Drawings

Fig. 1 is a circuit diagram of an embodiment of an alarm circuit for an ONU device.

Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, it is a schematic diagram of an embodiment of an alarm circuit for an ONU device according to the present invention, the alarm circuit includes a PON indicator lamp 1, a sound generating module 2, a resistor 3, and a signal detection unit 4.

The PON indicator light 1 is preferably a light emitting diode, and is configured to emit light when the PON indicator light 1 is turned on in a line; the sound production module 2 is preferably a buzzer and is used for producing sound as an alarm reminding signal. The signal detection unit 4 is preferably an optical signal detection unit, detects whether the ONU device is in an optical burst state by the signal detection unit 4, and outputs a high level when the ONU device is in the optical burst state; when the ONU device is in the normal registration state, the signal detection unit 4 outputs a low level.

The positive pole of the PON indicating lamp 1 is electrically connected with the resistor 2, and the other end of the resistor 2 is electrically connected with the voltage U. The positive electrode VCC is electrically connected with one end of the resistor 2 connected with the voltage U, and further electrically connected with the voltage U and indirectly electrically connected with the positive electrode of the PON indicating lamp 1. The cathode of the PON indicating lamp 1 is electrically connected with the I/O end of the sounding module 2 and the signal detection unit 4.

In implementation, the ground GND of the sound module 2 is electrically connected to the ground of the PON indicator light 1. The voltage U is +3.3V, and the high level output by the signal detection unit 4 is at the same potential as the voltage U.

When the optical network unit is used, when the ONU device is in a normal registration state, the signal detection unit 4 outputs a low level, that is, the negative electrode of the PON indicator light 1 is at a low level, the PON indicator light 1 is in a conduction state, the PON indicator light 1 is on, the sound generation module 2 is not triggered, and no sound is generated. When the ONU equipment is in the optical burst state, the signal detection unit 4 outputs a high level, namely, the negative pole of the PON indicating lamp 1 is at the high level, the PON indicating lamp 1 is in a non-conducting state, the PON indicating lamp 1 is not on, the sound production module 2 is triggered, and sound is produced to serve as alarm reminding.

The accompanying device comprises an alarm circuit shown in fig. 1, and is arranged in the optical link when in implementation. When ONU equipment is in normal registration state, can not cause the influence to accompanying and surveying the device, signal detection unit 4 output low level, PON pilot lamp 1 negative pole is low level promptly, and PON pilot lamp 1 is in the on-state, and PON pilot lamp 1 is bright, and sound production module 2 is not triggered, does not make sound. When ONU equipment is in the light burst state, make and accompany and survey the unable normal registration of device, signal detection unit 4 detects that export high level after light signal intensity weakens, and PON pilot lamp 1 negative pole is high level promptly, and PON pilot lamp 1 is in the non-conducting state, and PON pilot lamp 1 is not bright, and sound production module 2 is triggered, sends sound as warning and reminds.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
