Technical Field

[0001] This invention relates to the field of lightning information acquisition equipment technology, specifically to a near-field lightning information acquisition system. Background Technology

[0002] Currently available lightning information recorders only allow local viewing of lightning strike counts and times. They cannot collect, read, and save data from multiple lightning information recorders through a single acquisition terminal, nor can they copy the data from the acquisition terminal to a computer. Due to structural limitations, the protection level of lightning information recorders cannot meet the IP68 requirement, making them unsuitable for applications in certain industries and special occasions. Summary of the Invention

It can inspect multiple lightning information recorders through a single lightning information acquisition terminal, and automatically connect, acquire and store the lightning strike data in the lightning information recorders through magnetic control.

[0004] A near-field lightning information acquisition system includes a lightning information recorder, a lightning information acquisition terminal, and a lightning information communication module. The lightning information acquisition terminal is connected to the lightning information recorder via 2.4G wireless communication to synchronously transmit the data stored in the lightning information recorder to the lightning information acquisition terminal. The lightning information recorder is also connected to a computer via the lightning information communication module for modification or deletion operations. The lightning information recorder includes a lightning current sensor, a first wireless communication module, a first chip unit, and a Hall electromagnetic switch. The lightning current sensor is used to connect to the line through which the lightning current to be measured passes to sense lightning information. The lightning information acquisition terminal includes a second wireless communication module, a magnet, a display module, and a second chip unit; the first wireless communication module and the second wireless communication module are wirelessly connected; the Hall electromagnetic switch and the magnet constitute a magnetic control switch to generate magnetic control induction when the lightning information recorder and the lightning information acquisition terminal come into contact or approach each other, and provide corresponding communication control signals through their respective chip units to trigger the first wireless communication module and the second wireless communication module to automatically connect and communicate handshake. The lightning information communication module includes a communication chip, a third wireless communication module, and a data interface. The lightning information recorder communicates wirelessly with the third wireless communication module via the first wireless communication module to transmit data information. The lightning information communication module connects to a computer terminal via a USB connector. Preferably, the lightning information recorder can be operated on by using the built-in lightning information reading software on the computer, through the connection and communication between the USB connector and the lightning information communication module, including operations such as name entry, serial number deletion, and data deletion.

[0005] Preferably, the first wireless communication module, the second wireless communication module, and the third wireless communication module are all 2.4G wireless communication modules. Further, the lightning information recorder also includes a first battery pack for power supply, and the lightning information acquisition terminal also includes a second battery pack for power supply.

[0006] Furthermore, the lightning information recorder is wirelessly connected to the lightning information communication module via the first wireless communication module. The lightning information communication module is connected to a computer or electronic terminal via a USB plug to change the name, serial number, and delete data of the lightning information recorder on the computer or electronic terminal. The computer or electronic terminal has built-in dedicated lightning information reading software, which displays and copies the lightning strike data collected in the acquisition terminal to the computer or electronic terminal to achieve remote viewing, management, and storage.

[0007] Furthermore, the lightning current sensor has a mounting clip, which is used to attach the lightning current sensor to the monitored conductor to collect the lightning current of the conductor; the mounting clip is a detachable clip, and the lightning current sensor also has a housing and an air-core coil, the air-core coil being sealed and bonded to the housing with epoxy resin; the mounting clip is a ring-shaped clip that can cover the cross-section of the conductor, the ring-shaped clip has an open-loop structure, and has a clip portion and a protruding part protruding from the clip portion at the edge of the open loop.

[0008] Furthermore, the lightning recorder also includes a driving circuit, a first calendar / clock / crystal oscillator system circuit, and a recording register; the driving circuit is connected to the lightning current sensor to receive the pulse signal collected by the lightning current sensor and convert the pulse signal into a switching signal and then send it to the first chip unit; the first chip unit cooperates with the first calendar / clock / crystal oscillator system circuit to superimpose a time data on each switching signal each time a switching signal is input, and saves the switching signal with superimposed time data to the recording register for storage.

[0009] Furthermore, the lightning information acquisition terminal also includes function buttons, an acquisition register, and a second calendar / clock / crystal oscillator system circuit. The first wireless communication module and the second wireless communication module communicate under the trigger of a magnetic switch and synchronize all data in the recording register to the acquisition register for storage through a communication protocol. The acquired and stored lightning strike data information can be viewed and previewed through the function buttons and the display module.

