step S21, the weight and image information of the ice-coated contact line are obtained in real time.
In this example, the icing contact line has a weight of MtThe image information includes an axial view and a front view of the ice coating contact line. It can be understood that MtIncluding the weight of the contact wire itself and the weight of the ice. The axial view and the front view can improve the accuracy of the calculation of the ice coating volume.
Step S22, obtaining icing reference density and weight of an icing contact line when the icing is not coated, and calculating according to the image information and the icing reference density to obtain reference icing weight; and calculating to obtain the actual icing weight according to the weight of the icing contact line when the icing is not coated and the weight of the icing contact line.
In the present embodiment, the icing reference density is ρiThe weight of the ice-coated contact line is M when the ice is not coated0。
, the intelligent deicing device obtains the calculated radius R of the contact line when the contact line is not coated with ice0Obtaining the icing radius R of the icing contact line according to the axial view and the front viewiceThen according to R0And RiceCalculating to obtain the ice coating sectional area SiceWherein, in the step (A),
Figure BDA0001625438810000071
, the intelligent deicing device obtains the span l of icing contact line according tol and SiceCalculating to obtain the icing volume ViceWherein V isice＝l·Sice step forward, the intelligent de-icing apparatus is according to ρiAnd SiceCalculating to obtain reference icing weight MiWherein M isi＝ρi·Vice。
In the present embodiment, ρiCan be 900kg/m3。
It can be understood that the intelligent de-icing device can refer to the icing weight M according to the image informationiThe icing condition can be analyzed from the image perspective.
In order to more accurately analyze the icing condition, the method calculates the reference icing weight M according to the image informationiAnd comparing the actual icing weight delta M calculated according to the weight information to obtain a more accurate result.
For example, calculating the actual icing weight Δ M from the weight information may be implemented by: according to M0And MtCalculating to obtain the actual icing weight delta M, wherein the delta M is Mt-M0。
And step S23, comparing the actual icing weight with the reference icing weight to obtain a comparison result, and sending a corresponding deicing instruction according to the comparison result.
There is a deviation between the reference icing weight obtained from the image information as a calculation and the reference icing weight obtained from the weight information as a calculation, and deicing measures are taken without comparative analysis of the two, , which may increase additional economic investment, or secondary disaster may be caused by a long deicing jump duration if the deicing measures are not properly selected.
Referring to fig. 3, in the present embodiment, steps S231, S232, and S233 are used to list implementations of step S23.
Step S231 calculates a difference between the actual icing weight and the reference icing weight.
Step S232, if the actual icing weight is less than the reference icing weight and the absolute value of the difference value between the reference icing weight and the reference icing weight is greater than the critical preset value of the icing type, calculating to obtain the actual icing density according to the actual icing weight, analyzing the actual icing density, and if the actual icing density is less than 0.1g/m3And judging the icing type to be dry growth icing.
In the present embodiment, the critical preset value of the ice coating type may beMi
If Δ M is less than MiAnd Δ M and MiIs greater than
Figure BDA0001625438810000082
MiAnd calculating and obtaining the actual ice coating density rho according to the delta MsTo p rhosAnalysis is carried out if rhos<0.1g/cm3The method comprises the steps of judging whether the icing type is dry-growth icing, wherein the dry-growth icing refers to that supercooled liquid drops are rapidly frozen and completely solidified when being in contact with the surface of a dry contact line, and the formed icing is rime icing or dry snow icing, wherein the dry snow is attached to the surface of the contact line when the wind speed is low enough ( is lower than 2m/s), but the influence caused by the dry snow icing can be ignored because the icing strength is low and the dry snow density is lower than 0.1g/cm3, the adhesive force is small, and the dry snow icing is easy to blow off or automatically slide off, and at the moment, the intelligent deicing device does not send a deicing command.
Step S233, if the actual icing weight is greater than the reference icing weight and the absolute value of the difference between the actual icing weight and the reference icing weight does not exceed the deicing preset value, determining whether the electric locomotive passes through the deicing device within a preset time period, and sending a corresponding deicing command according to the determination result.
In this embodiment, the preset value of deicing may be
Figure BDA0001625438810000083
M0The preset period may be 1 h.
For example, if Δ M is greater than MiAnd Δ M and MiAbsolute value of the difference of (2)M0And judging whether the electric locomotive passes through within 1h or not:
the intelligent deicing device sends a hot slip deicing command if the electric locomotive passes within 1h, wherein the hot slip deicing means that deicing measures are not additionally put into, the electric locomotive directly passes through an icing contact line and is subjected to sliding contact and friction deicing through a pantograph and the contact line of the electric locomotive, and the deicing method is generally applied to an interval with smaller icing quality.
