In the construction section of skylight phase；
When c, having train mistake into the construction section for being in the skylight phase, when the distance of train and job location is less than 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, step e is performed when workmen hears alarm and timely action, step is performed when workmen does not withdraw in time
Rapid f；
E, ground early-warning terminal, the first alarm module, the second alarm module and the 3rd are closed when all workmens withdraw
Alarm module is sounded all clear, and train passes through construction section with normally travel speed；
F, when train passes through the point type electromagnetic inductor set, vehicle-mounted electromagnetic inductor receives the point of ground setting
The signal that formula electromagnetic inductor is sent, train braking device start Braking mode Train Stopping；
G, workmen's construction finishes transmission when withdrawing job location and closes ground after withdrawing information to station monitor terminal
Construction section is added normally travel train path by Forewarning Terminal, station staff.
Operation principle of the present utility model is：
The fundamental difference of the utility model and traditional railway construction safety protection prior-warning device is, is not provided only with ground
Forewarning Terminal and vehicle-mounted Forewarning Terminal, are additionally provided with station monitor terminal.Wherein, ground early-warning device can integrate and be made as one
Individual less handheld terminal, is convenient for carrying.When ground early-warning device enables, ground early-warning terminal and station monitoring and early warning terminal
Communicated by the second wireless communication module, while the positional information that ground based terminal GPS module is measured is transferred to station prison
Control terminal, the real-time position information of ground based terminal is intuitively reflected with map view on the display screen of station monitor terminal
Come, while the 3rd alarm module sends alarm, reminds station staff's line construction situation, station staff adjusts train
Circuit avoids job location, in order to avoid staff forgets forward box hot work in progress, train is let pass by mistake and arrives front section, is caused
Accident.
In addition, vehicle-mounted Forewarning Terminal is communicated by the first wireless communication module with ground early-warning terminal, 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 send the default language such as " road work ahead, please braked immediately "
Sound, the second alarm module of ground early-warning terminal send 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, it 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 opening position 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, the stability and validity of system are more
It is good.In addition, the module that system uses is low-power consumption, the module of function admirable, therefore it is simple system, convenient, cost is cheap, can
Implementation is extremely strong.
One of ordinary skill in the art can these technical inspirations according to disclosed in the utility model make and various not taking off
From the other various specific deformations and combination of the utility model in essence, these deformations and combination are still in protection of the present utility model
In the range of.
