It is still beneficial to the expansion of the application and monitoring system itself in the future.
The transmission equipment of the original monitoring point is very stable, and the digital transformation based on the network also requires a large amount of investment. Therefore, it is not advisable to completely build a new network-based monitoring system. The integration of the network-based monitoring system and the analog monitoring system is based on the full use of existing resources, saving investment, and taking into account the development direction of the video surveillance system, which is the starting point of the expansion plan. In this regard, we have retained all of the original simulation systems. The design of the network part takes into account the importance of Baosteel's backbone network for production. In order to avoid the impact of multicast traffic on individual network nodes, three multicast core points (router 1, 2) are newly set according to the geographical distribution. 3), the monitoring point is connected to the core point routing switch by the Cisco Layer 2 switch. The network device at the core point uses Cisco's Layer 3 switch to enable OSPF routing, which belongs to the same area as the original backbone network. Due to the one-to-one correspondence between the codec and the decoder, that is, the receiving user in the multicast group has only one decoder, the transmission efficiency of the video IP data packet in the network is not higher than that of the unicast, and the scheme cannot be embodied in this scheme. The advantages of multicasting, but for the future expansion of the application and monitoring system itself is still beneficial. After the implementation of the expansion, the original keyboard can control the newly added camera and the pan/tilt, maintaining the integrity of the entire system. Due to the adoption of MPEG-2 encoding, the image quality of the newly added monitoring points is higher than the original monitoring point, and the digital transmission plays a role in improving the image quality. However, when the keyboard control is switched to the newly added monitoring point, the screen switching has a delay of 12s, and the original analog monitoring point has no obvious feeling.
