Abstract: An intelligent vehicle capturing apparatus for a high-pier bridge includes: a double-layer metal protective net, support unit and actuation unit connected thereto. The protective net mounts to a high-pier bridge backside through the support unit. The actuation unit includes a hydraulic link mechanism connected to one end of the protective net. The hydraulic link mechanism unwinds the protective net to capture a vehicle. The apparatus stops a vehicle rushing off a high-pier bridge. Upon completion, a hydraulic system drives a third hydraulic cylinder in a support rod on the high-pier bridge backside driving a rolling shaft rotating, winding and placing a protective net on the high-pier bridge backside. The apparatus has a simple structure, is practical and easily used, useful on hazardous high-pier bridges protecting vehicle passengers and avoiding traffic accidents resulting from vehicles rushing out of the high-pier bridges.

Abstract: A magnetic tag sensor includes a cylinder and threaded pipe embedded therein and simulates a magnetic dipole; two threaded pipe wiring interfaces being connected to first and second cables, running through a cylinder upper cross-section outer wall and extending out of the cylinder; the cylinder is sleeved on a guide rail and at a junction between a riverbed and water; an guide rail end inserts into the riverbed, a water sealing box is mounted on a top of the guide rail, a power supply module, a relay and a load arranged inside the water sealing box, the first cable connected to a positive pole of the power supply module, and the second cable connected to a negative pole through the relay and load connected in series; and the threaded pipe in the wall of the cylinder moves up and down with the riverbed to generate a magnetic field signal.
