Definitions

  • the invention relates to a monitoring device according to the preamble of patent claim 1.
  • track-bound means of transport such as railways, subways and suburban trains
  • the route is generally set and secured from trackside control systems such as interlockings or higher-level control centers.
  • an employee In the signal box or in the control center, an employee (dispatcher) is responsible for the scheduled actions to be carried out and for monitoring their sequence, as well as for receiving warning and error messages from the control system.
  • the dispatcher uses an input device such as a control panel, control panel or screen input in the command direction, and a display device in the signaling direction that shows the respective status of the route as well as entered and running control actions in the form of a signaling picture.
  • Input device and display device can also be combined into one unit.
  • control commands in the control systems described are executed safely by the circuit logic alone, i.e. the control system automatically checks all admissibility requirements for an actuating action before it executes a corresponding control command.
  • the control system works according to safety principles, which rule out the occurrence of dangerous conditions due to failure of individual components or due to external interference.
  • failures or malfunctions like failures in the controlled guideway area, lead to operational inhibitions and, if they are not quickly identified and remedied, increase the likelihood of double faults, on the basis of which dangerous states can then also occur.
  • the dispatcher recognizes errors that occur from the report image or from the response or non-response of detectors provided in the display device.
  • errors that have occurred before they cause an operational inhibition can only be identified by analyzing previous actuating processes. In the vast majority of cases, such errors are not recognized by the dispatcher before the operational inhibition occurs.
  • the invention is therefore based on the object of providing a device which largely relieves the operator of a control system constructed as described at the outset of monitoring tasks.
  • the data processing system continuously records the status of all inputs of the display device relevant for the monitoring of selected picture image elements. It checks whether the selected switching state combinations are compatible with the logical rules stored in a list and issues a warning if this is not the case.
  • the data processing system does not interfere with the sequence of operations, and therefore does not require direct access to the control system circuit. It only evaluates the information that is also available to the dispatcher and that can be tapped at the display device. It works quickly, error-free and also detects errors that can only be identified by means of stored previous actuating processes. Since each signal box and each control center, regardless of the circuit technology used, always has a display device on which the required information is present, the monitoring device can be used in any such system without major adaptation measures.
  • claims 2 and 3 relate to the initiation of the monitoring process, after each change in the reporting screen - this makes sense in low-traffic times - or - in heavy traffic - at regular intervals.
  • the subject of claim 4 is the inclusion of sequence dependencies and time dependencies in the logical rules. For example, a rule is drawn up that says that if a certain condition of a route element is displayed, a certain other condition of the same or another route element must have been reported immediately beforehand, or a rule can be checked that states that no later than 6 Seconds after issuing a turnout command the lock indicator of the turnout in question must have reported it as locked in the commanded end position.
  • An embodiment of the monitoring device according to the invention described in claim 5 facilitates the inclusion of logical rules that have not yet been stored in the data processing system.
  • the monitoring device e.g. in the case of route changes, to be adapted to the new situation.
  • the subject of claims 6 to 8 is the takeover of routine checks by the monitoring device.
  • the daily turnout circulation test that is usual in a railway signal box is triggered by the monitoring device or a reminder is sent to the dispatcher.
  • the stress on guideway elements can be recorded statistically and, according to patent claim 8, depending on the number of stresses, functional tests can be triggered or reminded by the dispatcher or maintenance service.
  • a block diagram for a route control system is given, as it e.g. suitable for controlling train stations along a railway line.
  • route areas B1, B2 of two other unoccupied stations are controlled from the signal box of a central station.
  • Track diagrams of the three guideway areas are shown on a central table ST.
  • Control inputs can be made directly at the control table or via additional input devices, not shown, such as Number keypad, screen input, etc. can be made.
  • the lighting of the table is signal-safe.
  • the signal box logic ZSL of the central station is connected to the table, which directly controls the path elements FWZ located in the path area BZ of the central station and reports their status by activating display elements assigned to the path elements in the table ST.
