MOBILE LED SIGNS
Our new generation VMS takes advantage of leading edge technologies to provide the very best in variable message board systems. Improvements to both the message sign and trailer sub-systems provide an overall package that is easier to use, easier to transport, and more significantly lower maintenance costs.
Some of the message features include; message scrolling, multiple messages alternating/switching resulting in animation/scrolling of your message. Also, different messages can be pre-programmed based on the time-of-day.
The VMS system comprises of two primary sub-systems, the messaging board itself and the supporting trailer and power sub-systems. Including the hydraulic system.
Message board sub-system
The message board is manufactured in marine grade aluminum which is powder coated. This gives the message board a long life and will never rust.
The message board is available in three standard sizes:
Small – 1830 x 1040 mm (56 pixel wide and 30 pixels high, 1 LED per pixel);
Standard – 2400 x 1550 mm (48 pixel wide and 30 pixels high, 4 LEDs per pixel); and
Custom – any custom size is also available on application.
All boards have a standard 320/400mm character height and support full graphics mode for display of pictures as well as text together. Using the 320mm character size, the large board supports 10 characters per line (single spacing) and 8 characters per line (double spacing), with 3 lines of text.
The board’s face is made of high impact resistant Lexan which is able to withstand almost any act of vandalism.
Each pixel is powered by 1 or 4 amber LEDs with automatic brightness control for optimal power usage and extended battery life.
A standard feature on the message board is a connection from a computer (laptop) to control and program over 2000 messages.
The new generation VMS has a new streamlined trailer design. The new torsion bar suspension designed for Australian conditions dramatically improves the towing capability of the unit. This also reduces vibration on electronic components in the unit, during transportation, thus reducing overall maintenance costs and failure rates.
The new streamlined trailer design results in a lower working platform with easy access provided by a set of integrated steps. These improvements reduce the likelihood of accidents and provides an overall safer system to operate and work on.
The VMS is painted with high quality industrial 2-pack paint in any colour of your choosing.
However, standard safety colours such as white, yellow and orange are highly recommended. The 2-pack paint system will ensure maximum life of the unit and minimise through-life maintenance costs.
The VMS is powered by a set of heavy duty deep-cycle lead acid batteries charged via a pair of 80 or 125 watt solar panels.
The solar panels are mounted on a custom mounting rail that will allow full 360 degree rotation and angular adjustment independent of the message board’s orientation . The combination of the angular adjustment and rotation allows for maximum efficiency of the solar panels to minimise outages and the use of the diesel back-up system.
The back-up system is a single cylinder diesel engine with a direct drive coupled generator (meaning no belts to reduce maintenance). This system will automatically activate to recharge the batteries only when battery power is low due to extended periods of poor weather conditions that have reduced the ability for the unit to recharge.
This combination of solar, battery, and diesel will ensure continuous operation of the VMS even during extended periods of extremely poor weather conditions, especially in cold climate regions.
The back-up diesel engine is managed by a sophisticated engine management system. This avoids over-charging of the batteries, extending battery life, and avoiding operation of the motor during back-out hours for operation in noise sensitive areas, such as residential areas.. A further sound reduction option is also available.
Safety has been a major focus of the this generation VMS with many new safety features added over the previous model. These features include:
Board lowering protection, so the user cannot lower the message board if its not in alignment for its’ transportation position;
The board cannot be lowered if the board’s orientation brake has not been released;
Integrated steps to aid access to the working platform with anti-skid surface for added safety;
Lower working platform to reduce the risk of injury;
Security has also been a major focus of the new generation VMS with many new security aware features added over the previous model. These features include:
Tamper-proof locks on all access panels as standard;
Very rugged construction to reduce the likelihood of theft and vandalism;
Complete coverage of the under-carriage to restrict access to the internals of the VMS;
All out-rigger stands are chain welded to stop removal and theft of these stands.
How it Works
The overall operation of the VMS has been simplified with an easy push-button operation for raising and lowering the message board via a low maintenance hydraulic ram. The message board has full 360 degree rotation independent of the orientation of the solar array and can be locked into any position. The message board can be operated at any extension up to a maximum height of 3.4 metres.
The message board with 3 lines of text each with 9 characters will draws approx 5 amps. The standard battery configuration will operate for up to 40 hours at 10 amps continuous. The two 125 watt solar panels provide, under standard sunny conditions, approx 13 amps.
Therefore, under standard sunny conditions the message board will operate with a surplus of 9 amps to recharge the batteries as a result of night time operation.
The diesel backup system will recharge the batteries to full capacity in less than 3 hours and can operate for over 40 hours of diesel operation (i.e. approx 13 full recharges without refuelling) .
The combination of low power usage, high solar output and a diesel backup system means many months of unattended operation.
Fully configurable to suit your needs
The new generation VMS can be optioned to suit your specific application and needs. These options include:
Sound reduction option, which include an enhanced quieter muffler, sound insulation inside the motor compartment, and a sound reduction fiberglass cowling over the motor’s air intake manifold.
Swing out-rigger stands, which allow for easy and fast application of the outrigger legs as well as speedy pack-up for simplified transporting of the unit.
Lift-open Front Panel (standard), which allows for simpler and easy maintenance and cleaning of the unit’s lexan screen for optimal performance.
Integrated Speed Radar, which allows you to display different messages based on the detected speed, or include the actual speed on the screen, This option also includes a passive logging function which will log vehicle speeds over a 24 hour period that can be downloaded for further analysis.
GSM modem (standard), which allows for connection via the controlling computer to update and download new messages to the unit via the remote GSM modem installed in the unit.
CDMA modem, which allows for connection via the controlling computer to update and upload new messages to the unit via the remote CDMA modem installed in the unit when GSM coverage is not available.
Removable Towbar; which stops unauthorised towing of the VMS unit, since the towbar is removed from the trailer.
GPS Satellite Tracking, which provides real-time tracking of your VMS unit via satellite tracking. Alarms can be setup so you are alerted as soon as the unit has been moved. Alarms are also available when unauthorised opening of any door on the VMS unit. The GSM modem option is not required with this option since this option includes a GSM modem.
Handheld controller, which allows via a simple to use handheld controller to change the board’s messages to any of the 255 pre-programmed messages within the units memory without the need for a computer connection. This option provides a lower cost field unit to change the board’s messages.
110/240 Volt Power option, which allows the unit to be powered from a standard domestic 110/240 volt power outlet.
Battery /Solar Only option includes a larger battery package and no diesel back-up motor for recharging. The batteries are supported by the two 125 watt solar panels. This option is designed where ultra-quiet operation is mandatory and no motor noise is permitted.
Radial tyres for improved transportation when unit requires extended towing,
Leaf springs, as option (Torsion Bar as standard).
