The invention discloses an online
monitoring system for a high-tension
transmission line based on a
wireless sensor network. The online
monitoring system comprises a conductor
temperature monitoring terminal, a meteorological environment monitoring terminal, a circuit data collection terminal, a
conductor sag monitoring terminal, the
wireless sensor network, a circuit monitoring
base station, a
database terminal, a background monitoring center
station and an alarm terminal module, wherein the circuit data collection terminal is used for collecting
data information of the conductor
temperature monitoring terminal, the meteorological environment monitoring terminal and the
conductor sag monitoring terminal, transmitting the
data information to the circuit monitoring
base station through the
wireless sensor network based on a Zigbee protocol, and transmitting the
data information to the background monitoring center
station through a GPRS (
general packet radio service) network; the background monitoring center
station is used for storing the received circuit information into the
database terminal, and timely sending out alarm information through the alarm terminal module when the data information is abnormal. According to the online
monitoring system, real-time omnibearing monitoring of related parameters such as conductor temperature,
conductor sag and meteorological environment can be achieved; and the online monitoring
system can be widely applied to monitoring of the high-tension
transmission line of an
electric power system.
