JP-A-7-186832 Japanese Patent No. 3314263

  However, in the case of the wing vehicle as shown in FIG. 5 described above, the left and right wing roofs 8 are deployed upward, so that the imaging position of the surveillance camera attached to the upper part of the cargo compartment 1 is the position of the wing roof 8. It changes due to opening and closing, and it is not possible to monitor the cargo compartment while the wing roof 8 is deployed and the cargo is being loaded or unloaded, or the cargo compartment can only be monitored while the cargo is being loaded or unloaded. There was a problem.

  In addition, the harnesses (signal cables and power cables) of the surveillance camera are pulled and tensioned when the wing roof 8 is expanded upward, and when the harness is lowered and closed, the margins of the harnesses sag and hang down. There is also a problem that there is a problem that it is difficult to arrange the harnesses so that there is no hindrance corresponding to the opening and closing of the wing roof 8.

  The present invention has been made in view of the above-described circumstances. It is possible to stably monitor the cargo room with a monitoring camera regardless of whether the wing roof is opened or closed, and easy to arrange the harnesses of the monitoring camera. An object of the present invention is to provide a cargo compartment monitoring device for a wing vehicle.

  The present invention is a cargo compartment monitoring device for a wing vehicle equipped with a pair of left and right wing roofs covering an upper surface and a side surface of a cargo compartment so as to be able to be expanded upward, and both the vehicle cabin direction intermediate positions on the upper surface of the cargo compartment. A surveillance camera attached to a connecting member that tiltably connects the wing roof, an information processing device for inputting image data in the cargo compartment by the surveillance camera, and image data in the cargo compartment from the information processing device. And a monitor that inputs image data in the cargo compartment from the information processing apparatus and transmits the image data to the base station.

  Thus, in this way, by attaching the surveillance camera to the connecting member of the wing roof, even if the wing roof is opened and closed, the surveillance camera is disposed at the intermediate position in the vehicle width direction on the upper surface of the cargo compartment. Since the imaging position of the monitoring camera does not change, the cargo room can be stably monitored by the monitoring camera regardless of whether the wing roof is opened or closed.

  As a result, while the wing roof is being unloaded and loaded and unloaded, the driver can monitor the condition of the luggage in the luggage compartment (whether it has collapsed) while driving with the wing roof closed. It is possible to confirm whether or not the loading space is available at a remote base station based on the image data transmitted by the communication device.

  Also, surveillance camera harnesses (signal cables and power cables) may be pulled and tensioned due to the upward deployment of the wing roof, or the harness margins may sag and hang down when lowered and closed. Therefore, it is easy to arrange the harness of the surveillance camera.

  Further, in carrying out the present invention more specifically, the information processing apparatus is a digital tachograph with a built-in drive recorder, and image data and audio data before and after the occurrence of an accident are recorded by the digital tachograph and are communicated to the base station. It is preferable that the position information is transmitted together with the image data transmitted from.

  In addition, a center beam extending over the entire length of the cargo compartment is provided at the end of the wing roof on the interconnecting side, and the center beams can be tilted with a hinge member as a coupling member at a midway position in the longitudinal direction of the cargo compartment. When a wing vehicle of a double center beam type connected to is used as a target, a monitoring camera may be attached to a portion of the hinge part that does not interlock with the wing roofs.

  Furthermore, it is preferable that the surveillance cameras are arranged at two locations that divide the entire length of the cargo compartment into three equal parts, and in this way, the entire area of the cargo compartment can be efficiently covered with only two surveillance cameras. Even if one of the surveillance cameras is directly underneath one of the surveillance cameras and the luggage is piled up to the top of the luggage compartment, it is possible to continue to supplement the photography with the other surveillance camera.

  According to the above-described cargo compartment monitoring device for a wing vehicle of the present invention, various excellent effects as described below can be obtained.

  (I) According to the first to third aspects of the present invention, the cargo compartment can be stably monitored by the monitoring camera regardless of whether the wing roof is opened or closed. You can check the status of your baggage (whether it hasn't collapsed) at any time, and even the remote base station knows the availability of the loading space based on the image data sent by the communication device, and the current wing vehicle It is possible to realize efficient operation by checking if there is a request for the collection of luggage in the vicinity, and the surveillance camera harnesses (signal cable and power cable) are deployed above the wing roof. The harness of the surveillance camera is easy because it is not tensioned by being pulled by or pulled down and closed, and the harness margins will not sag and hang down. It is also possible to cabling.

