The invention discloses a kind of railway track construction safety pre-warning system and method, by installing vehicle-mounted terminal equipment ON TRAINS, obtain train real time GPS coordinate, travel speed and travel direction and upload onto the server；The handheld terminal that site operation personnel wear is obtained in ten kilometers of circumference and towards the train information of workmen's direction running according to current GPS coordinate from server, Distance Judgment train according to the speed of train and between the two reaches the time of workmen position and voice reminder workmen, and the prompting workmen being interrupted as time goes by, reach and evade in advance.Relative to traditional alarm mode, it is no longer necessary to set protection personnel in station, reduce human cost, especially when construct interval it is longer in the case of, this advantage becomes apparent from.
Description
Technical field
The present invention relates to Along Railway construction safety early warning technology field, and in particular to one kind is using GPS location in train
Railroad track locomotive early warning system and method for the track along Workers are alerted during arrival in advance.
Background technology
Work business, electric business personnel need along the railway safeguard railway throughout the year, check, repairing, with china railway
Constantly speed-raising, train speed is constantly accelerated, and the work business workmen of train railway to along causes safely very big threat.Why
Sample processing train speed raising brings the threat to workmen's personal safety to need regular maintenance railway support train with work business personnel
Normal operation between contradiction be exactly the problem of solution required for us.
At present, the technological means that railway personnel are used is：When a teams and groups need upper track to construct, it is necessary in iron
Protection personnel in station is set in curb line station, while front and rear 800 meters of settings safety measure at the construction field (site).When train close to when, by
Protected personnel in station notifies live protected personnel with fixed station, then notifies road under workmen by live protected personnel.
Because partial section is longer and with the continuous lifting of train speed, this traditional alarm mode can not be complete
Entirely timely to site operation personnel's early warning, greatly threat is caused to personal safety.
The content of the invention
For problem of the prior art, the present invention proposes a kind of railway track construction safety pre-warning system and method, passed through
Vehicle-mounted terminal equipment with high accuracy positioning is installed ON TRAINS, train real time GPS coordinate, travel speed and traveling side is obtained
To and upload onto the server；The Mobile portable formula terminal that site operation personnel wear is obtained according to current GPS coordinate from server
In ten kilometers of circumference and towards the train information of workmen's direction running, distance according to the speed of train and between the two is sentenced
Disconnected train reaches time and the voice reminder workmen of workmen position, and the prompting construction being interrupted as time goes by
Personnel, reach and evade in advance.
The present invention is for the technical scheme that is used of solution above-mentioned technical problem：
On the one hand the present invention provides a kind of railway track construction safety pre-warning system, and it includes some car-mounted terminals, some

Operating personnel's positional information that the train status information and hand-held mobile terminal that the mounted terminal that returns the vehicle to the garage and knock off is sent are sent, and deposited in data
Classification storage is carried out in storage unit；The data that information process unit is currently received according to server judge near operating personnel whether
Whether there are train operation and train towards operating personnel's direction running, if existing near operating personnel towards operating personnel's direction running
Train, then current train information is sent to hand-held mobile terminal, and continue to receive subsequent time train status information and carry out
Judge and information sends operation, until train rolls operating personnel's safe range away from.
On the other hand the present invention provides a kind of railway track construction safe early warning method, comprises the following steps：
S1, car-mounted terminal starts, and train GPS coordinate, train instantaneous velocity and travel direction, car-mounted terminal are obtained in real time
Set up and be connected by wireless communication networks with remote server, upload train status information；
S2, hand-held mobile terminal starts, and is set up and is connected by wireless communication networks with remote server, uploads and obtains in real time
Gps coordinate；
S3, remote server inquires about train coordinate after receiving operating personnel's coordinate of hand-held mobile terminal upload, sentences
Travelled in disconnected operating personnel's safe range with the presence or absence of train towards operating personnel, if in the presence of remote server is moved to hand-held
Dynamic terminal sends the train status information and the coordinate of other operating personnels；
S4, hand-held mobile terminal calculates train and arrived according to train and the coordinate information of operating personnel, the gait of march of train
Up to the time required to current location, and early warning is carried out by voice broadcast, at the same hand-held mobile terminal according to operating personnel's coordinate and
Train coordinate, and centered on current work personnel's coordinate, early warning relative position figure is drawn, it is real by hand-held mobile terminal screen display
When show.
The beneficial effects of the invention are as follows：
1. relative to traditional alarm mode, it is no longer necessary to set protection personnel in station, reduce human cost, especially work as construction
In the case that interval is longer, this advantage becomes apparent from；
2. with the continuous lifting of train speed, it is shorter and shorter to leave the time that track construction personnel are evaded for, compares
The time of consumption is shorter required for traditional alarm mode, this invention pre-alert notification to track construction personnel, can more timely lead to
Know track construction personnel；
3. reducing complex operations, it need to only set up and be connected with server, remaining all operation is completed by computer.
