In general, the focus of locks in building intelligence is on electric lock products that are compatible with intercoms and access control systems. The production, application and development of security systems such as intercoms, access control and electric locks are only a few decades old. However, the overall development of architectural hardware locks has a history of more than a thousand years. The development of relatively modern western gated hardware products also has The history of several hundred years, but also in the overall hardware and lock investment in the building, the proportion of electric locks is actually a very small part. In this article, I want to discuss the electric lock products with a wider range of building hardware and lock planning principles. Intelligent building applications. Electric lock product classification At present, the security lock products on the market generally include electric locks (cathode locks), electric locks (anode locks), magnetic locks, and hand-operated electric locks. The following are introduced separately. Electric lock The application of the electric lock must be used in conjunction with the mechanical lock body. This product replaces the lock mechanism of the original mechanical lock. The electronic control part is responsible for the opening and closing of the lock baffle. The current product series is mainly subdivided into European standard or American Standard supports the use of different types of mechanical locks as well as power off or power on to meet fire safety requirements. This kind of lock is mainly applied to single-leaf wooden doors or metal doors with frames around them. With the mechanical locks, it can be beautiful and practical under the condition of controlling the price and cost. Electric plug lock Electric plug lock refers to the lock body installed in a fixed position, relying on the electronic control system to drive the lock latch action to control the door switch of an electric lock, this type of electric lock is also divided into power off and power on series, the main scope of application There are double doors, double-opening doors, and glass doors that do not have a fixed position on the door frame. Magnetic lock Magnetic lock refers to a kind of door control equipment manufactured by using the principle of electromagnetic induction. The system controls the magnetic field through the power supply and the power supply to force the steel plate corresponding to the magnetic lock to achieve the purpose of opening and closing the door. The product is only powered off. This type of lock can be applied to a variety of access doors that are unidirectional, and can be widely used indoors and outdoors. However, the lock body is not aesthetically pleasing, and property protection for important locations is not recommended. Hand control lock This kind of electric lock product is a product that has become popular in recent years. It borrows the principle of the hotel lock and combines the features of safety, beauty, convenience and practicality, providing a better choice for high-end customers. The product is suitable for single-leaf single-opening wooden doors with relatively high decoration requirements. Because it is an electromechanical lock, the transition of the control signal line between the door and the door frame must be considered in the installation process.
