  • the system defined as Vital Computer Station Apparatus comprises a Central Logic Computer 2 with one or more vital operator interfaces, designated by numeral 3, connected thereto.
  • the Central Logic Computer 2 executes a logic program for monitoring the railway system and transmits controls to Zone Logic Computers (ZLC), designated by numeral 5, through a communication network 4.
  • Zone Logic Computers are designed to generate actuating or state-changing controls for wayside equipment, such as light signals, turnouts, etc.
  • numeral 6 generally designates the wayside equipment
  • numeral 5 designates the Zone Logic Computer which is designed to control the switch machines of the turnouts
  • numeral 5' designates other Zone Logic Computers.
  • the Zone Logic Computers transmit controls to actuating or driver modules, which generate the power signals for controlling or actuating the wayside equipment and receive feedback signals therefrom, and which include the module of this invention.
  • Figure 2 is a block diagram of the actuator architecture and Figure 3 shows the interfaces to the other system units.
  • the turnout control actuating module of this invention interfaces (arrow 101) with the Vital Computer Station Apparatus to receive the turnout throwing controls and further has interfaces with the mains, arrow 201, with the operator, arrow 301, and obviously with the turnout, arrow 401 and with a diagnostics system, arrow 501.
  • the interface 201 with the power supply system provides a three-phase supply current, 380 VAC, 50 Hz.
  • the interface 101 connects the actuator 1 to the Zone Logic Computer 5 and allows reception of controls and transmission of wayside unit feedbacks through the vital I/O; particularly three feedback signals, KN, KR and DISALM are transmitted to the Zone Logic Control 5, and the Zone Logic Computer transmits the two N and R control signals to the actuator 1 for throwing the turnout switch points to either operating positions, known in the art as Normal position "N” and Reverse position "R".

  • a communication network designated by numeral 8 in Fig. 1
  • FDB Field Diagnostic Bus
  • the interface 401 with the unit 6, i.e. the switch machine of the turnout uses special terminal boxes, which are mounted to the unit and contain devices that form the electric termination of the position monitoring circuit.
  • the actuator 1 is connected to the unit 6 through a cable having 3 conductors C1, C2, C3 (classical connection: control + feedback).
  • C1, C2, C3 classical connection: control + feedback
  • two separate cables are provided, each having 3 conductors C1, C2, C3 and C1', C2', C3', i.e. a first cable having three conductors C1, C2, C3 for control signals and a second cable, also having three conductors C1', C2' and C3' for feedback signals.
  • the latter connection arrangement allows to increase the maximum distance between the cabin and the unit. This is also required if the DC motor inside the switch machine has no mechanical limit contact (which means that the control current is not automatically switched off at the end of the control).
  • the user interface 301 includes:
  • the module of this invention is designed to accomplish the functions of: controlling the turnout; monitoring switch point positions.
  • the actuating module 1 of the present invention acts as an interlocking subsystem and is required to meet certain safety conditions, i.e. any unsafe state must be detected and the system must be later forced into a safe state in as little time as to ensure compliance with any application-specific requirements.
  • Safety states for the actuator of the invention include: no power supply to the unit; no unit position monitoring.
  • the module 1 is based on an inherent fail-safe architecture: the actuator 1 transfers power to the unit 6 in a vital manner, i.e. only when there is a control intention in the logic 5, which is expressed through the actuation of a Vital Output port 101 and with a sufficient delay to cover the response time of the Zone Logic Computer 5 in case of undue control.
  • the MGD subsystem uses operation principles that were already used in prior art actuators operating in AC electrified lines.
  • the actuating module 1 is an assembly composed of a disconnecting part and a module, which is in turn composed of hardware boards having well-defined functions, as reflected in principle by Fig. 2 .
  • the boards are function-specific, namely:
  • the motor of the switch machine is of the DC type and, for rotational drive in either direction to cause switch point displacement from normal position to reverse position and vice versa, the two conductors C1 and C2 that supply the power signal to one input for rotation in one direction and to another input for rotation in the opposite direction, respectively incorporate normally open contacts of the relay R1 which are closed in the energized state of the relay R1 and normally closed contacts of the relay R2 which are open when the relay R2 is in the energized state and have a reverse operation as compared with the normally open contacts of the relay R2 incorporated in the conductor C2, and connected in series with the normally closed contacts of the relay R1, which are open when the relay R1 is energized.
  • This configuration allows the power signal to be transmitted either on the conductor C1 or on the conductor C2 depending on whether the relay R1 is energized for throwing the switch points to the normal position or the relay R2 is energized for throwing the switch points to the reverse position.
  • the Actuating Board is composed of the following functional units:
  • All the above functional units cooperate to perform the turnout control actuation function.
