Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem that a standing signboard is a still picture and whose visual effect is small and an outdoor projector with high visual effect costs a great deal as outdoor advertisement. <P>SOLUTION: This outdoor automatic image projection system is characterized in that an image is projected on an outdoor screen by automatic control by combining a commercial personal computer and a liquid crystal projector. Thus, the outdoor projector with high visual effect is introduced at a low cost and operated by using commercial products for indoors. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a configuration of an image projection system used for outdoor advertising or the like.

For standing billboards used for conventional outdoor advertisements, etc., it is difficult to respond immediately because it is requested to change the contents of the advertisement after the installation, and it is expensive. Of course, there are only still images.
When a conventional outdoor image projection system or the like is used, it is possible to immediately respond to changes in the image contents, but since there are many specialist contractors who perform system installation and maintenance management, the operation cost is considerably high.

However, according to the above technology, the screen installation cost for image projection is almost the same as the billboard installation cost, the personal computer and liquid crystal projector used for the image projection system use commercially available products, and the installation cost is the conventional image projection system It is considerably cheaper than
In terms of maintenance management, all items requiring maintenance are commercially available and can be performed by the manager himself without requesting a specialist.
In terms of image content change, since it is performed by changing information in the personal computer, the administrator can change the content to the intended image and change the projection time immediately.
Therefore, an object of the present invention is to provide an outdoor automatic image projection system that can project an image intended by an administrator easily and inexpensively.

In order to solve the above-mentioned problems, the first invention is an outdoor image projection system characterized in that a commercially available personal computer and a liquid crystal projector are combined and an image is projected onto an outdoor screen by automatic control.
The second invention is an outdoor image projection system characterized in that the projection content can be easily and inexpensively changed.

  According to the first invention or the second invention, an image intended by the administrator can be projected onto the outdoor screen easily and inexpensively, and maintenance management after installation can be easily and inexpensively performed.

One embodiment of the present invention is shown in FIG.
The outdoor automatic image projection system main body 1 is made of iron and is an integral type that is waterproofed.
The main body 1 is divided into a projector room 3 and a personal computer room 4.
The projector room 3 has a liquid crystal projector 6 and a cooling fan 7 as shown in FIG.
As shown in FIG. 3, the personal computer room 4 has a personal computer 8, a cooling fan 9, a DC power supply 10 for driving the cooling fan, a calendar timer 11 for power control, and a terminal block 12 for connecting wirings. .
A power plug 5 for connecting to a commercial power source is provided from the lower part of the personal computer room 4 as shown in FIG.
An outdoor screen 2 for projecting an image projected by the outdoor automatic image projection system main body 1 is installed.
The commercial power supplied from the power plug 5 is supplied to each of the liquid crystal projector 6, the personal computer 8, and the calendar timer 11.
When the calendar timer 11 is operated at an arbitrarily set time, the personal computer 8 is turned on and the internal automatic projection software is started. In the automatic projection software, the projection start time, projection end time, and projection image selection can be arbitrarily set.
The cooling fans 7 and 9 connected to the DC power supply device 10 are controlled by connecting and shutting off the power supply of the DC power supply device 10 by operating the calendar timer 11 at an arbitrarily set time.
When the projection start time is reached by the automatic projection software activated inside the personal computer 8, the power on of the liquid crystal projector 6 is controlled, and a projected image is output from the personal computer 8 to the liquid crystal projector 6.
When the projection end time is reached, the power-off control of the liquid crystal projector 6 is performed, the output of the projected image is stopped after confirming the power-off, and the power of the personal computer 8 is turned off with automatic projection software after a certain time.
Thereafter, automatic projection is performed automatically every day.

"Effect of the embodiment"
According to this embodiment, an image intended by an administrator can be provided to a large number of people easily and inexpensively.
Conventional outdoor advertising systems include a stand-up sign format, a small-scale outdoor projection system, and a large-scale outdoor projection system that cannot change the contents.
The advantage at the start of installation and introduction is that the installation of the outdoor screen 2 in FIG. 1 can be installed in any size as well as the billboard, the cost is about the billboard, and the equipment of the main body 1 in FIG. It is only used and a commercial power supply is prepared for incidental work. For small and large projection systems, the equipment is expensive, and for large systems, additional work is required for large-scale work such as telephone lines and communication cables, resulting in considerable costs.
Although the maintenance method is small and large, the management company or the manufacturer makes it costly. However, in this system, since the equipment used is composed of commercially available products, the administrator himself can do it.
In addition, when the device becomes unusable due to a device failure or the like, a replacement device can be prepared immediately, and the recovery work is quickly performed by the manager himself.
When drawing or projecting an image intended by the administrator, it is time-consuming and expensive to submit the desired image to the signer in the form of a signboard and replace the signboard, and cannot be corrected.
Since this system uses images, moving images, and the like created with commercially available image editing software on a personal computer other than the personal computer 8 of FIG. 1, it can be created even by an administrator who does not use specialized knowledge.
Even with the ease of changing the image to be projected, it is only necessary to copy the image created as described above into the personal computer 8 of FIG.
For small and large scale systems, there are cases where the same method as this system is used, but since there are many cases where the management company manages the system, it is costly to simply change the image.

"Other embodiments"
In the embodiment of FIG. 1, the liquid crystal projector 6 and the personal computer 8 are installed in the main body 1. However, in other embodiments, the liquid crystal projector 6 and the personal computer 8 may be divided according to the installation location.

It is a perspective view showing one embodiment of this invention. FIG. 2 is a detailed perspective view of the projector chamber 3 of FIG. 1. FIG. 2 is a detailed perspective view of the personal computer room 4 in FIG. 1.
