The base plate 48″ also includes anchor points 132″ that are arranged to anchor the display system 20″ to a surface (e.g., the ground, a concrete slab, a floor, a wall, a ceiling, etc.). In the illustrated embodiment, the anchor points 132″ include apertures arranged to receive fasteners.
The top cap 52″ is arranged to be welded onto the main upright back 40″ and the main upright front 44″. In other embodiments, the top cap 52″ may be fastened to the main upright back 40″ and the main upright front 44″ and provide a seal.
The four mounting arm plates 56″ are fastened to the main upright back 40″ and the main upright front 44″ either with fasteners, welding, or another coupling mechanism. In some embodiments, less than four or more than four mounting arm plates 56″ may be provided. The four mounting arm plates 56″ are arranged to support the four mounting arms 60″.
The mounting arms 60″ are sized to support three larger format displays 24″. In other embodiments, the mounting arms are arranged to support a single large format display (e.g., the mounting arms 60 shown in
The speaker grill 64″ and the speaker box 68″ are arranged to engage the speaker aperture 116″ and the microphone aperture 120″ and provide a speaker and a microphone that a user can interact with. In other embodiments, the speaker grill 64″ and the speaker box 68″ are replaced by another communication device as discussed above, or eliminated.
The vents 72″ engage the vent apertures 112″ and provide air flow to an interior of the column 28″. The cover plates 76″ engage the vent apertures 112″ and seal various components within the column 28″. In other embodiments, more than two vents 72″ or less than two vents 72″ may be used. In other embodiments, more than two cover plates 76″ or less than two cover plates 76″ may be used.
The gusset plates 80″ are arranged within the column 28″ and modify an airflow within the column 28″. Additionally, the gusset plates 80″ are arranged to manage humidity flow or fluid flow within the column 28″ such that the column 28″ meets the IP56 standard.
The three industrial PCs 84″ are positioned within the column 28″ and each interacts with a single large format display 24″ and provides information to be shown on the corresponding larger format display 24″. In other embodiments, a single industrial PC 84″ may provide display information to more than one large format display 24″.
The network switch 88″ provides communication between the industrial PCs 84″ and an external or remote controller or network. The network switch 88″ may provide wired or wireless communication such that the images displayed by the large format displays 24″ may be controlled or manipulated.
The a surge protector outlet strip 92″ provides power to the various systems within the column 28″. In some embodiments, the surge protector outlet strip 92″ may be replaced by a power bus, or the components may be individually wired to the power supply, or an external power source (e.g., line power).
The three cooling fans 96″ are arranged adjacent the lower most vent plate 72″ such that the column 28″ is maintained in a generally positive pressure environment. In other words, the pressure within the column 28″ is maintained above atmospheric pressure by the fans 96″. The gusset plates 80″ also aid the column 28″ in maintaining a positive pressure environment by providing a partially reduced airflow path. The increased pressure environment reduces the likelihood of humidity and moisture infiltrating the inside of the column 28″. In other embodiments, more than three or less than three fans 96″ may be used.
The main circuit connection 100″ is connected to an external power source such as a main power line (e.g., 110 VAC, 220 VAC) and provides power to the a power supply 104″. The main circuit connection 100″ is housed in the junction box 108″. The power supply 104″ receives power from the main circuit connection 100″ and converts the main power line to a DC current for use by system components.
An exemplary control circuit 136 is shown in
The termination box 140 is arranged to receive external power in the form of line power 184 (e.g., 110 VAC or 220 VAC) and is in electrical communication with the junction box 144, the monitor supplies 160, and the DC power supplies 164. In one embodiment, the termination box is the junction box 108″ discussed above.
The junction box 144 may be a 4-plex junction box and provides power to the power strip 148. In one embodiment, the junction box 144 is the main circuit connection 100″ discussed above. The power strip 148 distributes line power to the media player 152, the router 156, and the fiber converter 176. In one embodiment, the power strip 148 is the surge protector outlet strip 92″ discussed above.
