Vehicle Detection with Classification and Speed Measurement

SW2224 DETECTOR Vehicle Detection with Classification and Speed Measurement

The SW2224 loop detector was specifically designed for vehicle detection with classification and speed measurement.

The SW2224 is a classification detector, operating with two induction loops per lane, in accordance with ASTRA*-SWISS specification.

Based on the proven and tested MC2024 / CD9054, the usages of powerful 32-Bit controllers allow the improvement of all features such as classification accuracy, power consumption, as well as the function range.

The SW2224 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.

The detector can provide the following single-vehicle data via the RS232 service interface and the RS485 data interface:
