Fig. 1 is the fundamental diagram of the present invention.
As it is shown in figure 1, signal projector 1, signal receiver 2, data-analyzing machine 3, input display device 4, warner 5.
Specific embodiment
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
It is the anti-alarm device that knocks into the back of a kind of high speed railway car as it is shown in figure 1, of the present invention, is particularly well-suited to subway etc. and can not receive the rail vehicle control system of GPS location data.
This device is made up of signal projector 1, signal receiver 2, data-analyzing machine 3, input display device 4 and warner 5. Being fitted with signal projector 1, signal receiver 2, data-analyzing machine 3, input display device 4 on the head car and trailer of each column subway, warner 5 is arranged on the control centre at station.
The signal projector 1 of this car, signal receiver 2, input display device 4 electrically connect with the data-analyzing machine 3 of this car respectively, the signal projector 1 of this car, signal receiver 2 and the signal projector 1 of other vehicle, signal receiver 2 wireless connections, warner 5 wireless connections of data-analyzing machine 3 and control centre.
Wherein, the effect of signal projector 1 is the signal launching different frequency in real time towards periphery by different transmitting powers, the coverage of each frequency is all different, the corresponding coverage of each frequency values, according to the signal frequency received, the vehicle receiving signal can judge that the distance launching between vehicle and this car of signal is how many. The signal that signal projector 1 is launched all includes the vehicle operation data such as the traffic route of this car, departure time-table, the vehicle receiving signal can judge that the vehicle launching signal and this car are to travel in the same direction or backward going according to this, and is at the front of this car or rear.
The effect of signal receiver 2 is the signal including vehicle operation data accepting the different frequency that other vehicle sends in real time, and transmits the signal received to data-analyzing machine 3.
The effect of data-analyzing machine 3 is the data receiving transmission from signal receiver 2, distinguished by the frequency data received launch the vehicle of signal and this car be travel in the same direction or backward going, be the front of this car or rear and and this car between distance etc., analyze with or without rear end collision, and obtaining corresponding safe driving scheme, it is the nucleus equipment of whole device. Data-analyzing machine 3 should have operational capability at a high speed, can provide the driving proposed projects rationalized most in time.
Data-analyzing machine 3 includes data capture unit, computing unit, judging unit and memory element. Wherein, data capture unit obtains the frequency data of other vehicle emissions from signal receiver 2; Computing unit is for according to the frequency data received, calculate the distance between this car and the vehicle launching signal, this car and the vehicle launching signal are to travel in the same direction or backward going and be at the front of this car or rear, draw the result of calculation that whether there is rear end collision; Judging unit, for determining whether, according to result of calculation, the possibility that knocks into the back, if any the possibility that knocks into the back, then sends warning message by the mode of note to the warner 5 of control centre, it is judged that unit also provides for best driving scheme; Memory element is for storing the data such as the frequency data of real-time reception, the speed of service of vehicle, traffic route, frequency.
Input display device 4 is used for inputting the information such as traffic route, departure time-table, and the safe driving scheme of the result of displaying data in real-time analyzer 3 gained and suggestion, input display device 4 should be able to allow driver obtain data and the data needed at the very first time, destination locations of waking up.
The effect of warner 5 is to receive, with wireless modes such as notes, the warning message sent by data-analyzing machine 3, and warning message is eventually displayed on the control panel of control centre.
The anti-alarm method that knocks into the back is described below in detail:
Driver, before subway starts, starts this device, and inputs the vehicle operating information data such as traffic route, departure time-table by inputting display device 4. This device, in subway driving process, utilizes different transmitting powers to launch the signal of different frequency in real time towards periphery by signal projector 1. The frequency signal launched includes the vehicle operating information data such as the traffic route of this car, departure time-table.
After the signal receiver 2 of another car receives this signal, then the signal received is transferred to the data-analyzing machine 3 of this car. The corresponding coverage of each frequency values, the distance that the data-analyzing machine 3 of this car can calculate between vehicle and this car of launching signal according to the coverage of the frequency values received is how many, and by the display on input display device 4 in real time of this result of calculation, to remind driver.Simultaneously, the frequency signal launched includes the vehicle operating information data such as the traffic route of vehicle, departure time-table, according to these information, namely the vehicle receiving signal can determine whether that Ben Che and the vehicle launching signal are to travel in the same direction or backward going and be at the front of this car or rear, and then judge whether two cars knock into the back possibility.
If data-analyzing machine 3 judges that the vehicle launching signal travels in the same direction with this car, and the frequency coverage launched within the scope of the risk distance being likely to result in rear-end collision time, namely when two spacings are closely likely to cause rear-end collision excessively, alarm is sent to control centre by the mode of note, simultaneously, data-analyzing machine 3 can also calculate the safe driving proposed projects of the best, accelerate including needs, or slow down, or " face and stop " etc. beyond the safe distance of front truck, result of calculation and suggestion are shown on input display device 4, driver drives according to suggestion.
As it has been described above, plan content given in conjunction with the accompanying drawings and embodiments, it is possible to derive similar technical scheme. In every case it is the content without departing from technical solution of the present invention, according to any simple modification, equivalent variations and modification that above example is made by the technical spirit of the present invention, all still falls within the scope of technical solution of the present invention.
