The possible error detection, location and storage without additional technical effort enables a fast suppression and thus an increase of the plant availability. The latter, the simple adaptability to the specific applications, the use of only a microcomputer, the absence of the use of special components, the saving of copper and the reduction of the enclosed space are the main economic advantages of the invention.

Title of the invention

Device for automatic transitional protection

Field of application of the invention

The invention relates to an electrical system for mutually securing rail and road traffic at level crossings (path crossing). The required control functions are - as before - triggered by the moving train or in part by the operator.

Characteristics of the known technical solutions It is known that the level crossing of rail and road traffic (path crossing) u.a. secured by electrical systems (roadside protection systems), the train-operated or partially manually and partially zugbedient work · The control functions are triggered by the moving train or partially by an operator and in a corresponding relay circuit as a control device to signal and possibly * Barrier control oa processed. This relay circuit mainly uses signal relays specially made for railroad safety technology and thus requires technology-specific production capacity 'copper' (relay windings) and a relatively large enclosed space. • Errors occurring in these systems are usually automatically detected, as long as they reduce the safety or availability of the system monitoring operation

communicated. This saramel message, however, does not allow differentiation or location of the fault and thus does not provide significant assistance to the troubleshooting personnel. However, since the interference suppression work can be very time consuming due to the location of the signals and track switches, these systems are sometimes supplemented by six-fold recorders can identify faults on a maximum of six system components (ζ · Β · track switching devices) ·

The switching functions with a safety function performed by the relay circuit according to the principle of redundancy · The adjustment of the control device of the system at the respective specific application (station or haul segment, number of tracks, etc. _e) is carried out by partially extensive planning work with then corresponding complicated circuit wiring · üra this effort has been proposed several times a functional group structure of the control device

In the past, electronic partial or total solutions of the control device have been proposed on various occasions «. However, these are based on case-specific Yerdrahtung and thus require at least as large project planning and "wiring costs as the relay systems ·

Explanation of the essence of the invention

The object of the invention is ₉

i "the information (input signals) coming from the signals and track switching means and, if applicable, other operating and safety devices in a microcomputer (belonging to the control device) and partially redundantly in a corresponding circuit arrangement (belonging to the control device) and from this the required control values To develop (output signals) for the signals and, if necessary, barrier drives and other safety devices;

2. To allow the adaptation of the control device to the specific application without significant time and effort;

3 "by automatically recording all the major technical faults of the system without additional technical equipment, checking their durability, as well as their storage and display to simplify the filtering and thus speed up, so that increases the availability of the system.

According to the invention, this object is achieved by the fact that the information E arriving from the signals and G-switch circuit means and possibly other operating and securing devices is linked together in a microcomputer MH and from this the required control values A _Q or Agj for the signals and if necessary for the barrier drives and other safety devices. The output signals with safety responsibility Ago are thereby formed independently of the microcomputer in a redundant logic circuit LS from the input information E. In a corresponding logic circuit VS arises in accordance with the output signals Ag. and AgP the output required for control with safety responsibility Agj

2. by targeted activation of corresponding program segments and insertion of the required parts of the matching circuits APSp or APS. and the logic circuit LS the

Control device SE in a simple manner to the specific application is adaptable. For this, the adaptation, logging and linking circuits must be modular in structure and thus changeable and extensible§

3. The microcomputer detects the technical errors occurring in the system, stores consistent (reproducible) errors with fault location and, if necessary, displayed via a diagnostic device DG the Entstörungspersonal The computer-internal management of a fault statistics is possible »

Since the use of relays is dispensed with, no special fuse-related components (signal relays) are required, copper (relay windings) is saved and the vascular system of the control device is reduced.

Exemplary embodiment ►

The invention will be described with reference to an embodiment for a simple application; FIG. 1 shows the corresponding schematic representation »

In the basic position, the path crossing for the traffic is passable; This means that road signals are switched off and, if necessary, existing barrier trees are open. If monitoring signals are present, they inform the rail traffic about the unsecured state of the way transition. If a switch-on pulse as an input signal reaches the microcomputer via the adaptation circuit APSg, then it becomes a control value A _Q for switching on implemented all road signals and closing any existing barriers trees and the adjustment circuit APS. output. In systems with monitoring signals, these inform the rail traffic about the secured state of the path transition as soon as all road signals block the path transition. This signal is output by means of a corresponding output signal A ₀ via the matching circuit APS. This output signal Ag results from the output signals A _S j and A ₃₂ developed in the microcomputer MR and in the logic circuit LS and connected in the linking circuit V _S with full reception of all the input signals which inform about the blocking of the road signals are formed.

If the Aussehaltimpulse complete as input signals via the matching circuit APS _E in the microcomputer IvIR and in the logic circuit LS, v / erden the output signals A ₀ .. and Ag2 for switching off the road signals and for opening the existing barrier trees formed in the logic circuit VS to the output signal A ₃ combined and output via the matching circuit APS ,,.

If monitoring signals are present, then these are switched off in the same way (depending on track and direction) and the road signals are switched off. If one or more safety or availability-reducing errors occur during the operation of the system, these are recognized by the microcomputer and, as long as they are stable, stored * The fault clearance personnel can immediately inform themselves about the type and location of the fault by means of the diagnostic device DG and eliminate it quickly and purposefully. The adaptation of the system to the specific application (eg station or route area, shunting, track number, number of road signals, available signal dependency usv / ·) is done by generating the software (activation of the required program blocks) and inserting the required blocks for the matching circuits APS ^ and APS. as well as the logic and logic circuits LS and VS. "Changes are likewise possible in a simple manner.
