The beneficial effect of the utility model: the utility model discloses can be after the idle running trouble appear in the locomotive, with this device of speed signal acquisition input of locomotive, the device is to the analysis of comparing of all rate signals of locomotive, shows each rate signal of locomotive to judge the speed passageway of trouble, can also find the emergence of locomotive idle running trouble simultaneously according to the information convenient and fast ground that the device shows on a certain speed passageway.
Description
Technical field
The utility model relates to pick-up unit, specifically, relates to a kind of railway locomotive wheel slip fault auxiliary detection device.
Background technology
Current; locomotive is provided with speed pickup on each axle; when the rotating shaft of train wheel drives photoelectric sensor to rotate; locomotive speed is converted to f=n × p/60(p for often to turn umber of pulse by sensor; n is locomotive axle rotating speed: rev/min) square-wave pulse signal; this square-wave signal by RVVP pvc sheath shielded cable into the car, then is sent into electronic housing locomotive is carried out to Characteristics Control and slide system, anti-ly slides protecting control.If wherein electric link breaks down; rate signal Transmission; cause the action of locomotive slide system system protection; the fluctuation of failure screen display " idle running ", traction motor current, the automatic stucco of locomotive, now do not dally between wheel track, is referred to as " false idle running " in scene; when after appearance " false idle running "; because locomotive traction electric current fluctuates widely, there is impulsion in train, is unfavorable for steady manipulation.
Current Electronic locomotive switch board is without the Presentation Function of rate signal, driver driving room only shows a rate signal (the only rate signal of display 1-2 root axle, do not show all rate signals), because fault place is very hidden after appearance DRY RUN fault, service technician only has first judge it is certain shaft speed signal fault, locomotive DRY RUN fault could be processed, so DRY RUN fault is searched very difficult at the scene, can only detect one by one locomotive each rate signal passage multimeter with car or simulation locomotive operation, not only efficiency is low but also inaccurate, there is erroneous judgement may.
So, develop and a kind ofly can show locomotive speed signal in real time and detect the device of locomotive failure speed channels, just become the problem that insider needs solution badly.
Utility model content
For the above-mentioned technical matters in correlation technique, the utility model proposes a kind of railway locomotive wheel slip fault auxiliary detection device, locomotive speed signal can be shown in real time and detect locomotive failure speed channels.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of railway locomotive wheel slip fault auxiliary detection device, comprise message handler, rate signal collector, data-set VI, information display, power supply, wherein, described rate signal collector, data-set VI, information display, power supply are all connected with described message handler.
Further, described rate signal collector is provided with six road rate signal ends.
The beneficial effects of the utility model: the utility model can after DRY RUN fault appears in locomotive, by this device of rate signal Gather and input of locomotive, device compares to all rate signals of locomotive, the rate signal of each axle of display locomotive, and the speed channels of failure judgement, locomotive wheel spin fault can also be found quickly and easily to occur on a certain speed channels according to the information of device display simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the railway locomotive wheel slip fault auxiliary detection device structural representation according to the utility model embodiment.
In figure:
1, message handler; 2, rate signal collector; 3, data-set VI; 4, information display; 5, power supply.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection.
As shown in Figure 1, a kind of railway locomotive wheel slip fault auxiliary detection device according to the utility model embodiment, comprise message handler 1, rate signal collector 2, data-set VI 3, information display 4, power supply 5, wherein, described rate signal collector 2, data-set VI 3, information display 4, power supply 5 are all connected with described message handler 1.
In one embodiment, described rate signal collector 2 is provided with six road rate signal ends.
Conveniently understand technique scheme of the present utility model, below by way of in concrete use-pattern, technique scheme of the present utility model is described in detail.
When specifically using, according to railway locomotive wheel slip fault auxiliary detection device described in the utility model, there are six road rate signal acquisition functions, six road rate signals can be gathered simultaneously, meet current railway locomotive wheel slip troubleshooting requirement, and, Negotiation speed signal picker completes, be provided with six road rate signal collections altogether, each joint locomotive of current railway locomotive is divided into six axles and four axles, every axle is provided with a road speed pickup and sends into Electronic locomotive control system participation slip control, the rate signal collection of each slide system control system is no more than at most six tunnels, so establish six road rate signal acquisition channels can meet the judgement needs of railway locomotive wheel slip fault, six road rate signals can be shown in real time simultaneously, each axle speed of detection of dynamic locomotive, user of service can the ruuning situation of each axle of intuitive judgment locomotive, simultaneously, each shaft speed signal after rate signal collector Collect conversion processes at message handler by it, the square-wave pulse signal that speed pickup transmission comes is transformed to the voltage signal be directly proportional to its frequency, ratio is 100Km/h correspondence-5.0V, the wheel footpath data inputted with data-set VI carry out comparing calculation, calculate the real time data of each axle speed, and on information display, the rate signal collected is carried out list and show in real time, can automatic decision fault speed channels, and alarm indication and record keep, process at message handler from each shaft speed signal after speed signal picker Collect conversion, when each channel speed signal errors is more than 3Km/h, judge faulty channel, and display alarm on information display, described power supply is intra-locomotive 15V power supply, and this power supply comprises device power supply (DPS) operating switch, cut-offfing of controllable device power supply.
