It should be noted that the following embodiments are only used to explain the present application and do not constitute a limitation to the present application.

[0062] Embodiment 1:

[0063] The present application relates to a lightning effect protection and monitoring terminal. It can be applied to equipment and facilities that require lightning effect protection. While protecting the equipment and facilities from lightning effects, it can detect in real time the direct or indirect effects of direct lightning on the assembly parts of the lightning protection device, and detect the protection effect of the protection device in real time, so as to realize the real-time monitoring of the health status of the lightning protection device, predict its remaining life cycle, reduce the probability of missed inspection and misjudgment in manual inspection, reduce the safety hazards caused by the failure to detect the deterioration of the lightning protection device in time, and improve the degree of intelligent maintenance management. See Figure 8 .

[0064] See Figure 1, a lightning effect protection and monitoring terminal, consists of two parts: a lightning effect protection and coupling component and a monitoring terminal. The lightning effect protection and coupling component undertakes the functions of lightning effect protection for the corresponding interfaces and lightning coupling output, and is functionally divided into a lightning effect protection network and a coupling network. The lightning effect protection network has corresponding circuit designs to match different interfaces, such as RF interfaces, power interfaces, bus interfaces, Ethernet interfaces, etc., in order to adapt and match different interfaces, and the coupling network circuit is also correspondingly different.

[0065] The lightning effect protection and monitoring terminal provided by this application is different from direct lightning monitoring systems such as dedicated lightning protection systems and lightning proximity warning systems. Instead, it conducts real-time detection of direct lightning or lightning effects on the assembly parts of lightning protection devices, real-time detection of the protection effects of protection devices, realizes real-time monitoring of the health status of lightning protection devices, uploads data, and conducts subsequent data processing and analysis.

[0066] The block diagram of the lightning effect protection and monitoring terminal is as Figure 1 shown, and it consists of two parts: a lightning effect protection and coupling component and a monitoring terminal. The lightning effect protection and coupling component undertakes the functions of lightning effect protection for the corresponding interfaces and lightning coupling output. The lightning effect protection and coupling component undertakes the functions of lightning effect protection for the corresponding interfaces and lightning coupling output.

[0067] The design scheme of the lightning effect protection and monitoring terminal is as Figure 2 shown. The overall design adopts a split design method. The lightning effect protection and coupling component and the monitoring terminal are connected by cables. According to different adaptation objects, the lightning effect protection and coupling component is divided into different forms such as RF system protection and coupling components, power system protection and coupling components, bus system protection and coupling components, Ethernet system protection and coupling components, etc., which can adapt to most lightning protection application scenarios. The monitoring terminal is a general-purpose design, adapts to the above various protection and coupling components, and has the advantages of scalability, maintainability, fault tolerance, and reliability.

[0068] If it is necessary to change the object of lightning protection, there is no need to completely replace the entire system. Only the protection and coupling components for the corresponding usage scenarios need to be replaced. The lightning effect protection and coupling component and the monitoring terminal are relatively independent of each other. The update and maintenance work can be limited to individual modules, reducing the time and cost of maintenance. The module itself also adopts a modular design, which helps to improve the reliability and fault tolerance of a single module. When a certain part in a single module fails, such a fault can be easily identified and isolated without affecting other parts of the module. The system can maintain the normal operation of some functions, thus reducing the risk of the entire system crashing. Especially for the application of critical facilities and equipment, this kind of fault tolerance and reliability is crucial.

[0069] The lightning effect protection and coupling components adopt an integrated design, which is compact in size. It can be conveniently installed between interfaces that require lightning effect protection without changing the original structure and installation method of the equipment and facilities, and has good compatibility. According to different adaptation objects, it is divided into different forms such as radio frequency system protection and coupling components, power system protection and coupling components, bus system protection and coupling components, and Ethernet system protection and coupling components.

It adopts a topology structure that combines a coupling network and a protection network. The coupling network is realized by using a radio frequency transmission line structure, and the discharge network is realized by using a filter suppression circuit, a gas discharge tube, and a coaxial transmission line structure. The input and output ends of the integrated component are connected to external radio frequency components through radio frequency connectors, and the coupling output is interconnected with the monitoring terminal through a radio frequency connector.

The input and output ends of the integrated component are connected to the external power supply and equipment through power connectors, and the coupling output is interconnected with the monitoring terminal through a low-frequency signal connector.

[0074] Bus system protection and coupling components

[0075] The functional topology of the bus system protection and coupling components is as Figure 5 shown. It adopts a topology structure that combines a coupling network and a protection network. The coupling network is realized by using a Hall sensor, the discharge network is realized by using a filter suppression circuit, a gas discharge tube, a varistor, or other combinations, and the clamping network is realized by using a TVS tube.

The input and output ends of the integrated component are connected to the external Ethernet using a network connector, and the coupled output is interconnected with the monitoring terminal using a low-frequency signal connector.

[0078] The monitoring terminal adopts an integrated design, with a compact and small volume and a lightweight weight, which is convenient for deployment and installation and does not affect the existing wiring and structural layout of the customer's equipment as much as possible. The appearance structure has various forms according to the specific installation scenario, such as rack-mounted, portable, etc. The portable type can be made into various product forms such as wall-mounted installation, clamping installation, threaded installation, clamp installation, plug-in installation, etc. according to the specific scenario. The product adopts a low-power design and does not increase the user's power consumption pressure. The terminal power interface is independently designed and can be replaced, and can be flexibly adapted according to the actual power supply situation of the user to meet the application requirements of various scenarios. The hardware block diagram of the monitoring terminal is as Figure 7 shown.

[0079] The acquisition module completes the adaptation, sorting and digital sampling of the externally input analog signal, and converts the input analog signal into a digital signal that can be digitally processed. The processing module completes functions such as signal processing, data storage, and network interface communication of the digital signal, and collects the lightning current, leakage current and other lightning impact signals of the input lightning-coupled signal in real time, analyzes the type of lightning strike, the working conditions and health status of the lightning protection device affected by the lightning strike. Record information such as the number of times and intensity of lightning strikes on the cumulative protection device, comprehensively evaluate the analysis results such as the health status and service life of the lightning protection device, and transmit these collected data and analysis results to the remote control center through the network interface to achieve the purpose of remote monitoring.
