Therefore, it can be realized with a simple transmission method and device configuration that eliminates the need for noise prevention processing and other processing. In particular, the transmission device portion of data such as images can be reduced in size and weight, and the spherical casing can be smoothly driven and rotated by driving from the lower surface side while maintaining the weight balance in the spherical casing.

  Since the horizontal azimuth detecting means is a magnetic azimuth sensor in which magnetoresistive elements for detecting geomagnetism are integrated, the horizontal azimuth detecting means can be configured at low cost and in a small size, and can stably control the change in the direction of imaging.

The power supply line does not need to be routed from the outside while being stably supported so that it can be placed and removed freely, and there is a high degree of freedom in the installation location. Without having to move safely and orderly places. At the same time, image data is transmitted by wire, and at that time, large-capacity transmission is possible by embedding a transmission line using a large-diameter vertical axis pin or the like and using the pin itself as a terminal. As in the case, the image signal can be stably acquired without being influenced by the external environment.

As a result, the imaging direction can be accurately controlled to be changed to the monitoring target. In particular, since the horizontal orientation detection means always maintains a horizontal state with respect to the geomagnetism regardless of the inclination of the casing around the vertical direction, the detection result based on the geomagnetism can always be obtained accurately, and the rotation control of the casing can be further controlled. It will be accurate and improve the practicality of control using detection means based on geomagnetism.

  The surveillance camera device 1 of the present embodiment includes a remote control unit 2 installed at a location separated from the device main body 1a shown in FIG. In the embodiment, the remote control unit 2 has a communication function, a storage unit, an input device, a data processing function, and the like, and is built in a computer connected to a display device. The operator can also control the drive by sending a control signal to the image pickup apparatus or its driving means to the apparatus main body side directly through the input device while watching the monitor screen. In the present embodiment, the apparatus main body 1a and the remote control unit 2 are connected, for example, wirelessly, and control signals and image signals are transmitted. The image signal is not limited to a computer device having a remote control unit, and may be transmitted to other arbitrary locations, remote locations, data centers, computers on a network, and the like. For example, in the present embodiment, a system such as a simple one-to-many multiplexable wireless RS485 is advantageously used, and control and image signals are transmitted and received between the apparatus main body 1a and the remote control unit wirelessly. Terminal control devices for these signals are mounted inside the base 10 of the apparatus main body 1a. As shown in FIG. 1, the base 10 is a support base that stably supports a casing 22 including an imaging unit 20 that is a camera body, and is provided in a box shape. Inside the base 10, a control unit 12 including a drive control unit 3 b that controls the rotation unit 30 is provided together with a control device 3 a that controls transmission and reception with the remote control unit 2.

  The rotating unit 30 is a rotation driving unit that rotates the casing 22 around a desired direction including the horizontal direction and the vertical direction to change the imaging direction of the imaging unit 20. In this embodiment, as shown in FIGS. 1 and 2, the rotation means 30 includes a vertical axis 35 that supports the rotation of the casing 22 in the horizontal direction, and a direction perpendicular to the direction of the vertical axis 35 ( And a horizontal shaft 33 that is set to be horizontal with respect to the ground and supports the vertical rotation of the casing 22. In the present embodiment, the rotation means 30 is fixed to a substantially central portion of the base 10 and is provided with a rotation support portion 36 having a vertical axis 35 therein, and is rotatably supported with respect to the vertical axis 35. The horizontal rotation part 34 and the vertical rotation part 32 connected and supported by the horizontal axis | shaft 33 arrange | positioned in the upper part vicinity are included. As shown in FIGS. 14 and 15, the casing 22 is attached to the upper end portion of the vertical rotation portion 32 of the rotation means 30. In response to a signal from the control means 12 of the base 10, the horizontal rotation unit 34 is rotated about the vertical axis 35 and the vertical rotation unit 32 is rotated about the horizontal axis 33, so that the casing 22 is perpendicular to the P direction around the horizontal direction. Rotate in a desired direction about the direction T. In FIG. 1, in the present embodiment, for example, a first drive motor 37 that rotates the horizontal rotation unit 34 and a second drive motor 38 that rotates the vertical rotation unit 32 are disposed inside the horizontal rotation unit 34. It is arrange | positioned and it is being fixed to the horizontal rotation part by the support means which is not shown in figure. The first and second drive motors 37 and 38 are connected to the vertical axis 35 or the horizontal axis 33 via a speed reducer, and are individually driven to rotate as drive sources. As the drive motor, an inexpensive saddle type motor or the like is advantageously applied.

