Definitions

  • the present invention relates to a method for the diagnosis of spatially distributed plant components, in particular components of the train protection and train control, which consume electric power to fulfill its intended purpose.
  • Such usually decentralized system components are used in particular in rail 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.
  • 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 non
  • the previously customary and approved monitoring strategy for the decentralized system components is lost because of the no longer existing point-to-point connection. So it is, for example, in existing switch diagnostic devices so that they Measure the voltages and currents when changing over a switch by attaching voltage and current transformers to the supply lines to the point motor motor.
  • the signal term to be displayed on the signal is transmitted from the signal box card to the trackside signal control unit by means of a modulated AC voltage signal, and the corresponding current flow of the lamp currents activated according to the transmitted signal term is monitored on the signal box card.
  • the present invention is therefore an object of the invention to provide a method for diagnosing spatially distributed equipment components, in particular components of the command and / or train control, which consume electric power to fulfill its intended purpose to specify that in terms of the required cabling and the use of Monitoring components designed much simpler.
  • Another example could be the power consumption of a switch motor, which shows a conspicuously high and long power consumption at the beginning of the Weichenumstellieri and therefore could be an indication that the sliding conditions for the switch blade on the sliding chairs are no longer optimal and therefore a lubrication of the switch required should be.
  • a specific plant component can be customized, it may be useful to record the commissioning of a plant component, the current and voltage signature and this of the respective plant technology Assign component.
  • a difference in the start-up of turnout motors can be customized, so that any deviating at most from the usual current and voltage curve for turnout engines course is not fundamentally already be assessed as a mistake, but just a certain deviating from the beginning plant technical component, here another point motor or identical point motor, but special switch configuration / situation, can be assigned.
  • system components connected to the supply line can be gradually or individually isolated or grouped together from the supply line. So it is possible on suspicion To isolate a faulty system component by isolating individual equipment component in an expert mode the cause of a different current and voltage profile.
  • railway track side arranged electronic units For the environment of rail-bound traffic, it is typical when used as equipment components railway track side arranged electronic units, with the railway track side arranged components components of the train protection and / or train control, such as signals, balises, track magnets, track circuits, axle, switches, line conductors , Railway barriers and the like, are controlled and / or supplied with power.
  • components components of the train protection and / or train control such as signals, balises, track magnets, track circuits, axle, switches, line conductors , railway barriers and the like, are controlled and / or supplied with power.
  • FIG. 1 schematically shows a modern interlocking architecture with a system SYS, inter alia, has a signal box STW, a redunant built data backbone NB1, NB2, a data bus CB and an energy bus EB with two feed points PS1 and PS2.
  • the interlocking STW controls the train traffic on a track section G, in which here, for example, signals S, points W, a level crossing Bue and axle counter AC are arranged.
  • These train protection and influencing components each connect 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 access to the data backbones NB1 and NB2 is given via each side of the annular data bus CB.
  • the data bus CB coupled with corresponding routers / switches SW to the respective data backbone NB1, NB2.
  • 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, a communication unit SCU and the actual element controller EC.
  • the communication unit SCU is for data exchange used over both branches of the data bus CB.
  • Energy side, the network node unit SND is designed so that it couples to both branches of the power bus EB.
  • the network node unit SND controls and monitors the power bus EB, detects current violations within the power bus EB and the connected consumer (SPU with EC).
  • the switching module S In redundant manner, it is always supplied from two sides with electrical energy and therefore has in a 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 switching module S also includes a control and / or evaluation logic SL that is used, for example, for measuring the voltages and / or currents at the inputs of the power bus EB in the network node unit SND.
  • the network node unit SND also supplies the communication unit SCU with voltage and can also exchange data with it via an Ethernet connection and is thus integrated in the data bus CB (eg for activating the manual operation of the SND via remote access and actuation of the switches S1 to S3, for delivery of diagnostic data to the interlocking or to a higher-level service and Diagnoseosesyt, query the current voltages, currents, energy and power values, parameterization of the SND, for delivery and / or receipt of data for charging / energy management of an energy storage not shown here or for 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 eg in the form of a serial RS 422, 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 here also represents a corresponding evaluation module that evaluates the received data as intended.
  • the present invention proposes a method which is comparatively simpler than the system SYS. This method is also expedient if the monitoring and control solutions currently used as standard interlocking technology with conventional relay interlockings and / or electronic interlockings is used.
  • the procedure now provides that - as in FIG. 3 shown - several electrical loads ( plant components) V1 to Vn are connected to a supply line L.
  • the supply line L itself is connected to a power supply unit PS and obtains from there the electrical power required for the consumers V1 to Vn.
  • an ammeter 2 and a voltmeter 4 are connected, which measure the current and voltage waveform and transmitted to a diagnostic device 6.
  • the ammeter 2 and the voltmeter 4 are switched into the supply line L in such a way that the current I flowing between a power supply unit PS and the consumers closest to the power supply unit PS and the voltage U are measured.
  • the diagnostic unit 6 evaluates the current and voltage values supplied by the ammeter 2 and voltmeter 4 by comparing these actual consumption values with the current and voltage signature recorded for the consumers V1 to Vn in the undisturbed state during the intended function. If a predetermined deviation is achieved, a diagnostic signal is sent to a service point 8 and / or a maintenance person. In this way, entire supply areas can be monitored with a large number of consumers V1 to Vn arranged therein with little effort with this method. Therefore, this method requires neither arranged at the individual consumers diagnostic means nor a point-to-point wiring from the interlocking to the consumers V1 to Vn.
  • the diagnostic unit 6 can basically all types of electrical loads are monitored with the diagnostic unit 6, if for each of them a characteristic pattern of the consumption values of voltage and current (current and voltage signature) can be determined.
  • the diagnostic procedure is therefore in Essentially, on the basis of the known patterns of the current and voltage profiles, to identify those consumers whose actual measured values for the current and the voltage differ in their characteristics from the characteristic recorded for normal operation.
  • the diagnostic unit 6 Due to the central arrangement of the diagnostic unit 6 in such a power supply infrastructure, it may also be necessary to provide further possibilities for the localization of detected faulty consumers. This localization can also take place, for example, by the gradual targeted actuation or isolation of individual consumers or consumer groups (for this purpose, see the indicated switches in FIG FIG. 3 ). By observing the current and voltage profiles which change as a result of this actuation or insulation, and thus the diagnostic results derived therefrom, it is possible to conclude that a consumer affected by a malfunction can be detected. Furthermore, the signatures for the current and voltage curve can also be recorded during commissioning by the diagnostic unit 6, which can thus be assigned to the individual consumers V1 to Vn. In the course of operation, the diagnostic unit 6 can track the changes in the current current and voltage curves and clearly identify the affected consumer as defective if the limit values are exceeded.
