Abstract

Assorted data elements (STI-ST4) are integrated into an element connection plan at the junction points of data elements (W1-W3, FSZ1-FSZ3) for adjacent track elements (w1-w3; s1-s3) in a track plan. Said assorted data elements process track monitoring information (GFM) for the track elements of the respective adjacent data elements. They also test whether conditions for the cancellation of the individual track elements are met. If this is the case, they cause route information in the data element of the track element for which said conditions have been met to be deleted.

Description

Unit connection system for electronic signal buildings

The invention relates to a unit connection system according to the preamble of claim 1 . This unit connection system is known from DE 43 20 574 A1.

In this above-mentioned document, a device for processing track functions in an electronic signal building is proposed, wherein, in the signal building, each track idle section is allocated a separate track section unit according to the processing logic, which is used for all relevant The track unit can realize the definite track function. The programs for implementing these rail functions, especially the access interface rail monitoring and unlocking, no longer exist in the processing logic of the rail unit. Track section units are placed in the track interface of the signal building in such a way that they occupy a position in imitation of the relevant track free sections which is touched by all possible travel routes through these track free sections; thus in For each route processing involving the associated track units, these track section units are called up and interrogated for the stored monitoring signals. In the track section units, the unlocking conditions for each adjusted route are also processed, for which purpose, in addition to the own free and occupied signals, the adjacent track section units in the unit connection system are also evaluated there track segment unit. To do this, it is necessary to exchange adjacent track section units with one another. The advantage of this known device is that by calling out the idle and unlocking conditions from the data units of the track units and assigning them to each track section unit, especially in the case of a plurality of jointly monitored track units, and wherein it is necessary to assign each track unit The handling of this unlocking is greatly simplified compared to an arrangement in which track units distribute track monitoring signals. But the problem is that the track section units are always arranged in the unit connection system in such a way that they are actually touched by all possible travel routes through the relevant track section; Two or three track section units must be set for a jointly monitored track unit. The problem also lies in the communication between adjacent track section units in the unit connection system for the unlocking function; the track free signals of adjacent track section units are either sent via the associated track unit or by address according to the track layout transmission. Both of these tie down computer power.

The object of the invention is to improve the unit connection system described in the preamble of claim 1 in such a way that it is possible to cancel the individual arrangement of track section units at the center of a track unit arrangement, and to eliminate the need to pass through adjacent track sections. The track unit data groups between the segment units transmit the track free and occupied signals of these adjacent track segment units.

The object of the invention is achieved by the characterizing features of claim 1 . According to it, the track section unit assigned to each track unit will be replaced by the unit assigned to the junction of adjacent track units. These units will each be supplied with track monitoring signals by two adjacent track units and verify unlocking conditions. According to the solution of claim 2 , when the unlocking condition is fulfilled, these units bring about an unlocking of the associated track unit in a particularly advantageous manner by clearing the route information in their associated data set.

The invention will be described in more detail below using an exemplary embodiment shown in the drawing. The accompanying drawings indicate:

Figure 1: Fragment of a track layout diagram,

Figure 2: Structure of a related unit connection system constructed according to the prior art, and

Figure 3: Unit connection system with additional data sets between logical units of adjacent track units according to the invention.

Figure 1 shows a track diagram of a railway facility in fragments. The track diagram includes three switches w1 to w3, a track section between the switches w1 and w2 that are secured by light signals s2 and s3, and a track section that is connected to the top of the switch w1. The light signal s1 of this section can be seen.

Figure 2 shows the track diagram in data units, as is commonly used in an electronic signal building for handling track functions. The electronic signal building is preferentially a signal building that works according to the principle of the track plan; however, the signal building can also work according to the principle of the locking chart, where the call-up (Aufgriff) of the individual data units may differ from the signal of the track plan The call-out situation of the building. Data sets W1 to W3 are assigned to the three switches w1 to w3 and data sets FSZS1 to FSZS3 are assigned to the signals s1 to s3 ; the notation FSZ here stands for the travel distance unit—starting point/end point. These data elements contain, as data sets, characteristics of the geographical configuration of the relevant track elements relative to one another and describe their current operating state with respect to the access load. The connection lines between the data units together with the data units form a unit connection system, in which the data units in the signal building are arranged sequentially in the same way as the corresponding track units of the railway equipment. These connection lines are not absolutely the lines between the individual data units, but mainly refer to a communication link which can be implemented instantaneously and preferably in an address-oriented manner. The track free signal GFM of the associated track unit is shown below the data unit. In particular, direct current circuits and shaft counters are used as track-free signaling devices. Each track vacancy signaling device transmits an occupancy or vacancy signal of the track section it monitors to each associated data unit, depending on the situation on site. For the track section laid between the switches w1 and w2, the monitoring signals are transmitted not only to the data unit FSZ S2 but also to the data unit FSZ S3. In a conventional electronic signal building the track monitoring signal is evaluated in the data unit. Based on the monitoring signals of the own distance traveled unit and the monitoring signals of adjacent distance traveled units, the conditions for unlocking the relevant unit are checked, for example, in the individual data units. Depending on the order in which they are arranged, the track units that are passed successively in this order are thus displayed as occupied and then become free again.

Especially in the case of a plurality of commonly separated track units, it has always been necessary to set the track monitoring signals assigned to these separated units multiple times in each track unit of the jointly separated track section, that is, the track monitoring program Unlike track units that are not co-monitored. This makes the whole unlocking procedure unclear. It is therefore desirable that all track units or data units of a railway installation be handled in exactly the same way. The unit connection system shown in FIG. 3 can do this.

Firstly, FIG. 3 also shows the data units of the switches and signals already known from FIG. 2 ; they have the same designations as the corresponding data units in the unit connection system shown in FIG. 2 . Ad hoc data ST1 to ST4 are inserted at junctions of data units of adjacent track units in the track diagram, so-called junction units. As can be seen from this figure, the data units FSZ2 and FSZ3 of the jointly monitored track section between the signals s2 and s3 at the junction are also allocated to two ad hoc (gesondert) data units ST2 and ST3, That is, these commonly spaced track units are handled in the same way as individual spaced track units. These ad hoc data units receive the track free and occupied signals sent to them from the track monitoring device of the track unit for the adjacent data units on the unit connection system, and use the transmitted free and occupied signals to check whether The predetermined unlock condition has been met. As a result, the sequence of free signals towards the front after occupation is determined and evaluated for track units of adjacent data units on the unit connection system. If an ad hoc data unit can determine, by virtue of the order in which the track unit is occupied and free, that the unlocking condition for a data unit adjacent to it in the unit connection system is met, then in this data unit will cause Elimination of existing route information. This unlocking process is therefore caused by the data units assigned to the track unit and now only takes place in ad hoc data units, for which purpose the track free signal of the associated track unit is supplied to these ad hoc data units.

As can be seen from FIG. 3, the construction of the unit connection system according to the invention is independent of how many track units are to be jointly monitored, it always follows one and the same way. By setting ad hoc data units for individual or jointly monitored track units at the junction of the data units, the track monitoring signals of the track units used for adjacent data units in the unit connection system can be processed and their unlocking conditions can be checked . The track monitoring signals are to be transmitted to these dedicated data units by a direct path without intermediate switching branch units. There can be any number of data units used to jointly monitor track units between adjacent ad hoc data units in the unit connection system. Precisely for those sometimes unclear track connection situations, the unit connection system according to the invention, by using and inserting joint units at the joints where data units are normally provided, creates Preconditions for all track units and completely independent of whether these track units are individual or a plurality of commonly spaced apart.
