Definitions

  • the present invention refers to a system for the diagnosis and operation of apparatuses intended for generating and distributing power supplies, in particular for railway's safety and signalling plants.
  • the railway's safety and signalling devices are made up of all those apparatuses that form a signalling system for trains' fail-safe circulation, that is, such a system that in case of any failure of one or more elements making up a plant's single device or assembly of devices, the safety conditions will not fail: for example, a failure by which a device is not able to provide an all-clear way signal to a train, implies the circulation to be stopped.
  • the safety and signalling apparatuses include both station and network's plants.
  • the said apparatuses provide for the circulation, manoeuvring, dwells and composition of trains, etc.
  • the devices are installed, supported by suitable frames, within the relays room and allow carrying out manoeuvres and controls on the so-called "yard's utilities" which consist of signal fittings, grade crossings, switch points, rail circuits, etc.
  • the safety plants are installed within cabins and service sites (also called PDS in the present description).
  • the cabins or automatic block sites are those buildings wherein there are installed, supported by suitable frames, the devices which allow performing the manoeuvres and controls on the signal fittings present along the line on rail circuits for the automatic spacing of the trains (line's automatic block), etc.
  • service sites which are not used by the passengers but are necessary for carrying out particular manoeuvres on the trains.
  • service sites include: communication sites (also called PC) which, in case of a rail's failure, allow switching from a rail to another; junction or crossroad sites (also called PJ) which are located near the junction between two lines to allow the passage of trains from a line to another.
  • the station's plants IS may be more or less complex depending on the dimensions of the station's yard and, therefore, on the utilities being present; they are more complex than the PDS and PBA plants.
  • the power necessary for the IS devices is provided starting from the adjacent stations or PDS via transformation boxes (1KV station box for the supply of the automatic block) which feed a high-voltage (1000 V) distribution line.
  • each cabin Provided in each cabin is a transformation box (1kV box of the railway line) which, starting from the 100V-distribution line, generates the 150V ac voltage for powering the cabin.
  • a transformation box (1kV box of the railway line) which, starting from the 100V-distribution line, generates the 150V ac voltage for powering the cabin.
  • the cabin's utilities are then powered with voltages generated in the supply panel, starting from the 150V ac of the 1kV-box.
  • the supply systems for the FS- safety and signalling apparatuses provide, generally, state and alarm indications through relay contacts which are able switch upon defect or failure situations.
  • Such a signalling is essentially limited to the provision of general information about defects or failures, without specifying the nature thereof.
  • the staff in charge of the maintenance of the supply devices IS must therefore go to the site to carry out the manoeuvres and/or replacements as necessary to restore the plant's.
  • the IS personnel not always is provided with all the material required for repairing the failure.
  • the intervention time may be significantly long (requiring even a few hours).
  • a typical example may be provided by a failed cable (for example, due to an insulation defect) of the 100V-supply line for the PBA).
  • Such failure causes a tripping of the switch for the protection of the station's 1kV cabin that feeds the length of railway line in question.
  • the times necessary in this case to detect the failed cable may be significantly long and requiring the intervention of at least three persons, one being in the station ahead of the line, one in the other end of the line and one that has to go along the line, cabin after cabin, to carry out the necessary sectionings on the switches of the 1kV-boxes in order to isolate the failed length.
  • Another important aspect relates to the maintenance of the supply plants.
  • Some devices such as the generator sets, for example, require periodic service interventions for checking the proper start capacity of the motor, the state of the battery, the levels of fuel and oil, etc.
  • the existing cumulative alarm-signallings do not allow obtaining preventive alarm information. Accordingly, the problem is either detected upon the service intervention or it occurs when the generator set should intervene because of the lack of power: in this case the provision of energy is not ensured.
  • the object of the present invention is to overcome the above said drawbacks.
  • a series of modules is provided which allow, locally or from a central supervision site, carrying out in real time the diagnosis and operation of the supply devices which made up the supply plants in question; that it is possible to control, from a central supervision site, the information gathered by the peripheral sites located within the stations, the service premises and the line's cabins; that it is possible, by connecting to said modules, for example via a portable computer provided with a serial port, to require the stored data and the processed diagnostic information; that the system maintains its characteristics unaltered also after prolonged periods of non-use.
  • a system may comprise a central control unit UC, a plurality of peripheral units PU provided with means for connection to one or more supply devices AA, means for detecting the efficiency of the controlled-supply devices, and means for identifying the occurrence of possible defects. Provision is made for a transmission means, that is, a communication network RT disposed and acting between the central unit and the peripheral units.
  • the transmission network RT can be constructed in different modes: by routing the transmission via a modem on a dedicated line (usually available along a railway line); by transmitting data through optical fibres; by using radio-transmission or other suitable transmission means.
  • the central unit UC of the present system can be subdivided into two levels: first or front-end level FE, and second or back-end level BE.
  • the first level FE carries out the function of interface and communication with the peripheral units UP. Based on the characteristics of the transmission means RT, the first level comprises one or more units of data transmission which interface, on one side, with the communication guidelines, and on the other with a processor that controls the communication with the peripheral units UP. Preferably, the exchange of data takes place by using communication protocols allowing a suitable protection of the information exchanged with the peripheral units UP.
  • the second or back-end lever BE provides for the processing of the collected information and for interfacing the operator. It consists of a processor or, in more complex cases, of a network of processors which houses the system's software.
