Marginal data
Embodiment
The present invention will be described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, designing cable path of nuclear power station provided by the present invention comprises the steps:
Step S1 sets up the matching relationship of cable and crane span structure.
According to the requirement of cable laying criterion, begin the initial stage in cable laying work, just need to set up the matching relationship of cable and crane span structure.This matching relationship is with the type of cable (such as middle pressure, low pressure, control etc.), serial colour code (A CO, A OR, B GR, DA BK, G1 YE, G2 BL, G3 RE, G4 BR, P1 PU, P2 TU etc.), with the type of crane span structure, serial colour code, set up that relation table one to one realizes.When cable laying, cable and crane span structure need to be followed this one to one relation table, have so just guaranteed that cable laying is in the crane span structure that meets the requirements.Simultaneously also can formulate the situation of some exceptions according to the specific (special) requirements at some factory building, with reliability and the accuracy of abundant assurance cable laying.
Step S2, the foundation of device data and cable data.
Before setting up cable data, need to be with equipment modeling in database at cable two ends.The information such as the title of equipment, coordinate, room of living in just are based upon in modeling process in the database, with the form storage of table.Then according to the cable inventory, data with cable, comprise title, the type of cable, serial colour code, cable characteristic code, starting point room, play point device, terminal point room, end device and some remark informations (positive pole, negative pole etc.), be based upon in the database, store with the form of table equally.The invention provides the method for two kinds of foundation:
I) designer manually sets up in software.Namely according to the every terms of information of cable, manually typed in by the designer.The method is labor intensive relatively.
II) designer will meet the cable inventory EXCEL file of software requirement, by interface cable data be imported in the database of software.This method need to guarantee that the EXCEL file of cable inventory meets software requirement, and every data of cable: room, equipment etc., keyed in database.This kind method efficient is higher.
Step S3, the foundation of the cable terminal device points of proximity.
According to the deployment scenarios of equipment, for the terminal device of cable arranges the rational points of proximity, as the starting and terminal point in the cable trace design process.The points of proximity can be certain nodes near the master tray of equipment, also can be time pallets.And can add hole in the points of proximity, with the correctness of abundant assurance cable trace.The rational points of proximity need the designer to pass through analysis to equipment layout and pallet figure, guarantee that the rationality of cable laying and the feasibility of construction further determine.Certain node on the master tray refers to some key points on the master tray, determines that by the locus of describing these key points the locus of main crane span structure and spatial form change.Inferior pallet refers to the pallet that the design phase locus is not clearly determined, usually is present in narrow room, position between master tray and the equipment.Apart from node or the inferior pallet on these nearest master trays of equipment, namely may be defined as the points of proximity of equipment.
Step S4, the laying of cable.
The laying of cable is divided into automatic laying and manually lays.
The mode of automatic laying for adopting ripe Searching algorithm (for example A* (A-Star) algorithm) to search cable run, automatic laying takies the system resource of a large amount of cable laying softwares, therefore in the present invention, if the designer wants to adopt automatic laying, then need to send application, ratified according to the working condition of reality by the service management person of higher level's cable laying work.So just control the working time of automatic laying, in order to avoid because automatic laying takies the reduction that a large amount of software systems resources causes cable trace design effort efficient as far as possible.
Manually lay and after the designer finishes the arranging of the equipment points of proximity at cable two ends, to carry out.System of the present invention can provide selectable path according to the network data model of having set up, and the designer selects rational path according to designing requirement.If the path is unique, meeting then of the present invention is directly laid to the path the place, fork, then selects Rational Path by the designer, until the terminal point in path again.Such system of laying only needs the designer to have the turnoff to select in the path, has improved to a certain extent designer's work efficiency.
This road is through design process, fully according to the network data model of having set up.Network data model in computer software, show as one by annexation will have living space the position main crane span structure and do not have inferior crane span structure, the hole of locus to couple together, the cable bridge network of a connection of setting up.During network data model is set up, the criterion requirement when connecting according to crane span structure, and the designer has carried out rational connection networking according to the deployment scenarios of pallet with cable tray.The present invention utilizes relevant database to make up cable bridge network, described data element adopts the table object of relevant database to store in computing machine, comprise axis table, node table, crane span structure segment table, crane span structure subsegment table, inferior crane span structure table, well table, main connection table, primary and secondary connection table, inferior connection table, make up the meshed network of a logic by the description of these table information.Be each data element in the computer system by the cable testing bridge system map with reality, and layering, classified description crane span structure, make the complicacy of the clear and realistic crane span structure of crane span structure network structure system.The patent " a kind of method of utilizing relevant database structure cable bridge network " that the specific descriptions that cable bridge network is set up can apply fors referring to the applicant same period.
When carrying out cable laying, provide the prompting path by software according to cable bridge network, owing to the rationality that the crane span structure network is set up, just guaranteed the rationality of cable trace.And because the prompting path is provided according to cable bridge network by software, behind selecting paths, cable trace namely verified by database, and this process has guaranteed the real-time verification of cable trace.As long as the cable trace design is finished, the proof procedure in path namely finishes, and has fully saved the system resource to taking in a large number in the cable trace proof procedure.This has also improved the work efficiency of cable trace design to a certain extent.
Below in conjunction with accompanying drawing 2, specifically introduce the enforcement of path design of the present invention, specific implementation method is as follows.
Accompanying drawing 2 is crane span structure logic node network diagram, and wherein, the electrical equipment of cable starting point is E1, is positioned at the 3L312 room, and the electrical equipment of cable terminal point is M, is positioned at the 3L311 room.