  As shown in FIGS. 1 and 2, the imaging unit 20 includes, for example, a video camera including an imaging element such as a CCD that is an imaging unit, and a signal processor that processes the image signal, such as a lens of the camera. An optical system is provided on one end surface side in the longitudinal direction, and a main body portion is accommodated in a horizontally long box-shaped casing 22. In the present embodiment, the imaging direction R of the imaging unit 20 is set in the longitudinal direction of the casing 22, and the substantially central portion of the casing 22 in the longitudinal direction is fixed to the upper end portion of the vertical rotation unit 32. The imaging unit 20 is connected to the control unit 12 in a wired or wireless manner, changes its imaging direction as the casing 22 rotates in a required direction, and sends the captured image to the control unit 12 as an image signal. . The control unit 12 transmits the image data from the imaging unit 20 to the remote control unit 2 and detects the control data received from the remote control unit 2 and the horizontal direction detection unit (50) and the vertical direction detection unit (40). Based on this, the rotation means 30 is driven and controlled.

  In the present embodiment, as shown in FIG. 1, the horizontal direction detection means includes a magnetic direction sensor 50 and is attached to the casing 22 via a horizontal holding unit 60. The magnetic azimuth sensor 50 rotates with the casing 22 to detect a horizontal shift θ (see FIG. 15) with respect to the geomagnetism from the approximately south pole side to the approximately north pole side of the earth. The rotation angle of is detected. The magnetic direction sensor 50 is, for example, an integrated circuit in which a plurality of magnetoresistive elements form a bridge circuit in a horizontal plane, and in this embodiment, as shown in FIG. 5, two sets of bridges 152 and 154 and the bridges thereof A drive circuit 156, a bias drive circuit 160 that drives the bias coil 158, an output circuit 162 that outputs an output Vx in the X direction, and an output circuit 164 that outputs an output Vy in the Y direction are included. When the magnetic direction sensor 50 is rotated by θ with respect to the geomagnetism, the circuit outputs Vx in the X direction and Vy in the Y direction, and calculates and outputs the rotation angle θ from these output values. While such an integrated circuit magnetic orientation sensor 50 is inexpensive, it cannot perform normal detection in a state where it is affected by an external magnetic force other than geomagnetism, such as a drive motor. Therefore, in this embodiment, as described above, the horizontal direction detection means is used in a state where it is magnetically shielded. Furthermore, as shown in FIG. 6, a horizontal shift with respect to the geomagnetism can be accurately detected only when the magnetic direction sensor 50 is parallel to the geomagnetism and parallel to the ground. Therefore, in the present embodiment, the magnetic orientation sensor 50 is disposed outside the upper surface of the casing 22 at a position separated from the drive motor via a horizontal holding unit 60 described later, and the horizontal state of the magnetic orientation sensor is held. It has become.

  The horizontal holding unit 60 is a horizontal holding unit that holds the horizontal position of the magnetic direction sensor 50 with respect to the geomagnetism regardless of the inclination of the casing 22 around the vertical direction. As shown in FIGS. 3 and 4, the horizontal holding unit 60 has triangular plate-like support members 62 and 62 erected on the casing 22 at a predetermined interval, and has a round bar shape between the apexes thereof. The support bar 64 is attached so as to be substantially parallel to the upper surface of the casing 22. Further, swing members 66, 66 formed by bending the substantially central portion along the curved surface of the support rod 64 are suspended at a predetermined interval, and the magnetic direction sensor 50 is suspended at the lower end thereof. A horizontal base 68 on which is installed is connected so as to be able to swing freely. Each part 62-68 of these horizontal holding | maintenance parts 60 is formed with the raw material which can interrupt | block the influence of external magnetic forces, such as each made of wood or resin. The horizontal holding unit 60 holds the horizontal position on the casing 22 while properly blocking external magnetic force from a magnetic source such as a drive motor other than geomagnetism by using each component member as a blocking member, so that the orientation based on geomagnetism can be accurately determined. Can be detected. Accordingly, a monitoring camera device that can accurately detect the rotation angle of the casing 22 around the horizontal direction using an inexpensive magnetic direction sensor 50 can be manufactured with a simple configuration at low cost. The output of the magnetic orientation sensor 50 is supplied to the control means 12 of the base 10 and used for controlling the rotation means.

