Related information final after parsing is as shown in Figure 2:
Connect from Fig. 2 device void loop figure it can be seen that all signals that device " No. 1 220kV line segregation merges unit A set " to " No. 1 220kV line segregation route protection A set " sends all are received by " No. 1 220kV line segregation route protection A set " " 10-A " port.Device " No. 1 220kV line segregation merges unit A set " can be derived and must there is actual physical connection loop with device " No. 1 220kV line segregation route protection A set ", and the port " 10-A " of " No. 1 220kV line segregation route protection A set " should be the one end in this article of actual physics loop.
Three, physical loop information analysis:
AutoCAD drawing provides the annexation of complete all secondary device physical loop of standing, and it is generated by the configuration of special configuration instrument.The physical connection between the secondary device difference according to networking mode and connected mode, it is divided into two class connected modes, one class is the direct-connected mode of device port, direct-connected mode according to whether through light partition for joining directly through light and joining without light direct-connected, another kind of for net connection mode, namely two associated apparatus carry out data exchange through same switch simultaneously, but do not have being directly connected between device port between device.The reading method of three kind connected modes, the publish picture mode of respective drawing and respective type drawing is described below.
(I) device physical port connected mode
Joining direct-connected through light: if distant between device, the light of this timer and affiliated screen cabinet is joined and is attached, then the light between two screen cabinets joins use optical cable welding, the physical loop of composition connection, as shown in Figure 3.
Join without light direct-connected: when distance between device is shorter, directly use optical fiber to connect, as shown in Figure 4.
When being connected by networking between device, between associated apparatus, port is without direct correlation relation, but, the two is connected simultaneously to optical fiber switch, carries out data exchange through switch, as shown in Figure 5.
(II) corresponding drawing resolves
The parsing of direct-connected optical fiber distributing figure is joined through light:
Optical fiber distributing figure depict device port with screen cabinet light join, two screen cabinets between light join between connected mode, as shown in Figure 6.Wherein go up three behavior Table Header information, for the link information of each screen cabinet terminal from fourth line, and every one custom entities of behavior.The behavior example being " 1 " with fibre core sequence number; this row have recorded the link information that light matching terminal is " 1J-1F-1 "; this terminal inner is connected as " 10-B " mouth of " No. 1 220kV line segregation route protection A set "; and fibre core color is blue; sleeve pipe color is blue, and the optical cable connected is numbered " G01 ".
In like manner, the optical cable of " G01 " is numbered for optical cable and should there is opposite end screen cabinet, it is possible to read the corresponding port link information of opposite end screen cabinet.It is illustrated in figure 7 opposite end screen cabinet link information.
For same fibre core under optical cable, his the sleeve pipe color in different light figures should be distinguished corresponding identical with optical fiber color.
One end light matching terminal that the optical fiber that optical cable numbering is all " G01 ", fibre core sequence number is " 1 " connects is " first set 220kV line segregation protection cabinet "This light matching terminal interconnection apparatus port is the port " 10-B " of " first set 220kV line segregation route protection A set ", and the light matching terminal that the other end connects is " first set 220kV line segregation convergence control cabinet "This light matching terminal interconnection apparatus port is the port " 6-B " of " first set 220kV line segregation merges unit A set ", therefore can obtain actual physics loop, as shown in Figure 8:
The parsing of the device port figure that the device joined without light is direct-connected:
The device port information joining connection without light is stored in device port figure, each port connecting line is a custom entities, this end connection device of this entity record, local terminal connectivity port, to end connection device, and connectivity port, opposite end, as shown in Figures 9 and 10.
In like manner; read the link information comprised in the device port connection figure of end device; thus; can draw there is annexation between the port " 6-A " of device " No. 1 220kV line segregation merges unit A set " and the port " 10-A " of device " No. 1 220kV line segregation route protection A set ", as shown in figure 11.
