Description of drawings
Fig. 1 is that the rail of the regenerative resource power supply such as solar power of the present invention is handed over train-ground communication device sketch.
The specific embodiment
Fig. 1 is the system schematic of apparatus of the present invention.Among the figure, charging-discharging controller (5) and electric storage means (6) all are installed in the cabinet of other electronic unit LEU (1), mobile communication transceiver antenna (3) and solar panel (4) also stretch out in the cabinet upper end, there is cable outlet the cabinet lower end, by a transmission cable (7), be connected to train responser (2).
The cabinet of the other electronic unit in road (1) can be installed in orbit the ground surface platform, also can install on the little pylon in orbit.When selecting the place of erection, should avoid the shade of tree shade and building, there is enough illumination to produce electric energy with the generating body (4) that guarantees solar panel and so on, makes whole device have enough electric energy storages for electric storage means (6) in night and the rainy weather device enough reserve power supply regular power work to be arranged.Installing simultaneously should be solid and reliable, and airflow is impacted when avoiding the train high-speed cruising, and the Falling that may cause device falls to damaging, even the injection district affects train safe.
Three kinds of different communication modes that this device relates between the transmitting-receiving body are:
1, communicate by letter (the long distance high capacity communication) at this device and railway trains traffic control center;
2, communicate by letter (communication of low coverage low capacity and the long distance high capacity communication) of train on this device and the circuit;
3, by this device, on railway trains traffic control center and the circuit communicate by letter (forwarding is communicated by letter) of train.
As for not passing through this device, the direct communication of train on railway trains operation control center and the circuit is not in definite operating range of this device.
This device has a unique address code to distinguish with same device, code whereby, and railway trains operation control center could communicate by letter with it with train and be identified and calibrate.Below describe three kinds of different communication modes in detail:
1, the signal of communication at this device and railway trains traffic control center (TDC) is only sent by antenna (3), signal of communication can directly send to railway trains traffic control center, also can send to railway trains traffic control center as intermediary by the base station (BS) of GSM-R universal mobile communications, signal path is determined by GSM-R.For the function that detects at any time this device whether normal, device is in railway trains traffic control center monitoring constantly, namely by railway trains traffic control center at predefined time gap, regularly constantly send request signal to this device, after this device is received request signal, automatically reply immediately a normal operation signal, if lose continuously several return signals, then railway trains traffic control center should be judged as this place's communicator inefficacy, and show certain the calibration fault, the field repair of must dispatching officers immediately.Obviously, the fault of discontinuous several individual device on the circuit can't cause obvious potential safety hazard immediately to train operation, because communication function can be transferred to contiguous normal appts, only minuses at the most several measurement calibrations.
2, the two kinds of approach of having communicated by letter of train on this device and the circuit---closely low capacity communication and remote high capacity communication, the former realizes by train responser (2), the communication distance of train responser (2) is very short, generally in several meters scopes, only when train advances to responser (2) top, train responser (2) just may be coupled with the induction antenna of train bottom and receive and send messages, pass through wireless coupling, responser (2) mails to train with the address code of oneself, be equivalent to inform the train present position, train just can correctly be located; Meanwhile, train responser (2) also receives the code of train, then by antenna (3) code and elapsed time of this train sent to railway trains traffic control center (TDC), be equivalent to inform the information of railway trains traffic control center " this train has arrived at this terrestrial reference ".
And remote high capacity communication to be antenna (3) by this device realize, this device is received and dispatched more detailed information by antenna (3) to train, the information of the position of other train, speed, acceleration/accel before and after the circuit at that time for example, circuit situation information, station situation information etc. also has train to need information or the out of Memory of earthward train operation dispatch manage system center (TDC) transmission.Certainly, if possible, some information urgent, that quantity of information is little also can pass through responser (2) such as the information of the position of two row trains before and after the circuit at that time, speed, acceleration/accel etc. and receive and dispatch.That is to say that this device and train communication both can pass through train responser (2), also can pass through antenna (3) sending and receiving.
3; by this device; communicate by letter (the transmitting communication) of train on railway trains traffic control center (TDC) and the circuit is provided; it is a redundant channel; both can transmit the information in above-mentioned the 2nd joint; also can be the information of making station control or emergency handling; a kind of redundancy communication approach in fact also is provided; at the direct communication mal of railway trains traffic control center and train or by in the situation about neglecting; or find AT STATION emergency situation; must send the intervention schedule instruction to the train operator immediately, or have emergency situation need to send to the station alternate communication channels of meeting an urgent need when asking on the train.
Train responser (2) approximately arranges a train responser (2) every a fixing distance along track laying, if necessary in the main line setting, perhaps all arranges on the circuit.Because the communication distance by train responser (2) only has several meters, thus can only be when the railway division of train process train responser (2) top, ability and train communication, this is conducive to the accurate location of train.Because each train responser (2) has a unique code to be called geocoding, and train itself also has a unique code, be called the train coding.Responser code, train code, station code, railway trains traffic control center code have consisted of the address code that information sends between different transmitting-receiving communication bodies, and communication is carried out in order.
The train operation dispatch manage system center can with each train on the administration line with and position, speed, the acceleration value of the altogether three row trains of front and back two row trains, send to this train by base station or this device, the driver has just had clearly judgement to position, speed, the acceleration/accel of each rows of car before and after Ben Che and the Ben Che, can avoid the collision of knocking into the back, also can realize automatic Pilot by the on-board running system.
By this device, railway trains traffic control center also can with the communicating by letter of train on the circuit, as for the direct communication of railway trains traffic control center and train, in the operating range that this device is determined, do not explain.