  In the present embodiment, the vertical direction detection means includes the acceleration sensor 40, and is around the vertical axis of the casing 22, that is, the imaging direction (for example, the horizontal axis around the horizontal axis (virtual horizontal axis) such as the horizontal axis 33). The inclination position of the sector movement) is detected. The acceleration sensor 40 is fixed inside the casing 22. As the acceleration sensor 40, for example, an integrated circuit in which a plurality of piezoresistive elements form a bridge circuit in a vertical plane is advantageously applied, and a signal due to a resistance difference that appears due to a strain due to acceleration in each direction is used. Outputs the displacement from the reference position. The acceleration sensor 40 using such an integrated circuit is inexpensive, and the surveillance camera device can be configured simply and inexpensively. The output of the acceleration sensor 40 is supplied as needed to the control means 12 of the base 10 and is used for direction change control of the imaging direction. The acceleration sensor 40 may be a position where the vertical rotation angle around the horizontal axis of the casing can be detected. For example, the acceleration sensor 40 may be attached to a desired position of the vertical rotation unit 32 that rotates together with the casing.

  On the other hand, a surveillance camera system to which the surveillance camera device 1 of the present embodiment is applied will be described. As shown in FIG. 8, for example, a plurality of surveillance camera device bodies 1a, 1a,. . . Is applied to a line monitoring system in which a plurality of production lines 6 are prepared at positions overlooking the lines for each predetermined range. The production line 6 is provided with a signal generator for sending a detection signal including the position number to the remote control unit 2 when a failure such as a failure or a defect is detected at a predetermined location. The remote control unit 2 is connected to the apparatus main bodies 1a, 1a,. . . Control data for controlling the rotation means 30 is sent to the drive control unit 3b of the control means, and image signals are transmitted and received wirelessly from the control device 3a of the control means of each surveillance camera device body 1a. Control data representing the position of each production line 6 and the direction from the corresponding monitoring camera device main body 1a is stored in the control database 4 in advance.

  With the above configuration, the operation of the monitoring camera device 1 according to the present embodiment will be described together with the monitoring camera system. First, when a defect location occurs on the production line 6, a failure detection signal is supplied from the location to the remote control unit 2. Upon receiving the detection signal, the remote control unit 2 searches the control database 4 for the position where the signal is generated and the imaging direction of the camera. Next, the remote control unit 2 monitors the monitoring camera device main bodies 1a, 1a,. . . Control data representing the position and imaging direction is generated and transmitted. For example, as shown in FIG. 9, the control data includes a header (“JCa01”) indicating a camera position starting with J, horizontal orientation data (“315”) represented by 360 degrees, and vertical orientation data (“335”). ).

  Next, each surveillance camera device main body 1a, 1a,. . . As shown in FIG. 10, the control means 12 determines whether or not the header starting with J is that of its own device in step S10. If it is the data of its own device, the control means 12 of the monitoring camera device proceeds to step S12, and detects horizontal azimuth data of 3 characters from the sixth digit. The detected horizontal azimuth data is numerically converted as control data for the rotating means of the own apparatus in step S14. Similarly, as shown in FIG. 11, it is determined in step S16 whether or not it is the device itself. In step S18, three-character vertical azimuth data from the ninth digit is detected, and numerical conversion is performed in step S20.

