ICT technology has been continuously improving the overall strength of the power industry, and now it has entered the era of smart grids. However, due to the wide distribution of power equipment and the large area involved, it is becoming more and more difficult to invest in the maintenance and repair of power equipment. How to effectively cast a strong, Safe, economical and efficient inspection and maintenance methods are important. Technology improves the level of emergency response, quickly responds to scenarios such as complex environments, natural disasters, equipment hidden danger inspections, and prevents problems before they happen. The power grid needs a strong, effective, and refined inspection system!
• There is no public network signal in the cable tunnel, and the cost of deploying a fixed network system is high
• Complex environments such as metal doors and curves make it difficult to transmit real-time video during inspections
• High voltage level, large electromagnetic interference
• The public network signal near the substation is very poor, and the inspection video cannot be sent back through the public network
• Video surveillance business interaction data is large
• High real-time requirements
• The remote visual operation business requires a large amount of interactive data
Wireless broadband ad hoc networking (also called Mesh networking) adopts a centerless networking technology, which is a networking technology based on the principle of "equality and independence" for all nodes. There is no dependency relationship between nodes, and the networking and data transmission are carried out through negotiation with each other. Compared with the current network based on central nodes, the main advantages of non-central ad hoc network technology are:
1) Strong network robustness: capable of self-organization and self-recovery, high network stability and reliability;
2) Easy to deploy and install: It does not depend on any key nodes, can randomly deploy network topology, and can be used with one-click startup;
3) Flexible structure: automatic maintenance of network links, automatic routing calculation, etc.; new network nodes can be accepted at any time, and off-network nodes can also be deleted at any time, without configuration, and the network has high flexibility;
4) Same-frequency technology: the node frequency is the same, effectively saving spectrum resources;
5) Load balancing technology: According to the real-time load of the network, it automatically calculates and selects the appropriate end-to-end path to avoid congested areas;
6) Non-line-of-sight transmission: Multi-hop can guarantee seamless coverage in non-line-of-sight scenarios.
Power inspection solution
Electric power emergency communication command
Without relying on the 4G public network, it can quickly build a dedicated communication network within the range of 1-3KM, which can be used as a backpack and relay equipment, and cooperate with other equipment to complete functions such as voice calls, video calls, and data transmission.
Emergency ad hoc network communication module (the host can be carried with you, or incorporated into emergency communication command vehicles and other special vehicles for modification)
