Definitions
- the invention relates to a method according to the preamble of claim 1. Such a method is known from DE 43 08 237 A1.
- DE 43 08 237 A1 discloses a method for operating an axle counting system reported, at which at the points of delivery formed Achsweakenede for free and Busy message adjacent Track sections to partially distant axle counters be transmitted.
- the axle counts will be off the sensor signals of trackside sensors formed on the passing over of vehicle wheels react.
- the metering points assigned pre-processing set here the sensor signals from pairwise cooperating wheel sensors in direction-dependent counting pulses.
- the transmission the axis counts to a remote counter is done via Telecommunication lines or wirelessly by means of corresponding message telegrams.
- the AchsJAimpulse the distant Point of delivery can only be transmitted if a train journey is about or in the associated track section pending or to take into account. Outside these times is the data transfer between the meter and the remote metering point interrupted and the monitored track section is occupied reported.
- Object of the present invention is the method according to to develop the preamble of claim 1 so that it leads to an even longer time limit for the transmission of information between the metering points and the counters comes. This would mean that with wireless data transmission the transmission costs lowered again and above in addition, also in the case of wired data transmission the overall smaller amount of data to be transmitted the security of data transmission could be raised.
- the invention solves this problem by the characterizing Features of claim 1. Thereafter, for the Freiund Busy reporting of a track section from each metering point in principle only two data telegrams to an associated Counter to submit, with the first to busy and the second to open the section is. In contrast to the prior art, no axle numbers transmitted online to the counter, but instead next to a license plate for the first axle of a train exclusively the number of axles of the car passing completely at the metering point Vehicle Association.
- the track part shown in Figures 1 to 4 consists from the track sections 1 to 3; he gets hit by a train Z traveled.
- the track sections are identified by metering points ZP1 to ZP4 limited, the track switching means in a known manner formed by two spatially offset wheel sensors become.
- the wheel sensors speak on passing vehicle wheels and thereby give temporally overlapping sensor signals pre-processing devices assigned to the points of delivery VV1 to VV4 off.
- These preprocessing facilities set the sensor signals supplied to them in driving direction-dependent Counting pulses for assigned evaluation devices A1 to A3.
- the preprocessing VV1 in Fig.1 counted four more axes than the preprocessing device VV3; the respectively determined number of axles is for clarification the process of advancing the move into the symbols have been registered for the preprocessing facilities.
- the transmission of the message telegram can, as in Figure 1 assumed, over existing data or supply lines between the points of delivery and the evaluation devices or but also take place via a separate bus system. Similarly Is it possible to transmit message telegrams wirelessly via a if necessary, between a point of delivery and a remote evaluation device to be established communication link transfer. In this case, the communication connection after the necessary for safety reasons Multiple transmission of a message telegram dismantled again.
- a telegram-oriented communication be provided without kauskin- and dismantling, for example over a constantly existing radio connection or through temporary Assignment of one of several open radio channels.
- a telegram-oriented communication be provided without kauskin- and dismantling, for example over a constantly existing radio connection or through temporary Assignment of one of several open radio channels.
- the preprocessing device VV2 determines Although due to the sensor signals supplied to them continuously Number of passing axles and direction of travel these axes; However, this information is not to the Track monitoring provided evaluation A1 and A3 transmitted.
- the preprocessing device VV2 determined in addition to the number of axes of trains passing the point of delivery ZP2 and their driving direction also, how big the time distance between the successive vehicle axles. By Comparison with a stored time value for the largest permissible distance between successive Vehicle axles of the vehicles of the slowest train applies, can the preprocessing device VV2 determine the time is to be expected that the train Z the point of delivery ZP2 completely happened. This case is shown in FIG.
- a slow moving train may be due to the time criterion be decomposed into several logical Achsverbünde. This can lead to more than two telegrams per turn, however the temporal density of these telegrams by the deposited Time value limited.
- Busy message B of the following track section 2 remains exist because the Vor Ltds droveen VV2 and VV3 the track section 2 limiting metering points ZP2 and ZP3 have stored different numbers of axles.
- For the later Free message of the track section 2 transmits the preprocessing device VV2 that of her after driving past of the train Z calculated counter value with a message telegram T2 * to the evaluation device A3.
- the preprocessing device VV2 that of her after driving past of the train Z calculated counter value with a message telegram T2 * to the evaluation device A3.
- the train is advanced and travels with his first axes the point of delivery ZP3.
- the associated preprocessing device VV3 recognizes this and gives one in this regard Message telegram T3 to the evaluation device A3 for Monitoring the forward track section 3.
- the evaluation device A3 then initiates the busy message of the forward track section 3, where it is irrelevant is whether it does this on the basis of the message telegram content, or due to the comparison of the pre-processing facilities VV3 and VV4 stored axle numbers.
- the busy message B of the past track section 2 remains.
- the train Z has completely passed through the point of delivery ZP3.
- the Preprocessing device VV3 the output of a message telegram T3 * to the evaluation device A3.
- This compares now the counting results of the past track section 2 limiting counting points ZP2 and ZP3. Assuming according to these determined by the associated preprocessing facilities Axle payers match.
- the evaluation device A3 then causes the free message F of the past Track section 2.
- the busy message B of the preceding Track section 3 remains in place until the train reaches the point of delivery ZP4 has completely passed and the evaluation device A3 Matching counting results of pre-processing facilities VV3 and VV4 has detected.
- FIG. 5 indicates an arrangement of counting points ZP5 to ZP8 a four-track route 11, 12, 13, 14. While the meter points ZP5 and ZP8 on them individually assigned pre-processing facilities VV5 and VV8 act, the metering points act ZP6 and ZP7 on a common preprocessing device VV6 /. 7 Theoretically also have the metering points ZP5 and ZP8 led to the pre-processing device VV6 / 7 could be; However, this is omitted, because then the supply lines from the wheel sensors of the meter points ZP5 and ZP8 below the tracks through to the common preprocessing device VV6 / 7 should have been conducted. In particular when retrofitting or upgrading an existing system to prevent such work on the track bed, there are the points of delivery ZP5 and ZP8 in the embodiment Figure 5 own pre-processing facilities.
- each receiving evaluation device it is advantageous to each to provide additional information to be transmitted, the make it possible for each receiving evaluation device, clearly recognizing that the data transmitted to them are determined and from whom they come.
- To be transmitted Data are then identifiers for the respective data source and for the respective data sink.
- the respectively transmitted Data is then preferably in the evaluation device store together with the respective addressee identifier.
- the data with a consecutive number and / or to provide a timestamp from which recognizable when it is from the preprocessing device of a metering point transmitted to an evaluation and / or of these were received. With such timestamps is to ensure that in an evaluation device not accidentally used on old, outdated axle numbers becomes.
- the inventive method can be anywhere with it Apply advantage, where distances by axle counting circles on their Free and busy status to be monitored. It offers especially where the transmission of axle numbers should be made by radio, because after the teaching of the invention only a very short-term data transmission is required. A short-term data transfer can also be implemented in terms of energy costs more cost than a constant data transfer, which is especially true for solar powered Transfer facilities is beneficial.
- the invention But is advantageous also applicable where the Point of delivery via supply or bus lines to the evaluation devices are connected. There you do not have to more like before in a very short time a variety of each current meter reading representing data to the Evaluation facilities are transmitted, but only still the data, the first and the last axis of a Zuges are assigned. This means that this data is lower Data rate (relatively narrow band) and time stretched can be transmitted, which is favorable to the transmission security effect.
