Abstract
A NEED EXISTS TO MONITOR VIBRATION IN HIGHWAY BRIDGES. IT IS DESIRABLE TO MONITOR MANY POINTS ON THE BRIDGE. THE CURRENT PROBLEM IS THAT SENSORS MUST BE WIRED TO A CENTRAL LOCATION. WIRE IS DIFFICULT TO INSTALL AND TO MOVE. THE SOLUTION IS TO COLLECT SENSOR DATA BY RADIO. A SYSTEM EXISTS THAT ELIMINATES WIRE. IT GATHERS SENSOR DATA TO A CENTRAL LOCATION BY RADIO. THE SYSTEM'S UNIQUE FEATURE IS THAT ALL DATA NODES ACT AS RELAYS FOR EACH OTHER. THE FURTHEST DATA NODE FROM THE CENTRAL DOES NOT HAVE TO TRANSMIT DIRECT TO THE CENTRAL. INSTEAD, DATA IS RELAYED FROM NODE TO NODE AND THEN TO CENTRAL. COMMAND INSTRUCTIONSARE PASSED FROM THE CENTRAL TO THE NODES THE SAME WAY. THE TECHNIQUE RESULTS IN COMMON HARDWARE MODULES, LOW POWER, ANDSIMPLE OPERATION. PHASE I WILL DEMONSTRATE OPERATION ON A TEST BRIDGE. INSTALLATION AND OPERATION ARE AUTOMATIC. NODES ARE LOGGED IN AS THEY POWER UP. THE NETWORK LEARNS ASIT OPERATES. IT RECONFIGURES ITSELF TO REACT TO SIGNAL BLOCKAGE. MANY APPLICATIONS ARE POSSIBLE. THE GENERIC APPLICATION IS ANY REQUIREMENT FOR THE MEASUREMENT OF EVENTSOCCURRING AT ONE LOCATION; AND, TABULATION OF THAT EVENT WITH LIKE EVENTS COINCIDENTALLY OCCURRING AT OTHER LOCATIONS.
