Early warning protection method and system under high-voltage line, computer equipment and storage medium thereof

ActiveCN112288996AEnsure safetyDifficult to touchMeasurement devicesCharacter and pattern recognitionInformation controlElectric shock

The invention relates to an early warning protection method and system under a high-voltage line, computer equipment and a storage medium thereof. The early warning protection method comprises the following steps: acquiring a detection signal located in a preset range between an infrared emitter and an infrared receiver; when a shielding object exists, determining an ultrahigh object exceeding a preset height based on the shielding object to form shielding information; and controlling an alarm device arranged at the ultrahigh object to send out an alarm signal based on the shielding information. The signal transmitted by the infrared transmitter is shielded by an object, so that the infrared receiver cannot receive the signal transmitted by the infrared transmitter, an ultrahigh object which enters a preset range and exceeds a preset height is determined according to the generated shielding information, and the alarm device sends the alarm signal. Therefore, the ultrahigh object is reminded to exit from the preset protection area of an electric iron tower, the ultrahigh object is not prone to colliding with a high-voltage line, safety of site construction to the electric iron toweris guaranteed, and electric shock accidents are reduced.
