appearance of the monitoring camera device according to the first embodiment of the present invention. The surveillance camera device has a structure particularly suitable for monitoring various indoor facilities such as convenience stores, supermarkets, rental video shops, and the like. As shown in FIG. 1, the surveillance camera device 10 includes a casing 12 and a camera unit 14 attached to a lower part of the casing 12. A display device 16 is fixed to one side (front side) of the casing 12. The surveillance camera device 10 is mounted on the rail 20 and can move along the rail 20 by a transport mechanism described later. Further, a flat cable 22 extends from the casing 12 to a cable storage case described later.

Inside the casing 12, a transport mechanism for moving the monitoring camera device 10 along the rail 20, a programming controller unit for controlling the movement, a motor control unit for controlling the transport mechanism, An integrated control unit for controlling various functions including the display device 16 is arranged. As the display device 16, for example, a liquid crystal display (LC
D) or a plasma display can be used. Although it is desirable to use a flat display, a CRT display may be used in some cases.

FIG. 2 is a schematic front view showing a state where the casing of the monitoring camera device 10 according to the present embodiment is removed, and FIG. 3 is a schematic side view thereof. As shown in FIGS. 2 and 3, a frame 24 is provided for mounting a casing and supporting various units including a transport mechanism. The frame 24 supports the transport mechanism 26 and has a housing 2 below which housing units of various substrates is accommodated.
Eight. The transport mechanism 26 moves the surveillance camera device 10 by rotating the motor 30 attached to the upper central portion of the frame, a gear mechanism 32 for transmitting the rotation of the motor 30, and the rotational force transmitted via the gear. It has a drive wheel 34 to be driven, and a driven wheel 36 disposed at a position symmetrical with the drive wheel 34. In the present embodiment, the rotation of the motor 30 is transmitted to the drive wheels 34 via the gear mechanism 32. However, the present invention is not limited to this, and the drive wheels may be directly rotated by the motor 30. Alternatively, another rotation transmission mechanism such as a belt may be used. The outer peripheries of the drive wheel 34 and the driven wheel 36 are made of urethane material, and can reliably contact the upper part of the rail 20 so that the surveillance camera device 10 can advance without slipping. Further, a DC motor or a stepping motor can be used as the motor in addition to the AC servo motor.

In the present embodiment, the cross section of the upper part of the rail 20 has a convex and smooth curve. This may be a semicircle or a part of an ellipse. Alternatively, another convex curve may be used. By making the cross-sectional shape of the rail 20 a convex curve in this way, foreign substances such as dust and water droplets hardly remain on the rail,
The surveillance camera device 10 can reliably move along the rail. In addition, since no foreign matter remains, the number of maintenance operations on the rail can be reduced.

Further, the side surfaces 38 and 40 of the upper part of the rail 20
, Three guide wheels 44, 46, 48 are arranged. Of these, the guide wheels 44 on the front side (that is, the side on which the display device is arranged) are driven by the spring mechanism described later to be on the back side (that is, the opposing wheels 46, 4
8 side). The spring mechanism allows the surveillance camera device 10 to be appropriately positioned with respect to the rail 20 when the rear-side guide wheels 46, 48 described later are attached, and when the vehicle passes through the curved rail 20, The relative position of the monitoring camera device 10 to the rail is maintained against the centrifugal force. The guide wheels 46 and 48 on the back side are fixed by screws.
By removing the screws, the guide wheels 46, 48 themselves can be removed.

Further, a lower guide wheel 52 is arranged on one side (back side) 50 of the lower part of the rail 20. In the present embodiment, the rail 20 is not limited to a straight line but may be a curved line. Therefore, when moving along a curved line, the monitoring camera device 10 may be swung in the side direction (the direction of arrow A in FIG. 3) due to the centrifugal force or the like. Such a swing is caused by the lower guide wheel 5
2 prevents it. When the rail 20 is straight, the lower guide wheel 52 may be omitted.
Also, an assist wheel 54 is arranged on the lower surface of the rail 20. The assist wheel 54 is provided to prevent the surveillance camera device 10 from coming off.

Non-contact sensors (proximity switches) 56 and 58 are mounted on the center front side of the frame 24.
The contactless sensors 56 and 58 are arranged to detect that the rail 20 is bent. In the present embodiment, magnetic sensors are used as the non-contact sensors 56 and 58. As shown in FIGS. 4A and 4B, a protrusion 62 extending in the longitudinal direction is provided on a side surface of the rail 20 at a position sandwiching a bent portion of the rail 20.
Is arranged. Therefore, the contactless sensors 56, 5
8 detects the presence of the projection 62, whereby the start and end of the curved portion can be detected.

