Embodiment
Fig. 1 is the structure diagram of the utility model, and Fig. 2 is the principle schematic of the utility model, as shown in the figure, this reality
Apply the traffic accident alignment system in example；Including optical cable, optical time domain reflection unit and control main frame；
Optical cable, fixes along road and is laid in guardrail, for detect due to it is unexpected cause guardrail deformation or/and the temperature to raise when
The position surprisingly occurred；Optical cable (i.e. fibre optical sensor) is arranged in road drive test or/and the corrugated beam barrier of median strip
Or on concrete guardrail, the fixed form of optical cable can be the interval fixed setting screw on corrugated beam barrier or concrete guardrail,
Optical cable is fastened in screw successively, easy for installation, and fixing-stable is of low cost, and optical cable may be disposed at corrugated beam barrier or
The back side on concrete guardrail, reduction are exposed to the sun, and error is caused beneficial to avoiding bend from installing, while ensure the service life length of optical cable；
Optical time domain reflection unit, is arranged at the end of optical cable, for sending detection light and gathering the Time Domain Reflectometry letter of return
Number, the output terminal connection of its output terminal and control main frame；Optical time domain reflection unit launches detection light to optical cable (fibre optical sensor)
Signal, backscattering principle caused by the Rayleigh scattering and Fresnel reflection when being transmitted in a fiber using optical signal, online
Monitoring optical cable (fibre optical sensor) in real time, causes to adhere to the optical cable (optical fiber being installed on guardrail when accident shock guardrail occurs for vehicle
Sensor) interrupt (or stress) or when when vehicle spontaneous combustion causes temperature action, optical time domain reflection unit is monitored, by when
Domain reflected signal is uploaded to control main frame and is handled, and the optical time domain reflection unit is the prior art, and details are not described herein；
Control main frame, for calculating the position surprisingly occurred according to the otdr signal of optical time domain reflection unit；When
So, it is provided with control main frame existing according to otdr signal calculating end of cable to optical cable with broken point or pressure spot or heating
The software of point distance, according to the distance and the electronic map for defaulting in control main frame, control main frame can quickly detect the accident
The position of generation.
In the present embodiment, alarm unit is further included, the output terminal of the control main frame and the input terminal of alarm unit are electrically connected
Connect；The alarm unit can be audible-visual annunciator, when control main frame detects that outer generation signal, control main frame are single to alarm intentionally
Member sends alarm signal and detects the position surprisingly occurred.
In the present embodiment, the optical time domain reflection unit is arranged at the both ends of unit cable；Certainly, the both ends difference of optical fiber
The optical time domain reflection unit of setting is equipped with control main frame, and beneficial to when accident occurs at the same time at two or at three, the system is equal
