[0019] To solve the above problems, the present invention proposes a handheld portable lightning warning device. The following will describe the specific implementation manners of the present invention in detail with reference to the accompanying drawings.

[0020] As Figure 1-2 shown, the handheld portable lightning warning device includes: A circuit board 1, a housing 2, a cover plate 3, a 4G antenna 15 and a Beidou antenna 15. The circuit board 1 is installed in a groove inside the housing 2 and sealed in the housing 2 through the cover plate 3. The housing 2 is detachably connected to the installation base; A signal receiving circuit 11, provided on the circuit board 1, and the signal receiving circuit 11 is used for receiving lightning signals; An alarm circuit 14, provided on the circuit board 1, and the alarm circuit 14 is used for outputting corresponding alarm signals during operation; A main control circuit 13, provided on the circuit board 1. The input end of the main control circuit 13 is connected to the signal receiving circuit 11, the output end of the main control circuit 13 is connected to the alarm circuit 14, and the main control circuit 13 is also respectively connected to the 4G antenna 15 and the Beidou antenna 15. The main control circuit 13 is used for controlling the operation of the alarm circuit 14 according to the lightning signals and outputting corresponding alarm signals.

[0021] In an embodiment, the handheld portable lightning warning device further includes a signal amplification circuit 12. The input end of the signal amplification circuit 12 is connected to the signal receiving circuit 11, and the output end of the signal amplification circuit 12 is connected to the main control circuit 13. The signal amplification circuit 12 is used for amplifying the lightning signals and then outputting them to the main control circuit 13.

[0022] 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 disposed on the housing 2. When the power switch button 17 is actuated, the battery 16 provides operating power to the signal receiving circuit 11, the alarm circuit 14, and the main control circuit 13.

[0023] In this embodiment, the housing 2 is detachably connected to the mounting base. After the housing 2 and the mounting base are disassembled, the volume is reduced to facilitate carrying around. Specifically, when the housing 2 is placed on a horizontal tabletop and the wing piece is pressed, the housing 2 can be slid out to disassemble the housing 2 from the mounting base.

[0024] In this embodiment, the signal receiving circuit 11 can be implemented by any signal receiving circuit 11 capable of receiving lightning signals, such as a loop antenna or a broadband magnetic antenna, etc., to receive lightning signals in the medium and long wave bands of radio; the signal amplification circuit 12 can be implemented by any signal amplification circuit 12 capable of amplifying lightning signals, such as a CMOS operational amplifier, etc., to amplify the lightning signals for subsequent processing by the main control circuit 13; the alarm circuit 14 can be implemented by any alarm circuit 14 capable of outputting corresponding alarm signals during operation, such as a flash lamp and / or a buzzer 144; the main control circuit 13 can be implemented by an MCU, a DSP (Digital Signal Process, digital signal processing chip), an FPGA (Field Programmable Gate Array, programmable logic gate array chip), an SOC (System On Chip, system-level chip), etc.

[0025] It is understandable that when the user perceives poor weather and unsafe factors such as thunderstorms, they can press the power switch button 17 to supply working power to the circuit board 1. The handheld portable lightning warning device senses and receives the weak discharge phenomena and noise changes in the sky clouds within a range of 5 to 15 kilometers around it, receives lightning signals through the signal receiving circuit 11, amplifies and processes the lightning signals through the signal amplification circuit 12, and then transmits them to the main control circuit 13. The main control circuit 13 controls the alarm circuit 14 to work according to the lightning signals, that is, makes the alarm circuit 14 output corresponding alarm signals according to the voltage intensity and quantity frequency of the lightning signals. For example, when the discharge phenomenon is weak and the noise is very low, it controls the alarm circuit 14 not to work. When the discharge phenomenon reaches a certain frequency intensity and threshold, the flashing light flashes and emits a low-intensity warning signal to remind the user to pay attention that lightning is coming soon; when the dark discharge or strong discharge phenomenon in the sky clouds is relatively serious and getting closer and closer to people, the flashing light flashes and the buzzer 144 sounds to urge the user that there is a lightning danger and they need to leave the work site as soon as possible, so as to timely remind the user to avoid lightning, protect the user's life safety, and reduce the losses caused by lightning; after the handheld portable lightning warning device is used up, the user presses the power switch button 17 again to stop power supply to save electric energy and reduce energy consumption.

[0026] 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 signals, the 4G antenna 15 and the Beidou antenna 15 can be used for positioning and tracking to ensure the safety of the user.

[0027] The handheld portable lightning warning device of the present invention realizes positioning and tracking through the 4G antenna 15 and the Beidou antenna 15, which is convenient for the user to identify the direction in the wild or in places with weak signals, thereby ensuring the safety of the user; and through the signal receiving circuit 11, the main control circuit 13 and the alarm circuit 14, it senses the early low-field-strength weak discharge and noise changes of lightning within a range of 5 to 15 kilometers, and timely gives an audible and visual warning of the lightning air discharge phenomenon that has occurred or is about to come nearby to remind the user to avoid lightning in time and protect the user's safety.

[0028] In one embodiment, the alarm circuit 14 includes a first LED light-emitting tube 141, a second LED light-emitting tube 142, a third LED light-emitting tube 143 and a buzzer 144; The main control circuit 13 is configured to control the first LED light-emitting diode 141, the second LED light-emitting diode 142, and the third LED light-emitting diode 143 to alternately flash 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. 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, control the first LED light-emitting diode 141, the second LED light-emitting diode 142, and the third LED light-emitting diode 143 to alternately flash at a second flashing frequency and control the buzzer 144 to sound.

[0029] In this embodiment, the main control circuit 13 controls the alarm circuit 14 to work according to the voltage and frequency of the received lightning signal to output corresponding alarm signals. 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, that is, the discharge phenomenon is weak and the noise is low, at this time, the first LED light-emitting diode 141, the second LED light-emitting diode 142, the third LED light-emitting diode 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, that is, when the nearby air discharge phenomenon reaches a certain frequency intensity and threshold, the main control circuit 13 controls the first LED light-emitting diode 141, the second LED light-emitting diode 142, and the third LED light-emitting diode 143 to alternately flash at a first flashing frequency of 0.5 - 1 times per second, emitting a low-intensity warning signal to remind the user to pay attention to the approaching lightning. 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, that is, when the dark discharge or strong discharge phenomenon in the air cloud is relatively serious and getting closer to the user, the main control circuit 13 controls the first LED light-emitting diode 141, the second LED light-emitting diode 142, and the third LED light-emitting diode 143 to alternately flash at a second flashing frequency of 2 - 3 times per second, and controls the buzzer 144 to sound, emitting a short and rapid "beep" sound to urge the user to leave the scene as soon as possible. Among them, the first preset voltage value, the second preset voltage value, the first preset frequency value, and the second preset frequency value can be set according to the actual situation.

[0030] In one embodiment, the handheld portable lightning warning device further includes a fixing member for fixedly connecting the housing 2 and the cover plate 3.

[0031] In one embodiment, the fixing member is a screw.

[0032] In this embodiment, the outer shell 2 can be implemented by a waterproof transparent box; the fixing member can be implemented by screws. Specifically, on the circuit board 1 of the handheld portable lightning warning device, there are 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 covering the cover plate 3, 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.

[0033] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
