The Design For Construction Project Evaluation Monitoring System

With the development of society, the requirements of supervision and management have been continuously enhanced in intelligence and automation. The video surveillance system is one of the important methods of management, monitoring and control, and greatly improves the management efficiency and the level of automation, which has been widely used in industry, commerce, finance, transportation, public security, military, the residential quarters and other fields. In order to make the evaluation process of engineering more fair, just and open in the construction activity, the supervision is more important. Therefore, the use of advanced means is very important in the evaluation process of supervision and monitoring.The video monitoring system is an advanced method in the evaluation process. In this system, cameras and monitor devices are employed to pick up the signal of the front-end video and audio; Switch with audio and video, controllers, video tape recorder, etc as intermediate processing control equipments; The matrix switch with audio and video is the tool of signal distribution switching; Controllers are the interface of systematic dialogue; video tape recorder plays a unique role in the VCR control of the front-end equipment and records of information; the Multi-screen with the right combinations is employed to achieve one or more evaluation room video to display. The system performs a signal of the reception, transmission, processing, displaying and recording.This paper introduces the choice of equipment of the technical parameters and norms with the combination of system design in scene situation and the actual request for details, which makes the application of monitoring system to be practical.Finally, the subsystems of evaluation supervision and management system, such as expert database, expert evaluation management, expert selection and notice, fingerprint validation, computer evaluation, evaluation process supervision and answering questions talk-back are deeply investigated ,analyzed, designed and developed.
