Description

Technical Field

[0001] The present invention relates to the field of atmospheric environment monitoring emergency technology, and in particular to an atmospheric environment monitoring emergency warning device and a warning method thereof. Background Art

[0002] Atmospheric environmental monitoring plays a vital role in warning of extreme weather and preventing its hazards. By collecting atmospheric data such as temperature, humidity, wind speed, and direction, it can assess weather changes and issue warnings, giving people time to prepare for extreme weather events. Existing atmospheric monitoring and emergency warning equipment is large and often installed atop buildings to ensure data reliability, making it unsuitable for home use. Common household monitoring and warning equipment is used within the intelligent monitoring systems of smart homes. As intelligent devices that coordinate other execution systems within the Internet of Things, their primary function is to autonomously detect environmental changes, effectively warn of extreme weather events, and independently formulate protective measures. However, existing early warning equipment ignores the interference of inertia on detection accuracy, causing the detection data to deviate from the actual situation, seriously affecting the credibility of the warning. It is difficult for the public to make correct decisions based on unreliable warnings. When encountering a real warning, they ignore it because the previous warning is unreliable, resulting in threats to the safety of public life and property. In addition, the detection angle of existing early warning equipment is mostly adjusted manually, resulting in a fixed detection angle during operation, unable to track wind direction changes in real time, making the collected wind direction data inaccurate, affecting the reliability of the warning. Moreover, the detection angle cannot be automatically adjusted according to environmental changes. When the wind direction changes, the wind speed detection fan's windward angle cannot be adjusted in time, which increases the error of the detection data, reduces the reliability and timeliness of the warning, and greatly reduces the warning effect. Therefore, the present invention improves the existing equipment in view of the above problems. Summary of the Invention

The cooperation of the detection component and the transmission component facilitates early warning of weather changes and controls the operation of other equipment, realizing the ability to warn and automatically prevent extreme weather in advance. This ultimately solves the problem of fixed detection angles and single detection capabilities of existing equipment. The analysis module analyzes the rotation angle data to determine the frequency of wind direction changes at the monitoring location. The analyzed adjustment time is compared with the wind direction change frequency. If the adjustment time is longer than the wind direction change time, no adjustment operation is performed, thus avoiding invalid adjustment and preventing the device from affecting the accurate monitoring of wind direction due to untimely or excessive adjustment, ensuring that the device can adjust the detection angle in real time according to wind direction changes. By analyzing wind data through the analysis module, the inertial impact on the wind vane is determined to avoid the inertial effect causing the wind speed detection fan's windward angle to not remain perpendicular to the actual wind direction, affecting the accuracy of wind direction detection. By judging the deflection angle adjustment and determining whether the deflection angle adjustment is affected by the wind speed, the operating status of the equipment can be more comprehensively understood, detection errors caused by wind speed changes can be prevented in advance, and more effective early warning and protection against extreme weather can be achieved.

10. An early warning method for an atmospheric environment monitoring emergency early warning device according to any one of claims 1 to 9, characterized in that: The early warning method includes the following steps: Q1: After the early warning device is fixed in position by the fixing plate (1), the wireless communication module (15) and the intelligent control components in the main control board (11) cooperate with the intelligent device to monitor the outdoor atmospheric changes; Q2: When the wind vane (14) is rotated by the wind, the analysis module analyzes the frequency of wind direction changes, and the analysis module analyzes the time required for adjustment and compares it to determine whether an adjustment operation is required when a wind direction change signal is generated; when it is determined that adjustment is required, a wind direction adjustment signal is generated based on the inertial effect generated by the analyzed environmental wind data and transmitted to the execution module; Q3: The execution module controls the first motor (4) and the second motor (7) to synchronously drive the articulated seat (5) and the articulated frame (6) to rotate, thereby adjusting the windward angle of the wind speed detection fan (13) to always be perpendicular to the actual wind direction; the speed sensor (9) and the humidity sensor board (12) respectively detect the speed of the wind speed detection fan (13) and the atmospheric humidity, and the main control board (11) determines whether the warning condition is met based on the built-in algorithm and the terminal setting, and controls the warning device to issue a warning when the warning condition is met.