The media player 152 receives power from the power strip 148 and delivers image signals to the monitors 180 via cables in the form of DVI cables 188. In other embodiments, different cable types may be used to transmit signals between the monitors 180 and the media player 152. In one embodiment, the media player 152 includes industrial PCs 84″ as discussed above. For example, one media player 152 may be provided for each monitor 180, or the media player 152 may provide signals to more than one monitor 180. In some embodiments, the media player 152 is another type of controller, processor, or computing device, as desired.
The router 156 is in communication with the media player 152 and the fiber converter 176 via cables in the form of CAT5e cables 192. In other embodiments, different cable types may be used to transmit signals between the router 156, the media player 152, and the fiber converter 176. The router 156 is also in communication with a remote network, in the form of a patch panel or and external antenna via cables in the form of DVI cables 196. In other embodiments, different cable types may be used for communication with the router 156.
The monitor power supplies 160 receive power from the termination box 140 and provide conditioned power to the monitors 180 via low voltage wires or cables 200. In some embodiments, the monitor power supplies 160 may be housed within a housing of the monitor 180 (e.g., the housing 32 of the large format display 24). In other embodiments, the monitor power supplies 160 may be housed within a support structure (e.g., the column 28). In some embodiments, each monitor power supply 160 provides power to more than one monitor 180.
The DC power supply 164 receives line power from the termination box 140 and converts the line power to a conditioned DC power that is provided to the thermostat 168 via a low voltage wire or cable 204. The thermostat 168 monitors the temperature of the control circuit 136 and operates the fans 172 to maintain the temperature within a desired temperature range. When the thermostat 168 determines that cooling is needed power is delivered via low voltage wire or cable 208 to the terminal box 170 where the power signal is then distributed via low voltage wires or cables 212 to the fans 172.
The fiber converter 176 receives a fiber optic cable 216 and is configured to interpret signals received from the fiber optic cable 216 and deliver the interpreted signals to the media player 152 so they may be displayed on the monitors 180.
In one embodiment, all components of the control circuit 136 are housed in the column 28 except the monitors 180. The monitor 180 may be the LED board 36, and the low voltage wire or cable 200 and the DVI cables 188 may run between the housing 32 and the column 24 via the communication port 124 in the column 28.
In one embodiment, the thermostat 168 operates the fans 172 such that the fans 172 run substantially continuously. The thermostat 168 may be a pulse width modulated (PWM) thermostat that can control the fans 172 at a number of different speeds. For example, a minimum speed may be maintained at all times, and in times of cooling demand, the thermostat 168 operates the fans 172 at a high speed or any speed higher than the minimum speed as demanded by the level of required cooling. Continuously maintaining the fans 172 at a minimum speed may be especially advantageous in cold climates where snow and ice are an issue and may tend to cause the freezing of fans and other system components. In one embodiment, the fans 172 are operated at a minimum speed to avoid freeze up, and are operated at a maximum speed when the temperature of the control circuit 136 reaches ninety degrees (90°) Fahrenheit.
In one embodiment, most of the control circuit 136 may be housed in a remote location such as in a store or a quick service restaurant, and only the power components, fans, fiber converter, and the media player are positioned within the column. In other embodiments, different combinations of components may be included in the control circuit. For example, in some embodiments, the industrial PC(s) may be eliminated and information is sent directly to the monitors or large format displays. In some embodiments, the industrial PC(s) may be replaced with another controller, computing device, or processing circuit, as desired. In still other embodiments, various components of the control circuit may be housed in either the large format display or the support structure. The flexibility of the system allows for installation at a variety of locations with different demands. In some locations, the system may require other components not discussed herein that may be housed in the large format display or the support structure.
The column is arranged such that a positive pressure is maintained within the column such that particulate and moisture migration into the column is minimized. Additionally, the gussets and vents are arranged such that in the event of water migration (e.g., during an extreme weather event) the moisture will evaporate in an acceptable time frame to still meet IP56 standards for weatherproofing.
The above embodiments provide a number of advantages including the ability to provide a single column or support structure that houses control components and allows for simple and effective adjustment of the display layout and configuration. For example, the same column may be used for a single wide, a double wide, and the three wide display, as shown in
