Formula 2M signal-testing apparatus inserted by a kind of collection, and it is particular in that: include isolation interface plate,
This isolation interface plate is installed with 16 L9 plugs, these 16 L9 plugs (8)
One end is each provided with a light emitting diode, and these all light emitting diodes pass through signal connecting line respectively
Being connected with signal processing module, this signal processing module is connected with at least 2 status indicator lamps the most respectively.
Wherein signal processing module uses single-chip microcomputer.
Wherein signal processing module is connected with 3 status indicator lamps respectively.
The beneficial effects of the utility model are, accurately whether can judge transmission equipment 2M signal break-make
Normally, while sending and receiving end slogan is the most correct so that testing efficiency is greatly improved, and apparatus structure
Simply, it is easy to accomplish.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of signal testing unit in this utility model；
Accompanying drawing 2 is the structural representation of test result display unit in this utility model.
Detailed description of the invention
As shown in Figure 1, 2, this utility model provides a kind of collection and inserts formula 2M signal-testing apparatus, by
Signal testing unit and test result display unit composition, wherein signal testing unit includes isolation interface
Plate 9, (L9 type adapter, should to be installed with 16 L9 plugs 8 on this isolation interface plate 9
Product, and can be with for connecting radio frequency coaxial-cable in the loop of rf of communication equipment and radio instrument
Meet the product that IEC169-13 specifies to exchange mutually), each pacify in one end of these 16 L9 plugs 8
Equipped with a light emitting diode 7, these all light emitting diodes 7 are respectively by signal connecting line 5 and survey
The signal processing module 4 of test result display unit connects, this signal processing module 4 the most respectively with at least
Two status indicator lamps connect.
Wherein signal processing module 4 uses single-chip microcomputer, and signal processing module 4 respectively with three shapes
State display lamp connects.
Using method of the present utility model and operation principle be: formula 2M signal inserted by collection of the present utility model
Test device divides two parts to form: signal testing unit, test result display unit.Signal testing list
Unit is for 16 system digits blocks, uses 16 L9 plugs 8, according to digital wiring list
16 L9 plugs 8 are arranged in order and are fixed on isolation interface plate 9 by unit's 2M joint clearance,
Use 16 light emitting diodes 7 as the signal lamp of each L9 plug 8, be spot welded to L9 respectively
On plug 8.In test process, use this isolation interface plate 9 collection to be inserted to number and join unit, can pass through
The display 2M signal testing result of light emitting diode 7.And test result display unit is by 16
L9 plug 8 tests the signal of telecommunication (representing the on-off model of switching) arrived by signal connecting line 5
It is sent to signal processing module 4, such as single-chip microcomputer, uses corresponding algorithm routine, it is judged that test knot
Fruit also gives display.Wherein, green indicating lamp is bright, represents equipment 2M signal break-make, transmitting-receiving port
Number the most normal；Yellow indicator lamp is bright, represents that equipment 2M signal break-make is normal, but transmitting-receiving port order
The most right；Red led is bright, represents that the output of equipment 2M signal exists situation about interrupting, need to carry out event
Barrier investigation.Or with two display lamps, it is set to the bright expression of green indicating lamp normal, and red led
Bright expression is abnormal.
Embodiment 1:
In FIG, first 16 light emitting diodes 7 are spot welded to respectively 16 L9 plugs 8, then by 16
L9 plug 8 is gradually fixed on isolation interface plate 9.When carrying out 2M signal testing, will insert with L9
The isolation interface plate 9 of 8 docks with " U " the type ring interface on digital wiring unit, by 16 luminescences
Diode 7 shows break-make and the sending and receiving end slogan of 2M signal.
In fig. 2, surveyed for light emitting diode 7 signal of telecommunication is transmitted to signal by signal connecting line 5
Reason module 4, and use insulation crust 6 that signal connecting line 5 and signal processing module 4 are fixed bag
Dress, only need to reveal greensignal light 1, amber lamp 2, red eye 3.Letter
Number processing module 4 processes according to following principle: generally, SDH optical transmission device is joined in numeral
Distribution order on line unit is that 1#, 3#, 5#......15# totally 8 interfaces are that equipment sends out the 2M signal of telecommunication,
2#, 4#, 6#......16# totally 8 interfaces are that equipment receives the 2M signal of telecommunication, when carrying out signal testing, if
Light emitting diode 7 all light of odd number seam, then signal processing module 4 exports greensignal light 1 (point
Bright) signal, represent that test result is the most without exception；If 8 telecommunications that signal processing module 4 receives
With the presence of even number interface signal in number, then signal processing module 4 exports amber lamp 2 (lighting) letter
Number, represent that optical transmission device 2M signal break-make is normal, but signal transmitting and receiving interfacing order mistake, need to be according to
Light emitting diode 7 display is adjusted；If the signal of telecommunication that signal processing module 4 receives is unsatisfactory for 8,
Then output red signal lights 3 (lighting) signal, represents that 2M signal testing does not passes through, there is equipment 2M
The situation that signal output is interrupted, need to carry out defect investigation.
