In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to present invention enforcement
The accompanying drawing to be used needed for example or description of the prior art is made one and is briefly introduced, it should be apparent that, drawings discussed below is this
Some embodiments of invention, for one of ordinary skill in the art, on the premise of not paying creative work, may be used also
To obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is the derailing Cleaning Principle schematic diagram of guide wheel derailing detection method of the present invention.
Specific embodiment
To make purpose, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
The a part of embodiment of the present invention, rather than the embodiment of whole.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Guide rail electric car has two power EEF bogies and multiple non-powered EEF bogies, when positive head car M1 is used, guide rail electric car
Run forward, when anti-head car M2 is used, guide rail electric car runs backward, realizes the way traffic of guide rail electric car.In the present embodiment,
Implement the derailing inspection of identical guide wheel in the guide wheel of the power EEF bogie of the guide wheel and anti-head car M2 of the power EEF bogie of positive head car M1
Survey method.The guide wheel derailing detection method of the power EEF bogie of positive head car M1 introduced below.
As shown in figure 1, the present embodiment is related to a kind of method of guide wheel derailing detection, comprise the steps：（1）Walk along electric current
To being sequentially connected in power supply, resistance R, power EEF bogie second in the grounding device EB1 of the first guide wheel, guide rail and power EEF bogie
The grounding device EB2 of guide wheel constitutes level detection loop；Led by PLC control unit collection resistance R and power EEF bogie first
Level between the grounding device EB1 of wheel at junction point；When the level for collecting is low level, control guide wheel is continued to run with；
When the level for collecting is high level, control guide wheel stops, and wherein high level is less than intended threshold level, and the present embodiment makes a reservation for
Threshold value can determine according to the difference of supply voltage and line loss voltage.
Specifically, in the present embodiment, power supply is 24V DC sources, wherein the minus earth of the power supply.PLC controls are single
Level between unit collection resistance R and grounding device EB1 at junction point, when normally being run due to train, grounding device EB1, EB2
It is grounded with guide rail, electric current flows out from positive source, sequentially passes through resistance, grounding device EB1, guide rail, grounding device EB2 and flow to
Power cathode（I.e.）The low level during level of now PLC control unit collection, low level is ground in the present embodiment；When train goes out
When now derailing, contact device EB1, EB2 and guide rail depart from, and level detection loop disconnects, and PLC control unit collects high level letter
Number；Thus according to the level signal of PLC control unit collection, guide wheel normally operation or derailing are may indicate that, such that it is able to control
Guide wheel is continued to run with or stopped.The detection method is simply easily achieved, and reliability and real-time are higher, timely will can lead
Wheel is sent to electric car control system with the state of guide rail contact, realizes the advance or braking of guide rail electric car, strengthens guide rail electric car
Derailing performance.
Such as Fig. 1, when normal, the secondary power supply SIV on electric car can be for level detection loop power supply and for 24V unidirectional currents
Charge in source；When SIV breaks down or disconnects, 24V power supplys can access loop for level detection loop power supply.
In order to prevent guide rail electric car from the situation of guide wheel derailing wrong report, PLC controls are caused through guide rail seam crossing or other situations
Delay circuit is provided with unit processed, when PLC control unit collects the height between resistance R and grounding device EB1 at junction point
Time delay is for a period of time after level signal, it is ensured that after receiving the continuous high level signal, can just judge that train occurs derailing existing
As.After it there is derailment occurring, PLC control unit sends the warning message of derailing, while triggering the brake hard of electric car, prevents
Only electric car is overturned, and reduces the person and property loss.The warning message may be displayed on the display with PLC control unit communication connection
On screen, the display screen can be arranged in drivers' cab, and by the information checked on the display screen train derailing can be in time obtained
Information；Control signal can also be sent according to the warning message PLC control unit, be sent control signals to single with PLC controls
On the alarm of unit's communication connection, make alarm send alarm sound, point out staff's train that derailment occurring occurs, in time
Take brake measure, reduce risk.
As shown in figure 1, in order to obtain train status simultaneously at positive head car M1 and anti-head car M2, carrying out at anti-head car M2
Similar with positive head car M1 guide wheel derailing detection method, and by the resistance R and anti-head in level detection loop in positive head car M1
Resistance R in car M1 in level detection loop is connected so that the PLC control unit in positive head car M1 receives guide wheel with guide rail
While contact condition, the PLC control unit in anti-head car M2 also receives the contact condition of guide wheel and guide rail, and both are superfluous each other
It is remaining, improve the reliability of derailing detection.
The method of the present embodiment guide wheel derailing detection, the first guide wheel in PLC control unit collection resistance R and power EEF bogie
Level between grounding device EB1 at junction point, when the level that PLC control unit is collected is low level, shows that guide wheel leads to
Cross its grounding device EB1, EB2 normally to contact with guide rail, when the level that PLC control unit is collected is high level, show to lead
Wheel is disconnected by its grounding device EB1, EB2 and guide rail, and the detection method is simply easily realized, is easy to safeguard；Can by the signal of telecommunication
In time the state of guide wheel and guide rail contact is sent to into electric car control system, realize the advance or braking of electric car, reliability and
Real-time is high, enhances guide wheel derailing performance, improves the safety of car load.
Finally it should be noted that：Above example only to illustrate technical scheme, rather than a limitation；Although
The present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
To modify to the technical scheme described in foregoing embodiments, or equivalent is carried out to which part technical characteristic；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