  (II) According to the invention described in claim 4 of the present invention, it is possible to efficiently cover the entire area of the cargo compartment with only two surveillance cameras, and to keep the equipment cost low, and Even if a load is piled up just below one of the surveillance cameras to the very upper surface of the cargo compartment and the photographing is impossible, the other surveillance camera can continue to supplement the photographing.

It is the schematic which shows an example of the form which implements this invention. It is an arrow view of the II-II direction of FIG. It is sectional drawing which shows the example of application to a wing vehicle of a double center beam type | mold. It is sectional drawing which shows the example of application to a wing vehicle of a single center beam type | mold. It is the perspective view which looked at the common wing vehicle from diagonally backward.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 and FIG. 2 show an example of an embodiment for carrying out the present invention. A pair of left and right wing roofs 8 having an L-shaped cross section so as to cover the upper surface and side surfaces of the cargo compartment 1 as described above with reference to FIG. 1 shows a cargo room monitoring device applied to a wing vehicle equipped with a wing that can be deployed upward.

  The cargo compartment monitoring device includes a surveillance camera 10 attached to a connecting member that tiltably connects the wing roofs 8 at an intermediate position in the vehicle width direction on the upper surface of the cargo compartment 1, and a cargo by the surveillance camera 10. A digital tachograph 14 (information processing device) with a built-in drive recorder that inputs image data in the compartment 1 and the image data in the cargo compartment 1 are input from the digital tachograph 14 and the image in the cargo compartment 1 is displayed at the driver's seat. A monitor 11 for display and a communication device 13 for inputting image data in the cargo compartment 1 from the digital tachograph 14 and transmitting the image data to the information center 12 (base station) are configured.

  Here, in the digital tachograph 14 built in the drive recorder, image data and audio data before and after the occurrence of the accident are recorded by the digital tachograph 14 and are transmitted along with the image data transmitted from the communication device 13 to the information center 12. Also comes to be sent.

  There are various types of pivot structures for the wing roofs 8 of the wing vehicle. As shown in FIG. 3, in this embodiment, the cargo room is located at the end of the wing roof 8 on the interconnection side. The center beam 15 extending over the entire length of the center 1 is provided, and the center beams 15 are wings of a double center beam type in which the center beams 15 are connected to each other in a tilting manner at the midway position in the front-rear direction of the cargo compartment 1 with the hinge part 16 as a connecting member. The surveillance camera 10 is attached to a portion of the hinge part 16 that is not interlocked with the wing roofs 8 for a vehicle.

  That is, the hinge part 16 is composed of a hinge body 16a and wing parts 16c provided on both sides via pins 16b so as to be tiltable. The wing parts 16c are formed on the side surfaces of the center beam 15 of the wing roof 8. Since the hinge main body 16a is a part not interlocked with the wing roof 8, the surveillance camera 10 is attached to the end face of the hinge main body 16a facing downward.

  At this time, most of the surveillance camera 10 is accommodated in the space between the center beams 15, and the front ends slightly protrude from the lower surfaces of the center beams 15 in a state where the wing roofs 8 are closed. In this way, interference with luggage is avoided as much as possible.

  In the case of such a double center beam type wing vehicle, the front and rear ends of both center beams 15 are pivotally supported at the upper center of each of the front wall 4 and the rear gate frame 6 of the luggage compartment 1. 15 are connected to each other by a hinge part 16 so as to be tiltable to each other. These hinge parts 16 are in a state of floating in the air and are fixed from the vehicle body side. It is not.

  However, as described above, since the front and rear ends of both center beams 15 are firmly supported by the front wall 4 and the rear gate frame 6 of the cargo compartment 1, the position of the tilt axis of each wing roof 8 is automatically determined. The position of the tilt axis is not changed in each hinge part 16, and the posture of each hinge part 16 is not greatly changed by opening and closing the wing roof 8.

  Further, in the example shown here, two monitoring cameras 10 are installed, but the hinge parts 16 arranged at two places that divide the entire length of the cargo compartment 1 into three parts are selected. For example, if the total length of the cargo compartment 1 is 6 m, the surveillance cameras 10 are installed at the 2 m point and the 4 m point facing backward from the front wall 4.

  Note that reference numeral 17 in FIG. 3 denotes a cover made of a flexible resin sheet, which covers a gap formed between adjacent portions of the wing roofs 8 so as to prevent rainwater or the like from entering the cargo compartment 1. Yes.

