DE3314702A1 - Circuit arrangement for an electronic actuating mechanism - Google Patents

Abstract

A circuit arrangement for an electronic actuating mechanism is disclosed, in which the individual travelway elements are assigned groups (GI...GIV) which contain control circuits which carry out control programs designed in accordance with the functions of the respective travelway elements and have geographic data inputs and data outputs via which they are connected to the control circuits of adjacent groups in accordance with the geographic layout of the track system. The functions of the individual groups are divided up into different sub-functions which are fulfilled by separate sub-control circuits (T1...T12). By combining the same kind of functions of various groups into specific function planes, a three-dimensional structure of the design of the actuating mechanism is produced, in which structure individual or even in each case several sub-control circuits located in a function plane or a group are combined and can be realised by means of a microcomputer (R1...R10). The junctions between the sub-control circuits are realised outside the computers by means of interface elements (SE) and within the computers by means of parameter transfers. <IMAGE>

Circuit arrangement for an electronic signal box

The invention relates to a circuit arrangement according to the preamble of claim .1.

Such a circuit arrangement is, for example, in the older one German patent application P 32 32 308.5. the used in conventional track plan signal boxes, the So-called geographical circuits that connect with each other individual control groups are here by accordingly the geographic structure of the track system replaces data connections. Central facilities like a special operating group for monitoring the operating device or a central route selection group can be used with one of the ones described in the above-mentioned patent application There is no need for an interlocking device equipped with a device. The operating elements necessary to carry out control actions are directly associated with the individual control groups assigned.

In an interlocking there are on the one hand groups that · only have to execute relatively simple control programs, on the other hand also groups with very complicated control

Programs. Such groups contain, especially if they have to be signal-technically secure, extensive Control circuits that precisely target the perceivable Function are tailored and often at minor Changes to the control program can no longer be used are. If freely programmable components are used in the control circuits, subsequent Make changes to control programs easily. But there is then the risk that with very extensive Control programs required for the actuation processes Switching times become too long, e.g. when a route with many element groups is to be set and the maximum time allowed for marking the route may not be more than 1 to 2 seconds.

The invention is intended to counteract such disadvantages, which increase with the scope of the control circuits, and is carried out by the features of claim 1 described.

The circuit arrangement according to the invention also provides to divide a signal box according to geographical aspects, a division of the individual groups after functions before. This becomes a three-dimensional Structure of the signal box created. A group then contains sub-control circuits, the individual Tei I functions assigned to this group and among each other as well as with partial control circuits from neighboring groups correspond via date ην connections. There is thus the possibility of several work processes in one Group running at the same time instead of running them in

a control circuit to do one after the other. this shortens e.g. the setting time of routes considerably. In addition, the three-dimensional structure enables of the signal box, in which the various part I functions assigned partial control circuits of the groups can be arranged in functional levels, a direct dialogue of sub-control circuits arranged in this level with each other, so that a larger number of parallel geographical interfaces between individual groups for It is available, which reduces the transmission time, especially in the case of serial data transmission.

According to claim 2, for safety-critical functions Partial control circuits doubled and the expenses be checked by comparison.

An embodiment of the circuit arrangement described in claim 3 according to the invention sees interface elements between individual sub-control circuits, according to Claim 4 also between the sub-control circuits within a group. These interface elements wall into one another converts the data to be transmitted into serial data telegrams, which (e.g. by means of a data security code) better secured against corruption on the transmission path can be transmitted as parallel data.

An embodiment of the circuit arrangement described in claim 5 relates to the implementation of the partial control circuits using microcomputers.

Claim 6 finally provides for the replacement of several partial control circuits by a computer or a multi-computer system with parallel working computers. the Interface elements between part control units are replaced by parameter transfers between individual program blocks of the computer. So that results the possibility of changing the computer configurations of the individual Groups and ultimately even the entire interlocking only after the control programs have been created optimize. This is an important advantage in the development of electronic track plan signal boxes.

Based on a figure, an embodiment of the Computer arrangement according to the invention described and his Function are explained.

The figure shows the distribution of control groups schematically GI ... GIV in partial control circuits T1 ... T12 and a possible implementation of these partial control circuits represented by computer R1 ... R10. The control groups are assigned to the control elements, which are selected from the

Accordingly, the control groups GI and GIV are signal groups, the control group GII is a turnout group and the control group GIII a track section group, its assigned Section e.g. through a track circuit its occupation status is monitored. The turnout should also contain a track circuit, its Occupation status monitored.

Levels II to V are functional levels, i.e. those in have partial control circuits arranged at these levels same or similar tasks. For example, the functions for route search and route setting are assigned to function level III. In function level IV there is lock and monitoring of the route elements ensured. In. Function level II is the train-induced route resolution and in function level V the control of Light signals L and point machines WA.

The individual sub-control circuits T1 ... T12 are over Interface elements SE with the respectively neighboring Part control circuits connected. This can be done both within a Group as well as between the groups within a functional level be the case. In principle it can also - this is not the case in the figure shown - a sub-control circuit can be connected to another sub-control circuit that is neither the same group nor the same Functional level heard. There is an interface element either from a parallel / series converter or a Series / Par a I lel converter. The one to be transmitted serially. Information can also be output via a feedback shift register and thus by means of a cyclic code be secured against falsification.

If the individual partial control circuits are operated by means of micro ' computers, so they can be used both in parallel and also be connected to one another serially via interface elements. In the case of partial control circuits, only a few Need to carry out control steps, it is also possible- - As shown in the figure for the partial control circuits
