NAVIGATIONAL AID WARNING SYSTEM

摘要

The present invention relates to a device for scanning a plurality of sensor units. The device is comprised of at least one remote data acquisition unit which sequentially scans a plurality of sensor units and which stores data corresponding to the stress measured and the location of the sensor unit measuring the stress. A master control unit is provided for receiving address and stress data from the at least one remote data acquisition unit and comparing the magnitude of the stress with respect to predetermined stress values. A display unit is provided which illustrates the relative magnitude of stress measured with the above mentioned predetermined stress values.
