As shown in Figure 2, use the method that the utility model improves the alarm accuracy rate, comprise following steps:
Step 1 presets loss alarming threshold value, each joint and the acceptable loss threshold value thereof of each optical cable to be measured, continuous alarm frequency threshold value in operation control terminal 8.This step specifically comprises:
Step 1.1 according to specification, the behaviour in service of each optical cable to be measured, presets the loss alarming threshold value of every optical cable to be measured.
Step 1.2 according to the actual joint situation of each optical cable, presets each joint and the acceptable loss threshold value of each joint of every optical cable to be measured.
Step 1.3, what recur alarm according to the how many times of relevant staff's accumulation may be the working experience of true alarm, presets continuous alarm frequency threshold value.
Step 2 is set test period, and optical time domain reflectometer 9 carries out loss test to each fiber cores of each optical cable 4 to be measured of monitoring successively.This step specifically comprises:
Step 2.1 is set test period, and within the cycle of setting, optical time domain reflectometer 9 carries out loss test to each fiber cores in each optical cable 4 to be measured of monitoring successively.
Step 2.2 is judged and whether the test of each optical cable 4 to be measured is finished in the current period, if the traversal test of each optical cable 4 to be measured is finished then enter wait state, until next test period begins.
Step 3, operation control terminal 8 reads in real time optical time domain reflectometer 9 and tests the lossy data of every fiber cores of the every optical cable 4 to be measured that obtains.
Step 4, operation control terminal 8 judges whether lossy data exceeds alarming threshold, the lossy data of every fiber cores of every optical cable 4 to be measured reading and the loss alarming threshold value that step 1 is set are compared, if lossy data is greater than loss alarming threshold value then think alarm event may occur, proceed step 5, continue next root optical fiber cables fibre core to be measured is carried out loss test otherwise return step 2.
Step 5, operation control terminal 8 judges whether alarm event is in the joint and whether lossy data meets the acceptable loss threshold range of joint, if alarm event is in joint and lossy data less than the acceptable loss threshold value of this joint, then return step 2 and continue next root optical fiber cables fibre core to be measured is carried out loss test, otherwise carry out step 6.This step specifically comprises:
Step 5.1 judges that whether alarm event is in the predefined joint of step 1, proceeds step 5.2 if alarm event is in the joint.
Step 5.2, the acceptable loss threshold value of corresponding joint that the lossy data that reads and step 1 are set compares, if lossy data greater than the acceptable loss threshold value of joint then proceed step 6, continues next root optical fiber cables fibre core to be measured is carried out loss test otherwise return step 2.
Step 6, the continuous alarm of same fiber cores of 8 pairs of same optical cables to be measured of operation control terminal is counted, and the continuous alarm frequency threshold value that this enumeration data and step 1 are set compares, if enumeration data is greater than continuous alarm frequency threshold value then think that real alarm event carry out step 7, otherwise think that the mistake alarm returns the lossy data that step 3 continues to read the optical time domain reflectometer test.
Step 7,8 pairs of step 8 enumeration datas of operation control terminal are carried out record greater than the event of continuous alarm frequency threshold value, and outwards alarm.This step specifically comprises:
