Problems solved by technology

[0002] In order to protect the safety of property, door locks are the most commonly used devices for people to protect private property or public property in the prior art. Mechanical locks are traditional door lock devices, and the most common ones are tumbler locks and magnetic locks. Generally, a key needs to be used to open the door. If people forget to bring the key, the door lock cannot be opened, and the security of this type of door lock is not high. It can be opened with a simple unlocking tool, and once the key is lost or used, it is easy to open the door. The only solution is to replace the door locks; with the development of electronic technology, electronic magnetic card locks and electronic combination locks have appeared. The appearance of these two locks has improved people's management of door locks to a certain extent, but With the continuous application in practice, the defects of these two locks are gradually exposed. The problem of electronic magnetic card locks is that the information is easy to be copied, the wear between the card and the card reader is large, the failure rate is high, and the safety factor is low. The biggest problem is that passwords are easy to leak; and with the popularization of intelligent mobile terminals and the development of communication technology, people generally carry smart mobile devices with them. The environment around the door lock and the state of the door lock; therefore, it is very necessary to provide a multifunctional intelligent door lock based on terminal control with reasonable structure, convenient operation, diverse functions, high security, and strong real-time