  • the control disconnection function is accomplished by a galvanic power disconnection device 10; this disconnection device 10 ensures protection for the wayside assistant of the DM in case of power failure and/or in case of turnout maintenance.
  • the throw control (to the normal "N” or reverse “R” positions) is implemented by three printed circuit relays R1, R2, R3 whose normally open contacts NR1, RR2 or normally closed contacts N_ and R designated by R11 and R12 are introduced in the power circuit as shown in Figures 5 and 6 .
  • two normally closed contacts N_ and R_, designated by R11 and R12, of the relays R1 and R2 hold the power source 112 shorted C4, when there is no control signal KN or KR and, as better explained hereafter, allow circulation of the alternating current of the monitoring circuit overlying the control circuit.
  • the third relay R3 is an auxiliary protection relay which is energized in the control step by circuits other than those that control the relays R1 and R2.
  • the protection relay R3, which is normally disenergized, is used to disconnect the wayside cable (by operating on the common return conductor C3) from the AC-DC converter 112 on the power output and thereby afford considerably improved safety conditions in the idle state, particularly on AC electrified lines, in case of cable insulation failure to the ground.
  • the Actuating Board 12 is composed of an AC/DC power converter, whose output is vitally enabled by vital outputs of the zone logic computer 5; this "enabling" signal is indicated in Fig. 4 and Fig. 7 as ON_Vit.
  • Fig. 2 and Fig. 4 shows that, from the moment in which the Zone Logic Computer (ZLC) exerts its control intention by transmitting the control signal Kn or Kr, energization of the unit 6 may only occur after a minimum time ⁇ .
  • This "delay" is vitally ensured by a suitable delay circuit 612.
  • a stop signal which has a protective function, for example, in case of abnormal power absorption by the unit and any other hazardous event, thereby preserving the integrity of the electronics of the Actuating Board 112 and/or the motor in the switch machine 6.
  • Figure 7 shows the connections of the Monitoring and Diagnostics Board. As shown in Figure 7 , the board interfaces with:
  • the local Logic Computer 5 through the three signals: KN, KR and DISALIM, transmitted to three vital inputs respectively and through the N and R signals received from two vital outputs;
  • the board is composed of three functional sections:
  • This section implements the TC and RC functions, i.e. transmission and reception of feedback signals for determining the position of the switch points. It accomplishes the turnout state monitoring functions, and communicates information through two position feedback signals KN and KR, connected to two vital inputs of the Zone Logic Computer (ZLC) 5.
  • ZLC Zone Logic Computer
  • the feedback signal is transmitted and received at about 400 Hz from and to the unit through transformers T1 and T2, the former T1 for the Normal switch point position signal KN and the latter T2 for the Reverse switch point position signal KR.
  • the interface with the unit 6 may include 6 or 3 conductors, depending on whether or not a dedicated wire is used for feedback signals.
  • FIGS 5 and 6 show two simplified diagrams of connection options.
  • the transformers T1 and T2 for transmitting and receiving signals at 400 Hz are in the short-circuit branch C4 of the power output whereas, in the option with a separate cable for feedback signals C1', C2', C3', as shown in Figure 6 , the transformers T1 and T2 only have one point in common with the power circuit. Complete separation is not possible, due to the need for the Cable Insulation Check Section of the Monitoring Board, which is directly connected with the output of the Power Section, to check the efficiency of such insulation on both wires.
  • the presence of the auxiliary control relays R1 and R2 allows the position monitoring transformers T1 and T2 to be connected in parallel with the power circuit, thereby avoiding the need for oversize series-connected transformers designed to have the DC current requested by the motor flowing therethrough.
  • Figure 8 shows the block diagram of the switch point Position Monitoring Section.
  • the two carrier generators 20 and 21 are amplitude modulated to provide an additional safety key, particularly needed in 50 Hz drive system applications.
  • the feedback signal is transmitted and received through transformers, whose high isolation secondary windings are connected to the unit.
  • the RIT timer block 613 maintains the corresponding vital input of the local Logic Computer (ZLC) 5 "low” for as long as required for the latter to detect it; thus, it allows the local computer 5 to detect any so-called "short monitoring failures".
  • the module of the invention also has a Protection and Supervision Section.
  • This section has operational supervision functions. These functions are accomplished by a microcontroller, and the section receives information by interfacing with the other functional blocks of the actuating module 1.
  • the Protection Section energizes the control relay R1 or R2 according to the control intention (N and R signals) of the local Logic Computer (ZLC) 5; after the control step, the protection section also energizes the monitoring relays CTN or CTR, which further allow the feedback signal generated by one of the two transmitters T1 and T2 as described above to flow into a single receiver, which is always on.
  • the Supervision and Protection Section is also designed to disable power delivery by the Actuating Board 12 during the control step, through the control protection function, by generating stop and DISALIM signals or a DISALIM signal only, in response to predetermined events.
