[0026] To address the aforementioned problems, this utility model proposes a handheld portable lightning warning device. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-2 As shown, the handheld portable lightning warning device includes:

[0028] The circuit board 1, housing 2, cover plate 3, 4G antenna 15 and Beidou antenna 15 are provided. The circuit board 1 is installed in the groove inside the housing 2 and sealed inside the housing 2 by the cover plate 3. The housing 2 is detachably connected to the mounting base.

[0029] A signal receiving circuit 11 is disposed on the circuit board 1, and the signal receiving circuit 11 is used to receive lightning signals;

[0030] An alarm circuit 14 is provided on the circuit board 1, and the alarm circuit 14 is used to output a corresponding alarm signal when working;

[0031] The main control circuit 13 is located on the circuit board 1. The input terminal of the main control circuit 13 is connected to the signal receiving circuit 11, and the output terminal of the main control circuit 13 is connected to the alarm circuit 14. The main control circuit 13 is also connected to the 4G antenna 15 and the Beidou antenna 15 respectively. The main control circuit 13 is used to control the alarm circuit 14 to work according to the lightning signal and output the corresponding alarm signal.

[0032] In one embodiment, the handheld portable lightning warning device further includes a signal amplification circuit 12, the input terminal of which is connected to the signal receiving circuit 11, and the output terminal of which is connected to the main control circuit 13. The signal amplification circuit 12 is used to amplify the lightning signal and output it to the main control circuit 13.

[0033] In one embodiment, the handheld portable lightning warning device further includes a battery 16 and a power switch button 17. The power switch button 17 is located on the housing 2. When activated, the power switch button 17 enables the battery 16 to provide operating power to the signal receiving circuit 11, the alarm circuit 14, and the main control circuit 13.

[0034] In this embodiment, the outer shell 2 is detachably connected to the mounting base. After the outer shell 2 and the mounting base are separated, the volume is reduced so that it can be carried around. Specifically, the outer shell 2 is placed on a horizontal platform, and the side wing is pressed to slide the outer shell 2 out, thereby removing the outer shell 2 from the mounting base.

[0035] In this embodiment, the signal receiving circuit 11 can be implemented using any signal receiving circuit 11 capable of receiving lightning signals, such as a loop antenna or a broadband magnetic antenna, to receive lightning signals in the long-wavelength range of radio waves; the signal amplification circuit 12 can be implemented using any signal amplification circuit 12 capable of amplifying lightning signals, such as a CMOS operational amplifier, to amplify the lightning signals so that the main control circuit 13 can perform subsequent processing; the alarm circuit 14 can be implemented using any alarm circuit 14 capable of outputting corresponding alarm signals during operation, such as a flashlight and / or a buzzer 144; the main control circuit 13 can be implemented using MCU, DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), SOC (System On Chip), etc.

[0036] Understandably, when a user notices poor weather or the potential for thunderstorms, they can press the power switch button 17 to provide power to the circuit board 1. The handheld portable lightning warning device then senses and receives weak discharge phenomena and noise changes within the clouds over a radius of 5-15 kilometers. The signal receiving circuit 11 receives the lightning signal, which is then amplified by the signal amplification circuit 12 and sent to the main control circuit 13. The main control circuit 13 controls the alarm circuit 14 to operate based on the lightning signal, meaning that the alarm circuit 14 outputs a corresponding alarm signal based on the voltage intensity, frequency, and amount of the lightning signal. For example, when the discharge phenomenon is weak and the noise... When the discharge level is very low, the alarm circuit 14 is deactivated. When the discharge phenomenon reaches a certain frequency, intensity, and threshold, the flashing light flashes, emitting a low-intensity warning signal to remind the user that lightning is approaching. When the dark discharge or strong discharge phenomenon in the clouds is severe and getting closer to people, the flashing light flashes and the buzzer 144 sounds, urging the user to be aware of the lightning danger and leave the work site as soon as possible. This timely reminder helps the user avoid lightning, protects the user's life, and reduces the losses caused by lightning. After using the handheld portable lightning warning device, the user can press the power switch button 17 again to stop the power supply, saving energy and reducing energy consumption.

