Specific embodiment
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that
Specific embodiment described herein is merely to illustrate and explains the present invention, is not limited to this
It is bright.
As shown in figure 1, hanging contact line in contact net according to the simple catenary of one embodiment of the present invention
The monitoring device of tenesmus includes photoelectric encoder 101, processing module 102, communication module 103 and power supply
Module 104, wherein：When the carrier cable slip band movable pulley that the simple catenary is hung in contact net is rotated
When, the rotation of the pulley drives the photoelectric encoder 101 to rotate；The processing module 102 is received
The output signal of the photoelectric encoder 101, according to the output signal calculate the slip of the carrier cable away from
From, contact line tenesmus distance is calculated according to the sliding distance of the carrier cable, and by the contact line for being calculated
Tenesmus distance sends remote control center to by the communication module 103；And the power module
104 are used to be supplied to the photoelectric encoder 101, the processing module 102 and the communication module 103
Electricity.
Preferably, the rotary shaft of the photoelectric encoder 101 is coaxial with the rotating shaft of the pulley.So,
Turbine RPM will be caused consistent with the rotating speed of photoelectric encoder 101.Fig. 2 schematically shows photoelectricity
The mounting means of encoder 101, the i.e. rotary shaft of photoelectric encoder 101 and the pulley of carrier cable 201
Rotating shaft 202 is coaxial.Fig. 3 schematically shows the pulley position signal that simple catenary is hung in contact net
Figure, wherein, label 1 is insulator, and label 2 is bracing wire, and label 3 is pillar, and label 4 is load
Rope, label 5 is dropper, and label 6 is contact line, and label 7 is pulley.
Photoelectric encoder 101 can be incremental optical-electricity encoder, absolute optical encoder etc..For example,
To guarantee accuracy and taking into account economy, photoelectric encoder 101 can select the increment photoelectric of 360 lines
Encoder.
The power module 103 can be any one in solar cell, friction generator etc. or two
Person.Friction generator can be existing any one nano friction generator, and, when using friction
When generator is as power module 103, need applied energy management circuit to stablize its output.Energy pipe
Reason circuit can be existing any circuit for stablizing the output of friction generator, no longer go to live in the household of one's in-laws on getting married herein
State.By being used as power module 103 using solar cell, friction generator etc., can save energy
Continued power can be realized again, nor needs artificial climbing shaft tower to change battery, saved manpower thing
Power.
Processing module 102 can process the output of photoelectric encoder 101 using mirror to frequency division counter principle
Signal.Illustrate by taking incremental optical-electricity encoder as an example below.The counting mirror of incremental optical-electricity encoder
Have much to method, for example, can be realized by software mode, also can be realized by hardware circuit.Either
Software mode or hardware circuit mode, it reflects all basically identical to counting principle, that is, work as increment photoelectric
When encoder is rotated forward, A phases are ahead of 90 ° of B phases.When incremental optical-electricity encoder is inverted, B phases
It is ahead of 90 ° of A phases.Can be determined according to the condition conversion of incremental optical-electricity encoder output signal
The steering of incremental optical-electricity encoder.Counting has 3 kinds of frequency dividing modes：Not frequency multiplication (X1) mode, two times
Frequently (X2) mode, quadruple (X4) mode, each cycle count value adds (subtract) 1 in X1 modes,
Arbitrary next state switch count value of the X2 modes only in a certain phase adds (subtract) 1, X4 modes then in office
Arbitrary next state upset count value of one phase adds (subtract) l.
Processing module 102 can also be realized using inquiry mode the pulse of photoelectric encoder 101 reflect to
Count.In this case, the processing module 102 can include single-chip microcomputer 302 and decoder 301,
As shown in figure 4,301 pairs of photoelectric encoders 102 of the decoder output signal (i.e. A phases and
B phase signals) enter row decoding and decoding result is exported to the single-chip microcomputer 302, the single-chip microcomputer 302
The sliding distance of carrier cable is calculated according to the decoding result.Wherein, decoder can adopt 74LS139
Decoder, single-chip microcomputer 302 can adopt MSP430F149 single-chip microcomputers, and the single-chip microcomputer is low in energy consumption, speed
Hurry up, quality it is superior, fully meet control and the calculating demand of monitoring device of the invention.This is
A kind of example, the decoder and single-chip microcomputer of other models are also feasible.In order to ensure by regular time
It is spaced, preferentially completes inquiry, using an internal timing counter of single-chip microcomputer 302 as inquiry clock,
And this timer interruption priority level is set to into highest.So, A, B phase of photoelectric encoder 101
Output signal is imported in decoder 301 enters row decoding, and the signal after decoder 301 is decoded is transfused to
To in single-chip microcomputer 302 for travel direction differentiation, exemplary output waveforms such as Fig. 5 institutes of decoder 301
Show, state transition graph as shown in Figure 6 is obtained according to this output waveform.At aforesaid quadruple (X4)
Under mode, along any State Transferring of the "+" direction of arrow, counter adds 1；Along "-" arrow side
To any State Transferring, then counter subtracts 1；When other State Transferrings occur, counter keeps not
Become.Due to decoder 301 at any time only one be output as it is low, therefore with directly inquire about photoelectricity volume
A, B phase output signal of code device 101 is compared, and when State Transferring judges, byte is judged to be converted into
Position judges that condition adjudgement code is reduced to 1 by least 3, can greatly improve executing efficiency.
It should be pointed out that in Fig. 5, the time span of high and low level is only example, the guarantor of the present invention
Shield scope is not limited, namely the present invention is required the time span of low and high level without special.
In addition, when the pulse that photoelectric encoder 101 is realized using inquiry mode is reflected to counting, having
2 problems should be noted：
A. the setting at query time interval is not less than the maximum execution time of interrupt routine, wherein interrupting journey
Sequence refers to the processing routine of single-chip microcomputer 302, and maximum execution time includes single-chip microcomputer 302 according to pulsimeter
Calculate sliding distance and the time being transferred to needed for communication module 103.
If b. setting query time at intervals of t, the line number of photoelectric encoder 101 is R, then photoelectricity is compiled
The maximum speed n of code device 101 should meet t<(derivation of the formula is 1/4Rn：N is rotating speed, single
Position is revolution per second, and R is the umber of pulse of line number, i.e. every revolution, so the time of every revolution is
1/n, when a length of 1/Rn of each pulse, and it is quadruple that design here, so query time
t<1/4Rn), at least sampled 2 times with ensureing each state, it is ensured that counting is not lost.
In short, the sliding distance for assuming carrier cable is d, the output state of photoelectric encoder 101 changes
Number is m, then the sliding distance of carrier cableWherein R is photoelectric encoder 101
Line number, r is pulley radius.According to carrier cable sliding distance obtain contact line tenesmus distance be：
This be byWithIt is derived by.
