  • the status information 19 which signals the trains and serves for warning is transmitted between the reporting stations through a channel 29 in a known manner.
  • the signaling stations 1, 21 provide warning information 11 via a transmitter 17 and an information channel 5 to receiver 39 in warning stations 3.67.
  • the information channel 5, like the channel 29, can be a line, an inductive loop or a radio channel, a similar transmission medium or a mixture thereof, and can be identical or not identical to the channel 29.
  • the warning information can also be identical to the status information.
  • the warning stations 3.67 are usually portable and are carried, for example, by the persons to be warned in their work area.
  • the warning information 41 is passed from the receiver 39 to an evaluator 31, which emits the warning 41 at its output 53 when the warning information 41 is intended for the warning station 3.67.
  • the warning output 53 is usually an acoustic warning signal.
  • the transmission of the warning information 11 of the reporting stations 1, 26, 65 and 65 Warning station 3.67 must issue warning 53 to the work area of People are assigned to the alert by a location-based target area to ensure correct warning in the right place.
  • the reporting stations 1.21.61-65 set up in a chain.
  • One of the unbranched track 69.81ghi, 81hk of the location of the reporting stations 1,21,61-65 assigned route address 43 is stored in a default route memory 13 in the reporting stations 1,21,61-65.
  • One of the local warning information 11 assigned sector identifier 45 is in a sector specification 15 in the reporting stations 1.21.61-65.
  • the sector identifier 45 is the route section 69a-e Track 69.81ghi, 81hk, on which the reporting station 1.21.61-65 is located.
  • the route section ends where the route sections of the neighboring reporting stations begin.
  • By the route address 43 and the sector identifier 45 is the Destination area of the warning set.
  • the reporting stations 1,21,61-65 transmit the Warning information 11, 41 and the route address 43 assigned to the warning information the route default memory 13 and the sector identifier 45 also assigned from the sector specification 15 via the transmitter 17 and the information channel 5 to the Receiver 39 in the warning stations 39.
  • the range of the Information transmission 5 set so that the range is approximately uniform overlapped with at least the neighboring reporting stations 1,21,61-65.
  • warning stations 3.67 is a line address corresponding to the route address 43 preset in a line default memory 33 via a connection 49. It does that Destination reference to the unbranched track 69.81ghi, 81hk, along which the Move warning stations 3.67 freely. A branching track becomes another Route address 43 assigned so that the destination areas at least near the Junction can be clearly identified by the warning stations 3 if they are along of the track sections move.
  • route addresses are, for example: example 1 2nd 3rd 4th Route address 1 81ghi 81ghk 81gh 81ghi Route address 2 81hk 81hi 81hi 81ghk Route address 3 81hk Partial joint address of the track 81gh
  • the track sections 81ghi and 81ghk are assigned different track addresses, these track addresses having a distinguishable address for the track section 81gh which is assigned to them together. This can be done in a known manner by group addresses or subaddresses.
  • the assigned destination area of the route section 69a-e is determined by the sector identifier 45 in connection with its reception intensity 47 by the warning stations 3.67.
  • only a blank value is specified as the sector identifier 45 in the sector specification 15 in the reporting stations 1, 21, 61-65.
  • the warning stations 3.67 route the received warning information 41, the route address 43, the sector identification 45 and the intensity value of the reception 47 from the receiver 39 to an evaluator 31, which, in association with this information, continuously stores it in a circulation memory 35 when the route address 43 with the line address supplied to it from the line preset memory 33 is identical, that is to say the warning station 3.67 is located on the correct, unbranched track section 69.81ghi, 81hk.
  • the information from the circulation memory 35 is read back by the evaluator 31 and that warning information 41 is released to the output 53 for warning, the associated sector identifier 45 of which the predominantly greatest intensity values of the reception 47, for example field strength values of the electrical field of the transmission, are received within a predetermined time 32. exhibit.
  • the predetermined time 32 is dimensioned such that a possible reception of the neighboring signaling stations 1, 21, 61-65 is also guaranteed, so that their intensity values can also be recorded correctly.
  • An evaluation over a larger predetermined time 32 prevents an impermissible one Jumping "of the warning information between two route sections 69a-e in their border area.
  • the warning stations 3.67 can thus move freely along track sections, the evaluated warning information 11, 41 always the route section 69a-e unbranched track 69.81ghi, 81hk corresponds to the warning station 3.67 is currently located.
  • the detection of changing route sections 69a-e is clearer if the sector labels 45 in the sector specifications 15 of the at least neighboring ones Differentiate between reporting stations 1,21,61-65.
  • any distinctive features can be used, for example the Carrier frequencies of the transmitted information or sector addresses.
  • the Differentiation can only be two-valued and also with track branches repeat, so that in the simplest case with, for example, 2 carrier frequencies, or 2 sector addresses as sector default 15 or sector identifier 45 is sufficient.
  • 2a, 2b and 2c show typical destination areas of a section of a track section 69, 81ghi, 81hk with their section sections 69a-e. Are assigned to each other: Group 1 Group 2 Group 3 Reporting station 61 63 65 Route section 69b 69c 69d Broadcast intensity 71 73 75
  • a warning station 67 is located in route section 69c in the vicinity of route section 69b.
  • the assignment of warning, route section 69a-e and location of the Warning station 67 is applicable. Even in the case of a faulty reporting station 63 in FIG uninterrupted operation possible.
  • the evaluated route section shifts thereby to the nearest neighboring section, from 69c to 69b.
  • a better assignment the warning to the original route section 69c would be in this case desirable. This is done by:
  • the warning station 3.67 determines that the intensity values of the Receiving two different sector labels 45 from the recirculating memory 35 are approximately the same, the warning station 3.67 is located on the border between two route sections 69b and 69c (FIG. 2b) or on route section 69c (FIG. 2c) a faulty reporting station 63 (Fig.2c).
  • the evaluator determines sector information 45 associated with warning information 11, 41 31 Intermediate values of the warning information 11, 41, which serve as a more targeted, new warning 53 be issued. For example, there will be the higher priority warning information from the two evaluated warning information 11.41 preferred to issue 53.
  • Another possibility of a more targeted warning 53 is that the Signaling stations 1,21,61-65 the warning information 11,41 further warning information 11,41 add 69a-f for neighboring sections, recognizable for example by the relative Place of information in the telegram. If the evaluator 31 determines that the intensity values of reception 47 are of two different Sector labels 45 from the circulating memory 35 are approximately the same, so he evaluates the warning information 11, 41 for neighboring route sections 69a-f. The evaluator 31 selects warning information 11, 41 based on the relative position in the telegram for sections 69a-f which lie between the sections which correspond to the Warning information 11.41 of the two received, neighboring reporting stations 1.21.61-65 assigned. This allows the warning information in the arrangement according to FIG. 2c Reconstruct 11, 41 of the disturbed track section 69c and in the arrangement according to FIG. 2b achieve an additional route subdivision 69f.
  • the Track reference of the warning in a track reference memory 37 in the warning station 3.67 via a Connection 51 preset.
  • the evaluator 31 compares the track reference from the Track reference memory 37 with the track-related warning information 11, 41 and indicates its output 53 only those warnings whose track reference with the default matches.
  • the individual function blocks 11-15, 31-37 are expediently used in computer 2.4 their periphery 11-15,31-37 summarized, a computer 2,4 for security can be designed redundantly and the redundant computers monitor each other.
