An intelligent access control system

Abstract

This invention discloses an intelligent access control system, belonging to the field of security monitoring. Addressing the problem that existing access control systems fail in power outages and cannot perceive user intent, this invention includes: an energy wake-up module that uses a piezoelectric transducer to convert the mechanical energy of knocking into electrical energy, switching between full perception, emergency alarm, or energy accumulation modes based on the supercapacitor voltage; a multimodal perception module that collects facial, touch pressure, and environmental data and performs adaptive compensation; a state interpretation module that identifies coercive states by associating facial micro-expressions with touch tremors and identifies attack states by associating vibration spectra with non-biological contact; and a decision execution module that executes normal unlocking, silent alarm, or audible and visual locking accordingly. This invention achieves zero-power standby, passive start-up, surface unlocking and covert alarm in coercive scenarios, and active defense in attack scenarios, significantly improving the energy reliability and security intelligence level of the access control system.
