Definitions

  • Relay house or relay box cabinet with EtherCat system Relay house or relay box cabinet with EtherCat system.
  • This invention relates to the wired transfer of data under real-time conditions, from a large number of digital and/or analog measuring data providing sources, such as digital and/or analog sensors, to a central unit for processing and/or storage of such data, such as a DPU (data processing unit), or a DAQD (data acquisition device), wherein the sources and the central unit are located close to each other and form a system, preferably within a relay housing or a relay box cabinet (hereinafter also referred to as "housing”),which system is operatively associated with a railway, for example, is arranged adjacent to a railway.
  • a relay housing a relay box cabinet
  • railway applications are also conceivable, for train, tram or metro, for passenger and freight transport, preferably with an overhead line over the railway line for the electric power supply of the train locomotive.
  • the system preferably fits within a ground surface being a maximum of 100 or 50 or 25 meters long and up to 100 or 50 or 25 or 15 meters in width, and/or can be located indoor or outdoor.
  • digital also means a digital analog-like signal having the function to present only two states, e.g. "on” and “off” or “in” and “out”, which states are usually substantially different from each other and/or provide substantially different sensor signals, for example, “0 V", and "24 V".
  • a sensor signal is as an analog signal applied to a digital input of the data-processing unit, and is at or after the digital input signal digitized by an A/D converter in order to be further processed as "real" digital signal by the digital working computer processor.
  • analog means an analog signal that has the function of presenting many states, which usually differ little from one another and/or lead to slightly differing sensor signals, for example a stepless between a minimum and maximum fluctuating value such as a temperature or a current or voltage level.
  • a sensor signal is presented as an analog signal to an analog input of a data processing unit and at or after that analog input, the signal is made digital by an A/D converter to be processed as digital signal by the digitally operating computer processor.
  • wireless data transfer is preferably meant that communication between the components of the system is via wiring, so preferably there is no wireless and/or radio communication.
  • the system for example, placed in a house, usually contains a large number of more than ten or a hundred galvanic relays for example, a railway security system.
  • a railway security system for example, of the type of security relay (so-called B relay, e.g. B1 relay).
  • the house is for example part of a railroad application dedicated to the management and control of turnouts and crossings, or track occupancy report.
  • the house includes, for example, at least ten of each of one or more of a level crossing relay, voltage monitoring relay, control relay, monitoring relay, track repeat relay (TPR) or track relay (the TR, or the so-called B2-Vane relay is a widely used track relay, the track relay indicates whether a train is located in the relevant track section).
  • TPR track repeat relay
  • the TR or the so-called B2-Vane relay is a widely used track relay, the track relay indicates whether a train is located in the relevant track section).
  • the house comprises galvanic features, such as supply cables, to feed the galvanic current (in language typical in the field "motor current") to electric motors for adjusting switch blades and/or switch frogs or to move barriers of railway crossings.
  • galvanic features such as supply cables, to feed the galvanic current (in language typical in the field "motor current") to electric motors for adjusting switch blades and/or switch frogs or to move barriers of railway crossings.
  • a B-Relay is a relay with a security function in a railway security system (including NX safety).
  • B relays have a very high degree of reliability, and operate for decades, provided they are regularly revised. Important features of B relays are that they for sure loose contact when the coil is not energized, and the normally closed break contacts ("back contact") open before make contacts ( "front contact”) are closed.
  • back contact normally closed break contacts
  • front contact open before make contacts
  • B-relay There exist several types of B-relay, with specific properties. The most common type is the 56001-783Gr1. This relay has two coils that operate on 12V DC, four switch contacts ( “full contacts”), two make contacts and one break contact.
  • B-relays which engage with a delay, disengage with a delay, are suitable for large currents etc.
  • B-relay is the track relay (TR).
  • This relay is a part of a track circuit, and is "on” when a track section is unoccupied, and falls off as the track section is occupied by a train.
  • B relays especially the B2 vane relay B2 (the “track relay")
  • a movable element with the B2 relay, the “vane”
  • a reset force such as gravity
  • a so-called B1 relay is usually equipped with a reset spring.
