Abstract
Systems and methods improve the actionability of leaks in cable networks. One or more leakage detection confidences (LDCs) are determined to assess the reliability of newer leakage data which conflicts with existing leak records. When confidences fail to exceed predetermined thresholds, records of leaks which failed to be redetected are maintained as actionable and relied upon for the creation of work orders and deployment of technicians to make repairs. Further fail safe conditions may include device health metrics and weather events.
Claims20
A method of maintaining cable infrastructure involving a leak which was detected on an earlier driveout and which was not redetected on a later driveout, the method comprising
- determining for the later driveout a first leakage detection confidence (LDC) as a ratio of (i) number of leaks detected to (ii) number of leaks expected;
- comparing the first LDC with a first threshold;
- and
- deploying a technician to repair the leak if one or more fail safe conditions are met, the one or more fail safe conditions comprising:
- the first LDC fails to exceed the first threshold.
A method of maintaining cable infrastructure, comprising
- (a) for each leakage record of one or more existing leak records, identifying those for which there was no redetection on a later driveout but a plurality of fail-safe conditions are satisfied, the plurality of fail-safe conditions comprising
- a driveout leakage detection confidence (dLDC) fails to exceed a first threshold, and
- one or more of (i) a detector which collected leakage data on the later driveout receives a fail rating for device health, and (ii) a node leakage detection confidence (nLDC) for a node associated with the driveout record fails to exceed a second threshold;
- and
- (b) deploying a technician to repair a leak indicated by a leakage record identified in step (a),
- wherein the dLDC is a ratio of (i) number of leaks detected on the later driveout to (ii) number of leaks expected on the later driveout, and
- wherein the nLDC is a ratio of (i) number of leaks detected on the later driveout which are within a node on a driveout path and (ii) number of leaks within the same node expected on the later driveout.
A non-transitory computer readable medium comprising computer-readable instructions which, when executed by one or more computers, cause the one or more computers to perform a method of maintaining cable infrastructure, the method comprising
- for a leak which was detected on an earlier driveout and which was not redetected on a later driveout, determining for the later driveout a first leakage detection confidence (LDC) as a ratio of (i) number of leaks detected to (ii) number of leaks expected;
- comparing the first LDC with a first threshold;
- and
- maintaining or changing a record of the leak to actionable status for deployment of a technician to repair the leak if one or more fail safe conditions are met, the one or more fail safe conditions comprising:
- the first LDC fails to exceed the first threshold.
