Fig. 1 is the structural representation of the multi-functional survey line device of the utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, the multi-functional survey line device of present embodiment comprises the master, from the survey line device, main, from measuring head and Straight-Through Cable I, Straight-Through Cable II, main, pass through Straight-Through Cable I respectively from survey line device (model is selected NS-468 for use), Straight-Through Cable II and master, from the corresponding connection of measuring head, described master, match from the specification of measuring head, wherein, described master, be respectively a pair of VGA measuring head from measuring head, a pair of RS-232 measuring head and a pair of BNC measuring head, and described master, pass through Straight-Through Cable I respectively from the survey line device, Straight-Through Cable II presses standard and described each master of EIA/TIA568B, from the corresponding connection of measuring head.
As shown in table 1 is the color and the corresponding numbering thereof of each bar line in the netting twine.
Table 1
| Reference numeral | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
| Color | Orange is white | Orange | Green white | Blue | Lan Bai | Green | Palm fibre is white | Palm fibre |
As shown in table 2 is the concrete connected mode of Straight-Through Cable and VGA measuring head:
Table 2
At first, cable to be measured two ends are broken away from former tie point, the measuring head of main profile device is connected the end (starting power switch immediately) of VGA line, will connect the other end of VGA line from the measuring head of survey line device again.
If the test lamp of master and slave survey line device is all lighted by the 1-2-3-4-5-6 order, then expression is normal; If the test lamp of master and slave survey line device is lighted not according to the 1-2-3-4-5-6 order, for example: the 4th lamp of master and slave survey line device all do not work, and then represents the 4 tunnel (HSYNC) open circuit, so analogizes, and can judge then whether each road of VGA line is in open-circuit condition.
If the test lamp of main profile device is lighted by the 1-2-3-4-5-6 order, and does not work from the 2nd lamp of survey line device, then represent the 2 tunnel (Green) short circuit, so analogize, can judge then whether each road of VGA line is in short-circuit condition.
