Description

Active waterproof detection method and system for electronic equipment interface Technical Field The present application relates to the field of waterproof detection technologies, and in particular, to an active waterproof detection method and system for an electronic device interface. Background With the wide application of electronic devices, especially in the fields with high precision and high reliability requirements, such as intelligent hardware, industrial control, communication equipment and the like, higher requirements are put on the protection performance of equipment interfaces. The problems of water resistance and moisture resistance, in particular the problem of water vapor invasion, become an important link for guaranteeing the stable operation of equipment. The electronic equipment interface generally has the characteristics of compact structure, dense conductive contacts, tiny space scale and the like, when external water vapor enters the interface through gaps, connectors or connecting parts, the external water vapor is easy to locally condense under the effects of factors such as temperature gradient, electric field distribution, material surface energy difference and the like, and is diffused and migrated along the internal structure of the interface, so that a multi-point and progressive water vapor intrusion state is formed, and the process has obvious dynamic, hidden and nonlinear characteristics. Currently, existing waterproof detection technologies mostly rely on a single vapor sensor or an electrical fault detection means, and the technologies can only send out an alarm when vapor intrusion is serious, and lack accurate tracking of a vapor intrusion source and accurate perceptibility of condensation positions, diffusion paths and evolution processes of vapor in an electronic device interface. The existing method is mainly used for indirectly presuming the existence of water vapor by measuring the humidity change of the external or whole environment of the equipment or based on the result fault signals of short circuit, leakage and the like of an interface, but the condensation and diffusion process of the water vapor in the interface is influenced by multiple factors such as the structural layout, material difference, working state change and the like of the interface, the characteristic of non-uniform and staged development is presented, the traditional sensor is difficult to realize high-sensitivity detection, and the false alarm or leakage phenomenon is serious. In addition, most of the existing water vapor monitoring systems do not consider the accurate tracing of the water vapor intrusion path, and lack dynamic adjustment and active protection mechanisms, so that once the water vapor intrusion occurs, the equipment needs to be recovered for a long time. In summary, in the prior art, due to the lack of the capability of monitoring and positioning the intrusion of water vapor in real time, the water vapor cannot be effectively prevented from entering the device interface in an early stage, and the stability and safety of the device are further affected.
