Description

Remote monitoring system for large outdoor advertisements {A SYSTEM FOR REMOTELY MONITORING A LARGE-SCALED OUTDOOR ADVERTISEMENT}

The present invention mainly relates to a system for remote monitoring of large outdoor advertisements installed on the roof of a building.

In general, in the case of advertisements such as light-emitting large advertising tower mainly installed on the roof of a large building, the advertising effect is increasing day by day because the trend is increasing.

In addition, the advertising technique is also becoming more diversified and sophisticated. For example, initially disclosed in Korean Utility Model Publication No. 92-20165, a plurality of light bulbs are built into a steel structure surrounded by a large billboard to start with different still image advertisements depending on whether light is transmitted. As shown in Korean Utility Model Publication No. 99-15378, there are various methods such as an advertisement method having an electronic display panel expressing advertisement contents through a plurality of LEDs, or a method of dynamically changing a screen using a neon tube or even an LCD surface. There is this.

By the way, such large outdoor advertising inevitably maintains the advertisement. Maintenance issues follow. In other words, the light bulbs, LEDs, and neon tubes, etc., which have a limited lifespan, do not emit light or fail after a certain period of time. Dropped remarkably. Therefore, the broken advertisement must be caught immediately and repaired.

If the advertiser first discovered that such a failure had been left unattended, the advertiser would not be complained about the advertising company that installed it. It may even be the subject of a claim or cause termination of a contract.

Therefore, the advertising company should constantly monitor the advertisement surface. In the simplest way, the store clerk or the security guard who lives in the place where the advertisement is most visible in the past has given some gratuity and contacted when there is an abnormality in the advertisement screen. It was about asking you to do it. But of course this is problematic. If the watcher couldn't find a fixation due to vacation or urgent business, or poor visibility due to bad weather, etc., it couldn't detect fine breakdowns. The time interval of the monitoring is inevitably large. As a result, it is inevitable to reduce the credibility of advertising companies in managing their advertisements.

On the other hand, in the case of the conventional method, a designated monitor agent can monitor several sites in a short time, but monitors only a few advertisements because it is necessary to visit them directly, which is inefficient in time and administrative expenses. Of course, real-time monitoring was unthinkable.

In order to overcome this problem, one can think about the current method is to install a surveillance camera in the opposite building by using CCTV or surveillance camera, and transmit the captured image to the indoor monitor using a communication line for monitoring. . However, in this case, large outdoor advertisements installed on the rooftop of a building mostly use two or more large advertisement surfaces. Therefore, in order to monitor all advertisement surfaces, cameras should be separately installed in two or more buildings separated from each other. The cable must be pulled separately. Moreover, this type of advertisement is usually installed at the corner of a large street to increase the effectiveness of the advertisement, so the length of cable installation is excessively long, and the building lease with the landlord of the building where the advertisement is installed In order to install surveillance cameras separately, a separate building use lease must be signed. In some cases, such as a communication law may arise.

An object of the present invention is to install the two or more camera support on the advertisement itself in order to improve the above problems, and transmits the image taken through the two or more surveillance cameras supported on the camera support to the remote monitor, the state of the outdoor advertisement It is to provide a remote monitoring system for large outdoor advertisements to monitor the safety of steel structures and electrical safety, such as neon tubes and lights at all times.

Further objects and effects of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings.

Remote monitoring system for large outdoor advertisements according to the present invention for achieving the above object,

Two or more camera supports mounted on steel structures of outdoor advertisements and supporting cameras for photographing two or more advertisement surfaces; Means for modulating the captured video signal of each camera and transmitting the signals remotely via a pair of telephone lines; And means for receiving and demodulating the transmitted signal to display the photographed image, wherein the camera support is mounted on the steel structure and protrudes in front of the advertisement surface, and moves the repair ladder during repair of the advertisement. It can be withdrawn from the front of the advertising surface so as not to limit.

First, a state in which the camera support and the outdoor advertisement according to the present invention are installed will be described with reference to FIGS.

1 is a schematic diagram of a camera of a monitoring system according to an embodiment of the present invention installed in a large outdoor advertisement, FIG. 2 is an installation diagram of a camera support according to the present invention, and FIG. 3 is a part of a camera support according to the present invention. Exploded perspective view.

As shown in Fig. 1, a large outdoor advertisement mainly installed on a roof of a high road or a building located near a large road, a large billboard is disposed around the rectangular steel frame structure 2 installed in the building. 1 shows a front billboard 1 and a side billboard 1 ′. As described above, the repair ladder 4 for repairing the billboard is installed on the steel frame structure so as to be movable along the advertisement surface. The steel frame structure 2 is provided with a camera support 3 according to the present invention. In FIG. 1, two cameras are installed on the front and rear billboards and one on the left and right billboards.

More detailed installation state and structure of the support will be described with reference to FIGS. 2 and 3.

The support 32 which is placed in the vertical direction is mounted to the steel frame structure 2 by the support plate 31. One end of the support bar 33 is rotatably installed at a proper position of the support. That is, as shown in Figure 3, the pivot member 38 is fitted to one point of the support, the fastening portion 38a of the pivot member 38 is fastened with the fastening portion 33a of the support bar (33). Reference numeral 38b is a tightening bolt.

