User profile: Hangzhou power grid transmission line state monitoring center is enabled formally November 30, 2010, set office, monitoring, emergency command in one, with safety precaution, assistant decision-making, visualization management function command center.

Project Overview: through the LCD display, can be achieved on the conductor temperature, icing conductor, conductor windage yaw, conductor sag, Micro Weather video image parameters acquisition, processing, storage, display and application, and with PMS ( transmission and distribution of integrated production management system ), GIS ( Geographic Information System ) platform integration, system integration of the dynamic monitoring information and static grid information, to a greater extent to master the running state of the equipment.

Solution: the display system is composed of 18 NEC ultra narrow side liquid crystal X462UN 3 * 6 form constitutively spliced, each collecting site and GIS video signal by an image processor is transmitted to the spliced large screen, so as to realize real time monitoring, while the internal LAN computer access image mosaic controller. Big screen can be realized simultaneously display the video signal and computer signal, and the superimposed images, such as roaming function.

Project acceptance criteria:

( 1) in combined screen unit is fixed by a reliable mechanical way, not loose, the phenomenon of displacement.

( 2) a vertical screen: overall vertical requires less than 10mm.

( 3) the screen level requirements: overall level requires less than 10mm.

( 4) the screen horizontal spliced between requirements: patchwork uniform, gap within 0.5mm. Hand touch with no apparent seizure.

( 5) the screen between before and after sewing requirements: patchwork uniform, time difference of less than 0.5mm. Hand touch with no apparent seizure.

( 6) four screen splicing intermediate cross stitch: cross seams should be no obvious malposition.
