Intelligent library management lock based on NB-IOT technology

Abstract

The invention provides an intelligent library management lock based on an NB-IOT technology. Technical problems that networking is complex, power consumption is high and positioning information does not exist when an existing intelligent library management lock builds an Internet of things system are solved. A shell, a battery bin, a control circuit board, a lock cylinder and a lock rope are included. A lock tongue switch detection module and a lock rope on-off detection module are arranged in the lock cylinder. The control circuit board comprises a single-chip microcomputer module, a GPS signal detection module, an NB-IOT communication module, an RFID module and an unlocking execution module. The single-chip microcomputer module is electrically connected with the lock tongue switch detection module, the lock rope on-off detection module, the GPS signal detection module, the NB-IOT communication module, the RFID module and the unlocking execution module. The library management lock canbe widely applied to the warehouse management lock field.

Description

technical field [0001] The present invention relates to the field of Internet of Things terminal equipment, in particular to a smart library management lock based on NB-IOT technology. Background technique [0002] Grain reserves are the basis for responding to emergencies such as wars and natural disasters and maintaining national security and stability.
