Description
Technical field
The utility model belongs to technical field of rail traffic, especially relates to a kind of anti-collision early warning system of track train
System.
Background technology
As economic is flourished, into 21st century after the modernization of China constantly accelerate, urbanization is entered
Journey is maked rapid progress.And deepening continuously with urbanization process, the increasingly increase of China's urban population, to urban public transport
Demand also increasingly increases.Although urban rail transit in China career development is rapid, the anti-collision early warning system of city railway train
System is but in the state for relatively lagging behind.In recent years, just there are a lot of train operation accidents, city rail row in China city rail train
The passenger traffic volume of car system is very high, and the seriousness of accident can not be ignored.Because train is during actually operation, may require that sometimes and cut
Except ATP automatic protective systems, now the safety in operation of train is greatly lowered, and only relies on the modes such as traditional telephone block system and is difficult
The operation safety of train is ensured completely.Therefore need badly in the middle of prior art and want a kind of new technical scheme and ask solving this
Topic.
Utility model content
Technical problem to be solved in the utility model is：A kind of anticollision auxiliary early warning dress of city railway train is provided
Put, based on linear frequency modulation spread spectrum signalling technique and symmetrical bilateral round trip distance-finding method, can in real time measure this car with equidirectional operation
Front truck distance, be embodied as driver provide safe distance acousto-optic warning, remind driver take the related measures such as reduction of speed or braking,
Prevent train from overtaking collision.
A kind of anticollision auxiliary prior-warning device of city railway train, it is characterized in that：Including system host, rangefinder, alarm
Device, RFID input module, the system host, rangefinder and warning device are two, and are respectively provided with
In the drivers' cab of the rear and front end of track train；The two systems main frame mutually company of communicating at the same track train two ends
Connect；The RFID input module is two, is separately positioned on the bottom at track train two ends；
Signal output part, the survey respectively with RFID input module of the signal input part of each system host
The system host signal output part connection of the signal output part of distance meter and opposing train to be measured or same direction train；It is described each
The signal output part of system host is connected with the signal input part of warning device.
The warning device includes police instruction flash lamp and police instruction jingle bell.
By above-mentioned design, the utility model can bring following beneficial effect：A kind of city railway train it is anti-
Auxiliary prior-warning device is hit, monitoring train can be in real time measured and with vehicle distances between track front truck, and distance reaches between two cars
Sound and light alarm is sent during to alert threshold, reminds driver to take the related measures such as reduction of speed or braking, multistage is capable of achieving according to setting
Early warning.Rangefinder above train operator room, can communicate, by Chrip with the rangefinder on other trains
Signal fast and accurately obtains two car relative distances using the distance measuring method of bilateral round trip, contrasts traditional wireless location technology big
The big anti-interference and certainty of measurement that improve range finding.Warning device is installed on train operator's platform, while providing acousto-optic two kinds of reports
Police's formula, facilitates and fast and effectively obtain warning message in driver driving.RFID input module is arranged on train bottom
The relevant informations such as portion, up-downgoing during reading train operation, for distinguishing whether train runs in same track.System host collects
Rangefinder, RFID input module, input train there is OFF signal to judge, Ruo Benche with co-orbital front truck
Between hypotelorism, system host sends alarm signal and sends alarm to driver by alarm module.
Brief description of the drawings
The utility model is further described below in conjunction with the drawings and specific embodiments：
Fig. 1 aids in the structural schematic block diagram of prior-warning device for a kind of anticollision of city railway train of the utility model.
1- system hosts in figure, 2- rangefinders, 3- warning devices, 4-RFID electronic tags input module, 5- other trains
Input information.
Specific embodiment
The anticollision auxiliary prior-warning device of a kind of city railway train, as shown in figure 1, including system host 1, rangefinder 2, report
Alarm device 3, RFID input module 4, the system host 1, rangefinder 2 and warning device 3 are two, and divide
It is not arranged in the drivers' cab of the rear and front end of track train；The two systems main frame 1 at the same track train two ends is mutual
Communication connection；The RFID input module 4 is two, is separately positioned on the bottom at track train two ends；
The signal input part of each system host 1 signal output part respectively with RFID input module 4,
The system host signal output part connection of the signal output part of rangefinder 2 and opposing train to be measured or same direction train；It is described
The signal output part of each system host 1 is connected with the signal input part of warning device 3.
The warning device 3 includes police instruction flash lamp and police instruction jingle bell.
The system host 1 is input into information 5 and sentences according to rangefinder 2, RFID input module 4 and other trains
Disconnected train whether there is the danger for colliding, and remind driver to take by the multistage sound and light alarm of warning device 3 if having
Corresponding measure avoids colliding.
It is relative that the rangefinder 2 fast and accurately obtains two cars by Chrip signals using the distance measuring method of bilateral round trip
Distance.
The multistage sound and light alarm of the warning device 3 is classified according to the given threshold of safe distance.
The relevant informations such as the up-downgoing during reading of RFID input module 4 train operation, arrange for distinguishing
Whether car runs in same track.
The utility model can in real time measure monitoring train and with vehicle distances between track front truck, and the distance between two cars
Sound and light alarm is sent when reaching alert threshold, reminds driver to take the related measures such as reduction of speed or braking, be capable of achieving according to setting many
Level early warning.
A kind of city railway train anticollision auxiliary prior-warning device of the utility model uses the positioning distance measuring scheme of 2.4G, bottom
Modulation technique increases measurement range using CSS core technologies on piece using Chip signal characteristics, makes the detecting distance model of rangefinder 2
Enclose up to 800 meters~2000 meters；Device uses advanced TDOA technologies simultaneously, counteract in ranging process because the time is asynchronous
The shake for bringing, the range accuracy for greatly improving, the present apparatus is directed to the non-ideal environmental factor in tunnel, signal attenuation, train line
The influence of layering and track nearby with frequency band signals to system is analyzed, and is totally independent of signal system and radio communication system
System.Completely range finding distance is not less than 400m, can adapt to maximum speed 120km/h and following train.According to safe distance, to
Driver provides risk distance early warning and brake hard early warning, equipment working state show and fault message shows, is cut in ATP
In the case of removing, realization measures this car and the distance of the front truck of equidirectional operation in real time, for driver provides the police of safe distance acousto-optic
Show, prevent train from overtaking collision.
