Technical field

The present invention relates to a kind of communication system according to claim 1 preamble.

The present invention is especially applicable to delivery vehicle.What it should be understood that described delivery vehicle relates to is various forms of transport, especially the delivery vehicle of passenger and/or commodity transport field.Thus for instance, in scope of the present invention, not only comprised rail transport, for example track train and compartment thereof, tramway, but also comprise the pneumatic tire train or do not have with track, or there is the bus of at least one Special house.In addition, related can also be other conveying arrangements beyond bank base field, for example " ferryboat " this class sea service of shuttling back and forth.Especially, all these delivery vehicles all comprise to be controlled or command device, and be referred to as hereinafter " controller ", this controller can be set up or fill order application, can use it for guiding delivery vehicle thus, if delivery vehicle does not have driver, it even can control this delivery vehicle automatically so.It should be understood that numerous other application also can realize, but for the sake of clarity, do not enumerate these application here.

Background technology

Thus, from the first angle of vehicle interior, the communication network between at least two communication interfaces is known, and wherein this interface is connected with the first controller of foundation order application and the second controller of fill order application respectively.For example, this controller can comprise one or more car-mounted computer, and in this example, these computers are delivered by delivery vehicle.For each controller, these communication interfaces have at least one communication port being connected with communication links such as conventional Ethernet, ADSL, WiFi, to can carry out transmission information via the communication interface of the types such as modulator-demodulator, switch, bridge joint repeater between controller.The in the situation that of breaking down on point-to-point link, for example can set up redundant link by increasing the mode of transmission line or cable and so on, wherein said transmission line be by changing switch, router activates into new data route by reconfiguring the means of router and so on, and described router self is with the consultative management of internet/ethernet type.

From another angle of delivery vehicle outside, information can be sent to the second communication interface of delivery vehicle delivery from ground the first communication interface, and vice versa, and wherein said the first communication port can be positioned on delivery vehicle route.Amplification is come, and the first communication interface can also or be linked to be with it " subnet " with ground third communication interface networking, for example, be connected to the access point on center service managing server or other delivery vehicle.In brief, here be readily appreciated that, for the communication system adapting with delivery vehicle, the communication system on vehicle interior, ground and between delivery vehicle and ground namely, this communication system has comprised complicated network, the framework of its network link is multipoint type, and Data Transport Protocol likely can change according to desired application.

EP1533913A1 provides an effective example, the complexity of the communication network between the network of the clear track train being connected with electric power suspension wire of this example table and for example, " IP network " in train exterior (ground) (IP=" Internet Protocol ") type.For making the communication interface of IP network, can communicate by letter with the communication interface (" end user ") of delivery vehicle delivery, at track, placed data converter along the line, so that the data transaction that will transmit or receive according to " IP " form becomes the form of " PLC " (=" power line carrier communication ") type.For example, described data are sent to transducer, to output to the communication interface on train with PLC form via electric power suspension wire.In order to obtain necessary electric power on suspension wire, this transducer has comprised in track some converting units along the line.In French, the communication technology of " PLC " type is also referred to as CPL (=Courants Porteurs en Ligne: circuit carrier communication), especially, in this example, this communication technology can be for high information flow-rate data provide enough bandwidth in the IP network being connected with train, vice versa (amphicheirality that can transmit), and thus, ground-train communication that this communication technology can be used to the train of different length to implement is also adaptive with it.In addition, transducer used is also associated with the retransmission unit (" repeatingmeans ") of reception or transmitting data, and its signal has been divided in predetermined band, to determine the transmission direction (two-way) of the data between IP network and train.If certain part distance does not comprise suspension wire (cat é naire), activate a CPL type communication switchboard being connected with radio frequency type communication switchboard, to radio link is provided, the direction that wherein data-driven transmits, this radio link is double frequency equally.Thus, if one of them link cannot be used, CPL type link and radio frequency type link will form redundant link so.In brief, for having the single-link of advantages of redundancy between train and ground network, what use is two kinds of dissimilar communications, need to switch thus aspect equipment, particularly on the output port of communication interface, add extra route device, to select CPL or radio-frequency channel.This processing also need to change router and data routing configuration according to communication protocol used, and on the one hand, this change has involved IP network, and on the other hand, this change has also involved delivery vehicle.Current, thisly relate to the time of reconfiguring of new route more than needing the several seconds, thus for instance, if break down, the so described time will exceed needed 3 seconds tolerance limits of some rail transport automatic controller.