And if no electric locomotive passes within 1h, obtaining environmental parameters around the icing contact net, such as wind speed, temperature, liquid water content and the like, calculating the icing strength M of the icing contact net according to the environmental parameters by adopting a Makkonen icing prediction model, and obtaining the travelling density of the section where the icing contact net is located. And if the driving density is greater than the driving density and M does not exceed the preset maximum tolerance icing intensity, sending a hot slip deicing instruction.
It can be understood that if the icing strength is small, the contact line icing growth speed is low, and the running density in the interval is high, so that a train continuously passes through, most of the icing can be scraped by the sliding contact and friction energy of the pantograph and the contact line, therefore, no extra deicing measures need to be invested in the situation, and the hot sliding deicing is continuously adopted. And the ice-shedding jumping amplitude caused by the hot-slip ice-removing is smaller, so that the electric locomotive can be ensured to safely pass through.
And S234, calculating and analyzing the deicing jump conditions of different deicing methods if the actual icing weight is larger than the reference icing weight and the absolute value of the difference value of the actual icing weight and the reference icing weight exceeds the deicing preset value, and selecting the corresponding deicing method according to the deicing jump conditions.
For example, if Δ M is greater than MiAnd Δ M and MiIs greater than the absolute value of the difference
Figure BDA0001625438810000091
M0Additional deicing measures are then required on the surface. Elastic modulus E of ice-coated contact line obtained by intelligent deicing devicejTension TjIn advance ofModulus of elasticity E for icingi steps further, additional input deicing measures include SVG deicing and mechanical shock vibration deicingj、Tj、EiLambda and delta M respectively calculate the deicing jump duration t of the icing contact net for deicing in the SVG deicing mode and in the mechanical shock vibration deicing modesvgAnd tmac。
In this embodiment, the intelligent deicing device may be implemented in ANSYS simulation software using a finite element analysis method according to Ej、Tj、EiLambda and delta M are used for calculating the deicing jump duration t of the deicing contact net for deicing in the SVG deicing mode and the mechanical shock vibration deicing modesvgAnd tmac。
Wherein E isjCan be 130GPa, TjMay take 13kN, Ei0.1e11GPa and λ 0.3 can be taken.
tsvgAnd tmacIndicating the deicing vibration duration of the contact line under different deicing modes, if the contact line is vibrating, the vehicle can cause mechanical damage to the contact line and the pantograph when the vehicle is started, so that the vehicle can be started only when the deicing jump of the contact line is stopped, and steps are carried out, wherein the intelligent deicing device obtains the shortest required time t for the electric locomotive to reach the icing contact linemAnd will tsvgAnd tmacRespectively with tmA comparison is made.
There are four cases of comparison:
(1)tsvgand tmacAre not more than tmUnder the condition, the ice jump time generated by the two deicing modes is shorter than the time required by the arrival of the train, namely the ice jump is finished before the arrival of the train, so modes in the SVG deicing mode or the mechanical impact vibration deicing mode can be selected for deicing.
(2)tsvgNot exceeding tmAnd t ismacExceeds tmAnd sending an instruction for deicing in an SVG deicing mode.It will be appreciated that in this case, the jump in ice detachment time caused by mechanical shock vibration de-icing exceeds the time required for the train to arrive, and mechanical shock vibration de-icing should not be used.
(3)tsvgExceeds tmAnd t ismacNot exceeding tmAnd sending an instruction for deicing by adopting a mechanical impact vibration deicing mode. It will be appreciated that in this case, the ice-shedding jump time produced by SVG ice-melting exceeds the time required for the train to arrive, and SVG ice-melting should not be used.
(4)tsvgAnd tmacAll exceed tmAnd sending a prompt instruction for stopping the operation of the icing contact line. It can be understood that in this case, the ice jump duration caused by the two deicing methods exceeds the time required by the train to arrive, and the intelligent deicing device obtains the smaller ice jump duration in the two deicing modes, for example, the ice jump duration for deicing by using SVG is smaller, and the smaller ice jump duration is the shortest ice jump duration.
, the intelligent deicing device jumps according to the shortest deicing duration, tmAnd calculating the running speed of the electric locomotive to obtain the waiting time, and sending a waiting instruction and the waiting time that the icing contact net needs to be stopped for deicing to the electric locomotive.
After obtaining the waiting command and the waiting time, the electric locomotive can execute corresponding operations. By the arrangement, the electric locomotive can be prevented from passing through the contact wire during the contact wire deicing jumping, and further secondary disasters caused by deicing are avoided.
It can be understood that the intelligent deicing device can adopt different deicing modes according to specific icing conditions, and can reduce the secondary disasters caused by the economic investment and deicing jumping of deicing.
The intelligent deicing device can modify the ice coating type critical preset value and the deicing preset value according to the obtained modification instruction so as to cope with the ice coating conditions in different environments and different working conditions.
On the basis of the above, as shown in fig. 4, an embodiment of the present invention provides deicing devices 20, where the deicing devices 20 include an acquisition module 21, an initialization module 22, a startup data transmission module 23, and a program data packet transmission module 24.
