Definitions

  • the present invention relates to a system and method for automatically eliminating an excessive bias voltage in an energy bus via which distributed functional units located in an industrial plant are supplied with electrical energy.
  • Such decentralized functional units are used in particular in rail transport networks such as the railroad, where these are used to control vehicle influencing and / or vehicle monitoring units and to monitor functionality and to record process data and back to a central control and / or Monitoring center, such as a control center or a signal box, to report.
  • a central control and / or Monitoring center such as a control center or a signal box
  • As Switzerlandbeeinu units that give instructions to the driver or even make direct intervention in the vehicle control or directly set a safe track for example, signals, points, balises, line conductors, track magnets and the like, as well as sensors for detecting process variables of the moving train, such as power consumption, speed and the like.
  • train and track section monitoring units can also balise and line conductors, but also axle and track circuits and other train detection systems are called.
  • the present invention relates to all industrial plants in which functional units are distributed over long distances and yet must be centrally controlled.
  • the central controller can be perceived by a stationary control center, but also by
  • a digital data transport network be used, which is robust in any way against a simple fault event, yet a very skillful use of very widely used in railway engineering Cu cables, for example, previously available interlocking cables, allowed and finally only a relatively small number of network access points needed.
  • Such a device is used in a particularly advantageous manner for a rail network for rail transport. Consequently, it is then expedient, by means of the decentralized functional units traffic-monitoring and traffic-controlling functional units, in particular signals, switches, axle counter, track circuits, point and line train control elements to couple to the data transport network.
  • traffic-monitoring and traffic-controlling functional units in particular signals, switches, axle counter, track circuits, point and line train control elements to couple to the data transport network.
  • the supply of the connected consumers can take place from both supply sides. This creates a previously unavailable redundancy of the energy supply.
  • the decentralized functional units also known as element controllers or EC for short
  • EC element controllers
  • SNDs bus couplers
  • the SNDs can interrupt or bypass the power bus, as well as measure currents and voltages in the power bus.
  • the wires of the power bus which are arranged in the vicinity of the traction power supply (contact wire), are an influencing voltage due to the cable covering exposed.
  • the influencing ohmic, capacitive and / or inductive nature.
  • the inductive mode of influence is the dominant influence here and acts as a common-mode source which, in the case of potential-free cores, injects an equally large, in-phase interference signal with the frequency of the contact wire feed.
  • the present invention is therefore based on the object of specifying a system and a method for automatically eliminating an excessive influencing voltage in an energy bus, which provides decentralized functional units arranged in an industrial plant with electrical energy.
  • an influencing voltage in the power bus and / or a ground fault should be reliably and quickly detectable, so that immediate measures to restore the correct function of the power bus can be initiated.
  • the two feed points can draw their energy from two independent energy networks and feed them electrically isolated in the power bus.
  • the power bus is potential-free display and has due to the independence of the two energy networks on an extremely high availability.
  • the network node unit which opens a switch has previously been configured for this application. In this way, no communication among the network node units with each other is required, but it is enough alone the detection of excessive interference voltage and / or ground fault.
  • the network node unit thus determined can also carry out the bus disconnection if the power bus is in the state ground fault and, if necessary, additionally the influencing voltage also exceeds the corresponding limit value. This measurement can be left to this predetermined network node unit alone.
  • the network node unit opening a switch can be arranged in the region of the geographical center of the power bus. For example, in the event of a ground fault, it is possible to roughly halve the inductive effect of the contact wire on the power bus, so that twice as much distance can be achieved for the power bus. In addition, in the event of a ground fault, the risk to the maintenance staff can also be halved approximately.
  • a further advantageous embodiment of the invention which practically requires no communication between the network node units in this regard, can be achieved if each network node unit itself has the evaluation module.
  • FIG. 1 schematically shows an interlocking architecture with a system Sys, which has, inter alia, a signal box STW, a redunant degraded data backbone NB1, NB2, a data bus CB and an energy bus EB with two feed points PS1 and PS2.
  • the interlocking STW controls a train traffic on a track section G, in which signals S, points W, a level crossing Bue and axle counter AC are arranged.
  • These train protection and train control components each couple to a decentralized functional unit - also called element controller unit E - on the data bus CB and the power bus EB.
  • the decentralized functional units E are connected to the annular data bus CB in such a way that either access to the data backbone NB1 or NB2 is given via each side of the annular data bus CB.
