Abstract
The invention provides a dual-frequency responder system which comprises a ground dual-frequency responder, a vehicle-mounted dual-frequency responder reader, a vehicle-mounted antenna and affiliated equipment thereof, and a vehicle-mounted power supply. By using the dual-frequency responder system, the problem of backup redundancy of the responder can be solved.
Description
Technical field
The invention belongs to track traffic information engineering and control field, particularly a kind of double frequency transponder technology.
Background technology
Along with train running speed improves constantly; Only rely on the mode of inaccessible information being delivered to mobile unit by track circuit; Aspect amount of information, can not satisfy the requirement that train safe is run at high speed, needing to increase transponder device provides a large amount of fix informations and variable information to mobile unit.
In Chinese train operation control system CTCS technical specification general provisions, all to use transponder device to the CTCS-4 level from the CTCS-1 level.Therefore, transponder is an indispensable equipment in railway Line of Existing Railway and the Line for Passenger Transportation.
Transponder utilizes electromagnetic induction principle, is used for realizing in the locality equipment of high speed point type transfer of data between ground and mobile unit.
Transponder is installed on the two rails center, is in resting state at ordinary times, only depends on the power of instantaneous reception car antenna and works, and can when receiving car antenna power, send coded message to car antenna.Be installed on the continuous transmitted power earthward of car antenna of locomotive bottom and when locomotive passes through ground transponder, receive coded message from transponder.
When train process transponder top; After transponder receives the car antenna electromagnetic energy emitted; Convert thereof into electric energy; Make the electronic circuit work in the transponder, send the 1023 bit data messages circulation that is stored in the transponder, until electric energy disappearance (being that car antenna is left away).
Carrier frequency: car → ground: 27.095MHz ± 5KHz; Ground → car: 4.234MHz ± 200KHz
Amount of information: message code length: 1023 bit; Available code length: 830 bit
Summary of the invention
The technical problem that the present invention solved is to provide a kind of double frequency transponder technology.
Realize that the object of the invention technical solution is: the double frequency transponder technology, comprise that two covers are independent fully, the different transponder circuit of operating frequency is encapsulated in the transponder shell separately.
This said double frequency transponder technology; Two cover circuit adopt the different working frequency in the transponder shell; Work alone simultaneously, vehicle-mounted transponder adopts different frequency to read the message of two different frequencies that the double frequency transponder sends simultaneously, two message datas redundancy that backups each other.
Principle of the present invention is: the present invention sends the energy signal of two different frequencies through vehicle-mounted transponder; Activate two in the double frequency transponder respectively and overlap the different transponder circuit of frequency separately that works alone fully, the two cover circuit that are activated send message to vehicle-mounted transponder respectively.
The present invention compared with prior art, its remarkable advantage is: 1) the present invention adopts an encapsulation, two the cover circuit, do not increase encapsulation, construction, installation, maintenance cost; 2) two message datas of double frequency transponder of the present invention redundancy that backups each other; 3) the present invention adopts vehicle-mounted double frequency to receive redundancy, has overcome the vehicle-mounted problem that does not have redundancy of prior art.
Below in conjunction with accompanying drawing the present invention is described in further detail.
Description of drawings
Fig. 1 has transponder working condition sketch map now.
Fig. 2 double frequency transponder working condition sketch map.
Embodiment
In conjunction with Fig. 1, existing usually transponder working condition is, the car antenna that is installed on the locomotive bottom is transmitted power 27.095MHz ± 5KHz earthward constantly; And receive coded message when the ground transponder from transponder at locomotive.
When train process transponder top; After transponder receives car antenna electromagnetic energy emitted 27.095MHz ± 5KHz; Convert thereof into electric energy; Make the electronic circuit work in the transponder, send 4.234MHz ± 200KHz message code length 1023 bit to the 1023 bit data messages circulation that is stored in the transponder; Available code length 830 bit are until electric energy disappearance (being that car antenna is left away).
In conjunction with Fig. 2, double frequency transponder situation and existing transponder working condition are similar, and difference is that existing transponder has only a pair of car ground/ground turner working frequency, carrier frequency: car → ground: 27.095MHz ± 5KHz when working; Ground → car: 4.234MHz ± 200KHz.
And the work of double frequency transponder the time has two pairs of car ground/ground turner working frequency,
Passage 1 carrier frequency: car → ground: 27.045MHz ± 5KHz; Ground → car: 3.634MHz ± 200KHz;
Passage 2 carrier frequency: car → ground: 27.145MHz ± 5KHz; Ground → car: 4.634MHz ± 200KHz.
The message of two passages backups each other, message code length 1023 bit; Available code length 830 bit.
Claims (2)
1. a double frequency responder system is characterized in that, is included in to have the two cover different transponder circuit of frequency that work alone fully in each double frequency transponder, is encapsulated in the transponder shell.
2. a double frequency responder system is characterized in that, this said double frequency responder system, and vehicle-mounted transponder also adopts fully independently circuit of two covers, reads the message of double frequency transponder respective frequencies respectively.