Conventionally, the application that relates to control/command process is used often in transportation, especially unpiloted automation city this class automatic transportation of train.As described in, the controller that comprises one or more computer and relevant interface has been used in these application.According to its function, these controllers both can be positioned on delivery vehicle track ground along the line, also can be delivered by one or more delivery vehicles, and wherein said delivery vehicle both can be coupled by (some trains), also can not be coupled.In order, at track monitoring and controlling train along the line, to connect by one or more networks (link, suspension wire, track etc. in the air) between these different controllers self.

Thus, on the whole, the framework of control/command process network likely can overcomplicated, and likely can produce high equipment cost.

This each network is wherein also likely very long, and (delivery is approximately 300 meters ON TRAINS.Track length along the line reaches several kilometers), and will suffer from severe electromagnetic environment.

In addition,, concerning this some network wherein, the link that set up is that multiple spot connects, and does like this and has improved route complexity, especially true when origination point arrives point failure.

Except these various boundary conditions, also must guarantee that train correctly works here: do not stop in good time or occur that other problem fault is all undesirable for the business efficiency of passenger, train and even passenger safety.

Thus, for the suitable communication system (in vehicle interior or outside) of delivery vehicle, be necessary to solve following technical problem:

On the one hand, except some constraints for communication network physical layer, when guaranteeing high-transmission quality, (low error rate) also will provide high data message flow (for example available information flow of 10Mbit/s).

Give an example, electromagnetic environment on train is very strong, and the network that forms link between different controllers likely can be subject to the upset of multiple severe jamming, in the situation that networked physics layer has been used quality to be unsuitable for the cable (5 classes or 6 class cables) that directly uses is especially true.Equally, concerning the equipment of train delivery, network configuration can develop, the train length that especially described network must be compatible scalable (train that quantity can change, for example, after coupling).Thus, fast simply (automatically) to reconfigure complex communication system be very important, for example, when train length doubles.

On the other hand, except complexity, also must guarantee the high availability of communication here, so that system can " transparent " be stood fault securely, especially the work that needs the simple fault that relates to communication system (inner delivery vehicle network, outside ground network and delivery vehicle-terrestrial links) preventing or certain equipment being connected to affect control/command system.

Therefore,, in order to stand fault, people tend to copy command system, especially, network and controller are that the form of matching forms, thus, as document EP1533913A1 indication, if broken down, we can be by switching and replace another between RLC link and radio frequency link so.

But in fact this switching is the possible redundancy of equipment, for it, the peculiar problem of some network is to solve:

A), as briefly having discussed, control/command facility can suffer from severe time-constrain.Give an example, if broken down, the work that some rail transport auto-mechanism can be tolerated about 3 seconds at the most is so interrupted.This time is smaller than the setup time again of " the 3rd layer " router (major part of physical network layer), and this router needs the more time with other router, to change the network router breaking down.

B), if the equipment being connected with consolidated network or computer are a lot, copy described in so and likely can be difficult to management.

C) in addition, network faults itself exists the risk that simultaneously affects several controllers or computer, and therefore, this fault is even more serious.Equally, the individual equipment in network or the fault effects in communication interface also should be avoided to the situation of other equipment or interface.

D) concerning the network of delivery vehicle delivery, need to remember, its configuration likely changes, in fact, and the necessary compatible train length of these networks, and train length can change according to compartment/vehicle fleet size.In addition,, for network redundancy, this concrete constraint also need to be taken into account.

By the problem of considering that these are different, it is contemplated that out some solutions hereinafter, but still existing the present invention, these solutions are intended to some defect solving.