  • the sequential connection of the Element Controller Unit E to the ring-shaped power bus EB ensures that each element Controller Unit E provides redundancy from both sides and therefore with the corresponding routers / switches SW electrical energy can be supplied.
  • FIG. 2 now shows schematically the data and power supply connection of the Element Controller Unit E of a train control component, here for example a switch W, to the data bus CB and the power bus EB.
  • a train control component here for example a switch W
  • Such an attachment point comprises a network node unit SND and the actual element controller EC.
  • the network node unit SND comprises a communication unit SCU for data exchange over both branches of the data bus CB.
  • the network node unit SND is designed so that it couples to both branches of the power bus EB and thus always, if necessary, across other network node units SND away - an access to both feed points PS1 and PS2 consists (as in FIG. 1 shown).
  • the network node unit SND further has a control and evaluation logic SL, which can be integrated, for example, in a switching module S, and thus controls and monitors the power bus EB.
  • the control and evaluation logic SL detects current overshoots and / or voltage dips and / or interference voltages within the power bus EB and / or the connected consumer (SPU with EC) and evaluates this data u.a. to a possible ground fault of a wire of the power bus EB and / or exceeding the threshold value for the influencing voltage.
  • the network node unit SND is always supplied in redundant manner from two sides with electrical energy and therefore has in the context of the switching module S via a left switch S1 and a right switch S2 and a load switch S3 to the supply unit SPU of the element controller EC.
  • the network node unit SND also supplies the communication unit SCU with voltage and can also use this data via an Ethernet connection It is therefore integrated in the data bus CB (eg activation of manual operation of the SND via remote access and actuation of switches S1 to S3, delivery of diagnostic data to the signal box or a higher-level service and diagnostic system, polling of the current voltages, currents, energy and energy Power values, parameterization of the SND, data for charging an energy storage device not shown here, or the registration of a future power requirement).
  • the supply unit SPU is integrated via the switch S3, which converts the voltage of the power bus EB to the input voltage required for the element controller EC.
  • a data connection between the switching module S of the network node unit SND and the supply unit SPU, for example in the form of a serial RS 422, is provided.
  • Energy-technically typical here is, for example, a three-phase connection with 400 VAC.
  • the element controller EC controls and supplies in FIG. 2
  • the switch W receives the element controller EC data telegrams from a higher-level interlocking CPU via an Ethernet connection from the communication unit SCU and are via this communication unit SCU feedback to the interlocking computer CPU.
  • the interlocking computer CPU can also represent a corresponding evaluation module that evaluates the received data as intended. In the present case, however, emphasis is placed in this embodiment on the control and evaluation logic SL integrated in the network node unit.
  • FIG. 3 shows a schematic view of an example of the separation of the power bus EB in the event of detection of a ground fault and / or an excessive value for the influencing voltage.
  • PS1 or PS2 are the feed points for the power bus EB.
  • PS1 is also as left Feed point PS1 and correspondingly the feed point PS2 referred to as the right feed point PS2.
  • seven network node units SND1 to SND7 are sequentially connected in the power bus EB.
  • the entire power consumers of the Element Controller Unit E are hereby referred to as consumers V1 to V7. Power consumers in this sense include the Element Controller EC and the upstream supply unit SPU.
  • Each network node unit SND1 to SND7 measures the influencing voltages and checks for the presence of a non-operational earth fault. If now the limit value for the influencing voltage is exceeded and / or the presence of a ground fault is detected, the energy bus EB is projectionally separated by the network node units SND4.
  • the network node unit SND 4 is configured such that it opens its right switch S2. The consumers V1 to V4 are then supplied only on one side of the left feed point PS1 and the consumers V5 to V7 accordingly only from the right feed point PS2.
  • the energy bus EB is fed by two independent energy networks EN1, EN2.
  • the infeed at the supply points PS1, PS2 is isolated.
  • the influencing voltage usually then becomes systemically important if, due to a fault in a wire of the power bus EB, there is a ground fault, which also represents a considerable source of danger for an electric shock for the maintenance personnel. Due to the separation of the energy bus EB approximately in the geographic center, this danger is also approximately halved.
  • the correspondingly configured network node unit SND4 sends a corresponding message to a diagnosis and maintenance unit, which can then take care of the elimination of the ground fault and / or the excessive influencing voltage.