Next, the spring mechanism of the front guide wheel 44 will be described. As shown in FIG. 5, the spring mechanism 64 has a tension spring 68 having one end fixed to the frame 24 and the other end fixed to the support member 66. The support member 66 is rotatable about a shaft 70, and the front guide wheel 44 is rotatably mounted at a position separated from the shaft 70 by a predetermined distance. Therefore, the supporting member 66 is urged in the direction of arrow C about the shaft 70 by the pulling force of the spring 68 in the direction of arrow B. As a result, the front-side guide wheel 44 can be urged against the side wall of the rail 20 and come into contact therewith.

As shown in FIG. 2, various control units are mounted on the housing 28 on the lower side of the casing 12. In the present embodiment, the supply of power to these control units and the transmission and reception of signals are performed via the flat cable 22. This is particularly advantageous in a facility where transmission and reception of signals by radio is impossible (for example, a hospital). In addition, by supplying power via a cable, it is possible to prevent time loss due to charging,
The monitoring camera device 10 can be reduced in weight.

FIG. 6 is a schematic side view showing a cable storage case 72 for storing the monitoring camera device 10 and the flat cable 22. The cable storage case 72 has a cross-sectional shape in which the upper part is opened, and extends above the rail 20 substantially parallel to the rail 20. Flat cable 2
2 is at least the extension distance of the rail 20 (ie,
Has a length of more than half of the movable distance of the monitoring camera 10),
One end thereof extends, for example, into a support (not shown) of the cable storage case 72 at the center position of the rail 20, or is connected to another signal line via a connector. On the other hand, the other end extends to the outside from the opened upper portion and is connected to a connector (not shown) of the monitoring camera device 10. Finally, the signal line is connected to a power supply device (not shown) or a monitoring console (not shown). By using a flat cable in this way, the surveillance camera device 10
However, when it is located at one end of the rail 20 (see FIG. 7A), it gradually moves to the center thereof (see FIG. 7B), and then moves toward the other end (see FIG. 7B). (See FIGS. 7 (c) and (d)), the cables are not entangled or twitched.

In this embodiment, a programming controller unit, a motor control unit, and a general control unit are arranged. These are supplied with power and control signals via the flat cable 22. The programming controller unit controls the movement of the monitoring camera device 10. In the present embodiment, the movement of the camera based on a desired sequence can be set in addition to the speed on a straight road and the speed on a curved road. The speed and the setting can be remotely controlled from a monitoring console (not shown) or the like. The motor control unit supplies a motor drive current to the motor 30 according to a speed signal or the like from the programming controller unit. The integrated control unit outputs the video signal received from the camera unit 14 to the outside via the flat cable 22 and displays the video on the screen of the display device 16 given via the flat cable 22. It receives the signal and provides it to the display device 16. When a camera control signal for controlling the direction of the lens in the camera unit 14 or controlling the zoom and focus is received via the flat cable 22, a predetermined command is issued to the camera unit 14.
Give to.

In this embodiment, the camera unit 14 can rotate at least vertically in a predetermined angle range. Further, zooming can be performed based on an instruction from the monitoring console. Further, an image based on the image signal provided via the flat cable 22 is broadcast on the display device 16. For example, in a convenience store or a supermarket, a special sale item on the day or an advertisement of a product being promoted can be broadcast. In a rental video shop, a trailer of a movie that has started rental and a movie that has been released can also be broadcast.

Next, the rail mounting structure will be briefly described. In the first embodiment, at every predetermined distance, FIG.
Are provided, and the rail is fixed to an arm extending from a predetermined position of the support. As shown in FIG. 8, the support column 74 includes a hollow cylindrical main body 80 provided with elongated shafts 76 and 78 at both ends, an upper support member 82 rotatably attached to the shaft 76, And a lower support member 84 freely attached. A screw hole is formed at a predetermined position of the main body 80, and an arm 86 having a through hole is positioned at a position matching the screw hole, and the screw 8 is formed.
By screwing 8, 90, the arm 86 can be fixed. In addition, since the upper support member 82 and the shaft 76 are attached by screwing, the vertical position of the upper support member 82 can be changed by rotating the main body 80 side. This allows the support 7 to be positioned at a desired position.
4 is arranged and the main body 80 is rotated so that the upper support member is
Make sure that the support 74 is firmly in contact with the ceiling of the facility.
Can be securely fixed.

The surveillance camera device 10 configured as described above
The arrangement of the track of the rail 20 and the like will be described below. FIG. 9A is a diagram illustrating an example in which the track of the rail 20 is arranged in the video shop, and FIG. 9B is a diagram illustrating a sequence of the moving speed of the monitoring camera device 10. For example, in a store as shown in FIG. 9A, the track of the rail 20 is linear, and the monitoring camera device 10
Reciprocate in orbit. Parallel to the track of the rail 20,
A cable storage case (not shown) is also provided. As described above, in order to arrange the track, the columns 74 are arranged along the inner wall of the facility, the arms 86 are attached to each of the columns 74, and the rails 20 are fixed to the arms 86 by screws or the like. .

