BS Husky
Software

Open, modular and scalable SCADA software especially customized for control and management of tunnel equipment, but due to its architecture it can be used in other fields such as: transportation, oil/gas industry, energy, utilities, object control etc.
Two main components of BS Husky Software which control the entire system are:

Software core in TMCC (central server)

Software core is a central server which is located in TMCC. It has constant communication with local servers with which it exchanges information. This is the server that controls all local servers and all equipment.

Local servers

Local servers are located in front of and in the back of the tunnel and they control all system in the tunnel as well as nearby signs in front and in the back of the tunnel. It is important to emphasize that servers are placed in pairs to act as a back-up to each other (Hot redundancy). They are usually located in trafo-station (one on each side of the tunnel).

In case of central server failure in TMCC, local servers remain in full operation.

ELEMENT SCHEME

  • 1. TMCC
  • 2. Two-way communication
  • 3. Server
  • 4. Two-way communication
Each individual server controls all elements in a tunnel and in case of its failure the pair server will automatically take over all functions. Some systems are controlled directly through local servers (signs, fire alarm, video system, telephone call system, traffic counters), and some systems are operated by local servers via PLCs (PLC is a device which communicates with end devices which are not controllable directly from the server such as ventilators, lighting, barriers, traffic lights, height detectors, trafo-stations etc.).
