Definitions

  • the invention relates to a method of control and / or monitoring a traffic control and / or traffic-monitoring functional unit and on a Control and / or monitoring unit for control and / or monitoring a traffic control and / or traffic-monitoring functional unit.
  • the traffic flows are dynamically controlled and / or monitored.
  • functional units For example, display cross sections and conductor loops in the Roadway provided to control the flow of traffic or the Traffic density to capture.
  • functional units signals in incandescent or LED technology, Track occupancy and reporting equipment, Train completeness control devices, e.g. Axle counter, train control equipment, for example Loop cables, fixed balises and ETCS components, used, to the train traffic - even with often very high train occupancy - safe to control and monitor.
  • Actuators have the task of functional units (as they above enumerated by way of example) to steer differentiated and monitor.
  • Feedback to the System control devices usually signal boxes, take place periodic and contain the required regulatory Information on the railway process such as track occupied and the compressed results in short time intervals ongoing test intervals.
  • Siemens Switzerland AG under the Trade name MSTT® on the market such a control part offered ..
  • Such decentralized actuators usually have the Task, detached from interlockings, control systems or more generally speaking of data processing equipment, local on-site mostly in the track area arranged signal and to control safety equipment and / or their determine functional conditions and, if necessary, also their correct function, if necessary also in the idle state, too monitor.
  • the need for surveillance is in the process usually strictly standardized railway environment by the function assigned to the respective function Security level according to the current version railway technical standards, e.g. SIL4 according to EN 50129.
  • Such control and / or monitoring at the place of Function unit supports the detection of failures in these functional units and often do it first possible that also a gradual creeping Deterioration of process parameters of the functional unit, which are usually associated with a functional restriction, can be detected, usually in advance of a Failure occurs.
  • Decentralized control units are usually via a long supply line supplied with electrical energy from the interlocking.
  • a Supply unit in the decentralized control unit supplies the electrical supply for both the internal control and Control system as well as for the to be controlled Functional units.
  • the decentralized control part in usually a bidirectional data connection over which it Data for the control of her assigned Function units and to ensure its own Exchange functionality and safety of the control system.
  • This command and message information is using Telegram from the signal box, control system, one memory-programmable controller (PLC) or the like the decentralized control unit discontinued, with the decentralized Adjustment accordingly also messages in the opposite direction sends back.
  • PLC memory-programmable controller
  • control and / or Monitoring unit designated to indicate with which it possible, very different functional units in simple way to functionally to a decentralized control part couple, the even a correspondingly generous relevant schedulability / parameterizability.
  • the modulation of the payload to the feed signal there is one A variety of methods known in the art, including, but not limited to, the modulation of the payload to the feed signal provide.
  • a particularly easy and railway technology safe, operable with DC voltage solution can as Switching pattern for the electrical feed signal the use provide a pulse width modulated signal.
  • the pulse width modulated feed signal on a Function unit supplied power to be controlled. So is it is possible, for example, light signals (LED and Light bulb signals) in the light output by the temporal To regulate on / off ratio (duty rate), for example by lowering the electrical power to achieve the night lowering.
  • This regulation can both the intended function as well as function monitoring serve, e.g. the maintenance process in order to Luminous intensity regulation on a light signal means in frame a periodic monitoring cycle.
  • a possible variant, in particular at Function units with simple actuator structures applied can be used as a switching pattern for the electrical Supply signal the switching on and off of the supply signal provide.
  • a combination of both preceding switching patterns in a way possible that as switching pattern for the electrical feed signal the Switching on and off of a pulse width modulated Supply signal is used.
  • not all functional units are (yet) over the required properties for data transfer over the Supply or the data to be transferred too complex it can be provided for a transmission on the feed additional data to the functional unit and / or data from functional unit via a feed independent To transmit data transmission means.
  • Return status information to the actuator that is there read in and, if necessary, can already be evaluated.
  • a faulty status information for the functional test this data line can be triggered, for example, by briefly changing the feed signal or by a trigger signal at the data output of the actuator, which internal procedures in the functional unit starts.
  • a Relevant status information can be designed in this way be that a digital static signal the statement "Information good / bad” represents a periodic one or only in case of error existing data telegram with Status information is sent and an analog signal, e.g. in the form of a measured value, an A / D converter is supplied.
  • FIG. 1 shows a schematic representation of a decentralized control part ST, which controls a functional unit FE, in this case a railway signal S, and monitors.
  • the decentralized control part ST essentially comprises a controller ⁇ C ST and a power supply unit PSU.
  • a not further illustrated interlocking is arranged, which sends via a power supply electrical energy PS to the ST and a bidirectional data line control data CD to the decentralized control unit ST or receives from the decentralized control unit ST ,
  • the decentralized control part ST has a two-wire connection in a logical direction to the functional unit FE, via which the electrical power required for operating the functional unit FE is transmitted by means of a supply signal SS.
  • the railway signal S includes four signal lights L, which must be controlled in various single and multiple configurations, so that at least the controller ⁇ C FE is provided to control the signal lights L according to the originally coming from the signal box control data CD. Which of the signal lights but actually have to radiate with which luminosity is transmitted to the feed unit SS by the controller ⁇ C ST impressed signal pattern P + / P g to the functional unit FE.
  • An example of such a signal pattern P + / P g iST in FIG. 2 is provided in the form of a pulse width modulated signal.
  • the signal pattern P + / P g coded control variables while the Einschaltperiodendauer P + , the associated voltage V + , the Ausschaltperiodendauer P g , the associated voltage V off , resulting from the addition of P + and P g, the frequency f of the pulse width modulated signal.
  • the time variation of the frequency f can also serve as a control variable for the function of the functional unit FE.
