This utility model discloses a handheld portable lightning warning device, including a circuit board, a shell, a cover plate, a 4G antenna and a Beidou antenna, a signal receiving circuit, an alarm circuit, and a main control circuit. The main control circuit is connected to the 4G antenna, the Beidou antenna, the signal receiving circuit, and the alarm circuit. This utility model achieves positioning and tracking through the 4G antenna and the Beidou antenna, making it easier for users to identify directions in the wild or in areas with weak signals, thereby ensuring user safety. Furthermore, the signal receiving circuit, the main control circuit, and the alarm circuit sense early low-intensity weak discharges and noise changes of lightning within a range of 5-15 kilometers, providing timely audible and visual warnings of nearby or impending lightning discharges to remind users to take shelter from lightning and protect their safety.

The invention relates to a rapid positioning detection method for a high-precision pipeline route. The method comprises the following steps: S1, firstly, putting a detection device into a pipeline along the flowing direction of a fluid medium; s2, starting a measuring instrument of the head mechanism, performing data fusion by a Kalman filter, and transmitting the data to a control center of the head mechanism in real time; s3, opening a fan plate, and then starting propellers on the head mechanism and the propelling mechanism: the two mechanisms work together to realize the swimming and steering movement of the detection device in the pipeline, and detecting the condition in the pipeline by using a sensor; s4, when the head mechanism detects that the flow velocity in the pipeline changes suddenly, the sector plate is withdrawn, the position and range of the flow velocity change are recorded, a warning signal is sent out through a control center of the head mechanism, and then other parts in the pipeline continue to be detected; and if the signal cannot be sent, ending detection and immediately returning. According to the invention, the pipeline can be automatically, efficiently and automatically detected, the accuracy is high, the real-time performance is good, the labor cost is reduced, and the manual operation risk is reduced.