[0010] Preferably, when the lightning information acquisition terminal is magnetically connected to the lightning recorder, the clock information of the lightning information acquisition terminal is automatically synchronized to the lightning recorder to provide time synchronization for the lightning recorder and correct the time error of the lightning recorder.

[0011] Furthermore, the lightning information recorder has a non-metallic waterproof box. The lightning current sensor is externally placed in the waterproof box and is snapped onto the monitored conductor by a mounting clip on the lightning current sensor. All circuits, components, and accessories inside the lightning information recorder are integrated into the waterproof box and sealed with epoxy resin.

[0013] Preferably, the lightning information recorder has a recording register and can store up to 9999 lightning strike data points. It can simultaneously record and save the number of lightning strikes and the time of lightning strikes, and has a power-off retention function. The outer shell of the lightning information recorder is made of a shell that meets the IP68 protection level and the V0 flame retardant level.

[0014] In the aforementioned near-field lightning information acquisition system, a Hall effect electromagnetic switch and the magnet form a magnetic control switch to realize the near-field communication switch function. As long as they are slightly close, the lightning information acquisition terminal and the lightning information recorder can quickly and automatically communicate, identify, and interconnect, facilitating data acquisition and transmission. This allows maintenance personnel to collect, read, and save data stored in multiple lightning information recorders using a single handheld lightning information acquisition terminal. Meanwhile, the lightning information acquisition terminal has a display module and function buttons, allowing users to query and delete data stored in the lightning information recorder. Data collected by the handheld lightning information acquisition terminal can be connected to a computer via USB, and then, using dedicated reading software (such as built-in lightning information reading software), the lightning strike data collected by the acquisition terminal can be displayed and copied to the computer for viewing, management, and storage. Alternatively, a USB-to-2.4G communication module (i.e., a lightning information communication module) can be used to connect the computer and dedicated reading software to the lightning information recorder. Through software (such as built-in lightning information reading software), the name and code of the lightning information recorder can be changed and customized, providing users with a visual, standardized, data-driven, and intuitive user experience, enabling efficient, fast, and convenient maintenance. Therefore, the above-mentioned near-field lightning information acquisition system can meet the practical engineering application scenarios of some special industries and special occasions. For example, it simultaneously meets the requirements for outdoor use (meeting IP68 waterproof performance), is passive (internal power supply, no external power supply required), and has a counter capable of recording and storing data such as the number of lightning strikes and the time of lightning strikes, showing broad application prospects.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 and Figure 2 This illustration shows the framework structure of each module in the near-field lightning information acquisition system provided by an embodiment of the present invention, including a lightning information recorder, a lightning information acquisition terminal, and a lightning information communication module. The lightning information acquisition terminal is communicatively connected to the lightning information recorder to synchronously transmit the data stored in the lightning information recorder to the lightning information acquisition terminal. The lightning information recorder is also connected to a computer through the lightning information communication module for modification or deletion operations. The lightning information recorder includes a lightning current sensor, a first wireless communication module, a first chip unit, and a Hall effect electromagnetic switch. The lightning current sensor is used to connect to the lightning current channel under test to sense lightning information. The lightning information acquisition terminal includes a second wireless communication module, a magnet, a display module, and a second chip. The unit comprises: a first wireless communication module and a second wireless communication module wirelessly connected; a Hall effect electromagnetic switch and a magnet forming a magnetic control switch for generating magnetic induction when the lightning information recorder and the lightning information acquisition terminal come into contact or approach each other, and providing corresponding communication control signals through their respective chip units to trigger the first wireless communication module and the second wireless communication module to automatically connect and handshake for communication; the lightning information communication module includes a communication chip, a third wireless communication module, and a data interface; the lightning information recorder wirelessly communicates with the third wireless communication module through the first wireless communication module to transmit data information; and the lightning information communication module connects to a computer or electronic terminal through the data interface to realize the modification or deletion operation.

