Abstract
The invention discloses a high-speed railway vehicle tailgating-prevention alarming method and device. A signal transmitter on a vehicle transmits signals of different frequencies around in real time, other vehicles receive the signals, and whether the possibility of tailgating of the two vehicles exists or not is judged according to different coverage ranges corresponding to the different frequencies and vehicle operation information data included in the signals, and alarming information is sent. According to the high-speed railway vehicle tailgating-prevention alarming method and device, installation is easy, functions are practical, and due to the fact that the signal coverage ranges of the signals of different frequencies are different, the driving directions of the vehicles are distinguished, the distance between the two vehicles is calculated and whether the tailgating risks exist or not is judged. Drivers of the front vehicle and the followed vehicle are informed of the information and reminded through a display device, meanwhile, optimal safe driving proposed schemes are given to the drivers to choose, and an early warning signal is sent to a dispatching center. The high-speed railway vehicle tailgating-prevention alarming device can effectively improve the reliability of a subway control system, prevent the tailgating accidents and ensure the traffic safety. In addition, timely, accurate and reasonable driving suggestions are provided for the drivers of cabs, and therefore the tailgating collision circumstances are avoided.

As shown in Figure 1, signal projector 1, signal receiver 2, data-analyzing machine 3, input display equipment 4, alarm device 5.
Specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail:
As shown in Figure 1, of the present invention is the anti-alarm device that knocks into the back of a kind of high speed railway car, is specially adapted to subway etc. and can not receives the guideway vehicle control system of GPS locating data.
This device is made up of signal projector 1, signal receiver 2, data-analyzing machine 3, input display equipment 4 and alarm device 5.Signal projector 1, signal receiver 2, data-analyzing machine 3, input display equipment 4 are all installed on a car of every row subway and trailer, and alarm device 5 is arranged on the control center at station.
The signal projector 1 of this car, signal receiver 2, input display equipment 4 are electrically connected with the data-analyzing machine 3 of this car respectively, signal projector 1, signal receiver 2 wireless connections of signal projector 1, signal receiver 2 and other vehicle of this car, alarm device 5 wireless connections of data-analyzing machine 3 and control center.
Wherein, the effect of signal projector 1 is the signal of launching towards periphery in real time different frequency by different emissive powers, the coverage of each frequency is all different, the corresponding coverage of each frequency numerical value, the vehicle that receives signal can judge the distance between vehicle and this car transmitting is how many according to the s-f receiving.In the signal that signal projector 1 is launched, all include the vehicle operation data such as travel way, departure time-table of this car, the vehicle that receives signal can judge that vehicle and this car of transmitting are to travel in the same way or backward going according to this, and is front or rear at this car.
The effect of signal receiver 2 is signals that include vehicle operation data of accepting in real time the different frequency of other vehicle transmission, and the signal of reception is transferred to data-analyzing machine 3.
The effect of data-analyzing machine 3 is the data that receive transmission from signal receiver 2, by the frequency data that receive distinguish the vehicle that transmits and this car be travel in the same way or backward going, be the front of this car or rear and and this car between distance etc., analysis has or not rear end collision, and obtaining corresponding safe driving scheme, it is the nucleus equipment of whole device.Data-analyzing machine 3 should have arithmetic capability at a high speed, can provide in time the driving proposed projects rationalizing most.
Data-analyzing machine 3 comprises data capture unit, calculating unit, judging unit and memory cell.Wherein, data capture unit obtains the frequency data of other vehicle transmitting from signal receiver 2; Calculating unit is used for according to the frequency data that receive, distance between the vehicle that calculates this car and transmit, this car and the vehicle transmitting are to travel in the same way or backward going and be front or the rear at this car, draw the result of calculation that whether has rear end collision; Judging unit, for having judged whether according to result of calculation the possibility that knocks into the back, if any the possibility that knocks into the back, sends alarm message by the mode of note to the alarm device 5 of control center, and judging unit is also for providing best driving scheme; Memory cell is for storing the data such as running velocity, travel way, frequency of frequency data, vehicle of real-time reception.
The effect of alarm device 5 is to receive with wireless modes such as notes the alarm message being sent by data-analyzing machine 3, and alarm message is finally presented on the control panel of control center.
Describe the anti-alarm method that knocks into the back below in detail:
Chaufeur, before subway starts, starts this device, and inputs the vehicle such as travel way, departure time-table operation information data by input display equipment 4.This device, in subway driving process, utilizes different emissive powers to launch towards periphery in real time the signal of different frequency by signal projector 1.In the frequency signal of transmitting, include the vehicle such as travel way, the departure time-table operation information data of this car.
The signal receiver 2 of another car is received after this signal, then the signal of receiving is transferred to the data-analyzing machine 3 of this car.The corresponding coverage of each frequency numerical value, the distance that the data-analyzing machine 3 of this car can calculate between vehicle and this car transmitting according to the coverage of the frequency numerical value receiving is how many, and this result of calculation is shown in real time on input display equipment 4, to remind chaufeur.Simultaneously, in the frequency signal of transmitting, include the vehicle such as travel way, the departure time-table operation information data of vehicle, the vehicle that receives signal can judge that according to these information this car and the vehicle transmitting are to travel in the same way or backward going and be front or the rear at this car, and then judges the two cars possibility that whether knocks into the back.
If data-analyzing machine 3 judges that vehicle and this car of transmitting travel in the same way, and the frequency coverage of launching is within the scope of the danger range that may cause rear-end collision time, two spacings are crossed while closely likely causing rear-end collision, mode by note is sent alarm to control center, simultaneously, data-analyzing machine 3 can also calculate best safe driving proposed projects, comprise and need to accelerate, or slow down, or " face and stop " etc. beyond the safety distance of front truck, result of calculation and suggestion are all presented on input and display device 4, chaufeur is driven according to suggestion.
As mentioned above, given scheme content, can derive similar technical scheme in conjunction with the accompanying drawings and embodiments.In every case be the content that does not depart from technical solution of the present invention, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present invention, all still belong in the scope of technical solution of the present invention.