First, when guaranteeing high-transmission quality, especially in adverse circumstances, (there is strong switching current), want to allow communication system (network) can in very long length, have very high flow rate (for example can use at least information flow-rate of 10Mbit/s in 300 meters of length), it is known having several solution:

A solution is to use optical fiber for the link between communication interface, but this solution is unthinkable in some cases, give an example, this technology is difficult to use ON TRAINS, for example, the Cuccia coupler concerning between two of the train that will be coupled unit (compartment) especially true, if described coupling is the trailer automatically carrying out, so this situation even can be more applicable.

Another kind of solution is to set up adsl link, but produced like this problem, especially, this type of link normally provides in order to set up point-to-point link, if be applied to multidrop network, this framework will be very complicated so, in addition, if there is the fault relevant to one of controller that is connected to adsl communication interface, unless set up so star-like distribution, otherwise this will all produce certain influence to whole network, but in this case, it is too various that the wiring being associated with network certainly will become.

A solution of current use is to use low information flow-rate link, yet very unfortunate, this control/command facility that is treated to has brought a lot of constraints.

Secondly, in order to tolerate fault, especially avoid the fault effects communication system work of certain network or certain relevant device, it is known having several solution:

The most conventional solution is to use two different redundant networks, but this solution needs high equipment cost.For example, according to each controller, comprise that two redundant computers are known, in order to realize high availability, every computer is preferably connected to two networks by different port (having thus a lot), and its message is sent to other controllers or the computer on each network in these two networks.

Another embodiment about this communication system is used loop network and redundant manipulator and computer is connected to difference " switch ".But this solution only require be correlated with " switch " can be in the situation that there is local fault via alternative path, resend fast the message technology of (for example according to " rapid spanning-tree " by name).Current universal this technology is applicable to the physical layer of " optical fiber " type very much, but in train and track equipment along the line, the cost of implementing this technology is very high.

Summary of the invention

The object of the invention is to propose a kind of communication system that is particularly suitable for delivery vehicle, this communication system is in vehicle interior thus, but expansion is come, it also can be outside in delivery vehicle, to be implemented in adaptive communicating by letter between delivery vehicle and ground network, or for torus network architecture individually, there is not prior art defect as above in this system.

First aspect of the present invention provides a general solution, and wherein this scheme is not taken delivery vehicle and/or ground into account with the visual angle of inner or outer portion communication system.

The invention describes a kind of delivery vehicle that is particularly suitable for, the communication system of the network infrastructure in other ground network architectures and even building, wherein this communication system comprises for example, communication network between at least two communication interfaces (modulator-demodulator), and described communication interface (is namely moved with management respectively, being actually foundation) first controller (for example having two redundant computers) of (for example guiding train) is applied in order and the second controller of management (namely operation) order application is connected, wherein said order application can be identical with applied by the application of the first controller management or operation or other those order that will move.For each controller, this communication interface has at least one communication port, guarantees thus between controller the communication link via its respective communication interface.

Very advantageously, in order to transmit order application between two communication interfaces, this communication link has adopted CPL type (power line communication), and comprised at least two electrically conductive links, wherein said electrically conductive links is connected to each respective communications port by least one coupling transformer.

Before continuing, should be borne in mind that in order to take power line as supporting to set up computer network, already designed at present CPL technology, thus, high information flow-rate link is to carry (alternating current [220V with energy source, 50Hz] or [110V, 60Hz]) parallel mode arranges.The advantage of selecting this technology is to realize the high information flow-rate link that physical characteristic is different from power line with unconventional support, thereby optimizes quality and the topologies that is suitable for CPL link of the present invention.

Equally, another benefit of CPL network is that it is multidrop network, and do not need to install capital equipment (if be by conventional dispersion protocol for the multiple access of transmission medium, for example CSMA---" multiple access access carrier is intercepted " manages), each work station (controller, computer, order/final controlling element " enduser " ... .) for example, as long as there is single adapter (Ethernet-CPL bridger) already enough.Similar to power network, each communication interface can with two CPL link parallel joins.Another advantage of this selection is that its tolerant network changes; Especially, at equipment, be connected with electrical network or during disconnection, characteristic likely can change.This can realize on the one hand automatic network and configure (for example, when after coupling or separated train delivery vehicle, train length being modified) again.This characteristic of the present invention can also prevent a plurality of communication failures on network.

