Definitions

  • the invention relates to a method for transmitting one of a metering point calculated meter reading to a central evaluation, the free or busy messages generated for a stretch of road.
  • the invention further relates to a Method for clearing a section of track and an electronic connection box for a metering point.
  • axle counters are used, in particular in connection with train free signaling devices.
  • Modern axle counters as they are z. B. from an article by G. Poppe with the title field of application of the new microcomputer counting point Zp30C, ETR, 41 (1992), H. 7-8, pages 519 - 522, known, consist of several arranged along the route points of delivery and a commonly located in a signal box central evaluation.
  • Each point of delivery comprises two rail contacts and a drive circuit called the electronic junction box (EWC).
  • EWC electronic junction box
  • the metering points transmit their counter readings to the central evaluation device at their request.
  • the evaluation device compares the incoming meter readings with each other, corrects them if necessary and generates free or busy messages.
  • the points of delivery to the evaluation device do not transmit counter readings but in real time the output signals generated by the rail contact (possibly amplified). Only the central evaluation device generates count pulses and counter readings.
  • a railway safety system in which decentralized safety devices, to which one or more infrastructure elements are connected, communicate event-orientedly via public mobile radio networks with locomotives.
  • This known system is particularly suitable for regional railways and enables operation in which the traction units request status messages via radio even when affected decentralized route safety devices (switches, track vacancy devices, etc.) affected by the intended journey.
  • the status messages received in the traction vehicle are compared with reference data stored there. Only if there is a match, a driver's license is displayed to the driver.
  • Central road safety devices (signal boxes) are not required in this known system.
  • the object of the invention is a method for transmitting the from a metering point meter reading to be reported to a central evaluation.
  • the Procedure should be particularly suitable for low-traffic secondary lines and neither in the acquisition still in operation high costs for the railway operator cause.
  • This object is achieved by the invention, which listed in claim 1 Features.
  • This communication network may be, for example, a public or a mobile network. Which network in the individual case is preferable, will depend on the local conditions. Insists in the Immediately near the point of delivery, a connection to a public Fixed network, so it will u. U. especially for the sake of Reliability and the cost of be the cheapest to connect the metering point to this fixed network. Often, however the metering points are far away from public landlines. In these cases will be preferable to communication over a public mobile network. Conceivable is also, laid along the rail lines communication lines of the infrastructure manager - often designed as glass fibers - to use for this communication.
  • the communication to the central evaluation device via mobile it may make sense, especially at remote metering points be to provide a local power supply, such as a battery or a solar panel. It will need no communication or power cables to be relocated.
  • the central evaluation device AWE communicates with points of delivery ZP1 ... ZP3, where communication links are established only when needed.
  • a public telephone network PSTN a public telephone network PSTN.
  • the metering points and the central Evaluation device AWE are thus here with conventional telephone connections equipped, which allow a connection on demand.
  • public Telephone network the operator of the railways, of course, a not public or a self-maintained telephone or data network use. In general, every communication network comes into question, which Ensures an on-demand, call-based call setup. In this way, the cabling effort over solutions with fixed Switched point-to-point connections significantly reduced.
  • the communication link between the metering points ZP1 ... ZP3 and the central evaluation device AWE a radio connection. It is essential here that for the communication no own, constantly available radio channel is reserved, but that, as in the above shown pipelined case, a channel is assigned only when needed. In An area with a large number of field elements can thus have one or a few Channels all communications are handled, which is because of the existing Bandwidth shortage brings significant cost benefits. Especially in the Range of weakly traveled routes are those through the connection establishment or the channel allocation conditional time delays acceptable.
  • the radio connection is preferably a mobile radio connection.
  • mobile devices integrated, dialing into a public mobile network allow.
  • the data is sent to a base station via the radio interface BTS and from there to a mobile switching center MSC, which transmits the data to a Network PSTN forwarded.
  • the central evaluation device AWE is directly connected to the PSTN network.
  • the communication connection in this case includes both transmission paths of a wired as also a radio-based communication network. By including a (Mobile) radio communication is - apart from the connection of the electronic connection boxes with the rail contacts - no wiring required.
  • a metering point only then in the Dials in the communication network, if after the last registered axis passage a fixed period of time has elapsed. This means a departure from the process, how to hardwire it from known, with a central evaluation device Knows counting points. There, the transmission of meter readings on request through the evaluation device.
  • communication takes place only after completion of a train journey. This will be ensures that the central evaluation device on one side immediately over each Befahrungsereignis informed, on the other hand, but a communication link only for the period of time which is absolutely necessary for the transmission of the counting result is.
  • Fig. 3 shows an embodiment of an inventive electronic junction box EAK in a schematic representation.
  • the electronic connection box EAK Via an interface IFSK, the electronic connection box EAK is connected to rail contacts SK1 and SK2.
  • the signals picked up by the receiver coils of the rail contacts are supplied to an evaluation circuit AS via this interface IFSK.
  • the evaluation circuit AS has the task of controlling the two rail contacts SK1 and SK2, to generate counting pulses from the signals supplied via the rail contact interface IFSK and to determine therefrom a meter reading.
  • a second interface IFGSM provides the connection to the communication network
  • the communication network is a public mobile radio network according to the GSM standard.
  • the interface is therefore known per se GSM transceiver executed.
  • the communication network is a landline,
  • the interface IFGSM may be a simple X.25 interface. as they are often used in public data networks for packet-switched data communication used.
  • the evaluation circuit AS is connected to a timer circuit TIM.
  • These Timer circuit TIM is designed so that when one of the evaluation circuit AS supplied count a timer is started. The timer is running, until the next count arrives and resets the timer. exceeds the timer has a predetermined value, e.g. Eg 15 seconds, it is assumed that the end of the rail vehicle or the drawstring the rail contacts happened. The timer then issues a send command to cause that the determined meter reading is transmitted to the central evaluation device becomes.
  • the period of time after which lapse a send command is issued not once fixed, but from the timer circuit after evaluation of the time sequence of the previously received Counts set. Behind it is the idea that it's about speed of the passing rail vehicle depends on when you failing counting pulses can assume with very high probability that no more axes pass through the rail contacts. For example, follow a fast moving train the counts in short time intervals each other. The timer circuit evaluates these time intervals and provides, for example determines that the longest occurring distance does not exceed 1 second. From this size, the time interval is calculated, after its lapse a Send command is issued. For example, the calculation can be done in a simple Multiplication by a fixed value, about 5, exist. This means that five seconds Sent after the last registered axis passage of the send command becomes. On the other hand, on a slow train, between two axle passes several seconds, the calculated value becomes correspondingly higher lie.
  • the electronic junction box EAK relates in an advantageous embodiment the required electrical energy from a local power supply.
  • this is designed as a rechargeable battery ACCU.
  • a solar panel SOL To load the rechargeable battery AKKU is provided a solar panel SOL.
  • the electronic junction box EAK has a memory SP with input means KL.
  • the input means KL can as Wire bridges or, as indicated in Fig. 3, be designed as a card reader. With a card reader can be in a particularly simple way in the electronic Terminal box EAK addresses entered. Such card readers are preferred Also in the central evaluation facilities available to there the addresses of Entering points of delivery arranged along the rail route. On the cards Codes can also be stored, with the help of which data transmission in addition can be secured to possibly existing backup measures.
  • the central evaluation additionally on its own in regular time intervals establishes a connection to the metering points and meter readings queries. If the counting points equipped with means for performing self-tests are, they are preferably in the context of regular meter reading queries triggered and their result transmitted to the evaluation. In this way, defects in points of delivery can be achieved within the required exposure disclosure time identify.
