Wireless multiplex data transmission system

A through is at least two local data pickoffs (e.g., vehicle and data pickoff or NVH sensor) is communication channel wireless data transmission method and device, comprising a primary data - processing function unit and a wherein the data data - processing function unit (e.g PC.). The system of the frequency or or the packet switching base providing communication channel by a blocking, symmetrically arranged in parallel to the local data pickoff's a switching data transmission demand matching capacity of wherein a sub-board is released, a single channel of transmission of which the data. A particularly actual application source automatic in three-dimensional at NVH sensor the noise vibration grating analysis of wireless transmission data, and vibration source space accurately and position of vehicle at analytical learning.
