I, What are the demands of the online monitoring system of the primary equipment on the communication equipment? How does the AOBO industrial Ethernet switch satisfy these demands?
1. Since the online monitoring equipment is placed under the environment with high voltage and strong electromagnetic interference, the internal communication equipment should have the capability of withstanding the strong electromagnetic interference;
AOBO series of industrial Ethernet switches have the superior electric circuit and process design, reach the EMC level 4 standards and provide the resistance to the strong electromagnetic interference and surge protection.
2. Since the online monitoring equipment is placed under the state of non-air conditioning protection, the internal communication equipment should be capable of operating normally for a long time under the adverse environment;
AOBO series of industrial Ethernet switches are featured by low power consumption and fanless design and suitable for the long term and stable operation under the non-air conditioned working environment temperature of -40℃~+85℃.
3. The communication isolation between the online detection system and other systems of the substation (such as the state grid system) and information security should be guaranteed while ensuring the smooth communication inside the online detection system.
AOBO series of industrial Ethernet switches provide several technologies, such as the port speed limitation, broadcast storm control, port isolation, VLAN and multicast limitation and ensure the communication isolation between the online detection system and other systems of the substation (such as the state grid system) and information security while guaranteeing the smooth communication inside the online detection system.
4. The equipment should support the long-distance transmission communication, because the distance of all nodes in the online detection system is relatively large;
AOBO series of industrial Ethernet switches are fitted with the fiber interfaces and the users may, based on the actual demands, select the corresponding equipment model and configure the quantity of the optical interfaces to meet the demands about the long-distance transmission.
5. As the critical equipment of the online monitoring system, the communication equipment should keep maintenance-free, realize the long-term, uninterrupted and stable operation and avoid the whole network paralysis caused by the single-point failure on the network;
AOBO series of industrial Ethernet switches have been proved to possess the reliability of the long-term and uninterrupted operation in the large quantities of the mature commercial applications under the same type of the application environment;
At the same time, AOBO series of industrial Ethernet switches are also in possession of the distinct product features, such as the ABRing full-distributed high self-healing loop network technology with the self-healing time less than 5ms, ABPass outage light path protective technology and broadcast storm “source isolation” technology. The whole network paralysis caused by the single-point failure could be avoided effectively.
6. The communication equipment must conform to the technological development trend of the online monitoring technology and intelligent power grid, support the power grid standards (such as IEC 61850) and remain compatible with the future business development (such as the video);
AOBO series of switch products adopt the industrial Ethernet technology, conform to the development trend of the intelligent power grid technology and support the IEC61850 standards.
AOBO series of industrial Ethernet switches provide the standard Ethernet broadband interface and realize the non-blocking transmission at the line speed for laying a foundation for the future business expansion of the online monitoring system.
7. During the equipment installation, realize the plug and play as much as possible and abandon the tedious configuration.
During the installation process, AOBO series of industrial Ethernet switches should guarantee the plug and play and abandon the tedious configuration.
8. It is necessary to monitor the equipment remotely and check its operating status for the engineering inspection;
AOBO series of industrial Ethernet switches (except for AOBO 3 series) support the remote management and monitoring by operating the ABNet software and are capable of paging all equipment conveniently via the ABNet management software, inspect the equipment attributes and connecting status of the port, check to see whether the loop network is enabled, examine the port of the opposite end equipment connected to this equipment and network topology formed by the whole link so as to enable the users to implement the equipment management and maintenance easily.
