The Design And Realization Of Engineering Construction Field Remote Video Monitoring System

In recent years, with the rapid development of computer application technology, the radio communications and mobile communications technology, the electronic video monitoring system has been widely used. With the rapid growth of national economy and social progress, the demand for safety guarding and scene recording alarm system in bank, traffic, security and campus has be grown with each passing day, at the same time, the requirement is becoming higher and higher. Video surveillance had a widely used in all aspects of production and life. Putting the electronic video monitoring into the construction project of the construction site, construction quality, safety and civilized construction and environmental protection and daily production scheduling meetings and construction management, the purpose for this is completing the construction supervision of the construction site.Thispaper analyzed and studied the key technologies of remote video monitoring. According to the actual situation of Minhou County, Fuzhou City Commission for discipline Inspection Office building construction project site, a set of remote video monitoring system of engineering site was designed and implemented. System implements a project of reading videos, remote monitoring, remote control, remote system administration and multi-screen video Windows,1 to 15 road wheels tour features such as display.The remote video monitoring system of engineering construction field mainly comprises three parts, including:the front monitoring point, monitoring network and monitoring center, The system through VFW technology promptly gathering and the processing monitoring video frequency, uses the MPEG-4 video frequency compression module compression video frequency, carries on playbacking using the DirectShow technology to the preserved video recording.At the same time, making a playback of the saved video using DirectShow. After acquisition and processing, based on the method of combining the TCP, UDP, IP multicast and RTP in transmission, transmitting the monitoring and control information with Winsock control and IP multicast. According to principle of holder control system. The control function was realized using the Windows serial port technology. By monitoring platform that had been built, the front video image could be rotated and managed.
