The invention discloses an intelligent lock, which comprises a box body, a lock, a mobile terminal and a background control center. The lock comprises a master control chip, a communication module andan electromagnetic lock control module. Two-dimensional code information, a travel switch and a buzzer alarm are arranged on the box body. Two- dimensional code is used instead of traditional unlocking by a key so that the staff does not need to carry a key, and the unlocking permission can be distributed by a background management system, the device inspector, time and other information can beautomatically periodically saved by generating log. The safety index of the box body is improved, the state of the box body can be detected remotely in real time by a mobile device, and timely maintenance and overhaul are convenient. The telecommunication resource management is intelligentized and networked; a new management model is innovated; the management process is perfected; and the efficiency and the level of resource comprehensive management are improved. Compared with the traditional door lock, it is safer and more convenient. The property loss caused by damage and theft of the deviceand the labor costs for maintaining an optical fiber communication device are reduced.
