Definitions
- the invention relates to a method for Hyundaiof fenbarung in an interlocking computer system with a control channel whose adoptedsigna1e signaltechni safe state ments represent a railway safety system represent and whose output signals to operate at least one element, such as a light signal, the railway safety systems are trained and on a lay visualized as well as a control computer system for carrying out the method.
- Hi-Fi operations on the control computer system it is necessary to ensure that the basis for the decision-making, i. H . the Meldebi Id on the display, which is displayed to the operator, the actual state of egg egg railway safety system corresponds.
- the primary purpose of the Hi-1 control is to provide the operator with the most secure basis for detection in critical situations.
- prin- ciple 1 is based on the comparison of two characters, namely the display on the display, which is made available to the operator, and the frame of a reference system, which produces the same representation.
- an operating channel and a reference channel are provided for this purpose.
- These computer systems process the information of the egg railway safety system, which represents a safe reporting source, which is probably an ESTW electronic station.
- the control channel and the reference channel are identical in terms of their input signals and used algorithms. If the signal processing is error-free, the reference image of the reference channel and the status ID of the operating channel match. In order to establish this match, checksums are made in both channels and, as part of the Hi 1 operation, sent to the safe message source for comparison.
- the complete display bi id. Is checked pixel-precise. It will follow a significantly larger image area than necessary and possible errors in a less relevant or even irrelevant display area of the display can prevent a command release. In addition to the background test of all of the bi-id pixels, it is above all the outstanding result for the checksum comparison. Damaged there are very high S IL requirements for the individual systems.
- the SIL safety levels are technically not safe in the CENELEC standard EN50129 from SIL 0 - si - up to SIL 4 - signal technical. highly secure - defined.
- the object of the invention is to provide a method and a computer system of the generic type which tolerate errors in the case of a highly reliable error definition and have a higher availability, whereby as low as possible SIL requirements are to be striven for.
- the object is achieved by optically coding coded elements, in particular QR - Quick Response coded, element specific pixel data of the display and initiating the operation of the element, and reading the data of a process abbreviation of the signal technically To be compared to other conditions.
- the invention is also achieved with an interlocking computer system in which a reference system with a feedback e1a1 for reading optically encoded, in particular QR-quick response encoded, element-specific pixel data of the display Introduction of the operation of the element and a logic channel for generating a Prozeßabbi 1des the signa1 technically safe status messages of the railway safety system is provided hen hen, the remind1esekana1 and. the logic channel are connected to a comparator.
- the operator obtains a secure basis of disclosure, in which the security procedure is substantially simplified and tolerant of unreal pixel errors compared to the known solution with the complete readout of the bi-annual menu and the retroactive calculation into a process alphabet claimed method wesentl I simpler, since not the entire Bi 1dleinha11 is completely recalculated, but only the aktuel len state changes opti cal way, preferably via QR codes, machine-readable over and will be tightened.
- SIL level of 0 is required via the control channel, and a SIL level of less than 1 s4 for the reference system, depending on the required safety of the overall system.
- Pixels evaluates the process is overall much less prone to Pi xel error a1 s the known method. This increases the availability of the system.
- Another advantage is that the software of the control channel can be exchanged more easily because of the low safety level without endangering the system approval.
- the function of the operator station has to be extended only slightly for the output of the state changes in the form of QR codes. However, it is also possible to keep the operator station unchanged and to display the QR code on a separate output device.
- the return channel for issuing first check sums and the logic channel for outputting second checksums are configured.
- the two checksums are transmitted by the reference system in the manner normally used for the command process to the secure reporting source, for example an ESTW electronic station or an ETCS European Train Control System, in order to be compared there with one another ,
- the invention will be explained in more detail with reference to a figurative representation.
- the figure shows wesentl Ie building groups of a Stel Itechniksrechnersystems invention.
- an operator station computer functioning as a 1 s operator channel 1 and a reference system 2 are provided, which differs greatly. I use algorithms for very different tasks.
- the control channel 1 generates a process image 4, which from a technically secure point of view of a railway safety system 3, at the center of a proj ected interlocking logic, which serves to visualize a corresponding text and / or graphics display on a display 5 becomes .
- the Hi 1 fs condition is sent to the plant through the control channel 1.
- the color display 1 displayed on the display 5 is checked by the reference system 2 with respect to pixel errors and errors in the signal processing in the operation channel 1.
- the service-specific state changes first become QR-Quick
- Re c k 1 esekana 1s 8 of the reference system 2 read out.
- the corresponding bi-id pixels are converted in a computer 9 into a machine-readable two-step process image Id. 10, which makes possible a check-sum generation.
- a second checksum is formed via a process section 1d 12 of this logic channel 11.
- the process image 1d 12 becomes - like the operating channel the process image 1d. 4 - formed directly from the projected interlocking logic and thus directly from the signa 11echni cal safe state conditions 1Phygen the Eisenbahntechnischsanage 3.
- the checksums of the return unit 1s 8 and of the logic channel 11 are compared by a comparator 13, which preferably is part of the sata-secure area of the third unit. It can only be assumed that the signal processing in the operating channel 1 has proceeded without errors and the display 5 in the relevant regions 1 is free from errors, so that the command can be released. In this safety procedure, the pixel areas of the display 5 which are not required for the momentary operating action are ignored, which results in a high availability of the overall system.
- the operating channel 1 secured by the reference system 2 can have a safety level SIL 0.
- the scope of functions with SIL greater than 0 is limited to the reference system 2 and can With reference to the overall system, it can be clearly reduced compared to the known embodiment.
