Automatic electricity approaching early warning device and early warning method for high-altitude construction equipment

The invention relates to the technical field of early warning and monitoring, in particular to an automatic near-electricity early warning device and early warning method for high-altitude construction equipment, and the device comprises a monitoring host, a power frequency electric field probe, and a near-electricity alarm instrument. The monitoring host is arranged in a cab and is used for receiving numerical values acquired by the power frequency electric field detection device, giving out alarm information and sending the alarm information to the near-electricity alarm instrument; the power frequency electric field probe is arranged on an operation equipment mechanical arm and is used for measuring a power frequency electric field value and sending the power frequency electric field value to the monitoring host; and the near electricity alarm instrument is worn by an operator and is used for receiving the alarm information of the monitoring host and giving an alarm prompt. Compared with the prior art, the
