The signal acquisition component collects lightning signals directed to the ground and transmits them to the lightning monitoring unit for processing and analysis. This information provides information on the lightning current status, providing a reference for subsequent lightning protection improvements. This facilitates lightning protection and disaster reduction efforts in areas prone to lightning, while also avoiding excessive lightning protection measures and reducing investment costs. This is explained in detail below.

[0030] See Figure 1 and Figure 4In one embodiment, the lightning protection device includes a lightning protection component 20, a signal acquisition component 30 and a lightning monitoring unit 10. The lightning protection component 20 is used to guide the lightning signal to the ground. The signal acquisition component 30 is used to collect the lightning signal guided to the ground by the lightning protection component 20 and transmit the lightning signal to the lightning monitoring unit 10. The lightning monitoring unit 10 processes and analyzes the collected lightning signal to obtain the status information of the lightning current, which provides a reference for subsequent lightning protection improvements, is conducive to the development of lightning protection and disaster reduction work in areas with high lightning incidence, and at the same time avoids excessive lightning protection measures and reduces investment costs.

[0031] In this embodiment, the lightning monitoring unit 10 includes an interface module, a signal preprocessing module and a microprocessor module. The output end of the microprocessor module is respectively connected to the input end of the interface module and the signal preprocessing module, and is used to provide an enable signal to the interface module and the signal preprocessing module. The interface module and the signal preprocessing module work under the action of the enable signal provided by the microprocessor module.

[0032] It should be noted that the enable signal is a control signal used to start or activate a function or device, that is, the interface module and the signal preprocessing module in this embodiment receive the enable signal from the microprocessor module to start working; Figure 1 and Figure 2 In the figure, the transmission path of the enable signal is represented by a dotted arrow, and the transmission path of the lightning signal is represented by a solid line.

[0033] In addition, in this embodiment, the input end of the interface module is connected to the output end of the signal acquisition component 30, the input end of the signal preprocessing module is connected to the output end of the interface module, and the input end of the microprocessor module is connected to the output end of the signal preprocessing module; the interface module receives the lightning signal collected by the signal acquisition component 30, and transmits the lightning signal to the signal preprocessing module, the signal preprocessing module preprocesses the lightning signal, and transmits the preprocessed lightning signal to the microprocessor module. After receiving the lightning signal, the microprocessor module reads it and calculates the value of the lightning current. It can monitor lightning according to the value of the lightning current, thereby providing a reference for subsequent lightning protection improvements and avoiding excessive lightning protection measures that increase project investment costs.

[0034] It should be noted that the signal acquisition component 30 is a lightning current sensor in this embodiment, and may be other forms of signal acquisition in some embodiments, and is not limited thereto.

[0035] See Figure 1In one embodiment, the lightning monitoring unit 10 further includes a clock synchronization module, the output end of which is connected to the input end of the microprocessor module, for providing the microprocessor module with the time stamp information of the lightning signal collected by the signal acquisition component 30 (lightning current sensor, the same below). After receiving the time stamp information, the microprocessor module times it to obtain the duration of the lightning current.

[0036] By setting the clock synchronization module, the duration of the lightning current and the time when the lightning occurs can be obtained, which can better monitor the lightning.

[0037] See Figure 1 In one embodiment, the lightning monitoring unit 10 also includes a storage module, which is bidirectionally connected to the microprocessor module, that is, the storage module can record the data obtained by the microprocessor module (lightning current size, lightning current duration and lightning occurrence time, the same below), and the microprocessor module can read the data stored in the storage module.

[0038] See Figure 1 In one embodiment, the lightning monitoring unit 10 further includes a communication module. The output and input of the microprocessor module are connected to the input and output of the communication module, respectively. Specifically, the input of the communication module is connected to the output of the microprocessor, and the output of the communication module is connected to the input of the microprocessor module. The communication module is configured to transmit data obtained by the microprocessor module to the monitoring platform and transmit operating instructions from the monitoring platform to the microprocessor module to implement parameter information setting. The microprocessor module sends an enable signal to the communication module. Upon receiving the enable signal, the communication module begins operation and transmits data obtained from the microprocessor module to the monitoring platform for subsequent display or further processing.

[0039] It should be noted that the communication module can communicate with the monitoring platform using a wired Ethernet communication method. In some embodiments, it can also be through a 433Hz wireless radio frequency communication method, etc., but is not limited thereto.

