SW3224 DETECTOR

The SW3224 loop detector was specifically designed for vehicle detection with classification and speed measurement for traffic data acquisition and traffic management. The detector is designed for DIN-rail mount and includes a complete overvoltage protection module for the inductive loops.

The SW3224 offers the features and outstanding characteristics of the SWARCO TRAFFIC SYSTEMS classification detectors in 19" technology now also in a device for DIN-rail mounting. Developed on the basis of the proven and certified MC2224 / CD9234, it includes a complete surge protection module. This integration minimizes the wiring and reduces the space requirement considerably.

The SW3224 classifies the vehicles in ASTRA*-SWISS classes (SWISS 10, SSVZ or car-similar/HGV-similar vehicles). When ASTRA-SWISS loops are used, the classification meets the accuracies required by the ASTRA and is not influenced by e.g. weather conditions.

On activation of the directional logic, reports of wrong way drivers can be generated. The vehicle type is determined by means of passing-curves which have characteristic features depending on the different classes and the loop types used.

Via the RS485 bus single-vehicle data is transferred to a controller, which takes over further data aggregation acc. to ASTRA specification. The detector automatically adjusts itself to the attached loop/feed-cable combination. Variations in temperature have no influence on data acquisition.

The measuring systems are permanently checked for short or open loops, only when a definite malfunction is detected, systems are put into a failure condition. If one loop of a double-loop system is disturbed, the remaining loop supplies further data on time of occupancy, time gap and a classification of car-similar and HGV-similar vehicles. Speeds and vehicle lengths cannot be determined.

Short measuring intervals and a new procedure for speed measurement provide for the high accuracy of the measured data and the high detection speed, according to the requirements of the Swiss federal roads office.

The LoopMaster operating program, which is available free of charge, offers extensive loop and detector analysis functions. The trend-setting customizing allows an individual configuration and setting of operating elements and functions.
