Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely illustrated, it is clear that described embodiment is
Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
All other embodiments obtained without making creative work shall fall within the protection scope of the present invention.
Section configuration information memory is stored in by controlling to connect relay and pulse signal generation device and read
In section information, and according to section configuration information generate pulse signal；Wherein, it is stored in section configuration information memory
Section configuration information includes yard number, local area segment number, this section pulse transmission voltage, this section pulse transmission frequency, sheet
The information such as sector pulse peak head tail of the peak ratio (comparing end to end).
Pulse signal generator becomes the above-mentioned pulse of generation through sending end cable emulation network, sending end barrier box and sending end
Depressor etc. is transmitted to the sending end of rail.
Above-mentioned pulse signal is using rail as the receiving end of conductor propagation to rail, through the receiving end transformer and receiving end electricity
Signal enters the attenuation adjustment circuit after the transmission of cable analog network, and the signal transmission after attenuation adjustment circuit adjustment is extremely
Pulsed signal device.
Under normal circumstances, pulsed signal device receives normal pulse signal, as shown in Figure 2 normal letter
Number.There are two features for tool simultaneously for the pulse signal：(1) positive-negative polarity；(2) frequency characteristic.
From figure 2 it can be seen that normal signal has peak head UPeak headWith tail of the peak UTail of the peak.The pulsed signal device docking
The above-mentioned pulse signal received is detected, and determines the voltage value of peak head and the voltage value of tail of the peak, and then by corresponding device,
Such as acquisition module of detection device etc., it is calculated by the way of such as division operation and compared end to end：UPeak head/UTail of the peak。
In detection device corresponding memory module be previously provided with track section under normal circumstances compare range end to end.This is end to end
Manually setting or automatic setting can be carried out according to track section situation than range.It is preset end to end than preferred scope be 3:
1-8:Between 1, but the invention is not limited in this ranges, can suitably be adjusted, such as 4 according to actual conditions:1-8:
1 or 2:1-7:1 or 2:1-9:1 etc..
Obtained by acquisition module end to end than rear, corresponding module, for example, judgment module by this end to end than with it is above-mentioned default
Compared end to end than range, judge detection obtain end to end than whether dropping into above-mentioned preset range.
After damage in insulation occurs in track section, the pulse signal for having contiguous segment invades section.The present invention is implemented
The signal of intrusion is known as intrusion signal, intrusion signal as shown in Figure 2 in example.After intrusion signal invades track section,
The tail of the peak U of intrusion signalIntrusionIt can be added in normal signal, interference is also just produced to normal signal.At this point, pulse signal connects
Receiving apparatus receive pulse end to end than U can be becomePeak head/UIntrusion.Due to the intrusion of intrusion signal so that end to end than changing,
Range will be compared end to end beyond preset.
The acquisition module of detection device obtains peak head voltage value, the tail of the peak voltage value of pulse signal, and then passes through above-mentioned fortune
Calculation mode is compared end to end, at this time due to the intrusion of intrusion signal, end to end than becoming UPeak head/UIntrusion.Corresponding judgment module should
End to end than with it is above-mentioned it is preset compared end to end than range, determine that detection obtains end to end than whether this preset compares model end to end
In enclosing.If it does not fall under in the range of this, such as beyond preset end to end than range or less than end to end than preset range, then phase
Track section is determined as damage in insulation by the module answered, such as determination module.
After damage in insulation is determined as, relay can be disconnected, completes damaged check at this time.
Further, the embodiment of the present invention can also utilize the situation of change of this section pulse signal frequency can at the same time
Further strengthen the function of its damage in insulation inspection.
(1) after damage in insulation, adjacent sections signal can invade this section, and such intrusion signal is superimposed local area segment signal,
Can not only influence signal end to end than size, can also change the frequency of signal, such as shown in figure 3, this section signal frequency is
f1=3Hz, adjacent sections signal frequency are f1=4Hz, works as f2And f1After Signal averaging, frequecy characteristic will change；
(2) when detecting that signal frequency is not inconsistent with this section default frequency, also it is determined as damage in insulation；
(3) therefore using end to end than judging damage in insulation with two features of frequency, wherein when being unsatisfactory for there are one condition
Judge damage in insulation, so strengthen damage in insulation audit function.
Method and step in embodiments of the present invention can be performed in corresponding module, these modules are not limited to hardware
Unit, the applicable present invention of software, firmware.Therefore, method and step of the invention can be by what computer program controlled
It unites to realize.Therefore, ground is corresponded, also a kind of damage in insulation detecting system is provided simultaneously in the embodiment of the present invention,
It includes：Memory；And one or more processors；
Wherein, the memory is connect with one or more of processor communications, and being stored in the memory can quilt
The instruction that one or more of processors perform, described instruction is performed by one or more of processors, so that described one
A or multiple processors can realize the method for the present invention.
Meanwhile the present invention also provides a kind of computer program products, the computer product, which includes computer, to be held
Row instruction, the computer executable instructions can perform the method described in above-described embodiment.
Through the above description of the embodiments, those skilled in the art can be understood that each implementation step
The mode of required general hardware platform can be added to realize by software, naturally it is also possible to be realized by hardware suddenly.Based on this
The understanding of sample, the part that above-mentioned technical proposal substantially in other words contributes to the prior art can be with hardware product, software
The form of product embodies, the computer software product can store in a computer-readable storage medium, as ROM/RAM,
Magnetic disc, CD etc. are used including some instructions so that a computer equipment (can be personal computer, server or net