Owing to having used CPL technology, on train, especially very long train, will guarantee to realize (it is between " transmitting/receiving " controller that expansion is come) between communication interface the transfer of data of high-transmission output.If certain wire breaks down, so as passive circuit components, the target of coupling transformer is to redefine two distribution of impedance between link, guarantees that all the time transfer of data is injury-free thus by CPL wire.Thus, no longer advantageously need hand-off process here, more specifically say and no longer need any " active " equipment or control with rerouting the equipment (for example " switch " or other data switching apparatus) being associated of processing.In addition, for redirect the time of data on the 2nd CPL link, be almost constant, the special time demand during having met thus that rail transport is in office and why hindering.On the other hand, from CPL link to another kind of communication link, the parallel or redundancy of (for example radio frequency, ADSL, WiFi, Ethernet etc.) is switched and will be avoided, do like this dynamic management complexity that will greatly reduce proposed communication system, and do not need to add the particular device with dissimilar communication link.Certainly, in order to improve fail safe, except two CPL links, can also add other links except CPL link here, but CPL link is the most firmly, concerning the transfer of data of the present invention's expection, this link has the highest performance.

Owing to there being two RLC links, therefore, between two communication interfaces, can realize physical transfer redundancy.In view of daily public transportation (intercity, train, tramway etc.) is used as transmitting suitable cable with track or track signal along the line, this dual link is universal and high-quality equally.This cable comprise at least two can be for the wire of CPL technology.In addition, for instance, by for example, for urban traffic signal, as well known to those skilled in the art and comprise the K23 type signaling network wiring of at least one pair of twisted-pair feeder and shielding, each circuit can comprise a pair of different electric conductor.This is particularly suitable for the purpose of the present invention, because it has guaranteed the fastness to anti-adverse environment, and the environment relevant from different mechanical condition for example.

The stacking power supply of DC network type can be in very low voltage (24V, 72V etc.), and these power supplys can be connected to wherein at least one CPL link equally.Especially, doing like this and can guarantee high data message flow, and can guarantee between communication interface to be the long-distance supply wall scroll of remote equipment twisted-pair feeder, for example, is very long train or track supply of equipment along the line.

In addition, in order to tackle the high availability problem of the computer network of quoting from prior art, especially in order to tolerate fault or failure, the present invention allows to use two redundant networks, but this processing is in the situation that attempt having two really different networks and realize, and thus will 100% double.Therefore, embodiments of the present invention are more flexible, and need to aspect equipment, significantly reduce, because link is doubled is only to comprise adding single coupling transformer, rather than add new communication interface or new modulator-demodulator.

Meanwhile, re-set target just guarantees that network self has high availability, and on network, places redundant manipulator and can satisfy the demand, and does not need to manage a plurality of Ethernets path.

For this purpose, the Fault Tolerance of communication system depends on the definition of new principle, and wherein this is defined as follows: according to the present invention, each redundant manipulator is connected with single CPL (power line) network, but its physical layer will double.Especially, what this support comprised is not that single " copper cash " is right, but parallel two " copper cash " is right.

Concerning solution described in the prior, in order to obtain very high availability, each controller of these solution requirements is preferably connected with two networks by different port, and need thus the modulator-demodulator that quantity is a lot (each controller has two), the invention has the advantages that it can be by modulator-demodulator quantity divided by 2.It comprises that two " copper cash " that each CPL modulator-demodulator (communication interface with coupling transformer) is connected on network are right, and are no longer connected to single line pair via very simple circuit.Thus, concerning each network connects, two lines of this of network to or CPL circuit be parallel join, and can follow different transmission channels according to its position or its function.

For example, the CPL link between different CPL modulator-demodulators can be used a large amount of frequencys modulated carrier, and these links comprise two pairs of wires, can implement to depend on thus the transfer of data of wire impedance.

