Pumping station control automation

Pumping station automation system includes computer monitoring system, LCU monitoring system, video surveillance system, power integrated protection system and so on. The network structure of the monitoring system adopts the optical fiber Ethernet, the monitoring host computer, the communication computer and the LCU are all hung on the ethernet.

1. computer monitoring system
The computer monitoring system set up two sets of monitoring host computer, including the function of operation control and management of the whole LCU pumping station monitoring system, data processing and database management, online and offline calculation function of the charts and curves of production accidents, fault signal analysis and processing. Two monitoring hosts form redundant hot standby. When a monitoring host fails, another monitoring host can continue to work.

2. local control unit LCU
LCU mainly complete data acquisition and data preprocessing, but also has the function of control and monitoring. LCU has the function of communicating with the main control level, transmits the process information needed to the main control level at regular time, and accepts the control command from the main control level to realize the real-time control of the field equipment.

3. video surveillance system
Video surveillance system consists of four parts: front-end equipment, transmission equipment, control equipment, and display. The front-end equipment is composed of integrated spherical color cameras mounted on and around the station and fixed high resolution color camera, responsible for the acquisition and processing of image and data transmission equipment; can choose different kinds of cables, transmission distance and interface equipment according to the requirements of image quality; integrated video host is responsible for receiving a video signal, the video signal (Analog) is converted into a digital signal, the hard disk video and displayed at the same time, through the Ethernet LAN connection, the image signal can be transmitted to the desired location, control, PTZ and lens is responsible for the completion of the front-end equipment and switching the image.

4. integrated power protection system
This project is equipped with electrical integrated protection system, comprehensive protection system is composed of comprehensive protection device, communication management machine and monitoring operation background machine. Monitoring and control of electric equipment can be realized on the monitor operation backstage machine.
