If no electric locomotive passes through in 1h, environmental parameter such as wind speed, temperature, the liquid around icing contact net are obtained
State water content etc., the icing for calculating acquisition icing contact net using Makkonen icing prediction models according to these environmental parameters are strong
M is spent, and obtains the rate of traffic flow in icing contact net place section.If rate of traffic flow be more than rate of traffic flow and M be no more than it is default most
Big tolerance icing intensity sends the sliding deicing instruction of heat.
If being appreciated that, icing intensity is smaller, shows that contact line icing growth rate is slow, in addition the section rate of traffic flow
Greatly, train process, the sliding contact of pantograph and contact line, friction energy constantly wipe most of icing, therefore, such case off
Under without additional input deicing measure, continue using the sliding deicing of heat.And ice-shedding amplitude caused by the sliding deicing of heat is smaller, energy
Ensure electric locomotive safety.
Step S234, if it is more than that deicing is pre- that practical icing weight, which is more than with reference to the absolute value of icing weight and the difference of the two,
If value, the ice-shedding situation for analyzing different de-icing methods is calculated, and corresponding de-icing method is chosen according to ice-shedding situation.
For example, if Δ M is more than MiAnd Δ M and MiThe absolute value of difference be more thanM0, surface needs additionally to put at this time

Tj、Ei, λ and Δ M calculate what icing contact net was deiced under SVG ice-melting modes and in the case where deicing mode is vibrated in mechanical shock
Ice-shedding duration tsvgAnd tmac。
Wherein, Ej130GPa, T can be takenj13kN, E can be takeniIt can take 0.1e11GPa, λ that can take 0.3.
tsvgAnd tmacShow under different deicing modes contact line deices vibration duration, if contact line is also carrying out
Vibration, be open to traffic at this time can cause mechanical damage to contact line and pantograph, therefore, it is necessary to etc. contact lines ice-shedding stop
It can be open to traffic.Further, intelligent deicer obtains the most short required duration t that electric locomotive reaches icing contact linem, and will
tsvgAnd tmacRespectively with tmIt is compared.
There are four types of situations for comparison result：
(1)tsvgAnd tmacNo more than tm, send and deicing carried out using SVG ice-melting modes or is removed using mechanical shock vibration
Ice mode carries out the instruction of deicing.In this case, the ice jump time that two kinds of deicing modes generate is both less than train arrival
Before required time, i.e. train reach, ice jump is over.Therefore SVG ice-melts or mechanical shock can be selected to vibrate in deicing
One way in which carry out deicing.
(2)tsvgNo more than tmAnd tmacMore than tm, send the instruction that deicing is carried out using SVG ice-melting modes.It is appreciated that
In this case, the ice-shedding time that mechanical shock vibration deicing generates is more than train time to go, should not be made
Deicing is vibrated with mechanical shock.
(3)tsvgMore than tmAnd tmacNo more than tm, send the instruction that deicing is carried out using mechanical shock vibration deicing mode.
It is appreciated that in this case, the ice-shedding time that SVG ice-melts generate is more than train time to go, should not be made
With SVG ice-melts.
(4)tsvgAnd tmacAbove tm, send the hint instructions for stopping the operation of icing contact line.It is appreciated that this
In the case of, the ice jump duration caused by two kinds of de-icing methods is above train time to go, and intelligent deicer obtains
Smaller ice under two kinds of deicing modes jumps the duration, for example, the ice jump duration using SVG ice-melts is smaller, it will smaller ice
Jump the ice-shedding duration the shortest duration.
Further, intelligent deicer is according to most short ice-shedding duration, tmWith the speed of service of electric locomotive
It calculates and obtains the stand-by period, and waiting instruction and the stand-by period that icing contact net needs stoppage in transit deicing are sent to electric locomotive.
Electric locomotive is obtaining waiting instruction and after the stand-by period, can execute corresponding operating.So set, being avoided that
Electric locomotive during contact line ice-shedding by contact line, and then the secondary disaster for avoiding deicing from bringing.
