TDC2 Series Dual-Technology PIR & US Traffic Detector for Traffic Counting, True Presence, Height Discrimination Features • • • • The TDC2 Series are advanced traffic detectors using Passive Infrared (PIR) and Ultrasonic (US) technology. Vehicle events (count) and distance (height) are provided via RS 485 databus, additional truepresence is available via relay output. Typical Applications ADEC TDC2 Series detectors is specifically designed for a variety of Traffic Data Collection and traffic control applications where true presence detection are required: Vehicle counting (volume) Traffic light control, green light request Object / vehicle true presence detection Detection of standing vehicles True-presence detection Vehicle discrimination by height Distinguish cars from trucks and busses Dual-sensor detection Responsive action combined with true presence detection Auto calibration Auto calibration using distance / height thresholds via dedicated commissioning software Wide mounting height range Detection range up to 10 meters (33 ft.) Application-dependent limitations apply Wide operating temperature range –30 to +65°C (–22 to +149ºF) Optimal performance in all weather and climate conditions Remote configuration and setup With dedicated commissioning and installation software Stop-bar loop replacement Vehicle discrimination by height Working principle TDC2 traffic detectors employ PIR and US detection zones. A combination of static and dynamic detection channels form a total of two overlapping detection zones. The thermal radiation contrast of a vehicle moving into or through the detection zones against the background radiation of the road surface correlates to the passage of a vehicle, the changes in distance from the detector provide information about the presence and/or height of a vehicle. Sophisticated algorithms transform the sensors data into height, occupancy and directional information for each event without the need for external computing equipment. Mounting Recommended mounting points are gantries, overpasses or bridges or alternatively on a pole at the roadside. Clearly superior performance and reliability are a result of: Quad-channel PIR detection combined with single US zone Full temperature compensation across entire temperature range Sophisticated algorithms eliminating impact of environmental changes ADEC Technologies AG ● Gublenstrasse 1 ● CH-8733 Eschenbach SG
