Description

Technical Field

[0001] The present invention relates to the field of lightning waveform technology, and in particular to a method and system for collecting, transmitting, storing and displaying lightning waveforms. Background Art

[0002] Lightning disasters seriously affect human life and production activities, and lightning characteristic parameters are an important basis for lightning fault analysis, lightning protection design and measure application.

[0003] Lightning characteristic parameters are obtained by collecting lightning impulse waveforms on site and then analyzing lightning parameters such as amplitude, wavefront time, half-peak time, duration, energy and frequency of the lightning impulse waveform to obtain statistical characteristics of lightning impulses. This provides a basis for formulating lightning inspection standards for communication equipment, determining impulse test waves for communication equipment, unifying test methods, developing protection components, and selecting lightning protection measures.

[0004] Oscilloscopes already available on the market can sample waveform data, but these consume a lot of power, requiring reduction. Existing oscilloscopes are also large and require miniaturization. This problem arises because existing oscilloscopes primarily serve as instrumentation devices, requiring high performance for processing various waveform data, necessitating a large size and high power consumption. Traditional oscilloscopes only perform simple data acquisition and forward data via LAN or Wi-Fi, but lack dual-mode wireless satellite and terrestrial communication modules for data forwarding and transmission. Furthermore, lightning waveforms are transient, making them difficult to recover. If data is not captured, it is essentially lost. Marketed instruments lack robust protection mechanisms for data transmission. Summary of the Invention

[0005] The present invention proposes a lightning waveform collection, transmission, storage, and display method and system to solve the problem that the existing database has no lightning waveform data and cannot provide the induced voltage design guide according to the standard lightning rod.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Lightning waveform acquisition, transmission, storage, and display system, the hardware components include: integrated acquisition, storage, and communication instruments, communication network, and cloud server / database / early warning platform;

[0008] A method for collecting, transmitting, storing and displaying lightning waveforms includes the following steps:

[0009] Step 1: The sampling and storage module collects the lightning voltage-time point data converted by the transformer;

[0010] Step 2: The satellite and ground dual-mode communication module transmits the summary value of the lightning voltage-time point data, the formatted transmission data of the lightning voltage-time point, and the location identification tag of the lightning voltage-time point data to the cloud server / database / early warning platform based on the independently designed and constructed lightning data transmission strategy;

[0011] Step 3: The cloud server / database / warning platform stores the summary value of the lightning voltage-time point data, the formatted transmission data of the lightning voltage-time point, and the location identification tag of the lightning voltage-time point data;

[0012] Step 4: The early warning data analysis module obtains the lightning voltage-time point data in the database through the internal interface, and regularly outputs it to form an analysis report for display.

[0013] The beneficial effects of the present invention are as follows:

[0014] First: The present invention has the ability to output objective data on lightning waves in nature and form a real database, and can provide induced voltage design of lightning rods based on specifications, so as to make the technical parameters of lightning rods conform to objective natural conditions, optimize and improve the technical parameter specifications of lightning rods, and reduce the probability of fire safety accidents caused by unqualified lightning rod manufacturers.

[0015] Second: Use the foolproof protection mechanism of the wireless dual-mode satellite and ground communication modules, give priority to ground network transmission, and when there is no ground network signal, switch to the second transmission channel - satellite network transmission. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 This is a schematic diagram of the hardware composition and implementation process for lightning waveform acquisition, transmission, storage, and display. DETAILED DESCRIPTION

[0017] Example 1:

[0018] The hardware composition and implementation process principle of lightning waveform acquisition, transmission, storage and display, such as Figure 1 As shown, the hardware components include: integrated collection, storage and communication instruments, communication network and cloud server / database / early warning platform;

[0019] The implementation process principle of lightning waveform acquisition, transmission, storage, and display is as follows:

[0020] The lightning current is introduced through a lightning rod. A lead is installed on the lightning rod and connected to a current attenuator. The current attenuator scales the lightning current by a certain ratio. The scaled current passes through the mutual inductance coil to convert the current into voltage. The sampling and storage module collects the lightning voltage-time point data after the mutual inductance conversion.

[0021] The acquisition, storage, and communication instrument includes an acquisition and storage module, a satellite-ground dual-mode communication module, and a multi-band antenna. The acquisition and storage module has a built-in communication interface that forms an internal communication link with the satellite-ground dual-mode communication module. The acquisition and storage module sends the lightning voltage-time data of the sampling point through the multi-band antenna of the satellite-ground dual-mode communication module, and forwards the data to the cloud server / database / early warning platform through the operator's ground network or satellite communication network.

[0022] The cloud server / database / early warning platform includes a cloud server equipped with a database and an early warning data analysis and display module. The early warning data analysis module obtains lightning voltage and corresponding time point data in the database through an internal interface and regularly outputs analysis reports.

[0023] The satellite and ground dual-mode communication module has a built-in anti-misuse protection mechanism, which gives priority to transmitting lightning voltage-time point data through the operator's ground network and based on the independently designed and constructed lightning data transmission strategy. When it is determined that there is no operator's ground network signal, the lightning voltage-time point data transmission operation is completed through the satellite communication network based on the independently designed and constructed lightning data transmission strategy.
