The design and operation of substation remote viewing system

Abstract: the design and operation of substation remote viewing system information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. The introduction remote image monitoring system of heshan power bureau substation ( This system) Began in July 2001, installation and commissioning, starting with three station, station capacity in October 2001 to 10, has formed a substation remote video surveillance network. This system is a set of. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the design of substation remote viewing system and run the article details. The introduction remote image monitoring system of heshan power bureau substation ( This system) Began in July 2001, installation and commissioning, starting with three station, station capacity in October 2001 to 10, has formed a substation remote video surveillance network. This system is a set of based on TCP/IP network, with the standard image, voice and IP packet control data of new monitoring system, its core technology is IP multicast technology, as a result, network design, installation and operation maintenance and the previous image. Monitoring and control system is put in bigger difference. 1 this system according to the equipment and control system design of where the software, can be divided into image acquisition and field monitoring, network transmission, the monitoring center monitoring maintenance three parts. Among them, the image acquisition part of the same design with the traditional monitoring system, this system key is the design of the IP network. Each station configuration l ~ 4 sets of 8 x16 high-speed ball and 1 ~ 2 times the Pelco integration 16 times take yuntai color video camera, with three variable lens. Integration of high-speed ball is installed on the roof, it is mainly used for monitoring main transformer and do big range scan, in the place such as the master control room, high and low voltage room, communication room to install the camera. In the place where is wide for scope requirements configuration a fixed camera gun and wide Angle lens. In substation infrared probe configuration around the doors and walls. 2 on-site monitoring control matrix matrix basic configuration is 32 road 8 road input, output, but has good expansibility, can be expanded to 64 road, fully meet the needs of the substation. So, if need to add a camera in the future, can be easily added to the system. Also has alarm monitoring matrix interface, is the infrared sensor alarm output from the early monitoring matrix, the matrix is transmitted to the monitoring center by monitoring, the monitoring center of alarm processing, can by way of voice alarm events for the response. 3 video frontend video - front machine USES standards 48 v communication power supply, thus it can be use the standby power of communication room, in the case of a 220 v power supply is not normal, can ensure the normal operation of the video frontend. Front machine USES hardware compression of video signal compression and transmission after packaging, at the same time, accept the orders of the monitoring center, to image the matrix switch control, alarm information collected, and through the matrix of intelligent high-speed ball, yuntai, camera, lighting, etc. 1．410Base- T / G。 703 converter this system to connect the monitoring center as the center consists of a star network topology structure, basic network channel is a standard Ethernet, transmission channel is E1. On the station side, the Belgian Indus company l0Base - T / G。 703 of the converter, the Ethernet packets automatic conversion on E1 transmission; And in the end, then back again, become the standard of Ethernet packets. Indus the converter working at layer 2, as a transparent bridge, therefore, stand the client and the monitoring center are in the same local area network (LAN). The converter also support routing, however, for the sake of the network is simple and reliable, easy to maintain, or make it work in a transparent bridge model. 5 monitoring center monitoring center computer is used to communicate with the host and processing the video signal. The design, in the central control room using l0Base - T / G。 703 converter will optical transceiver signal coming directly to the monitoring center in the network. Considering the independence and stability of the electrically controlled system, the monitoring center of local area network should be independent of the network, and through a fibre channel and heshan power bureau MIS network connection. In order to continue to ensure the independence and stability of the monitoring network, don't let video streaming influence MIS network at the same time, must delimit monitoring network in separate vlans. Due to deal with a lot of video streams and request support IP multicast, chose CiscoCatalyst3524 monitoring center of the switches. Heshan power authority center switches is CiscoCatalyst6509, high performance, support IP multicast. The following calculation performance requirements of switches and routers. According to the standard VCD, video stream is 1150 kbit/s, which is 144 KB/s, a video UDP is about 1. OkB ~ 1。 5 KB, therefore, each video UDP packets per second need zui number is 150. So, 10 road video packet forwarding ability demand for switches is 1500 per second.

is emerging as one of the most popular mass flow meter, moving beyond its digital fork density meter benefits, with conclusive scientific evidence suggesting the positive role play in rosemount coriolis mass flow meter.