  • connection circuit ZV Also connected to the control table ST is a central connection circuit ZV, which is connected to signal box circuits SL1, SL2 of the unoccupied train stations via a special data transmission link DUE which operates in a signal-safe manner and connected to this decentralized connection circuits DV1, DV2.
  • the connection circuits ZV, DV1, DV2 form together with the data transmission route, a remote control system that allows route elements FW1, FW2 of the unoccupied train stations to be actuated via the associated signal box circuits and to receive messages about the respective state of these route elements.
  • a monitoring device is now additionally connected to the control table ST, which comprises a data processing system UE, an extensive memory SP and display means.
  • the latter can be arranged on the table.
  • the function of the monitoring device can be described using the program structure shown in FIG. 2.
  • a program TQM adds additional time-controlled tests that e.g. Routine checks are assigned, which are to be carried out at specified time intervals, in the queue TQ.
  • the queue TQ is processed by a program FDC, which executes the test functions entered in the queue.
  • the test functions are assigned logical rules based on the control elements and element relationships contained, which are stored in the database and which must be fulfilled by the respective test function.
  • the FDC program checks compliance with these rules and delivers messages that are to be displayed on the ST table, via an intermediate memory ZSP2 with a mailbox function to a local output program FDP and thus to the table and the central connection circuit ZV for forwarding to the operating devices of the remote-controlled Train stations.
  • the messages generated by the FDC program are saved in a database DBK3 file.
  • each route element and its status must be clearly defined.
  • each element is assigned to an element type (e.g. switch).
  • Element types can have different display codes that indicate the current status of an element (e.g. "turnout right, free”, “turnout left, occupied”, “turnout turns right”, etc.).
  • Element types can also be related, e.g. a turnout includes a left branch, a right branch, a turnout tip, a turnout button, a locking detector and a blocking detector.
  • element W11 is a very specific switch in the guideway area of a train station. Become several If stations are monitored, the turnout W11 must be given a station identifier so that it can be distinguished from the turnout W11 of another station.
  • the switch W11 can be assigned to the lock indicator VM11.
  • Each rule stored in the database contains criteria in its definition, which state which interlocking messages should trigger the rule check.
  • the process REA determines which rule definitions agree with an interlocking message in element type, display code, station identifier and actuator element identifier and, if there is a match, places the check of the corresponding rules as a test function in the queue TQ.
  • the parameters "station” and "control element” can also be filled with placeholders.
  • rules can be generalized so that they apply, for example, to all control elements of one element type in all stations. For criteria with wildcard characters, the match is independent of the message within the corresponding field.
  • Such more general rules (which, for example, affect all turnouts in all train stations) can be overlaid by defining several rule definitions with the same name with less general rules (e.g. all turnouts in station B1 or turnout W11 in station B1).
  • test The result of checking a rule (test) is "true” or "false”, depending on whether the rule is fulfilled on the basis of the current report image information.
  • Each rule can consist of sub-rules (so-called test modules), each of which has the element type, display code, station, element parameters and must be processed in a predetermined order.
  • Each sub-rule returns "true” or "false”.
  • the overall rule is fulfilled if the sub-rules are fulfilled in accordance with their interrelation. If partial rules are linked with "or”, it is sufficient e.g. even if a sub-rule is fulfilled and the overall rule can be answered with "true”. If the sub-rules are linked with "and”, the checks of all sub-rules must deliver "true” in order to fulfill the overall rule.
  • the rule r and thus the The test is fulfilled if the sub-rules r1 and r2 are fulfilled or if at least one of the rules r3, r4 and r5 is fulfilled.
  • a track lock message is correct if either the track was already locked (one of the rules r3 to r5 fulfilled), or the track button and the so-called group button (two-button operation) was pressed for this track (i.e. if the sub-rules r1 and r2 were fulfilled at the same time).
  • Time dependencies and subsequent dependencies can be checked using the time parameter in the individual rules. Since every signal box message is stored at least temporarily, it can be checked whether e.g. an element had a specific display code at a specific time in the past.
