[0002] At present, power equipment is a core component of the power grid system, playing the role of transmitting and distributing electric energy and changing voltage. Once the equipment fails, it will have an adverse impact on the safe operation of the impact grid and the continuous supply of electricity. In the prior art, the failure of power equipment was analyzed and it was found that the root cause of some failures was that people and vehicles were not aware of the high-voltage danger of power equipment, and they might approach the power equipment unconsciously, causing damage or failure of the power equipment. In addition, animals in nature may come into contact with power equipment due to nesting and foraging, resulting in serious consequences such as short circuit, damage or fire of power equipment.

[0003] In the prior art, warning measures for personnel mainly include installing fences and hanging reflective warning signs. However, warning signs are static and the warning effect is not ideal.

[0040] Optionally, the voice module uses a voice chip to burn the ADC audio tracks of variable frequency ultrasonic and audible sound, and completes the circuit design and assembly of the chip and graphene amplifier. Specifically, the measurement results show that the audio frequency of the audible sound track output by the chip is 720 Hz, the sound pressure is 75 decibels, and the frequency of the variable frequency ultrasonic sound is in the 22 kHz-50 kHz range, and the sound pressure is 110 decibels.
