Lift-type height limiting frame intelligent lifting and height-limiting control method based on geomagnetic detection
The invention relates to a lift-type height limiting frame intelligent lifting and height-limiting control method based on geomagnetic detection. The method comprises the following steps: by utilizing two rows of geomagnetic sensors, obtaining a real-time driving speed and a vehicle length of a vehicle passing through the geomagnetic sensors; judging a type of the vehicle according to the vehicle length, judging whether the type of the vehicle belongs to restricted vehicle types according to the vehicle type of the vehicle, and entering into the next step if the type of the vehicle belongs to the restricted vehicle types; calculating a time T1 needed by the vehicle to reach a lift type height limiting frame from the geomagnetic sensor close to a position of a ramp entrance and a time T2 needed by a lifting rod of the lift type height limiting frame to descend to a restricted height; if T1 is greater than or equal to T2, controlling the lifting rod of the lift type height limiting frame to descend, and sending an early-warning signal; and, if T1 is less than T2, controlling the lifting rod of the lift type height limiting frame to make no action, and returning to the second step. The method improves safety of the lift-type height limiting frame in the lifting process, prevents the vehicle from crashing into the lifting rod of the lift type height limiting frame, is more intelligent, and reduces management personnel's work intensity.
