Definitions
- the invention relates to a switch control with monitoring of Point position in an electronic interlocking.
- a point control is used to control the drive of a switch in a rail network and to monitor the setting of points.
- signal relays are used in point controllers to the Monitor point position.
- the point machine is connected via four cable wires with the control module in the Interlocking connected (four-wire interface).
- Each cable core is a Line resistance from 0 to 56 ohms allowed.
- Monitoring the Point position takes place by means of a monitoring current through all four Cable cores flows.
- There are two monitoring relays “monitor” and “Avemfahrmelder” used by tightly tolerated suit and waste stream Marked are.
- Another disadvantage is that the Line resistance can be compensated via an adjustable resistor got to.
- relay controllers executed in relay technology have a high level Space requirements. Therefore, the development of electronic point control desirable for an electronic interlocking.
- the electronic circuits used are cheaper than the known signal relay.
- the point controller 1 has as a central control unit Dual 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 safety applications.
- a two-channel interface 11 a, 11 b is for connection to the electronic interlocking provided.
- This can e.g. 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 connection a time-triggered protocol (TTP) module for the EWST Alcatel 6131 LockTrack be trained. It can also provide multiple interfaces be, which are equipped according to the application. Diagnostic functions for Troubleshooting provide LEDs on the front panel of the module or are over a maintenance terminal accessible at a serial interface.
- the point control 1 is via a classic four-wire interface with a turnout drive 2 of known type connected. This allows one Connection of the point machine with minimal wire expense and Compatibility with existing outdoor facilities.
- the point machine contains a three-phase motor 211, 212, -213, the switch in the desired End position moves. Contacts 221-224, through the switch blades closed or opened, allow recognition of the Crossroads.
- the power supply interface 110 includes three three-phase currents L1, L2, L3 (380/400 V), neutral N and ground point MP a connection for a 60V test voltage.
- the dual-computer system monitors the Switch point and switches when the switch from an end position in the another is to be made, the three-phase L1-L3 over the Four-wire interface for point machine 2. Switching the Supply voltage via semiconductor switches 131 and 132. For this purpose are used so-called IGBT modules (Isolated Gate Bipolar Transistor), a combination of field effect and bipolar transistor. In a parallel this filed patent application of the same inventor will be closer described.
- Isolation transformers are used for galvanic isolation of the current paths.
- to Galvanic isolation of the signal paths are used optocouplers.
- two current limiters 121, 122 with provided different current values in the monitoring circuit. These are used as turnout monitors (WÜ) 121 and turnout detectors (WA) 122.
- the turnout monitor 121 has a current threshold of 50 mA
- turnout detector 122 has a current threshold of 150 mA.
- the monitoring of the point location is carried out with a monitoring current, which flows through all four cable cores of the four-wire interface 3.
- the monitoring current is about 50 mA established. From approx. 30 mA the detector 121 signals the double computer system a current flow.
- Detector 122 has a current limit of approx. 150 mA. From approx. 100 mA, detector 122 reports a current flow. The switching threshold for this Message must be in the range greater than 50 mA and less than 150 mA, is thus relatively uncritical.
- Detector 121 limits the current to 50 mA and reports a current flow. Detector 122 however, does not report any current flow.
- the detector 121 In the ascended state, the detector 121 is activated by a contact in the Switch point drive bridged. The current rises to 150 mA, detector 122 reports a current, detector 121 is not. The messages "monitored” and “ascended” are issued by the two detectors antivalent.
- FIG. 2 shows the monitoring circuit (in bold) in the monitored state.
- the Monitoring circuit is connected via a semiconductor switch 114 to the 60 V Test voltage connected.
- the turnout drive are those of the switch tongue actuated switch contacts 222 and 224 closed while the Switching contacts 221 and 223 are open.
- the point control is the Target position by the switching contacts L1, L2 and R1, R2 of the two relays L and R. established.
- the contacts L1 and L2 are open, while the contacts R1 and R2 are closed. This will cause a current to flow via the closed contact R1 and cable core 31 for point machine, from there via contact 222 and cable core 32 back to the detector 121 in the Soft control.
- the current limited to 50 mA flows over the closed contact R2 and cable core 33 back to Switch drive and from there via contact 224 and cable core 34 back to second detector 122 in the point controller, where the circuit then over the ground point MP for power supply in the signal box 3 is closed.
- the detectors 121 and 122 and the semiconductor switch 114 are through parallel varistors V3, V4, V5 protected against overvoltages.
- the current limiters can be used as constant current sources of known type be executed. To protect against overcurrent, the current limiter with Reserve line reserves.
