The function of sending.
Transmitter unit 70 can in a wired fashion or wireless mode is mutually communicated with multiple sensors 30, and to sensor
30, which send test, instructs and the space length data fed back received from sensor, and with it is anti-by the institute of sensor 30 under reset condition
The space length data of feedback are compared, and then calculate the deformation quantity of sensor 30 (such as in Fig. 1 and Fig. 2 by Heron's formula
Sensor 301 at institute M reaches the length in the path, i.e. straight line MM ' of the deformation of M ' places formation after differential settlement occurs
Degree).
In the present embodiment, the transmitter unit 70 be specially with data message receive with the sensor of sending function or
Laser generator.
It should be noted that in each embodiment of this specification, so-called " deformation quantity of sensor " refers specifically to generation biography
The space position parameter that the first time of sensor after mounting is demarcated is anti-to the institute of transmitter unit 70 with succeeding state lower sensor 30
Difference caused by the spatial position data of feedback.This deformation quantity can be the generation of vertical direction space displacement it is (i.e. heavy
Drop or arch upward) or the space displacement (i.e. lateral displacement) that occurs in the horizontal direction or on three dimensions
Any position offset.The deformation quantity of this sensor can be used to characterize displacement of the sleeper 90 on three dimensions.
In the present specification, by calculating the deformation quantity of sensor, sensing is fixed with one end end or both ends end
The track support means (such as sleeper 90) of device whether on three dimensions there occurs change in location to be characterized so as to track
The deformation such as the differential settlement that support device is occurred are monitored, show and alarm.
Join shown in Fig. 1 and Fig. 3, the present embodiment be specifically described when a sleeper 90 settles how detection sensor institute
The detailed process of the deformation quantity of generation.The sensor 301 in the left side of sleeper 90 is marked in original state (state when not deforming upon)
It is denoted as M, it is M ' that sensor 301, which produces the status indication after deformation quantity,.
In Fig. 1, sensor 301 is fixed on the both ends end of sleeper 90 with sensor 302, after sleeper 90 settles,
Sensor 301 ' and sensor 302 ' that the both ends of sleeper 90 ' end is fixedly installed simultaneously are controlled by collect and are disposed at reference point A
Transmitter unit 70 and collect the transmitter unit 70 disposed at reference point A, and can be to two 70 feedback airs of transmitter unit
Between range data.
Include specifically, whether above-mentioned Heron's formula calculating sensor deforms upon and (sedimentation occurs or arches upward) process
Following four sub-step：
Sub-step (1), structure original triangle ABM.
Sensor 301 at M is formed former to collecting reference point A and collecting reference point B reports and feedback space range data
Beginning triangle ABM.The distance of straight line AB can collect setting transmitter unit 70 at reference point A and collect setting at reference point B
Transmitter unit 70 is decided.Straight line MA and MB are can be carried out really from the space length data that two transmitter units 70 are fed back
It is fixed.Then, the area S of original triangle ABM is obtained according to Heron's formulaABM。
The area S of original triangle ABMABMCalculation formula it is as follows：
SABM=sqrt (p* (p-AB) * (p-AM) * (p-BM))；
Wherein, sqrt be rooting number mathematical operation symbol, p=(AB+BM+AM)/2.
Sub-step (2)：Build deformation rear triangle ABM '.
If the sensor 301 at M produces deformation and reaches M ' places.Sensor 301 ' is respectively to collecting at reference point A at this time
Transmitter unit 70 is set and sets transmitter unit 70 to report and update space length data reference point B at collecting, to be formed newly
Triangle ABM '.Then, the triangle area S after deformation is obtained according to Heron's formulaABM’。
Triangle area S after deformationABM’Calculation formula it is as follows：
SABM’=sqrt (p* (p-AB) * (p-AM ') * (p-BM '))；
Wherein, sqrt be rooting number mathematical operation symbol, p=(AB+BM '+AM ')/2.
Sub-step (3)：Assuming that deformation caused by sensor 301 is occurred along the vertical direction of track 40.Then may be used
The spatial position data structure straight line AH and straight line BG fed back in an initial condition according to reference point A and sensor 301 is collected.
On the direction deformed upon along the vertical direction of sensor 301, collect reference point A to collecting the sensors of reference point B extremely
The vertical range in the path (that is, straight line MM ') that 301 vertical direction is deformed upon can be also determined.
Point H is the intersection point for the reverse extending line for collecting reference point A and straight line MM ', and point G is to collect reference point B and straight line MM '
Reverse extending line intersection point.
Sub-step (4)：Deformation values MM ' is calculated, calculation formula is as follows：
MM '=(SABM-SABM’)*2/(AH+BG)。
Join shown in Fig. 5, there are multiple sleepers on website T to the double-rail track between website U, and in the both ends end of sleeper
Sensor 303a~sensor 303g, and sensor 313a~sensor 313g is fixedly installed.This specification is only to simplify
Represent, under actual conditions, the quantity of sensor installation is more than shown in Fig. 5.
When MM ' be on the occasion of when, real-time deformation quantity curve is higher than track datum line 100 (i.e. there occurs the phenomenon that arches upward at this time),
When MM ' is in negative value, real-time deformation quantity curve is less than track datum line 100 (i.e. there occurs sedimentation phenomenon at this time).When real-time shape
When variable curve is in the deformation threshold range delimited, system thinks the sedimentation of track or the degree that arches upward is still in reasonable model
In enclosing.Deformation threshold value can be delimited by dotted line 101 and dotted line 102 in the graph.Some sampled point of real-time deformation quantity curve
When 200 data are less than dotted line 102 or higher than dotted line 101, it can show that alarm carries by warning device 81 and/or display device 80
Show.
Join shown in Fig. 2 and Fig. 6, the principle as obtained MM ' deformation values in figure 1 above, can also variation, such as, only allow M
The sensor 301 at place only to collect reference point A or collect disposed at reference point B transmitter unit 70 feedback deform upon before
Space length data afterwards, and the deformation values MM ' of sensor 301 is calculated according to above-mentioned sub-step (1)~sub-step (4).
At this time, all reference points of collecting are planned in the side of track 40.
Finally, when the deformation quantity exceedes the deformation threshold value of setting, the changed sensor in locus is carried out
