Real-time position tracking for buses

Symeo, a provider of solutions for position tracking, will exhibit its products at InnoTrans in Berlin, Germany, from 18 to 21 September 2012. The company will have its new wireless solutions for position tracking, distance measurement and collision warning on display in Hall 2.1 at Booth 202. The SPU (Symeo Positioning Unit) enables transit companies to better manage their fleets while increasing operational safety in the process.

The SPU is a positioning device that can be permanently mounted on the roof of a vehicle. The compact device integrates the positioning system and all antennas into one weatherproof casing. The SPU is capable of capturing positioning and navigation information for buses, locomotives, railcars and other vehicles in real time using LPR or GPS. There are more than 700 buses in Hamburg and more than 400 in Düsseldorf that are currently equipped with these systems. The efficiency of the bus depot management system can be substantially increased when enhanced by the precise positioning of all fleet vehicles.

Symeo will also introduce its Symeo Telemetry Unit (STU) for vehicle management at this year’s InnoTrans. This sturdy device is suitable for installation on railcars. In addition to determining vehicle positions, it enables the operator to capture vehicle data such as fuel/electricity consumption, miles driven and vehicle status data. The STU can be configured flexibly, and it can capture signals using a wide variety of methods (analogue, digital or via bus systems). The data can also be exported using data interfaces (RS232, TCP/IP, RS422), which can be specifically tailored to the customer’s needs.

Laser substitute
The extremely precise DR-1D radar measuring systems for distance measurement are much more durable than traditional laser systems, because these Symeo systems are not affected by dirt and adverse weather conditions. Typically, these systems can be used for distance measurement between cranes and railway vehicles such as subways or trains. When combined with a simple 20-cm reflector (in diameter), it is possible to even implement movement controls over larger distances based on the DR-1D radio system as a more robust alternative to traditional laser based light-barrier systems.
