Abstract
The utility model provides a double-frequency responder system, comprising a ground double-frequency responder, a vehicle-mounted double-frequency responder reader, a vehicle-mounted antenna and an auxiliary device and a vehicle-mounted power supply. The double-frequency responder system can solve a problem of responder backup redundancy.
Description
Technical field
The invention belongs to track traffic information engineering and control field, particularly a kind of double frequency responder system.
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, can not satisfy the requirement that train safe is run at high speed aspect amount of information, needing to increase transponder device provides a large amount of fix informations and variable information to mobile unit.
In Train operation control system CTCS technical specification general provisions, all to use transponder device from the CTCS-1 level to the CTCS-4 level.Therefore, transponder is indispensable equipment in Existing Railway Line speed-raising 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 at ordinary times resting state, only depends on the power of instantaneous reception car antenna and works, and can send coded message to car antenna when receiving car antenna power.The car antenna that is installed on locomotive bottom is transmitted power and receive coded message from transponder during by ground transponder at locomotive earthward constantly.
When train process transponder top, after transponder receives the electromagnetic energy of car antenna emission, convert thereof into electric energy, make the electronic circuit work in the transponder, the 1023 bit data message cycles that are stored in the transponder are sent, until electric energy disappears (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
The utility model content
Technical problem solved by the invention is to provide a kind of double frequency responder system.
Realize that the object of the invention technical solution is: the double frequency responder system, comprise that two covers are fully independent, the different transponder circuit of operating frequency is encapsulated in the transponder shell separately.
This described double frequency responder system, two cover circuit adopt different operating frequencies in the transponder shell, work alone simultaneously, vehicle-mounted transponder adopts different frequency to read simultaneously the message of two different frequencies that the double frequency transponder sends, 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 by vehicle-mounted transponder, activate respectively two in the double frequency transponder and overlap the separately different transponder circuit of frequency 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 schematic diagram now.
Fig. 2 double frequency transponder working condition schematic diagram.
Embodiment
In conjunction with Fig. 1, existing transponder working condition is usually, and the car antenna that is installed on the locomotive bottom is transmitted power 27.095MHz ± 5KHz earthward constantly; And receive coded message from transponder when the ground transponder at locomotive.
When train process transponder top, after transponder receives the electromagnetic energy 27.095MHz ± 5KHz of car antenna emission, convert thereof into electric energy, make the electronic circuit work in the transponder, the 1023 bit data message cycles that are stored in the transponder are sent 4.234MHz ± 200KHz message code length 1023 bit; Available code length 830 bit are until electric energy disappears (being that car antenna is left away).
In conjunction with Fig. 2, double frequency transponder situation and existing transponder working condition are similar, only have a pair of car ground/ground turner working frequency, carrier frequency: car → ground: 27.095MHz ± 5KHz when difference is existing transponder work; Ground → car: 4.234MHz ± 200KHz.
And, there is two pairs of car ground/ground turner working frequency in double frequency transponder when work,
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 described double frequency responder system, and vehicle-mounted transponder also adopts fully independently circuit of two covers, reads respectively the message of double frequency transponder respective frequencies.
