Definitions

  • the invention relates to a switch control in an electronic interlocking.
  • a point controller is used to control the drive of a switch in a rail network and to monitor the points position. Extremely high demands are placed on the failure and operational safety of the points control. For example, it must be ruled out that the points drive receives an actuating voltage as a result of a malfunction of the points control, while a train is currently traveling over the points. At present, only relays are used for signal-technically safe control of loads. The air gap between the open contacts is accepted as a captive separation point and is practically tested. Accordingly, known point controllers are constructed exclusively in relay technology. An example of this is disclosed in DE 1 222 963 B1.
  • a series connection of a relay contact and a semiconductor switch is proposed. This combines the advantages of both switch types. Through a combination of electronic switch and mechanical contact a wear-free switch with signaling properties is produced.
  • both switches are operated sequentially.
  • switching on the relay contact is first closed and then the consumer is turned on by the semiconductor switch.
  • switching off the consumer first switches off the semiconductor switch and then opens the relay contact.
  • the relay contact is de-energized and there is no burn-off (wear).
  • the point controller 1 has as a central control unit a double computer system 10 consisting of two microcontrollers of the type C167. This controller type and the associated operating system are already used and approved in other security applications.
  • a two-channel interface 11a, 11b is provided for connection to the electronic interlocking.
  • This can e.g. be designed as a parallel interface (for the ESTW Alcatel 6111 LockTrack), as a redundant CAN interface (for the ESTW Alcatel 6151 LockTrack) or as a bus interface for the connection of a TTP module (time triggered protocol) for the EWST Alcatel 6131 LockTrack. It can also be provided several interfaces that are equipped by application. Troubleshooting Diagnostics provide LEDs on the front panel of the assembly or are accessible through a maintenance terminal on a serial port.
  • the point controller 1 is connected via a classic four-wire interface with a point machine 2. This allows the point machine to be connected with minimal wire expense and compatibility with existing outdoor equipment.
  • the point machine includes a three-phase motor 211, 212, -213 that moves the switch to the desired end position.
  • Contacts 221-224 which are closed or opened by the switch blades, allow detection of the switch position by suitable test circuits 121, 122.
  • the test circuits are described in more detail in a co-pending patent application of the same inventor.
  • the power supply interface 110 includes, in addition to three three phase phases L1, L2, L3 (380/400 V), neutral N and ground point MP, a terminal for a 60V test voltage.
  • the dual-computer system monitors the point position and, when the switch is to be moved from one end position to the other, switches the three-phase phases L1-L3 via the four-wire interface to the point machine 2.
  • IGBT modules Isolated Gate Bipolar Transistor
  • Each module contains two IGBTs, one for the positive half-wave and one for the negative half-wave.
  • a relay WN is connected in series with the two semiconductor switches 131, 132.
  • a normally open contact of the relay WN and an electronic switch (equipped with IGBT) are connected in series. If pulse-shaped overvoltages occur in the case of a high-resistance electronic switch and an open relay contact, they are limited at the electronic switch by a respective varistor V1, V2. Therefore only overvoltages below the breakdown voltage of the semiconductors occur at the electronic switch. The overvoltage is applied to the air gap of the open relay contact WN.
  • a monostable, positively driven card relay is used, from which a contact pair is read back by the microcontroller. This realizes a testable network separation.
  • the position of the contact set of WN can be checked constantly via the readback contacts by the secure dual-computer system 10.
  • the relay contacts are operated as disconnectors, that is, they set the current paths, but switch no performance. This take over the semiconductor switches 131, 132 wear.
  • the load 211, 212, 213 turned on by the semiconductor switch.
  • the electronic switch can be checked in addition to each switching operation. In the state Relay WN switched on and IGBT still switched off, no current may be measured at the current transformers I Load and I off.
  • the point motor can advantageously be switched on at the zero crossing of the voltage and switched off at the zero crossing of the current. This is done by ELDP 111 (electronically programmable electronic device). After being enabled by the dual computer system 10, the ELDP 111 controls the in-phase control of the switching voltage.
  • Two additional relays R and L which are also designed as positively driven card relays, are used to control the setpoint position.
  • This information consists of the setpoint set point by reading back the storage relays and by checking the current flow in the monitoring circuit (60V).
  • the current flows through a series circuit of the switch of the monitoring voltage, the detector "monitored” with Auffahrprüfer 121 and the detector “Aveman” 122. All these modules are realized in semiconductor technology. This allows a monitored by the double computer pulse operation. By means of a suitable pulse control algorithm, failures in the monitoring circuit, wire connections and voltage incidents can be revealed by cyclic testing. The daily changeover of operationally not used switches can therefore be omitted.
  • Isolation transformers are used for galvanic isolation of the current paths.
  • Opto-couplers are used for galvanic isolation of the signal paths.
