HD-LDL Lightning Monitoring System
I. Basic Overview of Lightning Protection Systems
The HD-LDL Online Lightning Monitoring System is an advanced, high-tech system specifically designed to monitor and analyze lightning activities. Powered by big data and AI models, it provides equipment-free data services. The system can monitor key parameters in real time, including lightning current parameters, the degradation level of Surge Protective Devices (SPDs), operation counts, air switch statuses, three-phase voltages, as well as environmental temperature and humidity. It not only offers early warnings before lightning strikes but also provides post-strike traceability data for precise localization, significantly saving the time cost of accident investigation.
This system is specifically tailored for large-scale projects that are highly susceptible to lightning strikes and difficult to inspect accurately, such as forestry and grasslands, aerospace facilities, oil depots, wind farms, overhead transmission lines, highways, and communication networks. Through intelligent data monitoring and collection, it achieves the functions of empirical data accumulation and risk early warning.
II.Three-Tier Monitoring Structure of the Lightning Protection System
1.Central Management Center: Depending on the operating distance, it communicates with the mobile data collection devices at the system's monitoring substations either through direct retrieval or via a GPRS network to obtain real-time status information of all monitored points.
2.Handheld Mobile Collection Devices: Communicates wirelessly with the wireless data acquisition terminals and transmits the collected results to the Central Management Center.
3.Wireless Acquisition Terminals: Operates independently with automatic data collection and recording capabilities. Its data can be read at any time by inspectors' mobile devices, transmitted via fiber optics, or transferred using the GPRS system.
III.Features of the Lightning Protection System
Cost-Effective:Utilizes low-cost wireless transmission equipment,significantly reducing overall project construction costs.
Ultra-Low Power Consumption&Solar Powered:Operates with extremely low power consumption and is powered by photovoltaic(solar)energy,eliminating the need for additional power supply infrastructure.
