103 results about "Line level" patented technology

Line level is the specified strength of an audio signal used to transmit analog sound between audio components such as CD and DVD players, television sets, audio amplifiers, and mixing consoles. Line level sits between other levels of audio signals. There are weaker signals such as those from microphones (Mic Level/Microphone Level) and instrument pickups (Instrument Level), and stronger signals, such as those used to drive headphones and loudspeakers (Speaker Level). The "strength" of these various signals does not necessarily refer to the output voltage of the source device; it also depends on its output impedance and output power capability.

Network-level power dispatching system for urban rail transit lines

The invention discloses a network-level power dispatching system for urban rail transit lines. The system realizes the hierarchical and hierarchical control and emergency treatment on an urban rail transit power supply system by wire network-level power dispatching of an urban rail transit wire network management and control center and line-level power dispatching of a line control center based onthe adoption of a wire network dispatching-line control integrated framework. The cooperative management and control of line network electronic speed controller and line electronic speed controller are realized by adopting a whole line network power dispatching order and line power supply operation order system. A whole line network power supply system real-time power flow calculation system is adopted. An IEC-61970 standard public information model is taken as a basis. An urban rail transit special power supply equipment model is expanded. The power supply system alternating current and direct current hybrid power flow calculation is carried out. The safety check and system optimization scheduling are carried out on an urban rail transit overall power supply network. According to the invention, the management benefit of cooperative power dispatching of each line in the urban rail transit network environment is improved.
