Then repeat step 1；
Step 3, continuous heating overpass road surface, until when overpass ice and snow on road surfaces is with a thickness of 0 and overpass road surface
When the temperature that temperature is higher than snow-broth on 0 DEG C and overpass road surface is higher than 0 DEG C, stops heating overpass road surface, repeat step
1。
9. control method as claimed in claim 8 further includes in step 1 the step for choosing a temperature value T as preset value
Suddenly, the temperature value T is higher than 0 DEG C；In step 2, when the temperature on overpass road surface is lower than T and overpass ice and snow on road surfaces
When thickness is greater than 0, or when overpass ice and snow on road surfaces thickness is greater than 0, or when the temperature on overpass road surface is lower than 0 DEG C,
Or when the temperature of snow-broth on overpass road surface is lower than 0 DEG C, overpass road surface is heated, otherwise repeatedly step 1.
10. control method as claimed in claim 9, when the temperature on overpass road surface is lower than T, in the step 1 and step
It is further comprising the steps of between rapid 2:
It is strong according to overpass scene atmospheric temperature and humidity information, wind direction and wind speed information, atmospheric pressure information, solar radiation
Spend information and precipitation information analysis current weather trend, the Snow Thickness L and product that prediction overpass road surface will will appear
Snow thickness reaches t the time required to L1, time t needed for calculating the accumulated snow melted with a thickness of L2, compare t1And t2Between size close
System；
Work as t1Less than or equal to t2When, overpass road surface is heated, according to current weather trend real-time update t1And t2, continuous heating people
Row overline bridge road surface, until t1Greater than t2；
Work as t1Greater than t2When, execute the step 2.