  Next, the control means 12 of each monitoring camera device 1 controls the imaging direction to the object based on the numerically converted data. First, in the driving around the horizontal direction of the casing, as shown in FIG. 12, it is determined whether or not control data is input from the remote control unit 2 in step S22. Then, based on the horizontal azimuth data from Steps S10 to S14, the reference data for the horizontal rotation shift with respect to the geomagnetism of the casing is generated. Next, the process proceeds to step S <b> 26, and the measurement of the horizontal shift of the current casing 22 with respect to the geomagnetism is started based on the data from the magnetic direction sensor 50. In the measurement by the magnetic azimuth sensor, for example, when the casing is currently oriented at an angle θ with respect to the geomagnetism (see FIG. 15), as shown in FIG. The direction is read, and then the measured values Vx and Vy from the magnetic direction sensor 50 are output to the control means in step S52. Next, in step S54, the Vx and Vy outputs are A / D converted, and in step S56, the current rotational shift with respect to geomagnetism is calculated based on the converted value. Next, the horizontal azimuth calculation result is output in step S58 and used in step S28 (FIG. 12). In this measurement, the magnetic azimuth sensor 50 needs to hold the horizontal when detecting the horizontal angle θ. In the present embodiment, the magnetic azimuth sensor 50 is provided on the horizontal base 68 of the horizontal holding unit 60, and the casing 22 is inclined at an arbitrary angle around the vertical direction around the horizontal axis as shown in FIG. Even in that case, the horizontal state is maintained. That is, in the horizontal holding unit 60, the swinging member 66 can swing on the support rod 64 supported by the support members 62 and 62 with respect to the movement of the casing 22 around the vertical direction. The attached horizontal base 68 maintains the horizontal state of the magnetic orientation sensor regardless of the vertical inclination of the casing. Thereby, the horizontal rotation angle of the casing 22 with respect to geomagnetism can be detected accurately.

  Returning to FIG. 12, next, in Steps S28 and S30, the data on the rotational position of the casing 22 around the horizontal direction output in Step S58 is compared with the target reference data, and they match. It is determined whether or not. If not coincident, in step S32, the horizontal rotation unit 34 is driven to rotate the casing in the horizontal direction. Then, the process returns to step S26 again, the current horizontal orientation is measured, and steps S26 to S32 are repeated until it matches the target reference data in steps S28 and S30. When the target position is reached in step S30, the horizontal drive is stopped in step S34.

  Subsequently, the driving of the casing 22 around the vertical direction is similar to the driving around the horizontal direction, as shown in FIG. Then, the process proceeds to step S38, and the above-described steps S16 to S20 shown in FIG. 11 are performed, and reference data for the vertical inclination of the casing is generated. Next, the process proceeds to step S40, and the measurement of the current position of the angle around the horizontal axis is started based on the data from the acceleration sensor 40. For example, when the casing as shown in FIG. 14 is tilted backward about the horizontal axis, the measurement of the acceleration sensor 40 is read by the acceleration sensor 40 in step S60, and then in step S62, as shown in FIG. The measurement value from the acceleration sensor 40 is output to the control means 12. Next, in step S64, the output value is subjected to pulse conversion, and the result is output as vertical orientation data in step S66. The output vertical orientation data is used in step S42 shown in FIG. Returning to FIG. 13, in steps S42 and S44, the data on the rotational position of the casing around the vertical direction output in step S66 and the target vertical reference data are compared and matched. Determine whether. If not, in step S46, the vertical rotation unit 32 is driven to swing up and down (tilt), that is, rotate around the horizontal axis of the casing in the vertical direction (sector-shaped rotation operation). Then, the process returns to step S40 again, the current vertical orientation is measured, and steps S40 to S46 are repeated until it matches the target reference data in steps S42 and S44. When the target position is reached in step S44, the vertical drive is stopped in step S48.

  As described above, the desired monitoring camera device 1 changes the posture of the casing 22 and directs its imaging direction to the defective portion of the production line 6. That is, as shown in FIG. 14, the casing 22 rotates in the direction of the arrow P that rotates around the horizontal direction by the rotation of the horizontal rotation unit 34, and freely rotates in the direction of the arrow T by the rotation of the vertical rotation unit 32. To do. As described above, the rotation of the casing detects the current casing direction based on the detection results of the magnetic direction sensor 50 which is a horizontal direction detection unit and the acceleration sensor 40 which is a vertical direction detection unit. Since the control data including the direction of the monitoring target is compared and controlled, the configuration of the casing drive source can be easily and accurately controlled with a simple and inexpensive motor configuration, and the monitoring camera has a simple and inexpensive configuration. The device can be manufactured. In the monitoring camera device 1 facing in a desired direction, the object is photographed by the imaging unit 20, and an image signal represented by the result is sent to the control means 12. Upon receiving the image signal, the control means 12 converts this into data that can be wirelessly transmitted and transmits it to the remote control unit 2. The remote control unit 2 records or demodulates the image signal from the surveillance camera device 1 and returns it to the original image signal and displays it on a monitor or the like, and accurately confirms the site where the defect of the production line 6 has occurred at a remote location. be able to.