  • a safety relay is supplied by the manufacturer in a sealed container.
  • the rear wall of the casing is equipped with contact ports that correspond to contact plugs (so-called terminals) which project from a contact block in the relay box.
  • a B relay is mounted by pressing his back against the contact block so that the terminals are inserted into the contact ports so the B relay, via to the terminals connected wires, is electrically connected to the relevant circuit in which the B relay must be included. If the housing after delivery by the factory is modified or damaged or the seal becomes broken, the product is rejected.
  • the housing includes many digital and/or analog sensors, e.g., at least fifty or a hundred, with which inside the house, the operation of the relays (for example, the relay position) in the housing and of the electric motors (for example, the motor current) outside the house is monitored.
  • the housing contains temperature sensors, preferably of the NTC type. The signals of all these sensors are to be transferred to a central collection point (in other words: central unit) in the housing, over the measurement signal cables.
  • the relay position is detected by a digital sensor (as a rule, supplies a digital-like analog signal) and the motor current and the temperature are detected by an analog sensor.
  • Each sensor obtains a number of times per second a measurement (this is also known as "sampling rate”), and sends the measurement data to the central assembly point.
  • each measuring signal by its own, separate power - or measuring wire is transferred to the central assembly point, so that there are large amounts of separate current wires in the cable ducts having a length of usually more than 5 m and in some cases more than 10 or 20 meters, with a length of the order of 30 meters or more being no exception.
  • Power leads that are no longer used due to a repair or modification may, in some cases, because of regulations, not deleted from the cable channel. Due to repairs and modifications usually power wires or cables are added to the cable duct so that, especially when no longer used power wires can not be removed, it becomes increasingly full and eventually overflowing.
  • a power wire when a repair or modification occurs, a power wire must be replaced by a power cable so that a repair or modification is permanently visible. Since a power cable is stranded, as a rule, while a power wire is single core, and usually not all conductors of the power cable will be used (often is used only one or two of the typically at least four conductors of the power cable), increasing the overcrowd of the cable channel.
  • the power cables or wires extend between a frame and the central assembly point within the space in the housing in which the frames and the central assembly point are located, and/or are positioned in a cable duct.
  • An alternative to the use of cable ducts is to place the power cables under the floor of the space in which the frames are located, for example in a basement.
  • power cords or wires are led through the bottom of the frame into the basement and come up again at or below the system cabinet.
  • the components to be monitored, as well as the associated sensors inside the house are in frames, for example racks or relay cabinets.
  • the object of the invention is for the system, preferably inside a relay or relay box casing, one or more of: increase the safety and/or reliability of the monitoring of the to be monitored components, such as relays, and power supply cables for electric drive motors of rail switches; more efficient use of the in the data processing participating hardware such as data processing devices and data-carrying conductors; low energy consumption; robust system; after being put in operation of the system inside the house, easy to repair and/or modify while retaining performance and properties; low cost of construction; less sensitive to one or more of interference, crosstalk, mechanical vibrations, temperature fluctuations; take into account existing regulations; another, implicit or explicit, object disclosed herein.
  • the housing comprises intermediate stations (also called "module") of at least two types, and/or at least two or three or four or five intermediate stations.
  • the first and second intermediate stations are separate and preferably located at a mutual distance, preferably at least 1 meter.
  • An intermediate station preferably comprises one or more of: an A/D converter for digitizing the signals originating from the connected sensors; an Ethernet like output which is by a wire or cable data communicating connected to the central assembly point; an electrical processor for processing the data from the sensors; means for real time transmission of data to the central assembly point, for example, EtherCat like; means for receiving by wire of analog data from the sensors and transmitting by wire of the on the received analog data based digital data to the central assembly point; is associated with a single frame; is placed in or on a frame; is or is not the only intermediate station of the frame associated with it (for example, a minimum of two or three or four intermediate stations in the same frame).
  • the length of the one or more cables or wires for data communication with the central assembly point is at least 5 or 10 or 20 meters.
