Description
Technical field
The present invention relates to a kind of early warning system for construction of railways security protection.
Background technology
Railway due to the features such as its is cheap, security is good, be Chinese national economy development basis.In recent years, railway
Mileage constantly expands, and rail track is conveyed to be needed to carry out it work such as substantial amounts of maintenance, maintenance after a large amount of trains, and linemen's
When people carries out line construction, existing safety protection equipment is typically that the construction period of the circuit is set to by station staff
" skylight " phase, train of not letting pass enters the construction area, while site operation workman on ground by setting safeguard, when having
When train is by the safeguard, alarm is sent to line construction workman.These safety prevention measures are all not comprehensive enough, easily lead
Cause train to swarm into construction area and occur train pedestrian accident.
Pass through the combing to existing construction of railways safety protection facility, it is found that existing protective equipment is only from one
Or two aspects are protected, do not monitored from station staff, engine driver and construction worker three aspects are entered
The comprehensive protection of row, and automaticity is not strong.Meanwhile, existing system is opened based on the conventional one-piece machine mostly
Hair, systematic function is poor, particularly in practical application.
The content of the invention
The purpose of the present invention, aiming above mentioned problem, proposes a kind of automatic early-warning for construction of railways security protection

The present invention implementation be：
The positional information that a, the workmen of job location gather d GPS locating module is sent to by ground early-warning terminal
Station monitor terminal, the image procossing display module of station monitor terminal shows the positional information and the 3rd alarm mould of job location
Block sends alarm；
B, station staff hear that alarm confirms job location, and adjustment train driving route does not let pass train at front
In the construction section of skylight phase；
C, have train mistake enter in the skylight phase construction section when, when train and job location distance be less than it is vehicle-mounted
During the transmission range of Forewarning Terminal and the first wireless communication module of ground early-warning terminal, the first alarm module, the second alarm mould
Block and the 3rd alarm module send alarm, and workmen withdraws job location；
D, workmen perform step e when hearing alarm and timely action, and step is performed when workmen does not withdraw in time
Rapid f；
Ground early-warning terminal, the first alarm module, the second alarm module and the 3rd are closed when e, all workmens withdraw
Alarm module is sounded all clear, and train passes through construction section with normally travel speed；
F, when train through setting point type electromagnetic inductor when, vehicle-mounted electromagnetic inductor receive ground setting point
The signal that formula electromagnetic inductor is sent, train braking device starts Braking mode Train Stopping；
G, workmen's construction finish transmission when withdrawing job location and close ground after withdrawing information to station monitor terminal
Construction section is added normally travel train path by Forewarning Terminal, station staff.
The present invention operation principle be：
The present invention and the fundamental difference of traditional railway construction safety protection prior-warning device are, are not provided only with ground early-warning
Terminal and vehicle-mounted Forewarning Terminal, are additionally provided with station monitor terminal.Wherein, ground early-warning device can with it is integrated be made as one compared with
Small handheld terminal, is convenient for carrying.When ground early-warning device is enabled, ground early-warning terminal passes through with station monitoring and early warning terminal
Second wireless communication module is communicated, while the positional information that ground based terminal GPS module is measured is transferred to station monitoring eventually
The real-time position information of ground based terminal is intuitively reflected with map view on end, the display screen of station monitor terminal, together
When the 3rd alarm module send alarm, remind station staff's line construction situation, station staff adjustment train line
Job location is avoided, in order to avoid staff forgets forward box hot work in progress, train is let pass by mistake and arrives front section, thing is caused
Therefore.
In addition, vehicle-mounted Forewarning Terminal is by the first wireless communication module and ground early-warning terminal communication, when train and construction
It is vehicle-mounted pre- when the distance in place is less than the transmission range of the first wireless communication module of ground early-warning terminal and vehicle-mounted Forewarning Terminal
Alert terminal is realized with ground early-warning terminal to communicate, while the alarm module of ground Forewarning Terminal and vehicle-mounted Forewarning Terminal all sends language
Tone alerts, the first alarm module of vehicle-mounted Forewarning Terminal sends the language of default such as " road work ahead is please braked immediately "
Sound, the second alarm module of ground early-warning terminal sends default such as " train arrival, the voice please walked quickly and kept away immediately.
So railway line construction personnel are pacified in terms of engine driver, workmen and station staff three
Full protection, can greatly improve the security of railway line construction personnel.
And when workmen can not withdraw in time and train operator is not stopped in time, train is by being arranged on railway
Point type electromagnetic inductor position at when, train braking device can enhance construction of railways with Braking mode Train Stopping
Security.
Meanwhile, system is developed using the more preferable embedded-type ARM module of performance, and the stability and validity of system are more
It is good.In addition, the module that system is used is low-power consumption, the module of function admirable, therefore it is simple system, convenient, it is with low cost, can
Implementation is extremely strong.
One of ordinary skill in the art can make various do not depart from originally according to these technical inspirations disclosed by the invention
The other various specific deformations and combination of essence are invented, these deformations and combination are still within the scope of the present invention.