  As described above, according to the surveillance camera device of the present embodiment, the casing 22 of the substantially box-shaped imaging unit 20 can be horizontally and vertically rotated by the rotating means 30 to change the horizontal direction thereof. Since the magnetic direction sensor 50 detects the geomagnetism as a reference, and the vertical direction change is detected by the acceleration sensor 40 and is directed to a desired direction based on those results, a wide range of monitoring can be performed and stable. Position control can be performed. Further, in the present embodiment, the magnetic azimuth sensor 50 always maintains the level by the horizontal holding unit 60 and detects the horizontal shift θ with respect to the geomagnetism, so that the detection can be made stable. Therefore, the imaging direction can be stably controlled by an inexpensive motor and element, and an inexpensive apparatus can be provided. In this embodiment, a plurality of surveillance camera apparatus main bodies 1a, 1a,. . . The apparatus main body 1a receives control data representing the imaging direction, transmits the imaging result from the imaging unit 20 to the remote control unit 2, and further receives a command from the remote control unit 2 and rotates. Since the control means 12 including the drive control unit 3b for driving and controlling 30 is provided, desired objects in a wide range can be reliably monitored remotely by remote operation. Therefore, it is possible to reduce the number of monitoring personnel, reduce the implementation cost of the monitoring camera system, improve the convenience of remote monitoring, and the like.

  Next, a second embodiment of the surveillance camera device according to the present invention will be described with reference to FIGS. 18 to 24.

Yes. Between the support members 316 and 316, the imaging unit 20 is fixed rotatably by screws 318 and 318 so that the imaging direction faces the substantially center of the front sphere 220a.

  The imaging unit 20 includes, for example, an imaging device such as a CCD and a signal processor that processes the image signal, and these are mounted in a cylindrical case provided with an optical system such as a lens and integrated with the casing 220. Rotate. The image signal from the imaging unit 20 is supplied to a transmission processing unit 80 that is wirelessly controlled. The transmission processing unit 80 is a transmission unit that wirelessly transmits the image data captured by the imaging unit 20 to the control unit 12 on the support unit 70 side, and at most about 30 cm to 1 m with the support unit 70 that supports the casing 220 at the bottom. A weak radio for a specific low-power station that transmits data between a certain distance is used.

  The acceleration sensor 40 is attached to a substantially central portion of the bottom plate member 314 of the mounting base 312. A two-dimensional or three-dimensional sensor is advantageously applied to the acceleration sensor 40 of the present embodiment, and mainly detects a rotational shift around the vertical direction among movements rotated in all directions of the casing 220. As in the first embodiment, the magnetic orientation sensor 50 is arranged in the imaging unit 20 via the horizontal holding unit 60 to which the circuit shown in FIG. 4 in which a plurality of magnetoresistive elements are integrated is applied. Also in the present embodiment, while maintaining the horizontal position with respect to the geomagnetism, the rotational shift around the horizontal direction with respect to the geomagnetism is detected among the omnidirectional driving of the casing 220. The detection results of the acceleration sensor 40 and the magnetic azimuth sensor 50 are wirelessly transmitted to the control unit 12 via the transmission processing unit 80 in the same manner as the image signal from the imaging unit 20.

  As shown in FIG. 18, the casing 220 is placed on the support means 70 so as to be freely detachable, that is, simply placed. The support means 70 is a support means for placing and supporting the casing 220 on the upper surface side of the casing 220 so as to be detachable. In the present embodiment, the support means 70 is located immediately below the spherical casing 220 and supports the casing. A receiving frame structure 300 and a support base portion 400 that supports the receiving frame structure 300 are included. In the present embodiment, the support base portion 400 has a large-diameter disk member 400a attached with a small cylindrical member 400b having a small diameter at the approximate center thereof, and further a bottom portion of the receiving frame structure 300 attached thereto. The receiving frame structure 300 is a means for placing and supporting the casing 220 on the upper surface side of the casing 220 while allowing the casing 220 to rotate. In the present embodiment, the frame mechanism attached to the upper portion of the support base 400 and the frame Stable support means attached to and supported by the mechanism. Specifically, the frame mechanism is formed and provided so that the X-axis member 300a and the Y-axis member 300b made of a solid curved frame member curved along the bottom surface of the casing 220 intersect each other.

