Method for generating operation strategy of fluid heating road snow-melting system

Abstract

The invention provides a method for generating an operation strategy of a fluid heating road snow melting system. The method is used for estimating heat required by road surface snow melting accordingto different snowfall intensities. The method comprises the following steps: step 1, testing a region where the road section is located to obtain snow melting data, including the input heat power when different snow melting effects are generated at different preheating time are included, wherein the snow melting effects refer to the snow-free time ratio of a certain snow melting target, that is,in the snowfall process, the percentage of the time reaching or superior to the target road surface snow-free rate in the total snowfall time serves as an evaluation index; 2, fitting the coupling rule between the snow melting load of the target pavement and the preheating time of the target pavement by adopting the snow melting data to form a fitting curve; and 3, checking the overlapping degreeof the test point and the fitting curve, if the overlapping degree is high, proving that the fitting method is effective, and carrying out numerical analysis according to the coupling rule between thetarget road surface snow melting load and the target road surface preheating time to obtain the heat required by target road surface snow melting.

Description

technical field [0001] The invention relates to the field of road snow melting treatment, in particular to a method for generating an operation strategy of a fluid heating road snow melting system. Background technique [0002] Snow on the road surface will greatly reduce the efficiency of transportation, increase the probability of traffic accidents, and cause serious losses. Moreover, snow is not allowed to freeze on some special-purpose roads, such as airstrips and aprons. Therefore, people have been studying various scientific and reasonable snow and ice removal technologies on the road surface. At present, the commonly used snow melting and ice melting methods at home and abroad include the clearing method and the melting method. The removal method is divided into two types: manual removal method and mechanical removal method; melting method includes chemical melting method and thermal melting snow melting method. The cleaning method has low efficiency, low removal ra...

Problems solved by technology

[0004] However, at present, the fluid heating road snow melting technology is still in its infancy in my country. The snow melting operation strategy studied in the past is only at the theoretical level, and there is no operation strategy for the fluid heating road snow melting system that adapts to different snowfall intensities.