For example, when the display shelf is high and the field of view from the camera unit 14 of the monitoring camera device 10 is obstructed, as shown in FIG. It is desirable to set the camera movement sequence so as to increase the moving speed of the surveillance camera and move the surveillance camera at a lower speed in other parts. Thereby, it is possible to perform appropriate monitoring by moving the monitoring camera device 10 quickly in the blind spot and slowly moving the monitoring camera device 10 in other places. Also, while the surveillance camera device 10 is moving, a video signal is given to the surveillance camera device 10, and an image based on the video signal is displayed on the screen of the display device 16. Focus on it. This makes it possible to confirm the face of the customer and the like more reliably. On the other hand, for the customer as well, rather than recognizing the surveillance camera device 10 as a “surveillance camera”, the user focuses on the image broadcast on the display device 16, so that the possibility of giving the customer a sense of oppression can be reduced. Becomes

FIG. 9C is a diagram showing an example in which the track of the rail 20 is arranged in another store, for example, a rental video shop. FIG. 9D is a diagram showing an example of a movement sequence of the monitoring camera device 10 in the arrangement shown in FIG. 9C. For example, when the height of the display shelf is relatively low and the surveillance camera device crosses the side of the display shelf, if the field of view obstructed by the display shelf is small, on a straight road,
The monitoring camera device 10 may be moved at a uniform speed (see reference numerals 901 and 902 in FIG. 9D). On the other hand,
In this example, since the orbit includes a curved road, the vicinity of both ends of the curved road region (reference numerals 910 and 911 in FIG. 9C)
), A protrusion is provided on one side surface of the rail, so that the monitoring camera device 10 can determine before and after the curved road. Therefore, as shown by reference numeral 903 in FIG. 9D, the speed when passing through a curved road is lower than that when passing through a straight road.
Further, when monitoring the vicinity of the entrance (920) of the store, as shown by reference numeral 904 in FIG. 9 (d), the speed of the monitoring camera device is further reduced, and the customer near the entrance is more reliably monitored. The sequence may be set so that it can be performed.
The setting of the movement sequence of the monitoring camera device 10, the change and stop of the speed, the change of the camera position, and the zoom can be controlled from the monitoring console or the like.

As described above, according to the present embodiment, since the surveillance camera device 10 is configured to be able to move on the track of the rail 20, the monitoring camera device 10 is appropriately monitored with a small number of blind spots using a small number of cameras. It is possible to monitor the area to be performed. In addition, since the column holding the rail is sandwiched between the floor and the ceiling of the facility, installation and removal thereof can be facilitated.

Further, according to the present embodiment, since the display device 16 is arranged in front of the monitoring camera device 10, appropriate information can be given to the customer without giving the customer a feeling of oppression. In addition, the surveillance camera 1
Since 0 can be noticed, it is possible to more reliably capture the face and the like of the customer. Further, according to the present embodiment, projections are provided before and after the curved road area, and this is detected by a sensor, and the speed thereof can be controlled. In addition, the movement sequence on the track, the stop of the monitoring camera device, the position of the camera, Can be controlled and zooming can be controlled, so that the inside of the area can be monitored as desired.

Further, according to the present embodiment, since the flat cable is provided in the cable storage case and power is supplied and signals are transmitted and received from the flat cable, the use of wireless communication is restricted. It is possible to use the surveillance camera device even in the area where the monitoring is performed.

Next, a description will be given of a second embodiment of the present invention. In this embodiment, surveillance camera device 10 includes an infrared sensor (not shown), and the movement sequence of surveillance camera device 10, the speed of the camera, and the stop
It is controlled by a signal from an infrared remote control device (remote controller). For example, the camera position change and zoom may be controlled from the infrared remote control. According to this embodiment, the number of signal lines of the flat cable can be reduced, and the size of the cable storage case can be reduced.

Next, a third embodiment of the present invention will be described. In this embodiment, a normal cable such as a SCSI cable is used without using a flat cable, and a cable take-up device is provided in a support of a cable storage case. The cable take-up device (so-called cord reel) is housed in a column of the cable storage case 72, which is arranged at a position substantially at the center of the extension distance of the rail. As shown in FIG. 10A, when the monitoring camera device 10 moves in a direction away from the column 1001 (for example, leftward in FIG. 10A), the cable winding device 1002
03 is extended, while the surveillance camera device 10 approaches the support (for example, FIG. 10).
When the cable moves to the right in (b), the cable operates to be accommodated in the winding device 1002.

