Highway crash barrier monitoring system

摘要

A highway crash barrier (10) includes a collision sensor (46) that detects when a vehicle collides with the crash barrier (10). A transmitter (40) is coupled with the collision sensor (46) to transmit a radio frequency signal to a remote location when this collision sensor (46) detects a collision. This radio frequency signal includes a fault message that is forwarded automatically to a user responsible for maintenance of the crash barrier (10). A camera (42) is controlled in response to the collision sensor (46) to store an image of the crash barrier (10) shortly after the collision. <IMAGE>
