SPEED DISPLAY SIGNS: SDU1000 Speed Sign   PRINCIPLE OF OPERATION The Inter-active sign will display a real-time illustration of the approaching speed of an oncoming vehicle when exceeding a pre-set threshold limit. However, if the approaching vehicle is above a secondary higher threshold limit, the sign will display both SPEED and SLOW DOWN. If the vehicle then slows down and the speed falls below the secondary threshold limit, the sign will display THANK YOU with the real-time speed. To eliminate the possibility of drivers attempting to have a high speed displayed, a third higher threshold limit can be set. This allows the safety message of SLOW DOWN to display, without the real-time speed being displayed. SITING & OPERATION The sign must be sited, such that the approaching vehicle, can be detected and the sign observed, allowing the driver time to take appropriate action. MOUNTING Normally a 76mm O.D. large base post is adequate, with a 230v 50Hz, supply to the base of the post. An alternative to the above is a tripod assembly, which allows the sign to be placed by the roadside. The sign is easily transported, due to the assembly being able to be assembled from it's 3 basic components, viz Sign, Tripod & Legs. CONSTRUCTION All aluminium body, with a clear polycarbonate lense. The rear of the sign has two channel rails. DIMENSIONS Sign width 650mm Sign height 700mm Sign depth 40mm Sign weight 12Kg ELECTRONICS Solid state electronics which in conjunction with the Light Emission Diods (LED's) for the display, an operational life of 100,000 hours is anticipated. DATA RECORDING FACILITY The SDU1000 has the capability of recording the number of displays, percentile speeds, time & date stamps, and other information, this can be downloaded into your computer and placed in to a Microsoft Excel file using the macros facility. From there the information can be displayed in any chart formation, giving that professional finish to your evaluated statistics.
