Description

  The present invention relates to a remote monitoring device, and more particularly to a remote monitoring device suitable for application to, for example, a surveillance camera system.

  For example, in a surveillance camera system, an image signal obtained from a video camera installed at a predetermined location to be monitored is sent to a location away from the location, and an image represented by the image signal is monitored by a display or the like, or Image signals are recorded on a video tape or the like and monitored remotely. Conventionally, in a remote monitoring device such as a surveillance camera system, for example, a part where a surveillance part such as a camera can be rotated or moved in order to widen the surveillance range in a place where a video camera is installed has been proposed. (See Patent Document 1 or Patent Document 2).

  For example, in Patent Document 1, a rail is laid in an area to be monitored, and a casing to which a camera unit is attached is run along the rail. In this case, transmission of the video signal to the display has been performed by a cable.

  In Patent Document 2, a camera is attached to a turntable, and the video signal is subjected to image processing by an image processor, and the turntable and the camera are controlled so as to track an intruder or the like.

Further, in this case, since the cable is included, a mechanism for inserting and removing the cable when the camera unit is traveling is required. For this reason, the apparatus became expensive and the installation location was limited. On the other hand, in Patent Document 2, since the details of the mechanism of the turntable are not clear because it is explained by a block diagram, in general, for example, a box-type camera has a shaft that supports the position of its center of gravity attached to the turntable. As a result, the rotating shaft was rotated horizontally by a combination of many rotating gears. Further, when vertical rotation is required, a mechanism for rotating in the vertical direction about the center of gravity axis is further required. For this reason, there was a problem that the number of parts increased and it became expensive. Furthermore, many burdens are applied to the fulcrum shaft, and there is a problem that it is necessary to devise maintenance and smooth rotation.

In other words, in the present embodiment, the rollers for vertical rotation or horizontal rotation are arranged on a cross line passing through the center of the bottom of the casing to be placed. The arm member 100 is bent in a square shape, and an intermediate position thereof is pivotally supported by the support shaft 104 on the X-axis or Y-axis members 30a and 30b. The arm member 100 is arranged on the X-axis member and the Y-axis member so that the upper part is expanded upward, and the lower end side is horizontally expanded or retracted via the support shaft 104. Each pair of rollers (522, 524) and (526, 528) is brought into contact with and separated from the casing surface. One end is engaged with a long groove 118 formed on the lower end side of each arm member 100a, 100b, and a rod-shaped pin member 120 extends laterally toward the inner central portion of the arm member.

Then, an urging member 123 made of a pressing spring is inserted between the support frame 122 and the contact member 112, and thereby the pin member 120 is always urged in the direction of extension of the free end thereof. The rollers 522 to 528 are urged so as to be always separated from the casing surface. As shown in FIG. 6, each pin member 120 and the contact member 112 fixed to them are arranged in a cross shape, and the free end side of each pin member is closely opposed at the center position of the bottom of the casing to be placed.

Further, in FIG. 6, a cross block 124 is provided on the base 40 side by a supporting means (not shown) at a position corresponding to the arrangement portion on the free end side of each pin member at the center position of the bottom of the casing. Yes. The free ends of the pin members 120 are inserted into the cross-shaped guide holes 126 of the cross block 124 so as to be movable forward and backward. Furthermore, in the present embodiment, the first and second drive actuators 116 and 117 are each composed of a rotary solenoid that is spaced down and up so as to sandwich the cross block 124 therebetween. The first and second cam members 114 and 115 are arranged to face each other up and down through the boss 128 and face up and down, and these cam members are connected and supported.

  In the present embodiment, the first and second cam members 114 and 115 are made of an elliptical plate having a major axis and a minor axis, and are individually rotationally driven via first and second drive actuators 116 and 117, respectively. . Each of the first and second elliptical plates is always in contact with the contact surface of the contact member 112 urged by the urging spring 123, for example, so that the first and second elliptical plates are in contact with each other. The corresponding driving roller is driven against the casing by being rotated by 90 degrees, and is driven so as to be separated. In the present embodiment, when the lower first cam member 114 is rotated, the vertical rotation driving rollers simultaneously contact or separate from the casing, and the rotation of the second cam member 115 causes the horizontal driving rollers to move from the motors 62. It is driven by 68 and controlled to be driven and stopped at each timing of contact and separation states of the rollers with respect to the casing.

