| Network video monitoring system combines with the major advantagesfrom Internet and embedded technology, breaking the traditional videomonitoring system,not only which can transmit images and text, but also videoand audio at the same time. In various industries, the unit has been widelyapplied by realizing multimedia features. The camera controlled by PTZ is nowanother mainstream. as technology continues to progress, video monitoring willbe in high-definition, intelligent, professional direction.The design and research about network video monitoring system andcontrol system based on the gec2410can not only meet the remote imagetransmission, and expanded the range of camera surveillance.This author introduced the gec2410development board hardwarestructure, expounded the working principle of network video monitoring system,design and other content. Achieved Linux operating system establishment andsystem file transfer based on the virtual machine in the development board,network adapter, USB camera driver loading, the boa server transplant.Designed the PTZ control module, described its working principle, and usedassembly language to achieve the control of stepper motor about direction.We finally can get the collected image through the experiment. as thecamera 's own reasons, resolution is low. By adjusting the pulse interval and themotor driving mode, combined with the performance indexes of the standard,wecan make the head of the stepper motor work stably, speed and accuracy can beeffectively identified. |