  • the events that trigger the control protection function are:
  • the stop signal has the purpose of inhibiting the DC/DC converter 112" of the Actuating Board 12.
  • the DISALIM signal is also generated to drive the third vital input of the local logic computer 5.
  • the control protection function may be also performed outside the control step, in case of wayside cable failure, in the loop (not monitored) of the next control operation; in this case, the DISALIM signal is only generated.
  • a periodic test is performed to check proper operation of the circuits designed to receive the control current.
  • the Diagnostics Section receives the following parameters from the two Position Monitoring and Protection and Supervision Sections:
  • the Diagnostics Section is mainly implemented in the microcontroller 24 that performs the Protection and Supervision functions, as shown in Figure 9 .
  • Such microcontroller 24 directly acquires all the magnitudes to be subjected to diagnostics, interfaces with the Cable Insulation Check circuit 25 (CIC) and with the Echelon "node" 22, which is used as a communication unit on the Field Diagnostic Bus 8 (FDB) network.
  • CIC Cable Insulation Check circuit
  • FDB Field Diagnostic Bus 8
  • microcontroller 24 performs tests on the cable insulation check circuit, either upon user's request (user interface panel) or in a periodic and automatic manner.
  • the Cable Insulation Check (CIC) section 25 essentially comprises a 0.5 kHz square wave generator, connected to the input of the wayside cable C1, C2, C3 through a resistor of a suitable resistance, and a circuit for vector measurement of the absorbed current, which can detect cable insulation failure to ground, i.e. any reduction of cable insulation resistance, which can be configured in a step-wise manner.
  • the switch machines 6 are controlled by the actuator 1 which provides power supply to the unit 6 and performs monitoring functions thereon.
  • the interface is composed of two identical sections, one of which transmits at a certain time the indication of the (normal or reverse) position of the turnout unit 6 to the local Logic Computer (ZLC) 5.
  • ZLC local Logic Computer
  • the output transformer T1 of the normal position monitoring transmitter is closed on the remote capacitor CN. This triggers 400 Hz oscillation and enables relative position feedback (KN).
  • the output transformer T2 of the reverse position monitoring transmitter is closed on a low impedance, in the classical case. Thus, its oscillator is off and the output KR is disabled.
  • the above transmitter operates idly, thereby causing an oscillation at a frequency from 700 Hz to 2.5 kHz, which cannot enable the output KR.
  • the Zone Logic Computer (ZLC) 5 Upon switching from normal to reverse, the Zone Logic Computer (ZLC) 5 enables its vital output (R); after a short time, the CTN relay will be disenergized and the normal KN feedback will be immediately lost, whereupon the control relay R1 is energized. Then, a control protection Stop signal is transmitted to enable operation of the DC/DC converter 112". After another short vital delay, the ON_Vit power supply is enabled, to energize first the protection relay R3 and then the section for controlling the power DC/DC converter 112". Now, the actuator provides a rated voltage of 150 VDC to the winding of the motor, which causes displacement in the "reverse" direction.
  • the system logic cuts off the control operation thereby disabling the corresponding vital output (R).
  • control and monitor switch machines that do not automatically cut off current upon termination of the control operation.
  • a 6-wire connection is used, and the system may be configured to enable the monitoring relay CTR after a configurable delay from the time of closure of the control relay R2, regardless of whether the control current is cut off or not.
  • the end of the control operation is determined as the monitoring frequency is reached and the corresponding feedback is obtained.
  • the actuating module of the invention can handle abnormal operation statuses and ensure the highest safety.
  • the former is the state in which the module operates for most of the time and is characterized by the lack of controls, with the monitored unit in the Normal or Reverse position; the latter operating state is the one in which the unit is controlled, and feedbacks are necessarily lost.
  • abnormal states characterized by malfunctioning in the module, the unit and connection therebetween.
  • This event may occur in response to a control operation.
  • An unacknowledged control triggers a DISALIM signal.
  • the turnout may be monitored or not.
  • This event may occur during a control operation. Once the control operation timeout is reached, the unit is disenergized, the control operation is interrupted and a DISALIM signal is generated. The turnout may be monitored or not.
  • This event may occur during a control operation. This protection does not disenergize the unit, whereby the module will try and terminate the control operation. When the latter is terminated, a DISALIM signal will be generated. The turnout may be monitored or not.
  • This event may occur when there is no control operation and the turnout is monitored, in a normal or reverse position.
  • the module triggers a DISALIM signal, to prevent voltage from being transmitted, during the next control operation, to a circuit that has no load.
  • this protection may be excluded during configuration.
  • This event occurs at the end of the last admitted control operation. Once this control operation is terminated, a DISALIM signal will be generated.