  The stable support means detachably supports the casing 220 on top of the X-axis member 300a and the Y-axis member 300b, and always stably supports the casing 220 while allowing the angle of the casing 220 to be freely changed. In this embodiment, as shown in FIG. 22, the stable support means includes, for example, four ball casters including, for example, a freely rolling rolling member in each of the X-axis member 300a and the Y-axis member 300b of the frame mechanism. 706 is distributed and arranged on each shaft member (in the present embodiment, at a plane equidistant position from the center). The balls of the ball caster 706 are arranged at positions projecting slightly upward from the upper surfaces of the X-axis member 300a and the Y-axis member 300b. Therefore, when the casing 220 is placed on the upper surface, the X-axis members 300a and Y-axis The casing 220 is supported in a four-point support state slightly lifted from the upper end surface of the member 300b. These ball casters 706 may be supported at three points, or supported at a plurality of five or more points while being placed on the balls at the same time. The stable support means further supports the casing 220 on the support means so that the casing 220 can rotate smoothly when a force is applied to the casing in an arbitrary rotation direction while the casing 220 is detachably supported. Place and support. The support means 70 may be a simple base instead of the frame, and a free rolling mechanism may be provided thereon to support the bottom curved surface portion of the casing 220 so that it can be placed, detached, and freely rolled. Further, without providing the ball caster of this embodiment, the upper end portion of the U-shaped cross section of the X-axis and Y-axis members is coated with Teflon (registered trademark), or a low friction member such as felt cloth is attached to the casing. You may make it implement | achieve mounting, detachable, and a free rolling structure.

  Furthermore, in this embodiment, the rotation means 30 provided in the receiving frame structure 300 includes a drive motor and a drive roller driven by the drive motor, and these constitute the drive mechanism 500. The drive mechanism 500 is driven in response to a signal from the control means 12 with the casing 220 placed on the receiving frame structure 300 and detachably supported, and rotates a roller as a rolling element that comes into contact with the curved surface of the casing. The imaging direction of the imaging unit 20 is forcibly changed by moving. In FIG. 20, the drive mechanism 500 which is the rotation means 30 in this embodiment includes a vertical drive mechanism 500a that rotates the casing 220 along a vertical plane, and a horizontal drive mechanism that rotates the casing along a horizontal plane. 500b, and the spherical casing 220 is driven to rotate in all directions.

  In the present embodiment, the drive mechanism 500 includes drive rollers 522, 524, 526, 528 and drive motors 620, 640, 660, 680. The driving rollers 522 to 528 are contact members that rotate while contacting the lower surface of the casing or in the vicinity of the lower surface, and rotate the casing made of the spherical body in an arbitrary direction by a frictional force. These roller shafts are connected to the rotation shafts of drive motors 620 to 680, respectively, and are driven to rotate. 20 and 21, in this embodiment, the driving rollers 522 to 528 are provided so as to be in contact with and separated from the bottom curved surface of the casing 220 by a contact / separation mechanism described later. In the present embodiment, these drive rollers are made of friction members, and more specifically, are constituted by first to fourth rollers 522, 524, 526, and 528 formed of friction members such as rubber. Each of the rollers 522 to 528 is formed to be able to rotate in close contact with the casing 220, and is attached to the rotation shaft of each of the drive motors 620 to 680 so as to be rotatable in both directions to constitute a friction rolling mechanism. Each roller is in contact with the cylindrical surface and the spherical surface, but by forming the roller from rubber or the like having a large surface friction coefficient, the spherical surface is reliably captured and driven. In this embodiment, in FIG. 20, the first and second drive rollers 522 and 524 and their motors 620 and 640 installed facing the upper end portions on both ends of the X-axis member 300a bring the casing 220 into a vertical plane. The third and fourth drive rollers 526, 528 installed opposite to the vicinity of the upper ends of both ends of the Y-axis member 300b provided orthogonal to the X-axis member 300a. The motors 660 and 680 serve as a horizontal drive mechanism that rotates the casing 220 along a horizontal plane. In other words, the rollers of the vertical rotation mechanism or the horizontal rotation mechanism are arranged at separation positions (linear positions) in the diameter direction. The casing 220 is driven to rotate in all directions by driving the vertical driving means and the horizontal driving means alone or in combination. For example, when the first and second rollers 522 and 524 are brought into close contact with the casing 220 and are both driven to rotate forward, the casing 220 rotates, for example, upward around the vertical direction. When the rollers 522 and 524 are both rotated in the reverse direction, the casing 220 rotates downward. Further, when the third and fourth rollers 526 and 528 are brought into close contact with the casing 220, the third roller 526 is rotated forward, and the fourth roller 528 is rotated reversely, the casing 220 rotates counterclockwise in the horizontal plane, When the third roller 526 is rotated backward and the fourth roller 528 is rotated forward, the third roller 526 rotates rightward.

