Description of drawings
The schematic diagram that Fig. 1 is connected with mobile unit and row control central apparatus for transponder ground installation of the present invention.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer,, technical scheme of the present invention is clearly and completely described below in conjunction with accompanying drawing.
The schematic diagram that Fig. 1 is connected with mobile unit and row control central apparatus for transponder ground installation of the present invention.As shown in Figure 1, this transponder ground installation 20 comprises:
A plurality of (only illustrating one among Fig. 1) passive balise 21 is used to send the fixed data information of self storing;
A plurality of (only illustrating one among Fig. 1) active balise 22 is used to send real time data information;
LEU (LEU) 23 is connected with active balise 22, and is connected with row control central apparatus 10, is used for providing real time data information to active balise 22.
Wherein, passive balise 21 and active balise 22 are the high speed point type data transmission sets that adopt electromagnetic induction principle to constitute, and are used to realize the intercommunication mutually between ground and locomotive.Passive balise 21 and active balise 22 for example are installed on the sleeper at two one steel rail centers, when train process passive balise 21 and active balise 22 tops, after passive balise 21 and active balise 22 receive the car antenna institute electromagnetic energy emitted that is installed in the train bottom, convert electromagnetic energy to electric energy, drive inner electronic circuit and start working, send a large amount of coded messages to car antenna.Particularly, passive balise 21 sends himself data information stored to the car antenna circulation; Active balise 22 obtains real time data information and sends this real time data information to car antenna from LEU 23.After car antenna left passive balise 21 and active balise 22 tops, passive balise 21 and active balise 22 had lost power supply, just stop to send data message.
Interface fault between active transponder 22 and LEU 23, or active balise 22 is can not receive valid data information the time, active balise 22 sends the default data information of self storing, and the default data information of self storing to transmission by transmission real time data information translation, insert the sequence of 75 to 128 logical ones (or " 0 "), this mobile unit 30 that is applicable to that simultaneously active balise 22 is passed through activates and is ready for sending the situation of data message, and active balise 22 can not detect the situation of useful signal at input interface during mobile unit 30 passes through.
In case active balise 22 begins to send the default data information of self storing, as long as mobile unit 30 provides enough electromagnetic energies, even input interface has recovered useful signal, active balise 22 still continues to send the default data information of self storing.
Whether when transponder is activated by mobile unit 30 each time, it is effective all should to redefine input signal.
1) function one: transmitting uplink data.To mobile unit 30 data message transmissions, when car antenna during through the transponder top, transponder adopts frequency shift keying modulation FSK mode by passive balise 21 and active balise 22, circularly, continuously data are sent.FSK the key technical indexes and parameter adopt:
Centre frequency is 4.234MHz ± 175kHz;
Frequency deviation is 282.24kHz ± 7%;
Average transmission rate is 564.48kbit/s ± 2.5%;
When the data that will send were logical zero, corresponding transmission frequency was 4.234MHz-282.24kHz=3.951MHz; When the data that will send were logical one, corresponding transmission frequency was 4.234MHz+282.24kHz=4.516MHz.
2) function two: power to transponder.Provide working power by mobile unit 30 to transponder.The car antenna unit is that the continuous electric magnetic wave of 27.095MHz ± 5kHz produces magnetic field by continuous transmission frequency, provides energy to transponder, and transponder is responded to this magnetic field, and is converted into working power.
3) function three: the transponder programming.Be used for transponder is programmed, promptly data message writes and manufacturing data writes.
1) function one: the uplink data input.Import the data message that will send by LEU 23 to active balise 22, the signal of transmission adopts two-way differential level coding (DBPL coding) and baseband signal transmission means, signal amplitude is 14Vpp～18Vpp, and the transmission bit rate is 564.48kbit/s ± 200ppm
2) function two: the input of transponder interface power supply.Provide power supply by LEU 23 to the circuit of active balise 22 input interfaces part, the signal of transmission is sinusoidal wave, and frequency is 8.820kHz ± 0.1kHz, and signal amplitude is 20Vpp～23Vpp.
LEU 23 is data acquisition and processing unit, be connected with row control central apparatus 10 by serial communication interface or other interface modes, also can be connected with other equipment of ground, receive the data message or the state information of the real-time change of ground installation transmission, to send to active balise 22 continuously from self data information stored of the real time data information of row controls central apparatus 10 or corresponding input information state.And LEU 23 can send different separately real time data information to a plurality of active balises 22 simultaneously.
Interface fault between ground electronic unit 23 and row control central apparatus 10, or LEU 23 is can not receive valid data information the time, LEU 23 sends the default data information of self storing, and, insert the sequence of 75 to 128 logical ones (or " 0 ") by sending the real time data information translation to sending the default data information of self storing.
When the real time data information that sends when the ground electronic unit changes, between new, legacy data information, insert the sequence of 75 to 128 logical ones (or " 0 ").
LEU 23 is except that having the control interface with active balise 22, and between the row control central apparatus 10 interface arranged, and this interface can be that RS-422, RS-485, Ethernet, other bus modes or relay input mode connect.
According to the transponder ground installation of the foregoing description, can send corresponding data information exactly according to the demand of mobile unit on the one hand; On the other hand, owing to comprise a plurality of transponders, make mobile unit through this a plurality of transponder the time, the sequencing of the data message that can send according to the transponder that receives is judged the traffic direction of train, and promptly forward moves or inverted running; Again on the one hand, also make mobile unit to proofread and correct traveling error, thereby improve the car controlling precision, realized safe car controlling by the data message that transponder sends.
According to the transponder ground installation that the foregoing description provides, can send but be not limited to following information:
1) signal data;
