Microcontroller in the monitoring station, OTDR module, optical switch alarm part are concentrated in the same equipment at the scene, all control commands are all controlled the program control conversion that optical switch alarm part is carried out arbitrary optical-fibre channel by central processing unit by the bus and the parallel port data wire that provide on the mainboard in the module, and control OTDR tests, thereby obtain the curve data of monitored optical fiber, the message transmission rate height.And its serial ports, parallel port connect simple, thereby rational in infrastructure.
Said program control optical switch is connected with mainboard by its interface card, the circuit of interface card can be in the utility model: signal input part connects multichannel by the photoelectricity isolated tube and reads integrated package A7, its output connects the mainboard parallel port, meet another integrated package A6 (74HC244) simultaneously, this integrated package outputs to program control optical switch; Mainboard parallel port data output end meets two data and logical earlier integrated package A1, the A2 that control and reset of optical switch that control to output of optical switch data and control alarm signal, the output of one of them connects the 1st, 19 pin of integrated package A6, A7 by decoder A5,1,2,6,8 pin of mainboard parallel port meet the integrated package A3 that is used for the cascade optical switch, and its output meets integrated package A5 by band switch 18,19 pin; Be connected to anti-jamming circuit between band switch, mainboard data wire and the ground wire.
For convenient measurement to multi-channel optical fibre, be connected to program control optical switch expansion card on another parallel port of mainboard, its circuit is identical with the circuit of above-mentioned interface card.
In addition, for guaranteeing the utility model reliability of operation, the electric board of storage running supervisor has been installed on its mainboard.
And, for easy to use, the COM termination touch-screen of mainboard, its data wire connects touch-screen by display card.
The utility model has also been installed the network interface card that is connected with mainboard on base plate, utilize Ethernet interface on it etc. to be connected with external communications equipment.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the line map of alerting light switch interface card;
The utility model comprises shell, and base plate and mainboard are arranged in the shell, and data acquisition OTDR card is installed on the base plate, the output termination light output OTDR module of this card.Also have network interface card, display card on the base plate, they all are connected with the data/address bus of mainboard with the OTDR card, and wherein display card connects touch-screen.Electric board is installed on the mainboard; The LPT1 mouth of mainboard connects optical switch alarm mouthful card, is inserted with program control optical switch on it; Mainboard LPT2 connects alerting light switch interface card expansion mouth.Wherein, the circuit of alerting light switch interface card is: signal input part connects multichannel by the photoelectricity isolated tube and reads integrated package A7 (74HC244), and its output connects the mainboard parallel port, meets another integrated package A6 (74HC244) simultaneously, and this integrated package outputs to program control optical switch; Mainboard parallel port data output end meets two data and logical earlier integrated package A1, the A2 (74HC373) that control and reset of optical switch that control to output of optical switch data and control alarm signal, the output of one of them connects the 1st, 19 pin of integrated package A6, A7 by decoder A5 (74HC154), 1,2,6,8 pin of mainboard parallel port meet the integrated package A3 (74HC138) that is used for the cascade optical switch, and its output meets integrated package A5 by band switch 18,19 pin; Be connected to the anti-jamming circuit of forming by three 74HC02 integrated packages between band switch A8 (SW-DIP8), mainboard data wire and the ground wire.
