Abstract
The invention discloses a road traffic early-warning system, which can be installed on a common road, realize full-automatic detection of road traffic obstacle conditions and automatic send alarm information to relevant people such as a driver and the like in the case of road pass obstacles so as to realize early warning of abnormal traffic conditions. The basic principle of the invention is: arranging a signal transmission source and a signal receiver at proper positions on the road, and detecting whether the signal receiver receives a normal transmission signal of the information transmission source at a certain time interval so as to judge whether the signal transmission is blocked by an obstacle. As the signals have properties similar to the properties in light transmission in the method, if the signal transmission is blocked, traffic blocking obstacles highly possibly appear in the road. The invention has the characteristics of saving manpower along with simple installation, low price and obvious warning effect.
Description
Technical field
The present invention relates to road traffic condition abnormity early warning technical field.
Technical background
Social now, traffic is flourishing day by day, the various vehicles are exercised on road, brought huge facility for people's productive life, simultaneously because the road traffic abnormal conditions, for example obstruction, accident and cause on road, have a barrier, thus the road traffic accident that causes also becomes a major issue that influences traffic safety.
On some important traffic routes, if exist barrier, informing of must shifting to an earlier date will be by the driver here.The driver drives a conveyance when closing on barrier else if, just finds the road barricade thing, will cause serious traffic hazard easily.
The inventive method, designed and a kind of emphasis highway section road traffic condition has been carried out the method for no worker monitor, can realize under the unmanned situation to whether occurring the real-time monitoring of barrier on the road, if find that the obstacle road appears in road, to automatically be reported to the police, be had using value very widely.
Summary of the invention
The invention provides a kind of road traffic condition abnormity early warning method, comprising: road S, signal emitting-source A, signal receiver B, display R, time interval T, signal-less time T as a result
0, reset button C.
Signal emitting-source A is a kind of instrument that can transmit automatically, and the signal of its emission can be laser but be not limited only to laser.The signal that signal emitting-source A is launched can only be that similar light a kind of can not penetrate barrier () signal for example: earth or rock.
Signal emitting-source A and signal receiver B are placed on the diverse location of road S respectively.The part that the signal of signal emitting-source A emission passes road S, arriving signal receiver B.If the barrier on the road has appearred in this part of the road S that passes at the signal of signal emitting-source A emission, barrier is the transmission of the signal of disabling signal emissive source A emission so, thereby causes signal receiver B can't receive signal.
Signal emitting-source A constantly is transmitted to signal signal receiver B in each time interval T.If The coast is clear does not have barrier, then signal receiver B can both receive the signal of signal emitting-source A emission at each time interval T.But when barrier occurring on the road, barrier is with the transmission of disabling signal, and signal receiver B just can not receive signal again.When time that signal receiver B does not receive signal during greater than signal-less time T0, just can assert has barrier on the road.
Described road S is the road that is used to be monitored, and the target of monitoring is whether barrier is arranged on the road;
Described signal emitting-source A is used for sending signal at each described time interval T to described signal receiver B, and this signal can be a laser, but is not limited only to laser, is that similar light a kind of can not penetrate barrier () signal for example: earth or rock.
Described time interval T is used to stipulate that described signal emitting-source A sends the time interval of signal to described signal receiver B;
Described signal receiver B is used to receive the signal that described signal emitting-source A sends, and when not receiving after signal emitting-source A sends to signal, can judge whether not receive signal time greater than described signal-less time T
0, when greater than described signal-less time T
0, when having barrier, promptly described road S can send signal to the described R of display as a result, and the mode that sends signal can be to use mobile communications network, but is not limited only to this kind mode;
Described signal-less time T
0, be used for described signal receiver B and judge whether described road S has the directrix of barrier;
The described R of display as a result is used to receive described signal receiver B and transmits, and display result.
Described reset button C is used to the total system that resets.

Fig. 1 is the system layout synoptic diagram.
Embodiment
1, signal emitting-source A is a kind of instrument that can transmit automatically, and the signal of its emission can be laser but be not limited only to laser.The signal that signal emitting-source A is launched can only be that similar light a kind of can not penetrate barrier () signal for example: earth or rock.
2, signal emitting-source A and signal receiver B are placed on the diverse location of road S respectively.The part that the signal of signal emitting-source A emission passes road S, arriving signal receiver B.If the barrier on the road has appearred in this part of the road S that passes at the signal of signal emitting-source A emission, barrier is the transmission of the signal of disabling signal emissive source A emission so, thereby causes signal receiver B can't receive signal.
3, signal emitting-source A constantly is transmitted to signal signal receiver B in each time interval T.If The coast is clear does not have barrier, then signal receiver B can both receive the signal of signal emitting-source A emission at each time interval T.But when barrier occurring on the road, barrier is with the transmission of disabling signal, and signal receiver B just can not receive signal again.When time that signal receiver B does not receive signal during greater than signal-less time T0, just can assert has barrier on the road.
4, object such as flying bird also can block the transmission of signal, but these objects but generally can not continue the transmission (because the signal blocking time of flying bird generally can be greater than T0) of block signal, so just can determine exactly whether road has barrier as long as determine a suitable signal-less time T0 (value of general T0 is the integral multiple of time interval T).
When 5, on determining road barrier being arranged, signal receiver B can be to signal of display R transmission as a result, and the send mode of this signal can be realized by the mode of SMS or network, but is not limited only to this dual mode.Display R receives signal receiver B when sending to signal as a result, just shows that an information is as " front link is obstructed, please detour " etc.Blocking the way road barrier can be by reset button C, recovery system after removing.