[0040] See Figure 2In one embodiment, the signal preprocessing module includes a filtering module, an amplifying module and a conversion module in sequence; the input end of the filtering module is connected to the output end of the interface module, and is used to receive the lightning signal transmitted by the interface module, and filter the lightning signal to filter out stray signals, thereby effectively improving the accuracy of subsequent microprocessor module analysis; the input end of the amplifying module is connected to the output end of the filtering module, and the input end of the conversion module is connected to the output end of the amplifying module. The amplifying module is used to receive the lightning signal after filtering by the filtering module, and maintain and amplify the lightning signal, and transmit the processed lightning signal to the conversion module, which converts the lightning signal into a digital signal under the action of the conversion module; the output end of the conversion module is connected to the input end of the microprocessor module, and transmits the converted digital signal to the microprocessor module for analysis to obtain data.

[0041] It should be noted that the output end of the microprocessor module is connected to the input ends of the filtering module, the amplifying module and the converting module respectively, and can transmit the enable signal of the microprocessor module to each module and enable each module to operate.

[0042] See Figure 3 In one embodiment, the lightning monitoring unit 10 also includes a power module, which includes a battery management circuit, a rechargeable battery, a solar panel and an inverter circuit; the input end of the battery management circuit is connected to the output end of the microprocessor module, and is used to receive and transmit battery management instruction information issued by the microprocessor module; the input end of the rechargeable battery is connected to the output end of the battery management circuit, and is used to receive an enable signal issued by the battery management circuit and supply power to each module through the output end of the rechargeable battery; one input end of the inverter circuit is connected to the output end of the solar panel, and another input end of the inverter circuit is connected to the output end of the battery management circuit.

[0043] It should be noted that when the power module is operating, the battery management circuit sends an enable signal, which activates the inverter circuit upon receipt, converting the light energy collected by the solar panel into electrical energy. This electrical energy not only directly powers the operation of the aforementioned modules but also charges the rechargeable battery. When the rechargeable battery is fully charged, the battery management circuit automatically stops charging upon receiving feedback to ensure the battery's performance. At night or in rainy weather, the battery management circuit automatically switches to rechargeable battery power mode, ensuring the normal operation of the lightning monitoring unit 10.

[0044] The power supply mode is a combination of rechargeable batteries and solar panels, which eliminates the need for external power supply. It is simple and convenient to install and use, and does not require special maintenance.

[0045] See Figure 4 In one embodiment, the lightning protection assembly 20 includes a down conductor 24 and a lightning induction structure. One end of the down conductor 24 is connected to the lightning induction structure, and the other end is connected to the grounding wire 26 through a disconnect card 25 to introduce the lightning signal into the ground.

[0047] In this embodiment, the lightning conductor structure includes a lightning conductor 22, which is arranged around the circumference of the top of the container and is spaced apart from the container through a support column 23. The down conductor 24 is connected to the lightning conductor.

[0048] It should be noted that the support column 23 is made of insulating material to ensure that there is no electrical connection between the lightning strip 22 and the container body; in addition, according to the requirements of the national standard GB50057-2010 "Code for Design of Lightning Protection of Buildings" for the second type of lightning protection buildings, the distance between two adjacent support columns 23 is less than 1000 mm, the height of the support column 23 is greater than 150 mm, and the down conductor 24 and the side wall of the container are also spaced by the support column 23. The parameters of the support column 23 are set according to the actual size of the container and the actual lightning protection requirements, which will not be repeated here.

[0049] In some embodiments, the lightning induction structure includes a lightning rod 21, which is connected to the down conductor 24 at one end close to the container and is spaced apart from the container through a support column 23; at least one group of lightning rods 21 is provided diagonally on the container, that is, the container is provided with two or four lightning rods 21. The number of lightning rods 21 is selected according to the historical statistical conditions of lightning strikes on site and the need for lightning protection, so as to provide effective lightning protection while avoiding excessive protection that increases project costs.

[0050] It should be noted that the specific height of the lightning rod 21 must be calculated and determined by referring to the rolling ball method in the national standard GB50057-2010 "Code for Design of Lightning Protection of Buildings".

In addition, through the arrangement of the lightning induction structure and the support column 23, the lightning current can be promptly directed to the ground for dispersion, thereby preventing the lightning current from entering the container and causing lightning failures in electrical equipment.

[0053] Before actual installation, the length of the lightning rod 21 and the length and spacing of the support columns 23 are determined in combination with on-site requirements and according to national standards; during installation, the lightning monitoring unit 10 is installed in the middle of the top surface of the container, and the signal acquisition component 30 is set on the grounding wire 26. The lightning monitoring unit 10 is set in the middle of the top surface to ensure that the distance from the lightning monitoring unit 10 to each signal acquisition component 30 is equal, which is conducive to the real-time collection of lightning signals.
