A control method for ice and snow melting electric heating system

Abstract

The invention discloses a control method of an ice- and snow-melting electrical heating system. The control method comprises the following construction steps of (1) arranging according to horizontal telescopic gaps of a road surface and a bridge surface, and dividing the road surface and the bridge surface into a plurality of heating regions, wherein the distance among the horizontal telescopic gaps is d, and the value range of the d is 8-12 meters; (2) arranging a plurality of electromagnetic heating units in each heating region in a rectangular array way, wherein the line numbers of the electromagnetic heating units are 1, 2 until M, the row numbers of the electromagnetic heating units are 1, 2 until N, the line number is perpendicular to a travelling direction and is numbered accordingto a sequence from left to right and small to large, the row number is numbered according to a sequence from small to large along the travelling direction, the electromagnetic heating system is provided with S electromagnetic heating units, and S is equal to M by N; and (3) allowing that each electromagnetic heating unit comprises a first electromagnetic heating device, a second electromagnetic heating device and a third electromagnetic heating device which are arranged in a triangular shape. The control method of the ice- and snow-melting electrical heating system can be favorably applied under various conditions, and a road is enabled to be safe and smooth.

Description

technical field [0001] The invention relates to the technical field of ice and snow melting heating, in particular to a control method of an ice and snow melting electric heating system. Background technique [0002] In snow disaster or freezing areas, roads, airport roads, and bridges often experience snow and freezing. At the same time, the incidence of vehicle accidents in special sections such as large longitudinal slopes, bridge ramps, and turns is also on the rise, seriously affecting the normal life of residents. travel, and even cause life-threatening. Therefore, the research on road melting ice and snow is of great significance to people's normal life and property safety. At present, the common road snow melting methods mainly include the following types: artificial deicing and snow removal, mechanical deicing and snow removal, snow melting agent deicing and snow removal, energy conversion ice and snow melting pavement, etc. [0003] Energy conversion ice and snow...
