Abstract
The utility model discloses a fault indicating optical line terminal, which comprises an optical line terminal. The power supply end of the optical line terminal is connected with a fault indicating circuit. When a power supply fault occurs in the optical line terminal, a fault indicating device can remind a person on duty of the power supply fault, the person on duty can report the fault and communication personnel can handle the fault in time to enable a substation to run normally as soon as possible.
Description
Technical field
The utility model relates to the optical transceiver that is used for optical fiber communication in the transformer station, relates in particular to a kind of faulty indication optical transceiver.
Background technology
At present, optical transceiver in the Fiber Optical Communication System in the transformer station breaks down sometimes, and as the management unit of communication apparatus, can not keep constantly again in transformer station, the operator on duty of transformer station just can not in time find fault, and in a single day power failure takes place in optical transceiver, will cause substation data can't upload scheduling, brings very big hidden danger for the normal operation of transformer station.
The utility model content
The purpose of this utility model provides a kind of faulty indication optical transceiver, can remind the person on duty that optical transceiver breaks down in time.
The utility model adopts following technical proposals: a kind of faulty indication optical transceiver, comprise optical transceiver, and the power end of described optical transceiver is connected with failure indicating circuit.
Described failure indicating circuit comprises drive circuit and indicating circuit, and the input of drive circuit is connected with the power supply of optical transceiver, and the output of drive circuit is connected with the input of indicating circuit.
Described drive circuit comprises variable resistor, diode, triode, and variable-resistance first end is connected with the power supply of optical transceiver, and second end is connected with the base stage of triode by first resistance, and variable-resistance adjustable side is connected with variable-resistance second end; The positive pole of diode is connected with the power supply of optical transceiver, and the negative pole of diode is connected with the emitter of triode, and the collector electrode of triode connects indicating circuit.
Described indicating circuit comprises buzzer and electric capacity, and the positive pole of buzzer is connected with the collector electrode of triode, the minus earth of buzzer, and the positive pole of electric capacity is connected with the negative pole of diode, the minus earth of electric capacity.
The utility model is connected with accident indicator at the power end of optical transceiver, and when optical transceiver generation power failure, accident indicator just can be reminded the person on duty, and the person on duty reports rapidly, and the communication personnel are in time handled, and makes transformer station's normally operation as early as possible.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
As shown in Figure 1, a kind of faulty indication optical transceiver of the utility model, comprise optical transceiver, the power end of described optical transceiver is connected with failure indicating circuit, described failure indicating circuit comprises drive circuit and indicating circuit, described drive circuit comprises variable resistor VR1, diode D1, triode T1, first end of variable resistor VR1 is connected with the power supply (5V is to 15V) of optical transceiver, second end is connected with the base stage of triode T1 by first resistance R 1, and the base stage of triode T1 also connects second resistance R, 2 back ground connection; The adjustable side of variable resistor VR1 is connected with second end of variable resistor VR1; The positive pole of diode D1 is connected with the power supply of optical transceiver, and the negative pole of diode D1 is connected with the emitter of triode T1, and the collector electrode of triode T1 connects indicating circuit.Described indicating circuit comprises buzzer B1 and capacitor C 1, and the positive pole of buzzer B1 is connected with the collector electrode of triode T1, the minus earth of buzzer B1, and the positive pole of capacitor C 1 is connected with the negative pole of diode D1, the minus earth of capacitor C 1.
As shown in Figure 1, the utility model has capacitor C 1(to adopt the electric capacity that capacity is bigger) the required warning power supply of buzzer B1 when the optical transceiver power failure is provided.When the optical transceiver supply voltage just often, triode T1 ends, buzzer B1 does not work, power supply by diode D1 to capacitor C 1 charging; When the optical transceiver power supply breaks down, voltage descends or when disappearing, triode T1 conducting, diode D1 ends, this moment capacitor C 1 by buzzer B1 discharge, send chimes of doom, prompting operator on duty optical transceiver power supply breaks down.