If certain line of network is right/link occurs fault, for example short circuit or open circuit, this will cause impedance to change so, and the data that transmit on different carrier distribute and are modified, to keep circuit according to the high tolerance limit of the physical layer of CPL technology.Upper at the network connection point (except communication port) that is positioned at CPL interface, these two networks, to being parallel join, have still been taked precautionary measures here.Especially, what the present invention planned is an independent dual link equipment, and guarantee two lines between coupling enough weak, in order to avoid line is to upper short circuit or interrupt disturbing or significantly weakening the signal being present in other pairings simultaneously, especially in the place that approaches tie point.

Thus, the present invention supposes that coupling transformer has provided the distribution of impedance between CPL circuit, and so, if certain link breaks down because of interruption, short circuit, mechanic effect etc., other links will be guaranteed order application transport so.For this purpose, should be borne in mind that, CPL circuit be in the situation that needn't providing source current by wire to connecting, wherein said wire is to being preferably exclusively used in CPL technology, and in this exemplary case, do so further complexity and the quantity that has reduced the assembly that comprises communication system.

Physics and economic aspect all very significant one may characteristic be: if necessary, at least a portion of one of them RLC link is that the power supply of communication network element connects, and the power supply wiring that wherein this connection also can be used as compartment or train is installed.Certainly for adverse circumstances in the CPL cable that adapts of high information flow-rate, power supply wiring does not produce optimum cable association attributes, if but certain link does not need very high performance, it can be also possible alternative so.

Thus, provided the simple favourable coupling transformer of several forms here, and can improve the CPL link couples with communication interface.

If necessary, can also provide the equipment interrupting in communication generation problem for avoiding here, wherein this equipment can be the control, compensation of communication system and from surveillance.

All aspects of the invention of addressing thus provide a general solution, and the viewpoint that this solution is not taken communication system into account is in vehicle interior or outside.

Especially, the present invention is a very favourable solution, and it has several communication system configuration more specifically:

1) this communication system is inner Vehicular communication system: for example, at delivery vehicle, can guide and deliver communication interface, controller and/or at least one CPL link on the public toter that maybe can not guide.CPL link is to extend along the length direction of delivery vehicle that comprises the public transport of train and so on, and this link is connected with the communication interface of expection.Thus, some delivery vehicles if be coupled, by middle CPL link its communication network that is coupled, wherein for instance, described coupling can complete by following mode: by the Cuccia coupler between delivery vehicle (for example, in Coupling device), by the power supply suspension wire of delivery vehicle, by delivery vehicle and contacting of at least one guide rail etc.In addition, it is also conceivable in the middle of other, connecting, but it does not fall in desired extent of the present invention.

2) this communication system is inner mobile unit, and it can be distributed in several different public transportation devices, in this case:

Between two communication interfaces, have at least a part of link to lay respectively at the first public transportation device and the second public transportation device,

Two public transportation devices are close to each other, but are physical separation in this example.

If lacked the torus network medially that can concentrate in together communicating by letter with each public transportation device or supplemented as it, other parts of link comprise suspension wire or the electric tracks (applicable transmission, known CPL type) between two public transportation devices so.

3) this communication system is ground network (also independent with it outside delivery vehicle), its at least one local subnet network is according to CPL type of the present invention, in addition, as described at the EP1533913A1 of prior art, the transmission of any type that the delivery vehicle in this network and motion carries out is suitable, wherein for instance, described adaptation can be undertaken by a part for radio frequency link (in the air) and even a part for CPL link, wherein said CPL link can comprise the channel of sharing public frequency, but if necessary, it also can comprise the channel with different frequency.Owing to having inserted coupling transformer at communication interface output, therefore, this ground network can be enjoyed the benefit that first forward part is described.So, by place simple coupling transformer on existing interface, can very advantageously avoid adding, particularly at channel, add a large amount of expensive equipment along the line.