  On the other hand, the motors 62 to 68 of the drive mechanism 50 and the first and second drive actuators 116 and 117 are connected to a radio transceiver 45 with a radio controller provided in the base 40, and this embodiment. Then, upon receiving a wireless control signal from the remote control unit 90, the motors 62 to 68 and the first and second drive actuators 116 and 117 of these drive mechanisms are driven via the control device. The wireless transmitter / receiver 45 is provided on the receiving means 30 side and receives data such as monitoring images from the monitoring camera 10, and further transmits and receives data such as images and the like to / from the remote control unit 90 via a control device. The control means 11, and at this time, the drive motors 62 to 68, the first and second drive actuators 116 and 117, the control signal for notifying the operation status of the monitoring camera, and the like are sent to the remote operation unit 90 side as necessary. . Note that data may be exchanged between the wireless transceiver 45 and the remote control unit 90 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 90. do. In the present embodiment, the remote control unit 90 includes a similar wireless transmitter / receiver that transmits / receives a wireless signal from the wireless transmitter / receiver 45, a display unit that demodulates the signal and displays it on a monitor, and an operation lever. It is advantageous to provide a control function for controlling a plurality of surveillance cameras with one remote control unit. The instructor turns the drive mechanism and the casing-surveillance camera by operating the operation lever while viewing the captured image of the surveillance camera via the monitor.

  In the configuration as described above, first, the base 40 on which the receiving means 30 is fixed is installed at a predetermined location to be monitored, and the casing 20 in which the monitoring camera 10 is housed is placed thereon. Next, when the monitoring camera 10 is turned on by an operation from the remote control unit 90, an image signal representing the monitoring image taken by the monitoring camera 10 is transmitted to the wireless transceiver 45 side of the receiving means 30 in a weak wireless band. Further, the wireless transmitter / receiver 45 wirelessly transmits the data to the remote operation unit 90, and a monitoring image in the current monitoring direction is displayed on the monitor of the remote operation unit. When viewing the monitoring image and changing the monitoring direction, for example, when changing the monitoring direction in the vertical direction in FIG. 4A, the first and second rollers 522 and 524 of the X-axis member 30a are rotated. In the plan view shown in FIG. 4A, when the upward rotation in the drawing is a positive rotation, an instruction to rotate the first and second rollers 522 and 524 in the positive rotation direction is performed wirelessly by operating the lever of the remote control unit. To the second transmission means side of the receiving means 30. As a result, the control device of the wireless transceiver that has received the wireless instruction drives the first and second drive actuators to bring the rollers 522 and 524 into close contact with the casing 20 and drives the motors 62 and 64 of the drive mechanism to rotate forward. Then, the first and second rollers 522 and 524 rotate forward and the casing 20 rotates upward. On the contrary, when the motors 62 and 64 are rotated in the reverse direction, the casing 20 is rotated downward. As a result, the monitoring direction of the monitoring camera 10 moves up and down, an image signal representing the monitoring image is wirelessly sent to the second transmission means 11, and further, those data are transmitted to the remote control unit 90.

  Next, when changing the monitoring direction to the left and right, an instruction to rotate the third and fourth rollers 526 and 528 is transmitted from the remote control unit side to the second transmission means of the receiving member, that is, the wireless transceiver 45. For example, when rotating in the left direction, the third roller 526 is rotated forward and the fourth roller 528 is rotated backward. In this case, the first and second rollers 522 and 524 are retracted by the drive actuator of the rotary cam drive mechanism 102, and the third and fourth rollers 526 and 528 are rotated in close contact with the casing 20. Similarly, when rotating in the right direction, with the first and second rollers 522 and 524 retracted, the third roller 526 is brought into close contact with the casing 20 and rotated in the reverse direction, and the fourth roller 528 is brought into close contact. When the rotation is normal, the casing 20 rotates leftward in the horizontal plane. The monitoring image is transmitted to the remote control unit 90 via the wireless transceiver 45 as described above.

