Water inflowing detection sensor, water inflowing protection device and communication device and method

Abstract

The invention provides a water inflowing detection sensor, a water inflowing protection device, a communication device and a method. The water inflowing detection sensor comprises at least two resistance mesh layers, an electric insulation water absorbing plate and a detection circuit, wherein the electric insulation water absorbing plate is located between the resistance mesh layers; each resistance mesh layer is provided with at least one conductive circuit; the electric insulation water absorbing plate is used for absorbing water and isolating the resistance mesh layers; when the electric insulation water absorbing plate absorbs the water, a water absorbing position of the electric insulation water absorbing plate communicates two adjacent resistance mesh layers; the detection circuit is isolated from the electric isolation water absorbing plate; and the detection circuit is connected with the conductive circuits of the resistance mesh layers to be used for collecting an electrical parameter changing value between the resistance mesh layers and confirming water inflowing detection information according to the electrical parameter changing value. The water inflowing detection sensor, the water inflowing protection device, the communication device and the method can be repeatedly used for water inflowing detection and have strong applicability and transpotability.

Description

technical field [0001] Embodiments of the present invention relate to electrical technology, and in particular to a water ingress detection sensor, a water ingress protection device, communication equipment and a method. Background technique [0002] With the development of science and technology, network communication equipment, electrical equipment and other equipment with a large number of electronic components are more and more widely used. The safe operation of such equipment usually requires a dry operating environment. If the equipment enters water, it may cause equipment failure. or damaged. However, it is difficult to ensure waterproofing in the actual installation environment of the equipment, especially in areas with a lot of rain, where leaks and floods often occur in houses. In addition, most equipment uses fans to dissipate heat, and there are many openings, which makes it very easy for water to enter. Therefore, a technology is needed to detect water ingress ...
