Intelligent Temperature Control for the Idea and Design of Bridge

摘要

It is cold winter in China, the overlays of road and bridge are easy icing, the cold weather in south China last nearly one month, the north longer. Icy crashes and highway close to bring the huge social influence and economic losses, it is necessary to take effective methods to prevent the road icing. However, some of the current methods of deicing anti ice, both advantages and disadvantages, this paper proposes a new method: using the overlay layer steel mesh, change for the steel reinforcement in one direction, to install the steel bridge deck pavement, laying of heating wire in the pipes, heating the bridge, the entire circuit control system take the advantage of automatic control based on temperature. When the deck temperature is less than 2 °C, the temperature control system automatically launch, wires heating, when the deck temperature is higher than 5 °C, the temperature control system automatically disconnect the power, wires stop warming. In this way, it is achievement to temperature control, at the same time, it will not be icing in low temperature, and easy to repair with a fault, to ensure the vehicle safely pass.