[0037] In this embodiment, data transmission and high-precision positioning can be achieved through the 4G antenna 15 and the Beidou antenna 15. That is, when the user is in the wild or in an area with weak signal, the 4G antenna 15 and the Beidou antenna 15 can be used for positioning and tracking to ensure the user's safety.

[0038] This utility model of a handheld portable lightning warning device uses a 4G antenna 15 and a Beidou antenna 15 to achieve positioning and tracking, making it easier for users to identify directions in the wild or in areas with weak signals, thereby ensuring user safety. Furthermore, through the signal receiving circuit 11, the main control circuit 13, and the alarm circuit 14, it senses early low-field-strength weak discharges and noise changes of lightning within a range of 5-15 kilometers, and promptly provides audible and visual warnings for nearby or impending lightning discharges, reminding users to take timely shelter from lightning and protecting their safety.

[0039] In one embodiment, the alarm circuit 14 includes a first LED light-emitting diode 141, a second LED light-emitting diode 142, a third LED light-emitting diode 143, and a buzzer 144;

[0040] The main control circuit 13 is used to control the first LED 141, the second LED 142, and the third LED 143 to flash alternately at a first flashing frequency when the voltage value of the lightning signal exceeds a first preset voltage value and is lower than a second preset voltage value, and the frequency of the lightning signal exceeds a first preset frequency value and is lower than a second preset frequency value; and to control the first LED 141, the second LED 142, and the third LED 143 to flash alternately at a second flashing frequency and to control the buzzer 144 to sound when the voltage value of the lightning signal exceeds the second preset voltage value and the frequency of the lightning signal exceeds the second preset frequency value.

[0041] In this embodiment, the main control circuit 13 controls the alarm circuit 14 to operate based on the voltage and frequency of the received lightning signal, so as to output a corresponding alarm signal. Specifically, when the voltage value of the lightning signal is lower than the first preset voltage value and the frequency is lower than the first preset frequency value, the discharge phenomenon is weak and the noise is low. At this time, the first LED 141, the second LED 142, the third LED 143 and the buzzer 144 do not work. When the voltage value of the lightning signal exceeds the first preset voltage value and is lower than the second preset voltage value, and the frequency exceeds the first preset frequency value and is lower than the second preset frequency value, the nearby air discharge phenomenon reaches a certain frequency intensity and threshold. In this case, the main control circuit 13 controls the first LED to light up. LED 141, LED 142, and LED 143 flash alternately at a first flashing frequency of 0.5 to 1 flashes per second, emitting a low-intensity warning signal to alert users to the approaching lightning. When the voltage value of the lightning signal exceeds a second preset voltage value and the frequency of the lightning signal exceeds a second preset frequency value, indicating severe dark or strong discharge in the clouds and approaching the user, the main control circuit 13 controls the first LED 141, second LED 142, and third LED 143 to flash alternately at a second flashing frequency of 2 to 3 flashes per second, and controls the buzzer 144 to sound a rapid, short "beep beep" sound to urge the user to leave the area as soon as possible. The first preset voltage value, second preset voltage value, first preset frequency value, and second preset frequency value can be set according to actual conditions.

[0042] In one embodiment, the handheld portable lightning warning device further includes a fixing component for fixing the outer shell 2 to the cover plate 3.

[0043] In one embodiment, the fastener is a screw.

[0044] In this embodiment, the outer shell 2 can be made of a waterproof transparent box; the fixing parts can be made of screws. Specifically, the circuit board 1 of the handheld portable lightning warning device is provided with functional circuits such as a signal receiving circuit 11, a main control circuit 13, a battery 16, and an alarm circuit 14. The circuit board 1 is placed in the groove inside the outer shell 2. After the cover plate 3 is covered, the outer shell 2 and the cover plate 3 are fixedly connected by screws on both sides to complete the preparation of the handheld portable lightning warning device.

[0045] 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.