According to this embodiment, since a relatively long cable can be used, the extension distance of the rail can be made longer. In addition, since the cable is pulled by the cable winding device 1002 toward the cable storage side with a certain amount of force, the cable storage case 7
The cable in 2 has some tension. Therefore, even when there are many curved roads in the track of the rail 20, it is possible to reduce the possibility that the cables become entangled.

Next, a fourth embodiment of the present invention will be described. FIG. 11A is a schematic front view illustrating the appearance of the monitoring camera device 100 according to the fourth embodiment.
The surveillance camera device 100 is different from the surveillance camera device 100 according to the first embodiment shown in FIG. Also, the monitoring camera device 100
Cable does not extend from the cable. In this embodiment, a battery is mounted inside surveillance camera device 100 so that it can travel on rail 20 by itself. The inside of the surveillance camera device 100 is substantially the same as that of the first embodiment shown in FIGS. 2 to 4, except that the circuit relating to the video signal to be displayed on the display device is eliminated in the integrated control unit. A transmission circuit for wirelessly transmitting a video signal captured by a camera is added, and a battery unit (not shown) is attached to the frame. As shown in FIG. 11B, behind the monitoring camera device 100, a terminal 122 for receiving a plug for charging a battery,
A cover 120 for protecting the terminals is provided.
In this embodiment, the transport mechanism and each unit are provided with a waterproof seal to prevent water from entering from outside, such as a parking lot or a fence surrounding a site. An infrared sensor 124 is arranged on the front side of the monitoring camera device 100, and its movement sequence, speed, stop, and the like can be controlled by a signal from an infrared remote controller (not shown).

Surveillance camera device 1 according to this embodiment
In No. 00, since the motor of the transport mechanism is driven by the battery, there is no need to supply power from a cable from outside. Therefore, the track of the rail 20 can be a closed curve. That is, it is possible to form a closed curve track (see FIG. 12A) around a fence surrounding a parking lot or a site. In FIG.
Reference numeral 6 denotes a battery station that supplies power to the monitoring camera device 100. Battery station 126
As in the first embodiment, a protrusion is formed on the side surface of the rail 20, and the sensor detects the protrusion, so that the monitoring camera device 100 can be stopped at a predetermined position. At the battery station 126, a suitable mechanism opens the cover 120 on the back of the surveillance camera device 100, inserts a power supply line with a plug at the tip into the terminal 122, and supplies power to the battery of the device 100. .

For example, during charging, the monitoring camera device 100
FIG. 12 (b) to prevent the operation of
As shown in FIG.
0, and a drop-in line (see reference numeral 130) to the battery station is made. Usually, two surveillance camera devices 100 are operated, and when one of the surveillance camera devices needs to be charged, the surveillance camera device 100 is operated. The device 100 may be moved to the service line (see reference numeral 132) to be charged, and the monitoring may be continued by at least one monitoring camera device 100 on at least the track of the rail 20.

According to the present embodiment, the surveillance camera device 100 is controlled by the rail 20
Self-propelled, it is possible to form a desired closed curve trajectory. In addition, it is possible to arrange a plurality of monitoring camera devices 100 on the track.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the appended claims, which are also included in the scope of the present invention. Needless to say, this is done. For example, a battery is mounted on the surveillance camera device according to the first to third embodiments, and a video signal of a video broadcast on a display device or a video signal captured by a camera is wirelessly transmitted. It is also possible to provide a communication circuit for transmitting and receiving, and to configure the surveillance camera device to run on the track of the rail 20 by itself. In the first embodiment, an infrared sensor is provided in the surveillance camera device, and various controls are performed by an infrared remote controller. However, the present invention is not limited to such a configuration, and wireless use is possible. In such a case, the wireless unit may be mounted on the monitoring camera device to perform various controls wirelessly.

In the fourth embodiment,
In the battery station, the battery unit is configured to be charged, but is not limited thereto.In the battery station, the battery unit itself is replaced with a charged one, and the removed battery unit is replaced with the station. May be configured to be charged. This eliminates the need to stop the monitoring camera device for a long time. Furthermore, in the above embodiment, the sensor is configured to detect the protrusion formed on the side wall of the rail. However, the present invention is not limited to this, and a contact-type sensor may be used. Alternatively, a curved path may be detected by using detection of something other than magnetism (for example, detection of light reflectance or the like).

In the first embodiment,
Using a column having a variable length as shown in FIG. 8, the column is fixed by pressing down the ceiling and the floor with supporting members at the upper and lower ends thereof, and the rail is held by an arm extending from the column. However, the present invention is not limited to this, and an arm may be attached to a wall surface and a rail may be held by the arm, or an L-shaped arm may be fixed to a ceiling and the arm May hold the rail. Further, in this specification, the function of one means / member is realized by two or more physical means / members, or the function of two or more means / members is realized by one physical means / member.
