Problems solved by technology

This degradation manifests itself as a malfunction that interferes with operation, which has a negative impact on the effectiveness of using the axle counting system, e.g. causing train delays
Diagnosis of the state of the ISDN connections involved in the transmission of information, i.e. of the state of the ISDN lines and of the ISDN modems, can only be carried out by means of tests which require an interruption of the operation of the axle counting system

Embodiment Construction

[0025] figure 1A block diagram of the axle counting system 1 according to the invention is shown very briefly. The axle counting system 1 according to the invention comprises a counting point 3 with an ISDN modem 4 and an axle counter evaluation unit 6 with an ISDN modem 7 . For example, count point 3 may be a Zp30H or Zp30CA-2 type count point. The ISDN modem 4 of the counting point 3 is used to transmit the counting point message 8 , ie data containing or representing information about the counting pulses, to the ISDN modem 7 of the axle counter evaluation unit 6 via the B1 ISDN channel 9 of the ISDN line 10 . The latter are marked with arrows in the figure. Counting point 3 transmits monitoring bit sequence 12 from ISDN modem 4 of counting point 3 via B2 ISDN channel 13 of ISDN line 10 to ISDN modem 7 of axle counter evaluation unit 6 . The transmission of the monitoring bit sequence is marked with another arrow in the figure. As monitoring bit sequence 12 , a constant ...

Abstract

The invention proposes a method for monitoring the information transmission between a counting point (3) and an axle counter evaluation unit (6) of an axle counting system (1) in a railway network and an axle counting system implementing the method . In this method, information is transmitted from the ISDN modem (4) of the counting point (3) to the ISDN modem (7) of the axle counter evaluation unit (6) via the ISDN channel (9) of the ISDN line (10). The monitoring bit sequence (12) is transmitted by the ISDN modem (4) of the counting point (3) via another ISDN channel (13) of the ISDN line (10) to the ISDN modem (7) of the axle counter evaluation unit (6), And a transmission fault in the monitoring bit sequence (12) is monitored by the monitoring module (14), preferably by the axle counter evaluation unit (6).

Description

technical field [0001] The invention relates to a method for monitoring the transmission of information between counting points of an axle counting system and an axle counter evaluation unit in a railway network, and to an axle counting system for implementing the method. In this method, the information is transmitted from the ISDN modem of the counting point to the ISDN modem of the axle counter evaluation unit via the ISDN channel of the ISDN line. The invention is particularly suitable for the preventive diagnosis of cable failures of the ISDN connection between the axle counter evaluation unit and the counting points connected to it, in order to reduce delay times of train services on the railway network. Background technique [0002] In railway signaling systems, electronic axle counting systems (axle counters) are used in order to monitor track sections. Such an axle counting system comprises at least one counting point with two rail contacts and an evaluation unit (a...
