The main control center of the central control room uses hard disk video recorder control equipment to centrally control the entire reservoir monitoring system. At the same time, the center is equipped with a monitoring system to centrally monitor the front-end monitoring system. Through the transmission of front-end equipment signals, automatic monitoring functions are realized No personnel control is required, and the operation is convenient. Agriculture and technology. The composition of the system This monitoring system is a set of highly practical and high-tech TV monitoring system. It mainly includes: front-end system, transmission system and terminal system.
The camera adopts the American high-line-count low-illumination color camera, which has internal synchronization and power synchronization functions. The model is GC-755PX-A2-G. The electronic shutter can adjust the white balance and frame phase, and has automatic gain control, backlight compensation and other functions. , Good color, high resolution, low illuminance, has a high cost performance.
The focal length of the lens is twice that of 3.0mm ～ 8mm. The zoom lens can be continuously adjusted within the range of 91 ° ～ 67 °. Aspheric lens is used to obtain high definition, high contrast, small size, and ultra-wide dynamic range F / 1.0 ～ F / 360, can be adjusted to the best monitoring angle according to the actual situation of each monitoring point.
Transmission system The monitoring and transmission system of the reservoir area is responsible for transmitting the image signal taken by the front-end equipment to the terminal equipment of the control center through a professional cable. An embedded 8-channel hard disk recorder is used. In this solution, the most advanced embedded hard disk recorder is used. In the actual operation and monitoring process, the staff needs to monitor one of the images, and can freely switch, record and other functions.
