Soaking monitoring method, device and equipment

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...

Problems solved by technology

Although this monitoring method can be connected to multiple electrodes for multi-point monitoring, due to the electroplating environment formed between the electrodes, DC voltage and water when water immersion occurs, as the water immersion time prolongs, the cations in the water will Electroplated to the negative plate of the electrode, while the positive plate is easily corroded, resulting in electrochemical corrosion; as the voltage between the two plates increases, when it is higher than the reference voltage of the IC comparator, the indication of the IC comparator The state will be flipped, so false alarms will still occur after long-term use
