Title:
SOUND GUIDANCE NETWORK SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/050771
Kind Code:
A1
Abstract:
[Problem] To provide a system whereby, with respect to a complex network-shaped path, a signal sound is repeatedly emitted, a notification of a path made to a pedestrian, and a notification and a safe guidance made of an overall direction of a walking range, as well as of a location relation between a hazardous site and the pedestrian. [Solution] With respect to a plurality of guidance parts and all paths in a signal propagation zone which connect same, signal wiring which bundles four wires wherethrough a four-phase signal passes and a common line is installed along a path. In each guidance part, a deviation of an approximately constant distance d is applied to the wires of each phase and a speaker is periodically installed. A signal current whereto a delay of a prescribed time t is applied for each phase is sent from a control device into the wires of each phase of the signal line. Using a bird sound, a guidance signal sound wave results as if a bird is flying along a path of speakers (A, B, C, D, etc.), and it is possible in a network-shaped overall guide path to guide along a complex path by forming a guide signal wave.