More particularly, the ground communication interface connecting by CPL terrestrial links is all positioned at ground thus, preferably, it is along the line that this interface can be positioned at delivery vehicle track, in track ground communication network along the line, or the form that adopts track continuous sub-network along the line to troop, can carry out radio communication (preferably using WLAN type as nominal pattern) with the equipment of delivery vehicle delivery thus, preferably, described communication is to carry out via the redundance unit that comprises at least one vehicle-mounted redundant transmission/receiving router (with redundancy transmitted in both directions), two logic ports of the one or more routers that are for example connected by the physics CPL link with delivery vehicle.

According to the present invention, link between controller and communication interface thereof is preferably by producing with physical port vehicle-mounted and/or that be connected in the CPL on ground network, (each comprises IP address on this network, to have set up two logic ports, route data etc.), to advantageously obtain two logics and even the acquiescence physical communication gateway that deliver and/or be positioned at each different router on ground by delivery vehicle, thereby set up at any time at least two possible communication paths, for use in train and/or ground equipment.Thus, vehicle-carrying communication interface (and the one or more controllers that are associated) will guarantee to implement high information flow-rate transmission on these two gateways with two physical connections between ground two communication interfaces (and the one or more controllers that are associated), and has highly redundant availability between these two gateways.This processing is in the situation that do not add or replace new communication interface and realize.

Finally, if communication interface breaks down, for communication interface, from surveillance equipment, can in paid close attention to communication port, forbid the permanent transmission of electric current, voltage and interfering data so.

Dependent claims has also provided advantage of the present invention.

Embodiment

That Fig. 1 describes is the communication interface MOD1 that has been equipped with CPL " front end " communication port, wherein this port is connected with the electronics coupled transformer of RLC coupler, to guarantee, between communication interface MODl and CPL network, there are at least two physical link CPL, CPL2, give an example, described CPL link is mounted on the train being connected with other communication interface, but is not illustrated in the drawings.In this example, each link CPL1 or CPL2 comprise a pair of different electric conductor, and for example a bundle is for the cable of K23 type urban traffic signal, and described cable can comprise at least two pairs of twisted-pair feeders, and can comprise screen.The coupling transformer of CPL coupler produces distribution of impedance between link CPL1, CPL2, thus, for example, if one of them link (CPL1) or other link being attached thereto break down because of interruption, short circuit, mechanical effect etc., so for instance, another link (for example CPL2) will be guaranteed the transmission via the order application of communication interface MOD1 by CPU processor.In practice, this order application is by comprising that computer is (in order to ensure redundancy, also can comprise some computers) controller (not shown) management, and this Computers and Communication interface MOD1 is connected, for a simple example, this computer is by the Ethernet Et_line connection of link 10/100BT type and coupling element (the Et_coupler coupler of other ethernet types; Et_Port port) be connected with interface MOD1.

Certainly, it is also contemplated that other physical communication ports that are positioned at interface MOD1 here, for example, represent the port of RS232 type UART link connection or other Ethernets or CPL link.For the present invention, what recommend in principle is to use for itself being CPL network of network link or the conductor part/pairing (for example, together with delivery vehicle) that is exclusively used in CPL technology, but, between the controller of at least applying in order or actuator and command interface, still used existing part or the part of other type (if possible can very long or seldom not be exposed under upset).To be exclusively used in all links of CPL technology or wire concerning, the source current that CPL technology provides not is essential existence.Meanwhile, wherein at least a portion of certain link (CPL1, CPL2) can be arranged on delivery vehicle and connected for the power supply of communications network components.Furthermore, it should be noted that, disposed " CPL end " output of the CPL_coupler coupling transformer that is positioned at low decay (maximum is several decibels) attenuator here, wherein for instance, described deployment is to be undertaken by the resistance/impedance of the placement/distribution of connecting with two link CPL, CPL2.These processing have improved the quality of CPL_coupler coupling transformer, in this sense, can avoid unexpected short circuit to cut off all signals on two couples of conductor CPL1, CPL2 here, for example, occur in the short circuit of output of the coupling transformer of link CPL, CPL2.In communication interface, if do not satisfied the demand or unavailable by means of the distribution of impedance of the line matching resistor in communication interface, so this situation is also suitable for.In this sense, other solutions are also feasible:

For this purpose, coupling transformer produces enough continuous impedances, to prevent that partial short-circuit from cutting off the signal on these two networks,

