The fundamental purpose of all these methods all, in case of emergency provides to operator and determines foundation as far as possible reliably.At this, image reliability in principle based on the comparison of two images, that is, the image provided to operator over the display and the comparison of image producing identical illustrated frame of reference.In these methods, always whole display image is checked with pixel precision.Therefore, need to check obviously larger image-region, and the possible errors in the not too important of display or even unessential image-region may stop order to be issued.
Except carrying out except background test to all images pixel, shortcoming is also mainly used for the great expense incurred that School Affairs compares.The very high SIL requirement that related to this is to individual system.Level of security SIL is defined as from SIL0 (dangerous signalling technique) to SIL4 (on signalling technique high safety) in CENELEC standard EN 50129.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of such method and concentrator station computer system are provided, it tolerates the unessential pixel error of text based figure and has higher availability in mistake announcement highly reliably, wherein, makes every effort to alap SIL requirement.
Solve the problems of the technologies described above as follows in method: when starting to operate element, from the distinctive pixel data of the element of display, produce first text data of encoding by OCR (optical character identification), and compare with distinctive second text data of element of the procedure chart of reliable status message on signalling technique.
For this reason, concentrator station computer system is used according to claim 2, wherein, be provided with frame of reference, it has retaking of a year or grade passage and logical channel, described retaking of a year or grade passage is used for when starting to operate element, first text data of encoding by OCR (optical character identification) is produced from the distinctive pixel data of the element of display, and described logical channel is for generation of distinctive second text data of element of the procedure chart of status message reliable on the signalling technique with storage railway security equipment, wherein, first and second text datas are sent to the comparer of the message source producing status message reliably on signalling technique.
In this way, operator obtains and determines foundation reliably, wherein greatly simplify safety method and tolerates unessential pixel error.System research and development cost reduces, because SIL requires to transfer to a great extent in the frame of reference as individual components.In the ideal case, only need SIL grade to be 0 for operating walk way, and according to the degree of safety of required whole system, SIL grade <4 is needed for frame of reference.In method required for protection, frame of reference only assesses the image section for the important text of shown elementary state or graphical pixel, and compared with known method, method required for protection is not obviously more subject to pixel error impact generally.Which thereby enhance the availability of whole system.Be also advantageous in that, because safe class is low, can the software of more easily replacement operation passage, and do not damage system license.
Second text data can directly be made up of the procedure chart of frame of reference in principle.But according to claim 3, the text data also can encoded as the OCR of the distinctive pixel data of element of the virtual monitor of status message reliable on the signalling technique of railway security equipment produces the second text data.
According to claim 4, between operating walk way with frame of reference, setting data is connected, and it is for will the detail of visual text over the display, and such as title, coordinate and expansion, be transferred to frame of reference from operating walk way.By reference to system from the information for element operation needed for operating walk way request, and first text data of being encoded by the OCR from the distinctive pixel data of the element of display retaking of a year or grade and the second text data produced in the logical channel of self compare, guarantee to be produced and the text shown over the display by operating walk way.
Be set according to the particularly preferred embodiment of the one of claim 5, retaking of a year or grade passage is configured to the first School Affairs of output first text data, and logical channel is configured to the second School Affairs of output second text data.According to for the common mode of order release process, by reference to system, two School Affairs are transferred to reliable message source, such as ESTW (electronics concentrator station) or ETCS (Europe control system), to compare mutually there.