  • Another advantage is that the number of power cables or wires for data communications which runs to the central assembly point from the intermediate stations, can be significantly less, in many cases less than one-half or one-quarter.
  • the invention may optionally increase the flexibility in the design of the equipment to be installed in the house.
  • At least one or two separate measuring leads extend to the associated intermediate station from each sensor.
  • Cable ducts for example, run from the central assembly point, such as a system cabinet, towards the sensors.
  • the central assembly point such as a system cabinet
  • the frames e.g. rack, or a relay box
  • These measuring cables are connected to a module and from the module a smaller number, or a single communication cable, extends in the direction of the cable duct.
  • a module is a Sensor Interface Module (abbreviated: SIM) or Digital Input Module (abbreviated: DIM).
  • SIM Sensor Interface Module
  • DIM Digital Input Module
  • To a SIM are connected to measuring leads or wires originating from analog sensors, which supply analogue measuring signals to the SIM.
  • DIM To a DIM are connected measuring leads or wires originating from digital sensors, which deliver digital measuring signals to the DIM.
  • a space saving can be realized in the house, for example, less wall space is required.
  • system cabinets are less required, which, moreover, can be made smaller.
  • System cabinets usually occupy wall space, however, wall space in a house is limited.
  • the central assembly point for example, the system cabinet, there are preferably one or more, for example, a minimum of two or three, Data Processing Units (abbreviated: DPU), and optionally one or more Power Supply Units (abbreviated: PSU).
  • DPU receives signals via the communication cables from the S IM and the DIM.
  • PSU provides the galvanic power supply f or one or more of SIM, DIM and DPU. This feed is preferably supplied from the PSU via a star network.
  • each module or central collection point e.g. DPU
  • each module or central collection point has its own power supply, which is connected to a PSU.
  • a module or a DPU comprises one or more of an FPGA (Field Programmed Gate Array), CPU (Central Processing Unit) or microcontroller and computer memory, which are mutually connected operatively for data transfer.
  • the FPGA is a hardware-programmable computer component and provides fast data processing, thus relieving the CPU.
  • the central assembly point of the state of the art is a so-called data logger.
  • a type of data logger was selected.
  • Well-known examples of types of data logger are as follows (in parentheses the number of signal inputs): K-logger2020 (2 temperature, 20 analog, 20 digital); G-logger3060 (2 temperature, 30 analog, 60 digital); G-logger6060 (4 temperature, 60 analog, 60 digital); G-logger30120 (2 temperature, 30 analog, 120 digital).
  • a module of either analog or digital type i.e., configured to receive either analog or digital measurement signals, is optionally in combination with one or more inputs for temperature measurement signals.
  • Temperature measurement signals are typically analog signals, however, relatively weak in the case of, for example, an NTC temperature sensor, so that a separate input for the temperature sensor is more suitable.
  • Using analog and digital modules enables further hardware savings within the house, for example, by reducing the number of unused signal inputs.
  • the housing of one module type for example digital type, contains at least two, three or four times as many modules as the other module type, for example, analog type.

  • the system processes 132,000 samples per second.
  • each connected sensor has its own channel.
  • the inventor was surprised to have managed to develop a system that, by means of wired communication, allows for real-time transmission of data from the sensors via the intermediate stations to the central assembly point, preferably wherein each sensor performs continuous measurements, per second at least 1000 or 1500 or 1750 or 2000 measurement samples (also called “sampling rate") and this number of samples arrives in real time at the central assembly point, where it is processed, in which all this data is transmitted through wiring.
  • sampling rate also called “sampling rate”
  • the system comprises means for, under real-time conditions:
  • the scanning engine e.g. EtherCAT
  • the raw EtherCAT interface for more influence on the performance
  • use of as little as possible overhead for the data preferably 16bits raw per channel, rather than double (64 bit) per channel
  • of the dual core CPU is a single core assigned to the EtherCAT processing
  • the EtherCAT processing has a high priority on the allocated core.
  • a module is preferably configured as a slave, and the DPU as a master.