[0021] Preferably, the first wireless communication module, the second wireless communication module, and the third wireless communication module are all 2.4G wireless communication modules. Specifically, the lightning information recorder and the lightning information acquisition terminal use a Hall effect electromagnetic switch and a magnet to trigger the 2.4G wireless communication function, synchronously transmitting the data stored in the lightning information recorder to the lightning information acquisition terminal. If a computer can communicate wirelessly with the lightning information recorder via the lightning information communication module using 2.4G, and uses dedicated lightning information reading software, it can edit and store the lightning information recorder's serial number and device name. In specific applications, the magnet of the lightning information acquisition terminal is a built-in permanent magnet. By placing the top of the lightning information acquisition terminal against the center of the lightning information recorder's panel, it can automatically connect and read the lightning information data stored in the recorder. Specifically, the computer or electronic terminal has built-in dedicated lightning information reading software. This software displays and copies the lightning strike data collected by the acquisition terminal to the computer or electronic terminal for remote viewing, management, and storage.

[0022] Furthermore, the lightning information recorder also includes a first battery pack for powering it, preferably a 3.6V / 10400mAh lithium-ion battery pack, giving the lightning information recorder a theoretical battery life of 10-15 years without maintenance. The lightning information acquisition terminal also includes a second battery pack for powering it, preferably a rechargeable battery.

[0023] Furthermore, the lightning current sensor has a mounting clip, which is used to attach the lightning current sensor to the monitored conductor to collect the lightning current of the conductor; the mounting clip is a detachable clip, and the lightning current sensor also has a housing and an air-core coil, the air-core coil being sealed and bonded to the housing with epoxy resin.

[0024] Furthermore, the lightning recorder also includes a drive circuit, a first calendar / clock / crystal oscillator system circuit, and a recording register. The drive circuit is connected to the lightning current sensor to receive the pulse signal collected by the lightning current sensor and converts the pulse signal into a switching signal, which is then sent to the first chip unit. Each time a switching signal is input, the first chip unit collaborates with the first calendar / clock / crystal oscillator system circuit to superimpose a time data onto each switching signal and saves the switching signal with superimposed time data to the recording register for storage. Furthermore, the lightning information recorder has a non-metallic waterproof housing. The lightning current sensor is externally mounted in the waterproof housing and is secured to the monitored wire by a mounting clip on the lightning current sensor. All circuits, components, and accessories inside the lightning information recorder are integrated within the waterproof housing and sealed with epoxy resin.

[0025] like Figure 3 and Figure 4 As shown, the mounting clip is a ring-shaped clip that can cover the cross-section of the wire.

Preferably, the lightning information recorder has a recording register capable of storing up to 9999 lightning strike data entries, and features power-off data retention; when the storage space is full, historical records are overwritten sequentially. The outer casing of the lightning information recorder meets IP68 protection standards and V0 flame retardant rating.

[0026] Furthermore, the lightning information acquisition terminal also includes function buttons, an acquisition register, and a second calendar / clock / crystal oscillator system circuit. The first wireless communication module and the second wireless communication module communicate under the trigger of a magnetic switch and synchronize all data in the recording register to the acquisition register for storage through a communication protocol. The acquired and stored lightning strike data information can be viewed and previewed through the function buttons and the display module.

[0027] Preferably, when the lightning information acquisition terminal is magnetically connected to the lightning recorder, its clock information is automatically synchronized to the lightning recorder to provide time synchronization and correct time errors. Further, the lightning information acquisition terminal includes a USB interface for direct data transmission to a computer. A wired connection to the computer via the USB interface allows for one-click synchronization of the computer's clock information to the lightning information acquisition terminal and processing of the lightning information stored on the terminal. The lightning information acquisition terminal and computer are wired via a USB cable. Using dedicated software, the computer's clock information can be synchronized to the lightning information acquisition terminal with one click, stored lightning information can be deleted with one click, the name of the lightning information acquisition terminal can be edited, and lightning information saved in the terminal can be copied, copied, and archived to the computer. Therefore, the Lightning Information Communication Module is a relay communication device specifically designed for one-to-one communication between a computer and a Lightning Information Recorder. The Lightning Information Communication Module is inserted into the computer's USB port via a USB interface terminal and can communicate wirelessly with the Lightning Information Recorder via 2.4G using dedicated software. It can also edit the serial number and device name of a Lightning Information Recorder.

[0032] 5) Automatically identifies and distinguishes lightning information from various lightning information recorders, making it simple, clear, and easy to understand.

[0033] 6) The lightning information acquisition terminal can clear, set, or select the number of lightning strike data stored in the lightning information recorder.
