The invention discloses a
power transmission line
polling system. The
system comprises a
personal computer (PC) side control terminal, a
server and a handheld personal digital assistant (PDA), wherein the PC side control terminal, namely a PC side
management system, performs
polling task management,
polling condition management, defect management, defect standard management and
geographic information system (GIS) geographic
information management; the
server receives and transmits information and stores data in real time, comprises an enterprise
database and a Socket detectaphone which is used for detecting
wireless data in real time, and is called a
server Socket data receiving and transmitting
system for short; and the handheld PDA performs field polling, is a mobile terminal which feeds back polling information through
general packet radio service (GPRS), and is called a PDA mobile terminal
polling system for short. The advanced technologies of a
global positioning system (GPS) and a palm computer are fused in the system, and
power transmission line polling is realized by using a component GIS technology and introducing the concept of embedded GIS; the system performs relatively precise positioning and complete defect
data acquisition, can be used for a line polling step in a power system which is used for
power transmission, power distribution and the like, and also can be widely applied to the management of the outdoor entities of telecommunication,
coal gas,
natural gas and the like which are related to the polling; and the
operating cost is effectively lowered, and the economic benefit is effectively improved.
