STS-BL2000 Cabinet Processor

The SmarTek Systems, Inc. STS-BL2000 is a low cost and rugged programmable interface used as a custom interface between various remote sensors (loop detectors, traffic, weather, temperature, etc.) and a standardized Remote Processing Unit (RPU) or for use as a stand alone cabinet processor. By using the STS-BL2000 to poll for and/or service periodic sensor measurement messages and then communicating with the cabinet RPU, software and processing functions in the RPU can be kept generic (traffic flow, weather information, etc.) independent of sensor type, model, or brand. The STS-BL2000 requires little power and has a very small foot print. The STS-BL2000 may be used as a flexible custom interface for loop detectors and other devices without a serial data stream. All components are on a compact board for easy integration and roadside installation. The STS-BL2000 provides cost effective data collection, cabinet processing and data archiving without having to utilize the full power of a T-Box at sites where image capture is not an option.  It is highly recommended as a companion controller to replace much more expensive Type 170 or 2070 controllers for traffic monitoring if an ASCII data stream similar to the SAS-1 traffic message is desired.  By using this controller, traffic data from loop detectors can be collected, volume, lane occupancy, and average speed over a selectable interval can be calculated and sent just like the SAS-1 detector system, simplifying programming at Traffic Control Centers.  Each device can handle up to 10 relay outputs (see below) from a standard card file or shelf mount loop detector.  Easily set up using SmarTek Systems SAS Monitor and Display program.