  Thus, if the cargo compartment monitoring device for a wing vehicle is configured in this way, the monitoring camera 10 is attached to the hinge part 16 so that the position of the monitoring camera 10 can be arranged even if the wing roof 8 is opened and closed. Is maintained at the intermediate position in the vehicle width direction on the upper surface of the cargo compartment 1, and the imaging position of the surveillance camera 10 does not change. It becomes possible to monitor stably.

  As a result, while the wing roof 8 is being unloaded and loaded and unloaded and the wing roof 8 is closed, the driver can monitor the condition of the luggage (loading) in the luggage compartment 1 using the driver's seat monitor 11. It is possible to check at any time whether or not it has collapsed, and based on the image data transmitted by the communication device 13, the remote information center 12 can also grasp the availability of the loading space.

  In addition, the harnesses (signal cables and power cables) of the surveillance camera 10 are pulled and tensioned by the upward deployment of the wing roof 8, or when the harnesses are lowered and closed, the margins of the harnesses sag and hang down. Therefore, it is easy to arrange the harnesses of the monitoring camera 10.

  In addition, in this embodiment, the monitoring cameras 10 are arranged at two locations that divide the entire length of the cargo compartment 1 into three parts, but this arrangement is variously arranged by the present inventors using two monitoring cameras 10. It has been confirmed that it is the most effective in trying out the patterns, and it is possible to efficiently cover the entire region in the cargo compartment 1 with only two monitoring cameras 10.

  Note that the two surveillance cameras 10 are taken even if one of the surveillance cameras 10 is directly underneath one of the surveillance cameras 10 and the luggage is stacked up to the upper surface of the cargo compartment 1 so that photographing is impossible. However, the reason why the number of units is not three or more is to keep the equipment cost low by limiting the number of units to the minimum number that can cover the entire area of the cargo compartment 1.

  Therefore, according to the above embodiment, the inside of the cargo compartment 1 can be stably monitored by the monitoring camera 10 regardless of whether the wing roof 8 is opened or closed. The situation (whether or not the cargo has collapsed) can be checked at any time, and the remote information center 12 can grasp the empty space of the loading space based on the image data transmitted by the communication device 13, and the current wing vehicle It is possible to check whether there is a request for picking up the baggage nearby, and to realize efficient operation. Moreover, the harnesses (signal cable and power cable) of the surveillance camera 10 are located above the wing roof 8. When the surveillance camera 10 is pulled by being unfolded and tensioned, or when it is lowered and closed, the margin of the harnesses does not sag and hang down. The harness such easily may be routed.

  Moreover, since the surveillance cameras 10 are arranged at two locations that divide the entire length of the cargo compartment 1 into three parts, the entire area in the cargo compartment 1 can be efficiently covered with only two surveillance cameras 10. The equipment cost can be kept low, and even if one of the surveillance cameras 10 is directly underneath one of the surveillance cameras 10 and the luggage is piled up to the top of the cargo compartment 1, the other surveillance camera 10 can take a picture. Can be supplemented continuously.

  3 illustrates the case of a double center beam type wing vehicle, but as shown in FIG. 4, an intermediate position in the vehicle width direction on the upper surface of the cargo compartment 1 extends over the entire length of the cargo compartment 1. A single center beam type wing vehicle in which a single center beam 18 is fixedly installed as a connecting member and both wing roofs 8 are attached to both sides of the center beam 18 via hinge parts 19 so as to be tiltable is also applicable. Of course, in the case of such a single center beam type wing vehicle, the monitoring camera 10 is embedded in the center beam 18 and the tip of the monitoring camera 10 is slightly extended from the lower surface of the center beam 18. It is better to avoid the interference with the luggage as much as possible.

  Even in such a case, it is possible to achieve the same operational effects as the above-described embodiments of FIGS. 1 to 3, and more specifically, the inside of the cargo compartment 1 is monitored regardless of whether the wing roof 8 is opened or closed. Since it can be stably monitored by the camera 10, the driver can always check the status of the luggage in the luggage compartment 1 (whether the cargo has not collapsed) by the monitor 11 (see FIG. 1). Based on the image data transmitted by the communication device 13 (see FIG. 1), the remote information center 12 also grasps the availability of the loading space and confirms whether there is a request for the collection of luggage near the current wing vehicle. Thus, efficient operation can be realized, and the harnesses of the surveillance camera 10 can be easily arranged.

  The cargo compartment monitoring device for a wing vehicle according to the present invention is not limited to the above-described embodiment, and the monitor may be composed of a remote-controlled portable terminal that can be carried separately from the vehicle, In addition, it goes without saying that various changes can be made without departing from the scope of the present invention.