Support rod 33 is preferably to use a hollow tube to reduce its own weight and maintain a certain strength, it is possible to accommodate the cable of the camera in the hollow. The other end of the support bar is equipped with a monitoring camera, the other end of the support bar is preferably bent inward to have a bent portion 33b so that the camera naturally faces the advertisement surface when the camera is mounted. In addition, when the size of the advertising surface is approximately 10m * 16m, the camera must be protruding from the advertising surface at least 5m or more to shoot a single advertising surface with two cameras, so depending on the position of the steel structure on which the support is mounted Although there may be differences, the length of the supporting rod is preferably about 7 m.

On the other hand, three fastening portions 33c are provided at appropriate intervals in the middle of the supporting rods, and the fastening portions 32a are also provided at the tip of the support, and these are supported by the auxiliary support 34 and the first and second vertical connection wires 35. , 35 '). In other words, when the support is installed, the support rod is prevented from falling down by the vertical connection wires, and the support rod is supported by the support rod and the support rod to prevent the support rod from rising due to the strong wind.

On the other hand, when a failure is found on the advertising surface and needs to be repaired, the repair ladder 4 must be moved to the site to be repaired, and thus, the support must be recovered from all directions of the advertising surface. Therefore, the auxiliary support should be of a removable structure.

In addition, it is preferable to bind the binding portion 33c of the support rod to the steel frame structure through the first and second horizontal connection wires 36 and 36 'in both the left and right directions or in either direction. These horizontal connection wires should also be easily removable.

On the other hand, as a method of mounting the support (2) to the steel structure, as shown in Figure 4, without installing the support plate separately, such as by using a U-bolt (39) to directly support the structure of the steel structure You may bind to a vertical column. However, in this case, it is preferable in the management to fasten to the inner vertical column of the billboard is not adjacent among the vertical columns of the steel structure.

Another manner of the support for supporting the camera will be described with reference to FIGS. 5 and 6.

Fig. 5 is a schematic diagram in which a camera of a monitoring system of another embodiment of the present invention is installed in a large outdoor advertisement, and Fig. 6 is a camera support of the second embodiment.

The camera support 5 of the present embodiment includes a support rod 51 positioned at the corner portion where the advertisement surface meets, and the support rod 5 is fixed to the roof or steel structure of the building at the corner of the steel structure. The supporting rod 51 and the support 52 are bound by the stop pin 59 in the same manner as the connection between the flag holders. Therefore, when the stop pin is removed, the support is separated from the supporting rod. The support 5 'may be curved in some cases so as not to obstruct the field of view.

In addition, a support rod 53 for directly supporting the camera is connected to the support, and the horizontal connecting wire is connected to a suitable middle portion of the support rod and the upper end of the support to prevent the support rod from sagging down.

Unlike the support of the first embodiment, in this embodiment, the auxiliary support 54 holds the upper portion of the support and the steel structure, thereby preventing the support from flowing. Also in the repair of the advertisement surface, the auxiliary support should be detachable so that the repair ladder can move.

As in the first embodiment, it is preferable that the supporting rod 53 for directly supporting the camera is held on the roof of the steel structure or the building by the horizontal connecting wire 56.

The support of the second embodiment is not preferable when the advertising board is installed on all four surfaces, since the support covers a part of the advertising surface, and the camera photographing the side surface in the case of two-sided or three-sided advertising using only the front and side surfaces. It is preferable to install. That is, since the advertising surface is mostly long in the lateral direction, it is possible to photograph one side billboard with one camera if the advertising surface is photographed from the side of the advertising surface.

In some cases, the camera support of the first embodiment or the second embodiment may be installed so as to protrude from the bottom of the billboard. In this case, since the camera should look up while photographing the advertisement surface, the remote control wiper is attached to the lens portion of the camera. Although it is also necessary to install, since the monitoring camera which has a remote control wiper is commercially available, those skilled in the art will be able to easily modify and install.

A block diagram of a remote monitoring system according to the present invention will now be described with reference to FIG.

As shown in FIG. 7, cameras 1 to 3, which are installed in steel structures of advertisements, are often photographed by remote control. The captured video signal is signal-processed as a digital signal by the signal processor 6, modulated by the transmitting telephone modem 7 and transmitted along the telephone line, and then converted into a digital signal by the receiving modem 7 '. It is demodulated and displayed on the monitoring monitor of the central computer 8, for example, in Seoul. The transmitted images may be stored in the storage space for later selection and viewing.

8 is an example of a monitoring screen of a remote monitoring system according to the present invention, and FIG. 9 is another example of a monitoring screen of a remote monitoring system according to the present invention.

As shown in Fig. 8, when the cameras of the fifth region are selected on the browser screen of the central monitoring computer, images sent from the cameras there are displayed. The first and second cameras show the advertisement surface image of the front billboard 1, and the third and fourth cameras divide the advertisement surface image of the side billboard 1 '. For reference, portraits of people appearing on the advertisement surface are displayed to be hidden by cameras 1 and 2, and camera 5 displays images of surrounding roads so that advertisers can know the current road conditions and refer to the advertisement. did.

Fig. 9 shows an enlarged view of an image of camera # 3 suspected of a problem among images previously sent and stored in the storage space. It can be seen that a problem has occurred in the display board of the letter portion of "Samsung". Therefore, it is possible to promptly repair by instructing the repairman in charge of the area to immediately repair the corresponding part of the billboard.

Although the present invention has been described above with reference to one embodiment shown in the accompanying drawings, the present invention is not limited thereto, and various modifications may be made within a range easily understood by those skilled in the art. Therefore, the limitation of the present invention should be limited only by the following claims.
