In today's era of pursuing efficiency and environmental protection, a seemingly small technology - battery free locks - is quietly revolutionizing the fields of centralized email management and traffic signal control. The battery free lock, with its unique technological advantages, breaks the boundaries of the field and achieves cross scenario technological breakthroughs, bringing new development opportunities to different industries. Battery free lock technology: a smart key with zero energy consumption The battery free lock adopts a passive design, abandoning the traditional lock mode that relies on battery power supply. It utilizes external devices such as electronic keys, smartphones, etc. to provide temporary power during unlocking through technologies such as electromagnetic induction and NFC. This design not only avoids maintenance costs and environmental pollution caused by battery replacement, but also significantly improves the service life and stability of the lock. Taking the common electromagnetic induction battery free lock as an example, when the electronic key approaches the lock body, the coil inside the key generates a changing magnetic field. The induction coil inside the lock body generates current due to electromagnetic induction, which supplies power to the unlocking mechanism and completes the unlocking action. The entire process does not require a built-in battery, and energy is only generated as needed at the moment of unlocking, greatly reducing energy consumption. Innovative application of battery free locks in centralized email management In the field of centralized email management, traditional locks face many challenges. For example, centralized email addresses in residential areas or office buildings are numerous and frequently used. Traditional mechanical locks are prone to problems such as lost keys and damaged lock cores, while battery replacement for electronic locks is cumbersome and costly. The emergence of battery free locks has perfectly solved these problems. The battery free lock can be combined with an intelligent management system to achieve intelligent management of centralized email. Property management or administrators can assign electronic key permissions to different users through management software, easily achieving remote authorization of email, unlocking record query and other functions. When users need to use email, they only need to use an authorized electronic key or mobile phone to approach the lock and quickly unlock it. This approach not only improves the convenience and security of email usage, but also reduces the confusion of key management. After adopting a centralized email management system without battery locks in a large residential area, the complaint rate related to email maintenance decreased by 70%, while saving tens of thousands of yuan in battery replacement and lock repair costs every year. In addition, the environmental characteristics of battery free locks are highly compatible with the green concept advocated by modern communities. The design that does not require batteries avoids the pollution caused by a large number of waste batteries to the environment, contributing to the creation of an eco-friendly community. Key breakthrough of battery free lock in traffic signal control The traffic signal control system is the core hub of urban transportation, and the safety and stability of its equipment are crucial.
