Description

Technical Field

[0001] This utility model relates to the field of lightning protection technology, and in particular to a low-power switching output lightning strike counter. Background Technology

[0002] A lightning strike counter uses the induced voltage or current generated when lightning current passes through a conductor to drive the counter to count, so that managers can keep track of lightning activity and carry out preventive protection and hazard assessment.

[0003] Existing lightning strike counters use bolts to connect their circuit boards, but this makes disassembly / reinstallation complex when power is lost due to lightning strikes. The lightning strike data recorder cannot continue to work, affecting the statistics of lightning strikes and resulting in low accuracy of preventive protection and hazard assessment. Utility Model Content

[0004] The main purpose of this utility model is to provide a low-power switch output lightning strike counter, which aims to solve the problem that existing lightning strike counters use bolts to connect the circuit boards, making disassembly / installation inconvenient.

[0005] To achieve the above objectives, this utility model proposes a low-power digital output lightning strike counter, which includes:

[0006] The housing contains a continuous circuit indicator circuit board, an action count indicator circuit board, and a power supply circuit board.

[0007] The continuous circuit indicator circuit board, the action count indicator circuit board and the power supply circuit board are interconnected via headers / pin headers;

[0008] The action counting indicator circuit board includes an MCU, which is used to output normally open switch signals to the programmable terminal.

[0009] In one embodiment, the housing includes a waterproof top cover, a base, and a waterproof gasket. The waterproof top cover and the base are fixedly connected by screws, and the base is provided with a first mounting strip and a second mounting strip.

[0010] In one embodiment, the low-power switch output lightning strike counter further includes an equivalent inductor, a waterproof transparent junction box, and a third mounting strip;

[0011] The equivalent inductance is separately housed in the waterproof transparent junction box. When it is connected to the outer casing via the third mounting strip, the maximum discharge current of the lightning pulse is 70kA.

[0012] Alternatively, when the equivalent inductance is located inside the housing and is interconnected with the continuous circuit indicator circuit board, the action count indicator circuit board, and the power supply circuit board via the header / pin header, the maximum discharge current of the lightning pulse is 100kA.

[0013] In one embodiment, the power circuit board is provided with a lithium battery, which provides operating power to the continuous circuit indicator circuit board, the action count indicator circuit board and the equivalent inductor.

[0014] In one embodiment, the action counting indicator circuit board includes an MCU board layer, which is a four-layer PCB structure.

[0015] This utility model's technical solution uses headers / pin headers to interconnect the continuous circuit indicator circuit board, the action count indicator circuit board, and the power supply circuit board, facilitating installation / removal and preventing the low-power switch output lightning strike counter from malfunctioning when damaged. This ensures the authenticity and reliability of lightning strike data and improves the accuracy of preventative protection and hazard assessment. Furthermore, a microcontroller (MCU) outputs normally open switch signals for connection to a programmable terminal, enabling real-time remote monitoring of the status. Attached Figure Description

[0026] Existing lightning strike counters use bolts to connect their circuit boards, but this makes disassembly / reinstallation complex when power is lost due to lightning strikes. The lightning strike data recorder cannot continue to work, affecting the statistics of lightning strikes and resulting in low accuracy of preventive protection and hazard assessment.

[0027] To address the aforementioned problems, this invention proposes a low-power switch output lightning strike counter. The specific embodiments of this invention will be described in detail below with reference to the accompanying drawings.

[0028] like Figures 1-4 As shown, the low-power digital output lightning strike counter includes:

[0029] The housing contains a continuous circuit indicator circuit board, an action count indicator circuit board, and a power supply circuit board.

[0030] The continuous circuit indicator circuit board, the action count indicator circuit board and the power supply circuit board are interconnected via headers / pin headers;

[0031] The action counting indicator circuit board includes an MCU, which is used to output normally open switch signals to the programmable terminal.

[0032] In one embodiment, the housing includes a waterproof top cover, a base, and a waterproof gasket. The waterproof top cover and the base are fixedly connected by screws, and the base is provided with a first mounting strip and a second mounting strip.

[0033] In one embodiment, the power circuit board is provided with a lithium battery, which provides operating power to the continuous circuit indicator circuit board, the action count indicator circuit board and the equivalent inductor.

[0034] In this embodiment, headers / pin headers are used to connect the continuous circuit indicator circuit board, the action count indicator circuit board, and the power supply circuit board together for easy installation and disassembly. When the low-power switch output lightning strike counter loses power due to a lightning strike, it is convenient for maintenance personnel to disassemble / install it and quickly restore it to normal operation, avoiding affecting the statistics of the number of lightning strikes and improving the accuracy of preventive protection and hazard assessment.

[0035] In this embodiment, the outer casing consists of a waterproof top cover, a base, and a waterproof gasket. The waterproof top cover is fixedly connected to the base with screws. The base is provided with a first mounting strip and a second mounting strip, and is equipped with four 4*40mm screws and four 4mm nuts. The low-power switch output lightning strike counter is powered by an embedded lithium battery for the continuous circuit indicator circuit board, the action counting indicator circuit board, and the equivalent inductor.

[0036] This utility model relates to a low-power switch output lightning strike counter. The continuous circuit indicator circuit board, action count indicator circuit board, and power supply circuit board are interconnected via headers / pin headers for easy installation / removal. This prevents the low-power switch output lightning strike counter from malfunctioning due to damage, ensuring the authenticity and reliability of lightning strike data and improving the accuracy of preventative protection and hazard assessment. Furthermore, a microcontroller (MCU) outputs normally open switch signals for subsequent connection to a programmable terminal, enabling real-time remote monitoring of the status.

[0037] In one embodiment, the low-power switch output lightning strike counter further includes an equivalent inductor, a waterproof transparent junction box, and a third mounting strip;

[0038] The equivalent inductance is separately housed in the waterproof transparent junction box. When it is connected to the outer casing via the third mounting strip, the maximum discharge current of the lightning pulse is 70kA.

[0039] Alternatively, when the equivalent inductance is located inside the housing and is interconnected with the continuous circuit indicator circuit board, the action count indicator circuit board, and the power supply circuit board via the header / pin header, the maximum discharge current of the lightning pulse is 100kA.

[0040] In this embodiment, the equivalent inductor can be integrated into the housing or placed separately in a waterproof transparent junction box for flexible material preparation. The difference lies in the installation method. Due to limited space, when the equivalent inductor is placed separately in the waterproof transparent junction box and fixed to the down conductor or a 3*30mm flat steel / iron / copper strip via mounting strips, its inductance is relatively small, resulting in a lower electric field strength and a lightning pulse discharge current ≤70kA. However, when the equivalent inductor is integrated into the housing and interconnected with the continuous circuit indicator circuit board, the action count indicator circuit board, and the power supply circuit board via headers / pin headers, the maximum lightning pulse discharge current can reach 100kA.

[0041] In one embodiment, the action counting indicator circuit board includes an MCU board layer, which is a four-layer PCB structure.

[0042] In this embodiment, the MCU board adopts a four-layer PCB process. The four-layer PCB structure can improve the isolation and anti-interference effect and avoid the situation where the MCU is stuck due to magnetic saturation. A low-power microcontroller is provided on the MCU board to control the operation of the low-power switch output lightning strike counter. Low-power components are used to reduce power consumption and extend the battery life of the low-power switch output lightning strike counter.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
