Each BUES 2000 level crossing has a diagnosis module that is connected with the safe system core on the one hand in a reaction-free manner and on the other hand via an interface. For diagnosis the CAN telegrams, which transmits on system buses, are read and can be displayed optionally using a graphic or text-based interface.
A Windows-based diagnosis program is installed on the local PC. This decodes and stores the BUES 2000 telegrams received. With the aid of appropriate data management functionality, faults and disruptions are prepared and stored for the service and maintenance personnel.
The graphic interface of the diagnostic system provides a topographically illustrated overview in an unique global map with function, module and field element statuses of the respective full system. Alongside the display of active condition, change like opening and closing of barriers or activation of train detection system, faulty elements are visualised clearly as well as in real time. Furthermore, they are stored in a circulating buffer in plain text whereby they are given a time stamp. This means the latest 1000 events can be called up in plain text as window display. With the aid of menus the stored data can also be displayed and evaluated. There are special analysis tools available as well as the online assistant for analysis.
Each level crossing can be connected to the diagnostic centre via a leased-line modem.
Then these data, which are stored in the local diagnosis systems, can be transferred to the diagnostic centre. Data transmission is based on international standards and protocols such as TCP/IP.
