Compared to existing technologies, substantive difference is as follows for the present embodiment：

Current track structure monitoring device is all live measurement of near distance mostly, by sensor, trackside field monitoring extension set It is formed Deng part, is primarily directed to test in steering unit or the single area of railway frog part.Such measurement scheme, leads When a time train of cause passes through track switch, such as reverse cross is branched off, that is, is installed after first passing through steering unit by railway frog part, collecting device In steering unit（Railway frog part）, just can only obtain steering unit（Railway frog part）Data-signal, train can not be obtained and passed through When the complete signal period.

But train by when accurate positionin, timely early warning and maintenance decision of the complete signal period for trouble point Play the role of vital.For example, by taking foregoing reverse trouble excessively as an example, when a train is by changing points area, host computer mould Block virtual monitor program display data exception if measured at this time using single area, can not judge it is switch structure There are disease or train wheel existing defects, can only wait next train by when judge, signal still then track switch extremely There are disease, a signal then upper train wheel existing defects without exception in turn-out track area；If at this time using synchro measure side Case, then can from this coastiong by track switch railway frog area when, upper computer module virtual monitor program display data are judged, signal Still abnormal then train wheel existing defects, signal is without exception, and disease occurs in changing points area.

It can thus be seen that the synchro measure in changing points area and railway frog area, passes through track switch using a train Breakdown judge is carried out, the positioning result of high-precision and high stability can be obtained, improves track switch equipment protection, simplifies and accelerate rail The maintenance and repair of road structure, so as to improve the reliability of railway points system military service performance.The Switch monitor of the present embodiment is surveyed Amount method and system can reflect track switch total system dynamic duty status in real time, be carried to construct railway switch system safe operation Powerful guarantee is supplied.

For track switch, it is remote that the distance between turn-out track area and railway frog area are usually separated by tens of rice, in order to realize steering unit and The synchronous acquisition of railway frog part then needs the data cable being laid with connection span larger.In remote, long term monitoring requirement Under, cause the loss of signal from collection in worksite equipment to upper computer module very high, at present entire track switch service state measurement system System and data handling system are imperfect or accuracy is not high.For railway switch feature, switch monitor system be made it is more superior, More intelligent is current active demand.Around switch monitor system, switch monitor system is used zoning monitoring by the present embodiment, It is divided into 2 Liang Ge synchronism detections area of turn-out track area 1 and railway frog area, establishes turn-out track area RT.vi main programs and the main journeys of railway frog area RT.vi respectively Sequence by GPRS DTU modules, using GPRS mechanicss of communication, is completed real-time, interactive with the UI.vi main programs of host computer 13, is solved Cable arrangements are complicated, moisture-proof wetting resistance is poor, anti-electromagnetic interference capability is low, long-term in live large span multi-measuring point measurement monitoring Use easy the problems such as null offset occurs.

As shown in figure 3, after the monitoring system in application the present embodiment carries out 60 days, changing points area point rail position is surveyed The dynamic strain size of point, Fig. 3（a）For the measurement result of conventional monitoring methods, Fig. 3（b）For the survey of monitoring method in the present embodiment Measure result.

As can be seen from Figure 3：

First, for measurement accuracy requirement, particularly in the case of long term monitoring, conventional monitoring methods null offset shows It as serious, data section signal distortion, may have no idea to continue to measure, reason is the measurement monitoring of large span multi-measuring point Middle cable arrangements are complicated, anti-electromagnetic interference capability is low；But the monitoring method of the present embodiment can still work, using turn-out track area 1 and 2 subregion of railway frog area measurement mode, trans-regional cable distribution is not required, this loss for just efficiently solving data-signal is asked Topic and accuracy problem.

Second, for measuring stability requirement, conventional monitoring methods are the updates by collection in worksite equipment in itself, are improved The stability of acquisition terminal module, but this way is not only with high costs, on long terms, effect is not also notable；This reality It is relatively reliable to apply the monitoring method of example, communication module is increased from node from node and railway frog area 2 by turn-out track area 1, is reduced multiple For the adverse effect of monitoring system, signal data is relatively stable, makes long-term monitoring management towards promotion recognition accuracy in heterocycle border Aspect is further.

3rd, for service life requirement, switch monitor system cable run usually places an iron railway by track, in semi-nudity Dew or full exposed state, moisture-proof wetting resistance is poor, and anti-vibration, capability of resistance to radiation are low, it is contemplated that long term monitoring, later maintenance cost Higher, therefore, it is necessary to which the long term distance for reducing cable run uses, the present embodiment is substantially reduced using the method for zoning monitoring Circuit is worn, and O＆M cost reduces, and service life is more permanent.

In conclusion the present embodiment improve Switch monitor measurement accuracy, stability and life cycle etc. compared to There is obviously advantage for the prior art, the solution of track switch military service performance monitoring is not to depend only on high-precision Collecting device, the signal processing algorithm of low-power consumption, the entire common progress for monitoring each link on chain can just ensure The progress of Switch monitor technology.

Although above example referring to the drawings elaborates the design of the utility model aim and embodiment, But those skilled in the art will realize that in the case where limiting the precondition of scope without departing from claim, still may be used To make various modifications and variations to the utility model, therefore do not repeat one by one herein.