  In the present embodiment, the first and second cam members 714 and 715 are made of an elliptical plate having a major axis and a minor axis, and are driven to rotate independently through first and second drive actuators 716 and 717, respectively. . Each of the first and second cam members is set such that the plate thickness surface is always in contact with the contact surface of the contact member 712 urged by the urging spring 723, for example. The corresponding roller groups (522, 524), (526, 528) are driven against the casing in a freely releasable manner by rotating the first and second ellipsoidal plates by 90 degrees each time via the arm member. . In this embodiment, when the lower first cam member 714 is rotated, the rollers (522, 524) of the vertical driving means simultaneously contact or separate from the casing, and the horizontal cam means is rotated by the rotation of the second cam member 715. Each of the rollers (526, 528) simultaneously contacts or separates from the casing. Each roller is driven by motors 620 to 680, and is controlled to be driven and stopped at each timing of contact and separation of the rollers with respect to the casing.

  On the other hand, the motors 620 to 680 and the first and second drive actuators 716 and 717 of the drive mechanism 500 are connected to the control means 12 provided inside the support base 400 and are connected to the remote control unit 2. In response to a wireless control signal, the motors 620 to 680 and the first and second drive actuators 716 and 717 of these drive mechanisms are driven via the drive control unit 3b of the control device. As described above, the transmission / reception control unit 3a and the drive control unit 3b of the control unit 12 control the drive of the drive mechanism, and are provided on the receiving frame structure 300 side of the surveillance camera body 1a. In response to the monitoring image data and the detection results of the acceleration sensor 40 and the magnetic direction sensor 50, the image data is transmitted to and received from the remote control unit 2 via radio. The transmission / reception control unit 3a and the drive control unit 3b of the control unit 12 are incorporated in the transmission / reception of image data and control data and the image / data transmission unit 450 for controlling them. In the present embodiment, these signals are: It is converted into a signal for wireless transmission and transmitted wirelessly. At this time, the motors 620 to 680, the first and second drive actuators 716 and 717, or the control signal for notifying the operation status of the monitoring camera may be sent to the remote control unit 2 side as necessary. Further, data may be exchanged between the image / data transmission unit 450 and the remote control unit 2 by wire. In the present embodiment, data transmission is performed wirelessly as described above. For example, a spread spectrum wireless transceiver is advantageously applied to exchange image signals and control signals with the remote control unit 2. do.

  In the configuration as described above, the operation when the surveillance camera device 1a of the present embodiment is installed and applied to the production line 6 as shown in FIG. 8 will be described. In this case, first, the support base 400 is installed at a predetermined location to be monitored, and the casing 220 in which the imaging unit 20 is stored is placed thereon. Next, when the imaging unit 20 is turned on by an operation from the remote control unit 2, an image signal representing the monitoring image taken by the imaging unit 20 is transmitted from the transmission processing unit 80 to the image of the support unit 70 in the weak wireless band. The image / data transmission unit 450 transmits the data to the remote control unit 2 wirelessly, and a monitor image in the current imaging direction is displayed on the monitor of the remote control unit. Similarly to the above-described embodiment, when the remote control unit 2 receives the failure signal of the production line 6, the remote control unit 2 searches the control database 4 for data corresponding to the failure signal. For example, the remote control unit 2 monitors the control data as shown in FIG. Send to device. Upon receiving the control data, the control device 12 of the surveillance camera device generates horizontal azimuth and vertical azimuth data for rotating the casing, that is, the imaging direction, through steps S10 to S20 shown in FIGS. First, when the casing is rotated around the horizontal direction, the steps S22 to S34 shown in FIG. 12 and the steps S50 to S58 shown in FIG. . At this time, the specific drive operation of the casing is performed as shown in FIGS. 21-1 and 21-2. That is, based on the control data from the remote control unit 2 and the detection result from the magnetic direction sensor 50, the control device 12 determines that the second cam member 715 is in an oblong elliptical state via the upper second drive actuator 717, for example. In step 23, the long axis is rotated 90 degrees so as to be in a vertically long elliptical state with the long axis in the vertical direction. Thereby, the long-axis side plate thickness surface of the second cam member 715 spreads the contact member 712, compresses the spring (723), laterally moves the pin member 720a outward, and moves the roller through the arm members 700a to 700d. 526 and 528 are brought into contact with the surface of the casing 220. At this time, for example, the first cam member 714 is also held in a vertically long elliptical state, the platen surface on the short axis side hits the contact member 712b, and the rollers 522 and 524 are separated from the surface of the casing by the action of the spring. In this state, the third and fourth motors 660 and 680 are driven to rotate the rollers 526 and 528 to rotate the casing 220 around the horizontal direction. For example, when the casing is rotated leftward by comparing the control data from the remote control unit and the detection result from the magnetic direction sensor 50, the third roller 526 is rotated forward and the fourth roller 528 is reversed. Rotate. Similarly, when rotating rightward, the third roller 526 is reversely rotated and the fourth roller 528 is rotated forward.

