Control, information and security system
The control, information and security system ( LISI ) is a computer-aided operations control system (RBL) that the Berliner Verkehrsbetriebe (BVG) uses to carry out underground operations. The system was designed in the 1990s and supplied by Siemens Verkehrstechnik in Braunschweig and the then Alcatel in Stuttgart , which has since been transferred to the Thales Group .
system
LISI consists of the following components:
- Train - identification system (CIS)
- Train monitoring (ZLÜ)
- Remote control of the signal boxes (FStw)
- Train steering (ZLK)
All BVG underground lines ( small and large profile ) are equipped. For this purpose, ZIS readers were installed at all station entrances and exits as well as all switches .
All underground vehicles are provided with electronically readable identifiers (mobile data storage device MDS) for the train identification system. In the case of double railcars , this is located under the coupling between the two cars . Trains the H Series carry three MDS.
The control system is operated from a control center on the BVG premises of the Friedrichsfelde workshop at the Tierpark underground station . The control system combined numerous decentralized signal boxes along the underground lines to form a central signal box .
LISI supplies, among other things, the data on the locations of the vehicles , which the dynamic passenger information DAISY processes for the display texts on the platforms .
