Influenced by the residual circulation of
typhoon "sea anemone", monsoon and weak cold air, a super historical
extremely heavy rainstorm occurred in Shenzhen from the evening of September 7
to the morning of September 8, with the characteristics of "super strong
intensity, super long duration and super wide range of heavy rainfall". As
of 14:00 on the 8th, the rainfall in Shenzhen has broken seven historical
extremes since the meteorological records began in 1952. Many areas have been
severely affected, and some areas have experienced power outages. Electricity
plays a crucial role in people's work and life, so the power department
immediately carried out power supply repair. Next, let's learn how RFID can
play its role in power repair.
Quickly locate faulty cables
Nowadays, many cables have been equipped
with buried RFID tags for information management. Buried tags are used for
digital electronic identification of cable channels, achieving precise
positioning, searching, identification of underground facilities, and judgment
of cable routing. Usually buried underground along with the cable (due to the
harsh environment, low-frequency RFID tags with good anti-interference are
used). In practical operation, a buried label is usually installed near the
manhole cover, and then the next one is installed every 50 meters. This type of
label has a high level of protection (can meet the requirements of reliable
recognition in water, plastic, soil, cement, asphalt and other media
environments), and has the characteristics of waterproof, dustproof,
anti-corrosion, and long service life.
When conducting cable fault repair in power
supply companies, through the RFID based cable lean platform, staff can quickly
identify suspected fault points based on the fault cable section analysis
information, thereby shortening the cable fault repair time and improving
repair efficiency.
Efficient positioning of faulty power poles
In the past two years, leading companies in
the industry have developed ultra-high frequency RFID reader products
specifically designed for RFID drone inspection services of power distribution
towers. These products have the advantages of small size, light weight, and
long recognition distance (by cooperating with specialized RFID bidirectional
electronic tags, the recognition distance can reach 18 meters). By combining
RFID and drones, the location of faulty poles and towers can be quickly and
accurately located (some drones can also take photos of faulty poles and send
them back to the backend), greatly improving the intelligence level and
emergency repair efficiency of power repair.
Improve the management level of
construction equipment on power emergency repair sites
At the power repair site, when the repair
task is relatively complex and the repair time is relatively long, sometimes
there may be situations where power tools and instruments are lost. Later, the
power department introduced RFID for intelligent management to help develop a
highly localized and highly aware full process digital management solution. In
addition, using RFID technology, the power grid company has achieved cross
departmental business collaboration and strengthened its ability to control the
entire infrastructure process.