  Subsequently, when the casing is rotated around the vertical direction, the steps S36 to S48 shown in FIG. 13 and the steps S60 to S66 shown in FIG. Let The driving operation of the casing at this time is opposite to the rotation in the horizontal direction, for example, only the first cam member 714 spreads the spring and the rollers 524 and 526 are brought into contact with the surface of the casing to cause the rollers 526 and 528 to move, for example. Let it be in a free state. Then, both the rollers 522 and 524 are rotated forward or reverse to rotate the casing 220 around the vertical direction.

  In this way, at least one of the vertical drive and horizontal drive rollers abuts near the bottom of the casing via the rotary solenoid by the control signal from the remote control unit 2, and the surveillance camera is imaged by rotating the casing in the corresponding direction. Change direction to the target object. In the drive mechanism of this embodiment, the operation on the control or remote control unit side can be simplified by combining simultaneous contact and separation of the drive rollers with respect to the casing. In the monitoring camera device main body 1a facing in a desired direction, the object is photographed by the imaging unit 20, and an image signal is sent to the control means 12 via the transmission processing unit 80. Upon receiving the image signal, the control means 12 converts this into data that can be wirelessly transmitted and transmits it to the remote control unit 2, and a monitor image in the current imaging direction is displayed on the monitor of the remote control unit. Therefore, also in the present embodiment, it is possible to accurately confirm the site where the defect of the production line 6 has occurred in a remote place, and it is possible to execute extremely effective remote monitoring. The surveillance camera device itself can be manufactured with a simple configuration and low cost. In addition, a reduction in size and weight can be realized. In order to change the imaging direction of the surveillance camera, it is only necessary to drive a casing mounted in a detachable camera in response to a control instruction signal from the remote control unit, and the casing and the receiving frame structure are separated. It can be transported and managed, and the installation and adjustment of the equipment is extremely simple. In addition, the repair and maintenance of the device are extremely easy to perform and the convenience in use can be improved.

  In the embodiment described above, the monitoring camera device is a stationary type, but the monitoring camera device itself may be configured to self-run. For example, it is provided with position detection means for detecting the position of the surveillance camera device itself, and moves to, for example, the vicinity of the failure position of the machine according to an instruction from a remote control unit etc. The imaging direction may be changed by arbitrarily rotating around the vertical direction. Further, at this time, it is possible to effectively use such as changing the position of the apparatus and the imaging direction while using in combination with the detection result of the magnetic direction sensor or the acceleration sensor. The remote control unit includes a similar wireless transceiver that transmits and receives a wireless signal from the control device, and a display unit that demodulates the signal and displays the signal on a monitor or the like. It is also possible to change the direction of the drive mechanism and the casing-surveillance camera by operating the operation lever while viewing the captured image of the camera. From the remote control unit side, it is possible to quickly and accurately image a target object by instructing an operation while visually grasping it from the monitor screen of the remote control unit. Further, it is preferable to provide a control function for controlling one or a plurality of surveillance cameras with one remote control unit.
