High-voltage power cable construction operation channel environment monitoring and early warning system

The invention discloses a high-voltage power cable construction operation channel environment monitoring and early warning system. The high-voltage power cable construction operation channel environment monitoring and early warning system comprises a gas detector, a wearable physical sign detection device, a microprocessor, an audible and visual alarm device and a mobile terminal, and the gas detector, the wearable physical sign detection device and the audible and visual alarm device are wirelessly connected with the microprocessor. And the microprocessor is wirelessly connected with the mobile terminal. By collecting gas data, vital sign data and positioning information of wearable sign detection equipment in real time, an operation environment index, a vital sign index and an operation channel environment auxiliary reference index can be calculated in real time, and then an early warning result is analyzed in real time according to the index data. Therefore, the concentration of poisonous and harmful gas i
