Description
Technical field
The utility model belongs to security protection early warning technology field, more particularly to a kind of railroad train is close to prior-warning device.
Background technology
Safety is the guarantee of railway transportation, with the completion of railway the sixth time speed-raising and starting for EMUs, train fortune
Row F-Zero up to 300 kilometers/hour, be greatly improved people go out convenience while, to railroad maintenance workmen's
Safety also constitutes bigger threat, and this security protection just to workmen proposes higher requirement.
To reduce the loss of the country and people's property, the safety of people's life is ensured, both at home and abroad existing many units and section
Grind mechanism and carried out substantial amounts of research on this question, also have developed diversified train approach warning device.The method of use
Mainly there is the running signal for directly receiving train, or sense train signal with electromagnetic sensor in orbit, some is even
It could be alarmed after rolling.All there is such or such deficiency and defect for these methods.As above, down train is difficult to accurately
Differentiate, occur erroneous judgement in tunnel and even fail to judge, it is difficult to accomplish the train arrival that gives warning in advance, and give warning in advance and only gather train letter
Number, but directly train operation signal cost is larger is also not easily accomplished very much for collection.
And the special Important Sections such as bridge, tunnel, mine in railway are directed to, some secure early warning means are employed,
But cost is of a relatively high, it is difficult to is promoted the use of in the very long railway line in China, it is also difficult to adapts to China's long rail railway now
Requirement.
The content of the invention
In view of the above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of railroad train close in advance
Alarm device, realize the security protection of railway intersection vehicular traffic pedestrian and the person peace of railway maintenance construction of prevention work personnel
All risk insurance hinders.
In order to achieve the above object, the utility model adopts the following technical scheme that：
A kind of railroad train is close to prior-warning device, including adsorbs the rail when detecting train driving on the rail of early warning position
The vibrating sensor 1 of vibration signal, the data of the vibration signal of rail are adopted during the reception train driving being connected with vibrating sensor 1
Storage 2, what is be connected with data acquisition unit 2 is converted to rail vibration signal the D/A converter 3 of electric signal, with D/A converter 3
The voltage comparator 4 by the electric signal received compared with setting value of connection, be connected with voltage comparator 4 by rail vibration
The display 5 that the waveform and train approach warning information of electric signal are shown, in addition to sent with what voltage comparator 4 was connected
The acoustic-optic alarm 6 of sound and light alarm.
The advantages of the utility model and good effect are：
The utility model train approaching prewarning device is using the method for detection and analysis rail vibration information to Train Approaching
Early warning is carried out, according to wheel track excitation sound and solid acoustic propagation rule, proposes that one kind changes come pre- using solid sound in rail is measured
The method for reporting Train Approaching, this method is not limited by long and short rail can be widely popularized use in China railways system, carry significantly
The high safety guarantee of construction of railways personnel.
Relevant present Research is both at home and abroad understood, existing Train Approaching method for early warning has been analyzed, it is proposed that pass through
The solid sound propagated realizes Train Approaching early warning in detection and analysis rail.When row reach range sensor close to 1000 meters
During scope, prior-warning device sends acousto-optic early warning.
The train approaching prewarning device designs for the particular problem that the current railway system is faced safely, realizes iron
The security protection of road intersection vehicular traffic pedestrian and the personal safety guarantee of railway maintenance construction of prevention work personnel, the present apparatus pair
Long and short rail no requirement (NR), to running environment also without particular requirement, without intervening railway operation system acquisition information, independent operating, make
With facilitating operating cost low, it is easy to be widely applied.

Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows.
Structure of the present utility model is explained in detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of train approaching prewarning device of the utility model, including vibrating sensor 1, vibrating sensor 1
On rail, vibrating sensor 1 is connected with data acquisition unit 2 for absorption；Data acquisition unit 2 is connected with D/A converter 3, D/A conversions
Device is connected with voltage comparator 4；Voltage comparator 4 is connected with display 5, and the rear end of voltage comparator 4 connects acousto-optic report simultaneously
Alarm device 6.
Operation principle of the present utility model：Before railroad maintenance workmen constructs along the railway, at the construction field (site) outside
Vibrating sensor 1 is adsorbed on rail, when row reach range sensor close to 1000 meters of scopes, vibrating sensor 1 can
The rail vibration signal received is sent to by the vibration signal of rail during accurately detecting train driving, vibrating sensor 1
Data acquisition unit 2；The rail vibration signal received is transferred to D/A converter 3 by data acquisition unit 2, and D/A converter 3 is by steel
Rail vibration signal is converted to electric signal, is then transferred to voltage comparator 4, voltage comparator 4 is by the electric signal received with setting
Definite value (the voltage amplitude of rail vibration when train is previously provided with voltage comparator 4 apart from 1 different distance of vibrating sensor
Value, can set different alarm distances) relatively after, by the waveform of rail vibration electric signal and train approach warning information aobvious
Show and shown on device 5, while voltage comparator 4 triggers acoustic-optic alarm 6 and sends sound and light alarm, reminds pedestrian or safeguards and applies
Worker person pays attention to avoiding train.