The other electronic unit (1) in road in this device, can be only to carry out the simply dealt electronic communication device of passing by on one's way to receiving and sending messages, can be micro controller system or single treater, also can adopt the redundancy structure of dual processor to improve device reliability, and adopt two of four-processor to take advantage of two to get two redundancy structures, can obtain higher reliability.
The generating body of solar panel and so on (4) can be the device that can export electric energy under sunlight illumination, is also referred to as the PV battery, and the variety classeses such as silicon single crystal PV, policrystalline silicon PV, amorphized silicon PV, alloy PV, organic PV or film PV are arranged.In the not abundant area of sunlight, also can adopt aerogenerator to replace or the Partial Replacement solar panel, consist of the device of aerogenerator power supply or wind light mutual complementing power supply, aerogenerator is the indirect utilization solar power, does not conflict with title of the present invention.But the reliability of aerogenerator is relatively poor, and installation requirement is relatively harsher, and in a single day wind turbine or fan blade are blown off by strong wind, very easily threaten safe train operation, should weigh the advantages and disadvantages, do special design and construction before installing.Because this device most of the time all is in low-power standby state, frequently information exchange is only arranged within the short time of train process, so the device overall power is little, average power is very little, the volume size of solar panel is less, price can be very not high.
Certainly, any rail that is different from other contained type of the present invention is handed over the train-ground communication device, as long as adopt the generating body (4) of solar panel of the present invention and so on, no matter be solar electrical energy generation, wind-power electricity generation or wind light mutual complementing power generation, and no matter adopt the rail of any type to hand over the train-ground communication device, all have positive social effect and economic value, all in effective interest field of the present invention.
The electric energy that charging-discharging controller (5) can make the generating body (4) of solar panel and so on send efficiently, reasonably leaves in the electric storage means (6), a kind of electronic controller or digital controller, because the price comparison of solar panel is expensive, so how farthest to utilize solar panel, it is one of mission critical of charging-discharging controller (5); In addition, controller is protected storage battery in addition, avoids energy source from the overcharging of regenerative resource, and the task of the over discharge that causes of load running, the life-span and the safety that improve electric storage means; Overcharge, cross put, reversal connection, overload, short circuit, lightning strike protection etc. all are the functional tasks of controller.Structure, the function of charging-discharging controller (5) should according to different generating bodies (4), design and produce corresponding charging-discharging controller (5).
In the electric storage means (6), the most frequently used is storage battery, device of the present invention can adopt any suitable storage battery, can be closed type acidity or alkaline secondary cell, for example lead-acid storage battery or cadmium-nickel storage battery also can be the chargeable batteries of metal hydride nickel storage battery, iron-nickel storage battery, zinc-silver battery, zinc-nickel storage battery, lithium-ions battery, lithium polymer storage battery or other kind.For a small amount of gas-liquid leakage that prevents that storage battery from still may have, may produce corrosion to other device in the casing; Perhaps, also some storage battery is subjected to the restriction of ambient operating temperature and other environmental conditions, storage battery is not suitable for leaving in the electronic cabinet, may consider that more the battery age phase is shorter, need periodic replacement or take out charging, also storage battery can be placed in nearby other position of other electronic unit (1), be convenient to connect with short cable.Building circuit nearby AT STATION can be considered electric storage means (6) even the other electronic unit in whole road (1) are installed in indoor, but generating body this moment (4) should be able to touch natural energy resources can obtain electric energy.
Certainly, replace storage battery with ultracapacitor, device lifetime, efficient, reliability will have very large lifting, super energy-storage capacitor is subjected to the degree of the environmental concernss such as temperature also little than storage battery, do not have again the gas-liquid leakage problem, be well suited for this device, but at present price comparison is high, fortunately the delivery of this device is smaller, so in fact as cost of price or the acceptable of the ultracapacitor of energy storage component.
Electric storage means (6) can also adopt the flywheel energy storage device.In the generating body (4) that adopts aerogenerator or wind light mutual complementing power generation, the effect of flywheel energy storage device is relatively good.
Transmission cable (7) is used for the power supply from road side electronic unit (1) to train responser (2), and the communication between the two.If realize the standard Installation Modes of this device on the railway, the product of transmission cable (7), the other electronic unit (1) in road and train responser (2) in a single day becomes standard configuration, can in factory's batch production process, realize being tightly connected between the three, be three in one, adopt factory's encapsulating structure.
This device is laid very convenient simple and direct in the Railway Site integral installation, before the installation, device with three of one takes out from commodity packaging first, train responser (2) is inserted interorbital to be fixed, then attached cable, be fixed on the mounting after at last solar panel being inserted other electronic unit (1) and line, charge the debugging of to start shooting immediately such as electric storage means (6).
A kind of like this mounting process had both reduced construction cost, and the water, the gas cut that device are possessed resist in the natural environment are attacked, and the adaptive capacity of enhancing equipment in extreme climate environment is to the larger effect of train operating safety performance.Reflect according to industry, because signal device is struck by lightning, the hidden danger that cable construction quality, maintaining deficiency produce, perhaps because the extreme climate environment impact, cause very easily on the line signal fault and temporary term stop, even excite the traffic safety accident, this equipment safety property is high, be subject to again signal system and constantly monitor, highly beneficial to safe train operation.
Clearly, the cost ratio leaky cable of transmission cable (7) is low, and length is farther less than original leaky cable, so the cable cost of this device, cable installation and maintenance cost are low more than original cable, larger preceence is arranged economically.
