Abstract
The invention provides a power frequency electric field detection device comprising an electric field detection probe, a sealing housing, a first hygrometer, a first thermometer, a second hygrometer, a second thermometer, a first controller, and a second controller. When a difference value between a first humidity signal and a preset value exceeds a predetermined error value, and a difference value between a first temperature signal and a preset value exceeds a predetermined error value, a temperature adjusting device or a humidity adjusting device can be switched on. When a difference value between a first humidity signal and a preset value is smaller than a predetermined error value, and a difference value between a first temperature signal and a preset value is smaller than a predetermined error value, the temperature adjusting device and the humidity adjusting device can be switched off, the second controller can be switched on, and at the same time, the electric field detection probe can be switched on at the same time, and then the electric field detection value, the first humidity signal, the first temperature signal, the current ambient temperature value, the current ambient humidity value, the detection time, and the detection position, which are transmitted by the electric field detection probe, can be uploaded to a cloud database in a bound manner.