The bridge joint twisted wire of CPL network (referring to the STUB in Fig. 3) has the minimum length of about 20cm, can in the situation that interface MOD1 or link CPL or CPL2 are short-circuited, guarantee enough impedances thus,

Equally, attenuator is different from adding, and we it is also contemplated that and use link matched resistor as the center series impedance conventionally existing in the communication interface MOD1 of modulator-demodulator and so on; Thus, as long as on this distribution of impedance each link in these two link CPL1, CPL2 of CPL network, be just enough to be offset this impedance.So,, by using CPL physical layer attributes, this characteristic of the present invention can realize a kind of simple architecture of tolerating fault for the CPL network of high availability.In addition, the advantage of this new architecture is all to have set up passive redundancy in every connection of vehicle interior network, and this processing normally vehicle-mounted CPL link of at least one pair of in the CPL link of settling along delivery vehicle realizes, wherein said delivery vehicle is connected with every a pair of link (CPL1 in Fig. 1, CPL2) on branch road position, and these two pairings CPL1, CPL2 of network are parallel joins.This solution does not need the dual connection of redundancy twisted-pair feeder, and this dual connection exists the dual shortcoming that the interface quantity of modulator-demodulator and so on is doubled and cause logic addressing (for example each controller has 2 IP addresses) complex management.Thus, concerning proposed technology, in its favourable example principles, take following is basis:

Take two parallel " copper cash " to being support

Permission to parallel join, is guaranteed enough low new equipments of the degree of coupling therebetween by each communication interface and two " copper cash " simultaneously.Aspect each communication interface, its object is no longer to have single link, but has two for the link of physical layer,

According to the present invention, it is all feasible that some embodiment arrange, but has only proposed to use the simplest solution of passive block here.

For example, the feasible scheme that the dual communication interface (MOD1) that a kind of and CPL network are connected is connected can be in the following way and by simple realization:

On the port of each the interface MOD1 being connected with one of link CPL, CPL2 respectively, at CPL_coupler coupling transformer place, use the 3rd absolute coil (to be for example positioned at the 3rd conductive coil of the bypass position of conventional transformer, wherein said bypass position comes from the conventional transformer with two coils)

On each the interface MOD1 being connected with one of link CPL1, CPL2 respectively, first settle the first output transformer, then settle the second output transformer,

Do not revise interface MOD1, but insert adapter circuit between interface MOD1 and two CPL network links.This adapter circuit can adopt this simple form of transformer (or equivalent designed of two transformers of use) with three absolute coils.

For communication interface being connected to the CPL network of the communication system suitable with CPL delivery vehicle, for other reasons, the present invention advises using separated transformer or coil, especially, do be like this for:

Prevent ground short circuit or other wires pair of other Effect of Short Circuits in certain couple of conductor,

Can in two pairs of wires, be added with the signal of telecommunication (for example, by means of overlay feed) or the different command signals that may there are differences.For this purpose, at least, a link in link CPL1, CPL2, the mode being here in series with the output winding with coupling transformer has been settled a capacitor, in order to avoid by low electronic frequency short circuit.In Fig. 1, this processing is shown in the output of CPL_coupler coupling transformer,

Can carry out supplementary copy invention by operational failure checkout equipment.For example, the target be here each wire on inject a continuous signal (curtage), to determine whether a wire these two wire centerings exists fault to inside.More put it briefly, communication interface MOD1, correlation control unit and/or one of link CPL1, CPL2 be placed on this wherein the fault monitoring module at least one assembly downstream be connected, for example be connected with direct current syringe or voltage generator, and wherein can measure its voltage or electric current the upstream of at least one assembly at this.

Equally, in each output with communication interface or the parallel position of CPL link/network, can add protection diode, for example parallel being placed according to the diode in every couple of conductor of Fig. 1.

In order to improve this solution, here can by add and set up for communication interface (modulator-demodulator) from monitoring mechanism, carry out supplementary copy invention, after breaking down, there is the potential modulator-demodulator disconnection automatically of continuous transmission thus.
