Description of drawings
Accompanying drawing 1 is a structural representation block scheme of the present utility model.
Accompanying drawing 2 is the workflow block diagrams in the case.
Accompanying drawing the 3, the 4th, the scheme drawing of described orbital data in coordinate.
The specific embodiment
As shown in Figure 1, described orbital data gather in real time with processing equipment by orbital data before behind the collection head, orbital data collection head, train parameter and environmental detection unit, speed and metrics calculation unit, data in real time processing unit, result output unit constitute; Data acquisition head, train parameter and environmental detection unit, speed and metrics calculation unit before and after the data input pin of data in real time processing unit connects respectively, the data after the processing are transferred to train telltale, train automatic controlling system, train rail operation control center by output unit.
Present case is provided with train parameter and environmental detection unit, and when data were carried out real-time comparative analysis, as essential condition, particularly emphasis was considered the influence of temperature to the track geometry size with train parameter and environment factor.Described environment comprises various weather and other environment factors that influence data acquisition and train operation.Described train parameter include but not limited to train sole mass, carrying quality, speed, length, highly, the partial content or the full content of width, geometric configuration, wheel diameter.
This device is provided with speed and metrics calculation unit, by the spacing between the collection head of front and back and the speed of a motor vehicle are calculated, determines image data and track strict synchronism location, to protect the accuracy of correction data.
Accompanying drawing 2 is workflow diagrams of described device, in the present case, adopts micro-computer technology to design each circuit, designs its corresponding software by workflow diagram, makes microcomputer circuit carry out the corresponding work program, has corresponding real time data acquisition and processing capacity.
By the foundation and the operation of this device, the track before can overcoming detects some limitation that behavior is checked for track condition.
For example, in the gauge test item therein, slighter gauge error signal is not easy to be detected by the gauge detection head of train front portion, also think to be lower than the failure warning value even perhaps detect, but, through after the rolling of whole train, this error may expand to much larger than the failure warning value, and, interval after train driving is in the short period, this gauge error may return to the state that is lower than the failure warning value again, so the gauge test item in the common rail inspection vehicle is not easy this fault detection is arrived, and this potential failure condition is easy to be detected by this device and report is come out.
Again for example, when running at high speed, train upwards flies up easily at some handstones on the track bed, parts to the train bottom constitute a threat to, because physics factor, these handstones generally fly up at the train rear portion, at this moment in the Acoustic detection project of this device, the signal that is positioned at the detected handstone collision of the acoustic sensor train base plate of train front portion is far smaller than the detected signal in train rear portion, the data of obtaining by the acoustic sensor that will be positioned at train front portion and rear portion compare analysis, whether have handstone fly up quality and the quantity of collision train and these handstones, for decision-making treatment provides foundation if just can tell easily.
In a reference case, the earthquake wave sensor that is positioned at the earthquake wave sensor of high speed train front portion and train rear portion detects track simultaneously and transmits stronger earthquake wave, promptly judge the possibility that has earthquake to take place, device sends caution, the while automatic train deceleration, continue and upgrading as seismic data, train promptly is decelerated to fully and stops, the danger of train overturning when avoiding earthquake.
Comparative analysis when " comparative analysis " as herein described comprises the comparative analysis of data synchronization comparative analysis, dynamic or static comparative analysis, real time data and historical data, comparative analysis, friction speed between the different vehicle etc.Comparative analysis can be finished by automatic comparative analysis of micro computer or artificial comparative analysis.
Shown in accompanying drawing 3,4, be described orbital data a1 and the a2 waveform scheme drawing in coordinate, abscissa is time t, ordinate is amplitude v.Orbital data a1 is produced by preceding data acquisition head, has wherein comprised track signal q1; Orbital data a2 is produced by back data acquisition head, has wherein comprised track signal q2.
In the data in real time processing unit, when orbital data a1 and data a2 were carried out real-time comparative analysis, key was will calculate with determining track signal q1 that same track point produces and signal q2 to lay respectively at the accurate position among orbital data a1 and the data a2.When train operation, above-mentioned track signal is constantly to produce, described track signal only be in the orbital data wherein certain is a bit.

Above-mentioned ' t2-t1 ' time is to determine by the spacing between the data acquisition head before and after train speed and the train, can use formula t=s/v (at the uniform velocity).When train speed changes, calculate this delay time and also will consider acceleration/accel.
Track signal can calculate and discern according to the distance between the collection head of front and back and the speed of a motor vehicle, or calculates and discern track signal q1 and the signal q2 that same track point produces in the orbital data according to the tracks positioned mark and the speed of a motor vehicle;
The data that orbital data a1 and data a2 obtain when vehicle parameter is identical before train normally moves can be carried out in real time comparison and analysis synchronously, for decision-making treatment provides foundation;
Adopt above-mentioned case study on implementation and method thereof, by all types of data that all types of collection heads obtain track are set, can analyze real-time dynamicly and handle the respective track test item, the data acquisition head that these track test items use comprises the high-speed camera head, laser scanning head, the degree of balance detection head, the gauge detection head, the flaw detection head, smooth-going degree detection head, pressure sensor, acoustic sensor, vibrations and earthquake wave sensor, speed sensor, acceleration pick-up, detection means and check implements such as electromagnetic sensor comprise the detecting instrument of certain individual event or multinomial detection.
Being appreciated that in actual applications also can increase new composition, to obtain more function or more performance.
For example, described identical data acquisition head is not limited to and is installed in anterior and two places, rear portion of train, in order to reflect the real-time status of track more accurately, can the data acquisition head identical with the collection head at train front portion or rear portion be installed at train one place, middle part or many places, to obtain more data.The various calculating of orbital data, comparison and analysis process also can be finished in the data in real time processing unit.
In a case, telltale mark has been installed in orbit equably, by the data acquisition head on train scanning and gather signal on the described telltale mark, in various calculating and comparison procedure to orbital data, orbital data a1 and orbital data a2 are proofreaded synchronously as synchronized positioning point by the signal that the tracks positioned mark is produced, the track signal q1 of same track point is overlapped on waveform with signal q2, make result accurate.
