Abstract
The invention relates to a method for automatically regulating optical power. The method comprises steps as follows: after a dynamic power control function is started, a head node duly transmits an output optical power value as an output optical power value expected by downstream nodes to the downstream nodes through a 2.112M data channel, element management U-disks (EMU) of the downstream nodes monitor a difference between the output optical power of the current node and the expected output optical power through acquiring an output power value of an amplification disk; and when the head node increases or reduces the quantity of carriers or line attenuation is increased to cause that the difference changes and exceeds a regulating threshold, the EMUs automatically send a regulating command to the amplification disk for regulating the power output value. According to the invention, the EMUs are cooperated with a web master, an optical supervisory channel (OSC) and the amplification disk to be capable of automatically carrying out power transmission and processing and completing an automatic optical power regulation function, and the purpose of dynamically regulating the output optical power of each node to an ideal output value is achieved without manual control and regulation.

21, non-first node is after receiving full link adjustment order, with the integral power deviate that remedies Line Attenuation and upstream node transmission and get off, no matter and whether both sums cross the Line Attenuation detection threshold value; The Output optical power of each node is more near desirable Output optical power, i.e. the Output optical power desired value;
Step 2101, non-first node are received full link adjustment order, go to step 2102;
Step 2102, check that whether the amplification dish that belongs to this link exists that input light is lost alarm, the amplification dish is not in place and the alarm of eye protection, if no alarm goes to step 2103, otherwise goes to step 2108;
Step 2103, carry out the full link adjusting operation in this node, go to step 2104;
Step 2104, judge whether end-node of this node, if end-node goes to step 2105, otherwise go to step 2109;
If whether step 2105 accumulative total luminous power deviate totalWaveOffset within the normal range (NR) of regulation, shows and this time adjusts successfully, go to step 2106, otherwise go to step 2110;
Step 2106, end-node go to step 2107 to first node report adjustment success;
Step 2107, end-node detect whether receive the acknowledgement frame of first node within 10s, if do not receive acknowledgement frame, go to step 2113;
Step 2108, this node directly report to first node and this time adjust unsuccessfully, stop simultaneously transmitting to downstream node adjusting and order;
Step 2109, transmit full link adjustment order to downstream node;
If whether totalWaveOffset is less than the redundant EVOA value of accumulative total for step 2110 accumulative total luminous power deviate, goes to step 2111, otherwise go to step 2114;
If step 2111 does not respond and this time adjusts end-node and applied for again full link adjustment, go to step 2112, otherwise go to step 2115;
Step 2112, this node report the wave spectrum adjustment to cross the border to first node, go to step 2107
Step 2113, every 5s resend to first node and once adjust the result, send altogether 6 times;
Step 2114, this node report the wave spectrum adjustment to cross the border to first node, go to step 2107;
Step 2115, this node apply for again that to first node full link has adjustment.
6. the method for automatic adjustment luminous power as claimed in claim 3 is characterized in that, described communication link communication conditions detects associative operation and may further comprise the steps:
Step 301, judge whether first node opens DPA, if open DPA, go to step 302, otherwise go to step 306;
Step 302, judge whether to receive single node adjustment order, if received single node adjustment order, go to step 303, otherwise go to step 301;
Step 303, judge whether received single node adjustment order within 5 minutes, if receive single node adjustment order, go to step 304, otherwise go to step 307;
Step 304, judge whether each amplification dish has alarm in this node, if alarm is arranged, goes to step 305, otherwise goes to step 308;
If step 305 has wave spectrum to adjust the communication disruption alarm, then cancel this alarm;
If step 306 has wave spectrum to adjust the communication disruption alarm, then cancel this alarm;
Step 307, produce and report wave spectrum to adjust the communication disruption alarm to webmaster, go to step 301;
Step 308, judge that whether each amplification dish of upstream node has alarm, if alarm is arranged, goes to step 305, otherwise goes to step 309;
Step 309, fill order's node detect adjusts associative operation.
7. the method for automatic adjustment luminous power as claimed in claim 3 is characterized in that, described amplification dish may further comprise the steps with the associative operation of communicating by letter that the EMU dish carries out data interaction:
The warning information that step 401, reception amplification dish report goes to step 402;
If step 402 amplification dish has alarm, go to step 403, otherwise go to step 408;
If this node of step 403 is first node, goes to step 407, otherwise go to step 404;
Step 404, to the warning information of first this node of node report, and this node is set to the alarm attitude, go to step 405;
If receive the acknowledgement frame of first node in step 405 30s, go to step 406, otherwise go to step 404;
Step 406, first node add the warning information of this node in the alarm chained list;
Step 407, first node add the warning information of this node in the alarm chained list, and this node is set to the alarm attitude;
If step 408 should the amplification dish alarm arranged in last time during poll, go to step 409;
If equal no alarm is coiled in all amplifications on this link of step 409, go to step 410;
If node headed by this node of step 410 goes to step 411, otherwise go to step 412;
Step 411, from the alarm chained list switching information of this node of deletion, and this node is set to preparing state;
Step 412, disappear to first this node of node report alarm, and this node is set to preparing state; Go to step 413;
If receive the acknowledgement frame of first node in step 413 30s, go to step 414, otherwise go to step 412;
Step 414, first node are deleted the switching information of this node from the alarm chained list.
