For us, quality is everything: Quality management, process orientation and strict testing procedures are of the utmost importance not only during the development phase but also a top priority throughout the entire product lifecycle. Your benefits: high reliability and durability in everyday operation.
Collisions of light rail vehicles and streetcars with each other, as well as with individual vehicles, pedestrians, or fixed obstacles such as bumping posts, are continual serious threats to drivers, passengers, and other road users. The resulting repair and breakdown costs are also considerable. There are many causes of collisions: vehicles making illegal left turns, driver impairment e.g. by blinding sunlight, inadequate attention paid by drivers and crossing pedestrians, technical faults, and health-related causes.
According to the German Federal Regulations on the Construction and Operation of Light Rail Transit Systems (BOStrab), drivers are responsible for avoiding collisions when "driving on sight". They must detect obstacles that pose a potential collision threat in good time, identify the situation as dangerous, and then slow the streetcar down in time using the main or emergency brake.
Building on many years of experience in the automotive sector, proximity detection sensors have been adapted for use in streetcars. Collision warning systems have been developed which assist drivers by providing visual and acoustic warnings when a situation is determined to be hazardous. This allows drivers to react more swiftly and ideally avoid the dangerous situation.
The Bosch Engineering collision warning system for rail applications works on the following principle: The integrated camera identifies the rail track, and a radar sensor detects potential collision objects within the path of the vehicle-regardless of weather conditions. A control device merges the data recorded by the camera and radar, and then connects to the electronics system of the streetcar. Depending on the braking distance, the system then issues timely visual and acoustic warnings in multiple warning levels.
Bosch is one of the technology development leaders and ranks among the companies with the highest number of patent applications. This expertise is reflected in the development of rail applications that ensure your competitive edge.
The obsolescence of electronics on the one hand and ensuring the availability of electronic components on the other hand are major challenges for the rail industry. We can help you solve the obsolescence issue: Owing to the large number of items produced for automobile applications, we are in a position to form long-term agreements with relevant suppliers. This way we make sure that the electronic parts required for your components will be in supply for several decades.
Asset Monitoring for Rail Applications (AMRA) from Bosch Engineering stands for an intelligent system solution for fleet management in railway freight transport. From a single source, you obtain the collection of rail freight car data, the further processing and preparation of this data, as well as a clear illustration with the help of web applications. Our solution enables you to improve the efficiency of your fleet management and helps you to reduce the costs of maintenance, and increase the quality of transport. Functionalities which can be flexibly com-
bined, and the ability to connect to sensors and IT systems, guarantee long-term investment.
How AMRA works:
The telematics hardware is equipped with a GPS module, a GSM antenna, acceleration sensors, and powerful batteries. Fitted to the rail freight car, the AMRA module retrieves position and status information:
The connected sensors monitor and also record vibrations with a location and time stamp, as well as other vehicle and freight parameters. The high-performance processor installed in the module enables immediate processing of the collected data, and therefore rapid implementation of notifications triggered by the occurrence of specific events. The data is transmitted to a server via the cellular phone network (GSM) and made available in a portal, which can be directly accessed using a web application.
Based on well-known standards for applications in the area of the “Internet of Things”, we offer cost-optimized and efficient data transfer. Furthermore, the multi-client capability of the portal enables individual data access rights for the different players in the logistics chain and maintenance. The many years of experience of Bosch in the field of data storage and the operation of global networks guarantee long-term data availability and a high level of data security.
