The bar bit test device of electrification railway contact net inspection vehicle
Technical field
The utility model relates to a kind of in electrified railway, the bar bit test device of particularly using on the high-speed electric railway Contact Line Detection car.
Background technology
The Contact Line Detection car is the special-use vehicle that is used for the electrification railway contact net parameter testing, is a mobile complex laboratory.Inspection vehicle travels on the electric traction section, is used to detect the geometric position parameter of contact system, comprises stagger, lead height, the intersegmental distance of anchor, line trouble, the lead gradient, the registration arm gradient; Dynamical parameter is as bow net contact pressure, elasticity, bow net impact acceleration, off-line, vehicle dynamic compensation value, running velocity; Electric parameter is as contact system voltage; Ambient temperature and line parameter circuit value as station, interval, mileage, bar position etc., as calculated after the machine analyzing and processing, will occur or potential problem notice maintenance department, provide guidance for the state maintenance of power supply department provides foundation and supervisory management zone to carry out macro-control.
The overhead corresponding contact net for power supplying that is provided with of downline is that the supporting mechanism by contact system sets up and locatees, and wherein electric pole is the pillar of erecting contact net, is main and most important supporting mechanism.The supporting mechanism of other corresponding form is in addition located in this external bridge and tunnel etc.These supporting mechanisms all are the locating points of contact system, can be referred to as electric pole.Always adopt a registration arm (metal bar that about 30mm is thick) on the electric pole, contact system is positioned.On electrification railway contact net, for guaranteeing the abrasion of pantograph bow face evenly, therefore contact wire is forced to be the setting of " it " font, registration arm is also corresponding to distribute to both sides, the one end is fixed on the contact wire, and the other end is separately fixed at along on the electric pole of electrified railway line both sides serial arrangement and number consecutively.The bar position is the position of electric pole, the numbering of each electric pole at affiliated station or the interval all be unique, therefore, always with basic coordinates such as station or interval, electric pole numbering etc. as the inspection vehicle test data.In testing process, the position of the electric pole with particular number of inspection vehicle process is tested in requirement exactly, so that with the data of detection and the operating mode of actual track, strict corresponding as station, interval, electric pole numbering etc., otherwise the error situation that the data that detection obtains will occur fastening one person's story upon another person.
The early stage device that on the electrification railway contact net inspection vehicle, is used for the test rod position, be to be foundation with the original design data bank to railway relevant rod along the line position that is stored in the computing machine, the range pulse mode of combining that obtains with the speed sensor that is cooperated by axletree positions.Name storage respectively and set up circuit information database promptly at first with the numbering of each bar circuit, each station or interval, each electric pole and the information such as distance between the electric pole, and by up-downlink direction.When inspection vehicle brings into operation, operating personal is confirmed the position at its place earlier, as title, up-downlink direction, station or the interval title of circuit, apart from numbering of the nearest the place ahead electric pole of inspection vehicle etc., the database information of corresponding line and direction in calling computing machine, and database data and tested actual field are associated by cooresponding station or interval title, electric pole numbering.Along with the operation of inspection vehicle, distance between cooresponding electric pole and the range pulse calculated distance comparison that obtains from speed sensor, when both were equal, next bar position had been arrived in identification, and so carry out successively the location.Because this test process and principle are not directly to test the position at the actual place of electric pole, but the distance of calculating by range pulse, i.e. the spacing of the two adjacent electric poles of depositing in the data-driven storehouse is inferred out the position of each electric pole successively.So the time is long slightly, causes the cumulative errors of distance easily.Its reason is from speed sensor.Because inspection vehicle is in operational process, all causes the cumulative errors of range pulse easily as slip, serpentine locomotion and the various random vibrations etc. of wheel, thereby influence locating accuracy.Facts have proved that its error amount is generally the dislocation that may have 1 electric pole about 1 kilometer.
For addressing the above problem, present improved inspection vehicle is the equipment that has increased test electric pole steady arm on original basis.Inspection vehicle is when section operation, the electric pole test can be proofreaied and correct in early days with the database combination range pulse location cumulative errors that mode of operation was caused, that is: if range pulse according to two adjacent pole clearances in the data bank the leading or several meters location that lag behind, but in case test the electric pole signal, even if the distance of range pulse and data bank is unequal, also will be unconditionally the new bar position starting point of the electric pole test point of reality as the range pulse counting, thereby can eliminate the accumulation of error, for real correct starting point is provided data bank and cooperating of range pulse.This improvement has had bigger development on the basis of original inspection vehicle, though can eliminate the cumulative errors between two electric poles to a certain extent, but because the unnecessary interference that intersects background of the also wired trouble in top (with the corresponding top of track switch) of inspection vehicle process, anchor section (the thread-changing junction of contact wire), bridge, tunnel and other, can bring new measurement mushing error again, system detected still be difficult to really satisfy actual needs.
The utility model content
The purpose of this utility model is to provide a kind of electrification railway contact net of new model inspection vehicle bar bit test device for addressing the above problem, it is tested on the basis that combines in existing electric pole test and range pulse, the bar bit test device of inspection vehicle can be tested and the comprehensive location of mutual verification realization from different perspectives by the different operating unit that can cooperatively interact, with the cumulative errors and the multiple mushing error of proofreading and correct and the elimination system locatees, and can also further realize discerning the effect of the station track that inspection vehicle passes through a station, inspection vehicle is had important and practical meanings.
The bar bit test device of the utility model electrification railway contact net inspection vehicle, be at present by on the data handling machine that stores route lever position information database and the basis that comprises the data processing system that electric pole detecting unit that is arranged on the inspection vehicle pantograph and the range pulse structure of being controlled by the speed sensor that cooperates with axletree connect respectively, in said this data processing system, also be provided with and the joining gps satellite positioning unit of data handling machine.
