  • IN-SITU FLOW DETECTION METHOD AND APPARATUS
    Publication number: 20230006906
    Abstract: An in-situ flow detection method. When determining a transmission delay in a detection domain in a first in-situ flow detection period, a first network node may color a plurality of packets in a first service flow that are received by the first network node through a first inbound interface and determine the delay in the detection domain in the first in-situ flow detection period based on the plurality of colored packets, thereby improving the precision of the detected transmission delay in the detection domain.

  • Method and system for monitoring power transmission line of power grid
    Patent number: 9158036
    Abstract: A system for monitoring a power transmission line of a power grid, including a first comprehensive sensor (402, 502) disposed at the intermediate position of a power transmission line between two towers including an altimeter, a first acceleration sensor, a temperature and humidity sensor and a rainfall sensor; a second comprehensive sensor (404, 504) disposed at the cable connector of the power transmission line including a leakage current sensor, a tension sensor and a wind speed and direction sensor; and a second acceleration sensor (406, 506) disposed at the intermediate position of the power transmission line between the cable connector of the power transmission line and the first comprehensive sensor (402, 502). A method for monitoring a power transmission line of a power grid, including a step of monitoring the sag condition, wind yaw angle, motion and position tracking, flutter conditions, breeze vibration level, fatigue life and icing situation of a power transmission line.
