Patent ID: 7789348

Claim:
A system for verifying the operation of a railroad gate, said system comprising: a tilt device for measuring a tilt of the railroad gate; a controller coupled to said tilt device, said controller selectively operable in a calibration mode and a monitoring mode, such that when said controller is in the calibration mode, said controller measures a predetermined tilt of the railroad gate, and when said controller is in the monitoring mode, said controller measures a current tilt of the railroad gate to determine deviations between the current tilt and the predetermined tilt; and a compass that measures an angular direction of the railroad gate, said controller coupled to said compass, such that when said controller is in the calibration mode, said controller measures a predetermined direction of the railroad gate, and when said controller is in the monitoring mode, said controller measures a current direction of the railroad gate to determine deviations between the current direction and the predetermined direction.
