E-WIM Weigh-in-Motion System

Description

Explanation:

The E-WIM 400 has been developed for high-speed axle weight measurement and classification for law enforcement applications. High-speed Weigh-in-Motion (WIM) systems play an important role as a pre-alert subsystem in conjunction with low-speed axle weight measurement stations. High-speed WIM systems allow weight measurements without interrupting regular traffic flow. The E-WIM 400 operates using piezoelectric and inductive loop sensors installed in the roadway. Weight measurements are provided for each axle, axle group, and the total vehicle weight.

The E-WIM 400 can operate as either a standalone unit with a warning light or as an integrated system equipped with a personal computer, low-speed axle scale, and high-speed video camera. The E-WIM 400 is designed with new technology, high-speed 32-bit microcontrollers in a 19″ 3U rack form with Euro-sized modules that can be easily replaced. Data can be transmitted up to 1 km via an isolated RS-422 interface and up to 15 meters via an RS-232 interface. The E-WIM 400 can also communicate via the GSM network. – E1318 Recommendations.
