Abstract

The embodiment of the invention discloses a soaking method, a device and equipment, wherein, the method comprises: generating low frequency alternating current signal, coupling the low frequency alternating current signal to a sounding electrode through a transformer; judging whether soaking occurs by monitoring the size of resistance between sounding electrodes. As the embodiment of the invention adopts low frequency alternating current sounding signal, electrode corrosion and polarization do not occur on the sounding electrode, thus the monitoring result is correct with no false alarm, and the leading-out distance of the sounding electrode can be effectively increased; the low frequency alternating signal and the monitored medium can be separated by a transformer, thus improving monitoring safety and reliability.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a water immersion monitoring method, device and equipment. Background technique [0002] In environments such as communication base stations and building security, it is necessary to set up a water immersion monitoring device to monitor the environment in real time, in order to give an alarm when water immersion occurs in the environment. A commonly used water immersion monitoring device is called a non-contact photoelectric water immersion monitoring device, such as Figure 1A Shown is a schematic structural diagram of the device, which includes a light-emitting diode A, a probe B and an infrared receiving tube C, and the environment where the probe B is located is the medium D. During monitoring, LED A emits a beam of infrared light with a certain intensity and wavelength, and the infrared light enters probe B, which is a hemispherical plastic shell with a smooth surface an...