  • the software being used is based on a data-supervision, control and acquisition package (SCADA) adapted for the operation of the line protocol, that is, custom-tailored for the operation of the transmission protocol being used.
  • SCADA data-supervision, control and acquisition package
  • the operating software supervises over the operation of the whole system and allows setting and modifying its configuration after any subsequent expansions thereof. This occurs by simply updating the data-base of the system.
  • the said software allows programming the enquiry frequency, the type of messages to be delivered, and the transmission parameters.
  • the operator-interface software allows processing the gathered information and displaying the same on the monitor.
  • Each element of the monitored plant is representable by an icon to which various conditions can be associated relating to more or less complex logic boolean combinations which concern the actual states and values of the input quantities acquired by the system.
  • commands can be given by simply acting with the pointer onto identifying icons.
  • control in a permanent memory for example, a hard-disk
  • a file of the historical registred events a file of the historical registred events, and to print the parameters from the peripheral units as well as the state variations of the controlled members and the alarm signallings, if any.
  • the supply devices AA to be' controlled relevant the peripheral units UP may be more than one and located in different positions (for example in a relays room and central room in case of stations).
  • the peripheral units are provided with interfaces having special characteristics.
  • the special characteristics of the interfaces are the following: possibility of joining together the functions of passive interface and diagnosis device, that is, providing the passive interface with an "intelligence" or capacity of its own; possibility of communicating and exchanging data between different interfaces via a field bus RS formed, for example, by a serial RS485, optical fibre or other standard field bus, so that the wirings for the collection of data be reduce to a few connections (two to four supply and field bus wires).
  • FIG. 1 Shown in Fig. 1 is a block diagram with an exemplary embodiment of intelligent interface with bus RS485.
  • the intelligent interfaces make it possible to carry out the following functions:
  • FIG. 1 Also shown in Fig. 1 is a block F representing the supply of the peripheral unit UP via the two wires F1 and F2.
  • Such architecture will be a interface of master type more powerful (with higher processing capacity) than those of slave type and which collects, via the field bus, the information processed by different interfaces and implements more complex diagnostic algorithms.
  • AA1, AA2, ..., AAn indicate the supply devices
  • UP1, UP2, ..., UPn indicate the corresponding interfaces of the peripheral units
  • RS indicates a transmission network between the interfaces
  • CO indicates a data-concentrator
  • RT indicates the transmission means for connection to the central unit UC
  • FE and BE indicate the two levels of the central unit UC.
  • a first advantage consists in the possibility of providing the central unit UC, in real time, with data about the operating conditions of the supply devices installed in the peripheral units UP, along the controlled railway line under control, both in the stations, in the PDS and in the cabins as well.
  • Each of the peripheral units UP comprises one CPU which, on the basis of data collected by the device to which is connected (digital signals available from alarm contacts, and analog measures made through the insertion of suitable transducers), makes it possible: to store the changes in the operating state of the supply device by associating time information (date; hour, minute); to process diagnostic information about the monitored device and to signal any alarm situation; to provide any indication of maintenance based on the detected state.
  • the information can be saved in a nonvolatile memory of flash type. At any moment, the operator can require locally, via a serial interface, the unloading of the CPU's internal memory into a portable PC.
  • the intelligent modules also allow to carry out telecontrols on the supply devices by acting on motorized switches and disconnectors which are present, for example, on sectioning and protection boards and on railway line and station's 1kV-boxes.
  • motorized switches and disconnectors which are present, for example, on sectioning and protection boards and on railway line and station's 1kV-boxes.
  • the CPU therefore, provides for analysing the failure situation and isolating the out-of-order devices by possibly restoring power availability.
  • the automatic re-configuration can be enabled or disabled during the setup stage of the CPU through a command to be delivered on the programming serial interface.
  • the telecontrol system is centralized, such function can be enabled or disabled also from the central supervision site. The operator in the central site can then carry out manually the telecontrols on the switches of the sectioning board.
  • the telecontrol system allows temporarily overcoming the failure by powering the plant again.
  • the maintenance personnel on the basis of the indications provided by the telecontrol system, can arrange for the intervention by reaching the site with all the materials suitable for the repair to be carried out, thereby reducing the repair time.
  • the troubleshooting and re-powering procedure can be performed also automatically by the supervision software if enabled by the operators.
  • a further important advantage relates to the periodic maintenace operations that can be made from the central site.
  • a start test of the set no-load test or load test of the generator set.
  • the command can be given either directly by the central unit UC's operator or by programming the control system to perform the start or load tests automatically in order to check the proper operation of the generator set.
  • the CPU of the peripheral unit (or intelligent control module) UP associated with the generator set so as to carry out tests automatically with a preset frequency (for example, every week, every 15 days, etc.).
  • a preset frequency for example, every week, every 15 days, etc.
  • the peripheral units or interfaces differ from each other depending on the supply devices to which they must be applied.
  • they may include: a module for controlling a single switchboard, such as of UPS IS702 / ACEI IS344 from PL IS379 and battery; a module for controlling the supply panel of a station or PBA; a module for controlling board-modulated QM6 or QM12; a module for controlling and remote control-operating the sectioning and protection board; a module for controlling and remote control-operating the GE-Section CC/CA Board; a module for controlling and remote control-operating station and line's 1kV-boxes; or other types of modules according to the devices present on the supply plant.
