The accompanying drawing explanation
Fig. 1 is that verification method of the present invention is carried out the applicating flow chart of checking to the station data.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, whole verification method can be divided into three layers: data Layer, checking layer and resultant layer.At data Layer, take plane layout of signals as basis, generate the station data with data modeling tool, comprise Directed Graph Model, topological structure model, route interlocking table and route formula etc.; At the checking layer, the station data importing that will write the corresponding rule base of station data model and data modeling tool generation based on script, in data validation tool, is carried out checking; In resultant layer, generative grammar audit report, validity report and figure checking report, at this moment can feed back to data modeling tool again by the checking report, revises the station data model; Repeat above step, until the data of data verification report are errorless.
Above data model comprises Directed Graph Model, topological structure model, route interlocking table and route formula.
Wherein, Directed Graph Model is a kind of data model that plane layout of signals is generated in conjunction with the digraph relative theory.The structure of Directed Graph Model is: the starting point kilometer post, the terminal kilometer post, beginning end-point data (title, type, track switch trend etc.), end point data (title, type, track switch trend etc.), sector data ((title, the starting point kilometer post, the terminal kilometer post), (title, the starting point kilometer post, the terminal kilometer post) ...), teleseme data ((title, the place kilometer post), (title, the place kilometer post) ...), its rule description mainly comprises: the terminal kilometer post is greater than the top kilometer post, all the time hold type to be necessary for track switch, the track switch trend is necessary for one of its inherent type, sector data is arranged and is occurred according to fixed form, in sector data, the terminal kilometer post is greater than the top kilometer post, arrange and occur according to fixed form in the teleseme data, device type must be consistent etc. with topological model, with script by above-mentioned rule format.
The topological structure model is by the plane layout of signals networking, usings teleseme, track switch and section as the node in network, with line, to each node in network, realizes interconnected.The topological structure model is a model independently not generally, but and device data as a global existence, but this does not affect the checking to the topological structure model.The rule description of topological structure model is as follows: node type (teleseme, section, track switch) is meaned with A, B, C respectively, the connection up and down of each node all exists, the circuit terminal replaces with DESTINATION, connect and must exist for the track switch equipment side, the interconnected of node on parallel lines can only be CC, CA (AC)/CB (BC)/AB (BA)/AA/BB can not occur.With script by above-mentioned rule format.
The structure of route interlocking table model comprises: type, all the time end signal machine, conflicting signal machine, determine antiposition track switch, route section, invade the limit section, approach section, protection section etc.Route interlocking table look-up rule dependency is in traditional making route interlocking table rule.
The route formula be take the route interlocking table model as basis, and the point that relevant device in the route interlocking table is monitored connects with logical operator.Rule description is as follows: AND and OR can not appear in the point of two neighbouring device supervision simultaneously, cluster tool in the route formula must be under the jurisdiction of the cluster tool in the route in corresponding route interlocking table, the route formula should meet the rule for its setting, timing etc.With script by rule format.
The technology of employing based on the script rule base makes whole method to data more strict checking efficiently from the grammer to the semanteme, effectively guaranteed the validity of data, improved work efficiency; The unified different pieces of information model of formulating and the Different Rule adopted for different models, can meet the checking requirement without making too large change for the data between different stations, improved work efficiency; Whole verification method has guaranteed availability, the safety and reliability of data plane.
