Definitions

  • the invention relates to the field of a passenger and freight railway, such as a train, tram or metro line, preferably with an overhead line above the railway for the electric supply of the train locomotive, whose train protection system is of the type "relay interlocking" or “electric interlocking", thus is based on, makes use of and is equipped with protection relays (so-called B-relay) in the electrical circuit.
  • the invention may be embodied in a system and / or a method for workplace security (also known as: warning system or warning method, respectively).
  • EP1308366 (Alcatel) discloses a solution electronic interlocking (ESTW), thus designed for solid state technology. Less relevant state of the art show EP2990296 (Dual Inventive) and EP3257718 (VolkerRail).
  • the word "sensor”, in addition to or in addition to or in replacement of the usual definition, is intended to mean an electrical or electronic device that collects information and / or data directly and / or indirectly and may also be “detector” or “relay interface”.
  • a sensor is for example a thermometer (an example of direct data collection) or a DI (digital input), which is an example of indirect data collection.
  • This description is particularly intended for a sensor (also referred to as "monitoring sensor” in this document) that is associated with a relay in the manner according to the invention.
  • the sensor is in communication with a processing unit, such as a server computer.
  • Sil refers to " Safety Integrity Level", which is part of the IEC61508, IEC61511 and IEC62061 standards. There are four levels and Sil-3 is the second highest level. The higher the level, the smaller the risk of dangerous failure of the system or method.
  • decommissioning This prevents train movement can be set to work, with the goal to create a safe workplace.
  • decommissioning is waived and "guaranteed workplace safety" used in which the train obtains unobstructed passage and the approach of a train is monitored by a warning system and people may only enter the track when an approaching train is still sufficiently far removed from the workplace. Has the train approached a critical distance, the system provides a guaranteed alert to the track workers which are then supposed to immediately leave the track.
  • the invention exclusively relates to "guaranteed workplace safety" by "guaranteed warning”, using a warning system of sufficient reliability.
  • section For example repairing a damaged rail

  • placing a short-circuit lance is cumbersome and time-consuming and dangerous.
  • the self-signalling short-circuit lance (ZKL) is the most commonly used means in the Netherlands (workplace protection device) to take the track out of service.
  • the decommissioning system is based on the and / or effective use of short-circuiting the track circuit. As a result, a train is simulated, a busy section is reported and it is no longer possible to send another train to this location. That way the work team can work safely. In most of the Netherlands track circuits used for train detection. This is an important condition for applying the ZK L.
  • the operation of the track circuit is explained below.
  • the ZKLs are placed in the track at the start of the work at the boundaries of the working area and removed from the track at the end.
  • the time required for security activation (i.e. the establishing and displaying the workplace) takes sometimes half an hour using ZKL ' s. During this time it is not possible to work on the railway, but no train traffic is possible. It is desirable to keep this time as short as possible, for example by taking and removing the safety measures more quickly in case of decommissioning.
  • the following actions currently take time walk from one location to the other where the ZKLs must be placed; placing the ZKLs; communication between LWB (Leader Workplace Security) and LLV (Leader Local Security); checking signals or switch positions in specific situations; create a safe work location for the official who must take the safety measures by preventing him from having to enter tracks that are not yet out of service at that time.

  • Train protection systems provide information to train drivers as to whether and, if so, at what speed a certain part can be safely driven by the train. For proper operation, these train protection systems require information from the track about the presence or absence of trains in a certain section of track. Train detection systems fulfil this function and pass on the status of a track to a train protection system. This operating principle is also used within the field of decommissioning to create a safe workplace for track workers. By thinking that a piece of track is 'occupied', the train protection system cannot allow other trains to access that piece of track.
  • a track circuit is a circuit formed by an electrically insulated track section (section) . Hi there is an alternating voltage connected on one side and a relay on the other. In the idle state (that is, there is no train in the section), the circuit is closed and the corresponding B relay is switched on. If the two rails are now electrically connected to each other (shorted), the circuit changes and the current no longer flows through the relay. Even if the circuit is broken (break in the wiring or in one of the rails), the current from the power supply can no longer reach the relay. The B relay drops out and this is signalled and leads to the track occupancy message.
  • NL2013825 and NL1040280 relate to decommissioning.
  • NL2013825 discloses an alternative to the ZKL, for which a provision is made inside a relay house.
  • NL1040280 discloses arranging lights along the entire rail network and causing the lights to light up alongside service track so that track workers immediately see which track is safe.
  • the temporary sensors communicate with a mobile alarm system that is temporarily installed in the vicinity of the track workers and gives an alarm to the track workers as soon as the warning system concludes on the basis of the signal coming from the temporary sensors that a train is at a critical distance is approached to where the track workers are busy in the ear.

  • a B relay is a relay with a safety function in a railway protection installation (including NX protection).
  • B relays have a very high degree of reliability, and will last for decades and years, provided they are regularly overhauled. Important properties of B-relays are that they are guaranteed to fall off when the coil voltage is without power, and that the normally closed contacts (in jargon "back contact") open before the make contacts ("front contact”) are closed.
  • B relays There are various types of B relays, with specific characteristics. The most commonly used type is the 56001-783Gr1. This relay has two coils that operate on 12V DC, four changeover contacts ("full contacts”), second make contacts and a break contact. Furthermore, there are B-relays that come on with a delay, fall-off, are suitable for large currents, etc.
  • B relay Another type of B relay is the track relay (TR). This relay is part of a track current loop, and is "on " when a track section is unoccupied, and drops out if the track section is occupied by a train.

  • An example of individualized B-relay delivery of the information is the equipping or associating of each B-relay involved with its own, individual monitoring sensor.
  • a free contact of the relay It is preferable to connect the sensor to a free contact of the relay, with a view to the undisturbed operation of the train protection system and sufficient reliability of the signalling by the sensor (e.g. minimum Sil-3 level).
