Remote ramp control system

Abstract

The invention discloses a remote ramp control system which comprises a ramp device, a local ramp control system and a remote server. A main body of the ramp device is a portal frame. Symmetrical U-shaped slide grooves are arranged in the inner sides of two support feet of the portal frame. A galvanized tube is horizontally arranged between the U-shaped slide grooves. The galvanized tube is connected with a height limiting rod through chains under two ends of the galvanized tube. A motor control box is arranged at one end of a cross beam of the portal frame. Opposite penetrating holes are formed in one end, close to the motor control box, of the galvanized tube, and are in breakover with the height limiting rod through a metal hose. The local ramp control system comprises a microcomputer controller, an embedded network controller, a limiting device and an alarm device. The microcomputer controller and the embedded network controller are arranged in a weak current control box and are connected with the motor control box through soft plastic copper core lines. The other end of the motor control box is respectively connected with the limiting device and the alarm device. The remote server is connected with the local ramp control system in a remote mode through an optical network. The remote ramp control system is mainly used for carrying out remote control on height of the height limiting rods at entrance ramps of elevated roads in urban areas.
