Low-cost NB-IOT (Narrow Band Internet of Things) wireless intelligent lock

Abstract

The invention discloses a low-cost NB-IOT (Narrow Band Internet of Things) wireless intelligent lock, which comprises a controller, a safety lock, a battery and a communication module, wherein the controller is electrically connected with a biological recognition module, an NFC (Near Field Communication) module, a keyboard module and a storage module; the safety lock comprises a sound and light warning device, a lock body picking detection module and a lock body driving and lock body detection module; the battery is electrically connected with the battery volume detection module; the battery is electrically connected with the controller, the safety lock and the communication module; the communication module also comprises an NB-IOT module and a BLE module. By using the NB-IOT technology, the low-cost NB-IOT wireless intelligent lock has the characteristics that the power consumption is low; the signal coverage range is wide. The BLE module realizes the Bluetooth low energy consumption, so that the electric power is further saved; on one hand, the problem of short service life of the battery power supply equipment such as the intelligent lock is solved; on the other hand, the condition that a gateway needs to be additionally arranged for intelligent lock communication conversion is avoided. The device has the advantages of multifunction, low cost, energy conservation and environment protection.

Description

technical field [0001] The present invention relates to an intelligent lock, in particular to a low-cost NB-IOT wireless intelligent lock. Background technique [0002] The traditional Bluetooth smart lock can only be managed by the mobile phone at close range. After the mobile phone and the lock are far away, it cannot be managed, and some abnormal information of the smart lock cannot be notified to the manager. WIFI locks can be managed remotely, but at present, the power consumption of WIFI chips is generally above 100Ma, and its application to battery-powered smart locks reduces the battery life of its products. The smart gateway solution (zigbee+WIFI, 433+WIFI) smart lock adopts low-power zigbee or 433M wireless radio frequency technology in terms of power consumption technology, which increases the cost of a gateway device in its entire product package, and also needs to rely on home routers In the event of a power outage at home, some abnormal information of the smar...