  Next, the detailed operation of the contact / separation control unit 56 will be described. When the first cam member 114 receives a control signal from the remote control unit via the first drive actuator 116 at the lower part, 6, the long axis side plate thickness surface of the first cam member 114 spreads the contact member 112 and compresses the spring (123) to rotate the pin. The member 120 a is laterally moved outward, and the driving rollers 522 and 524 are brought into contact with the surface of the casing 20 through the arm member 100. At this time, for example, the second cam member 115 is also held in an oblong elliptical state, and the platen surface on the short axis side hits the contact member 112b, and the driving rollers 526 and 528 are separated from the surface of the casing by the action of the spring. When the first and second drive motors 62 and 64 are driven in this state, the rollers 522 and 524 rotate in the same direction as in FIG. 4A and the casing 20 rotates along the vertical plane to Change the monitoring direction of the surveillance camera. In the case of rotation in the horizontal plane, in contrast to the above, for example, only the second cam member 115 pushes and spreads the spring, and the driving rollers 526 and 528 are brought into contact with the surface of the casing to make the rollers 522 and 524 free, for example. In this state, the casing is horizontally rotated. As a result, at least a vertical or horizontal driving roller is brought into contact with the vicinity of the bottom of the casing via a rotary solenoid by a control signal from the remote control unit 90, and the monitoring direction of the monitoring camera is changed by rotating the casing in the corresponding direction. Turn around. In the driving mechanism of this embodiment, the driving roller 522-528 causes the casing, that is, the monitoring camera to rotate along the vertical plane and the horizontal plane, thereby remotely operating the vertical and horizontal intersection positions. An operation instruction is given from the remote operation unit while being visually identified by the lever operation of the unit. In the present embodiment, the control or the operation on the remote control unit side can be simplified by combining simultaneous contact with the casing of each drive roller, simultaneous separation, and the like.

  As described above, according to the remote monitoring apparatus of the present embodiment, the spherical casing 20 houses the monitoring camera 10 and the transmission processing unit 8 that wirelessly transmits an image signal representing the monitoring image therein, and the casing. The casing 20 is rotatably mounted in a receiving state by receiving the curved surface at the bottom of the base 20 by the receiving means 30, and the monitoring direction of the surveillance camera is changed by rotating the casing 20 along the curved surface of the receiving means 30. Since the drive mechanism 50 is provided, the receiving means is provided with transmission / reception / control means for transmitting data such as images from the surveillance camera to the remote operation unit and driving the drive mechanism upon receiving a wireless control signal from the remote operation unit. Data transmission between the surveillance camera and the second transmission means on the receiving means side can be easily used and can be performed at a short distance using weak radio waves capable of transmitting a large amount of data such as images. In this case, since the transmission distance is short, a simple transmission method and equipment configuration that does not require noise prevention processing and other processing may be used, and the image data transmission device portion can be reduced in size and weight, so that it can be contained in a spherical casing. Specifically, the spherical casing can be smoothly driven and rotated by driving from the lower surface side while maintaining the weight balance. Therefore, the monitoring direction change of the monitoring camera only needs to drive the casing mounted on the detachable camera in response to the control instruction signal from the remote control unit, and the casing and the receiving means 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. Thus, the monitoring direction of the monitoring camera 10 can be smoothly and effectively changed by a simple mechanism, and effective monitoring can be executed by the monitoring image from the monitoring camera 10. In this case, since the casing 20 is formed in a spherical shape, monitoring in all directions can be effectively performed. Further, since the first and second rollers 522 and 524 for rotating the casing 20 along the vertical plane and the third and fourth rollers 526 and 528 for rotating the casing 20 along the horizontal plane are provided. By combining them, the casing 20 can be rotated in the vertical and horizontal directions, and the direction of monitoring can be quickly and freely operated by visually grasping the position of the intersection on the monitor screen of the remote control unit. Can be changed to In addition, since the rollers 522 to 528 are in close contact with the casing 20 only when necessary by the contact / separation control unit and can be retracted in other cases, the monitoring direction can be changed more smoothly.

  Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and various modifications, improvements, and combinations can be made without departing from the matters described in the claims. It will be obvious to those skilled in the art. For example, in the above embodiment, the case where a camera is mounted as a monitoring unit has been described as an example. However, in the present invention, for example, a projector or a directional sound collector attached to a monitoring system, a radar, or a magnetic direction measurement A desired monitoring means such as a vessel can be mounted and applied. In the above embodiment, the monitoring direction is configured to be controlled remotely. However, the present invention may be applied to a monitoring system based on preprogrammed control or tracking control. In the above embodiment, the monitoring camera itself is fixed to the casing and the monitoring direction is changed by driving the casing. However, a driving mechanism for further changing the monitoring direction of the monitoring camera is provided in the casing. It may be driven by wireless control from the side and monitored at a wider angle.
